Claims

[Scope of utility model registration request]

A mode switching slider, a brake release arm that engages with the cam of this slider and rotates forward as the slider moves, and a brake release arm that engages with this brake release arm and resists the urging means by the forward rotation of the brake release arm. a brake release slider that moves forward, a reel stand brake that is released by the forward movement of the brake release slider, and a lock lever that is actuated by power to lock the brake release slider in its forward position; The release arm and the brake release slider are connected to each other via a biasing spring, and the engaging portion of both is configured to allow the brake release arm to independently rotate back when the brake release slider is in the return position. It has play that allows it to rotate in the direction,
When switching to stop mode, the lock by the lip lever is released, the brake release slider moves back to the predetermined position, and the brake release arm also moves back to the predetermined position. A mode switching device for a recording/reproducing apparatus, wherein the cam of the mode switching slider that moves backward is further rotated independently against the urging spring to return to a predetermined original position.
