[0004] PATENT DOCUMENT
[0005] Patent Document 1: Japanese Patent Application Publication No. 2018-138362 SUMMARY
[0006] PROBLEMS TO BE SOLVED BY THE INVENTION
[0007] In the above-described printing device, depending on the kind of cloth, if ink adheres, the cloth can shrink. Then, ink that is ejected afterward can deviate from a desired position of the cloth to which the ink adheres.
[0008] An object of the present disclosure is to provide a platen and a printing device that can reduce the possibility that a position to which ink that is ejected adheres deviates from a desired position of a cloth.
[0009] MEANS FOR SOLVING THE PROBLEMS
[0010] A first aspect of the present disclosure relates to a platen that supports a cloth on which ink is ejected by an inkjet head, characterized by including a plurality of protrusions that protrude upward from an upper surface of the platen, the tips of the protrusions having shapes that hook pile or fiber of the cloth.
[0011] Since the tips of the protrusions of the platen of the first aspect hook the pile or fiber of the cloth, the amount by which the cloth shrinks due to the ink is reduced. Thus, it is possible to reduce the possibility that a position to which ink that is ejected adheres deviates from a desired position of the cloth.
[0012] It can be that the platen extends in a first direction orthogonal to an up-down direction and in a second direction orthogonal to the up-down direction and the first direction, and the plurality of protrusions protrude from the upper surface of the platen toward the upper side and toward the outside of the platen in the first direction and the second direction.
[0013] In this case, the platen can reduce the amount by which the cloth that is to be shrunk toward the inside of the platen shrinks, using the protrusions.
[0014] It can be that the plurality of protrusions protrude toward a direction in which the cloth is detached from the platen as the outside.
[0015] In a case where the user detaches the cloth from the platen toward the detachment direction, since the protrusions protrude toward the upper side and the detachment direction, the hooking of the detached cloth with the protrusions is reduced.
[0016] It can be that the platen supports a garment as the cloth, a positioning portion that positions a collar of the garment is provided at an end portion of the platen in the first direction, and a plurality of the protrusions protrude toward the upper side and the end portion.
[0017] In a case where the user detaches the garment from the platen toward the end portion, since the protrusions protrude toward the upper side and the end portion, the hooking of the detached garment with the protrusions is reduced.
[0018] It can be that the plurality of the protrusions are provided on the entire surface of the upper surface.
[0019] In this case, with the platen, the amount of shrinkage of the cloth due to the ink can be reduced compared to a case where the protrusions are provided on a portion of the upper surface.
[0020] A second aspect of the present disclosure relates to a printing device characterized by including an inkjet head that ejects ink onto a cloth and a platen that supports the cloth, the platen including a plurality of protrusions that protrude upward from an upper surface, the tips of the protrusions having a shape that hooks nap or fibers of the cloth.
[0021] The printing device of the second aspect can have the same effects as the first aspect.
[0022] It can be that the inkjet head includes a base inkjet head that ejects base ink and a color inkjet head that ejects color ink onto the base ink.
[0023] The printing device can reduce the likelihood that the position at which the ejected color ink adheres to the cloth deviates from the position at which the base ink adheres to the cloth, since the amount of shrinkage of the cloth due to the base ink is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0040] An embodiment of the present disclosure relating to a printer 1 and a platen 5 will be described with reference to the drawings. Figure 1 The printer 1 shown is an inkjet printer that performs printing by ejecting ink onto a cloth as a print medium. The cloth is, for example, a cloth, a felt, or the like, and in this embodiment, a T-shirt 90. Figure 1 The upper, lower, lower left, upper right, lower right, and upper left of the printer 1 and the platen 5 are the upper, lower, front, rear, right, and left, respectively. In the present embodiment, the mechanical elements in the drawings show actual scales.
[0041] Referring to Figure 1 , the general structure of the printer 1 will be described. As shown in Figure 1 , the printer 1 includes a housing 2, a conveyance section 6, a platen support member 3, and a platen 5. The housing 2 is rectangular parallelepiped. An opening section 21 is formed in the housing 2. The opening section 21 extends from the front surface to the rear surface of the housing 2. An input section 46 is provided on the right side of the opening section 21 in the front surface of the housing 2. A user inputs various information to the printer 1 by operating the input section 46.
[0042] The conveyance section 6 is provided at the lower portion of the opening section 21 and conveys the platen support member 3 in the front-rear direction. In detail, the conveyance section 6 includes a pair of rails 12 as shown in Figure 2 . The pair of rails 12 are arranged in the left-right direction and extend in the front-rear direction. The platen support member 3 is positioned above the conveyance section 6 and is supported by the pair of rails 12. A sub-scanning motor (not shown) is provided at the lower portion of the platen support member 3. The platen support member 3 is movable in the front-rear direction along the pair of rails 12 by driving of the sub-scanning motor.
[0043] The platen 5 is disposed in the opening section 21 in the main view. The platen 5 is supported by the platen support member 3 and is movable in the front-rear direction together with the platen support member 3 between a printing position and a loading-unloading position. That is, the front-rear direction of the printer 1 is a sub-scanning direction. The printing position is a position at which the platen 5 faces the heads 100, 200 described later inside the housing 2. The loading-unloading position is a position shown in Figure 1 , which is forward of the printing position. In a case where the platen 5 is in the loading-unloading position, the platen support member 3 and the platen 5 reach the front end portions of the pair of rails 12, and the platen support member 3 is disposed outside the housing 2. Details of the configuration of the platen 5 will be described later. A T-shirt 90 is placed on the upper surface of the platen 5 as an example of a cloth.
[0044] As shown in Figure 2 , the printer 1 includes the rails 11, the guide shaft 9, the carriage 20, and the heads 100, 200 in the housing 2 shown in Figure 1 . The rails 11 are provided at the upper rear portion of the printer 1 and extend in the left-right direction. The guide shaft 9 is provided at the front of the rails 11 and extends in the left-right direction. The carriage 20 is positioned between the front-rear direction of the rails 11 and the guide shaft 9 and is supported by the rails 11 and the guide shaft 9. The main scanning motor 19 is provided at the right side of the right end portion of the guide shaft 9. The carriage 20 is movable in the left-right direction along the rails 11 and the guide shaft 9 by driving of the main scanning motor 19.
[0045] The heads 100, 200 are arranged in the front-rear direction and mounted on the carriage 20, and move in the left-right direction together with the carriage 20. The head 100 is located further rearward than the head 200. The heads 100, 200 each have a nozzle (not shown) at a lower portion, and eject ink downward from the nozzle.
[0046] The printer 1 is capable of printing a color image on a print medium using ink of five colors, white, black, yellow, cyan, and magenta. Hereinafter, the ink of white among the ink of five colors is referred to as white ink, and the ink of four colors, black, yellow, cyan, and magenta, is collectively referred to as color ink. In the case where white ink and color ink are collectively referred to or in the case where it is not determined which one is, it is simply referred to as ink. The white ink is used in printing as a portion that displays white of an image or as a base for other color ink. The color ink is ejected onto the base formed by the white ink, and is used for printing of a color image.
[0047] The head 100 ejects white ink from the nozzle. The head 200 ejects color ink from the nozzle.
[0048] Reference Figure 3 , Figure 4 , an example of a detailed configuration of the platen 5 is described. The platen 5 has a plate 50, an adhesive member 8, and a sheet 7. The plate 50 extends in the front-rear direction and the left-right direction, and is a rectangular shape in plan view that is long in the front-rear direction, for example, and is composed of metal. The adhesive member 8 and the sheet 7 are stacked in order from below on the upper surface of the plate 50. The adhesive member 8 is, for example, a double-sided tape that fixes the plate 50 and the sheet 7. As shown in Figure 3 , the sheet 7 covers the entire surface of the upper surface of the plate 50 in plan view. Therefore, the platen 5 is the same shape as the plate 50 in plan view, and is a rectangular shape in plan view in which the long side direction is the front-rear direction and the short side direction is the left-right direction.
[0049] As shown in Figure 4 , a plurality of protruding portions 71 are provided on the entire surface of the upper surface 70 of the sheet 7 at regular intervals. The protruding portions 71 protrude upward and forward from the upper surface 70 of the sheet 7, for example. The plurality of protruding portions 71 are, for example, members of one side of a hook-shaped pile of a hook-and-loop fastener. The protruding portions 71 taper from the base toward the tip. The height of the protruding portions 71 is, for example, 1.7 mm. The protruding portions 71 taper from the base toward the tip, for example. As shown in Figure 6 , the tip hooks the fiber 92 of the T-shirt 90 provided to the platen 5. In addition, since the protruding portions 71 protrude upward and forward from the upper surface 70 of the sheet 7, the hooking of the T-shirt 90 by the protruding portions 71 is reduced in the case where the T-shirt 90 is pulled forward and detached from the platen 5.
[0050] As shown in Figure 3As shown, a positioning part 51 is provided at the front end 53 of the platform 5. The positioning part 51 is a rod-shaped member that extends forward from the left and right sides toward the center when viewed from above. The rear end of the positioning part 51 is fastened to the plate 50 by a fastening member (not shown) through a plurality of holes 52 that pass through the right front and left front parts of the plate 50 in the vertical direction.
[0051] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 This describes the general outline of printing in printer 1. First, the user moves the table 5 to the input section 46. Figure 1 The loading and unloading positions are shown. The user holds the T-shirt 90 with the neckline 91 facing forward and the hem in the front-to-back direction, and moves the T-shirt 90 backward so that it covers the platform 5 from the hem side. At this time, the T-shirt 90 moves in a state where it is separated from the top of the piece 7.
[0052] like Figure 5 As shown, the neckline 91 abuts against the positioning part 51, completing the positioning of the T-shirt 90 relative to the platform 5. The user places the T-shirt 90 on the sheet 7 and mounts it on the platform 5. At this time, as... Figure 6 As shown, the top of the protrusion 71 hooks onto the fibers 92 of the T-shirt 90 mounted on the printing plate 5. The user moves the printing plate 5, on which the T-shirt 90 is mounted, from the loading / unloading position to the printing position by operating the input unit 46.
[0053] Printer 1 ejects white ink from head 100 and color ink from head 200 while scanning the carriage 20 in the left-right direction. After the ink ejection based on one scan is completed, printer 1 moves the platform 5 forward and again ejects ink from heads 100 and 200 while scanning the carriage 20 in the left-right direction. Since head 100 is located further back than head 200, the color ink is ejected onto the white ink. That is, the white ink is used as a base for the color ink.
[0054] If white ink, which serves as a base, is sprayed from the head 100 and adheres to the T-shirt 90, the T-shirt 90 may shrink due to the white ink. If the T-shirt 90 shrinks, the subsequent colored ink may adhere to a position different from where the white ink adhered. Because the tip of the protrusion 71 of the printing plate 5 hooks onto the fibers 92 of the T-shirt 90, the amount of shrinkage of the T-shirt 90 due to the white ink is reduced. Therefore, the possibility of the colored ink adhering to the T-shirt 90 deviating from the position where the white ink adhered is reduced, resulting in the desired printing result.
[0055] After printer 1 finishes printing on T-shirt 90, it moves table 5 to... Figure 1The user holds the collar 91 and pulls the T-shirt 90 forward to detach the T-shirt 90 from the table 5. At this time, the T-shirt 90 slides on the sheet 7. Since the protrusions 71 protrude upward and forward from the upper surface 70 of the sheet 7, the T-shirt 90 sliding on the sheet 7 is not hooked by the protrusions 71 and is detached from the table 5.
[0056] As described above, the table 5 includes the plate 50, the adhesive member 8, and the sheet 7. The adhesive member 8 and the sheet 7 are loaded on the upper surface of the plate 50 in this order from below. The sheet 7 includes a plurality of protrusions 71 arranged at a predetermined interval. The protrusions 71 protrude upward and forward from the upper surface 70 of the sheet 7. As shown in Figure 6 As shown, the tips of the protrusions 71 hook the fibers 92 of the T-shirt 90 provided on the table 5. Thus, the amount of shrinkage of the T-shirt 90 due to the ink is reduced. Therefore, the table 5 can reduce the possibility that the position to which the ejected ink adheres deviates from the desired position of the T-shirt 90.
[0057] The protrusions 71 are provided on the entire upper surface 70 of the sheet 7 at a predetermined interval. In this case, for the table 5, the amount of shrinkage of the T-shirt 90 due to the ink can be reduced compared to the case where the protrusions 71 are provided on a part of the upper surface 70 of the sheet 7.
[0058] The table 5 extends in the front-rear direction and the left-right direction, and the protrusions 71 protrude upward and forward from the upper surface 70 of the sheet 7. In the case where the user pulls the T-shirt 90 forward to detach it from the table 5, the detached T-shirt 90 is less likely to be hooked by the protrusions 71.
[0059] The positioning portion 51 that positions the collar 91 of the T-shirt 90 is provided at the front end portion 53 of the table 5. The protrusions 71 protrude upward and forward. That is, the protrusions 71 protrude toward the front end portion 53 of the table 5. Thus, in the case where the user holds the collar 91 and pulls the T-shirt 90 forward when detaching the T-shirt 90 from the table 5, the detached T-shirt 90 is less likely to be hooked by the protrusions 71.
[0060] The printer 1 includes the heads 100, 200 that eject ink to the T-shirt 90 and the table 5 that supports the T-shirt 90. Since the tips of the protrusions 71 of the table 5 hook the fibers 92 of the T-shirt 90, the amount of shrinkage of the T-shirt 90 due to the ink is reduced. Therefore, the printer 1 can reduce the possibility that the position to which the ejected ink adheres deviates from the desired position of the T-shirt 90.
[0061] The printer 1 has the head 100 that ejects white ink used as a base in printing, and the head 200 that ejects color ink onto the white ink. The printer 1 can reduce the possibility that a position at which the ejected color ink adheres to the T-shirt 90 deviates from a position at which the white ink adheres to the fabric, due to the amount by which the T-shirt 90 shrinks due to the white ink.
[0062] In the above-described embodiment, the heads 100, 200 correspond to "inkjet heads" of the present disclosure. The T-shirt 90 corresponds to "fabric" or "clothing" of the present disclosure. The printer 1 corresponds to "printing device" of the present disclosure. The white ink corresponds to "base ink" of the present disclosure. The head 100 corresponds to "base inkjet head" of the present disclosure. The head 200 corresponds to "color inkjet head" of the present disclosure. The board 50 extends in the first direction and the second direction. An example of the first direction is the front-rear direction, and an example of the second direction is the left-right direction. The T-shirt 90 is detached from the table board 5 by being pulled out in the front direction. An example of the direction of detachment is the front direction. The upper surface 70 of the sheet 7 is an example of "upper surface" of the present disclosure. The front end portion 53 of the table board 5 is an example of "one end portion" of the present disclosure.
[0063] The present disclosure can be variously changed from the above-described embodiment. The various modified examples described below can be combined as long as there is no contradiction. For example, the present disclosure can also be applied to a printer of a type different from the inkjet type like the above-described embodiment.
[0064] In the above-described embodiment, the T-shirt 90 is exemplified as the fabric, but is not limited thereto. The fabric can be, for example, various shirts such as a dress shirt, pants, a skirt, a handkerchief, the fabric itself, and the like. The fabric is not limited to cloth, and can be nonwoven fabric such as felt. The top end of the protruding portion 71 is not limited to hooking the fibers of the fabric, and can hook the pile. With the top end of the protruding portion 71, in the case of printing to nonwoven fabric, the amount by which the nonwoven fabric shrinks due to the ink is also reduced. Therefore, the table board 5 can reduce the possibility that a position at which the ejected ink adheres to the nonwoven fabric deviates from a desired position of the nonwoven fabric.
[0065] In the above-described embodiment, the protruding portion 71 protrudes upward and forward from the upper surface of the table board 5, but the direction in which the protruding portion 71 protrudes is not limited thereto. For example, as shown in Figure 7 (A), the protruding portion 71 protrudes upward. The protruding portion 71 can also protrude radially outward from the center of the table board 5 in the front-rear direction and the left-right direction. With the T-shirt 90 installed on the table board 5, an image is often printed to a position corresponding to the center portion of the upper surface of the table board 5, and is likely to shrink inward of the table board 5 in the front-rear direction and the left-right direction due to the ink. Since the protruding portion 71 protrudes in the above-described direction, the top end of the protruding portion 71 is likely to hook the pile or fibers of the fabric. Thus, the table board 5 can reduce the amount of shrinkage of the T-shirt 90 that is to shrink inward.
[0066] In addition, as shown in Figure 7 (B), the protrusions 71 can also be protruded radially from the center of the left and right direction of the rear end portion of the table 5, instead of the center of the table 5. In this case, the table 5 can reduce the amount of contraction of the T-shirt 90 to be contracted toward the inside and reduce the hooking of the T-shirt 90 pulled out to the front and detached from the protrusions 71.
[0067] The shape of the protrusions can also be appropriately changed. The shape of the protrusions is only the shape in which the tip hooks the pile or fiber of the cloth. The shape in which the tip of the protrusions hooks the pile or fiber of the cloth is, for example, the shape in which the tip of the protrusions protrudes in at least any one of the front, rear, left, and right directions from the base. The protrusions are preferably the hook shape extending upward from the base and protruding in at least any one of the front, rear, left, and right directions therefrom, or the shape having an angular portion in which the tip is not curved. Such a shape of the member is, for example, the member provided on the side of the hook-shaped pile of the hook-and-loop fastener. In addition, the protrusions can also be the fiber material or pile seen in the brush for clothes or a vacuum cleaner. The fiber material of the protrusions protrudes several millimeters or so upward from the upper surface 70 of the sheet 7. The protrusions preferably protrude upward and in at least any one of the front, rear, left, and right directions, and it is desirable that the protrusions protrude toward the front direction in which the T-shirt 90 is detached.
[0068] As shown in Figure 8 , the protrusions 72 as the first modification example of the protrusions are inverted J-shaped, and are the shape in which the base is tapered toward the tip and extends upward, and then extends forward while bending. Since the protrusions 72 firmly hold the hooked pile or fiber of the cloth, the amount of contraction of the cloth due to the ink is also reduced in the first modification example.
[0069] In addition, the protrusions 73 as the second modification example of the protrusions are so-called mushroom-shaped in the hook-and-loop fastener. The protrusions 73 are the shape in which the base extends upward, and then the upper end portion protrudes in the front and rear directions, respectively, as shown in Figure 9 , although not shown, the protrusions 73 also protrude in the left and right directions, respectively, like the front and rear directions. The protrusions 73 have no directionality in the front and rear directions and the left and right directions. Since the protrusions 73 also firmly hold the hooked pile or fiber of the cloth like the protrusions 72, the amount of contraction of the cloth due to the ink is also reduced in the second modification example. The protrusions 73 can protrude in any one of the front and rear directions and the left and right directions.
[0070] In addition, as shown in Figure 10 , the protrusions 74 as the third modification example of the protrusions are inverted trapezoidal in the right view in which the tip is expanded more than the base. Since the protrusions 74 can hook the pile or fiber of the cloth with a simple configuration, the amount of contraction of the cloth due to the ink is also reduced in the third modification example.
[0071] In addition, as shown in Figure 11 、 Figure 12 the fourth modification of the protruding portion 75 is a needle shape extending in the up-down direction. The plate 50 is provided with a plurality of grooves 76 recessed downward from the upper surface 54 of the plate 50 and extending in the front-rear direction and the left-right direction. The protruding portion 75 is provided at the intersection of the groove 76 extending in the front-rear direction and the groove 76 extending in the left-right direction. The tip end of the protruding portion 75 protrudes upward from the upper surface 54 of the plate 50. The tip end of the protruding portion 75 pierces the cloth placed on the platen 5 and hooks. Thus, in the fourth modification, the amount by which the cloth shrinks due to the ink is also reduced. In the fourth modification, the upper surface 54 of the plate 50 is an example of the "upper surface" of the present disclosure.
[0072] The shape of the protruding portion can be any shape as long as it has a shape in which the tip end hooks the fluff or fiber of the cloth, as in the above-described modifications. Different shapes of protruding portions can also be provided in combination in the sheet 7. For example, the protruding portion 71 and the protruding portion 73 can also be provided in the left-right direction in an alternating arrangement in the sheet 7.
[0073] The protruding portions 71 to 75 can also be provided only on a portion of the upper surface of the platen 5. For example, the protruding portions 71 to 75 can also be provided only on the upper surface of the platen 5 corresponding to a position where the chances of being printed in the T-shirt 90 are high (for example, the central portion of the T-shirt 90).
[0074] In the above-described embodiment, the shapes of the platen 5 and the plate 50 are rectangular in plan view with the front-rear direction as the long side direction and the left-right direction as the short side direction, but are not limited thereto. The shapes of the platen 5 and the plate 50 can also be rectangular in plan view with the left-right direction as the long side direction and the front-rear direction as the short side direction, or can also be square. In the case where the T-shirt 90 is detached in the left direction or the right direction or the positioning portion 51 is provided at the right end portion or the left end portion of the platen 5, an example of the first direction is the left-right direction, and an example of the second direction is the front-rear direction.
[0075] In the above-described embodiment, the double-sided tape is exemplified as the adhesive member 8, but is not limited thereto. For example, an adhesive such as paste can also be used. In addition, the plate 50 and the sheet 7 can also be fixed by a method other than the adhesive member 8. For example, the sheet 7 can also be fixed by sandwiching the sheet 7 between a frame portion covering the edge portion of the upper surface of the plate 50 and the plate 50. In addition, the sheet 7 can also be fixed to the upper surface of the plate 50 by both the adhesive member 8 and the frame portion.
[0076] The structure of the positioning portion 51 can also be changed as appropriate. For example, a mark for positioning the neckline 91 of the T-shirt 90 can also be provided at the front end portion of the upper surface of the plate 50, and this can be provided as the positioning portion 51. In addition, the positioning portion 51 can also not be provided on the platen 5.
[0077] For example, the printer 1 can also be a structure that moves the platen 5 in the main scanning direction without moving the heads 100, 200. That is, the printer 1 can move the heads 100, 200 and the platen 5 relatively.
[0078] The carriage 20 can carry at least one of the heads 100, 200. For example, the carriage 20 can carry only the head 200. The ink ejected from the heads 100, 200 can also be changed as appropriate.
[0079] In the above-described embodiment, the platen 5 moves in the front-rear direction to the attachment / detachment position and the printing position, but the position to which the platen 5 moves is not limited thereto. For example, the platen 5 can move to an attachment position, a printing position, and a detachment position. The attachment position is the same position as the attachment / detachment position shown in FIG. 1. The detachment position is a position further to the rear than the printing position. In a case where the platen 5 is in the detachment position, the platen support member 3 and the platen 5 reach the rear end portions of the pair of rails 12. Figure 1
[0080] The user sets the cloth on the platen 5 in the attachment position. The printer 1 moves the platen 5 to the printing position to perform printing on the cloth. The printer 1 moves the platen 5 to the detachment position when the printing is completed. The user pulls the cloth to the rear and detaches the cloth from the platen 5. In this modification, since the cloth is pulled to the rear and detached from the platen 5, the protrusions 71 preferably protrude upward and to the rear from the upper surface of the platen 5.
[0081] The platen 5 can also have a frame 5Fa. As shown in FIG. 10, the frame 5Fa surrounds the plate 50 of the platen 5 from the outside in the front-rear and left-right directions. The upper portion of the frame 5Fa extends to the inside in the front-rear and left-right directions and contacts the upper surface 70 of the platen 5. Thus, in a case where the frame 5Fa is placed from above to the plate 50 in a state where the cloth is set on the upper surface 70 as shown in FIG. 11, the frame 5Fa fixes the cloth to the upper surface 70. As a result, the cloth set on the platen 5 is hooked by the tips of the protrusions 71 to 75 and is sandwiched by the frame 5Fa, and thus the amount by which the cloth shrinks due to the ink is further reduced. Thus, the platen 5 can further reduce the possibility that the position at which the ejected ink adheres to the cloth deviates from the desired position of the cloth. Figure 13 Figure 14 In the above-described embodiment, the platen 5 moves in the front-rear direction to the attachment / detachment position and the printing position, but the position to which the platen 5 moves is not limited thereto. For example, the platen 5 can move to an attachment position, a printing position, and a detachment position. The attachment position is the same position as the attachment / detachment position shown in FIG. 1. The detachment position is a position further to the rear than the printing position. In a case where the platen 5 is in the detachment position, the platen support member 3 and the platen 5 reach the rear end portions of the pair of rails 12.
[0082] In the above-described embodiment, the platen 5 moves in the front-rear direction to the attachment / detachment position and the printing position, but the position to which the platen 5 moves is not limited thereto. For example, the platen 5 can move to an attachment position, a printing position, and a detachment position. The attachment position is the same position as the attachment / detachment position shown in FIG. 1. The detachment position is a position further to the rear than the printing position. In a case where the platen 5 is in the detachment position, the platen support member 3 and the platen 5 reach the rear end portions of the pair of rails 12. Figure 13 Figure 14 In the above-described embodiment, the platen 5 moves in the front-rear direction to the attachment / detachment position and the printing position, but the position to which the platen 5 moves is not limited thereto. For example, the platen 5 can move to an attachment position, a printing position, and a detachment position. The attachment position is the same position as the attachment / detachment position shown in FIG. 1. The detachment position is a position further to the rear than the printing position. In a case where the platen 5 is in the detachment position, the platen support member 3 and the platen 5 reach the rear end portions of the pair of rails 12. Figure 15 Figure 16 As shown, the frame 5Fb can be rotated upward from a position in which the front end is in contact with the plate 50, with the joint portion 5C as the center of rotation. Since the frame 5Fb is joined to the plate 50, alignment of the frame 5Fb and the plate 50 becomes easy. Note that in the embodiment, the adhesive member 8 and the sheet 7 are not shown.
