PURPOSE:To enable a smooth printing with a reduction in the friction resistance between a wire and wire guide by varying the angle of mounting the wire to an armature according to the position of the wire within a head. CONSTITUTION:For example, the tip face 14 of an armature 13 is formed slantly and a wire 12 is welded securely on the tip surface 14 keeping it 12 at the angle of theta with respect to the vertical line 16 of the armature 13. This angle theta is determined at the optimum value according to the position of mounting the wire 12 on wire guides 1 and 12. |
