ABSTRACT:
Herein disclosed is an auto-reverse mechanism for a tape recorder, in which a switching plate is slid by the rotations of a reverse gear adapted to intermittently rotate following the rotations of a motor so that it switches pinch rollers thereby to change the running direction of a magnetic tape. The reverse gear is formed with first and second guide portions which are defined by cam protrusions. A cam plate for imparting an initial rotation to the reverse gear and for rotations in selective engagement with the first and second guide portions is equipped with a drive member for sliding a lock plate for locking a fast forward lever or a rewinding lever so that the lock plate is slid, when the cam plate engages with the first guide portion of the reverse gear, but not when the cam plate engages with the second guide portion.
