[0018] Hereinafter, the present disclosure will be described based on the implementation mode. In each of the drawings, the same symbol is marked for the same component, and repeated descriptions are omitted. In addition, in this specification, "same", "identical", and "simultaneous" do not only refer to completely identical situations. For example, in this specification, "same", "identical", and "simultaneous" include situations that are the same in consideration of measurement errors. In addition, for example, in this specification, "same", "identical", and "simultaneous" include situations that are the same in consideration of manufacturing deviations of components.

[0019] In addition, for example, in this specification, "same", "identical", and "simultaneous" include the case where the same is within the range that does not impair the function. Therefore, for example, "the dimensions of both are the same" means that the difference between the dimensions of the two is within ±5% of the dimension of one, and particularly preferably within ±3%, taking into account measurement errors and manufacturing variations of components.

[0020] 1. Implementation Method 1

[0021] The printing device 11 is, for example, an inkjet printer that prints images such as text and photos by ejecting ink as an example of liquid onto paper, cloth F, etc. as an example of a medium P. In the present embodiment, when printing is performed on cloth F, the printing device 11 performs printing by ejecting ink onto the cloth F pasted on the adhesive sheet AS. Therefore, the cloth F pasted on the adhesive sheet AS is an example of the medium P. In the following description, the cloth F pasted on the adhesive sheet AS may be referred to as "paste-standard cloth F".

[0022] The adhesive sheet AS has a base material and an adhesive layer formed on the base material by an adhesive. As the base material, for example, high-quality paper can be used. As the adhesive constituting the adhesive layer, for example, an acrylic adhesive can be used. The adhesive layer of the adhesive sheet AS before the fabric F is attached is covered with a protective sheet SS. As the protective sheet SS, for example, cellophane, laminated paper with a resin film attached to one side or both sides, a resin film such as polyvinyl chloride, synthetic paper, etc. can be used.

[0023] In addition, in each of the drawings, X, Y, and Z represent three spatial axes that are orthogonal to each other. In this specification, the directions along these axes are referred to as the X-axis direction, the Y-axis direction, and the Z-axis direction. When the direction is specifically specified, the positive direction is referred to as "+", and the negative direction is referred to as "-", and the direction mark is described by using both positive and negative signs, and the direction pointed by the arrow mark in each of the drawings is referred to as the + direction, and the opposite direction of the arrow mark is referred to as the - direction.

[0024] In addition, the Z-axis direction indicates the direction of gravity, the +Z direction indicates vertically downward, and the -Z direction indicates vertically upward. In addition, the plane including the X-axis and the Y-axis is set as the XY plane, the plane including the X-axis and the Z-axis is set as the XZ plane, and the plane including the Y-axis and the Z-axis is set as the YZ plane for description. In addition, the XY plane becomes a horizontal plane. In addition, the three spatial axes of X, Y, and Z that are not limited to the positive direction and the negative direction are described as the X-axis, the Y-axis, and the Z-axis.

[0025] The X-axis direction is a direction intersecting the conveying direction of the medium P in the printing device 11, that is, an example of the width direction of the medium P, and is also an example of the width direction of the printing device 11. In addition, the X-axis direction is a horizontal direction along the installation surface G as a horizontal surface on which the printing device 11 is installed. In addition, when the operator is located on the front side of the printing device 11, the +X direction is the left side, and the -X direction is the right side. In addition, the front side of the printing device 11 in this embodiment is the side on which the heating unit 51 is installed.

[0026] The Y-axis direction is the depth direction of the printing device 11. In addition, the Y-axis direction is the horizontal direction along the installation surface G. The +Y direction in the Y-axis direction is the direction from the back side of the printing device 11 toward the front side of the printing device 11, and the -Y direction is the direction from the front side of the printing device 11 toward the back side of the printing device 11. In addition, in the following description, the +Y direction may be referred to as "front" and the -Y direction may be referred to as "rear".

[0027] The Z-axis direction is a normal direction with respect to the installation surface G, and is a height direction of the printing device 11. In the following description, the +Z direction may be referred to as "downward", and the -Z direction may be referred to as "upward".

[0028] like Figure 1 , Figure 2 As shown, the printing device 11 includes a printing unit 12. The printing unit 12 is configured to print an image on a medium P. Specifically, the printing unit 12 prints an image on the medium P by ejecting ink onto the medium P. The medium P also includes a fabric F of a pasting specification produced on an upper surface 23 described later. The printing unit 12 prints an image on the medium P transported in the +Y direction.

[0029] The printing unit 12 includes a head 13 . The head 13 includes a nozzle surface 15 in which one or more nozzles 14 are opened. The nozzle surface 15 faces the medium P. The head 13 ejects ink from the nozzles 14 .

[0030] The printing unit 12 has a carriage 16. The carriage 16 carries the head 13. In one example, the carriage 16 scans the medium P. That is, the carriage 16 moves in the X-axis direction. Specifically, the carriage 16 moves back and forth in the +X direction and the -X direction. Thus, the head 13 can eject ink across the width of the medium P. Therefore, the printing device 11 is a serial printer. The printing device 11 can also be a line printer that can eject ink all at once across the width of the medium P.

[0031] The printing unit 12 moves back and forth in the X-axis direction to move between the maintenance position P1 and the cleaning position P2. Figure 2 The two printing units 12 indicated by two-dot chain lines are located at the maintenance position P1 and the cleaning position P2, respectively.

[0032] At the maintenance position P1, the printing unit 12 is maintained by the maintenance unit 65. At the cleaning position P2, the printing unit 12 is cleaned by, for example, a user.

[0033] The printing device 11 includes an exterior member 22 and a frame 26 constituting a housing of a device body 20, and a leg 21. The leg 21 contacts a mounting surface G on which the printing device 11 is mounted. The exterior member 22 is mounted on the frame 26.

[0034] The exterior decoration member 22 has an upper surface 23, a front surface 24, and a back surface 25 that define the outer contours of the printing device 11 and the device body 20. The upper surface 23 is a surface facing the -Z direction, and defines a portion of the outer contours of the printing device 11 and the device body 20 in the -Z direction. The front surface 24 is a surface facing the +Y direction, and defines a portion of the outer contours of the printing device 11 and the device body 20 in the +Y direction. The back surface 25 is a surface facing the -Y direction, and defines the outer contours of the printing device 11 and the device body 20 in the -Y direction.

[0035] The frame 26 is made of, for example, a metal plate. The frame 26 supports various structures of the printing device 11. The frame 26 includes a main frame 27 and sub-frames 34, 35, and 36. By attaching the main frame 27 of the frame 26 to the leg 21, the device body 20 is fixed above the leg 21.

[0036] The main frame 27 has a plurality of surfaces. The main frame 27 has, for example, a front surface 28, a back surface 29, an upper surface 30, a lower surface 31, a right side surface 32, and a left side surface 33. The front surface 28 is a surface facing the front of the printing device 11. The back surface 29 is a surface facing the rear of the printing device 11. The upper surface 30 is a surface facing the upper side of the printing device 11. The lower surface 31 is a surface facing the lower side of the printing device 11. The right side surface 32 is a surface facing the -X direction. The left side surface 33 is a surface facing the +X direction.

[0037] The sub-frame 34 is attached to the main frame 27. In one example, the sub-frame 34 is attached to the upper surface 30 of the main frame 27. The sub-frame 34 supports, for example, an unwinding unit 71 described later.

[0038] The sub-frame 35 is mounted on the main frame 27. In one example, the sub-frame 35 is mounted on the right side 32 of the main frame 27. The sub-frame 35 is arranged in the -X direction of the main frame 27. The sub-frame 35 stores the waste liquid tank T1. The waste liquid tank T1 is connected to the maintenance unit 65. The waste liquid tank T1 stores the ink received by the maintenance unit 65. The waste liquid tank T1 can be replaced relative to the sub-frame 35.

[0039] The subframe 36 is mounted on the main frame 27. In one example, the subframe 36 is mounted on the left side 33 of the main frame 27. The subframe 36 is arranged in the +X direction of the main frame 27. The subframe 36 is a frame for ensuring the cleaning position P2. The upper side of the subframe 36 is the cleaning position P2.

[0040] The printing device 11 includes a reel 71. The reel 71 is configured to reel the medium P. Specifically, the reel 71 reels the medium P before printing. The medium P before printing includes a cloth F attached to an adhesive sheet AS. In addition, the reel 71 reels an adhesive sheet AS having a protective sheet SS provided on an adhesive layer described later. The reel 71 is provided in the upper surface 23 at a position closer to the -Y direction, that is, the back surface 25, than the center of the upper surface 23. The reel 71 is mounted on the sub-frame 34, for example.

[0041] The unwinding unit 71 includes unwinding units 71R and 71L spaced apart in the X-axis direction, and each of the unwinding units 71R and 71L includes a first shaft 72 and a shaft holding unit 75. The first shaft 72 of the unwinding unit 71R is inserted into and fixed to, for example, the core tube CT of the roll body R1 formed by winding the medium P from the -X direction of the core tube CT. The first shaft 72 of the unwinding unit 71L is inserted into and fixed to, for example, the core tube CT of the roll body R1 formed by winding the medium P from the +X direction of the core tube CT.

[0042] The shaft holding portion 75 of the unwinding portion 71R, 71L rotatably supports the pair of first shafts 72 fixed to the roll body R1, thereby supporting the roll body R1 rotatably around the axis along the X-axis direction. The medium P or the adhesive sheet AS is unwound from the roll body R1 by the rotation of the first shaft 72. In other words, the medium P or the adhesive sheet AS wound in a roll shape on the first shaft 72 is unwound by the rotation of the first shaft 72.

[0043] like Figures 1 to 4 As shown in FIG. 1 , the first shaft 72 includes an insertion portion 73, a flange 74, and a connecting hole 73h. The insertion portion 73 is a portion inserted into the core tube CT of the roll body R1 and has a cylindrical shape. The flange 74 is continuous in the extension direction of the insertion portion 73 and has a larger diameter than the insertion portion 73. The flange 74 is supported by the shaft holding portion 75 in a manner that allows rotation around the axis of the first shaft 72, so that the first shaft 72 is supported by the shaft holding portion 75 in a manner that allows rotation.

[0044] like Figure 4 As shown, an intermediate portion 73c having a smaller diameter than the outer shape of the flange 74 is provided at a position in the center of the flange 74 in the extension direction of the insertion portion 73. Figure 4 The first shaft 72 and the connecting shaft 91 are connected to each other and can rotate integrally by inserting the tip of the connecting shaft 91 of the drive mechanism 90 described later into the connecting hole 73h.

[0045] like Figure 3 , Figure 5 As shown in FIG. 1 , the shaft holding portion 75 includes a mounting portion 75m and a fixing portion 75f. The shaft holding portion 75 is provided on the upper surface 23 of the device body 20 by mounting the mounting portion 75m on the sub-frame 34. In addition, the shaft holding portion 75 can be mounted on the sub-frame 34 in such a manner that the interval between the pair of shaft holding portions 75 in the X-axis direction can be changed.

[0046] In this embodiment, the shaft holding portion 75 on the -X direction side of the pair of shaft holding portions 75 is fixed to Figure 2 In the position shown. Furthermore, by installing the shaft holding portion 75 on the +X direction side of the pair of shaft holding portions 75 so as to be movable in the X-axis direction, the spacing between the pair of shaft holding portions 75 in the X-axis direction is changed. In addition, the spacing between the flanges 74 of the pair of first shafts 72 in the X-axis direction is changed thereby. Furthermore, thereby, the unwinding portion 71 can support the core tube CT and the reel body R1 having different sizes in the X-axis direction between the flanges 74 of the pair of first shafts 72.

[0047] like Figure 5 As shown in FIG. 1 , a pair of force-applying parts 76 are provided on the shaft holding part 75. The force-applying part 76 is composed of a leaf spring 76s whose one end is fixed to the fixing part 75f of the shaft holding part 75, and a contact body 76p provided at the other end of the leaf spring 76s. The pair of contact bodies 76p are provided at positions contacting the peripheral surface of the intermediate part 73c of the first shaft 72.

[0048] When the contact body 76p contacts the peripheral surface of the middle portion 73c, the leaf spring 76s is elastically deformed, so that a force pressing the peripheral surface of the middle portion 73c acts toward the rotation center of the first shaft 72. This can suppress, for example, the situation in which the medium P is unwound excessively due to the first shaft 72 and the roll body R1 supported by the first shaft 72 rotating due to inertia force when the medium P is pulled out from the unwinding portion 71. In addition, tension acts on the medium P or the adhesive sheet AS pulled out from the unwinding portion 71.

[0049] like Figure 1As shown, the printing device 11 is provided with a conveying path TR for conveying the medium P unwound from the unwinding portion 71. The printing device 11 includes a medium support portion 43 constituting the conveying path TR. The medium support portion 43 supports the medium P. The medium support portion 43 supports the medium P to be printed by the printing portion 12 at a position opposite to the nozzle surface 15. Specifically, the medium support portion 43 supports a portion of the medium P to be printed by the printing portion 12. The medium support portion 43 is, for example, mounted on the upper surface 30 of the main frame 27. The medium support portion 43 is located above the main frame 27.

[0050] The printing device 11 includes a feed unit 41. The feed unit 41 is configured to transport the medium P. The feed unit 41 transports the medium P along the transport path TR. The feed unit 41 transports the medium P located on the medium support unit 43 in the +Y direction, which is the downstream of the transport direction. The feed unit 41 transports the medium P printed by the printing unit 12 to the lower side, which is the downstream of the transport direction. The feed unit 41 transports the medium P in such a manner that the medium P passes from above and in front of the main frame 27.

[0051] The feed unit 41 includes a conveying roller pair 42 and a conveying roller 45. The conveying roller pair 42 is driven by a conveying motor (not shown) to rotate. The conveying roller pair 42 rotates while sandwiching the medium P, thereby conveying the medium P toward the downstream in the conveying direction. The conveying roller 45 is rotatably provided on the conveying path TR. The conveying roller 45 guides the medium P along the conveying path TR. The conveying roller 45 rotates, so that the medium P is smoothly conveyed toward the downstream in the conveying direction.

[0052] The printing device 11 includes a winding unit 46. The winding unit 46 is configured to wind up the medium P. The winding unit 46 is installed, for example, at the end of the leg 21 in the +Y direction. The winding unit 46 includes a winding shaft 47. The winding shaft 47 is inserted into the core tube CT formed by winding the medium P and fixed. The winding shaft 47 is rotated by driving a winding motor (not shown). The core tube CT fixed to the winding shaft 47 is rotated, so that the medium P is wound on the core tube CT to form a roll body R2 in a roll shape.

[0053] The winding unit 46 winds up the printed medium P, for example. Also, for example, the winding unit 46 winds up the medium P heated by the heating unit 51 described later. Also, for example, the winding unit 46 winds up the fabric F attached to the adhesive sheet AS described later. The medium P is wound up by the winding unit 46, so that the medium P is transported downstream in the transport direction. In other words, the winding unit 46 is an example of the transport unit FP that transports the medium P.

[0054] The printing device 11 includes a heating unit 51. The heating unit 51 is configured to heat the medium P to which the ink is ejected. The heating unit 51 dries the medium P by heating the medium P. By drying the medium P, the image printed on the medium P is fixed. The heating unit 51 heats the medium P conveyed by the feeding unit 41. Specifically, the heating unit 51 heats the portion of the medium P that has been printed by the printing unit 12 and before being taken up by the take-up unit 46.

[0055] The heating unit 51 is mounted on the main frame 27. The heating unit 51 is located in front of the main frame 27. Specifically, the heating unit 51 is opposite to the front surface 28 of the main frame 27. The heating unit 51 heats the medium P passing between the heating unit 51 and the main frame 27. That is, in one example, the heating unit 51 heats a portion of the medium P that is conveyed downward. The heating unit 51 is provided so as to overlap with the exterior decoration member 22 when viewed from the vertical direction. In one example, a portion of the heating unit 51 overlaps with the exterior decoration member 22 when viewed from the vertical direction.

[0056] The heating unit 51 includes a heat source 52. The heat source 52 is configured to generate heat. The heat source 52 is opposite to the surface of the medium P on which the ink is ejected. Therefore, the heat source 52 heats the surface of the medium P on which the ink is ejected. In one example, the heat source 52 heats the medium P by radiant heat. The heat source 52 is, for example, an infrared heater. The heat source 52 irradiates infrared rays toward the medium P. The heat source 52 heats the medium P, thereby drying the medium P.

[0057] The heating unit 51 includes a blowing unit 53. The blowing unit 53 is, for example, a fan. The blowing unit 53 is configured to blow air toward the medium P. Specifically, the blowing unit 53 blows air toward the surface of the medium P on which the ink is ejected. Specifically, the blowing unit 53 blows air in a manner that the air flows downward along the medium P. Therefore, the air blown onto the medium P flows downward along the surface of the medium P on which the ink is ejected.

[0058] The heating unit 51 includes a housing 54 . The housing 54 accommodates the heat source 52 and the blowing unit 53 . The housing 54 is open toward the medium P. That is, the housing 54 is open toward the front surface 28 of the main frame 27 .

[0059] The housing 54 may also be provided with a circulation channel 55. The circulation channel 55 is a channel for circulating the air heated by the heat source 52. The circulation channel 55 extends to surround the heat source 52. The blowing section 53 is provided in the circulation channel 55. In the heating section 51, the air blown by the blowing section 53 circulates by flowing over the medium P and in the circulation channel 55. Specifically, the air is heated by the heat source 52. Figure 1 The circulation is performed as indicated by the arrows in the figure. As a result, the heating efficiency of the medium P is improved.

[0060] The printing device 11 includes a guide rod 61. The guide rod 61 is configured to guide the medium P toward the winding section 46. The guide rod 61 is located vertically below the heating section 51. The guide rod 61 has a peripheral surface 62. The peripheral surface 62 is a surface that comes into contact with the medium P. By winding the medium P on the peripheral surface 62, the guide rod 61 guides the medium P downward.

[0061] The medium P is wound around the guide rod 61 between the heating unit 51 and the winding unit 46. Therefore, the medium P heated by the heating unit 51 is wound around the guide rod 61. Therefore, the guide rod 61 contacts the portion of the medium P heated by the heating unit 51 and before being wound by the winding unit 46.

[0062] The guide rod 61 is configured to be rotatable. The guide rod 61 is configured to actively rotate relative to the medium P. The guide rod 61 may also be configured to passively rotate relative to the medium P. For example, the guide rod 61 may also rotate by friction with the medium P as the medium P is conveyed. In other words, the guide rod 61 may also rotate by friction with the medium P as the medium P is taken up by the take-up unit 46.

[0063] The printing device 11 includes a driving unit 63 (not shown). The guide rod 61 is rotated by driving the driving unit 63. The driving unit 63 is, for example, a motor. The driving unit 63 is attached to the main frame 27, for example.

[0064] The driving unit 63 rotates the guide rod 61 at a rotation speed such that the moving speed of the peripheral surface 62 matches the conveying speed of the medium P achieved by the feeding unit 41. This reduces the friction between the medium P and the guide rod 61. Alternatively, the driving unit 63 may rotate the guide rod 61 such that the moving speed of the peripheral surface 62 is faster than the conveying speed of the medium P achieved by the feeding unit 41.

[0065] The printing device 11 includes a heat insulating member 64. The heat insulating member 64 is configured to block heat generated by the heating unit 51. Specifically, the heat insulating member 64 blocks heat from the heating unit 51 to the main frame 27. The heat insulating member 64 is located between the heating unit 51 and the main frame 27. The heat insulating member 64 is mounted on the front surface 28 of the main frame 27. The heat insulating member 64 is provided along the front surface 28. The heat insulating member 64 is opposite to the heating unit 51. The medium P passes between the heat insulating member 64 and the heating unit 51.

[0066] like Figure 2 As shown, the printing device 11 includes a maintenance unit 65. The maintenance unit 65 performs maintenance on the printing unit 12 located at the maintenance position P1. In one example, the maintenance unit 65 performs maintenance on the printing unit 12 by receiving ink generated by flushing, cleaning, etc. from the printing unit 12.

[0067] Flushing is the action of appropriately ejecting ink from the nozzle 14. By performing flushing, the possibility of clogging of the nozzle 14 is reduced. Cleaning is the action of discharging ink from the nozzle 14. By performing cleaning, foreign matter is discharged from the nozzle 14 together with the ink. The maintenance unit 65 discharges the ink from the nozzle 14 by, for example, performing suction while in contact with the head 13. The ink received by the maintenance unit 65 flows to the waste liquid tank T1.

[0068] like Figure 1 As shown, the printing device 11 includes a control unit 66. The control unit 66 performs overall control of the printing device 11. That is, the control unit 66 controls the driving of the unwinding unit 71, the feeding unit 41, the printing unit 12, the heating unit 51, the guide rod 61, the winding unit 46, and the maintenance unit 65.

[0069] The control unit 66 is composed of one or more processors that execute various processes according to a computer program. The control unit 66 is composed of one or more dedicated hardware circuits such as a dedicated integrated circuit that executes at least a part of the various processes. The control unit 66 can also be composed of a circuit including a combination of a processor and a hardware circuit. The processor includes a CPU, and a memory such as a RAM and a ROM. The memory stores program codes or instructions that are configured in a manner that enables the CPU to execute a process. The memory, that is, the computer-readable medium, includes all readable media that can be accessed by a general-purpose or dedicated computer.

[0070] In addition, if Figure 6 , Figure 7As shown, the printing device 11 includes a guide portion 81. The guide portion 81 is mounted on the device body 20 when the fabric F is attached to the adhesive sheet AS. The guide portion 81 is provided in a detachable manner relative to the device body 20. The guide portion 81 supports the second shaft 82 in a manner that allows rotation around the axis along the X-axis direction. The guide portion 81 is provided in the upper surface 23 at a position closer to the -Y direction, that is, the back surface 25, than the center of the upper surface 23. The guide portion 81 includes a loading portion 84, a leg portion 85, and a driving mechanism 90.

[0071] The -Z direction surface, i.e., the upper surface, of the placement portion 84 extends in the X-axis direction along the XY plane. When the guide portion 81 is installed in the device body 20, the placement portion 84 is located vertically above the first shaft 72 and the second shaft 82. The upper surface of the placement portion 84 is configured so that the fabric F can be placed when the fabric F is attached to the adhesive sheet AS (see FIG. Fig.10 ).

[0072] When the fabric F is attached to the adhesive sheet AS, the fabric F placed on the placement portion 84 passes through the upper position Pu and moves toward the region of the upper surface 23 in the +Y direction of the placement portion 84. The upper position Pu is a position vertically above the first axis 72 and the second axis 82. The placement portion 84 is an example of a contact portion CP that contacts the fabric F and causes the fabric F to pass from the upper position Pu.

[0073] A position guide 99 for guiding the position of the fabric F in the X-axis direction is provided on the upper surface of the placement portion 84. In other words, the guide portion 81 has the position guide 99 at the upper position Pu. The X-axis direction is an example of the width direction of the fabric F that intersects the direction of the fabric F toward the upper surface 23. The position guide 99 is composed of a position guide 99R for guiding the position of the end of the fabric F in the -X direction and a position guide 99L for guiding the position of the end of the fabric F in the +X direction.

[0074] The position guide 99R of this embodiment is a protrusion that can adjust the position of the side surface in the +X direction in accordance with the position of the flange 74 of the unwinding section 71R in the X-axis direction. Thus, the position guide 99R restricts the position of the end of the fabric F in the -X direction to the same position as the end of the roll body R1 supported by the unwinding section 71 in the -X direction.

[0075] In addition, the position guide 99L of this embodiment is a protrusion that can adjust the position of the side surface in the -X direction in accordance with the position of the flange 74 of the unwinding section 71L in the X-axis direction. Thus, the position guide 99L can limit the position of the end of the cloth F in the +X direction to the same position as the end of the roll body R1 supported by the unwinding section 71 in the +X direction.

[0076] In addition, the position guide 99 may be a mark such as a character mark provided on the upper surface of the placement portion 84 so as to serve as a standard for the placement position of the fabric F when the user places the fabric F on the placement portion 84. In this case, a plurality of marks provided on the upper surface of the placement portion 84 may be provided corresponding to the size of the roll body R1 supported by the unwinding portion 71 in the X-axis direction.

[0077] The foot portion 85 includes a foot portion 85R extending vertically downward from the end portion of the mounting portion 84 in the -X direction, and a foot portion 85L extending vertically downward from the end portion of the mounting portion 84 in the +X direction. The foot portion 85 supports the second shaft 82 at a position vertically below the mounting portion 84 so as to be rotatable around the axis of the second shaft 82 along the X-axis direction. The foot portion 85R supports the vicinity of the end portion in the -X direction of the second shaft 82. The foot portion 85L supports the end portion in the +X direction of the second shaft 82.

[0078] The leg portion 85 is provided with an engaging portion 89 that can engage with the engaged portion 79 provided on the device body 20. The engaged portion 79 includes engaged portions 79R and 79L. The engaged portion 79R is provided on the upper surface 23 side of the device body 20 and is located at a position on the -X direction side of the unwinding portion 71R. The engaged portion 79L is provided on the upper surface 23 side of the device body 20 and is located at a position on the +X direction side of the unwinding portion 71L. The engaged portions 79R and 79L are recessed and open toward the -Z direction.

[0079] The engaging portion 89 includes engaging portions 89R and 89L. The engaging portion 89R is provided at the end of the leg 85R in the +Z direction. The engaging portion 89R is a protrusion that can engage with the engaged portion 79R and extends from the end of the leg 85R in the +Z direction. The engaging portion 89L is provided at the end of the leg 85L in the +Z direction. The engaging portion 89L is a protrusion that can engage with the engaged portion 79L and extends from the end of the leg 85L in the +Z direction.

[0080] The engaging portions 89R and 89L are engaged with the engaged portions 79R and 79L, so that the guide portion 81 is mounted on the device body 20. The engaged portions 79R and 79L of the present embodiment are provided on the sub-frame 34, for example.

[0081] The second shaft 82 is lateral to the leg portions 85R and 85L in the −X direction. Figure 6 The method of installing the support position shown is set. In the process of installing from the -X direction lateral support position of the leg 85R, the core tube CT is inserted and fixed on the second shaft 82. And, for example, when the fabric F is attached to the adhesive sheet AS, the protective sheet SS peeled off from the adhesive sheet AS unwound from the first shaft 72 of the unwinding unit 71 is wound on the core tube CT fixed on the second shaft 82.

[0082] The driving mechanism 90 rotates the second shaft 82. The second shaft 82 rotates, so that, for example, the protective sheet SS peeled off from the adhesive sheet AS unwound from the first shaft 72 of the unwinding section 71 is wound onto the core tube CT fixed to the second shaft 82. The driving mechanism 90 includes a connecting shaft 91, a first gear 92, a second gear 93, and a torque limiter 94. The second gear 93 is provided at the end of the second shaft 82 in the -X direction. The torque limiter 94 is provided on the second shaft 82 at a position adjacent to the second gear 93 in the +X direction.

[0083] The connecting shaft 91 is supported at the foot portion 85R of the guide portion 81 so as to be rotatable about the axis along the X-axis direction. Figure 6 The tip of the +X direction end portion can be inserted into the connecting hole 73h of the first shaft 72 (see Figure 4 ) and is supported on the leg 85R.

[0084] The connecting shaft 91 is movable to a connecting position (see FIG. 1 ) where the connecting shaft 91 is connected to the first shaft 72 by inserting the top end thereof into the connecting hole 73h of the first shaft 72. Figure 6 ) is supported on the leg 85R. In addition, the connecting shaft 91 is supported on the leg 85R in a manner that it can move to a separation position (not shown) where the connection with the first shaft 72 is released and is located at a separation position in the -X direction of the connection position.

[0085] The first gear 92 is provided on the connecting shaft 91. Figure 6 The first gear 92 is provided with a gripping portion 95 for a user to grip when the connecting shaft 91 is moved to the connecting position and the disconnecting position. When the connecting shaft 91 is at the connecting position, the first gear 92 meshes with the second gear 93 provided at the end of the second shaft 82 in the -X direction. When the connecting shaft 91 is at the disconnecting position, the first gear 92 is located on the -X direction side of the second gear 93 and is separated from the second gear 93.

[0086] When the connecting shaft 91 is in the connecting position, Figure 7 As shown by the solid arrow in FIG. 1 , the first shaft 72 of the unwinding portion 71 rotates counterclockwise when viewed from the -X direction side of the first shaft 72. In this case, the connecting shaft 91 and the first gear 92 are as shown in FIG. Figure 7 As shown by the solid arrow in FIG. 1 , the first gear 92 rotates counterclockwise when viewed from the -X direction side. As a result, the second gear 93 and the second shaft 82 are as shown in FIG. Figure 7 As shown by the dotted arrow in FIG. 8 , the second shaft 82 rotates clockwise when viewed from the −X direction side. In other words, the first gear 92 and the second gear 93 are meshed with each other, so that the first shaft 72 and the second shaft 82 rotate in conjunction with each other.

[0087] For example, the user performs a process of attaching the fabric F to the adhesive sheet AS. In this case, first, the user installs the guide portion 81 on the device body 20. Then, when the connecting shaft 91 is in the separated position, as shown in FIG. Figure 8 As shown, the user fixes the core tube CT wound with the adhesive sheet AS on the first shaft 72 of the unwinding section 71. The adhesive sheet AS and the protective sheet SS disposed on the adhesive layer of the adhesive sheet AS are wound on the core tube CT in a direction in which the adhesive layer becomes the outer side of the base material of the adhesive sheet AS.

[0088] Then, the user fixes the core tube CT wound with the adhesive sheet AS to the first shaft 72. At this time, when the adhesive sheet AS is pulled out from the unwinding portion 71 in the +Y direction, the core tube CT is fixed to the first shaft 72 in a direction in which the first shaft 72 rotates counterclockwise when the first shaft 72 is viewed from the -X direction side. Then, the user fixes the end of the protective sheet SS peeled off from the adhesive sheet AS to the core tube CT fixed to the second shaft 82. Then, the user moves the connecting shaft 91 to the connecting position.

[0089] Moreover, if Fig. 9 As shown in FIG. 1 , when the user pulls out the adhesive sheet AS from the unwinding portion 71 in the +Y direction, the first shaft 72 rotates counterclockwise when viewed from the -X direction side of the first shaft 72. As a result, the connecting shaft 91, the first gear 92, and the second gear 93 constituting the driving mechanism 90 rotate, so that the second shaft 82 rotates clockwise when viewed from the -X direction side of the second shaft 82. Furthermore, as the second shaft 82 rotates, the protective sheet SS peeled off from the adhesive sheet AS is wound onto the core tube CT fixed to the second shaft 82.

[0090] When the adhesive sheet AS is unwound from the unwinding section 71, the protective sheet SS is peeled off from the adhesive sheet AS. At this time, there is a case where the amount of the protective sheet SS collected and wound up by the second shaft 82 rotating one turn is less than the amount of the protective sheet SS peeled off from the adhesive sheet AS by the first shaft 72 rotating one turn. In this case, the protective sheet SS peeled off from the adhesive sheet AS may be loosened and retained between the adhesive sheet AS unwound from the unwinding section 71 and the protective sheet SS wound on the core tube CT of the second shaft 82.

[0091] In contrast, in the present embodiment, the number of teeth of the first gear 92 is set to be greater than the number of teeth of the second gear 93. Thus, the amount of the protective sheet SS collected by the second shaft 82 rotating one turn is unlikely to decrease relative to the amount of the protective sheet SS peeled off from the unwound adhesive sheet AS by the first shaft 72 rotating one turn.

[0092] In addition, there is a case where the amount of the protective sheet SS collected and wound up by the second shaft 82 rotating one turn becomes larger than the amount of the protective sheet SS peeled off from the adhesive sheet AS by the first shaft 72 rotating one turn. In this case, the protective sheet SS peeled off from the adhesive sheet AS is stretched between the adhesive sheet AS wound on the core tube CT of the first shaft 72 and the protective sheet SS wound on the core tube CT of the second shaft 82. In addition, there is a possibility that a larger tension than expected acts on the protective sheet SS peeled off from the adhesive sheet AS.

[0093] In contrast, the drive mechanism 90 of the present embodiment is provided with a torque limiter 94 that limits the rotational torque transmitted from the second gear 93 to the second shaft 82 as the second gear 93 rotates. The torque limiter 94 is provided between the second gear 93 and the second shaft 82, and connects the second gear 93 and the second shaft 82. When the rotational torque transmitted from the second gear 93 to the torque limiter 94 as the second gear 93 rotates becomes greater than a set value, the torque limiter 94 releases the connection between the second gear 93 and the second shaft 82.

[0094] Thus, the rotation torque transmitted from the second gear 93 to the second shaft 82 along with the rotation of the second gear 93 is adjusted to be smaller than the set value. In addition, by applying tension to the protective sheet SS peeled off from the adhesive sheet AS, it is possible to suppress damage to any of the protective sheet SS, the guide portion 81, and the unwinding portion 71. As the torque limiter 94, a mechanical torque limiter such as a friction type, a safety pin type, a ball type, a magnet type, or a tolerance ring as a sliding clutch can be used.

[0095] like Fig.10 As shown in FIG. 1 , the adhesive sheet AS pulled out from the unwinding section 71 is supported on the region of the upper surface 23 in the +Y direction that becomes the placement section 84. The upper surface 23 is an example of a support section SP that supports the adhesive sheet AS from which the adhesive layer is exposed by peeling off the protective sheet SS. Then, the user places the fabric F on the adhesive sheet AS supported on the upper surface 23 via the upper position Pu.

[0096] Then, the user uses a pressing member HT, etc., to press the fabric F from the -Z direction side of the fabric F toward the adhesive sheet AS supported on the upper surface 23, as indicated by the white hollow arrow mark. Thus, a fabric F having a pasting specification in which the fabric F is pasted on the adhesive sheet AS is produced.

[0097] In addition, in the present embodiment, in the Z-axis direction, the second shaft 82 is located between the first shaft 72 of the unwinding section 71 and the mounting section 84. For example, in the Y-axis direction, the region between the region where the fabric F is mounted on the adhesive sheet AS and the region where the fabric F is mounted on the mounting section 84 in the upper surface 23 is set as the pull-out region. In this case, in the pull-out region, the protective sheet SS peeled off from the adhesive sheet AS is located between the fabric F and the adhesive sheet AS. Therefore, it is possible to suppress the fabric F from coming into contact with the adhesive sheet AS whose adhesive layer is exposed in the pull-out region.

[0098] When printing is performed on the fabric F of the pasting specification, the user removes the guide portion 81 from the device body 20. In addition, the user removes the core tube CT wound with the adhesive sheet AS from the unwinding portion 71. Then, the user mounts the core tube CT wound with the fabric F of the pasting specification on the first shaft 72 of the unwinding portion 71.

[0099] Then, the user operates the instruction unit (not shown) to instruct the printing device 11 to print on the medium P. Thus, the control unit 66 controls the driving of the feeding unit 41, the printing unit 12, the heating unit 51, the guide rod 61, the winding unit 46, etc., so that the printing unit 12 performs printing on the medium P in the bonded state.

[0100] In addition, in the printing device 11 of this embodiment, when the produced fabric F of the pasting specification is wound on the core tube CT, the winding unit 46 can be used. In this case, by winding the fabric F of the pasting specification on the core tube CT fixed to the winding shaft 47, the core tube CT on which the fabric F of the pasting specification is wound is produced.

[0101] In this case, the fabric F of the pasting specification is rolled up by the roll-up unit 46, and the fabric F of the pasting specification is transported from the upper surface 23 toward the roll-up unit 46. Therefore, the roll-up unit 46 is an example of a transport unit FP that transports the fabric F of the pasting specification.

[0102] As described above, according to the printing device 11 according to the first embodiment, the following effects can be obtained.

[0103] The printing device 11 includes a first shaft 72 on which an adhesive sheet AS is wound. The adhesive sheet AS includes a base material and an adhesive layer formed on the base material, and a protective sheet SS is provided on the adhesive layer. In addition, the printing device 11 includes a second shaft 82 on which a protective sheet SS peeled off from the adhesive sheet AS unwound from the first shaft 72 is wound. In addition, the printing device 11 includes a driving mechanism 90 that rotates the second shaft 82. In addition, the printing device 11 includes an upper surface 23 that supports the adhesive sheet AS from which the protective sheet SS is peeled off and the adhesive layer is exposed. In addition, the printing device 11 includes a guide portion 81 that allows the cloth F to pass from an upper position Pu that is vertically above the first shaft 72 and the second shaft 82, and guides the cloth F toward the upper surface 23. Furthermore, the printing device 11 includes a printing unit 12 that can print on the upper surface 23 of the fabric F attached to the adhesive sheet AS.

[0104] Accordingly, since the protective sheet SS peeled off from the adhesive sheet AS is collected on the second shaft 82, it is possible to reduce the reduction in the user's workability in the process of sticking the fabric F on the adhesive sheet AS. In addition, since the fabric F is difficult to come into contact with the adhesive sheet AS with the adhesive layer exposed due to its own weight, it is possible to suppress the reduction in the user's workability in the process of sticking the fabric F on the adhesive sheet AS.

[0105] The driving mechanism 90 includes a first gear 92 and a second gear 93, wherein the first gear 92 rotates together with the first shaft 72, and the second gear 93 rotates together with the second shaft 82. Furthermore, the first shaft 72 and the second shaft 82 rotate in conjunction with each other by meshing the first gear 92 with the second gear 93. Accordingly, the driving mechanism 90 that rotates the second shaft 82 can be realized by utilizing the rotation of the first shaft 72.

[0106] The number of teeth of the first gear 92 is greater than the number of teeth of the second gear 93, and the drive mechanism 90 has a torque limiter 94 that limits the rotational torque transmitted from the second gear 93 to the second shaft 82 as the second gear 93 rotates. Thus, the protective sheet SS peeled off from the adhesive sheet AS can be wound onto the second shaft 82 to a good extent.

[0107] The printing device 11 includes a force applying portion 76 that contacts the first shaft 72 to apply force toward the rotation center of the first shaft 72. This can suppress the adhesive sheet AS from being loosened when the adhesive sheet AS is excessively pulled from the first shaft 72.

[0108] The printing device 11 includes a winding unit 46 that conveys the fabric F attached to the adhesive sheet AS. This can save the user from having to move the fabric F attached to the adhesive sheet AS.

[0109] The guide portion 81 rotatably supports the second shaft 82, has a driving mechanism 90, and is detachably provided on the device body 20 having the upper surface 23. Accordingly, when the process of attaching the fabric F to the adhesive sheet AS is not performed, the guide portion 81 can be removed from the device body 20. Therefore, when the process of attaching the fabric F to the adhesive sheet AS is not performed, the user can effectively and flexibly use the upper surface 23.

[0110] The guide portion 81 includes a loading portion 84 and a leg portion 85, wherein the loading portion 84 makes contact with the fabric F so that the fabric F passes from the upper position Pu, and the leg portion 85 extends vertically downward from the loading portion 84 and rotatably supports the second shaft 82. In addition, the leg portion 85 includes an engaging portion 89 that can engage with the engaged portion 79 provided on the upper surface 23. Accordingly, the guide portion 81 can be easily attached to and detached from the upper surface 23 of the device body 20.

[0111] The guide portion 81 has a position guide portion 99 at the upper position Pu, and the position guide portion 99 guides the position of the fabric F in the X-axis direction. This allows the fabric F to be attached to the adhesive sheet AS with high positional accuracy.

[0112] 2. Implementation Method 2

[0113] like Fig.11As shown, the printing device 11 according to the second embodiment further includes a supply unit 48 on the foot unit 21 in the first embodiment, and the supply unit 48 can unwind the fabric F. In addition, the end portion in the +Y direction of the upper surface 23 in the printing device 11 according to the second embodiment, that is, the end portion 23e is located closer to the +Y direction side than the front side which is the outer surface in the +Y direction of the heating unit 51.

[0114] The other configurations of the printing device 11 according to the second embodiment are the same as those of the printing device 11 according to the first embodiment. The same reference numerals are used for the same configurations as those in the first embodiment, and duplicate descriptions are omitted.

[0115] In the present embodiment, the supply unit 48 is installed at a position on the -Y direction side relative to the center of the leg 21. The supply unit 48 is provided at a position in the +Z direction relative to the placement unit 84 of the guide unit 81 installed on the device body 20. In addition, the supply unit 48 is provided at a position in the +Z direction relative to the upper surface 23. In addition, the supply unit 48 is provided at a position in the -Y direction relative to the end 23e which is the end of the upper surface 23 in the +Y direction.

[0116] The supply unit 48 has the same structure as the unwinding unit 71. Therefore, the first shaft 72 of the supply unit 48 is inserted and fixed in the core tube CT of the roll body R3 formed by winding the fabric F. And, the first shaft 72 of the supply unit 48 rotates, so that the fabric F is unwound from the supply unit 48. In this case, a pair of force applying parts 76 are provided on the shaft holding part 75 of the supply unit 48. Therefore, when the fabric F is pulled out from the supply unit 48, tension acts on the fabric F.

[0117] When fabric F of a bonding specification in which fabric F is bonded to adhesive sheet AS is produced, the user places fabric F on adhesive sheet AS supported by upper surface 23 via upper position Pu, similarly to Embodiment 1. Then, the user pulls adhesive sheet AS on which fabric F is bonded in the +Z direction relative to upper surface 23. At this time, since tension acts on fabric F, fabric F is pressed against adhesive sheet AS passing through end 23e of upper surface 23. As a result, fabric F is bonded to adhesive sheet AS.

[0118] Furthermore, when the fabric F of the pasting specification in which the fabric is pasted on the adhesive sheet AS is wound on the core tube CT, the fabric F of the pasting specification may be wound on the core tube CT fixed to the winding shaft 47 of the winding unit 46. Furthermore, by causing the winding unit 46 to wind the fabric F of the pasting specification on the winding shaft 47, the fabric F is pressed against the adhesive sheet AS passing through the end 23e of the upper surface 23. As a result, the fabric F is pasted on the adhesive sheet AS.

[0119] In this case, the winding unit 46 can be regarded as an example of a pressing unit PP that presses the fabric F against the adhesive sheet AS supported by the end portion 23e of the surface 23. As described above, according to the printing device 11 according to the second embodiment, the following effects can be obtained.

[0120] The printing device 11 includes a winding unit 46 that presses the fabric F onto the adhesive sheet AS supported by the upper surface 23. This can omit the user's operation of pressing the fabric F onto the adhesive sheet AS.

[0121] 3. Implementation Method 3

[0122] like Fig.12 As shown, the printing device 11 involved in the third embodiment is also provided with a supply unit 48 capable of unwinding the fabric F, similar to the second embodiment. In addition, the printing device 11 involved in the third embodiment is provided with a guide roller 98 instead of the loading unit 84 of the guide unit 81 in the first embodiment. In addition, the printing device 11 involved in the third embodiment is provided with a pressing mechanism 86 and a collecting roller 83 on the guide unit 81 in the first embodiment, wherein the pressing mechanism 86 has a pressing roller 87 and a moving unit 88. In addition, the printing device 11 involved in the third embodiment is provided with an introduction path IR including an introduction port 37 on the device body 20 in the first embodiment.

[0123] The other configurations of the printing device 11 according to the third embodiment are the same as those of the printing device 11 according to the first embodiment. The same reference numerals are used for the same configurations as those in the first and second embodiments, and duplicate descriptions are omitted.

[0124] The guide roller 98 is provided at a position between the legs 85R and 85L in the X-axis direction. The guide roller 98 is a cylindrical roller supported by the legs 85R and 85L in a manner that allows rotation around the axis center along the X-axis. The circumferential surface of the guide roller 98 extends in the X-axis direction. When the guide portion 81 is mounted on the device body 20, the guide roller 98 is located in the -Z direction of the first shaft 72 and the second shaft 82. The circumferential surface of the guide roller 98 is provided so as to be able to guide the fabric F by contacting the fabric F when the fabric F is attached to the adhesive sheet AS.

[0125] When the fabric F is attached to the adhesive sheet AS, the fabric F guided by the guide roller 98 passes from the upper position Pu and moves toward the area of ​​the upper surface 23 in the +Y direction of the guide roller 98. The guide roller 98 is an example of a contact portion CP that contacts the fabric F and allows the fabric F to pass from the upper position Pu.

[0126] The pressing roller 87 is provided at a position between the legs 85R and 85L in the X-axis direction. The pressing roller 87 is a cylindrical roller supported by the moving part 88 so as to be rotatable about the axis center along the X-axis. The moving part 88 is provided on the legs 85R and 85L so as to be able to move the pressing roller 87 to the pressing position and the standby position.

[0127] The pressing position is a position where the pressing roller 87 can press the fabric F against the adhesive sheet AS supported by the upper surface 23 in the region of the upper surface 23 in the +Y direction of the guide roller 98. Therefore, the pressing roller 87 is an example of a pressing portion PP that presses the fabric F against the adhesive sheet AS supported by the upper surface 23. The standby position is a position separated from the pressing position in the -Z direction, and a gap is formed between the adhesive sheet AS supported by the upper surface 23 and the pressing roller 87.

[0128] The movement of the pressing roller 87 to the pressing position and the standby position may be performed by manual operation of the user or by driving a pressing motor provided in the pressing mechanism 86. When the pressing mechanism 86 includes a pressing motor, the driving of the pressing motor is controlled by the control unit 66.

[0129] The collecting roller 83 is provided at a position between the legs 85R and 85L in the X-axis direction. The collecting roller 83 is a cylindrical roller supported by the legs 85R and 85L in a manner that allows rotation about the axis center along the X-axis. The collecting roller 83 extends in the X-axis direction. When the guide portion 81 is mounted on the device body 20, the collecting roller 83 is located between the first shaft 72 and the pressing roller 87 in the Y-axis direction. In addition, the collecting roller 83 is located between the second shaft 82 and the pressing roller 87 in the Z-axis direction.

[0130] In the process of attaching the fabric F to the adhesive sheet AS, the protective sheet SS peeled off from the adhesive sheet AS is wound on the collecting roller 83 and then wound on the second shaft 82. As a result, the protective sheet SS is stably wound on the second shaft 82. In addition, in this embodiment, as in the first embodiment, the protective sheet SS peeled off from the adhesive sheet AS is also located between the fabric F and the adhesive sheet AS in the pull-out region. In addition, the collecting roller 83 is located near the pressing roller 87 between the first shaft 72 and the pressing roller 87. Therefore, in the pull-out region, the fabric F is further prevented from coming into contact with the adhesive sheet AS whose adhesive layer is exposed.

[0131] The introduction path IR is provided on the device body 20 in such a manner that the medium P can be introduced into the middle of the transport path TR. For example, the introduction path IR introduces the fabric F of the pasting specification produced on the upper surface 23 into the transport path TR at a position upstream in the transport direction relative to the medium support portion 43 through the introduction port 37. The introduction port 37 is provided on the front surface 24 of the device body 20 and opens toward the +Y direction.

[0132] A pair of conveying rollers 42 is provided on the introduction path IR, and the pair of conveying rollers 42 conveys the fabric F of the pasting specification that enters the device body 20 through the introduction port 37 to the downstream of the conveying direction indicated by the arrow mark. The pair of conveying rollers 42 provided on the introduction path IR is an example of a conveying unit FP that conveys the fabric F of the pasting specification.

[0133] According to the printing device 11 of the present embodiment, by inserting the fabric F of the pasting specification produced on the upper surface 23 into the introduction port 37 , the printing by the printing unit 12 can be performed on the fabric F of the pasting specification.

[0134] First, when making a fabric F of a pasted specification in which the fabric F is pasted on the adhesive sheet AS, the user places the fabric F on the adhesive sheet AS supported by the upper surface 23 via the upper position Pu, as in Embodiment 1. At this time, the fabric F unwound from the supply unit 48 passes through the -Z direction side of the guide roller 98 and the +Z direction side of the pressing roller 87 in the standby position and is placed on the adhesive sheet AS supported by the upper surface 23.

[0135] Furthermore, by placing the pressing roller 87 at the pressing position, the fabric F is pressed against the adhesive sheet AS supported by the upper surface 23. In this state, the fabric F pressed against the adhesive sheet AS and the adhesive sheet AS are pulled out in the +Y direction, thereby producing a fabric F having a pasted specification in which the fabric F is pasted on the adhesive sheet AS.

[0136] When printing is performed on the fabric F of the pasting specification, the user inserts the top end of the fabric F of the pasting specification formed by pasting the fabric F on the adhesive sheet AS into the introduction port 37. Then, the user operates the instruction unit to instruct the printing device 11 to print on the fabric F of the pasting specification. Thus, the control unit 66 controls the driving of the conveying roller pair 42 of the introduction path IR to convey the fabric F of the pasting specification via the introduction path IR toward the conveying path TR that is downstream in the conveying direction.

[0137] Furthermore, the control unit 66 controls the driving of the feed unit 41, the printing unit 12, the heating unit 51, the guide rod 61, the winding unit 46, etc. of the transport path TR, so that the printing unit 12 performs printing on the medium P in the bonded state. In addition, through the above-mentioned control of the control unit 66, the medium P in the bonded state printed by the printing unit 12 is wound onto the core tube CT fixed to the winding shaft 47.

[0138] As described above, according to the printing device 11 according to the third embodiment, the following effects can be obtained.

[0139] The printing device 11 includes a pressing roller 87 for pressing the fabric F against the adhesive sheet AS supported by the upper surface 23. This can omit the user's work of pressing the fabric F against the adhesive sheet AS.

[0140] The printing device 11 includes a pair of conveying rollers 42 for conveying the fabric F attached to the adhesive sheet AS. This can save the user from having to move the fabric F attached to the adhesive sheet AS.

[0141] The guide portion 81 includes a guide roller 98 and a foot portion 85, wherein the guide roller 98 makes contact with the fabric F so that the fabric F passes from the upper position Pu, and the foot portion 85 extends vertically downward from the guide roller 98 and rotatably supports the second shaft 82. In addition, the foot portion 85 includes an engaging portion 89 that can engage with the engaged portion 79 provided on the upper surface 23. Accordingly, the guide portion 81 can be easily attached and detached relative to the upper surface 23 of the device body 20.

[0142] Although the printing device 11 involved in the above-mentioned embodiment of the present disclosure is a printing device based on the structure described above, it is of course possible to implement changes or omissions of some structures within the scope of the present disclosure. In addition, the above-mentioned embodiment and other embodiments described below can be combined with each other within the scope of technical non-contradiction. Other embodiments are described below.

[0143] In the above embodiment, when the process of attaching the fabric F to the adhesive sheet AS is performed, the core tube CT on which the adhesive sheet AS is wound may be fixed to the second shaft 82. In this case, the core tube CT is wound with the adhesive sheet AS and the protective sheet SS provided on the adhesive layer of the adhesive sheet AS in a direction in which the adhesive layer becomes the inner side of the base material of the adhesive sheet AS. In this case, when the adhesive sheet AS is pulled out from the second shaft 82 in the +Y direction, the core tube CT on which the adhesive sheet AS is wound is fixed to the second shaft 82 in a direction in which the second shaft 82 rotates clockwise when viewed from the -X direction side of the second shaft 82.

[0144] Furthermore, the end of the protective sheet SS peeled off from the adhesive sheet AS is fixed to the core tube CT fixed to the first shaft 72 of the unwinding section 71 via the -Z direction and -Y direction of the second shaft 82. Furthermore, the connecting shaft 91 is moved to the connecting position. Furthermore, when the adhesive sheet AS is pulled out from the second shaft 82 in the +Y direction, the second shaft 82 rotates clockwise when viewed from the -X direction side of the second shaft 82. Thus, by rotating the second gear 93, the first gear 92, and the connecting shaft 91 constituting the driving mechanism 90, the first shaft 72 rotates counterclockwise when viewed from the -X direction side of the first shaft 72. Furthermore, by rotating the first shaft 72, the protective sheet SS peeled off from the adhesive sheet AS is wound onto the core tube CT fixed to the first shaft 72.

[0145] In the above embodiment, the first shaft 72 and the second shaft 82 may be rotated in conjunction with each other without meshing the first gear 92 as the driving gear of the driving mechanism 90 with the second gear 93 as the driven gear. For example, the driving mechanism 90 may include an intermediate gear inserted between the first gear 92 and the second gear 93 to transmit the rotation of the first gear 92 to the second gear 93. As in the above embodiment, when the rotation direction of the second gear 93 is set to be opposite to the rotation direction of the first gear 92, the driving mechanism 90 may include an even number of intermediate gears.

[0146] In the case where the rotation direction of the second gear 93 is set to be the same as the rotation direction of the first gear 92, the drive mechanism 90 may also have an odd number of intermediate gears. In addition, for example, the drive mechanism 90 may also have a first gear 92, a second gear 93, and a chain, wherein the first gear 92 rotates together with the first shaft 72, the second gear 93 rotates together with the second shaft 82, and the chain is wound around the first gear 92 and the second gear 93. Accordingly, the adhesive sheet AS and the protective sheet SS provided on the adhesive layer of the adhesive sheet AS, which is wound around the core tube CT in a direction where the adhesive layer becomes the inner side of the base material, can be used to produce a fabric F of an adhesive specification.

[0147] In this case, when the adhesive sheet AS is pulled out from the unwinding section 71 in the +Y direction, the core tube CT wound with the adhesive sheet AS is fixed to the first shaft 72 in a direction in which the first shaft 72 rotates clockwise when viewed from the -X direction side of the first shaft 72. Moreover, the end of the protective sheet SS peeled off from the adhesive sheet AS is fixed to the core tube CT fixed to the second shaft 82. And the connecting shaft 91 is moved to the connecting position. Moreover, when the adhesive sheet AS is pulled out from the unwinding section 71 in the +Y direction, the first shaft 72 rotates clockwise when viewed from the -X direction side of the first shaft 72. Thus, by rotating the connecting shaft 91, the first gear 92, and the second gear 93 constituting the driving mechanism 90, the second shaft 82 rotates clockwise when viewed from the -X direction side of the second shaft 82. Then, by rotating the second shaft 82 , the protection sheet SS peeled off from the adhesive sheet AS is wound onto the core tube CT fixed to the second shaft 82 .

[0148] In the above embodiment, the drive mechanism 90 may not include the first gear 92 and the second gear 93. In this case, the drive mechanism 90 may also include a first pulley that rotates together with the first shaft 72, a second pulley that rotates together with the second shaft 82, and a belt that is wound around the first pulley and the second pulley. In addition, when the rotation direction of the second gear 93 is set to be opposite to the rotation direction of the first gear 92, the belt is hung in parallel between the first pulley and the second pulley (open transmission belt). In addition, when the rotation direction of the second gear 93 is set to be the same as the rotation direction of the first gear 92, the belt is hung crosswise between the first pulley and the second pulley (cross transmission belt).

[0149] In the above-mentioned embodiment, the driving mechanism 90 may also include a collecting motor that rotates the second shaft 82. In addition, the driving mechanism 90 may also include an unwinding motor that rotates the first shaft 72. In this case, the driving of the collecting motor and the unwinding motor is controlled by the control unit 66. Moreover, for example, it may be configured that, in the case of implementing a process of pasting a cloth onto the adhesive sheet AS unwound from the unwinding unit 71, the control unit 66 controls the driving of the collecting motor based on the unwinding amount of the adhesive sheet AS. Thus, the protective sheet SS peeled off from the adhesive sheet AS can be wound onto the second shaft 82 to a good extent. In addition, in this case, the driving mechanism 90 may not include the first gear 92 and the second gear 93.

[0150] In the above embodiment, the guide portion 81 may not be fixed to the device body 20. Moreover, the first shaft 72 may be rotatably supported on the legs 85R and 85L of the guide portion 81 in the same manner as the second shaft 82. In this case, the first gear 92 is provided at the end of the first shaft 72 in the -X direction in the same manner as the second gear 93. In this case, the force applying portion 76 may be provided on the legs 85R so that the contact body 76p presses the circumferential surface of the first shaft 72 toward the rotation center of the first shaft 72.

[0151] In the above-mentioned embodiment, the guide portion 81 may also be provided with a collecting portion instead of the second shaft 82, and the collecting portion fixes the core tube CT on which the protective sheet SS is wound. The collecting portion may also have the same structure as the unwinding portion 71, for example. In this case, the first shaft 72 of the collecting portion is inserted and fixed to the core tube CT on which the protective sheet SS is wound. Moreover, by rotating the first shaft 72 of the collecting portion, the protective sheet SS is wound onto the core tube CT. In addition, in this case, the second gear 93 may also be provided at the end of the -X direction of the connecting shaft rotatably supported on the foot 85R in the same manner as the first gear 92. Moreover, the second gear 93 may also be connected to the first shaft 72 of the collecting portion by inserting the top end of the connecting shaft into the connecting hole 73h of the first shaft 72 of the collecting portion. Moreover, the first shaft 72 of the collecting portion and the second gear 93 may also be rotated as a whole.

[0152] In the above embodiment, the engaging portion 89 provided at the end of the leg portion 85 in the +Z direction may be a recessed portion opened in the −Z direction so as to be engageable with the protruding engaged portion 79 provided on the device body 20 .

[0153] In the above-mentioned second embodiment, the end 23e of the upper surface 23 in the printing device 11 may not be located on the +Y direction side compared to the front face of the heating unit 51. For example, the end 23e may be located on the -Y direction side compared to the front face of the heating unit 51 as in the first embodiment, or may be located at the same position as the front face of the heating unit 51 in the Y-axis direction. In this case, the fabric F of the pasting specification wound by the winding unit 46 may come into contact with the front face of the heating unit 51 between the end 23e and the winding unit 46.

[0154] In the above-mentioned embodiment, the processing of the fabric F on the adhesive sheet AS may not be performed by pressing the fabric F onto the adhesive sheet AS supported by the upper surface 23. For example, it may be configured such that the fabric F is pasted onto the adhesive sheet AS by pressing the fabric F onto the adhesive sheet AS pulled forward and downward from the unwinding section 71 and supported by the front surface 24 of the device body 20. Furthermore, for example, it may be configured such that the fabric F is pasted onto the adhesive sheet AS by pressing the fabric F onto the adhesive sheet AS pulled forward and downward from the unwinding section 71 and supported by the front surface of the heating section 51. Furthermore, for example, it may be configured such that the fabric F is pasted onto the adhesive sheet AS by pressing the fabric F onto the adhesive sheet AS pulled forward and downward from the unwinding section 71 and supported by the front surface of the heating section 51. Furthermore, for example, it may be configured such that the fabric F is pasted onto the adhesive sheet AS by pressing the fabric F onto the adhesive sheet AS pulled downward from the unwinding section 71 and supported by the back surface 25 of the device body 20 that is downward. In these cases, the front surface 24 and the back surface 25 of the device body 20 and the front surface of the heating unit 51 are examples of the support portion SP that supports the adhesive sheet AS from which the adhesive layer is exposed after the protective sheet SS is peeled off.
