Abstract
Description
[Technical field]
[0001] The present invention relates to a protective case and a mobile terminal unit. [Background technology]
[0002] 2. Description of the Related Art Protective cases that include an elastic member and are attached to mobile terminals are known.
[0003] In this regard, Patent Document 1 describes a protective cover that includes a tray-shaped cover that is attached to one side of an electronic device body, and an elastic portion that continuously covers the outer and inner surfaces of the cover. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 5653321 Summary of the Invention [Problem to be solved by the invention]
[0005] However, in the invention described in Patent Document 1, the cover covering the back and sides of the electronic device body is made of a material harder than the elastic part. Therefore, the cover is less likely to deform than the elastic part, and it may be difficult to attach and detach the protective cover to and from the electronic device body. On the other hand, if the protective cover is made only of the elastic part, there is a problem in durability, such as deformation due to elongation occurring in the elastic part as the protective cover is attached to the electronic device and used.
[0006] An object of the present invention is to provide a protective case and a mobile terminal unit which are easy to attach to and detach from a mobile terminal and which are highly durable. [Means for solving the problem]
[0007] In order to solve the above problems, the protective case of the present invention is a protective case that is removably attached to a mobile terminal, and comprises a first case member formed of an elastic material and covering the rear side of the mobile terminal, and a second case member formed of a material having higher rigidity than the first case member, wherein the second case member is positioned in a central portion in the longitudinal direction of the mobile terminal and includes a strip-shaped region extending in the short direction of the mobile terminal, and the strip-shaped region is positioned on the opposite side of the first case member from the side covering the rear side of the mobile terminal.
[0008] Moreover, the mobile terminal unit of the present invention is a mobile terminal unit comprising a protective case and a mobile terminal to which the protective case is removably attached, wherein the protective case comprises a first case member formed of an elastic material and covering a rear side of the mobile terminal, and a second case member formed of a material having higher rigidity than the first case member, the second case member being arranged in a central portion in the longitudinal direction of the mobile terminal and including a strip-shaped region extending in the short direction of the mobile terminal, the strip-shaped region being arranged on the opposite side of the first case member to the side covering the rear side of the mobile terminal. Effect of the Invention
[0009] According to the present invention, it is possible to provide a protective case and a mobile terminal unit that are easy to attach to and detach from a mobile terminal and have high durability. [Brief description of the drawings]

As shown in FIG. 4, the key input unit 5 includes a power button 5b on the right side surface of the device case 1. The power button 5b receives inputs of power on / off from the user. As shown in FIGS. 2 to 4, the key input unit 5 includes trigger keys 5c on the right and left sides of the device case 1. The trigger keys 5c receive, for example, inputs of scanning execution of the scanner unit 6 from the user.
[0018] 5, the scanner unit 6 is provided on the top surface of the device case 1, which is the end surface of the lower case 3 located on one end 1a side of the device case 1. The scanner unit 6 reads a code symbol (e.g., a barcode) that is a subject, decodes the obtained signal, and outputs the signal to the control unit. At least a part of the decoding process of the code symbol reading result may be executed by the control unit. For example, the user points the scanner unit 6 of the mobile terminal 100 so as to face the code symbol, and the user presses the trigger key 5c to read the code symbol.
[0019] As shown in Fig. 3, the camera unit 71 and the LED 72 are provided on the back surface of the device case 1, i.e., the bottom surface of the lower case 3. The camera unit 71 has an optical system and an imaging element, and captures an image of a subject to generate image data. The camera unit 71 captures an image of, for example, a two-dimensional code. The LED 72 is provided in the vicinity of the camera unit 71, and irradiates light onto the subject of the camera unit 71.
[0020] As shown in FIG. 3, the battery lid 8 is provided on the lower surface of the lower case 3 and closes the battery housing section 10 (see FIG. 7) in the lower case 3 in an openable and closable manner. As shown in FIGS. 4, 6, and 7, the battery lid 8 has a shape that protrudes downward in accordance with the shape of the battery pack 200 housed in the battery housing section 10. As shown in FIG. 3, when the battery lid 8 is placed in the lower case 3 to close the battery housing section 10, the other end 8b of the battery lid 8 on the other end 1b side of the device case 1 is engaged with the edge of the battery housing section 10, and one end 8a of the battery lid 8 on the one end 1a side of the device case 1 is placed on the edge of the battery housing section 10. In this case, when the battery lid 8 is placed in the lower case 3 to close the battery housing section 10, the one end 8a is locked by the lock lever 9.
[0021] As shown in Fig. 3, the lock levers 9 are provided on the lower case 3 at positions located near both sides of one end 8a of the battery lid 8. The lock levers 9 include a substantially circular lock portion 9a and a lever portion 9b. The lock portion 9a is rotatably provided on the lower case 3 and detachably locks the one end 8a of the battery lid 8. The lever portion 9b extends from the lock portion 9a toward the one end 1a of the device case 1 and rotates the lock portion 9a.
[0022] 3, the lock lever 9 is disposed in a substantially sector-shaped lever storage portion 3a provided in the lower case 3. That is, the lock lever 9 is configured such that the lock portion 9a is rotatably provided at a required position in the sector-shaped lever storage portion 3a, and the lever portion 9b swings within the sector-shaped lever storage portion 3a.
[0023] As a result, when the lock lever 9 is placed in the lower case 3 with the battery lid 8 covering the battery storage section 10 of the lower case 3, as shown in Figure 3, and the lever portion 9b is swung within the lever storage section 3a to rotate the lock portion 9a in one direction, the lock portion 9a presses one end 8a of the battery lid 8 against the edge of the battery storage section 10 to lock it.
[0024] In addition, the lock lever 9 is configured such that when the lock portion 9a locks one end 8a of the battery lid 8, the lock of one end 8a of the battery lid 8 by the lock portion 9a is released by swinging the lever portion 9b in the opposite direction to rotate the lock portion 9a in the opposite direction.
[0025] 7, the battery accommodating section 10 is provided on the lower surface of the lower case 3, and accommodates the battery pack 200. The battery accommodating section 10 is formed to have approximately the same size as the battery pack 200.
[0026] 6, the connection electrode unit 11 is provided on the bottom surface, which is the end surface of the lower case 3 located on the other end 1b side of the device case 1. The connection electrode unit 11 has a plurality of arranged electrodes 11a, and is electrically connected to an external device (not shown) such as a charging stand to transmit and receive information and charge the battery pack 200 in the battery housing unit 10.
[0027] As shown in FIG. 7, the wireless communication antenna 12 is disposed in the device case 1 at the other end 1b side in the longitudinal direction of the device case 1. Specifically, the wireless communication antenna 12 is disposed in the device case 1 between the other end 8b of the battery cover 8 and the other end 1b of the device case 1 in the longitudinal direction of the device case 1. The wireless communication antenna 12 is an antenna member for wireless communication. The wireless communication antenna 12 is, for example, an antenna for a wide area network (WAN). As shown in FIG. 8, the wireless communication antenna 12A is disposed in the device case 1 at the right end of one end 1a side in the longitudinal direction of the device case 1. The wireless communication antenna 12A is, for example, an antenna for a wireless local area network (WLAN) or a global positioning system (GPS). As shown in FIG. 8, the wireless communication antenna 12B is disposed in the device case 1 at the left end of one end 1a side in the longitudinal direction of the device case 1. The wireless communication antenna 12B is, for example, an antenna for diversity. The wireless communication antennas 12A and 12B are other antenna members for wireless communication. The frequency characteristics of the wireless communication antennas 12, 12A, and 12B are set in accordance with the material of the device case 1. The device case 1 is formed from a material having a predetermined dielectric constant at least in the portions corresponding to the wireless communication antennas 12, 12A, and 12B in the thickness direction (vertical direction) of the device case 1. The control unit of the mobile terminal 100 communicates with external devices on a communication network (not shown) via the wireless communication antennas 12, 12A, and 12B.
[0028] The label 13 (see FIG. 3) is a label on the underside of the lower case 3 on which information about the mobile terminal 100 is written. The IF unit 14 is provided on the right side of the device case 1, and is an interface for transmitting and receiving data to and from an external device. The standard of the IF unit 14 is, for example, USB (Universal Serial Bus). The IF unit 14 may also have a general earphone jack. The speaker 15 is provided on the underside of the lower case 3, and outputs voice or sound effects. The belt attachment part 16 is provided on the underside of the lower case 3, and is configured so that one end of a hand belt can be attached thereto.
[0029] 7, the battery pack 200 includes a connection terminal 201 at a front end 200a of the battery pack 200. When the battery pack 200 is accommodated in the battery accommodating section 10, the connection terminal 201 is electrically connected to a connection terminal on the battery accommodating section 10 side.
[0030] [3. Configuration of protective case] The protective case 300 is detachably attached to the device case 1. FIG. 9 shows a front view of the protective case 300. FIG. 10 shows a rear view of the protective case 300. FIG. 11 shows a right side view of the protective case 300. FIG. 12 shows a top view of the protective case 300. FIG. 13 shows a bottom view of the protective case 300. FIG. 14 shows a cross-sectional view taken along line XIV-XIV shown in FIG. 9. FIG. 15 shows a cross-sectional view taken along line XV-XV shown in FIG. 9.
[0031] As shown in FIGS. 9 to 11, protective case 300 includes a first case member 310 and a second case member 320. As shown in FIG.
[0032] (3-1. First case member) The first case member 310 is made of an elastic material, such as urethane resin or rubber, having a first dielectric constant.
[0033] The first case member 310 has a rear portion 311, a side portion 312, a top portion 313, a bottom portion 314, and a second opening 315. The rear portion 311 covers the rear side of the device case 1, i.e., the lower surface of the lower case 3. The side portion 312 covers the side surface of the device case 1. The top portion 313 covers the top surface side of the device case 1. The bottom portion 314 covers the bottom surface side of the device case 1. The second opening 315 is an opening for attaching the protective case 300 to the device case 1.
[0034] 9 to 11, the rear surface portion 311 has a first protrusion 311a that covers the battery lid 8. The first protrusion 311a protrudes downward in accordance with the shape of the battery lid 8.
[0035] As shown in FIG. 9 and FIG. 14, the rear part 311 has a plurality of first holes 311b and a plurality of second holes 311c in the central part in the longitudinal direction of the protective case 300. The first holes 311b have a substantially circular opening shape and are provided in the first protruding part 311a. The second holes 311c have a slit shape and are provided on the edge of the first protruding part 311a. The first holes 311b and the second holes 311c penetrate the first case member 310 from the first surface 311h to the second surface 311i. The first surface 311h is a surface of the rear part 311 facing the device case 1 and covering the rear side of the device case 1. The second surface 311i is a surface opposite to the first surface 311h. The first holes 311b and the second holes 311c function as holes for gas escape during molding of the first case member 310. Furthermore, the first hole 311b and the second hole 311c are used to fix an insert part within the mold for the first case member 310 when the first case member 310 is molded.
[0036] 9 and 10, the rear surface 311 has a first opening 311d through which the camera unit 71 and the LED 72 provided on the lower surface of the lower case 3 are exposed to the outside. The shape of the opening of the first opening 311d corresponds to the shapes of the camera unit 71 and the LED 72.
[0037] 9 and 10, the rear surface 311 has an opening 311e through which the label 13 provided on the lower surface of the lower case 3 is exposed to the outside. The shape of the opening 311e corresponds to the shape of the label 13.
[0038] 9 and 10, rear surface portion 311 has opening 311f through which speaker 15 provided on the lower surface of lower case 3 is exposed to the outside. The shape of opening 311f corresponds to the shape of speaker 15.
[0039] 9 and 10, the rear surface portion 311 has an opening 311g through which the belt attachment portion 16 provided on the lower surface of the lower case 3 is exposed to the outside. The shape of the opening 311g corresponds to the shape of the belt attachment portion 16.
[0040] 9 and 10, the rear surface portion 311 has a plurality of other openings. For example, the rear surface portion 311 has openings at positions corresponding to the wireless communication antennas 12A and 12B. This makes it possible to prevent the protective case 300 from deteriorating the radio wave performance of the wireless communication antennas 12A and 12B.
[0041] 9, 10, and 15, the rear surface portion 311 and the bottom surface portion 314 have a third opening 317 at the rear portion of the protective case 300. The third opening 317 is disposed at a position corresponding to the wireless communication antenna 12 in the thickness direction (up-down direction) of the device case 1 when the protective case 300 is attached to the device case 1. This makes it possible to prevent the wireless communication antenna 12 from being significantly degraded in radio wave performance due to the wireless communication antenna 12 being covered by the first case member 310 made of urethane resin or the like.
[0042] In addition, in protective case 300, first case member 310 arranged between third openings 317 and partitioning third openings 317 may be omitted. In this case, degradation of the radio wave performance of wireless communication antenna 12 can be further suppressed.
[0043] As shown in Fig. 9 to Fig. 11, the side surface portion 312, the top surface portion 313, and the bottom surface portion 314 have thick portions 316 respectively provided at the four corners of the protective case 300. The thick portions 316 are formed on two surfaces intersecting at each corner of the protective case 300, extending the same length on both sides from the apex angle, and are thicker than other portions of the first case member 310. As a result, when the protective case 300 housing the device case 1 is dropped and the vicinity of the corner hits the floor surface, the thick portions 316 absorb the impact, and damage to the mobile terminal 100 can be prevented.
[0044] 11, the side surface portion 312 has an opening 312a through which the power button 5b provided on the right side surface of the device case 1 is exposed to the outside. The shape of the opening 312a corresponds to the shape of the power button 5b.
[0045] 11, the side surface portion 312 has an opening 312b through which the trigger key 5c provided on the right side surface of the device case 1 is exposed to the outside. The shape of the opening 312b corresponds to the shape of the trigger key 5c.
[0046] 11, the side surface portion 312 has an opening 312c through which the IF unit 14 provided on the right side surface of the device case 1 is exposed to the outside. The shape of the opening 312c corresponds to the shape of the IF unit 14.
[0047] The dashed line shown in Fig. 14 indicates the upper surface of the device case 1 in a state in which the protective case 300 is attached to the device case 1. As shown in Fig. 14, the top surface portion 313 and the bottom surface portion 314 protrude upward from the upper surface of the device case 1 in a state in which the protective case 300 is attached to the device case 1. Similarly, the side surface portion 312 protrudes upward from the upper surface of the device case 1 in a state in which the protective case 300 is attached to the device case 1. In other words, the side surface portion 312, the top surface portion 313, and the bottom surface portion 314 are configured so that when the upper surface side of the device case 1 is in contact with the floor surface, the side surface portion 312, the top surface portion 313, and the bottom surface portion 314 abut on the floor surface. In other words, the side surface 312, the top surface 313, and the bottom surface 314 of the first case member 310 are arranged at positions where they can come into contact with the floor surface (flat surface) when the protective case 300 attached to the mobile terminal 100 is dropped onto the floor surface (flat surface). The side surface 312, the top surface 313, and the bottom surface 314 form the edge of the second opening 315. That is, the edge of the second opening 315 protrudes from the upper surface (front surface) of the mobile terminal 100 attached to the protective case 300. This makes it possible to prevent the input display unit 4 from coming into contact with the floor surface when the protective case 300 attached to the mobile terminal 100 is dropped onto the floor surface (flat surface) and the upper surface side of the device case 1 is close to the floor surface.
[0048] 12, the top surface 313 has an opening 313a through which the scanner unit 6 provided on the top surface of the device case 1 faces the outside. The shape of the opening of the opening 313a corresponds to the shape of the scanner unit 6.
[0049] 13, the bottom surface portion 314 has an opening 314a through which the connection electrode portion 11 provided on the bottom surface of the device case 1 is exposed to the outside. The shape of the opening of the opening 314a corresponds to the shape of the connection electrode portion 11.
[0050] As described above, in the case where the protective case 300 attached to the mobile terminal 100 is dropped to the floor, the first case member 310 made of an elastic material such as urethane resin is disposed at a portion of the protective case 300 that may come into contact with the device case 1. This makes it possible to prevent the device case 1 from being scratched when the protective case 300 comes into contact with the device case 1.
[0051] (3-2. Second case member) The second case member 320 is made of a hard resin material that is more rigid than the first case member 310 and has a second dielectric constant closer to a predetermined dielectric constant (the dielectric constant of the device case 1) than the first dielectric constant, or a material having a predetermined dielectric constant. The second dielectric constant is within a predetermined range from the predetermined dielectric constant (the dielectric constant of the device case 1).
[0052] As shown in FIGS. 10 and 11, the second case member 320 has a band-shaped region 321, a side portion 322, and a rear portion 323.
[0053] The strip-shaped region 321 is disposed on the second surface 311i of the first case member 310, as shown in Figs. 14 and 15. The strip-shaped region 321 is disposed in the center of the device case 1 in the longitudinal direction, and extends in the lateral direction of the device case 1, as shown in Figs. 10 and 11. Specifically, the strip-shaped region 321 covers approximately two-thirds of the area from a position located forward of the front end 311aa of the first protrusion 311a to the rear end 311ab of the first protrusion 311a. That is, the strip-shaped region 321 is disposed in a position corresponding to the connection terminal 201 provided at the front end 200a of the battery pack 200 in the thickness direction (vertical direction) of the mobile terminal 100. Specifically, as shown in Figs. 14 and 15, an upper end 321a is provided on the front side of the strip-shaped region 321 (the side of one end 1a in the longitudinal direction of the device case 1). The upper end portion 321a is shaped to cover the connection terminal 201, and is configured such that the end of the upper end portion 321a is positioned closer to the longitudinal end portion 1a of the device case 1 than the connection terminal 201 in the longitudinal direction of the device case 1.
[0054] 10 and 11, the side surface portion 322 is located at a central portion in the longitudinal direction of the side surface of the device case 1, and at a portion extending from the central portion toward the other end portion 300b of the protective case 300. The side surface portion 322 is disposed on the opposite side to the side covering the side surface of the device case 1 in the first case member 310. As shown in Fig. 11, the side surface portion 322 has an opening 322b through which the trigger key 5c provided on the right side surface of the device case 1 is exposed to the outside. The shape of the opening 322b approximately matches the shape of the opening 312b.
[0055] As shown in Fig. 10 and Fig. 11, the rear part 323 is provided from the rear end 311ab of the first protrusion 311a to the other end 300b of the protective case 300. Also, as shown in Fig. 9, the rear part 323 covers a part of the third opening 317. That is, in a state where the protective case 300 is attached to the device case 1, the rear part 323 is disposed at a position corresponding to the wireless communication antenna 12 in the thickness direction of the device case 1. In the above configuration, the second case member 320 is formed from a material having a second dielectric constant closer to a predetermined dielectric constant (the dielectric constant of the device case 1) than the first dielectric constant, or a predetermined dielectric constant, and therefore does not significantly degrade the radio wave performance of the wireless communication antenna 12.
[0056] 10, the rear portion 323 has an opening 323a and a second protrusion 323b. The opening 323a is configured so that the other end of the hand belt attached to the belt attachment portion 16 can be inserted therethrough. The second protrusion 323b fits into a hole, a recess, or the like on the charging base when the portable terminal 100 with the protective case 300 attached thereto is placed on the charging base. This makes it possible to fix the position of the portable terminal 100 relative to the charging base. In other words, the second protrusion 323b functions as a positioning portion.
[0057] As described above, by providing the protective case 300 with the second case member 320, deformation due to elongation of the first case member 310 can be suppressed more than when the protective case 300 is configured only with the first case member 310. This improves the durability of the protective case 300.
[0058] Further, the second case member 320 is not arranged in the front part of the protective case 300, and the protective case 300 is composed of only the first case member 310. The front part of the protective case 300 is the first end side (one end 300a side) in the longitudinal direction of the mobile terminal 100 where the camera unit 71 (imaging unit) is arranged. Therefore, when attaching the protective case 300 to the device case 1, first, the rear part where the second case member 320 is arranged and is difficult to deform is attached to the device case 1. Next, the front part where only the first case member 310 is easily deformed is attached to the device case 1. On the other hand, when removing the protective case 300 from the device case 1, first, the front part where only the first case member 310 is easily deformed is removed. Next, the rear part where the second case member 320 is arranged and is difficult to deform is removed from the device case 1. Since the front portion of the protective case 300 is composed only of the first case member 310, it is easier to attach and remove the protective case 300 from the device case 1 than when the second case member 320, which is a member formed from a material harder than an elastic material, covers the entire back and side surfaces of the device case 1.
[0059] [4. Effects] As described above, the protective case 300 of the present embodiment is a protective case 300 that is detachably attached to the mobile terminal 100, and includes a first case member 310 formed of an elastic material and covering the back side of the mobile terminal 100, and a second case member 320 formed of a material having higher rigidity than the first case member 310. The second case member 320 is disposed in the center portion in the longitudinal direction of the mobile terminal 100 and includes a strip-shaped region 321 extending in the lateral direction of the mobile terminal 100, and the strip-shaped region 321 is disposed on the opposite side of the first case member 310 from the side covering the back side of the mobile terminal 100. This makes it easier to attach and detach the protective case 300 to and from the mobile terminal 100 than when a member formed of a material harder than the elastic material covers the entire back and side surfaces of the mobile terminal 100. In addition, deformation due to stretching of the elastic member can be suppressed compared to when the protective case 300 is composed of only an elastic member. This improves the durability of the protective case 300.
[0060] Moreover, in the protective case 300 of this embodiment, the first case member 310 is configured to cover the side of the mobile terminal 100 when the protective case 300 is attached to the mobile terminal 100, and the second case member 320 is disposed in the center part of the longitudinal direction of the mobile terminal 100 on the opposite side to the side of the first case member 310 that covers the side of the mobile terminal 100. This makes it possible to suppress deformation due to stretching of the elastic member even on the side of the mobile terminal 100, thereby improving the durability of the protective case 300.
[0061] In protective case 300 of this embodiment, second case member 320 is disposed at a location in the thickness direction of mobile terminal 100 that corresponds to connection terminal 201 provided on secondary battery (battery pack 200) that mobile terminal 100 has.
[0062] In addition, in the protective case 300 of this embodiment, the first case member 310 is disposed at a position where it can come into contact with a flat surface when the protective case 300 attached to the mobile terminal 100 is dropped onto the flat surface. This makes it possible to prevent the input display unit 4 from coming into contact with the floor surface when the top side of the mobile terminal 100 is close to the floor surface. In addition, when the protective case 300 attached to the mobile terminal 100 is dropped and the vicinity of the corner hits the floor surface, the impact is absorbed by the thick portion 316, and damage to the mobile terminal 100 can be prevented.
[0063] In addition, in the protective case 300 of this embodiment, the first case member 310 is disposed at a position where the mobile terminal 100 and the protective case 300 may come into contact when the protective case 300 attached to the mobile terminal 100 is dropped. This makes it possible to prevent the device case 1 of the mobile terminal 100 from being scratched when the protective case 300 comes into contact with the device case 1.
[0064] In addition, in the protective case 300 of this embodiment, only the first case member 310 is arranged on the first end side (one end 1a side) in the longitudinal direction of the mobile terminal 100 where the imaging unit (camera unit 71) is arranged, and the first case member 310 is formed with a first opening 311d having a shape corresponding to the shape of the imaging unit. This makes it easy to attach and detach the protective case 300 to the mobile terminal 100. In addition, when the protective case 300 is attached to the mobile terminal 100, the subject can be imaged by the camera unit 71.
[0065] Furthermore, in protective case 300 of this embodiment, first case member 310 is provided with second opening 315 for mounting protective case 300 on mobile terminal 100, and an edge of second opening 315 protrudes beyond the front surface (top surface) of mobile terminal 100 mounted in protective case 300. This makes it possible to prevent input display unit 4 from abutting against the floor surface when the top surface side of mobile terminal 100 is close to the floor surface.
[0066] In addition, in protective case 300 of this embodiment, second case member 320 is disposed at a location extending from the center portion in the longitudinal direction of mobile terminal 100 toward the second end side (the other end 1b side). This makes it possible to further suppress deformation due to stretching of the elastic member, thereby improving the durability of protective case 300.
[0067] The mobile terminal unit 400 of this embodiment includes a protective case 300 and a mobile terminal 100 to which the protective case 300 is detachably attached, and the protective case 300 includes a first case member 310 formed of an elastic material and covering the back side of the mobile terminal 100, and a second case member 320 formed of a material having higher rigidity than the first case member 310, and the second case member 320 is disposed in the center portion in the longitudinal direction of the mobile terminal 100 and includes a strip-shaped region 321 extending in the lateral direction of the mobile terminal 100, and the strip-shaped region 321 is disposed on the opposite side of the first case member 310 from the side covering the back side of the mobile terminal 100. This makes it easier to attach and detach the protective case 300 to and from the mobile terminal 100 than when a member formed of a material harder than the elastic material covers the entire back and side surfaces of the mobile terminal 100. Furthermore, deformation due to stretching of the elastic member can be suppressed compared to when protective case 300 is made of only elastic members, thereby improving the durability of protective case 300.
[0068] The shape, number, and positions of the first hole 311b and the second hole 311c are not limited to those shown in the above embodiment. If it is not necessary to form the first hole 311b and the second hole 311c when molding the first case member 310, the first hole 311b and the second hole 311c may be omitted from the protective case 300.
