とを特徴とする原稿照明装置。[Scope of Claim for Utility Model Registration] A linear light source and a gutter-shaped gutter arranged to surround the linear light source that condenses the emitted light from the linear light source to form a belt-shaped illumination area on the surface of the document. In a document illuminating device comprising a reflecting mirror and a holder disposed on the back side of the reflecting mirror and including a reflecting mirror holding plate holding the reflecting mirror, the reflecting mirror is provided with a light beam from the illumination area to the reflecting mirror. A through hole is provided through which a part of the reflected light passes through, a projection opening is formed by cutting and raising a portion of the mirror holding plate opposite to the through hole, and the illumination area is transmitted through the projection opening and the through hole. What is claimed is: 1. A document illuminating device, characterized in that a sensor for measuring light quantity is provided at a position desired to provide light, and a cut-and-raised portion related to the projection opening is used as a light shielding plate for scattered light passing through the projection opening.
