  • Focal adjustment on a single-focus lens in a continuously variable magnification system
    Patent number: 4099866
    Abstract: Method and apparatus for adjusting the position of a single-focus lens at two positions in a continuously variable reduction document copier machine. Adjustment is made at a 1:1 ratio by shifting the position of the lens on its carriage and adjusting the position of optical path mirrors until focus is obtained.
