Claims

[Claims for Utility Model Registration] The armature on the leaf spring is attracted to the core of the electromagnet by the magnetic flux of the permanent magnet, and by exciting the electromagnet, the magnetic flux of the permanent magnet is canceled and the armature is moved by the reaction force of the leaf spring. A dot printing head which presses an ink ribbon and printing paper against a platen by moving a leading end guide portion of a printing wire attached to a free end of the armature from a guide hole of a guide frame, the dot printing head comprising: 1. A structure of a printing wire for a dot printing head, characterized in that the tip guide portion is formed to have a diameter substantially equal to the printing diameter, and the portion other than the tip guide portion is formed to have a smaller diameter than the printing diameter.
