Abstract
A wire matrix print head having print wires subject to wear at their printing ends are biased by return springs against one side of one end of armatures, the other sides of which bear against a gap adjusting ring. The other end of each of the armatures is spaced by a predetermined gap from the pole piece of associated electromagnets which, when energized, drive the armatures about pivots intermediate the ends of the armature against the bias of the return springs. The ends of the armatures are formed with a step on the side initially placed in contact with the drive end of a print wire so that when the print wires are worn the armatures can be flipped over to present the unstepped side in contact with a drive wire with the result that upon movement of the adjusting ring to restore the gap between the armature and pole piece the print wires are pushed to a rest position closer to the printing plane by the depth of the step.
