PURPOSE:To facilitate the exchange of a battery by holding a partitioning plate by regulating an oscillating movement of an oscillating ring at a specified position and forming a housing room capable of selectively inserting and taking out either large and small batteries. CONSTITUTION:In the housing room 27 capable of selectively inserting and taking out the large and small batteries 21, 22, two sheets of a first side plate 41 and a second side plate 43 being aligning in parallel at a specified interval, are provided. The partitioning plate 44 enabling to move in parallel between those plates 41, 43 is supported in freely oscillatably. A rink movement regulating chip 48 to keep the plate 44 at two positions is provided on the plate 41 and the partitioning plate 44 is held by regulating the oscillating movement of the plates 41, 43 at the specified positions with the regulating chip 48. Then the first housing room 27a and the second housing room 27b enabling to insert selectively either large and small batteries can be formed. Thus the operation number at the battery exchange time can be reduced and the exchange of the battery is made simple. |
