摘要： An impact type dot matrix printing head in which a plurality of dot printing elements, each of which is formed of a thin flat sheet material, are stacked in the direction of their thickness and each being capable of sliding relative to one another when actuated. The dot matrix printer arrangement is such so as to efficiently add to the number of dot printing elements making up a given matrix so as to increase the density of the multiple dots to form more legible characters, to reduce the size and weight of the dot matrix printer, and to improve its durability. A plurality of electro magnets for individually actuating a corresponding associated dot printing element are circumferentially spaced in one or more stages spaced longitudinally along the dot matrix. In one form of the invention an intermediate portion of the respective dot printing elements are offset or oppositely deviated to reduce wear and/or resistance between adjacent dot printing elements.
