PURPOSE:To miniaturize the apparatus entitled above and reduce the copying time considerably by attaching 3 pair of erect real image optical system consisting of 3 lens units and 3 pair of sensitive elements and forming a color-decomposed tonor image in every sensitive element. CONSTITUTION:Lens units L1, L2 and L3 in which plural lenses are arranged over the whole width of an original are arranged on the same optical axis and the 1st erect real image optical system is installed to form an image Z1 through blue light by the optical system and a dichroic filter mirror DM1 penetrating blue light. By the optical systems with the same constitution, images Z2 and Z3 through green and red lights are formed. When sensitive elements 5b-5r are shifted synchronously with the scanning of the original, a color-decomposed latent image is formed in every sensitive element and the image is developed and fixed timingly on a transfer paper S by the standard method. Thus, the apparatus can be miniaturized because lenses with short focusing are used and the copying time is sharply reduced because a color picture is obtained only by one passing of a transfer paper. |
