PROBLEM TO BE SOLVED: To accurately operate a normal mode and a mode for down-loading a program by detecting the insertion of a memory card and the turning-on of an original sensor at the time of turning on a power source, and rewriting a program inside a device into a program stored in the memory card. SOLUTION: Whether or not rewriting by an F-ROM should be operated in a state that a power source is turned off is judged, and when it is judged that the rewriting should be operated, an F-ROM card 110 for rewriting is loaded, and when a power source is turned on, whether or not an original sensor is turned on is judged. When the original sensor is not turned on, a normal mode is set, and when the loaded F-ROM card 110 is not for a program, the setting of memory extension is operated, and a normal waiting mode is set. When the F-ROM card 110 is for a program, the memory extension setting is not operated, and the normal waiting mode is set. Also, when the original sensor is turned on, a rewriting mode is set. |
