Publication number: 20130307894Abstract: A recording apparatus includes a roller and a control device. The roller is configured and arranged to convey a recording medium. The control device is configured and arranged to set a pressure load of the roller contacting with the recording medium. The control device is configured and arranged to set the pressure load of the roller to a first pressure load when the recording medium is conveyed, and to set the pressure load of the roller to a second pressure load which is lower than the first pressure load when the recording medium is not conveyed while the roller is in contact with the recording medium.Type: ApplicationFiled: July 25, 2013Publication date: November 21, 2013Applicant: SEIKO EPSON CORPORATIONInventors: Norihiro YAMASHITA, Hideo MIKURIYA

Patent number: 8016502Abstract: A cutter device includes a medium supporting surface that supports a recording medium being transported, and a cutter carriage that has a cutter blade for cutting the recording medium and that is movable in a direction perpendicular to the transport direction of the recording medium. An opening that forms a passage region for the cutter carriage is provided in the medium supporting surface so as to extend in the moving direction of the cutter carriage. The opening is provided with a cover capable of switching between a first state in which the cover covers the opening and forms part of the medium supporting surface and a second state in which the cover is retracted to form the passage region for the cutter carriage.Type: GrantFiled: January 29, 2009Date of Patent: September 13, 2011Assignee: Seiko Epson CorporationInventors: Shoji Akatsu, Eiji Kumai, Norihiro Yamashita, Yuta Tsukada

Patent number: 7182336Abstract: A paper feed unit includes a hopper on which sheets are stacked and which is turned around a rotation shaft. The hopper is turned to move apart from or move to a paper feed roller. The paper feed unit has three modes: a large release mode in which the hopper is turned to be most apart from the paper feed roller, a non-release mode in which the printing sheet is abutted against the paper feed roller, and a small release mode in which the printing sheet is slightly separated from the paper feed roller, and is at a medium level between the above two modes. When a paper feeding job is still present, a state that the uppermost printing sheet is slightly separated from the paper feed roller is retained by the small release mode, whereby a swing range of the hopper is minimized.Type: GrantFiled: November 4, 2004Date of Patent: February 27, 2007Assignee: Seiko Epson CorporationInventors: Toru Fukushima, Kazuhisa Kawakami, Masafumi Furuyama, Yoji Sasai, Norihiro Yamashita, Yoichi Kobayashi, Hirotomo Tanaka

Patent number: 6561611Abstract: Recording paper fed from a paper feed section comes in contact with a paper detection member of a detector unit and the paper detection member is rotated about a first fulcrum, shading the optical axis of an optical sensor. When the recording paper passes through and the paper detection member is brought out of contact with the recording paper, the paper detection member is restored to the former position and does not shade the optical axis. A carriage/cartridge detection member of the detector unit comes in contact with a carriage engagement part and a cartridge engagement part placed in a carriage and is rotated about a second fulcrum, shading the optical axis of the optical sensor. When the carriage/cartridge detection member is brought out of contact with the engagement parts, the carriage/cartridge detection member is restored to the former position and does not shade the optical axis.Type: GrantFiled: December 6, 2000Date of Patent: May 13, 2003Assignee: Seiko Epson Corp.Inventors: Yoichi Kobayashi, Kazuhisa Takeda, Norihiro Yamashita, Mamoru Ukita, Kazuo Otsuka, Norihiko Kurashima

Publication number: 20010012026Abstract: Recording paper fed from a paper feed section comes in contact with a paper detection member 12 of a detector unit 8 and is rotated about a first fulcrum 35, shading the optical axis of an optical sensor 16. On the other hand, when the recording paper passes through and the paper detection member 12 is brought out of contact with the recording paper, the paper detection member 12 is restored to the former position by the urging force of an spring 37 and does not shade the optical axis. A carriage/cartridge detection member 15 of the detector unit 8 comes in contact with a carriage engagement part and a cartridge engagement part placed in a carriage and is rotated about a second fulcrum 43, shading the optical axis of the optical sensor 16. On the other hand, when the carriage/cartridge detection member 15 is brought out of contact with the engagement parts, the carriage/cartridge detection member 15 is restored to the former position by the urging force of an spring 44 and does not shade the optical axis.Type: ApplicationFiled: December 6, 2000Publication date: August 9, 2001Inventors: Yoichi Kobayashi, Kazuhisa Takeda, Norihiro Yamashita, Mamoru Ukita, Kazuo Otsuka, Norihiko Kurashima
