PROBLEM TO BE SOLVED: To easily find replacement with a microcomputer different from an authentic microcomputer. SOLUTION: An identification information request code inputted through a connector 220 that can be connected to external equipment is inputted to a CPU 56 through a resistor 230 in an interface circuit. Identification information outputted from the CPU 56 can be transmitted to the external equipment through the resistor 230 in the interface circuit and the connector 220. The identification information is selected and outputted in accordance with the kind of the identification information request code. Notification information showing the control clock of the CPU 56 is logically fixed in the main board 31.
