、電源供給が断たれるとメモリーが消えてしまう回路へ
バックアップバッテリーより電源を供給してメモリを保
持し、全回路を入切する電源スィッチが切のときは、電
源供給が断たれてもバックアップバッテリーよりの電源
供給は行なわないことを特徴とするバックアップバッテ
リー内蔵メモリ回路付電子機器。A power supply that turns on and off all circuits by supplying power from a backup battery to circuits whose memory will be erased if the power supply is cut off, preserving the memory only when the power switch that turns on and off the circuits of electronic equipment is on. An electronic device with a built-in backup battery and a memory circuit, characterized in that when the switch is turned off, power is not supplied from the backup battery even if the power supply is cut off.
