随着电子计算机的不断发展,对高速印刷装置,特别是对高速图形印刷装置的需要日益迫切。目前使用的打印机和绘图装置,由于机械方面的原因,进一步提高速度(如打印机超过20行/秒)存在一定的困难,因而希望采用新型印刷装置,逐步代替机械式印刷装置。为此而研制的新型印刷装置种类很多,但比较起来,静电印刷装置更适合于在电子计算机中采用。静电印刷装置的特点如下:1.能高速印刷字符和图形;2.工作噪音小;3.可靠性高;4.结构简单。本文拟对静电式印刷装置作简单的介绍。一、静电记录的基本原理静电记录是采用带电和静电吸附的原理形成图象或字符的一种方法。在记录媒体上加一 With the continuous development of electronic computers, the demand for high-speed printing devices, especially for high-speed graphic printing devices, is increasingly urgent. The currently used printers and plotters have some difficulties due to mechanical reasons such as further increase in speed (for example, printers exceeding 20 lines per second), and therefore, the desire to adopt a new type of printing apparatus to gradually replace the mechanical type printing apparatus. There are many new types of printing devices developed for this purpose, but in comparison, electrostatic printing devices are more suitable for use in electronic computers. Electrostatic printing device features are as follows: 1. Can print characters and graphics at high speed; 2. Working noise; 3. High reliability; 4. Simple structure. This article intends to make a brief introduction of the electrostatic printing device. First, the basic principle of electrostatic recording Electrostatic recording is the use of charged and electrostatic adsorption principle to form a method of image or character.
