  • Patent number: 3945725
    Abstract: There is provided a copying machine which is most suitable for multiple reproduction at high speed. The copying machine of the present invention employs a flat, movable sensitive screen having a number of openings or apertures. The image of an original is once formed on the sensitive screen as an electrostatic latent image. With the use of the thus formed image on the sensitive screen, another electrostatic latent image is formed on a recording paper while the screen is stationary. The recording paper is then passed through a developing means and a fixing means provided in the copying machine and discharged out to a tray. The electrostatic latent image formed on the sensitive screen may be used repetitively for obtaining multiple reproductions.
