Abstract
PURPOSE: To suppress the excessive movement of the reel motor, by using the tachometer connected directly to the reel motor to feed back rotation speed fluctuation components of the motor.
CONSTITUTION: Tachometer 23 is mounted on reel motor 22, and the output is appllied from speed voltage converting circuit 29 to comparator 30, and the error signal between this output and reference voltage SG is supplied to adding circuit 31. The output voltage from tension arm position sensor 28 as well as the signal from speed fluctuation detecting circuit 33 are applied to adding circuit 31 to control motor driving circuit 34. Speed fluctuation detecting circuit 33 controls switching circuit 39 by rotation direction detector 35 and is so controlled that feedback of speed fluctuation components is always negative, and the output voltage of speed voltage circuit 36, same polarity amplifier 37, or inversion polarity amplifier 38 is always fed back with the correct polarity.
