Patent number: 11736635Abstract: 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.Type: GrantFiled: April 4, 2022Date of Patent: August 22, 2023Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Mamoru Namba, Tadanobu Chikamoto, Genki Hoshino, Hiroshi Shiomi, Takashi Ohama
