Description

Sheet conveying device

[0001] The present invention relates to a sheet transport device that transports a sheet pulled out from a roll.

[0002] Conventionally, laminating devices have been known that record an image on a first member pulled out from a first roll and then bond the first member with the image recorded to a second member pulled out from a second roll (for example, see Patent Document 1).

[0003] In the device described in Patent Document 1, a recording medium is pulled out from a recording medium roll. A printing unit records an image on the pulled out recording medium. A first cutting unit cuts the recording medium with the image recorded to a predetermined length. A laminating unit overlaps the cut recording medium with a laminating member. A pressurizing and heating roll heats the overlapped recording medium and laminating member. A second cutting unit separates the heated recording medium from the laminating member.

[0004] Japanese Patent Application Laid-Open No. 2003-211593

[0005] A roll wound with a recording medium or a laminating material is mounted by a user at a mounting position. One configuration for positioning the roll is to insert the shaft of a device into a hole located at the center of the roll's shaft. However, the mounting method of inserting the shaft of a device into a hole requires complicated work by the user, resulting in poor workability.

[0006] The present disclosure has been made in view of the above circumstances, and its object is to provide a means for easily mounting a roll on an apparatus.

[0007] (1) The present disclosure relates to a sheet transport device configured to accommodate a cartridge containing a roll of a wound sheet and having a first protrusion and a second protrusion, and configured to transport a sheet pulled from the roll. The sheet transport device includes a first frame and a second frame spaced apart from the first frame in a first direction along which the axis of the roll in the first mounting position extends. The first frame has a first guide portion that guides the first protrusion and a second guide portion that guides the second protrusion when the cartridge is mounted in the first mounting position.

[0008] Since the cartridge is guided by the two guide portions, the first guide portion and the second guide portion, the user can easily mount the cartridge in the sheet transport device.

[0009] (2) The sheet transport device may be configured so that the cartridge having the first protrusion on the axis of the roll can be attached thereto.

[0010] (3) The sheet transport device may be configured to be able to mount the cartridge having the second protrusion located farther from the axis of the roll than the first protrusion.

[0011] (4) The sheet transport device is configured so that the cartridge, in which the first convex portion and the second convex portion protrude along the first direction, is attached from above to below the sheet transport device through an upward opening, the first guide portion has two first guide surfaces that face each other at a distance in a second direction that intersects the first direction, the first guide surfaces extending downward from the opening, and the second guide portion has two second guide surfaces that face each other at a distance in the second direction, the second guide surfaces extending downward from the opening.

[0012] (5) The length of the first guide portion in the up-down direction may be shorter than the length of the second guide portion in the up-down direction.

[0013] (6) The first guide portion may have a first portion extending downward from the opening and a second portion extending downward from the first portion, and a third direction in which the first portion extends may intersect with a fourth direction in which the second portion extends.

[0014] (7) The fourth direction may be inclined more toward the center of the sheet transport device than the second direction.

[0015] (8) The second guide portion may have a third portion extending downward from the opening and a fourth portion extending downward from the third portion, and a fifth direction in which the third portion extends may intersect with a sixth direction in which the fourth portion extends.

[0016] (9) The sixth direction may be inclined more toward the center of the sheet transport device than the fifth direction.

[0017] (10) The sheet conveying device may further have a conveying roller and a pinch roller that convey the sheet extending from the roll, and a seventh direction connecting the axis of the conveying roller and the axis of the pinch roller may be inclined more toward the center of the sheet conveying device than the sixth direction.

[0018] (11) The cartridge may further include the pinch roller, an engaging portion that engages with the shaft of the transport roller, and a first biasing member that biases the pinch roller toward the transport roller.

[0019] The axis of the roll and the transport roller are accurately positioned, and the pinch roller is accurately positioned relative to the transport roller.

[0020] (12) The first guide portion may have a support surface that supports the cartridge at the first mounting position.

[0021] (13) The sheet transport device may further include a first locking portion that prevents the cartridge in the first mounting position from moving upward.

[0022] The cartridge is prevented from moving upward unexpectedly.

[0023] (14) The sheet transport device may further include a second biasing member that biases the cartridge in the first mounting position in the first direction.

[0024] The position of the cartridge in the first direction is stabilized.

[0025] (15) The sheet conveying device may further include a supply unit that supplies a laminating material, and a bonding unit that bonds the sheet and the laminating material together.

[0026] (16) The sheet conveying device may be configured to accommodate a laminate roll wound with the laminate material and to be capable of mounting a laminate cartridge having a third convex portion and a fourth convex portion at a second mounting position, and the first frame may have a third guide portion that guides the third convex portion and a fourth guide portion that guides the fourth convex portion when the laminate cartridge is mounted.

[0027] (17) The sheet conveying device further includes a first locking portion that prevents the cartridge at the first mounting position from moving upward, and a second locking portion that prevents the laminate cartridge at the second mounting position from moving upward, and the first mounting position and the second mounting position are spaced apart in a front-to-rear direction that is along the direction in which the first frame extends and perpendicular to the first direction, and the first locking portion and the second locking portion do not have to be located between the axis of the roll and the axis of the laminate roll in the front-to-rear direction.

[0028] The present disclosure may be understood as an image recording apparatus including the sheet conveying device and a recording unit that records an image on the sheet.

[0029] According to the present invention, the user can easily load the roll into the device.

The up-down direction, the front-rear direction, and the left-right direction are perpendicular to one another. The left-right direction is an example of a first direction. The front-rear direction is an example of a second direction.

[0032] [Overview of Laminating Apparatus 1] The laminating apparatus 1 creates a finished laminated product 100 by bonding a first member 101 and a second member 102 together. As shown in FIG. 1A, the laminating apparatus 1 has a housing 11 and a cover 12. The housing 11 is a rectangular box with no top surface. As shown in FIG. 2, the housing 11 has an opening 17 at the top. The cover 12 is located on top of the housing 11 and closes the opening 17. The rear wall of the housing 11 and the rear wall of the cover 12 are connected by a hinge 18. The laminating apparatus 1 is an example of an image recording apparatus and a sheet conveying apparatus. The first member 101 is an example of a sheet. The second member 102 is an example of a laminating member.

[0033] The cover 12 is opened and closed by a user's operation. Fig. 1A shows the cover 12 with the opening 17 closed. Fig. 2 shows the cover 12 with the opening 17 open. The housing 11 and the cover 12 define the internal space of the laminating device 1. The components that make up the laminating device 1 are located in the internal space of the laminating device 1.

[0034] The laminating device 1 has an operation unit 13 and a display unit 14. The operation unit 13 and the display unit 14 are located on the front wall 15 of the housing 11. The housing 11 has an outlet 16. The outlet 16 is located on the front wall 15 of the housing 11 below the operation unit 13 and the display unit 14. The finished laminated product 100 is discharged to the outside from the outlet 16.

[0035] As shown in Figures 2 to 5 and 7, the first member 101 is wound around a cylindrical first shaft 112 having a flange 113 to form a first roll 111. The first roll 111 is housed in a first cartridge 114 and attached to the laminating apparatus 1. The second member 102 is wound around a cylindrical second shaft 122 having a flange 123 to form a second roll 121. The second roll 121 is housed in a second cartridge 124 and attached to the laminating apparatus 1. The first roll 111 is an example of a roll. The second roll 121 is an example of a laminating roll.

[0036] 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 sheet having a first adhesive layer 103 on one surface of a tape layer 104 and a second adhesive layer 105 on the other surface of the tape layer 104. The first adhesive layer 103 faces radially inward in the second roll 121. The one surface of the tape layer 104 is the surface on the first member 101 side in the finished laminate 100. A release sheet 106 is located on the opposite side of the tape layer 104 with the second adhesive layer 105 sandwiched therebetween.

[0037] The first member 101 and the second member 102 may be made of any material. The second member 102 may be made of, for example, a resin material such as PET or PVC (polyvinyl chloride), synthetic paper such as Yupo paper (registered trademark), or a metal material. 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, an adhesive layer on the other surface, or both surfaces, or neither surface may have an adhesive layer. 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.

[0038] 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.

[0039] As shown in FIGS. 3 and 4 , the laminating apparatus 1 includes a recording unit 30, first to fourth conveying rollers 41 to 44, a laminating unit 50, a first cutting unit 61, and a second cutting unit 62. The recording unit 30, the first to fourth conveying rollers 41 to 44, the laminating unit 50, the first cutting unit 61, and the second cutting unit 62 are supported by a left frame 77 and a right frame 78, which are positioned apart in the left-right direction within the internal space of the housing 11. In other words, the recording unit 30, the first to fourth conveying rollers 41 to 44, the laminating unit 50, the first cutting unit 61, and the second cutting unit 62 are positioned between the left frame 77 and the right frame 78 in the left-right direction. The left frame 77 and the right frame 78 are, for example, flat steel plates. The left frame 77 is an example of a first frame, and the right frame 78 is an example of a second frame.

[0040] The laminating apparatus 1 includes a control unit and various motors. A first transport path 48 and a second transport path 49 are formed in the internal space of the housing 11. The first transport path 48 and the second transport path 49 are spaces partitioned by guide members (not shown) and the like. A first member 101 unwound from a first roll 111 travels through the first transport path 48, passing through the recording unit 30, the first cutting unit 61, and the laminating unit 50, before reaching the second cutting unit 62. The direction in which the first member 101 advances is the transport direction 19. A second member 102 unwound from a second roll 121 travels through the second transport path 49, passing through the laminating unit 50, before reaching the second cutting unit 62.

[0041] [Recording Unit 30] The recording unit 30 is located downstream of the first roll 111 in the conveying direction 19 of the first conveying path 48. The recording unit 30 is located below the first roll 111 and the second roll 121 in the up-down direction and behind the first cutting unit 61 in the front-rear direction. The recording unit 30 has a carriage 31 and a recording head 32. Although not shown in the figures, two guide rails extending in the left-right direction are located in the internal space of the housing 11. The carriage 31 is placed on the two guide rails. The carriage 31 receives driving force from the CR motor and moves in the left-right direction.

[0042] The recording head 32 is mounted on the carriage 31. The recording head 32 has a plurality of nozzles 33. The lower surface of the recording head 32 is a nozzle surface. The plurality of nozzles 33 are located on the nozzle surface. The recording head 32 moves left and right as the carriage 31 moves. A platen 34 is located below the recording head 32. The platen 34 supports the first member 101. While moving left and right, the recording head 32 selectively ejects ink downward from the nozzles 33. The ink ejected from the nozzles 33 adheres to the recording surface 107 of the first member 101. In this way, the recording unit 30 records an image on the recording surface 107 of the first member 101 pulled out from the first roll 111.

[0043] [First to fourth conveyance rollers 41 to 44] The first conveyance roller 41 is located above the second conveyance roller 42 in the up-down direction and behind the second conveyance roller 42 in the front-to-back direction. The second conveyance roller 42 is located behind the recording unit 30 in the front-to-back direction. The third conveyance roller 43 and the fourth conveyance roller 44 are located between the recording unit 30 and the laminating unit 50 in the front-to-back direction. The fourth conveyance roller 44 is located in front of the third conveyance roller 43 in the front-to-back direction.

[0044] The first conveying roller 41 includes a first roller 411 and a second roller 412. The first roller 411 is supported by the left frame 77 and the right frame 78 in the housing 11. The second roller 412 is supported by the first cartridge 114 (see FIG. 5 ). The first roller 411 is positioned diagonally below and in front of the second roller 412. The first member 101 is held between the first roller 411 and the second roller 412. The first roller 411 receives a driving force from a conveying motor and rotates about an axis extending in the left-right direction. The first member 101 is conveyed in the conveying direction 19 by the rotation of the second roller 412. When the first member 101 is conveyed in the conveying direction 19, the second roller 412 rotates about an axis extending in the left-right direction. The first roller 411 is an example of a conveying roller. The second roller 412 is an example of a pinch roller. The facing direction 20 connecting the axis of the first roller 411 and the axis of the second roller 412 is an example of the seventh direction.

[0045] The second conveying rollers 42 include a third roller 421 and a fourth roller 422. The third roller 421 and the fourth roller 422 are supported by the left frame 77 and the right frame 78 (see FIG. 5 ) of the housing 11. The third roller 421 is located directly above the fourth roller 422. The first member 101 is held between the third roller 421 and the fourth roller 422. The fourth roller 422 receives a driving force from the conveying motor and rotates around an axis extending in the left-right direction. The rotation of the fourth roller 422 conveys the first member 101 in the conveying direction 19. When the first member 101 is conveyed in the conveying direction 19, the third roller 421 rotates around an axis extending in the left-right direction.

[0046] The third conveyor rollers 43 include a fifth roller 431 and a sixth roller 432. The fourth conveyor rollers 44 include a seventh roller 441 and an eighth roller 442. The configurations and functions of the third conveyor rollers 43 and the fourth conveyor rollers 44 are the same as those of the second conveyor rollers 42, and therefore detailed description thereof will be omitted.

[0047] Of the two rollers constituting the first to fourth conveying rollers 41 to 44, any one of them may receive the driving force from the conveying motor.

[0048] [Laminating Unit 50] As shown in FIGS. 3 and 4 , the laminating unit 50 is located downstream of the recording unit 30 in the conveying direction 19 of the first conveying path 48. The laminating unit 50 is located between the first cutting unit 61 and the second cutting unit 62 in the front-rear direction. The laminating unit 50 has a first laminating roller 51 and a second laminating roller 52. The first laminating roller 51 is supported by the left frame 77 and the right frame 78 of the housing 11. The second laminating roller 52 is supported by the second cartridge 124 (see FIG. 6 ). The second laminating roller 52 is located diagonally above and rearward of the first laminating roller 51. The first member 101 and the second member 102 pass 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, and the laminating surface 109 of the first member 101 faces downward. Therefore, the first laminating roller 51 is located on the release sheet 106 side of the second member 102 .

[0049] The first laminating roller 51 receives a driving force from a laminating motor and rotates about an axis extending in the left-right direction. The rotation of the first laminating roller 51 causes the first member 101 and the second member 102 to be conveyed in the conveying direction 19. When the first member 101 and the second member 102 are conveyed in the conveying direction 19, the second laminating roller 52 also rotates about an axis extending in the left-right direction.

[0050] The second laminating roller 52 is biased toward the first laminating roller 51 by a coil spring 147. The first laminating roller 51 and the second laminating roller 52 are gripped by the first member 101 and the second member 102. This brings the recording surface 107 of the first member 101 and the laminating surface 109 of the second member 102 into close contact with each other, and the first member 101 and the second member 102 are laminated together.

[0051] 3 and 4 , the first cutting unit 61 is located downstream of the recording unit 30 in the conveying direction 19 of the first conveying path 48. The first cutting unit 61 is located between the third conveying roller 43 and the fourth conveying roller 44 in the front-to-rear direction. The first cutting unit 61 cuts the first member 101 between the second conveying roller 42 and the bonding unit 50. The second cutting unit 62 is located downstream of the bonding unit 50 in the conveying direction 19 of the first conveying path 48. The second cutting unit 62 is located in front of the bonding unit 50 in the front-to-rear direction. The second cutting unit 62 simultaneously cuts the first member 101 and the second member 102 that have been bonded together in the bonding unit 50.

[0052] The first cutting unit 61 has any configuration capable of cutting the first member 101. The second cutting unit 62 has any configuration capable of cutting the first member 101 and the second member 102. The first cutting unit 61 and the second cutting unit 62 may include, for example, a cutter carriage that receives a driving force from a cutting motor and moves in the left-right direction, and a cutter mounted on the cutter carriage, or may include a moving blade that receives a driving force from the cutting motor and moves in the up-down direction, and a fixed blade that faces the moving blade.

[0053] [First Cartridge 114, Second Cartridge 124] The first cartridge 114 houses a first roll 111 around which the first member 101 is wound. The first roll 111 is detachable from the first cartridge 114. The second cartridge 124 houses a second roll 121 around which the second member 102 is wound. The second roll 121 is detachable from the second cartridge 124. The second roll 121 is wound with the first adhesive layer 103 of the second member 102 on the inside and the release sheet 106 on the outside. The first cartridge 114 is an example of a cartridge. The second cartridge 124 is an example of a laminate cartridge and a supply unit.

[0054] [First Cartridge 114] As shown in FIGS. 3, 4, and 5, the first cartridge 114 has a second roller 412, a storage portion 116, and a guide 118.

[0055] The storage section 116 is a box with an opening at the top. The storage section 116 has a left wall 116L and a right wall 116R that are separated in the left-right direction. The first roll 111, the second roller 412, and the guide 118 are located in the space between the left wall 116L and the right wall 116R in the left-right direction.

[0056] The first roll 111 is housed in the internal space of the housing section 116 with its axis extending in the left-right direction. As shown in Fig. 5 , the first roll 111 is housed in the internal space of the housing section 116 with both left-right ends of the first roll 111 sandwiched between flanges 113. When housed in the internal space of the housing section 116, the first roll 111 is rotatable about its axis.

[0057] As shown in FIG. 6 , the first cartridge 114 has a spring 130. The spring 130 is located between the right flange 113 of the first roll 111 and the right wall 116R of the first cartridge 114. The first roll 111 is biased leftward by the spring 130. Therefore, the left flange 113 of the first roll 111 abuts against the left wall 116L of the storage section 116. In other words, the first roll 111 is positioned in the left-right direction based on the left wall 116L.

[0058] 3, 4, and 6, the first cartridge 114 has a protrusion 191L, a protrusion 192L, a protrusion 191R, and a protrusion 192R. The protrusions 191L ​​and 192L are located on the left wall 116L of the storage portion 116 and protrude to the left. The protrusions 191R and 192R are located on the right wall 116R of the storage portion 116 and protrude to the right. The protrusions 191L ​​and 191R are an example of a first protrusion. The protrusions 192L and 192R are an example of a second protrusion.

[0059] The protrusions 191L ​​and 191R are on the same axis. The axis of the first roll 111 is positioned on the axis of the protrusions 191L ​​and 191R.

[0060] The protrusions 192L and 192R are on the same straight line. In the up-down direction, the protrusions 192L and 192R are positioned lower than the protrusions 191L ​​and 191R. In other words, the protrusions 192L and 192R are spaced apart from the axis of the first roll 111.

[0061] As shown in FIG. 6 , the protrusion 192R includes an outer tube 160, an inner tube 161, and a coil spring 162. The outer tube 160 protrudes rightward from the right wall 116R of the housing 116. The inner tube 161 is located within the interior space of the outer tube 160 and is guided by the outer tube 160 to move left and right. The outer diameter of the inner tube 161 is slightly smaller than the inner diameter of the outer tube 160. A coil spring 162 is located within the interior space of the outer tube 160. Both ends of the coil spring 162 abut against the right wall 116R and the inner tube 161. The inner tube 161 is biased rightward by the coil spring 162. The right end of the inner tube 161 is located to the right of the right end of the outer tube 160. The coil spring 162 is an example of a second biasing member.

[0062] As shown in FIG. 5 , a guide 118 is located near the lower end of the storage section 116. The guide 118 is a plate-shaped member extending in the left-right direction. The guide 118 has pivot shafts 117 at its left and right ends. The pivot shafts 117 are supported by the left wall 116L and the right wall 116R of the storage section 116, respectively. The guide 118 is rotatable around the pivot shafts 117. The guide 118 has ribs 120 that protrude upward and extend in the front-rear direction. Multiple ribs 120 are arranged at intervals in the left-right direction. The number and spacing of the ribs 120 are set appropriately. When the guide 118 is located at the position shown in FIG. 5 , the first member 101 pulled out from the first roll 111 is supported from below by the guide 118. When the guide 118 is located at the position shown by the dashed line in FIG. 5 , the bottom of the first roll 111 is open. This allows the user to access the first roll 111 from below and pull out the first roll 111 or the first member 101 .

[0063] 5 and 6 , the second roller 412 is located behind the guide 118. The second roller 412 is supported by the left wall 116L and the right wall 116R of the storage section 116 so as to be rotatable about its axis in the left-right direction. The second roller 412 is located above the first member 101 drawn out from the first roll 111. The left wall 116L and the right wall 116R of the storage section 116 have elongated holes 141 through which the shaft of the second roller 412 can be inserted, the elongated holes 141 extending along the opposing direction 20 in which the first roller 411 and the second roller 412 face each other. Therefore, the second roller 412 is movable along the opposing direction 20.

[0064] The first cartridge 114 has a coil spring 142 and an engagement groove 143. The coil spring 142 is located in the elongated hole 141. The coil spring 142 biases the second roller 412 downward in the facing direction 20. The engagement groove 143 is located at the lower ends of the left wall 116L and the right wall 116R of the storage portion 116, below the elongated hole 141 in the facing direction 20. The engagement groove 143 opens downward. The engagement groove 143 engages with the shaft of the first roller 411. This positions the left wall 116L and the right wall 116R of the storage portion 116 relative to the shaft of the first roller 411, and as a result, the first roller 411 and the second roller 412 are positioned so that their axes are parallel and opposed to each other. The engagement groove 143 is an example of an engagement portion. The coil spring 142 is an example of a first biasing member.

[0065] 4 and 5, the first cartridge 114 has a shaft 154. The shaft 154 is located in the storage portion 116. The shaft 154 is supported by a left wall 116L and a right wall 116R in the storage portion 116, and its axial direction extends along the left-right direction. The right end of the shaft 154 protrudes rightward from the right wall 116R.

[0066] As shown in FIG. 4 , the laminating device 1 has a lock lever 155 and a coil spring 156. The lock lever 155 is located in the internal space of the housing 11. The lock lever 155 is hook-shaped and can rotate around an axis at its lower end that runs in the left-right direction. When the first cartridge 114 is attached to the housing 11, the lock lever 155 engages with the upper side of the shaft 154, preventing the first cartridge 114 from moving upward. The lock lever 155 can be operated by a user using a known structure such as a slide cam. The lock lever 155 is an example of a first locking unit.

[0067] As shown in Fig. 4, the lock lever 155 is biased in the clockwise direction in Fig. 4 by a coil spring 156. Due to the biasing force of the coil spring 156, the lock lever 155 biases the shaft 154 in the opposing direction 20. As a result, the second roller 412 is biased toward the first roller 411.

[0068] 5, the first cartridge 114 has a handle 115. The handle 115 protrudes upward from the front end of the storage portion 116. The handle 115 has an opening, which allows a user to hold the first cartridge 114 with their hands.

[0069] [Second Cartridge 124] As shown in FIGS. 3, 4 and 7, the second cartridge 124 has the second laminating roller 52, a housing portion 131, a movable guide 132, a fixed guide 133, and a cover 134.

[0070] The storage section 131 is a box with an upward opening. The storage section 131 has a left wall 131L and a right wall 131R that are separated in the left-right direction. In the left-right direction, the second laminating roller 52, the movable guide 132, the fixed guide 133, and the cover 134 are located in the space between the left wall 131L and the right wall 131R.

[0071] The second roll 121 is housed in the internal space of the housing section 131 with its axis extending in the left-right direction. As shown in Fig. 6 , the second roll 121 is housed in the internal space of the housing section 131 with both left-right ends of the second roll 121 sandwiched between flanges 123. When housed in the internal space of the housing section 131, the second roll 121 is rotatable about its axis.

[0072] As shown in FIG. 8 , the second cartridge 124 has a spring 129. The spring 129 is located between the right flange 123 of the second roll 121 and a right wall 131R of the second cartridge 124. The second roll 121 is biased leftward by the spring 129. Therefore, the left flange 123 of the second roll 121 abuts against the left wall 131L of the storage section 131. In other words, the second roll 121 is positioned in the left-right direction based on the left wall 131L. Here, the spring 129 may be included in the second roll 121, or the second roll 121 may be a component that is detachable from the second cartridge 124.

[0073] As shown in FIGS. 3, 4, and 8, the second cartridge 124 has a protrusion 193L and a protrusion 193R. The protrusion 193L is located on the left wall 131L of the storage portion 131 and protrudes to the left. The protrusion 193R is located on the right wall 131R of the storage portion 131 and protrudes to the right. The protrusions 193L and 193R are on the same axis. The axis of the second roll 121 roughly overlaps with the axes of the protrusions 193L and 193R. The protrusion 193L is supported by the left frame 77. The protrusion 193R is supported by the right frame 78. The protrusions 193L and 193R are examples of third protrusions. Here, the protrusion 193L does not necessarily have to protrude leftward beyond the left frame 77, and the protrusion 193R does not necessarily have to protrude rightward beyond the right frame 78. Furthermore, the convex portions 193L and 193R and the cylindrical second shaft 122 having the flange 123 do not have to be on the same axis.

[0074] As shown in Figures 3, 4, and 8, the second cartridge 124 has protrusions 194L and 194R. Protrusion 194L is located on the left wall 131L of the storage portion 131 and protrudes to the left. Protrusion 194R is located on the right wall 131R of the storage portion 131 and protrudes to the right. Protrusions 194L and 194R are on the same axis. Protrusions 194L and 194R are located below protrusions 193L and 193R. In other words, protrusions 194L and 194R are spaced apart from the axis of the second roll 121. Protrusions 194L and 194R are examples of fourth protrusions.

[0075] As shown in FIG. 8 , the protrusion 194R has an outer cylinder 163, an inner cylinder 164, and a coil spring 165. The outer cylinder 163 protrudes rightward from the right wall 131R of the accommodation portion 131. The inner cylinder 164 is located in the internal space of the outer cylinder 163 and is guided by the outer cylinder 163 to be movable left and right. The outer diameter of the inner cylinder 164 is slightly smaller than the inner diameter of the outer cylinder 163. The coil spring 165 is located in the internal space of the outer cylinder 163. Both ends of the coil spring 165 abut against the right wall 131R and the inner cylinder 164. The inner cylinder 164 is biased rightward by the coil spring 165. The right end of the inner cylinder 164 is located to the right of the right end of the outer cylinder 163.

[0076] 7, a movable guide 132 is located near the lower end of the storage section 131. The movable guide 132 is supported between a left wall 131L and a right wall 131R of the storage section 131 so as to be rotatable about a shaft 135.

[0077] The movable guide 132 is a plate-shaped member having upper and lower surfaces extending in the left-right direction. The movable guide 132 has a first rib 136 that protrudes upward from the upper surface and extends in the front-rear direction. Multiple first ribs 136 are arranged at intervals in the left-right direction. The number and spacing of the first ribs 136 are set appropriately. In this embodiment, the first rib 136 is shaped as two separate parts in the front-rear direction, but it may also be shaped as a continuous part in the front-rear direction. The upper end surface of the first rib 136 faces the first adhesive layer 103 of the second member 102.

[0078] The movable guide 132 has spurs 137. The spurs 137 are located between multiple first ribs 136. The spurs 137 are circular plates whose outer peripheral surface is pointed in a multiple-peaked shape when viewed from the axial direction. In this embodiment, four spurs 137 are located at intervals in the left-right direction in the front portion of the first rib 136. Five spurs 137 are located at intervals in the left-right direction in the front portion of the first rib 136. The number, arrangement, and spacing of the spurs 137 are set appropriately. The peak-shaped tips of the spurs 137 abut against the first adhesive layer 103 of the second member 102. The spurs 137 rotate as the second member 102 is transported in the transport direction 19.

[0079] 7, the fixed guide 133 is located near the lower end of the storage section 131 and above the movable guide 132. The fixed guide 133 is supported by a left wall 131L and a right wall 131R of the storage section 131. The fixed guide 133 faces the movable guide 132 in the vertical direction.

[0080] The fixed guide 133 is a member that is elongated in the left-right direction. The fixed guide 133 has second ribs 145 that protrude downward and extend in the up-down direction. Multiple second ribs 145 are arranged at intervals in the left-right direction. The second ribs 145 are located between adjacent first ribs 136 in the left-right direction on the movable guide 132. The lower end surfaces of the second ribs 145 face the release sheet 106 of the second member 102.

[0081] The rotation of the movable guide 132 causes the distance in the up-down direction between the first rib 136 and the second rib 145 to vary. When the rotation of the movable guide 132 causes at least a portion of the first rib 136 to be positioned between the base (upper end) and end (rear end) of the second rib 145, that is, when the first rib 136 and the second rib 145 overlap in the up-down direction, the second member 102 is less likely to pass between the movable guide 132 and the fixed guide 133. As a result, the leading end of the second member 102 unwound from the second roll 121 is sandwiched between the first rib 136 and the second rib 145.

[0082] When the movable guide 132 rotates so that the entire first rib 136 is not positioned between the base and end of the second rib 145 in the vertical direction, the second member 102 unwound from the second roll 121 passes between the movable guide 132 and the fixed guide 133.

[0083] 7 , the second laminating roller 52 is located rearward of the fixed guide 133 in the front-rear direction. The second laminating roller 52 is supported by a left wall 131L and a right wall 131R of the housing section 131 so as to be rotatable about its axis in the left-right direction. The left wall 131L and the right wall 131R of the housing section 131 have elongated holes 146 through which the shaft of the second laminating roller 52 can be inserted, the elongated holes 146 extending along the opposing direction 21 in which the first laminating roller 51 and the second laminating roller 52 face each other. Therefore, the second laminating roller 52 is movable along the opposing direction 21.

[0084] The second cartridge 124 has a coil spring 147. The coil spring 147 is located in the elongated hole 146. The coil spring 147 biases the second laminating roller 52 toward the first laminating roller 51 in the up-down direction. Engagement grooves 148 that open downward are located at the lower ends of the left wall 131L and right wall 131R of the storage section 131, below the elongated hole 146 in the facing direction 21. The engagement grooves 148 engage with the shaft of the first laminating roller 51. This positions the left wall 131L and right wall 131R of the storage section 131 relative to the shaft of the first laminating roller 51, and as a result, the first laminating roller 51 and the second laminating roller 52 are positioned so that their axes are parallel and opposed to each other in the facing direction 21.

[0085] 7 , the second cartridge 124 has rollers 149. The rollers 149 are located above and behind the second laminating roller 52. The rollers 149 are supported by the left wall 131L and the right wall 131R of the containing portion 131 so as to be rotatable about their axis in the left-right direction. The rollers 149 face the release sheet 106 of the second member 102.

[0086] 7 , the cover 134 is located behind the roller 149 and below the second roll 121. The cover 134 covers the rear of the second member 102 between below the second roll 121 and above the movable guide 132. The cover 134 faces the first adhesive layer 103 of the second member 102.

[0087] As shown by the dashed lines in Fig. 7, the cover 134 rotates around its upper end as an axis, with its lower end moving rearward. When the cover 134 is in the position shown by the dashed lines in Fig. 6, the first adhesive layer 103 of the second member 102 is exposed rearward, making it easy to access the second member 102 from the rear of the second cartridge 124. Although not shown in the figures, the surface of the cover 134 facing the first adhesive layer 103 of the second member 102 may be provided with a rib or a coating layer that has excellent releasability from the first adhesive layer 103.

[0088] 7, the second cartridge 124 has a shaft 151. The shaft 151 is located in the storage portion 131. The shaft 151 is supported by a left wall 131L and a right wall 131R in the storage portion 131, and the axial direction of the shaft 151 extends along the left-right direction. The right end of the shaft 151 protrudes rightward from the left wall 131L.

[0089] As shown in FIG. 4 , the laminating device 1 has a lock lever 152 and a coil spring 153. The lock lever 152 is located in the internal space of the housing 11. The lock lever 152 is hook-shaped and can rotate around an axis at its lower end that runs in the left-right direction. When the second cartridge 124 is attached to the housing 11, the lock lever 152 engages with the upper side of the shaft 151, preventing the second cartridge 124 from moving upward. The lock lever 152 can be operated by a user using a known structure such as a slide cam. The lock lever 152 is an example of a second locking section.

[0090] 4, the lock lever 152 is biased in the clockwise direction in FIG. 4 by a coil spring 153. The biasing force of the coil spring 153 causes the lock lever 152 to bias the shaft 151 in the opposing direction 21. As a result, the second laminating roller 52 is biased toward the first laminating roller 51.

[0091] 7, a handle 125 protrudes upward from the front end of the storage section 131. The handle 125 has an opening that allows the user to hold the second cartridge 124 with their hands.

[0092] 9 , the left frame 77 has a first guide portion 171, a second guide portion 172, a third guide portion 181, and a fourth guide portion 182. The right frame 78 has a first guide portion 171, a second guide portion 172, a third guide portion 181, and a fourth guide portion 182. Note that the first guide portion 171, the second guide portion 172, the third guide portion 181, and the fourth guide portion 182 of the right frame 78 are symmetrical to the first guide portion 171, the second guide portion 172, the third guide portion 181, and the fourth guide portion 182 of the left frame 77, and therefore the first guide portion 171, the second guide portion 172, the third guide portion 181, and the fourth guide portion 182 will be described here using the left frame 77 as an example.

[0093] The first guide portion 171 is a groove recessed leftward from the inner surface 77A of the left frame 77. The first guide portion 171 is defined by two first guide surfaces 173, 174 that face each other at a distance in the front-to-rear direction, and an end surface 175. The end surface 175 is flat. The first guide portion 171 has an opening 176 that opens upward. The first guide surfaces 173, 174 extend generally downward from the opening 176. The first guide surfaces 173, 174 guide the movement direction of the convex portion 191L. The end surface 175 is an example of a support surface.

[0094] The first guide portion 171 is broadly divided into an upper portion 171U and a lower portion 171L. The upper portion 171U extends downward from the opening 176 (an example of a third direction). The lower portion 171L extends from the lower end of the upper portion 171U in a direction intersecting the downward direction (an example of a fourth direction). The extension direction of the lower portion 171L is inclined from the lower end of the upper portion 171U toward the center of the housing 11 in the front-to-rear direction. A terminal surface 175 is located at the end of the extension direction of the lower portion 171L. The terminal surface 175 abuts against the protrusion 191L ​​to prevent the protrusion 191L ​​from moving downward and forward. The upper portion 171U is an example of a first portion. The lower portion 171L is an example of a second portion.

[0095] The second guide portion 172 is a groove recessed to the left from the inner surface 77A of the left frame 77. The second guide portion 172 is located rearward of the first guide portion 171. The second guide portion 172 is defined by two second guide surfaces 177, 178 that face each other and are spaced apart in the front-to-rear direction. The second guide portion 172 has an opening 179 that opens upward. The second guide surfaces 177, 178 extend generally downward from the opening 179. The second guide surfaces 177, 178 guide the movement direction of the convex portion 192L. The vertical length of the first guide portion 171 is shorter than the vertical length of the second guide portion 172.

[0096] The second guide portion 172 is roughly divided into an upper portion 172U and a lower portion 172L. The upper portion 172U extends downward from the opening 179 (an example of a fifth direction). The lower portion 172L extends from the lower end of the upper portion 172U in a direction intersecting the downward direction (an example of a sixth direction). The extension direction of the lower portion 172L is inclined from the lower end of the upper portion 172U toward the center of the housing 11 in the front-to-rear direction. The upper portion 172U is an example of a third portion. The lower portion 172L is an example of a fourth portion. The extension direction of the lower portion 172L is inclined toward the center of the housing 11 in the front-to-rear direction with respect to the opposing direction 20 connecting the axis of the first roller 411 and the axis of the second roller 412.

[0097] The third guide portion 181 is a groove recessed leftward from the inner surface 77A of the left frame 77. The third guide portion 181 is defined by two third guide surfaces 183, 184 that face each other with a gap in the front-to-rear direction, and an end surface 185. The third guide portion 181 has an opening 186 that opens upward. The third guide surfaces 183, 184 extend generally downward from the opening 186. The third guide surfaces 183, 184 guide the movement direction of the convex portion 191L.

[0098] The third guide portion 181 is roughly divided into an upper portion 181U and a lower portion 181L. The upper portion 181U extends downward from the opening 186. The lower portion 181L extends from the lower end of the upper portion 181U in a direction intersecting the downward direction. The extension direction of the lower portion 181L is inclined from the lower end of the upper portion 181U toward the center of the housing 11 in the front-to-rear direction. A terminal surface 185 is located at the end of the extension direction of the lower portion 181L. The terminal surface 185 abuts against the protrusion 193L to prevent the protrusion 193L from moving downward and rearward.

[0099] The fourth guide portion 182 is a groove recessed leftward from the inner surface 77A of the left frame 77. The fourth guide portion 182 is located forward of the third guide portion 181. The fourth guide portion 182 is defined by two fourth guide surfaces 187, 188 that face each other and are spaced apart in the front-to-rear direction. The fourth guide portion 182 has an opening 189 that opens upward. The fourth guide surfaces 187, 188 extend generally downward from the opening 189. The fourth guide surfaces 187, 188 guide the movement direction of the convex portion 194L.

[0100] The fourth guide portion 182 is roughly divided into an upper portion 182U and a lower portion 182L. The upper portion 182U extends downward from the opening 189. The lower portion 182L extends from the lower end of the upper portion 182U in a direction intersecting the downward direction. The extension direction of the lower portion 182L is inclined from the lower end of the upper portion 182U toward the center of the housing 11 in the front-to-rear direction.

[0101] [Installation of First Cartridge 114 and Second Cartridge 124] As shown in Fig. 5 , when the user holds the handle 115, the second roller 412 is located below the center of rotation of the first roll 111 until the first cartridge 114 is installed in the housing 11. As shown in Fig. 7 , when the user holds the handle 125, the movable guide 132 is located below the center of rotation of the second roll 121 until the second cartridge 124 is installed in the housing 11.

[0102] 2 to 4 and 9 , the opening 17 located at the top of the housing 11 has a size that allows the first cartridge 114 and the second cartridge 124 to pass through at the same time. The first cartridge 114 and the second cartridge 124 can be inserted through the single opening 17 from outside the housing 11 and attached to predetermined positions within the housing 11. The first cartridge 114 and the second cartridge 124 can be attached and detached to and from the housing 11 independently. Here, the opening 17 does not necessarily have to be a single opening, and may be divided into an opening for inserting the first cartridge 114 and an opening for inserting the second cartridge 124 at the center in the front-to-rear direction. In other words, the opening 17 may have a partition plate or the like.

[0103] The first cartridge 114 is inserted downward into the internal space of the housing 11. The first cartridge 114 is guided so that its movement in the front-rear direction is restricted by the protrusions 191L ​​and 191R entering the first guide portion 171 through the opening 176 of the first guide portion 171, and the first cartridge 114 is guided so that its movement in the front-rear direction is restricted by the protrusions 192L and 192R entering the second guide portion 172 through the opening 179 of the second guide portion 172. The first cartridge 114 is inserted downward while maintaining its posture by the two protrusions spaced apart in the front-rear direction, such as the protrusions 191L ​​and 192L, being guided. When the protrusions 191L ​​and 191R abut against the end surface 175 of the first guide portion 171 and the protrusions 192L and 192R abut against the lower end of the second guide portion 172, the first cartridge 114 is attached to the housing 11. The position of the first cartridge 114 at this time is an example of the first attachment position. The engagement groove 143 engages with the shaft of the first roller 411. The lock lever 155 engages with the shaft 154.

[0104] 3 and 4 , when the first cartridge 114 is in the first mounting position, the axis of the first roll 111 extends in the left-right direction. The first roll 111 is housed in the first cartridge 114 and mounted in the housing 11 with its axis extending in the left-right direction. The second roller 412 is biased by the coil spring 142 to abut against the first roller 411. In the first mounting position, the opposing direction 20 (seventh direction) connecting the axis of the first roller 411 and the axis of the second roller 412 is inclined toward the center of the housing 11 in the front-rear direction relative to the lower portion 172L of the second guide portion 172.

[0105] 2 to 4 and 9 , the second cartridge 124 is inserted downward into the internal space of the housing 11 by the projections 193L and 193R entering the third guide portion 181 through the opening 186 of the third guide portion 181, thereby being guided so that movement in the front-to-rear direction is limited, and the projections 194L and 194R entering the fourth guide portion 182 through the opening 189 of the fourth guide portion 182, thereby being guided so that movement in the front-to-rear direction is limited. The second cartridge 124 is inserted downward while maintaining its posture by the two projections 193L and 194L that are spaced apart in the front-to-rear direction being guided. When the projections 193L and 193R abut against the end surface 185 of the third guide portion 181 and the projections 194L and 194R abut against the lower end of the fourth guide portion 182, the second cartridge 124 is attached to the housing 11. The position of the second cartridge 124 at this time is an example of the second mounting position. The engagement groove 148 engages with the shaft of the first laminating roller 51. The lock lever 152 engages with the shaft 151.

[0106] 3 and 4 , when the second cartridge 124 is in the second installation position, the axis of the second roll 121 extends in the left-right direction. The second roll 121 is housed in the second cartridge 124 and installed in the housing 11 in an orientation in which the axis extends in the left-right direction. The second laminating roller 52 is biased by the coil spring 147 to abut against the first laminating roller 51. In the second installation position, the opposing direction 21 connecting the axis of the first laminating roller 51 and the axis of the second laminating roller 52 is inclined toward the center of the housing 11 in the front-to-rear direction more than the lower portion 182L of the fourth guide portion 182.

[0107] The first mounting position of the first cartridge 114 and the second mounting position of the second cartridge 124 are spaced apart in the front-rear direction. The lock levers 152 and 155 are not located between the axis of the first roll 111 and the axis of the second roll 121 in the front-rear direction.

[0108] As shown in FIG. 2 , the first cartridge 114 has a handle 115 for a user to grasp. The second cartridge 124 has a handle 125 for a user to grasp. The handles 115 and 125 have different shapes so that the user can easily distinguish them. When the first roll 111 is attached, the handle 115 is located between the front wall 15 of the housing 11 and the first shaft 112 in the front-rear direction. Almost the entire handle 115 is located above the opening 17. When the second roll 121 is attached, the handle 125 is located between the front wall 15 and the second shaft 122 in the front-rear direction. A portion of the handle 125 is located above the opening 17. The handles 115 and 125 may have the same shape. Also, at least a portion of the handles 115 and 125 may be located above the opening 17, or the entire handles 115 and 125 may be located below the opening 17.

[0109] When the first cartridge 114 and the second cartridge 124 are attached to the housing 11, the second roll 121 is located between the front wall 15 and the first roll 111 in the front-rear direction. The first shaft 112 is located above the second shaft 122 in the up-down direction. A portion of the first roll 111 and a portion of the second roll 121 are located above the opening 17. When the first roll 111 is attached, the cover 12 covers the portion of the first roll 111 located above the opening 17, and when the second roll 121 is attached, the cover 12 covers the portion of the second roll 121 located above the opening 17 and the opening 17. When two rolls are attached, the first shaft 112 and the second shaft 122 are located above the recording unit 30 and the laminating unit 50 in the up-down direction.

[0110] The first transport path 48 transports the first member 101 pulled out from the first roll 111 when it is attached to the first mounting position, below the first roll 111 in the up-down direction and behind the first shaft 112 in the front-to-rear direction. The second transport path 49 transports the second member 102 pulled out from the second roll 121 when it is attached to the second mounting position, below the second roll 121 in the up-down direction and in front of the second shaft 122 in the front-to-rear direction. When the first roll 111 is attached, the first member 101 wound around the first roll 111 is pulled out from in front of the first roll 111 in the front-to-rear direction.

[0111] [Lamination Process] The laminating apparatus 1 includes a control unit (not shown). When the control unit receives an instruction signal from a user to start the laminating process, the control unit drives the conveying motor to rotate the first conveying rollers 41 and the second conveying rollers 42, causing the first conveying rollers 41 and the second conveying rollers 42 to convey the first member 101.

[0112] Next, the control unit stops the conveyance of the first member 101 and drives the recording unit 30 to record an image on the first member 101. The control unit conveys the first member 101 until the leading end of the first member 101 on which the image has been recorded reaches the bonding unit 50, and drives the bonding motor to drive the bonding unit 50. The recording surface 107 of the first member 101 and the bonding surface 109 of the second member 102 are sandwiched by the bonding unit 50 and bonded to each other.

[0113] The control unit also causes the first cutting unit 61 to cut the first member 101 at a position upstream in the transport direction 19 from the area where the image is recorded.

[0114] The control unit transports the bonded first member 101 and second member 102 until the cutting position reaches below the second cutting unit 62, and after cutting by the second cutting unit 62, discharges the laminated finished product 100 from the discharge outlet 16.

[0115] [Operation and Effects of the Embodiment] According to the present embodiment, the first cartridge 114 is guided by two guide portions, the first guide portion 171 and the second guide portion 172, so that the user can easily attach the first cartridge 114 to the housing 11.

[0116] Furthermore, when the first cartridge 114 is attached, the engagement groove 143 engages with the axis of the first roller 411. This allows the second roller 412 to be accurately positioned relative to the first roller 411. Furthermore, the axis of the first roll 111 and the first roller 411 are accurately positioned.

[0117] Furthermore, the first cartridge 114 is prevented from unexpectedly moving upward by the lock lever 155 engaging with the shaft 154. Furthermore, the positions of the first roller 411 and the second roller 412 are stabilized, improving the conveyance accuracy.

[0118] Furthermore, the inner cylinder 161, which is biased by the coil spring 162, comes into contact with the second guide portion 172 at the protrusion 192R, thereby stabilizing the position of the first cartridge 114 in the left-right direction.

[0119] [Modifications] The first guide portion 171 and the second guide portion 172 do not have to be configured as portions of the left frame 77 and the right frame 78 that are recessed in one direction (outward) in the left-right direction. For example, the first guide portion 171 and the second guide portion 172 may be cutouts formed in the left frame 77 and the right frame 78, or may be configured by fixing a synthetic resin molded product with a recessed groove to the inner surface of the left frame 77 and the right frame 78.

[0120] Furthermore, the protrusions 191L ​​and 191R do not have to be positioned on the axis of the first roll 111. Furthermore, the protrusions 192L and 192R may be positioned on the axis of the first roll 111.

[0121] The vertical length, shape, and extending direction of the first guide portion 171 and the second guide portion 172 may be changed as appropriate. For example, the first guide portion 171 or the second guide portion 172 may extend straight downward. The end surface 175 may be a curved surface instead of a flat surface.

[0122] Furthermore, the second roller 412 may be supported by the left frame 77 and the right frame 78, rather than being located in the first cartridge 114. Furthermore, the engagement groove 143 may be omitted.

[0123] Additionally, the lock levers 152 and 155 may be omitted.
