Abstract
PURPOSE: To readily produce the compound eye lens device by using the block of transparent material and light-shieldable material, in the lens used for the projection system of the copying machine.
CONSTITUTION: A block 124' of transparent material such as acrylic base resin, epoxy-base resin, polycarbonate and styrene is prepared. Bar lens curved faces are then provided on the surface of the block 124' by compression-molding, after which lancings are given between bar lens pitches by cutting or laser working. Light-shield layers are formed in the lanced portions by nontransparent plates or inking to form light-shield materials. Thereby, all the lens end faces are precision-formed by compression-molding, and the compound eye lens device which is prevented of the rear light between the bar lenses by the light shield layers is produced with good volume productivity.
