Abstract
By means of two cylinders each composed of two interconnected discs, and which cylinders are rotatable in synchronism about a common axis and respectively transport along portions of their circumference an image carrier and a copy carrier, such carriers are continuously forwardly moved at identical angular velocities. A light source projects the negative located at the image carrier through an objective arranged at the common axis upon the copy carrier. The magnification and ratio reduction ratio is proportional to the ratio of the diameters of both cylinders. The light beam which passes through a slotted diaphragm projects continuously and in a strip-shaped configuration the negative from the image carrier to the copy carrier with constant opposite sense movement of such image and copy carriers.
