Abstract
A scanning apparatus for scanning image information of a document and generating image information has a document table for supporting a document thereon and an exposure lamp for exposing the document supported on the document table. The scanning apparatus further has a mirror for changing the direction of light reflected by the document illuminated by the exposure lamp, a rod lens array for optically converging light from the mirror, and a CCD image sensor for receiving light converged by the rod lens array and transducing the incident light to an electrical signal. The light reflected by the document is directed along the longitudinal direction of the document table. The optical axis of the rod lens is parallel to the longitudinal direction of the document table, thereby obtaining a scanning apparatus having a reduced height.
