Abstract
The invention provides a process for producing a dot printer head wherein a plurality of needles having their ends arranged along a straight line have gradually increasing lengths towards opposite outer end ones thereof so that when the needles are being inserted into respective needle holes in a needle guide, they can be positioned one after another each under the guidance of a needle located outwardly adjacent thereto. Thus, even where an arrangement of needles is such that there remain some gaps between adjacent needles, the needles can be guided one after another beginning with the outermost ones thereof and be inserted smoothly into the needle holes.
