Patent number: 7443551Abstract: A document feeder reads a document at a reading section while conveying the document. The document feeder has a flexible member which is set in a convey path formed in a document feeding section such that the document is always conveyed along the convey path, and which flexes by a passing force of the document, to allow conveyance of the document. The flexible member is formed of a PET sheet, and is adhered to a reading guide member provided to the document feeding section, to close the convey path.Type: GrantFiled: January 6, 2003Date of Patent: October 28, 2008Assignee: Konica CorporationInventors: Masashi Aoki, Tsuyoshi Mizubata, Kiyoshi Hata, Nobutaka Kato, Osamu Kato, Kazuaki Ito
