摘要： A dot matrix printer system utilizes a reciprocating shuttle having a plurality of hammer elements and externally energized hammer controls mounted with the hammers on the shuttle. Each hammer scans a number of dot printing positions within a dot matrix line, and is energized at a high repetition rate during movement to imprint serially the dot patterns in that line for several successive characters. The paper is then advanced and the next dot matrix line is printed in the reverse direction. The shuttle mechanism forms a part of a dynamically balanced system, being in one example driven in a trapezoidal motion from a cam system that also engages an oppositely moving counterweight system. A highly reliable fast acting hammer bank comprises an array of individual spring hammer elements and associated magnetic actuators, the hammer elements normally being magnetically biased to a retract position by a permanent magnet. The magnetic field is neutralized to permit hammer flight with controlled velocity for imprinting, with hammer return being automatically achieved by the magnetic bias. The system is amenable to generation of a wide variety of dot matrices and arbitrary printing patterns, and provides uniform and well defined characters through a substantial number of copies, but nevertheless operates reliably and at high speed with a low cost mechanism that does not require adjustment.

摘要： A printer/plotter system for producing a multiple color hard copy output in response to digital input data. The system includes one or more impact hammers, each capable of printing a single dot with the hammers being arranged to selectively print dots along a defined print line. The system further includes an ink ribbon having multiple zones of different colors carrying encoded identifying indicia. In response to input data defining a dot pattern and the color in which it is to be printed, the ribbon is searched to position the first identified ribbon color zone in front of the impact hammers. After the pattern for that color is printed, the ribbon is again searched and the next identified color zone is moved into the print station, i.e. in front of the impact hammers, and the pattern associated therewith is printed. A paper control system is provided to move the paper to be printed upon in a forward direction as information is printed in each color. The paper control system is also operable to move the paper in a reverse direction to reposition the paper for subsequent movement in a forward direction as information is printed in a different color.

摘要： A dot matrix printer having a reciprocating hammer bank prints characters in either a standard or a compressed size using one of two different sets of modulation bits stored in a character generator for each character. A control code byte preceding each line of characters to be printed selects the sets of modulation bits in the character generator to be used and in addition selects the repetitive counts to be made by two different decoders in response to timing pulses designating the different dot column positions during each sweep of the hammer bank to control the application of the modulation bits from the character generator to actuating mechanisms for the hammers within the hammer bank. The compressed characters are the same height as but of reduced width compared to the standard characters, with the result that each hammer in the hammer bank prints a greater number of compressed characters than standard characters while bidirectionally reciprocating through a fixed distance relative to a paper or other printable medium.
摘要翻译：具有往复锤组的点阵式打印机使用存储在每个字符的字符发生器中的两组不同调制位之一来以标准或压缩尺寸打印字符。要打印的每行字符之前的控制代码字节选择要使用的字符发生器中的调制位集合，并且另外选择响应于指定不同点列位置的定时脉冲由两个不同解码器进行的重复计数在锤片组的每次扫描期间，控制将字符发生器的调制位应用到锤组内的锤的致动机构。与标准字符相比，压缩字符的高度与宽度减小相同，结果是锤子组中的每个锤子比标准字符打印更多数量的压缩字符，同时相对于纸张双向往复移动一定距离，其他可打印介质。

摘要： A dot matrix line printer/plotter apparatus for producing hard copy printout of digitally represented data. The apparatus utilizes one or more hammer banks, each mounted so as to shuttle across a paper web fed therepast. Each hammer bank carries a plurality of hammer assemblies, each of which can be individually actuated to print a dot as it sweeps across the paper. Each hammer bank is mounted on a circuit board which carries electronic circuitry to actuate the hammer assemblies thereon. The circuit boards are supported by leaf springs and driven by a stepper motor which shuttles the boards along linear paths to sweep each hammer assembly across a certain portion of the paper width. Each hammer assembly includes a hammer supported in a guide tube for linear movement between a retracted position and an extended position engaging the paper. A permanent magnet is provided to normally latch the hammer in its retracted position. Each hammer assembly further includes a coil energizable to null the action of the permanent magnet as to that hammer assembly and to thus permit a spring to propel the hammer to said extended position.
