Abstract
PURPOSE:To keep tape tension constant, by controlling the turning of a tension control lever by detecting the turning corresponding to the tension of a tension detecting lever. CONSTITUTION:When the tension of a tape 1 is increased, the tape is pressed by a spring 5 with a small spring constant, and balancing between torque from the tape 1 is maintained, and the tension detecting lever 3 set at a stationary state is turned in a direction of arrow A. The turning is detected by a position detector 7, and a detected result is supplied to a control circuit 11, and a driving device 10 is controlled via the circuit 11, and the tension control lever 8 is turned in a direction of arrow D, then, the tension of the tape 1 is decreased. When the tape tension is decreased, the tape tension is adjusted similarly, thereby, the tape tension can be kept constant even when micro fluctuation is generated.
