Abstract
A light source illuminates a manuscript, and a light from the manuscript enters a prism block through a slit. The prism block has two pairs of parallel reflective planes which are different in length, and a light from an incident plane is reflected at least once on each reflective plane and exits an outgoing plane. The light from the outgoing plane is conducted to a CCD via a lens so as to read information about an image on the manuscript.
