Abstract
Disclosed is a magnetic recording and reproducing device which comprises a reversible motor, a first gear fixed to the shaft of the motor, a second gear and a pulley rotatably supported by the shaft of the motor, a first one-way clutch for transmitting the torque of the first gear to the second gear only when the motor is operating forwardly, a second clutch mechanism for transmitting the power of the first gear to the pulley only when the motor is operating backwardly, a cassette transfer mechanism engageable with the first gear, a magnetic tape running mode switching mechanism engageable with the second gear, and a magnetic tape running mechanism engageable with the pulley, whereby a plurality of mechanisms are driven by a single motor.
