Abstract
A copying machine of the type in which an original image is formed as a visible image on a first drum and the visible image from the first drum is transferred as a secondary original image to a second drum from which multiple copies are made. A single lens system is used both to transfer the image from the original document to the first drum and transfer repeatedly the image on the first drum to the second drum thereby greatly reducing the number of optical components required in the system.
