ABSTRACT:
A sliding member having an attached tool reciprocates along a guide member. Permanent magnets are placed at both ends of the reciprocating motion path of the sliding member and permanent magnets are also placed in positions on the guide member that correspond to stroke ends of the sliding member. At the points at which the motion of the sliding member reverses, the permanent magnets approach one another and generate a repulsive force, thereby accelerating the sliding member.
