  • Patent number: 11736635
    Abstract: A reading apparatus, having a platen glass, a document cover, a conveyer, a reading sensor, a document supporting member, a pressing plate, and a linkage assembly, is provided. The document cover is movable between an open position and a closed position. The document supporting member is movable between a first position, where the document supporting member faces a reading surface of the reading sensor, and a second position, where the document supporting member is separated from the reading surface. The pressing plate is movable between a third position, where the pressing plate is attached to a lower side of the document cover, and a fourth position, where the pressing plate is removed from the lower side. The linkage assembly moves the document supporting member from the first position to the second position in conjunction with the pressing member moving from the third position to the fourth position.

  • Publication number: 20220329708
    Abstract: A reading apparatus, having a document tray, an ejection tray, a conveyer path connecting the document tray and the ejection tray and having a curved section, a conveyer to convey an original document in a conveying orientation, a first reading sensor, and a second reading sensor, is provided. The first reading sensor is located upstream in the conveying orientation from the curved section in the conveyer path. The first reading sensor optically reads a first side of the original document from below. The second reading sensor is located upstream in the conveying orientation from the first reading sensor in the conveyer path. The second reading sensor optically reads a second side of the original document from below. The first side and the second side are sides of the original document that face upward and downward, respectively, in the state where an original document is placed on the document tray.
