The present application is based on, and claims priority from JP Application Serial Number 2019-057194, filed Mar. 25, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a tape detection mechanism which detects a tape which is fed thereto and a tape printing apparatus.
In the related art, as disclosed in JP-A-2013-159409, there is known a tape printing apparatus provided with a tape detection mechanism which detects a tape which is fed thereto. The tape detection mechanism is provided with a rotating body slider which slides due to the tape which is fed thereto, a rotating member which pivots due to the rotating body slider sliding, a detection arm which extends in radial directions of the rotation member, and a slider detector which detects the leading end portion of the detection arm. Since the pivoting amount of the leading end portion of the detection arm is great in relation to the disposition amount of the rotating body slider, even when the thickness of the tape, which is fed thereto, is thin, the leading end portion of the detection arm is appropriately detected by the slider detector.
In the tape detection mechanism of the related art, when the thickness of the tape which is fed is thick, since the pivoting amount of the detection arm increases by a corresponding amount, the tape detection mechanism increases in size in order to secure the space for the detection arm to pivot.
According to an aspect of the present disclosure, there is provided a tape detection mechanism including a first pivoting member provided to pivot about a detection pivoting shaft, a second pivoting member pivotally linked to a pivot linking portion provided on the first pivoting member, a pivoting contact section with which the second pivoting member comes into contact when the first pivoting member and the second pivoting member pivot in a first pivoting direction about the detection pivoting shaft as the tape, which is fed thereto, comes into contact with the first pivoting member, and a sensor which detects the second pivoting member which comes into contact with the pivoting contact section.
According to another aspect of the present disclosure, there is provided a tape printing apparatus including a first pivoting member provided to pivot about a detection pivoting shaft, a second pivoting member pivotally linked to a pivot linking portion provided on the first pivoting member, a pivoting contact section with which the second pivoting member comes into contact when the first pivoting member and the second pivoting member pivot in a first pivoting direction about the detection pivoting shaft as the tape, which is fed thereto, comes into contact with the first pivoting member, a sensor which detects the second pivoting member which comes into contact with the pivoting contact section, and a print head which performs printing on the tape.
Hereinafter, a description will be given of an embodiment of the tape printing apparatus with reference to the accompanying drawings. Although an XYZ Cartesian coordinate system is displayed in the following drawings, this is merely for the convenience of explanation and is not intended to limit the following embodiment in any manner. Numerical values indicating the number of each part or the like are all merely exemplary and are not intended to limit the following embodiment in any manner.

As illustrated in
The discharge frame 35 is formed in a substantially rectangular plate-shape which is long in the Y directions. The parts of the tape discharge unit 33 are attached to the surface of the +X side of the discharge frame 35. A slit-shaped tape passage port 47, which is cut into the discharge frame 35 from the end portion of the +Z side to the −Z side, is formed in a substantially middle portion of the discharge frame 35 in the Y directions. The tape passage port 47 is located where the tape 213 fed from the tape feed-out port 215 of the tape cartridge 201 mounted in the cartridge mounting portion 7 to the tape discharge port 19 passes through.
The discharge motor 37 is provided in the vicinity of the corner portion of the −Y size and the −Z side of the apparatus frame. The discharge motor 37 serves as the drive source of a first discharge roller 95a (described later). As described later, the first discharge roller 95a includes a case in which the discharge motor 37 is used as the drive source and a case in which a feed motor 153 (refer to
The discharge gear train 39 is provided on the end portion of the −Z side of the discharge frame 35. The discharge gear train 39 is provided with a feed motor-side gear train 49, an discharge motor-side gear train 51, and a clutch mechanism 55. The feed motor-side gear train 49 transmits the rotation of the feed motor 153 input via a feed gear train (not illustrated) to the first discharge roller 95a. The discharge motor-side gear train 51 transmits the rotation input thereto from the discharge motor 37 to the first discharge roller 95a.
The clutch mechanism 55 is provided between the discharge motor-side gear train 51 and a roller gear 53 provided on the same shaft as the first discharge roller 95a. The clutch mechanism 55 switches between a state in which the clutch mechanism 55 transmits the rotation between the discharge motor-side gear train 51 and the roller gear 53 and a state in which the clutch mechanism 55 cuts off the transmission between the discharge motor-side gear train 51 and the roller gear 53. The clutch mechanism 55 is provided with a clutch gear 57 (refer to
When the discharge motor 37 rotates, the clutch gear 57 meshes with the roller gear 53 and the rotation of the discharge motor 37 is transmitted between the discharge motor-side gear train 51 and the roller gear 53. Accordingly, the first discharge roller 95a rotates using the discharge motor 37 as the drive source. On the other hand, when the feed motor 153 rotates, the clutch gear 57 disconnects from the roller gear 53 and the transmission of the rotation of the feed motor 153 between the discharge motor-side gear train 51 and the roller gear 53 is cut off. Accordingly, the first discharge roller 95a rotates using the feed motor 153 as the drive source.
As illustrated in
The slide support portion 59 is fixed to the −Y side of the tape passage port 47. The sliding member 61 is supported by the slide support portion 59 to be capable of sliding in the Y directions. The movable holder 93 is fixed to the +Y side of the sliding member 61. A pivoting contact section 69 (refer to
The interlocking block 63 is fixed to the −Y side of the sliding member 61 via a sensor substrate 149 (described later). The interlocking block 63 is provided with a large block portion 71 attached to the sliding member 61, a small block portion 73 provided of the −Y side of the large block portion 71, and a rod portion 75 protruding to the −Y side from the small block portion 73. A rod-side engaging portion 77 (refer to
The interlocking lever 65 is provided to be capable of pivoting on a lever shaft 79 fixed to the discharge frame 35. The interlocking lever 65 extends in the Z directions and is provided with a lever shaft insertion portion 81, a lever-side engaging inclined surface 83, a rod insertion hole 85, a lever-side protruding portion 87, and the lever-side engaging portion 89.
The lever shaft insertion portion 81 is provided at substantially the middle portion of the interlocking lever 65 in the Z directions. The lever shaft 79 is inserted through the lever shaft insertion portion 81. The lever-side engaging inclined surface 83 is provided of the +Y side of the end portion of the interlocking lever 65 of the +Z side. When the mounting portion cover 5 is closed, the lever-side engaging inclined surface 83 engages with the interlocking protrusion 27 which enters from the interlocking opening 21. The rod insertion hole 85 is provided on the end portion of the interlocking lever 65 of the −Z side. The rod insertion hole 85 is formed in a substantially elliptical shape which is long in the Z directions and penetrates the interlocking lever 65 in the Y directions. The rod portion 75 is inserted through the rod insertion hole 85. The lever-side protruding portion 87 is provided on an opening edge portion of the rod insertion hole 85 of the +Y side. The lever-side protruding portion 87 engages with the end portion of the pinching spring 67 of the −Y side. The lever-side engaging portion 89 is provided of the −X side of the opening edge portion of the rod insertion hole 85 of the −Y side. The lever-side engaging portion 89 engages with the rod-side engaging portion 77. In
The pinching spring 67 is provided between the small block portion 73 and the lever-side protruding portion 87 to fit onto the rod portion 75. The pinching spring 67 applies a force to the interlocking block 63 in the +Y direction when the interlocking lever 65 is considered to be fixed. For example, it is possible to use a compressed coil spring as the pinching spring 67.
In the interlocking mechanism 41 configured in this manner, when the mounting portion cover 5 is closed, the interlocking lever 65 pivots in a lever first direction 65a while further compressing the pinching spring 67 to transition from the state illustrated in
Meanwhile, when the mounting portion cover 5 is opened, the interlocking lever 65 is caused by the pinching spring 67 to pivot in a lever second direction 65b which is the opposite direction from the lever first direction 65a to transition from the state illustrated in
The discharge feeding section 43 feeds the tape 213 dispensed from the tape feed-out port 215 of the tape cartridge 201 mounted to the cartridge mounting portion 7 toward the tape discharge port 19. The discharge feeding section 43 is provided with a fixed holder 91, the movable holder 93, and the first discharge roller 95a, as illustrated in
The fixed holder 91 is fixed to the +Y side of the tape passage port 47. Meanwhile, the movable holder 93 is attached to the +Y side of the sliding member 61 supported by the slide support portion 59 to be capable of sliding in the Y directions. A holder-side spring locking portion 99 is provided on the movable holder 93 at a substantially middle portion in the Z directions of the −Y side.
As illustrated in
The first discharge roller shaft 101 is supported by the fixed holder 91 to be capable of rotating. The first discharge roller shaft 101 is joined to the roller gear 53 (refer to
The second discharge roller 95b is provided close to the −X side of the −Y side with respect to the first discharge roller 95a and rotates to follow the first discharge roller 95a. The second discharge roller 95b is provided with a second discharge roller shaft 107 extending in the Z directions, four second pulley portions 109 formed in substantially circular plate shapes, and eight of the second dividing roller portions 111 formed in substantially circular plate shapes.
The second discharge roller shaft 107 is supported by the movable holder 93 to be capable of rotating. The second pulley portions 109 and the second dividing roller portions 111 are fixed to the second discharge roller shaft 107 and rotate integrally with the second discharge roller shaft 107. The four second pulley portions 109 are provided at positions corresponding to the four first belt roller portions 103 in the axial directions, that is, the Z directions of the second discharge roller shaft 107. In other words, the four second pulley portions 109 are provided distributed into two pairs in the Z directions in the same manner as the four first belt roller portions 103. The discharge belts 97 span the spaces between the second pulley portions 109 and third pulley portions 115 (described later). The eight second dividing roller portions 111 are provided at positions corresponding to the eight first non-belt roller portions 105 in the axial directions of the second discharge roller shaft 107. The second dividing roller portions 111 pinch the tape 213 between the second dividing roller portions 111 and the first non-belt roller portions 105.
The two third discharge rollers 95c are provided close to the +X side of the −Y side with respect to the first discharge roller 95a, that is, of the +X side of the second discharge roller 95b and rotate to follow the first discharge roller 95a. The two third discharge rollers 95c are provided at positions in the Z directions corresponding to the second pulley portions 109 provided distributed into two pairs in the Z directions. Each of the third discharge rollers 95c is provided with a third discharge roller shaft 113 extending in the Z directions and one pair of the third pulley portions 115 formed in substantially circular plate shapes. The third discharge roller shaft 113 is supported by the movable holder 93 to be capable of rotating. The third pulley portions 115 are fixed to the third discharge roller shaft 113 and rotate integrally with the third discharge roller shaft 113. The discharge belts 97 span the spaces between the third pulley portions 115 and second pulley portions 109.
The discharge belts 97 span the spaces between the second pulley portions 109 and the third pulley portions 115 and follow the first discharge roller 95a to run between the second pulley portions 109 and the third pulley portions 115. The discharge belts 97 are configured by a material having high friction properties and elasticity such as rubber, for example. The discharge belts 97 are provided at positions corresponding to the first belt roller portions 103 in the Z directions. In other words, the four discharge belts 97 are provided distributed into two pairs in the Z directions. The four discharge belts 97 are provided to run approximately parallel to an XY plane. The discharge belts 97 pinch the tape 213 between the discharge belts 97 and the first belt roller portion 103.
As described above, the movable holder 93 which supports the second discharge roller 95b and the third discharge rollers 95c is pushed toward the +Y side, that is, toward the first discharge roller 95a by the pinching spring 67. The discharge belts 97 support first belt roller portions 103 and the tape 213 in a range between the +Y side of the second pulley portions 109 and the +Y side of the third pulley portions 115 as viewed from the Z direction. Therefore, the +Y sides of the discharge belts 97 flex in a concave arc-shape to conform to the outer peripheral surfaces of the first belt roller portions 103. A range in which the tape 213 is pinched between the first belt roller portions 103 and the discharge belts 97 in the tape feeding direction, that is, the X directions in which the tape 213 is fed is referred to as a pinching range A. In the pinching range A, when the tape 213 is not present between the first belt roller portions 103 and the discharge belts 97, the first belt roller portions 103 and the discharge belts 97 are in contact with each other.
In the discharge feeding section 43 configured in this manner, when the feed motor 153 or the discharge motor 37 operates and the first discharge roller 95a rotates, the second discharge roller 95b and the third discharge rollers 95c rotate following the first discharge roller 95a and the discharge belts 97 run. Accordingly, the tape 213 which is pinched between the first belt roller portions 103 and the discharge belts 97 and between the first non-belt roller portions 105 and the second dividing roller portions 111 is fed toward the tape discharge port 19.
A plurality of types of the tape cartridge 201 are prepared to have different widths of the tape 213, different feeding positions of the tape 213, or the like. Regardless of which tape 213 of which tape cartridge 201 is used, the tape 213 is at least pinched between the pair of first belt roller portions 103 and the pair of discharge belts 97 of the +Z side or between the pair of first belt roller portions 103 and the pair of discharge belts 97 of the −Z side. In other words, due to the two sets of the first belt roller portions 103 and the two sets of the discharge belts 97 being provided distributed between two locations in the Z directions, it is possible to handle differences in the width and differences in the feeding position in the Z directions of the tape 213. The interval of the pair of first belt roller portions 103 in each set and the interval of the pair of discharge belts 97 in each set are narrower than the width of the tape 213 having the narrowest width. Therefore, even the tape 213 having the narrowest width is pinched between the pair of first belt roller portions 103 and the pair of discharge belts 97.
The tape detection mechanism 45 detects the presence or absence of the tape 213 between the discharge rollers 95, that is, between the first discharge roller 95a, the second discharge roller 95b, and the third discharge rollers 95c. The tape detection mechanism 45 is provided with a pivoting section 117 and an discharge sensor 119.
The pivoting section 117 pivots about the third discharge roller shaft 113 as the tape 213, which is fed thereto, comes into contact with the pivoting section 117. As illustrated in
As illustrated in
The two roller shaft insertion portions 129 both protrude to the +Y side from both end portions of the connection portion 127 in the Z directions. One of the roller shaft insertion portions 129 is positioned between the pair of third pulley portions 115 provided on the third discharge roller 95c of the +Z side and the other of the roller shaft insertion portions 129 is positioned between the pair of third pulley portions 115 provided on the third discharge roller 95c of the −Z side.
As illustrated in
Due to the two tape contact portions 139 being provided distributed between two locations in the Z directions in the same manner as the two sets of the first belt roller portions 103 and the two sets of the discharge belts 97, it is possible to handle differences in the width and differences in the feeding position in the Z directions of the tape 213. The first pivoting member 121 pivots if the tape 213 comes into contact with at least one of the two tape contact portions 139.
The two pivot linking portions 131 are provided to protrude to the −Y side from a substantially middle portion in the Z directions of the connection portion 127 and are in close proximity to each other in the Z directions. The second pivoting member 123 is joined to the two pivot linking portions 131 to be capable of pivoting such that the end portion of the +Y side of the second pivoting member 123 is interposed between the two pivot linking portions 131. Each of the two pivot linking portions 131 is provided with a pivot linking hole 141 into which a pivot linking shaft 145 (described later) fits. A spring mounting protrusion portion 143 is provided on the pivot linking portion 131 of the +Z side to protrude in a substantially columnar shape to the +Z side. The pivoting spring 125 is mounted to the spring mounting protrusion portion 143. The pivot restriction portion 133 protrudes to the −Y side along the edge portion of the connection portion 127 of the −X side. As described later, the end portion of the +Y side of the second pivoting member 123 comes into contact with the pivot restriction portion 133.
As illustrated in
The pivoting spring 125 is mounted on the spring mounting protrusion portion 143, one end is locked to the holder-side spring locking portion 99 (refer to
As illustrated in
As illustrated in
As the printing process is started and the tape 213, which is fed from the tape cartridge 201, comes into contact with the tape contact portion 139, the first pivoting member 121 and the second pivoting member 123 rotate integrally in the first pivoting direction 117a against the pivoting spring 125 about the third discharge roller shaft 113 from the state illustrated in
When the thickness of the tape 213 is comparatively thin, the tape 213 is fed still in the state illustrated in
Due to the pivoting spring 125 being provided on the pivot linking portions 131, the direction in which the second pivoting member 123 pivots and the direction of the load placed on the second pivoting member 123 by the pivoting spring 125 approximately match. Therefore, fluctuations in the magnitude of the load placed on the second pivoting member 123 by the pivoting spring 125 are suppressed. Accordingly, it is possible to cause the second pivoting member 123 to smoothly pivot in the second pivoting direction 117b against the pivoting spring 125 after the second pivoting member 123 comes into contact with the pivoting contact section 69.
When the tape 213 passes between the discharge rollers 95 from the state illustrated in
The first pivoting member 121 pivots in the second pivoting direction 117b until the pivoting recessed portions 137 come into contact with the second discharge roller shaft 107. In other words, the second discharge roller shaft 107 restricts the range in which the first pivoting member 121 pivots in the second pivoting direction 117b. The second pivoting member 123 pivots in the first pivoting direction 117a until the end portion of the +Y side of the second pivoting member 123 comes into contact with the pivot restriction portion 133. In other words, the pivot restriction portion 133 restricts the range in which the second pivoting member 123 pivots in the first pivoting direction 117a.
As described above, according to the tape printing apparatus 1 of the present embodiment, due to the tape 213 being pinched between the first belt roller portions 103 and the discharge belts 97, the tape 213 is pinched over a wider range in the length directions of the tape 213 as compared to the tape 213 being pinched between the first non-belt roller portions 105 and the second dividing roller portions 111. Accordingly, since the tape 213 is firmly pinched, the deformation of the tape 213 is suppressed by the tape contact portion 139 of the first pivoting member 121 to which the force of the pivoting spring 125 is applied in the second pivoting direction 117b. Therefore, when the tape 213 is present between the first belt roller portions 103 and the discharge belts 97, it is possible to cause the first pivoting member 121 to pivot appropriately in the first pivoting direction 117a against the pivoting spring 125 and it is possible to suppress the erroneous detection of the tape 213 not being present between the first belt roller portions 103 and the discharge belts 97. Since the pinching range A widens in the tape feeding direction as compared to a configuration in which the tape 213 is pinched between one roller and another, even if the position of the tape contact portion 139 shifts a little in the tape feeding direction, it is possible to cause the tape contact portion 139 to contact the tape 213 within the pinching range A. Accordingly, it is possible to appropriately detect the presence or absence of the tape 213 within the pinching range A, that is, whether or not the tape 213 is discharged when the discharge rollers 95 are caused to rotate.
According to the tape printing apparatus 1 of the present embodiment, due to the first pivoting member 121 and the second pivoting member 123 being interlocked with each other to be capable of pivoting, it is possible to reduce the pivoting amount of the second pivoting member 123 about the third discharge roller shaft 113 as compared to the pivoting amount of the first pivoting member 121 about the third discharge roller shaft 113. Therefore, even when the thickness of the tape 213 which is fed is thick and the first pivoting member 121 pivots greatly, the pivoting amount of the second pivoting member 123 is suppressed. Therefore, it is not necessary to secure a large space for the second pivoting member 123 to pivot and it is possible to reduce the size of the tape discharge unit 33.
Configuration between Print Head and Tape Output Port
As illustrated in
The feed motor 153 is the drive source of the platen roller 205. As described above, the feed motor 153 is also the drive source of the discharge rollers 95. The full cutter 155 is provided with a movable blade 163 and a fixed blade 165 and performs a full cut of the tape 213, that is, cuts both the printing tape 221 and the peeling tape 223 due to the movable blade 163 cutting into the fixed blade 165.
The half cutter 157 performs a half cut on the tape 213, that is, cuts the printing tape 221 without cutting the peeling tape 223. A cut 225 (refer to
The cutter motor 159 is the drive source of the full cutter 155 and the half cutter 157. The cutter motor 159 separately drives the full cutter 155 and the half cutter 157 by changing the rotation direction, for example. Here, the rotation direction of the cutter motor 159 which drives the full cutter 155 will be referred to as a full direction and the rotation direction of the cutter motor 159 which drives the half cutter 157 will be referred to as a half direction. The tape printing apparatus 1 may be configured to separately include a motor that drives the full cutter 155 and a motor that drives the half cutter 157.
The control section 161 performs overall control of various parts of the tape printing apparatus 1 such as the feed motor 153, the cutter motor 159, and the discharge motor 37. The control section 161 is provided with a processor 171 represented by a central processing unit (CPU) and various kinds of memory such as random access memory 173 (RAM) and read only memory 175 (ROM). The processor 171 reads a control program stored in the ROM 175 and executes the control program using the RAM 173.
Here, for example, when the specification such as the thickness or the material of the tape 213 is different from that of a genuine product, there is a concern that the half cutter 157 may cut not only the printing tape 221 but also the peeling tape 223. Therefore, during the printing, the control section 161 executes the print control process described hereinafter. Hereinafter, both the printing tape 221 and the peeling tape 223 being cut by the half cutter 157 will be referred to as miscutting of the tape 213.
Print Control Process
A description will be given of the print control process which is executed by the control section 161 during the printing based on
First, when the control section 161 receives a print execution command from the keyboard 29 or the like, the control section 161 drives the feed motor 153 and the print head 15. Accordingly, the platen roller 205 and the discharge rollers 95 rotate, the tape 213 is fed, the print head 15 emits heat, and the printing starts. When the tape 213 which is fed comes into contact with the tape contact portion 139, the discharge sensor 119 outputs the High signal.
Next, when the half cut location of the tape 213 reaches the half cutter 157, the control section 161 stops the driving of the feed motor 153 and the print head 15. Accordingly, since the rotation of the platen roller 205 and the discharge rollers 95 stops, the feeding of the tape 213 stops, and the print head 15 stops emitting heat, the printing is canceled.
Next, the control section 161 drives the cutter motor 159 in the half direction. Accordingly, the half cutter 157 performs the blade closing operation. here, it is assumed that the tape 213 is not miscut and the half cutting is performed appropriately.
After driving the cutter motor 159 a predetermined amount, the control section 161 stops the driving of the cutter motor 159, and after a predetermined time elapses, the control section 161 drives the cutter motor 159 in the half direction again. Accordingly, the half cutter 157 performs the blade opening operation. At this time, the control section 161 drives the discharge motor 37. Accordingly, the discharge rollers 95 rotate without the platen roller 205 rotating. Here, since the tape 213 is not miscut by the half cutter 157 and the tape 213 is continuous between the discharge rollers 95 and the platen roller 205, even if the discharge rollers 95 rotate, the tape 213 pinched between the platen roller 205 and the print head 15 is not discharged from the tape discharge port 19. Therefore, the detection signal of the discharge sensor 119 remains the High signal.
After driving the cutter motor 159 by a predetermined amount, the control section 161 stops the driving of the cutter motor 159 and the discharge motor 37. When the detection signal from the discharge sensor 119 remains the High signal while the control section 161 drives the cutter motor 159 and the discharge motor 37, the control section 161 determines that the tape 213 is not miscut by the half cutter 157, and after stopping the driving of the cutter motor 159 and the discharge motor 37, drives the feed motor 153 and the print head 15 and restarts the printing. When all of the printing is completed, although not illustrated in
Meanwhile, a description will be given of a case in which the tape 213 is miscut when the half cutter 157 performs the blade closing operation based on
When the detection signal of the discharge sensor 119 switches to the Low signal during the driving of the cutter motor 159 and the discharge motor 37, the control section 161 determines that the tape 213 is miscut by the half cutter 157. In this case, after stopping the driving of the cutter motor 159 and the discharge motor 37, instead of restarting the printing, the control section 161 drives the feed motor 153 in order to discharge the printed portion of the tape 213 which is printed part way. Once the rear end of the printed portion of the tape 213 reaches the full cutter 155, the control section 161 stops the driving of the feed motor 153 and drives the cutter motor 159 in the full direction. Accordingly, the full cutter 155 cuts the tape 213. Next, the control section 161 drives the discharge motor 37. Accordingly, the printed portion of the tape 213 which is cut off is discharged from the tape discharge port 19.
When the control section 161 determines that the tape 213 is miscut by the half cutter 157, the control section 161 may end the print control process without driving the feed motor 153, the cutter motor 159, and the discharge motor 37. When the control section 161 determines that the tape 213 is miscut by the half cutter 157, the control section 161 may cause a notification section such as the display 31 to perform an error notification that the half cutting was not performed appropriately.
As described above, according to the tape printing apparatus 1 of the present embodiment, due to the discharge rollers 95 rotating during the blade opening operation of the half cutter 157, when the tape 213 is not miscut by the half cutter 157, the tape 213 is not discharged, and when the tape 213 is miscut by the half cutter 157, the tape 213 which is cut off is discharged. Therefore, different detection signals are output by the discharge sensor 119 between a case in which the tape 213 is not miscut by the half cutter 157 and a case in which the tape 213 is miscut by the half cutter 157. Therefore, it is possible to detect whether or not the tape 213 is miscut by the half cutter 157. When it is detected that the tape 213 is miscut by the half cutter 157, it is possible to perform adjustment such as weakening the cut-in force of the cutting blade 167 with respect to the blade receiving member 169, for example. Accordingly, it is possible to suppress the tape 213 being miscut again during the next blade closing operation.
The present disclosure is not limited to the embodiment described above, and it goes without saying that various configurations may be adopted within a scope that does not depart from the gist of the present disclosure. For example, in addition to the above description, the embodiment may be modified in the following modes.
The configuration is not limited to one in which the tape detection mechanism 45 is provided in the tape discharge unit 33 and may be a configuration in which the tape detection mechanism 45 is provided between the print head 15 and the full cutter 155, for example. In other words, a configuration may be adopted in which the tape detection mechanism 45 detects the presence or absence of the tape 213 between the print head 15 and the full cutter 155, for example.
Instead of the pivoting spring 125, a configuration may be adopted including two elastic members, an elastic member which causes the first pivoting member 121 to pivot in the second pivoting direction 117b and an elastic member which causes the second pivoting member 123 to pivot in the first pivoting direction 117a. Naturally, by using the single pivoting spring 125 as in the embodiment, it is possible to improve the assembling properties of the pivoting section 117 as compared to a configuration provided with two elastic members.
The discharge sensor 119 is not limited to a transmitting type and may be a reflecting type. The discharge sensor 119 is not limited to an optical system and may use a mechanical switch such as a micro-switch, for example. Naturally, by using an optical system as in the embodiment, the sensor applying a load to the pivoting of the first pivoting member 121 and the second pivoting member 123 is suppressed and it is possible to cause the first pivoting member 121 and the second pivoting member 123 to pivot smoothly.
The first pivoting member 121 is not limited to a configuration in which the first pivoting member 121 pivots about the third discharge roller shaft 113 and may be configured to pivot about the second discharge roller shaft 107, for example.
The discharge rollers 95 are not limited to a configuration in which the discharge rollers 95 rotate during the blade opening operation of the half cutter 157 and may be configured to rotate after the start of the blade opening operation and before the start of the rotation of the platen roller 205. Even in this configuration, it is possible to detect the presence or absence of miscutting by the half cutter 157 before restarting the printing. Naturally, due to the discharge rollers 95 rotating during the blade opening operation of the half cutter 157 as in the embodiment, it is possible to immediately restart the printing after the completion of the blade opening operation.
The cartridge mounting portion 7 is not limited to a configuration in which the tape cartridge 201 or the ribbon cartridge is selectively mounted to the cartridge mounting portion 7, and may be configured such that only the tape cartridge 201 is mounted or configured such that only the ribbon cartridge is mounted. The tape 213 is not limited to a configuration in which the tape 213 is supplied from the tape cartridge 201 mounted to the cartridge mounting portion 7 and may be configured to be supplied from outside of the tape printing apparatus 1 as in the case of the ribbon cartridge being mounted.
A configuration may be adopted in which the embodiment and modification examples are combined with each other.
Hereinafter, an appendix will be given relating to the tape detection mechanism and the tape printing apparatus.
A tape detection mechanism includes a first pivoting member provided to pivot about a detection pivoting shaft, a second pivoting member pivotally linked to a pivot linking portion provided on the first pivoting member, a pivoting contact section with which the second pivoting member comes into contact when the first pivoting member and the second pivoting member pivot in a first pivoting direction about the detection pivoting shaft as the tape, which is fed thereto, comes into contact with the first pivoting member, and a sensor which detects the second pivoting member which comes into contact with the pivoting contact section.
In this configuration, due to the first pivoting member and the second pivoting member being interlocked with each other to be capable of pivoting, it is possible to reduce the pivoting amount of the second pivoting member about the detection pivoting shaft as compared to the pivoting amount of the first pivoting member about the detection pivoting shaft. Therefore, even when the thickness of the tape which is fed is thick and the first pivoting member pivots greatly, the pivoting amount of the second pivoting member is suppressed. Therefore, it is not necessary to secure a large space for the second pivoting member to pivot and it is possible to reduce the size of the tape detection mechanism.
In this case, it is preferable for the tape detection mechanism to further include a pivoting elastic member which applies a force to the first pivoting member such that the first pivoting member pivots in a second pivoting direction which is an opposite direction from the first pivoting direction about the detection pivoting shaft and applies a force to the second pivoting member such that the second pivoting member pivots in the first pivoting direction about the pivot linking portion.
In this configuration, after the tape passes through, it is possible to cause the first pivoting member to pivot in the second pivoting direction about the detection pivoting shaft and to cause the second pivoting member to pivot in the second pivoting direction about the pivot linking portion. Since it is not necessary to provide the two elastic members of the elastic member which applies a force to the first pivoting member in the second pivoting direction and the elastic member which applies a force to the second pivoting member in the first pivoting direction, it is possible to improve the assembling properties.
In this case, it is preferable for a pivot restriction portion which restricts a range in which the second pivoting member pivots to the first pivoting direction to be provided on the first pivoting member.
In this configuration, after the tape passes through, it is possible to cause the second pivoting member which pivots in the first pivoting direction to pivot to an appropriate position.
In this case, it is preferable for the pivoting elastic member to be provided on the pivot linking portion.
In this configuration, after the second pivoting member comes into contact with the pivoting contact section, when the second pivoting member pivots in the second pivoting direction with respect to the first pivoting member, fluctuations in the magnitude of the load applied to the second pivoting member by the pivoting elastic member are suppressed. Accordingly, it is possible to cause the second pivoting member to smoothly pivot in the second pivoting direction against the pivoting elastic member after the second pivoting member comes into contact with the pivoting contact section.
In this case, it is preferable for the sensor to use an optical system.
In this configuration, the sensor applying a load to the pivoting of the first pivoting member and the second pivoting member is suppressed and it is possible to cause the first pivoting member and the second pivoting member to pivot smoothly.
A tape printing apparatus including a first pivoting member provided to pivot about a detection pivoting shaft, a second pivoting member pivotally linked to a pivot linking portion provided on the first pivoting member, a pivoting contact section with which the second pivoting member comes into contact when the first pivoting member and the second pivoting member pivot in a first pivoting direction about the detection pivoting shaft as the tape, which is fed thereto, comes into contact with the first pivoting member, a sensor which detects the second pivoting member which comes into contact with the pivoting contact section, and a print head which performs printing on the tape.
In this configuration, due to the first pivoting member and the second pivoting member being interlocked with each other to be capable of pivoting, it is possible to reduce the pivoting amount of the second pivoting member about the detection pivoting shaft as compared to the pivoting amount of the first pivoting member about the detection pivoting shaft. Therefore, even when the thickness of the tape which is fed is thick and the first pivoting member pivots greatly, the pivoting amount of the second pivoting member is suppressed. Therefore, it is not necessary to secure a large space for the second pivoting member to pivot and it is possible to reduce the size of the tape detection mechanism.
