ABSTRACT:
In order to restrain a flux loss for obtaining magnetic characteristic required for high-speed printing, a wire dot printer head has armature4having a pivot shaft serving as a center of a pivot and pivotably provided so as to oppose to plural cores formed on a yoke and an armature spacer provided on the yoke for forming a side magnetic path with respect to the armature, wherein, supposing that each of the saturated magnetic fluxes of the yoke, the armatures and the armature spacer is defined as A, B and C in this order, these components are formed to establish a relationship of A≧B≧C.
