ABSTRACT:
Two cylindrical stator magnetic poles are disposed with a suitable space therebetween, and a plunger is movably disposed within the two stator magnetic poles. A coil is wound around the outer periphery of the two stator magnetic poles, and a current flowing in the coil causes the plunger to advance forward. The current flow is interrupted before the plunger reaches the intermediate position between the two stator magnetic poles, and the plunger thereafter further advances by inertia and strikes a ball. After the ball is struck, the coil is again supplied with a current, and the plunger is in turn supplied with a magnetic force in a retreat direction.
