PURPOSE:To prevent a contact failure between a terminal of a power supply and a terminal of a main body. CONSTITUTION:A power supply 1 is attached to a main body 3 with a degree of freedom in the direction in which it is inserted. The power supply is arranged to be slid back by the urging force of a spring 7, so that terminals 2 and 4 of the power supply and the main body are slidably in contact with each other. Since the contact points are always refreshed by a slidable contact when the power supply 1 is attached to the main body 3, a clear contact is ensured between the terminals 2 and 4, thereby preventing a contact failure. |
