Reprographic apparatus and method

Claim 1

A reprographic apparatus for color copying an original including an optical system, comprising an objective lens or lenses, for forming on a surface a light image of the original and a device for selectively enabling a right way-round image or an inverted image of such original to be produced on such surface, the device comprising a prism having an isosceles triangle cross section with the base thereof, which is adjacent to the two equal angles, positionable opposite the objective lens or lenses and a mirror having a flat reflective surface alternatively interposable in the light path after the latter has passed through the lens or lenses of the objective of the optical system, said base of the isosceles and the reflective surface of the mirror being positionable at right angles to the axis of the lens or lenses, both the mirror or the prism being interposed in the path of the light image, according to whether a right-way-round or inverted image, respectively, is desired, means for forming on said surface a latent image of said original and means for developing said latent image.
