Plunger 3 slides in a fixed guide. Lever 4, connected by turning pair B to plunger 3, is actuated by flat spring 5. Lever 2 turns about fixed axis A. Plunger 1 slides in fixed guides p. From chute a workpiece b slides onto fixed surface c. After being machined, workpiece b is ejected by plunger 1, actuated by lever 2, as follows. As plunger 3 descends, lever 4 is pushed back by lever 2. In the return stroke of plunger 3, lever 4, returned to its initial position by spring 5, engages the tooth of lever 2, turning the lever about axis A.
