The present invention relates to a code generation apparatus used with an electronic device equipped with a touch panel.
In recent years, electronic stamps of which conductive patterns are formed that can be detected with a capacitive touch panel have become widespread. By holding these electronic stamps over an electronic device (for example, a smartphone) equipped with a capacitive touch panel, the conductors are detected, and the capacitance code defined by the arrangement of the conductive pattern is recognized (see Patent Literature 1 and 2).
Patent Literature 1: Japanese Unexamined Patent Application Publication No. 2015-5275.
Patent Literature 2: Japanese Translation of PCT International Application Publication No. JP-T-2016-505922.
However, with the electronic stamps of Patent Literature 1 and 2, only one fixed conductive pattern can be used.
Therefore, when issuing a plurality of coupons or rewarding points, a plurality of stamps is required. Needless to say, a large number of electronic stamps having different conductive patterns for distinguishing each store, respectively, for issuing coupons or rewarding points is required.
The supplier side of the electronic stamp needs to manufacture electronic stamps having different arrangements of electrodes (conductors) forming the conductive patterns. However, since the molds and mechanisms are changed for the production of each stamp in order to manufacture stamps having different conductive patterns, there is the issue that high costs are required, and the cost for a single electronic stamp is high.
Furthermore, the number of conductive patterns that can be set is limited with the electronic stamp of Patent Literature 1 and other various electronic stamps. Specifically, there are at most several hundred patterns. However, in order to complete payments, reward and erase points, or the like at many different stores, it is necessary to distinguish the stores, and thus a large number of conductive patterns (capacitance codes) are required. This cannot be handled by current electronic stamps. In addition, if an electronic stamp is used as a personal seal, an electronic stamp having much more different codes is required.
The present invention has been made in view of such a situation, to enable switching of a plurality of conductive patterns and to provide a large number of different electronic stamps are regarded as the issues.

As shown in
The number and arrangement of the electrodes 5 arranged on the bottom surface of the code generation apparatus 1, and the number and arrangement of the electrodes 52 to be detected by the touch panel 31 as a conductive pattern is not limited to those described, and any other number and arrangement of electrodes can be used as long as the code recognition apparatus 3 can identify them as pattern codes. However, when the code recognition apparatus 3 is a smartphone, it is preferable that the number of the electrodes 52 to be detected at a time is 5 or less at the maximum. This is to accommodate smartphones that execute control to perform error processing when the code recognition apparatus 3 is a smartphone and the number of coordinates detected simultaneously on the touch panel 31 is set to a maximum of five locations, and if the number of detected coordinates exceeded five. Needless to say, this is not necessarily the case if the code recognition apparatus 3 has a function enabling the detecting of more than five electrodes.

The number and arrangement of the electrodes 52 to be detected by the touch panel 31 as the second conductive pattern 82 are also not particularly limited to those described, and any other number and arrangement of electrodes can be used as long as the code recognition apparatus 3 can identify them as pattern codes. However, when the code recognition apparatus 3 is a smartphone, it is preferable that the number of the electrodes 52 to be detected at a time is 5 or less at the maximum. Needless to say, this is not necessarily the case if the code recognition apparatus 3 is an apparatus having a function enabling the detection of more than five electrodes.
Furthermore, the arrangement and number of the electrodes 52 that are detected by the touch panel 31 for the first conductive pattern 81 and the second conductive pattern 82 can be set independently.
In addition, in a state in the middle of a transition period from the state of
[Overview of a Pattern Code Switching Method]
The code generation apparatus 1 includes a push button switch 60 in an operation unit 6, a first code switch 71 and a second code switch 72 in a setting unit 7, electrodes 5, and a human body contact conductive material 21.
The electrodes 5 may include code electrodes 53 that enable the touch panel 31 to switch between detection and non-detection for the pattern code settings of the first conductive pattern 81 and the second conductive pattern 82, and reference electrodes 54 that are set to always be detectable by the touch panel 31 for all pattern code settings. Reference electrodes 54 are not particularly required when the code recognition apparatus 3 does not need them for code recognition, and it is possible to have all of the electrodes 5 be code electrodes 53.
The push button switch 60, that is the operation unit 6, is an SPDT (one input system, two output systems) type A/B changeover switch that enables switching by a single push button pressing operation of a combination of n poles corresponding to the code electrodes 53.
The C terminals, which are common terminals, are connected to the electrodes 5 with a conductive wire or a conductor, and the A terminals that are ON in the initial state are connected to the first code switch 71 that is in the setting unit 7 for the first conductive pattern 81, and B terminals which become ON when the apparatus is pressed are connected to the second code switch 72 which is in the setting unit for the second conductive pattern 82 by a conductive wire or a conductor.
The push button switch 60 of the operation unit 6 is not limited to a push button switch, and any kind of switching system will be sufficient as long as there is a function to switch from terminals for the setting of the first conductive pattern 81 to terminals for the setting of the second conductive pattern 82 when a predetermined operation is received.
Furthermore, the push button switch 60 of the operation unit 6 can receive push button pressing operations, which are predetermined operations, from the outside of the housing 2 of the code generation apparatus 1.
The first code switch 71 and the second code switch 72 in the setting unit 7 are SPST (one input system, one output system) type ON/OFF slide switches provided respectively for each code electrode 53. The first code switch 71 is connected at one terminal to conductive wires or conductors connected to the A terminals of the operation unit, and at the other terminal to conductive wires or conductors connected to the human body contact conductive material 21. The second code switch 72 is connected at one terminal to conductive wires or conductors connected to the B terminals of the operation unit, and at the other terminal to conductive wires or conductors connected to the human body contact conductive material 21.
The first code switch 71 and the second code switch 72 of the setting unit 7 are not limited to slide switches, and any kind of switching system will be sufficient as long as there is a function to select detected electrodes 5 and set pattern codes by having the other side of the terminals connected to electrodes 5 at positions detected by the touch panel 31 as a first conductive pattern 81 and a second conductive pattern corresponding to a pattern code be connected to the human contact conductor 21, and having the other side of the terminals connected to electrodes 5 at positions not detected be disconnected from the human contact material 21.
In addition, the setting unit 7 may be configured so that the first code switch 71 and the second code switch 72 can each be set from the outside of the housing 2 of the code generation apparatus 1, or either one or both of the code switches may be configured so that they cannot be set from the outside.
The human body contact conductive material 21 is provided so as to be contactable from the outside of the housing 2 of the code generation apparatus 1 and connects all of the conductive wires or conductors connected to the mentioned other terminals of the setting unit 7. Furthermore, in a case where the reference electrodes 54 that are set to always be detected by the touch panel 31 for all pattern code settings are provided, the conductive wires or conductors connected to the electrodes are directly connected to the human body contact conductive material 21.
Furthermore, it is sufficient that the code generation apparatus 1 includes a switching function of the operation unit 6 (push button switch 60) and a selecting function of the setting unit 7 (first and second code switches 71 and 72) between the electrodes 5 and the human body contact conductive material 21, and the order of connection may be the electrodes 5, the setting unit 7, the operation unit 6, and the human body contact conductive material 21.
Furthermore, it is possible to only provide the switching function of the operation unit 6, or to only provide the selection function of the setting unit 7.
In STEP 1, when the code generation apparatus 1 is brought into contact with the touch panel 31 while touching the human body contact conductive material 21 of the housing 2 with a human hand, for example, No. 2 of the electrodes 53 is connected to the human hand with low impedance via the human body contact conductive material 21, the switch 2 of the first code switch 71, and the A and C terminals of the push button switch 60, and is detected by the touch panel 31 by the change in capacitance between the touch panel 31 and the electrode 53. Furthermore, since No. 0 of the reference electrodes 54 is directly connected to the human hand via the human body contact conductive material 21 with low impedance, it is similarly detected by the touch panel 31. Providing the reference electrodes 54 makes it easy to specify the orientation of a conductive pattern and the pattern code.
Although the parasitic capacitance between the electrode 53 and the first code switch 71 changes the capacitance between the touch panel 31 and the electrode 53, since the switch 1 of the first code switch 71 is OFF for No. 1 of the electrode 53, it can be prevented from being detected by the touch panel 31 by suppressing the amount of change in capacitance between the touch panel 31 and the electrode 53 due to parasitic capacitance to the detection threshold or to less.
From these, a pattern code of the first conductive pattern 81 in which the electrodes Nos. 0 and 2 are detected by the touch panel 31 is generated.
In STEP 2, the code generation apparatus 1 is pressed against the touch panel 31 while the human body contact conductive material 21 of the housing 2 is being touched by a human hand, for example, which is a predetermined operation, and when the two connections between A terminals and C terminals of the push button switch 60 are switched to connections on the B terminal sides, since the switch 1 of the second code switch 72 is ON and the switch 2 is OFF, No. 1 of electrodes 53 is connected to the human body contact conductive material 21, and No. 2 of electrodes 53 is disconnected by the switch 2 of the second code switch 72. Also, the connection relationship of No. 0 of the reference electrodes 54 does not change from STEP 1.
For this reason, a pattern code of the second conductive pattern 82 in which the electrodes Nos. 0 and 1 are detected by the touch panel 31 is generated.
In addition, in order to prevent the temporary generation of a pattern code differing from the first and second conductive patterns 81 and 82 during the transition from STEP 1 to STEP 2, and to prevent having the code recognition apparatus 3 make a misrecognition, and to avoid having the code recognition apparatus 3 detect too many electrodes 53 simultaneously and violate the restriction on the maximum number of multi-touches that the touch panel 31 can simultaneously detect, it is desirable to adopt the so called non-shorting type switching method where a state which is not detected by the touch panel 31 is formed by making a state where neither the A terminals or the B terminals are connected to the C terminals and all of the electrodes 53 other than the reference electrodes 54 are disconnected from the human body contact conductive material 21 during the process of pressing the push button switch 60.
For these reasons, it is preferable that the various switches of the operation unit 6 that can switch the conductive patterns be of a non-shorting type switching method.
[Overview of a Pattern Code Decoding Method]
By generating electrode conductive patterns, for example, by the two methods below, as for the first and second conductive patterns 81 and 82 generated by the code generation apparatus 1, the codes can be identified as pattern codes and information can be acquired by code recognition apparatus 3.
As a first pattern coding method, there is a method in which the first pattern code is determined from the detected position information of the electrodes 52 (hereinafter referred to as the ON electrodes 52) of the first conductive pattern 81 detected by the touch panel 31, and in which in addition, the second pattern code is determined from the position information of the arrangement and relative positions of the ON electrodes 52 of the second conductive pattern 82 which are determined based on the arrangement and relative positions of each electrode 5 obtained, with the first conductive pattern with the ON electrodes 52 as a reference pattern.
In this method, for example, since the order of the generation of the first conductive pattern 81 and the second conductive pattern 82 is determined by a predetermined operation of pressing, this method can be applied when the first conductive pattern 81 is generated prior to the second conductive pattern 82. In the case of this method, since there is no restriction on the conductive pattern with respect to the arrangement of the plurality of ON electrodes 52 to form a unique pattern code for the second electrode pattern 82, the number of second conductive patterns 82 that can be selected as compared with that of the first conductive pattern 81 increases significantly. Since the total number of pattern codes is the multiplication of the plurality of first conductive patterns 81 and second electrode patterns 82, the total number of pattern codes can be dramatically increased.
The second pattern coding method is a method of determining the first pattern code and the second pattern code respectively from the first conductive pattern 81 and the second conductive pattern 82 independently, from the position information of respectively detected ON electrodes 52 with the first conductive pattern 81 and the second conductive pattern 82 treated as independent patterns. This method is applied when the generation order of the first conductive pattern 81 and the second conductive pattern 82 can be arbitrarily selected in a configuration in which the first conductive pattern 81 and the conductive pattern 82 can be switched, depending on whether or not the human body contact conductive material 21 which is provided in a plurality is touched, as in, for example, the sixth and seventh embodiments described later.
Furthermore, needless to say, the second pattern coding method can also be applied to the case of the code generation apparatus 1 shown in
With reference to

(Step E2) In the code recognition with five detection points, first of all, the code recognition apparatus 3 finds the starting point PS and the end point PE (P5 and P1 in this modification example) constituting the longest line segment L1 connecting two detection points. The angle of the line segment connecting the two points PS and PE with PS as the starting point with respect to the Y′ direction of the touch panel when the code generation apparatus 1 is placed at an angle is θ′=tan−1 {(Y1′−Y5′)/(X1′−X5′)}.
(Step E3) Using PS as the coordinate origin, the code recognition apparatus 3 calculates the relative coordinate values of the other four detection points normalized with L1, ΔP1 {ΔX1′=(X1′−X5′)/L1, ΔY1′=(Y1′−Y5′)/L1}, ΔP2 {ΔX2′=(X2′−X5′)/L1, ΔY2′=(Y2′−Y5′)/L1}, ΔP3 {ΔV′=(X3′−X5′)/L1, ΔY3′=(Y3′−Y5′)/L1}, ΔP4 {ΔX4′=(X4′−X5′)/L1, ΔY4′=(Y4′−Y5′)/L1}.
Furthermore, as shown in
(Step E4) Then, the code recognition apparatus 3 calculates in advance the standardized coordinate values of the three points excluding the starting point PS and the end point PE constituting the longest line segment L1, and they are stored in the standardized coordinate-code number table in association with the angle θ1 of the longest line segment L1 with respect to the positive direction (Y-axis direction) of the code generation apparatus 1. The code recognition apparatus 3 collates the angle θ1 of the longest line segment L1 with respect to the positive direction (Y-axis direction) of the code generation apparatus 1 and the angle θ1 of the longest line segment stored in the standardized coordinate-code number table.
The predetermined errors are largely influenced by the detection resolution of the touch panel, and the errors are absolute values of actual sizes. On the other hand, since each detection coordinate is standardized by the longest line segment L1 connecting two detection points, the error range is not constant and depends on the ID (that is, the distance of L1). Therefore, as shown in
(Step E4) Then, the code recognition apparatus 3 specifies a pattern code (ID) and a touch position number from the obtained coordinate values, and executes a corresponding processing.
(Effect) As described above, the code recognition apparatus 3 can obtain a pattern code corresponding to a code number when coordinates are collated with those of the standardized coordinate-code number table of
[Overview of the Examination of Restrictions of Switchable Electrodes]
From the description of the pattern code switching method, with a code generation apparatus 1 capable of switching codes, it can be found that it is important to reduce the capacitance between the electrodes 5 and the touch panel 31 including the parasitic capacitance of the electrodes 5 that are in contact with the touch panel 31, so that the amount of change in the capacitance of the touch panel 31 does not exceed the detection threshold although they are disconnected from the human body contact conductive material 21 by a push button switch of the operation unit 6 or a second code switch 72 of the setting unit 7.
For this reason, the capacitance allowed for the electrodes not to be detected by the touch panel was evaluated.
The circuit board is a PCB circuit board having a thickness of 1.5 mm, and electrodes having a diameter of 8 mm are on the bottom surface in an arrangement of 3×4 at intervals of 12 mm in the vertical direction and 14 mm in the horizontal direction. The electrodes are connected to land patterns with a diameter of 3 mm on the upper surface via through holes, and circuit board wiring on the upper surface for electrodes to have parasitic capacitance is formed so that it overlaps with the electrodes in (A), and it is routed with a 0.1 mm wide wiring so as not to overlap with the electrodes in (B).
In the evaluation method, the land pattern of the outer five electrodes are connected with additional wiring, and electrodes with touching of an end of the wiring by the human body was set to be in a detection state (ON) and electrodes with the connection of the land pattern of the single central electrode and wiring on the circuit board, and having parasitic capacitance was set to be in a non-detection state (OFF). Evaluation of the electrostatic capacitance of the central electrode was done for maintaining a state where the one central electrode remains undetected at all times while the five outer electrodes are detected normally by changing the wiring length of circuit board when the bottom side is brought into contact with the touch panel so that the surfaces overlap.
Determination of electrode detection/non-detection by the touch panel was performed by determining whether or not the touch panel correctly returned output of the coordinates of the electrodes upon having the circuit board for evaluation brought into contact by placing it vertically and horizontally 10 times each.
The notations in Table 1 are 5: normal detection for all times, 3: normal detection for 10 times or more, 2: normal detection for less than 10 times, 1: detection for less than 10 times with partial missing of the 5 detection electrodes, 0: no detection for all times, E: touch panel error output returned for 10 times or more.
As for the code recognition apparatus 3 and the usage environment, the four conditions applied are an iPhone (registered trademark) 6 held in the hand, an iPhone placed on a cork board which is most difficult for the detection of electrodes, an iPad (registered trademark) placed on a steel desk, and an iPad placed on a cork board.
As a result of the evaluation, as shown in Table 1, it was found that if the capacitance between the electrode and the touch panel is 5 pF or less under either one of the conditions with an iPhone (registered trademark) 6 with both evaluation circuit boards A and B, the electrodes are not detected by the touch panel. Furthermore, it was found that even when there are detected electrodes are densely arranged, such as the five detected electrodes, the coordinates are correctly detected by the touch panel. By setting the specification based on the evaluation result, a code generation apparatus capable of switching codes can be created.
Furthermore, a strap through hole 23 is provided on the side surface opposite to the protrusion 22. The bottom surface 4 has a first circuit board 41 formed of a non-conductor, and the electrodes 5 provided on the bottom surface of the first circuit board 41 are arranged in a 4×4 array on the same plane as the bottom surface 4. The number and arrangement of the electrodes 5 are not limited to those described, and can be increased or decreased as appropriate according to the number of required code patterns.
In addition, regarding the electrodes 5 provided on the bottom surface of the first circuit board 41, all of the electrodes 5 need only be on the same plane, and the bottom surface of the first circuit board 41 may be formed in a convex shape.
Still further, although the electrodes 5 are exposed on the bottom surface 4 of
As shown in
The first conductive pattern 81 is formed by a method in which the second circuit board electrode terminals 62 connected to the electrodes 5 of the first substrate 41 provided on the upper surface of the second substrate 61 and only terminals corresponding to the electrodes of the first conductive pattern 81 among pattern setting terminals 73 detected by the touch panel are connected with solder joints 74. The solder joint 74 corresponds to the ON function of the first code switch 71 of the setting unit 7. The pattern setting terminal 73 is connected to a first contact 67 through a through hole, and the first contact 67 opposes a movable electrode 25. The movable electrode 25 is connected to the human body contact conductive material 21 in a state in which it is separable from the housing 2 by the conductor of the housing 2.
The second conductive pattern 82 is formed by turning ON the slide switches 75 that are the second code switches 72 of the setting unit 7 provided for each electrode 5 provided on the upper surface of the third circuit board 63. Since the slide switches 75 are provided on the third circuit board 63 inside the housing 2, the housing 2 and the third circuit board are detachably screwed together. The second conductive pattern 82 is changed by removing the screws, opening the housing 2, and changing the ON/OFF states of the slide switches 75. Contacts 66 that can connect and disconnect the common connection lines 65 on the third circuit board 63 with the human body contact conductive material 21 provided in the housing 2 in accordance with the assembly and removal of screws are provided.
The operation unit 6 performs a switch from the first pattern code to the second pattern code by having the third circuit board 63 detachably attached to the central shaft 24 inside the housing 2, and movable electrodes 25, conductors provided on the bottom surface side of the second circuit board 61 and passes through the center holes of the third circuit board 63 and the second circuit board 61 be movable between the second circuit boards 61 in accordance with the pressing operation to the causing 2. The movable electrodes 25 are connected to the human body contact conductive material 21 on the surface of the housing 2 through the central shaft 24.
In the state of STEP 1 with the apparatus in contact with the touch panel 31, as shown in
In the state of STEP 1, among the electrodes 5, those without the solder joint 74 are made so that the capacitance between the electrodes 5 on the bottom surface of the first circuit board 41 and the touch panel 31 including the parasitic capacitance of the conductors to the pattern setting terminals 73 connected from the electrodes 5 is in a range not exceeding the detection threshold of the touch panel 31.
As a result, only the electrodes 5 having the solder joint 74 between the second circuit board electrode terminal 62 and the pattern setting terminal 73 become conductive to the human body contact conductive material 21, and the first conductive pattern can be generated. Next, in the state of STEP 2 with the apparatus pressed on the touch panel 31, as shown in
As a result, only the electrodes 5 with the slide switch 75 of the third circuit board 63 ON are in a conduction state up to the human body contact conductive material 21, and the second conductive pattern can be generated.
The push button switch 60 has a drive mechanism using a spring. The drive mechanism itself is not particularly limited to those described, and a general push button switch mechanism can be used. However, as described in the “Overview of a pattern code switching method” section, a non-shorting type switching method is preferable, since it is necessary that at least different electrodes 5 are not simultaneously detected by the touch panel 31 upon switching of the first electrode pattern 81 and the second electrode pattern 82.
Furthermore, when the code generation apparatus 101 is brought into contact with the touch panel 31, in order to prevent a situation where the first conductive pattern 81 is not properly detected by the touch panel 31 due to a pressing force applied to the push button switch 60 before the bottom surface 4 makes evenly contact, it is preferable to have the initial torque for driving the push button be appropriately increased for the push button switch 60 and a clicking can be felt.
Furthermore, the driving mechanism may adopt either operation methods between a momentary operation method or an alternate operation method.
When the push button switch 60 is pressed, if 16 locations consisting of the second circuit board side second contacts 68 on the top surface of the second circuit board 61 and the third circuit board side second contacts 69 on the bottom surface of the third circuit board 63 are brought into contact simultaneously, the charge stored in the parasitic capacitance up to terminals of one side of switches 75 of the third circuit board 63 which are OFF is transmitted to electrodes 5 that ought not be detected at the same time, and the capacitance of the touch panel 31 may be changed widely over the entire region of the bottom surface 4 of the touch panel 31 in contact even though by a little to cause erroneous detection. For this reason, the stroke length of the push button switch is increased, the distance between the contacts 68 and 69 is increased, the distance between the 16 contacts is changed for sets of a plurality of contacts, and the switching of the contacts 68 and 69 at the time of pressing is implemented stepwise, and thus it is possible to prevent erroneous detection.
Next, the number and arrangement of electrodes 5 to be detected by the touch panel 31 of the first conductive patterns 81 and the second conductive patterns 81 set by the setting unit 7 can be made variable for respective conductive patterns within a range in which the code recognition apparatus 3 can recognize them as pattern codes. For example, a specification in which five electrodes are detected for the first conductive pattern 81 and only two for the second conductive pattern 81 are detected is possible. As a result, the number of pattern codes that can be selected can be greatly increased.
In addition, among the plurality of first and second conductive patterns 81 and 82, the number of electrodes 5 to be detected by the touch panel 31 can be fixed. With this specification, the number of pattern codes that can be selected is reduced compared to when they are variable. However, detection error determination can be made based on the number of detected electrodes 5 and thus the reliability of the code recognition system can be improved.
For example, the first and second conductive patterns 81 and 82 have pattern code specifications in which four and five electrodes 5 are detected for any pattern code, respectively, and in the code decryption by the code recognition apparatus 3, when the first and second conductive patterns 81 and 82 are detected and decoded, respectively, if the number of the detected electrodes 5 are other than 4 or 5, respectively, it is possible to process all as errors, and thus it is easy to extract misdetections of the code.
As a result, for the code generation apparatus 101 of the first embodiment, a single code generation apparatus 101 can generate a plurality of pattern codes by switching between the first conductive pattern 81 and the second conductive pattern 82, and thus the number of pattern codes that can be generated greatly increased.
Since setting can be changed for the first conductive pattern 81 in a soldering operation during assembly, and the second conductive pattern can be changed by switching the slide switch ON and OFF after the product is completed, there is no need to change the mold or circuit board for each pattern code, and manufacturing costs for changing the pattern code set to the product in the manufacturing process can be greatly reduced and the TAT (turnaround time) for making changes can be greatly shortened.
Furthermore, since settings for the second conductive pattern are changeable by an extremely simple method of switching the slide switch ON and OFF after the product is completed, by disclosing the code setting method to the customer, the customer could also change the code setting, thus convenience for the customer can be improved.
In the present embodiment, although settings for electrodes 5 to be detected by touch panel 31 for the first conductive pattern 81 was described as only the corresponding second circuit board electrode terminal 62 on the upper surface of the second circuit board 61 and the pattern setting terminal 73 being connected by the solder joint 74, a connection method using a jumper wiring in the place of the solder joint 74 may be used. Still further, in the place of solder joint 74, a method of selectively connecting in advance with the wiring pattern of the second circuit board 61 may be used. As a result, in the assembly of the apparatus, the soldering operation is not required, and by the reduction of assembly work processes and the reduction of erroneous setting during assembly, the manufacturing costs can be reduced.
In the present embodiment, the method of switching the first conductive pattern 81 set by the setting unit 7 to the second conductive pattern 82 by a single operation (for example, one stroke) by the operation unit 6 is described. However, the number of times of-switching is not limited to two stages.
For example, the electrodes 5 of the second conductive pattern 82 to be detected by the touch panel 31 are divided into two sets, and by increasing the distance between the second circuit board side second contacts 68 on the upper surface of the second circuit board 61 of the push button switch 60 of the operation unit 6 and the third circuit board side second contacts 69 on the bottom surface of the third circuit board 63, and dividing the contact distance into the two groups of narrow and wide gaps, and by making the pressing mechanism also into two stages, it is possible to switch between three stages of patterns, by detection of the first conductive pattern 81 before pressing, a pattern of a combination of electrodes 5 of the narrow contact distance side of the second conductive pattern 82 of the first pressing stage, and the second conductive pattern 82 of the second pressing stage with all of the electrodes 5 for detection.
Furthermore, for example, multi-stage switching is possible by the switching between the second circuit board side second contacts 68 on the upper surface of the second circuit board 61 and the third circuit board side second contacts 69 on the bottom surface of the third circuit board 63 by pressing of the push button switch 60 of the operation unit 6, by adapting a slide switch or a dial switch of multi-circuit multi-contact to each electrode 5, providing a plurality of the second circuit board side second contacts 68 on the common terminal side and the third circuit board side second contacts 69 (and the configuration of the setting unit 7 thereafter), connecting on the switching contact side of the slide switch or the dial switch, and switching the slide switch or the dial switch by a predetermined operation.
Still further, by providing an electrical control circuit for operating a relay in the operation unit 6, and with the relay of the push button switch 60 of the operation unit 6, contacts on the electrodes 5 side of the first and second conductive patterns 81 and 82, and contacts on the common terminal side of the human body contact conductive material 21 can be switched.
As shown in
As described above, with the code generation apparatus 102 of the second embodiment, erroneous detection by touch panel 31 at the time of a code switching operation can be reduced by reducing the parasitic capacitance of the electrodes 5 by reducing the size of movable contacts 25 and reducing the electrode areas.
In addition, since the outer shape of the code generation apparatus 102 can be given flexibility, the design of the product can be improved.
Also, needless to say, the number of pattern codes can be greatly increased by switching between the first conductive pattern 81 and the second conductive pattern 82 as in the case of a code generation apparatus 101 of the first embodiment. Since the setting of a code pattern can be changed at the time of assembly or after completion of the product, the manufacturing costs for changing the pattern code can be reduced, TAT for making changes can be shortened, and convenience for the customer can be improved.
In addition, descriptions of parts other than the operation unit 6 and the setting unit 7 that are not significantly different from those of the code generation apparatus of the first embodiment are omitted.
As shown in
Electrodes 5 are arranged on the bottom surface of the first circuit board 41 are arranged evenly in a 4×4 array. The number and arrangement of electrodes 5 are not limited, and it is possible to increase or decrease as appropriate according to the number of required code patterns.
Electrodes 5 on the bottom surface of the first circuit board 41 are connected to contacts 42 provided in two rows on both the left and right sides of the upper surface with conductive wires on the upper surface via through holes. Pin headers 43, which are bar-shaped metals extending from the second and third circuit boards 61A and 63A, are pressure welded and connected to the contacts 42. The pin headers 43 solder-connected to the second and third circuit boards 61A and 63A are connected to the pin connector female terminals 44 and 45 in respective circuit boards. As a result, each electrode 5 is connected to the corresponding pin connector female terminals 44 and 45 on the second and third circuit boards 61A and 63A.
The selection of the electrodes 5 detected by the touch panel 31 by the setting unit 7 is performed by switching of the pin connector.
The first conductive pattern 81 is formed by selectively connecting pin connector male terminals 45 provided at the leading end of the third circuit board 63A connected to a flat spring contacts 47 provided on the bottom surface of the third circuit board 63 to pin connector female terminals 45 connected from each electrode 5 of the first circuit board 41 provided on the upper surface of the third circuit board 63A. The connection between a pin connector male terminal 49 and a pin connector female terminal 45 corresponds to the ON function of the first code switch 71 of the setting unit 7.
The same number as the maximum number of electrodes 5 detected by the touch panel for the first conductive pattern 81 is provided from the flat spring contacts 47 to the pin connector male terminals 49, and all of the pin connector male terminals 49 have conductive wires long enough to connect with all pin connector female terminals 45. When the number of electrodes detected by the touch panel of the first conductive pattern 81 is variable, the remaining pin connector male terminals 49 are in an open state upon connecting the required pin connector male terminals 49 to pin connector female terminals 45 when the electrodes 5 are of a conductive pattern with a number less than the above mentioned maximum number. For this reason, the pin connector female terminals 45 in the open state may be provided for fixing the excess pin connector male terminals 49 on the upper surface of the third) circuit board 63A.
Similarly to the first conductive pattern 81, the second conductive pattern 82 is formed by selectively connecting pin connector male terminals 48 provided at the leading end of the conductive wire on the bottom surface of the second circuit board 61A connected to the flat spring contact 46 provided on the upper surface of the second circuit board 61A to the pin connector female terminals 44 connected from each electrode 5 of the first circuit board 41 provided on the upper surface of the second circuit board 61A. The connection between a pin connector male terminal 49 and a pin connector female terminal 45 corresponds to the ON function of the second code switch 72 of the setting unit 7.
As shown in
Next, as in the first embodiment, the operation unit 6 switches from the first pattern code 81 to the second pattern code 82 by moving conductive movable electrodes 25 connected to a human body contact conductive material 21 outside of the housing between the flat spring contacts 46 and 47 of the second and third circuit boards 61A and 63A along the central shaft 24 inside the housing 2 according to the pressing operation of the housing 2.
By inserting a central shaft 24 with movable contacts 25 fixed thereto into the U-shaped grooves of the second and third circuit boards 61A and 63A, the movable electrodes 25 are placed between the flat spring contacts 46 and 47 of the second and third circuit boards 61A and 63A. the U-shaped groove is fixed by a groove fixing component (not shown) after the central shaft 24 is inserted, and the central shaft 24 and the movable electrodes 25 are placed so that the flat spring contacts 46 and 47 are freely movable on the centers of circuit board planes of the second and third circuit boards 61A and 63A. The movable electrodes 25 are connected to the human body contact conductive material 21 of the housing 2 (not shown) by a conductive wire or a conductor.
In STEP 1, a state in which a stamp is placed on the touch panel 31 before pressing, the movable electrodes 25 are in an upper position by the spring of a push button switch (not shown) and is connected to the flat spring contact 47 on the bottom surface of the third circuit board 63A, and only the electrodes 5 corresponding to the pin connector female terminals 45 inserted with the pin connector male terminals 49 connected from the spring contacts 47 become electrically connected to the human body contact conductive material 21, and the first conductive pattern 81 can be generated.
Next, in STEP 2, a state in which a stamp is pressed onto a touch panel 31, the movable electrodes 25 and the flat spring contact 46 on the upper surface of the second circuit board 61A are connected by pressing, and only the electrodes 5 corresponding to the pin connector female terminals 44 inserted with pin connector male terminals 48 connected from the flat spring contacts 46 become electrically connected to the human body contact conductive material 21 and the second conductive pattern 82 can be generated.
As a result, for the code generation apparatus 103 of the third embodiment, by making the second and third circuit boards 61A and 63A sharable, and adopting a method of switching where the pin connectors corresponding to the number of the electrodes 5 for detecting switch switching of the setting unit 7 are switched, the number of parts can be greatly reduced and the number of processes for the assembly can also be reduced, and thus, the manufacturing costs can be further reduced.
Needless to say that the number of pattern codes can be greatly increased by switching between the first conductive pattern 81 and the second conductive pattern 82 as in the case of the code generation apparatus 101 of the first embodiment. Since the code pattern setting can be changed after the product is completed, the manufacturing costs for changing the pattern code can be reduced, the TAT for making changes can be shortened, and convenience for the customer can be improved.
As shown in
The code generation apparatus 104 has a shape similar to that of a square stamp, and a push button of the push button switch 60 that is the operation unit 6 is provided as one with the human body contact conductive material 21 on the upper surface of the housing 2. Contact points of the push button switch 60 and the main body moiety of switches for driving mechanisms and the like are provided in the bottom part of the housing 2 in order to reduce parasitic capacitance of the electrodes 5. By placing the housing 2 on the touch panel 31 and pressing the push button while the human body contact conductive material 21 is touched by the hand, two types of pattern codes, the first conductive pattern 81 and the second conductive pattern 82 can be generated sequentially. On the side surface of the housing 2, a protrusion 22 is provided as an indicator of direction when placing a stamp on a touch panel. The bottom surface 4 has a first circuit board 41 made of a non-conductor, and eight electrodes 5 are provided on the bottom surface of the first circuit board 41 arranged a 3×3 array on the same plane as the bottom surface 4. (One location is vacant.) The number and arrangement of the electrodes 5 are not limited, and can be increased or decreased as appropriate according to the number of required code patterns.
Furthermore, the external form is not limited to a square, and any specification may be adopted as long as the stamp can be placed on a touch panel and the plurality of electrodes 5 can be evenly brought into contact with the surface of the touch panel. In
A lid component 23 that can be opened and closed by a screw 24 is provided on the side surface opposite to the protrusion 22 of the housing 2 and a fourth circuit board 730 is disposed so that when the lid component 23 is opened, the Dip switch 72 of the second code switch is exposed. As a result, it is possible to easily switch the second code switch 72 and change the second pattern code simply by opening the lid component 23 of the housing 2. Furthermore, instead of affixing the lid component 23 with the screw 24, a nail may be provided at the edge of the lid component 23 like the lid of a battery storage unit provided in what is referred to as a small electronic device, and a nail receiving hole may be provided on the housing 2 side to make it easy to open and close.
In addition, opposite to these methods, in order to prevent the second code switch 72 from being easily changed, it is possible to make the screw 24 have a screw head with an uncommon shape such as a hexagonal hole or a hexalobular hole.
The setting unit 7 adopts the method of switching settings by a Dip switch.
The terminal 1 side of each switch of the first code switch 71 is connected to each terminal on the third circuit board 63 corresponding to each electrode 5 by a conducting wire 761, and the terminal 1 side of each switch of the second code switch 72 is connected to each terminal on the second circuit board 61 corresponding to each electrode 5 by a conducting wire 762. The other terminal side of each switch of the first and second code switches 71 and 72 is connected to all of the common wiring on the fourth circuit board 730 and is connected to the human body contact conductive material 21 from the terminal 74 with a conductive wire. The wirings 761 and 762 may be connected to the second circuit board 61 and the third circuit board 63, respectively, using printed wiring on the fourth circuit board 730 after wiring to the bottom portion of the fourth circuit board 730.
Next, the operation unit 6 switches between the first conductive pattern 81 and the second conductive pattern 82 by the drive mechanism of the push button switch 60 provided in the lower part of the housing 2. As shown in
In STEP 1, a state in which a stamp is placed on the touch panel 31, the movable electrodes 25 are in an upper position by the spring of a push button switch (not shown), and the second contact 69 provided for each electrode 5 on the bottom surface of the third circuit board 63 and the movable electrodes 25 are connected, and the second circuit board side first contact 67 on the upper surface of the second circuit board 61 provided for each electrode 5 and the plate spring terminal 26 of the movable electrodes 25 are disconnected. As a result, only the electrodes 5 set to the ON side with the first code switch 71 will be in a conduction state to the human body contact conductive material 21, and a first conductive pattern can be generated.
Next, in STEP 2 in the state where the stamp is pressed onto the touch panel 31, by the pressing, the movable electrodes 25 are in a lower position, and the first contacts 67 on the upper surface of the second circuit board 61 and the flat spring terminals 26 of the movable electrodes 25 are in a disconnected state, and the third circuit board side second contacts 69 on the bottom surface of the third circuit board 63 and the flat spring terminals 26 of the movable electrodes 25 are in a connected state. As a result, only the electrodes 5 set to the ON side by the second code switch 72 will be in a conduction state to the human body contact conductive material 21, and a second conductive pattern can be generated.
As a result, for the code generation apparatus 104 of the fourth embodiment, by providing the lid component 23 that can be opened and closed by the screw 24 on the back side of the housing 2, and adopting a structure in which the Dip switch 72 of the second code switch is exposed, the second code switch 72 can easily be switched and the second pattern code can be changed, and convenience for the customer can be further improved.
Furthermore, by using an inexpensive Dip switch for the switch of the setting unit 7, it is possible to reduce the cost of parts and reduce the manufacturing costs.
Needless to say, as with the code generation apparatus 101 of the first embodiment, the number of pattern codes can be greatly increased by switching between the first and second conductive patterns 81 and 82, and since the code pattern setting can be changed after the product is completed, the manufacturing costs for changing the pattern code can be reduced, the TAT for making changes can be shortened, and convenience for the customer can be improved.
The setting of a lid 23 that can be opened and closed by a screw 24 on a part of the housing 2, the exposing of the setting unit 7, the use of a Dip switch for the setting unit 7, and the like as in the present embodiment can also be applied to other embodiments such as the first, second, and third embodiments, and the like.
As shown in
For example, when the code generation apparatus 105 is used in a point rewarding service system of a retail chain store, if a function that enables easy change to a necessary pattern code is assigned, the first code patterns that are the first conductive patterns 81 generated in STEP 1 are assigned to the ID codes of each store, and a switch for switching functions is provided so that the operator in the store can easily switch the second code patterns that are the second conductive patterns 82 generated in STEP 2 to code patterns that each correspond to an operation used in a point rewarding service system. For example, a rotation switch 91 for changing numerical point values, a slide switch 92 for switching between point granting and point erasing, and a push button switch 93 for resetting functions are arranged on the side surface of the housing 2 so that operations can be done on the outside of the housing 2.
The code generation apparatus 105 has a shape similar to that of a square stamp, and a push button of a push button switch 60, which is the operation unit 6, is provided with the human body contact conductive material 21 as one on the upper surface of the housing 2. Contact points of the push button switch 60 and the main body moiety of switches for driving mechanisms and the like are provided in the bottom part of the housing 2 in order to reduce parasitic capacitance of the electrodes 5. By placing the housing 2 on the touch panel 31 and pressing the push button while the human body contact conductive material 21 is touched by the hand, two types of pattern codes, the first conductive pattern 81 and the second conductive pattern 82 can be generated sequentially.
A rotary switch 91 enabling the selection from 10 types of code patterns is provided on the side surface of the upper part of the housing 2 of the main body moiety of the switch of the push button switch 60 of the housing 2, and also provided on the side surface of the housing 2 is a protrusion 22 as an indicator of direction for when the stamp is placed on a touch panel, a slide switch 92 for switching between point granting and point erasing, and a push button switch 93 for resetting functions.
The bottom surface 4 has a first circuit board 41 made of a non-conductive material, and nine electrodes 5 provided on the bottom surface of the first circuit board 41 are arranged in a 3×4 array on the same plane as the bottom surface 4, among which electrode 5 No. 0 is a reference electrode 54, an electrode detected by the touch panel 31 regardless of whether STEP 1 or STEP 2 is in operation. (No electrode is placed in the remaining three places of the arrangement.) The number and arrangement of the electrodes 5 are not limited, and can be increased or decreased as appropriate depending on the number of code patterns required for ID codes or the like.
Furthermore, the external form is not limited to a square, and any specification may be adopted as long as the stamp can be placed on a touch panel and the plurality of electrodes 5 can be evenly brought into contact with the surface of the touch panel. In
As shown in
The No. 8 electrode 5 is assigned to a push button switch pressing determination electrode 5 for determining whether the current conductive pattern is STEP 1 or STEP 2, is switched only by the push button switch 60, and is connected to the human body contact conductive material 21 when pressed. Is done. When the No. 8 electrode is detected by the touch panel 31, the state is STEP 2.
In the state of STEP 2, No. 1 to 5 electrodes 5 are assigned to numerical value selection electrodes and connected to a rotary switch 91. In regards with the rotation switch 91, two of the five electrodes 5 are selected by a mechanism described later, connected to the common terminals of the rotation switch 91, and connected to the human body contact conductive material 21 via one terminal A of the push button switchover switch 93, and thus 10 types of numerical codes are selected. The numerical codes are assigned to arbitrary numerical values by the code recognition apparatus 3. The No. 6 electrode 5 is assigned to a function setting electrode and is connected to one terminal of the slide switch 92. The other terminal of the slide switch 92 is connected to the human body contact conductive material 21 via one terminal A of the push button switchover switch 93 in the same manner as the common terminal of the rotary switch. For example, when the slide switch 92 is set to ON and the No. 6 electrode 5 is detected by the touch panel 31, a reward point granting function is assigned.
The No. 7 electrode 5 is assigned to the function reset electrode and is connected to the other terminal B of the push button switchover switch 93. When the push button switchover switch 93 is pushed, the No. 7 electrode 5 is connected to the human body contact conductive material 21 and is detected by the touch panel 31. As a result, not only are codes set for electrodes 5 of No. 1 to No. 7, but by pushing the push button switch 60, a second conductive pattern 82 can be generated. by setting the codes of the electrodes 5 up to 7 and pressing the push button switch 60.
Furthermore, the electrodes 5 of No. 1 to 6 are disconnected from the human body contact conductive material by the push button switchover switch 93 and thus are in a state where they are not detected by the touch panel 31. This is to deal with control that performs error processing when the code recognition apparatus is a smartphone and the number of coordinates detectable simultaneously by a touch panel set to a maximum of five is exceeded.
As the drive mechanism of the push button switch 60, the same mechanism as that of the fourth embodiment shown in
On the outer periphery of the rotary switch body 901, a cylindrical numerical value display portion 902 whose outer periphery has the same diameter as that of the housing 2 is fitted maintaining slidability. The outer surface of the numerical value display unit 902 is divided into 10 at equal intervals, and graphics corresponding to numerical values or codes are displayed. Furthermore, two contact fixing portions 903 formed with two vertically extending protrusions provided at two positions 180 degrees rotationally symmetric with respect to the center of the cylinder on the inner periphery of the numerical value display portion 902. At the two contact fixing components 903, the A-row side contact flat springs 910 and the B-row side contact flat springs 911 are fitted and fixed between the protrusions of the contact fixing component 903, respectively. In addition, as shown in
From the arrangement of the 10 A-row terminals 916 and B-row terminals 915 on the cylindrical side surface and the A-row terminal side contacts 914 and B-row terminal side contacts 912 arranged in the numerical value display unit 902, the combination of the selected terminals of the 10 rotary switches is as shown in Table 3.
As a result, the numerical value display unit 902 comes into contact with the rotary switch body 901 elastically at an opposing position by a flat spring, and the sliding operation can be stabilized. In addition, since the portions between the terminals on the side surface of the rotary switch body 901 are expanded toward the outer periphery by the thickness of the projecting wall portion 906 with respect to the terminal surface, they serve as barriers for preventing sliding of the numerical value display portion 902, and thus it does not move by an unintentional touch, and the selection terminals of the rotary switch can be stabilized.
As a result, for the code generation apparatus 105 of the fifth embodiment, each electrode of the first code pattern and the second code pattern can be assigned a function in accordance with the actual method of use by a customer, and by including switches corresponding to them and making the switching of code patterns easy, along with the increase in the attractiveness of the product specifications to increase product value, convenience for the customer is also improved.
Needless to say, as with the code generation apparatus 101 of the first embodiment, the number of pattern codes can be greatly increased by switching between the first and second conductive patterns 81 and 82, and since the code pattern setting can be changed after the product is completed, the manufacturing costs for changing the pattern code can be reduced, the TAT for making changes can be shortened, and convenience for the customer can be improved.
Assigning functions or the like to the setting unit 7 and the operation unit 6 used in the present embodiment at the time of use by using various switches such as a rotation switch and a push button switch, may also be applied to the other embodiments such as the first, second, third, and fourth embodiments and the like.
As shown in
The code generation apparatus 106 has a shape similar to that of a square stamp, and the push button of the push button switch 641 that is the operation unit 6 is provided as one with the human body contact conductive material 211 on the upper surface of the housing 2, and the push button of the push button switch 642 push buttons is provided as one with the human body contact conductive material 212.
Furthermore, the external form is not limited to a square, and any specification may be adopted as long as the stamp can be placed on a touch panel and the plurality of electrodes 5 can be evenly brought into contact with the surface of the touch panel. Although in
As shown in
Each electrode 5 provided on the first circuit board 41 is connected by a conductive wire or a conductor to a C terminal of each slide switch 77 which is a code switch provided on the second circuit board 61. Each terminal 1 of each slide switch is connected to a corresponding first contact 67 by a conducting wire, and each terminal 4 is connected to a corresponding second contact 69 by a conducting wire. The second contacts 67 are opposed to the movable electrodes 251 of the push button switch 641 and the movable electrodes 251 are connected by a conductive wire or a conductor to the human body contact conductive material 212, and the second contacts 69 are opposed to the movable electrodes 252 of the push button switch 642 and the movable electrodes 252 are connected by a conductive wire or a conductor to the human body contact conductive material 212.
For example, when the push button switch 641 is pressed while the human body contact conductive material 211 is touched by the hand, the first contacts 67 and the movable electrodes 251 are connected, and only the electrodes 5 corresponding to each switch slid to terminal 1 side of the slide switch are connected to the human body contact conductive material 211 and detected by the touch panel 31 enabling the generation of the first conductive pattern 81. Also, when the push button switch 642 is pressed while the human body contact conductive material 212 is touched by the hand, the second contacts 69 and the movable electrodes 252 are connected, and only the electrodes 5 corresponding to each switch slid to the terminal 4 side are in contact with the human body contact conductive material 212 and detected by the touch panel 31 enabling the generation of the second conductive pattern 82.
Furthermore, for example, when the push button switches 641 and 642 are pressed together while both human body contact conductive materials 211 and 212 are touched by the hand, the first contacts 67 and the movable electrodes 251 are connected, electrodes 5 corresponding to each switch slid to the terminal 1 side of the slide switch are connected to the human body contact conductive material 211, the second contacts 69 and the movable electrodes 252 are further connected, electrodes 5 corresponding to each switch slid to the terminal 4 side of the slide switch are connected to the human body contact conductive material 212. Thus, the electrodes 5 are detected by the touch panel 31, and the third conductive pattern 83 can be generated.
When a smartphone is used as the code recognition apparatus 3, it is preferable that the maximum number of switches for sliding to the terminal 1 side and the terminal 4 side of the slide switch is 5 or less. This is to deal with code recognition apparatuses 3 when they are smartphones where the number of coordinates simultaneously detectable by the touch panel 31 is set to a maximum of five locations and error processing control is performed if this number is exceeded.
As described above, for the code generation apparatus 106 of the sixth embodiment, by enabling the selective generation of the first, second and third conductive patterns 81, 82, and 83, by setting the setting unit 7 so that three output pathways can be switched over with a single switch, and dividing push button switches 641 and 642 of the operation unit 6 and the human body contact conductive materials 211 and 212 into two sets, three types of pattern codes can be generated with a single code generation apparatus 106 and a single code generation apparatus can be used for three types of applications in accordance with the customer's usage. Thus, convenience for the customer can be further improved.
Also, needless to say that the number of pattern codes can be greatly increased by the switching of the first, second, and third conductive patterns 81, 82, and 83, as in the case of the code generation apparatus 101 of the first embodiment. Since the code pattern setting can be changed after the product is completed, the manufacturing costs for changing the pattern code can be reduced, the TAT for making changes can be shortened, and convenience for the customer can be improved.
The method of generating three types of pattern codes with a single code generation apparatus 106 as in the present embodiment in which the setting unit 7 is used for a setting so that the three output pathways can be switched with a single switch, and the switches of the operation unit 6 and the human body contact conductive material divided into two sets can be applied to the other embodiments such as the first, second, third, fourth, and fifth embodiments and the like.
In addition, descriptions of parts other than the setting unit 7 that are not significantly different from those of the code generation apparatus of the first embodiment are omitted.
As shown in
As shown in
Still further, the human body contact conductive material 21 may be arranged at a position where it is not touched simply by holding the stamp by the hand, and may be made so that it is touched only when a person has the will to do so.
As shown in
The selection by the setting unit 7 of the electrodes 5 to be detected by the touch panel 31 is performed by slide switches 75 provided on the first circuit board 41. Each electrode 5 is connected to one terminal of each slide switch 75, which is a code switch provided on the second circuit board 61, by a conductive wire or a conductor, and the other terminals are all connected by a common connection line 65 on the second circuit board 61, and are connected to the human body contact conductive material 21 of the housing 2 through contacts 66 so as to be separable.
Next, switching by the operation unit 6 is performed by an operation of selectively touching the human body contact conductive materials 211 and 212 with a human hand. When the code generation apparatus 107 is placed on the touch panel 31 while touching the human body contact conductive material 21, for example, with the hand, only the electrodes 5 corresponding to each switch that is slid to the terminal 1 side of the slide switch 75 and turned ON are connected with human body contact conductive material 21 and detected by the touch panel 31, and a first conductive pattern 81 can be generated.
Furthermore, when the human body contact conductive material 211 is touched by the hand from that state, the corresponding electrodes 55 are connected to the human body contact conductive material 211 and are additionally detected by the touch panel 31, and the second conductive pattern 82 can be generated. Furthermore, when the human body contact conductive material 212 is touched by the hand from the state where the human body contact conductive material 211 is being touched by the hand, the corresponding electrodes 56 are connected to the human body contact conductive material 212 and are additionally detected by the touch panel 31, and the third conductive pattern 83 can be generated.
Still further, when the human body contact conductive material 211 and the human body contact conductive material 212 are touched together by the hand from a state where the human body contact conductive material 21 is touched by the hand, the corresponding electrodes 55 and electrodes 56 are respectively connected to the human body contact conductive material 211 and the human body contact conductive material 212, and are additionally detected by the touch panel 31, and thus the fourth conductive pattern 84 can be generated.
The order in which the first, second, third, and fourth conductive patterns 81, 82, 83, and 84 are generated is not limited, and for example, when the code generation apparatus 107 is placed on a touch panel 31, and the human body contact conductive materials 21, 211, 212 are all touched by the hand, the fourth conductive pattern 84 can be generated from the beginning upon stamp placement on the touch panel 31.
As for the code generation apparatus 107a, the human body contact conductive material 21 is disposed on the outer periphery of the human body contact conductive materials 211, 212, so as to surround the human body contact conductive materials 211, 212. As a result, the human body contact conductive material 21 is simultaneously touched by an operation of selectively touching the human body contact conductive material 211 or 212 with a human hand.
For example, when the code generation apparatus 107a is placed on a touch panel 31 and a human body contact conductive material 211 is touched by the hand, since the human body contact conductive material 21 is also touched simultaneously, an electrode 52 corresponding to the switch and electrodes 55 corresponding to the human body contact conductive material 211 are detected by the touch panel 31, and the first conductive pattern 81 as shown in
As a result, there is no need to keep in mind the need to touch two electrodes at distant positions, and since the human body contact conductive materials 21 and 211 or 21 and 212 can be easily touched with one finger, the switching operation of two kinds of conductive patterns can be performed easily.
In addition, as shown in
The reason why the dispersed parasitic capacitance is maintained using the wiring 650 is to prevent the occurrence of misdetections due to localization of capacitance with the touch panel 31 enough to correspond to the capacitance of an electrode.
As a result, as for the code generation apparatus 107 of the seventh embodiment, by enabling the selective generation of the first, second, third, and fourth conductive patterns 81, 82, 83, and 84, by setting the setting unit 7 so as to make it changeable with a simple slide switch, and dividing the human body contact conductive materials 21, 211, and 212 into three systems for use in the place of the push button switch of the operation unit 6, it is possible to generate four types of pattern codes with a single code generation apparatus 107. Not only is the manufacturing cost greatly reduced by greatly reducing the number of parts of the apparatus, but also a single code generation apparatus can be used for four types of applications according to the customer's usage, and thus convenience for the customer can be improved.
Furthermore, by providing the additional wiring 650 to the common connection line 65, it is possible to have the touch panel 31 detect the first conductive pattern only by bringing the housing 2 into contact with the touch panel 31, and thus it is possible to properly generate a code pattern and reduce misdetections regardless of how a customer holds it when using a stamp.
Needless to say, the number of pattern codes can be greatly increased by switchover with switches of the first conductive pattern 81 as in the case of the code generation apparatus 101 of the first embodiment. Since the code pattern setting can be changed after the product is completed, the manufacturing cost for changing the pattern code can be reduced, the TAT for making changes can be shortened, and convenience for the customer can be improved.
The dividing of human body contact conductive material used into multiple systems, and selective touching of the human body contact conductive materials to enable the selective generation of a plurality of conductive patterns, the addition of wiring 650 to the common connection line 65 to enable touch panel 31 to detect the first conductive pattern just by bringing the housing 2 into contact with the touch panel 31, and the like in this embodiment can also be applied to the other embodiments such as the first, second, third, fourth, and fifth embodiments, and the like.
In addition, descriptions of parts other than the setting unit 7 and the operation unit 6 that are not significantly different from those of the code generation apparatus of the first embodiment are omitted.
As shown in
As shown in
Furthermore, the external form is not limited to a square shape, and any specification may be adopted as long as the stamp can be placed on a touch panel and the plurality of electrodes 5 can be evenly brought into contact with the surface of the touch panel.
As shown in
The operation unit 6 uses a method in which the conductive pattern is switched by a rotation operation of a handle unit 222 which is a rotation axis of a rotation switch 601.
The handle unit 222 is provided with a recess 221, and setting display units 224 that indicates the position of the switching setting of the rotation switch 601 is formed on the upper surface of the lower part of the housing 223. The setting display units 224 are formed by providing bulging portions at the center of each side of the rectangular upper surface of the lower part of the housing 223 and displaying setting numbers on the surface of the bulging portions.
A rotation switch 601 can selectively switchover the first, second, third, and fourth conductive patterns 81, 82, 83, and 84 which are generated when a stamp is brought into contact with the touch panel 31 by matching the positions of the recess 221 and the setting display units 224 by a rotation operation of the handle unit 222.
What is displayed on the setting display units 224 need not be a number as long as correspondence with the setting of the rotary switch 601 is apparent, and may be a symbol or a graphic. The symbol or graphic may be a symbol or a graphic corresponding to processing performed by the code recognition apparatus 3 made by the pattern code of a conductive pattern generated by the code generation apparatus 108.
Next, the setting unit 7 adopts a setting method using the solder joint 74 employed in the first embodiment. Among second circuit board electrode terminals 62 and pattern setting terminals 73 provided on the bottom surface of the second circuit board 61 connected from electrodes 5 other than electrodes 55, 56, 57 among electrodes 5 of the first circuit board 41, only the terminals corresponding to the electrodes detected by the touch panel in the first conductive pattern 81 are connected by the solder joint 74. The solder joint 74 corresponds to ae function of turning ON the first code switch 71 of the setting unit 7. The pattern setting terminals 73 are connected to a common connection line 65 on the upper surface of the first circuit board 61 through through holes, and are connected to four first contacts 67 of the rotary switch 601.
The electrodes 55, 56, and 57 of the first circuit board 41 are connected to first contacts 671, 672, and 673, respectively, of the rotary switch 601 on the upper surface of the second circuit board 61 through holes and wiring on the circuit board, and corresponding second circuit board electrode terminals 621, 622, and 623 provided on the bottom surface of the second circuit board 61 and pattern setting terminals 731, 732, and 733 are connected by the wiring pattern of the circuit board.
In addition, the mechanism of the rotary switch 601 which is an operation unit 6 is shown in
In addition, the movable electrodes 25 are connected to a human body contact conductive material 21 formed of the conductive material of the handle unit 222 in a state where the movable electrodes 25 can be separated from the lower part of the housing 223 via contacts 66.
The first conductive pattern 81 can be generated by connecting electrodes 5 connected to first contacts 62 and pattern setting terminals 73 connected with solder joints 74 on the bottom surface of the second circuit board 61 to a human body contact conductive material 21 via first contacts 67 and movable electrodes 25 on the upper surface of the second circuit board 61 by settings of the rotary switch 601 among the electrodes 5 of the first circuit board 41, by aligning the recess 221 of the handle unit 222 of
The second conductive pattern 82 can be generated by connecting electrodes 56 of the first circuit board 41 to a human body contact conductive material 21 via first contacts 672 and movable electrodes 25 on the upper surface of the second circuit board 61 by settings of the rotary switch 601 via first contacts 622 and pattern setting terminals 732 on the bottom surface of the second circuit board 61, in the place of electrodes 55 of the first circuit board among circuit paths for generating the first conductive pattern 81, by aligning the recess 221 of the handle unit 222 of
The third conductive pattern 83 can be generated by connecting electrodes 57 of the first circuit board 41 to a human body contact conductive material 21 via first contacts 673 and movable electrodes 25 on the upper surface of the second circuit board 61 by settings of the rotary switch 601 via first contacts 623 and pattern setting terminals 733 on the bottom surface of the second circuit board 61, in the place of electrodes 55 of the first circuit board among circuit paths for generating the first conductive pattern 81, by aligning the recess 221 of the handle unit 222 of
The fourth conductive pattern 83 can be generated by having a touch panel 31 detect only electrodes 5 connected with solder joints 74 among circuit paths for generating the first conductive pattern 81, since there are no connections to the A-side contact by the settings of the rotary switch 601 by aligning the recess 221 of the handle unit 222 of
As a result, four types of conductive patterns can be generated just by a simple operation of switching the rotary switch 601 with a single code generation apparatus 108.
In addition, since the fourth conductive pattern 84 has one less electrode detected by the touch panel 31 than the other first, second, and third conductive patterns 81, 82, and 83, it cannot be used if the above described method of error determination by checking the number of detected electrodes of a code pattern by a code recognition apparatus 3 is used. In order to deal with this case, a stopper having a detachable structure that prevents the handle 222 of the rotation switch 601 from being rotated to the position of setting “4” may be provided in the housing 2 or the rotation switch 601.
Thus, with the code generation apparatus 108 according to the eighth embodiment, by enabling the selective generation of four types of conductive patterns by a simple operation of turning the handle 222 according to the four switchover settings of the rotary switch 601 of the operation unit 6, it is possible to easily generate four types of pattern codes with a single code generation apparatus 106, and thus, a single code generation apparatus can be used for four types of applications according to the customer's usage, and convenience for the customer can be improved.
Needless to say, the number of pattern codes can be greatly increased by the switching of the switch of the first conductive patterns 81 as in the case of the code generation apparatus 101 of the first embodiment. Since the code pattern setting can be changed after the product is completed, the manufacturing cost for changing the pattern code can be reduced, the TAT for making changes can be shortened, and convenience for the customer can be improved.
The methods of selectively generated a large number of conductive patterns by a simple operation of turning the handle 222 using switchover settings of a rotary switch described in this embodiment can also be applied to other embodiments such as the first, second, third, fourth, and fifth embodiments and the like.
As shown in
Since the pattern generation mechanism and the like of the second, third, and fourth conductive patterns 82, 83, and 84 are the same as those in the seventh embodiment, descriptions thereof are omitted.
As shown in
A notch 293 is provided asymmetrically with respect to the center of the plane in the horizontal direction at an end side of the code setting card 29. The notch 293 is for avoiding a connection structure of electrodes 55 and 56 for generating the second, third and fourth conductive patterns 82, 83 and 84, and has the function of detecting the insertion end point when a card is inserted and of preventing a card from being inserted to the end when the wrong side is inserted.
On the rear end side of the code setting card 29, a small hole is provided as an index mark 294 at the left end of the upper plane. Also with the index mark 294, it is possible to prevent the wrong side from being inserted by mistake. The index mark 294 may be any mark other than a hole as long as it serves as a mark for identifying a position such as a recess, convex, ink, or the like. A code setting card 29 has a function of selectively switching the connection between electrodes 5 to be detected by a touch panel 31 and electrodes 5 not to be detected. Setting holes 291 are opened in areas on the plane of the code setting card 29 to correspond to the positions of electrodes 5 on the bottom surface 4 of the housing 2 to be detected by a touch panel when a code setting card 29 is properly inserted into an insertion hole 28 of the housing 2. Furthermore, areas 292 corresponding to electrodes 5 that are not to be detected by the touch panel 31 are not opened and maintain the state of the card surface.
As shown in
The first conductive pattern 81 is set by the connection of only electrodes among electrodes 5 of the first circuit board 41 at positions where setting holes 291 of a code setting card 29 are opened connected to first contacts 67 on the upper surface of the second circuit board 61 connected to electrodes 5 of the first circuit board 41 and second contacts 69 on the bottom surface of the third circuit board via the setting holes 291 upon inserting a code setting card 29 into an insertion hole 28, and by the connection of second contacts 69 to human body contact conductive materials 21 via common wiring 65 and contact 66.
has.
Furthermore, the second contacts 69 are made elastic with a spring pin connector, conductive rubber, contact spring or the like so that a good connection state can be maintained even with insertion-removal of a code setting card 29. Furthermore, it is preferable to provide a taper shape that widens toward the side facing the second contacts 69 with respect to the cross-sectional shape of the setting holes 291 of a code setting card 29 in the insertion-removal direction.
Thus, a first conductive pattern 81 can be generated by having a touch panel 31 detect only electrodes 5, among electrodes 5 of the first circuit board 41 with corresponding setting holes 291 opened on the code setting card 29, selectively connected to human body contact conductive materials 21, for example, by bringing the code generation apparatus 109 into contact with the touch panel 31 with a human hand.
As a result, with a code generation apparatus 109 according to the ninth embodiment, by employing a method of inserting a code setting card 29 having setting holes 291 into an insertion hole 28 of the housing 2, changing settings can be done by simply exchanging the code setting card of the setting unit 7. This enables a customer to easily change the pattern code in accordance with the usage situation, and therefore convenience for the customer can be further improved. Needless to say, the number of pattern codes can be greatly increased by switchover with switches of the first conductive pattern 81 as in the case of a code generation apparatus 101 of the first embodiment. Since the code pattern setting can be changed after the product is completed, the manufacturing cost for changing the pattern code can be reduced, the TAT for making changes can be shortened, and convenience for the customer can be improved.
The method of using the code setting card 29 for the setting unit 7 used in this embodiment can also be applied to the other embodiments such as the first, second, third, fourth, fifth, sixth, seventh, and eighth embodiments, and the like.
As shown in
As shown in
A second circuit board 61 is detachably fixed to the housing 2 in an upper section of the housing 2, and a common connection line 65 is provided on the bottom surface of the second circuit board 61 in correspondence with the position of the electrodes 5 of the first circuit board 41.
The common connection line 65 is screwed to the handle unit 222 provided on the upper portion of the housing 2 with a conductive screw at the center of the circuit board, and is connected to the human body contact conductive material 21 by connection with a conductive material part of which at least a part is formed of conductive material.
If the second circuit board 61 is separated from the touch panel 31 to an extent that the parasitic capacitance between the common connection line 65 and the touch panel 31 is small enough not to affect electrode detection by the touch panel 31, the common connection line 65 may have a configuration in which the whole bottom surface of the circuit board is a conductor. In that case, it is not necessary to create a wiring pattern for the second circuit board 65, and the manufacturing cost can be reduced.
When the bottom surface 4 of the housing 2 is placed on the touch panel 31 with contact, in order to accommodate both a case where electrodes 5 are disposed in positions where there is no spacing 411 between the electrodes 5 and the touch panel 31 so that electrodes 5 provided on the bottom surface of the first circuit board 41 movable in the vertical direction are in contact with the touch panel 31, and a case where electrodes 5 are disposed in positions where there is spacing 411 between the electrodes 5 and the touch panel 31 so that the electrodes 5 are not in contact with the touch panel 31, that is, the electrodes 5 are located farthest from the touch panel 31, to prevent the opposite surfaces of the electrode columns 57, 58, 59 forming the electrodes 5 from separating from the common connection line 65, they are connected with conductive springs 571 that can be vertically expanded or contracted, conductive rubber 581 or the like.
The setting unit 7 has a structure in which the first circuit board 41 and the electrode columns 57, 58, and 59 inserted in the insertion holes 412 of the first circuit board 41 are movable in the vertical direction, and a conductive pattern is set by changing the vertical position of the electrodes 5.
The setting of a conductive pattern by changing the vertical position of the electrode columns 57 is performed in a state where the second circuit board 61 in an upper section of the housing 2 is removed.
Depending on how deep the screw of the electrode column 58 is screwed into the insertion hole 412, the vertical position of the electrode column 58 can be changed.
The setting of a conductive pattern by changing the vertical position of the electrode columns 58 is performed in a state where the second circuit board 61 in an upper section of the housing 2 is removed.
Depending on how deep the screw of the electrode column 59 is screwed into the insertion hole 412, the vertical position of the electrode column 59 can be changed.
The setting of a conductive pattern by changing the vertical position of the electrode column 59 in a state where the sheet 410 on the bottom surface of the first circuit board 41 is removed. Thus, when it is desired to prevent the setting from being changed easily, as shown in
For the first circuit board 41 having a structure in which spacing 411 is provided only at the positions of the electrodes 5, the bottom surface of the first circuit board 41 serves as the bottom surface 4 of the code generation apparatus 110C, and it becomes easy to even the heights of the electrodes 5 for the touch panel 31 to detect, and the flatness of the bottom surface 4 can be easily secured. This structure of the first circuit board can also be applied to the structures of
With these structures, the electrodes 5 and the human body contact conductive material 21 are connected, for example, when a person holds the handle 222 by the hand and has the code generation apparatus make contact with the touch panel 31. However, capacitance necessary for detection by the touch panel 31 can be generated, the code generation apparatus can be detected by the touch panel 31, and a conductive pattern can be generated only with electrodes 5 of which there is no spacing 411 between electrodes 5 and the touch panel 31.
As a result, with a code generation apparatus 110 according to the tenth embodiment, by adopting specifications in which the setting unit 7 has a structure in which the electrodes 5 provided on the first circuit board 41 are movable in the vertical direction with respect to the bottom surface 4 and conductive patterns can be generated selectively, the number of parts can be greatly reduced and thus manufacturing costs can be reduced.
Needless to say, similarly to the code generation apparatus 101 of the first embodiment, the number of pattern codes can be greatly increased by switching the vertical positions of the electrodes 5. Since the code pattern setting can be changed after the product is completed, the manufacturing cost for changing the pattern code can be reduced, the TAT for making changes can be shortened, and convenience for the customer can be improved.
While various embodiments using the code generation apparatus have been described above, the present invention is not limited to these embodiments, and the code generation apparatus can be used for various other purposes. Furthermore, the embodiments in the present specification and drawings can be combined in various ways.
Furthermore, in the embodiments in the present specification and drawings, the code generation apparatus is described as being used by bringing it into contact with the touch panel 31. However, the electrodes of the code generation apparatus are not limited to being in contact with the touch panel, and it is sufficient to have the apparatus over the code detecting area as long as capacitance change is in a range enough for detection of touching by the touch panel, and the functions of the present invention can also be realized with a touch panel having a hovering function.
Also, the descriptions of the parts other than the electrode and the conductive pattern creation method that are not significantly different from those of code generation apparatuses of the first embodiment and other embodiments are omitted.
As shown in
As shown in
The thickness and the material of the conductive pattern printing sheet 400 are such that when the electrode 5 makes contact with the touch panel 31, the electrode 5 is detected by the touch panel through the base material of the sheet. The thickness and material are not limited to the above-mentioned thickness and material, and any thickness and material may be used as long as durability that can withstand the stamp operation of repeatedly pressing a touch panel can be secured. For example, a polypropylene resin sheet or high-quality paper for photographic printing with PP coating is sufficient. Furthermore, the method of bonding is not limited to a method of using double-sided tape, and as long as there is no positional deviation of the bonding surface and the bonding can easily be removed when it is to be removed, a method of applying adhesive glue or the like is sufficient.
The conductive ink used for printing a conductive pattern printed sheet 400 may be any ink as long as it has conductivity, such as silver paste ink, silver salt ink, silver nano ink, carbon ink, or the like, The minimum wiring width for wiring in a conductive pattern is preferably 0.8 mm to 1.0 mm for carbon ink in view of the percentage of defective products due to parasitic capacitance of the conductive pattern, wiring time constants, necessity of ink layer flattening, wiring pattern disconnection, increase in resistance or the like, and when the percentage of defective products due to wiring pattern disconnection, increase in resistance, or the like is within an allowable range, a width of 0.6 mm to 1.0 mm is more preferable. In the case of silver paste ink or the like containing metal, it is preferably to have a width of 0.2 mm to 0.3 mm, and if the percentage of defective products due to wiring pattern disconnection, increase in resistance, or the like is within an allowable range, a width of 0.1 mm to 0.2 mm is more preferable.
In the case of a conductive pattern printed sheet 400 made of PET resin having a thickness of 0.188 mm, from the viewpoint of parasitic wiring capacity, it is sufficient that the minimum wiring width is 0.8 mm or less by adopting a wiring method described later. The wiring resistance is preferably about 100 Ω/mm, and may be 1 KΩ/mm or less. Furthermore, The thicknesses of the electrodes 5 formed by printing and the ink layer of the wiring is preferably as thin as possible, and is preferably 10 μm or less, and 20 μm or less which does not require planarization is sufficient.
Guiding grooves 205 that are shallower than the thickness of a conductive pattern printed sheet 400 including the double-sided adhesive tape are provided on the bottom surface 4 and the side surface of the lower housing 201. By attaching the conductive pattern printed sheet 400 to the lower housing 201 using the guide groove 205, it is possible to improve work efficiency for attaching while ensuring the attachment position accuracy. Furthermore, by making the depth of the guide groove 205 shallower than the thickness of a conductive pattern printed sheet 400, the conductive pattern printed sheet 400 can be brought into tight contact with the touch panel 31 when being brought into contact with the touch panel 31.
The design can also be improved by printing a graphic such as a product logo on the outer surface of a conductive pattern printed sheet 400 that makes contact with a touch panel 31. Furthermore, since the conductive pattern printed sheet 400 is exposed, it is possible to attach a protective sheet such as a thin silicon sheet of about 50 μm that does not interfere with detection of electrodes by a touch panel 31 for the purpose of protecting the sheet and the outer printed surface, and preventing slippage (displacement) when making contact with a touch panel 31. When attaching a protective sheet, it is preferable to reduce the sheet thickness of the conductive pattern printed sheet 400 to about 0.125 mm in consideration of the thickness of the protective sheet.
A circuit board 611 is fitted on the upper surface portion of the lower housing 201. As shown in
Also, a circuit board sheet presser 202 is provided with a planar fixing unit that can simultaneously fix a circuit board 611 and a conductive pattern printed sheet 400 on the outer periphery of the surface of the lower housing 201, and an outer frame portion that covers the side surface of the lower housing 201. By providing an outer frame portion, the side surface portion of the conductive pattern printed sheet 400 is protected, and since almost the entire side surface of the code generation apparatus 111 is covered, the design of the code generation apparatus 111 can be improved, by applying colors or patterns to the outer surface of the outer frame portion. Furthermore, by extending the side surface of the upper housing 203 to the vicinity of the bottom surface 4 so as to cover the side surface of a code generation apparatus 111, the circuit board sheet presser 202 can be a simple flat plate without the outer frame portion.
A circuit board 611 has openings at four locations on the inner side corresponding to the corners of the rectangle, and by inserting substantially column shaped supporting columns 206 protruding from the lower housing 201, positioning of with the lower housing 201 is determined. In addition, the circuit board 611 has an opening at the center of the circuit board, and a lower side movable contact unit 251 is inserted from the back surface to the front surface retaining slidably and fixed by sandwiching the circuit board 611 with an upper side movable contact unit 252.
A thin wiring pattern is used to connect board connection terminals 612 provided on the outer periphery of the front surface of a circuit board 611 to the upper side fixed contacts 613 provided around the front surface of the central opening with the shortest distance. In addition, as shown in
There are three types of connection specifications from the circuit board connection terminals 612 to the fixed contacts 613 and 614 near the central opening. (a) One in which lower side fixed contacts 614 are provided only on the back surface, (b) one in which upper side fixed contacts 613 are provided only on the front surface of a circuit board 611, and (c) one in which fixed contacts 613 and 614 are provided on both the front and back surfaces.
As for the three types of connection specifications, at least one set is provided on each side of the circuit board 611, the sufficient total for each side is 5 sets or more of (a) and (b), and 4 sets of (c). This is because there is a limit in the number of multi-touches that can be detected simultaneously by a touch panel 31 of a smartphone such as an iPhone (registered trademark), and to ensure an ease of wiring between electrodes 5 of a conductive pattern printed sheet 400 and circuit board connection terminals 612. For use with tablets of the like where the number of allowed multi-touch is large or there is no limit, the total number of necessary sets of terminals of the connection specifications for each side of the circuit board is the same number as the multi-touch number for (a) and (b), and multi-touch number minus one for (c).
The three types of connection specifications are used according to electrode detection specifications for the conductive pattern to be created. (a) is used for electrodes detected by the touch panel 31 only for the second conductive pattern, (b) is used for electrodes detected by the touch panel 31 only for the first conductive pattern, and (c) is used for electrodes detected for both the first and second conductive patterns.
As shown in
The upper side movable contact unit 252 has a structure in which a step portion 255 is provided at the top of a columnar body with a substantially rectangular shape in a plan view, a concave is provided in the center of the columnar body, and the lower side movable contact unit 251 is fitted in, and the whole unit has conductivity. At positions facing the upper side fixed contacts 613 provided near the central opening of the front surface of the circuit board 611 of the step portion 255, a movable contact 256 made of conductive rubber having elasticity is provided to absorb the contact interval variations of the portion where the upper side fixed contacts 613 on the circuit board 611 and the upper side movable contact unit 252 make contact and enables all of the contacts to have contact conduction.
Furthermore, a movable contact 256 is not limited to conductive rubber, as with the lower side movable contact unit 251.
The upper side movable contact unit 252 is provided with a latch structure at the upper portion, and is fitted and fixed to the upper housing 203. The upper housing 203 is provided with a cylindrical opening through which a supporting column 206 is inserted with maintenance of slidability at a position corresponding to the supporting column 206 protruding from the lower housing 201. At the bottom of the cylindrical opening, there is a step where the opening diameter is reduced, and a spring is inserted into the supporting column 206, and in a state sandwiched between the lower housing 201 and the upper housing 203, a screw with a brim is fixed to the supporting column 206 which is inserted in the opening from above the upper housing 203. Thus, the upper housing 203 and the lower housing 201 are fixed maintaining slidably, and a contact driving mechanism for a conductive pattern switchover push button switch of a code recognition apparatus 111 is formed. The pairs of a lower side fixed contact 614 and a movable contact 254, and the pairs of an upper side fixed contact 613 and a movable contact 256 are set with spacing so that both of the contacts of the pairs are not in contact simultaneously at the time of a switching operation, and thus is of a non-shorting type switching method. This is to avoid being subject to limits on the number of multi-touches that can be simultaneously detected set in a touch panel 31 of a smartphone such as an iPhone (registered trademark). The structure of the lower housing 201 to the upper housing 203 corresponds to the main body 207.
A holding unit 204 is attached to the upper housing 203 with a detachable structure. The holding unit 204 includes a non-conductive lid portion that covers the upper housing 203 and enhances designability, and a conductive handle unit 222 that corresponds to a handle of a stamp. The handle unit 222 comes into contact with the upper side movable contact unit 252 and is electrically connected.
Of the electrodes 5 shown in
When the wiring width is wide, due to the parasitic capacitance generated between the wiring and a touch panel when the wiring is making contact with the touch panel 31, the touch panel 31 detects the wiring part besides the electrodes, and a phenomenon of the detected coordinates of the electrodes being deviated in the direction of the wiring occurs. For this reason, in the case of electrodes with long wiring printed in the region of the bottom surface 4, wiring is extended in the opposite direction to the original wiring as shown in
If the wiring can be printed with a width of less than 0.2 mm, the extension wiring is not necessary because the parasitic capacitance of the wiring is small.
Table 4 shows results of the evaluation of deviation of the detected coordinates compared with and without extension wiring when the evaluation sample was detected 20 times by the touch panel of a smartphone (iPhone 6) with the sample having a conductive pattern formed by arranging five 8 mm diameter electrodes made of carbon ink on a 7×6 grid lattice with a grid spacing of 7 mm on the inner surface of a 0.188 mm thick PET resin sheet and connecting with wiring with a width of 0.8 mm The sample having the extension wiring is provided with a 4 mm extension wiring having a wiring width of 0.8 mm in a direction 180° opposite to the original wiring.
Based upon the method shown in the [Overview of a pattern code decoding method] section, the electrodes 1 and 5 were used as reference electrodes so that the coordinates detected by the touch panel could be converted into coordinates of a grid arrangement with grid intervals of 7 mm, and as a result of the evaluation of the deviation of the other three electrodes with respect to the arranged grid in percentage of a grid spacing, it was confirmed that the average amount of deviation could be reduced by 10% with the extension wiring.
In the above evaluation, in regards with the wiring between electrodes 5 for forming a conductive pattern, it was confirmed that when the wiring width is 0.8 mm, the touch panel 31 detects both the electrodes 5 and the wiring due to parasitic capacitance between the touch panel and the wiring, and thus, the detected arrangement coordinates of the electrodes 5 are deviated in the direction of the wiring, and it was confirmed that the deviation could be corrected with the extension wiring. Thus, the width of the wiring between the electrodes 5 is preferably 0.8 mm or less, and more preferably 0.2 mm or less, within a range of allowable wiring width for conductive ink printing (wiring resistance does not increase).
As shown in
The first conductive pattern 81 is formed by connecting sheet connection terminals 404 connected from electrodes 5 (511, 513) of the conductive pattern printed sheet 400 and circuit board connection terminals 612(a) and 612(c) of the circuit board 611. The second conductive pattern 82 is formed by connecting sheet connection terminals 404 connected from electrodes 5 (512, 513) of the conductive pattern printed sheet 400 and circuit board connection terminals 612(b) and 612(c) of the circuit board 611.
For the first conductive pattern 81, it is preferable to have at least three electrodes 5 so that the orientation of a code generation apparatus 111 placed on a touch panel 31 can be specified, to have the arrangement of the electrodes 5 not be rotationally symmetric, and also to have the number of electrodes 5 be five or less due to restrictions on multi-touches of smartphones.
As a result, the orientation of the code generation apparatus 111 making contact on the touch panel can be specified from the results of code decoding processing of the first conductive pattern 81. Thus, since the second conductive pattern 82 can be subjected to code decoding processing using this orientation information, a pattern in which the arrangement of the electrodes 5 is rotationally symmetric can also be used as a conductive pattern. Therefore, the number of codes for the second conductive pattern 82 can be dramatically increased.
Furthermore, since according to this specification transition from (STEP 1) to (STEP 2) can be done by pressing the push button switch and two types of codes can be generated in a time series, and thus the number of codes becomes the multiplication of the number of first conductive patterns 81 and the number of second conductive patterns 82. As a result, the number of codes that can be set by the code generation apparatus 111 increases dramatically.
The code generation apparatus 111 is of a stamp type, and is used to generate pattern codes in time series by holding the handle unit 222 by the hand, touching a human body contact electrode 21, bringing into contact with and pressing down on a touch panel 31 of a smartphone or the like which is a code recognition apparatus 3, the touch panel 31 detecting a conductive pattern formed on a pattern printed sheet 400 and further switching conductive patterns with a push button switch.
On the other hand, the code generation apparatus 112 is used in a state where the main body 207 is attached to a flat holding unit 204a and the bottom surface 4 faces the front. As shown in
In this case, with a code generation apparatus 112, it is necessary to have a touch panel 31 detect a conductive pattern formed on a conductive pattern printed sheet 400 without having a the human body contact electrode 21 being touched with a finger or by the hand and without conduction to the human body. (Human body non-conduction detection)
Also, as with a code generation apparatus 111, conductive patterns can be switched by a push button switch of the main body 207 and the pattern codes can be generated in time series.
Assembly structures of the holding unit 204 and the main body 207 of the code generation apparatus 111 are shown in
As shown in
When there is a Tap due to a finger or electrodes 5 on the surface of a touch panel 31, electrostatic capacitance is formed between Tap-TXn and between Tap-RXn, and the combined capacitance Cm′ between TXn-RXn becomes smaller than Cm. Voltage amplitudes (alternating current signals) of about several hundred KHz are sequentially applied to a large number of TXn and current. In flowing on the RXn side is measured for the large number of RXn. The capacitance change of Cm′ is measured by the change in the current value In at the intersections of TXn and RXn being Tapped and the positions (coordinates) of the Taps on the touch panel 31 are specified.
In the human body conduction detection of
As for the Tap2 electrode 5 connected to the human body via a push button switch (not shown) of the code generation apparatus 111, the human body contact electrode 21 has a coupling capacitance Cp2 with the human body, and the voltage amplitude (alternate current signal) of TX2 makes a small current flow also to the human body side via coupling capacitance Cp2. For this reason, the amount of change in current I2 of RX2 increases, and the determination threshold value for coordinate detection by the touch panel 31 is exceeded, and thus the positions of electrodes 5 can be detected.
On the other hand, in the human body non-conduction detection shown in
Considering a case where a touch panel 31 applies a voltage amplitude (alternate current signal) to TX2 at the position of Tap2 where an electrode 5 is located, with human body non-conduction detection, each electrode 5 of the other Tap1, Tap3, and Tap4 has a coupling capacitance with TXn and RXn via a common node, and the voltage amplitude (alternate current signal) of TX2 makes a small current In flow to RXn via each coupling capacitance. Furthermore, the additional capacitance Cp2′ also becomes coupling capacitance, and a small current flows to the ground.
For this reason, the amount of change in the current I2 of RX2 increases, and the determination threshold value for coordinate detection by the touch panel 31 is exceeded, and thus the positions of electrodes 5 can be detected.
In addition, it is possible to have the touch panel 31 detect the positions of all of the electrodes 5 connected to the common node, since a small current can be flowed similarly to the coupling capacitance of an electrode 5 located at a place other than the intended TXn and RXn, even if TXn and RXn are sequentially switched over on a touch panel 31 to a location of another electrode 5.
In
For this reason, with a code generation apparatus 112 of human body non-conduction detection, both the conductive pattern 81 and the conductive pattern 82 need to be conductive patterns using a plurality of electrodes 5, and more stable detection is possible by using more electrodes 5 within the number limit of multi-touches of the code recognition apparatus 3.
On the conductive pattern printed sheet 400, 1 to 5 circular electrodes 5 having a diameter of 8 mm are arranged and connected with 0.3 mm-width wiring, and furthermore, a conductive pattern in which 12.5 mm wiring for additional capacitance is wired on the outer periphery is printed with silver nano ink. Electrode capacitance (conductive pattern) is measured with an LCR meter (f=100 KHz) between the GND of a USB connector and a terminal of a conductive pattern drawn to the outside of the touch panel 31. In an electrode detection state, an application program that displays detected coordinates by the touch panel is used, and a sample of an acrylic plate with a conductive pattern printed sheet 400 attached is placed on a touch panel 31 with an orientation as shown in the figure, and the number of electrodes detected upon rotating about 15 degrees was confirmed with 10 attempts.
Also, it was found that the wiring of 12.5 cm with 0.3 mm width could add a capacitance of 5.4 pF, and the detection performance could be slightly improved compared with when the wiring is not used. The capacitance per electrode is 2.6 pF on the average, and there are deviations depending on the electrodes (the slope of the graph is not uniform) because also included is inter-electrode wiring capacitance.
These evaluation results indicate that, for a code generation apparatus 112 with human body non-conduction detection, when the number of electrodes and additional capacitance is at the level of this evaluation sample, it is necessary to set requirements on the position and direction when the touch panel 31 is brought into contact with the bottom surface 4 of the code generation apparatus 112, and furthermore for conductive patterns, to limit the number of electrodes that can align in the vertical direction or the horizontal direction on the touch panel surface when the electrodes 5 are brought into contact. In addition, the present provision is unnecessary if the conductive pattern can be detected for any electrode arrangement by further reducing the thickness of the conductive pattern printed sheet 400, increase the capacitance of the electrodes 5, and improving detection performance by increasing the capacitance of the node to which the electrodes are connected by additional wiring or the like.
As shown in
Furthermore, instead of a conductive sheet 211 for additional capacitance, a conductive pattern connected with a movable electrode unit may be formed in a pattern free area without any wiring or contacts on the front and back surfaces of the circuit board 611 shown in
Still further, in an area of a conductive pattern printed sheet 400 as shown in
The capacitance was measured between the GND of the USB connector and the copper sheet with an LCR meter (f=100 KHz).
These evaluation results indicate that, in order to add capacitance to a conductive pattern of a code generation apparatus 112, it is desirable to add capacitance in the order of the blank part of a conductive pattern printed sheet 400, the blank portion of a circuit board 611, and the conductive sheet 211 for additional capacitance.
The code generation apparatus 112a is obtained by changing the holding unit 204a of the code generation apparatus 112 with human body non-conduction detection to human body conduction detection. There is no change from the code generation apparatus 112 except for the holding unit 204a and the method of use.
As shown in
Although not shown, as in the case of the holding unit 204a, by fitting the fitting groove 210 provided in the upper housing 203 of the main body portion 207 and the fitting protrusion 209 on the attachment surface of the holding unit 204b together and rotating, the holding unit 204b and main body 207 are fixed together, and the holding unit 204b is crimped and electrically connected to the upper movable contact unit 252 exposed in the upper housing 203 when it is fixed to the main body 207.
Thus, the holding unit 204b becomes a human body contact electrode 21, and the code generation apparatus can be regarded as a code generation apparatus of a human body conduction detection system.
Furthermore,
The push button switch mechanism of the code generation apparatus 112a with human body conduction detection is eliminated in the code generation apparatus 113, with the aim of reducing weight and cost.
As shown in
A conductive pattern printed sheet 401 that defines the shape of a code generation apparatus 113 formed with a size where a short side is shorter than the short side of a touch panel 31 of a smartphone and a long side that can secure a length long enough on the outside of the smartphone so that a human finger can further touch it while holding the short side of the smartphone by the hand, and a contact area 40 is provided on the right side in the long side direction, a holding area 50 is provided on the lower side, and ID electrodes 111D, which are the first electrodes, are arranged with a circular shape with a diameter of about 8 mm, and adjacent ID electrodes 111D are connected together in a single stroke with single straight line wiring so that the distance is the shortest. Furthermore, the ID electrode 111D at the left end is connected to a first indicator electrode 51 provided in the holding area 50. Moreover, in the contact area 40, three information electrodes 111E, which are second electrodes having a circular shape with a diameter of about 9 mm, and each is connected independently to one each of the three second indicator electrodes 52 in the holding area 50 so that the distance is the shortest with single straight line wiring.
Four ID electrodes 111D and three information electrodes 111E are arranged in the contact area 40, and conductive patterns 85 are formed by combining the four ID electrodes 111D and one information electrode 111E to form unique pattern codes. Therefore, with a card 110B, three types of conductive patterns 85 corresponding to the information electrodes 111E can be created.
Three sets of the first and second indicator electrodes 51 and 52 are provided corresponding to the information electrodes 111E, and the three first indicator electrodes 51 are all connected by wiring.
The first indicator electrodes 51 are formed so as to surround the periphery of the second indicator electrodes 52, and the spacing 53 between the first indicator electrode 51 and the second indicator electrode 52 must be narrow enough so that when a finger is placed, both electrodes are simultaneously touched with the finger without failure, and also to prevent the coupling capacitance between a first indicator electrode and a second indicator electrode from becoming large, the spacing is set to about 1.5 mm. Furthermore, the spacing between adjacent second indicator electrodes 52 is set at a predetermined distance so that when a finger is placed, they are not touched simultaneously with the finger.
Surface 405 opposite to the surface on which the conductive pattern of the conductive pattern printed sheet 401 is printed is a graphic printing surface 405 processed so that graphics can be printed on the card. The graphic printing surface 405 is subjected to printing protection processing by PP lamination or the like for protecting the printing layer after printing, as necessary.
As shown in
Furthermore, since the two remaining information electrodes 111E connected to the second indicator electrode without a finger on them do not generate capacitance, they do not have coupling capacitance with the human body, and the electrodes are not detected even if a voltage amplitude (alternate current signal) of TXn of the touch panel 201 gets generated.
Thus, by changing the indicator electrode on which a finger is placed with respect to the positions of the three indicator electrodes 51 and 52, three types of conductive patterns 85 in which only the coordinates of the information electrode 111E are changed can be generated.
Cushioning material 700 is adhered to the back surface of the contact area 40 of the conductive pattern printed sheet 401 with double-sided tape or adhesive glue. The cushioning material 700 is constituted of an elastic material such as a sponge having a thickness of about 10 mm, with the purpose to enable the entire contact area 40 to reliably make contact and to prevent the surface of the touch panel 31 from being damaged when a touch panel 31 of the smartphone which is a code recognition apparatus 3 is brought into contact. Furthermore, a chamfered curved surface or inclined surface is used for the boundary between the contact area 40 and the holding area 50, to prevent the sheet surface from bending with an acute angle and causing wiring between the electrodes to become disconnected when a conductive pattern printed sheet 401 is attached.
Since the code generation apparatus 113 is composed only of a conductive pattern printed sheet 401 and a cushioning material 700, it is very light and can be used by attaching the back surface with double-sided tape or adhesive glue onto a substrate 701 for attachment such as a poster made of paper for attaching to a wall.
Furthermore, the substrate 701 for attachment is required to have insulating properties so as not to affect the conductive pattern.
Although the code generation apparatus 113 is of human body conduction detection, according to specifications, an alternate current signal is conducted via coupling capacitance between a finger and an indicator electrode with a conductive pattern printed sheet 401 interposed therebetween. For this reason, in order to secure a required amount of capacitance, an indicator electrode needs to have an area according to the thickness of the base material of a conductive pattern printed sheet.
A sample on which a 0.3 mm thick PVC sheet is attached with double-sided tape to the front surface (printed surface) of a conductive pattern printed sheet 401 made of a 0.188 mm thick PET resin sheet with a conductive pattern of
The coupling capacitance was set to a relative dielectric constant of 3, and the reactance was calculated with the alternate current frequency set to 100 KHz. Also, in consideration of the usage method of the code generation apparatus 113, the indicator electrode area, the coupling capacitance, and the reactance were converted and tabulated based on coupling capacitance values only for cases where only the front surface side of the conductive pattern printed sheet 401 of the PET resin sheet was touched with a finger.
Table. 5 shows the second indicator electrode area dependency on the detection of the information electrode 111E. It is found that the detection rate decreases under conditions where the command electrode area of (C) is 20 mm2 and the reactance is 414 KΩ. For this reason, for a code generation apparatus 113 with human body contact detection by the coupling capacitance with the alternating current signal, it is necessary for the indicator electrode to have an area size to accommodate the reactance of 200 KΩ or less, and for a PET resin sheet with a thickness of 0.188 μm, an area of about 55 mm2 or more is necessary.
The specifications of a code generation apparatus 114 differ from the specifications of a code generation apparatus 111 in the states at the time of switching between the first conductive pattern 81 and the second conductive pattern 82. According to specifications, when the conductive patterns of a code generation apparatus 111 switch over, all of the electrodes 5 are once in a non-detected state, and the push button switch is that of a non-shorting type switching method, and according to specifications, when code patterns of a code generation apparatus 114 switch over, electrodes 5 detected for the first conductive pattern 81 remain in a detected state, and the push button switch is that of a shorting type switching method.
In order to make both specifications common except for the pattern of the circuit board 611, for the electrodes 5 to be detected for a first conductive pattern 81, it is necessary to connect the handle unit 222 which is a human body contact electrode 21 directly to electrodes 5 without going through contacts of the push button switch. For this reason, as shown in
In addition, as shown in
In the specifications of a code generation apparatus 114, the number of electrodes for the first conductive pattern 81 needs to be set to 4 or less. However, according to this specification, the program for controlling is not complex, since the timing of switching from the first conductive pattern 81 to the second conductive pattern 82 may be determined in the pattern code decoding process performed on the code recognition apparatus 3 side with the first conductive pattern 81 being decoded when the number of electrodes of the first conductive pattern 81 is determined, and the second conductive pattern 82 being decoded when the number of electrodes increases for the second conductive pattern 82.
In addition, descriptions of parts other than the ID switchover switch 95 and the conductive pattern switching method that are not significantly different from those of the code generation apparatuses of the eleventh embodiment and other embodiments are omitted.

As shown in
In addition to having a rectangular opening along the direction in which the switch operation unit 951 for switching codes slides, the opening 241 provided in the holding unit 204 extends in a substantially arc shape in the counterclockwise direction in regards with the center of the holding unit 204. This is because the code generation apparatus 115 is provided with a mechanism of rotating and fixing together the holding unit 204 and the upper housing 203 as shown in
Furthermore, the opening 231 provided in the upper housing 203 is large enough so that the body portion of the slide switch 95 and the upper housing 203 do not come into contact with each other when the handle 222 is pressed to switch the push button switch of the operation unit 6.
In addition, the two types of circuit specifications corresponding to

In this way, it is possible to easily change which of the first conductive pattern 81 and the second conductive pattern 82 is provided with a plurality of conductive patterns simply by changing the wiring pattern of a part of the circuit board.
Furthermore,
When the push button switch of a code generation apparatus 115 formed with a conductive pattern printed sheet 400a and a circuit board 611b of
Furthermore, the state of the first conductive pattern 81 shown in
Thus, three types of first conductive patterns 81 can be provided by switching the ID switchover switch 95.
Similarly, by pressing the push button switch of a code generation apparatus 115 formed with a conductive pattern printed sheet 400b and a circuit board 611c of
Thus, three types of second conductive patterns 82 can be provided by switching the ID switchover switch 95.
Thus, a code generation apparatus 115 can generate three types of codes with one housing. Furthermore, since the STEP for generating three types of conductive patterns can be changed simply by changing the circuit board, the number of codes that can be issued as a whole can be doubled by simply preparing two types of circuit boards.
In addition, compared with the circuit board 611 (
In the specifications of the circuit boards 611b and 611c, the electrodes 513 are wired to sheet connection terminals 404 of specifications (a) and (b) of conductive pattern printed sheets 400a and 400b so that they are connected to circuit board connection terminals 612 arranged adjacent of specifications (a) and (b). Thus, the fixed contacts 613 and 614 at the center of the circuit board can be reduced, the spacing between the fixed contacts can be increased, and the coupling parasitic capacitance between the electrodes can be reduced.
In addition, depending on the arrangement coordinates of the electrodes 5, there may be cases where circuit board connection terminals 612 of specifications (a) and (b) adjacent on one side of a conductive pattern printed sheet for electrodes 513 cannot be secured. In these cases, as electrodes 513 shown at the upper right end of the conductive pattern printed sheet 400b in
In this case, it is preferable to have the wiring as short as possible, since the largest factor for error of the coordinates of electrodes 5 detected by a touch panel is the parasitic capacitance between the wiring corresponding to the bottom surface 4 of the conductive pattern printed sheet and the touch panel.
Needless to say, the number of conductive patterns switched by the ID switchover switch 95 is not limited to three, and may be more than or less than three. For example, the slide switch may be of a SPDT type (one circuit and two contacts), and specifications may have the configuration include two electrodes 514 or 515 which are connected and enable switching between two types of conductive patterns.
In addition, the specification in which sheet connection terminals 404 of specifications (a) and (b) of a conductive pattern printed sheet are connected without providing circuit board connection terminals 612 of specification (c) dedicated to electrodes 513 on a circuit board may also be applied to code generation apparatuses 111, 112, and 114.
Furthermore, by applying an upper housing 203 and a holding unit 204 provided with openings 231 and 241 to the main body 207 of code generation apparatuses 111, 112, and 114, and changing the wiring specifications of the circuit board and the conductive pattern printed sheet, it is also possible to use the parts of the main body 207 of the code generation apparatuses 111, 112, 114, and 115 in common.
For example, the main body 207 of the code generation apparatus 111 is made of ABS resin, and partially of metal or the like. In addition, due of the structure of the push button switch, the material and density of the parts provided on the upper side of the bottom surface 4 are not uniform, and thus, the effective dielectric constant of the bottom surface 4 is not uniform. For this reason, when a conductive pattern printed sheet 400 is directly attached to the bottom surface portion of the lower housing 201, the characteristics of the parasitic capacitance generated due to the arrangement of electrodes 5 of conductive patterns and the wiring pattern between electrodes 5 and sheet connection terminals 404 change. Due to the non-uniform parasitic capacitance characteristics, the electrode coordinate detection error by the touch panel increases or decreases depending on the conductive pattern. For this reason, codes that cannot be decrypted are generated, and as a result, the number of codes that can be issued by code generation apparatuses 111 as a whole is reduced.
As shown in
By fitting a conductive pattern printed sheet 400 attached with a flat plate 406 inside the step 230 of the lower housing 201a, and attaching a side surface attaching unit 402 to the side surface of the lower housing 201a, it is possible to provide an air gap 407 having the same width as the step height of the step 231 between the concave 232 of the bottom surface 4 of the lower housing 201a and the flat plate 406 for the entire surface of the bottom surface 4 of the conductive pattern printed sheet 400.
Since the relative dielectric constant of the air which fills an air gap 407 is about 1 and the smallest, by providing the air gap 407, it is possible to suppress parasitic capacitance lower than when the conductive pattern printed sheet 400 is directly attached to the bottom surface of the lower housing 201, and in addition, position dependence of the bottom surface 4 is reduced and thus it can be made uniform. Thus, the error of electrode coordinates of a conductive pattern detected by a touch panel can be reduced. For this reason, the number of codes that can be issued by the code generation apparatuses 111 as a whole can be increased.
Furthermore, since the influence of the structure of the main body 207b including the lower housing 201a and the relative dielectric constant characteristics of the material on the electrode coordinates of a conductive pattern detected by a touch panel is reduced, restrictions on the structure of the main body 207b and the relative dielectric constant of the material can be alleviated.
Furthermore, since in the structure, the flat plate 406 on which a conductive pattern printed sheet 400 is attached is fitted inside the step 230 of the lower housing 201a, accuracy of the attaching position between the sheet and the lower housing is improved, and the ease of assembly is improved.
It is preferable to make the width of the flat portion between the steps 230-231 provided in the lower housing 201a as narrow as possible within a range in which the flat plate 406 can be fixed flatly, and the concave 232 as wide as possible so as not to have overlap with the electrodes 5 printed on the sheet 400. In addition, it has been experimentally confirmed that the effect of an air gap 407 can be obtained with a spacing of about 0.4 mm. Furthermore, the flat plate 406 is preferably made of a resin plate such as PVC having moderate tension and a low relative dielectric constant.
As shown in
Since the flat plate 406 can be thinned by supporting with supporting columns 233, the influence of the flat plate 406 on the detection of electrode coordinates of conductive patterns can be reduced, and also, the increase in the thickness of the main body portion due to the width of the air gap 407 (that is, the height of the step 231) and the thickness of the flat plate 406 (that is, the height of the step 230) can be reduced.
Moreover, the supporting column 233 may be provided as a wall connected to the outer periphery of both ends opposing the concave 232 instead of with a column shape, and also, the wall may be provided with a lattice structure or a honeycomb structure. Regardless of the material of the lower housing 201b, the supporting column or wall 233 has a relative dielectric constant higher than that of the air gap 407, and thus influence of the portion on the conductive pattern is larger than that of the air gap 407. For this reason, the it is preferable for the supporting columns or walls 233 to have small widths and wide arrangement spacings so that the area in contact with the flat plate 406 is small within a range in which the flatness of the flat plate 406 and the conductive pattern portion of the conductive pattern printed sheet 400 can be secured.
Furthermore, the step 231 and the supporting column 233 of the lower housing 201b may be eliminated from the structure, and instead, structure elements of a supporting column or wall 233 may be provided on the flat plate 406 and an air gap 407 may be provided by fitting them into the concave 232 inside the step 230 of the lower housing 201b.
Still further, a large number of columns or walls 233 may be provided to ensure flatness of the bottom, and the step 230 of the lower housing 201b may be eliminated, and by having the height from the bottom of the concave portion 232 of the column or wall 233 be equal to that of the outer periphery of the lower housing 201b, the conductive pattern printing sheet 400 may be used as it is without attaching the flat plate 406 to the bottom surface of the lower housing 201b.
As shown in
The elastic sheet used for the low dielectric constant layer 408 is a foamable rubber sheet such as a poron sponge sheet or a foamable CR (chloroprene) rubber sheet, or the like, and it preferably has weak elasticity.
The concave 232 of the flat plate 406 and the lower housing 201c, and the flat plate 406 are fixed by slightly reducing the size of the flat plate 406, and with the fitting portion with the side surface of the step 230 in a loose state, by attaching the bottom surface of the concave 232 and the surface opposite to the flat plate 406 of the low dielectric constant layer 408. As a result, since the variation in flatness of the concave 232 and the variation in the step height of the step 230 of the lower housing 201c can be absorbed by the elasticity of an elastic sheet of the low dielectric constant layer 408, it is not necessary to increase processing accuracy, and manufacturing can be facilitated.
Furthermore, in the configuration of the plate 406 and the low dielectric layer 408, the flat plate 406 and the low dielectric constant layer 408 are attached to the structure of the lower housing 201a in
Needless to say, the specifications in which a step is provided in the lower housing, and an air gap 407 or a low dielectric constant layer 408 is provided between a flat plate and a conductive pattern printed sheet can be applied to code generation apparatuses 111, 112, 114, 115, and the like.
With a code generation apparatus 1 capable of switching a conductive pattern, in order to increase the number of codes that can be issued with all of the code generation apparatuses 1 and to facilitate decoding into pattern codes, it is necessary to provide conditions for methods of electrode arrangement each for the first conductive patterns 81 of (STEP 1) and the second conductive patterns 82 of (STEP 2), and to perform a pattern coding process with considerations of the electrode arrangement conditions. An example of switchable conductive patterns and a pattern code decoding method is shown below.
With the code generation apparatus 1, according to specifications, by pressing for example a push button switch 60 of the operation unit 6, with (STEP 1) corresponding to the state before pressing and (STEP 2) corresponding to the state after pressing, by switching the connections between the plurality of electrodes 5 provided respectively for the first conductive pattern 81 and the second conductive pattern 82, and the human body contact conductive material 21 ON or OFF, two types of codes can be generated.
[Specifications for Electrode Arrangement for Conductor Patterns]
In addition, the electrodes 5 of each conductive pattern cannot be arranged at all integer coordinate points, and for the determination of restrictions on the distance between the electrodes 5 and arrangement positions, the size of the electrodes 5 and the influence on coordinate detection by touch panel 31 of the placement of a plurality of electrodes at close coordinate positions in a conductive pattern and the like are to be considered.
For example, the minimum value for the electrode to electrode distance needs to be greater than or equal to the distance at which two electrodes 5 are not detected as one electrode by the touch panel 31.
Furthermore, in particular for projected capacitive touch panels often used in smartphones, when a plurality of electrodes are arranged in parallel to the outer frame of the touch panel, since a plurality of code generation apparatus electrodes 5 are aligned on one line of transparent electrodes for coordinate detection in the touch panel, there are cases where detection by the touch panel 31 is affected. For this reason, the number of the electrodes 5 arranged on the same line in a conductive pattern may be given a limit.
For the first conductive pattern 81, it is necessary to detect at least three electrodes 5 so that the orientation in which the code generation apparatus 1 is placed on the touch panel 31 can be specified, and in consideration of the assumed limitation of the number of multi-touches for a smartphone, a maximum number of five electrodes is preferable. Therefore, in this embodiment, the four electrodes 5 are provided for the first conductive pattern 81.
However, when the method of use has the orientation of the surface making contact with the touch panel 31 of the code generation apparatus 1 fixed, or when there are no limit on the number of multi-touches, or when tablets which detect five or more, or dedicated business apparatuses are used as the code recognition apparatus 3, the minimum number and the maximum number of electrodes are not limited to the above described numbers.
As for the first conductive pattern 81, it is preferably to provide a reference electrode to facilitate code decoding. In this embodiment, all of the first conductive patterns 81 are provided with the two electrodes at the positions (0, 0) and (6, 6) of the grid coordinate system as reference electrodes, which have the longest distance in between. As a result, the length Lmax between the reference electrodes, the angle θ1 formed by the line segment connecting the reference electrodes and the X axis of the grid coordinate system can be used for code decoding. Furthermore, the reference electrode positions are not limited to the coordinates of this embodiment, as long as the distance between the reference electrodes, and the angle formed by the line segment connecting the reference electrodes and the X axis of the grid coordinate system can be specified.
For example, in this embodiment, reference electrodes can also be provided at the two points (0, 0) and (5, 6). By making the code decoding processing algorithm correspond to other reference electrode positions, a large number of conductive patterns having different code systems can be set. If conductive patterns and code decoding processing algorithms corresponding to each of a plurality of code systems are prepared, for example, a code system using the two points (0, 0) and (6, 6) of this embodiment as reference electrodes, a code system using the two points (0, 0) and (5, 6) as reference points, and a code system using two other points as reference points and so forth, even more codes can be issued for the whole system without having to change the main body of a code generation apparatus 1.
As for the second conductive pattern 82, due to switchable feature of a code generation apparatus 1, information on the electrode arrangement coordinates of both the first conductive pattern 81 in (STEP 1) and the second conductive pattern 82 in (STEP 2) can be used for decoding, and thus reference electrodes are unnecessary. Therefore, for the second conductive pattern 82, electrodes 5 can be freely arranged at the arrangement coordinates as long as restrictions on spacing between electrodes 5 and arrangements are followed.
Also, the number of arranged electrodes can be freely arranged within the range of 1 or more to the restricted number of multi-touches. Therefore, more conductive patterns can be set for the second conductive pattern 82. According to the present embodiment, code generation apparatus 1 is configured to have one to four electrodes arranged in the second conductive pattern 82.
Furthermore, for the second conductive pattern 82, due to the switchable feature of a code generation apparatus 1, it is possible to arrange electrodes 5 of the second conductive pattern 82 at the same coordinates as those of electrodes 5 arranged in the first conductive pattern 81. For example, for a code generation apparatus 1 having a configuration in which a conductive pattern printed sheet 400 is used and the code generation apparatus 1 is capable of switching conductive patterns, if the electrodes 5 of the first and second conductive patterns 81 and 82 are arranged at the same coordinates, the number of electrodes printed on the conductive pattern printed sheet 400 is smaller than the sum of the number of electrodes used in (STEP 1) and (STEP 2), and thus the arrangement of electrodes 5 of the two types of conductive patterns is facilitated, and a large number of conductive patterns can be set.
Also, although according to the present embodiment, the code generation apparatus 1 is configured so that reference electrodes are provided in the first conductive pattern 81, and the number of the electrodes 5 is three or more, so that the orientation of the code generation apparatus 1 placed on the touch panel 31 can be specified with the first conductive pattern 81, and reference electrodes are not provided in the second conductive pattern 82, it is also possible to provide reference electrodes in the second conductive pattern 82, and have the number of the electrodes 5 be three or more, so that the orientation of the code generation apparatus 1 placed on the touch panel 31 can be specified with the second conductive pattern 82, and reference electrodes are not provided in the first conductive pattern 81. If specifications of the latter configuration are also provided separately, even more codes can be issued for the whole system without having to change the main body of a code generation apparatus 1.
Still further, it is also possible to set a group of reference electrodes by combining patterns of both the first conductive pattern 81 and the second conductive pattern 82. For example, the reference electrode at the position (0, 0) can be provided in the first conductive pattern 81, and the reference electrode at the position (6, 6) can be provided in the second conductive pattern 82, and longest distance between electrodes can be set with electrodes 5 of both the first conductive pattern 81 and the second conductive pattern 82, and by using an electrode 5 other than those used as reference electrodes for the first and second conductive patterns 81 and 82, the orientation of the code generation apparatus 1 placed on the touch panel 31 can also be specified. As a result, since the number of electrodes that can be freely arranged in both the first and second conductive patterns 81 and 82 increases, even more conductive patterns can be provided, and even more codes can be issued for the whole system.
A normalized coordinate pattern code table is created by organizing coordinate values of first conductive patterns 81 and second conductive patterns 82 created upon these specifications as normalized coordinate pattern codes for (STEP1) and (STEP2).
[Pattern Code Decoding Method]
With the code generation apparatus 1 capable of switching conductive patterns, according to specifications, a first conductive pattern 81 of (STEP 1) and a second conductive pattern 82 of (STEP 2) are provided, and by pressing a push button switch 60 which is the operation unit 6, the connections between the plurality of electrodes 5 provided respectively and the human body contact conductive material 21 are switched ON or OFF, and thus two types of codes can be generated.
For this reason, it is necessary to determine whether the electrode coordinate information detected by the touch panel 31 is that of the first conductive pattern 81 of (STEP 1) or the second conductive pattern 82 of (STEP 2) as a pre-stage of general code decoding processing.
Since two types of conductive patterns are provided, electrodes 5 that are not necessary for the electrode arrangements of either the conductive patterns 81 and 82 are provided on the bottom surface 4 of the code generation apparatus 1 disconnected with human body contact conductive material 21 are present on the touch panel 31 of a smartphone which is an example of a code recognition apparatus 3.
Moreover, in the touch position detection algorithm of a touch panel 31 of a smartphone 3, in order to continuously recognize a finger touch as the same touch, there are some smartphones in which there is a control system for reducing the detection sensitivity threshold value at a touch position once detected (detection threshold hysteresis control), and for some of these smartphones in which the extent of detection threshold decrease due to hysteresis control of the threshold is set to be a large, in some cases, electrodes 5 of the first conductive pattern 81 of (STEP 1) connected to the human body contact conductive material 21 may continue to be detected by the touch panel 31 in spite of being disconnected from the human body contact conductive material 21 for the second conductive pattern 82 of (STEP 2), thus causing the problem of misrecognition of the correct code of the second conductive pattern code 82.
An example of a pattern code decoding method dealing with these two problems will be described.
The electrode arrangement specification of the conductive patterns of the present embodiment complies with the following four conditions. (1) Four electrodes 5 including two reference electrodes are used for the first conductive pattern 81. (2) One to four electrodes 5 are used for the second conductive pattern 82. (3) In the electrode arrangement of the second conductive pattern 82, electrodes are not arranged at electrode arrangement positions of the first conductive pattern 81. (4) The values of distance between the electrodes of the second conductive pattern 82 are set to be smaller than the distance of Lmax between the reference electrodes.
Next, in the state of S2, L1pmax is divided by the number of electrode arrangement grids between the reference electrodes (6 in this embodiment) to obtain the detected coordinate allowable error range length L1pm of the coordinate system on the touch panel.
In addition, when the touch panel further detects four new coordinates in the state of S2, the state becomes S3, and all of the distances between two of the four points are calculated and the longest interelectrode distance of L1pmax′ is obtained, and if the value is in the range of ±L1pm/2 with respect to the stored L1pmax, the electrode coordinates of P11 to P14 of the four points of (STEP1) are updated, and S2 is performed again.
Next, as shown in
When the predetermined transition time tt12 has passed, the state becomes S5, the coordinate values of the detected electrode coordinates of P21 to P2n at that time are compared with the stored coordinate information of P11 to P14, and leaving out only the coordinates outside the range of the concentric circle L1pm/2 of the coordinates, the number of remaining detected electrodes m and detected coordinates P21 to P2m are stored as detected coordinates after pressing (STEP2).
When the detected electrode coordinates of the second conductive pattern 82 are obtained, the state becomes S6, and the detected coordinates P11 to P14 of (STEP 1) and the number of detected electrodes m and the detected coordinates P21 to P2m of (STEP 2) are combined, sent to the decryption flow, and the pre-processing ends.
Next, when the detected coordinate information of (STEP 1) and (STEP 2) are ready, the code decoding flow is executed.
As shown in
Here, since the angle θ1 of the line segment connecting with the reference electrodes P11 and P14 with respect to the X axis of the arrangement grid coordinates is known, the rotation angle θ′ of the arrangement grid coordinate system with respect to the touch panel coordinate detection system can be obtained by subtracting θ1 from θ0. Also, similarly, since the length of the line segment connecting the reference electrodes P11 and P14 is also known, by taking the ratio with the longest line segment L1, the enlargement/reduction ratio of the arrangement grid coordinate system with respect to the touch panel coordinate detection system can be determined.
From these pieces of information, the coordinates are converted into those of the arrangement grid coordinate system for electrode arrangement by rotating the coordinate values on the touch panel by −θ′ and applying enlargement/reduction ratios with PS as the origin.
All of the detected coordinates of (STEP 1) and (STEP 2) are coordinate-converted, and whether or not the coordinate values of the respective detection points after conversion are within the range of the detected coordinate allowable error is determined by collation with coordinate values of each normalized coordinate pattern code table. If there is no match as a result of the collation, the starting point PS and the end point PE are exchanged, and the process is executed again from the state E2. (States E3 and E4 in
By specifying each ID code of (STEP1) and (STEP2) from the obtained coordinate values, specifying ID codes as those of a code generation apparatus by combining them, and executing corresponding processings, code decoding processing is completed. (States E3 and E4 in
Also, according to specifications of this embodiment, although the code generation apparatus 1 is configured so that the code can be recognized regardless of the angle of placement when the code generation apparatus 1 is brought into contact with the touch panel 31, it is possible to execute processings according to the rotation angle upon code generation apparatus 1 making contact with the touch panel 31 by using the rotation angle between the detected coordinate system of the touch panel 31 obtained in the process of the code decoding processing and the arrangement grid coordinate system. With a single code generation apparatus 1, for example, it is also possible to execute four different processings corresponding to the four states of rotation angles of 0, 90, 180, 270 degrees of the code decoding process, corresponding to each of the four sides of the substantially square bottom surface shape of the code generation apparatus 1 with respect to one side of the touch panel 31.
Furthermore, the pre-processing flow part shown in
The conductive pattern specifications and the pattern code decoding methods of the present embodiment are not limited to those described, and it is needless to say that as long as it is possible to determine whether or not pattern codes created based on the conductive pattern specifications and subjected to decoding processing match with those of the pattern code table, the code decoding processing may be performed in any manner.
Also, the descriptions of the parts other than the main body portion, the operation unit 6 and the setting unit 7 that are not significantly different from those of code generation apparatuses of other embodiments are omitted.
As shown in
On the upper side of the sheet 410, piston parts 520 forming the electrodes 5 are attached to one end portion of the connecting rods 522 with allowable rotation by pins 521.
Furthermore, shaft bearing holes 523 having a C-shaped opening on the side surface of the longer direction of the rods are provided at the other end of the connecting rod 522, and are attached to the crankshaft 524 in a detachable manner with allowable rotation.
The bottom surface 4 of the housing 2 is provided with cylinder parts 240 that have substantially the same shape as those of electrodes 5 and are provided with a cylindrically shaped opening that enable the piston parts 520 to slide in the vertical direction. The cylinder parts 240 are evenly arranged with enough spacing to disable the detection of two adjacent electrodes 5 as a single electrode even if they are in contact with the touch panel 31 at the same time.
Crankshafts 524 are provided with a shaft arm 525 that moves a piston part 520 vertically via a connecting rod 522 as the shafts rotates. The shaft arms 525 are set to have lengths long enough so that the electrodes 5 which are the bottom surfaces of the piston parts 520 are at the same vertical positions as the bottom surface 4 of the housing 2 when the piston parts 520 are at the lowest point, and the electrodes 5 rise to positions sufficiently away from the surface so they are not detected by the touch panel 31 when the piston arms 520 are at their highest points.
Furthermore, it is possible to have the crankshafts 524 not to be provided with the shaft arms 525, and the connecting rods 522 are directly attached to the shaft parts 526 of the crankshafts 524. In this case, the lengths of the connecting rods 522 are set so that the electrodes 5 which are the bottom surfaces of the piston parts 520 are at the same vertical position as the bottom surface 4 of the housing 2 regardless of the rotation of the shafts.
Both ends of the shaft part 526 of a crankshaft 524 are attached to a shaft bearing 241 inside the side surface of the housing 2 with allowable rotation, and a pinion gear 620 is fixed to the shaft part 526. Also, a rack 621 is fixed from the sliding plate 242 fixed to the handle unit 222 so as to mesh with the pinion gear 620 of the crankshaft 524, and the crankshaft 524 and the handle 222 are dynamically connected by the rack and pinion mechanism.
In the structure, sliding guide columns 243 are provided at the four corners of the housing 2, and there is sliding through the through holes provided at the end of the sliding plate 242. A spring 244 is wound around the sliding guide column 243 and is sandwiched between the bottom end portion of the sliding guide column 243 and the sliding plate 242 and is fixed to be expandable. Except when the handle 222 is pressed, the sliding plate 242 is pushed up to the upper end of the housing 2 by the spring 244.
From the handle 222 to the sliding plate 242, rack 621, pinion gear 620, crankshaft 524, shaft arm 525, connecting rod 522, pin 521, piston part 520 and electrodes 5, all are of metal, of a conductive resin, of a resin with surface plating treatment or the like, and are parts with conductivity. The handle 222 and electrodes 5 which are the human body contact conductive material 21 are electrically connected.
The setting unit 7 comprises a shaft arm 525 provided on the crankshaft 524 and a piston part 520 that can be attached and detached.
It is possible to switch the number of electrodes to be detected and arrangement coordinates for the electrodes 5 depending on whether or not the piston parts 520 which are electrodes 5 are installed in the cylinder parts 240 provided on the bottom surface 4 of the housing 2. Furthermore, it is possible to change conductive patterns before and after pressing by changing between the states of making contact and releasing contact at the pressing position of the handle 222 by the orientation of the shaft arm 525 provided on the crankshaft 524 at a position corresponding to the piston part 520 of the electrodes 5 and the positional relationship between the pinion gear 620 and the rack 621.
As shown in
By the rack and pinion mechanism and the piston mechanism, it is possible to switch between making contact and releasing contact for the electrodes 5 with respect to the touch panel 31 before and after the handle unit 222 is pressed, and thus conductive patterns can be switched.
Furthermore, since electrodes 5 that are not electrically connected to the human body contact conductive material 21 when conductive patterns are switched are physically separated from the touch panel 31, the capacitance of the touch panel 31 does not change, and thus more stable code recognition is possible.
As shown in
By having the directions in which the shaft arm 525 of the crankshaft 524 extends to be in units of 90 degrees and associating the positional relationship between the pinion gear 620 and the rack 621, it is possible to set four types of conductive patterns according to the amount of pressing of the handle 222. Thus, four types of codes can be issued by a single code generation apparatus.
Furthermore, it is possible to issue more conductive patterns by finely dividing the directions in which the shaft arm 525 extends.
As shown in
The three electrode arrangement of the electrodes 54 and 56 is an arrangement which can be distinguished as a code pattern from others. Furthermore, for example, when human fingers in a form such as a right triangle touch a touch panel 31, it is preferable to have an arrangement where easy touching of the same form is difficult to accomplish. Furthermore, by increasing the number of electrodes provided in the electrode area 560 to 4 or 5, it may be made difficult for human fingers to easily touch the touch panel 31 with reproduction of the same shape.
As shown in
The electrode area 560 is provided with two electrodes 54 that are directly connected to the human body contact conductive material 21, and is further provided with one trigger electrode 56 which is connected to a human body contact conductive material 21 via the push button switch 60.
In the housing 2, there is a control unit 720 installed on a PCB circuit board 728. As an information processing apparatus, the control unit 720 includes a CPU (Central Processing Unit) 721, internal memories RAM (Random Access Memory) 722 and ROM (Read Only memory) 723, a wireless communication unit 724, a GPS (Global Positioning System) receiving unit 725, a USB (Universal Serial Bus) control unit 726, and a power supply unit 727. Furthermore, the operation unit 6 is provided with a push button switch 60 as one with a human body contact conductive material 21. The components other than the power supply unit 727 and the operation unit 6 may be configured with one semiconductor device or with a combination of a plurality of semiconductor devices.
The CPU 721, RAM 722, and ROM 722 constitute an information processing apparatus, and when the push button switch 60 is turned ON by pressing, the power is turned ON, necessary data is read from the ROM 722, and corresponding processing is performed. The ROM 723 stores an ID number corresponding to each of the code generation apparatuses 117, information to be transmitted to a smartphone when the push button switch 60 is pressed, and the like. The wireless communication unit 724 uses a wireless device such as WiFi or Bluetooth (registered trademark) which can serve to construct a wireless LAN (local area network). The GPS receiving unit 725 obtains positional information of the place where the code generation apparatus 117 is located. The USB control unit 726 controls USB connection with another apparatuses (not shown) when program update, data input/output, charging, or the like of the code generation apparatus 117 is performed. Furthermore, the USB control unit 726 may not be necessary. The power supply unit 727 supplies power to the control unit 720, and may be either a dry battery or a rechargeable battery as long as it can supply power that meets the specifications of the circuits and devices installed on the control unit 720. If a rechargeable battery is used, it may be chargeable via the USB connector 261.
A code recognition apparatus 3 is installed with an application program for recognizing a code generation apparatus 117 from detected coordinates when a touch panel 31 detects electrodes 5 of the code generation apparatus 117, and also for constructing a wireless LAN.
The operations and processings of a code generation apparatus based on this embodiment will be described. (1) When the code generation apparatus 117 is brought into contact with a touch panel 31 of a code recognition apparatus 3 and a human finger touches a human body contact conductive material 21, two reference electrodes 54 are detected by the touch panel 31. (2) Furthermore, when a push button switch 60 is pressed, a human body contact conductive material 21 and trigger electrodes 56 are electrically connected, and detected by the touch panel 31. (3) The code generation apparatus 117 further activates the control unit 720 and sends a connection request for establishing a wireless LAN by the information processing apparatus to the code recognition apparatus 3 within a predetermined amount of time.
(4) When three detected coordinates are obtained, the code recognition apparatus 3 analyzes the detected coordinates and determines whether or not they are the three information trigger points with an application program. If they are the information trigger points, a wireless LAN is activated and connection is accepted, and the apparatus that requested connection within the predetermined amount of time is determined to be the relevant code generation apparatus 117 and is connected.
(5) When the code generation apparatus 117 and the code recognition apparatus 3 are connected by the wireless LAN, the code generation apparatus 117 sends the ID number written in the ROM 723 by the information processing apparatus to the code recognition apparatus 3. The code recognition apparatus 3 checks the received ID number to determine whether the connection is correct. If the connection is correct, other necessary information is exchanged.
The detected electrode coordinates of the touch panel 31 are used as a communication activation trigger, and ID numbers and other kinds of information can be exchanged in large numbers by performing communication. Since the ID number is written in the ROM, the required number can be easily created.
As shown in
As shown in
By providing a dot code reading apparatus 730, not only is information input to the ROM 723 in advance but also other kinds of information embedded in a dot code, separately, can be transmitted using a code generation apparatus 117a to a smartphone which is a code recognition apparatus 3.
As shown in
As shown in
Furthermore, when a light conversion processing unit 742 is provided instead of a wireless communication unit 724, by bringing the code generation apparatus 117b into contact with a touch panel 31 and pressing the push button switch 60, the electrode coordinate information is recognized and checked by the code recognition apparatus 3. If the ID is correct, the light intensity of the touch panel 31 in the area corresponding to the photodiode 740 of the code generation apparatus 117b can be changed for issuing optical data patterns for ID confirmation, the photodiode 740 of the code generation apparatus 117b can receive light, and the light conversion processing unit 742 can confirm that the ID has been confirmed.
By providing a photodiode 740, a code generation apparatus 117b can receive information from the smartphone which is a code recognition apparatus 3 without using wireless communication.
The functions of the control unit 720 provided in the code generation apparatuses 117, 117a, and 117b can be used in combination, and furthermore, unnecessary functions can be omitted. Needless to say, the method of providing a control unit 720 provided in the code generation apparatuses 117, 117a, and 117b can also be applied to code generation apparatuses of other embodiments.
Next, various systems using the code generation apparatus will be described with reference to
(Company ID/Stamp Code Authentication System)
The slide switch which is the operation unit in
When a user uses an electronic stamp, it is desirable to construct a stamp ID authentication system in order to maintain confidentiality in performing charging, obtaining usage logs, and analyzing stamp codes issued by the electronic stamp. The flow of an authentication system is shown in
(1) First, the company ID of the company under contract and one or more stamp IDs used by the company are registered in the authentication server. A company ID-stamp ID table may be created. Although not shown, the plurality of stamp codes that can be issued with a multi-code stamp may be registered in the authentication server instead of a stamp ID. Of course, both the stamp IDs and the stamp codes may be registered.
(2) Next, when a predetermined processing such as reading a QR code or executing an application is performed by an information processing apparatus, a touch image that guides stamping of the electronic stamp is displayed on the touch panel.
(3) Next, the user holds and stamps an electronic stamp on the touch image displayed on the touch panel.
(4) Next, the touch panel on which the electronic stamp is pressed detects the coordinate positions (coordinate values) of a predetermined number of electrodes from the detected capacitance.
(5) Next, the information processing apparatus (including software) connected to the touch panel transmits at least the coordinate values and the company ID to the authentication server. Here, although not shown, the information processing apparatus may have a function of recognizing a stamp code from the coordinate values by pattern analysis and acquiring a stamp ID from the stamp code. Note that the information processing apparatus may have a function of only recognizing the stamp code and the function of acquiring a stamp ID from the stamp code may be in the authentication server. As a result, it is possible to keep confidential which stamp code corresponds to which stamp ID.
(6) Next, the authentication server recognizes the stamp code by pattern analysis from the received coordinate values of the electrodes, and acquires a stamp ID corresponding to the stamp code. Note that if the electronic stamp does not have a multi-code issuing function, there is one stamp code for each stamp, and the stamp code and the stamp ID correspond. When the stamp code is recognized from the coordinate values by pattern analysis and the stamp ID is acquired from the stamp code in procedure (5), the authentication server may receive both the stamp code and the stamp ID, or may acquire only the stamp code and the authentication server may transmit the stamp ID corresponding to the stamp code.
(7) Next, the authentication server collates the acquired stamp ID or stamp code along with the company ID with the registered codes.
(8) When the acquired stamp code agrees with the pre-registered stamp code, the authentication server transmits the stamp code to the information processing apparatus (including software) to complete the authentication. If not verified, the authentication server transmits a code indicating error to the information processing apparatus (including software) and there is no authentication. In the case of non-authentication, since an electronic stamp with an unregistered stamp code is used, it is necessary to re-execute from process (2) for the electronic stamp.
(9) Based upon the authenticated stamp code, the information processing apparatus (including software) executes access to contents such as WEB sites and various information processings.
Note that in process (1), a predetermined number of stamp codes corresponding to the stamp ID may be registered in the place of the stamp ID. In that case, the predetermined number of stamp codes registered together with the company ID are collated in process (5). The stamp ID authentication system can record the history of authenticated company IDs and stamp codes with time, and this can be utilized for measuring the effects of electronic stamps and for marketing research. If linked with a GPS device built into an information processing apparatus such as a smartphone, the history can be recorded together with the areas of use. In a stamp rally that uses an electronic stamp, if the location information of the electronic stamp is registered on the authentication server and the location information is included in the transmission information from the smartphone, even if the number of stamp IDs is limited, the stamp can be reliably identified by the stamp ID and the position information. In addition, a similar system can be provided for stamps, coupons, and point granting/erasing at stores. Furthermore, if it is found that a stamp is used with improbable position information, it can be acknowledged that the stamp is a counterfeit or a stolen item. Also, when an electronic stamp is given to each user, a stamp ID is recorded on each user's smartphone, and the smartphone ID and the stamp ID are registered on the authentication server. If an electronic stamp is stamped on a touch panel (including those of a smartphone or a tablet) installed at a predetermined location registered in the authentication server in advance, from the authentication server connected to the touch panel, it is also possible to send a history of stamp stamping on the authenticated user's smartphone and provide corresponding services.
For performing various charging by using electronic stamps, high security can be ensured by using PIN code input and passwords together with stamp code authentication. For PIN code and password input, if the application has a function to detect the rotation angle of the stamp, by placing a mark such as ▴ in the positive direction of the stamp, the order of the placement directions for stamp placements can be set as a password. A code generation apparatus of the present invention has a touch panel detect physical quantities and acquire multiple pieces of coordinate information, and an information processing apparatus built in or connected to the touch panel analyzes a pattern from the multiple pieces of coordinate information, and not only does it acknowledge the code generated from the code generation apparatus, it also calculates the orientation of the pattern, that is, the orientation of the code generation apparatus at the same time. Therefore, the stamp code and the orientation of the stamp can be recognized regardless of the orientation the stamp is placed on the touch panel. The accuracy is within ±several degrees, and even in consideration of human operability, up to a total of 8 directions (vertical, horizontal, and diagonal directions) can be reliably recognized. Thus, using the number of combinations including the order of the angles set with the eight directions θ1 to θ8 with the following rotation angle ranges, PIN codes or passwords can be set. The upward direction (0 degrees): range of 337.5 degrees<θ1≤22.5 degrees, oblique upper right direction (45 degrees): range of 22.5 degrees<θ2≤67.5 degrees, right direction (90 degrees): range of 67.5 degrees<θ3≤112.5 degrees, oblique lower right direction (135 degrees): range of 112.5 degrees<θ4≤157.5 degrees, downward direction (180 degrees): range of range of 157.5 degrees<θ5≤202.5 degrees, diagonally lower left direction (225 degrees): range of 202.5 degrees<θ6≤247.5 degrees, left direction (270 degrees): range of 247.5 degrees<θ7≤292.5 degrees, diagonally upper left direction (315 degrees): range of 292.5 degrees<θ8≤8 of 331 degrees. When inputting a PIN code or password, the stamp orientation may be changed in a predetermined order while maintaining touching or replacing each time. In order to make the operation smooth, first, the stamp may be placed in the upward direction, and then the direction may be changed for inputting the password.
(Content Download with a Browser)
The user photographs a QR code (registered with a URL including at least the company ID) printed on a poster, a flyer, or the like of stores and facilities that provide services using electronic stamps with a QR code reader (including the camera) provided in (or connected to) an information processing apparatus such as a smartphone, a tablet, or a PC. Then, the user reads the URL analyzed by a means of analysis of a smartphone or the like, accesses the URL with a browser, and downloads content data including HTML, JavaScript (JS), and predetermined data (including company ID). When content display or the like is executed, an electronic stamp touching screen is displayed on a display (touch panel) such as that of a smartphone. When the store side or the facility side sets a multi-stamp code for the electronic stamp (an electronic stamp that does not have a multi-stamp code function does not require special settings), and the electronic stamp is stamped, the touch panel detects the coordinate values of a predetermined number of electrodes, JS transmits at least the coordinate values and the company ID to the stamp ID authentication system of the authentication server, and receives the results of the stamp code analyzed from the coordinate values and the company ID authentication results by the authentication server. The information processing apparatus may have a function of recognizing a stamp code from the coordinate values by pattern analysis and acquiring a stamp ID from the stamp code. In that case, the authentication server may be set to receive the stamp code and the stamp ID. Thereafter, processing based on the stamp code is executed. Note that if the HTML or JS is acquired by downloading with a general-purpose browser, since the HTML or JS temporarily stored in the information processing apparatus can be analyzed and the URL or the like corresponding to images, video data, and contents can be acquired, these contents can spread to third parties. To provide contents only to those who can enjoy the service, it is necessary to develop a dedicated browser (app) with a QR code reading function, download, install, and use the dedicated browser according to the following procedure, and create a mechanism in which the URL of the connection site is concealed and content data cannot be stored. Note that by downloading and installing the application, a smartphone ID can be acquired, and push communication (email or information distribution to a smartphone user) is possible.
(1) Use a general-purpose browser to read the QR code for electronic stamps and download and install a dedicated browser.
(2) A dedicated browser is used to read the QR code for the electronic stamp, to acquire the corresponding URL, to download confidential HTML, JS, and predetermined data (including company ID and the like), and to acquire or stream contents.
(Application Development Using SDK (Software Development Kit))
If priority is given to real-time performances such as games, or if you do not want to go through an authentication server, an authentication system may be provided as an SDK and may be incorporated into an application or JS, to perform stamp code analysis of the coordinate values detected by the touch panel, and acquire and authenticate the stamp ID. In that case, an SDK in which a stamp ID (or stamp code) under contract along with a company ID is registered may be provided. As a result, an electronic stamp having a stamp code of a company not under contract cannot be used and security can be ensured.
(Setting of Subcodes (Dedicated Arguments))
Even with a single stamp code, it is possible to download different contents by adding a subcode (dedicated argument) to the URL registered in a QR code and changing the URL according to the combination of the company ID and each subcode. As a result, it is possible to realize multiple types of electronic stamps having the same stamp ID (an electronic stamp having a multi-stamp code function possesses a predetermined number of stamp codes, and in this embodiment, there are three types, A, B, and C). QR codes corresponding to these multiple types of electronic stamps registered with URLs including at least company IDs and subcodes are provided to users. Note that the company ID and subcodes may be included in the data area of the QR code.
(Content Creation with Subcode Setting by a Content Generator)
Furthermore, in the present invention, by using a content generator (CMS: content management system) that automatically creates electronic stamp contents, and by setting touch screen images (may also be videos) settings or by setting (for stamps that do not have the multi-stamp code function, only setting of the stamp ID) a multi-stamp code function capable of setting a multiple number of stamp codes with the operation unit, it is possible to make settings for content viewing and operations when an electronic stamp is stamped on a touch screen for each subcode. Note that although the above-mentioned operation unit has been described with respect to the setting of the multi-stamp code function, when stamping a stamp, the electrodes detected by the touch panel change, and depending on the combination, a large number of stamp IDs exceeding 1 million and stamp codes can be issued. However, with one stamp, the multi-stamp code function of the above-mentioned operation unit is limited to the generation of several types (in this embodiment, there are three types, A, B, and C) of stamp codes.
The user inputs a file name, URL, or execution software name in an interface screen as shown in
(Setting of Group Numbers (Dedicated Arguments))
When multiple stamp IDs for one company ID are set, and if the user stamps multiple electronic stamps with different stamp codes on one electronic stamp touch screen, different contents can be downloaded from each electronic stamp. In that case, it is possible to group stamp IDs targeted for a given touch screen, and by assigning a group number to the combination, the same stamp ID can be set at least to one part of the group number. Similar to a case in which subcode numbers are used, a group number (dedicated argument) is additionally included in the URL registered in the QR code by changing the group number while maintaining the same stamp ID, and by changing the URLs for users according to each combination of the company ID, group number, and subcode, it is possible to also download different contents. Furthermore, by concurrently using a subcode, it is possible to provide many circumstances where a plurality of electronic stamps can be used on a predetermined touch screen. In that case, it is necessary to include at least a group number and a subcode in the URL registered in the QR code. Note that the group number may also be encrypted, and such a format may be in any form or order. Thus, with a group number and a subcode, a QR code in which a URL including at least a company ID, a group number, and a subcode is registered is provided to the user. Note that the company ID, the group number, and the subcode for authentication may be included in the QR code data area.
(Content Creation with Group Numbers and Subcode Settings by a Content Generator)
Furthermore, in the present invention, a content for an electronic stamp may be automatically created for each group number and subcode using a content generator (CMS: content management system).
The user inputs a file name, URL, or execution software name in an interface screen as shown in
In the practical example of
(Electronic Stamp Own by an Individual and Security by PIN Code Entering)
In order to strengthen the security of prepaid payments on the Internet by users with electronic stamps, it is desirable have PIN code entry in addition to stamp ID (including stamp codes) authentication using a dedicated browser (application). PIN code input can be implemented by changing the placement orientation of a stamp as described above, and a PIN code cannot be input unless a PIN code inputter possesses a stamp. Currently, PIN codes are employed for electronic prepaid cards such as POSA cards used on the Internet with smartphones and PCs. The user purchases a prepaid card or the like at a convenience store or the like, obtains a PIN code by scratching off a concealed PIN code or by removing a concealment sticker, enters the PIN code at the time of prepaid payment, and settles a charge payment. However, “imposter fraud,” where fraud groups telephone elderly people, make them purchase prepaid electronic stamps for e-commerce at convenience stores, elicit the PIN code, and illegally use the prepaid electronic stamps, are becoming a social problem. The problem is that even if the fraud group does not obtain the prepaid card, fraud can be easily executed by making an elderly purchase a prepaid electronic stamp over the telephone and eliciting the PIN code. A mechanism is available in which the PIN code cannot be input unless a dedicated browser (application) is downloaded and installed, and the electronic stamp is stamped, when an electronic stamp is used for prepaid payment, in order for the user to input the PIN code. Furthermore, as described above, it is possible to make PIN code input only with an electronic stamp. As a result, “imposter fraud” is impossible with only the telephone, and the delivery of the electronic stamp is required. With “imposter fraud”, it is extremely difficult to implement delivery, and since evidence is likely to remain extremely high security can be provided.
On the other hand, PIN code input is also desirable when providing contents (including items with charges) such as videos, images, game items, or the like, and benefits such as coupons, points, or the like only to specific people. This is because if the content or coupon is copied and spread to a third party, the meaning of service for a specific person is lost. In addition, if economic services such as discounts and cash vouchers for specific people spread, companies will suffer serious damage. Therefore, when a user uses an electronic stamp, it can be made so that the service provider can provide various services only when a dedicated browser (application) is downloaded and installed, and the electronic stamp holder is authenticated. If the application is downloaded and installed, the ID of an information processing apparatus such as a smartphone can be acquired by the provider, and thus push communication can be performed from the provider side, and new services can be provided to the user in a timely manner. When push communication or content concealment is not required, a general-purpose browser may be used with emphasis on convenience. Note that a stamp equipped with a communication function and/or an information reading function, which will be described later, can secure a high level of security without having to enter a PIN code.
(Code Generation Apparatus with an Information Reading Function)
When a code generation apparatus is pressed in two stages onto a touch panel such as that of a smartphone or tablet, a stamp code is recognized by the smartphone or tablet from a conductive pattern formed with the detected plurality of electrodes. Regardless of where the code generation apparatus is placed or the orientation on the touch panel, since the conductive pattern of the first stage and/or second stage is formed with a geometrically unique arrangement, the position of the dot code reader of the code generation apparatus can be specified. For example, as shown in
Note that although a dot code reader installed in a code generation apparatus reads a dot code from an image photographed with visible light including color dots that are visible, as a dot code displayed on a display of a smartphone or the like that is a light-emitting medium, in order to photograph and read a dot code formed on a non-light emitting medium such as printed matter, since there is no interspace between the bottom of the code generator and the paper surface and light does not enter, it is necessary to irradiate light and read dots from the reflected light. Therefore, in order to read only a dot code that is printed superimposed on a graphic, the dots may be printed with infrared absorbing ink (carbon black ink, infrared absorbing stealth ink, or the like), and the other colors may be printed with ink that does not absorb infrared light. When infrared light are irradiated and the reflected light is photographed, since only the dot portion absorbs the infrared light and is imaged black, the dot code can be read. In this case, since visible light does not enter, it is not necessary to provide a filter that transmits only infrared light. Note that the CMOS sensor used in the dot code reader can image both visible light and infrared light.
Thus, it is possible to directly acquire a user's personal information without using the NET simply by placing a code generation apparatus on a touch screen of a user's smartphone. The above mentioned personal information may include as necessary information such as membership numbers, name, address, various Internet addresses, smartphone IDs, financial settlement information of credit cards and the like, certification information, health insurance information, and biometric information such as facial photos. Upon registering information associated with My Numbers, it may be made so that only information approved by the user can be read by a code generation apparatus.
(A Code Generation Apparatus Equipped with a Communication Function.)
An embodiment in which a communication function is installed in an electronic stamp which is a type of code generation apparatus will be described. If WiFi is installed as a communication function, the stamp address for each stamp is stored, and the stamp ID and the stamp address are registered with a linkage between them on the authentication server. Furthermore, a smartphone ID may be registered on the authentication server, and collation with the smartphone being used may be possible. When a stamp is stamped on the touch screen of a stamp-compatible application on a smartphone at a store or facility, an authentication server obtains a stamp ID, and concurrently, a stamp address is sent from the stamp to the authentication server by a stamping operation (switch is ON), and upon collating the stamp ID and stamp address registered on the server in advance with the acquired stamp ID and stamp address, authentication may be granted if they match, and thus forgery and theft can be prevented. If a theft is detected, the stolen stamp may be made not to be approved if the theft is registered on the server, or it may be made so that the thief if tracked and found. Note that in order to have the stamp usable in different places wherever it may be, it is only necessary to have names of the SSIDs the same. By registering information on the location of a stamp on the authentication server, it is possible to recognize where the stamp was stamped. The stamp stamping service may provide users with various contents via a server through WiFi communication.
Since it is not impossible to forge a capacitance code and generate the same stamp ID, as exemplified in this embodiment, by assigning a unique concealed stamp address to the stamp and performing authentication, extremely high security can be ensured. Furthermore, a one-time password may be transmitted from a stamp to an authentication server for authentication if a real-time clock is installed in the stamp and it is stamped on a smartphone. Based upon the authentication result, the processing of payments or the like intended to be implemented with a smartphone may be implemented. Also, when stamping on the smartphone, stamp authentication may be performed by having the smartphone send a request to the authentication server, having the authentication server send a one-time pass ID to the stamp, having a one-time password be generated based upon a concealed ID and concealed equation stored in the stamp, and having it be sent to the authentication server. Note that it is needless to say that any network means including LAN or the like other than with WiFi may be used. On the other hand, if a stamp equipped with a dot code reader or optical code reader as described above is used, a one-time password can be sent from a authentication server to the stamp simply by placing the stamp on the touch screen of a user's smartphone, and the one-time password may be sent to the authentication server for authentication. Alternatively, upon checking the one-time password with the stamp, authentication may be confirmed by sound output, confirmation light with LED or the such, or vibration by the stamp. If the stamp is equipped with a display, the result may be displayed on the stamp.
Note that it is possible to confirm whether or not a stamp has executed correctly if the stamp ID or stamp code acquired by the smartphone by stamp stamping on the touch screen to the stamp is sent to the stamp, and if the data received by the stamp, and the stamp ID and stamp code issued when the stamp was stamped are collated. Confirmation of misrecognition may be performed as a stand-alone, or by transmitting the information to the authentication server after collation confirmation, reliability of the system lowered by misrecognition of the stamp can be restored. Needless to say that confirmation of misrecognition as described above can be used together in any embodiment.
When BLE (including classic Bluetooth) is installed as a communication function, the stamp address is stored as the BLE device name for each stamp as in the above example, and the stamp ID and the stamp address are registered with a linkage between them on the authentication server. Furthermore, the smartphone ID may also be registered on the authentication server, and collation with the smartphone being used may be enabled. When a smartphone is stamped on a touch screen of a stamp-compatible application at a store or facility, a BLE installed in the stamp in a sleep state undergoes an advertising process as a peripheral to the central by a stamping operation (switch is ON). At the same time, the authentication server obtains a stamp ID, sends a stamp address corresponding to the stamp ID to the smartphone, and the central pairs with a BLE device having the stamp address. Upon completion of pairing, authentication and services similar to those with WiFi communication by stamp stamping can be implemented. Furthermore, when using BLE as a beacon, if a stamp address is stored as data for an advertising process and it is distributed unilaterally, even if the central and peripheral are not connected, the application displaying a stamp touch screen can obtain a stamp address instantaneously. Thus, the smart phone side (including the authentication server) can authenticate the stamp. In this case, since the central and the peripheral are not connected, data cannot be exchanged because the central is limited to acquiring one-time addresses. Here, in order to eliminate the possibility of a central operating on another smartphone acquiring and using the stamp address, it is desirable to advertise a one-time address by making the stamp address variable. In addition, the stamp ID or stamp code may be included in the peripheral data at the time of stamping. As a result, it is possible to authenticate by collating the stamp ID or stamp code acquired by a stamp being stamped on a smartphone. Note that it is needless to say that communication means with smartphones other than BLE may be used. The communication functions such as WiFi and BLE and the information reading functions such as the dot code reader and the optical code reader as described above may be used in any combination in all of the embodiments.
By placing a stamp in the segmented area, registering the stamp address and the like in a peripheral, the smartphone central acquires the data from entering/exiting of the area, and the user is able to obtain vibrational or sound output, or a display on the smartphone, that can perceptually urge the user to promptly perform stamping. Note that there may be a plurality of the above-mentioned areas, and different stamps may be set for each area, and the stamp address may be registered in the peripheral so that a new service can be provided every time the area is moved. Good. Note that the stamp installer may move the stamp and provide the same service.
If the stamp is affixed to a wall or poster, since there is no need for manpower, service can be provided more easily. Furthermore, if the smart phone transmits the data acquired from the peripheral to the authentication server, the smart phone can acquire a touch screen that can access new services and the contents thereof, and a strong motivation for stamp stamping can be obtain. Needless to say that it is also possible to provide different services depending on the position upon movement. Here, if the installation position of a stamp (including the installation position of a moved stamp) is also registered on the authentication server, a smartphone can track and search for a stamp with its GPS function. Furthermore, if the stamp is equipped with a GPS, the position may be transmitted to the smartphone as data from a peripheral.
(Personal Authentication of an Electronic Stamp Owner)
In the storage apparatus built-in a stamp, a person's name, date of birth, address, and biometric information such as photographs, and other basic personal information may be registered. Other information such as credit card information, bank accounts, licenses, health insurance cards and other certificates may be registered. Such information may be registered on the server. After a person selects information that can be disclosed on the person's smartphone, by stamping a stamp on another party's touch panel, the other party obtains the information by means of communication and by having the stamp holder state the date of birth, address, and the like, identity verification may be performed. By disclosing a photo, identity verification can be done easily. Such identity information may be deleted immediately to prevent leakage of identity information. In addition, when personal authentication is performed with a device, if the person makes an approval on the touch panel of the device upon request of provision of information from the device, by stamping the stamp on the touch panel of the device, biometric information of the user is transmitted from the stamp or server to the device and unmanned identity verification can be performed by matching it with biometric information acquired from the person on the spot (acquisition of face, fingerprint, iris, vein information, or the like by a camera or sensor set at a facility or in a device), and financial settlements, entry to important facilities, and operations of important equipment can be performed with high security. In order to facilitate biometric information authentication, although not shown, a fingerprint authentication apparatus or a camera may be attached to a stamp for personal authentication when the person uses the stamp. Note that the biometric information of a person can be easily registered by photographing the face, fingerprints, and iris with a camera installed on the person's smartphone, and the biometric information communicated from the smartphone may be stored in a storage apparatus built-in the stamp or registered on a server. Note that if a stamp is stolen, it may be set to refuse authentication of the stamp and information communication from the stamp or server may be stopped. Note that if a stamp equipped with a dot code reader or optical code reader is used, the user's personal information can be obtained directly by simply stamping the stamp on the touch screen of the user's smartphone without having to use the Internet. The above mentioned personal information may include as necessary information such as membership numbers, name, address, various Internet addresses, smartphone IDs, and biometric information such as facial photos. The method of personal authentication is as described above. In this case, it is desirable to enable the user to choose which personal information to disclose. Note that the user's personal information may be transmitted by an information reading apparatus by stamping a stamp set at a facility or in a device against a smartphone owned by the user. A stamp may have any shape or form, and instead of pressing a stamp on a smartphone, a smartphone may be placed on or over a stamp.
Furthermore, when using a BLE as a beacon, if a stamp holder carries a stamp and roams to various stores, facilities, or regions, the stamp address is stored as data for an advertising process, and it is unilaterally distributed, a stamp application can constantly transmit data such as a stamp address as a peripheral, an information processing apparatus equipped with a touch panel that plays a central role can acknowledge the existence of the stamp, and the information processing apparatus can catch the attention of the user by giving out signals to the stamp or a stamp holder's smartphone by outputting vibrations or sounds or by displaying to prompt the user to stamp the stamp on the information processing apparatus. With this stamping, various services can be provided to smartphone users. In such a system, information processing apparatuses may be searched for be stamped as if it were treasure hunting at an event, in a museum, at an amusement facility, in a mall or the like having many stores. Furthermore, by using a time stamp and position information at the time of stamp authentication as keys, events branched for individual users or guidance for new routes can be displayed, and thus various routings and experiences can be provided in the same venue. Furthermore, a new route guidance may be provided by reading a dot code or an optical code displayed on a paper medium or a display with an information reading apparatus installed in a stamp. In addition, a game-like element in which the location information of where the user stamped a stamp while moving and the location information of where a stamp placed at a fixed location such as a store was stamped are displayed “on a map only at the time of the stamping (for example, for 10 seconds to 3 minutes) and someone else tries to track the trace” may be added.
(Financial Settlements with an Electronic Stamp)
In an example of a financial settlement, when the store side applies a stamp on a touch screen of a purchaser's smartphone and the stamp is authenticated, the item names, the unit prices, the total payment amount, and the like of purchasing items sent from the store side system to a settlement server are received by and displayed on the smartphone, and after the purchaser confirms and approves the display contents, the purchaser selects a payment method, and information on a pre-registered bank account for withdrawal payments for financial settlements, credit cards, prepaid cards, or the like are transmitted to a settlement server, and when the payment server makes an approvement and a settlement, the store side system is immediately notified, and the purchase/payment procedure of the items is completed. Furthermore, icons such as “settlement,” “cancellation,” “single payment,” and “split payment,” and the like may be displayed on the purchaser's smartphone for selection and settlement. Note that if a payment cannot be completed, if there is overuse of a credit card, if there is a shortage in remaining balance for a prepaid card, or a bank account, such information may be displayed on a smartphone and recorded. In this way, payments can be made without having to issue receipts with purchased items, unit prices, payment totals, and the like, and the store side can eliminate the use of a printer, and the purchaser can record and manage purchased product information as data.
In addition, by issuing different stamp codes, by using a switchover switch on an operation unit of a stamp, any combination of processings such as “confirm purchasing items,” “settlement,” and “cancellation,” or “settlement,” “stamp granting,” and “stamp erasing,” or the like may be performed.
If you want to send money between individuals or corporations, if the sender enters the amount of money and the destination on the smartphone, applies a stamp and the stamp is authenticated, remittance information such as the destination and amount will be displayed again for confirmation, and upon approval, the remittance is notified to the receiving side and the remittance is carried out. In that case, in order to increase security so that a third party other than the principal cannot send or receive money, it made be set so that a password is input when the “settlement” icon is tapped. For this password input, if the application has a function for detecting the rotation angle of a stamp, a mark such as A can be provided for indicating the positive direction of the stamp, and the order of orientation of each placement upon placing the stamp can be set as the password. For the orientation of the touch screen (password input screen), for example, for a password set as “right (90 degrees), diagonally lower left (225 degrees), down (180 degrees), diagonally upper right (45 degrees),” it is sufficient to change the orientation of the stamp in this order while keeping the surface in contact, or to remove and place the stamp every time. In order to make the operation smooth, first, the stamp may be placed in the upward direction, and then the orientation may be changed for password input. Furthermore, if the sender's personal information (including biometric information) is registered on a stamp or server, the sender can be identified by a personal authentication as described above. For these financial transactions, in addition to the amount and date, classifications such as ‘Loan,’ ‘Gift,’ ‘Consideration,’ and the like may be set by issuing different stamp codes or according to the orientation of stamp placement using the stamp operation unit switchover switch. Also, the transmission side may confirm the sender and approve the transfer. Furthermore, when a stamp equipped with a dot code reader or optical code reader as described above is used, the user's personal information can be obtained from the user's smartphone via the dot code or optical code simply by placing the stamp on the touch screen of the user's smartphone. Such information may be acquired to determine whether a financial settlement can be allowed. The personal information may include information such as a settlement numbers, name, address, various Internet addresses, smartphone ID, and biometric information such as facial photo as necessary.
While the smartphone receives and displays the items, unit price, total payment amount, and the like for items for purchased sent from the store-side system to the payment server, bar codes, QR codes, or the like affixed or printed on the items purchased by the user may be photographed with the user's smartphone, the items, unit price, total payment amount, and the like for items for purchased may be tabulated, displayed, and confirmed, and then the store-side may stamp a stamp to obtain the information by an information obtaining apparatus, may display and confirm the information on a store-side system, and may perform a settlement. A display may be installed on the stamp, and the information may be displayed, confirmed, and settled.
(Granting/Erasing of Points, Coupons, and Stamps Using an Electronic Stamp)
In the use with points, coupons, and stamps, for a user to acquire a benefit, the user can acquire the benefit if a stamp is stamped on a touch screen displayed on a user's smartphone and authenticated by an approval server. In this case, a different stamp code may be issued by a switchover switch of the stamp operation unit and the provided service may be changed for each stamp code, for example such as for “point granting,” “point erasing,” “cancellation of operation,” “point granting/erasing,” “stamp granting/erasing,” and “coupon granting/erasing.” Here, if two types of processings such as “granting/erasing” are performed with one stamp code, a mark indicating orientation may be provided on the stamp, and the processing of “granting” may be performed when the stamp is placed in the vertical direction on the touch image, and the processing of “erasing” may be performed when the stamp is placed in the horizontal direction. Even by taking into consideration human operability, since up to a total of eight directions, that is, vertical and horizontal directions and diagonal directions, can be reliably recognized, even more functions may be assigned. Needless to say that the corresponding processings may be selected by a touching operation on a smartphone with a stamp with removal and placement. Furthermore, a variety of services may be provided easily by updating and communicating the contents of services stored in a stamp. Since the acquisition status and usage status of user points, coupons, and stamps can be stored on the server, services can be provided via the server. However, by installing a stamp authentication function in an application, and by having only direct communication between a stamp and smartphone via a BLE or the like, it is possible to provide authentication and services in an environment that does not use the Internet. As a result, information leakage from the server can be prevented. A method that does not use a server can also be used for personal authentication, and the like, and leakage of personal information can be prevented. The information stored in a stamp can be updated from any information processing apparatus such as a smartphone having a communication function, either wired or wireless. Note that authority to update the information may be granted only to specific persons, and the authority may be exercised upon authentication of personal information including the human body information.
Furthermore, when using a stamp equipped with an above-mentioned dot code reader or optical code reader, the user's personal information can be obtained directly without going through the Internet simply by placing the stamp on the touch screen of the user's smartphone. The personal information may include information such as membership numbers, name, address, various Internet addresses, smartphone ID, and biometric information such as facial photo as necessary. The method of personal authentication is as described above.
(Use in Ticketing)
A stamp ID or stamp code that approves an acquired ticket is registered on an authentication server in advance, and by stamping the corresponding stamp on a touch screen at the time of entry, allowance of entry is approved, and the user's smartphone displays the result. Furthermore, in order to strengthen security, by enabling a stamp read the ticket number or the like via an optical code or dot code from the user's smartphone, collation with the ticket number or the like stored in the stamp may be performed and permission of admission may be indicated with a sound, confirmation light with LED or the like, or vibration. Furthermore, for a stamp equipped with a communication function, an acquired ticket number or the like may be transmitted to the authentication server for verification. The result may be transmitted to the user's smartphone, or may be confirmed by sounds, light, vibration, or the like from a stamp. If a display is installed on the stamp, the result may be displayed on the stamp. An optical code or dot code displayed on the user's smartphone may include a one-time password by transmission from the cloud. As a result, security can be furthermore improved.
In addition, when a purchaser moves an item in the store from a shelf to a basket using barcode scanning, RFID, sensors, or the like, by reading a dot code printed on an item or on an affixed sticker with a stamp equipped with a dot code reading apparatus and making a payment after authentication using an electronic stamp, it is possible to complete a payment in the state where the purchaser is in the store with certainty.
(Installation of GPS and Communication Function in a Code Generation Apparatus)
An embodiment in which a GPS and a communication function are installed in an electronic stamp which is a kind of code generation apparatus will be described. It is assumed that the user carries the electronic stamp and uses it in various places. When a user possesses an electronic stamp, the corresponding stamp ID of the electronic stamp and user information are registered on the authentication server. By tracking the GPS installed in an electronic stamp, when an electronic stamp is stamped on a touch panel (including those of smartphones and tablets), an authentication server obtains the location information of the electronic stamp based on the stamp ID of the authenticated electronic stamp, and thus can specify where the electronic stamp was used. Even if the number of stamp IDs of the electronic stamp is limited, if position information from a GPS can always be tracked, it can be determined whether or not the electronic stamp is that possessed by a specific user. However, it is difficult for a GPS to recognize positions indoors. Note that if an electronic stamp and the smartphone ID of a smartphone owned by a user are registered together on a authentication server, even if location information from the GPS installed in the electronic stamp cannot be continuously tracked, the usage status of the electronic stamp is transmitted to the user's smartphone and it is possible to disable the use of the electronic stamp unless the user makes an approval. This also allows the user to approve the use of the electronic stamp by a third party.
By installing a communication function in an electronic stamp, it is possible to realize the following wide usage.
In addition, according to the present invention, it has become possible to realize the following functions that have been difficult with conventional electronic stamps.
[Description of the Dot Pattern]
Next, an example of the dot code (dot pattern) referred to above will be described with reference to
Here, the “dot pattern” refers to an information code encoded by a plurality of dot placement algorithms.
Note that the numeric information (code) obtained by reading the above dot pattern is a dot code and includes the notation of “dot code” as a general term. The same applies for the rest of the description.
Regarding the encoding algorithm of the information code by the dot pattern, well-known algorithms such as Grid Onput (registered trademark) of Gridmark Inc., the Anoto Pattern of Anoto Co., Ltd. may be used.
Note that Grid Onput (registered trademark) of Gridmark among the dot patterns will be described in detail later.
The dot pattern encoding algorithm itself is common in the case of reading with visible light and in the case of reading with infrared light, so it is not particularly restricted.
Besides this, the dot pattern is sufficient even if it cannot be visually recognized or even in the case in which it can be visually recognized but just as a pattern, and any dot pattern may be adopted.
Furthermore, by defining the coordinate values of a dot pattern, it is possible to encode different information codes in accordance with the reading position. Furthermore, the dot pattern includes a direction factor serving as a reference for encoding and decoding the information code, and by reading the direction, the rotation angle of the code generation apparatus 1 with respect to the dot pattern can be acquired. On the other hand, when the code generation apparatus 1 is tilted with respect to the dot pattern formation medium, it is also possible to acknowledge the direction and the degree of tilting of the generation apparatus 1 by a change in the brightness of the captured image.

[Assignment of a Code of an Information Dot in
The code assignment of an information dot is as shown in
That is, as shown in
As for the first example of the dot pattern, the present applicant refers to it as “GRID 0” as a tentative name.
A feature of “GRID 0” is that by using key dots, at least the range or the orientation of the dot pattern is made to be recognizable.
“GRID 0” has the following configuration as shown in
(1) Information Dot
An information dot is a dot for storing information.
Note that ways of viewing an information dot is as shown in
(2) Reference Dot
A reference dot is a dot placed at a plurality of preset positions and is for specifying the position of a virtual point or a virtual region to be described later.
(3) Key Dot
Though not shown, a key dot is a dot placed by shifting a reference dot or is a dot placed in a position displaced from the placement position of a reference dot in addition.
A Key dot is for specifying the reference orientation for information dots with respect to reference points and virtual points or for information dots arranged in the virtual region with respect to reference points. By determining this reference orientation, it is possible to provide information in the orientation of the information dot with respect to the virtual point and have it read. Furthermore, it is possible to specify the range of a dot pattern in which one piece of data is defined by a plurality of information dots. Thus, even if the dot patterns are placed vertically and horizontally, it is possible to decode the data by reading the range of the dot pattern.
(4) Virtual Point or Virtual Area
A virtual point or virtual area is specified by the arrangement of reference dots.
As for the second example of the dot pattern, the present applicant refers to it as “GRID 0” as a tentative name.
In “GRID 5”, in the place of the key dot of “GRID 0”, the range and orientation of the dot pattern is made to be recognized by utilizing “how to arrange reference dots.” In order to recognize the orientation of the dot pattern utilizing “how to arrange the reference dots”, regardless of what kind of point the reference dot arrangement is centered on and how much it is rotated (excluding) 360°, the arrangement must be non-axisymmetric so that it is not identical with that before rotation. Furthermore, it is necessary to be able to recognize the range and orientation of dot patterns even when a plurality of dot patterns repeatedly arranging vertically and/or horizontally are connected or concatenated.
Note that in “GRID 5,” the orientation of the dot pattern is recognized using pattern recognition. That is, the shape of a dot pattern formed by the reference dots is stored in a storage means. Then, by collating the image of the read dot pattern with the shape stored in the storage means, the orientation of the dot pattern can be recognized.
With “GRID 5”, the reference dots may be arranged in any way, as long as the arrangement of the dots form a recognizable pattern.
