Claims

[Scope of utility model registration request]

In a magnetic recording/playback machine that has a tape end detection means and can switch between automatic stop and tape running at the end of the tape, the pinch roller is moved by rubbing against a member that rotatably supports the pinch roller, and the pinch roller is moved to the capsun. A regeneration means to be crimped to the regeneration means, a locking means for holding the regeneration means in a regeneration operation state, an electromagnetic magnet connected to a power source via a switch or the like, and an actuator held when the electromagnetic magnet is energized. is provided, so that when the power source is cut off and no current flows through the winding of the electromagnetic magnet, the actuator of the electromagnetic magnet is activated to self-return to release the locking means, and the pinch roller and capstan are An automatic stop device for a magnetic recording/playback device, characterized in that the automatic stop device is configured such that the two are separated from each other.
