Claims

[Scope of utility model registration request]

a control motor for moving the controlled member to each mode position according to a plurality of modes; a mode selection switch for selecting the plurality of modes; and a control motor for moving the controlled member to each mode position in accordance with the plurality of modes; a signal generation circuit that generates a signal corresponding to the mode; a detection circuit that detects whether the pinch roller is in pressure contact with the capstan; an output of the signal generation circuit and an output of the detection circuit are connected to one input; It consists of a control circuit that rotates the control motor and the reel motor using the control output generated by applying the mode selection switch to the other input and performing comparison, calculation, and judgment, and controls whether the reel motor rotates, stops, or stops. A mode switching device for a cassette tape recorder, which is characterized by eliminating the time lag between pressure contact and Vintilonilla.
