Patent number: 11122177Abstract: An image reading device reads two types of documents, a first document having a first size and a second document having a second size larger than the first size. A controller of the device causes the first document reader to read the first document and generate image data when the operation unit accepts a command. The first document reader reads a portion of the second document and generates image data on tilt of the second document when the operation unit accepts a command. The document tilt detector detects tilt of the second document based on the image data for detecting tilt of the second document. The document transporter stops transport of the second document when the document tilt detector detects tilt of the second document. The second document reader reads the second document and generates image data when the document tilt detector detects no tilt of the second document.Type: GrantFiled: July 17, 2020Date of Patent: September 14, 2021Assignee: SHARP KABUSHIKI KAISHAInventors: Noritomo Nakashima, Makoto Higuchi

Patent number: 8446648Abstract: In one embodiment, an image reading apparatus has a light source configured with a plurality of light-emitting elements disposed in a row in a main scanning direction that irradiate light toward an original, and a photoelectric conversion element that receives light reflected from the original, an output light amount from the light-emitting elements can be adjusted, and a state of bright spots due to repetition of light-dark in the main scanning direction on a light irradiation face of the original due to the plurality of light-emitting elements is determined, and the output light amount from the light-emitting elements is adjusted based on the determination result of the state of the bright spots.Type: GrantFiled: November 1, 2010Date of Patent: May 21, 2013Assignee: Sharp Kabushiki KaishaInventor: Noritomo Nakashima

Patent number: 8228568Abstract: The document read apparatus according to the present invention has a light source unit that includes a linear first light and second light sources, both light sources aligned parallel to the sub scanning direction (moving direction). When the light source unit is scanning a book document in a second region shifted toward a side of the first light source from a center position for emitting light to the center of the document, a light quantity of the second light source becomes larger than a light quantity of the first light source. When the light source unit is scanning the book document in a third region shifted toward a side of the second light source from the center position, the light quantity of the first light source becomes larger than the light quantity of the second light source. A sum of both light quantities is controlled to be constant.Type: GrantFiled: May 20, 2009Date of Patent: July 24, 2012Assignee: Sharp Kabushiki KaishaInventors: Mitsuharu Yoshimoto, Yasuhiro Suto, Tomohiko Okada, Noritomo Nakashima, Kenji Tanaka, Shohichi Fukutome

Patent number: 6975435Abstract: In the correction of the quantity of light of a light source used in an image reader which irradiates an original document with the light source, receives the reflected light by a CCD and reads the original document image, at the time of a document moving mode in which the document moves, correction of the quantity of irradiation light of the light source is performed by reading a first standard white board which extends over the whole area in the main scanning direction, prior to the initiation of readout of the moving document, and upon initiation of readout of the moving document, a second standard white board arranged outside the document passing area is read by using the same light source, with the read operation of the moving document, and correction of the quantity of irradiation light of the light source is performed based on the reflected light from the second white board.Type: GrantFiled: February 23, 2000Date of Patent: December 13, 2005Assignee: Sharp Kabushiki KaishaInventors: Yoshifumi Maitani, Michiyuki Suzuki, Michiaki Nishimura, Kazuya Masuda, Noritomo Nakashima, Takehiro Kato
