The present application is based on, and claims priority from Japanese Application No. 2013-159039, filed Jul. 31, 2013, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present invention relates to a printing system and printing apparatus, and more particularly, to a printing apparatus that forms an image on an intermediate transfer medium using an ink ribbon in which are disposed image formation panels and peel off panels and that transfers the image to a printing medium, and a printing system provided with the printing apparatus and a host computer.
Conventionally, such a printing apparatus has been known widely that forms an image such as a photograph of face and character information on a printing medium such as aplastic card. In such a printing apparatus, for example, an image (mirror image) is formed on a transfer film (intermediate transfer medium) with a thermal head via an ink ribbon, and next the image formed on the transfer film is transferred to a printing medium.
Generally, this type of printing apparatus constitutes a printing system together with a host computer. On a hard disk of the host computer is installed object generation application software for generating a desired image object corresponding to a printing medium, and when necessary, a printer driver for generating printing data for the printing apparatus from the image object, and the image objector printing data generated on the host computer side is delivered to the printing apparatus side (for example, see Patent Document 1).
In addition, on the printing medium exist regions such as a magnetic stripe arrangement area, IC storage area (particularly, contact type IC terminal area) and a signature field of an owner to which a transfer layer of the transfer film should not be transferred. When the transfer layer of the transfer film is transferred to the magnetic stripe arrangement area or the contact type IC storage area, there is the risk that a functional disorder occurs in the printing medium, and when the transfer layer of the transfer film is transferred to the signature field, it is difficult for the owner to sign in trying to sign.
To solve the problem, for example, Patent Document 2 discloses techniques for forming an image on a transfer film with an image formation panel of Y (Yellow), M (Magenta), C (Cyan) and Bk (Black) using an ink ribbon in which are disposed image formation panels and peel off panels, peeling off (an image of) a transfer layer in a region that should not be transferred to a recording medium in the image formed on the transfer film, and then, transferring the image with the transfer layer peeled off formed on the transfer film to a printing medium.
The techniques of Patent Document 2 as described above are to peel off the transfer layer in a predetermined region of the transfer film that should not be transferred to the recording medium with the peel off panel, do thereby not impair functions of the magnetic stripe and contact type IC, enable a signature to be made smoothly, and are thus excellent techniques. However, since an image is once formed with Y, B, C, Bk and the like in a predetermined region of the transfer film that should not be transferred to the recording medium and the transfer layer in the predetermined region is peeled off with the peel off panel, there is the risk that boundaries with images in the periphery of the peeled region become jagged (see
In view of the above-mentioned matter, it is an object of the present invention to provide a printing system and printing apparatus provided with improvements in the image quality of an image formed on a printing medium.
To attain the above-mentioned object, in a first aspect of the present invention, a printing system, which is provided with a printing apparatus that forms an image on an intermediate transfer medium using an ink ribbon in which are disposed an image formation panel and a peel off panel and that transfers the image to a printing medium and a host computer, is provided with an object generation/non-transfer region setting device for generating a desired image object corresponding to the printing medium and setting a non-transfer region indicating that a transfer layer of the intermediate transfer medium is not transferred to the printing medium inside a region of the image object, a converting device for converting the image object generated in the object generation/non-transfer region setting device into printing data, a modified printing data generating device for generating modified printing data by modifying, in the printing data converted in the converting device, a gray-scale value of printing data inside the non-transfer region set by the object generation/non-transfer region setting device, printing data inside a region that is larger than the non-transfer region by a predetermined dimension and that includes the non-transfer region, or printing data of a region larger than the non-transfer region by a predetermined dimension to a predetermined gray-scale value or less, or modifying a gray-scale value of the printing data inside the non-transfer region to a predetermined gray-scale value or less while performing gradation processing in a region larger than the non-transfer region by a predetermined dimension, a printing section that has a thermal head with a plurality of heating elements lined and that peels off a transfer layer of the intermediate transfer medium by selectively heating the heating elements for the peel off panel according to position information of the non-transfer region set by the object generation/non-transfer region setting device after forming an image on the intermediate transfer medium by selectively heating the heating elements for the image formation panel according to the modified printing data generated in the modified printing data generating device or before forming the image, and a transfer section that transfers, to the printing medium, an image with the transfer layer peeled off formed on the intermediate transfer medium in the printing section.
In the first aspect, an operator generates a desired image object corresponding to a printing medium using the object generation/non-transfer region setting device. Further, by obtaining assistance from the object generation/non-transfer region setting device, in generating the image object, the operator sets the non-transfer region indicating that the transfer layer of the intermediate transfer medium is not transferred to the printing medium inside the region of the image object. The converting device converts the image object generated in the object generation/non-transfer region setting device into printing data. Next, the modified printing data generating device generates modified printing data by modifying, in the printing data converted in the converting device, a gray-scale value of a) printing data inside the non-transfer region set by the object generation/non-transfer region setting device, b) printing data inside a region that is larger than the non-transfer region by a predetermined dimension and that includes the non-transfer region, or c) printing data of a region larger than the non-transfer region by a predetermined dimension to a predetermined gray-scale value or less, or d) modifying a gray-scale value of the printing data inside the non-transfer region to a predetermined gray-scale value or less while performing gradation processing in a region larger than the non-transfer region by a predetermined dimension. Next, the printing section selectively heats heating elements for the image formation panel according to the modified printing data generated in the modified printing data generating device to form an image on the intermediate transfer medium. In the modified printing data, the gray-scale value of the printing data of the predetermined region (inside the non-predetermined region in (a) and d), inside the region that is larger than the non-transfer region by a predetermined dimension and that includes the non-transfer region in b), and the region larger than the non-transfer region by a predetermined dimension in c)) to a predetermined gray scale value or less, and therefore, image formation with the image formation panel is not performed in a region of the intermediate transfer medium corresponding to the predetermined region modified in the printing data. Further, the printing section peels off a transfer layer of the intermediate transfer medium by selectively heating the heating elements for the peel off panel according to position information of the non-transfer region set by the object generation/non-transfer region setting device, after forming an image on the intermediate transfer medium or before forming the image. The description is given to the relationship between the region (peel off region) in which the transfer layer of the intermediate transfer medium is peeled off with the peel off panel and the region (non-printing region) in which image formation is not performed with the image formation panel. On the intermediate transfer medium, the peel off region and the non-printing region are the same (overlap) in above-mentioned a) and d), the non-printing region is larger than the peel off region (the peel off region is included in the non-printing region) in above-mentioned b), and the non-printing region adjoins to the outside the peel off region in above-mentioned c). Then, the transfer section transfers, to a printing medium, an image with the transfer layer peeled off formed on the intermediate transfer medium in the printing section.
In addition, the object generation/non-transfer region setting device may be disposed on the printing apparatus side, and with consideration given to operability, processing speed and the like, is preferably disposed on the host computer side. The converting device may be disposed on either the printing apparatus side or the host computer side. The modified printing data generating device is disposed on the printing apparatus side when the converting device is disposed on the printing apparatus side, and may be disposed on either the printing apparatus side or the host computer side when the converting device is disposed on the host computer side.
In the first aspect, the modified printing data generating device may modify the gray-scale value of the printing data inside the non-transfer region, the printing data inside the region that is larger than the non-transfer region by a predetermined dimension and that includes the non-transfer region, or the printing data of the region larger than the non-transfer region by a predetermined dimension to a gray-scale value of 0. Further, the modified printing data generating device may perform gradation processing by setting a gray-scale value of printing data on a boundary of the region adjacent to the side opposite to the non-transfer region of the region larger than the non-transfer region by a predetermined dimension to be smaller toward the modified gray-scale value gradually or stepwise. Furthermore, the system is further provided with a storage device for beforehand storing the relationship between a type of recording medium and the non-transfer region corresponding to the type of recording medium, and the object generation/non-transfer region setting device may set the non-transfer region from the relationship stored in the storage device corresponding to the type of recording medium.
Further, in the ink ribbon are disposed the image formation panel having a plurality of color panels and a Bk (Black) panel and the peel off panel, and the converting device converts the image object with R (Red), G (Green) and B (Blue) as color components into the printing data with Y (Yellow), M (Magenta) and C (Cyan) each as a color component, and may perform dither conversion on the image object with Bk as a color component. At this point, in converting into the printing data with Y, M and C each as a color component, the converting device may further perform edge enhancement conversion.
Furthermore, to attain the above-mentioned object, in a second aspect of the present invention, a printing apparatus that forms an image on an intermediate transfer medium using an ink ribbon in which are disposed an image formation panel and a peel off panel and that transfers the image to a printing medium is provided with a storage device for storing input printing data and position information of a non-transfer region indicating that a transfer layer of the intermediate transfer medium is not transferred to the printing medium corresponding to the printing data, a modified printing data generating device for generating modified printing data by modifying, in the printing data stored in the storage device, a gray-scale value of printing data inside the non-transfer region, printing data inside a region that is larger than the non-transfer region by a predetermined dimension and that includes the non-transfer region, or printing data of a region larger than the non-transfer region by a predetermined dimension to a predetermined gray-scale value or less, or modifying a gray-scale value of the printing data inside the non-transfer region to a predetermined gray-scale value or less while performing gradation processing in a region larger than the non-transfer region by a predetermined dimension, according to the position information of the non-transfer region stored in the storage device, a printing section that has a thermal head with a plurality of heating elements lined and that peels off a transfer layer of the intermediate transfer medium by selectively heating the heating elements for the peel off panel according to the position information of the non-transfer region stored in the storage device after forming an image on the intermediate transfer medium by selectively heating the heating elements for the image formation panel according to the modified printing data generated in the modified printing data generating device or before forming the image, and a transfer section that transfers, to the printing medium, an image with the transfer layer peeled off formed on the intermediate transfer medium in the printing section.
In the second aspect, the printing apparatus is provided with the storage device, and the storage device stores the input printing data and the position information of the non-transfer region indicating that a transfer layer of the intermediate transfer medium is not transferred to the printing medium corresponding to the printing data. Then, as in the first aspect, the modified printing data generating device generates the modified printing data, the printing section performs image formation/peeling of the transfer film on the intermediate transfer medium, and the transfer section transfers the image formed on the intermediate transfer medium to the printing medium. The second aspect also exerts the same effects as in the first aspect.
According to the present invention, since in the modified printing data generated in the modified printing data generating device, a gray-scale value of printing data of a predetermined region (non-printing region) is modified to a predetermined gray-scale value or less, when the printing section forms an image on the intermediate transfer medium with the image formation panel, image formation with the image formation panel is not performed in a region of the intermediate transfer medium corresponding to the non-printing region. Further, when the printing section peels off the transfer layer of the intermediate transfer medium with the peel off panel of the ink ribbon, since the region (peel off region) of the transfer layer to peel off is smaller or the same as the non-printing region, or is adjacent to the non-printing region, image formation is not performed in the peel off region or in the periphery thereof, and the region to peel off with the peel off panel is made easy to peel off. Therefore, it is possible to obtain the effects of preventing the occurrence of jaggies on the boundary with the image in the periphery of the peeled region on the intermediate transfer medium, and enabling the image quality of the printing medium to be improved after transferring the image formed on the intermediate transfer medium in the transfer section.
With reference to drawings, described below is an Embodiment in which the present invention is applied to a printing system for printing and recording text and image on a card, while performing magnetic or electric information recording on the card.

<Printing Apparatus>
As shown in
The information recording section A is comprised of a magnetic recording section 24, non-contact type IC recording section 23, and contact type IC recording section 27.
The media storage section C aligns and stores a plurality of cards in a standing posture, is provided at its front end with a separation opening 7, and feeds and supplies starting with the card in the front row with a pickup roller 19.
The fed card Ca (also see
Around the reverse unit F in the turn direction are disposed the magnetic recording section 24, non-contact type IC recording section 23, and contact type IC recording section 27. Then, the roller pairs 20, 21 form a medium carry-in path 65 for carrying in toward one of the information recording sections 23, 24 and 27, and data is magnetically or electrically written on the card Ca in the recording sections.
The image formation section B is to form an image such as a photograph of face and character data on frontside and backside of the card Ca, and a medium transport path P1 for carrying the card Ca is provided on an extension of the medium carry-in path 65. Further, in the medium transport path P1 are disposed transport rollers 29, 30 that transport the card Ca, and the rollers are coupled to a transport motor not shown.
The image formation section B is provided with a film-shaped medium transport apparatus, a printing section B1 that first prints an image, with a thermal head 40, on a transfer film 46 transported with the transport apparatus, and a transfer section B2 that subsequently transfers the image formed on the transfer film 46 to the card Ca existing in the medium transport path P1 with a heat roller 33.
On the downstream side of the image formation section B is provided a medium transport path P2 for carrying the printed card Ca to a storage stacker 60. In the medium transport path P2 are disposed transport rollers 37, 38 that transport the card Ca, and the rollers are coupled to a transport motor not shown.
A decurl mechanism 36 is disposed in between the transport roller 37 and the transport roller 38, presses the card center portion held between the transport rollers 37, 38, and thereby corrects curl generated by thermal transfer with the heat roller 33. Therefore, the decurl mechanism 36 is configured to be able to shift to positions in the vertical direction as viewed in
The storage section D is configured to store cards Ca sent from the image formation section B in the storage stacker 60. The storage stacker 60 is configured to shift downward in
The image formation section B in the entire configuration of the above-mentioned printing apparatus 1 will be further described specifically.
The transfer film 46 is wound around each of a wind-up roll 47 and feed roll 48 of a transfer film cassette rotated by driving a motor Mr2. A film transport roller 49 is a main driving roller for carrying the transfer film 46, and a transport amount and transport halt position of the transfer film 46 is determined by controlling driving of the roller 49. The film transport roller 49 is coupled to a stepping motor not shown. The motor Mr2 is also driven at the time of driving the film transport roller 49, is for the wind-up roll 47 to reel the fed transfer film 46, and is not driven as main transport of the transfer film 46.
Pinch rollers 32a and 32b are disposed on the periphery of the film transport roller 49. Although not shown in
An ink ribbon 41 is stored in an ink ribbon cassette 42, a supply spool 43 for supplying the ink ribbon 41 and wind-up spool 44 for winding the ink ribbon 41 are stored in the cassette 42, the wind-up spool 44 is driven with a motor Mr1, and the supply spool 43 is driven with a motor Mr3. Forward-backward rotatable DC motors are used for the motors Mr1 and Mr3. Further, “Se2” shown in
A platen roller 45 and thermal head 40 form the printing section B1, and the thermal head 40 is disposed in a position opposed to the platen roller 45. The thermal head 40 has a plurality of heating elements lined in the main scanning direction, and these heating elements are selectively heated and controlled by a head control IC (not shown) according to printing data, and an image is printed on the transfer film 46 using the sublimation ink ribbon 41. Further, these heating elements are also selectively heated and controlled in peeling off a transfer layer of a predetermined region of the transfer film 46 with the peel off panel (PO) based on position information of the set PO region, as described later (see
The ink ribbon 41 with which printing on the transfer film 46 is finished is peeled off from the transfer film 46 with a peeling roller 25 and peeling member 28. The peeling member 28 is fixed to the cassette 42, the peeling roller 25 comes into contact with the peeling member 28 in printing, and the roller 25 and member 28 nip the transfer film 46 and ink ribbon 41 to peel. Then, the peeled ink ribbon 41 is wound around the wind-up spool 44 by driving the motor Mr1, and the transfer film 46 is transported to the transfer section B2 including a platen roller 31 and heat roller 33 by the film transport roller 49.
In the transfer section B2, the transfer film 46 is nipped together with the card Ca by the heat roller 33 and platen roller 31, and the image on the transfer film 46 is transferred to the card surface. In addition, the heat roller 33 is attached to an up-and-down mechanism (not shown) so as to come into contact with and separate from the platen roller 31 via the transfer film 46.
The configuration of the printing section B1 will specifically be described further together with its action. As shown in
Then, spring members 51 (51a, 51b) are mounted on the support shaft 58, and end portions on which the pinch rollers 32a, 32b are installed of the pinch roller support member 57 respectively contact the spring members 51, and are biased to the direction of the film transport roller 49 by the spring forces.
The bracket 50 comes into contact with the cam operation surface of a cam 53 in a cam receiver 81, and is configured to shift in the horizontal direction viewed in the figure with respect to the film transport roller 49, corresponding to rotation in the arrow direction of the cam 53 with a cam shaft 82 as the axis driven by a drive motor 54 (see
At this point, the pinch roller 32b in a farther position from a shaft 95 as a rotation axis of the bracket 50 first comes into press-contact with the film transport roller 49, and next, the pinch roller 32a comes into press-contact. In this way, by arranging the shaft 95 that is the rotation axis higher than the film transport roller 49, the pinch roller support member 57 comes into contact with the film transport roller 49 while rotating, instead of parallel shift, and there is the advantage that the space in the width direction is less than in the parallel shift.
Further, the press-contact forces when the pinch rollers 32a, 32b come into press-contact with the film transport roller 49 are uniform in the width direction of the transfer film 46 by the spring members 51. At this point, since the long holes 76, 77 are provided on the opposite sides of the pinch roller support member 57 and the support shaft 58 is fixed to the fix portion 78, it is possible to adjust the pinch roller support member 57 in three directions, and the transfer film 46 is transported in a correct posture by rotation of the film transport roller 49 without causing skew. In addition, adjustments in three directions described herein are to (i) adjust the parallel degree in the horizontal direction of the shafts of the pinch rollers 32a, 32b with respect to the shaft of the film transport roller 49 to uniform the press-contact forces in the shaft direction of the pinch rollers 32a, 32b with respect to the film transport roller 49, (ii) adjust shift distances of the pinch rollers 32a, 32b with respect to the film transport roller 49 to uniform the press-contact force of the pinch roller 32a on the film transport roller 49 and the press-contact force of the pinch roller 32b on the film transport roller 49, and (iii) adjust the parallel degree in the vertical direction of the shafts of the pinch rollers 32a, 32b with respect to the shaft of the film transport roller 49 so that the shafts of the pinch rollers 32a, 32b are perpendicular to the film travel direction.
Then, the bracket 50 is provided with a tension receiving member 52 that comes into contact with a portion of the transfer film 46 which is not wound around the film transport roller 49 when the bracket 50 moves toward the film transport roller 49.
The tension receiving member 52 is provided to prevent the pinch rollers 32a, 32b from retracting from the film transport roller 49 respectively against the biasing forces of the spring members 51 due to the tension of the transfer film 46 occurring when the pinch rollers 32a, 32b bring the transfer film 46 into press-contact with the film transport roller 49. Accordingly, the tension receiving member 52 is attached to the front end of the end portion on the rotation side of the bracket 50 so as to come into contact with the transfer film 46 in the position to the left of the pinch rollers 32a, 32b viewed in the figure.
By this means, the cam 53 is capable of directly receiving the tension occurring due to elasticity of the transfer film 46 through the tension receiving member 52. Accordingly, the pinch rollers 32a, 32b are prevented from retracting from the film transport roller 49 due to the tension and from decreasing the press-contact forces of the pinch rollers 32a, 32b, thereby maintain the winding state in which the transfer film 46 is brought into intimate contact with the film transport roller 49, and are able to perform accurate transport.
As shown in
The bracket 50A is comprised of a substrate 87, and cam receiver support portion 85 formed by bending the substrate 87 in the direction of the platen support member 72, and the cam receiver support portion 85 holds a cam receiver 84. Then, a cam 53A rotating on a cam shaft 83 as the axis driven by the drive motor 54 is disposed between the substrate 87 and the cam receiver support portion 85, and is configured so that the cam operation surface and cam receiver 84 come into contact with each other. Accordingly, when the bracket 50A moves in the direction of the thermal head 40 by rotation of the cam 53A, the platen support members 72 also shift to bring the platen roller 45 into press-contact with the thermal head 40.
The spring members 99 and cam 53A are thus disposed vertically between the bracket 50A and platen support members 72, and it is thereby possible to store the platen shift unit within the distance between the bracket 50A and platen support members 72. Further, the width direction is held within the width of the platen roller 45, and it is possible to save space.
Moreover, since the cam receiver support portion 85 is fitted into bore portions 72a, 72b (see
When the platen roller 45 comes into press-contact with the thermal head 40, the spring members 99 connected to respective platen support members 72 act each so as to uniform the press-contact force on the width direction of the transfer film 46. Accordingly, when the transfer film 46 is transported by the film transport roller 49, the skew is prevented, and it is possible to perform thermal transfer by the thermal head 40 accurately without the printing region of the transfer film 46 shifting in the width direction.
The substrate 87 of the bracket 50A is provided with a pair of peeling roller support members 88 for supporting opposite ends of the peeling roller 25 via spring members 97, and when the bracket 50A moves to the thermal head 40 by rotation of the cam 53A, the peeling roller 25 comes into contact with the peeling member 28 to peel off the transfer film 46 and ink ribbon 41 nipped between the roller and member. The peeling roller support members 88 are also provided respectively at opposite ends of the peeling roller 25 as in the platen support members 72, and are configured so as to uniform the press-contact force in the width direction on the peeling member 28.
A tension receiving member 52A is provided in an end portion on the side opposite to the end portion on the shaft support 59 side of the bracket 50A. The tension receiving member 52A is provided to absorb the tension of the transfer film 46 occurring in bringing the platen roller 45 and peeling roller 25 respectively into press-contact with the thermal head 40 and peeling member 28. The spring members 99 and 97 are provided so as to uniform the press-contact force on the width direction of the transfer film 46, and in order for the spring members 99 and 97 not to be inversely behind the tension of the transfer film 46 and decrease the press-contact force on the transfer film 46, the tension receiving member 52A receives the tension from the transfer film 46. In addition, since the tension receiving member 52A is also fixed to the bracket 50A as in the above-mentioned tension receiving member 52, the cam 53A receives the tension of the transfer film 46 via the bracket 50A, and is not behind the tension of the transfer film 46. By this means, the press-contact force of the thermal head 40 and platen roller 45 and the press-contact force of the peeling member 28 and peeling roller 25 are held, and it is thereby possible to perform excellent printing and peeling. Further, any error does not occur in the transport amount of the transfer film 46 in driving the film transport roller 49, the transfer film 46 corresponding to the length of the printing region is accurately transported to the thermal head 40, and it is possible to perform printing with accuracy.
The cam 53 and cam 53A are driven by same drive motor 54 with a belt 98 (see
When the image formation section B is in such a waiting position as shown in
Then, when the cam 53 and cam 53A are rotated in conjunction with each other and are in the state as shown in
In this state, when transport of the transfer film 46 is started by rotation of the film transport roller 49, at the same time, the ink ribbon 41 is also wound around the wind-up spool 44 by operation of the motor Mr1 and transported in the same direction. During this transport, a positioning mark provided in the transfer film 46 passes through a sensor Se1 and shifts a predetermined amount, and at the time the transfer film 46 arrives at a printing start position, printing by the thermal head 40 is performed on the predetermined region of the transfer film 46. Particularly, since the tension of the transfer film 46 is large during printing, the tension of the transfer film 46 acts on the direction for separating the pinch rollers 32a, 32b from the film transport roller 49 and the direction for separating the peeling roller 25 and platen roller 45 from the peeling member 28 and thermal head 40. However, as described above, since the tension of the transfer film 46 is received in the tension receiving members 52, 52A, the press-contact forces of the pinch rollers 32a, 32b are not decreased, it is thereby possible to perform accurate film transport, the press-contact force of the thermal head 40 and platen roller 45 and the press-contract force of the peeling member 28 and peeling roller 25 are not decreased either, and it is possible to perform accurate printing and peeling. The ink ribbon 41 with which printing is finished is peeled off from the transfer film 46 and wound around the wind-up spool 44.
A shift amount by transport of the transfer film 46 i.e. a length in the transport direction of a printing region to undergo printing is detected by an encoder (not shown) provided in the film transport roller 49, rotation of the film transport roller 49 is halted corresponding to detection, and at the same time, winding by the wind-up spool 44 by operation of the motor Mr1 is also halted. By this means, finished is printing of the first color on the printing region of the transfer film 46 with the thermal head 40.
Then, when the cam 53 and cam 53A are further rotated in conjunction with each other and are in the state as shown in
Then, the control state by the cam 53 and cam 53A becomes the state as shown in
Thus, the operation in the printing position and transport position is repeated until printing of all colors (in this Embodiment, four colors of Y (Yellow), M (Magenta), C (Cyan) and Bk (Black)) is finished, and further, is repeated in peeling off the transfer layer of a predetermined region of the transfer film 46 with the peel off panel (PO). Then, when printing (image formation on the transfer film 46 and peeling of the transfer layer in the predetermined region) with the thermal head 40 is finished, the image-formed region of the transfer film 46 is transported to the heat roller 33, and at this point, the cam 53 and cam 53A shift to the state as shown in
Such an image formation section B is divided into three units 90, 91, 92 and each is integrated.
In the first unit 90 as shown in
In
The thermal head 40 is disposed in the position opposed to the platen roller 45 with a transport path of the transfer film 46 and ink ribbon 41 there between. The thermal head 40, members related to heating and cooling fan 39 are integrated into the third unit 92 as shown in
The first unit 90 collectively holds the platen roller 45, peeling roller 25 and tension receiving member 52A varying in position by printing operation in the movable bracket 50A, and thereby eliminates the need of position adjustments among the members. Moreover, by shifting the bracket 50A by rotation of the cam 53, it is possible to shift the members to predetermined positions. Further, since the bracket 50A is provided, it is possible to store in the same unit as that of the fixed film transport roller 49, the transport drive portion by the film transport roller 46 required to transport the transfer film with accuracy and the transfer position regulation portion by the platen roller 45 are included in the same unit, and therefore, the need is eliminated for position adjustments between both portions.
In the second unit 91 as shown in
In the pinch roller support member 57, the spring members 51a, 51b are attached to the support shaft 58, and their end portions are respectively brought into contact with the opposite ends of the pinch roller support member 57 that supports the pinch rollers 32a, 32b to bias to the direction of the film transport roller 49. Then, in the pinch roller support member 57, the support shaft 58 is inserted in the long holes 76, 77, and is fixed and supported in the center portion by the bracket 50.
A spring 89 for biasing the pinch roller support member 57 toward the bracket 50 is provided between the bracket 50 and the pinch roller support member 57. By this spring 89, the pinch roller support member 57 is biased in the direction of moving backward from the film transport roller 49 of the first unit 90, and therefore, it is possible to easily pass the transfer film 46 through between the first unit 90 and the second unit 91 in setting the transfer film cassette in the printing apparatus 1.
The second unit 91 holds the pinch rollers 32a, 32b, and tension receiving member 52 varying in position corresponding to printing operation in the bracket 50A, shifts the pinch rollers 32a, 32b, and tension receiving member 52 by shifting the bracket 50A by rotation of the cam 53, and thereby simplifies position adjustments between the rollers and member, and position adjustments between the pinch rollers 32a, 32b and the film transport roller 49. Such a second unit 91 is disposed opposite the first unit 90 with the transfer film 46 there between.
By thus making the units, it is also possible to pull each of the first unit 90, second unit 92 and third unit 93 out of the main body of the printing apparatus 1 as in the cassette of each of the transfer film 46 and ink ribbon 41. Accordingly, in replacing the cassette due to consumption of the transfer film 46 or ink ribbon 41, when the units 90, 91 and 92 are pulled out as required, it is possible to install the transfer film 46 or ink ribbon 41 readily inside the apparatus in inserting the cassette.
As described above, by combining the first unit 90 into which are integrated the platen roller 45, bracket 50A, cam 53A, and platen support member 72, and the second unit 91 into which are integrated the pinch rollers 32a, 32b, bracket 50, cam 53 and spring members 51, and placing and installing the third unit 92 with the thermal head 40 attached thereto opposite the platen roller 45, it is possible to perform assembly in manufacturing the printing apparatus and adjustments in maintenance with ease and accuracy. Moreover, by integrating, it is possible to perform removal from the apparatus with ease, and the handleability as the printing apparatus is improved.
<Ink Ribbon Cassette>
The cassette 42 storing the ink ribbon 41 will specifically be described next. As shown in
The wind-up spool 44 is disposed rotatably on one side (upper side in
Further, the cassette 42 has a cover 17 that covers the wind-up spool 44 and the supply spool 43 in the direction crossing the base 11. The cover 17 is fixed to the end portion along the longitudinal direction of the base 11. Further, from the lower side to upper side in
Accordingly, the ink ribbon 41 fed out of the supply spool 43 is transported to come into slide-contact on one surface side with the shafts 14, 13, peeling member 28 and shaft 12 to be wound around the wind-up spool 44, or inversely, to come into slide-contact with the shaft 12, peeling member 28 and shafts 14, 13 to be wound around the supply spool 43.
Described herein is the arrangement relationship between the sensor Se2 and thermal head 40 on the main-body side and the shafts when the cassette 42 is inserted in the main-body apparatus. As shown in
Described further is the relationship among the ink ribbon 41, supply spool 43, wind-up spool 44 and the like when the cassette 42 is inserted in the main-body apparatus. The length of the ink ribbon 41 laid between the supply spool 43 and the wind-up spool 44 is set to be shorter than the total length of three ribbon panels among ribbon panels of successive four colors of Y (Yellow), M (Magenta), C (Cyan) and Bk (Black), and further, along the ink ribbon 41 laid between the supply spool 43 and the wind-up spool 44, each of the distance between the supply spool 43 and the sensor Se2, the distance between the sensor Se2 and the thermal head 40, the distance between the thermal head 40 and the peeling member 28, and the distance between the peeling member 28 and the wind-up spool 44 is set to be shorter than the length of a ribbon panel of one color of the ink ribbon 41.
With reference to
The spool main body 110 has a cylindrical ribbon holding portion 118 having fringes 113, 114 at opposite ends to hold the ink ribbon 41, the engagement portion 112 provided on one end portion adjacent to the fringe 113, and a shaft portion 119 with a diameter smaller than that of the cylindrical portion of the ribbon holding portion 118 provided on the side opposite to the engagement portion 112 adjacent to the fringe 114.
The fringes 113, 114 regulate the position of winding of the ink ribbon 41 around the ribbon holding portion 118 in the shaft direction of the spool main body 110. Therefore, when the spool main body 110 rotates, an unused ink ribbon 41 is supplied from the ribbon holding portion 118 without causing misregistration (in the case of the supply spool 43), and a used portion of the ink ribbon 41 is properly wound around the ribbon holding portion on the wind-up side (in the case of the wind-up spool 44).
The engagement portion on the main-body apparatus side associated with the engagement portion 112 of the supply spool 43 is comprised of a plurality of members. In other words, a support shaft 125 is fixed to the housing 2, and axially supports the disk-shaped engagement member having a gear on the outer edge portion to be rotatable. On the side engaging in the engagement portion 112 of the engagement member, two engagement convex portions 122 of shapes different from the convex portion (groove portion) of the engagement portion 112 are provided to protrude opposite each other (so as to make a phase difference of 180° with respect to the rotation direction of the engagement portion). In the engagement portion 122 is formed a groove formed from an inclined surface linearly formed on the convex-portion side surface having a predetermined inclined angle, and a bottom portion connecting between adjacent convex-portion inclined surfaces (in
In inserting the cassette 42 in the main-body apparatus, there is the case that the front end of the convex portion of the engagement portion 112 of the spool main body 110 comes into contact with (hits) the front end of the engagement convex portion 122 provided in the engagement member on the apparatus main body side, and is not inserted smoothly. Since the engagement member is provided slidably in the shaft direction of the support shaft 125, when the front ends of the convex portions of the engagement portion 112 hit the front ends of the engagement convex portions 122, the engagement convex portions 122 once retract to the apparatus frame side (on the side opposite to the spool main body 110). Subsequently, when the engagement member or spool main body 110 rotates, the engagement convex portions 122 enter into the groove between convex portions of the engagement portion 112, and are biased to the spool main body 110 side by the spring 124, and the engagement convex portions 122 and the (groove between) convex portions of the engagement portion 112 come into point-contact in two points.
The gear of the engagement member meshes with a gear 121C, and to the gear 121C is fixed a rotating plate 121A with a slit (not shown) formed on the same axis. Further, in a position to sandwich the rotating plate 121A is disposed a transmission integral-type sensor 121B comprised of a light emitting device and a light receiving device. Accordingly, the rotating plate 121A and sensor 121B constitute the encoder 121 as a rotation amount detecting device for detecting a rotation amount of the supply spool 43 that supplies the ink ribbon 41. In addition, an encoder (not shown) provided in the above-mentioned film transport roller 49 is configured in the same way. In other words, a gear that is the same as the gear 123 shown in
With the printing processing on the transfer film 46 with the thermal head 40, the ink ribbon 41 is transported from the supply spool 43 side to the wind-up spool 44, and according to transport, the ribbon diameter of the supply spool 43 shifts from the large diameter to the small diameter, while the ribbon diameter of the wind-up spool 43 changes from the small diameter to the large diameter. With the change, the tension in winding the ink ribbon 41 around the wind-up spool 44 shifts from high to low, and inversely, the tension in rewinding the ink ribbon 41 around the supply spool 43 shifts from low to high. Therefore, in this example, used are two motors of the motor Mr1 that is the rotation drive source of the wind-up spool 44 and motor Mr3 that is the rotation drive source of the supply spool 43.
Described next is control and electric system of the printing apparatus 1. As shown in
<Control Section>
As shown in
The microcomputer 102 is connected to an external bus. The external bus is connected to an interface, not shown, to communicate with the higher apparatus 201, and buffer memory 101 to temporarily store printing data to print on the card Ca, recording data to magnetically or electrically record in a magnetic stripe portion or stored IC of the card Ca, and the like.
Further, the external bus is connected to a sensor control section 103 that controls signals from various sensors, an actuator control section 104 that controls motor drivers and the like for outputting drive pulses and drive power to respective motors, a thermal head control section 105 to control thermal energy to heating elements constituting the thermal head 40, an operation display control section 106 to control the operation panel section 5, and the above-mentioned information recording section A.
The power supply section 120 supplies operation/drive power to the control section 100, thermal head 40, operation panel section 5 and information recording section A.
<Characteristics and Others of the Printing System 200>
Described next are characteristics and others of the printing system 200 of this Embodiment.
(Application Software)
In the higher apparatus 200 is installed object generation application software which functions as “an object generation/non-transfer region setting device” and generates each printing object, while generating a desired image comprised of a plurality of printing objects to print on the card Ca, and a printer driver (application software) which functions as “a converting device” and generates printing data for the printing apparatus 1 based on the data generated in the object generation application software.
(Generation of Printing Object)
Herein, generation of a printing object will be described using an example.
Generally, as well as the full name of the owner, since the card Ca includes various printing objects (text data) such as a name of a company to which the owner belongs and the ID number and is comprised thereof, it is possible to generate the other objects (other than the full name) according to the above-mentioned example, and a plurality of generated printing objects is stored in the same folder. Further, generally, on the card Ca are often printed printing objects (image data) such as a photograph of face of the owner, a logo mark of the company and background image of the card, and these pieces of image data may be stored in the same folder or may be stored in another folder. In addition, such image data may be retrieved from an image input apparatus 204, or may use image data stored in another computer.
(Generation of Image Object and Setting of Peel Off Region)
The operator generates a desired image to print on the card Ca using a plurality of printing objects stored in the above-mentioned folder. In other words, the higher apparatus 201 displays the entire preview image (also see
As described in the column of background art, on the card Ca exist regions such as a magnetic stripe arrangement area, IC (particularly, contact type IC) storage area and a signature field of an owner to which the transfer layer of the transfer film 46 should not be transferred. In obtaining the desired image object (before the arrangement of a plurality of printing objects, during the arrangement, or after the arrangement), the operator sets (designates) a non-transfer region indicating that the transfer layer of the transfer film 46 is not transferred to the card Ca inside the region of the image object. The printing apparatus 1 side forms the non-transfer region by peeling off the transfer layer of the transfer film 46 using the peel off panel of the ink ribbon 41, and therefore, herein after, the “non-transfer region” is called the peel off region, and is abbreviated as the PO region.
In the object generation application software of this example, the operator clicks a PO region setting (manual) button to display the PO region of the rectangular predetermined size on the preview screen, is capable of changing optionally the size L in the X-axis direction and size N in the Y-axis of the PO region by positioning a pointer (cursor) in the peel off end coordinates Q of the displayed PO region and arbitrarily left-dragging with the mouse, and is capable of shifting the PO region to an arbitrary position by positioning a pointer in a portion except the peel off end coordinates Q inside the PO region and left-dragging to an arbitrary position with the mouse. In addition, a box indicating numeric values of the peel off start coordinates P, and the size L in the X-axis direction and size N in the Y-axis of the PO region is concurrently displayed (not shown), and the operator is also able to directly change the numeric value inside the box.
The above-mentioned example is the example in the case where the operator sets the PO region manually, and when a standard product is used for the card Ca, it is possible to set easier. For example, the object generation application software has information for defining the relationship between the type of card and the position information (peel off start coordinates P, and the size L in the X-axis direction and size N in the Y-axis of the PO region) of the PO region corresponding to the type of card as program data, and by the operator clicking a PO region setting (selection) button, displays a list (not shown) to specify the type of card Ca. For example, the operator places a checkmark in the box corresponding to the type of card, and thereby specifies (selects) the type of card Ca from the displayed list. The CPU of the higher apparatus 201 determines the position information of the PO region corresponding to the specified type of card Ca by referring to the program data, and displays the PO region on the preview image.
The CPU of the higher apparatus 201 judges whether the OK button of the preview image is clicked, and in the case of being clicked, determines that the image object to print on the card Ca and the peel off data is established. Herein, importance is that each printing object is set for the position information. Accordingly, as well as the above-mentioned printing information, the printing information is provided with the position information of the printing objects. Further, the CPU retrieves the peel off start coordinates P(x,y), and the size information (L, N), and stores the position information of the PO region in a predetermined folder (peel off folder) as peel off data. In addition, the peel off folder may be the same as the folder in which the printing objects are stored.
Next, according to the object generation application software, the CPU of the higher apparatus 201 converts each printing object of the text data into image data such as a bitmap, and generates a single image object into which all image data is integrated for each surface of the card. Then, using the API (Application Program Interface) function, the CPU outputs the image object, the peel off data, and data that is beforehand input from the input apparatus 203 to record on the magnetic stripe and IC of the card Ca to the GDI (Graphic Device Interface, see Japanese Unexamined Patent Publication No. 2004-194041). Using the DDI function (Device Driver Interface, see Japanese Unexamined Patent Publication No. 2002-91428), the GDI outputs the image object, the peel off data, and the data to record on the magnetic stripe and IC of the card Ca to the printer driver.
(Printer Driver)
According to the printer driver, the CPU of the higher apparatus 201 receives the data output from the object generation application software via the GDI, determines various parameter values to control recording operation in the printing apparatus 1, and generates the printing data to perform recording on the card Ca, the peel off data, and the data to record on the magnetic stripe and IC with recording commands to transmit to the printing apparatus 1.
(Image Conversion)]
Described herein is image conversion from the image object into printing data by the printer driver. In this Embodiment, the printer driver performs the following three types of image conversion. 1) Conversion from the image object with R (Red), G (Green) and B (Blue) as color components into the printing data with Y (Yellow), M (Magenta) and C (Cyan) each as a color component. 2) Edge enhancement conversion (for example, conversion for enhancing the contour of the face and the like) performed in the conversion of above-mentioned 1). 3) Dither conversion on the image object with Bk (Black) as a color component. The dither conversion is performed when ink of the Bk ribbon panel of the ink ribbon 41 is melt-type ink as in this example. Further, in the case where the color ribbon panel of the ink ribbon 41 is of the melt-type (the case except this example), the dither conversion is also performed on the color ribbon panel. In addition, in this Embodiment, in the image conversion of above-mentioned 1), each pixel constituting the printing data of R, G, B, Bk is converted in the 256-level gray scale in the range of gray scale values of 0 to 255.
(Printing Apparatus)
On the other hand, the buffer memory 101 of the control section 100 in the printing apparatus 1 stores various parameter values that are recording control commands, the printing data, the peel off data and the data to record on the magnetic stripe and IC.
(Generation of Modified Printing Data)
The CPU (herein after, simply referred to as CPU) of the microcomputer 102 of the control section 100 executes a modified printing data generation routine to generate modified printing data with modification made to the received printing data, based on the printing data and peel off data stored in the buffer memory 101.
As shown in
As shown in
Next, in step 226, the CPU reads the size information (L, N) of the PO region from the peel off data, and calculates the peel off end coordinates Q (x+L,y+N) from the size information. Next, in step 228, the CPU calculates the size (b,d) in the X-axis and Y-axis directions of the non-printing region (size (b,d)=size (L+1,N+1)). The non-printing region undergoes mask processing described later, and therefore, herein after, the size in the X-axis and Y-axis directions of the non-printing region is referred to as the mask size. Then, in step S230, the CPU calculates the mask end coordinates S (a+b,c+d) expressed as the coordinates of a position farthest from the origin point O (0,0) in the non-printing region, from the mask start coordinates R calculated in step 224, and the mask size (b,d) calculated in step 228, finishes the mask region generation subroutine, and proceeds to step S206 in
In step 206 in
As shown in
Next, in step 214 in
The above-mentioned description is for the contact type IC storage area, and as in this example, when the peel off data of the stripe arrangement area exists, further when the signature field of the owner of the card Ca and the like exist, the printing data is similarly modified.
In addition, in this Embodiment, the processing is performed in the order of generation of image object and setting of PO region→image conversion→generation of modified printing data, and in theory, it is conceivable to process in the order of generation of image object and setting of PO region→generation of modified printing data→image conversion. In the latter case, generation of modified printing data is performed on only two objects, color image object and Bk image object, and as compared with the former case where the processing is performed on the printing data of each of Y, M, C and Bk and is performed total four times (see steps 208, 210, 212, and 216 in
(Image Formation on the Transfer Film 46)
According to the modified printing data of each of Y, M, C and Bk generated in the modified printing data generation routine, for the image formation panel of each of color ribbon panels of Y, M and C and Bk ribbon panel of the ink ribbon 41, the printing section B1 selectively heats the heating elements of the thermal head 40 to form an image. As shown in
(Peeling of the Transfer Layer of the Transfer Film 46)
Next, according to the position information of the PO region, for the peel off panel (PO) of the ink ribbon 41, the printing section B1 selectively heats the heating elements of the thermal head 40, and thereby peels off the transfer layer of the region corresponding to the PO region on the ink ribbon 41 of the transfer film 46.
(Transfer to the Card Ca)
The transfer section B2 transfers the image with the transfer layer peeled formed on the transfer film 46 as described above to the card Ca. By this means, the printing processing on one surface of the card Ca is finished. In addition, in transferring images to both surfaces of the card Ca, for example, after transferring an image to one surface of the card Ca, the card Ca may be transported backward toward the reverse unit F on the medium transport path P1, and rotated 180° in the reverse unit F to transfer an image to the other surface of the card Ca. Alternatively, after transferring an image to one surface of the card Ca, the card Ca may be carried to the storage stacker 60 (once discharged from the printing apparatus 1) along the medium transport path P2 to perform the printing processing again on the other surface of the card Ca.
(Advantages and Others)
Advantages and others of the printing system 200 of this Embodiment will be described next while comparing with the problems of the conventional example.
In the conventional example, since an image is once formed also in a predetermined region of the transfer film 46 that should not be transferred to a card using the image formation panel of Y, M, C and Bk of the ink ribbon 41, and the transfer layer of the predetermined region is peeled off with the peel off panel (PO), as shown in
In the printing system 200 of this Embodiment, in the modified printing data, pixels of the printing data of the non-printing region are set (deleted) for a gray-scale value of 0. Therefore, as shown in
Modifications of this Embodiment will be described next.
(Modification 1)
As shown in
(Modification 2)
Further, as shown in
(Modification 3)
Further, in the aspect (this Embodiment) as shown in
In addition, this Embodiment shows the ink ribbon 41 formed by repeating the image formation panel of Y, M, C and Bk and the peel off panel (PO) in this order in a face sequential manner, but the invention is not limited thereto. For example, the ink ribbon 41 may be formed by repeating the peel off panel (PO) and the image formation panel of Y, M, C and Bk in this order in a face sequential manner. In this case, in a manner opposite to this Embodiment in which the transfer layer of the transfer film 46 is peeled off with the peel off panel after forming an image on the transfer film 46 with the image formation panel, it is possible to peel off the transfer layer of the transfer film 46 with the peel off panel (PO) before forming an image on the transfer film 46 with the image formation panel. Further, the ribbon may have a protection layer and the like as well as the image formation panel of Y, M, C and Bk and the peel off panel (PO). Furthermore, this Embodiment shows the example in which color ribbon panels are in the order of Y, M and C, and as long as the ribbon has at least above-mentioned three colors, it is possible to change the order as appropriate. Moreover, the ribbon may have ribbon panels of other colors (for example, silver and gold).
Further, this Embodiment shows the example in which the higher apparatus 201 side performs generation of the image object, setting of the PO region and image conversion, and the printing apparatus 1 side performs generation of the modified printing data, and since the printing apparatus 1 is provided with the operation panel section 5, the printing apparatus 1 side may perform generation of the image object and setting of the PO region. In addition, with consideration given to operability, processing speed and the like, it is preferable that the higher apparatus 201 side performs such processing. Furthermore, image conversion may be performed in the printing apparatus 1. Still furthermore, generation of the modified printing data is performed on the printing apparatus 1 side when image conversion is performed on the printing apparatus 1 side. When image conversion is performed on the higher apparatus 201 side, the generation may be performed on either the printing apparatus 1 side or the higher apparatus 201 side.
Moreover, in the case of applying the present invention to the printing apparatus 1, it is always not necessary that the printing apparatus 1 is connected to the higher apparatus 201 as in this Embodiment. For example, when the printing data, the position information of the PO region and the like is input to the printing apparatus 1 via a storage medium such as USB memory, it is possible to perform the same processing as in this Embodiment.
Further, this Embodiment describes the example of setting the non-printing region as the region that is larger than the PO region by predetermined dimensions and that includes the PO region at the center, but the invention is not limited thereto, and a region that is larger than the PO region by predetermined dimensions and includes the PO region may be set as the non-printing region. In this case, an intersection point (center) of virtual lines of diagonal lines of the rectangular non-printing region and an intersection point (center) of virtual lines of diagonal lines of the rectangular PO region are different positions. Moreover, this Embodiment exemplifies 0.5 mm in each of the X-axis direction and Y-axis direction as predetermined dimensions, but the invention is not limited thereto, and for example, the dimension may be different between the X-axis direction and the Y-axis direction such as 0.4 mm in the X-axis direction and 0.6 mm in the Y-axis direction.
Furthermore, as shown in
Then, this Embodiment shows the example in which the platen roller 45 is shifted to the thermal head 40 side to nip the ink ribbon 41 and transfer film 46, but the present invention is not limited thereto. For example, the thermal head 40 may be shifted to the platen roller 45 side to nip the ink ribbon 41 and transfer film 46. Further, this Embodiment exemplifies the platen roller 45 disposed opposite the thermal head 40, but the present invention is not limited to a roller or rotating body-shaped platen. For example, a cradle-shaped platen, plate-shaped platen and the like may be used which receive the pressing force from the thermal head 40.
Further, this Embodiment shows the aspect of modifying gray-scale values of the printing data to a gray-scale value of 0 in the non-printing region, and instead of modifying gray-scale values to a gray-scale value of 0, modification may be made to a range of gray-scale values in which the ink ribbon 41 does not produce a color. In the printing apparatus of this Embodiment, since the ink ribbon does not produce a color at a gray-scale value of about 20, in the mask processing in
