Claims

[Scope of utility model registration request]

A single mode changeover switch provided corresponding to a plurality of modes, an encoder that outputs a corresponding mode signal in response to the operation of the mode changeover switch, and an encoder that outputs a strobe signal in response to the operation of the mode changeover switch. A mode switching circuit comprising: a signal generation circuit; and a latch circuit that holds the mode signal by inputting the strobe signal.
