PURPOSE: To simplify an operation of the time when editing a tape by controlling a motor of a sound recording and reproducing mechanism in accordance with an operation of a reproduction-only mechanism by a transistor.

CONSTITUTION: A collector of a transistor 9 is connected to a plus side of a motor 2, and its base is connected to the earth by a resistance 10 and also connected to a rewinding switch 5 through a resistance 11. When a sound recording button of a sound recording and reproducing mechanism 13 is pushed, a voltage is applied to the motor 2. In this case, since the transistor 9 is off, no voltage is applied to the base of a transistor 7, and this motor 2 is not operated because it is not grounded. When a tape completes rewinding by a reprodution-only exclusive mechanism, this reproduction-only mechanism becomes a reproducing state, the rewinding switch 5 becomes off, the transistor 9 becomes on since no voltage is applied to the beae, a voltage is applied to the base of the transistor 7, the transistor 7 also becomes on, the motor 2 is connected to the earth and starts its operation, and a reproducing signal from the reproduction-only mechanism is sound-recorded.
