A battery holder 1 having a pair of convex portions 1c provided in a case body of a portable electronic device, a lead-out portion 1b and a flange portion 1d provided on an upper surface, and a pair of convex portions 1a provided on a side surface, and the battery holder. An impact force to be received at the time of dropping is provided so as to surround the tool and provided with a pair of step portions 2b engaged with the collar portion 1d and a case body 2 having a concave portion 2a fitted to the convex portion 1a provided on the side surface The battery case was pushed open to prevent it from popping out.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a battery holding portion of a portable thin electronic device, which has a battery that can be removed by a battery holder inside a device body, and is particularly suitable for a card-type pager.

[0002]

[Prior Art]

 2 and 3 show a conventional technique. FIG. 2 is a partial cross-sectional view showing the periphery of the battery holder 6. In this case, the side surface of the battery holder 6 is provided with a concave portion 6a. 6b is a drawer part for drawing out the battery holder 6. The case body 5 has a pair of four leaf springs, and a convex portion 4a is provided at each end of the leaf spring 4. The recess 4a and the recess 1d were fitted to each other so that the battery holder 6 was supported by the force of the leaf spring 4.

FIG. 3A is a front view of the electronic device, and FIG. 3B is a side view of the electronic device. In FIG. 3A, 6 is a battery holder, and 5 is a case body.

[0004]

[Problems to be solved by the device]

 In the conventional example, when the battery holder 6 is directed downward and the electronic device body is dropped, a large force is generated in the battery having a relatively large weight, so that the battery holder 1 may be detached due to a drop impact. It was In the electronic device, the removal of the battery is a serious drawback because it erases the information content that has already been stored.

[0005]

[Means for Solving the Problems]

 The beam on the side of the battery holder extending from the lead-out portion is provided with a protrusion in the vicinity of the holder drawer, and the beam serving as the inner surface of the protrusion on the side of the battery holder has a support for supporting the battery. Then, an accommodating portion for accommodating the battery holder in the main body of the apparatus, and a recess on the side surface of the accommodating portion for fitting with a protrusion on the side surface of the battery holder.

[0006]

[Action]

 When dropped, a relatively heavy battery exerts a strong impact force in the falling direction on the battery holder. If you try to restrain the battery from the front diagonally in the dropping direction, the battery has a circular shape, so a force is generated to push the beam on the side surface of the battery holder. This pushing force spreads the battery holder so that the battery holder fitting part is fixed, so that the battery holder does not come off easily.

【Example】

 FIG. 1 is a sectional view of an embodiment of the present invention. Reference numeral 1 denotes a battery holder, which surrounds and stores the disk-shaped battery 3 by means of side walls, and the inner surface of the side wall is provided with a pair of battery supporting members provided on the inner side of the drawer-like portion and the side surface on the inlet side of the drawer-like portion. A battery supporting portion including the convex portion 1c is formed. A pair of convex portions 1a is provided at the base of the convex portion 1c, a drawer portion 1b is provided on the inlet side of the drawer-like portion, and a collar portion 1d is provided at both ends of its extension. Reference numeral 2 denotes a case body of the electronic device, which has a guide wall surrounding the battery holder 1 and a step portion 2b which engages with the collar portion 1d, and a convex portion 1a of the battery holder 1 on the side surface. A concave portion 2a that engages is provided.

When the battery 3 is attached or detached, by pulling with a finger on the pull-out portion 1b, the convex portion 1a is elastically deformed from the concave portion 2a, and the battery holder 1 is pulled out from the case body 2 and attached. At this time, the battery holder 1 containing the battery 3 is pushed into the case body 2 to spread the concave portion 2a of the case body 2 to fit the convex portion 1a of the battery holder 1. The battery holder 1 and the case body are made of an elastic body such as plastic, and the battery holder 1 has an interrupt groove (not shown) formed in the thickness direction near the pair of battery support portions 1c. Even when an external force such as an impact force is applied, the external force can be absorbed and the battery 3 can be prevented from popping out. It should be noted that the same effect can be obtained even if the convex portion and the concave portion provided on the engaging portion of the battery holder 1 and the case body 2 are provided on either side.

[0009]

EFFECTS OF THE INVENTION It is useful that the battery holder 1 is firmly held at least when the battery holder 1 is directed downward, and falls on the floor. This can be done by putting a finger on the drawer and applying a small vertical force. When the battery holder 1 is pushed in the opposite direction, the battery holder 1 is pushed in, so there is no danger of it coming off. As described above, it is possible to obtain an electronic device having a simple structure, a small number of parts, and a sufficient holding power of the battery holder 1. Also, when the combination of the concave portion and the convex portion is reversed, the same function is obtained.
