ABSTRACT:
A copying machine having an original platform on which an original is placed, an original cylinder around which an original is wound, a photosensitive body on which an image of the original is formed, an original set mechanism for winding a copied paper sheet, produced from the original on the original platform, around the original cylinder, and an optical device. The optical device is provided with a rotatable exposing lamp for applying light from it to either exposure position set on the original platform or on the original cylinder, a rotatable reflecting mirror for further reflecting reflected light at the exposure position, a copying lens for refracting the reflected light on the reflecting mirror towards the photosensitive body and a mechanism for synchronously rotating the exposing lamp and the reflecting mirror, wherein the reflected light at either exposure position on the original platform or on the original cylinder is further reflected by the reflecting mirror onto the optical axis of the copying lens and refracted light through the copying lens is directed towards the photosensitive body to form the image of the original on the photosensitive body in the copying operation.
