Magnetic-tape apparatus with improved brake-type tension control

摘要

A bi-directional tape recorder having a single tape tension control device operable in both directions of tape transport. A flexible brake band is wrapped around a braking disc, both ends of the band being secured to the chassis. A tape tension sensing lever presses against a substantially taut part of the brake band between the braking disc and one of the two fixed ends, so that a force exerted by the lever transversely to the brake band produces a change in tensile force in the brake band which is larger than that exerted by the lever.
