Abstract
PURPOSE:To achieve the copying of both originals with one set of copying machine, by providing two optical paths and projecting a microfilm and a document original to the same reading means in respective paths. CONSTITUTION:In copying a document original, a mirror 22 is located on the 1st optical path and intercepts the 1st optical path, then the image of the document original is projected and copied on a photosensitive drum 6 in the same manner as normal copying machines and with unmagnification and variable magnification. On the other hand, in copying a microfilm. the entire mirror 22 is moved to the outside of the 1st optical path and the microfilm can be copied on the photosensitive drum 6 through magnified projection in the same manner as a microfilm printer. In the case, the document original can not be removed from a mounting stand 23.
