Patent number: 8430487Abstract: An inkjet recording apparatus includes a joint portion movable to a first position at which communication is established between a flexible tube connected to an ink tank and a recording head and a second position at which such communication is interrupted, a manipulating member rotatably provided on a carriage to take a first posture and a second posture with respect to the carriage, and a link mechanism that causes the manipulating member and the joint portion to operate in conjunction with each other such that the joint portion moves to either of the first position and the second position along with rotation of the manipulating member. The manipulating member is urged to be maintained in either of the first posture and the second posture by a restoration force of the tube.Type: GrantFiled: November 17, 2010Date of Patent: April 30, 2013Assignee: Canon Kabushiki KaishaInventor: Takeshi Sekino

Patent number: 8348401Abstract: A turning operation of a head set lever is completed, and a printing head can be detached from a carriage part. By the above-described turning operation of the head set lever, a supply port insertion and extraction part connected via a link slides, a needle pipe of the supply port insertion and extraction part is brought into a state of being the farthest from the printing head, and a needle insertion and extraction lever is brought into a state in which it moves under a case wall. Thereby, an operator cannot turn only the needle insertion and extraction lever when the head set lever is in an opened state. In this manner, when the head set lever is in the opened state, the operation of the needle insertion and extraction lever, which is used for connection of the supply port insertion and extraction part to ink supply port, is restricted.Type: GrantFiled: August 25, 2011Date of Patent: January 8, 2013Assignee: Canon Kabushiki KaishaInventors: Takeshi Sekino, Tetsuya Ishikawa

Patent number: 8251493Abstract: A recording apparatus which can prevent a drop of a recording head upon attachment of the recording head to a carriage is provided. When a head cartridge is attached/removed to/from a carriage, the carriage is moved to an overlapping position with a head supporting base and stopped there. Projection supporting portions to guide and support rough guide projections on both side surfaces of the head cartridge so as to be properly received to guides provided for the carriage are provided for the head supporting base.Type: GrantFiled: April 13, 2009Date of Patent: August 28, 2012Assignee: Canon Kabushiki KaishaInventors: Takeshi Sekino, Masahiro Taniguro, Takashi Nojima, Hiroki Tajima

Patent number: 8220411Abstract: An object of the present invention is to provide a liquid applying apparatus that enables the viscosity of a liquid to be applied and the condition of supply of the liquid to be detected using conventional mechanisms and without the need for a viscometer or the like, thus allowing prevention of improper application of the liquid to a medium and mitigation of wear of an applying roller or the like, the apparatus having an inexpensive configuration. Thus, according to the present invention, a driving load on an applying roller driving motor is detected when an applying roller is driven. If the driving load is equal to or more than a preset threshold, an operation of re-supplying the liquid is performed by a pump, or an operation of the roller driving motor is stopped.Type: GrantFiled: January 22, 2009Date of Patent: July 17, 2012Assignee: Canon Kabushiki KaishaInventors: Hiroshi Yoshino, Hideaki Nagahara, Tetsuyo Ohashi, Takeshi Sekino, Keisei Hakamata

Patent number: 8146529Abstract: There is provided a liquid application apparatus capable of performing stable application without providing a new mechanism, by efficiently removing an application liquid increased in viscosity and fixedly adhered to an abutting portion between an application member and a liquid supplying member. A liquid application apparatus includes an application member that applies a liquid supplied to an applied face to a printing medium by rotating an application roller and a liquid holding member that abuts against the applied face to form a liquid holding space for holding the liquid, and the amount of liquid that is held in the liquid holding space and makes contact with the application member in unit time is larger before an applying operation for applying the liquid to the printing medium than in the applying operation.Type: GrantFiled: January 22, 2009Date of Patent: April 3, 2012Assignee: Canon Kabushiki KaishaInventors: Keisei Hakamata, Tetsuyo Ohashi, Hideaki Nagahara, Hiroshi Yoshino, Takeshi Sekino

Publication number: 20120050420Abstract: An inkjet recording apparatus includes an ink passage member capable of supplying ink from an ink storage unit to a carriage, a passage connecting member capable of connecting the ink passage member to a recording head, an operating member capable of switching the passage connecting member between a connection state where the ink passage member is connected to the recording head and a disconnection state where the ink passage member is disconnected from the recording head, and an operating-member regulating member regulating the operating member. The operating-member regulating member is capable of switching the operating member between a state where switching to the disconnection state by the operating member is permitted and a state where this switching is prevented.Type: ApplicationFiled: August 24, 2011Publication date: March 1, 2012Applicant: CANON KABUSHIKI KAISHAInventors: Takeshi Sekino, Yasunori Saito, Tsuyoshi Saeki

Patent number: 7594711Abstract: A recording apparatus including a recording head detachably attached on a carriage and a preliminary-discharge receiving unit. The recording head is movable such that an ink discharge surface is movable by a detachable/attachable moving distance in the direction of ink discharge when the recording head is detached from and attached to the carriage. The preliminary-discharge receiving unit is formed such that the distance to the ink discharge surface of the recording head attached on the carriage is set to be a predetermined preliminary discharge distance. The detachable/attachable moving distance is larger than the preliminary discharge distance.Type: GrantFiled: April 21, 2006Date of Patent: September 29, 2009Assignee: Canon Kabushiki KaishaInventors: Takeshi Sekino, Hisashi Taniguchi

Publication number: 20090183672Abstract: A cap sheet metal (and pivot sheet metal) is configured to be able to move linearly with a cap arm (and an arm stay) via engagement between an engagement hole and a fitting shaft. Furthermore, the cap sheet metal (and the pivot sheet metal) can move pivotally with respect to the cap arm (and the arm stay) using the fitting shaft, which engages with the engagement hole, as a pivotal shaft. Thus, even if, for example, the direction of biasing toward the applying roller deviates or a positional relationship with the applying roller deviates slightly, the liquid holding member moves and pivots in the bias direction depending on the deviation. As a result, the contacting pressure of a contacting portion on the applying roller can be made uniform.Type: ApplicationFiled: January 16, 2009Publication date: July 23, 2009Applicant: CANON KABUSHIKI KAISHAInventors: Hideaki Nagahara, Tetsuyo Ohashi, Hiroshi Yoshino, Takeshi Sekino, Keisei Hakamata

Patent number: 7192207Abstract: In both-side recording, wherein the fed recording sheet is conveyed to the recording portion and after the recording is executed on a face side surface, the recording sheet is conveyed to a sheet reversing portion where both sides are reversed, and is sent to the recording portion again where the rear side surface is recorded, a clearance between the recording head and the recording sheet can be changed when recording on the face side or the rear side surface. A first clearance suitable for the recording sheet having a standard thickness and material, and a second clearance greater than the first clearance, can be selected. When there is a possibility that the recording head can come into contact with the recording sheet due to influences from warping and the like, the second clearance is selected, and when there is less possibility of contact, a first clearance is selected.Type: GrantFiled: August 25, 2004Date of Patent: March 20, 2007Assignee: Canon Kabushiki KaishaInventors: Tetsuyo Ohashi, Takeshi Sekino
