    • A print wire driving device for a wire dot printer includes a plate like member having slots therein. The slots are arranged opposite the cores of a magnetic core block. The cores are arranged in a circle and project from the core block. The slots extend radially from the center of the plate like member. A magnetic driving member is received in each slot so that it pivots therein when acted upon by the magnetic field of a respective magnetic core. A print wire is coupled to each magnetic driving member. Each print wire is guided by a wire guide having a wire nose which receives at its end a wire guide member from which the ends of the print wires extend to print. The wire guide includes structure for properly aligning two stacks of magnetic actuators.
    • 一种用于丝印打印机的打印线驱动装置包括其中具有槽的板状构件。 槽与磁芯块的芯相对配置。 芯部设置成圆形并从芯块突出。 槽从板状构件的中心径向延伸。 磁性驱动构件被容纳在每个槽中,使得当磁性驱动构件在相应的磁芯的磁场作用时枢转。 印刷线耦合到每个磁性驱动构件。 每个打印线由具有电线头的导线器引导,导线端部在其端部接纳线引导构件,印刷线的端部从该线引导构件延伸以打印。 导线器包括用于正确对准两个磁性致动器堆叠的结构。

    • An improved wire dot print head assembly for a wire dot printer including a resilient securing spring for holding the assembly elements secure is provided. The print head assembly includes a plurality of print wires, each selectively driven through a print nose by a plurality of electromagnets disposed about the print wires. A pivotable operating member engaged to the input end of the wire is actuated by an electromagnet with the fulcrum end of the operating member secured by a holding member. The holding member, nose, electromagnet and operating member are compressively retained by the resilient securing spring. The holding member is formed with a projection extending through the fulcum portion of the operating member to minimize magnetic reluctance of the magnetic flux by minimizing an air gap between a plunger mounted on the operating member and a yoke plate. The print head constructed in accordance with the invention permits improved dimensional accuracy in a simplified construction.
    • 提供了一种用于线点打印机的改进的线点打印头组件,其包括用于保持组装元件固定的弹性固定弹簧。 打印头组件包括多个打印线,每个打印线通过布置在打印线周围的多个电磁体选择性地驱动通过打印头。 接合到线的输入端的可枢转操作构件由电磁体驱动,其中操作构件的支点由固定构件固定。 保持构件,鼻子,电磁体和操作构件被弹性固定弹簧压缩保持。 保持构件形成有延伸穿过操作构件的支点部分的突起,以通过使安装在操作构件上的柱塞与轭板之间的气隙最小化来最小化磁通量的磁阻。 根据本发明构造的打印头允许以简化的结构改进尺寸精度。
