Abstract

A needle printing device having a plurality of printing needles mounted in electromagnets with a permanent magnet operating through a yoke to retain a spring upon which the needles are mounted against the core of the electromagnet, the spring having an armature thereon which is released when the electromagnet is energized to permit the needles to be driven into printing position by operation of the spring. The particular features of the invention involve a construction wherein the yoke means is formed in two parts, with the first part having a surface which is formed in a common plane with a surface of the core of the electromagnet, the second part of the yoke having a surface which lies in a common plane with a surface of the armature when the electromagnetic is de-energized with the armature held against the core of the electromagnet.
