プレコーダのテープテンシヨン制御装置。 A tension pole is erected on a tension arm rotatably supported by a chassis and biased by a spring, and a tape is slid onto the tension pole to vary the rotational position of the tension arm by the tension of the tape. The elastic force of the spring applied to the tension arm and the brake band applies a pressure that is a decreasing function of tape tension to the brake pad slidingly in contact with the tape supply reel stand, and another spring applies a constant pressure to the tape supply reel stand. A tape tension control device for a tape recorder configured to be added to another brake pad in sliding contact with the tape recorder.
