Claims (1)
台上に載置された原稿の像を感光体に露光するべ
く該原稿に光を投射する原稿照明装置であり、 棒状の光源と、 原稿載置台側に開口部を有し、該光源の光が該
開口部を通つて原稿載置台側へ投射されるように
該光源を長手方向に沿つて取り囲む反射鏡と、 該反射鏡の開口部を通過する光源の光量を規制
するべく該開口部の一部を覆う調光板と、 前記反射鏡にて取り囲まれた部分へ気流を流入
させるべく該調光板に開設された気流流入口と、 該気流流入口へ気流を案内するべく該調光板に
配設されたガイド板と、 を具備する原稿照明装置。[Scope of Claim for Utility Model Registration] A document illumination device that projects light onto a document placed on a document table while moving along the document table in order to expose the image of the document to a photoreceptor. a rod-shaped light source; and a reflecting mirror that has an opening on the side of the document table and surrounds the light source in the longitudinal direction so that the light from the light source passes through the opening and is projected to the side of the document table. a light control plate that covers a portion of the opening to regulate the amount of light from the light source passing through the opening of the reflecting mirror; and a light control plate that allows airflow to flow into the area surrounded by the reflecting mirror. A document illumination device comprising: an airflow inlet opened at the airflow inlet; and a guide plate disposed on the light control plate to guide the airflow to the airflow inlet.
