[0002] Conventionally, there has been known a laminating device that records an image on a first member pulled out from a first roll and bonds the first member on which the image has been recorded to a second member pulled out from a second roll (for example, Patent Document 1).

[0003] In the device described in Patent Document 1, the printing section forms a print image on the recording medium pulled out from the recording medium roll. The recording medium on which the print image has been formed is cut to a predetermined length in the first cutting section, transported to the laminating section, and superimposed on the laminating member pulled out from the laminating member roll by a guide roll in the laminating section. The superimposed recording medium and laminating member are heated by a pressurizing and heating roll, and separated in the second cutting section. The recording medium roll, the recording medium, the laminating member roll, and the laminating member correspond to the first roll, the first member, the second roll, and the second member, respectively.

[0029] The laminating device 1 according to the embodiment of the present invention will be described below. The embodiment described below is merely one example of the present invention, and it goes without saying that the embodiment of the present invention can be appropriately modified without changing the gist of the present invention. In the following description, the direction is expressed as the progress from the starting point of the arrow to the end point, and the direction is expressed as the movement on the line connecting the starting point and the end point of the arrow. In addition, the up-down direction 7 is defined based on the state in which the laminating device 1 is installed so that it can be used (the state of FIG. 1(A)), the front-rear direction 8 is defined with the surface on which the operation unit 12 and the display unit 13 are provided as the front, and the left-right direction 9 is defined when the laminating device 1 is viewed from the front. The up-down direction 7, the front-rear direction 8, and the left-right direction 9 are mutually perpendicular.

[0030] [Overview of Lamination Device 1] 1(A), the laminating device 1 according to this embodiment has a rectangular parallelepiped housing 11. An operation unit 12 and a display unit 13 are located on the front of the housing 11. An outlet 14 is located on the front of the housing 11 below the operation unit 12 and the display unit 13. The laminating device 1 creates a laminated finished product 100 by bonding two types of members together.

[0031] A tape-like first member 101 and a second member 102 are supplied to the laminating apparatus 1. As shown in Fig. 2, the first member 101 is wound around a cylindrical core material 113 to form a first roll 111. The second member 102 is wound around a cylindrical core material 114 to form a second roll 112. The first roll 111 and the second roll 112 are attached to a first holder 21 and a second holder 22 of the laminating apparatus 1, respectively.

[0032] The first member 101 is, for example, a transparent film. As shown in Fig. 1(B), the second member 102 is a member having an adhesive layer on at least one surface. The second member 102 is, for example, a backing paper having a first adhesive layer 103 on one surface of a tape layer 104 (the surface on the first member 101 side in the finished laminate 100) and a second adhesive layer 105 on the other surface of the tape layer 104. A release sheet 106 is provided on the opposite side of the tape layer 104 with the second adhesive layer 105 sandwiched therebetween.

[0033] The first member 101 and the second member 102 may be made of any material. The second member 102 may be, for example, a resin member such as PET or PVC (polyvinyl chloride), synthetic paper such as Yupo paper (registered trademark), or a metal member. The second member 102 may be transparent or opaque. The first member 101 and the second member 102 may have an adhesive layer on one surface, may have an adhesive layer on the other surface, may have an adhesive layer on both surfaces, or may not have an adhesive layer on both surfaces. When a material without an adhesive layer is used, the first member 101 and the second member 102 may be bonded together after an adhesive is applied, or may be bonded together by heat welding, pressure bonding, or the like.

[0034] 2, the recording surface 107 is the surface of the first member 101 on which an image is recorded. The back surface 108 is the surface of the first member 101 opposite the recording surface 107. The bonding surface 109 is the surface of the second member 102 that has the first adhesive layer 103.

[0035] The laminating device 1 bonds the first member 101 and the second member 102 by bringing the recording surface 107 of the first member 101 into close contact with the bonding surface 109 of the second member 102. The laminating device 1 cuts the bonded members into a predetermined size. This creates a finished laminated product 100 as shown in FIG. 1(B). The created finished laminated product 100 is discharged from the discharge port 14.

[0036] As shown in FIG. 2, the laminating device 1 includes a first holder 21, a second holder 22, an image recording unit 30, first to fourth conveying rollers 41 to 44, a laminating roller 50, member sensors 61 to 63, a first cutting unit 68, and a second cutting unit 69 inside a housing 11. In addition, the laminating device 1 includes a control unit 90 and various motors inside the housing 11 (see FIG. 3). A guide member (not shown) that supports the first member 101 is provided at a necessary position inside the housing 11. This forms a conveying path 15 that runs from the first holder 21 to the second cutting unit 69 via the image recording unit 30, the first cutting unit 68, and the laminating roller 50.

[0037] [First holder 21 and second holder 22] The first holder 21 and the second holder 22 are members that can rotate around an axis extending in the left-right direction 9. The thickness of the first holder 21 is equivalent to the inner diameter of the core material 113 of the first roll 111. The thickness of the second holder 22 is equivalent to the inner diameter of the core material 114 of the second roll 112. The first holder 21 and the second holder 22 are fixed to the housing 11 or a member fixed to the housing 11.

[0038] The first holder 21 and the second holder 22 are located at positions spaced apart from each other within the housing 11. In the configuration shown in Fig. 2, the first holder 21 is located near the center of the housing 11 in the up-down direction 7 and at the rear of the housing 11 in the front-rear direction 8. The second holder 22 is located at the upper part of the housing 11 in the up-down direction 7 and in front of the center of the housing 11 in the front-rear direction 8. The positions of the first holder 21 and the second holder 22 within the housing 11 are arbitrary.

[0039] Before the laminating apparatus 1 operates, a first roll 111 is attached to the first holder 21, and a second roll 112 is attached to the second holder 22. The first holder 21 rotatably supports the first roll 111. The second holder 22 rotatably supports the second roll 112. A first member 101 is drawn out from the first roll 111 supported by the first holder 21. A second member 102 is drawn out from the second roll 112 supported by the second holder 22. The first holder 21 is an example of a first support portion. The second holder 22 is an example of a second support portion.

[0040] [Image Recording Unit 30] The image recording unit 30 is located downstream of the first roll 111 on the transport path 15. The image recording unit 30 is located above the transport path 15 in the up-down direction 7 and between the first roll 111 and the first cutting unit 68 in the front-rear direction 8. The image recording unit 30 includes a carriage 31 and a recording head 32. Inside the housing 11, there are located two guide rails (not shown) that extend in the left-right direction 9 and have both ends fixed to the housing 11 or to a member fixed to the housing 11. The carriage 31 is placed on the two guide rails. The carriage 31 receives a driving force from a CR motor 83 (see FIG. 3) and moves in the left-right direction 9.

[0041] The recording head 32 is mounted on a carriage 31. A plurality of nozzles 33 are formed on the bottom surface of the recording head 32. As the carriage 31 moves, the recording head 32 moves in the left-right direction 9. A platen 34 is located below the movement range of the carriage 31. The recording head 32 ejects ink downward from the nozzles 33 while moving in the left-right direction 9. As a result, an image is recorded on the recording surface 107 of the first member 101 transported on the platen 34. In this way, the image recording unit 30 records an image on the first member 101 pulled out from the first roll 111.

[0042] [First to fourth conveyor rollers 41 to 44] The first to fourth conveying rollers 41 to 44 are positioned between the first roll 111 and the laminating roller 50. Specifically, the first conveying roller 41 and the second conveying roller 42 are positioned between the first roll 111 and the image recording unit 30 in the front-rear direction 8. The third conveying roller 43 and the fourth conveying roller 44 are positioned between the image recording unit 30 and the laminating roller 50 in the front-rear direction 8. The second conveying roller 42 is positioned in front of the first conveying roller 41 in the front-rear direction 8. The fourth conveying roller 44 is positioned in front of the third conveying roller 43 in the front-rear direction 8.

[0043] The first conveying roller 41 includes a first roller 411 and a second roller 412. The first roller 411 is located directly above the second roller 412. The first member 101 passes between the first roller 411 and the second roller 412. At this time, the first roller 411 abuts against the recording surface 107 of the first member 101, and the second roller 412 abuts against the back surface 108 of the first member 101. As a result, the first conveying roller 41 grips the first member 101. The first conveying roller 41 grips the first member 101 between the first roll 111 and the laminating roller 50.

[0044] The second roller 412 receives a driving force from the conveying motor 82 (see FIG. 3) and rotates about an axis extending in the left-right direction 9. Accordingly, the first roller 411 also rotates about an axis extending in the left-right direction 9. At this time, a force in a direction pulling the first member 101 from the first roll 111 acts on the first member 101. In addition, the second roller 412 receives a driving force in the opposite direction from the conveying motor 82 and rotates in the opposite direction, and accordingly the first roller 411 also rotates in the opposite direction. At this time, a force in a direction moving the first member 101 closer to the first roll 111 acts on the first member 101.

[0045] The second conveyor roller 42 includes a third roller 421 and a fourth roller 422. The third conveyor roller 43 includes a fifth roller 431 and a sixth roller 432. The fourth conveyor roller 44 includes a seventh roller 441 and an eighth roller 442. The second to fourth conveyor rollers 42 to 44 have the same configurations and functions as the first conveyor roller 41, and therefore will not be described here. The second to fourth conveyor rollers 42 to 44 grip the first member 101 between the first roll 111 and the laminating roller 50, similar to the first conveyor roller 41.

[0046] In this embodiment, of the two rollers included in the first to fourth conveyor rollers 41 to 44, the lower roller receives driving force from the conveyor motor 82. Alternatively, the upper roller may receive driving force from the conveyor motor 82, or both the upper and lower rollers may receive driving force from the conveyor motor 82.

[0047] [Laminating roller 50] The laminating roller 50 is located downstream of the image recording unit 30 on the conveying path 15. The laminating roller 50 is located between a first cutting unit 68 and a second cutting unit 69 in the front-rear direction 8. The laminating roller 50 includes a first laminating roller 51 and a second laminating roller 52. The first laminating roller 51 is located directly above the second laminating roller 52. The first laminating roller 51 and the second laminating roller 52 grip the first member 101 and the second member 102 with a predetermined force. As a result, the first member 101 and the second member 102 are laminated together to form a finished laminate product 100.

[0048] The second member 102 pulled out from the second roll 112 enters between the first laminating roller 51 and the second laminating roller 52. At this time, the laminating surface 109 of the second member 102 faces downward. The first member 101 that has passed through the image recording unit 30 and the first cutting unit 68 enters under the second member 102 between the first laminating roller 51 and the second laminating roller 52. At this time, the recording surface 107 of the first member 101 faces upward.

[0049] The second laminating roller 52 receives a driving force from a common motor 70 (see FIG. 3 ) and rotates about an axis extending in the left-right direction 9. Accordingly, the first laminating roller 51 also rotates about an axis extending in the left-right direction 9. The first laminating roller 51 and the second laminating roller 52 bond the first member 101 and the second member 102 together by bringing the recording surface 107 of the first member 101 and the bonding surface 109 of the second member 102 into close contact with each other. Note that the first laminating roller 51 may receive a driving force from the common motor 70, or both the first laminating roller 51 and the second laminating roller 52 may receive a driving force from the common motor 70. Also, the laminating roller 50 does not necessarily need to bond the first member 101 and the second member 102 together. For example, if the laminating device 1 has a portion downstream of the laminating roller 50 where thermal welding or pressure bonding is performed, a roller pair disposed in front of the portion and overlapping the first member 101 and the second member 102 serves as the laminating roller 50. The laminating roller 50 also overlaps the first member 101 and the second member 102.

[0050] [First cutting section 68] The first cutting unit 68 is located downstream of the conveying path 15 from the image recording unit 30. The first cutting unit 68 is located above the conveying path 15 in the up-down direction 7 and between the third conveying roller 43 and the fourth conveying roller 44 in the front-rear direction 8. The first cutting unit 68 cuts the first member 101 between the second conveying roller 42 and the laminating roller 50.

[0051] The first cutting unit 68 has any configuration capable of cutting the first member 101. The first cutting unit 68 may include, for example, a cutter carriage that receives a driving force from a cutting motor 84 (see FIG. 3) and moves in the left-right direction 9, and a cutter mounted on the cutter carriage. Alternatively, the first cutting unit 68 may include a moving blade that receives a driving force from the cutting motor 84 and moves in the up-down direction 7, and a fixed blade that faces the moving blade.

[0052] [Second cutting section 69] The second cutting unit 69 is located downstream of the laminating roller 50 in the conveying path 15. The second cutting unit 69 is located above the conveying path 15 in the up-down direction 7 and in front of the laminating roller 50 in the front-rear direction 8. The second cutting unit 69 simultaneously cuts the first member 101 and the second member 102 that have been bonded together by the laminating roller 50 downstream of the laminating roller 50 in the conveying direction.

[0053] The second cutting unit 69 has any configuration capable of cutting the first member 101 and the second member 102. The second cutting unit 69 may, for example, like the first cutting unit 68, include a cutter carriage that moves in the left-right direction 9 and a cutter, or may include a moving blade that moves in the up-down direction 7 and a fixed blade that faces the moving blade.

[0054] [Component Sensors 61-63] All of the component sensors 61 to 63 are located above the conveying path 15 in the up-down direction 7. The component sensor 61 is located between the first conveying roller 41 and the second conveying roller 42 in the front-rear direction 8. The component sensor 62 is located between the fourth conveying roller 44 and the laminating roller 50 in the front-rear direction 8. The component sensor 63 is located in front of the second cutting unit 69 in the front-rear direction 8. The component sensor 63 may be located downstream of the laminating roller 50 on the conveying path 15.

[0055] The member sensor 61 includes a light emitting element (not shown) that emits light toward the recording surface 107 of the first member 101 transported along the transport path 15, and a light receiving element (not shown) that receives the light reflected by the recording surface 107 of the first member 101. When the first member 101 is present below the member sensor 61, the light receiving element of the member sensor 61 receives the light reflected by the recording surface 107 of the first member 101, and the amount of light detected by the light receiving element is greater than the threshold value. On the other hand, when the first member 101 is not present below the member sensor 61, the light receiving element of the member sensor 61 does not receive the light reflected by the recording surface 107 of the first member 101, and the amount of light detected by the light receiving element is less than the threshold value. The member sensor 62 has the same configuration as the member sensor 61.

[0056] The member sensor 63 includes a light emitting element (not shown) that emits light toward a surface (hereinafter referred to as the opposite surface) of the second member 102 held by the laminating roller 50 opposite to the laminating surface 109, and a light receiving element (not shown) that receives light reflected by the opposite surface of the second member 102. When the second member 102 is present below the member sensor 63, the light receiving element of the member sensor 63 receives light reflected by the opposite surface of the second member 102, and the amount of light detected by the light receiving element becomes greater than the threshold value. On the other hand, when the second member 102 is not present below the member sensor 63, the light receiving element of the member sensor 62 does not receive light reflected by the opposite surface of the second member 102, and the amount of light detected by the light receiving element becomes less than the threshold value.

[0057] In this embodiment, the member sensors 61 to 63 including a light emitting element and a light receiving element are provided above the transport path 15. However, such member sensors 61 to 63 may be provided below the transport path 15.

[0058] [Control unit 90 and its peripheral parts] As shown in FIG. 3, the control unit 90 includes a CPU 91, a ROM 92, a RAM 93, and an EEPROM 94. The ROM 92 stores programs for controlling various operations of the laminating device 1. The EEPROM 94 stores various data used when the above programs are executed. The RAM 93 is used as a storage area for temporarily recording various data used when the CPU 91 executes the above programs, and as an area for expanding data and programs. When the laminating device 1 is powered on, the programs stored in the ROM 92 are copied and transferred to the RAM 93. The CPU 91 executes the programs stored in the RAM 93. This allows the control unit 90 to perform various controls.

[0059] The ASIC 95 is connected to an operation unit 12 and a display unit 13. The operation unit 12 detects pressing of an operation key and outputs a signal corresponding to the pressed operation key. The control unit 90 identifies the pressed operation key based on the output signal of the operation unit 12. The display unit 13 displays information related to the operation of the laminating device 1 on the screen based on an instruction from the control unit 90.

[0060] The recording head 32 is connected to the ASIC 95. The control unit 90 outputs a signal corresponding to image data to the recording head 32 via the ASIC 95. The recording head 32 ejects ink from a plurality of nozzles 33 provided in the recording head 32 in response to the signal output from the control unit 90.

[0061] The member sensors 61-63 are connected to the ASIC 95. The member sensors 61-63 output signals according to the amount of light detected by the light receiving elements. The control unit 90 determines whether or not the first member 101 or the second member 102 is present at the arrangement positions of the member sensors 61-63 based on the output signals of the light receiving elements.

[0062] [Various motors] The common motor 70, the first roll motor 81, the conveying motor 82, the CR motor 83, and the cutting motor 84 are connected to the ASIC 95. A drive circuit for controlling these motors is built into the ASIC 95. The control unit 90 outputs a drive signal for rotating each motor to the drive circuit corresponding to each motor. The drive circuit outputs a drive current corresponding to the drive signal output from the control unit 90 to the corresponding motor. This causes the corresponding motor to rotate. Note that some of the above motors may be composed of the same motor.

[0063] The common motor 70 is a single motor that rotates both the second roll 112 supported by the second holder 22 and the laminating roller 50. The common motor 70 generates power that rotates the second roll 112 and the laminating roller 50. A first transmission unit 71 is interposed between the common motor 70 and the second holder 22. The first transmission unit 71 transmits the rotational force of the common motor 70 to the second roll 112. A second transmission unit 72 is interposed between the common motor 70 and the second laminating roller 52. The second transmission unit 72 transmits the rotational force of the common motor 70 to the second laminating roller 52.

[0064] The first roll motor 81 generates power to rotate the first roll 111 supported by the first holder 21. A torque limiter 85 is interposed between the first roll motor 81 and the first holder 21. The torque limiter 85 is attached to, for example, the rotation shaft of the first holder 21. The torque limiter 85 limits the power of the first roll motor 81 and transmits it to the rotation shaft of the first holder 21.

[0065] The conveyor motor 82 generates power to rotate the first to fourth conveyor rollers 41 to 44. The power generated by the conveyor motor 82 is applied to the second roller 412, the fourth roller 422, the sixth roller 432, and the eighth roller 442.

[0066] The control unit 90 drives the common motor 70 to apply force to the second roll 112 and rotate the laminating roller 50. The control unit 90 drives the first roll motor 81 to apply force to the first roll 111, and drives the conveying motor 82 to rotate the first to fourth conveying rollers 41 to 44. The control unit 90 drives the CR motor 83 to move the carriage 31, and drives the cutting motor 84 to operate the first cutting unit 68 and the second cutting unit 69.

[0067] [First transmission part 71 and second transmission part 72] Hereinafter, clockwise and counterclockwise are defined with reference to FIG. 4. The rotating shaft 79 shown in FIG. 4 is the rotating shaft of the common motor 70. The rotating shaft 79 can rotate counterclockwise and clockwise, which is the opposite direction of the counterclockwise rotation. Note that FIG. 4 is a schematic diagram of a gear train, and does not accurately show the arrangement of the gears, the size of the gears, and the shape of the gear teeth. The common motor 70 is an example of a drive source. The rotating shaft 79 is an example of a rotating part. The counterclockwise direction is an example of a first direction. The clockwise direction is an example of a second direction.

[0068] The gear 201 is attached to a rotating shaft 79 of the common motor 70 and rotates together with the rotating shaft 79. As shown in Fig. 4 and Fig. 5(A), the first transmission unit 71 has gears 211A, 211B, 212A, 212B, 213A, 213B, 214, 215A, 215B, 216, 217, a one-way clutch 231, a torque limiter 232, and a rotary encoder 233. The second transmission unit 72 has gears 221A, 221B, 222, 223A, 223B, 224, 225, a torque limiter 234, and a rotary encoder 235.

[0069] Gears 213A and 213B are located at the same position in the up-down direction 7 and the front-rear direction 8 and have the same rotation axis, so in Fig. 4 they are depicted as if they were one gear at the same position. Gears 215A and 215B, and gears 223A and 223B are similar. In Fig. 5, "one-way", "limiter", "CW", and "CCW" respectively indicate a one-way clutch, a torque limiter, clockwise, and counterclockwise.

[0070] Gear 201 meshes with gear 211A. Gear 211B, which has the same rotation axis as gear 211A, meshes with gear 212A. Gear 212B, which has the same rotation axis as gear 212A, meshes with gears 213A and 214. Gear 214 meshes with gear 215A. Gear 213B, which has the same rotation axis as gear 213A, and gear 215B, which has the same rotation axis as gear 215A, mesh with gear 216. Gear 216 meshes with gear 217 attached to the rotation axis of second holder 22.

[0071] The one-way clutch 231 is attached to the rotating shaft of the gears 215A, 215B. The one-way clutch 231 transmits only clockwise rotational force between the gears 215A, 215B. The torque limiter 232 is attached to the rotating shaft of the gears 213A, 213B. The torque limiter 232 limits the rotational force transmitted between the gears 213A, 213B. The rotary encoder 233 is attached to the rotating shaft of the gear 216. The rotary encoder 233 outputs a signal according to the amount of rotation of the gear 216. The torque limiter 232 is an example of a first torque limiter.

[0072] The gear 201 also meshes with the gear 221A. The gear 221B, which has the same rotation axis as the gear 221A, meshes with the gear 222. The gear 222 meshes with the gear 223A. The gear 223B, which has the same rotation axis as the gear 223A, meshes with the gear 224. The gear 224 meshes with the gear 225 attached to the rotation axis of the second laminating roller 52. The torque limiter 234 is attached to the rotation axis of the gears 223A and 223B. The torque limiter 234 limits the torque transmitted between the gears 223A and 223B. The rotary encoder 233 is attached to the rotation axis of the gear 223B. The rotary encoder 233 outputs a signal according to the amount of rotation of the gear 223B. The rotary encoder 233 is an example of a detection unit. The torque limiter 234 is an example of a second torque limiter.

[0073] The rotary encoders 233 and 235 are connected to the ASIC 95 (see FIG. 3). The control unit 90 obtains the amount of rotation of the gear 216 based on the output signal of the rotary encoder 233, and obtains the amount of rotation of the gear 223B based on the output signal of the rotary encoder 235.

[0074] As shown in Fig. 5(B) and Fig. 6, when the control unit 90 rotates the common motor 70 in the forward direction, the rotating shaft 79 and the gear 201 rotate counterclockwise. The rotational force that rotates the rotating shaft 79 counterclockwise is transmitted as a rotational force that rotates the gears 211A and 211B clockwise, the gears 212A and 212B counterclockwise, the gears 213A, 213B, and 214 clockwise, and the gear 215A counterclockwise. The rotational force that rotates the gear 215A counterclockwise is not transmitted to the gear 215B due to the action of the one-way clutch 231. Therefore, the rotational force that rotates the gear 216 counterclockwise is transmitted from the gear 213B to the gear 216, and the clockwise rotational force is applied to the gear 217. The clockwise rotational force applied to gear 217 is a rotational force in a direction that rewinds second member 102.

[0075] Further, the rotational force that rotates the rotating shaft 79 counterclockwise is transmitted as a rotational force that rotates the gears 221A and 221B clockwise, the gear 222 counterclockwise, the gears 223A and 223B clockwise, the gear 224 counterclockwise, and the gear 225 clockwise. The clockwise rotational force imparted to the gear 225 is a rotational force in a direction that causes the second member 102 to be pulled out.

[0076] As shown in FIG. 5(C) and FIG. 7, when the control unit 90 rotates the common motor 70 in the reverse direction, the rotating shaft 79 and the gear 201 rotate clockwise. The rotational force that rotates the rotating shaft 79 clockwise is transmitted as a rotational force that rotates the gears 211A and 211B counterclockwise, the gears 212A and 212B counterclockwise, the gears 213A and 214 counterclockwise, and the gear 215A clockwise. Here, the rotational force is transmitted to the gear 215B by the action of the one-way clutch 231 between the gears 215A and 215B. Therefore, the gear 215B rotates clockwise. The rotational force that rotates the gear 215B clockwise is transmitted as a rotational force that rotates the gear 216 counterclockwise and the gears 213B and 217 clockwise. The clockwise rotational force applied to gear 217 is a rotational force in a direction that rewinds second member 102. Furthermore, a counterclockwise rotational force is transmitted to gear 213A, and a clockwise rotational force is transmitted to gear 213B, so that slip occurs in torque limiter 232.

[0077] Furthermore, the rotational force that rotates the rotating shaft 79 clockwise rotates the gears 221A and 221B counterclockwise, the gear 222 clockwise, and the gear 223A counterclockwise. The rotational force of the gear 223A is transmitted by the torque limiter 234 as a rotational force that rotates the gear 223B counterclockwise, the gear 224 clockwise, and the gear 225 counterclockwise. The counterclockwise rotational force imparted to the gear 225 is a rotational force in a direction that rewinds the second member 102.

[0078] In this way, the first transmission unit 71 transmits the counterclockwise rotational force of the rotating shaft 79 to the second roll 112 as a rotational force in a direction to rewind the second member 102 limited by the torque limiter 232. Also, the first transmission unit 71 transmits the clockwise rotational force of the rotating shaft 79 to the second roll 112 as a rotational force in a direction to rewind the second member 102 without limiting the rotational force by the one-way clutch 231. The second transmission unit 72 transmits the counterclockwise rotational force of the rotating shaft 79 to the laminating roller 50 as a rotational force in a direction to pull out the second member 102 limited by the torque limiter 234, and transmits the clockwise rotational force of the rotating shaft to the laminating roller 50 as a rotational force in a direction to rewind the second member 102 limited by the torque limiter 234.

[0079] The first transmission section 71 has a first transmission path 73 and a second transmission path 74 that transmit the rotational force of the rotating shaft 79 to the second roll 112. The first transmission path 73 leads to the gear 216 via the gear 212B, the gear 213A, the torque limiter 232, and the gear 213B. The second transmission path 74 leads to the gear 216 via the gear 212B, the gears 214, 215A, the one-way clutch 231, and the gear 215B. The first transmission path 73 has a torque limiter 232 on the path. The second transmission path 74 does not have a torque limiter on the path. When the rotating shaft 79 rotates counterclockwise, the rotational force limited by the torque limiter 232 is transmitted to the second roll 112 via the first transmission path 73. When the rotary shaft 79 rotates clockwise, the rotational force that is not limited by the torque limiter is transmitted to the second roll 112 via the second transmission path 74 .

[0080] The first transmission unit 71 and the second transmission unit 72 will be described in detail with reference to Figures 6 and 7. As shown in Figures 6 and 7, the one-way clutch 231 has a motor side portion 231A that rotates together with the gear 215A and a roll side portion 231B that rotates together with the gear 215B. The torque limiter 232 has a motor side portion 232A that rotates together with the gear 213A and a roll side portion 232B that rotates together with the gear 213B. The torque limiter 234 has a motor side portion 234A that rotates together with the gear 223A and a roller side portion 234B that rotates together with the gear 223B.

[0081] 6 and 7 also show the second roll 112, the first laminating roller 51, the second laminating roller 52, the intermediate roller 239, and the second member 102. The second member 102 is pulled out from the second roll 112, passes through the intermediate roller 239, and enters between the first laminating roller 51 and the second laminating roller 52.

[0082] Hereinafter, a state in which the second roll 112 and the laminating roller 50 can rotate independently at a free speed is referred to as a "free state". For example, when the second member 102 is not connected between the second roll 112 and the laminating roller 50, it is in the free state. The peripheral speed on the circumference of the second roll 112 when the common motor 70 rotates forward in the free state is V1a, and the conveying force of the second roll 112 at this time is F1a. The peripheral speed on the circumference of the second roll 112 when the common motor 70 rotates reverse in the free state is V1b, and the conveying force of the second roll 112 at this time is F1b. The peripheral speed on the circumference of the laminating roller 50 when the common motor 70 rotates forward or reverse in the free state is V2, and the conveying force of the laminating roller 50 at this time is F2.

[0083] The conveying force F1a is a rotational force restricted by the torque limiter 232. The conveying force F1b is a rotational force not restricted by the torque limiter. The conveying force F2 is a rotational force restricted by the torque limiter 234. Also, while the peripheral speed V2 and the conveying force F2 are constant, the peripheral speeds V1a, V1b and the conveying forces F1a, F1b vary depending on the amount of the second member 102 wound around the second roll 112 (the remaining amount of the second member 102). Here, it is described assuming that the rotational force and the rotational speed when the common motor 70 rotates forward are the same as those when it rotates backward, but the rotational force and the rotational speed may be changed between when it rotates forward and when it rotates backward.

[0084] The first transmission part 71 and the second transmission part 72 are configured to satisfy the following conditions. (Condition 1) V2 < the minimum value of V1a (Condition 2) F2 > the maximum value of F1a (Condition 3) V2 < the minimum value of V1b (Condition 4) F2 < the minimum value of F1b

[0085] When the common motor 70 rotates forward, V2 < V1a and F2 > F1a are satisfied, and since the conveying force of the laminating roller 50 is greater than the conveying force of the second roll 112, the second member 102 is conveyed in the pulling-out direction at the speed V2. At this time, a clockwise rotational force is applied to the second roll 112 via the first transmission part 71, and a counterclockwise rotational force is applied from the laminating roller 50 via the second member 102, but the second roll 112 actually rotates counterclockwise. For this reason, actually, the gear 216 rotates clockwise, and the gears 213B, 215B rotate counterclockwise.

[0086] At this time, in the torque limiter 232, the motor-side part 232A rotates clockwise, and the roller-side part 234B rotates counterclockwise. For this reason, a rotational force is generated in the direction to suppress the rotation of the second roll 112 in the pulling-out direction, and the second member 102 is conveyed in the pulling-out direction while maintaining the tension by the conveying force F1a.

[0087] In the one-way clutch 231, both the motor-side portion 231A and the roll-side portion 231B rotate counterclockwise. However, since the speed at which the second member 102 is pulled out is slow and the motor-side portion 231A rotates faster than the roll-side portion 231B, the one-way clutch 231 does not transmit the rotational force.

[0088] When the common motor 70 reverses, V2 < V1b and F2 < F1b are satisfied, and since the peripheral speed of the second roll 112 is greater than the peripheral speed of the laminating roller 50, the second member 102 is conveyed in the rewinding direction at the speed V1b. At this time, a counterclockwise rotational force is applied to the laminating roller 50 via the second transmission portion 72, and a counterclockwise rotational force is applied from the second roll 112 via the second member 102. For this reason, the laminating roller 50 rotates at a speed V1b that is faster than the speed V2 due to the rotational force applied via the second transmission portion 72.

[0089] At this time, in the torque limiter 234, the motor-side portion 234A rotates counterclockwise at a slow speed, and the roller-side portion 234B rotates counterclockwise at a fast speed. For this reason, a rotational force is generated in a direction to suppress the rotational force of the laminating roller 50 in the rewinding direction, and the second member 102 is conveyed in the rewinding direction while maintaining the tension due to the conveying force F2.

[0090] In this way, the laminating apparatus 1 is configured such that when the rotating shaft 79 rotates counterclockwise, the second member 102 is conveyed in the direction of being pulled out from the second roll 112, and when the rotating shaft 79 rotates clockwise, the second member 102 is conveyed in the direction of being rewound onto the second roll 112. Specifically, the first transmission portion 71 and the second transmission portion 72 are configured such that the second member 102 is conveyed as described above.

[0091] Furthermore, the laminating apparatus 1 is configured so that when the amount of the second member 102 wound around the second roll 112 is at a minimum and the rotating shaft 79 rotates clockwise, a rotational force is applied to the second roll 112 and the laminating roller 50 such that the circumferential speed of the second member 102 wound around the second roll 112 is faster than the circumferential speed of the laminating roller 50. Specifically, the first transmission section 71 and the second transmission section 72 are configured so as to satisfy the above-mentioned relationship in magnitude between the speeds. However, the relationship in magnitude between the speeds should be satisfied when the second roll 112 and the laminating roller 50 can rotate at free speeds independently of each other (for example, when it is assumed that the second member 102 is not connected between the second roll 112 and the laminating roller 50).

[0092] [Lamination process by control unit 90] The lamination process by the control unit 90 will be described with reference to FIG. 8. The lamination process shown in FIG. 8 is executed by the control unit 90 executing a program stored in the RAM 93. The control unit 90 executes the lamination process, for example, when it receives an instruction to execute the lamination process from the operation unit 12. When the control unit 90 executes the lamination process, the lamination device 1 operates as shown in FIG. 9 to FIG. 11. Note that only the main elements of the lamination device 1 are shown in FIG. 9 to FIG. 11. Since the third conveyor roller 43 and the fourth conveyor roller 44 play a small role in the lamination process, the following description of the third conveyor roller 43 and the fourth conveyor roller 44 will be omitted.

[0093] 9(A) shows an initial state before lamination processing is performed. In the initial state, the control unit 90 stops the first roll 111, the second roll 112, and the laminating roller 50. In the initial state, the leading end of the first member 101 pulled out from the first roll 111 is held by the first conveying roller 41, and the leading end of the second member 102 pulled out from the second roll 112 is held by the laminating roller 50. In addition, the laminating roller 50 holds the remainder of the first member 101 generated in the previous laminating processing.

[0094] When starting to use the laminating device 1, a user attaches the first roll 111 to the first holder 21, attaches the second roll 112 to the second holder 22, and causes the leading end of the first member 101 pulled out from the first roll 111 to be gripped by the first conveying roller 41, and causes the leading end of the second member 102 pulled out from the second roll 112 to be gripped by the laminating roller 50. This brings the laminating device 1 into the initial state shown in FIG. 9(A).

[0095] [Skewing correction of the first member 101 and the second member 102] At the beginning of the lamination process, the control unit 90 corrects the skew of the first member 101 and the second member 102 (S11). In S11, the control unit 90 drives the conveying motor 82 to apply a force acting in a direction to pull out the first member 101 to the first conveying roller 41 (see FIG. 9(B) and FIG. 12(A)). At this time, a force acting in a direction to rewind the first member 101 is applied from the first roll motor 81 to the first roll 111. However, since the latter force is smaller than the former force, the first member 101 is pulled out toward the downstream side of the conveying path 15 (hereinafter, this operation is referred to as the "pulling out operation").

[0096] Following the pull-out operation, the control unit 90 drives the conveying motor 82 in the opposite direction to apply a force acting in a direction to rewind the first member 101 to the first conveying roller 41 (see FIG. 9(C) and FIG. 12(B)). At this time, a force acting in a direction to rewind the first member 101 is applied from the first roll motor 81 to the first roll 111. As a result, the first member 101 is rewound onto the first roll 111 (hereinafter, this operation will be referred to as the "rewinding operation").

[0097] In the pulling-out operation, the control unit 90 pulls out the first member 101 until the leading end of the first member 101 reaches the position of the member sensor 61 based on an output signal from the member sensor 61. In the rewinding operation, the control unit 90 rewinds the first member 101 by a predetermined amount based on an output signal from a rotary encoder (not shown) attached to the rotation shaft of the first conveyor roller 41. As skew correction control for the first member 101, the control unit 90 executes the pulling-out operation and the rewinding operation of the first member 101 at least once each.

[0098] In addition to the skew correction control of the first member 101, in S11, the control unit 90 rotates the common motor 70 in the forward direction to apply a force acting in a direction to pull out the second member 102 to the laminating roller 50 (see FIG. 9(B)). At this time, a force acting in a direction to rewind the second member 102 is applied from the common motor 70 to the second roll 112. However, since the latter force is smaller than the former force, the second member 102 is pulled out toward the laminating roller 50.

[0099] Following the pull-out operation of the second member 102, the control unit 90 reverses the common motor 70 to apply a force acting in a direction to rewind the second member 102 to the laminating roller 50 (see FIG. 9(C)). At this time, a force acting in a direction to rewind the second member 102 is also applied from the common motor 70 to the second roll 112. As a result, the second member 102 is rewound onto the second roll 112.

[0100] In the pulling-out operation of the second member 102, the control unit 90 pulls out the second member 102 until the leading end of the second member 102 reaches the position of the member sensor 63 based on the output signal of the member sensor 63. In the rewinding operation of the second member 102, the control unit 90 rewinds the second member 102 by a predetermined amount based on the output signal of the rotary encoder 233 included in the second transmission unit 72. As the skew correction control for the second member 102, the control unit 90 executes the pulling-out operation and the rewinding operation of the second member 102 at least once each.

[0101] When a user causes the laminating roller 50 to grip the leading end of the second member 102 pulled out from the second roll 112, the second member 102 may be gripped by the laminating roller 50 in an oblique direction, as shown in Fig. 12(A). At this time, the skew of the second member 102 can be corrected by alternately performing a pulling-out operation (Fig. 12(A)) and a rewinding operation (Fig. 12(B)) for the second member 102. In a similar manner, the skew of the first member 101 can also be corrected.

[0102] In S11, the control unit 90 performs in parallel the skew correction of the first member 101 and the skew correction of the second member 102. Note that the control unit 90 may perform either one of the skew correction of the first member 101 or the skew correction of the second member 102 first, and then perform the other.

[0103] [The first member 101 is gripped by the second conveyor roller 42] Next, the control unit 90 causes the second conveying roller 42 to grip the first member 101 (S12). In S12, the control unit 90 stops driving the common motor 70, and stops the laminating roller 50 and the second roll 112. Thereafter, the control unit 90 drives the conveying motor 82 to apply a force acting in a direction to pull out the first member 101 to the first conveying roller 41. At this time, a force acting in a direction to rewind the first member 101 is applied from the first roll motor 81 to the first roll 111. Since the latter force is smaller than the former force, the first member 101 is pulled out toward the downstream side of the conveying path 15 while maintaining a predetermined tension. When the leading end of the first member 101 reaches the second conveying roller 42, the second conveying roller 42 grips the first member 101 (see FIG. 9(D)).

[0104] [Transportation of the first member 101 and image recording] Next, the control unit 90 causes the first member 101 to be conveyed (S13). In S13, the control unit 90 drives the conveying motor 82 to rotate the first conveying roller 41 and the second conveying roller 42, and causes the first conveying roller 41 and the second conveying roller 42 to convey the first member 101 (see FIG. 10B).

[0105] Next, the control unit 90 stops the transport of the first member 101 and drives the image recording unit 30 to record an image on the first member 101 (S14). In S14, the control unit 90 stops the drive of the transport motor 82 and stops the rotation of the first transport roller 41 and the second transport roller 42, thereby stopping the first member 101. While the first member 101 is stopped, ink is ejected from the recording head 32 of the image recording unit 30 onto the recording surface 107 of the first member 101. As a result, an image is recorded on a part of the recording surface 107 of the first member 101 (see FIG. 10C).

[0106] Next, the control unit 90 judges whether or not to continue recording the image (S15). When the control unit 90 judges to continue recording the image (S15: Yes), the process proceeds to S13. The control unit 90 repeatedly executes S13 and S14 until it judges No in S15. As a result, images are recorded on the first member 101 in sequence from the downstream side to the upstream side in the conveying direction. Note that in FIG. 10(B) and other figures, the hatched area on the first member 101 indicates a portion on which the image recording unit 30 has recorded an image in one image recording.

[0107] [Driving the Laminating Roller 50] After executing S13, when the control unit 90 determines that the first member 101 has reached the laminating roller 50 based on the output signal of the member sensor 62, it starts driving the laminating roller 50. After that, the control unit 90 drives the common motor 70 to apply a force acting in a direction to pull out the second member 102 to the laminating roller 50. At this time, a force acting in a direction to rewind the second member 102 is applied from the common motor 70 to the second roll 112 (see FIG. 10(D)). After that, the laminating roller 50 bonds the recording surface 107 of the first member 101 and the laminating surface 109 of the second member 102 together.

[0108] [Cutting by first cutting unit 68] When the control unit 90 determines not to continue recording of the image in S15 (S15: No), the process proceeds to S16. In this case, the control unit 90 transports the first member 101 until the cutting position upstream of the position where the image of the first member 101 was recorded reaches under the first cutting unit 68 (S16). In S16, the control unit 90 performs the same process as S13. However, while the laminating roller 50 is rotating, the first member 101 is transported by both the force from the second transport roller 42 and the force from the laminating roller 50 (see FIG. 11(A)).

[0109] Next, the control unit 90 causes the first cutting unit 68 to cut the first member 101 (S17). In S17, the control unit 90 drives the cutting motor 84 to operate the first cutting unit 68. The first cutting unit 68 cuts the first member 101 at the cutting position (see FIG. 11(B)).

[0110] [Cutting by second cutting portion 69] Next, the control unit 90 transports the bonded first member 101 and second member 102 (S18). In S18, the control unit 90 drives the common motor 70 to transport the bonded first member 101 and second member 102 until the cutting position of the bonded first member 101 and second member 102 reaches under the second cutting unit 69.

[0111] After executing S18, the control unit 90 stops the first conveyor roller 41, the second conveyor roller 42, the laminating roller 50, and the second roll 112. At this point, the cutting position of the first member 101 and the second member 102 after lamination is located under the second cutting unit 69.

[0112] Next, the control unit 90 causes the second cutting unit 69 to cut the bonded first member 101 and second member 102 (S19). In S19, the control unit 90 drives the cutting motor 84 to operate the second cutting unit 69. The second cutting unit 69 cuts the bonded first member 101 and second member 102 at the cutting position (see FIG. 11(C)).

[0113] [Rewinding the first member 101] Next, the control unit 90 causes the first member 101 to be rewound onto the first roll 111 (S20). In S20, the control unit 90 drives the conveying motor 82 in the reverse direction, and rotates the first conveying roller 41 and the second conveying roller 42 in the reverse direction. The first conveying roller 41 and the second conveying roller 42 apply a force in a direction to wind up the first member 101. At this time, a force acting in a direction to wind up the first member 101 is applied from the first roll motor 81 to the first roll 111. Therefore, the first member 101 is conveyed toward the first roll 111 and rewound onto the first roll 111 (see FIG. 11(D)).

[0114] [Effects of the embodiment] As described above, the laminating device 1 according to this embodiment includes the first holder 21 (first support section), the second holder 22 (second support section), the image recording section 30, the laminating roller 50, and the common motor 70 (drive source). The common motor 70 is a single motor that rotates both the second roll 112 and the laminating roller 50. Therefore, according to the laminating device 1 according to this embodiment, the second roll 112 and the laminating roller 50 are operated by the single common motor 70, and the cost of the laminating device 1 can be reduced.

[0115] Furthermore, when the rotating shaft 79 (rotating portion) of the common motor 70 rotates counterclockwise (first direction), the second member 102 is transported in a direction to be pulled out from the second roll 112, and when the rotating shaft 79 rotates clockwise (second direction), the second member 102 is transported in a direction to be rewound onto the second roll 112. Therefore, by rotating the rotating shaft 79 clockwise and counterclockwise, an operation to pull out the second member 102 from the second roll 112 and an operation to rewind the second member 102 onto the second roll 112 can be performed, and skew of the second member 102 can be corrected. Therefore, after the second member 102 is brought into a state where it is not skewed, it is possible to obtain a laminated finished product 100 with little misalignment by bonding it to the first member 101 on which an image is recorded.

[0116] The laminating apparatus 1 also includes a first transmission unit 71 and a second transmission unit 72. The first transmission unit 71 transmits the counterclockwise and clockwise rotational forces of the rotating shaft 79 to the second roll 112 as rotational forces in a direction to unwind the second member 102. The second transmission unit 72 transmits the counterclockwise rotational force of the rotating shaft 79 to the laminating roller 50 as rotational force in a direction to pull out the second member 102, and transmits the clockwise rotational force of the rotating shaft 79 to the laminating roller 50 as rotational force in a direction to unwind the second member 102. Therefore, when the rotating shaft 79 rotates counterclockwise, it applies rotational forces in opposite directions to the second roll 112 and the laminating roller 50 to apply tension to the second member 102, and when the rotating shaft 79 rotates clockwise, it applies rotational forces in the same direction to the second roll 112 and the laminating roller 50 to unwind the second member 102.

[0117] Further, the first transmission unit 71 has a first transmission path 73 and a second transmission path 74. The first transmission path 73 has a torque limiter 232 on the path, and the second transmission path 74 has no torque limiter on the path. When the rotating shaft 79 rotates counterclockwise, the rotational force limited by the torque limiter 232 is transmitted to the second roll 112 via the first transmission path 73. When the rotating shaft 79 rotates clockwise, the rotational force not limited by the torque limiter is transmitted to the second roll 112 via the second transmission path 74. Therefore, the first transmission unit 71 can provide the counterclockwise rotational force of the rotating shaft 79 to the second roll 112 while being limited by the torque limiter 232, and provide the clockwise rotational force of the rotating shaft 79 to the second roll 112 without being limited by the torque limiter.

[0118] Further, a rotary encoder 233 (detection unit) is attached to the rotating shaft of the gear 216. The rotary encoder 233 may be provided at least one of downstream of the torque limiter 232 in the first transmission path 73 and downstream of the one-way clutch 231 in the second transmission path 74. The rotary encoder 233 can detect the amount of rotation of a member in the first transmission unit 71.

[0119] Further, a torque limiter 234 is attached to the rotating shaft of the gears 223A and 223B. The torque limiter 234 may be provided at any position in the second transmission unit 72. Therefore, the rotational force limited by the torque limiter 234 can be applied to the laminating roller 50. Further, the first transmission unit 71 and the second transmission unit 72 include gears. Therefore, the rotational force of the rotating shaft 79 can be transmitted to the second roll 112 and the laminating roller 50 by the gears.

[0120] Furthermore, when the rotating shaft 79 rotates clockwise with the amount of the second member 102 wound around the second roll 112 at a minimum, a rotational force is applied to the second roll 112 and the laminating roller 50 such that the circumferential speed of the second member 102 wound around the second roll 112 is faster than the circumferential speed of the laminating roller 50. Therefore, when the rotating shaft 79 rotates counterclockwise, the second member 102 can be unwound while tension is applied to the second member 102.

[0121] Further, the first transmission section 71 has a torque limiter 232 (first torque limiter), and transmits the counterclockwise rotational force of the rotating shaft 79 to the second roll 112 via the torque limiter 232, and transmits the clockwise rotational force of the rotating shaft 79 to the second roll 112 without passing through the torque limiter 232. The second transmission section 72 has a torque limiter 234 (second torque limiter), and transmits the counterclockwise and clockwise rotational forces of the rotating shaft 79 to the laminating roller 50 via the torque limiter 234. Therefore, the counterclockwise rotational force of the rotating shaft 79 can be limited by the torque limiter 232 and applied to the second roll 112, and can be limited by the torque limiter 234 and applied to the laminating roller 50. Further, the clockwise rotational force of the rotating shaft 79 can be applied to the second roll 112 without being limited by the torque limiter 232, and can be limited by the torque limiter 234 and applied to the laminating roller 50.

[0122] Furthermore, the control unit 90 of the laminating device 1 executes the pulling out operation and the rewinding operation at least once each as skew correction control for the second member 102. This makes it possible to correct the skew of the second member 102. Therefore, after the second member 102 is put into a state where it is not skewed, it is possible to obtain a distortion-free laminated finished product 100 by bonding it to the first member 101 on which an image is recorded.

[0123] The laminating apparatus 1 also includes a member sensor 63 in front of the laminating roller 50 (downstream of the laminating roller 50) in the front-rear direction 8. The control unit 90 switches between the pull-out operation and the rewinding operation based on an output signal from the member sensor 63. Therefore, in response to the member sensor 63 detecting the second member 102, the control unit 90 can switch between the pull-out operation and the rewinding operation.

[0124] [Variations] Various modifications can be made to the laminating device 1 according to the above embodiment. The second transmission section 75 shown in Fig. 13 and Fig. 14(A) has gears 226A and 226B instead of the gear 222, and has gears 227A, 227B, and 228, and one-way clutches 236 and 237. In the second transmission section 75, the gear 221B meshes with the gears 226A and 227A. The gear 227B, which has the same rotation axis as the gear 227A, meshes with the gear 228. The gear 226B, which has the same rotation axis as the gear 226A, and the gear 228 mesh with the gear 223A.

[0125] One-way clutch 236 is attached to the rotating shaft of gears 226A and 226B. One-way clutch 236 transmits only counterclockwise rotational force between gears 226A and 226B. One-way clutch 237 is attached to the rotating shaft of gears 227A and 227B. One-way clutch 237 transmits only clockwise rotational force between gears 227A and 227B.

[0126] As shown in FIG. 14B and FIG. 15, when the control unit 90 rotates the common motor 70 in the forward direction, the rotating shaft 79 and the gear 201 rotate counterclockwise. The rotational force that rotates the rotating shaft 79 counterclockwise is transmitted as a rotational force that rotates the gears 221A and 221B clockwise and the gears 226A, 226B, and 227A counterclockwise. The rotational force that rotates the gear 227A counterclockwise is not transmitted to the gear 227B due to the action of the one-way clutch 237. Therefore, the rotational force that rotates the gear 223A clockwise is transmitted from the gear 226B to the gear 223A. This rotational force is transmitted as a rotational force that rotates the gear 223B clockwise and the gear 224 counterclockwise, and the clockwise rotational force is applied to the gear 225. The clockwise rotational force applied to the gear 225 is a rotational force in a direction that pulls out the second member 102.

[0127] As shown in FIG. 14C and FIG. 16, when the control unit 90 rotates the common motor 70 in the reverse direction, the rotating shaft 79 and the gear 201 rotate clockwise. The rotational force that rotates the rotating shaft 79 clockwise is transmitted as a rotational force that rotates the gears 221A and 221B counterclockwise, the gears 226A, 227A, and 227B clockwise, and the gear 228 counterclockwise. The rotational force that rotates the gear 226A clockwise is not transmitted to the gear 226B due to the action of the one-way clutch 236. Therefore, the rotational force that rotates the gear 223A clockwise is transmitted from the gear 228 to the gear 223A. This rotational force is transmitted as a rotational force that rotates the gear 223B clockwise and the gear 224 counterclockwise, and the clockwise rotational force is applied to the gear 225.

[0128] The laminating device according to the modified example is configured so that, when the rotating shaft 79 rotates counterclockwise, the second member 102 is transported in a direction in which it is pulled out from the second roll 112, and, when the rotating shaft 79 rotates clockwise, the second member 102 is transported in a direction in which it is rewound onto the second roll 112. Specifically, the first transmission unit 71 and the second transmission unit 75 are configured so that the second member 102 is transported as described above.

[0129] In this way, the second transmission unit 75 transmits the counterclockwise and clockwise rotational forces of the rotating shaft 79 to the laminating roller 50 as rotational forces in a direction to pull out the second member 102. Therefore, when the rotating shaft 79 rotates clockwise, it is possible to apply tension to the second member 102 by applying rotational forces in opposite directions to the second roll 112 and the laminating roller 50.

[0130] 17 has gears 229A and 229B instead of the gear 222, and has a one-way clutch 238. The one-way clutch 238 is attached to the rotating shaft of the gears 229A and 229B. The one-way clutch 238 transmits only the counterclockwise rotational force between the gears 229A and 229B. The one-way clutch 238 is an example of a transmission control section that does not transmit the rotational force from the rotating shaft 79 to the laminating roller 50 when the rotating shaft 79 rotates clockwise.

[0131] 17, when the rotating shaft 79 rotates counterclockwise, a rotational force in the rewinding direction is applied to the second roll 112, and the rotational force is not transmitted to the laminating roller 50, thereby making it possible to rewind the second member 102. Note that the second transmitting unit may have, as a transmission control unit, a mechanism for blocking the transmission of the rotational force, such as a planetary gear, instead of the one-way clutch 238.

[0132] The second transmission unit of the laminating device according to the modified example may have a lock unit 55 shown in FIG. 18(A) and FIG. 18(B). In FIG. 18(A) and FIG. 18(B), the rotational force that rotates the rotation shaft 79 of the common motor 70 is transmitted to the second laminating roller 52 through a transmission path including gears 251, 252, and 253. The gear 251 meshes with the gear 252. The gear 252 meshes with the gear 253 having the same rotation shaft as the second laminating roller 52. A torque limiter 254 is attached to the rotation shaft of the gear 251. A plurality of protrusions 53 are located on the outer periphery of the second laminating roller 52. The lock unit 55 has a main body 551, a spring 552, and a solenoid 553, and is rotatable around the shaft 554. The lock portion 55 is biased by a spring 552 in a direction away from the second laminating roller 52. Note that gear teeth are omitted in Figures 18 and 19.

[0133] 18(A), the solenoid 553 is in a contracted state, and the main body 551 of the locking portion 55 is biased by the spring 552 to a position where it does not engage with the protrusion 53 of the second laminating roller 52. When the common motor 70 rotates in the reverse direction in the unlocked state and the rotating shaft 79 rotates clockwise, the gear 251 rotates clockwise, the gear 252 rotates counterclockwise, and the gear 253 and the second laminating roller 52 rotate clockwise.

[0134] 18(B), the solenoid 553 is in an extended state, and the main body 551 of the locking unit 55 approaches the second laminating roller 52 against the force of the spring 552. At this time, the main body 551 engages with the protrusion 53 of the second laminating roller 52, preventing (locking) the rotation of the second laminating roller 52. When the common motor 70 rotates in the reverse direction in the locked state and the rotating shaft 79 rotates clockwise, slippage occurs in the torque limiter 254, and the second laminating roller 52 does not rotate. In this way, the locking unit 56 locks the rotation of the laminating roller 50 when the rotating shaft 79 rotates clockwise.

[0135] The second transmission unit of the laminating device according to the modified example may have a lock unit 56 shown in FIG. 19(A) and FIG. 19(B). In FIG. 19(A) and FIG. 19(B), the rotational force that rotates the rotating shaft 79 of the common motor 70 is transmitted to the second laminating roller 52 through a transmission path including a gear 251, a planetary differential gear 261, and a gear 253. The lock unit 56 has a hook 561 in addition to a main body 551, a spring 552, and a solenoid 553. As shown in FIG. 19(C) and FIG. 19(D), the planetary differential gear 261 has a sun gear 263, a planetary gear 264, and an inner gear 265. A hook 262 is located on the outer periphery of the inner gear 265.

[0136] 19(A), the solenoid 553 is in a contracted state, and the main body 551 of the locking portion 56 is biased by the spring 552, and is located at a position where the hook 561 engages with the planetary gear 264. When the common motor 70 rotates in the reverse direction in the unlocked state and the rotating shaft 79 rotates clockwise, the gear 251 rotates clockwise, the gear 252 rotates counterclockwise, and the gear 253 and the second laminating roller 52 rotate clockwise.

[0137] 19(B), the solenoid 553 is in an extended state, and the main body 551 of the locking portion 55 approaches the planetary differential gear 261 against the force of the spring 552. At this time, the main body 551 engages with the hook 262 of the internal gear 265 and prevents (locks) the rotation of the internal gear 265, so that the planetary gear 264 rotates freely. When the common motor 70 rotates in the reverse direction in the locked state and the rotating shaft 79 rotates clockwise, the planetary gear 264 rotates freely and the second laminating roller 52 does not rotate. In this way, the locking portion 56 locks the rotation of the laminating roller 50 when the rotating shaft 79 rotates clockwise.

[0138] 18 and 19 has locking units 55 and 56 that lock the rotation of the laminating roller 50 when the rotating shaft 79 rotates clockwise. Therefore, when the rotating shaft 79 rotates clockwise, a rotational force in the rewinding direction is applied to the second roll 112, and the rotation of the laminating roller 50 is locked, so that the second member 102 can be rewound.

[0139] The first transmission unit and the second transmission unit of the laminating device according to the modified example may include a belt that transmits a rotational force. The first transmission unit 77 shown in Fig. 20 has pulleys 241 and 242 and a belt 243 instead of the gear 217. The pulley 241 has the same rotation axis as the gear 216. The pulley 242 has the same rotation axis as the second holder 22. The belt 243 is hung between the pulleys 241 and 242.

[0140] 20 has pulleys 244, 245, and a belt 246 instead of the gear 225. The pulley 244 has the same rotation axis as the gear 224. The pulley 244 has the same rotation axis as the second laminating roller 52. The belt 246 is hung between the pulleys 244, 245. The first transmission unit 77 and the second transmission unit 78 can also transmit the rotation force of the rotation axis 79 to the second roll 112 and the laminating roller 50 by the belts 243, 246.

[0141] The laminating device according to the modified example may include a width direction sensor that detects the width direction position of the second member 102. In Fig. 21(A), a width direction sensor 64 is located on one side in the width direction of the second member 102 pulled out from the second roll 112. The width direction sensor 64 outputs a plurality of signals indicating whether or not the second member 102 is present within a predetermined range. In Fig. 21(B), width direction sensors 65 and 66 are located on one and the other sides in the width direction of the second member 102 pulled out from the second roll 112. The width direction sensors 65 and 66 each output one signal indicating whether or not the second member 102 is present at a predetermined position.

[0142] The control unit 90 detects the skew state of the second member 102 based on the width direction sensor 64 (or the output signal of the width direction sensors 65, 66), and controls the execution of the pull-out operation and the rewinding operation based on the detected skew state. For example, the control unit 90 repeatedly executes the pull-out operation and the rewinding operation of the second member 102 until it is determined that the second member 102 is not skewed. Therefore, according to the laminating device of the modified example, the skew of the second member 102 can be suitably corrected according to the detected skew state of the second member 102. Specifically, when the skew of the second member 102 is small, the skew correction control is completed in a short time, and even when the skew of the second member 102 is large, the skew of the second member 102 can be reliably corrected.

[0143] The laminating device according to the modified example may be one that bonds a first member 101 having a predetermined length and on which an image is recorded, and a second member 102 drawn from a second roll 112. The laminating device 2 according to the modified example shown in FIG. 22 includes a supply unit 25 that supplies the first member 101 instead of the first holder 21. The supply unit 25 includes a cassette 26 that stores the first member 101 of a predetermined length, and a feed roller 27 that feeds the first member 101 stored in the cassette 26 toward the conveying path 15. The laminating device 2 according to the modified example can also operate the second roll 112 and the laminating roller 50 with a single common motor 70, thereby reducing the cost of the laminating device 2.

[0144] The laminating device according to the modified example may have a first transmission unit and a second transmission unit having a different configuration from the first transmission unit and the second transmission unit described above. For example, the detailed configurations of the first transmission unit and the second transmission unit (e.g., the number of gears, the gear ratio, the branching state of the gear train, the positions of the one-way clutch and the torque limiter, etc.) may be different from those of the first transmission unit and the second transmission unit described above. Furthermore, the first transmission unit and the second transmission unit may have a planetary gear or a mechanism including a solenoid instead of a one-way clutch as a means for not transmitting a rotational force in a specific direction.

[0145] The laminating device according to the modified example does not necessarily have to include the third conveyor roller 43 and the fourth conveyor roller 44. In the laminating device according to the modified example, the second conveyor roller 42 may be located at the position of the third conveyor roller 43 or the position of the fourth conveyor roller 44.

[0146] The laminating device according to the modified example does not need to include the second cutting unit 69. In this case, the member obtained by bonding the first member 101 and the second member 102 together is discharged from the discharge port 14 in an uncut state. The user cuts the discharged member outside the laminating device, for example, using scissors.

[0147] In the embodiment and the modified example of the present invention, the common motor 70 is a single motor that rotates both the second roll 112 supported by the second holder 22 and the laminating roller 50, but this is not limited to the above. For example, the first roll motor 81 may be the common motor 70, the first roll 111 may be the second roll 112, the laminating roller 50 may be the first conveyor roller 41, and the first roll motor 81 may be a single motor that rotates both the first roll 111 supported by the first holder 21 and the first conveyor roller 41.

[0148] The image recording unit 30 of the laminating device 1 has a recording head 32 that ejects ink and records images by a so-called serial inkjet method, but the configuration of the image recording unit 30 is not limited to this. The recording unit of the laminating device according to the modified example may have a fixed inkjet recording head and record images by a so-called line head method, for example. The recording unit of the laminating device according to the modified example may record images by a so-called thermal head method. The recording unit of the laminating device according to the modified example may record images by a so-called laser method in which toner is fixed to the recording medium using laser light.
