Claims

[Scope of utility model registration request]

(1) Place the original in contact with one side of an optical fiber plate consisting of an optical fiber bundle and a substrate that sandwiches the optical fiber bundle from both sides so that both sides are perpendicular to the direction of the fibers, and a photoelectric converter is arranged closely to the end face of the optical fiber bundle on the surface, a light source is provided on one side of the optical fiber bundle on the photoelectric converter side of the optical fiber plate,
The light source diagonally traverses the optical fiber plate substrate and the optical fiber bundle to illuminate a document at a reading position in contact with the end of the optical fiber bundle, and the reflected light is irradiated to the photoelectric converter via the optical fiber bundle. In an image reading device configured to read an image of a document, a reflective surface of the optical fiber bundle of the optical fiber plate is brought into contact with or in close proximity to the side opposite to the light source, and the reflective surface is directed toward the optical fiber bundle. An image reading device characterized by being provided with a mirror.

(2) The image reading device according to claim 1, wherein the mirror is formed by mirror-finishing the end face of the substrate adjacent to the optical fiber bundle.
