Claims

[Scope of utility model registration request]

In a device for recording and reproducing signals on a running magnetic tape, a worm gear mechanism is used to rotate a rotary cam body in forward and reverse directions, which sets the mode of the device according to its rotational position. , the worm is movably supported within the worm gear mechanism and is movable in the axial direction when the worm starts rotating, and when the worm gear mechanism starts operating when converting the device from the tape running mode to the stop mode. A reel of a magnetic tape recording and reproducing device, in which an axial displacement of the reel releases a reel-disk braking mechanism that is locked in a reel-disc braking release state against a spring bias in a reel-disk braking direction. Disc braking device.
