Abstract

A guide member for print needles and a base plate with guide apertures traversed by the rear end of the needles are bolted to a magnetic core element, having annularly arranged poles; a cover is also bolted thereto, sandwiching a case in between. The cover centers an annular element having radial spring arms which hold one end each of a plurality of armatures respectively against the annularly arranged poles. The spring arm ends and the armature ends have interlinked, raised edges for obtaining a hinged link. The other ends of the armatures engage the rear ends of the needles. The annular element carries the respective electromagnetic coils and cores.
