Since the AA battery holders 81a and 81b and the AA battery holders 82a and 82b are arranged to be orthogonal to each other, the terminal receivers 84a, 84b, 84c and 84d of the AA battery holders 81a and 81b are provided. Each of the AA battery holders 82a and 82b and the terminal receptacles 85a, 85b, 85c and 85d of the AAA battery holders 82a and 82b do not overlap with the AA battery holders 81a and 81b, respectively, in plan view. .
In storing the batteries, referring to FIGS. 18 and 19, the AA batteries 87a and 87b are attached to the AA battery holders 81a and 81b, and the AAA batteries 88a and 88b are attached to the AAA battery holders 82a and 82b. Each is stored. Referring to FIGS. 18, 19, 20 and 21, the AA battery holders 81a and 81b and the AA battery holders 82a and 82b are arranged so as to be orthogonal to each other. The area occupied by the AA batteries 87a and 87b and the area occupied by the AAA batteries 88a and 88b partially overlap. Therefore, the AA batteries 87a and 87b and the AAA batteries 88a and 88b cannot be stored simultaneously.
