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.

DETAILED DESCRIPTION It is an object of the present invention to provide a reading apparatus having a staggered compound-eye optical system which is inexpensive and easy to manufacture.
It is a further object of the present invention to provide an apparatus which can effect reading with a stable imaging performance without being combered by external factors such as humidity even if the compound-eye optical system is formed by a plurality of lens blocks formed of plastic.
The invention will become fully apparent from the following detailed description thereof taken in conjunction with the accompanying drawings.
