Filed: 1988-12-16
Abstract: PURPOSE:To cancel the change of a brake torque by stopping the rotation of a rotary input part in a winding reel stand by a lock arm and operating the set torque of a torque limiter in the winding reel stand as the brake torque of the reel stand. CONSTITUTION:At the time of a normal reproducing mode, a cam plate 14 is moved in an arrow direction and a lock arm 17 is turned in the opposite direction of an arrow C by a cam part 14a. Engagement between a lock part 17a and a rotary input part 9a is canceled and a winding reel stand 9 is rotated and driven by an idler gear 11. At the time of a reverse reproducing mode, the plate 14 is moved in an arrow D direction and the arm 17 is turned in the arrow C direction. Then, the lock part 17 a is engaged with the gear of the input part 9a and the set torque of a torque limiter 9f is operated as the brake torque to the reel stand 9. At such a time, tension adding to a tape 4 is the set torque of the limiter 9f and since oil or dust is hardly attached to the limiter 9f, the stable tension can be applied to the tape 4.
