20110074884 | INKJET HEAD - To provide an inkjet head which includes high-density nozzle rows and which does not easily cause an ejection failure due to adhesion of ink mist around ejection orifices when a high-density image of a secondary color is printed with a small number of paths. An inkjet head includes at least two or more types of nozzle rows that eject different amounts of ink. When A is the cross section, with respect to an ink supplying direction, of an ink supply path from each ejection orifice to a supply port and L is the length of the ink supply path, the value of A/L differs between the two or more types of nozzle rows. The nozzle row of which the value of A/L is small is disposed outside an area between the nozzle rows that eject a largest amount of ink and that are arranged next to each other. | 03-31-2011 |
20130321528 | LIQUID DISCHARGE HEAD AND LIQUID DISCHARGE APPARATUS - The invention stabilizes a posture of a liquid discharge head when mounting the liquid discharge head with respect to a mount section of a liquid discharge apparatus and improves the mountability thereof. The liquid discharge head includes a grasp portion provided with a surface extending along a first direction as a direction of disposition of a plurality of discharge ports and extending along a second direction intersecting the discharge port surface and used for grasping the liquid discharge head. The surface of the grasp portion is provided at a position not overlapped in the direction vertical to the discharge port surface with a center axis passing in a third direction which is vertical to the first direction and extending along the discharge port surface through the center of gravity of the liquid discharge head in the first direction. | 12-05-2013 |
20150343767 | LIQUID EJECTING HEAD AND SUPPORT MEMBER - There are provided a liquid ejecting head and a support member that can achieve both of breakage avoidance of a print element substrate and deformation suppression of the support member. Therefore a plate thickness of an adhesion part in the support member is thinner that a plate thickness of a main surface other than the adhesion part. | 12-03-2015 |
20150343770 | LIQUID EJECTION CARTRIDGE AND LIQUID EJECTION APPARATUS - A liquid ejection head includes a liquid ejection section including an element substrate having ejection ports for ejecting liquid and an electrical wiring substrate connected to a contact of the liquid ejection apparatus to transmit signals to the element substrate, a liquid tank loading section including a containing space for containing a liquid tank storing liquid to be supplied to the element substrate and a lock member having an engaging part for engaging with a holding part of the liquid tank and a fixation means for rigidly securing the liquid election section and the liquid tank loading section in position. | 12-03-2015 |
20150343771 | LIQUID EJECTION HEAD, LIQUID EJECTION DEVICE AND METHOD OF ELECTRICALLY CONNECTING LIQUID EJECTION HEAD AND LIQUID CONTAINER - A liquid ejection head includes a recording element substrate for ejecting liquid, a mounting section to be loaded with a liquid container, and a connector equipped with a contact spring capable of expanding and contracting in an axial direction to be brought into contact with a contact substrate provided on the liquid container. The axial direction of the contact spring being inclined relative to the direction of loading the liquid container in the mounting section. | 12-03-2015 |
20150343772 | LIQUID EJECTION HEAD - A liquid ejection head including: an ejection section for ejecting liquid; an electrical wiring substrate having terminals to be electrically connected to the respective electrical contacts of a liquid ejection apparatus; a first loading section to be loaded with a first liquid storing container; and a second loading section to be loaded with a second liquid storing container having a width greater than the first liquid storing container; the wall of the liquid ejection head being provided with a rib extending in the height direction on the surface opposite to the surface mounted by the electrical wiring substrate; the second loading section and the rib being arranged at respective positions where the second loading section and the rib overlap with each other as viewed in the direction of loading the second liquid storing container in the second loading section. | 12-03-2015 |
20150343775 | LIQUID EJECTION HEAD AND MANUFACTURING METHOD OF LIQUID EJECTION HEAD - A liquid ejection head with high environmental reliability which suppresses a crack of a Si substrate and peeling-off of an ejection port forming member by relaxing a residual stress in a printing element substrate and a manufacturing method of a liquid ejection head are provided. For that purpose, after the printing element substrate is bonded and fixed to a support member, the support member is screwed and fixed through an elastic member. | 12-03-2015 |
20150343791 | LIQUID EJECTION CARTRIDGE AND LIQUID EJECTION APPARATUS - A liquid ejection cartridge having a liquid ejection section for ejecting liquid includes an electrical contact section to be electrically connected to a terminal section of an apparatus main body, the electrical contact section being formed by a plurality of printed substrates arranged on a same surface. | 12-03-2015 |
