Publication number: 20130010043Abstract: In a first step, a sheet is conveyed in a direction, whereby a leading end portion of the sheet is fed to a position between a decurl roller and a decurl pinch roller, which are in positions spaced apart from each other. In a second step, the leading end portion of the sheet is curved and held by causing the decurl pinch roller to come close to or press against the decurl roller. In a third step, the leading end portion of the sheet is withdrawn from between the decurl roller and the decurl pinch roller by conveying the sheet in a direction opposed to the conveying direction. After executing the first to third steps, the sheet is conveyed in the conveying direction through the first step while the sheet is curved by the decurl roller.Type: ApplicationFiled: September 14, 2012Publication date: January 10, 2013Applicant: CANON KABUSHIKI KAISHAInventors: Masahito Yoshida, Yasuhiko Ikeda, Kenji Shigeno, Koichiro Kawaguchi, Toshiki Takeuchi, Masato Izumi, Kengo Nieda, Ryosuke Sato

Publication number: 20110211030Abstract: An apparatus for performing duplex printing having a sheet feeding unit, a printing unit, a cutter unit, a drying unit, and a reverse unit. In the duplex printing, the printing unit prints a plurality of images on a first surface of a sheet fed from the sheet feeding unit. The sheet is a continuous sheet. The sheet printed on the first surface passes through the drying unit and is led to the reverse unit. The reverse unit feeds the reversed sheet to the printing unit and the printing unit prints a plurality of images on a second surface that is a back of the first surface of the sheet fed from the reverse unit. The cutter unit cuts the sheet printed on the second surface into a plurality of cut sheets each having the image printed thereon. The cut sheets pass through the drying unit and are ejected.Type: ApplicationFiled: November 18, 2010Publication date: September 1, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Tetsuhiro Nitta, Yasuhiko Ikeda, Masahito Yoshida, Kota Uchida

Publication number: 20110135372Abstract: A both-side recording apparatus that enables both-side recording on continuous paper using a single recording head, without cutting the continuous paper at an intermediate position, is provided. Reduction in size and costs of the apparatus is achieved by eliminating a conveying path dedicated to both-side recording. The apparatus includes a paper-feeder that feeds continuous paper, a recording head that records an image on the continuous paper, a reversing unit that reverses the continuous paper such that a recording surface of the continuous paper facing the recording head is reversed, and a rewinding mechanism that rewinds the fed continuous paper to the paper-feeder. During both-side recording, recording is performed on the back side of the continuous paper by rewinding the continuous paper by the rewinding mechanism, setting the back side of the continuous paper to oppose the recording head by the reversing unit, and feeding the continuous paper from the paper-feeder.Type: ApplicationFiled: November 17, 2010Publication date: June 9, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Ryosuke Sato, Yasuhiko Ikeda, Masahito Yoshida, Koichiro Kawaguchi, Kenji Shigeno, Toshiki Takeuchi, Masato Izumi, Kengo Nieda
