[0007] There is a laminating apparatus that laminates a first member pulled out from a first reel, a second member that is conveyed, and a third member that is conveyed after the second member by a laminating unit including a pair of rollers. When the first member pulled out from the first reel has an adhesive layer on the laminating surface, if there is no member in contact with the laminating surface of the first member, the adhesive layer of the first member may come into contact with one of the rollers of the laminating unit, sometimes causing abnormal operation in the laminating apparatus.

[0008] The present invention has been made in view of the above circumstances, and an object thereof is to provide an apparatus that can reduce contact between the adhesive layer of the laminated member and the components in the laminating unit.

[0009] Technical Means for Solving the Problems

[0010] (1) The laminating apparatus of the present invention includes: a laminating unit that overlaps and laminates a plurality of members; a conveying unit that conveys the plurality of members to the laminating unit; and a control unit. The control unit causes the laminating unit to perform lamination in a state where a part including the rear end of the first member, a part including the front end of the second member, and a part including the front end of the third member overlap.

[0011] According to the above lamination device, when the first member has an adhesive layer on the bonding surface and the second member and the third member are bonded to the bonding surface of the first member, by performing bonding such that a part of the second member including the rear end overlaps with a part of the third member including the front end located upstream of the second member in the conveying direction, no gap is generated between the second member and the third member, and contact between the adhesive layer of the first member and the components within the bonding portion can be reduced.

[0012] (2) Preferably, the above lamination device further includes a first sensor unit for detecting the rear end of the second member, and the control unit stops the rear end of the second member at a position where a predetermined conveyance amount has been conveyed from the position where the rear end of the second member is detected by the first sensor unit.

[0013] (3) Preferably, the above lamination device further includes a second sensor unit for detecting the front end of the third member, and the control unit starts the operation of the bonding portion after conveying a predetermined conveyance amount from the position where the front end of the third member is detected by the second sensor unit.

[0014] (4) Preferably, the above bonding portion may include a pair of rollers, and the pair of rollers includes a first roller and a second roller.

[0015] (5) Preferably, the above bonding portion may bond the first member, the second member, and the third member in a state where they are overlapped in the order of the first member, the second member, and the third member between the first roller and the second roller.

[0016] (6) Preferably, the above bonding portion may bond the first member, the second member, and the third member in a state where they are overlapped in the order of the first member, the third member, and the second member between the first roller and the second roller.

[0017] (7) Preferably, the angle formed by the direction in which the first member is conveyed toward the bonding portion and the direction in which the member formed by bonding the first member, the second member, and the third member is conveyed from the bonding portion may be an obtuse angle.

[0018] (8) Preferably, the angle formed by the direction in which the second member and the third member are conveyed toward the bonding portion and the direction in which the member formed by bonding the first member, the second member, and the third member is conveyed from the bonding portion may be an obtuse angle.

[0019] (9) Preferably, the acute angle formed by the horizontal direction and the direction of the line segment connecting the center of the first roller and the center of the second roller may be 40° or more and 75° or less.

[0020] Preferably, the laminating device may further include a first guiding portion that abuts against the joint surfaces where the second member and the third member are joined to the first member, and guides the second member and the third member toward the joint portion.

[0021] Preferably, a space for floating the rear end of the second member that has passed through the first guiding portion may be located between the first guiding portion and the joint portion.

[0022] Preferably, the laminating device may further include a second guiding portion that abuts against the joint surface of the first member and guides the first member toward the joint portion.

[0023] Preferably, the laminating device may further include a cutting portion on the downstream side of the joint portion that cuts the member formed by laminating the first member, the second member, and the third member, and the cutting portion cuts the portion other than the portion where the first member, the second member, and the third member are all overlapped.

[0024] Preferably, the second member and the third member may be transparent films, and the laminating device further includes a recording portion that records an image on the third member.

[0025] Preferably, the laminating device may further include a driving portion that drives the second roller, and the first roller is a driven roller that does not directly receive power from the driving portion.

[0026] Preferably, the laminating device may further include a driving portion that drives the first roller and the second roller.

[0027] The laminating device of the present invention includes: a joint portion having rollers for overlapping and joining a plurality of members; a conveying portion including a first conveying portion that conveys a first member to the joint portion and a second conveying portion that conveys a second member and a third member to the joint portion; and a control portion. The control portion performs the following first joint operation: conveys the first member to the joint portion through the first conveying portion, conveys the second member to the joint portion through the second conveying portion, and joins the first member and the second member. After the first joint operation, the control portion conveys the third member through the second conveying portion in such a manner that the front end of the third member approaches the rear end of the second member while holding the first member and the second member by the joint portion. After conveying the third member, the control portion performs a second joint operation of joining the first member and the third member.

[0028] According to the above lamination device, when the first member has an adhesive layer on the bonding surface and the second member and the third member are bonded to the bonding surface of the first member, the first member and the second member are bonded. While the first member and the second member are held by the bonding portion, the front end of the third member is brought close to the rear end of the second member, and the first member and the third member are bonded. As a result, the gap between the second member and the third member is reduced, and contact between the adhesive layer of the first member and the components in the bonding portion can be reduced. In addition, in this structure, the first member, the second member, and the third member do not necessarily overlap.

[0029] (18) Preferably, in the first bonding operation, the control unit may stop the operation of the bonding portion after bonding the first part including the front end of the first member and the second member. In the second bonding operation, the control unit performs the bonding of the first member and the second part, which is the part obtained by removing the first part from the second member, and the bonding of the first member and the third member in a continuous operation.

[0030] Advantages of the Invention

[0031] According to the present invention, contact between the adhesive layer of the bonded members and the components in the bonding portion can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Hereinafter, the laminating device 1 according to the embodiment of the present invention will be described. In addition, the embodiments described below are merely examples of the present invention, and of course, the embodiments of the present invention can be appropriately changed without changing the gist of the present invention. In the following description, the forward movement from the starting point to the ending point of the arrow is expressed as "toward", and the movement back and forth on the line connecting the starting point and the ending point of the arrow is expressed as "direction". In addition, taking the state ( Figure 1 of (A)) in which the laminating device 1 is set to a usable state as a reference, the up-down direction 7 is defined, 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 surface, and the left-right direction 9 is defined when observing the laminating device 1 from the front. The up-down direction 7, the front-rear direction 8, and the left-right direction 9 are orthogonal to each other.

[0042] [Outline of Laminating Device 1]

[0043] As Figure 1 shown in (A), the laminating device 1 of the present embodiment has a rectangular parallelepiped-shaped housing 11. The operation unit 12 and the display unit 13 are located on the front surface of the housing 11. On the front surface of the housing 11, the discharge port 14 is located below the operation unit 12 and the display unit 13. The laminating device 1 laminates two types of members to produce a laminated finished product 100.

[0044] The strip-shaped first member 101 and the third member 103 are supplied to the laminating device 1. As Figure 2 shown, the first member 101 is wound around a cylindrical core material 113 to form a first reel 111. The third member 103 is wound around a cylindrical core material 114 to form a second reel 112. The first reel 111 and the second reel 112 are respectively installed on the first holder 17 and the second holder 18 of the laminating device 1.

[0045] The third member 103 is, for example, a transparent film. As Figure 1As shown in (B) of, the first member 101 is a member having an adhesive layer on at least one surface. For example, the first member 101 is a backing paper having a first adhesive layer 104 on one surface of the tape layer 105 (the surface on the side of the third member 103 in the laminated finished product 100) and a second adhesive layer 106 on the other surface of the tape layer 105. A release film 107 is provided on the opposite side of the tape layer 105 across the second adhesive layer 106.

[0046] In addition, the materials of the first member 101 and the third member 103 are arbitrary. For example, the first member 101 may also be a member made of resin such as PET or PVC (vinyl chloride), synthetic paper such as Upo paper (registered trademark), a member made of metal, etc. The first member 101 may be transparent or opaque. The first member 101 may also be a member having an adhesive layer on one surface and not having an adhesive layer on the other surface. In addition, the first member 101 may also be a member having the first adhesive layer 104 formed on one surface after being pulled out from the first reel 111.

[0047] In Figure 2 the bonding surface 108 is the surface of the first member 101 that has the first adhesive layer 104. The bonding surface 109 is the surface of the third member 103 that is on the side of the bonding surface 108 of the first member 101. The bonding surface 109 is also the recording surface for recording an image.

[0048] The laminating device 1 makes the first member 101 and the third member 103 adhere by bringing the bonding surface 108 of the first member 101 into close contact with the bonding surface 109 of the third member 103. The laminating device 1 cuts the adhered members into a specified size. Thus, the Figure 1 laminated finished product 100 shown in (B) of is manufactured. The manufactured laminated finished product 100 is discharged from the discharge port 14.

[0049] As Figure 2 shown, the laminating device 1 includes a conveying unit 20, a recording unit 30, a cutting unit 40, a bonding unit 50, a first guiding member 61, a second guiding member 62, and a second cutting unit 70 inside the housing 11. In addition, the laminating device 1 includes a control unit 90 and various motors (refer to Figure 3 ). Guiding members (not shown) for supporting the first member 101 and the third member 103 are provided at necessary positions inside the housing 11. Thus, a conveying path 15 from the first holder 17 to the second cutting unit 70 via the bonding unit 50 and a conveying path 16 from the second holder 18 to the second cutting unit 70 via the recording unit 30, the cutting unit 40, and the bonding unit 50 are formed.

[0050] [First holder 17 and second holder 18]

[0051] The first cage 17 and the second cage 18 are members that can rotate about an axis extending in the left - right direction 9. The thickness of the first cage 17 is equal to the inner diameter of the core 113 of the first reel 111. The thickness of the second cage 18 is equal to the inner diameter of the core 114 of the second reel 112. The first cage 17 and the second cage 18 are fixed to the housing 11 or to a member fixed to the housing 11.

[0052] The first cage 17 and the second cage 18 are located at separate positions within the housing 11. In Figure 2 the structure shown, the first cage 17 is located above the housing 11 in the up - down direction 7 and in front of the housing 11 in the front - rear direction 8. The second cage 18 is located below the center of the housing 11 in the up - down direction 7 and behind the housing 11 in the front - rear direction 8. It should be noted that the positions of the first cage 17 and the second cage 18 within the housing 11 are arbitrary.

[0053] Before the lamination device 1 operates, the first reel 111 is mounted on the first cage 17, and the second reel 112 is mounted on the second cage 18. The first cage 17 rotatably supports the first reel 111. The second cage 18 rotatably supports the second reel 112. The first member 101 is pulled out from the first reel 111 supported by the first cage 17. The third member 103 is pulled out from the second reel 112 supported by the second cage 18.

[0054] The second cage 18 receives a driving force from the cage electric motor 81 (refer to Figure 3 ) and rotates in a specified direction (counter - clockwise direction in Figure 2 ). As a result, the third member 103 pulled out from the second reel 112 is wound back onto the second reel 112.

[0055] [Conveyor section 20]

[0056] The conveyor section 20 includes a first pulling roller 21, a second pulling roller 22, a third pulling roller 23, and a fourth pulling roller 24. In addition, the bonding section 50 also functions as the conveyor section 20. The first pulling roller 21 and the second pulling roller 22 form a roller pair, and pull out the first member 101 from the first reel 111. The third pulling roller 23 and the fourth pulling roller 24 form another roller pair, and pull out the third member 103 from the second reel 112.

[0057] The first pulling roller 21 and the second pulling roller 22 are located near the first reel 111. In Figure 2In the structure shown, the first pulling roller 21 and the second pulling roller 22 are located behind the first reel 111 in the front-rear direction 8. The first pulling roller 21 is located above the second pulling roller 22 in the up-down direction 7 and behind the second pulling roller 22 in the front-rear direction 8. The first member 101 pulled out from the first reel 111 passes between the first pulling roller 21 and the second pulling roller 22. At this time, the contact surface 108 of the first pulling roller 21 abuts against the first member 101, and the surface (back surface) on the opposite side of the contact surface 108 of the first member 101 abuts against the second pulling roller 22. The first pulling roller 21 is, for example, a toothed roller. Alternatively, the portion of the first pulling roller 21 that abuts against the first member 101 may be processed so as to be easily separated from the first adhesive layer 104 of the first member 101.

[0058] The third pulling roller 23 and the fourth pulling roller 24 are located near the second reel 112. In Figure 2 the structure shown, the third pulling roller 23 and the fourth pulling roller 24 are located in front of the second reel 112 in the front-rear direction 8. The third pulling roller 23 is located directly above the fourth pulling roller 24 in the up-down direction 7. The third member 103 pulled out from the second reel 112 passes between the third pulling roller 23 and the fourth pulling roller 24. At this time, the contact surface 109 of the third pulling roller 23 abuts against the third member 103, and the surface (back surface) on the opposite side of the contact surface 109 of the third member 103 abuts against the fourth pulling roller 24.

[0059] The second pulling roller 22 and the fourth pulling roller 24 receive driving force from a conveying motor 82 (see Figure 3 ), and rotate about an axis extending in the left-right direction 9. The first pulling roller 21 and the third pulling roller 23 rotate about an axis extending in the left-right direction 9 respectively as the second pulling roller 22 and the fourth pulling roller 24 rotate. The second fitting roller 52 (described later) included in the fitting portion 50 receives driving force from a fitting motor 85 (see Figure 3 ), and rotates about an axis extending in the left-right direction 9. The first fitting roller 51 (described later) rotates about an axis extending in the left-right direction 9 as the second fitting roller 52 rotates. Thus, the first member 101 is conveyed along the conveying path 15, and the third member 103 is conveyed along the conveying path 16. In this way, the conveying unit 20 conveys a plurality of members to the fitting portion 50.

[0060] The first pulling roller 21, the second pulling roller 22, and the fitting portion 50 are an example of a first conveying unit that conveys the first member 101 to the fitting portion 50. The third pulling roller 23, the fourth pulling roller 24, and the fitting portion 50 are an example of a second conveying unit that conveys a second member 102 (described later) and the third member 103 to the fitting portion 50.

[0061] [Recording unit 30]

[0062] The recording unit 30 is located on the downstream side of the second reel 112 with respect to the conveyance path 16. The recording unit 30 is located above the conveyance path 16 in the vertical direction 7 and is located between the second reel 112 and the cutting unit 40 in the front-rear direction 8. The recording unit 30 includes a carriage 31 and a recording head 32. Two guide rails 36, 37 that extend in the left-right direction 9 and have both ends fixed to the housing 11 or fixed to members fixed to the housing 11 are located inside the housing 11. The carriage 31 is placed on the guide rails 36, 37. The carriage 31 receives driving force from a CR motor 83 (refer to Figure 3 ) and moves in the left-right direction 9.

[0063] The recording head 32 is mounted on the carriage 31. A plurality of nozzles 33 are formed on the lower surface of the recording head 32. As the carriage 31 moves, the recording head 32 moves in the left-right direction 9. The impression plate 34 is located below the movement range of the carriage 31. While moving in the left-right direction 9, the recording head 32 ejects liquid ink from the nozzles 33. Thereby, an image is recorded on the bonding surface 109 that also serves as the recording surface of the third member 103 conveyed on the impression plate 34. In this way, the recording unit 30 records an image on the third member 103 pulled out from the second reel 112.

[0064] A medium sensor 35 is mounted on the carriage 31. The medium sensor 35 includes a light-emitting element and a light-receiving element (both not shown). The light-emitting element emits light downward from the lower surface of the recording head 32. The light-receiving element receives the light reflected by the impression plate 34 or the third member 103 conveyed on the impression plate 34 after being emitted from the light-emitting element. The amount of light received by the light-receiving element varies depending on whether the third member 103 is present on the impression plate 34. Therefore, the ends of the second member 102 and the third member 103 can be detected by the medium sensor 35. The medium sensor 35 is an example of a first sensor unit and a second sensor unit.

[0065] [Cutting Unit 40]

[0066] The cutting unit 40 is located on the downstream side of the recording unit 30 with respect to the conveyance path 16. The cutting unit 40 is located above the conveyance path 16 in the vertical direction 7 and is located between the recording unit 30 and the bonding unit 50 in the front-rear direction 8. The cutting unit 40 includes a cutter carriage 41 and a cutter 42. Two guide rails 43, 44 having the same structure as the guide rails 36, 37 are located inside the housing 11. The cutter carriage 41 is placed on the guide rails 43, 44. The cutter carriage 41 receives driving force from a cutting motor 84 (refer to Figure 3 ) and moves in the left-right direction 9.

[0067] A cutter 42 is provided below the cutter carriage 41. As the cutter carriage 41 moves, the cutter 42 moves in the left - right direction 9. For example, when the cutter carriage 41 moves in a specified orientation (e.g., toward the right) along the left - right direction 9, the cutter 42 cuts the third member 103 conveyed to the cutting portion 40. In this way, the cutting portion 40 cuts the third member 103 on which the image has been recorded by the recording portion 30.

[0068] [Bonding portion 50]

[0069] The bonding portion 50 is located at a position downstream of the cutting portion 40 with respect to the conveying path 16. In the front - rear direction 8, the bonding portion 50 is located between the cutting portion 40 and the second cutting portion 70. The bonding portion 50 includes a first bonding roller 51 and a second bonding roller 52. The first bonding roller 51 is spaced apart by an interval corresponding to the thickness of the laminated finished product 100, is located above the second bonding roller 52 in the up - down direction 7, and is located in front of the second bonding roller 52 in the front - rear direction 8.

[0070] The first member 101 pulled out from the first reel 111 enters between the first bonding roller 51 and the second bonding roller 52. At this time, the bonding surface 108 of the first member 101 faces backward and downward. The third member 103 that has passed through the recording portion 30 and the cutting portion 40 enters below the first member 101 between the first bonding roller 51 and the second bonding roller 52. At this time, the bonding surface 109 of the third member 103 faces forward and upward.

[0071] As described above, the second bonding roller 52 receives a driving force from a bonding motor 85 (see Figure 3 ), and rotates about an axis extending in the left - right direction 9. The first bonding roller 51 is a driven roller, and rotates about an axis extending in the left - right direction 9 as the second bonding roller 52 rotates. The first bonding roller 51 and the second bonding roller 52 press the bonding surface 108 of the first member 101 against the bonding surface 109 of the third member 103, thereby bonding the first member 101 and the third member 103.

[0072] The second bonding roller 52 is driven by the bonding motor 85. The second bonding roller 52 is an example of the first roller. The first bonding roller 51 is a driven roller that does not directly receive power from the bonding motor 85. The first bonding roller 51 is an example of the second roller. The details of the bonding portion 50 will be described later.

[0073] [First guide member 61 and second guide member 62]

[0074] The first guiding member 61 is located in front of the bonding portion 50 along the conveying path 16. The first guiding member 61 is located at substantially the same position as the bonding portion 50 in the vertical direction 7 and is located behind the bonding portion 50 in the front-rear direction 8. The first guiding member 61 abuts against the bonding surface 109 of the third member 103 that has passed through the recording portion 30 and the cutting portion 40, and guides the second member 102 and the third member 103 toward the bonding portion 50. The first guiding member 61 is, for example, a toothed roller. The first guiding member 61 is an example of the first guiding portion.

[0075] The second guiding member 62 is located in front of the bonding portion 50 along the conveying path 15. The second guiding member 62 is located above the bonding portion 50 in the vertical direction 7 and is located at substantially the same position as the bonding portion 50 in the front-rear direction 8. The second guiding member 62 abuts against the bonding surface 108 of the first member 101 pulled out from the first reel 111, and guides the first member 101 toward the bonding portion 50. The second guiding member 62 is, for example, a toothed roller. The second guiding member 62 is an example of the second guiding portion.

[0076] [Second cutting portion 70]

[0077] The second cutting portion 70 is located on the downstream side of the bonding portion 50 with respect to the conveying paths 15 and 16. The second cutting portion 70 is located below the bonding portion 50 in the vertical direction 7 and is located in front of the bonding portion 50 in the front-rear direction 8. The second cutting portion 70 cuts the member formed by bonding the first member 101, the second member 102, and the third member 103. The second cutting portion 70 has an arbitrary structure capable of cutting the bonded member. The second cutting portion 70 may have a structure including a cutter carriage that moves in the left-right direction 9 and a cutter, similar to the cutting portion 40, or may have a structure including a moving blade that moves in a direction orthogonal to the member to be cut and a fixed blade opposed to the moving blade. The second cutting portion 70 is an example of the cutting portion.

[0078] [First discharge roller 25 and second discharge roller 26]

[0079] The first discharge roller 25 and the second discharge roller 26 form a pair of discharge rollers. The first discharge roller 25 and the second discharge roller 26 are located below the second cutting portion 70 in the vertical direction 7 and are located in front of the second cutting portion 70 in the front-rear direction 8. The first discharge roller 25 is spaced apart by an interval corresponding to the thickness of the laminated product 100, is located above the second discharge roller 26 in the vertical direction 7, and is located in front of the second discharge roller 26 in the front-rear direction 8.

[0080] The second discharge roller 26 receives driving force from the conveyance motor 82 and rotates about an axis extending in the left-right direction 9. The first discharge roller 25 rotates about an axis extending in the left-right direction 9 as the second discharge roller 26 rotates. The member that has passed through the second cutting unit 70 passes between the first discharge roller 25 and the second discharge roller 26 and is discharged from the discharge port 14.

[0081] [Control Unit 90 and Its Peripheral Parts]

[0082] As Figure 3 shown, the control unit 90 includes a CPU 91, a ROM 92, a RAM 93, and an EEPROM 94. Programs and the like for controlling various operations of the laminating apparatus 1 are stored in the ROM 92. Various data used when executing the above programs are stored in the EEPROM 94. The RAM 93 is used as a storage area for temporarily recording various data used when the CPU 91 executes the above programs or as an expansion area for data and programs. When the power of the laminating apparatus 1 is turned 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. Thereby, the control unit 90 performs various controls.

[0083] The operation unit 12 and the display unit 13 are connected to the ASIC 95. The operation unit 12 detects the 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 signal output from the operation unit 12. The display unit 13 displays information related to the operation of the laminating apparatus 1 on the screen based on an instruction from the control unit 90.

[0084] A recording head 32 is connected to the ASIC 95. The controller 90 outputs a signal corresponding to the image data to the recording head 32 via the ASIC 95. The recording head 32 ejects liquid ink from a plurality of nozzles 33 provided in the recording head 32 according to the signal output from the control unit 90.

[0085] A medium sensor 35 is connected to the ASIC 95. The medium sensor 35 outputs a signal corresponding to the amount of light received by the light receiving element. The control unit 90 detects the ends of the second member 102 and the third member 103 conveyed along the conveyance path 16 based on the signal output from the medium sensor 35.

[0086] A cage motor 81, a conveyance motor 82, a CR motor 83, a cutting motor 84, and a laminating motor 85 are connected to the ASIC 95. A drive circuit for controlling these motors is incorporated in the ASIC 95. The control unit 90 outputs drive signals for rotating the respective motors to the drive circuits corresponding to the respective motors. The drive circuits output drive currents corresponding to the drive signals output from the control unit 90 to the corresponding motors. Thereby, the corresponding motors rotate.

[0087] The control unit 90 controls the cage motor 81 to rotate the second cage 18, and wind the third member 103 pulled out from the second reel 112 back to the second reel 112. The control unit 90 controls the conveyance motor 82 to drive the second pulling roller 22, the fourth pulling roller 24, and the second discharging roller 26. The control unit 90 controls the CR motor 83 to move the carriage 31. The control unit 90 controls the cutting motor 84 to move the cutter carriage 41 and the second cutting unit 70. The control unit 90 controls the bonding motor 85 to rotate the second bonding roller 52. The bonding motor 85 is an example of a driving unit.

[0088] [Processing of Control Unit 90]

[0089] Refer to Figure 4 to describe the processing of the control unit 90. Figure 4 The processing shown is executed by the control unit 90 by executing a program stored in the RAM 93. The cutting unit 40 cuts the third member 103 into two parts along the left - right direction 9. Hereinafter, the part located on the downstream side (the front side in the front - rear direction 8) of the two parts obtained by the operation of the cutting unit 40 is referred to as the "second member". In the drawings, the second member is labeled with reference numeral 102 (refer to Figure 5 (A) etc. of Figure 4 . Before executing the processing shown in

[0090] , the front end of the second member 102 is on the downstream side of the bonding unit 50 in the conveyance path 16, and the front end 123 of the third member 103 is on the upstream side of the recording unit 30 in the conveyance path 16.

[0090] At the beginning of the processing shown in Figure 4 , the control unit 90 bonds the first member 101 to a part (hereinafter, referred to as the "first part") including the front end of the second member 102 through the bonding unit 50 (S11). In S11, the control unit 90 drives the bonding motor 85 to rotate the second bonding roller 52, thereby bonding the first member 101 to the first part of the second member 102. Additionally, at this time, the first bonding roller 51 rotates as the second bonding roller 52 rotates.

[0091] In S11, when a predetermined conveyance amount is conveyed from the position where the rear end 122 of the second member 102 is detected by the medium sensor 35, the control unit 90 stops driving the bonding motor 85. Thereby, the control unit 90 stops the rear end 122 of the second member 102 at a position where a predetermined conveyance amount has been conveyed from the position where the rear end 122 of the second member 102 is detected by the medium sensor 35.

[0092] Next, the control unit 90 conveys the third member 103 to the recording position (S12). In S12, the controller 90 drives the conveyance motor 82 to rotate the fourth pulling roller 24, thereby conveying the third member 103 pulled out from the second reel 112 to the recording position on the impression plate 34. Additionally, at this time, the second pulling roller 22 is not driven, and the third pulling roller 23 rotates as the fourth pulling roller 24 rotates.

[0093] Next, the control unit 90 records an image on the first member 101 using the recording unit 30 (S13). In S13, the control unit 90 drives the CR motor 83 to move the carriage 31 in the left-right direction 9, and supplies data corresponding to the image to be recorded to the recording head 32, thereby recording the image on the third member 103 located on the impression plate 34. When the image recording for one stroke amount is completed, the control unit 90 drives the conveyance motor 82 to rotate the third pulling roller 23, thereby conveying the third member 103 along the conveyance path 15 to the position where the next image is to be recorded. At this time, the second pulling roller 22 is not driven, and the third pulling roller 23 rotates as the fourth pulling roller 24 rotates. When an image of one quantity is recorded on the third member 103, the control unit 90 proceeds to S14.

[0094] Next, the control unit 90 conveys the third member 103 to the bonding position (S14). In S14, the control unit 90 drives the conveyance motor 82 to rotate the fourth pulling roller 24, thereby conveying the third member 103 pulled out from the second reel 112 to the bonding position of the bonding unit 50. At this time, the first member 101 and the second member 102 are located between the first bonding roller 51 and the second bonding roller 52. In S14, with the first member 101 and the second member 102 held by the bonding unit 50, the control unit 90 uses the fourth pulling roller 24 to bring the front end 123 of the third member 103 close to the rear end 122 of the second member 102 (refer to Figure 5 (A) of

[0095] Next, the control unit 90 cuts the third member 103 using the cutting unit 40 (S15). In S15, the control unit 90 drives the cutting motor 84 to move the cutter carriage 41 in the left-right direction 9, thereby cutting the third member 103 on which the image has been recorded by the recording unit 30 in the left-right direction 9. Here, the cutting of the third member 103 does not necessarily have to be performed at this moment. When there is still an image to be recorded on the third member 103, S15 is executed after S17.

[0096] Next, the control unit 90 causes the first member 101 to be joined to the portion of the second member 102 from which the first portion has been removed (hereinafter referred to as the "second portion") by the joining unit 50 (S16). In S16, the control unit 90 drives the joining motor 85 to rotate the second joining roller 52, thereby joining the first member 101 to the second portion of the second member 102. In S16, the control unit 90 starts the operation of the joining motor 85 after the third member 103 has been conveyed a predetermined conveyance amount from the position where the front end 123 of the third member 103 is detected by the medium sensor 35. Also, at this time, the first joining roller 51 rotates as the second joining roller 52 rotates.

[0097] Next, the control unit 90 causes the first member 101 to be joined to the portion of the third member 103 including the front end 123 by the joining unit 50 (S17). In S17, the control unit 90 drives the joining motor 85 to rotate the second joining roller 52, thereby joining the first member 101 to the portion of the third member 103 including the front end 123. Also, at this time, the first joining roller 51 rotates as the second joining roller 52 rotates. The control unit 90 performs S16 and S17 in a continuous operation.

[0098] Next, the control unit 90 cuts the member joined by the joining unit 50 by the second cutting unit 70 (S18). In S18, the control unit 90 drives the cutting motor 84 to cause the second cutting unit 70 to cut the member joined by the joining unit 50.

[0099] Next, the controller 90 winds the third member 103 back onto the second reel 112 (S19). In S19, the control unit 90 drives the cage motor 81 to rotate the second cage 18, thereby winding the member on the upstream side of the third member 103 cut by the cutting unit 40 back onto the second reel 112. At this time, the control unit 90 winds the member on the upstream side of the third member 103 back to a position upstream of the recording unit 30 (in Figure 2 this case, to the left of the recording unit 30). The control unit 90 detects the front end 123 of the third member 103 based on the signal output from the medium sensor 35. After detecting the front end 123 of the third member 103 and winding the third member 103 back by a predetermined amount, the control unit 90 stops winding the third member 103.

[0100] [Details of the joining unit 50]

[0101] When the control unit 90 executes Figure 4Before the processing shown, the first member 101 and the second member 102 are located between the first laminating roller 51 and the second laminating roller 52. At the moment when the control unit 90 executes S11, the first part of the first member 101 and the second member 102 including the rear end 122 is laminated through the lamination part 50. At this time, the lamination surface 108 of the first member 101 faces backward and downward. In addition, the control unit 90 executes S14, whereby the third member 103 is conveyed in such a manner that the front end 123 of the third member 103 approaches the rear end 122 of the second member 102. At this time, the lamination surface 109 of the third member 103 faces forward and upward.

[0102] The third member 103 has a prescribed rigidity. Therefore, as shown in (A) of Figure 5 , the rear end 122 of the second member 102 separates from the outer peripheral surface of the second laminating roller 52 and floats from the outer peripheral surface of the second laminating roller. A space 63 for floating the rear end 122 of the second member 102 that has passed through the first guide member 61 is located on the side where the first member 101 and the third member 103 enter in the lamination part 50 (in the upper left part of the first laminating roller 51 and the second laminating roller 52 in (A) of Figure 5 ).

[0103] When the control unit 90 executes S14, the third member 103 is conveyed forward. At this time, since the rear end 122 of the second member 102 is in a floating state within the space 63, the third member 103 enters below the second member 102. The first member 101 and the third member 103 are pressed against and laminated when passing between the first laminating roller 51 and the second laminating roller 52. The lamination part 50 laminates the first member 101 and the third member 103 by pressing the lamination surface 108 of the first member 101 against the lamination surface 109 of the third member 103.

[0104] In this way, the control unit 90 causes the lamination part 50 to laminate in a state where a part of the first member 101, a part of the second member 102 including the rear end 122, and a part of the third member 103 including the front end 123 overlap (refer to (B) of Figure 5 ). The lamination part 50 laminates the first member 101, the second member 102, and the third member 103 in a state where they overlap in the order of the first member 101, the second member 102, and the third member 103.

[0105] Refer to Figure 6 to explain the angles in the lamination part 50. As shown in Figure 6As shown in (A) of FIG. , the direction in which the first member 101 is conveyed toward the bonding portion 50 is referred to as the "first direction D1". The directions in which the second member 102 and the third member 103 are conveyed toward the bonding portion 50 are referred to as the "second direction D2". The direction in which the member formed by bonding the first member 101, the second member 102, and the third member 103 is conveyed from the bonding portion 50 is referred to as the "third direction D3". The direction of the line segment connecting the center of the first bonding roller 51 and the center of the second bonding roller 52 is referred to as the "fourth direction D4".

[0106] In the laminating apparatus 1, the angle θ1 formed by the first direction D1 and the third direction D3 is preferably an obtuse angle. The angle θ1 is preferably 135°, for example. The angle θ2 formed by the second direction D2 and the third direction D3 is preferably an obtuse angle (see Figure 6 in (B) of FIG. ). The acute angle θ3 formed by the horizontal direction DH and the fourth direction D4 is preferably 40° or more and 75° or less (see Figure 6 in (C) of FIG. ). If the acute angle θ3 is too small, the third member 103 cannot smoothly enter below the second member 102. On the other hand, if the acute angle θ is too large, the third member 103 cannot smoothly enter between the second member 102 and the second bonding roller 52. Therefore, the acute angle θ3 is preferably 40° or more and 75° or less, and preferably 65°, for example.

[0107] [Details of the second cutting portion 70]

[0108] As described above, the second cutting portion 70 cuts the member formed by bonding a plurality of members by the bonding portion 50. The bonding portion 50 performs bonding in a state where a part of the first member 101, the second member 102 including the rear end 122, and a part of the third member 103 including the front end 123 overlap. When cutting the member formed by bonding the first member 101, the second member 102, and the third member 103, the second cutting portion 70 cuts the portion other than the portion where the first member 101, the second member 102, and the third member 103 all overlap.

[0109] The portion other than the portion where the first member 101, the second member 102, and the third member 103 all overlap specifically refers to the portion where the first member 101 and the second member 102 overlap, or the portion where the first member 101 and the third member 103 overlap. In the Figure 7 example shown in FIG. , the second cutting portion 70 cuts the member formed by bonding the first member 101, the second member 102, and the third member 103 at the portion X where the first member 101 and the third member 103 overlap and the second member 102 does not overlap.

[0110] In the above description, the conveyance motor 82 drives the second pulling roller 22 and the fourth pulling roller 24, and the bonding motor 85 drives the second bonding roller 52. However, the conveyance motor 82 may also drive at least one of the first pulling roller 21 and the second pulling roller 22, and drive at least one of the third pulling roller 23 and the fourth pulling roller 24. For example, the conveyance motor 82 may drive both the first pulling roller 21 and the second pulling roller 22, or may drive the first pulling roller 21 without driving the second pulling roller 22. Further, the bonding motor 85 may also drive at least one of the first bonding roller 51 and the second bonding roller 52.

[0111] When the bonding motor 85 drives both the first bonding roller 51 and the second bonding roller 52, if one bonding roller is directly connected to the other bonding roller, the clamping load may sometimes be released. Therefore, it is preferable to connect the two bonding rollers to the bonding motor 85 respectively. However, one bonding roller may also be directly connected to the other bonding roller.

[0112] [Effects of the Embodiment]

[0113] As described above, the laminating apparatus 1 of the present embodiment includes a bonding portion 50 that overlaps and bonds a plurality of members, a conveyance portion 20 that conveys the plurality of members to the bonding portion 50, and a control portion 90. The control portion 90 causes the bonding portion 50 to perform bonding in a state where a part of the first member 101 and the second member 102 including the rear end 122 overlaps with a part of the third member 103 including the front end 123.

[0114] According to the laminating apparatus 1 of the present embodiment, when the first member 101 has the first adhesive layer 104 on the bonding surface 108, and when the second member 102 and the third member 103 are bonded to the bonding surface 108 of the first member 101, by performing bonding such that a part of the second member 102 including the rear end 122 overlaps with a part of the third member 103 including the front end located upstream of the second member 102 in the conveyance direction, no gap is generated between the second member 102 and the third member 103, and contact between the first adhesive layer 104 of the first member 101 and the components in the bonding portion 50 can be reduced.

[0115] In a laminating apparatus having a bonding portion for bonding a plurality of members, when the front end of each member enters the bonding portion, the posture of the front end may sometimes be unstable. In this case, the bonding of the members may sometimes not be correctly performed, resulting in a deviation in the bonding position, or an increase in the occurrence of jamming of the members. According to the laminating apparatus 1 of the present embodiment, the contact between the adhesive layer of the member and the components in the bonding portion can be reduced, the bonding accuracy can be improved, and the occurrence of jamming of the members can be reduced.

[0116] In addition, in S11, the control unit 90 of the laminating device 1 stops the rear end 122 of the second member 102 at a position where a predetermined conveyance amount has been conveyed from the position where the rear end 122 of the second member 102 is detected by the medium sensor 35. Therefore, based on the position where the rear end 122 of the second member 102 is detected by the medium sensor 35, the second member 102 is stopped at a position suitable for lamination, so that the overlapping state can be reproduced with high accuracy. In addition, since the overlapping distance can be reduced, waste of materials can be reduced.

[0117] In addition, in S16, after the control unit 90 of the laminating device 1 conveys the third member 103 by a predetermined conveyance amount from the position where the front end 123 of the third member 103 is detected by the medium sensor 35, the control unit 90 starts the operation of the laminating unit 50. Therefore, based on the position where the front end 123 of the third member 103 is detected by the medium sensor 35 and starting the operation of the laminating unit 50 after the third member 103 has been conveyed by a predetermined conveyance amount, the state in which a part of the second member 102 including the rear end 122 overlaps with a part of the third member 103 including the front end 123 can be reproduced with high accuracy. In addition, since the overlapping distance can be reduced, waste of materials can be reduced.

[0118] In addition, the laminating unit 50 includes a pair of rollers including a first laminating roller 51 and a second laminating roller 52. Therefore, by the two rollers, a part of the first member 101, the second member 102 including the rear end 122, and a part of the third member 103 including the front end 123 can be laminated. In addition, the laminating unit 50 laminates the first member 101, the second member 102, and the third member 103 in a state where they overlap in the order of the first member 101, the second member 102, and the third member 103 between the first laminating roller 51 and the second laminating roller 52. Therefore, in the laminating unit 50, the three members 101 to 103 are laminated in a state where they overlap in the order of the first member 101, the second member 102, and the third member 103. Thus, the front end 123 of the third member 103 supplied from the upstream can start lamination by contacting a part of the second member 102 including the rear end 122 without directly contacting the lamination surface 108 having the first adhesive layer 104 of the first member 101, so that the start of the lamination operation is stable.

[0119] In addition, the angle θ1 formed by the direction D1 (the direction in which the first member 101 is conveyed toward the laminating unit 50) and the direction D2 (the direction in which the second member 102 and the third member 103 are conveyed toward the laminating unit 50) is an obtuse angle ( Figure 7(B)). Therefore, it is difficult to apply a force in the direction of separating the rollers to the pair of rollers (the first bonding roller 51 and the second bonding roller 52) included in the bonding portion 50. In addition, the angle θ2 formed by the direction D2 and the direction D3 (the direction in which the member formed by bonding the first member 101, the second member 102, and the third member 103 is conveyed from the bonding portion 50) is an obtuse angle ( Figure 7 (B)). Therefore, a part of the third member 103 including the front end 123 easily enters under a part of the second member 102 including the rear end 122.

[0120] In addition, the acute angle θ3 formed by the horizontal direction DH and the fourth direction D4 (the direction of the line segment connecting the center of the first bonding roller 51 and the center of the second bonding roller 52) is 40° or more and 75° or less. Therefore, it is difficult to apply a force in the direction of separating the rollers to the pair of rollers included in the bonding portion 50, and a part of the third member 103 including the front end 123 easily enters under a part of the second member 102 including the rear end 122.

[0121] In addition, the laminating device 1 includes a first guiding member 61 that abuts against the bonding surface 109 where the second member 102 and the third member 103 are bonded to the first member 101 and guides the second member 102 and the third member 103 toward the bonding portion 50. Therefore, the second member 102 and the third member 103 can be guided toward the bonding portion 50 by the first guiding member 61, and thus the positions of the front ends of the second member 102 and the third member 103 conveyed to the bonding portion 50 are stable.

[0122] In addition, a space 63 for floating the rear end 122 of the second member 102 that has passed through the first guiding member 61 is located between the first guiding member 61 and the bonding portion 50. Therefore, the second member 102 that has passed through the first guiding member 61 floats, and thus a part of the third member 103 including the front end 123 easily enters below a part of the second member 102 including the rear end 122.

[0123] In addition, the laminating device 1 includes a second guiding member 62 that abuts against the bonding surface 108 of the first member 101 and guides the first member 101 toward the bonding portion 50. Therefore, the first member 101 can be guided toward the bonding portion 50 by the second guiding member 62, and thus the position of the front end of the first member 101 conveyed to the bonding portion 50 is stable.

[0124] In addition, the laminating apparatus 1 includes a second cutting unit 70 which is located on the downstream side of the bonding unit 50 and cuts the member formed by bonding the first member 101, the second member 102, and the third member 103. The second cutting unit 70 cuts the portion other than the portion where the first member 101, the second member 102, and the third member 103 all overlap (specifically, the portion where the first member 101 and the second member 102 overlap, or the portion where the first member 101 and the third member 103 overlap). Therefore, deterioration of the cutting blade included in the second cutting unit 70 can be suppressed. In addition, since the thickness of the portion to be cut is thin, cutting failure can be reduced and the cut cross section can be made into a neat state. Furthermore, cutting accuracy can be improved. However, the second cutting unit 70 may also cut the portion where the first member 101, the second member 102, and the third member 103 all overlap.

[0125] In addition, the second member 102 and the third member 103 are transparent films, and the laminating apparatus 1 includes a recording unit 30 that records an image on the third member 103. Therefore, an image can be recorded on the third member 103 among the three bonded members 101 to 103. In addition, since the transparent film is thin, the thickness of the overlapping portion can be suppressed by overlapping the transparent films.

[0126] In addition, the laminating apparatus 1 includes a bonding motor 85 that drives the second bonding roller 52, and the first bonding roller 51 is a driven roller that does not directly receive power from the bonding motor 85. Therefore, the second bonding roller 52 can be driven by the bonding motor 85, and the first bonding roller 51 can be rotated as the second bonding roller 52 rotates. In addition, the laminating apparatus 1 may include a bonding motor 85 that drives the first bonding roller 51 and the second bonding roller 52. Thereby, the first bonding roller 51 and the second bonding roller 52 can be driven by the same bonding motor 85.

[0127] In addition, the laminating device 1 of the present embodiment includes: a bonding portion 50 having a roller for overlapping and bonding a plurality of members; a conveying portion 20 including a first conveying portion (a first pulling roller 21, a second pulling roller 22, and the bonding portion 50) for conveying the first member 101 to the bonding portion 50 and a second conveying portion (a third pulling roller 23, a fourth pulling roller 24, and the bonding portion 50) for conveying the second member 102 and the third member 103 to the bonding portion 50; and a control portion 90. The control portion 90 performs the following first bonding operation (S11): conveys the first member 101 to the bonding portion 50 by the first conveying portion, conveys the second member 102 to the bonding portion 50 by the second conveying portion, and bonds the first member 101 and the second member 102. After the first bonding operation, in a state where the first member 101 and the second member 102 are held by the bonding portion 50, the following second bonding operation (S14 and S17) is performed: conveys the third member 103 by the second conveying portion so that the front end 123 of the third member 103 approaches the rear end 122 of the second member 102, and after conveying the third member 103, bonds the first member 101 and the third member 103.

[0128] In the laminating device 1 configured as described above, when the first member 101 has a first adhesive layer 104 on the bonding surface 108 and the second member 102 and the third member 103 are bonded to the bonding surface 108 of the first member 101, the first member 101 and the second member 102 are bonded. In a state where the first member 101 and the second member 102 are held by the bonding portion 50, the front end 123 of the third member 103 is brought close to the rear end 122 of the second member 102, and the first member 101 and the third member 103 are bonded. As a result, the gap between the second member 102 and the third member 103 is reduced, and contact between the first adhesive layer 104 of the first member 101 and the components inside the bonding portion 50 can be reduced. In addition, in this structure, the first member 101, the second member 102, and the third member 103 do not necessarily have to overlap.

[0129] In addition, in the first bonding operation, the control unit 90 stops the operation of the bonding unit 50 after bonding the first part including the front end of the first member 101 and the second member 102 (S11). In the second bonding operation, the bonding of the first member 101 to the second part, which is the part obtained by removing the first part from the second member 102, and the bonding of the first member 101 to the third member 103 are performed in a continuous operation (S16 and S17). Therefore, after bonding the first part of the first member 101 and the second member 102, the operation of the bonding unit 50 is stopped, and then, the bonding of the first member 101 to the second part of the second member 102 and the bonding of the first member 101 to the third member 103 are continuously performed. As a result, the gap between the second member 102 and the third member 103 is reduced, and the contact between the first adhesive layer 104 of the first member 101 and the components in the bonding unit 50 can be reduced.

[0130] [Modification Example]

[0131] Regarding the laminating device 1 of the above-described embodiment, various modification examples can be configured. Figure 8 The laminating device 2 according to the shown modification example is a device obtained by changing the positions and directions D1 to D4 of the first bonding roller 51 and the second bonding roller 52 in the laminating device 1.

[0132] In the bonding unit 50 of the laminating device 2, the first bonding roller 51 is spaced apart by an interval corresponding to the thickness of the laminated product 100 and is located above the second bonding roller 52 in the vertical direction 7 and behind the second bonding roller 52 in the front-rear direction 8. The first pulling roller 21 and the second pulling roller 22 are located above the bonding unit 50 in the vertical direction 7 and at a slightly rearward position of the bonding unit 50 in the front-rear direction 8. The second cutting unit 70, the first discharging roller 25, and the second discharging roller 26 are located above the bonding unit 50 in the vertical direction 7 and in front of the bonding unit 50 in the front-rear direction 8. The angle θ1 formed by the direction D1 and the direction D3 is an acute angle. The angle θ2 formed by the direction D2 and the direction D3 is greater than 180°.

[0133] As Figure 9 shown, in the laminating device 2, the rear end 122 of the second member 102 separates from the outer peripheral surface of the second bonding roller 52 and floats from the outer peripheral surface of the second bonding roller. A space 63 for floating the rear end 122 of the second member 102 that has passed through the first guiding member 61 is located on the side where the first member 101 and the third member 103 enter the bonding unit 50 (in Figure 9 it is the lower left part of the first bonding roller 51 and the second bonding roller 52). When the third member 103 is conveyed toward the bonding unit 50, the rear end 122 of the second member 102 is in a floating state within the space 63, so the third member 103 enters above the second member 102.

[0134] Therefore, the bonding portion 50 bonds the first member 101, the second member 102, and the third member 103 in a state where they are overlapped in the order of the first member 101, the third member 103, and the second member 102 between the first bonding roller 51 and the second bonding roller 52. Thus, in the bonding portion 50, the three members 101 to 103 are bonded in a state where they are overlapped in the order of the first member 101, the third member 103, and the second member 102. Thereby, since the front end 123 of the third member 103 supplied from the upstream is conveyed between the bonding surface 108 having the first adhesive layer 104 of the first member 101 and a part of the second member 102 including the rear end 122, the front end 123 of the third member 103 can be made to abut against a position upstream of the bonding of the first member 101 and the second member 102. Thereby, the accuracy of the overlapping distance can be improved.

[0135] The laminating apparatus of the modified example may also include a cutting portion 40 including a moving blade that moves in the vertical direction 7 and a fixed blade opposed to the moving blade, instead of the cutting portion 40 including the cutter carriage 41 and the cutter 42. The laminating apparatus of the modified example may not include the second cutting portion 70. In this case, the member formed by bonding the three members 101 to 103 is discharged from the discharge port 14 in an uncut state. The user cuts the discharged member outside the laminating apparatus, for example, using scissors.

[0136] The laminating apparatus according to the modified example may also include a bonding portion including one bonding roller, instead of the bonding portion 50 including the first bonding roller 51 and the second bonding roller 52. By disposing one bonding roller at an appropriate position within the housing 11, the first member 101 pulled out from the first reel 111 can be bonded to the third member 103 that has passed through the recording portion 30 and the cutting portion 40 using one bonding roller. The laminating apparatus according to the modified example may not include the first guide member 61. The laminating apparatus according to the modified example may not include the second guide member 62. The laminating apparatus according to the modified example may not include the first discharge roller 25 and the second discharge roller 26.

[0137] The laminating apparatus according to the modified example may also include other sensors instead of the medium sensor 35 as the first sensor portion for detecting the rear end 122 of the second member 102. The laminating apparatus according to the modified example may also include other sensors instead of the medium sensor 35 as the second sensor portion for detecting the front end 123 of the third member 103. The first sensor portion and the second sensor portion may be a shared sensor or different sensors. The first sensor portion and the second sensor portion may be sensors of the same type or different types.

[0138] The laminating apparatus according to the modification example may also include a sensor that is not mounted on the carriage 31 and does not move (hereinafter referred to as a "fixed sensor") instead of the medium sensor 35. The type of the fixed sensor can be arbitrary. For example, the fixed sensor can also be an optical sensor including a light-emitting element and a light-receiving element, similar to the medium sensor 35. Such an optical sensor is provided above or below the conveying path 15. Alternatively, the fixed sensor can also be a contact sensor that contacts the left end or the right end of the first member 101 to detect the end of the first member 101. Such a contact sensor is provided on the left or right side of the conveying path 15.

[0139] The laminating apparatus according to the modification example may also include a bonding portion including a belt instead of the bonding portion including the bonding rollers. The angle θ1 formed by the direction D1 and the direction D2 is preferably an obtuse angle, but in the laminating apparatus according to the modification example, the angle θ1 can be 90°, or can be an acute angle.

[0140] The laminating apparatus according to the modification example may also include a bonding portion including a heating roller or a pair of heating rollers instead of the bonding portion 50. In this case, the first adhesive layer 104 of the first member 101 will have adhesiveness by being heated by the heating roller or the pair of heating rollers. In addition, the bonding portion of the laminating apparatus according to the modification example may include other rollers and the like required for bonding a plurality of members in addition to (or instead of) the first bonding roller 51 and the second bonding roller 52.

[0141] In the laminating apparatus 1 according to the above-described embodiment, the second member 102 is the downstream portion of the two portions obtained by cutting the third member 103 by the cutting portion 40, but the second member is not limited thereto. In the laminating apparatus according to the modification example, the second member can also be, for example, a member different from the third member 103 and unrelated to the third member 103. The material of the second member can be the same as or different from that of the third member 103. In the laminating apparatus according to this modification example, the conveying unit conveys the second member and the third member 103 separately to the bonding portion.

[0142] The recording unit 30 of the laminating apparatus 1 according to the above-described embodiment has a recording head 32 that ejects ink and records an image in a so-called serial inkjet method, but the structure of the recording unit 30 is not limited thereto. The recording unit of the laminating apparatus according to the modification example can also have, for example, a fixed inkjet recording head and record an image in a so-called line head method. In addition, the recording unit of the laminating apparatus according to the modification example can also record an image in a so-called thermal head method. In addition, the recording unit of the laminating apparatus according to the modification example can also record an image by a so-called laser method of fixing toner on a recording medium using a laser.
