ABSTRACT:
A magnetic tape recording and/or reproducing apparatus has a motor driven differential mechanism having racks and pinions, an operatively activatable electromagnetic mechanism having movable levers and a plurality of magnetic coils for moving the levers for engagement with the differential mechanism and a tape transport system adapted to cooperate with the differential mechanism so as to be placed in a desired tape transport operation in accordance with the activational condition of the coils. The apparatus also has a pair of one-way clutches for transmitting the driving power of the motor selectively to the differential mechanism or to the tape transport system in accordance with the rotational direction of the motor.
