<P>PROBLEM TO BE SOLVED: To secure an accessible state to one side storage part, even if impossibility of data storage occurs at different storage parts storing different data respectively. <P>SOLUTION: An EEPROM 5 can read and write important data on apparatus operation through SCL bus 3a and SDA bus 3b. An RFID module 7 can write other data through the same SCL bus 3a and the SDA bus 3b. A CPU 1 controls writing these data selectively to the EEPROM 5 and the RFID module 7 through the SCL bus 3a and the SDA bus 3b. Switch parts SW1 and SW2 cut, with the CPU 1, connection state between the RFID module 7, and the SCL bus 3a and SDA bus 3b, when the CPU 1 can not obtain writing complete information on the EEPROM 5 and the RFID module 7 that are the writing destination. <P>COPYRIGHT: (C)2008,JPO&INPIT |
