PURPOSE:To provide the method and device for backing-up a power source so as to deal with the recovery of the power source even when the power source is recovered during a backup processing. CONSTITUTION:This method and device for backing-up the power source is equipped with a voltage detection circuit 6 to detect the voltage of power supplied from a main power source and a CPU to discriminate the ON/OFF of the main power source with the voltage detection circuit 6 again after ending the backup processing started when this voltage detection circuit 6 detects the OFF of the power source, to set a stop state when the main power source is turned off, and to execute a program for a driving state when the main power source is turned on. |
