Claims

[Scope of claim for utility model registration] An armature with a printing wire fixed to the tip,
a core provided opposite to the armature; a bias spring supporting the armature;
In a wire dot printing head consisting of a coil that is wound around the core and swings the armature by generating magnetic flux when excited, (a) an oil felt is disposed near a guide that guides the printing wire, and (b) (c) A wire dot printing head characterized in that the oil felt is formed of a rectangular member having a hole in the center for passing the printing wire through, and (c) a slit extends from the hole to the periphery.
