ABSTRACT:
An optical reader comprises a plurality of light emitting elements which illuminate a plurality of points through a plurality of optical fibers, a plurality of light receiving elements which receive reflected light from the plurality of reading points through a plurality of optical fibers, and read means for reading an image on a paper on the basis of outputs from the light receiving elements. Amounts of light emitted by the individual light emitting elements are established at a plurality of halftones for illumination, thus eliminating the need for a compensation of a reference value to be used with the individual light emitting elements, thus enabling an image to be read in multiple halftones.
