Chinese typewriter

Typewriters that can type Chinese characters were first invented in the early 20th century. Written Chinese is a logographic writing system, and facilitating the use of thousands of Chinese characters requires more complex engineering than for a writing system derived from the Latin alphabet, which may require only tens of glyphs. An ordinary Chinese printing office uses 6,000 Chinese characters. Chinese typewriters, and similar Japanese typewriters invented by Kyota Sugimoto, which use kanji adopted from the Chinese writing system, started to appear only in the early 20th century. There have been at least five dozen different models of Chinese typewriter, ranging from sizable mechanical models to sophisticated electric word processors.
