PURPOSE:To package an armature fitted with a plunger, hence a wire at a high density by shaping a plunger to be cut at opposed parts on the circumference of a cylinder while the fitting hole of the plunger on the auxiliary yoke is shaped in the same form. CONSTITUTION:A plunger 46 fixed on an armature 43 gives a sectional shape having a cut at both sides of a cylinder as well as a core 6 and the throgh hole of the plunger formed in an auxiliary yoke 40 is shaped in the same form. The core and the plunger are packaged at a high density and a multipin is used to obtain a small wire dot head excellent in the efficiency of power-printing force conversion. |
