  • Publication number: 20230344948
    Abstract: An image reading apparatus includes a transport unit which transports a document, and reading units which read an image of the document which is transported. It is assumed that an operation of reading an image when specific setting information is not input to a control device of the image reading apparatus is set to a first reading mode, and an operation of reading an image when specific setting information is input to the control device is set to a second reading mode. In this case, in the second reading mode, image data of an image with a resolution which is equal to that in the first reading mode is generated, while causing the reading units to read an image from a document which is transported by the transport device at a lower speed than that in the first reading mode.

  • Patent number: 11787653
    Abstract: An image reading apparatus includes a feeding roller that includes a first roller and a second roller provided at an interval in a width direction intersecting a medium feeding direction, and feeds a sheet from a placing section; and a skew detection section that detects skew of the sheet fed from the feeding roller. Skew is corrected by giving a difference between a rotation speed of the first roller and a rotation speed of the second roller with respect to at least one of the relevant sheet detected by the skew detection section and subsequent sheets fed following the relevant sheet based on a skew amount in the sheet.

  • Patent number: 11438474
    Abstract: An image reading apparatus includes a support portion in contact with a mount surface on which the apparatus is mounted, an apparatus body portion that is provided so that a position thereof is changeable by being rotated relative to the support portion, and a discharge tray provided so as to be openable/closeable relative to the apparatus body portion, the discharge tray receiving the original. The apparatus body portion is switchable between a first position that is a position while not in use, and a second position in which reading of the original is performed. When the apparatus body portion is in the first position and when the discharge tray is opened from the closed state, the discharge tray switches the apparatus body portion from the first position to the second position.
