[0003] [Patent Document 1] JP 2018-138361 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, various kinds of printing media are used, and for example, a film may be used as a sheet-shaped printing medium. Films are slippery, and even if a friction member is placed on the platen, it may be difficult to fix the printing medium so that it does not move on the platen. It is possible to fix the sheet-shaped printing medium on the platen using adhesive tape or the like, but it is time-consuming to attach the adhesive tape to the platen. Furthermore, a part of the sheet-shaped printing medium attached with the adhesive tape is likely to be raised, and in such a state, printing defects are likely to occur, so it is often necessary to re-mount the sheet-shaped printing medium. When the sheet-shaped printing medium is fixed on the platen using adhesive tape or the like, it is also time-consuming to re-mount the sheet-shaped printing medium. Therefore, when a sheet-shaped printing medium is used, it is not convenient to place the sheet-shaped printing medium on the platen. [Means for solving the problem]

[0005] In order to solve the above problem, the printing medium loading method of the present invention includes a preparation step of attaching a first side of a double-sided adhesive sheet to a flat loading surface of a platen on which sheet-like printing medium can be placed, and a printing medium loading step of attaching the printing medium to a second side of the double-sided adhesive sheet opposite the first side attached in the preparation step, wherein the double-sided adhesive sheet has an adhesive layer on each of the first and second sides, and the adhesive force of the first side relative to the loading surface is stronger than the adhesive force of the second side relative to the printing medium.

[0006] In addition, to solve the above-mentioned problems, the double-sided adhesive sheet of the present invention is a double-sided adhesive sheet that is used by attaching a first side to a flat loading surface of a platen on which a sheet-like printing medium can be placed, and attaching the printing medium to a second side opposite the first side, and is characterized in that it has an adhesive layer on each of the first and second sides, and the adhesive force of the first side to the loading surface is stronger than the adhesive force of the second side to the printing medium.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] First, the present invention will be briefly described. In order to solve the above problem, a print medium loading method of a first aspect of the present invention comprises a preparation step of attaching a first side of a double-sided adhesive sheet to a flat loading surface of a platen on which a sheet-like print medium can be loaded, and a print medium loading step of attaching the print medium to a second side of the double-sided adhesive sheet opposite the first side attached in the preparation step, wherein the double-sided adhesive sheet has an adhesive layer on each of the first and second sides, and the adhesive force of the first side relative to the loading surface is stronger than the adhesive force of the second side relative to the print medium.

[0009] According to this aspect, preparation for placing a print medium on the platen can be easily performed by using a double-sided adhesive sheet, the first surface of which is attached to the mounting surface of the platen and the print medium is attached to the second surface. Also, since the adhesive force of the first surface to the mounting surface is stronger than the adhesive force of the second surface to the print medium, it is easy to place the print medium again. Therefore, it is possible to improve the convenience when placing the print medium on the platen.

[0010] A second aspect of the printing medium loading method of the present invention is an aspect dependent on the first aspect, characterized in that the platen is mounted on the printing device so as to move back and forth in a direction parallel to the loading surface, and when the adhesive force of the second surface is F2, the mass of the printing medium is m, and the maximum acceleration at which the platen moves is a, F2>m×a is satisfied.

[0011] According to this aspect, when the adhesive force of the second surface is F2, the mass of the print medium is m, and the maximum acceleration at which the platen moves is a, F2>m×a is satisfied. By satisfying this relationship, it is possible to prevent the print medium from peeling off the platen as the platen moves.

[0012] A third aspect of the printing medium loading method of the present invention is an aspect dependent on the second aspect, and is characterized in that when the adhesive force of the first surface is F1 and the mass of the double-sided adhesive sheet is ms, F1>(m+ms)×a is satisfied.

[0013] According to this aspect, when the adhesive force of the first surface is F1 and the mass of the double-sided adhesive sheet is ms, F1>(m+ms)×a is satisfied. By satisfying such a relationship, it is possible to prevent the double-sided adhesive sheet from peeling off from the platen as the platen moves.

[0014] A fourth aspect of the printing medium mounting method of the present invention is an aspect dependent on any one of the first to third aspects, and is characterized in that when the force required to peel the first surface from the mounting surface in a direction intersecting the mounting surface is F1p, and the force required to peel the printing medium from the second surface is F2p, F1p>F2p is satisfied.

[0015] According to this aspect, when the force required to peel the first surface from the placement surface in a direction intersecting with the placement surface is F1p and the force required to peel the print medium from the second surface is F2p, F1p>F2p is satisfied. By satisfying this relationship, it is possible to prevent the double-sided adhesive sheet from peeling off from the platen together with the print medium when the print medium is removed from the platen.

[0016] A fifth aspect of the printing medium loading method of the present invention is an aspect dependent on any one of the first to third aspects, and is characterized in that the first surface has self-adhesive properties.

[0017] According to this aspect, the first surface has self-adhesive properties, which makes it easier to attach the double-sided adhesive sheet to the placement surface.

[0018] A sixth aspect of the printing medium loading method of the present invention is an aspect dependent on any one of the first to third aspects, and is characterized in that the second surface has self-adhesive properties.

[0019] According to this aspect, the second surface has self-adhesive properties, which makes it easier to attach the print medium to the double-sided adhesive sheet.

[0020] A seventh aspect of the printing medium loading method of the present invention is an aspect dependent on any one of the first to third aspects, and is characterized in that in the printing medium loading step, the printing medium is attached to the second surface so that no part of the printing medium comes into contact with the second surface.

[0021] According to this aspect, in the print medium placement step, the print medium is attached to the second surface so that a portion of the print medium does not come into contact with the second surface. Therefore, when removing the print medium from the platen, an operator can remove the print medium from the platen by holding the portion that does not come into contact with the second surface, improving convenience.

[0022] The eighth aspect of the printing medium loading method of the present invention is an aspect dependent on any one of the first to third aspects, and is characterized in that it includes a printing step of printing on the printing medium after the printing medium loading step is performed, and that the printing medium loading step is performed again with unprinted printing medium for newly performing the printing step after removing the printed printing medium after the printing step is performed.

[0023] According to this aspect, the printing medium placement step is performed again with unprinted printing medium for a new printing step after removing the printed printing medium after the printing step is performed. Therefore, the printing step can be suitably performed repeatedly on a plurality of printing media.

[0024] A ninth aspect of the printing medium loading method of the present invention is an aspect dependent on any one of the first to third aspects, and is characterized in that the first surface and the second surface are formed to be distinguishable.

[0025] According to this aspect, the first surface and the second surface are formed to be distinguishable from each other, which makes it possible to prevent the double-sided adhesive sheet from being placed on the platen with the first surface and the second surface mistakenly placed on the platen.

[0026] A print medium loading method according to a tenth aspect of the present invention is an aspect dependent on the ninth aspect, and is characterized in that at least one of the first surface and the second surface has an identification mark.

[0027] According to this aspect, at least one of the first surface and the second surface has an identification marking, which makes it easy to distinguish between the first surface and the second surface, and easily prevents the double-sided adhesive sheet from being placed on the platen with the first surface and the second surface mistakenly placed on the platen.

[0028] The double-sided adhesive sheet of an eleventh aspect of the present invention is a double-sided adhesive sheet which is used by attaching a first side to a flat supporting surface of a platen on which a sheet-like printing medium can be placed, and attaching the printing medium to a second side opposite the first side, and is characterized in that it has an adhesive layer on each of the first and second sides, and the adhesive force of the first side to the supporting surface is stronger than the adhesive force of the second side to the printing medium.

[0029] According to this aspect, preparation for placing a print medium on the platen can be easily performed by using a double-sided adhesive sheet, the first surface of which is attached to the mounting surface of the platen and the print medium is attached to the second surface. Also, since the adhesive force of the first surface to the mounting surface is stronger than the adhesive force of the second surface to the print medium, it is easy to place the print medium again. Therefore, it is possible to improve the convenience when placing the print medium on the platen.

[0030] The print medium loading method and double-sided adhesive sheet of the present invention will be described below with reference to the accompanying drawings. First, an overview of a printing device 1 according to an embodiment that can execute the print medium loading method of the present invention and use the double-sided adhesive sheet of the present invention will be described mainly with reference to Fig. 1. Fig. 1 is a schematic perspective view of the printing device 1 according to this embodiment.

[0031] 1, a printing device 1 of this embodiment is equipped with a medium transport unit 2 having a platen 4 on which a sheet-like printing medium M can be placed. The medium transport unit 2 is configured to be able to move the platen 4 in directions A1 and A2. A main body 3 of the printing device 1 is provided with a printing unit 5 that is able to move back and forth in a scanning direction B that intersects with directions A1 and A2.

[0032] The printing device 1 of this embodiment is configured to move the platen 4 with the printing medium M placed on it in the position shown in Fig. 1 in a direction A1, and then eject ink from the printing unit 5 while moving the platen 4 in a direction A2 to perform printing. The printing device 1 of this embodiment can preferably use a resin film as the printing medium M. Since the film is slippery on the mounting surface 4a of the platen 4 shown in Figs. 3 to 5, it is preferable to provide a member on the mounting surface 4a that can hold the film without slipping. Therefore, in Fig. 1, a double-sided adhesive sheet F is arranged on the mounting surface 4a as a member that can hold the film without slipping.

[0033] A printing medium loading method that can be performed using the printing device 1 of this embodiment, as well as a double-sided adhesive sheet F that can be used with the printing device 1 of this embodiment will be described below with reference to Figures 2 to 7. First, a description will be given from the perspective of the double-sided adhesive sheet F. The double-sided adhesive sheet F that can be used with the printing device 1 of this embodiment is a double-sided adhesive sheet that is used by attaching a first side FA as shown in Figure 4 to a flat loading surface 4a of a platen 4 on which a sheet-like printing medium M as shown in Figure 5 can be placed, and further attaching the printing medium M to a second side FB opposite the first side FA as shown in Figure 3.

[0034] The double-sided adhesive sheet F has an adhesive layer on each of the first surface FA and the second surface FB. Here, the adhesive force of the first surface FA to the mounting surface 4a is configured to be stronger than the adhesive force of the second surface FB to the print medium M. By using such a double-sided adhesive sheet F, which is used by attaching the first surface FA to the mounting surface 4a of the platen 4 and attaching the print medium M to the second surface FB, preparation for placing the print medium M on the platen 4 can be easily performed. This is because even if the print medium M is placed on the mounting surface 4a in a bent state, it can be easily re-placed many times. In addition, since the adhesive force of the first surface FA to the mounting surface 4a is stronger than the adhesive force of the second surface FB to the print medium M, it is particularly easy to re-place the print medium M. This is because the double-sided adhesive sheet F is attached to the print medium M when the print medium M is re-placed, and the double-sided adhesive sheet F can be prevented from peeling off from the platen 4. Therefore, by using such a double-sided adhesive sheet F, it is possible to improve the convenience when placing the print medium M on the platen 4. Furthermore, when the double-sided adhesive sheet F becomes dirty or deteriorated, it is possible to replace the double-sided adhesive sheet F itself by peeling off the first surface FA from the placement surface 4a.

[0035] Next, a description will be given from the perspective of a print medium mounting method using the printing device 1 of this embodiment. In the print medium mounting method of this embodiment, as shown in the flowchart of Fig. 6, first, in step S110, a double-sided adhesive sheet F is attached to the mounting surface 4a of the platen 4 so as to change from the state shown in Fig. 5 to the state shown in Fig. 4. In detail, step S110 corresponds to a preparation step of attaching a first surface FA of the double-sided adhesive sheet F to the flat mounting surface 4a of the platen 4 on which a sheet-like print medium M can be placed.

[0036] Next, in the printing medium placement step of step S120, the printing medium M is attached to the second surface FB opposite to the first surface FA of the double-sided adhesive sheet F attached to the placement surface 4a in the preparation step of step S110 so as to be in the state shown in FIG. 2 and FIG. 3. As described above, the double-sided adhesive sheet F has an adhesive layer on each of the first surface FA and the second surface FB, and the adhesive force of the first surface FA to the placement surface 4a is stronger than the adhesive force of the second surface FB to the printing medium M. In this way, by using the double-sided adhesive sheet F, which is used by attaching the first surface FA to the placement surface 4a of the platen 4 and attaching the printing medium M to the second surface FB, preparation for placing the printing medium M on the platen 4 can be easily performed. In addition, since the adhesive force of the first surface FA to the placement surface 4a is stronger than the adhesive force of the second surface FB to the printing medium M, it is easy to re-place the printing medium M. Therefore, by performing the printing medium placement method of this embodiment, it is possible to improve the convenience when placing the printing medium M on the platen 4.

[0037] Next, after execution of the print medium placement process in step S120, in the printing process in step S130, ink is ejected from the printing unit 5 onto the print medium M transported by the medium transport unit 2, to print on the print medium M. Then, in the print medium removal process in step S140, the print medium M printed in the printing process in step S130 is removed from the platen 4. Then, in step S150, it is determined whether or not to print on new print medium M, and if it is determined that new print medium M will be printed on, the process returns to the print medium placement process in step S120, and if it is determined that new print medium M will not be printed on, the print medium placement method of this embodiment is terminated.

[0038] That is, the printing medium placement step in step S120 is performed again on the pre-printing printing medium for executing the printing step in step S130 after removing the post-printing printing medium after the execution of the printing step in step S130. The post-printing printing medium is the printing medium M on which printing has been performed by executing the printing step in step S130, and the pre-printing printing medium is the printing medium M before executing the printing step in step S130 that is about to be newly printed. By adopting such a printing medium placement method, the printing step in step S130 can be preferably repeatedly executed for a plurality of printing media M.

[0039] For the double-sided adsorption sheet F used in such a printing medium placement method, it is preferable that the first surface FA and the second surface FB are formed so as to be distinguishable. This is because, by forming the first surface FA and the second surface FB so as to be distinguishable, it is possible to prevent the double-sided adsorption sheet F from being placed on the platen 4 by mistake between the first surface FA and the second surface FB.

[0040] An example of a case where the first surface FA and the second surface FB are formed to be distinguishable from each other is when at least one of the first surface FA and the second surface FB has an identification mark Fm. FIG. 2 shows how the identification mark Fm formed on the second surface FB of the double-sided adhesive sheet F can be recognized through the printing medium M, which is a transparent film. In the double-sided adhesive sheet F of this embodiment, an identification mark Fm with "OK" written thereon is formed on the second surface FB of the double-sided adhesive sheet F. When the identification mark Fm is viewed from the second surface FB side, the character "OK" can be recognized, but when the identification mark Fm is viewed from the first surface FA side, the character "OK" is inverted and is not the correct character. Therefore, by attaching the first surface FA of the double-sided adhesive sheet F to the placement surface 4a, the character "OK" can be recognized. Therefore, by having the identification mark Fm on the double-sided adhesive sheet F, the first surface FA and the second surface FB can be easily distinguished from each other by the identification mark Fm, and it is easy to prevent the printing medium M from being placed on the platen 4 by mistakenly placing the first surface FA and the second surface FB. The identification marking Fm may be formed on the first surface FA as long as it can be recognized as a correct character when viewed from the second surface FB and is visible through the double-sided adhesive sheet F. Furthermore, the identification marking Fm may be a symbol or a design other than a character as long as it is possible to recognize whether it is in the correct orientation or inverted.

[0041] The platen 4 is mounted on the printing device 1 of this embodiment so as to move back and forth in directions A1 and A2, which are parallel to the placement surface 4a. Here, in the printing device 1 of this embodiment, when the adhesive force of the second surface FB to the printing medium M is F2, the mass of the printing medium M is m, and the maximum acceleration when the platen 4 moves back and forth in directions A1 and A2 is a, F2>m×a is satisfied. By satisfying this relationship, it is possible to prevent the printing medium M from peeling off the platen 4 as the platen 4 moves.

[0042] The adsorption force can be ensured, for example, by using a silicone adhesive composition or the like in the adsorption layer of the double-sided adhesive sheet F. For example, a preferred adsorption layer can be obtained by applying a silicone adhesive composition or the like to the first surface FA and the second surface FB and curing them under predetermined conditions. The adsorption force can be measured, for example, by the 180° peel adhesion measurement method shown in JIS Z 0237. When a silicone adhesive composition or the like is used in the adsorption layer of the double-sided adhesive sheet F, adjustment of the adsorption force can be achieved, for example, by adjusting the alkenyl group. On the other hand, when another adhesive composition or the like is used in the adsorption layer of the double-sided adhesive sheet F, adjustment of the adsorption force can be achieved by selecting the type of components other than the base polymer in the adhesive to obtain the adsorption layer and adjusting the amount of the components to be blended. Examples of the components include crosslinking agents, silane coupling agents, and oligomers.

[0043] As the double-sided adhesive sheet F and the printing medium M, for example, a plastic film substrate made of polyester, poly(meth)acrylate, polycarbonate, polyethylene, polypropylene, polystyrene, polyamide, polyimide, polyphenylene sulfide, polytetrafluoroethylene, polyvinyl chloride, polyurethane, triacetyl cellulose, polyacetal, norbornene resin ("Arton" (registered trademark), manufactured by JSR Corporation), cycloolefin resin (manufactured by Nippon Zeon Co., Ltd., "ZEONOR" (registered trademark)), epoxy resin, phenolic resin, etc., or a composite substrate made by laminating a plurality of these may be used. In addition, polyester films such as polyethylene terephthalate, polybutylene terephthalate, and polyethylene naphthalate, polyimide films, polyacrylate films such as polyacrylate and polymethacrylate, and polycarbonate films are preferable. On the other hand, various acrylic resins can be preferably used as the platen 4.

[0044] Furthermore, in the printing apparatus 1 of this embodiment, when the adhesive force of the first surface FA is F1 and the mass of the double-sided adhesive sheet F is ms, F1>(m+ms)×a is satisfied. By satisfying such a relationship, it is possible to prevent the double-sided adhesive sheet F from peeling off from the platen 4 as the platen 4 moves.

[0045] Furthermore, in the printing device 1 of this embodiment, when the force required to peel the first surface FA from the mounting surface 4a in the vertical direction that intersects with the mounting surface 4a is F1p and the force required to peel the print medium M from the second surface FB is F2p, F1p>F2p is satisfied. By satisfying such a relationship, it is possible to prevent the double-sided adhesive sheet F from peeling off from the platen 4 together with the print medium M when the print medium M is removed from the platen 4.

[0046] Protective films are commonly used to protect the screens of smartphones and tablets. The technology of the adhesive layer used in such protective films can be adapted for use as the double-sided adhesive sheet F.

[0047] Here, the first surface FA of the double-sided adhesive sheet F of this embodiment has self-adhesive properties. Since the first surface FA of the double-sided adhesive sheet F has self-adhesive properties in this manner, it is possible to improve the convenience when attaching the double-sided adhesive sheet F to the placement surface 4a.

[0048] Furthermore, the second surface FB of the double-sided adhesive sheet F of this embodiment also has self-adhesive properties. Since the second surface FB of the double-sided adhesive sheet F has self-adhesive properties in this manner, it is possible to improve the convenience when attaching the print medium M to the double-sided adhesive sheet F.

[0049] Self-adhesiveness is a layer in which the adhesive layer has low adhesive strength, so that it can be easily peeled off from the component when peeled off, and quickly blends with the component when attached. In other words, when pressed against a smooth surface, it can adhere by its own adhesive strength even without adhesive or pressure sensitive adhesive, and can be easily peeled off as needed. By making the adhesive layer self-adhesive, it is possible to prevent air bubbles from being mixed in, and even if air bubbles are mixed in, they can be eliminated over time.

[0050] At least one of the first surface FA and the second surface FB of the double-sided adhesive sheet F may be subjected to an antistatic treatment. The antistatic treatment can be carried out using an antistatic agent such as a surfactant-based, silicone-based, organoboron-based, conductive polymer-based, metal oxide-based, or vapor-deposited metal-based agent.

[0051] Furthermore, in the print medium placement process in step S120 described above, it is preferable to attach the print medium M to the second surface FB so that a portion of the print medium M does not come into contact with the second surface FB. For example, as shown in Fig. 2, the print medium M can be attached to the second surface FB so that a portion of the print medium M does not come into contact with the second surface FB by forming at least one of the four corners of the substantially rectangular double-sided adhesive sheet F into a chamfered or rounded shape, or by making the double-sided adhesive sheet F slightly smaller than the print medium M when viewed from the front.

[0052] By attaching the printing medium M to the second surface FB so that a portion of the printing medium M does not come into contact with the second surface FB, an operator can remove the printing medium M from the platen 4 by holding the portion that does not come into contact with the second surface FB, thereby improving convenience. For example, an operator can easily remove the printing medium M from the platen 4 by hooking his or her fingers on two of the four corners of the rectangular printing medium M, which is the portion of the printing medium M that does not come into contact with the second surface FB.

[0053] Furthermore, as a configuration for attaching the printing medium M to the second surface FB so that a portion of the printing medium M does not come into contact with the second surface FB, the double-sided adhesive sheet F may be disposed only on a portion of the mounting surface 4a of the platen 4. In Fig. 7, the double-sided adhesive sheet F is disposed in two places along the long side of the mounting surface 4a of the platen 4. With this configuration, when removing the printing medium M from the platen 4, the worker can easily remove the printing medium M from the platen 4 by holding the portion that does not come into contact with the second surface FB, improving convenience.

[0054] The present invention is not limited to the above embodiment, and various modifications are possible within the scope of the invention described in the claims, and it goes without saying that these modifications are also included in the scope of the present invention. Also, instead of using the double-sided adhesive sheet F, it is possible to use a printing device 1 having an adhesive layer on the mounting surface 4a of the platen 4. [Explanation of symbols]
