PURPOSE:To secure the necessary length of an optical path of an optical system, to simplify a mechanism and to minimize a device by forming images on a copying sensitive body with the mirror for scanning of a photographing optical system which scans an original picture to form an image on a film. CONSTITUTION:Original information is photographed by scanning an original 24 which moves in a direction A with a light source 38 and a mirror 40 and exposing an electrophotography film 30 with a fixed mirror 44 shown with an alternate long and two short dashes line, a fixed mirror 50 and moving mirrors 46 and 48 through a lens 52. In a copying stage, the image of the film 30 is radiated with a light source 56 and the sensitive body 76 is exposed to be copied with a lens 81 through the lens 52, the mirrors 50, 48 and 46 and the mirror 44 shown with a continuous line, which rotates clockwise. Then, by means of the scanning mirror of the photographing optical system, the photographed image is scanned to form the image on the sensitive body at the time of copying and the length of the optical path of the copying optical system can be secured, and also the mechanism can be simplified and minimized.
