In each of the drawings, the same reference numerals as those in the above-described conventional examples denote the same or corresponding parts.

[0012] Card type electronic device 1 in the present embodiment
The respective configurations of the battery holder 6 and the battery holder 6 that can be pushed and engaged in the mounting space 3 of the card-type electronic device 1 and that can be released and pulled out are fitted in the locking square holes 5 as compared with the above-described conventional configuration. The configuration is the same except that the form of the locking projection 12 that is engaged and held together is different.

Here, the locking projection 12 in the present embodiment is a release projection that is inclined so that the rear half of the locking projection 12 corresponding to the operating recess 13 is gradually narrowed from the exposed end face side. An operation inclined surface 14 is formed. Thus,
Release operation inclined surface 14 and rear inner edge surface 5a of locking square hole 5
And a wedge-shaped space is formed between them.

In a state where the locking projection 12 is engaged with the locking square hole 5 and the battery holder 16 is held, a relatively sharp tip portion 21 such as a mechanical pen or a ball-point pen 20 is used as in the conventional case. In particular, the inclined surface 2 of the outer peripheral portion reaching the tip portion 21

2. Release of the battery holder 16 and the battery holder 1
The automatic partial projection from the charging port 6 can be simultaneously performed.

Next, the operation of the release of the engagement and the partial protrusion will be described more specifically with reference to FIGS. 1 (A) to 1 (D).

Electronic device main body 2 of card type electronic device 1
1 (A) shows a mode in which a battery holder 16 for accommodating the power supply battery 7 is inserted into the mounting space 3 formed therein and is engaged and held. That is, the battery receiving section 8
The battery holder 16 containing the power supply battery 7 is applied to the tongue piece 9 from the mounting opening 4 of the electronic device body 2 toward the internal mounting space 3 so that the engaging pieces 11a and 11b are elastically opposed. By pushing down while bending it down,
Locking projection 12 formed on the upper end of one engagement piece 11b
Are fitted into the locking square holes 5 by the upward elastic restoring force. In this engagement holding state, the releasing operation inclined surface 14 of the locking projection 12 is opened at an angle α opposite to the rear inner edge surface 5a of the locking square hole 5, and the locking projection 12 In order to be able to smoothly perform the return from the bent state and the re-bending action from the engaged state described below, a required gap β exists between the rear side inner edge surface 5a.

Subsequently, in the state in which the battery holder 16 is engaged and held, the operation of releasing the engagement of the battery holder 16 and automatically projecting a part of the front from the loading port 4 is as follows. Done in

First, as shown in FIG. 1B, the angle α
The tip portion 21 of the ball-point pen 20 or the like as a release take-out jig, and the inclined surface 22 of the outer peripheral portion, are positioned above the inclined portion of the opening. Subsequently, as shown in FIG.
By pushing the front end portion 21 between the release operation inclined surface 14 of the locking projection 12 and the rear inner edge surface 5a of the locking square hole 5, the engaging piece 11b resists elasticity. And the locking projection 12 moves downward, and the engagement gradually starts to be released. In the final stage of the pushing operation, as shown in FIG. 1 (D), the locking projection 12 is disengaged from the locking square hole 5 to release the engaged state, and the rear side of the locking square hole 5 is released. With the upper edge of the inner edge 5a as a fulcrum, the thrust in the perpendicular direction generated between the rear inner edge surface 5a and the release operation inclined surface 14 pushes the release operation inclined surface 14 side, in other words, the battery. A part of the holder 16 on the front side is automatically projected from the charging port 4. Thus, the engagement release and the partial protrusion are simultaneously performed.

On the other hand, by selecting the cross-sectional shape to be set on the engagement piece 11b and the inclination of the release operation inclined surface 14, the vertical pushing force and the lateral direction by the ballpoint pen 20 or the like as the release take-out jig are selected. Can be adjusted arbitrarily.

In the above-described embodiment, the ball-point pen 20 and the like are used as the release and removal jigs. However, similar effects can be obtained by using other equivalent members such as a mechanical pencil. Incidentally, the locking square hole 5 may have an elliptical shape or the like.

Next, another embodiment will be described with reference to FIG.

In the other embodiment, the locking piece 11b and the locking projection 12 have the same shape as the conventional example, and the rear inner edge surface 18a of the locking square hole 18 facing the locking projection 12 is formed as described above. It is inclined toward the upper surface of the locking projection 12 in a direction away from the locking projection 12.

Also in this embodiment, a tip 21 such as a ball-point pen 20 is provided between the locking projection 12 and the rear inner surface 18a.
, The locking projection 12 is pushed in, and the tip 21 is disengaged from the locking square hole 18 by the thrust received from the rear inner edge surface 18a. Is pushed forward. Thus, also in the present embodiment, the ball-point pen 20 or the like is pushed in.
By the operation, the detachment of the engaging protrusion 12 from the engaging rectangular hole 18 and the pushing of the battery holder 17 can be performed simultaneously.

[0024]

As described above, according to the present invention, the non-engaging surface side of the locking projection has a portion facing the inner edge surface of the locking square hole.
Since the releasing operation inclined surface which is gradually narrowed and inclined from the exposed end surface side is formed, the releasing operation inclined surface of these locking projections is engaged in a state where the locking projections are engaged in the locking square holes. By pressing the release take-out jig between the locking square hole and the inner edge surface of the locking square hole, the engagement of the locking protrusion with the locking square hole can be easily released, and the battery holder is operated by a thrust acting during the releasing operation. Can be extruded to the outside.

Further, since the take-out structure is an extremely simple and simple structure in which the operation protrusion is simply formed on the locking projection, the number of required parts is not increased and the take-out structure can be dropped onto a floor or the like. In addition, the battery holder can be easily detached from the main body case, the impact resistance of the battery holder itself can be sufficiently secured, and the structure itself is simple, so that the battery holder can be easily removed. It can be performed with only one touch of the insertion of the tip part, etc., and exhibits excellent effects such as remarkable improvement in workability.
