Abstract: A wire matrix print head is disclosed including a plurality of print wires movable through supporting guides between print and non-print positions, springs urging the print wires toward their non-print positions with separate rigid armatures being movable by respective electromagnetic units from a rest position toward a print position for engaging a respective print wire and driving it toward and into its print position. A housing for supporting and accurately positioning the print wires, armatures and electromagnetic units relative to each other includes multiple portions which are interconnected in spaced apart relation about their peripheries in order to establish and maintain accurate positioning of the armatures relative to the respective electromagnetic units and print wires.
