Claims

[Scope of utility model registration request]

A rotary dial plate that automatically returns to a predetermined initial angular position, a means for detecting the rotational angular position of the rotary dial plate, and an operation control means that operates according to a detection output obtained from the detecting means, When it is determined that the detection output for detecting the angular position remains the same for a predetermined period of time, a predetermined operation mode is specified,
A rotary dial position detection processing circuit, characterized in that a determining means is provided to maintain the current operating mode when it is determined that the rotation dial position is different.
