ABSTRACT:
A wire matrix printer mechanism is designed to print a series of alpha-numeric characters and symbols by mechanically impacting an inked ribbon with a column of small diameter steel wires, driving the ribbon into paper riding on a platen. The body through which the print members pass is a molded structure having a separate channel for each print member. Each channel has a path consistent with the elastic curvature of the corresponding print member to provide a path of least resistance.
