by electromagnetic force in the direction of the arrow 100.
At this time, the armature 32 moves pivotally around the torsion spring 34 center, the stylus 46 supported at one end of the armature 32 is driven and impacted in the direction of the arrow 200 opposite to the direction in which the plunger 50 on the other end of the armature 32 is attracted. Thus, dot printing is effected by the tip end portion of the stylus 46.
However, according to the conventional print head for dot matrix printers, since the armatures having the same structure are arranged in both upper and lower rows, the direction of impact displacements of the armatures is different between the upper row and the lower row because the torsional force of the armatureQ.
