Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery holder loading / unloading device. 2. Description of the Related Art In a thin electronic device, a battery mounting structure in which a battery can be attached to and detached from a device body has conventionally been provided with a battery take-out / intake port of a battery housing portion on the back surface of the device body.
The battery mounted through the take-out and intake port is held by screwing a plate-shaped battery cover to the device body. However, in the conventional mounting structure using such screws, the battery cannot be replaced or checked unless a tool such as a driver is provided,
It was very inconvenient to carry and go out. In addition, when tightening the screw, the screw head may become deformed, the boss part of the device body may be damaged, or the screw hole may become worn, and screw tightening may not be possible. In addition, there is a drawback that the screw head may be caught when it is stored in a pocket or the like. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a battery holder loading / unloading device capable of loading / unloading a battery in / from a battery housing without using a screw. It is in. The present invention comprises a battery holder accommodating a battery, and a device main body having a battery accommodating portion into which the battery holder can be attached / detached. In the battery storage portion and the battery holder, when the battery holder is stored in the battery storage portion, a storage portion side engagement portion and a holder side engagement portion that elastically engage each other are formed, The device body is formed with a through hole into which a release pin for pressing the holder-side engaging portion in a direction in which the holder-side engaging portion is disengaged from the housing-side engaging portion can be inserted. The storage portion side engaging portion is, for example, a locking concave portion, and the holder side engaging portion is, for example, a locking hook. Also, the battery holder supports the outer periphery of the battery,
For example, it is formed in a frame shape. Since the present invention has such a structure, when the battery holder is housed in the battery housing portion, the housing portion side engaging portion formed in the battery housing portion and the battery holder are formed. The holder-side engaging portions formed are elastically engaged with each other, and therefore, the detachment of the battery holder from the inside of the battery housing can be prevented in advance, while the inside of the through hole formed in the device body is prevented. When the release pin is inserted and the release pin is further pressed, the holder side engaging portion is disengaged from the storage portion side engaging portion, so that the battery holder can be easily and quickly taken out from the battery storage portion. Can be done.

(At 5 mm) is about 0.48 mm, and the total thickness of these is about 0.8 mm, resulting in a very thin calculator. Further, since the above computer uses the paper-shaped thin battery 12 as the primary battery, it is possible to mount a calculation function having a memory function, a clock function and the like, and a multifunctional card-type small electronic calculator. Can be obtained. In the above-described embodiment, the thin battery 12 is used.
The battery holder 13 is supported by the frame-shaped battery holder 13, but the present invention is not limited to this, and may be the one as shown in FIG. 5, for example. That is, the battery holder 20 shown in FIG. 5 is one in which the bottom plate 20b is provided below the frame-shaped member 20a that surrounds the three directions, except for the portion located on the inner side of the battery housing portion 9b. An insulating film 20c is formed on the upper surface of 20b and the inner wall surface of the frame-shaped member 20a, and a conductive connecting member 20d is formed on the insulating film 20c.
Are formed. This connecting member 20d is the battery holder 2
When the positive electrode sheet 12f of the thin battery 12 housed in 0 contacts and the battery holder 20 is mounted in the battery housing 9b, it contacts the lower surface side electrode terminal 7e of the flexible substrate 7, thereby The thin battery 12 and the flexible substrate 7 are electrically connected. In this case, the connecting member 20 is connected to the electrode terminal 7e of the flexible substrate 7.
A pressing portion 20e similar to the pressing portion 17 of the above-described embodiment is formed on the bottom plate 20b at the position where d contacts. A locking hook 20f similar to that of the above-described embodiment is also formed on one side of the frame-shaped member 20a. According to such a battery holder 20, in addition to the same operational effects as the above-mentioned embodiment, the bottom plate 20 in particular is provided.
Since the connecting member 20d is formed on the b via the insulating film 20c, the lower connecting member 18 and the pressing portion 17 of the reinforcing plate 15 are formed.
Is unnecessary, and the paper-shaped thin battery 12 can be stored and electrically connected reliably and satisfactorily. In addition, in the above-mentioned embodiment, the battery holders 13 and 20 are provided with the locking hooks 13a and 20f, and the battery housing portion 9b is provided with the locking recess 9d.
