Claims

[Claims for Utility Model Registration] (1) A wire guide that is provided on the front surface of a wire printer head and that guides the tip of a wire driven by an electromagnetic drive means through a guide hole, the guide hole of the wire guide being: The wire guide has a tapered shape that becomes narrower toward the distal end surface, and the opening cross section of the guide hole at the distal end surface of the wire guide is slightly wider than the cross section of the wire, and a part of the inner surface of the guide hole is A wire guide for an impact printer head, characterized by having an inclined surface corresponding to an inclination angle. (2) In a wire guide that is provided on the front surface of the wire printer head and that guides the tip of the wire driven by an electromagnetic drive means through a guide hole, the guide hole of the wire guide has two continuous tapered holes. The two holes become narrower toward the center of the wire guide, and the two holes become narrower toward the center of the wire guide.
The connecting section of the two holes is slightly wider than the cross section of the wire, and a part of the inner surface of the hole has an inclined surface corresponding to the inclination angle of the wire, and the one inclined surface is the other inclined surface. A wire guide for a wire printer head, characterized in that the wire guide is shifted by 180 degrees when viewed from the front of the wire guide.
