Abstract
A print head for a dot matrix printer in which the printing ends of the print wires are disposed in two parallel rows. A plurality of electromagnetically actuated armatures have their moveable ends connected to the driven ends of the print wires. All of the armatures are of substantially the same length and are disposed radially in an elliptic array so as to minimize the curvatures of all of the print wires. Regions of the print wires intermediate their ends are guided by several guide members housed in a nose member of the head. At least some of the guide members have a pair of arcuate slots therein each adapted to guide approximately one half of the total number of the wires. The nose member is attached to a covered portion of the head by threaded fasteners and a resilient spacer between the nose member and the cover permits the position of the nose member in relation to the printing ends of the print wires to be adjusted by manipulating the threaded fasteners.
