制動解除手段の動作と共に変位して該テンシヨン
アームと係合し該ブレーキバンドの張力を増す方

部材を設けてなるテープテンシヨン制御機構。 A tension arm that rotates according to the tension of the magnetic tape, a brake band that is displaced by the rotation of the tension arm and brakes the rotation of the supply reel stand, and a brake band that is operated by the brake band when the magnetic tape runs in the opposite direction. In a tape tension control mechanism provided with a brake release means for releasing the brake on the supply reel stand, the tape tension control mechanism displaces and engages with the tension arm with the operation of the brake release means when the magnetic tape runs in the reverse direction. A tape tension control mechanism comprising an engaging member that restricts displacement of the tension arm in a direction that increases the tension of the brake band.
