Abstract
A copying machine using a slide projector, in which the slide projector is situated such that its light path does not coincide with that of the optical device so as to secure a smooth circulation of cooling air through the copying machine. The lack of coincidence of the optical paths is compensated by adjusting the position of a photosensitive sheet with respect to that of an exposure plate so as to effect the reliable formation of an image whether light is reflected from a document placed on a document table or projected through a slidefilm by a slide projector.
