Abstract
A series of thin electromagnetic print coils of rectangular shape are arranged in a line overlapped with each other in which each coil is slightly offset from the preceding coil, and are molded together with a plastic material to form a thin elongated coil group. The coil group is bent into the shape of rectangular or rounded "U" to guide therealong a movable member carrying therewith a permanent magnet. Preferably, longitudinally extending parts of windings of the coils are bent outward at right angles to the remaining part of the windings.

A coil means for driving a movable member in a linear motor system comprising a series of electromagnetic coils arranged in a line along a path in which the movable member travels, and energized successively from one at one end thereof to the one at the other end in the direction of movement of the movable member, said series of electromagnetic coils being in the form of thin coils and arranged in a line partially overlapped with each other and fixed together to form an elongated one-piece coil group, and said coil group having a cross-section of a shape of "U" to guide the movable member therein.
