PURPOSE:To simplify attaching and detaching of an accessory unit by fixing a bottom plate provided onto the bottom face of a main body case to the main body case by means of screws and storing the accessory unit to a concaved part formed at the inside of the bottom plate. CONSTITUTION:In mounting the accessory unit 6 in the main body case 1, a battery case is removed from the main body case 1 by being slid. Then two screws of the bottom plate 5 of the main body are removed and then the bottom plate 5 is removed, then the recessed part 7 is exposed. The accessory unit 6 is stored in this recessed part 7. Since terminals (c) and (d) come into contact by storing the unit 6, no connection work is required and a printed board or the like in the main body case 1 is not damaged. |
