原稿照明装置。[Claims for Utility Model Registration] 1. In a document illumination device that reads a document by reflecting light from a tubular light source in the reading line direction of the document by an opposing reflector, the reflecting surface of the opposing reflector is connected to the tubular light source. What is claimed is: 1. A document illuminating device characterized in that the document illuminating device is configured to reflect illumination light near the center of the reading line toward an end of the reading line. 2. In a document illumination device that reads a document by reflecting light from a tubular light source in the reading line direction of the document by an opposing reflector, the reflecting surface of the opposing reflector is used to reflect illumination light near the center of the tubular light source. What is claimed is: 1. A document illumination device characterized in that light is divided and arranged in a sawtooth shape so as to reflect toward an end of a reading line, and the opposing reflecting plate is formed in a straight line.
