The present invention is an auto reverse mechanism for tape recorder/playback devices. In the present invention, if the tape travel in either direction is completed to stop the rotation of the reel turntables, a detector at first detects the halt of the reel turntables through the change-over clutch, and mechanically transmits it to the trigger. The trigger then drives the intermittent drive by the drive force of the drive belt mechanism through the drive force transmission, from a position away from the linkage with the drive force transmission to a position for the linkage with it. Thus, the intermittent drive brought into the position for the linkage with the drive force transmission is driven by the drive force of the drive belt mechanism through the drive force transmission, to drive the a change-over mechanism from one action position to the other action position, as one of its intermittent actions, for actuating the switching action of the change-over clutch and at the same time for selectively detaching either of the pinch rollers from the capstan. Thus, the predetermined automatic change of tape travel direction is released to prevent further driving. Through these actions, the present invention allows the tape travel direction to be changed after completion of tape travel in either direction, by using only the drive force of the tape travel mechanism.
