摘要： A dot matrix print head has a print wire unit having a plurality of print wires, an armature unit having a plurality of armatures, each corresponding to the print wire, and an electromagnet unit having electromagnets. Each wire comprises a wire body and a head. A return coil spring is provided between the head of the print wire and a guide plate. The return coil spring has a small diameter end portion engaged with the head and a large diameter portion engaged with the guide plate and has a substantially conical peripheral shape. The large diameter portion engages a recess, thereby preventing rotation of the spring.

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.
