In the present embodiment, in order to attach the protective sheet 200 to the electronic device 900, the first composite sheet 600 including the protective sheet 200, the fixing unit 700, and the jig 100 are used.

  The electronic device 900 is an example of an electronic device to which a protective sheet is attached, and is, for example, a smartphone. In the present embodiment, the external shape of the electronic device 900 is a substantially rectangular parallelepiped, and specifically has a flat plate shape with rounded corners. On one surface 910 (also referred to as “front surface 910”) of two large substantially rectangular surfaces of the electronic device 900, a display surface 990 for displaying an image, a button 992, and a hole 994 for a speaker. And are provided. The display surface 990 is configured with a light-transmitting cover (for example, glass or hard plastic) that covers a display device (for example, a liquid crystal display) (not shown). The display surface 990 has a substantially rectangular shape. Electronic device 900 also includes a touch panel (not shown) for detecting a touch position on display surface 990.

  In the drawing, three directions X, Y, and Z which are directions with respect to the electronic device 900 and perpendicular to each other are shown. The X direction is a direction parallel to the long side of the front surface 910. The Y direction is a direction parallel to the short side of the front surface 910. The Z direction is a direction perpendicular to the front surface 910 and is a direction toward the front surface 910 when viewed from the electronic device 900. Hereinafter, the Z direction is also referred to as “+ Z direction”, and the Z direction side is also referred to as “+ Z side”. The direction opposite to the Z direction is also referred to as “−Z direction”, and the −Z direction side is also referred to as “−Z side”. The same applies to the X direction and the Y direction.

  In the drawing, the directions of the first composite sheet 600, the fixing portion 700, and the jig 100 are substantially the same as the directions when the protective sheet 200 is attached to the electronic device 900. Hereinafter, the structure of the 1st composite sheet 600, the fixing | fixed part 700, and the jig | tool 100 is demonstrated using the X, Y, Z direction of this state.

Accordingly, the display surface 990 corresponds to a portion of the outer surface of the electronic device 900 to which the protective sheet 200 is attached (hereinafter also referred to as “attachment target portion 900t” or simply “attachment portion 900t”).

  FIG. 2 is an explanatory diagram of the first composite sheet 600 including the protective sheet 200. 2A is a schematic cross-sectional view, FIG. 2B is a plan view viewed from the −Z direction, and FIG. 2C is a plan view viewed from the + Z direction. ing. In the first composite sheet 600, the release sheet 300, the protective sheet 200, and the cover sheet 400 are laminated in this order in the + Z direction, and the tab sheet 330 is fixed to the release sheet 300. Hereinafter, a composite sheet including a plurality of layers including a protective sheet is also referred to as a “protective sheet composite”. The protective sheet 200 includes a base material layer 210 and an adhesive layer 290 provided on the −Z side of the base material layer 210. A release sheet 300 for protecting the adhesive layer 290 is affixed to the −Z side surface of the adhesive layer 290. When the protective sheet 200 is attached to the electronic device 900 (FIG. 1), the release sheet 300 is removed from the adhesive layer 290, and the adhesive layer 290 is attached to the attaching portion 900t. Hereinafter, the remaining composite sheet after the release sheet 300 and the tab sheet 330 are removed from the first composite sheet 600, that is, the composite sheet including the protective sheet 200 and the cover sheet 400 is also referred to as a second composite sheet 620.

  In this embodiment, the outer shape of the release sheet 300 is slightly larger than that of the protective sheet 200. As shown in FIG. 2B, in the state of being attached to the protective sheet 200, the release sheet 300 includes a part having the same shape as the protective sheet 200 and a part 310 protruding from the −X side of the protective sheet 200. I have. The protruding portion 310 forms an edge on the −X side of the release sheet 300 (hereinafter referred to as “first peripheral edge 310”). The shape of the first peripheral edge portion 310 viewed in the −Z direction is a trapezoid whose bottom is the side 200 </ b> S having the same length that overlaps the −X side edge of the protective sheet 200. A portion of the end portion 332 of the tab sheet 330 that is folded back to the X side is fixed to the surface on the + Z side of the first peripheral edge portion 310. The length of the upper base of the trapezoid is the same as the width of the tab sheet 330. In the embodiment of FIG. 2B, the edges of the release sheet 300 in other directions (specifically, the three directions of + X, + Y, and −Y) are protected when attached to the protective sheet 200. It coincides with the edge of the sheet 200. However, the end of the release sheet 300 in at least one of these three directions may protrude outside the end of the protective sheet 200.

  The tab sheet 330 is a substantially rectangular belt-like sheet extending along the X direction. The width of the tab sheet 330 in the Y direction is narrower than the width of the release sheet 300 in the Y direction. On the other hand, the length of the tab sheet 330 in the X direction is longer than the length of the release sheet 300 in the X direction. The end portion 332 on the −X direction side of the tab sheet 330 is folded back at the −X side end of the first peripheral portion 310 of the release sheet 300, and is a predetermined length on the surface of the first peripheral portion 310 on the protective sheet 200 side. It extends and is fixed to the first peripheral edge 310 (for example, adhesion, welding, etc.). The tab sheet 330 forms a + X side edge of the release sheet 300 along the surface opposite to the protective sheet 200 side of the release sheet 300 from the end 332, that is, along the −Z side surface of the release sheet 300. 2 extends to the peripheral edge 320. The + X side end 334 of the tab sheet 330 protrudes beyond the second peripheral edge 320 beyond the second peripheral edge 320.

The cover sheet 400 includes a base material layer 410 and an adhesive layer 490 provided on the −Z side of the base material layer 410 and attached to the base material layer 210 of the protective sheet 200. The cover sheet 400 further includes a mark 430 attached to the + Z side surface of the base material layer 410. The mark 430 is used for positioning the protective sheet 200 with respect to the pasted portion 900t (FIG. 1). The mark 430 includes a base material layer 440 and an adhesive layer 450 provided on the −Z side of the base material layer 440 and attached to the base material layer 410. After the protective sheet 200 is pasted on the pasted portion 900t, the cover sheet 400 is removed from the protective sheet 200. In the present embodiment, the outline of the cover sheet 400 attached to the protective sheet 200 matches the outline of the protective sheet 200. However, a tab may be provided on the edge of the cover sheet 400 (for example, the base material layer 410) so that the cover sheet 400 can be easily peeled off.

  As each structure of the tab sheet 330, the protective sheet 200, the release sheet 300, and the cover sheet 400, various structures may be adopted. For example, the tab sheet 330 is formed of, for example, a resin (for example, PET) or paper, and the thickness thereof is, for example, 30 μm or more and 150 μm or less. The base material layer 210 of the protective sheet 200 is formed of a light-transmitting material (for example, PET (polyethylene terephthalate) or glass), and the thickness thereof is, for example, 50 μm or more and 200 μm or less. The release sheet 300 and the base material layer 410 of the cover sheet 400 are formed of a light-transmitting material (for example, PET), and the thickness thereof is, for example, 30 μm or more and 100 μm or less. The base material layer 440 of the mark 430 is formed of a colored material (for example, colored polyethylene) so that the shape of the mark 430 can be easily recognized visually, and the thickness thereof is, for example, 30 μm or more and 100 μm or less. . As each material of the adhesive layers 290, 490, 450, known adhesive materials having various translucency may be adopted.

  Note that having a light-transmitting property means that at least a part of light is transmitted in at least a part of a wavelength range of visible light (for example, 400 nm to 780 nm). When an object is placed on one side of a member and the object can be seen through the member from the opposite side of the member, the member is formed of a light-transmitting material (or the member has a light-transmitting property). Have).

  Each layer of the composite sheet may be composed of a plurality of layers stacked. For example, the base material layer 210 of the protective sheet 200 may include a PET layer and a glass layer laminated on the + Z side of the PET layer.

  The jig 100 (FIG. 1) forms a container that can accommodate the protective sheet 200 (and thus the first composite sheet 600). Specifically, the jig 100 includes a base wall portion 110 that is a substantially rectangular flat plate disposed substantially parallel to the pasting portion 900t, and a substantially vertical direction from the peripheral portion of the base wall portion 110 to the base wall portion 110 − A side wall portion 120 extending to the Z side and a flange portion 130 extending from the end portion on the −Z side of the side wall portion 120 to the outer peripheral side substantially parallel to the base wall portion 110 are provided. The side wall part 120 is provided over the entire periphery of the peripheral part of the base wall part 110 and surrounds the −Z side surface of the base wall part 110. The base wall part 110 and the side wall part 120 form a substantially rectangular parallelepiped container. The first composite sheet 600 is accommodated in this container. An opening 180 is formed at the center of the base wall 110. A portion 170 in the figure is an edge portion that forms the opening 180. A through hole 160 is formed in the + X side portion of the base wall 110. A portion 150 in the drawing is an edge portion that forms the through hole 160. The flange portion 130 is provided over the entire circumference of the end portion on the −Z side of the side wall portion 120.

  In this embodiment, the jig 100 is formed of a light-transmitting flexible material (for example, a resin such as polystyrene, PET, polyethylene, or polypropylene). The thickness of each element 110, 120, 130 is, for example, 50 μm or more and 1 mm or less. The jig 100 is formed using, for example, a mold (vacuum forming, press forming, injection molding, etc.).

  The fixing portion 700 is for detachably fixing the first composite sheet 600 to the surface on the −Z side of the base wall portion 110, and is a double-sided tape in this embodiment. FIG. 3 is a schematic cross-sectional view of the fixing portion 700. As shown in the drawing, the fixing portion 700 is formed by laminating a first adhesive layer 720, a base material layer 710, and a second adhesive layer 730 in this order in the Z direction. The first adhesive layer 720 on the −Z side is attached to the cover sheet 400 (specifically, the + Z side surface of the base material layer 410 (FIG. 2)). The second adhesive layer 730 on the + Z side is attached to the −Z side surface of the base wall portion 110 of the jig 100. Thus, the first composite sheet 600 is fixed to the surface on the −Z side of the base wall part 110 (the protective sheet 200 is fixed to the base wall part 110 via the cover sheet 400 and the fixing part 700. It can be said that). In addition, as a structure (for example, each material of each layer 710,720,730) of the fixing | fixed part 700, you may employ | adopt well-known various structures. The fixing unit 700 is used for attaching the protective sheet 200 together with the jig 100. Accordingly, it can be said that the entire jig 100 and the fixing portion 700 are jigs for attaching the protective sheet 200.

  FIG. 4 is a schematic diagram of an example of a package including the jig 100, the fixing unit 700, and the first composite sheet 600. In the package 2000, the first composite sheet 600 is fixed to the jig 100 by the fixing portion 700. In the figure, a perspective view of the package 2000 is shown. 4A shows a perspective view seen from the + Z side, as in FIG. 1, and FIG. 4B shows a perspective view seen from the −Z side. FIG. 5 is a cross-sectional view of the package 2000. 5A shows an AA cross section (cross section perpendicular to the Y direction) in FIG. 4, and FIG. 5B shows a BB cross section (cross section perpendicular to the X direction) in FIG. Yes.

  As shown in FIGS. 5A and 5B, the first composite sheet 600 is fixed to the first surface 111 that is the −Z side surface of the base wall portion 110 via the fixing portion 700. (Hereinafter, the surface on the + Z side of the base wall portion 110 is also referred to as the second surface 112).

  As shown in FIGS. 4B, 5A, and 5B, the end portion 122 on the −Z side of the side wall portion 120 forms a rectangular opening 190 that is substantially the same as the base wall portion 110. ing. In FIG. 5A, the length Hj is a length in a direction parallel to the long side 190L of the opening 190 (FIG. 4B). The length Hc is a length in a direction parallel to the long side of the protective sheet 200. Here, Hj> Hc. In FIG. 5B, the length Wj is a length in a direction parallel to the short side 190S of the opening 190 (FIG. 4B). The length Wc is a length in a direction parallel to the short side of the protective sheet 200. Here, Wj> Wc. The opening 190 (and hence the base wall portion 110) is larger than the protective sheet 200, the release sheet 300, and the cover sheet 400. The entire protective sheet 200, release sheet 300, and cover sheet 400 are disposed in a region surrounded by the side wall 120.

  As shown in FIG. 5A, the through-hole 160 of the base wall portion 110 is located on the outer peripheral side (here, + X side) of the second peripheral edge portion 320 of the release sheet 300. The + X side end portion 334 of the tab sheet 330 protrudes out of the jig 100 through the through hole 160. The width Wp shown in FIG. 4A is the width of the through hole 160 in the Y direction. The width Wp of the through hole 160 is larger than the length Wc of the protective sheet 200 in the Y direction. In this embodiment, the width of the release sheet 300 in the Y direction is the same as the width Wc. That is, when viewing the release sheet 300 from the through hole 160, the width Wp of the through hole 160 is larger than the width of the release sheet 300. In the present embodiment, the through hole 160 extends in the Y direction. Therefore, the width Wp is the width of the through hole 160 in the longitudinal direction (here, the Y direction). And the width Wp of the longitudinal direction of the through-hole 160 is larger than the width Wc of the same direction (here Y direction) as the longitudinal direction of the through-hole 160 of the peeling sheet 300. FIG. As will be described later, the release sheet 300 is taken out of the jig 100 through the through hole 160.

  As shown in FIG. 4A, the mark 430 is located in the opening 180 of the base wall portion 110. The user can easily confirm the position of the mark 430, that is, the position of the protective sheet 200 through the opening 180.

  Such a package 2000 may be provided by the manufacturer. Note that a sheet (not shown) that closes the opening 190 may be attached to the surface on the −Z side of the flange portion 130 of the jig 100 (a package in which the opening 190 is closed is also called a blister package). Further, the package 2000 may be provided in a state of being accommodated in a bag (not shown). In addition, the first composite sheet 600 is not fixed to the base wall part 110, and the fixing part 700 and the first composite sheet 600 are accommodated in an area surrounded by the base wall part 110 and the side wall part 120. A package may be provided.

  When the protective sheet 200 is attached to the electronic device 900, the jig 100 is put on the electronic device 900. FIG. 6 is a perspective view showing how the jig 100 is arranged with respect to the electronic apparatus 900. Electronic device 900 is placed on flat table 1000. At this time, the surface on the opposite side of the front surface 910 is placed on the flat table 1000, and the front surface 910 (and thus the pasted portion 900t) is exposed.

  Further, by operating the electronic device 900, a positioning mark 980 having a shape corresponding to the mark 430 of the first composite sheet 600 is displayed on the display surface 990 of the electronic device 900. In this embodiment, the mark 980 includes a first line segment 981 parallel to the long side of the display surface 990 and a second line segment 982 parallel to the short side. These line segments 981 and 982 are arranged so as to intersect at the center of the display surface 990. Such a positioning mark 980 specifies, for example, the length of the long side (for example, the number of pixels) and the length of the short side of the display surface 990, and is approximately at the center between the specified long side and short side. More preferably, it is formed by drawing line segments 981 and 982 at the center. The display of the positioning mark 980 is realized by, for example, an application program (not shown) that operates on the electronic device 900. Even when the touch panel detects the touch position by touching the display surface 990 (even indirectly) when the protective sheet 200 is applied, the positioning mark 980 is displayed on the display surface 990. The display is preferably maintained without being changed (moved, enlarged, reduced, erased, etc.).

  In a state where the first composite sheet 600 is fixed to the jig 100 by the fixing portion 700, the electronic apparatus 900 is covered with the jig 100. At this time, the orientation of the jig 100 is adjusted so that the long side 190L of the opening 190 (FIG. 4B) is substantially parallel to the X direction and the short side 190S is substantially parallel to the Y direction.

  FIG. 7 is a cross-sectional view of the electronic device 900 and the jig 100 placed on the electronic device 900. In this embodiment, the opening 190 formed by the end portion 122 of the side wall portion 120 is larger than the electronic device 900, and the entire electronic device 900 is disposed in a region surrounded by the side wall portion 120. And the base wall part 110 has covered the whole sticking part 900t.

  An end portion 122 on the −Z side of the side wall portion 120 forms an end surface 122s on the −Z side. The end surface 122s is a portion facing the −Z side (specifically, the −Z direction) of the outer surface of the side wall portion 120. The end surface 122s is an example of a surface facing away from the base wall 110, and is substantially parallel to the base wall 110 in this embodiment. The end surface 122s forms an edge of the opening 190, and is placed on a portion of the flat table 1000 around the electronic device 900.

  The side wall part 120 can support the base wall part 110 in a state of covering the entire pasted part 900 t with respect to the flat base 1000 (and thus the electronic device 900) by having the end surface 122 s placed on the flat base 1000. Hereinafter, a state in which the base wall portion 110 is supported at a position covering the entire pasted portion 900t is also referred to as a “cover state”.

  In FIG. 7A, the thickness T1 is the thickness of the protective sheet 200. The distance T2 is the first surface 111 of the base wall portion 110 and the -Z side surface of the first composite sheet 600 (here, the -Z side surface of the tab sheet 330 in contact with the release sheet 300). The maximum distance between. The distance T3 is the shortest distance between the first surface 111 of the base wall portion 110 and the pasted portion 900t of the electronic device 900. In the present embodiment, the side wall 120 is configured to satisfy T3> T1, and further configured to satisfy T3> T2 (for example, the length of the side wall 120 in the Z direction is an electron This is larger than the sum of the thickness of the device 900 in the Z direction and the thickness of the first composite sheet 600 in the Z direction). Here, the difference between the distance T3 and the distance T2, that is, the size of the gap between the first composite sheet 600 and the pasted portion 900t is larger than the sum of the thickness of the release sheet 300 and the thickness of the tab sheet 330. This is because the tab sheet 330 and the release sheet 300 are integrally removed through this gap.

  FIG. 8 is a schematic diagram illustrating a state where the release sheet 300 is peeled off. In the drawing, a cross section perpendicular to the Y direction is shown. Peeling of the release sheet 300 proceeds in the order of FIG. 8 (A) to FIG. 8 (D). First, as shown in FIG. 8A, the user pulls the end 334 of the tab sheet 330 in a direction away from the protective sheet 200 (here, the + X direction). As a result, the entire tab sheet 330 moves to the + X side. Since the tab sheet 330 is located on the −Z side of the release sheet 300, the folded end portion 332 of the tab sheet 330 is pulled to the −Z side of the release sheet 300, and the first peripheral edge 310 of the release sheet 300. Is bent to the -Z side. When the tab sheet 330 is further pulled in the + X direction, as shown in FIG. 8B, the first peripheral edge 310 of the release sheet 300 is folded back and moved in the + X direction. Note that bending and folding the first peripheral edge 310 of the release sheet 300 is performed using a gap between the electronic device 900 and the side wall 120. Therefore, as compared with the case where the first peripheral edge 310 of the release sheet 300 is folded back in the gap above the pasting portion 900t, the shortest distance T3 (FIG. 7A) between the base wall portion 110 and the pasting portion 900t is smaller. It may be small.

  When the tab sheet 330 is further pulled in the + X direction, the folded portion 308 of the release sheet 300 gradually moves toward the through hole 160 as shown in FIG. The portion on the −X side is peeled off from the adhesive layer 290 of the protective sheet 200. Further, the first peripheral edge 310 of the release sheet 300 is pulled by the tab sheet 330 and moves out of the through hole 160. When the tab sheet 330 is further pulled in the + X direction, the entire release sheet 300 is peeled from the protective sheet 200 as shown in FIG. Then, the entire release sheet 300 is removed from the jig 100 through the through hole 160.

  By peeling off the release sheet 300, the adhesive layer 290 of the protective sheet 200 is exposed. The exposed adhesive layer 290 (and thus the protective sheet 200) is surrounded by the base wall part 110 and the side wall part 120. Therefore, it is possible to prevent foreign matters such as dust from adhering to the adhesive layer 290 of the protective sheet 200.

  In this way, the release sheet 300 and the tab sheet 330 are removed through the gap between the pasting portion 900t and the first composite sheet 600. Further, the release sheet 300 is peeled from the protective sheet 200 at the folded portion 308 (FIG. 8C). The direction of the force applied to the folded portion 308 is substantially the + X direction, and is substantially perpendicular to the −Z direction in which the protective sheet 200 (and thus the first composite sheet 600) is separated from the base wall 110 of the jig 100. . Generally, in order to peel a sheet affixed to the adhesive layer from the adhesive layer, a force for pulling the sheet away from the adhesive layer, that is, a force for pulling the sheet perpendicular to the adhesive layer is applied to the sheet. On the other hand, when a force parallel to the adhesive layer is applied to the sheet, the component of the force for peeling the sheet (that is, the component perpendicular to the adhesive layer) is small, and thus the sheet is hardly peeled off. As described above, the direction of the force applied to the folded portion 308 of the release sheet 300 is substantially the + X direction, and the fixing portion 700 (specifically, the adhesive layers 720 and 730 of the fixing portion 700 (FIG. 3)). Is roughly parallel to Therefore, it can suppress that the 1st composite sheet 600 remove | deviates from the base wall part 110 resulting from peeling of the peeling sheet 300. FIG.

  FIG. 8D shows the thickness T4. The thickness T4 is the thickness of the second composite sheet 620 in a state where the release sheet 300 is peeled off. As shown in the figure, the shortest distance T3 between the first surface 111 of the base wall 110 and the affixed portion 900t of the electronic device 900 is greater than the thickness T4. Thus, the jig 100 can support the second composite sheet 620 at a position away from the pasting portion 900t in the cover state. In addition, as shown in FIGS. 7A and 7B, there is a gap between the electronic device 900 and the side wall 120 over the entire circumference. Specifically, in FIG. 7A, the length Hd is the length of the electronic device 900 in the X direction. In this embodiment, Hj> Hd> Hc. In FIG. 7B, the length Wd is the length of the electronic device 900 in the Y direction. In this embodiment, Wj> Wd> Wc. Therefore, by moving the jig 100 without moving the electronic device 900 on the flat table 1000, the second composite sheet 620 (and thus the protective sheet 200) can be moved in a direction parallel to the pasting portion 900t. Thus, the position of the protective sheet 200 with respect to the pasting portion 900t (particularly, the position and orientation in the direction parallel to the pasting portion 900t) can be adjusted.

  FIG. 9 is a schematic diagram of position adjustment. FIG. 9A is an explanatory diagram of the mark 430. In the figure, the jig 100 and the second composite sheet 620 in a plan view with respect to the protective sheet 200 (that is, viewed in a direction perpendicular to the protective sheet 200) are shown. The mark 430 has two first-type vertices 431 arranged in a direction parallel to the long side of the protective sheet 200 and two second-type vertices 432 arranged in a direction parallel to the short side. These vertices 431 and 432 are both formed by the pointed portion of the triangular tip of the mark 430. The two first-type vertices 431 are assumed to overlap the first line segment 981 described in FIG. It is assumed that the two second-type vertices 432 overlap the second line segment 982. When the vertices 431 and 432 overlap the line segments 981 and 982, the position of the mark 430 with respect to the protective sheet 200 is determined in advance so that the position of the protective sheet 200 with respect to the pasted portion 900t is appropriate.

  FIG. 9B and FIG. 9C are schematic views of the electronic device 900 and the jig 100 placed on the electronic device 900 in a plan view with respect to the protective sheet 200. In FIG. 9B, the position of the second composite sheet 620 is shifted with respect to the pasted portion 900t. In FIG. 9C, the vertices 431 and 432 overlap the line segments 981 and 982, respectively, and the position of the second composite sheet 620 with respect to the pasted portion 900t is appropriate.

  In the present embodiment, since the protective sheet 200 and the cover sheet 400 are formed of a light-transmitting material, the user is in a state where the second composite sheet 620 is disposed above (+ Z side) the pasting portion 900t. Thus, the line segments 981 and 982 can be visually recognized through the second composite sheet 620. Therefore, the user can easily confirm whether or not the vertices 431 and 432 overlap the line segments 981 and 982, respectively. In addition, since the mark 430 is disposed in the opening 180 of the jig 100 in a plan view with respect to the protective sheet 200, the user can easily visually recognize the apexes 431 and 432 and the line segments 981 and 982 through the opening 180. .

  Moreover, the base wall part 110 of the jig | tool 100 is formed with the material which has translucency. Therefore, the user can visually recognize the position of the protective sheet 200 with respect to the pasted portion 900 t through the base wall 110.

  As described with reference to FIG. 7, the user can adjust the position of the second composite sheet 620 with respect to the pasted portion 900 t by moving the jig 100 on the flat table 1000. Thereby, the user can move the second composite sheet 620 arranged at an inappropriate position as shown in FIG. 9B to an appropriate position as shown in FIG. 9C.

  FIG. 10 is a schematic diagram illustrating a state where the protective sheet 200 is pasted on the pasting portion 900t after the position adjustment. In the drawing, a cross section perpendicular to the Y direction is shown. The application of the protective sheet 200 proceeds in the order of FIG. 10 (A), FIG. 10 (B), and FIG. 10 (C). As shown in FIG. 10A, the user presses the second composite sheet 620 toward the pasting portion 900t with a finger or the like through the opening 180. Thereby, the 2nd composite sheet 620 remove | deviates from the fixing | fixed part 700, and a part of adhesion layer 290 of the protection sheet 200 adheres to the sticking part 900t. At this time, as described in FIG. 9C, the position of the second composite sheet 620 with respect to the pasting portion 900t (particularly, the position in the direction parallel to the pasting portion 900t) has been adjusted to an appropriate position. Therefore, the adhesive layer 290 of the protective sheet 200 can contact an appropriate position on the pasted portion 900t.

  Moreover, the base wall part 110 and the side wall part 120 are formed of a flexible material. Therefore, when the base wall part 110 and the side wall part 120 are deformed, the user can easily press the second composite sheet 620 against the pasted portion 900t. For example, the base wall portion 110 can be bent so that the portion to which the fixing portion 700 is attached approaches the electronic device 900. Further, the side wall 120 can be bent so that the connection portion with the base wall 110 approaches the electronic device 900. Therefore, the second composite sheet 620 can be brought close to the pasting portion 900 t in a state of being fixed to the base wall portion 110. As a result, the accuracy of the sticking position of the protective sheet 200 with respect to the sticking portion 900t can be improved.

  In the present embodiment, the adhesive force of the second adhesive layer 730 of the fixing portion 700 is stronger than the adhesive force of the first adhesive layer 720. Thereby, it is suppressed that the fixing | fixed part 700 peels from the base wall part 110. FIG. For example, as the material of the second adhesive layer 730, a material having a stronger adhesive force than the material of the first adhesive layer 720 is employed. However, the fixing part 700 may be removed from the base wall part 110 and remain on the second composite sheet 620.

  Next, as shown in FIG. 10B, the jig 100 is removed from the flat table 1000. And a user sticks the whole protective sheet 200 on the sticking part 900t by pressing the 2nd composite sheet 620 on the sticking part 900t. At this time, it is preferable not to generate air bubbles between the affixed portion 900 t and the protective sheet 200. For example, as described with reference to FIG. 10A, a method may be adopted in which a part of the protective sheet 200 is brought into contact with the pasting portion 900 t and then the contact portion is widened to expel bubbles from the periphery of the protective sheet 200. Good.

  After the entire protective sheet 200 is attached to the attaching portion 900t, the cover sheet 400 is removed from the protective sheet 200 as shown in FIG. Thus, the application of the protective sheet 200 is completed.

  As described above, in the first embodiment, the base wall portion 110 of the jig 100 includes the edge portion 150 that forms the through hole 160 for removing the tab sheet 330 and the release sheet 300. As shown in FIGS. 4 and 5, the through hole 160 is located on the outer peripheral side of the second peripheral edge 320 of the release sheet 300 when the first composite sheet 600 is fixed to the base wall 110. As described with reference to FIG. 4A, the through-hole 160 has a width Wc (here, the first peripheral edge 310 (FIG. 4A)) toward the through-hole 160 in the + X direction of the release sheet 300. The width Wp is larger than the vertical width Wc in the Y direction (FIG. 4A). That is, when viewing the release sheet 300 from the through hole 160, the through hole 160 has a width Wp that is greater than the width Wc of the release sheet 300. Further, as described above, the width Wp is the width of the through hole 160 in the longitudinal direction (here, the Y direction). The width Wp is larger than the width Wc of the release sheet 300 in the same direction (here, the Y direction). Therefore, as described with reference to FIG. 8, by pulling the end portion 334 of the tab sheet 330 from the outside of the through hole 160, the release sheet 300 is peeled off from the protection sheet 200 without removing the protection sheet 200 from the base wall portion 110. Can do. Then, the peeled release sheet 300 can be taken out of the space surrounded by the base wall part 110 and the side wall part 120 through the through hole 160. Even when the release sheet 300 is removed from the protective sheet 200, the protective sheet 200 is surrounded by the base wall part 110 and the side wall part 120, so that dust or the like is present on the adhesive layer 290 of the protective sheet 200. It can suppress that the foreign material adheres.

  8D, in the cover state, the shortest distance T3 between the pasting portion 900t and the first surface 111 of the base wall portion 110 is larger than the thickness T4 of the second composite sheet 620. large. Therefore, the jig 100 can support the second composite sheet 620 at a position away from the pasting portion 900t in the cover state. Further, in the present embodiment, the base wall portion 110 has an opening 180 that overlaps the pasted portion 900t and the protective sheet 200 in the cover state. Moreover, the base wall part 110 is formed with the material which has translucency. Therefore, the user can easily confirm the position of the protective sheet 200 with respect to the electronic device 900 through the opening 180 and the base wall 110 before the protective sheet 200 is attached.

  Further, as described with reference to FIG. 4B, the side wall part 120 forms an opening 190 facing the side opposite to the base wall part 110 side. As described with reference to FIG. 7, the opening 190 is larger than the electronic device 900. In the cover state, the entire end surface 122 s that forms the edge of the opening 190 of the side wall 120 is placed on a portion of the flat table 1000 around the electronic device 900. As described above, the protective sheet 200 after the release sheet 300 is peeled is located in a space surrounded by the base wall part 110, the side wall part 120, the electronic device 900, and the flat base 1000 of the jig 100. Yes. Therefore, the position of the protective sheet 200 with respect to the electronic device 900 can be confirmed before sticking while suppressing the adhesion of foreign matters such as dust to the adhesive layer 290 of the protective sheet 200. And it can suppress that dust infiltrates from the exterior of the jig | tool 100 between the sticking part 900t and the protection sheet 200. FIG.

  Further, the edge portion 150 forming the through hole 160 used for taking out the release sheet 300 is provided in the base wall portion 110. Therefore, the through hole 160 can be easily formed. For example, what is necessary is just to form the through-hole 160 by punching out the part corresponding to the through-hole 160 of the jig | tool 100 before forming the through-hole 160 with a cutter.

B. Second embodiment:
FIG. 11 is an explanatory view showing another example of the release sheet. 11A and 11B are explanatory diagrams of the first composite sheet 600a including the release sheet 300a, and FIGS. 11C and 11D illustrate the first composite including the release sheet 300b. It is explanatory drawing of the sheet | seat 600b. 11A and 11C are plan views viewed from the −Z direction, and FIGS. 11B and 11D are plan views viewed from the + Z direction. . The only difference from the release sheet 300 shown in FIG. 2 is that the peripheral edge portions 310a and 310b to which the tab sheet 330 is fixed are different from the trapezoidal shape of the first peripheral edge portion 310 of the first embodiment. The structure of the other parts of the release sheets 300a and 300b is the same as the structure of the corresponding part of the release sheet 300 of the first embodiment (the same parts as the corresponding parts are denoted by the same reference numerals, (Omitted). The tab sheet 330, the protective sheet 200, and the cover sheet 400 are the same as those in the first embodiment.

  11A and 11B includes a portion having the same shape as that of the protective sheet 200 and a first peripheral edge portion 310a that protrudes from the −X side of the protective sheet 200. The shape of the first peripheral edge portion 310 a viewed in the −Z direction is a substantially rectangular shape that overlaps the tab sheet 330. Thus, the width of the first peripheral edge 310a in the Y direction perpendicular to the −X direction from which the first peripheral edge 310a protrudes may be narrower than the width of the protective sheet 200. Also in this case, the release sheet 300a can be detached from the protective sheet 200 by pulling the tab sheet 330, as in the embodiment of FIG.

  The release sheet 300b in FIGS. 11C and 11D includes a portion having the same shape as the protective sheet 200, and a first peripheral edge 310b protruding from the −X side of the protective sheet 200. The shape of the first peripheral edge portion 310b viewed in the −Z direction is a substantially rectangular shape having the same width as the protective sheet 200 (this width is Y perpendicular to the −X direction in which the first peripheral edge portion 310b protrudes). Direction width). The shape of the release sheet 300b is a substantially rectangular shape obtained by extending the shape of the protective sheet 200 in the −X direction. As described above, the width of the portion connected to the tab sheet 330 of the first peripheral edge 310 b may be larger than the width of the tab sheet 330. Also in this case, the release sheet 300b can be detached from the protective sheet 200 by pulling the tab sheet 330, as in the embodiment of FIG.

  Note that the release sheet 300a and the release sheet 300b may be applied to other examples described later.

C. Third embodiment:
FIG. 12 is an explanatory diagram of another embodiment of the jig. For the jig 100b of the third embodiment, the release sheet 300a shown in FIGS. 11A and 11B is used. There are two differences from the jig 100 of the first embodiment (FIGS. 7A and 7B). The first difference is that in the jig 100b of the third embodiment, the base wall portion 110b is smaller than the electronic device 900, and the opening 190b formed by the side wall portion 120b is smaller than the electronic device 900. The second difference is that a notch 128 for protruding the tab sheet 330 and the first peripheral edge 310a of the release sheet 300a is formed in the portion of the side wall 120b that forms the outer peripheral surface on the −X side. is there. The structure of the other part of the jig 100b is the same as the structure of the corresponding part of the jig 100 of the first embodiment (the same part as the corresponding part is denoted by the same reference numeral and the description thereof is omitted). ). The procedure for attaching the protective sheet 200 is the same as that of the first embodiment except that the position of the protective sheet 200 is adjusted by moving the jig 100b relative to the electronic device 900.

  FIG. 12A is a perspective view showing a state in which the first composite sheet 600a is fixed to the jig 100b. 12 (B) and 12 (C) are cross-sectional views showing cover states similar to those in FIGS. 7 (A) and 7 (B), respectively. The base wall 110 b is a substantially rectangular flat plate that is slightly smaller than the front surface 910 of the electronic device 900. The side wall 120b extends from the peripheral edge of the base wall 110b to the −Z side substantially perpendicular to the base wall 110b. The side wall part 120b is provided over substantially the entire circumference of the peripheral edge part of the base wall part 110b, and surrounds the first surface 111b of the base wall part 110b. The base wall part 110b and the side wall part 120b form a substantially rectangular parallelepiped container. The first composite sheet 600a is accommodated in the container and fixed to the first surface 111b of the base wall portion 110b by the fixing portion 700, as in the above embodiments. The flange portion 130b extends from the −Z side end portion 122b of the side wall portion 120b to the outer peripheral side substantially parallel to the base wall portion 110b. The flange portion 130b is provided over the entire end portion 122b.

  The end surface 122bs formed by the −Z side end portion 122b of the side wall portion 120b is an example of a surface facing in a direction away from the base wall portion 110b, and is substantially parallel to the base wall portion 110b in the present embodiment. The end surface 122bs forms the edge of the opening 190b. Then, the entire end surface 122bs is placed not on the flat base 1000 but on a portion around the pasted portion 900t in the front surface 910 of the electronic device 900.

  In FIG. 12B, the length Hj is a length in a direction parallel to a long side (not shown) of the opening 190b. In this embodiment, Hd> Hj> Hc. In FIG. 12C, the length Wj is a length in a direction parallel to a short side (not shown) of the opening 190b. In this embodiment, Wd> Wj> Wc. Thus, the opening 190b and the base wall portion 110b are larger than the pasting portion 900t and smaller than the electronic device 900.

  The side wall part 120b can support the base wall part 110b in the state which covers the whole sticking part 900t with respect to the electronic device 900, when the end surface 122bs mounts on the front surface 910. FIG. In the present embodiment, the state of FIGS. 12B and 12C in which the base wall portion 110b is supported at a position covering the entire pasting portion 900t in this way corresponds to the “cover state”.

  In FIG. 12B, the thickness T1, the distance T2, and the distance T3 are the same as those in the embodiment of FIG. Thus, the jig 100b supports the first composite sheet 600a at a position away from the pasting portion 900t in the cover state.

  In the present embodiment, the base wall portion 110b includes an edge portion 150 that forms the same through-hole 160 as in the embodiments of FIGS. The through hole 160 is located on the outer peripheral side (here, the + X side) of the second peripheral edge portion 320a on the + X side of the release sheet 300a. The + X side end 334 of the tab sheet 330 protrudes out of the jig 100 b through the through hole 160. The −X side end 332 of the tab sheet 330 and the first peripheral edge 310 a of the release sheet 300 protrude out of the jig 100 b through the notch 128 of the side wall 120 b. When the user pulls the end 334 of the tab sheet 330 in the direction away from the protective sheet 200 (here, the + X direction), the first peripheral edge of the release sheet 300a is the same as in FIGS. 8A and 8B. The portion 310a is bent toward the −Z side and then folded back toward the + X side. Bending and bending the first peripheral edge 310a is performed outside the jig 100b. Accordingly, the shortest distance T3 between the base wall portion 110 and the pasting portion 900t may be smaller than when the first peripheral edge 310a of the release sheet 300a is folded back in the gap above the pasting portion 900t. When the tab sheet 330 is further pulled in the + X direction, the release sheet 300 is peeled off from the protective sheet 200 as in FIG. 8C and FIG. Removed.

  In the present embodiment, the base wall portion 110b forms the same opening 180 as the opening 180 in FIG. The mark 430 of the second composite sheet 620 is located in the opening 180 of the base wall portion 110b. The user can visually recognize the mark 430 and the mark 980 displayed on the display surface 990 of the electronic device 900 through the opening 180 as in the embodiment of FIGS. 9B and 9C. Further, the user can move the jig 100b on the front surface 910 in a direction parallel to the pasting portion 900t. Therefore, the user can adjust the position of the protective sheet 200 with respect to the pasting portion 900t with high accuracy, as in the embodiments of FIGS. 9B and 9C. The attachment of the protective sheet 200 after the position adjustment is performed in the same manner as in the embodiment of FIG.

  Thus, the side wall part 120b forms the opening 190b facing the opposite side to the base wall part 110b. The opening 190b is smaller than the electronic device 900 and larger than the pasting portion 900t. In the cover state, the entire end surface 122bs forming the edge of the opening 190b of the side wall portion 120b is placed on a portion around the pasting portion 900t of the front surface 910 of the electronic device 900. Thus, the protective sheet 200 after the release sheet 300a is peeled is located in a space surrounded by the base wall part 110b, the side wall part 120b, and the electronic device 900 of the jig 100b. Therefore, the position of the protective sheet 200 with respect to the electronic device 900 can be confirmed before sticking while suppressing the adhesion of foreign matters such as dust to the adhesive layer 290 of the protective sheet 200. And it can suppress that dust infiltrates from the exterior of the jig | tool 100b between the sticking part 900t and the protection sheet 200. FIG.

  In the present embodiment, the base wall portion 110b has an opening 180 that overlaps the pasting portion 900t and the protective sheet 200 in the cover state. Moreover, the base wall part 110b is formed with the material which has translucency. Therefore, the user can easily confirm the position of the protective sheet 200 with respect to the electronic device 900 through the opening 180 and the base wall portion 110b.

D. Fourth embodiment:
FIG. 13 is an explanatory diagram of another example of the composite sheet and the jig. FIG. 13A illustrates the electronic device 900 viewed from the −Z direction. The pasted portion 900tc of this embodiment is a substantially rectangular area including a button 992 and a hole 994 located outside the display surface 990 in addition to the display surface 990. FIG. 13B shows the protective sheet 200c viewed in the −Z direction. In the protective sheet 200c, a first hole 202 corresponding to the button 992 of the electronic device 900 and a second hole 204 corresponding to the hole 994 of the electronic device 900 are formed. The shape of the first hole 202 is the same shape as the button 992 or slightly larger than that. The shape of the second hole 204 is the same shape as the hole 994 or slightly larger than that. With the outline of the first hole 202 approximately overlapping the outline of the button 992 and the outline of the second hole 204 approximately overlapping the outline of the hole 994, the position of the protective sheet 200c relative to the application portion 900tc is appropriate. The positions and shapes of the holes 202 and 204 of the protective sheet 200 are determined in advance.

  FIGS. 13C and 13D are perspective views of the jig 100c and the first composite sheet 600c of this embodiment. FIG. 13C shows a state before the first composite sheet 600c is fixed to the jig 100c, and FIG. 13D shows a state where the first composite sheet 600c is fixed to the jig 100c. . In the first composite sheet 600c of this example, the release sheet 300c, the protective sheet 200c (FIG. 13B), and the cover sheet 400c are laminated in this order toward the + Z direction, and the tab sheet 330 is formed on the release sheet 300c. Is fixed.

  The outer shape of the cover sheet 400c is substantially the same as the outer shape of the protective sheet 200c. In this embodiment, the cover sheet mark 430 (FIG. 1) is omitted. The display of the mark 980 (FIG. 6) by the electronic device 900 is also omitted. This is because, as will be described later, in this embodiment, the protective sheet 200c is appropriately positioned by fitting the jig 100c to the electronic device 900 without using the mark 430. The release sheet 300c includes a portion having the same shape as that of the protective sheet 200c, and a first peripheral portion 310c that is the same as the first peripheral portion 310a of FIG. The tab sheet 330 is fixed to the first peripheral edge portion 310c. In this embodiment, through holes 602 and 604 each including the holes 202 and 204 described with reference to FIG. 13B are formed in the stacked layers 300c, 200c, and 400c. The configuration other than the above-described portion of the first composite sheet 600c is the same as the configuration of the corresponding portion of the first composite sheet 600 described with reference to FIG.

  The jig 100c has a base wall portion 110c whose contour shape when viewed in the -Z direction is substantially the same as the contour shape of the electronic device 900, and the peripheral edge portion of the base wall portion 110c to the base wall portion 110c. And a side wall 120c extending substantially vertically to the −Z side. Unlike the jigs of the above embodiments, the flange portion (for example, the flange portion 130 in FIG. 1) and the opening 180 are omitted. The side wall 120c surrounds the first surface 111c on the −Z side of the base wall 110c. An end portion 122c on the −Z side of the side wall portion 120c forms an opening 190c having substantially the same shape as the base wall portion 110c. A notch 128c is formed in a portion on the −X side of the side wall 120c. Similar to the notch 128 of FIG. 12, the notch 128c is formed so that the first peripheral edge 310c of the release sheet 300c and the end 332 of the tab sheet 330 protrude.

  In addition, the base wall portion 110c includes two projecting portions 118 and 119 that project in the −Z direction from the first surface 111c. The first protrusion 118 corresponds to the through hole 602 of the first composite sheet 600c, and the second protrusion 119 corresponds to the through hole 604 of the first composite sheet 600c. In this embodiment, when viewed in the + Z direction, the shape of the first protrusion 118 is approximately the same as the shape of the corresponding through hole 602, and the shape of the second protrusion 119 is the corresponding hole 604. The shape is roughly the same. As shown in FIG. 13D, when the first composite sheet 600c is fixed to the first surface 111c of the base wall portion 110c, the first protrusion 118 is inserted into the through hole 602 and the second protrusion 119 is a hole. 604 is inserted. In this state, the outer peripheral surface of the first protrusion 118 is in contact with the inner peripheral surface of the through hole 602, and the outer peripheral surface of the second protrusion 119 is in contact with the inner peripheral surface of the hole 604. As a result, the first composite sheet 600 c is fixed to the base wall portion 110 without detaching from the protruding portions 118 and 119 of the base wall portion 110.

  Moreover, the base wall part 110c is provided with the edge part 150 which forms the through-hole 160 located in the part of the + X side of the base wall part 110c. When the first composite sheet 600c is fixed to the base wall portion 110c, the through-hole 160 is located on the outer peripheral side (here, the + X side) of the second peripheral portion 320c on the + X side of the release sheet 300c. . 13C and 13D, the tab sheet 330 is shown far away from the release sheet 300c in order to make the through holes 602 and 604 and the protrusions 118 and 119 easier to see. Actually, although not shown, the tab sheet 330 extends from the first peripheral edge 310c to the second peripheral edge 320c on the −Z side surface of the release sheet 300c as in the embodiment of FIG. , Protruding beyond the second peripheral edge 320c. The + X side end 334 of the tab sheet 330 protrudes out of the jig 100 c through the through hole 160.

  In the present embodiment, the jig 100c is formed of a light-transmitting flexible material in the same manner as the jig described above. Such a jig 100c is formed by using, for example, a forming die (vacuum forming, press forming, injection molding, etc.).

  FIG. 14 is a cross-sectional view of the electronic device 900 and the jig 100c placed on the electronic device 900. FIG. 14A shows a cross section passing through the protrusions 118 and 119 and perpendicular to the Y direction, and FIG. 14B shows a cross section passing through the protrusion 119 and perpendicular to the X direction. An end portion 122c on the −Z side of the side wall portion 120c forms an end surface 122cs on the −Z side. The end face 122cs faces away from the base wall part 110c, and is substantially parallel to the base wall part 110c in this embodiment. The end surface 122cs forms an edge of the opening 190c and is placed on a portion of the flat table 1000 around the electronic device 900. In this state, the side wall portion 120c can support the base wall portion 110c with respect to the electronic device 900 in a state of covering the entire pasted portion 900tc. In the present embodiment, the state of FIGS. 14A and 14B in which the base wall portion 110c is supported at a position covering the entire pasting portion 900tc in this way corresponds to the “cover state”.

  In this embodiment, in the cover state, the electronic device 900 is fitted into the opening 190c of the jig 100c. The length Hj in FIG. 14A is a length in a direction parallel to the long side 190cL of the opening 190c (FIG. 13D). In the present embodiment, the length Hj of the opening 190c is substantially the same as the length Hd of the electronic device 900. A length Wj in FIG. 14B is a length in a direction parallel to the short side 190cS of the opening 190c (FIG. 13D). In the present embodiment, the length Wj of the opening 190c is substantially the same as the length Wd of the electronic device 900.

  The inner peripheral surface 127 of the side wall 120c is in contact with the edge of the electronic device 900 over substantially the entire periphery. As a result, the position of the jig 100c with respect to the electronic device 900 (in particular, the position in the direction parallel to the pasted portion 900tc) is determined. In such a cover state, the positions of the protruding portions 118 and 119 of the base wall portion 110c are so as to face the button 992 and the hole 994 of the electronic device 900, that is, the position of the protective sheet 200c with respect to the pasted portion 900tc is appropriate As such, it is predetermined. As a result, by placing the jig 100c on the electronic device 900 in a state where the first composite sheet 600c is fixed to the base wall portion 110c, the jig 100c causes the protective sheet 200c to be appropriately attached to the affixed portion 900tc. Can support in position.

  The −X side end 332 of the tab sheet 330 and the first peripheral edge 310c of the release sheet 300c protrude out of the jig 100c through the cutout 128c of the side wall 120c. When the user pulls the end portion 334 of the tab sheet 330, the release sheet 300c is removed from the protective sheet 200c. The release sheet 300c is removed in the same manner as in the embodiment of FIG.

  After the release sheet 300c is removed, the protective sheet 200c is affixed to the affixed portion 900tc. In the present embodiment, the base wall part 110c and the side wall part 120c are formed of a flexible material. Therefore, although illustration is omitted, when the user presses the base wall portion 110c toward the sticking portion 900tc, the base wall portion 110c and the side wall portion 120c are deformed. For example, the base wall part 110 c can be bent so as to approach the electronic device 900. Moreover, the side wall part 120c can bend so that the connection part with the base wall part 110c may approach the electronic device 900. As a result, the protective sheet 200c is pressed against the pasted portion 900tc via the base wall portion 110c. In this way, the user can apply the protective sheet 200c to an appropriate position on the application portion 900tc by pressing the base wall portion 110c toward the application portion 900tc. In this embodiment, the display of the mark 980 on the display surface 990 of the electronic device 900 is omitted.

  When the user stops pressing the base wall portion 110c, the shape of the jig 100c returns to the original shape. Thereby, the composite sheet including the protective sheet 200c and the cover sheet 400c is detached from the protruding portions 118 and 119 of the base wall portion 110c. Thereafter, the jig 100c is removed from the electronic device 900, and the cover sheet 400c is removed from the protective sheet 200c. Thus, the application of the protective sheet 200c is completed.

  Thus, in the present embodiment, the portion on the inner peripheral side of the side wall portion 120c is in a relative position of the jig 100c with respect to the pasting portion 900tc by contacting the electronic device 900 in the cover state, and the pasting portion 900tc. The relative position in the direction parallel to is determined. Therefore, the position shift of the protective sheet 200c with respect to the electronic device 900 can be suppressed. And a user can stick protection sheet 200c in the suitable position on pasting part 900tc, without adjusting the position of protection sheet 200c.

  In this embodiment, the external shape of the electronic device 900 is a substantially rectangular parallelepiped. And the internal peripheral surface 127 of the side wall part 120c is four corners S1-S4 (FIG. 13 (A)) and four corners which form the edge of the electronic device 900 by planar view with respect to the sticking part 900tc in a cover state. The parts C1 to C4 are in contact with each other. Therefore, the jig 100c can appropriately determine the relative position of the jig 100c with respect to the electronic device 900. As a result, displacement of the position of the protective sheet 200c with respect to the electronic device 900 can be suppressed.

  In addition, as the shape of the protrusions 118 and 119, various other shapes can be adopted instead of the above shape. Generally, the shape of the first protrusion 118 is such that at least a part of the outer surface of the first protrusion 118 contacts the inner peripheral surface of the through hole 602 when the first protrusion 118 is inserted into the through hole 602. It is preferable to be configured. Similarly, the shape of the second protrusion 119 is such that when the second protrusion 119 is inserted into the hole 604, at least a part of the outer surface of the second protrusion 119 contacts the inner peripheral surface of the hole 604. It is preferable to be configured.

E. Another example of jig:
FIG. 15 is an explanatory diagram of another embodiment of the jig. FIG. 15A shows a cross section perpendicular to the Y direction of a portion of the jig 100d near the through hole 160d, and FIG. 15B shows a perspective view of a portion of the jig 100d near the through hole 160d. The figure is shown. In this embodiment, unlike the embodiment of FIG. 4A, the side wall portion 120d, not the base wall portion 110d, is provided with an edge portion 150d that forms a through hole 160d used for pulling out the release sheet 300. . The structure of the other part of the jig 100d is the same as the structure of the corresponding part of the jig 100 in FIG. 4A (the same part as the corresponding part is denoted by the same reference numeral and description thereof is omitted). To do).

  The width Wp in the Y direction of the through hole 160d (FIG. 15B) is larger than the width in the Y direction of the release sheet, similarly to the through hole 160 in FIG. Therefore, the user can easily remove the release sheet 300 through the through hole 160d by pulling the tab sheet 330 that has jumped out of the through hole 160d. The procedure for applying the protective sheet 200 is the same as that of the first embodiment except that the position of the through hole 160d is different. As described above, the jig 100d shown in FIG. 15 can suppress foreign matters such as dust from adhering to the adhesive layer 290 of the protective sheet 200, similarly to the jig 100 described above. The through hole 160d extends in the Y direction. Therefore, the width Wp is the width in the longitudinal direction (here, the Y direction) of the through-hole 160d, and is larger than the width Wc in the same direction of the release sheet 300 (FIG. 4A).

  FIG. 16 is an explanatory diagram of another embodiment of the jig. 16A shows a cross section perpendicular to the Y direction of a portion of the jig 100e near the through hole 160e, and FIG. 16B shows a perspective view of a portion of the jig 100e near the through hole 160e. The figure is shown. In the present embodiment, unlike the embodiment of FIG. 4A, the through-hole 160e used for pulling out the release sheet 300 is not the base wall portion 110e but the boundary portion between the base wall portion 110e and the side wall portion 120e. Is formed. That is, the edge part 150e which forms the through-hole 160e is provided in the boundary part of the base wall part 110e and the side wall part 120d. The structure of the other part of the jig 100e is the same as the structure of the corresponding part of the jig 100 in FIG. 4A (the same part as the corresponding part is denoted by the same reference numeral and description thereof is omitted). To do).

  The width Wp in the Y direction of the through hole 160e (FIG. 16B) is larger than the width in the Y direction of the release sheet 300, like the through hole 160 in FIG. Therefore, the user can easily remove the release sheet 300 through the through hole 160e by pulling the tab sheet 330 that has jumped out of the through hole 160e. The procedure for applying the protective sheet 200 is the same as the procedure of the first embodiment except that the position of the through hole 160e is different. As described above, the jig 100e shown in FIG. 16 can suppress foreign matters such as dust from adhering to the adhesive layer 290 of the protective sheet 200, similarly to the jig 100 described above. The through hole 160e extends in the Y direction. Therefore, the width Wp is the width in the longitudinal direction (here, the Y direction) of the through-hole 160e, and is larger than the width Wc in the same direction of the release sheet 300 (FIG. 4A).

  FIG. 16C is an explanatory diagram of an example of a method for forming the through hole 160e. In the drawing, the same cross section as FIG. 16A of the jig 100e before the through hole 160e is formed is shown. As shown in the figure, a connection portion 112e that connects the base wall portion 110e and the side wall portion 120e is provided at a portion corresponding to the through hole 160e. The connecting portion 112e is a wall inclined obliquely with respect to the base wall portion 110e and the side wall portion 120e. The shape of the connecting portion 112e is the same as the shape obtained by chamfering a vertical corner with a plane. A through hole 160e is formed by punching a portion corresponding to the through hole 160e in the connecting portion 112e with the cutter 800. At this time, since the cutter 800 can be moved in a direction perpendicular to the base wall portion 110e, it is easier than moving the cutter 800 in a direction perpendicular to the side wall portion 120e narrower than the base wall portion 110e. The through hole 160e can be formed.

  In addition to the jig 100 of FIG. 4, also in the jigs of other embodiments, the through holes used for pulling out the release sheet may be provided in the side wall part, and the base wall part and You may be provided in the boundary part with a side wall part. Moreover, the through-hole may be provided in several parts among the base wall part, the side wall part, and the boundary part of the base wall part and the side wall part. In any case, the through hole has a width that is greater than the width of the release sheet and is perpendicular to the specific direction from the first peripheral edge of the release sheet to which the tab sheet is connected to the through hole. It is preferable. That is, when the release sheet is viewed from the through hole, the width in the longitudinal direction of the through hole is preferably larger than the width of the release sheet in the same direction as the longitudinal direction of the through hole. According to this configuration, the release sheet can be easily removed from the jig through the through hole. The specific direction indicates a direction in which the tab sheet is assumed to be pulled.

F. Another example of a tab sheet:
FIG. 17A is an explanatory diagram of another example of the tab sheet. Unlike the tab sheet 330 in FIG. 2, the −X side end portion 332 f of the tab sheet 330 f is not folded back, and is fixed to the −Z side surface of the first peripheral edge portion 310 of the release sheet 300. The configuration of the other part of the first composite sheet 600f including the tab sheet 330f is the same as the configuration of the corresponding part of the first composite sheet 600 in FIG. 2 (the same reference numerals are given to the same parts as the corresponding parts). And the explanation is omitted).

  FIG. 17B is an explanatory diagram of still another example of the tab sheet. Unlike the tab sheet 330 of FIG. 2, the release sheet 300 and the tab sheet 330g are formed of a single member. That is, by folding one sheet including the release sheet 300 and the tab sheet 330g at the connection portion 319 of the sheets 300 and 330g, the sheets 300 and 330g in FIG. 17B are formed. The structure of the other part of the first composite sheet 600g including the tab sheet 330g is the same as the structure of the corresponding part of the first composite sheet 600 in FIG. 2 (the same part as the corresponding part is denoted by the same reference numeral). And the explanation is omitted).

  Also when using these 1st composite sheets 600f and 600g, the peeling sheet 300 is removed from the protective sheet 200 similarly to the case where the 1st composite sheet 600 of FIG. 2 is used. Specifically, as described in FIG. 8, when the user pulls the tab sheets 330f and 330g, the first peripheral edge 310 (FIGS. 17A and 17B) of the release sheet 300 is on the −X side. Then, the release sheet 300 gradually moves from the protective sheet 200 to the + X side. The tab sheets 330f and 330g and the release sheet 300 are taken out of the jig through the through holes (for example, the through holes 160 in FIG. 8) of the jig.

  In addition to the first composite sheet 600 of FIG. 2, the composite sheet of another embodiment may use a tab sheet fixed to the surface on the −Z side of the release sheet, or may be composed of one member. You may use the release sheet and tab sheet which were made. Further, such a composite sheet is not limited to the jig 100 of FIG. 8 but can be applied to the case of using a jig of another embodiment. In any case, since the protective sheet after peeling the release sheet is surrounded by the base wall part and the side wall part of the jig, it is possible to prevent foreign matters such as dust from adhering to the adhesive layer of the protective sheet. .

G. Variations:
(1) As a configuration of the jig used for attaching the protective sheet, various other configurations may be adopted instead of the above configuration. For example, the surfaces 122 s, 122 bs, and 122 cs placed on the electronic device 900 or the flat table 1000 (hereinafter also referred to as “mounting target”) may be inclined obliquely with respect to the base wall portions 110, 110 b to 110 e. Further, the surfaces 122s, 122bs, and 122cs may be uneven instead of flat. Further, the above-described flange portions 130 and 130b may be omitted. Also in this case, end portions on the −Z side of the side wall portions 120 and 120b to 120e form end surfaces on the −Z side (for example, end surfaces 122s and 122bs). Such an end surface comes into contact with the surface on the + Z side of the placement object that is about to approach the base wall parts 110, 110b to 110e from the −Z side, and thereby the side wall parts 120, 120b to 120e are placed on the placement object. The space | interval between the base wall parts 110 and 110b-110e can be maintained.

(2) As a configuration of the side wall portion including a positioning portion that determines the relative position of the jig relative to the electronic device 900 and in the direction parallel to the pasting portion when the jig contacts the electronic device 900 in the cover state. Instead of the configuration of the side wall portion 120c in FIGS. 13 and 14, other various configurations can be adopted. For example, the side wall may include a protrusion that protrudes toward the inner peripheral side, and the protrusion may contact the electronic device 900. Such a protrusion may be provided only on a part of the entire circumference of the side wall. Here, the side wall portion may not contact the edge of the electronic device 900 over the entire circumference, but only the protruding portion may contact the edge of the electronic device 900. In any case, in order to determine the relative position, it is preferable that the side wall portion is in contact with the electronic device 900 at a plurality of positions.

  For example, when the external shape of the electronic device 900 is a substantially rectangular parallelepiped as shown in FIG. 13A, the electronic device 900 is viewed in a plan view with respect to the pasted portion (that is, when viewed in a direction perpendicular to the pasted portion). The portions forming the edges are divided into side portions S1 and S3 facing each other, side portions S2 and S4 facing each other, and four corner portions C1 to C4 connecting these side portions S1 to S4. Is possible. It is preferable that a side wall part contacts the some part of these eight parts S1-S4 and C1-C4. As a combination of a plurality of portions in contact with the side wall portion among the eight portions (that is, arrangement of the positioning portion), any combination capable of determining a relative position in a direction parallel to the pasting portion can be adopted. is there. For example, you may employ | adopt four edge parts S1-S4. Moreover, you may employ | adopt four corner | angular parts C1-C4. Moreover, you may employ | adopt two corner | angular parts (for example, corner | angular part C1, C3 or corner | angular part C2, C4) which form a diagonal. Moreover, you may employ | adopt two corner | angular parts located in the both ends of one side part, and one side part which opposes the side part (for example, two corner | angular parts C3 and C4, One side S1). Note that each of the sides S1 to S4 may be curved in a plan view with respect to the pasted portion.

(3) It is preferable that the base wall part of the jig includes a window part formed at a position overlapping the protective sheet in a plan view with respect to the protective sheet when the protective sheet is fixed to the first surface of the base wall part. The window portion is a portion for visually recognizing the positional relationship between the protective sheet and the pasted portion, and includes at least one of an opening and a portion formed of a light-transmitting material. The opening 180 in FIGS. 9 and 12 is an example of an opening included in the window portion. Of the base wall portions 110, 110b, and 110c shown in FIGS. 9A, 12A, and 13D, a portion overlapping the protective sheets 200 and 200c is a light-transmitting material included in the window portion. It is an example of the part formed by.

  As the window portion, only one of the opening and the portion formed of a light-transmitting material may be provided on the base wall portion. For example, in the embodiment of FIGS. 9 and 12, since the entire base wall portions 110 and 110b are made of a light-transmitting material, the opening 180 may be omitted.

  The base wall portion may be formed using an opaque material (for example, a metal or a light shielding resin). Also in this case, when the base wall portion includes the window portion, the user can easily adjust the position of the protective sheet with respect to the pasted portion.

  In addition, it is preferable that at least one part of the whole of a base wall part and a side wall part is formed with the flexible material. According to this structure, even if it is a case where opening is abbreviate | omitted from a base wall part, a protective sheet can be affixed on a sticking part by deform | transforming the part formed with the flexible material. In addition, as a flexible material, you may employ | adopt at least one of a metal and resin, for example. As the metal, for example, aluminum, copper, iron or the like may be employed. For example, polystyrene, PET, polyethylene, polypropylene, or the like may be employed as the resin. In the case where the base wall portion has an opening, a portion formed of a flexible material may be omitted from the entire base wall portion and the side wall portion (for example, between the base wall portion and the side wall portion). The whole may be formed of a hard material (eg ceramic)).

(4) As the shape of the jig, other various shapes may be adopted instead of the above shape. For example, at least a part of the side wall portions 120, 120b to 120e is perpendicular to the first surfaces 111, 111b, and 111c of the base wall portions 110, 110b to 110e (in the above embodiments, the −Z direction). It may be inclined obliquely. Further, the shape of the plate-like base wall portions 110, 110b to 110e in a plan view may be other various shapes such as a circle and an ellipse instead of a substantially rectangular shape.

  Further, as in the embodiments of FIGS. 12 and 13, notches (for example, notches 128 and 128c) may be provided in a part of the side wall portion. In this specification, also in this case, the sum of the lengths of the portions where the side wall portions are provided in the entire circumference of the peripheral edge portion of the base wall portion is the peripheral length of the base wall portion (that is, the total length of the peripheral edge portion). If it exceeds half, the side wall portion surrounds the first surface of the base wall portion.

(5) As the respective configurations of the protective sheet and the composite sheet including the protective sheet, other various configurations may be adopted instead of the above configuration. For example, the cover sheets 400 and 400c may be omitted. In particular, when a hard material (for example, glass) is used as the material of the base material layer 210 of the protective sheets 200 and 200c, the base material layer 210 is hardly damaged. Therefore, even if the cover sheets 400 and 400c are omitted, the base material layer 210 is prevented from being damaged. Here, when the mark 430 is used for alignment, the mark 430 may be directly attached to the base material layer 210 of the protective sheet 200.

  Moreover, the structure of a tab sheet | seat can employ | adopt other various structures instead of said structure. For example, the width of the tab sheet may be the same as the width of the release sheet. The material of the tab sheet may be different from the material of the release sheet. The tab sheet and the release sheet may be formed using an opaque material.

  Further, as a configuration for positioning provided in the composite sheet, various other configurations can be employed instead of the mark 430 (FIG. 9 and the like) and the through holes 602 and 604 (FIG. 13). Generally, at least one of a specific shape part (for example, a through-hole or a corner) indicating the position of a specific part of the electronic device 900 and a mark can be employed (hereinafter referred to as “position display unit”). Call). For example, a mark (for example, an arrow) indicating the corner position of the display surface 990 may be employed. In addition, a layer representing the mark (for example, the mark 430) may be omitted, and an image representing the mark may be printed on the cover sheet 400 (for example, the base material layer 410). Further, the corner of the protective sheet 200 may be matched with the corner of the display surface 990. In any case, the position display unit may be provided on the protective sheet, or may be provided on another sheet (for example, the cover sheet 400) different from the protective sheet. In general, the position display unit is preferably provided on at least one sheet of a composite sheet including a protective sheet. Moreover, it is preferable that at least a part of the position display portion overlaps the window portion in a state where the protective sheet is fixed to the base wall portion of the jig.

  In any case, the shortest distance (for example, the shortest distance T3 in FIGS. 7A and 12B) between the first surface of the base wall portion and the attachment portion of the electronic device is at least the thickness of the protective sheet. It is preferable to be larger than the thickness (for example, the thickness T1 in FIGS. 7A and 12B). According to this structure, it can suppress that foreign materials, such as dust, adhere to the sticking surface of a protection sheet in a cover state. Moreover, it can suppress that a protection sheet contacts the sticking part of an electronic device unintentionally.

(6) As the shape of the part to which the tab sheet of the release sheet is connected, other arbitrary shapes can be adopted instead of the shapes of the first peripheral edge portions 310, 310a, 310b shown in FIGS. is there. In any case, it is preferable that the tab sheet 330 is connected to the peripheral edge of the release sheet that protrudes from the edge of the protective sheet. According to this configuration, by pulling the tab sheet, the release sheet can be folded back from the peripheral edge protruding from the edge of the protective sheet as shown in FIGS. 8 (A) and 8 (B). The release sheet can be peeled off. However, the tab sheet may be connected to a peripheral edge portion that overlaps the protective sheet of the release sheet. Also in this case, when the folded portion (for example, the folded portion 308 in FIG. 8C) moves from the peripheral edge of the release sheet, the release sheet is removed from the protective sheet as shown in FIGS. 8B to 8D. Can be peeled off. In this case, the release sheet may be composed of only a portion that does not protrude from the edge of the protective sheet and overlaps the protective sheet in a state of being attached to the protective sheet.

(7) As a configuration of the fixing portion for fixing the composite sheet including the protective sheet and the release sheet to the base wall portion of the jig, the fixing portion 700 in FIG. 3 and the protruding portions 118 and 119 in FIG. Instead, various other configurations may be employed. For example, a double-sided tape in which the base material layer 710 is omitted from the fixing portion 700 of FIG. 3 and the second adhesive layer 730 is directly attached to the + Z side surface of the first adhesive layer 720 may be employed. Moreover, the base material layer 710 and the 2nd adhesion layer 730 may be abbreviate | omitted from the fixing | fixed part 700 of FIG. 3, and the double-sided tape comprised only by the 1st adhesion layer 720 may be employ | adopted. Moreover, it may replace with the double-sided tape containing the layer of an adhesive, and may employ | adopt the adhesives of other arbitrary shapes different from a tape-shaped shape. Moreover, you may use the notch | incision formed in the base wall part as a fixing | fixed part. The composite sheet can be fixed to the base wall portion by inserting a part of the composite sheet (for example, the edge portion of the cover sheet) into the cut. In any case, the fixing unit may directly fix the protective sheet, or indirectly fix the protective sheet via another member (for example, the cover sheet 400) connected to the protective sheet. May be.

(8) The pasting portion of the electronic device may include a curved surface. For example, when at least a part of the display surface 990 (FIG. 6) (for example, the + Y side edge part and the −Y side edge part) is curved, the pasting part may include the curved part. In such a case, as the protective sheet, a protective sheet including a portion curved in advance according to the pasted portion may be used. Moreover, you may stick a flat protective sheet to the curved sticking part by curving a protective sheet. In this case, you may stick the whole protection sheet to a sticking part by making a part of protection sheet contact a sticking part, and then expanding a contact part.

  Further, a part of the display surface 990 may be detached from the pasted portion. That is, the pasting portion may be a region including at least a part of the display surface 990. Instead of this, the pasted portion may be a region (for example, a part of the surface opposite to the front surface 910) that is distant from the display surface 990 on the surface of the electronic device.

(9) As a combination of the configuration of the jig and the configuration of the composite sheet, a combination arbitrarily selected from the configuration of the plurality of jigs described above and the configuration of the plurality of composite sheets described above may be employed. For example, the first composite sheet 600c of FIG. 13 may be combined with the jig 100 of FIG. 4 or the jig 100b of FIG. In this case, the first composite sheet 600c is fixed to the base wall portions 110 and 110b by the fixing portion 700. The user adjusts the position of the jig 100 with respect to the electronic device 900 so that the through holes 602 and 604 of the first composite sheet 600c overlap the buttons 992 and the holes 994 of the electronic device 900, thereby protecting the protective sheet for the pasted portion 900tc. 200 positions can be adjusted. Here, the display of the mark 980 (FIG. 6) by the electronic device 900 is omitted. Furthermore, the openings 180 of the jigs 100 and 100b may be omitted.

  Moreover, you may comprise a package using the system provided with the composite sheet | seat provided with a protective sheet and the peeling sheet provided in the sticking surface of the protective sheet, and a jig | tool. If it carries out like this, a protection sheet can be stuck to an electronic device using the jig | tool contained in a package. Note that a cover sheet may be attached to the protective sheet, or the cover sheet may be omitted. Moreover, it is preferable that the composite sheet including the protective sheet and the release sheet is disposed in a region surrounded by the base wall portion and the side wall portion of the jig. If it carries out like this, a deformation | transformation of a protection sheet can be suppressed. Here, the protective sheet is preferably fixed to the base wall portion in advance. However, the protective sheet may be removed from the base wall. In any case, when a fixing part including an adhesive is used, the fixing part is also preferably included in the package. Moreover, the sheet | seat which closes the opening formed by a side wall part may be affixed on the side wall part of a jig | tool. The package may include a bag that accommodates the jig and the composite sheet. Note that the jig and the composite sheet may be provided independently.

(10) As the shape of the electronic device to which the protective sheet is attached, any other shape may be employed instead of the substantially rectangular parallelepiped. For example, the shape of the electronic device may be a disk shape. Moreover, as an electronic device, it may replace with a smart phone and a tablet computer, and may employ | adopt other various types of electronic devices. For example, a watch-type computer (also called a smart watch) may be employed.

(11) As a method of attaching the protective sheet using a jig, another method different from the above method may be adopted. For example, after removing the release sheet through the through hole of the jig, the jig may be placed on the electronic device. Also in this case, since the protective sheet with the release sheet removed is surrounded by the base wall part and the side wall part, it is possible to prevent foreign matters such as dust from adhering to the application surface of the protective sheet.
