Publication number: 20090207217Abstract: An ink tank includes a first channel extending in the form of a groove on an external part of the tank in connection with an atmospheric communicating port. The tank also includes a second channel which branches off from the first channel and joins this again and which has a capillary force greater than that of the first channel. Even when some amount of ink has flowed out of the atmospheric communicating port, the capillary force generated in the second channel acts to hold the ink in the channel. Additionally, even when ink is stored in the second channel, the first channel is not closed, and the pressure in the tank is therefore kept in equilibrium with the atmospheric pressure. Therefore, there is little possibility that the ink in the second channel will be pushed out even when the ambient temperature changes.Type: ApplicationFiled: January 29, 2009Publication date: August 20, 2009Applicant: CANON KABUSHIKI KAISHAInventor: Shogo Kawamura

Patent number: 7547094Abstract: A liquid discharge recording head includes a recording element with a discharge port for discharging liquid and an electrically connecting portion arranged adjacent to the discharge port and receiving an electric signal for controlling the discharge of the discharge port. The liquid discharge recording head further includes a flexible wiring substrate for covering at least a portion of the recording element. The flexible wiring substrate includes each of a device hole for exposing the discharge port and a bonding hole arranged facing the electrically connecting portion independently. The liquid discharge recording head further includes a sealing agent for covering at least a portion of the electrically connecting portion and filled to at least a portion of the bonding hole. Thus, a liquid discharge recording head that enhances recording performance and that has superior productivity while maintaining reliability of the recording performance is provided.Type: GrantFiled: February 22, 2006Date of Patent: June 16, 2009Assignee: Canon Kabushiki KaishaInventors: Shogo Kawamura, Toshihiro Mori, Hisashi Fukai, Naoki Nakajo

Patent number: 7530678Abstract: A liquid container and its manufacturing method configured to contain a spring member and crimp a flexible member in a frame, wherein positional shift between the flexible member and the fixing member (frame) caused by compression of the spring during manufacturing process is prevented and no device is necessary for spring compression. Accordingly, the liquid container includes a liquid storage portion including a deformable flexible member, a planar portion disposed in the flexible member, and the spring member which abuts on the planar portion to generate negative pressure in the liquid container. The planar portion includes an engaging portion disposed in the planar portion and engaging the elastic portion so as to facilitate holding the elastic portion in a compressed state and releasing the elastic portion from the compressed state.Type: GrantFiled: December 6, 2005Date of Patent: May 12, 2009Assignee: Canon Kabushiki KaishaInventors: Hideki Ogura, Ryoichi Matsumoto, Shogo Kawamura, Ryoji Inoue

Patent number: 7290861Abstract: An inkjet printing apparatus includes a mechanism for opening and closing an ink supply route between an ink tank and a printing head and capable of attaching and removing the ink tank by a horizontal movement. More specifically, a moving member 60 and the communication pipe 51 engaged therewith are moved upward by moving an operation member 70 upward. As a result, the communication pipe 51 moves into an ink lead chamber 16 and a communication channel 52 of the communication pipe 51 comes into communication with the ink lead chamber 16 through its opening. In this way, the ink lead chamber 16, namely, an ink storage chamber 12 comes into communication with a liquid chamber 50 of a printing head 20. An ink supply route is opened in this manner. The ink supply route is closed by the reverse operation to that mentioned above.Type: GrantFiled: June 6, 2005Date of Patent: November 6, 2007Assignee: Canon Kabushiki KaishaInventors: Ryoji Inoue, Ryoichi Matsumoto, Shogo Kawamura, Hideki Ogura, Satoshi Oikawa
