A plurality of the magnetic paths are arranged radially in parallel, and an armature fixed to the tip of a leaf spring whose base end is fixed is disposed so as to be displaceable within an armature housing portion of an auxiliary yoke connected to the magnetic gap of each magnetic path. facing one end surface of the inner leg;
Moreover, in the dot printer head in which a printing wire is fixed to the armature, the planar shape of the armature is a rectangle smaller than the trapezoidal wide part of the inner leg piece and wider than the narrow part, and one end surface of the inner leg A dot printer head obtained by removing the non-polymerized portion of the alumina.
