Publication number: 20220009244Abstract: A print head includes a nozzle array comprising a plurality of nozzles, and a negative pressure generating portion configured to apply a negative pressure to the nozzle array. A tank includes a storage portion and an air communication port. A tube connects the print head and the tank and supply the liquid from the tank to the print head. A highest position of a liquid level in the tank in the vertical direction is higher than a position of the nozzle array, and an absolute value of a water head difference caused by a difference between the highest position of the liquid level in the tank and the position of the nozzle array is not larger than an absolute value of a negative pressure generated by the negative pressure generating portion.Type: ApplicationFiled: June 24, 2021Publication date: January 13, 2022Inventors: Hideaki Matsumura, Daiju Takeda, Tetsu Hamano, Nobuhiro Toki, Fumie Kameyama, Koki Shimada, Shota Asada, Ken Takenaga, Yusuke Tanaka, Yuta Araki, Taiji Maruyama, Atsushi Matsuyama, Yusuke Naratani, Kousuke Tanaka, Koya Iwakura

Patent number: 8807556Abstract: Even in printing apparatus that make use of a plurality of kinds of sheets, the degradation of image quality is reduced. A sheet conveying apparatus includes: a sheet stacking unit; a sheet conveying unit being in contact with the sheet stacked on an uppermost portion, of the stacked sheets, and conveying the sheet; a separation unit separating the sheets into only one sheet of the uppermost portion by a separation slope that abuts a tip portion of the sheet conveyed by the sheet conveying unit; and a guide unit connected to the separation unit and guiding the sheet, in which an angle between the sheet stacking unit and the separation slope is switched to a first angle and a second angle smaller than the first angle by a rotation center of the separation unit provided in a vicinity of a connection portion of the separation unit and the guide unit.Type: GrantFiled: June 21, 2012Date of Patent: August 19, 2014Assignee: Canon Kabushiki KaishaInventors: Noriyuki Sugiyama, Hiroyuki Saito, Atsushi Ikeda, Yasuyuki Hirai, Noriko Sato, Masashi Ito, Fumie Kameyama

Patent number: 8727526Abstract: In an inkjet printing apparatus capable of automatic duplex printing, time required to fix ink is shortened and throughput is improved without producing uneven fixing. The inkjet printing apparatus includes a printing unit that prints onto a sheet, a fixing unit that heats a sheet printed by the printing unit, a conveying unit that conveys a sheet with respect to the printing unit and the fixing unit, and a controller that controls the conveying unit such that a printing region of a sheet printed on the first side by the printing unit passes through the fixing unit, and afterwards, the conveyance direction of the sheet is reversed in order to print on the second side and the printing region once again passes through the fixing unit. The controller variably controls the conveyance speed of the sheet when the printing region once again passes through the fixing unit.Type: GrantFiled: April 20, 2011Date of Patent: May 20, 2014Assignee: Canon Kabushiki KaishaInventors: Kosuke Yamamoto, Tetsuya Saito, Yoshiaki Suzuki, Koji Furusawa, Hiroshi Tajika, Masahiko Watanabe, Atsuhiko Masuyama, Atsushi Miyahara, Masashi Ito, Fumie Kameyama

Patent number: 8506053Abstract: A recording apparatus includes a head set lever which fixes a head cartridge to a carriage section. The head set lever is movable between a first position at which the head cartridge is fixed to the carriage section and a second position at which mounting and removal of the head cartridge on and from the carriage section is permitted. Attachment of an ink tank to the head cartridge is inhibited when the head cartridge is mounted on the carriage section and the head set lever is arranged at a position other than the first position.Type: GrantFiled: March 20, 2012Date of Patent: August 13, 2013Assignee: Canon Kabushiki KaishaInventors: Fumie Kameyama, Motoyuki Taguchi, Akira Kida, Nozomu Nishiberi, Noriyuki Sugiyama, Masayuki Imano
