1.前言数据通信中使用的输入输出设备多种多样,但是可以得到硬拷贝的印刷机则是最基本的设备之一,除了作为键盘印刷机和行式印刷机等通用机器使用之外,还可作为银行出纳机及零售点终端等机器的组成部分来使用。印刷机分为采用机械的方法冲击活字印字的击打式和像感热、墨喷式那样的非击打方式两种形式。击打方式从印字原理上看虽然有噪声大、难于提高速度和可靠性差等缺点,但是由于它使用活字,印字质量好,同时还有可以复写等长处,因此今后仍将是印刷机的主流。这里,设计击打式印刷机的基础是对冲击
1. Introduction There are a variety of input and output devices used in data communications, but hard-copy printers are one of the most basic devices and can be used in addition to general-purpose machines such as keyboard presses and line printers Used as part of machines such as bank teller machines and point-of-sale terminals. Printers are divided into mechanical impact hit type printing method and image-sensitive heat, ink jet-like non-beating two forms. However, due to its use of movable type, good print quality, and the ability to copy and write at the same time, it will continue to be the mainstream of printing machines in the future. Here, the design of the impact press is based on impact
