摘要： A control system for a dot matrix line printer having one print element for each character position on the line; a single-line memory stores the data words for a line of characters and those data words are supplied to a character signal generator sequentially to print the dots for an initial matrix position in a c.times.r matrix for all characters, whereupon the print elements are shifted one column increment along the print line. This procedure is repeated for each dot matrix position, the record sheet being advanced one row increment each time c column positions have been printed. After completion of c.multidot.r scans, printing of a full line of characters is complete, the single-line memory is cleared, and the process is started again for the next line of characters, after a line-space feed of the record sheet.

摘要： A print head for a column-sequential or row-sequential dot matrix printer which prints dots by electrically propelling droplets of ink onto a record comprising a manifold having an ink chamber communicating with a plurality of closely spaced generally parallel ink tubes; a pair of electrodes extends into each ink tube at diammetrically opposed positions to provide a current path through electrically conductive ink in the tube and a magnetic field across the ends of the tubes causes a droplet of ink to be propelled outwardly from each tube whenever the electrodes for that tube are energized.

摘要： A dot matrix line printer incorporates plural print element driver assemblies each including N electromagnets driving N print rods, with each electromagnet having a local magnetic circuit that includes a working air gap and a passive air gap; a permanent magnet is connected to all of the local magnetic circuits. A magnetic circuit connects all of the local passive air gaps in parallel to afford a passive air gap common to all local circuits, the reluctance of the common passive air gap being of the order of 1/N times the maximum effective reluctance of the working air gap of each electromagnet. Each armature is supported by a cantilever bias spring, biasing the armature and associated print rod away from the electromagnet poles toward a print position; a stop member progressively reduces the effective length of the cantilever spring as the armature moves toward the electromagnet poles. A one-piece shuttle engages and guides the outer ends of the print rods; the shuttle includes support arms that are flexible and resilient only in a direction parallel to the dot print line and individual print rod spring guides that are flexible and resilient only in a direction parallel to the print rod axes.
