Description

Technical Field

[0001] The present invention relates to a belt member and an electronic device by means of the belt member for fixing a display panel. Background Technology

[0002] Electronic devices such as laptop PCs have display panels, such as LCD screens. Preferably, the display panel can be removed for maintenance. Therefore, Patent Document 1 discloses a structure that uses a stretchable, peelable double-sided adhesive tape to fix the display panel.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2022-079985

[0004] For structures where the display panel is secured with double-sided adhesive tape, as described above, a handle for gripping during peeling or pulling needs to extend to the side of the display panel. However, depending on the housing structure, it is sometimes impossible to place a handle near the fixing position of the display panel formed by double-sided adhesive tape.

[0005] In such cases, a sheet material serving as a handle component is sometimes attached to the end of the double-sided adhesive tape, extending the sheet to the side of the display panel. However, for structures where a handle component is attached to the double-sided adhesive tape, it is known that, for example, when the stretching distance of the double-sided adhesive tape is long, the handle component may sometimes detach from the double-sided adhesive tape. If the handle component detaches from the double-sided adhesive tape during peeling, double-sided adhesive tape will remain on the back of the display panel, making it difficult to remove the display panel. Summary of the Invention

[0006] The present invention was made in view of the problems of the prior art described above, and its object is to provide a tape member capable of preventing the handle member from detaching from the double-sided adhesive tape, and an electronic device by means of the tape member for fixing the display panel.

[0007] The first aspect of the present invention includes a tape member comprising: a double-sided adhesive tape having the characteristic of being stretchable and peelable by stretching its end; and a handle member mounted on the end of the double-sided adhesive tape and held during stretching and peeling of the double-sided adhesive tape. The handle member comprises: a first adhesive sheet fixed to a first adhesive surface of the double-sided adhesive tape; and a second adhesive sheet fixed to a second adhesive surface of the double-sided adhesive tape. A stop edge extending in a direction intersecting the stretching direction during stretching and peeling is provided at the end of the double-sided adhesive tape. The handle member has a hook portion formed by the first adhesive sheet and the second adhesive sheet being bonded together with each other on the rear side of the stop edge in relation to the stretching direction, and hooking onto the stop edge during stretching and peeling.

[0008] The electronic device according to the first aspect of the present invention includes: a housing member having an inner surface; a display panel having a display surface, and an inner surface opposite to the display surface being supported by the inner surface of the housing member; and a strap member having double-sided adhesive tape and a handle member, wherein the double-sided adhesive tape has the characteristic of being stretchable and peelable by stretching its end, the handle member is mounted to the end of the double-sided adhesive tape and is gripped when stretching and peeling the double-sided adhesive tape, and the strap member fixes the inner surface of the display panel to the housing member. On the inner surface, the handle member has: a first adhesive sheet fixed to the first adhesive surface of the double-sided adhesive tape; and a second adhesive sheet fixed to the second adhesive surface of the double-sided adhesive tape. A stop edge portion extending in a direction intersecting the stretching direction during stretching and peeling is provided at the end of the double-sided adhesive tape. The handle member has a hook portion formed by the first adhesive sheet and the second adhesive sheet being adhered to each other on the rear side of the stop edge portion relative to the stretching direction, and hooking onto the stop edge portion during stretching and peeling.

Detailed Implementation

[0027] Hereinafter, preferred embodiments are listed, and the belt component and electronic device involved in the present invention will be described in detail with reference to the accompanying drawings.

[0028] Figure 1 This is a schematic top view of the electronic device 10 according to one embodiment, viewed from above. (Example) Figure 1 As shown, the electronic device 10 in this embodiment is a flip-type laptop PC, which is a structure in which the first housing 11 and the second housing 12 are connected in a way that allows them to rotate relative to each other via a hinge 14. In this embodiment, the electronic device 10 is an example of a laptop PC, but electronic devices other than laptop PCs may also be standalone display devices, tablet PCs, smartphones, or portable game consoles.

[0029] The second housing 12 is a flat box-like structure adjacent to the first housing 11. Inside the second housing 12 are various electronic components, including a motherboard housing a CPU, a battery, a memory, and an antenna. The keyboard 16 and touchpad 17 face the upper surface of the second housing 12.

[0030] The first housing 11 is a flat box that is thinner than the second housing 12. The first housing 11 is equipped with a display panel 18. Hereinafter, with respect to the first housing 11, based on the direction observed by the user when visually confirming the display surface 18a of the display panel 18, the left and right directions are referred to as X1 and X2 directions, the up and down directions are referred to as Y1 and Y2 directions, and the depth direction is referred to as Z1 and Z2 directions. Sometimes X1 and X2 directions are collectively referred to as the X direction, and the same terminology is sometimes used for Y1, Y2 and Z1, Z2 directions.

[0031] The display surface 18a of the display panel 18 faces the Z1 side surface (front 1a) of the first housing 11. The first housing 11 has a cover member 20 forming the Z2 side surface (back 11b) and a frame member 22 forming the peripheral portion of the front 11a. The top, bottom, left, and right sides of the first housing 11 are formed by vertical walls 23 that stand upright from the four peripheral portions of the cover member 20. The frame member 22 is a thin, frame-shaped sheet material surrounding the outer peripheral portion of the display panel 18. The front 11a of the first housing 11, including the frame member 22, is covered by touch glass 24. A hinge 14 is connected to the Y2 side edge (lower edge 11c) of the first housing 11.

[0032] The display panel 18 is composed of, for example, a liquid crystal display (LCD) or an organic EL display (OLED). The display panel 18 is constructed by stacking layers such as glass, a liquid crystal layer, and a light guide plate, and fixing the outer peripheries of each layer together using double-sided tape, adhesive, or the like. The touch glass 24 covers the display surface 18a, thereby forming a touch panel that receives touch operations on the display panel 18.

[0033] Next, a more detailed description of the structure of the first housing 11 will be provided.

[0034] Figure 2 This is a schematic front view of the first housing 11. Figure 2 The touch glass 24 and the bezel component 22 are omitted from the illustration; the display panel 18 is shown only by its outline indicated by double-dotted lines. In other words... Figure 2 The figure shows the inner surface 20a (the inner surface of the back side 11b) of the cover member 20 and the belt member 26 bonded to the inner surface 20a.

[0035] like Figure 2 As shown, the cover member 20 has a pair of left and right hinge mounting portions 20b formed by opening a notch in the vertical wall 24a of a portion of the lower edge 11c. The hinge mounting portions 20b are equipped with hinges 14. The hinge mounting portions 20b also serve as paths for wiring connecting the display panel 18 to the motherboard and the like inside the second housing 12.

[0036] For example, a pair of left and right strap members 26A and 26B are provided on the inner surface 20a of the cover member 20. The strap members 26A and 26B are adhesive tapes used to fix the display panel 18 relative to the cover member 20. The number of double-sided adhesive tapes provided can be one or more. Although the strap members 26A and 26B in this embodiment have different shapes and arrangements, they perform the same or identical functions and effects. Therefore, hereafter, the strap members 26A and 26B will be collectively referred to as strap member 26 without distinction between the two.

[0037] The mounting structure of the display panel 18 relative to the cover member 20 will be described.

[0038] Figure 3 This is a schematic side sectional view illustrating the structure in which the display panel 18 is secured to the cover member 20 using the strap member 26. Figure 2 as well as Figure 3 As shown, the belt member 26 has a double-sided adhesive tape 28 and a handle member 30.

[0039] Double-sided adhesive tape 28 bonds and fixes the inner surface 18b of the display panel 18, opposite to the display surface 18a, to the inner surface 20a of the cover member 20. The double-sided adhesive tape 28 has the property of being stretchable and peelable by stretching the end 28a, and is, for example, a component referred to as a stretch-peel tape, stretch double-sided tape, or pull tape.

[0040] like Figure 2As shown, in this embodiment, the first housing 11 is structured to fix the position near the Y1 side end of the display panel 18 to the inner surface 20a using double-sided adhesive tape 28. Here, for the first housing 11, the front side 11a is covered by the touch glass 24, and the back side 11b is covered by the cover member 20. Therefore, in the first housing 11, the space for the handle when pulling and peeling off the double-sided adhesive tape 28 is not limited to the lower edge 11c where the hinge mounting portion 20b is provided. Therefore, it is also considered that the double-sided adhesive tape 28 extends from the position near the Y1 side end of the display panel 18 to the hinge mounting portion 20b.

[0041] However, due to the high cost of components, it is desirable to minimize the amount of double-sided adhesive tape 28 used. Furthermore, the double-sided adhesive tape 28 is cut from large sheets of material into a specified shape, but for example... Figure 2 For the long L-shaped strip member 26 shown, the number of material sheets removed is reduced, thus further increasing the component cost. Furthermore, due to its thickness, the double-sided adhesive tape 28 is sometimes difficult to extend a long distance between the inner surface 18b of the display panel 18 and the inner surface 20a of the cover member 20.

[0042] Therefore, in this embodiment, the tape member 26 has a structure in which a handle member 30 is installed at the end 28a of the double-sided adhesive tape 28, and the double-sided adhesive tape 28 is stretched and peeled off by stretching the handle member 30. The handle member 30 is a sheet-like member that is thinner than the double-sided adhesive tape 28. The first end 30a of the handle member 30 is bonded and fixed between the inner surface 18b and the inner surface 20a and the end 28a. The second end 30b of the handle member 30 extends to a position extending to the side 18c of the display panel 18. This second end 30b becomes the part that is actually held by a tool or a person's hand when stretching and peeling off the double-sided adhesive tape 28.

[0043] Therefore, for the electronic device 10 of this embodiment, when removing the display panel 18 from the cover member 20, for example, the hinge 14 is removed and the first housing 11 is removed from the second housing 12. At this time, the wiring between the display panel 18 and the motherboard, etc., is also removed. Next, the second end 30b of the handle member 30 exposed at the hinge mounting portion 20b is grasped, and the double-sided adhesive tape 28 can be stretched and peeled off by stretching it in the Y2 direction. As a result, the display panel 18 is smoothly removed from the cover member 20.

[0044] Next, a specific structural example with component 26 will be described.

[0045] Figure 4 It is a schematic exploded perspective view of the mounting part and the surrounding part of the double-sided adhesive tape 28 and the handle component 30. Figure 5 This is a schematic top view with an enlarged view of the mounting portion and surrounding area of ​​the double-sided adhesive tape 28 and the handle component 30, omitting the illustration of the first adhesive sheet 34 of the handle component 30. Figure 6A It is along Figure 5 A schematic cross-sectional view of the VIA-VIA line. Figure 6B It means stretching. Figure 6A The schematic cross-sectional view shown illustrates the action of the handle component 30 in stretching and peeling off the double-sided adhesive tape 28.

[0046] like Figures 4 to 6A As shown, a pair of stop flanges 32 are formed at the end 28a of the double-sided adhesive tape 28. Each stop flange 32 is a part of the inner circumferential surface of a notch 33 formed by a notch made along the central direction on the side of the double-sided adhesive tape 28. Each stop flange 32 faces the opposite side to the end face 28a1 of the end 28a with respect to the stretching direction D1 when the double-sided adhesive tape 28 is stretched and peeled off. A residual portion 28b containing the double-sided adhesive tape 28 is formed between each stop flange 32 and the end face 28a1.

[0047] Each stop edge 32 is provided on the left and right sides, separated by the center of the double-sided adhesive tape 28 in the width direction, forming a left-right symmetrical shape. Each stop edge 32 is an edge extending in a direction intersecting the stretching direction D1. Specifically, each stop edge 32 extends in a direction opposite to the stretching direction D1, along an inclined direction D2 that gradually slopes outward from the center of the double-sided adhesive tape 28 in the width direction. Therefore, when viewed with the center of the double-sided adhesive tape 28 in the width direction as a reference, the inclined direction D2 is a direction that slopes in the opposite direction to the stretching direction D1, compared to the orthogonal direction D3 which is orthogonal to the stretching direction D1. Thus, when viewed from above, the end 28a of the double-sided adhesive tape 28 has a roughly anchor-shaped form. In this case, the end 28a extends from the end face 28a1 of the double-sided adhesive tape 28 towards the stretching direction D1 within a predetermined range, for example, about 10 mm. The end face 28a can be less than 10 mm or more than 10 mm. The stop edge portion 32 may only have one on the left and one on the right, omitting the other. The stop edges 40, 42, 48, 54, 56, and 58 involved in the modified examples described later can also be provided in the same way. In addition, for example, when the width of the double-sided adhesive tape 28 is 8 mm, the stop edge portion 32 can be configured such that its width along the orthogonal direction D3 is about 2 mm, and its length along the stretching direction D1 is about 2 mm.

[0048] like Figures 4 to 6A As shown, the handle component 30 has a first adhesive sheet 34 and a second adhesive sheet 35.

[0049] Adhesive sheets 34 and 35 are single-sided adhesive tapes. Adhesive sheets 34 and 35 are configured such that their first end 30a overlaps with the end 28a of the double-sided adhesive tape 28 in the tensile direction D1, and are positioned to sandwich the end 28a from above and below. For the first adhesive sheet 34, the adhesive surface 34a is bonded to the first adhesive surface 28c of the double-sided adhesive tape 28, thereby covering the first adhesive surface 28c of the end 28a. For the second adhesive sheet 35, the adhesive surface 35a is bonded to the second adhesive surface 28d of the double-sided adhesive tape 28, thereby covering the second adhesive surface 28d of the end 28a. In the portions of adhesive sheets 34 and 35 not bonded to adhesive surfaces 28c and 28d, the adhesive surfaces 34a and 35a of each other are adhered to each other.

[0050] The adhesive sheets 34 and 35 also cover the stop edge portion 32 and its surrounding area of ​​the double-sided adhesive tape 28. Here, the double-sided adhesive tape 28 has a notch 33 behind the stop edge portion 32 in the stretching direction D1. The adhesive sheets 34 and 35 have hook portions 36 where the adhesive surfaces 34a and 35a pass through the notch 33 and are attached to each other. The hook portions 36 are respectively disposed on the rear side of each stop edge portion 32 in the stretching direction D1.

[0051] Next, the action of stretching and peeling the double-sided adhesive tape 28 via the handle member 30 and the effect of the tape member 26 will be explained.

[0052] like Figure 6A as well as Figure 6B As shown, when stretching and peeling the double-sided adhesive tape 28, the second end 30b of the handle member 30 is held by a tool or a person's hand and stretched in the stretching direction D1. Thus, the double-sided adhesive tape 28 is stretched in the stretching direction D1 by the handle member 30. Consequently, the double-sided adhesive tape 28 becomes thinner in the stretching direction D1, gradually tapering from the beginning end 28a side (see reference). Figure 6B The adhesive surfaces 28c and 28d are peeled off from the inner surface 18b of the display panel 18 and the inner surface 20a of the cover member 20. The strap member 26 can pull the double-sided adhesive tape 28 peeled off from the inner surface 18b and the inner surface 20a to the side of the display panel 18 by further stretching the handle member 30.

[0053] However, as described above, in this embodiment, the first housing 11 is positioned significantly away from the side 18c of the display panel 18 due to the double-sided adhesive tape 28 (see reference). Figure 2Therefore, the handle component 30 is long, and the pull-out distance of the double-sided adhesive tape 28 based on the handle component 30 is also long. In such a structure, as in the prior art described above, when the handle component 30 is only attached to the double-sided adhesive tape 28 by adhesive force, there is a possibility that the fixed parts will detach during the pull-out action. In this case, the double-sided adhesive tape 28 remains on the inner surface 18b side of the display panel 18, making it difficult to remove the display panel 18. On the other hand, in the structure where the handle component 30 is only attached to the double-sided adhesive tape 28 by adhesive force, if the overlap distance between the handle component 30 and the double-sided adhesive tape 28 is ensured to be quite large, the detachment of the handle component 30 can be suppressed. However, in this case, the actual adhesive surfaces 28c and 28d of the double-sided adhesive tape 28, in other words, the area where the display panel 18 is bonded to the cover component 20, is reduced, and the adhesive strength of the display panel 18 is reduced.

[0054] In this respect, the tape member 26 of this embodiment has a stop flange 32 at the end 28a of the double-sided adhesive tape 28, and the hook portion 36 of the adhesive sheets 34 and 35 of the handle member 30, which are attached to each other, is located behind the stop flange 32 in the stretching direction D1. Therefore, as Figure 6B As shown, when the adhesive surfaces 34a and 35a of the first end 30a side of the adhesive sheets 34 and 35 are peeled off from the adhesive surfaces 28c and 28d of the double-sided adhesive tape 28, the hook portion 36 also hooks onto the stop edge portion 32 to prevent it from detaching. In other words, the stop edge portion 32 is a structure that physically locks the hook portion 36, and can also be referred to as a barbed or undercut shaped portion.

[0055] As a result, for the electronic device 10, the double-sided adhesive tape 28 remains on the inner surface 18b side of the display panel 18, which can prevent the display panel 18 from being difficult to remove.

[0056] Here, in a comparative example where the handle member 30 is simply attached to the double-sided adhesive tape 28 by adhesive force, and in an embodiment having a stop edge portion 32 and a hook portion 36, experimental results comparing the stretching distance of the double-sided adhesive tape 28 until the handle member 30 detaches are described. The experiment was conducted with the double-sided adhesive tape 28 bonded to the inner surface 18b and the inner surface 20a, and the stretching distance from when the handle member 30 is held and stretched until it detaches from the double-sided adhesive tape 28 was measured. As a result of the experiment, in the comparative example, the handle member 30 detached at approximately 20 cm, while in the embodiment, the handle member 30 detached at approximately 55 cm. Therefore, the experiment also demonstrated the detachment suppression effect of the handle member 30 in the tape member 26 of this embodiment.

[0057] Furthermore, as described above, the double-sided adhesive tape 28 has the characteristic of becoming thinner in a manner that gradually tapers from the end 28a side to the front end during stretching and peeling (see reference). Figure 6B Therefore, the tape member 26 fixes the adhesive sheets 34 and 35 only by bonding them to the upper and lower adhesive surfaces 28c and 28d of the double-sided adhesive tape 28. Similar to the smooth peeling of the double-sided adhesive tape 28 from the inner surface 18b and inner surface 20a, the double-sided adhesive tape 28 can easily detach from the adhesive sheets 34 and 35. In this respect, the tape member 26 of this embodiment can prevent the handle member 30 from falling off the double-sided adhesive tape 28 through the physical locking action of the stop edge portion 32 and the hook portion 36.

[0058] In the tape member 26 of this embodiment, stop flanges 32 are respectively provided on the left and right sides, separated from the center of the double-sided adhesive tape 28 in the width direction, and hook portions 36 are respectively provided on the rear side of the left and right stop flanges 32 in the stretching direction D1. Therefore, the tape member 26 is respectively engaged with the left and right stop flanges 32 by the left and right hook portions 36, thereby further suppressing the occurrence of the handle member 30 falling off the double-sided adhesive tape 28. Furthermore, as Figure 5 As shown, if the left and right stop edges 32 are symmetrical in shape, the left and right hooks 36 can be well and evenly locked onto the left and right stop edges 32, which can further suppress the handle component 30 from falling off the double-sided adhesive tape 28. The same applies to the stop edges 40, 42, 48, 54, 56 and 58 described later.

[0059] The stop edge can also be excluded Figure 4 as well as Figure 5 The shape and structure other than the stop flange 32 shown are described below. Therefore, variations of the stop flange will be described in turn. In addition, in the stop flanges 40, 42, 44, 46, 48, 54, 56, and 58 described below, a hook portion 36 is also provided on its rear side in the stretching direction D1. As a result, in the structures involved in these variations, since the hook portion 36 hooks onto the stop flange 40, etc., and prevents detachment when the double-sided adhesive tape 28 is stretched and peeled off via the handle member 30, the handle member 30 can be prevented from detaching from the double-sided adhesive tape 28.

[0060] Figure 7 This is a schematic exploded perspective view showing the double-sided adhesive tape 28 of the stop edge portion 40 with the first modified example and the mounting portion and surrounding portion of the handle member 30 enlarged. Figure 7 In, with Figures 1 to 6B The reference numerals shown in the accompanying drawings denote the same or identical structures, and therefore serve the same or identical functions and effects. Detailed descriptions are omitted for the purposes of this document. Figures 8 to 14 The same.

[0061] and Figure 3 Compared to the stop edge 32 shown, Figure 7 The stop edge portion 40 shown extends in a different direction. The stop edge portion 40 extends along an orthogonal direction D3, which is orthogonal to the stretching direction D1. As a result, when viewed from above, the end 28a of the double-sided adhesive tape 28 becomes approximately hammer-shaped. With such a stop edge portion 40, the hook portion 36 disposed behind it in the stretching direction D1 can also be prevented from detaching.

[0062] Among them, compared with the stop flange portion 40 along the orthogonal direction D3, the stop flange portion 32 along the inclined direction D2 can more reliably lock the hook portion 36 during stretching and peeling. On the other hand, the stop flange portion 40 has a simpler shape than the stop flange portion 32, and it is also easier to ensure the area of ​​the notch portion 33. Therefore, the formation of the hook portion 36 is easy and reliable.

[0063] Figure 8 This is a schematic exploded perspective view showing the double-sided adhesive tape 28 of the stop flange portion 42 with the second modified example and the mounting portion and surrounding portion of the handle component 30 enlarged.

[0064] Figure 8 The stop edge portion 42 shown differs from the straight stop edges 32 and 40 described above; it is curved in an arc shape. Therefore, when viewed from above, the end 28a of the double-sided adhesive tape 28 becomes approximately spoon-shaped. Each stop edge portion 42, when viewed with the center of the width direction of the double-sided adhesive tape 28 as a reference, is inclined towards the stretching direction D1 rather than the orthogonal direction D3. With such stop edge portions 42, the hook portion 36 positioned behind it in the stretching direction D1 can also be prevented from detaching.

[0065] The stop edge 42 has a shape that gradually curves outward from the center of the double-sided adhesive tape 28 in the width direction toward the stretching direction D1. Therefore, compared with the stop edges 32 and 40 described above, the hook part 36 is easier to detach in the stretching direction D1. Therefore, considering the locking effect of the hook part 36, it is preferable to have a shape along the orthogonal direction D3 or along the inclined direction D2, like the stop edges 32 and 40 described above, compared with the stop edge 42. On the other hand, the stop edge 42 has a simpler shape than the stop edges 32 and 40, and it is also easier to ensure the area of ​​the notch 33. Therefore, the formation of the hook part 36 is easy and reliable.

[0066] Figure 9 This is a schematic exploded perspective view showing the double-sided adhesive tape 28 of the stop flange portion 44 with the third modified example and the mounting portion and surrounding portion of the handle component 30 enlarged.

[0067] Figure 9 The stop edge 44 shown is not as Figure 3 Instead of being formed through a notch 33 as shown in the diagram, the stop edge 32 is formed through a through hole 45. The through hole 45 is a hole that passes through the double-sided adhesive tape 28 in the thickness direction, and is, for example, elliptical. The stop edge 44 is the inner peripheral edge of the through hole 45. Thus, the stop edge 44 has a shape that gradually curves outward from the center of the width direction of the double-sided adhesive tape 28 in the direction opposite to the stretching direction D1. It is preferable that the hook portion 36 passes through the through hole 45 to adhere the adhesive sheets 34 and 35 to each other. Therefore, with such a stop edge 44, the hook portion 36 located behind it in the stretching direction D1 can also be prevented from detaching.

[0068] Figure 10 This is a schematic exploded perspective view showing the double-sided adhesive tape 28 of the stop flange portion 46 with the fourth modification and the mounting portion and surrounding portion of the handle component 30 enlarged.

[0069] Figure 10 The stop flange 46 shown is for Figure 7 The stop edge 40 shown is provided only on one side. The stop edge 46 extends along an orthogonal direction D3, which is orthogonal to the stretching direction D1. Thus, when viewed from above, the end 28a of the double-sided adhesive tape 28 becomes approximately hook-shaped or claw-shaped. With such a stop edge 46, the hook portion 36 disposed behind it in the stretching direction D1 can also be prevented from detaching.

[0070] Figure 11 This is a schematic exploded perspective view showing the double-sided adhesive tape 50 of the stop flange portion 48 with the fifth modified example and the mounting portion and surrounding portion of the handle member 30 enlarged.

[0071] Figure 11 The double-sided adhesive tape 50 shown is similar to the double-sided adhesive tape 28 described above, except that its width is approximately twice that of the tape. The stop edge portion 48 is the inner peripheral edge of two through holes 52 arranged in the width direction of the double-sided adhesive tape 50. It is preferable that the hook portion 36 passes through each through hole 52 to adhere the adhesive sheets 34 and 35 together to form a pair. The shape of the stop edge portion 48 is similar to... Figure 9 The stop edge portion 44 shown is the same or identical. Therefore, with such a stop edge portion 48, the hook portion 36 disposed behind it in the stretching direction D1 can also be prevented from detaching.

[0072] exist Figure 11 In the structural example shown, notches 33 are formed on the left and right sides of the double-sided adhesive tape 50, and stop flanges 54 are also formed at these locations. The stop flanges 54 are... Figure 8The stop edge portion 42 shown has the same shape, and a hook portion 36 is provided on its rear side to prevent it from falling off. In other words, the wide double-sided adhesive tape 50 forms, for example, four stop edges 48, 48, 54, 54 arranged from left to right, which can make the handle component 30 more securely prevent it from falling off.

[0073] Figure 12 This is a schematic exploded perspective view showing the double-sided adhesive tape 50 of the stop flange portion 56 with the sixth modified example and the mounting portion and surrounding portion of the handle member 30 enlarged.

[0074] Figure 12 The stop flange 56 shown is provided side by side with the double-sided adhesive tape 50. Figure 7 The structure shown is the same as that of a pair of stop flanges 56. Therefore, in this structural example, the four stop flanges 56, which are arranged left and right with hook portions 36 disposed on their rear sides in the stretching direction D1, can reliably prevent detachment.

[0075] Figure 13 This is a schematic exploded perspective view showing the double-sided adhesive tape 50 of the stop flange portion 58 with the 7th modified example and the mounting portion and surrounding portion of the handle member 30 enlarged.

[0076] Figure 13 The stop edge portion 58 shown is provided with a pair of inner peripheral edges of rectangular through holes 60 formed on the left and right sides of the double-sided adhesive tape 50. Therefore, with such a stop edge portion 58, the hook portion 36 disposed behind it in the stretching direction D1 can also be prevented from detaching.

[0077] like Figure 14 As shown, double-sided adhesive tape 50 can also replace... Figure 13 The pair of through holes 60 shown are used, while a slit-shaped through hole 62 is used to extend in the long side direction of the double-sided adhesive tape 50, and a stop edge portion 58 is formed on its inner periphery.

[0078] Furthermore, the present invention is not limited to the above-described embodiments, and it is self-evident that it can be freely modified within the scope of the spirit of the present invention.

[0079] The above example illustrates a structure in which the display panel 18 is fixed by the strap member 26, but the strap member 26 can also be used to fix various components that need to be removed, in addition to the display panel 18.
