Description

Technical Field

[0001] The present invention relates to an electronic device. Background Art

[0002] For example, Japanese Patent Gazette No. 2013-182767 discloses a portable telephone comprising: a battery holder that accommodates a battery pack and is fixed by an adhesive; and a battery removal piece that is provided on the battery holder and has one end that passes through a slit provided on a battery pack setting surface to route wiring from the battery pack setting surface to the back side of the battery pack setting surface.

[0003] In the above-mentioned portable phone, the battery removal tab is provided at the other end thereof, and the battery pack is removed from the battery holder by pulling a tab extending from an opening opposite to the battery pack mounting surface of the battery holder in a direction perpendicular to the battery pack mounting surface to peel off the adhesive from the battery pack. Summary of the Invention

[0004] Technical problems to be solved by the present invention

[0005] In the electronic device (cellular phone) described above, when the tab is pulled, pressure is applied to the portion of the battery pack near the tab, and there is a concern that the battery pack may be deformed and become unusable.

[0006] Therefore, for example, a method has been adopted in which an electronic component such as a battery pack is fixed to a housing on which the electronic component is mounted using an adhesive sheet, and a tab provided on the adhesive sheet is pulled to peel off the adhesive sheet and remove the electronic component.

[0007] In the above-mentioned method, the adhesive sheet is generally formed into a strip with a substantially constant width and arranged to extend along the outer shape of the electronic component. Therefore, if the adhesive sheet is bent along the corner of the electronic component, the sheet may become entangled in the bent portion when the tab is used to pull the adhesive sheet. If the adhesive sheet becomes entangled, it may be cut off in the bent portion, leaving residue, which may damage the electronic component or prevent removal.

[0008] Therefore, an object of one aspect of the present invention is to provide an electronic device that can be easily removed without damaging electronic components, for example.

[0021] The following describes various embodiments of the present invention with reference to the accompanying drawings. In this specification and the accompanying drawings, identical or equivalent elements are assigned the same reference numerals to avoid duplication of description. Elements not directly related to the present invention may be omitted from the illustrations. The configurations of the components shown in these embodiments are illustrative only and are not intended to be limiting.

[0022] Below, use Figures 1 to 3 , an electronic device 100 according to one aspect of the present invention will be described. The electronic device 100 is, for example, a smartphone. The electronic device 100 is not limited to smartphones, and may be, for example, a foldable mobile phone, a wearable terminal, a tablet terminal, or any other electronic device as long as it includes a display unit 110 (described later). Figure 1 It is a front view of the electronic device 100. Figure 2 is a rear view of the electronic device 100 . Figure 3 1 is an exploded perspective view of the electronic device 100. Figure 3 In the following description, the substrate and rear cover 130 attached to the housing 120 are omitted from the illustration. In the following description, the length direction of the display unit 110 (described later) is defined as the up-down direction, the width direction of the display unit 110 is defined as the left-right direction, and the thickness direction of the display unit 110 is defined as the front-back direction. Furthermore, in the electronic device 100, the side on which the display unit 110 is provided is defined as the front side. However, these directions are defined for convenience of description and are not intended to define the orientation during use.

[0023] The electronic device 100 has, for example, a flat outer shape that is substantially rectangular when viewed from the front. The electronic device 100 includes, for example, a display unit 110 , a housing 120 , and a back cover 130 .

[0024] The display unit 110 is formed, for example, in a substantially rectangular shape when viewed from the front. The display unit 110 includes a display panel 111 capable of displaying an image, and a cover plate 112 disposed so as to overlap the front surface of the display panel 111. The display panel 111 is, for example, a panel including an OLED (Organic Light Emitting Diode) as a self-luminous element. The cover plate 112 covers the front surface of the display panel 111. The cover plate 112 is, for example, provided integrally with the touch panel.

[0025] The display panel 111 includes an OLED (Organic Light Emitting Diode) as a self-luminous element, but is not limited to this. For example, it may include a QLED (Quantum Dot Light Emitting Diode). Furthermore, the display panel 111 is not limited to a panel having a self-luminous element and may be, for example, a liquid crystal panel (LCD). Furthermore, the cover plate 112 is provided integrally with the touch panel, but is not limited to this. It may also be composed solely of a glass panel or an organic glass panel.

[0026] The housing 120 is formed in a substantially rectangular flat plate shape. The peripheral edge of the housing 120 protrudes forward and backward. The housing 120 is made of resin or metal.

[0027] The display unit 110 is mounted on the front of the housing 120. The display unit 110 is embedded in the peripheral portion of the housing 120 so as to cover substantially the entire front surface of the housing 120. Specifically, the display panel 111 is disposed on the front surface of the housing 120, for example, with space left in the vertical direction. The cover plate 112 is disposed so as to cover substantially the entire front surface of the housing 120.

[0028] A substrate (not shown) and a rechargeable battery 124 are installed on the back of the housing 120. The substrate (not shown) and the rechargeable battery 124 are installed with various electronic components that constitute the electronic device 100 (for example, the first camera module 121, the second camera module 122, the earpiece 123, etc. described later).

[0029] A first camera module 121 is disposed at the center of the upper end of the housing 120 (see Figure 4 ). The first camera module 121 is configured so that the shooting direction is forward. The first camera module 121 is a front camera. The first camera module 121 includes, for example, a camera 121a including a color image sensor, a lens, etc., and a proximity sensor 121b. In the center of the upper end of the housing 120, a camera 121a is configured on the left side, and a proximity sensor 121b is configured on the right side. The proximity sensor 121b detects the presence of an approaching object within a specified range close to the proximity sensor 121b. The electronic device 100 uses the proximity sensor 121b, for example, to suppress malfunctions of applications.

[0030] The second camera module 122 is disposed at the center of the upper side of the housing 120, more specifically, below the first camera module 121 (see Figure 4 The second camera module 122 is configured with the camera direction facing backward. The second camera module 122 is a rear camera.

[0031] An earpiece 123 is arranged on the right side of the upper end of the housing 120 (see Figure 4 The receiver 123 plays a sound based on a sound signal input from the control unit.

[0032] The rechargeable battery 124 is arranged from the center to the bottom of the rear of the housing 120 (see Figure 4 The rechargeable battery 124 functions as a power source for the electronic device 100. The rechargeable battery 124 is a rechargeable battery such as a lithium-ion battery. A partition 124a for the rechargeable battery 124 is disposed at the center of the lower side of the housing 120.

[0033] The rear cover 130 is formed, for example, in a substantially rectangular shape when viewed from the front. It is attached to the rear of the housing 120. The rear cover 130 is embedded in the periphery of the housing 120 so as to cover substantially the entire rear surface of the housing 120. An opening is formed in the rear cover 130 for exposing the second camera module 122 to the outside.

[0034] use Figures 3 to 5 , the adhesive sheet 140 will be described. Figure 3 1 is an exploded perspective view of the electronic device 100. Figure 3 In the figure, the substrate and the back cover 130 mounted on the housing 120 are omitted from the illustration. Figure 4 It is a front view of the housing 120 with the adhesive sheet 140 attached thereto. Figure 5 The first extension portion 141 Figure 4 A partial enlarged view of the .

[0035] like Figure 3 As shown, the adhesive sheet 140 is provided between the display unit 110 and the housing 120 , for example. That is, the adhesive sheet 140 fixes the display unit 110 and the housing 120 .

[0036] The adhesive sheet 140 is, for example, a long and narrow double-sided tape, and is configured so that the adhesive force of the adhesive sheet 140 is reduced by pulling the adhesive sheet 140 .

[0037] like Figure 4 As shown, adhesive sheet 140 has a shape that extends along the edge of the display unit 110 on the side of the display unit 110 that faces the housing 120. For example, adhesive sheet 140 is formed into a generally inverted U-shape that connects a pair of left and right sides of the display unit 110 with the top side. As described above, adhesive sheet 140 extends along three sides of the display unit 110, but this is not limiting; it only needs to extend along at least two adjacent sides of the display unit 110. Furthermore, adhesive sheet 140 extends along the edge of the display unit 110, but this is not limiting; for example, it may also be provided along the edge of the housing 120.

[0038] In this embodiment, the adhesive sheet 140 includes: a first extension portion 141 extending along the left side of the display unit 110, a first bent portion 142 bent from the left side to the upper side of the display unit 110, a second extension portion 143 extending along the upper side of the display unit 110, a second bent portion 144 bent from the upper side to the right side of the display unit 110, and a third extension portion 145 extending along the right side of the display unit 110.

[0039] The adhesive sheet 140, for example, has a plurality of pull tabs 150 for pulling the adhesive sheet 140. The pull tabs 150 serve as non-adhesive handles. The pull tabs 150, for example, are formed in a generally rectangular shape when viewed from the front. In this embodiment, the pull tabs 150 are provided on each of the extensions, more specifically, on the first extension 141, the second extension 143, and the third extension 145.

[0040] In addition, although it is preferable to provide one pull tab 150 in each extension part, it is not limited thereto and a plurality of pull tabs may be provided in each extension part, or only in a predetermined extension part among the plurality of extension parts.

[0041] The pull tab 150 is provided, for example, on the inner circumference of the adhesive sheet 140. The inner circumference of the adhesive sheet 140 refers to one side of the adhesive sheet 140 in the width direction. The width direction of the adhesive sheet 140 here refers to a direction perpendicular to the extension direction of the adhesive sheet 140. In this embodiment, the width direction of the first extension portion 141 and the third extension portion 145 refers to the left-right direction, while the width direction of the second extension portion 143 refers to the up-down direction. Specifically, in the first extension portion 141, the pull tab 150 is provided on the inner circumference located on the right side. In the second extension portion 143, the pull tab 150 is provided on the inner circumference located on the bottom side. In the third extension portion 145, the pull tab 150 is provided on the inner circumference located on the left side.

[0042] The housing 120 has an opening 151 at a position overlapping the pull tab 150 in the front-to-back direction, for pulling the pull tab 150 from the rear side of the housing 120. The opening 151 extends through the housing 120 in the front-to-back direction. For example, the opening 151 is formed so as to at least surround the pull tab 150 when viewed from the front-to-back direction. If there are multiple pull tabs 150, the opening 151 is provided at a position corresponding to each pull tab 150. Thus, when the back cover 130 is removed from the electronic device 100, the pull tab 150 can be pulled from the rear side of the housing 120 through the opening 151. Therefore, by pulling the pull tab 150 through the opening 151, the adhesive sheet 140 disposed between the display unit 110 and the housing 120 can be removed.

[0043] Adhesive sheet 140 has, for example, a plurality of cutouts 160 for cutting adhesive sheet 140 at predetermined locations. Cutouts 160 are configured to cut adhesive sheet 140 into portions corresponding to the respective extensions. In this embodiment, cutouts 160 are provided on the first curved portion 142 side of first extension 141 and on the second curved portion 144 side of second extension 143.

[0044] Cutout 160 is provided, for example, on the outer periphery of adhesive sheet 140. The outer periphery refers to the other side of adhesive sheet 140 in the width direction. Specifically, cutout 160 is located on the side of adhesive sheet 140 opposite to the side where tab 150 is provided. Specifically, in first extension 141, cutout 160 is provided on the outer periphery located on the left side. In second extension 143, cutout 160 is provided on the outer periphery located on the upper side.

[0045] In addition, the cutout portion 160 is provided on the outer peripheral side of the adhesive sheet 140, but is not limited thereto. It may also be provided on the side opposite to the side where the pull tab 150 is provided in the width direction of the adhesive sheet 140. For example, the cutout portion 160 may be provided on the inner peripheral side of the adhesive sheet 140, and the pull tab 150 may be provided on the outer peripheral side of the adhesive sheet 140.

[0046] like Figure 4 and Figure 5 As shown, the cutout portion 160 has a shape that is cut inward from the outer periphery of the adhesive sheet 140. For example, the cutout portion 160 has a convex shape that narrows inward from the outer periphery of the adhesive sheet 140. Furthermore, the cutout portion 160 has a shape that is inclined toward the nearby curved portion as it moves inward from the outer periphery of the adhesive sheet 140.

[0047] like Figure 5 As shown, in the first extension portion 141, the cutout portion 160 has a pair of sides extending inward from the outer periphery of the adhesive sheet 140. These sides are an upper side 160a located on the first curved portion 142 side, and a lower side 160b located on the opposite side of the first curved portion 142 side. Upper side 160a slopes toward the first curved portion 142 side (upper side) as it moves inward from the outer periphery of the first extension portion 141. Similarly, lower side 160b slopes toward the first curved portion 142 side (upper side) as it moves inward from the outer periphery of the first extension portion 141.

[0048] Similarly, in the second extension portion 143, the cutout portion 160 has a pair of sides extending inward from the outer periphery of the adhesive sheet 140. The pair of sides is a right side 160c located on the second curved portion 144 side and a left side 160d located on the opposite side of the second curved portion 144 side (see Figure 8 The right side 160c is inclined toward the second curved portion 144 (right side) as it moves downward from the outer periphery of the second extending portion 143. Similarly, the left side 160d is inclined toward the second curved portion 144 (right side) as it moves inward from the outer periphery of the second extending portion 143.

[0049] Below, use Figure 6 and Figure 7 The peeling of pressure-sensitive adhesive sheet 140 from pull tab 150 using first extending portion 141 will be described. Figure 6This is a front view of housing 120 showing adhesive sheet 140 being pulled using tab 150 of first extension portion 141 . Figure 7 It is a front view of the housing 120 showing the adhesive sheet 140 in a state where the first extension portion 141 is peeled off.

[0050] like Figure 6 As shown, the user pulls the tab 150 of the first extension portion 141 from the rear side of the housing 120 through the opening 151 to Figure 6 By pulling in the direction of the arrow (right direction) shown, the adhesive sheet 140 can be gradually peeled upward and downward from the portion of the first extension portion 141 near the pull tab 150. Then, by grasping the pull tab 150 or the peeled adhesive sheet 140 near the pull tab 150 and pulling it upward, for example, one end side (lower end side) of the adhesive sheet 140 can be peeled off. On the other hand, if the peeled adhesive sheet 140 near the pull tab 150 or the pull tab 150 is grasped and pulled downward, for example, and the adhesive sheet 140 is peeled off until it reaches the cutout portion 160, the stress is concentrated on the narrowed portion of the first extension portion 141 where the cutout portion 160 is formed, and the adhesive sheet 140 can be cut at the cutout portion 160. Therefore, as Figure 7 As shown, by pulling the tab 150 of the first extension portion 141 , only the portion of the adhesive sheet 140 corresponding to the first extension portion 141 can be peeled off.

[0051] Therefore, adhesive sheet 140 can be peeled off at each portion of adhesive sheet 140 corresponding to each side of display unit 110, preventing adhesive sheet 140 from becoming entangled in the curved portion connecting the extensions corresponding to the respective sides. Consequently, adhesive sheet 140 does not remain in the curved portion, making it easy to remove display unit 110 from housing 120 without damaging it. Furthermore, by providing cutout 160 on the side of adhesive sheet 140 opposite to the side where pull tab 150 is provided in the width direction of adhesive sheet 140, a narrowed portion of adhesive sheet 140 is provided on the side of first extension 141 where stress is most likely to act, i.e., the side where pull tab 150 is provided. This allows stress to be concentrated on this portion, thus reliably cutting adhesive sheet 140.

[0052] Furthermore, the notch 160 has a convex shape that narrows inward from the outer periphery, so that the front end (inner end E1) of the notch 160 can be formed into a shape that easily concentrates stress when the adhesive sheet 140 is pulled. Therefore, the stress can be concentrated on the narrowed portion of the adhesive sheet 140 where the notch 160 is formed, thereby cutting the adhesive sheet 140.

[0053] Furthermore, the cutout 160 has a shape that is cut out obliquely toward the first curved portion 142 located nearby as it moves inward from the outer periphery. This allows the width of the adhesive sheet 140 closer to the first curved portion 142 than the inner end E1 of the cutout 160 to be more rapidly increased than the width of the adhesive sheet 140 located at the inner end E1 of the cutout 160. Consequently, stress is concentrated on the narrowed portion of the adhesive sheet 140 located at the inner end E1 of the cutout 160, allowing the adhesive sheet 140 to be severed.

[0054] More specifically, by inclining lower edge 160b toward first curved portion 142, the angle formed between the outer edge of cutout 160 and lower edge 160b forms an obtuse angle. This allows the width of adhesive sheet 140 to gradually decrease from the outer edge of cutout 160 toward lower edge 160b. Therefore, when adhesive sheet 140 is pulled, it can be smoothly peeled toward inner end E1 of cutout 160. This allows stress to be concentrated at inner end E1 of cutout 160, i.e., the narrowed portion of adhesive sheet 140, allowing for reliable severance of adhesive sheet 140.

[0055] Furthermore, by tilting upper side 160a toward first curved portion 142, the angle formed between inner end E1 of cutout 160 and upper side 160a of cutout 160 becomes acute, thereby allowing the width of adhesive sheet 140 to increase sharply toward first curved portion 142 (upper side) relative to inner end E1 of cutout 160. Therefore, when adhesive sheet 140 is pulled, stress is concentrated at inner end E1 of cutout 160, i.e., at the narrowed portion of adhesive sheet 140, allowing adhesive sheet 140 to be reliably cut.

[0056] Furthermore, the cutout portion 160 provided in the second extension portion 143 also has the same configuration as the cutout portion 160 provided in the first extension portion 141 , and thus has the above-mentioned effects.

[0057] Below, use Figure 8 and Figure 9 , the second extension portion 143 is described. Figure 8 The second extension portion 143 is shown Figure 4 A partial enlarged view of the . Figure 9 The wide portion 143a is shown Figure 4 A partial enlarged view of the .

[0058] The second extension portion 143 extends in the left-right direction and includes a wide portion 143a surrounding the camera 121a, a left narrow portion 143b adjacent to the left side of the wide portion 143a, and a right narrow portion 143c adjacent to the right side of the wide portion 143a.

[0059] like Figure 8As shown, the wide portion 143a is disposed at the center of the upper end portion of the housing 120. The wide portion 143a is provided at a position corresponding to the first camera module 121.

[0060] The left narrow portion 143b is configured to have a smaller width (vertical length) than the wide portion 143a. The left narrow portion 143b extends in the left-right direction, connecting the first curved portion 142 and the wide portion 143a. More specifically, the left narrow portion 143b extends in the left-right direction, passing through the upper side between the first curved portion 142 and the wide portion 143a. In other words, the connection portion P1 between the left narrow portion 143b and the wide portion 143a is located at the upper side of the wide portion 143a in the width direction. In other words, the adhesive sheet 140 is formed to bulge downward from the left narrow portion 143b to the wide portion 143a.

[0061] The left narrow portion 143b is provided with a pull tab 150 for pulling the second extension portion 143. The pull tab 150 is provided on the inner peripheral edge of the left narrow portion 143b.

[0062] The right narrow portion 143c is configured to have a smaller width (vertical length) than the wide portion 143a. The right narrow portion 143c extends in the horizontal direction, connecting the wide portion 143a to the second curved portion 144. More specifically, the right narrow portion 143c extends in the horizontal direction between the wide portion 143a and the second curved portion 144, avoiding the earpiece 123 located on the upper side and passing through the lower side of the earpiece 123. In other words, the connection portion P2 between the right narrow portion 143c and the wide portion 143a is located near the lower side of the wide portion 143a in the width direction. In other words, the adhesive sheet 140 is formed to bulge upward from the right narrow portion 143c to the wide portion 143a. In addition, the right narrow portion 143c is located in the narrow space between the earpiece 123 and the second camera module 122, and therefore has a smaller width than the left narrow portion 143b.

[0063] The right narrow width portion 143c is provided with a notch 160 at the outer peripheral edge located on the upper side. The notch 160 is inclined toward the second curved portion 144 as it moves from the outer peripheral edge toward the inner side.

[0064] In the above configuration, the user moves the pull tab 150 of the left narrow width portion 143b toward the Figure 8By pulling in the direction of the arrow (downward), adhesive sheet 140 can be gradually peeled leftward and rightward from the portion of second extension 143 near tab 150. Then, by grasping tab 150 or the peeled adhesive sheet 140 near tab 150 and pulling it rightward, for example, one end (left end) of adhesive sheet 140 can be peeled to the portion of first extension 141 where cutout 160 is formed. On the other hand, by grasping tab 150 or the peeled adhesive sheet 140 near tab 150 and pulling it leftward, for example, adhesive sheet 140 is peeled through wide portion 143a to the right narrow portion 143c where cutout 160 is formed. Stress then concentrates on the narrowed portion of right narrow portion 143c where cutout 160 is formed, and adhesive sheet 140 can be severed at cutout 160. Therefore, by pulling the tab 150 of the second extension portion 143 , the portion of the adhesive sheet 140 corresponding to the second extension portion 143 , more specifically, the first curved portion 142 and the second extension portion 143 , can be peeled off.

[0065] Finally, by pulling tab 150 of third extension 145 of adhesive sheet 140, second curved portion 144 and third extension 145 can be separated from the portion of adhesive sheet 140 corresponding to third extension 145. More specifically, second curved portion 144 and third extension 145 can be separated. As described above, by pulling adhesive sheet 140 using tab 150 corresponding to each extension, adhesive sheet 140 can be cut for each portion corresponding to each extension.

[0066] like Figure 9 As shown, the wide portion 143 a has a first opening 170 and a second opening 180 . The first opening 170 exposes the camera 121 a toward the display unit 110 , and the second opening 180 exposes the proximity sensor 121 b toward the display unit 110 .

[0067] The longitudinal direction D1 of the first opening 170 is inclined relative to the left-right direction as it approaches the connecting portion P1 between the wide portion 143a and the left narrow portion 143b, as it moves toward the left narrow portion 143b, or in this embodiment, toward the left. In other words, the end of the first opening 170 on the left narrow portion 143b side is inclined relative to the left-right direction as it approaches the connecting portion P1.

[0068] As described above, by reducing the bonding area of ​​adhesive sheet 140 at connection portion P1 between wide portion 143a and left narrow portion 143b, the stress generated when pulling tab 150 and peeling adhesive sheet 140 is suppressed and concentrated at connection portion P1 before being transferred to wide portion 143a, thereby preventing adhesive sheet 140 from being torn off. Furthermore, by aligning the longitudinal direction D1 of first opening 170 with the direction in which adhesive sheet 140 is pulled within wide portion 143a (the direction of widening from left narrow portion 143b toward wide portion 143a, diagonally downward and to the right in this embodiment), first opening 170 is less likely to act as resistance when peeling adhesive sheet 140, thereby preventing adhesive sheet 140 from being torn off.

[0069] Furthermore, the connection portion P1 between the left narrow portion 143b and the wide portion 143a, and the connection portion P2 between the right narrow portion 143c and the wide portion 143a, are spaced apart in the width direction of the adhesive sheet 140. Specifically, the connection portion P1 is positioned near the upper side of the wide portion 143a, while the connection portion P2 is positioned near the lower side of the wide portion 143a. Consequently, the longitudinal direction D1 of the first opening 170 tilts toward the right narrow portion 143c, or right side in this embodiment, approaching the connection portion P2 between the wide portion 143a and the right narrow portion 143c. In other words, the end of the first opening 170 on the right narrow portion 143c side can tilt relative to the left-right direction so as to approach the connection portion P2.

[0070] Thus, first opening 170 can be positioned so that the end of first opening 170 on the left narrow portion 143b side is close to connection portion P1, and the end of first opening 170 on the right narrow portion 143c side is close to connection portion P2. This reduces the adhesive area of ​​adhesive sheet 140 near each connection portion, thereby suppressing stress concentration on each connection portion and preventing adhesive sheet 140 from being torn.

[0071] The first opening 170 is formed so that its opening area decreases as it approaches the right narrow width portion 143c. For example, the first opening 170 includes an arcuate portion 171 that covers a portion of the periphery of the camera 121a, and a pair of sides 172 connected to respective ends of the arcuate portion 171 and extending along the longitudinal direction D1 of the first opening 170. The pair of sides 172 are formed so that the distance between them becomes narrower as they approach the right narrow width portion 143c.

[0072] Right narrow portion 143c is farther from pull tab 150 than left narrow portion 143b and is narrower than left narrow portion 143b, making it easier to tear when peeling adhesive sheet 140. Therefore, first opening 170 is formed so that its opening area decreases as it approaches right narrow portion 143c. This prevents a sudden change in the adhesive area of ​​adhesive sheet 140 on the right narrow portion 143c side, thereby preventing adhesive sheet 140 from being torn.

[0073] The wide portion 143a has a second opening 180 between the first opening 170 and the right narrow portion 143c, exposing the proximity sensor 121b toward the display unit 110. The proximity sensor 121b is an electronic component that does not require coverage by the adhesive sheet 140. The proximity sensor 121b is covered by the adhesive sheet 140 near the right narrow portion 143c of the wide portion 143a. As a result, the adhesive area of ​​the adhesive sheet 140 gradually decreases as it moves toward the right narrow portion 143c. This reduces stress concentration at the connection point P2 between the right narrow portion 143c and the wide portion 143a, preventing the adhesive sheet 140 from tearing.

[0074] The second opening 180 is formed so that the thickness of the adhesive sheet 140 located around it is substantially constant. Specifically, the second opening 180 is formed so that the spacing from the outer periphery of the wide portion 143a, the spacing from the inner periphery of the wide portion 143a, the spacing from the end of the wide portion 143a on the right narrow portion 143c side, and the spacing from the first opening 170 are substantially constant.

[0075] That is, the second opening portion 180 includes: an upper side 180a arranged at a substantially fixed interval from the outer periphery of the wide portion 143a; a lower side 180b arranged at a substantially fixed interval from the inner periphery of the wide portion 143a; a left side 180c arranged at a substantially fixed interval from the first opening portion 170; and a right side 180d arranged at a substantially fixed interval from the right end portion of the wide portion 143a.

[0076] As described above, by setting the thickness of adhesive sheet 140 around second opening 180 to be substantially constant, the adhesive surface area gradually decreases toward right narrow width portion 143c, thereby preventing adhesive sheet 140 from being torn. Furthermore, by setting the spacing between first opening 170 (the side of the pair of sides 172 facing second opening 180) and second opening 180 (left side 180c) to be constant, tearing of adhesive sheet 140 can be prevented.

[0077] In addition, the long side direction D1 of the first opening portion 170 is inclined relative to the left and right directions in a manner that approaches the connecting portion P1 between the wide portion 143a and the left narrow portion 143b as it approaches the left narrow portion 143b where the pull tab 150 is provided, but is not limited to this. For example, when the pull tab 150 is provided in the right narrow portion 143c, it may also be inclined relative to the left and right directions in a manner that approaches the connecting portion P2 between the wide portion 143a and the right narrow portion 143c as it approaches the right narrow portion 143c.

[0078] In addition, the cutout portion 160 is arranged on the side of the first bend portion 142 of the first extension portion 141 and the side of the second bend portion 144 of the second extension portion 143, but is not limited thereto. For example, it can also be arranged on the side of the first bend portion 142 of the second extension portion 143 and the side of the second bend portion 144 of the third extension portion 145, or it can also be arranged on the side of the first bend portion 142 of the first extension portion 141 and the side of the second bend portion 144 of the third extension portion 145, or it can also be arranged on only one extension portion among multiple extension portions.

[0079] use Figure 10 , a first modification of the adhesive sheet will be described. Figure 10 140a is a front view of housing 120 showing a first modified example of an adhesive sheet. Adhesive sheet 140a, the first modified example, differs from adhesive sheet 140 in that right narrow portion 143c is provided with pull tab 150. Regarding adhesive sheet 140a, description of the same components as adhesive sheet 140 will be omitted.

[0080] The adhesive sheet 140a is provided with a pull tab 150 in the right narrow portion 143c. The pull tab 150 is provided in the right narrow portion 143c closer to the wide portion 143a than the cutout portion 160.

[0081] In the above configuration, by pulling tab 150 of right narrow portion 143c downward, the user can gradually peel adhesive sheet 140a leftward and rightward from the portion of second extension 143 near tab 150. Thus, by grasping tab 150 or the peeled adhesive sheet 140a near tab 150 and pulling it, for example, rightward, adhesive sheet 140a can be peeled through wide portion 143a and left narrow portion 143b to the portion of first extension 141 where cutout 160 is formed. On the other hand, by grasping tab 150 or the peeled adhesive sheet 140a near tab 150 and pulling it, for example, leftward, adhesive sheet 140a peels until it reaches cutout 160 of right narrow portion 143c. Stress concentrates on the narrowed portion of right narrow portion 143c where cutout 160 is formed, and adhesive sheet 140a can be severed at cutout 160. Therefore, by pulling the tab 150 of the second extension portion 143 , the portion of the adhesive sheet 140 a corresponding to the second extension portion 143 , more specifically, the first curved portion 142 and the second extension portion 143 , can be peeled off.

[0082] Furthermore, longitudinal direction D1 of first opening 170 is inclined relative to the left-right direction so as to approach connection point P2 between wide portion 143a and right narrow portion 143c as it approaches rightward toward right narrow portion 143c where tab 150 is provided. In other words, the end of first opening 170 on the right narrow portion 143c side is inclined relative to the left-right direction so as to approach connection point P2.

[0083] Furthermore, the longitudinal direction D1 of the first opening 170 is inclined relative to the left-right direction so as to approach the connection point P1 between the wide portion 143a and the left narrow portion 143b as it moves toward the left narrow portion 143b, or in this embodiment, toward the left. In other words, the end of the first opening 170 on the left narrow portion 143b side is inclined relative to the left-right direction so as to approach the connection point P1.

[0084] Thus, first opening 170 can be positioned so that the end of first opening 170 on the left narrow portion 143b side is close to connection portion P1, and the end of first opening 170 on the right narrow portion 143c side is close to connection portion P2. This reduces the adhesive area of ​​adhesive sheet 140a near each connection portion, thereby suppressing stress concentration on each connection portion and preventing adhesive sheet 140a from being torn.

[0085] In adhesive sheet 140a, pull tabs 150 are provided on both left narrow portion 143b and right narrow portion 143c. However, the present invention is not limited thereto. For example, pull tab 150 may be provided only on right narrow portion 143c.

[0086] The adhesive sheets 140 and 140 a are disposed between the display unit 110 and the housing 120 , but are not limited thereto. They may be disposed between the electronic component and the housing 120 . For example, they may be disposed between the rechargeable battery 124 and the housing 120 .

[0087] In the above configuration, the electronic device 100 includes an electronic component (display unit 110 in the above embodiment), a housing 120, an adhesive sheet 140, and a pull tab 150. The housing 120 is disposed opposite the electronic component. The adhesive sheet 140 includes two extensions (a first extension 141 and a second extension 143 in the above embodiment) and a curved portion (a first curved portion 142 in the above embodiment), and is disposed between the electronic component and the housing 120. The two extensions extend along two adjacent sides of the electronic component, respectively. The curved portion connects the two extensions. The pull tab 150 is disposed on one of the two extensions (the first extension 141 in the above embodiment) and is used to pull the adhesive sheet 140. The adhesive sheet 140 has a cutout 160 disposed on the curved portion (the first curved portion 142 in the above embodiment) of one of the extensions and on one side of the adhesive sheet 140 in the width direction. This allows adhesive sheet 140 to be peeled off for each portion of adhesive sheet 140 corresponding to each side of the electronic component, thereby preventing adhesive sheet 140 from becoming entangled at the curved portion connecting the extensions corresponding to the respective sides. Consequently, since adhesive sheet 140 does not remain at the curved portion, the electronic component can be easily removed from housing 120 without damaging it.

[0088] Furthermore, cutout 160 is provided on the side of adhesive sheet 140 opposite to the side where tab 150 is provided in the width direction. When tab 150 is pulled, stress is likely to act on the same side of one of the extensions as tab 150. Therefore, by providing cutout 160 as described above, a narrowed portion of adhesive sheet 140 is provided on the side of one of the extensions where stress is likely to act, concentrating stress on this portion and thus reliably cutting adhesive sheet 140.

[0089] Furthermore, the cutout 160 has a protruding shape that tapers from one side (the outer periphery in the above embodiment) to the other side (the inner side) in the width direction of the adhesive sheet 140. This allows the front end (inner end E1) of the cutout 160 to be shaped so that stress is easily concentrated when the adhesive sheet 140 is pulled. Consequently, stress is concentrated on the narrowed portion of the adhesive sheet 140 where the cutout 160 is formed, thereby cutting the adhesive sheet 140.

[0090] Furthermore, the cutout 160 is shaped so as to be cut from one side of the adhesive sheet 140 in its width direction (the outer peripheral side in the above embodiment) to the other side (the inner side in the above embodiment) and toward the curved portion (the first curved portion 142 in the above embodiment). This allows the width of the adhesive sheet 140 closer to the curved portion (the first curved portion 142) than the inner end E1 of the cutout 160 to be increased significantly compared to the width of the adhesive sheet 140 at the inner end E1 of the cutout 160. Consequently, stress is concentrated on the narrowed portion of the adhesive sheet 140 at the inner end E1 of the cutout 160, allowing the adhesive sheet 140 to be severed.

[0091] The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the above-described embodiment may be replaced with a configuration that is substantially the same as the configuration shown in the above-described embodiment, a configuration that produces the same function and effect, or a configuration that can achieve the same purpose.
