PURPOSE: To take a sharp copy at high speed while precluding exposure before reading by a simple constitution by providing a primary-color irradiating means, a detachable film case, an image forming means, a fixing means, a separating means for recording paper and a photosensitive film, and a film case reverse driving means.
CONSTITUTION: Light beams of the three primary colors are emitted 3 by the rotation of a filter 73 and reflected light from a color original 2 is converged 4 to form an image on the photosensitive film 6 which moves along the outer periphery of a drum 5. The photosensitive film is wound and stored in the detachable light-shielding case 9 and supplied to the outer periphery of the drum 5 by rollers 11 and 12. The recording paper 23 supplied by rollers 21 and 22 is pressed against the photosensitive film at a position by the cooperation between the drum 5 and a roller 15 which can contact and leave the drum, thereby taking a copy. Then the film and paper are separated by a claw 24 and the paper 23 is carried out by rollers 27 and 28. Further, the case 9 is equipped with a roller 34 for rewinding and this roller is coupled with the roller 12 to evade unnecessary exposure. The device of this constitution is simplified and obtain a sharp copy image at high speed.
