Claims (1)
被読取面からの反射光をレンズ系を通して集光し
、主走査方向に配置された受光センサアレイに結
像させる画像読み取り装置において、前記レンズ
系は前記主走査方向に沿つて複数配設され、各々
のレンズ系は一対の平凸レンズを凸レンズ部が向
き合うよう配置して構成されていることを特徴と
する画像読み取り装置。 The image reading device irradiates the surface to be read of the document with light from a light source, collects the reflected light from the surface to be read through a lens system, and forms an image on a light-receiving sensor array arranged in the main scanning direction. An image reading device characterized in that a plurality of lens systems are disposed along the main scanning direction, and each lens system is constructed by arranging a pair of plano-convex lenses such that the convex lens portions face each other.
