PURPOSE:To readily produce the lens device by packing and setting transparent bodies in the through-hole groups of a lens support and forming bar lens faces, with respect to the lens used for the projection system of the copying machine. CONSTITUTION:A lens support 121 which is formed of non-transparent and uniform material such as metals and is opened with through-holes in the disposition positions of bar lenses is prepared. Fluid body of transparent bodies 122 such as of acrylic resins, epoxy-base resins, polycarbonate or styrene is packed in the through- holes of the lens support 121 and is covered on its surfaces, and is then allowed to set. Thence, the lens end face groups are compression-molded on the top and bottom surfaces of the transparent body 123 thus formed, by using the dies 120, 120' having the concave spherical faces of the curvatures of the 1st, 2nd end faces of the bar lenses in the disposition positions of the bar lenses. Thereby, the compound eye lens device is produced with good volume productivity. |
