There is disclosed a document reading apparatus for use in a facsimile system capable of always keeping the surface of a reading base plate, mounted on the top surface of a document conveying device, clean so that the quality of an image signal read out from a document is highly improved. The improved device is achieved by preventing said reading base plate from making direct contact with a document being conveyed, so that a light beam irradiated from a light source can be properly and efficiently reflected. The inventive subject including a light source 1, reflectors 3 and 3', a lens 4, and a light-electricity converting means 5 includes a reading base surface which is protruded a little more than a reading base plate and protrusion means which is formed in proximity to a document inlet.
