Modes for Carrying Out the Invention

[0014] (Embodiment) Hereinafter, the electronic device 1 according to the embodiment will be described with reference to the drawings. The configurations of the embodiments described below, as well as the actions and results (effects) brought about by these configurations, are merely examples and are not limited to the following description.

[0015] In addition, a plurality of embodiments disclosed below include similar components. Therefore, hereinafter, the same reference numerals will be given to these similar components, and duplicate descriptions will be omitted. In this specification, ordinal numbers are used only for distinguishing parts and members and do not indicate order or priority.

[0016] <First Embodiment> FIG. 1 is a perspective view of the electronic device 1 according to the first embodiment. The electronic device 1 of this embodiment is a laptop PC. However, the electronic device 1 is not limited to this, and may be, for example, a tablet PC, a smartphone, an electronic dictionary, or a game machine.

[0017] As shown in FIG. 1, the electronic device 1 includes a base housing 2, a hinge 3, a display device 4, and a display unit housing 5. Note that the base housing 2 is an example of a second housing, and the hinge 3 is an example of a connecting portion. Further, the display unit housing 5 is an example of a first housing.

[0018] In the following figures, for convenience, three mutually orthogonal directions are defined. The X direction is a direction along the short side direction of the base housing 2 and can also be referred to as the front-rear direction. The Y direction is a direction along the long side direction of the base housing 2 and can also be referred to as the left-right direction. The Z direction is a direction along the thickness direction of the base housing 2 and can also be referred to as the up-down direction. Note that the expressions indicating directions such as front, rear, left, right, up, and down in this embodiment are for convenience of naming and do not limit the position, posture, and usage mode of the electronic device 1.

[0019] Furthermore, in FIG. 1, for convenience, the short side direction of the display device 4 is defined as Dw. The short side direction Dw changes depending on the inclination (opening angle) of the display device 4 with respect to the base housing 2. In the example of FIG. 1, the short side direction Dw is along the Z direction. The upward direction in FIG. 1 in the short side direction Dw is an example of a first direction, and the downward direction in FIG. 1 in the short side direction Dw is an example of a second direction.

[0020] The base housing 2 has an upper surface 21. The upper surface 21 is a substantially flat surface facing in a substantially upward direction (+Z direction). The upper surface 21 extends along a direction (XY plane) orthogonal to the up-down direction (Z direction). Note that the upper surface 21 is not limited to this example and may have irregularities.

[0021] The base housing 2 houses, for example, a substrate, a CPU, a ROM, a RAM, a storage such as an HDD or an SSD, a battery, an antenna, and various other components. A plurality of keys 22 and a touch pad 23, which are input means, are provided on the upper surface 21 of the base housing 2.

[0022] The hinge 3 connects the base housing 2 and the display unit housing 5 so that they can rotate relative to each other. The hinge 3 is provided at the rear end 2a which is the end of the base housing 2 in the rearward (-X direction). The hinge 3 connects the rear end 2a of the base housing 2 and the lower end 5a which is the end of the display unit housing 5 in the downward direction in the short side direction Dw. Note that the lower end 5a is an example of an end.

[0023] The display device 4 is a device capable of displaying an image such as, for example, a liquid crystal display (LCD) or an organic EL display. The display device 4 has a display surface 41. The display surface 41 is formed substantially flat and can display an image. A touch panel may be provided on the display surface 41, for example. In that case, the user can operate the display device 4 by a touch operation on the display surface 41.

[0024] FIG. 2 is a plan view of the display unit housing 5 of the first embodiment. As shown in FIG. 2, the display device 4 has an upper edge 42 and a lower edge 43. Note that the upper edge 42 is an example of a first edge, and the lower edge 43 is an example of a second edge.

[0025] The upper edge 42 is an edge facing upward in the short side direction Dw of the display device 4. The short side direction Dw is a direction along the display surface 41. In the present embodiment, the upper edge 42 is provided at the upper end of the display device 4 in the upward direction in the short side direction Dw. Note that the upper edge 42 is not limited to this example.

[0026] The lower edge 43 is an edge facing downward in the short side direction Dw of the display device 4. The lower edge 43 is located on the opposite side of the upper edge 42. In the present embodiment, the lower edge 43 is provided at the lower end of the panel of the display device 4 in the downward direction in the short side direction Dw. For example, the substrate of the display device 4 protrudes downward in the short side direction Dw from a substantially central portion of the panel of the display device 4 in the width direction (Y direction). Note that the lower edge 43 is not limited to this example.

[0027] The display unit housing 5 is rotatably attached to the hinge 3. In the present embodiment, the display unit housing 5 attached to the hinge 3 can rotate with respect to the base housing 2 and the hinge 3. The display unit housing 5 is made of, for example, metal or resin, and is formed in a substantially rectangular (quadrangular) thin box shape. Various components such as the display device 4 are housed in the space inside the display unit housing 5.

[0028] As shown in FIG. 1, the display unit housing 5 has a back cover 51 and a bezel 52. The back cover 51 and the bezel 52 are combined in the thickness direction of the display unit housing 5 and can be separated from each other, for example, during disassembly.

[0029] As shown in FIG. 2, the back cover 51 has a rear wall 53 and a peripheral wall 54. The rear wall 53 covers the back surface of the display device 4 that is located on the opposite side of the display surface 41. The rear wall 53 has an inner surface 55 and a positioning wall 56. Note that the positioning wall 56 is an example of a wall.

[0030] The inner surface 55 is a substantially flat surface facing the inside of the display unit housing 5. Note that the inner surface 55 may be provided with irregularities or a curved surface. The inner surface 55 faces the back surface of the display device 4.

[0031] The positioning wall 56 protrudes in the thickness direction of the display unit housing 5 from the inner surface 55 at a position adjacent to the upper edge 42 of the display device 4. The upper edge 42 of the display device 44 faces the positioning wall 56. The positioning wall 56 may be in contact with the upper edge 42 or may be slightly separated from the upper edge 42.

[0032] The peripheral wall 54 is a frame-shaped wall protruding from the edge of the rear wall 53 and surrounds the display device 4. The positioning wall 56 is located inside the peripheral wall 54. Note that the positioning wall 56 may be omitted, and a part of the peripheral wall 54 may be adjacent to the upper edge 42 of the display device 44.

[0033] The bezel 52 is attached to the peripheral wall 54 of the back cover 51. As shown in FIG. 1, the bezel 52 has a front surface 57. The front surface 57 is a substantially flat surface that faces approximately forward (+X direction) when the electronic device 1 is in the open state as shown in FIG. 1. The front surface 57 extends along a direction (YZ plane) orthogonal to the direction (+X direction) in which the front surface 57 faces.

[0034] An opening 58 is provided in the bezel 52. The opening 58 opens to the front surface 57. The opening 58 exposes the display surface 41 to the outside of the display unit housing 5. That is, the display surface 41 faces forward (+X direction) of the display unit housing 5 through the opening 58. The bezel 52 surrounds the display surface 41 of the display device 4.

[0035] FIG. 3 is an enlarged plan view of a part of the display unit housing 5 in FIG. 2. As shown in FIG. 3, the display unit housing 5 has a protrusion 59. The protrusion 59 protrudes in the thickness direction of the display unit housing 5 from the inner surface 55 at a position adjacent to the lower edge 43 of the display device 4. The protrusion 59 is spaced apart from the lower edge 43.

[0036] As shown in FIG. 2, the electronic device 1 further includes a stretch release tape 7. The stretch release tape 7 adheres the display device 4 to the display unit housing 5. That is, the stretch release tape 7 is housed in the display unit housing 5. In this embodiment, two stretch release tapes 7 are provided. However, the number of stretch release tapes 7 is not limited to two and may be changed as appropriate.

[0037] Each stretch release tape 7 is attached to the inner surface 55 while being spaced apart from each other in the width direction (Y direction) of the display unit housing 5. Note that the direction in which each stretch release tape 7 is spaced apart from each other is not limited to the width direction of the display unit housing 5. For example, each stretch release tape 7 may be attached to the inner surface 55 while being spaced apart from each other in the short side direction Dw of the display device 4.

[0038] Each stretch release tape 7 is attached to the inner surface 55 of the display unit housing 5 and extends along the short side direction Dw of the display device 4. The two stretch release tapes 7 are attached to both ends of the display device 4 in the Y direction on the back surface of the display device 4 to the inner surface 55.

[0039] The end 7a of the stretch release tape 7 in the upward direction in the short side direction Dw of the display device 4 is located between the upper edge 42 and the lower edge 43 of the display device 4 in the short side direction Dw of the display device 4 and is closer to the upper edge 42 than the lower edge 43. In other words, in the short side direction Dw of the display device 4, the distance between the end 7a of the stretch release tape 7 and the upper edge 42 is shorter than the distance between the end 7a and the lower edge 43.

[0040] The end 7a of the stretch release tape 7 is separated from the positioning wall 56. Also, the end 7a of the stretch release tape 7 is separated from the upper edge 42 of the display device 4. Note that the stretch release tape 7 may extend up to the upper edge 42 or may extend across the upper edge 42.

[0041] The stretch release tape 7 has an intervening portion 71. The intervening portion 71 is a portion that is located between the display device 4 and the inner surface 55 of the display unit housing 5 and adheres the display device 4 to the inner surface 55 of the display unit housing 5 when the display device 4 is housed in the display unit housing 5. That is, the intervening portion 71 adheres the inner surface 55 of the display unit housing 5 facing the display device 4 to the display device 4.

[0042] The intervening portion 71 has a first adhesive surface 711. Note that the first adhesive surface 711 is an example of the first surface. The first adhesive surface 711 is one surface of the intervening portion 71 and faces the display device 4 in the intervening portion 71 when the display device 4 is housed in the display unit housing 5. Note that the first adhesive surface 711 is not limited to this, and for example, it may face the inner surface 55 of the display unit housing 5 when the display device 4 is housed in the display unit housing 5.

[0043] The first bonding surface 711 has a first bonding area 711a and a non-bonding area 711b. Note that the first bonding area 711a is an example of the first part, and the non-bonding area 711b is an example of the second part.

[0044] The first bonding area 711a is a part that bonds to the display device 4 or the display unit housing 5 when the display device 4 is housed in the display unit housing 5. That is, the first bonding area 711a has adhesiveness.

[0045] The first bonding area 711a includes the end 7a of the stretch release tape 7 and is provided above the non-bonding area 711b in the short-side direction Dw of the display device 4. Note that the range of the first bonding area 711a may be changed as appropriate.

[0046] The non-bonding area 711b is a non-bonding part on the first bonding surface 711. The non-bonding area 711b is formed, for example, by attaching a non-bonding layer to the first bonding surface 711. Note that the method of forming the non-bonding area 711b is not limited to this. For example, the non-bonding area 711b may be formed by applying a varnish or the like to a part of the first bonding surface 711.

[0047] The non-bonding area 711b is provided between the lower edge 43 of the display device 4 and the first bonding area 711a. Therefore, the non-bonding area 711b is closer to the hinge 3 than the first bonding area 711a. The non-bonding area 711b of the present embodiment is closer to the lower edge 43 than the upper edge 42. Note that the range of the non-bonding area 711b may be changed as appropriate.

[0048] As shown in FIG. 3, the stretch release tape 7 further has a knob portion 72. The knob portion 72 is also referred to as a peeling margin. The knob portion 72 extends from the end 71a of the intervening portion 71 in the downward direction in the short-side direction Dw of the display device 4 across the lower edge 43 of the display device 4 to the outside of the space between the display device 4 and the display unit housing 5 when the display device 4 is housed in the display unit housing 5. That is, the non-bonding area 711b is located between the first bonding area 711a and the knob portion 72.

[0049] One surface of the continuous grip portion 72 from the non - adhesive area 711b is, for example, non - adhesive. The other surface of the grip portion 72 has adhesiveness and is attached to the protrusion 59. Note that both surfaces of the grip portion 72 may have adhesiveness. A part of the grip portion 72 is in contact with the protrusion 59 of the display unit housing 5 and is separated from the inner surface 55 of the display unit housing 5.

[0050] When disassembling and repairing the electronic device 1, the display device 4 may be removed from the display unit housing 5. In this case, the operator disassembles the display unit housing 5 to expose the display device 4 housed in the display unit housing 5 to the outside. The operator pinches and pulls the grip portion 72 of the stretch release tape 7 that extends across the lower edge 43 of the display device 4.

[0051] When the stretch release tape 7 is pulled, its adhesive force is reduced. For this reason, when the grip portion 72 of the stretch release tape 7 is pulled by the operator, the adhesive force is reduced and the stretch release tape 7 peels off from the back surface of the display device 4 and the inner surface 55 of the display unit housing 5. As a result, the display device 4 is removed from the display unit housing 5.

[0052] As described above, the stretch release tape 7 that can easily remove the display device 4 from the display unit housing 5 adheres the display device 4 to the display unit housing 5. On the other hand, in a conventional electronic device, for example, a display device may be adhered to a display unit housing by four stretch release tapes.

[0053] In the above - mentioned conventional electronic device, the grip portions of two stretch release tapes extend across the lower edge of the display device, and the grip portions of the other two stretch release tapes extend across the upper edge of the display device. For this reason, in the above - mentioned conventional electronic device, spaces for accommodating the grip portions of the stretch release tapes are provided near the upper edge and the lower edge of the display device. For this reason, the width of the bezel near the upper edge of the display device may become thick.

[0054] On the one hand, in the electronic device 1 of the present embodiment, the stretch release tape 7 does not extend across the upper edge 42 of the display device 4. That is, the display unit housing 5 is provided with a space for accommodating the grip portion 72 of the stretch release tape 7 near the lower edge 43 of the display device 4, but not near the upper edge 42. Therefore, the display unit housing 5 can reduce the space near the upper edge 42 of the display device 4. Accordingly, the width of the bezel 52 near the upper edge 42 of the display device 4 can be narrowed. Thus, the electronic device 1 can be miniaturized.

[0055] Also, the end 7a of the stretch release tape 7 is located between the upper edge 42 and the lower edge 43 of the display device 4 in the short-side direction Dw of the display device 4, and is arranged at a position closer to the upper edge 42 than the lower edge 43. In the present embodiment, the intervening portion 71 of the stretch release tape 7 adheres the display device 4 and the display unit housing 5 across between the vicinity of the upper edge 42 and the lower edge 43. Therefore, the stretch release tape 7 can adhere a sufficient area of the display device 4 to the inner surface 55 of the display unit housing 5. As a result, for example, in the electronic device 1, another stretch release tape having a grip portion extending across the upper edge 42 of the display device 4 becomes unnecessary.

[0056] Also, when the electronic device 1 is opened and closed, the user grips the end portion of the display unit housing 5 in the upward direction in the short-side direction Dw of the display device 4 and rotates the display unit housing 5 around the hinge 3. At this time, at the hinge 3, a resistance to the rotation of the display unit housing 5 occurs. Due to the external force applied by the user to the end portion of the display unit housing 5 and the resistance at the hinge 3, the display unit housing 5 may bend near the hinge 3.

[0057] When the display unit housing 5 is curved, due to the difference in rigidity between the display device 4 and the display unit housing 5, relative displacement occurs between the display device 4 and the display unit housing 5. In the vicinity of the lower edge 43 of the display device 4 located near the hinge 3, the relative displacement between the display device 4 and the display unit housing 5 becomes large. If the entire area of the first adhesive surface 711 of the stretch release tape 7 has adhesiveness, there is a risk that the display device 4 will be peeled off from the stretch release tape 7 in the vicinity of the lower edge 43 due to the relative displacement between the display device 4 and the display unit housing 5.

[0058] However, in the electronic device 1 of the present embodiment, the non-adhesive area 711b of the stretch release tape 7 is located between the first adhesive area 711a and the grip portion 72. In other words, the non-adhesive area 711b is provided in the vicinity of the lower edge 43. Therefore, in the vicinity of the lower edge 43 of the display device 4, the display device 4 does not adhere to the stretch release tape 7. As a result, peeling of the display device 4 from the stretch release tape 7 due to the relative displacement between the display device 4 and the display unit housing 5 at the lower edge 43 of the display device 4 is suppressed. Furthermore, abnormal noise generated by peeling of the display device 4 from the stretch release tape 7 is suppressed.

[0059] As described above, the electronic device 1 of the present embodiment includes a display device 4, a display unit housing 5, and a stretch release tape 7. The display device 4 has a display surface 41 capable of displaying an image, an upper edge 42 facing upward in the short-side direction Dw of the display device 4 along the display surface 41, and a lower edge 43 located on the opposite side of the upper edge 42. The display unit housing 5 houses the display device 4. The stretch release tape 7 adheres the display device 4 to the display unit housing 5. Further, the stretch release tape 7 has an intervening portion 71 and a gripping portion 72. The intervening portion 71 is located between the display device 4 and the display unit housing 5 and adheres the display device 4 to the display unit housing 5. The gripping portion 72 extends across the lower edge 43 from the end 71a of the intervening portion 71 in the downward direction of the short-side direction Dw of the display device 4 and is located outside the space between the display device 4 and the display unit housing 5. The intervening portion 71 has a first adhesive surface 711 facing one of the components of the display device 4 and the display unit housing 5. The first adhesive surface 711 has a first adhesive area 711a adhered to the display device 4 or the display unit housing 5, and a non-adhesive area 711b located between the first adhesive area 711a and the gripping portion 72 and being non-adhesive. The end 7a of the stretch release tape 7 is located between the upper edge 42 and the lower edge 43 in the direction along the display surface 41 and is closer to the upper edge 42 than the lower edge 43.

[0060] When disassembling and repairing the electronic device 1, the operator removes the display device 4 from the display unit housing 5 by peeling off the stretch release tape 7 that adheres the display device 4 and the display unit housing 5. When peeling the stretch release tape 7 from the display device 4 and the display unit housing 5, the operator grips and pulls the gripping portion 72 of the stretch release tape 7 to reduce or eliminate the adhesive force of the stretch release tape 7.

[0061] In the electronic device 1 of the present embodiment, the grip portion 72 extends across the lower edge 43 of the display device 4. Further, by arranging the end 7a of the stretch release tape 7 at a position closer to the upper edge 42 than the lower edge 43, the stretch release tape 7 can adhere a sufficient area of the display device 4 to the display unit housing 5, and another stretch release tape having a grip portion extending across the upper edge 42 becomes unnecessary. Therefore, if the display unit housing 5 is provided with a space for accommodating the grip portion 72 in the vicinity of the lower edge 43, the space in the vicinity of the upper edge 42 can be reduced. As a result, the width of the bezel 52 of the display unit housing 5 in the vicinity of the upper edge 42 can be narrowed, and the electronic device 1 can be miniaturized.

[0062] Also, for example, when the display unit housing 5 is curved by an external force, a relative displacement between the display device 4 and the display unit housing 5 occurs due to the difference in rigidity between the display device 4 and the display unit housing 5. In the vicinity of the lower edge 43, the relative displacement between the display device 4 and the display unit housing 5 may increase. However, in the electronic device 1 of the present embodiment, the non-adhesive non-adhesive area 711b is located between the adhesive first adhesive area 711a and the grip portion 72. That is, in the vicinity of the lower edge 43, the stretch release tape 7 is not adhered to the component. Therefore, peeling of the stretch release tape 7 in the vicinity of the lower edge 43 due to the relative displacement between the display device 4 and the display unit housing 5, and generation of abnormal noise due to the peeling are suppressed.

[0063] Further, in the present embodiment, the electronic device 1 further includes a base housing 2 and a hinge 3. The hinge 3 connects the base housing 2 and the lower end portion 5a of the display unit housing 5 so that the base housing 2 and the display unit housing 5 can rotate relative to each other.

[0064] When the base housing 2 is rotated with respect to the display unit housing 5, for example, the user grips an end of the display unit housing 5 in the upward direction of the short side direction Dw of the display device 4 and applies torque to the display unit housing 5. At this time, resistance to the torque occurs in the hinge 3, and the display unit housing 5 may bend significantly in the vicinity of the hinge 3. The lower edge 43 is located in the vicinity of the hinge 3. For this reason, when the display unit housing 5 bends, the relative displacement between the display device 4 and the display unit housing 5 may increase in the vicinity of the lower edge 43. However, in the electronic device 1 of the present embodiment, since the first adhesive surface 711 has a non-adhesive non-adhesive area 711b, generation of abnormal noise due to peeling of the stretch release tape 7 is suppressed.

[0065] Further, in the present embodiment, the display unit housing 5 has an inner surface 55 and a protrusion 59. The inner surface 55 faces the display device 4 and is adhered to the display device 4 by the intervening portion 71. The protrusion 59 protrudes from the inner surface 55 and contacts the knob portion 72. By contacting the knob portion 72, the protrusion 59 separates the knob portion 72 from the inner surface 55. Thereby, it becomes easier for the operator to grip the knob portion 72 of the stretch release tape 7.

[0066] Further, in the present embodiment, the display unit housing 5 has a positioning wall 56. The upper edge 42 faces the positioning wall 56. The end 7a of the stretch release tape 7 is separated from the upper edge 42. When the display device 4 is attached to the display unit housing 5, the operator can set the position of the display device 4 in the upward direction of the short side direction Dw of the display device 4 to a desired position by bringing the upper edge 42 into contact with the positioning wall 56. At this time, the operator can prevent the display device 4 from adhering to the stretch release tape 7 before positioning the display device 4 by tilting the display device 4 obliquely with respect to the display unit housing 5 so that a portion of the display device 4 excluding the upper edge 42 is separated from the display unit housing 5.

[0067] <Second Embodiment> FIG. 4 is an enlarged plan view of a part of the display unit housing 5 and the stretch release tape 7A of the second embodiment. As shown in FIG. 4, the stretch release tape 7A of the second embodiment has the same configuration as the stretch release tape 7A of the first embodiment, except for the configuration described below. Therefore, also according to the second embodiment, the effects based on the same configuration as the first embodiment can be obtained.

[0068] In the stretch release tape 7A of the second embodiment, the grip portion 72A has a second adhesive surface 721 continuous with the first adhesive surface 711. In other words, among one surface of the stretch release tape 7A, the portion included in the intervening portion 71 is the first adhesive surface 711, and the portion included in the grip portion 72A is the second adhesive surface 721. Note that the second adhesive surface 721 is an example of a second surface.

[0069] The second adhesive surface 721 has a second adhesive area 721a having adhesiveness. Note that the second adhesive area 721a is an example of a third portion. In the stretch release tape 7A, the second adhesive area 721a is located below the non - adhesive area 711b in the short - hand direction Dw of the display device 4.

[0070] The second adhesive area 721a may be provided over the entire area of the second adhesive surface 721, or may be provided on a part of the second adhesive surface 721. That is, a non - adhesive portion may be provided on the second adhesive surface 721.

[0071] FIG. 5 is a cross - sectional view of the display unit housing 5 and the stretch release tape 7A of the second embodiment. FIG. 5 shows a state where an operator attaches the stretch release tape 7A to the display unit housing 5.

[0072] As shown in FIG. 5, generally, a separator S is attached to a first adhesive surface 711 and a second adhesive surface 721 of an unused stretch release tape 7A. When assembling the electronic device 1, an operator attaches the stretch release tape 7A to the inner surface 55 of the display unit housing 5. At this time, in order to attach the stretch release tape 7A straight to the inner surface 55, the operator pulls the stretch release tape 7A downward in the short-side direction Dw as shown by the arrow in FIG. 5 while attaching it to the inner surface 55.

[0073] The separator S is less likely to stretch than the stretch release tape 7A. For this reason, for example, when the second adhesive area 721a is not provided on the stretch release tape 7A, when the operator pulls the stretch release tape 7A, the separator S does not stretch, but the stretch release tape 7A stretches. Therefore, there is a possibility that the stretch release tape 7A may not fit within the display unit housing 5.

[0074] However, in the stretch release tape 7A of the present embodiment, the second adhesive area 721a is provided in the grip portion 72A. Thereby, when the operator pulls the stretch release tape 7A, since the separator S is adhered to the second adhesive area 721a, it is possible to suppress the stretch release tape 7A from stretching.

[0075] As described above, in the stretch release tape 7A of the present embodiment, the grip portion 72A has a second adhesive surface 721 continuous with the first adhesive surface 711. The second adhesive surface 721 further has a second adhesive area 721a having adhesiveness.

[0076] The unused stretch release tape 7A generally has a separator S attached thereto. The separator S extends across, for example, the non-adhesive non-adhesive area 711b and adheres to the adhesive first adhesive area 711a and the second adhesive area 721a. When attaching the stretch release tape 7A to the display unit housing 5, the operator attaches the stretch release tape 7A to the display unit housing 5 while pulling it. Since the separator S extends across the non-adhesive area 711b and adheres to the first adhesive area 711a and the second adhesive area 721a, when the operator pulls the stretch release tape 7A, the separator S can suppress the stretch release tape 7A from stretching between the first adhesive area 711a and the non-adhesive area 711b. Thereby, it is suppressed that the grip portion 72A extending across the lower edge 43 becomes longer due to the stretching of the stretch release tape 7A.

[0077] As described above, the embodiments of the present invention have been explained. However, the above embodiments are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the gist of the invention. Also, each configuration, shape, etc. of the specifications (structure, type, direction, form, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.
