Abstract

PURPOSE:To protect a memory circuit by providing a solar battery in the position where it receives light only when an opening-closing member for battery exchanging is opened and using this solar battery as a backup battery for the memory circuit. CONSTITUTION:A solar battery 3 is provided in the position where it receives light when the hatch cover of a battery hatch 4 is opened, whereby the memory volatilization during the time when a battery 1 is mounted or dismounted is prevented.
