The first typewriter (打字机), with a keyboard which looked like a piano, was invented in the late 19th century.

Most typists ended up breaking the typewriter altogether when separating the keys. (3)______ DIt turned out to be a great success. It placed keys in such a way that the most used letters were spaced out so that the keys were more likely to work freely.
