Abstract
The mechanism is primarily for use in the tape drive of a tape recorder for automatically reversing direction of rotation of a pair of rotating members and/or stopping such members through mechanical detection of a sudden variation of load which may occur at the end of taking-up of a tape. A drive roller is supported on a swingable arm for swinging motion to be brought into peripheral engagement with a selected one of the pair of rotating members. Mechanism is provided for causing the swinging motion of the drive roller upon the reversal of rotation of the latter to change its engagement with the rotating members from one to the other. An engaging member is supported concentrically with, and for relative rotation by a predetermined angle to, each rotating member and a coil spring is connected therebetween. The relative rotation of an amount beyond a predetermined value, which is caused by an increase of load, causes the reversal of direction of rotation of the drive roller through actuating mechanism for an electrical switch which controls a drive motor for the drive roller.
