SOLUTION: In an opening portion for storing the battery 1a, a lever 2 and a lever 3 are turnably arranged. When the lever 2 is in the position of a first turning, the first portion of housing the battery (recess 21) and a second portion of housing the battery (recess 11) are formed, while it is in the position of the second turning, a third portion of housing the battery (recess 12) is formed. When the battery is housed in the first portion of housing the battery, the lever 3 is rotated by the stored battery downward to stop housing the battery in the second portion of housing the battery, while the second battery is housed in the portion of housing the battery, the lever 3 is turned by the housed battery upward to prohibit housing the battery in the first portion of housing the battery.
