  • Patent number: 8643914
    Abstract: A first light intensity curve is defined as a relationship between a first light intensity and a distance from a first reading unit. The first light intensity represents intensity of light that is part of a reflected light reflected off a first irradiated subject positioned at a distance from the first reading unit and is received by a first light-receiving unit. The first light intensity curve has a first intensity value at a first distance and a second intensity value at a second distance. The first intensity value is equivalent to the second intensity value. The first distance is different from the second distance. A distance between the first reading unit and a first read position is set to the first distance. A distance between the first reading unit and a first reference member is set to the second distance.

  • Patent number: 8587840
    Abstract: An image reading apparatus may include a cable for connecting a reading device to a controller configured to perform functions and execute instructions. To prevent breakage and stress on the cable, the cable may be fixed to a guide component. For example, the cable may be fixed to the guide component on a first side and be held by the component such that the cable includes a generally U-shaped slacked portion. According to one or more arrangements, the guide component may include an escape portion that allows for the movement of an openable unit of the image reading apparatus. In yet other aspects, the guide component may be attachable/detachable from a main body of the image reading apparatus.

  • Patent number: 8582184
    Abstract: An image reader and document conveying method shorten times necessary for a discharge process that discharges a document in being conveyed and for an idle feeding process of a document that is left on a paper feed tray. If during double-sided reading, a stop key is operated to issue an instruction to cancel reading, a conveyance controller outputs a path specifying signal to select a single-sided path, and thereby a conveyance route is switched from a double-sided path to the single-sided path. For this reason, the discharge process that discharges a document being conveyed at the time of the reading cancellation to a paper discharge tray, and the idle feeding process that discharges a document left on a paper feed tray to the paper discharge tray are performed with use of the single-sided path that is shorter than the double-sided path, and therefore the times necessary for the discharge and idle feeding processes can be shortened.
