  • Image reading apparatus provided with original document skew correction function
    Patent number: 10079948
    Abstract: According to detection results of a plurality of original document detectors, an image reading apparatus determines whether or not correcting skew of an original document is possible, controls a pair of a plurality of transport rollers in a case where it is determined that correcting the skew of the original document is possible, and corrects the skew of the original document by making transporting speeds of the pair of the plurality of transport rollers different from each other.
    Type: Grant

    Date of Patent: September 18, 2018
    Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.

  • Image reading apparatus and document transport method used therefor
    Patent number: 10009495
    Abstract: There is provided an image reading apparatus that, when double feeding of documents is detected by a double feeding detector, transports the documents in the reverse direction of the transport direction at least until the leading edges of the double-fed documents are positioned at the upstream side of transport roller pairs by rotating a separation roller and a retard roller so as to transport the documents in the reverse direction, and that thereafter transports the documents in the transport direction by rotating the separation roller so as to transport the documents in the transport direction. When the documents are transported in the reverse direction, the image reading apparatus sets a second rotation speed of the retard roller to be faster than a first rotation speed of the separation roller.
