Abstract
A pusher device for pushing plate-form articles such as lead frames including a pusher for feeding out a lead frame, a pusher supporting plate rotatably holding the pusher and having a stopper section that regulates the rotation of the pusher so as to bring a pushing section of the pusher to a lowest position, a coil spring which urges the pusher toward the stopper section of the pusher supporting plate, a cylinder which reciprocates the pusher supporting plate, and a spring-up operation plate which, cooperative with the stopper section of the pusher supporting plate, defines the rotational movement of the pusher. Thus, the pusher is withdrawn from an area into which the lead frame is transferred and then takes a posture to feed the lead frame to, for example, a bonding machine.
