Abstract
A dot matrix print head is described having an improved type of electromagnetic actuator device for the print needles; the ends of the striker elements which cooperate with one of the poles of the electromagnetic drive for each needle are in fact shaped on the side facing the said pole, in such a way as to be displaced with respect to the point of contact of the striker element on the pole itself, so as to cause between this end and the pole a predetermined clearance capable of compensating possible constructional imprecisions. (FIG. 2).
