International ClassH04N 1/04AbstractAn image reading device includes light-emitting diode chips (11A-11C) and a light guide (3) having a main region (3A) and a subsidiary region (3B). The subsidiary region (3B) includes a light incident surface (31) located above the light source (11A-11C) and an inclined surface (32). The light source (11A-11C) is offset in a direction receding from the main region (3A) with respect to the center (C2) as viewed in the primary scanning direction of the light incident surface (31).Field of SearchFiber optics or optical waveguidesFacsimile illumination control Illumination Charge coupled device Solid state With color filters Solid-state With plural sensors Scanning Scanning Light conductor Optical or pre-photocell system With imaging Plural photosensitive image detecting element arrays Optical waveguide LIGHT FIBER, ROD, OR PIPE Light source Modifier (e.g., reflector, filter) | |
