Patent number: 8059314Abstract: An image reading apparatus which is capable of performing a stable reading operation and matching a sub-scanning magnification with which an original image is scanned, between the front side of an original and the reverse side of the same. A CCD line sensor reads the front side of an original, and a CIS line sensor reads the reverse side of the same. A lead roller is disposed upstream of the CCD line sensor and conveys the original at a first conveying speed. A discharge roller is disposed downstream of the CCD line sensor and conveys the original at a second conveying speed which is higher than the first conveying speed. A CPU controls one main scanning time period of the CCD line sensor after the original is held by the discharge roller, such that the one main scanning time period becomes shorter than before the original is held by the discharge roller.Type: GrantFiled: September 20, 2007Date of Patent: November 15, 2011Assignee: Canon Kabushiki KaishaInventor: Katsuhiro Ishido

Patent number: 8055179Abstract: An image forming apparatus capable of efficiently performing an image forming processing even in a case where a post-processing apparatus performs a post-processing during a both-sides printing. A first time period needed by a first both-sides image forming processing and a second time period needed by a second both-sides image forming processing are computed in a case where a post-processing unit performs a post-processing on a recording sheet formed images on both sides thereof. The first time period and the second time period is compared, and any one of the first both-sides image forming processing and the second both-sides image forming processing is selected based on the comparison.Type: GrantFiled: November 19, 2008Date of Patent: November 8, 2011Assignee: Canon Kabushiki KaishaInventors: Hidenori Sunada, Kiyoshi Okamoto, Mitsuhiko Sato, Yuichiro Maeda, Kiyoharu Kakomura

Publication number: 20110236096Abstract: An image forming apparatus includes an apparatus body, an image forming unit, and a retransporting unit. The retransporting unit includes a transporting roller for applying a transporting force to the sheet and an input portion disposed at a position shifted upstream of the transporting roller in a retransporting direction. The input portion is configured to receive an input of a drive force supplied from the apparatus body. The retransporting unit further includes a drive shaft extending in a retransporting direction. The drive shaft is configured to transmit the drive force from the input portion toward the transporting roller by rotating about an axis thereof. A height of the image forming apparatus may be reduced by this configuration.Type: ApplicationFiled: March 22, 2011Publication date: September 29, 2011Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Atsushi MIWA
