<p>PURPOSE:To protect processing information by stopping feed after a prescribed information processing required for the protection of the processing information responding to the cutoff of the feed, etc., is performed. CONSTITUTION:A soft power-off switch 15 is operated manually, and a power source circuit 17 is directly turned on by the above turn-on operation, then, the feed to a DC power source 21 is performed. Also, a CPU 1 interrupts a processing under execution at that time corresponding to the turn-off operation of the soft power-off switch 15, and turns off the power source circuit 17 after performing the information processing to prevent processing data from being destroyed or missed due to the cutoff of the feed, then, stops the feed. To perform such power-off processing, a power-off interruption generation circuit 14, an interruption control circuit 13, an interruption status register 10, a power- off control circuit 16, and a timer 9 are provided. In such a way, the processing information can surely be prevented from being destroyed or missed due to the cutoff of the feed.</p> |
