However, in the case of a device that consumes a large amount of power, the size of the rechargeable battery increases in order to extend the continuous use time. In some cases, the dry battery may fit inside the outer shape of the rechargeable battery. FIG. 4 shows this when viewed from above. In such a case, it is impossible to position the smaller battery by the method of providing the cutout in the case as described above.

[0005] It is an object of the present invention to provide a battery accommodating device which can position each of two types of batteries when one of them has a length, a width or a diameter larger than the other.

[0006]

In order to achieve the above object, the present invention provides a first stopper for controlling a position when a first battery is stored, and a first stopper having a longer length than the first battery. ,
A second stopper for controlling the position when a second battery having a large width or diameter is stored, and means for avoiding the first stopper at that time are provided.

With this configuration, when the first battery is stored, the battery inserted into the case is positioned by the first stopper, and when the second battery is stored, the battery is inserted into the case.
The first stopper moves to secure a course, and positioning is performed when the battery enters the second stopper.

In the present invention, the first and second stoppers serve as terminals of the first and second batteries.

According to this configuration, each battery is positioned, and at the same time, the circuit is closed between the other battery and the other terminal attached to the upper lid portion, and voltage is taken out.

Further, according to the present invention, the first stopper avoiding means includes an engaging member that engages with an end of the second battery;
A rotating member for rotating the first stopper to the side wall of the device by the displacement of the engaging member.

According to this configuration, when the second battery is inserted, the battery end comes into contact with the engaging member, and when the second battery further advances, the engaging member is pushed forward while being hooked, so that the rotating member is rotated. Then, the first stopper connected thereto pivots to the side wall portion, thereby securing a path for inserting the battery. The battery goes further in the empty space and
Is positioned by the stopper.
