发明名称 正立等倍レンズアレイプレート、光走査ユニット、画像読取装置および画像書込装置
摘要 <p>An erecting equal-magnification lens array plate includes: a first lens array plate provided with a plurality of first lenses arranged on a first surface and a plurality of second lenses arranged on a second surface; and a second lens array plate provided with a plurality of third lenses arranged on a third surface and a plurality of fourth lenses arranged on a fourth surface. The first and second lens array plates are stacked. An intermediate light-shielding member provided with a plurality of intermediate through holes is between the first lens array plate and the second lens array plate. The intermediate through hole is formed such that the hole diameter is progressively smaller in a tapered fashion away from the second surface toward the third surface. A plurality of V grooves are formed in an area between adjacent second lenses on the second surface.</p>
