ド。[Claims for Utility Model Registration] (1) An armature having a printing wire fixed to its tip, a core provided opposite to the armature, a bias spring supporting the armature, and a bias spring wound around the core, In a wire dot printing head consisting of a coil that generates magnetic flux when excited and swings the armature, (a) a residual sheet formed by sequentially laminating a plurality of sheets is disposed between the armature and the core; (b) A wire dot printing head characterized in that among the plurality of sheets, the sheet on the armature side has a larger outer diameter than the sheet on the core side. (2) At least one of the above-mentioned sheets is made of a magnetic material, and among the sheets made of a magnetic material, the surface of the sheet closest to the armature on the armature side or a lubricant coated for wear prevention. 2. A wire dot print head according to claim 1, wherein an oleophobic agent is applied to the surface of the sheet directly facing the wire dot print head.
