After this, the mechanism 2 is separated from the motor 3, and the motor 3 is coupled to a tape travelling mechanism. Under such conditions, the revolution of the motor 3 is transmitted again to the mechanism 2 through the circuit 4 when a cassette discharge switch is turned on. Then the cassette moves to the discharging position from the loading position. On the other hand, the revolution of the motor 3 is stopped when the switch 5 is turned off in the tape loading mode. Then the cassette discharge switch is turned on, and as a result the power supply is applied to the motor 3 via a terminal 4b. Thus the revolution of the motor 3 is transmitted to the mechanism 2 to discharge the cassette.
