<p>PURPOSE: To provide a backup memory control system which can judges whether or not an information stored in a backup memory is the same device startup information as information before the device is powered off by using a control package when the device recovers from the power-OFF state. CONSTITUTION: A replaceable file package 101 is structured by folding the power supply signal line 16 to a flip-flop 14 back outside the collector of the file package 10. A CPU 21 performs startup processing for various set parts 40 on receiving a device startup command and stores the current startup information in the backup memory 11. Once informed that the startup processing ends, the CPU 21 sets a startup information effective flag in the flip-flop 14. The startup information stored in the backup memory 11 is used by the device to restart up itself automatically only when the information effective flag is set, when the devices recovers from the power-OFF state.</p> |
