Scanning device for microline-by-microline illumination and optically scanning a planar original

摘要

An apparatus for microline-by-microline illumination and scanning of a planar original has a number of spaced illumination elements, each having longitudinal and transverse dimensions substantially corresponding to a microline, and a number of spaced light-receiving elements disposed perpendicularly with respect to the microlines and corresponding to the number of desired picture elements along a microline to be scanned. Each light-receiving element at least partially overlaps a microline. The illumination elements and the light-receiving elements are respectively disposed in parallel planes in a common film. Structure is also provided at each overlap of a light-receiving element with a microline for coupling light from an illuminated microline to the light-receiving element.
