ABSTRACT:
An original is first illuminated with a light beam of white color or a wavelength adapted for reading of the original, and an optical image of the original is focused on a photosensitive drum previously charged uniformly, to form an electrostatic latent image on the photosensitive drum. Thereafter, the photosensitive drum is scanned with a laser beam, and a discharge current attendant on the scanning is detected and converted into an electric signal representative of the optical image. Thus, a monochromatic laser can read graphic records of any color.
