Abstract

Improvements introduced in printers, which include at least one print head, particularly of the needle type, these needles being intended to strike a support, in order to print, on this support, selected dots of a matrix of dots, to the object representing, with these selected points, figures, characters or the like, also including carriage members that support said head and control elements for the movement of carriage members in a longitudinal direction, the ends of said needles being arranged according to a line substantially perpendicular to said longitudinal direction, characterized in that the carriage members include two end walls and that said printer includes elastic elements, capable of working together with said end walls and with the printer frame, when object of which, at the extremities of the career of the organs of car ro, the speed of the latter varies appreciably sinusoidal when they reverse their direction of travel, so that the said speed of the carriage members, according to the longitudinal direction, in one direction and in the other, remains constant in the rest of the stroke of the aforementioned carriage members, whereby the printing of figures, characters or the like by said head, is carried out at the moment of said displacement, at a constant speed.
