This idea is concerned with a means for converting rotary motion to linear motion by utilizing theattractive/repulsive force of two magnets. A permanent horseshoe-shaped magnet 10 is attached to a rotating shaft 12 and is located opposite to a permanent horseshoe-shaped magnet 14 attached to a sliding member 16 which is constrained to axial motion only. As the magnet 10 on the rotating shaft is rotated, the north and south poles are located opposite of the north and south poles, respectively, of the magnet 14 to repulse the same in one direction away from the rotating shaft, Continued rotation.of the magnet 10 brings the north and south poles thereof oppo-site the south and north poles, respectively, of magnet 14 to attract the sliding member in the opposite direction toward the rotating shaft and thereby provide reciprocal linear mo-tion. Member 16 may be a hammer for an impact printer.
