ABSTRACT:
A wire printer including a group of substantially straight and parallel printing wires or needles guided at their front ends for longitudinal movement towards and away from a printing station. Each of the printing wires is at its rear end connected to one end of an electromagnet armature the other end of which is supported by a flat spring. The armature cooperates with an electromagnet core provided with a winding. The core as well as the armature consist of strips of magnetic material. The core strips as well as the flat springs are mounted on at least one common rod engaging holes in the rear ends of said core strips and flat springs. The front end of each of the flat springs lies clear of the armature strip and serves, in combination with a stationary rest, to provide a force tending to move the front end of the armature strip away from the core strip.
