LENS ARRAY PLATE OF ERECTING UNIT MAGNIFICATION SYSTEM, IMAGE READING APPARATUS AND IMAGE WRITING APPARATUS USING THE LENS ARRAY PLATE, AS WELL AS METHOD FOR MANUFACTURING THE LENS ARRAY PLATE

摘要

A lens array plate of long-size or large area is provided reducing deterioration of optical performance. A lengthy lens array plate (10), which is based on manufacturing process in accordance with the present invention, is formed by connecting a plurality of planar-shaped lens array plates (1) in the longer direction thereof, the planar-shaped lens array plate (1) including a plurality of lens portions that are regularly arranged. The connecting portion (3) is linearly formed at the position other than the plurality of lens portions. Thereby, a lengthy lens array plate with any length may be formed.
