  • Patent number: 9106783
    Abstract: An image reading apparatus includes a light emitting diode (LED), a carriage, light receiving elements, a clamp circuit, an A/D convertor, and an image correction unit. The image correction unit is configured to: detect a document area where the reflected light is abnormal by comparing first image data with second image data; and replace the first image data corresponding to the abnormal document area with third image data. The first image data is generated by movement of the carriage in a sub-scanning direction of a first direction. The second image data is generated by movement of the carriage in the sub-scanning direction of a second direction at a reduced luminescence level of the capturing light illuminated on the document compared with a luminescence level in the movement of the carriage in the first direction. The third image data is the second image data where at least brightness is adjusted.

  • Patent number: 9041984
    Abstract: An image reading device includes a light source, an imaging section, and a controller. The light source includes a plurality of light emitting elements. The light source irradiates light to an original document, while moving relative to the original document. The imaging section obtains scan data read from the original document by light irradiated to the original document from the light source. The controller controls the light source and the imaging section. The controller determines a read target region and a non-read target region in the original document, turns on a light emitting element out of the plurality of light emitting elements, which corresponds to the read target region, and turns off a light emitting element out of the plurality of light emitting elements, which corresponds to the non-read target region.

  • Patent number: 9007661
    Abstract: In an image reading device, a movable part provided below a document platen in a housing is moved in a sub scanning direction. A reflection control part extending along a movement range of the movable part is fixed to the housing near the movable part. The reflection control part has first reflection parts having a relatively large reflectance and second reflection parts having a relatively small reflectance arranged along the movement range. A detection light irradiation part provided in the movable part irradiates the reflection control part with detection light. A detection light reception part receives the detection light reflected by the reflection control part. A signal generating part generates a binary signal corresponding to the detection light received by the detection light reception part. A movement deciding part decides movement state of the movable part according to the binary signal generated by the signal generating part.
