20130033539 | LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - A liquid ejecting head includes: a head main body having a manifold in which ink is retained, a compliance section absorbing a pressure change inside the manifold and a compliance space provided opposite to the compliance section, and discharging liquid from nozzles communicating with the manifold; an air chamber communicating with the compliance space and outside; and a liquid reservoir communicating with a liquid flow path supplying liquid to the manifold and volume of which is larger than the manifold, wherein the air chamber and the ink reservoir are divided by a resin adhesive where water vapor is capable of penetrating. | 02-07-2013 |
20130057623 | LIQUID EJECTION APPARATUS - A printer includes a filter unit having a distribution flow path through which the introduced ink flows into a recording head, and an air bubble trap in which air bubbles which have entered ink in the distribution flow path are collected, the air bubble trap being provided with a waterproof member having a waterproof property and an air permeability that forms part of a wall of the air bubble trap. A printer includes an air bubble suction mechanism that suctions air bubbles collected in the air bubble trap through the waterproof member. | 03-07-2013 |
20150367638 | INKJET-HEAD AND INK JET PRINTER - An inkjet-head includes a first flow path member in which a plurality of first flow paths are formed; and a second flow path member in which a plurality of second flow paths are formed and to which the first flow path member is bonded. The second flow paths have intra-joint-surface flow paths, respectively, which are formed by surrounding, with a first adhesive, a peripheral edge of a groove formed in the second flow path member and bonding the first flow path member thereto. A joint space is formed and includes a plurality of the intra-joint-surface flow paths due to surrounding, with a second adhesive, an outer periphery of the intra-joint-surface flow path and bonding the second flow path member and the first flow path member. At least a part of the second adhesive is formed further inside of a straight line connecting an end of one intra-joint-surface flow path on the outer side and an end of another intra-joint-surface flow path on the outer side in joined surfaces. | 12-24-2015 |
20150367649 | FLOW PATH MEMBER, LIQUID EJECTING HEAD, AND LIQUID EJECTING APPARATUS - There is provided a flow path member including a flow-path member main body which is provided with a liquid supplying path through which liquid is supplied to a head main body that ejects liquid and an attaching portion to which a liquid supplying unit that supplies liquid of the liquid supplying path is attached; and a sealing member which is provided with an insertion hole into which the attaching portion is inserted, and is interposed between the liquid supplying unit and the attaching portion, in which a convex portion is provided in any one of the inner surface of the insertion hole and the outer surface of the attaching portion, and a concave portion that fits with the convex portion is provided in the other of the inner surface of the insertion hole and the outer surface of the attaching portion. | 12-24-2015 |
20150375502 | INK JET PRINTER AND CONTROL METHOD THEREFOR - An ink jet printer includes an attachment detection portion that detects an attachment of an ink storage member that retains an ink in an absorber contained in the ink storage member itself; an ink jet recording head that ejects an ink flown in from the ink storage member; and a control circuit that controls ink ejection performed by the ink jet recording head. The control circuit is configured to, upon detection, by the attachment detection portion, of an attachment of the ink storage member to be newly used, perform control so as to cause a first operation mode to be set, and thereafter, perform control so as to cause the first operation mode to be switched to a second operation mode, upon satisfaction of a condition in that a total discharge amount of an ink ejected in the first operation mode reaches a prescribed amount. Further, a per-unit-time discharge amount of an ink ejected in the first operation mode is set so as to be smaller than a per-unit-time discharge amount of an ink ejected in the second operation mode. | 12-31-2015 |
20150375506 | INKJET-HEAD AND INK JET PRINTER - An inkjet-head includes a first flow path member in which a first flow path is formed; and a second flow path member in which a second flow path is formed and to which the first flow path member is bonded. The second flow path has an intra-joint-surface flow path which is formed by surrounding, with a first adhesive, a peripheral edge of a groove formed in the second flow path member and bonding the first flow path member thereto. A joint space is formed and includes the intra-joint-surface flow path due to surrounding, with a second adhesive, an outer periphery of the intra-joint-surface flow path and bonding the second flow path member and the first flow path member thereto. At least a part of an atmosphere opening path which causes the joint space to be open to the atmosphere is formed by sealing an atmosphere opening groove formed in the joint space using a film. | 12-31-2015 |
20150375545 | INK JET PRINTER - Provided is an ink jet printer including an ink jet head that has a nozzle surface on which nozzles for ejecting liquid are open; and a carriage on which the ink jet head is mounted, in which the carriage is scanned from one end at which a scanning reference point of the carriage is set to the other end via an area through which a liquid impacted object passes, the ink jet head is mounted to the carriage in a state of being deviated to one end in a scanning direction from a center of the carriage in the scanning direction, and a space is provided on a lateral side at the other end of the ink jet head in the carriage by deviating the ink jet head to the carriage. | 12-31-2015 |
20160114592 | FLOW CHANNEL STRUCTURE AND LIQUID EJECTING APPARATUS - A flow channel structure includes a first flow channel chamber to which an ink is supplied, a first sealing body that configures a wall face of the first flow channel chamber, a valve body that controls flow and blocking of the ink in accordance with deformation of the first sealing body, a second flow channel chamber that communicates with the first flow channel chamber, and a second sealing body that configures a wall face of the second flow channel chamber, in which the rigidity of the second sealing body is greater than the rigidity of the first sealing body. | 04-28-2016 |
