Publication number: 20110180988Abstract: A technique in an image forming apparatus in which the front and back sides of a sheet are reversed by using a reversal conveyance path is provided for causing the sheet to wait such that the sheet is not damaged when a unit for conveying the sheet to the reversal conveyance path is pulled out for the purpose of clearing a jam or the like. A roller for conveying the sheet is controlled such that the sheet to be turned back and directed into the reversal conveyance path is caused to wait until the sheet can be conveyed into the reversal conveyance path. As a standby position of the sheet while the sheet is caused to wait, a position is set such that an upstream end portion in the second conveying direction of the sheet to be directed into the reversal conveyance path does not extend for a predetermined length or longer into another conveyance unit adjacent to the intermediate conveyance unit upstream from the intermediate conveyance unit in the second conveying direction.Type: ApplicationFiled: April 6, 2011Publication date: July 28, 2011Applicants: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventors: Masataka MURATANI, Kazumasa Yasui, Masaya Arakawa

Patent number: 7980556Abstract: An image forming apparatus has an image forming unit that forms an image on a sheet; a discharging roller pair that discharges the sheet, on which the image is formed, onto a stacking portion with a rotation in a first direction, and conveys the sheet to a re-conveying path for conveying the sheet to the image forming unit again with a rotation in a second direction opposite to the first direction; and a skew feed correction member that is provided in the re-conveying path, and contacts against a leading edge of the sheet conveyed by the rotation in the second direction to correct skew feed of the sheet. The sheet conveying force when contacting the leading edge of the sheet against the skew feed correction member is smaller than sheet conveying force of the discharging roller pair when discharging the sheet onto the stacking portion.Type: GrantFiled: April 20, 2010Date of Patent: July 19, 2011Assignee: Canon Kabushiki KaishaInventor: Tatsubumi Mizuno
