Claims

[Scope of utility model registration request]

A yoke in which a plurality of cores are arranged in an annular shape, a guide member that guides a plurality of armatures facing the cores in a freely undulating manner, an armature presser that comes into contact with a back surface of a free rotation end of the armature, and a rotation of the armature. A dot printer head is provided with a front cover having a needle guide portion that slidably guides a needle connected to a movable end, and the front cover, the yoke, the guide member, and the armature presser are sequentially stacked and combined. A through hole is formed in the center of the needle guide and the armature presser, and the bolt has a head located inside the needle guide and is press-fitted into the through hole of the needle guide. 1. A dot printer head, wherein a nut is screwed onto a tip of the bolt protruding from the through hole of the armature holder.
