<P>PROBLEM TO BE SOLVED: To solve the problems wherein although a method to write information to be stored in the address of an EEPROM is commonly used, when a system is shut down, as a means to store the operation information of a device, there is an anxiety to fail to store any accurate operation information owing to any unexpected power failure or the operation mistake of a user, and wherein although there is a method to store the operation information in the memory each time the operation information is changed as countermeasures to this problem, there are many cases that it is impossible to use this method since the guaranteed number of times of the storage memory (the life of the storage memory) is not enough for the life of this device. <P>SOLUTION: An operation information storing means is provided with an "operation information storage page managing means" to store an operation information storage area for a plurality of pages, and to execute the old and new management of the storage area for those plurality of pages. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
