ABSTRACT:
A reversing device for tape recorders includes a pivotable elongate resilient member having one end connected with a reciprocally movable changeover plate so as to move concurrently therewith in a direction perpendicular to the direction of movement of a head mounting plate, and a pivoted central portion movable relative to the head mounting plate in a direction perpendicular to the direction of movement to the head mounting plate. The elongate resilient member has a pair of abutment portions on opposite sides of the pivoted central portion. The head mounting plate has a pair of guide portions engageable with the abutment portions, respectively, in such a manner that in response to the position of displacement of the changover plate, either of the two abutment portions engages a corresponding one of the guide portions to cause the elongate resilient member to pivot in a direction to disengage one pinch roller from the corresponding capstan. The reversing device thus constructed in composed of a relatively small number of components and hence is simple in construction and can be manufactured at a low cost.
