リンタ。[Claims for Utility Model Registration] An armature assembly consisting of an armature, a lever, a wire, and a spring with one end fixed;
It has a coil, core, and magnet that constitute a magnetic circuit for attracting and releasing the armature assembly, and the wire is driven by a spring force that is attracted by the magnetic force and restored when the magnetic force is released, thereby performing dot matrix printing. In a wire dot printer equipped with a release type print head, a guide is provided in the non-printing direction of the wire portion at the tip of the lever to prevent the wire and the lever from swinging laterally and to guide the wire to a predetermined position. ,
A wire dot printer characterized by being attached.
