    Abstract: A method and apparatus for performing an image forming job by maintaining a cover, which covers a scan area and has adjustable transparency, in a transparent state until a job for acquiring image data of a scan object starts in an image forming apparatus. If the job for acquiring the image data of the scan object positioned in the scan area starts, the image forming apparatus converts the cover into an opaque state and acquires the image data of the scan object. If the job for acquiring the image data of the scan object is ended, the image forming apparatus reconverts the cover into a transparent state. Therefore, efficiency of a job for acquiring image data of a scan object is improved.

  • Patent number: 9013769
    Abstract: In a conveyor of an image-reading device, a first path is defined by a path from the upper path to the lower path via the curved path. A second path is defined by a path from the upper path to the extension path. A first reading unit is disposed on the upper path and reads the first surface while the original sheet is on the upper path. A second reading unit is disposed on the upper path and reads the second surface while the original sheet is on the upper path. A third reading unit is disposed on the lower path and reads the second surface while the original sheet is on the lower path. When the reading section reads the original sheet, the conveyor conveys the original sheet through the first path or the second path.

  • Patent number: 9013764
    Abstract: In a reading apparatus, a control device is configured to: acquire a conveyance path switching information indicating whether a conveyance path switching unit has switched a conveyance path to a first conveyance path or a second conveyance path; judge, based on detection results by a width detecting unit, whether a type of an original sheet that is currently placed on an original sheet placing unit and that is not yet conveyed by a conveyance unit from the original sheet placing unit is a first type or a second type; and determine, based on both of the conveyance path switching information and the type of the not-yet-conveyed original sheet, whether the conveyance unit should stop conveyance of a preceding original sheet that the conveyance unit is currently conveying.

  • 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.
