Abstract: PURPOSE:To form the photo pictures into images by using a means which synthesizes extracted R, G and B beams into a focusing beam and performs the main scan on a photosensitive matter for exposure and a means which performs the relative secondary scan to the photosensitive matter. CONSTITUTION:The R, G and B components which are slowly gathered by a lens 11 and passed through a filter 12 are extracted by an optical shutter as color signals. The parallel luminous fluxes of optical fibers 14 enter the mirror boxes 16 respectively and condensed by a lens 17. Then a 3-color synthetic light passed through the lens 17 hits a polygon mirror 18 to undergo the optical scan with rotations of the mirror 18 driven by a motor and made incident on a photosensitive matter which is formed into an image through a spherical lens. Then the luminous fluxes are reflected by the mirror 18 with the movement of an optical system including a light source 8, etc. These reflected luminous fluxes perform the main scan on a film and at the same time undergo the secondary scan with movement of a base plate. Thus the entire surface of the film is exposed and the photo pictures can be formed into images.
