Claims

[Scope of utility model registration request]

(1) A motor for moving the tape recorder mechanism to each position of a controlled member according to a predetermined mode, a mode switching operation section for switching the tape recorder mechanism to a predetermined mode, and a motor that is linked to the mode switching operation section. a signal generator that detects the operating mode and generates a corresponding digital signal;
Mode selection input section Sσ] Inputs a mode signal and a digital signal from the signal generator, performs a comparison operation, and performs the mode switching operation to switch the tape recorder mechanism to a mode corresponding to the mode signal. A mode + JJ conversion device for a tape recorder, comprising: a control circuit for giving commands to the motor; a motor forward/reverse control circuit for rotating the motor; and a motor rotation speed servo circuit for controlling the rotation speed of the motor.

(2) In a device in which the operating mode is switched by rotating the motor, the motor is rotated at high speed until a predetermined mode is reached after mode switching, and after reaching the switching mode, the motor is rotated at low speed. The mode switching device for a tape recorder according to claim 1, characterized in that the mode switching device for a tape recorder is configured to perform switching control as described in claim 1.

(3) A utility model characterized in that, in a tape recorder in which the opening and closing operation of the cassette door is performed by a power motor for mode switching, the rotation of the motor is controlled to a lower speed when opening and closing the cassette door than when switching other modes. A mode switching device for a tape recorder according to claim 1.
