Abstract
PURPOSE:To exercise the best tension control while driving a take-up reel motor with minimum irreducible take-up torque, by supplying a specific feed-out current to a supply-side reel motor. CONSTITUTION:A driving current for a reel motor 1 at a tape take-up side is detected to supply a feed-out current, which corresponds to the detection output signal, to a reel motor 2 at a tape supply side. In the feedback servo loop, a current limiter circuit 23 which limits the maximum value of the said feed-out current is provided and its operation point is varied according to the rotational frequency of the reel motor 2. For example, the driving current for the motor 1 is detected in the form of a voltage drop across a resistor 21 and supplied to the limiter circuit 23 via a differential amplifier 22. Further, the rotational frequency of the motor 2 is detected by a frequency generator 24 and then converted 25 into a voltage signal, with which the operation point of the limiter circuit 23 is varied.
