Abstract

PURPOSE: To reduce greatly the loss of electric power, by switching the electric contact provided to the current circuit of a motor in order to switch the rotating direction of the motor and then switching the means to be driven in accordance with the rotating direction of the motor.
CONSTITUTION: The relay 44 is connected to the relay driving circuit 42, and the switches 48 and 50 are connected to the contacts 52 and 56 each when no electric conduction is given to the exciting coil 46. Then the current of the P direction as shown in the figure is supplied from the battery 57, and thus the motor 2 is put under the forward rotation mode to drive the tape travelling system. In this instant, no electric conduction is given to the coil 46, and thus the tape can be travelled with no loss of voltage. On the other hand, the relay driving circuit 42 works when the tape reaches its end, and the electric conduction is given to the coil 46 to give a change-over to the switches 48 and 50 each. The switches 48 and 50 are thus connected to the contacts 54 and 58 each, and the current flows in the Q direction in the figure. Thus the motor 2 has a reverse to actuate the lock release mechanism for the push-button.
