  • Erasing typewriter with automatic/manual selection
    Patent number: 4374626
    Abstract: An automatic erasing typewriter determines, in response to actuation of an erase key, if automatic erasing is possible. If not, the typewriter terminates the erase cycle with a backspace and conditions the typewriter for manual erase. Actuation of a character key as the next actuated key completes the manual erase. Actuation of a key other than a character key deconditions the manual erase.
