Abstract
PURPOSE: To increase the tension control accuracy, by removing the tape tension due to reel drive motor.
CONSTITUTION: Between the input terminal and ground of the reel motor drive circuit 3, the transistor 6 and the resistance 5 to subtract a given amount of torque corresponding to the mechanical loss of the reel motor 4 from the output of the torque reference voltage generating circuit 1 are connected in series. Thus, after the output of the torque reference voltage generating circuit 1 is adjusted with the variable resistor 2, it is given to the reel motor drive circuit and when the reel motor 4 is turned, the tape tension due to mechanical friction torque specific to the reel motor 4 is eliminated to enable tape tension control with good accuracy.
