Abstract

Image processing device for transparent source documents, particularly transparencies, negatives and the like, comprising an opto-electrical receiving device the output image signals of which are used for producing an electrostatic copy or for a different image processing step, an enlarging device being arranged above the receiving device in such a manner that its optical axis is aligned largely perpendicularly to the opto-electrical receiving plane and such that a matted light-transparent disc or film is provided between the enlarging device and the scanning device.
