ABSTRACT:
First and second fixed light sources each comprising a lamp and an elliptical reflector radiate light onto first and second plane mirrors which reflect the light onto an original document. A drive means rotates the first and second reflectors in an interlocked manner such that the reflected light therefrom scanningly sweeps across the document in superimposed relation. The axes of the elliptical reflector are arranged so that the edges of the document are illuminated with greater intensity than the center thereof.
