Claims

[Claims for Utility Model Registration] (1) A main rotating wheel that rotates in both directions, and a swing shaft coaxial with the rotation axis of the main rotating wheel, which swings in accordance with the rotational direction of the main rotating wheel. A swinging member having a driven rotating wheel that selectively transmits power to the take-up reel shaft or the unwinding reel shaft, and even when the driven rotating wheel is rotating, the power from the driven rotating wheel is A brake mechanism for a tape running device, comprising a swinging member holding means for holding the swinging member as necessary in a position where transmission is not transmitted to any reel shaft, and a brake member provided on the swinging member. (2) The brake mechanism for a tape running device according to claim 1, wherein the main rotating wheel and the driven rotating wheel are comprised of gears. (3) The brake mechanism for a tape running device according to claim 1 or 2, wherein the brake member has a foot made of an elastic member. (4) The winding and unwinding reel shaft has a gear to which power is transmitted from the driven rotating wheel, and the brake member is interlocked with the swinging member holding means and is interlocked between the teeth of the gear of the reel shaft. A brake mechanism for a tape running device according to any one of claims 1 to 3, characterized in that the brake mechanism is comprised of a locked wire spring.
