ラー複写機用光学装置。 An object is placed on one end of a bundle of convergent light transmitters having a refractive index distribution in the radial direction, and an image forming surface is disposed on the other end. In the optical device for a color copying machine, the optical device is configured to form an erect life-size real image of the object on the image forming surface by means of a beam of light transmitting material, the optical device having a thickness corresponding to each wavelength of the three primary color lights; In each pair, three pairs of transparent plates have the same thickness and at least one of the pairs also serves as a color filter, and when exposed to each of the three primary color lights, moving means for sequentially moving the transparent plates to position them at both ends of the converging light transmitting body bundle, the optical path length between the object and the image forming surface according to each wavelength of the three primary color lights. 1. An optical device for a color copying machine, characterized in that the difference in color is corrected by the three pairs of transparent plates.
