A battery accommodating device comprising a pair of contacting battery contacts, wherein one of the battery contacts comprises a first contact and a second contact contacting each of the two types of batteries. The two contacts are mounted on a first surface and a second surface which are orthogonal to each other and are located at different distances from the rotation fulcrum of the contact case in the contact case rotatably attached to the body case. A rotation operation portion of the contact case is provided on the first surface far from the rotation fulcrum, and the first contact is covered by the main body case when the second contact is exposed in the storage recess. Characterized by being It is intended.

[0007]

According to the present invention, the contact case is rotated in accordance with two types of batteries having different lengths so that the distance between the battery contacts in the storage recess matches the length of the stored battery. Is changed to.
