Abstract

PURPOSE:To reduce the width of drive voltage of a motor, by decreasing an output torque when a tape winding diameter of a reel is small. CONSTITUTION:The tension control of supply and winding side reel motors 21, 22 is made by using differential synthesis circuits 42, 52 through the change of volumes 41, 51 of the respective tension detecting roller. The rotating shaft of the motor 21, 22 is provided with FGs 44, 45, the signal is applied to a differential synthesis circuit 61 from frequency-voltage conversion circuits 46, 56 and also a set voltage from a terminal 62 is applied. The synthesized output of the circuit 61 is applied to a differential synthesis circuit 63, a signal from the FG 64 provided at a capstan motor 23 is applied to the circuit 63 from a frequency-voltage conversion circuit 65 and given to the motor 23. Thus, when the number of revolutions of the reel motor 21 is a specified value or more at fast feed, the synthesized output of the circuit 61 is decreased and control is exercised so that the revolution of the capstan 23 can be decreased.
