置。[Claims for Utility Model Registration] A document in which a document containing information to be read is illuminated with light from a light source, and the reflected light from the document surface is guided to a photoelectric conversion element array by an optical fiber array to read the information on the document surface. The optical fiber array is a reading device, and has an entrance side end surface and an exit side end surface that are parallel to each other, and the side surface is supported by a supporting glass plate, and the document illumination light is transmitted through the supporting glass plate. The incident state to the optical fiber array is determined so that the light enters the optical fiber array from the side surface thereof at an incident angle θ and exits from the end face on the incident side to illuminate the document, and the outer wall of the optical fiber in the optical fiber array The refractive index n□ of the part and the refractive index n2 of the support glass plate satisfy the relationship n□<n2, and the incident viewing angle θ is the total reflection angle θ. θ as small as possible. A document reading device characterized in that it is determined to be close to .
