    摘要： A printing apparatus having a first memory which stores as one unit 8-bit data comprising first data of 6 bits and second data of 2 bits, the first data comprising position data which correspond respectively to printing types formed on the circumference of a rotary printing wheel and which are divided into plural groups, the position data being different from one another in each of the groups and including data common to the groups, the second data being indicative of the urging strength of each printing type when urged against the printing medium; a second memory which stores data for distinguishing between groups to which externally provided character data belong, the second memory storing such distinguishing data for each printing type; and an 8-bit CPU which, in accordance with an externally provided character data, reads out position data and impact data corresponding to that character data from the above first and second memories.

    摘要： An impact line printer having a plurality of high velocity, small mass pivoted print hammers. Both a high print density and an unusually high impact printing force is achieved by actuating the hammers by a corresponding plurality of closely packed solenoids whose diameters are substantially larger than the spacing of the print hammers. These solenoids are mounted in the same vertical space but engage their associated print hammers a predetermined distances S.sub.1 and S.sub.2 from the hammer pivot axis. Appropriate selection of these distances S.sub.1 and S.sub.2 achieves uniform printing pressures from all of the hammers while using identical solenoids and identical drive currents. A paper engaging clamp includes a driven drive roller mounting a pair of resilient O-rings. A pair of pinch rollers, rotatably mounted on pivoted plastic lever arms, are adapted to clamp the paper or other printing medium between the rollers and the O-rings upon application of a force to the lever arms. The resiliency of the lever arm enables print media of varying thickness to be readily incorporated in printers constructed in accordance with this invention. A simplified pawl and ratchet wheel assembly employing a single spring is used to advance the drive roller. A platen sub-assembly comprises a unitary platen member molded of plastic and including a series of comb-like guides for the print hammers. The top surface of the platen supports the printing media within the impact line printer and the plurality of print hammers as well as the pinch roller support arms are pivoted within the platen member.

    摘要翻译： 一种冲击线打印机，具有多个高速，小质量的枢转打印锤。 通过相应的多个紧密包装的螺线管致动锤来实现高打印密度和异常高的冲击印刷力，其直径大大大于打印锤的间距。 这些螺线管安装在相同的垂直空间中，但是使其相关联的打印锤从锤枢转轴线接合预定距离S1和S2。 这些距离S1和S2的适当选择在使用相同的螺线管和相同的驱动电流的同时，实现了来自所有锤的均匀印刷压力。 纸张接合夹具包括安装一对弹性O形环的从动驱动辊。 可旋转地安装在枢转的塑料杆臂上的一对夹送辊适用于在对杆臂施加力时将纸张或其它打印介质夹在辊和O形环之间。 杠杆臂的弹性使得具有不同厚度的印刷介质容易地并入根据本发明构造的打印机中。 使用单个弹簧的简化的棘爪和棘轮组件用于推进驱动辊。 压板子组件包括由塑料模制并包括用于打印锤的一系列梳状引导件的整体压板构件。 压板的顶表面支撑冲击线打印机内的打印介质，并且多个打印锤以及夹送辊支撑臂在压板构件内枢转。
