ABSTRACT:
This specification discloses a reading apparatus having a staggeredly arranged compound-eye optical system for divisionally forming the image of an original with respect to individual ones of a plurality of image pick-up elements juxtaposed in the primary scanning direction of the original. The compound-eye optical system comprises a plurality of lens blocks arranged in a row corresponding to said primary scanning direction, each of the lens blocks being formed with a plurality of staggeredly arranged effective plastic lens portions and a protective portion provided around and formed integrally with the effective lens portions. The boundary surface of adjacent ones of the lens blocks is inclined with respect to a plane perpendicular to the arrangement direction of the blocks so that the distance between the effective plastic lens portions and the boundary surface is greater.
