  • Patent number: 4464046
    Abstract: In a copying machine having an optical system for directing an image from a microfilm onto a photosensitive drum either of two fixed focus projecting lenses may be moved into alignment with the microfilm. Each projecting lens is provided with an adjustable drive system for moving the projecting lens along the optical axis thereof to vary the magnification. A plurality of mirrors are provided for reflecting the image received from said projecting lens onto the photosensitive drum. Two of the mirrors are supported at right angles to each other on a support member for reflecting an incident beam of light on one of the mirrors in a direction opposite and parallel to the incident light beam. A drive system is provided for moving the support member parallel to the incident light beam for varying the length of the optical path.
