Arrangement for varying the tape tension in a magnetic-tape apparatus

摘要

An arrangement for varying the tape tension in a magnetic-tape apparatus includes a pivotably supported sensing lever (15) whose free end is pressed against the magnetic tape (14) under the influence of a spring (16) and, upon deflection from a neutral position (15'), is reset to its neutral position (15') by a control device (17, 18) through a variation of the tape tension. In order to enable the tape tension to be rapidly reduced for operation in the stand-by mode, an actuating mechanism (20) can be activated separately and includes a resilient actuating lever (22) which extends into the pivoting range of the sensing lever (15) upon activation of the actuating mechanism (20) and causes this sensing lever to be deflected in opposition to the force acting on the sensing lever (15).
