  Hereinafter, an embodiment of the present invention will be mainly described with reference to the accompanying drawings. The front-back, left-right, and up-down directions in the following description are based on the directions of arrows in the drawings. The directions of the arrows are aligned with each other in the different drawings. In some drawings, for convenience of illustration, a part of the configuration of the pressure-sensitive adhesive transfer mechanism 10 and the printer 1 according to the embodiment and the illustration of the paper P are omitted.

  FIG. 1 is an external perspective view of a printer 1 having an adhesive transfer mechanism 10 according to one embodiment. FIG. 2 is a side view of the printer 1 of FIG. In FIG. 1 and FIG. 2, illustration of a later-described roll paper R in which a long paper P is wound in a roll shape is omitted for simplicity of description.

  The printer 1 according to one embodiment stores a roll paper R in which a long paper P is wound in a roll shape. The printer 1 performs printing on the paper P while pulling out and transporting the paper P from the stored roll paper R. The printer 1 cuts the printed paper P at a predetermined timing. The printer 1 has an adhesive transfer mechanism 10 according to one embodiment, and transfers the adhesive to a transfer surface, which is a surface opposite to a print surface of the paper P, by the adhesive transfer mechanism 10.

  As shown in FIGS. 1 and 2, the printer 1 includes a housing 1a that forms an outer frame, and a cover 1b attached to a front portion on the upper surface side of the housing 1a. The printer 1 has a paper discharge unit 1c that discharges the paper P and that opens forward under the cover 1b. The printer 1 has, as major components, an adhesive transfer mechanism 10 that forms the front side of the printer 1 and a paper transport mechanism 20 that forms the rear side of the printer 1.

  The paper transport mechanism 20 has a storage unit 21 that stores a roll paper R in which a long paper P is wound in a roll shape. As shown in FIGS. 1 and 2, the storage unit 21 is formed on the entire rear part of the paper transport mechanism 20 and includes a space capable of storing a roll paper R in which a long paper P is wound in a roll shape. The paper P pulled out from the storage section 21 is transported by the paper transport mechanism 20 and reaches the front and rear positions where the adhesive transfer mechanism 10 is installed. The pressure-sensitive adhesive transfer mechanism 10 transfers the pressure-sensitive adhesive to the transfer surface of the sheet P that has reached the front / rear position as necessary. Thereafter, the printer 1 discharges the paper P cut by the paper transport mechanism 20 from the paper discharge unit 1c.

  FIG. 3 is a side view illustrating the pressure-sensitive adhesive transfer mechanism 10 and the sheet transport mechanism 20 according to the embodiment. 3 omits illustration of the housing 1a and the cover 1b of the printer 1 and omits the main components of the adhesive transfer mechanism 10 and the paper transport mechanism 20 for the sake of simplicity. FIG. 3 shows a state where the roll paper R is stored in the storage unit 21. As illustrated in FIG. 3, a path connecting the storage unit 21 and the paper discharge unit 1 c is a conveyance path of the paper P, and a direction from the storage unit 21 to the paper discharge unit 1 c corresponds to a conveyance direction of the paper P. In the following description, the transport path of the paper P is simply referred to as a transport path, and the transport direction of the paper P is simply referred to as a transport direction. In the transport path, the roll paper R accommodated in the accommodating section 21 is on the upstream side, and the paper discharge section 1c is on the downstream side.

  In the paper transport mechanism 20, a decurling unit 22, a printing unit 23, and a cutting unit 24 are arranged in order from the roll paper R stored in the storage unit 21 toward the downstream side of the transport path. The paper P conveyed along the conveyance path corrects the curl of the paper P by the decurling unit 22, prints on the printing surface P1 of the paper P by the printing unit 23, and prints the paper P by the cutting unit 24. Is disconnected. Here, the printing surface P1 of the paper P includes, for example, the upper surface of the paper P. At this time, the transfer surface P2 of the sheet P includes, for example, the lower surface of the sheet P.

  The decurling unit 22 corrects the curl of the sheet P immediately after being pulled out from the storage unit 21. The roll paper R is formed by winding a long paper P in a roll shape, and the paper P drawn from the roll paper R has a curl. Due to this curl, the paper P curls with the transfer surface P2 on which the adhesive is to be transferred inside, and after the paper P is discharged from the paper discharge unit 1c, the transfer surface P2 of the paper P is located on the front side of the housing 1a of the printer 1. May stick to the exterior surface. Further, the adhesive transferred to the paper P may adhere to another portion of the transfer surface P2 of the rolled paper P. To avoid these cases, the paper transport mechanism 20 has a decurling unit 22 that corrects the curl of the paper P.

  The decurling unit 22 has a decurling member 22a and a pressing member 22b. The decurling member 22a is located above the sheet P, and the pressing member 22b is located below the sheet P. The sheet P passes while bending between these members while being in contact with the decurling member 22a and the pressing member 22b from the upper surface side and the lower surface side, respectively.

  More specifically, the decurling member 22a has a plate-shaped main body 22a1, an ironing portion 22a2 formed at the leading end of the main body 22a1 on the paper P side, and a spring 22a3. The ironing portion 22a2 is formed of, for example, a metal shaft. The spring 22a3 urges a portion of the main body 22a1 on the downstream side of the transport path obliquely downward in the drawing. As a result, the sheet P is bent at a portion in contact with the ironing portion 22a2. When the sheet P passes through the squeezing section 22a2 in a bent state, the sheet P is squeezed by the squeezing section 22a2, and the curl of the sheet P is corrected.

  The pressing member 22b presses the sheet P from the lower surface side of the sheet P on the upstream side of the transport path from the portion where the sheet P comes into contact with the ironing portion 22a2. Thereby, the bending angle of the sheet P at the portion in contact with the ironing portion 22a2 is reduced, and the curl of the sheet P is corrected with a larger force.

  The decurling unit 22 is not limited to the above-described configuration, and may have any configuration that can correct the curl of the sheet P immediately after being pulled out from the storage unit 21. Further, in the case where the curl of the paper P is small or has no curl, or in the case where it is not necessary to correct the curl even if the curl is present, the decurling unit 22 It does not have to be arranged.

  The printing unit 23 prints on the printing surface P1 of the paper P conveyed from the decurling unit 22. The printing unit 23 has a platen roller 23a and a print head 23b. The print head 23b is located above the paper P, and the platen roller 23a is located below the paper P. The paper P pulled out from the roll paper R and passed through the decurling unit 22 is sandwiched between the platen roller 23a and the print head 23b. The platen roller 23a is rotated by a stepping motor (not shown). In FIG. 3, when the platen roller 23a rotates counterclockwise, the paper P is pulled out from the roll paper R, and the pulled out paper P is transported downstream along the transport path. The print head 23b has a plurality of heating elements arranged in the width direction of the paper P orthogonal to the transport direction, and prints on the print surface P1 of the paper P.

  As described above, the printing unit 23 prints on the printing surface P1 of the paper P based on, for example, the thermal method. The configuration of the printing unit 23 is not limited to this. The printing unit 23 may perform printing on the printing surface P1 of the paper P based on any printing method other than the thermal method.

  The cutting unit 24 cuts the sheet P conveyed from the printing unit 23 at a predetermined timing. The cutting section 24 has a frame 24a, a motor 24b attached to the rear of the frame 24a, and a movable blade 24c attached to the front of the frame 24a. The cutting unit 24 cuts the paper P by reciprocating the movable blade 24c vertically with respect to the frame 24a by the motor 24b.

  In the printer 1, the sheet P is transported and held by the platen roller 23a of the printing unit 23. The printer 1 does not have a mechanism for holding the sheet P while the sheet P is being conveyed downstream of the printing unit 23. Therefore, the size of the printer 1 is reduced, and the cost is reduced.

  The adhesive transfer mechanism 10 transfers the adhesive to the transfer surface P2 of the paper P transported from the paper transport mechanism 20. At this time, the paper transport mechanism 20 stops transporting the paper P. Hereinafter, the configuration and function of the adhesive transfer mechanism 10 will be mainly described.

  FIG. 4 is a perspective view showing a part of the configuration of the printer 1 including the adhesive transfer mechanism 10 of FIG. In FIG. 4, for simplicity of description, the illustration of a front frame constituting the front surface of the pressure-sensitive adhesive transfer mechanism 10 is omitted, and main components of the pressure-sensitive adhesive transfer mechanism 10 are illustrated.

  As shown in FIG. 4, the adhesive transfer mechanism 10 includes, as major components, an adhesive cartridge 11, a driving unit 12, a transfer load adjusting unit 13, a pressing member 14, a pressing member adjusting unit 15, a transfer platen 16.

  FIG. 5 is a front view showing a state where the adhesive cartridge 11 included in the adhesive transfer mechanism 10 of FIG. 4 is attached to the frame 11a.

  As shown in FIG. 5, the adhesive cartridge 11 is attached to a frame 11a having a guide hole 11a1 extending linearly. The frame 11a has, in addition to the guide hole 11a1, a pin 11a2 that protrudes from the front surface toward the drive unit 12 side. The pin 11a2 corresponds to a second pin described in the claims.

  FIG. 6 is an internal structural diagram showing the inside of the adhesive cartridge 11 of FIG. 6, the front surface of the casing 11b of the adhesive cartridge 11 and the frame 11a are omitted for the sake of simplicity, and the internal structure of the adhesive cartridge 11 is mainly shown.

  As shown in FIG. 6, the adhesive cartridge 11 includes an adhesive tape T indicated by a solid line, a casing 11b, a pay-out reel 11c, a take-up reel 11d, and two interlocking gears 11f housed in the casing 11b. Have. The adhesive cartridge 11 further has a transfer portion 11g that supports a transfer roller 11g1 protruding upward from the casing 11b at its tip. The transfer roller 11g1 is rotatably supported at the tip of the transfer unit 11g. The transfer unit 11g presses the transported paper P to transfer the adhesive onto the paper P.

  The payout reel 11c pays out the adhesive tape T by rotating counterclockwise in FIG. The take-up reel 11d takes up the adhesive tape T after the adhesive is transferred onto the paper P by rotating clockwise in FIG. The feeding reel 11c has teeth 11c1 on its outer peripheral portion. The take-up reel 11d has a gear 11d1 formed so as to protrude one step forward from the front surface thereof. The two interlocking gears 11f mesh with the teeth 11c1 of the take-out reel 11c and the gear 11d1 of the take-up reel 11d, respectively, so as to interlock the take-up reel 11c and the take-up reel 11d. When the feeding reel 11c rotates, the take-up reel 11d also rotates by the two interlocking gears 11f.

  The adhesive tape T fed from the feeding reel 11c is wound around a transfer roller 11g1, passes through the transfer roller 11g1, and is wound on a take-up reel 11d. The adhesive tape T is wound around the transfer roller 11g1 so as to be substantially symmetric with respect to the center axis L of the transfer portion 11g passing through the center of the transfer roller 11g1 in a front view as shown in FIG. An adhesive is applied to one surface of the adhesive tape T, and the transfer roller 11g1 is pressed against the paper P, so that the adhesive tape T wound around the transfer roller 11g1 The adhesive is transferred.

  FIG. 7 is an enlarged sectional view of the pressure-sensitive adhesive cartridge 11 taken along the line VII-VII of FIG.

  As shown in FIGS. 6 and 7, the transfer section 11g of the adhesive cartridge 11 has a space 11g2 penetrating in the front-rear direction below the transfer roller 11g1. The transfer unit 11g is accommodated in the space 11g2, and is supported by a support unit 11b1 formed integrally with the casing 11b. More specifically, the support portion 11b1 has a raised portion 11b2 that is substantially triangular in cross-sectional view, which is raised in a mountain shape, at a substantially central portion of the upper surface in the front-rear direction. The raised portion 11b2 is formed in a tapered shape in a cross-sectional view, and the transfer portion 11g is supported by the tip of the tapered raised portion 11b2. The transfer portion 11g is attached to the adhesive cartridge 11 based on the contact with the raised portion 11b2.

  Such a centering mechanism including the space 11g2 of the transfer portion 11g, the support portion 11b1, the raised portion 11b2, and the like improves the transfer performance of the transfer roller 11g1. For example, even if the adhesive cartridge 11 is inclined in the front-rear direction with respect to the sheet P, the transfer roller 11g1 is entirely parallel to the sheet P in the front-rear direction with the transfer roller 11g1 being parallel to the sheet P by the centering mechanism. Contact As a result, the adhesive tape T wound around the transfer roller 11g1 is entirely in contact with the paper P in the front-rear direction, so that the adhesive is transferred to the paper P without leakage in the front-rear direction.

  Referring to FIG. 4 again, the drive unit 12 includes a motor 12a, a worm gear 12b directly driven by the motor 12a, a worm wheel 12c meshing with the worm gear 12b, two interlocking gears 12d, and a cam gear 12e. . In the drive unit 12, the driving force from the motor 12a is transmitted to the cam gear 12e via the worm gear 12b, the worm wheel 12c, and the two interlocking gears 12d. The cam gear 12e rotates clockwise about the shaft 12f. A plurality of cams described below are arranged on the shaft 12f in addition to the cam gear 12e so as to overlap in the front-rear direction. When the cam gear 12e rotates clockwise, these cams also rotate clockwise about the shaft 12f in conjunction with the cam gear 12e.

  8A and 8B are component diagrams mainly showing a plurality of components forming a coaxial structure with the cam gear 12e. FIG. 8A is a front view of these components, and FIG. 8B is a side view of these components.

  As shown in FIGS. 8A and 8B, the drive plate 12 g 1 and the cartridge drive cam 12 g of the drive unit 12, the transfer load adjustment cam 13 a of the transfer load adjustment unit 13, and the drive unit 12 are sequentially arranged from the rear to the front along the shaft 12 f. , A cam gear 12e of the driving unit 12, and a pressing member driving cam 15a of the pressing member adjusting unit 15. The drive unit 12 projects from the cartridge drive cam 12g toward the adhesive cartridge 11 side while penetrating the drive plate 12g1 at a position separated from the rotation center C of the cartridge drive cam 12g in the outer peripheral direction, and engages with the guide hole 11a1 of the frame 11a. It further has a pin 12h. The pin 12h corresponds to a first pin described in the claims. When the cartridge driving cam 12g rotates clockwise in conjunction with the cam gear 12e, the pin 12h makes a circular motion clockwise while maintaining a fixed distance from the shaft 12f.

  The sensor cam 12i of the drive unit 12 is detected by a sensor 12j of the drive unit 12 illustrated in FIG. The sensor 12j detects the rotation position and the like of the sensor cam 12i to determine whether or not the plurality of cams and the cam gear 12e disposed on the shaft 12f have started rotating and then made one rotation to return to the original state. Or to detect.

  FIGS. 9A to 9D are schematic diagrams illustrating the movement of the adhesive cartridge 11 realized by the drive unit 12. FIG. FIG. 9A is a schematic diagram illustrating a standby position of the adhesive cartridge 11. FIG. 9B is a schematic diagram illustrating the position of the adhesive cartridge 11 when the adhesive cartridge 11 starts to shift from the retracted state to the transfer state. FIG. 9C is a schematic diagram illustrating the position of the adhesive cartridge 11 when the adhesive cartridge 11 is in the middle of the transfer state. FIG. 9D is a schematic diagram illustrating the position of the adhesive cartridge 11 when the adhesive cartridge 11 starts to shift from the transfer state to the retracted state. 9A to 9D, six marks S1, S2, S3, S4, S5, and S6 shown along the sheet P indicate the position of the transfer roller 11g1 in the main state of the adhesive cartridge 11, By sequentially connecting the marks S1 to S6, the locus of the transfer roller 11g1 is shown.

  As shown in FIG. 9A, when the adhesive cartridge 11 is at the standby position, the transfer roller 11g1 is at the position of the mark S1. At this time, the angle of the transfer unit 11g with respect to the sheet P is an acute angle. The angle of the transfer unit 11g with respect to the sheet P includes an angle at which the central axis L of the transfer unit 11g and the sheet P intersect in a front view of the adhesive cartridge 11 viewed from the transport direction as illustrated in FIG. 9A. When the adhesive cartridge 11 has a shape as shown in FIG. 9A, the entire adhesive cartridge 11 is substantially orthogonal to the paper P. That is, the angle of the adhesive cartridge 11 with respect to the sheet P is approximately 90 °. When the adhesive is transferred to the transfer surface P2 of the transported paper P, as shown in FIGS. 9A to 9D, the driving unit 12 controls the adhesive so that the transfer unit 11g moves in a direction intersecting the transport direction of the paper P. The cartridge 11 is driven. Here, the direction that intersects the transport direction includes a direction that is orthogonal to the transport direction of the sheet P, and a direction that approximates the direction.

  The drive unit 12 includes a transfer state in which the transfer unit 11g presses the sheet P to transfer the adhesive to the sheet P, and a transfer state in which the transfer unit 11g separates from the sheet P and the adhesive is not transferred to the sheet P. The adhesive cartridge 11 is shifted between the positions. For example, in FIGS. 9A to 9D, when the transfer roller 11g1 is positioned at the marks S3, S4, and S5, the adhesive cartridge 11 is in the transfer state. On the other hand, in FIGS. 9A to 9D, when the transfer roller 11g1 is positioned at the marks S1, S2, and S6, the adhesive cartridge 11 is in a retracted state.

  As shown in FIG. 9B, when the adhesive cartridge 11 starts to shift from the retracted state to the transfer state, the transfer unit 11g is inclined by the first angle θ1 with respect to the sheet P. The first angle θ1 of the transfer unit 11g with respect to the sheet P is smaller than the angle of the transfer unit 11g with respect to the sheet P when the adhesive cartridge 11 is at the standby position. The first angle θ1 is, for example, an acute angle. The adhesive cartridge 11 is inclined such that the transfer roller 11g1 is located on the left side of the rotation center C of the cartridge driving cam 12g. That is, the pressure-sensitive adhesive cartridge 11 starts moving from the position corresponding to the mark S1, which is the standby position of the transfer roller 11g1, by the driving of the drive unit 12, and moves to the mark S3 via the position corresponding to the mark S2. The transfer unit 11g contacts the sheet P in a state where the transfer unit 11g is inclined by the first angle θ1 at the position where the transfer is performed.

  As shown in FIG. 9C, when the adhesive cartridge 11 is in the transfer state, the transfer roller 11g1 moves linearly along the transfer surface P2 of the sheet P in a direction intersecting the transport direction of the sheet P. Here, if the sheet P and the transfer platen 16 are not disposed, the trajectory of the transfer roller 11g1 draws an arc connecting the marks S3 to S5, and the transfer roller 11g1 projects most upward in the middle of the transfer state. As described above, when the adhesive cartridge 11 is in the middle of the transfer state, the adhesive roller 11 is inclined such that the transfer roller 11g1 is located at substantially the same left and right position as the rotation center C of the cartridge drive cam 12g.

  As shown in FIG. 9D, when the adhesive cartridge 11 starts to shift from the transfer state to the retracted state, the transfer unit 11g is inclined with respect to the sheet P by the second angle θ2. The second angle θ2 of the transfer unit 11g with respect to the sheet P when starting to shift from the transfer state to the retracted state is larger than the first angle θ1 of the transfer unit 11g when starting to shift from the retracted state to the transfer state. The second angle θ2 is larger than the angle of the transfer unit 11g with respect to the sheet P when the adhesive cartridge 11 is at the standby position. The second angle θ2 is, for example, an obtuse angle. The adhesive cartridge 11 is inclined such that the transfer roller 11g1 is located on the right side of the rotation center C of the cartridge drive cam 12g. The adhesive cartridge 11 is separated from the sheet P by the driving of the driving unit 12 in a state where the transfer unit 11g is inclined by the second angle θ2 at the position corresponding to the mark S5, and passes through the position corresponding to the mark S6. The transfer roller 11g1 returns to the position corresponding to the mark S1, which is the standby position.

  FIGS. 10A to 10D are schematic diagrams mainly showing components for realizing the movement of the adhesive cartridge 11 among the components shown in FIGS. 9A to 9D, respectively.

  As shown in FIGS. 10A to 10D, the movement of the adhesive cartridge 11 described with reference to FIGS. 9A to 9D is realized mainly based on the cartridge driving cam 12g. The adhesive cartridge 11 and the cartridge driving cam 12g overlap in the front-rear direction, and the rear frame B is disposed between them. A guide hole B1 is formed in the rear frame B. When the guide hole 11a1 of the frame 11a is engaged with the pin 12h projecting from the cartridge driving cam 12g, and the pin 11a2 of the frame 11a is engaged with the guide hole B1 of the rear frame B, the adhesive cartridge 11 is moved to the frame 11a. , And is driven by the cartridge driving cam 12g.

  More specifically, as shown in FIG. 10A, when the adhesive cartridge 11 is at the standby position, the pin 12h protruding from the cartridge driving cam 12g is located near the lower end of the guide hole 11a1 of the frame 11a. Similarly, the pin 11a2 of the frame 11a is located near the lower end of the guide hole B1 of the rear frame B.

  When the cartridge driving cam 12g rotates clockwise from the state shown in FIG. 10A, the adhesive cartridge 11 is driven based on the engagement between the pin 12h and the guide hole 11a1. As shown in FIG. 10B, the pin 12h protruding from the cartridge driving cam 12g moves upward along the guide hole 11a1 of the frame 11a until the adhesive cartridge 11 starts to shift from the retracted state to the transfer state. Similarly, the pin 11a2 of the frame 11a moves upward along the guide hole B1 of the rear frame B.

  As shown in FIG. 10C, when the adhesive cartridge 11 is in the middle of the transfer state, the pin 12h protruding from the cartridge driving cam 12g is located at the upper end of the guide hole 11a1 of the frame 11a. On the other hand, the pins 11a2 of the frame 11a are pushed by the transfer platen 16 and the sheet P from the temporary trajectory of the arc when the transfer platen 16 and the sheet P are not arranged to the transfer surface P2. It descends to the substantially central part of the guide hole B1.

  As shown in FIG. 10D, the pin 12h protruding from the cartridge driving cam 12g moves downward along the guide hole 11a1 of the frame 11a before the adhesive cartridge 11 starts to shift from the middle of the transfer state to the retracted state. I do. On the other hand, the pin 11a2 of the frame 11a moves upward again along the guide hole B1 of the rear frame B.

  Thus, the rotation of the cartridge driving cam 12g causes the pin 12h to reciprocate along the guide hole 11a1. The rotational movement of the cartridge driving cam 12g is converted into a reciprocating movement by the engagement between the pin 12h and the guide hole 11a1, whereby the movement of the adhesive cartridge 11 as shown in FIGS. 10A to 10D is realized.

  FIG. 11A is a schematic diagram conceptually showing a state in which the adhesive A is transferred from the transfer roller 11g1 to the transfer surface P2 of the paper P. FIG. 11B is a schematic view conceptually showing the movement of the transfer roller 11g1 when the adhesive cartridge 11 shifts to the retracted state. FIG. 11C is a schematic diagram conceptually showing a virtual case where the transfer roller 11g1 moves directly below the sheet P as in the related art. In FIGS. 11A to 11C, hatching with oblique lines indicates the adhesive tape T in a state where the adhesive A has not been transferred to the transfer surface P2 of the paper P. The hatching with dots indicates the adhesive A transferred to the transfer surface P2 of the paper P. The unhatched portion shows the adhesive tape T in a state where the adhesive A has been transferred to the transfer surface P2 of the paper P.

  As shown in FIG. 11A, when the adhesive cartridge 11 moves linearly in a direction intersecting the transport direction, the transfer roller 11g1 moves in the transfer direction in the figure while rotating counterclockwise. At this time, when the transfer roller 11g1 presses the paper P, the adhesive A applied to one surface of the adhesive tape T is transferred to the transfer surface P2 of the paper P. The pressure-sensitive adhesive tape T after the transfer of the pressure-sensitive adhesive A is taken up by a take-up reel 11d shown in FIG.

  Here, as shown in FIG. 11C, a virtual case in which the transfer roller 11g1 moves directly below the sheet P as in the related art is considered. When the transfer roller 11g1 stops rotating to move right below the sheet P, the transfer area W1 and the adhesive tape T in which the adhesive A has not been transferred are continuous. In this state, when the transfer roller 11g1 moves right below the sheet P, the moving direction of the adhesive tape T still wound around the transfer roller 11g1 and in a state where the adhesive A is not transferred is changed to the transfer area W1. Is substantially orthogonal to.

  As described above, the pressure-sensitive adhesive A in the area W2 corresponding to about 周 circumference of the transfer roller 11g1, indicated by a pair of parallel two-dot chain lines in FIG. 11C, is peeled off from the pressure-sensitive adhesive tape T. In addition, one end of the adhesive A peeled off from the adhesive tape T adheres to the adhesive tape T wound around the transfer roller 11g1, and the other end of the transfer roller 11g1 adheres to the end of the transfer area W1. By the movement, the stringing in which the pressure-sensitive adhesive A peeled off from the pressure-sensitive adhesive tape T is stretched easily occurs. Thereby, the cutting of the adhesive A becomes worse. Under the same condition that the transfer roller 11g1 moves right below the paper P, such stringing is more likely to occur as the second angle θ2 of the transfer portion 11g of the adhesive cartridge 11 shown in FIG. 9D is smaller. Become. That is, when the transfer roller 11g1 is separated from the paper P, and the locus of the movement and the angle of the paper P are the same, the smaller the second angle θ2, the more the adhesive A peeled off from the adhesive tape T. The amount increases and stringing is more likely to occur. Conversely, as the second angle θ2 is larger, the amount of the adhesive A that is peeled off from the adhesive tape T decreases, and stringing is less likely to occur.

  Since the adhesive A in the area W2 is peeled off from the adhesive tape T, the adhesive tape extends over a wide area from the outer peripheral point closest to the sheet P to the outer peripheral point corresponding to the position of the other end of the area W2 on the transfer roller 11g1. T has no adhesive A. As a result, when the adhesive cartridge 11 returns to the standby position and then starts to shift to the transfer state again, the adhesive tape T on which the adhesive A is not applied contacts the transfer surface P2 of the paper P. Therefore, the pressure-sensitive adhesive cartridge 11 may run idle.

  The pressure-sensitive adhesive transfer mechanism 10 according to one embodiment solves the above problems. For example, as shown in FIG. 11B, when the adhesive cartridge 11 shifts from the transfer state to the retracted state, the drive unit 12 separates the transfer unit 11g diagonally outside the transfer region W1 of the adhesive A on the paper P. The adhesive cartridge 11 is driven in such a manner as to perform the operation. When the transfer roller 11g1 is separated from the transfer area W1 by an angle as shown in FIG. 11B, the angle of the locus of the transfer roller 11g1 obliquely outward to the sheet P becomes smaller. Thus, under the condition that the second angle θ2 is the same, the amount of the adhesive A that is peeled off from the adhesive tape T is suppressed as compared with the case of FIG. 11C. Therefore, stringing is less likely to occur, and the adhesive A is more easily cut.

  In addition, the drive unit 12 drives the adhesive cartridge 11 so that the second angle θ2 of the transfer unit 11g of the adhesive cartridge 11 shown in FIG. 9D takes a value within a predetermined range. The predetermined range of the second angle θ2 includes, for example, an angle range larger than the first angle θ1 such that the structures of the adhesive transfer mechanism 10 and the printer 1 do not unnecessarily increase the size of the sheet P. In addition to the transfer roller 11g1 being separated obliquely outward from the paper P and the second angle θ2 of the transfer portion 11g being increased, the effect of suppressing stringing becomes more prominent.

  As described above, when the transfer roller 11g1 is separated from the transfer area W1, the adhesive A remains on the adhesive tape T in an untransferred state up to the vicinity of the outer peripheral point of the transfer roller 11g1 closest to the paper P. Therefore, even if the adhesive cartridge 11 returns to the standby position and then starts to shift to the transfer state again, the adhesive tape T coated with the adhesive A contacts the transfer surface P2 of the paper P. Thereby, the idling of the adhesive cartridge 11 is suppressed.

  12A to 12D are schematic diagrams mainly showing the transfer load adjusting unit 13 among the components shown in FIGS. 9A to 9D, respectively. The transfer load adjusting unit 13 applies a load to the adhesive cartridge 11 on the paper P side such that the transfer load acting on the paper P from the transfer unit 11g in the transfer state of the adhesive cartridge 11 is substantially constant. Here, the transfer load is substantially constant when the transfer load of the pressure-sensitive adhesive cartridge 11 is completely constant without time variation, and the pressure-sensitive adhesive is uniformly transferred to the transfer surface P2 of the paper P. This includes a state where the transfer load fluctuates within a predetermined load range.

  As shown in FIGS. 12A to 12D, the transfer load adjustment unit 13 includes a transfer load adjustment cam 13a in addition to a transfer load adjustment cam 13a arranged in front of the cartridge drive cam 12g so as to overlap the cartridge drive cam 12g. It has a support arm 13b that contacts the outer periphery and the center. The left end of the support arm 13b is axially supported with respect to the rear frame B. The transfer load adjusting unit 13 has an urging member 13c connected to the right end of the support arm 13b. The biasing member 13c includes, for example, a spring. The transfer load adjusting unit 13 has a pressing arm 13d connected to the urging member 13c. The biasing member 13c is connected at an upper end to the support arm 13b, and at an opposite lower end to the pressing arm 13d.

  The pressing arm 13d is axially supported by the rear frame B at the left end opposite to the right end connected to the urging member 13c. The pressing arm 13d has an engaging hole 13d1 at a substantially central portion in the left-right direction. The engagement hole 13d1 is engaged with a pin 11a2 protruding from the frame 11a on which the adhesive cartridge 11 is mounted.

  The urging member 13c connected to the pressing arm 13d applies an urging force for urging the pressing arm 13d toward the sheet P to the pressing arm 13d. More specifically, the urging member 13c is connected to the pressing arm 13d in a state where the urging member 13c extends from a free state where no external force is applied. Since the upper end of the urging member 13c is supported by the support arm 13b, the lower end applies an urging force for urging the pressing arm 13d upward to the pressing arm 13d.

  At this time, since the left end of the pressing arm 13d is axially supported by the rear frame B, an upward urging force acts on the pin 11a2 from the engagement hole 13d1. Therefore, the adhesive cartridge 11 is urged upward through the frame 11a.

  When the transfer load adjusting cam 13a rotates clockwise in conjunction with the cartridge driving cam 12g, the position of the contact portion between the transfer load adjusting cam 13a and the support arm 13b changes. As a result, the angle of the support arm 13b is changed while the left end is axially supported with respect to the rear frame B. Therefore, when the distance between the support arm 13b and the pressing arm 13d changes and the spring length changes, the urging force of the urging member 13c changes.

  More specifically, as shown in FIG. 12A, when the adhesive cartridge 11 is at the standby position, the distance between the support arm 13b and the pressing arm 13d is small, and the spring length of the urging member 13c is smaller than the natural length. Is also slightly larger. Accordingly, the urging force from the pressing arm 13d toward the sheet P acting on the adhesive cartridge 11 is small.

  As shown in FIG. 12B, when the adhesive cartridge 11 starts to shift from the retracted state to the transfer state, the distance between the support arm 13b and the pressing arm 13d becomes larger than when the adhesive cartridge 11 is at the standby position. . Therefore, the urging force from the pressing arm 13d toward the sheet P acting on the adhesive cartridge 11 becomes larger.

  As shown in FIG. 12C, when the adhesive cartridge 11 is in the middle of the transfer state, the interval between the support arm 13b and the pressing arm 13d is even larger than when the adhesive cartridge 11 starts to shift to the transfer state. . Therefore, the urging force from the pressing arm 13d to the sheet P acting on the adhesive cartridge 11 is further increased.

  As shown in FIG. 12D, when the adhesive cartridge 11 starts to shift from the transfer state to the retracted state, the distance between the support arm 13b and the pressing arm 13d becomes maximum. Therefore, the urging force of the pressing arm 13d toward the sheet P acting on the adhesive cartridge 11 is maximized.

  In this way, as shown in FIGS. 10B to 10D, the transfer load F onto the sheet P by the adhesive cartridge 11 is changed to the first vertical load F1 based on the pins 12h projecting from the cartridge driving cam 12g, and the frame 11a. Is equal to the sum of the second load F2 based on the pressing arm 13d engaging with the pin 11a2. That is, the adhesive transfer mechanism 10 changes the second load F2 in response to the change in the first load F1 based on the movement of the adhesive cartridge 11, so that the paper is transferred from the transfer unit 11g in the transfer state of the adhesive cartridge 11. The transfer load F acting on P is maintained substantially constant.

Table 1 is a table showing a numerical example of the second load F2 when the transfer load F is kept constant.

  For example, consider a case where the transfer load F is kept constant at 1000 gf. At this time, when the transfer roller 11g1 is positioned at the mark S3, 770 gf is required as the second load F2. When the transfer roller 11g1 is at the position S34 between the mark S3 and the mark S4, 940 gf is required as the second load F2. When the transfer roller 11g1 is located at the mark S4, 1000 gf is required as the second load F2. When the transfer roller 11g1 is at the position S45 between the mark S4 and the mark S5, 1070 gf is required as the second load F2. When the transfer roller 11g1 is positioned at the mark S5, 1430 gf is required as the second load F2.

  FIG. 13 is a diagram illustrating values at respective positions of the transfer load F and the second load F2 when the adhesive cartridge 11 is in the transfer state, based on a numerical example of Table 1.

  As shown in FIG. 13, when the pressure-sensitive adhesive cartridge 11 is in the transfer state, the second load F2 monotonously increases from the beginning to the end of the transfer state in order to maintain the transfer load F at a constant value of, for example, 1000 gf. . When the transfer roller 11g1 is located between the mark S3 and the mark S4, the second load F2 is smaller than the transfer load F. When the transfer roller 11g1 is positioned at the mark S4, the second load F2 becomes equal to the transfer load F. When the transfer roller 11g1 is located between the mark S4 and the mark S5, the second load F2 becomes larger than the transfer load F.

  For example, as shown in FIG. 10B, when the transfer roller 11g1 is located between the mark S3 and the mark S4, the first load F1 acts on the adhesive cartridge 11 toward the paper P, and is positive with respect to the transfer load F. Works. Therefore, the second load F2 may be relatively small, and is equal to a value obtained by subtracting the absolute value of the first load F1 from the transfer load F.

  For example, as shown in FIG. 10C, when the transfer roller 11g1 is positioned at the mark S4, the driving force from the pin 12h to the adhesive cartridge 11 works in the left-right direction, and the first load F1 in the up-down direction becomes zero. Therefore, the second load F2 becomes equal to the transfer load F.

  For example, as shown in FIG. 10D, when the transfer roller 11g1 is located between the mark S4 and the mark S5, the first load F1 acts on the adhesive cartridge 11 toward the side opposite to the sheet P, Acts negatively. Therefore, the second load F2 needs to be relatively large, and is equal to a value obtained by adding the absolute value of the first load F1 to the transfer load F.

  FIGS. 14A to 14D are schematic diagrams mainly showing the pressing member 14, the pressing member adjusting unit 15, and the transfer platen 16 among the components shown in FIGS. 9A to 9D, respectively. As described above, the printer 1 does not have a mechanism for holding the sheet P while the sheet P is being conveyed downstream of the printing unit 23. Therefore, a mechanism is required that reliably presses the sheet P near the transfer area W1 when the sheet P stops and the adhesive is transferred to the transfer surface P2. Therefore, the pressure-sensitive adhesive transfer mechanism 10 has the components shown in FIGS. 14A to 14D.

  The holding member adjusting unit 15 drives the holding member 14 in conjunction with the driving unit 12. When the pressure-sensitive adhesive cartridge 11 is in the transfer state, the pressing member 14 presses the sheet P in conjunction with the pressure-sensitive adhesive cartridge 11. More specifically, the holding member 14 holds the sheet P by sandwiching the sheet P with the transfer platen 16. On the other hand, when the adhesive cartridge 11 is in the retracted state, the pressing member 14 separates from the paper P in conjunction with the adhesive cartridge 11. Thus, the holding member 14 also functions as a guide for supporting the sheet P from below when the sheet P is being conveyed.

  As shown in FIGS. 14A to 14D, a pair of pressing members 14 are arranged on both sides of the sheet P in a state of being separated from each other along a direction intersecting with the transport direction of the sheet P. The holding member 14 is disposed on the same side of the sheet P as the adhesive cartridge 11. The pressing member 14 is disposed on the opposite side of the transfer platen 16 with the sheet P interposed therebetween. For example, as shown in FIG. 14B, the pressing member 14 presses the same surface of the sheet P as the transfer surface P2 on which the adhesive is transferred. More specifically, the pair of pressing members 14 respectively press the same surface as the transfer surface P2 near the outside of both ends of the transfer area W1 in the direction intersecting with the transport direction of the sheet P. At this time, the transfer platen 16 supports the same surface as the printing surface P1 of the paper P.

  The pressing member adjusting unit 15 moves the pair of pressing members 14 toward the sheet P so as to press the sheet P when the adhesive cartridge 11 is in the transfer state. For example, when the adhesive cartridge 11 starts to shift from the retracted state to the transfer state, the pressing member adjusting unit 15 pushes up the pair of pressing members 14 together. The holding member adjusting section 15 moves the pair of holding members 14 to the side opposite to the sheet P so as to be separated from the sheet P when the adhesive cartridge 11 is in the retracted state. For example, when the adhesive cartridge 11 starts to shift from the transfer state to the retracted state, the pressing member adjusting unit 15 lowers the pair of pressing members 14 together.

  As shown in FIG. 14A, the pressing member adjusting section 15 has a first pressing arm 15b that comes into contact with the outer periphery of the pressing member driving cam 15a at the center in addition to the pressing member driving cam 15a also shown in FIG. 8B. The first pressing arm 15b has a first projection 15b1 protruding forward from above the contact portion with the pressing member driving cam 15a, and a second projection 15b2 protruding forward from the left side of the first projection 15b1. The pressing member adjusting section 15 has a second pressing arm 15c disposed in front of the first pressing arm 15b so as to overlap the right half of the first pressing arm 15b. The second holding arm 15c has an engagement hole 15c1 that engages with the first projection 15b1 of the first holding arm 15b, and a projection 15c2 that projects forward from the right side of the engagement hole 15c1. The first holding arm 15b and the second holding arm 15c operate in conjunction with each other based on the engagement between the first projection 15b1 and the engagement hole 15c1.

  The holding member adjusting section 15 has a biasing member 15d connected to the right end of the first holding arm 15b. The biasing member 15d includes, for example, a spring. The lower end of the urging member 15d is disposed further forward than the pressing member driving cam 15a, and is axially supported by a front frame (not shown) facing the rear frame B in the front-rear direction. When the first pressing arm 15b is in contact with the pressing member driving cam 15a and the second protrusion 15b2 is axially supported with respect to the front frame, the urging member 15d pushes the left end of the first pressing arm 15b to the sheet P. A biasing force biasing the side is applied to the first holding arm 15b.

  More specifically, the urging member 15d is connected to the first holding arm 15b in a state where the urging member 15d extends from a free state in which no external force is applied. Since the lower end of the urging member 15d is axially supported by the front frame, the upper end urges the right end of the first holding arm 15b downward. At this time, the left end of the first holding arm 15b is urged upward.

  When the adhesive cartridge 11 is at the standby position, the first pressing arm 15b is maintained substantially horizontal by the support by the pressing member drive cam 15a and the front frame. At this time, the second holding arm 15c is substantially horizontal like the first holding arm 15b by the engagement of the engagement hole 15c1 and the first projection 15b1 in a state where the projection 15c2 is supported by the front frame. Is maintained.

  When the pressing member driving cam 15a rotates clockwise in conjunction with the cartridge driving cam 12g, the contact state between the pressing member driving cam 15a and the first pressing arm 15b changes. Thereby, the angle of each of the first holding arm 15b and the second holding arm 15c changes.

  More specifically, as shown in FIG. 14B, FIG. 14C, and FIG. 14D, when the adhesive cartridge 11 is in each state, the pressing member driving cam 15a and the first pressing arm 15b are separated from each other, and Become. At this time, the right end of the first holding arm 15b moves downward by the urging force from the urging member 15d with the second protrusion 15b2 as a fulcrum, and the left end moves upward. That is, the first holding arm 15b is inclined obliquely downward from the left to the right. At this time, the left end of the second holding arm 15c moves downward by the engagement between the engagement hole 15c1 and the first projection 15b1, and the right end moves upward with the projection 15c2 as a fulcrum. That is, the second holding arm 15c is inclined obliquely downward from the right side to the left side.

  As described above, the pressing member adjusting section 15 pushes up the pair of pressing members 14 toward the sheet P so as to press the sheet P when the adhesive cartridge 11 is in the transfer state. More specifically, the first holding arm 15b pushes up the left holding member 14, and the second holding arm 15c pushes up the right holding member 14.

  The pressing member adjusting unit 15 moves the pressing member 14 toward the sheet P at the same time as the adhesive cartridge 11 shifts to the transfer state, and opposes the pressing member 14 with the sheet P at the same time as the adhesive cartridge 11 shifts to the retracted state. It may be moved to the side. The pressing member adjusting unit 15 moves the pressing member 14 toward the sheet P when the adhesive cartridge 11 is in the retracted state before the transfer state, and moves the adhesive cartridge 11 from the transfer state to the retracted state. The holding member 14 may be moved to the side opposite to the sheet P in the state where the transfer has been made. In this case, displacement of the sheet P caused by the transfer of the adhesive to the sheet P by the adhesive cartridge 11 can be suppressed more reliably, and the transfer accuracy of the adhesive is improved.

  FIG. 15A is a front view showing the positions of the pair of holding members 14 when the cover 1b is opened. FIG. 15B is a front view showing the positions of the pair of holding members 14 when the cover 1b is closed. FIG. 16A is a top view showing the positions of the pair of pressing members 14 when the cover 1b is opened. FIG. 16B is a top view showing the positions of the pair of pressing members 14 when the cover 1b is closed. FIGS. 15A, 16A, and 16B mainly show a part of the pressure-sensitive adhesive transfer mechanism 10 including the pair of pressing members 14. FIG. 15B mainly illustrates a part of the adhesive transfer mechanism 10 including the pressing member 14 and the transfer platen 16 and the cover 1b.

  As shown in FIGS. 15A to 16B, the interval between the pair of pressing members 14 in a state where the cover 1 b constituting a part of the housing 1 a in which the adhesive transfer mechanism 10 is housed is open is the same as that in the state where the cover 1 b is closed. Is larger than the interval between the pressing members 14. At this time, the interval between the pair of pressing members 14 is larger than the width of the adhesive cartridge 11 in the left-right direction. As shown in FIG. 15B, the interval between the pair of pressing members 14 in a state where the cover 1b is closed is smaller than the width of the sheet P.

  More specifically, the pressing member 14 is connected to the arm 14b with the protrusions 14a formed on the front and rear surfaces as fulcrums. As shown in FIGS. 4 and 15B, when the cover 1b is closed, a pushing piece 1d projecting downward in the cover 1b in a substantially L-shape pushes the arm 14b downward. The angle of the arm 14b with respect to the horizontal direction is relatively large when the cover 1b is open, but becomes relatively small when the cover 1b is closed and the pushing piece 1d pushes the arm 14b. Thereby, each of the pair of pressing members 14 slides inward in the left-right direction, and the interval therebetween decreases.

  In FIGS. 16A and 16B, the leading end E of the pressing member 14 on the side that comes into contact with the paper P is formed linearly along the front-rear direction, but the shape is not limited to this. For example, the tip E may have a sawtooth shape. At this time, for example, a groove corresponding to the saw-shaped tip E may be formed on the outer surface of the transfer platen 16 facing the sheet P, and the groove and the saw-shaped tip E may be engaged with the sheet P therebetween. May hold the paper P. Further, for example, only the front end E of the pressing member 14 or the entire pressing member 14 may be formed of a material having a large friction coefficient such as rubber. As described above, the frictional force between the sheet P and the pressing member 14 increases, and the adhesive is more accurately transferred in a state where the sheet P is more reliably held by the pressing member 14.

  In the printer 1 according to one embodiment, conveyance and cutting of the paper P, printing of the paper P, transfer of the adhesive, and the like are controlled by a printer control unit 30 including a microcomputer.

  FIG. 17 is a block diagram showing a circuit configuration of the printer 1 shown in FIG.

  The printer 1 shown in FIG. 1 has a printer control unit 30 shown in FIG. 17 therein. The printer 1 further includes a platen roller control circuit 40, a print head control circuit 50, a movable blade control circuit 60, and a drive unit control circuit 70. The printer control unit 30 is connected to each of a platen roller control circuit 40, a print head control circuit 50, a movable blade control circuit 60, and a drive unit control circuit 70. The printer control unit 30 has a CPU 31, a RAM 32, and a ROM 33. The ROM 33 includes a platen roller control program for controlling the platen roller control circuit 40, a print head control program for controlling the print head control circuit 50, a movable blade control program for controlling the movable blade control circuit 60, and a drive unit control circuit 70. Various programs such as a drive unit control program to be controlled are stored.

  The platen roller control circuit 40 is connected to a stepping motor (not shown) that rotates the platen roller 23a of the printing unit 23 shown in FIG. The print head control circuit 50 is connected to the print head 23b of the print unit 23 shown in FIG. The movable blade control circuit 60 is connected to the motor 24b of the cutting section 24 shown in FIG. The drive unit control circuit 70 is connected to the motor 12a of the drive unit 12 and the sensor 12j of the drive unit 12 that detects the rotational position of the sensor cam 12i and the like shown in FIG.

  The platen roller control circuit 40 drives the stepping motor and rotates the platen roller 23a according to the control of the CPU 31 based on the platen roller control program. When the platen roller 23a rotates counterclockwise in FIG. 3, the paper P is transported in the transport direction.

  The print head control circuit 50 causes the print head 23b to execute a print operation on the print surface P1 of the paper P under the control of the CPU 31 based on the print head control program. The print head 23b performs printing on the print surface P1 of the paper P in contact with the heating elements by selectively causing the plurality of heating elements to generate heat under the control of the CPU 31.

  The movable blade control circuit 60 drives the motor 24b and reciprocates the movable blade 24c in the vertical direction according to the control of the CPU 31 based on the movable blade control program. Thereby, the sheet P is cut.

  The drive unit control circuit 70 drives the motor 12a under the control of the CPU 31 based on the drive unit control program. The cam gear 12e shown in FIG. 4 rotates clockwise by the driving of the motor 12a, the cartridge driving cam 12g of the driving unit 12, the transfer load adjusting cam 13a of the transfer load adjusting unit 13, and the pressing member driving cam of the pressing member adjusting unit 15. 15a rotates clockwise in conjunction therewith. Thus, the above-described function based on each cam described with reference to FIGS. 9A to 14D is realized.

  When the cam gear 12e shown in FIG. 4 rotates clockwise by the drive of the motor 12a, the sensor cam 12i also rotates clockwise in conjunction with another cam. At this time, the drive unit control circuit 70 receives a detection signal from the sensor 12j of the drive unit 12, which detects the rotational position and the like of the sensor cam 12i. The driving unit control circuit 70 controls the driving of the adhesive cartridge 11 by the driving unit 12, the adjustment of the transfer load acting on the sheet P from the transfer unit 11g, and the driving of the pressing member 14 according to the control of the CPU 31 based on the received detection signal. Control every cycle. One cycle includes the time from when the adhesive cartridge 11 starts moving from the standby position to when it returns to the standby position again.

  As shown in FIGS. 8A and 8B, the drive plate 12g1, the cartridge drive cam 12g, the transfer load adjusting cam 13a, the sensor cam 12i, the cam gear 12e, and the pressing member drive cam 15a are coaxially arranged on the shaft 12f, so that the drive is performed. The unit control circuit 70 can control the driving of the adhesive cartridge 11, the adjustment of the transfer load, and the driving of the pressing member 14 with one sensor 12j. Therefore, the cost is reduced and the control system is simplified.

  Next, the operation of the main program executed by the printer control unit 30 shown in FIG. 17 will be described.

  The main program starts when the power of the printer 1 is turned on. First, when the CPU 31 of the printer control unit 30 determines that a print command has been generated, the CPU 31 drives the stepping motor to start rotation of the platen roller 23a and starts printing on the print surface P1 of the paper P by the print head 23b. . When the platen roller 23a rotates counterclockwise, the sheet P is transported in the transport direction with the curl corrected by the decurling unit 22.

  When determining that the area corresponding to the transfer area W1 on the transfer surface P2 of the sheet P has reached just above the adhesive cartridge 11, the CPU 31 stops driving the stepping motor and stops the rotation of the platen roller 23a. That is, the conveyance of the paper P is stopped. Thereafter, the CPU 31 drives the motor 12a to start the clockwise rotation of the cam gear 12e. When the cartridge driving cam 12g, the transfer load adjusting cam 13a, and the pressing member driving cam 15a rotate clockwise in conjunction with each other, the adhesive cartridge 11 is attached to the transfer surface P2 of the paper P printed by the printing unit 23. Transcribe

  The CPU 31 drives the stepping motor again to restart the rotation of the platen roller 23a, and starts the remaining printing (reprinting step) on the printing surface P1 of the paper P by the print head 23b. Thereafter, when the CPU 31 determines that the printing of the paper P on the printing surface P1 is completed, the conveyance of the paper P is stopped, the motor 24b is driven, and the movable blade 24c is reciprocated in the vertical direction, so that the paper P is removed. Disconnect. After the printing is completed, the sheet P may be conveyed to a position where the sheet P is cut (cutting position) as necessary. In this case, after transporting the paper P to the cutting position, the CPU 31 stops transporting the paper P and cuts the paper P. In other words, the cutting of the paper P is performed in a state where the printing is completed and the conveyance of the paper is stopped. When there is no remaining print, the CPU 31 only carries the paper P and does not print. That is, in this case, the CPU 31 drives the stepping motor to start the rotation of the platen roller 23a, and conveys the sheet P to the cutting position. Thereafter, the CPU 31 cuts the sheet P by stopping the conveyance of the sheet P and driving the motor 24b to reciprocate the movable blade 24c in the vertical direction.

  The transfer of the adhesive in the above operation may be performed two or more times. Further, the transfer area W1 for transferring the adhesive may be an arbitrary position in the transport direction of the sheet P. That is, the adhesive material may be transferred to an arbitrary position in the paper transport direction an arbitrary number of times.

  Note that the CPU 31 may drive the stepping motor and rotate the platen roller 23a clockwise to convey the paper P in a direction opposite to the conveyance direction (hereinafter, referred to as back feed). By doing so, the printer 1 can adjust the printing position, the transfer position of the adhesive, and the cutting position (size of the paper P) of the paper P. Any structure and mechanism can be adopted for performing the back feed in the printer 1. FIG. 18 shows each operation state (states SA to SO) in a specific example (pattern 1 to pattern 3) of the control method to which the back feed operation is added. The respective operations of Pattern 1 to Pattern 3 are respectively shown by the flowcharts of FIGS. As shown in FIG. 18, in the patterns 1 to 3, the states SA to SD are all common, and the states after the state SD are different from each other. Hereinafter, the operation of each control method will be described with reference to FIGS.

(Operation of pattern 1)
The pattern 1 is a basic operation for printing the paper P, transferring the adhesive, and cutting the paper P. As shown in FIG. 18, in the pattern 1, following the states SA to SD, transition is made to the states SE to SG. State SA is an initial state. In the initial state, the paper P projects a predetermined length (d1) in a forward direction from immediately above the printing unit 23. d1 is determined by the positional relationship between the printing unit 23 and the cutting unit 24, and is, for example, 11 mm.

  FIG. 19 is a flowchart illustrating a control method according to Pattern 1. First, the CPU 31 feeds back the paper P until the end of the paper P reaches a position immediately above the printing unit 23 (step S100). The state SB indicates a state after the paper P is back-fed. By back feeding the paper P in this manner, the print start position can be adjusted to the vicinity of the front end of the paper P (hereinafter, referred to as the front end), and an excessive margin is added to the front end of the paper P. Can be prevented from occurring.

  Here, in the state SB, a region of a predetermined length d2 (for example, a region 3 mm from the front end of the paper) of the front end of the paper P protrudes forward from immediately above the printing unit 23. That is, “a state in which the end of the sheet P has reached the vicinity immediately above the printing unit 23” indicates a state in which the front end of the sheet P projects forward from immediately above the printing unit 23. By providing a margin at the end of the paper P in this way, it is possible to prevent a printing error due to a printing position error and to reliably print on the paper P.

  Subsequently, the CPU 31 prints on the paper P while transporting the paper P (step S110). Specifically, the CPU 31 drives the stepping motor based on the print command to start the rotation of the platen roller 23a, and performs printing on the print surface P1 of the paper P by the print unit 23. The state SC indicates a state after printing is performed on the paper P.

  Subsequently, when the CPU 31 determines that the area corresponding to the transfer area W1 of the sheet P has reached just above the adhesive transfer mechanism 10, the CPU 31 stops the conveyance of the sheet P and transfers the adhesive by the adhesive transfer mechanism 10 ( Step S120). At the time of transfer, the sheet P is held near the transfer area W1 by the pressing member 14. The state SD indicates a state after the transfer of the adhesive by the adhesive transfer mechanism 10. As described above, the holding member 14 separates from the paper P while the paper P is being conveyed.

  Subsequently, the CPU 31 performs the remaining printing on the paper P while transporting the paper P (step S130). Specifically, the CPU 31 drives the stepping motor again to restart the rotation of the platen roller 23a, and performs the remaining printing on the printing surface P1 of the paper P by the print head 23b. The state SE indicates a state after the remaining printing on the paper P is performed.

  Subsequently, the CPU 31 cuts the paper P by the cutting unit 24 (step S140). Specifically, when the CPU 31 determines that the printing on the printing surface P1 of the paper P is completed, the CPU 31 stops the transport of the paper P, drives the motor 24b, and reciprocates the movable blade 24c in the up-down direction. Cut P. After the printing is completed, the paper P may be conveyed to the cutting position as needed. In this case, after transporting the paper P to the cutting position, the CPU 31 stops transporting the paper P and cuts the paper P. The state SF indicates a state after the sheet P has been cut. The state SG is a state after the paper P is obtained by the user. The state SG is the same state as the initial state SA.

(Operation of pattern 2)
FIG. 20 is a flowchart illustrating a control method according to Pattern 2. In general, the pattern 2 is different from the pattern 1 in that the adhesive is transferred not only to the front end of the sheet P but also to the rear end (hereinafter, referred to as a rear end). Steps S <b> 100 to S <b> 130 are the same operations as those of the pattern 1, and thus description thereof will be omitted.

  After the step S130, when the CPU 31 determines that the area corresponding to the transfer area W1 ′ of the paper P has reached just above the adhesive transfer mechanism 10, the CPU 31 stops the conveyance of the paper P, and the adhesive transfer mechanism 10 The agent is transferred (step S131). At the time of transfer, the sheet P is held near the transfer area W1 'by the pressing member 14. As described above, the holding member 14 is separated from the paper P while the paper P is being conveyed. The state SH indicates a state after step S130, and the state SI indicates a state after step S131. Note that the transfer area W1 ′ corresponds to “another transfer area” in the present invention.

  Subsequently, the CPU 31 feeds the paper P back until the rear end of the transfer area W1 'reaches just above the cutting section 24 (step S132). Subsequently, the CPU 31 cuts the paper P by the cutting unit 24 (step S140). Specifically, when the CPU 31 determines that printing on the printing surface P1 of the paper P is completed, the CPU 24 drives the motor 24b to reciprocate the movable blade 24c in the vertical direction, thereby cutting the paper P. State SJ indicates a state after step S140. Here, as shown in the state SI, the rear end of the transfer area W1 ′ is separated from the cutting position by a predetermined length (d3). Then, by back-feeding the paper P over the predetermined length, the rear end of the transfer area W1 'can be moved right above the cutting portion 24 as in the state SJ. Here, d3 is determined by the distance between the adhesive transfer mechanism 10 and the cutting section 24, and is, for example, 9.9 mm. The state SK is a state after the paper P is obtained by the user, and is the same state as the initial state SA.

  As described above, according to the operation of the pattern 2, the adhesive can be transferred to the front end and the rear end of the paper P, so that the adhesive strength is improved as compared with the case where the adhesive is transferred only to the front end of the paper P. Can be done. Particularly, when the distance from the front end to the rear end of the sheet P (hereinafter, referred to as the ticket length) is long, the sheet P is more firmly attached to the target object than the adhesive is transferred only to the front end. Can be.

  Note that the rear end of the sheet P, that is, the end on the transfer area W1 'side is cut after printing, and the error in the cutting position is smaller than the error in the print position. The margin can be made narrower than the end of. By narrowing the margin, it is possible to prevent the generation of an excessive margin at the rear end and save paper. Further, by utilizing the fact that the margin at the rear end of the paper P can be made smaller, the printing order by the printer 1 may be reversed. In other words, when printing is performed on a plurality of lines (N lines), the printer 1 performs printing in order from the Nth line and performs printing (hereinafter, referred to as inverted printing) such that the first line is located at the rear end. Is also good. By inverting the printed paper P by 180 degrees, the upper margin on the first line can be minimized. In the reverse printing, when the adhesive is transferred to the end on the first line side of the print, the cutting section 24 and the adhesive transfer mechanism 10 are provided from the upstream in the transport direction. It is also possible to transfer the agent at once. By performing these processes at the same time, the throughput can be improved.

  In the pattern 2, the example in which the adhesive is transferred to the two positions of the front end portion and the rear end portion of the sheet P has been described. However, the present invention is not limited to this. You may make it transfer an adhesive to more than a location.

(Operation of pattern 3)
FIG. 21 is a flowchart illustrating a control method according to Pattern 3. The pattern 3 differs from the patterns 1 and 2 in that the pattern 3 is cut while leaving a part of the sheet P (hereinafter, referred to as a partial cut), and the sheet P is conveyed after being cut by the partial cut. Steps S <b> 100 to S <b> 120 are the same operations as those of the pattern 1, and thus description thereof will be omitted.

  After step S120, the CPU 31 causes the cutting unit 24 to cut the paper P by partial cutting (step S150). Specifically, when the CPU 31 determines that the printing on the printing surface P1 of the paper P has been completed, the CPU 31 drives the motor 24b to reciprocate the movable blade 24c vertically over a predetermined distance, so that the paper P is partially moved. Cut by cutting. The predetermined distance is shorter than the case where the sheet P is completely cut. The state SL indicates a state after the sheet P is cut by the partial cut.

  Subsequently, the CPU 31 conveys the paper P for a predetermined length (d4) until the front end of the paper P projects forward from the paper discharge unit 1c (step S160). By protruding the front end of the sheet P forward from the sheet discharge unit 1c, the user can obtain the sheet P. State SM indicates a state after step S160. The predetermined length d4 is based on the distance between the sheet discharge unit 1c and the cutting unit 24. For example, when the distance between the sheet discharging unit 1c and the cutting unit 24 is 40 mm, in order for the front end of the sheet P to protrude a predetermined length (for example, 10 mm) forward from the sheet discharging unit 1c, the ticket length of the sheet P must be The sheet P is transported so that the length including d4 becomes 50 mm. For example, when the ticket length is 20 mm, the paper P is transported with d4 set to 30 mm. Here, since the paper P is cut by the partial cut in step S150, the paper P can be transported along the transport path even after the cutting.

  Subsequently, the CPU 31 detects whether or not the paper P has been acquired by the user (step S170). The detection process is repeated until the acquisition of the paper P is detected. When the acquisition of the paper P is detected, the process proceeds to step S180. The printer 1 includes a sensor for performing the detection process. As the sensor, an optical sensor or the like can be used as appropriate, and is provided in the vicinity of the paper discharge unit 1c.

  Subsequently, the CPU 31 feeds back the paper P over a predetermined length (d4) (step S180). State SN indicates a state immediately before the back feed operation, and state SO indicates a state immediately after the back feed operation. The state SO is the same state as the initial state SA. Note that the operations of step S170 and step S180 may be omitted. When the operation is omitted, it is not necessary to provide the sensor.

  As described above, according to the operation of the pattern 3, even when the ticket length of the sheet P is shorter than the distance between the sheet discharging unit 1c and the cutting unit 24, the user can easily obtain the sheet P. . Thus, according to the operation of the pattern 3, the degree of freedom of the ticket length can be increased. For example, when the back feed operation related to the pattern 3 is not performed, the minimum value of the ticket length is set to a distance between the sheet discharging unit 1c and the cutting unit 24 by a predetermined length of a protrusion that can be gripped by the user from the sheet discharging unit 1c. The added length. On the other hand, by performing the operation of the pattern 3, it is possible to discharge the sheet P having an arbitrary ticket length shorter than the length obtained by adding the protrusion to the distance between the sheet discharge section 1c and the cutting section 24.

  Further, in the case where the back feed is performed after the acquisition of the sheet P is detected in the operation of the pattern 3, it is possible to reduce the possibility that the sheet P cut by the partial cut causes an error such as a paper jam due to the back feed.

  The control methods of the above-described patterns 1 to 3 may be appropriately combined. FIG. 22 shows an operation in which pattern 1 and pattern 3 are combined. In the operation shown by the flowchart in FIG. 22, after steps S100 to S130 similar to those in pattern 1, the CPU 31 cuts the sheet P by partial cutting (step S150). After that, steps S160 to S180 similar to the pattern 3 are executed. By doing so, even if the ticket length of the paper P to be discharged by the operation of the pattern 1 is short, the paper P is cut by the partial cut and transported until it protrudes from the paper discharge unit 1c. The paper P can be obtained by the user. Therefore, it is possible to discharge the sheet P having an arbitrary ticket length shorter than the length obtained by adding the protrusion to the distance between the sheet discharge unit 1c and the cutting unit 24.

  FIG. 23 is a flowchart showing an operation in which pattern 2 and pattern 3 are combined. In the operation shown by the flowchart in FIG. 23, after steps S100 to S132 of pattern 2, the CPU 31 causes the cutting unit 24 to cut the paper P by partial cutting (step S150). After that, steps S160 to S180 are executed as in pattern 3. In this way, even if the ticket length of the paper P discharged by the operation of the pattern 2 is short, the paper P is cut by the partial cut and transported until it protrudes from the paper discharge unit 1c. The paper P can be obtained by the user. Therefore, it is possible to discharge the sheet P having an arbitrary ticket length shorter than the length obtained by adding the protrusion to the distance between the sheet discharge unit 1c and the cutting unit 24.

  According to the printer 1 according to the above-described embodiment, by operating the printing unit 23, the adhesive transfer mechanism 10, and the cutting unit 24 in association with each other, it is possible to improve the technology related to printer control. it can. In particular, according to the printer 1 according to the present embodiment, the printing position on the paper P, the transfer position of the adhesive, and the cutting position of the paper P can be adjusted by using the back feed.

  Further, according to the pressure-sensitive adhesive transfer mechanism 10 according to the above-described embodiment, the structure of the sheet P is not unnecessarily increased. More specifically, the drive unit 12 drives the adhesive cartridge 11 so that the second angle θ2 of the transfer unit 11g is larger than the first angle θ1, so that the adhesive cartridge 11 intersects the transport direction. The moving area of the entire adhesive cartridge 11 when moving is reduced. More specifically, when the adhesive cartridge 11 is inclined at an angle corresponding to the second angle θ2, most of the adhesive cartridge 11 is located inside the transfer roller 11g1 in the direction intersecting the transport direction. Thereby, the width of the pressure-sensitive adhesive transfer mechanism 10 in the direction is reduced, and the apparatus is downsized. For example, even when the adhesive is transferred to a narrow paper P having a width equal to or less than the width of the adhesive cartridge 11, such as a receipt and a sticky note, the adhesive cartridge is provided on both sides of the paper P. It is not necessary to additionally form a space in which the entirety 11 can be arranged, and unnecessary enlargement of the apparatus for the paper P is avoided.

  By driving the adhesive cartridge 11 so that the transfer portion 11g is separated obliquely outward from the transfer area W1 when the adhesive cartridge 11 shifts from the transfer state to the retracted state, stringing hardly occurs, and Discharge of the agent is improved. At this time, since the adhesive cartridge 11 is tilted at an angle corresponding to the second angle θ2, even if the adhesive cartridge 11 is driven so that the transfer portion 11g is separated obliquely outward, the device for the sheet P cannot be moved. The necessary enlargement is avoided. In addition, even if the pressure-sensitive adhesive cartridge 11 returns to the standby position and then starts to shift to the transfer state again, idling of the pressure-sensitive adhesive cartridge 11 is suppressed. At this time, since the adhesive cartridge 11 is inclined at an angle corresponding to the first angle θ1, the adhesive roller 11 is closest to the paper P of the transfer roller 11g1 of the transfer unit 11g inclined at the second angle θ2 as shown in FIG. 11B. The adhesive tape T comes into contact with the outer peripheral point on the right side of the outer peripheral point as a starting point. At such an outer peripheral point, since the adhesive A is in an untransferred state, the adhesive is reliably transferred to the transfer surface P2 of the paper P.

  The transfer load adjusting unit 13 applies a second load F2 to the sheet P of the adhesive cartridge 11 so that the transfer load F acting on the sheet P from the transfer unit 11g in the transfer state is substantially constant. Is suppressed. For example, if the transfer load F varies and becomes smaller than other portions, the adhesive may not be transferred at the portion where the transfer load F becomes smaller. On the other hand, for example, when the transfer load F increases, the loads applied to the gears, the cams, and the respective components such as the transfer unit 11g constituting the pressure-sensitive adhesive transfer mechanism 10 increase, and the product life may be shortened. In the pressure-sensitive adhesive transfer mechanism 10 according to one embodiment, these problems are solved by keeping the transfer load F constant at a desired value.

  According to the pressure-sensitive adhesive transfer mechanism 10 according to the embodiment as described above, the sheet P is securely held when the pressure-sensitive adhesive is transferred to the sheet P even when the apparatus is downsized. More specifically, the stopped sheet P is securely held by moving the pressing member 14 toward the sheet P so as to press the sheet P when the adhesive cartridge 11 is in the transfer state. Therefore, the adhesive is accurately transferred to the transfer surface P2 of the sheet P. When the pressure-sensitive adhesive cartridge 11 is in the retracted state, the pressing member 14 is moved to the side opposite to the sheet P so as to be separated from the sheet P, thereby supporting the sheet P from below when the sheet P is being conveyed. The pressing member 14 functions as a guide, and the paper P is stably conveyed.

  When the pressing member 14 presses the same surface of the sheet P as the transfer surface P2 on which the adhesive is transferred, the adhesive is transferred while the transfer surface P2 is pressed against the transfer platen 16 from below. Therefore, the adhesive is more accurately transferred in a state where the sheet P is more securely held by the pressing member 14.

  The pressing member driving cam 15a is arranged coaxially with the cartridge driving cam 12g, and is rotated in conjunction with the cartridge driving cam 12g by the driving of the driving unit 12, so that the motor 12a of the driving unit 12 is used as the same driving source and each cam is driven. Can be driven. Therefore, the number of drive sources is reduced, and the cost is reduced. Further, the drive system is simplified. These effects apply to the entire drive plate 12g1, the cartridge drive cam 12g, the transfer load adjustment cam 13a, the sensor cam 12i, the cam gear 12e, and the pressing member drive cam 15a, which are coaxially arranged on the shaft 12f.

  By arranging the pair of pressing members 14 on both sides of the sheet P, the sheet P is more reliably held from both sides in a direction intersecting with the transport direction. Therefore, the adhesive is more accurately transferred.

  Since the distance between the pair of pressing members 14 with the cover 1b opened is larger than the distance between the pair of pressing members 14 with the cover 1b closed, the adhesive cartridge 11 is moved to the frame 11a of the adhesive transfer mechanism 10. Workability when inserting from above is improved. More specifically, the adhesive cartridge 11 can be inserted in a state where interference between the adhesive cartridge 11 and the pair of pressing members 14 is suppressed. In addition, since the interval between the pair of pressing members 14 with the cover 1b closed is smaller than the width of the sheet P, the pair of pressing members 14 support the sheet P from below when the sheet P is being conveyed. And it functions reliably as a guide. Thereby, the paper P is stably conveyed.

  Since the front end E of the pressing member 14 on the side in contact with the sheet P has a saw-tooth shape, the coefficient of friction between the pressing member 14 and the sheet P increases. Therefore, the sheet P is more reliably held, and the adhesive is more accurately transferred.

  It will be apparent to one skilled in the art that the present invention may be embodied in other predetermined forms than those described above without departing from its spirit or essential characteristics. Accordingly, the foregoing description is by way of example and not limitation. The scope of the invention is defined not by the preceding description, but by the appended claims. Some of the changes that come within their equivalents are intended to be embraced therein.

  For example, the shape, arrangement, orientation, angle, number, and the like of each component described above are not limited to the above description and the contents shown in the drawings. The shape, arrangement, orientation, angle, number, and the like of each component may be arbitrarily configured as long as the function can be realized.

  In FIG. 13, the second load F2 has been described as monotonically increasing from the beginning to the end of the transfer state in order to maintain the value of the transfer load F constant. However, the dependency of the second load F2 on the transfer position is as follows. It is not limited to this. The second load F2 may have an arbitrary dependency corresponding to a change in the transfer position of the first load F1.

  Although the pair of pressing members 14 have been described as pressing the same surface as the transfer surface P2 of the sheet P, the present invention is not limited to this. The pair of pressing members 14 may press the same surface as the printing surface P1 of the paper P. Further, each of the pair of pressing members 14 does not have to press the sheet P from the same direction. For example, one of the pair of pressing members 14 may press the same surface as the printing surface P1 of the paper P, and the other may press the same surface as the transfer surface P2 of the paper P.

  Although it has been described that the pair of pressing members 14 are arranged on both sides of the sheet P in a state of being separated from each other, the present invention is not limited to this. For example, the pair of holding members 14 may be connected to each other.

  For example, the pressure-sensitive adhesive cartridge has an opening that is larger than the width of the transfer area W1 in the direction intersecting the transport direction and the width in the transport direction, and surrounds the transfer area W1 in the transfer state. 11 may be formed at the tip. At this time, there is no need to separately form the pressing member 14 on the adhesive transfer mechanism 10, and the space in which the adhesive cartridge 11 can be inserted into the frame 11a from above is larger. Therefore, it is possible to increase the volume of the pressure-sensitive adhesive by increasing the volume of the pressure-sensitive adhesive cartridge 11.

  It has been described that when the cover 1b is closed, each of the pair of pressing members 14 slides inward in the left-right direction, but is not limited thereto. The pair of pressing members 14 may have an arbitrary configuration such that an interval when the cover 1b is open is larger than an interval when the cover 1b is closed. For example, when the cover 1b is closed, each of the pair of pressing members 14 may move inward while being pushed up obliquely. For example, when the cover 1b is opened, each of the pair of pressing members 14 falls outward at a substantially right angle, and when the cover 1b is closed, each of the pair of pressing members 14 returns to the state shown in FIG. 15B again. Good.

  The adhesive cartridge 11 may further include, in addition to the above-described alignment mechanism, an optional mechanism that allows the adhesive tape T wound around the transfer roller 11g1 to pass through the center of the transfer roller 11g1. The pressure-sensitive adhesive cartridge 11 may further include an optional protection mechanism such as a shutter in order to suppress idling caused by the pressure-sensitive adhesive coming into contact with the worker's hand and the pressure-sensitive adhesive being peeled off from the pressure-sensitive adhesive tape T. . For example, the adhesive cartridge 11 may have a protection mechanism such that the transfer roller 11g1 is exposed to the outside only in the transfer state. Instead of such a protection mechanism, the adhesive transfer mechanism 10 may retreat the adhesive cartridge 11 to a position where the worker cannot reach.

  The adhesive cartridge 11 may have an arbitrary sensor that detects the rotation state of the transfer roller 11g1. The printer control unit 30 may acquire information about the rotation state from such a sensor. The information on the rotation state includes, for example, information on whether or not the transfer roller 11g1 is rotating, the number of rotations, and the like. The printer control unit 30 may determine whether or not the transfer roller 11g1 is idling based on the acquired information on the rotation state. For example, the printer control unit 30 may compare the rotation speed of the transfer roller 11g1 with respect to the moving distance of the transfer roller 11g1 in the transfer area W1 and a threshold. When determining that the rotation speed is smaller than the threshold value, the printer control unit 30 determines that the transfer roller 11g1 is idle. At this time, the printer control unit 30 executes any control such as increasing the transfer load F, stopping the drive unit 12, and notifying the operator of the detection of the idle rotation of the transfer roller 11g1 by any method. May be. As described above, continuous discharge of the sheet P to which the adhesive has not been transferred is avoided.

  The printer 1 may further include an arbitrary sensor capable of detecting environmental information. The environment information includes, for example, arbitrary information such as temperature, humidity, and atmospheric pressure. When the environmental information is a temperature, the printer 1 may further include an optional temperature sensor such as a thermistor. Generally, the lower the environmental temperature is, the harder the adhesive is transferred to the paper P. Therefore, the printer control unit 30 may drive the driving unit 12 based on the information on the environmental temperature acquired from the temperature sensor so as to slow down the moving speed of the adhesive cartridge 11 if the environmental temperature is low. Conversely, if the environmental temperature is high, the printer control unit 30 may drive the drive unit 12 to increase the moving speed of the adhesive cartridge 11 in order to shorten the transfer time and improve the transfer efficiency.

  The printer 1 may determine the type of the adhesive of the adhesive cartridge 11 based on the IC attached to the adhesive cartridge 11. The type of the adhesive includes, for example, any type such as a type based on a material and a type based on any property such as the strength or weakness of the adhesiveness. The printer control unit 30 may control the moving speed of the adhesive cartridge 11 based on the type of the adhesive. For example, in the case of the pressure-sensitive adhesive cartridge 11 having a strong pressure-sensitive adhesive, the pressure-sensitive adhesive is reliably transferred to the paper P even when the environmental temperature is low. The drive unit 12 may be driven so as to keep the moving speed of the cartridge 11 constant.

  As described above, under the control of the printer control unit 30 based on the environmental information and the type of the adhesive, the adhesive cartridge 11 can be moved at an optimum moving speed while realizing the reliable transfer of the adhesive according to the environmental information and the type of the adhesive. Can be moved.

  The pressure-sensitive adhesive transfer mechanism 10 according to one embodiment has been described as being mounted on the printer 1, but is not limited thereto. The pressure-sensitive adhesive transfer mechanism 10 can be mounted on various devices having an arbitrary paper transport mechanism for transporting the paper P.
