<p>PURPOSE:To speedily restore an information processor by providing a backup power source and a power supply state monitoring part, temporarily shutting-off a processing when abnormality is generated at a power source, and restarting the processing when the power source is normally restored. CONSTITUTION:The power supply monitoring part 2 monitors the state of a supply power source 7 and when the abnormality is generated, it is informed of a CPU 5. Simultaneously, the power source is switched to a backup power source 1. When the supply power source 7 is normally restored, it is informed of the CPU 5 and the power source is switched from the backup power source 1 to the supply power source 7. A temporary shut-off processing means 3 in the CPU 5 shuts-off a processing during execution while receiving the information of the power source abnormality from the power supply monitoring part 2, and stops the supply of power to an external connecting device. A restart processing means 4 restarts the supply of power to the external connecting device while receiving the information of power source recovery from the power supply monitoring part 2, and restarts the stopped processing. Thus, when the power source is restored, the system can be speedily restored.</p> |
