ABSTRACT:
A rotary actuator has a Geneva wheel having in one end surface thereof an annular central recess and a plurality of angularly equally spaced and radially extending grooves connected to the central recess, a driving rotor connected to a rotary driving source and rotatable around an axis eccentric with respect to the Geneva wheel, a driving pin mounted on the driving rotor and engaging selectively with one of the grooves and the central recess in the Geneva wheel, an arcuate wall defined on a part of the circumferential wall of the driving rotor, and a plurality of correspondingly shaped arcuate walls formed on the Geneva wheel and cooperating with the arcuate wall of the driving rotor when the driving pin of the driving rotor engages with the central recess thereby preventing the rotation of the Geneva wheel with respect to the driving rotor.
