本文首先简单介绍了国外通用文字发生器的工作原理,指出其缺点是线路复杂,文字象素少字体不逼真,且不能产生汉字,故不适合在我国使用。然后详细介绍了该厂自行研制的文字发生器的工作原理,这种机器克服了上述缺点,能较逼真地显示不同汉字或其它字体,并已在实际设备中使用。 This paper first briefly introduces the working principle of foreign general purpose text generator, pointing out that the disadvantage is that the line is complicated, the characters and characters are not vivid and can not generate Chinese characters, so it is not suitable for use in our country. Then it introduces the working principle of the text generator developed by the factory in detail. This kind of machine overcomes the above shortcomings and can display different Chinese characters or other fonts more vividly and has been used in practical equipments.
