摘要： In printing heads for a dot line printer, a plurality of which are arranged in line on the reciprocal frame and impact printing wires toward a platen by the driving force of electromagnets excited with the basis of the printing commands, the printing heads for a dot line printer includes electromagnetic actuators including shells which contain and fix cores being wound driving coil around therein and base plates which are attached to the shells in order to close up their opening sides, and forming the tightly closed magnetic loops, and printing springs one ends of which are fixed and supported by supporting portions extended from the base plates, the top ends of which fix armatures at the postion facing to the cores. The printing heads can be unitized, and the close arrangement of the base plates and the armatures can be accomplished by means of direct positioning and fastening of the printing springs to the base plate so that the device can be obtained with excellent maintenance capability as well as small sizes and light weight.

摘要： A method of dot-printing underline or the like employing a print head and power source with relatively small capacity. The reciprocation of the print head is divided into a plurality of travels by the command of divisional print so that the required underline print is performed by the collected dot prints being printed at intervals on each of a plurality of travels of the print head. A rest time will be provided between each printing actions at intervals of the print head to reduce the capacity of a power source employed for driving the dot pins in the print head.

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.
