Abstract
PURPOSE: To stop motor in a short time after winding of tape, by generating a plurality of pulses with one revolution of reel shaft.
CONSTITUTION: The disc 6 providing a plurality of metal conductors 8 at equal interval is fixed to the reel shaft 4. Further, the brushes 10, 12 are located on the conductor 8 so that they are slid, and the display element 20 is connected to the motor control circuit 26 via the frequency divider 14 and the first counter 16, second counter 30 and switching circuit 22. Thus, pulse is developed with the brushes sliding on the conductor 8 accompanied with the revolution of the reel shaft 4 and the value in response to the number of revolutions of the reel shaft 4 is displayed. Further, since pulse generation interval is short, when the tape winding is finished and the revolution of the reel shaft 4 is stopped, the running end of tape is detected in a short time, allowing the change-over of the rotating speed and direction of rotation, and stopping of motor revolution in a short time.
