Claims

[Scope of utility model registration request]

A mode switching slider, a brake release slider that engages with the cam of this slider and moves forward against the urging means by the movement of the slider, and is released by the forward movement of the brake release slider and released by the backward movement. and a lock lever that can be rotated by power to lock the brake release slider in its forward position, and the brake release slider is held in its forward position by the cam. The recording and reproducing apparatus is configured such that when the switching state is changed to the stop mode, the lock lever is locked in the forward movement position, and the lock is released when the mode switching slider almost returns to the stop mode position. Mode switching device.
