  • Patent number: 10931843
    Abstract: A multi feed detection device includes a position detector that detects a position of paper being transported, a multi feed detector that is disposed on a downstream side of the position detector in a paper transport direction and detects multi feed of the paper being transported, and a control section that performs control such that multi feed detection by the multi feed detector is stopped when a leading end of paper being transported next to paper, on which multi feed detection is executed by the multi feed detector, is detected by the position detector.
    Type: Grant
    Filed: April 9, 2019
    Date of Patent: February 23, 2021

  • Patent number: 9197775
    Abstract: An image reading device includes: a placement stage on which document sheets bearing respective images are placed; a pair of guide members that hold the document sheets placed on the placement stage between them and guide a document sheet when it is conveyed, at least one of the pair of guide members being movable in a width direction that is perpendicular to a conveying direction of the document sheets placed on the placement stage; an interval-between-guide-members detecting unit that detects an interval between the pair of guide members; a document sheet conveying unit that conveys the document sheets placed on the placement stage sequentially one by one and thereby causes the document sheets to pass a reading position; a document reading unit as defined herein; a first inclination correction unit as defined herein; and a correction mode switching control unit as defined herein.
