<p>PURPOSE:To prevent a backup device to be loaded onto an auxiliary device such as an IC card from being dropped or forgotton to be loaded. CONSTITUTION:A plus electrode 12 and a minus electrode 11 for loading a backup battery 1 are elastically (with spring property) formed on a battery case 10 to be loaded onto the IC card 20, the battery 1 is held by the electrodes 11, 12 to prevent the battery 11 from being dropped, and when the battery 1 is not stored in the case 10, the electrodes 12, 11 are short-circuited and the electrode 11 is grounded. Thereby if the battery 1 is forgotton to be loaded onto the card 20, the battery absence state is detected by an external electronic apparatus which is not shown to inform the forgotton state of battery loading.</p> |
