ABSTRACT:
An image information reading apparatus comprises a glass plate for supporting an original sheet, a light source unit for illuminating an original sheet placed on the glass plate, a scanner adapted to read image information from the original sheet upon receiving a transmitted light beam from the original sheet, and a drive mechanism for moving the scanner along the original sheet. The light source unit includes a planar light source which is wide enough to substantially uniformly illuminate the whole region of the original sheet to be read by means of the scanner.
