ABSTRACT:
An actuating mechanism which responds to the stoppage of rotation of a component, and a tape recorder inculuding such a mechanism. During apparatus operration a reciprocating movement is imparted to a lever. Rotation of the component causes a frictionally coupled actuating element to press at least one cam against the lever with a biasing torque, the reciprocating movement causing the lever to slide along the cam. The lever also slides along a guide element so as to define a path of lever actuating portion movement. Upon stopping of the component rotation, the biasing torque is removed, and the lever pivots to follow a second path of actuating portion movement defined by the guide element. A tape recorder includes such a mechanism with an actuating element that provides a same torque to the lever for either direction of component rotation, and quickly unlatches control buttons if the component rotation stops.
