ABSTRACT:
A wire matrix print head comprised of a plurality of impact print wires or styli, each having an input end for receiving an impact and an output end for delivering an impact to a record medium through an inking ribbon. The impact end of said wires or styli are arranged in a specialized elliptical format while the output end of the wire styli are formed into a planar straight line configuration, thus providing for a minimal amount of bending arc along the length of the styli. This configuration permits direct transmission of the impact forces to the output end and permits each stylus to be of equal length to the other styli. Efficacious provision is made for adjusting the stroke length of each stylus even though a uniform electromagnet for each stylus is used to provide the activating or impact impulse.
