The case 100 includes a hollow case body 10 having a flat box shape and a battery holder (holder) 20 detachably housed in the case body 10 . The case body 10 is composed of an upper case body 10a arranged on the front side and a lower case body 10b arranged on the back side, and these members are assembled. As shown in FIGS. 1B and 2B, four operation buttons 11 for moving the cursor are arranged on the top plate portion 101a of the upper case main body 10a. By selecting and operating one of the four operation buttons 11, the cursor can be moved in a desired direction. As shown in FIGS. 1A and 2A, a label 12 indicating, for example, how to attach and detach the battery holder 20 is arranged on the bottom plate portion 101b of the lower case main body 10b. An opening 13 into which the battery holder 20 is inserted is provided at the rear of the case body 10 .

The battery holder 20 is a member that detachably holds the button battery 30 . The battery holder 20 is a flat member and has a battery mounting portion 21 that detachably holds a disc-shaped button battery 30 having a horizontal diameter φW and a Z-direction thickness H. The battery holder 20 is inserted through the opening 13 of the case body 10 with the button battery 30 attached to the battery attachment portion 21 . As a result, the button battery 30 and the circuit board 50 are electrically connected, and the remote controller 1 becomes usable. Also, the battery holder 20 has a hook portion 22 provided behind the battery mounting portion 21 . When removing the battery holder 20 from the case main body 10, the battery holder 20 can be removed by hooking a fingernail or the like on the hook portion 22 and pulling the battery holder 20 rearward.

As shown in FIG. 2, the battery holder 20 is cantilevered behind the battery mounting portion 21 and has an elongated plate-shaped arm portion 23 along the Y direction. The arm portion 23 is arranged on the negative side in the X direction with respect to the hook portion 22 . Note that the battery holder 20 is formed by integrally forming a battery mounting portion 21, a hook portion 22, and an arm portion 23. As shown in FIG. The arm portion 23 has an elastic portion 25 and an operating portion 24 . The operating portion 24 is provided on the free end side of the arm portion 23, that is, on the positive side in the Y direction. The operation portion 24 is a portion of the arm portion 23 with increased width and thickness, and can be hooked with a fingernail or the like.

The elastic portion 25 is located on the Y-direction negative side of the operation portion 24 . The elastic portion 25 has an elastic portion 25 that is elastically deformable by flexing in the X direction and the Z direction.

Next, a state in which the battery holder 20 is housed in the case main body 10 together with the button battery 30 (hereinafter referred to as "housed state") will be described. FIG. 3 is a sectional view taken along line AA of FIG. 1(a). FIG. 4 is a cross-sectional view taken along the line BB of FIG. 1(a). 3 and 4, the circuit board 50 is omitted. 5 is a perspective view showing a state in which the remote controller shown in FIG. 1 is in the process of removing the battery holder. FIG. 6 is a cross-sectional view taken along line CC of FIG. 5. FIG. The case 100 has a first engagement mechanism 40 (see FIG. 4) and a second engagement mechanism 60 (see FIG. 6). The first engagement mechanism 40 is a portion that engages the case body 10 and the battery holder 20 in the stored state. Engagement by the first engagement mechanism 40 is performed at the first position, which is the insertion limit position where the battery holder 20 is inserted most deeply into the case body 10 . Also, at this first position, the button battery 30 and the circuit board 50 are electrically connected. As a result, remote control by the remote controller 1 becomes possible. The second engagement mechanism 60 is a portion that engages the case body 10 and the battery holder 20 at a different position from the first engagement mechanism 40 in the housed state. Engagement by the second engagement mechanism 60 is performed at a second position where the battery holder 20 is pulled out slightly from the first position while maintaining the stored state. At this second position, the electrical connection between the button battery 30 and the circuit board 50 is released.

As shown in FIG. 4 , the first engaging mechanism 40 has a first engaging portion 26 a formed on the arm portion 23 and a first engaged portion 16 a formed on the case body 10 . The first engaging portion 26a is formed in the middle of the arm portion 23 in the longitudinal direction (the boundary portion between the elastic portion 25 and the operation portion 24 in this embodiment). The first engaging portion 26a protrudes toward the negative side in the X direction, and has a wedge shape whose protrusion height gradually increases toward the positive side in the Y direction. The first engaged portion 16a is formed at the edge of the opening 13 of the case body 10, and can be engaged with the first engaging portion 26a from the Y-direction positive side. Thereby, the stored state of the battery holder 20 at the first position can be maintained. Further, the engagement in the first engagement mechanism 40, that is, the engagement between the first engaging portion 26a and the first engaged portion 16a can be released. This release operation (hereinafter referred to as “first release operation”) can be performed by moving the operating portion 24 in the first direction α1 (positive side in the X direction), which is the flattening direction of the case body 10 .

As shown in FIG. 3, the arm portion 23 has a first contact portion 27a and a second contact portion 27b formed on the top and bottom of the drawing. The first contact portion 27a is arranged on the Y-direction negative side of the operation portion 24, and the second contact portion 27b is arranged on the Z-direction negative side of the operation portion 24. As shown in FIG. Further, the case body 10 has a first abutted portion 17 a and a second abutted portion 17 b formed at the edge of the opening 13 of the case body 10 . Then, while the retracted state is maintained by the engagement of the first engagement mechanism 40, the first contact portion 27a contacts the first contacted portion 17a from the negative side in the Z direction, and the second contact portion 27a The portion 27b contacts the second contacted portion 17b from the positive side in the Z direction. As a result, when the operating portion 24 is operated in the first direction α1, the first contact portion 27a slides on the first contacted portion 17, and the second contact portion 27b moves toward the second contacted portion 17b. to slide. This sliding guides the operating portion 24, so that the operating portion 24 can be stably operated in the first direction α1.

As shown in FIG. 6 , the second engaging mechanism 60 has a second engaging portion 26 b formed on the arm portion 23 and a second engaged portion 16 b formed on the case body 10 . The second engaging portion 26b is formed at a different position from the first engaging portion 26a in the middle of the arm portion 23 in the longitudinal direction (the boundary portion between the elastic portion 25 and the operating portion 24 in this embodiment). The second engaging portion 26b protrudes in a direction different from that of the first engaging portion 26a (the negative side in the Z direction in this embodiment). Similarly to the first engaged portion 16a, the second engaging portion 26b has a wedge shape in which the protrusion height gradually increases toward the positive side in the Y direction. The second engaged portion 16b is formed at a position different from the first engaged portion 16a on the edge of the opening 13 of the case body 10, and the second engaging portion 26b engages from the positive side in the Y direction. do. Thereby, the stored state of the battery holder 20 at the second position can be maintained (see FIG. 5). Further, the engagement in the second engagement mechanism 60, that is, the engagement between the second engaging portion 26b and the second engaged portion 16b can be released. This release operation (hereinafter referred to as "second release operation") is made possible by moving the operation unit 24 in a second direction α2 (positive side in the Z direction) that intersects with the first direction α1. In the present embodiment, the second direction α2 is the thickness direction of the case body 10, that is, the direction orthogonal to the first direction α1, but is not limited to this. For example, depending on the shape of the arm portion 23, the second direction α2 may be a direction that is inclined with respect to the first direction α1. Further, when performing the second release operation, the first contact portion 27a is separated from the first contact portion 17 by the amount that the battery holder 20 has moved from the first position to the second position. As a result, the operating portion 24 can be sufficiently moved in the second direction α2, and the engagement at the second engagement mechanism 60 is released. Then, the battery holder 20 can be pulled out in this state and separated from the case main body 10 . As a result, for example, the button battery 30 held in the battery holder 20 can be replaced.

As described above, in the engaged state by the first engagement mechanism 40, the first contact portion 27a contacts the first contacted portion 17a from the Z direction negative side, and the second contact portion 27b contacts the Z direction negative side. It abuts on the second abutted portion 17b from the positive side. This restricts the operation of the operation unit 24 in the second direction α2, and allows the user to reliably operate the operation unit 24 in the first direction α1. Thus, the first contact portion 27a and the first contacted portion 17a, and the second contact portion 27b and the second contacted portion 17b are the first contact portion of the operation portion 24 when the first release operation is performed. It also functions as a direction restricting portion that restricts operations in two directions α2.

As shown in FIG. 2B, the position of the first engaging portion 26a and the position of the second engaging portion 26b in the longitudinal direction of the arm portion 23 are the same. In addition, the second engaged portion 16b is located behind the first engaged portion 16a (on the operation portion 24 side). Due to such a positional relationship, case 100 can take the following two states depending on the position of battery holder 20 with respect to case body 10 . The first state is a state in which the first engagement mechanism 40 is engaged and the second engagement mechanism 60 is disengaged (see FIG. 4). The second state is a state in which the first engagement mechanism 40 is disengaged and the second engagement mechanism 60 is engaged (see FIG. 6). Thereby, the first release operation and the second release operation can be performed at different timings. In this embodiment, the first release operation is performed first, and then the second release operation is performed.

By the way, for example, if the remote controller 1 is accidentally dropped on the floor, the remote controller 1 collides with the floor. Depending on the direction of impact received by the remote controller 1, an impact load acts on the remote controller 1 in the same direction (first direction α1) as the first release operation for releasing the engagement of the first engagement mechanism 40. There is a risk. When this impact load acts, the first engagement mechanism 40 disengages, the battery holder 20 moves rearward from the first position, and is about to separate from the case body 10 . However, before the battery holder 20 is detached from the case body 10, the second engagement mechanism 60 engages and can stay at the second position. As a result, the button battery 30 can be kept in the stored state, and thus the button battery 30 can be prevented from being detached from the battery holder 20 .

When the remote controller 1 is dropped on the floor, the remote controller 1 collides with the floor, but the number of collisions is usually one. Although the engagement at the first engagement mechanism 40 can be released only by this one collision, the second release operation for releasing the engagement at the second engagement mechanism 60 is performed in the same direction (second direction). The impact load of α2) cannot occur. As a result, the disengagement of the second engagement mechanism 60 does not occur. Further, as described above, in the battery holder 20 at the first position, the first contact portion 27a contacts the first contacted portion 17a from the negative side in the Z direction, and the second contact portion 27b contacts the negative side in the Z direction. It abuts on the second abutted portion 17b from the positive side. As a result, deformation of the arm portion 23 in the Z direction is restricted, and vibration of the remote controller 1 at the time of drop impact is suppressed. Depending on the extent of this restraint, the engagement by the first engagement mechanism 40 can be maintained to prevent unintended rearward movement of the battery holder 20 from the first position. Further, the case 100 is composed of two members, the case main body 10 and the battery holder 20, and a member separate from these members is provided to engage the first engagement mechanism 40 and the second engagement mechanism with the member. 60. As a result, the number of parts of the case 100 can be reduced, and the case 100 can have a simple configuration.

As described above, the remote controller 1 can prevent the button battery 30 from being unintentionally removed from the case 100 with a simple configuration.

<Second embodiment>
A second embodiment will be described below with reference to FIG. FIG. 7 is a cross-sectional view showing a state in the middle of removing the battery holder when the electronic device according to the second embodiment of the present invention is applied to a remote controller. FIG. 7A is a cross-sectional view showing a state in which the battery holder 20 is pulled out until the second engaging portion 26b and the second engaged portion 16b are engaged. FIG. 7(b) is a cross-sectional view showing a state in which the operating portion 24 is moved in the second direction α2 from the state shown in FIG. 7(a). Note that the circuit board 50 is omitted in FIGS. 7(a) and 7(b). This embodiment is the same as the first embodiment except that the case 100 has an operation limit regulation section (operation regulation section) 70 .

As shown in FIGS. 7A and 7B, the case 100 has an operation limit regulation section 70 that regulates the operation limit of the operation section 24 when the second release operation is performed. The operation limit restricting portion 70 is composed of a slope portion 28 formed on the arm portion 23 and a slope portion 18 formed on the case body 10 . The slope portion 28 is formed between the elastic portion 25 and the first contact portion 27 a and is a portion that is inclined with respect to the Y direction, that is, the longitudinal direction of the arm portion 23 . The sloped portion 18 is formed at the edge of the opening 13 of the case body 10 and is a portion that is inclined in the same direction as the sloped portion 28 . In addition, the slope portion 18 is positioned on the Y-direction positive side with respect to the first contacted portion 17a.

In the state shown in FIG. 7A, the second engaging portion 26b and the second engaged portion 16b are engaged. Thereby, the battery holder 20 is stopped at the second position. Moreover, at this time, the inclined surface portion 28 of the arm portion 23 and the inclined surface portion 18 of the case body 10 are separated from each other.

Then, from the state shown in FIG. 7(a), the operating portion 24 is operated to move in the second direction α2 and the second release operation is performed, resulting in the state shown in FIG. 7(b). In the state shown in FIG. 7B, the second engaging portion 26b is separated from the second engaged portion 16b and the engagement with the second engaged portion 16b is released. This allows the battery holder 20 to move rearward. Also, at this time, the sloped portion 28 of the arm portion 23 and the sloped portion 18 of the case body 10 come into contact with each other. As a result, the user can recognize that the operation limit of the operation unit 24 is restricted and the battery holder 20 can be moved by the second release operation.

7B, the slope portion 28 slides along the inclination direction of the slope portion 18 by operating the operation portion 24 to move in the second direction α2. As a result, the battery holder 20 can be moved further rearward than in the state shown in FIG. This makes it easier to pull out the battery holder 20 than when a fingernail or the like is hooked on the hook 22 . Further, the operation limit restricting portion 70 composed of the slope portion 28 and the slope portion 18 assists in moving the battery holder 20 backward in a state in which the second engagement mechanism 60 is disengaged. It also functions as a part. As a result, it is possible to omit providing an auxiliary section in addition to the operation limit restricting section 70 , thereby contributing to the simplification of the configuration of the case 100 .

Although preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes are possible within the scope of the gist thereof. In each embodiment, the remote controller 1 is used as an applicable electronic device, but the present invention is not limited to this, and may be, for example, an optical device such as a camera, or a game device such as a mobile game. In addition, although the battery held by the battery holder 20 is the button battery 30 in each embodiment, it is not limited to this, and may be, for example, a columnar dry battery such as a single dry battery. In each embodiment, an electronic device that holds a button battery has been described, but the present invention is also applicable to electronic devices that hold small electronic components such as microSD cards and SIM cards.
