摘要：
A slit illumination system including a document support, a light source, a first elliptic mirror arranged at an opposite side to the document support with respect to the light source, an auxiliary mirror positioned at an opposite side to the first elliptic mirror with respect to the image light passage reflected by the document and a second elliptic mirror arranged at the side of the document with respect to the first elliptic mirror. The first elliptic mirror has a focussing line thereof positioned above or below the document and the second elliptic mirror has it positioned at the opposite side. The illumination light which is composed from the first elliptic mirror and from the second elliptic mirror through the auxiliary mirror has a flat top illumination intensity on the document.
