Patent number: 8162461Abstract: A printer includes a set cover pivotally movably provided on a carriage. The cover can be set in a closed state in which the cover presses a head of the cartridge housed in the housing portion and an open state in which the cover opens the housing portion when the cartridge is replaced. A release lever is subjected to a bias force so as to protrude from an inner wall surface of the housing portion. The release lever is movable against the bias force. The release lever comes into contact with an end of the cartridge which faces the bottom surface when the cartridge is inserted into the housing portion. The release lever contacts the rear surface of the cartridge housed in the housing portion. The bias force is stronger when the cover is in the open state than when the cover is in the closed state.Type: GrantFiled: April 27, 2009Date of Patent: April 24, 2012Assignee: Canon Kabushiki KaishaInventors: Naohiro Iwata, Hiroyuki Kinoshita, Hideyuki Terashima, Akihiro Tomoda, Ryosuke Sato, Kosuke Yamamoto

Patent number: 8162451Abstract: A pressure buffer is disposed in an ink supply path that connects an ink supply source to an ink-jet head to suppress pressure fluctuations due to vibrations created by movement of a carriage. The pressure buffer includes a chamber having an ink flow inlet through which ink flows from the ink supply source into the chamber and an ink flow outlet through which the ink flows from the chamber to the ink-jet head. A partition wall disposed within the chamber extends at least partly along a side wall of the chamber to define an ink flow path that communicates at its upper end with the chamber and at its lower end with the ink flow outlet. A through-opening is provided in the partition wall in the vicinity of the ink flow outlet and through which the ink flows between the ink flow path and the chamber to suppress pressure fluctuations in the ink flow path. Alternatively, an air pocket may be provided in the partition wall in the vicinity of the ink flow outlet to reduce presure fluctuations in the ink flow path.Type: GrantFiled: October 4, 2007Date of Patent: April 24, 2012Assignee: SII Printek Inc.Inventors: Yukihiro Saga, Toshiaki Watanabe

Patent number: 8162460Abstract: An inkjet printing cartridge capable of ejecting miniaturized ink droplets in a stable manner while avoiding the complexity of the structure and control as well as suppressing the cost rise. For this purpose, the inkjet printing cartridge is formed of a material having the permeability to liquid and gas, and the ink supply path for supplying ink to the ejection opening having a relatively small ejection amount is arranged adjacent to other ink supply paths via walls.Type: GrantFiled: April 9, 2008Date of Patent: April 24, 2012Assignee: Canon Kabushiki KaishaInventors: Hiromasa Amma, Keiichiro Tsukuda

Patent number: 8157364Abstract: An ink cartridge includes a case having an ink chamber for storing ink, and a face that faces an exterior of the case and has a first opening formed therethrough, and a wall comprising a chamber formed therein. The wall extends from a portion of the face, and the portion surrounds the first opening. The wall supplies ink from the ink chamber to the exterior of the case via the chamber. The ink cartridge also has a cap having a second opening formed therethrough. The cap has an inner surface covering an outer surface of the wall, and a groove formed in the inner surface of the cap and extending to the second opening. The chamber is in fluid communication with the exterior of the case via the second opening.Type: GrantFiled: December 1, 2008Date of Patent: April 17, 2012Assignee: Brother Kogyo Kabushiki KaishaInventor: Toyonori Sasaki

Patent number: 8147048Abstract: A cartridge is constituted by a plurality of absorbing materials for retaining liquid, an interface formed by press-contact between opposing surfaces of the absorbing materials, an introducing portion for supplying the liquid out of the absorbing materials, and a filter provided at an end portion of the introducing portion. The absorbing materials press against the filter so that an end portion of the interface reaches the filter.Type: GrantFiled: June 28, 2011Date of Patent: April 3, 2012Assignee: Canon Kabushiki KaishaInventor: Hiromasa Amma

Patent number: 8142001Abstract: An ink jet print head manufacturing method and an ink jet print head are provided in which a shape of an adhesive that bonds a support member and a print element substrate together is controlled to maintain a high level of ink ejection performance even if the print element substrate is reduced in size. The adhesive, after being disposed between the support member and the print element substrate, is elongated and then hardened. This process allows the shape of the adhesive to be controlled, securing a sufficient ink path between an ink supply port on the support member side and an ink introducing port on the print element substrate side.Type: GrantFiled: June 12, 2009Date of Patent: March 27, 2012Assignee: Canon Kabushiki KaishaInventor: Isamu Yoneda

Patent number: 8132877Abstract: An ink status conveyance system comprises a maximum monitored ink level sensor operable with respect to an ink source for holding a supply of ink and delivering the ink to a printhead. The ink level sensor is configured to detect when an available amount of ink in the ink source corresponds to an ample ink level. A notification controller is configured to track the available amount of ink in the ink source between an ample ink level and an ink out level. A user interface is configured to enable a user to designate a low ink notification set point for the ink source at any ink level between the ample ink level and the ink out level. The notification controller is configured to compare the user designated low ink notification set point to the available ink volume value to generate a low ink notification when the available ink volume value corresponds to the user designated low ink notification set point.Type: GrantFiled: July 31, 2008Date of Patent: March 13, 2012Assignee: Xerox CorporationInventors: Christopher Ryan Gold, Ernest Israel Esplin, Frederck T.
