PURPOSE:To make replacement of old and new batteries possible without interruption of supply current to an electronic circuit by bringing into contact a common contact piece with electrodes of both batteries when old and new batteries are moved. CONSTITUTION:When an auxiliary battery 1c is inserted into a box 2, a new battery 1b and an old battery 1a are moved toward the right, and a contact piece 7 is in contact with positive electrodes 5 of both batteries 1a and 1b, and a contact piece 8 is in contact with negative electrodes 6 of both batteries 1a and 1b, and current is suppried to an electronic circuit from both batteries. By further pushing the battery 1c, the battery 1c is accommodated into a compartment 3b, and the battery 1b is accommodated into a compartment 3a, and the old battery 1a is forced to push out from the box. Therefore, the old battery is replaced to the new battery without interruption of current supply. |
