ABSTRACT:
An automatic stop mechanism for a tape recorder is described. When a magnetic tape has been wound up fully on a reel, slipping takes place between a gear and reel shaft so that the reel shaft stops. As a consequence, a contact portion of a cam follower is caused to separate from a cam surface and a cam is brought into contact with the contact portion. Since the fulcrum of the cam follower is fixed, a turnable lever is caused to turn clockwise so that a gear is separated form the gear. By the turning motion of the turnable lever, its bent end portion presses a lug of a lock member from the right, thereby shifting the lock member leftwards. A head mounting plate is hence released from its engagement with the lock member and is allowed to return to its non-operated position, whereby a magnetic head is allowed to return to its stop position.
