PROBLEM TO BE SOLVED: To provide electronics which enable batteries to be unloaded readily from storage recessed portions. SOLUTION: When a battery 2 is moved toward a movement space S1, a lower end of a first edge face 2a of the battery 2 mounts on a tilting surface 36 and raises up along the tilting surface 36 as it gets near the first side wall part 2a. Therefore, even if a fixing means 31A is in the storage recessed portion 3, a battery lower end 23 moves above the fixing means 31A, and it is possible to unload the battery 2 by rotating the battery 2.
