ABSTRACT:
The invention comprises an improvement to a compact copying apparatus of a slit exposure scanning type. A plurality of sheets of plastic lens elements provide an array of optical erecting lens systems that combine to provide overlapping images of an original on an image recording member. The optical system is designed to comply with predetermined parameters of distance between the original and the image recording planes, the magnification of the inverted real image, the maximum effective aperture of the lens system, and the distance between respective edges of maximum effective apertures of adjacent lens systems.
