Abstract
A dot matrix print head wherein each printing device comprises a pin fitted to one end of the anchor of a respective electromagnet. The electromagnet presents an E-shaped core, the center bar of which forms a first pole piece, and the other two bars of which form the other pole piece coplanar with the first. The anchor consists of a plate having a flat surface designed to rest on the first pole piece and defined by two parallel steps. The first step is located on a portion opposite the end fitted with the pin, and rests on the other pole piece. The other step is adjacent to the aforementioned end, and corresponds with the gap between the center bar and a lateral bar of the core, so as to enable overtravel of the plate and the pin for effecting a ballistic print stroke.
