Patent number: 8366096Abstract: A document reader has a main conveying path, an auxiliary conveying path, a pickup roller, a first conveying roller, and a second conveying roller. The auxiliary conveying path runs between a first connection point and a second connection point on the main conveying path. The cylindrical surface of the first conveying roller is located partially on the main conveying path and partially on the auxiliary conveying path. While the first conveying roller is under the forward or reverse control, it rotates normally. The cylindrical surface of the second conveying roller is located partially on the main conveying path between the second connection point and a discharge position. A controller switches from the forward control selected during this mode to the reverse control, while a document being conveyed along the main conveying path is out of contact with the first conveying roller.Type: GrantFiled: June 26, 2009Date of Patent: February 5, 2013Assignee: Sharp Kabushiki KaishaInventors: Kazuhiro Mizude, Kenji Tanaka, Hideyuki Hiro, Daisuke Mukaiyama, Tomohiko Okada

Patent number: 8107835Abstract: An abnormality detecting method and an image processing method for an image processor is provided. The image processor can easily detect an abnormal rotation of a photosensitive drum without having a special detecting means but using an existing sensor, and keeps image data until a normal toner image is transferred and fine printing is carried out. The image processor forms a toner image corresponding to image data on a plurality of photosensitive drums, and detects the position of the toner image at a given part on a transfer object, to which given part the toner image formed on the photosensitive drum is transferred, to detect a rotation failure of the photosensitive drum. When a rotation failure is detected, the image processor keeps input image data without deleting even after the end of image formation.Type: GrantFiled: August 7, 2007Date of Patent: January 31, 2012Assignee: Sharp Kabushiki KaishaInventors: Kazuhiro Mizude, Tsutomu Yoshimoto, Hiromasa Shibano
