  • Patent number: 3990565
    Abstract: A new design of typewriter in which the keyboard is divided into two components, and which are adjustably movable away from the remainder of the typewriter, so that they may be positioned on either sides of papers placed directly in front of a typist, and from which she is copying text to be typed, each divided keyboard being operated by one of the typist's hands, and the typewriter including any one of various methods to magnify the text that is typed upon a paper so that the typist, some distance away from the typewriter clearly sees the same as typed, without straining her eyes.
