Patent number: 6567187Abstract: A printing apparatus has high reliability both in manual feeding and in automatic feeding of a printing medium, and a feeding control method controls the printing apparatus. In the case of manual feeding of a sheet as the printing medium, the sheet is transported by an LF roller for an amount sufficient for feeding the tip end of the sheet to a discharge paper sensor located on the downstream side of a paper path with respect to a printing head. Judgment whether paper feeding is successful or not is made depending on whether the sheet is detected by the discharged paper sensor. On the other hand, in the case of automatic feeding using an automatic feeding apparatus, the operation of transporting the sheet to the discharged paper sensor is not performed. By this, in the case of automatic feeding, it becomes unnecessary to backwardly feed the sheet before initiation of printing so that the rotation amount of the LF roller is minimized.Type: GrantFiled: April 13, 1999Date of Patent: May 20, 2003Assignee: Canon Kabushiki KaishaInventors: Takeshi Iwasaki, Koh Hasegawa, Shinya Asano, Hiroyuki Inoue, Takashi Nojima, Akira Kida, Noriko Kawasaki

Publication number: 20010054787Abstract: A sheet conveying device includes conveying means respectively located at an upstream side and a downstream side on a sheet conveyance path. First drive means rotates the upstream conveying means at a constant speed while second drive means rotates the downstream conveying means at a variable speed. When the second drive means accelerates the rotation of the downstream conveying means, speed adjusting means causes the conveying speed of the upstream conveying means to reflect the acceleration. The sheet conveying device insures smooth, reliable conveyance even when a sheet extends over both of the upstream and downstream conveying means.Type: ApplicationFiled: March 22, 2001Publication date: December 27, 2001Applicant: Ricoh Company, Ltd.Inventor: Masaru Yamagishi

Patent number: 6308946Abstract: An image forming apparatus with a foreign material removal apparatus is formed of a sheet feeding table which is vertically movable and supports printing sheets thereon; a sheet feeding device for feeding the printing sheets stacked on-the sheet feeding table one by one; an image forming device for forming an image on the printing sheet fed by the sheet feeding means; a detecting device situated adjacent to the sheet feeding means and detecting the printing sheets fed by the sheet feeding device; and a foreign material removal device for removing foreign material covering the detecting device. The foreign material removal device includes a pump attached to the sheet feeding device and driven by vertical movements of the sheet feeding table to flow air, and a nozzle situated adjacent to the detecting device and attached to the pump. When the sheet feeding table moves vertically, the pump allows air to flow through the nozzle to remove the foreign material covering the detecting means.Type: GrantFiled: March 27, 2000Date of Patent: October 30, 2001Assignee: Riso Kagaku CorporationInventor: Takeshi Saitoh

Patent number: 6295081Abstract: A recording medium discharge apparatus includes bins for storing sheets of paper therein. The apparatus also includes level sensors for each detecting one of the bins having been filled with paper sheets. Each sensor consists of a light emitter and a light receiver, which are positioned on both sides of the associated bin. The emitter and the receiver are aligned on a line extending across the direction in which paper sheets can be discharged. This prevents paper sheets from coming into direct contact with the sensors. Even if paper sheets discharged into each bin are once taken out and then returned to it, the returned sheets do not come in contact with the associated sensor. It is therefore possible to keep the discharge of paper sheets in good condition.Type: GrantFiled: April 1, 1999Date of Patent: September 25, 2001Assignee: Brother Kogyo Kabushiki KaishaInventors: Hiroyuki Kashima, Kazumasa Makino, Kazuhiko Takagi

Publication number: 20010011793Abstract: A taking part has a taking unit that comes in contact with the piled sheets to generate a taking force and to take the sheets one by one with the taking force. A movable lever is arranged in a side of the taking unit with respect to the piled sheets, and a driving unit gives a driving force in a linear or rotational direction to the movable lever. A force controller controls the driving force given to the movable lever by the driving unit. A detecting unit detects a position of the movable lever, and a sheet supplying unit supplies the piled sheets to the taking unit. A sheet supplying unit controller controls the sheets supplying unit on the basis of the position of the movable lever detected by the detecting unit. The sheets are pressed by the lever at a preparatory step, and then the sheets are lifted and pressed to the taking unit while canceling the driving force by the lever. The sheet and the taking unit are assured to become in good contact with each other to make the taking operation stable.Type: ApplicationFiled: April 17, 2001Publication date: August 9, 2001Inventors: Takahiro Suzuki, Hiroyuki Kamiyama, Junichi Inoue

Patent number: 6206363Abstract: A catch tray attachment for a sheet feeding machine allows rapid accumulation and manual removal of a predetermined count of sheet articles from the catch tray. The catch tray itself is adapted for mounting to the frame of the sheet feeding machine so as to position it in the discharge path of sheet articles exiting the sheet feeder. Upon removal of an accumulation of sheet articles from the catch tray, a signal is sent back to the sheet feeder to initiate further machine cycles whereby a predetermined count of sheet articles are again deposited in the catch tray.Type: GrantFiled: October 28, 1999Date of Patent: March 27, 2001Assignee: Multifeeder Technology, Inc.Inventors: Arild Vedoy, Mark Nordling
