一、前言1959年世界上出现了第一台能自动连续复印的普通纸静电复印机,即美国施乐(Xerox)914型复印机。此后,人们一直为实现复印机小型化这一目标而努力。当时的914型是复印机小型化的一大成果,因为在那之前,世界上只有手动、半自动的笨重大型平板机。今天,复印机小型化又结硕果,以(?)提式复印机和携带式超小型复印机为代表,充分体现出小型化技术的最新发展。复印机设计与制造的小型化技术是随着 I. Introduction In 1959, the world’s first plain paper electrophotographic copier with automatic continuous copying, the Xerox 914 copier, appeared. Since then, people have been working hard to achieve the miniaturization of copiers. The then Model 914 was a major achievement in the miniaturization of copiers because until then there had been only manual, semi-automatic bulky flat-panel machines in the world. Today, the miniaturization of photocopiers has achieved great results, represented by (?) Portable copiers and portable ultra-small photocopiers, which fully reflect the latest developments in miniaturization technology. Copier design and manufacture of miniaturization technology is with
