The apparatus includes a stop signal generator for generating a stop signal to be used for stopping the reel and a stop pulse generator circuit for simultaneously supplying stop pulses of the same phase to respective phases of the stepping motor to which the drive pulses are supplied. All of the respective phases of the motor are simultaneously magnetically excited responsive to the stop pulses received by the stepping motor.
