Abstract: 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.

Abstract: A mounting device for mounting optical components within a nonmechanical printer including a pair of parallel guide rails having end portions received in attachment plates which are easily attachable to the printer frame. Mounting members are attachable to the guide rails pivotable about one of the guide rails and movable axially the guide rails. Optical component assemblies are attachable to the mounting members and movable transversely thereof.
