Abstract

PURPOSE:To easily assemble a plate-like lens, by injection-molding a lens substance in one body in an opaque frame plate having holes for plural lenses, and said holes. CONSTITUTION:On a frame body 1 consisting of an opaque substance, plural holes 2 for lenses are punched at a constant pitch. On both the sides of the holes 2, grooves 3 for a lug of a lens which is injection-molded in these holes are provided, and the grooves 3 serve as a sprue runner, too. Said frame body 1 is placed between metallic molds 4 and 5 for injection-molding, and the charging is performed to cavities 6, 7 for a lens of each metallic mold through the sprue runner 8.
