<p><P>PROBLEM TO BE SOLVED: To provide an information processor that automatically restarts even when a main power source is restored during shutdown after power failure, without using an uninterruptible power supply. <P>SOLUTION: The information processor receiving power supplied from the main power source 1 via the uninterruptible power supply 2 includes: a power source unit 3 supplying power to a CPU circuit 42a; a power-on control circuit 41 controlling power supply by the power source unit 3; and a generation part generating a one-shot pulse signal when power supply of the main power source 1 stops and power supply of the power source unit 3 to the CPU circuit 42a stops. The power-on control circuit 41 generates a start-up signal to start power supply to the CPU circuit 42a, when the one-shot pulse signal is input. When receiving power supplied from the uninterruptible power supply 2 and the start-up signal, the power source unit 3 starts power supply to the CPU circuit 42a. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
