Abstract
A wire matrix print head for a dot matrix printer employs a plurality of electromagnetically actuated print wires converging forwardly through a wire guide member for termination at their leading ends in confronting and adjacent relation to the print medium. The trailing ends of the print wires are mounted within electromagnetic actuators for movement in a lengthwise direction to cause their leadings ends to be driven into the print medium to form a series of even impressions or dots thereon, the print wires being displaced at equal included angles between adjacent print wires. The wires diverge in different directions along equal radii of curvature preferably corresponding to their elastic curves from their leadings ends toward the trailing ends whereby to minimize frictional surface engagement in supporting the wires for movement into the print medium under an equal degree of force to assure uniform impressions or dots in forming each character or symbol.
