摘要： A printer head of improved design for a dot line printer, for high speed data printout. The printer head features independent magnetic circuits for driving each of the printer needles which form printed dots, with the magnetic circuits acting on armatures carrying the printer stylus, the armatures being mounted on the free ends of leaf springs. The leaf springs can be designed for optimum performance, irrespective of magnetic circuit considerations, and the head assembly is based on a lightweight non-magnetic frame. Substantially higher printing speeds than have hitherto been possible are attainable, due to reduced heat buildup in the drive coils, reduced interference between adjacent magnetic circuits, and optimized spring performance.

摘要： A head for an impact type of dot line printer comprising an array of printer wires mounted on leaf springs for forming dots on a printing paper, selectively controlled for impact on the paper by signals applied to corresponding magnetic flux circuit paths comprising coils formed on coil cores and permanent magnets, and having an improved form of construction whereby each printer wire is controlled by an independent magnetic flux circuit path and with pairs of coil cores being mounted on separate magnetic flux path members. The configuration enables a high density of printer wires to be achieved, with elimination of magnetic interference between adjacent magnetic flux circuit paths leading to uniform printing density.
