20110187793 | HEAD ATTACHMENT MEMBER, LIQUID EJECTION DEVICE, AND HEAD ATTACHMENT METHOD - A plurality of liquid ejection heads is attached to a head attachment member. The head attachment member is disposed so as to face a support drum for supporting an ejection-receiving medium and rotating about a shaft. The head attachment member includes a pair of plate-shaped members each having an attachment surface to which a plurality of head groups each including the liquid ejection heads is attached and a back surface extending parallel to the attachment surface. End parts of the plate-shaped members are connected to each other so as to be able to rotate about a hinge part so that an angle formed by the attachment surfaces is adjustable. | 08-04-2011 |
20110187794 | HEAD ATTACHMENT MEMBER AND LIQUID EJECTION DEVICE - A plurality of liquid ejection heads is attached to a head attachment member with respect to a support drum for supporting an ejection-receiving medium and rotating about a rotation shaft. The head attachment member includes a plurality of attachment surfaces to which a plurality of head groups each including a plurality of liquid ejection heads is attached. Each of the attachment surfaces is arranged so as to be parallel to a tangent line which is tangent to a peripheral surface of the support drum at an intersection point of a line segment which connects the center of the support drum and the center on the first attachment surface between the head groups attached to the first attachment surface. The attachment surfaces are integrally and continuously formed. | 08-04-2011 |
20110187795 | HEAD ATTACHMENT MEMBER AND LIQUID EJECTION DEVICE - A head attachment member, in which a plurality of liquid ejection heads is attached with respect to a support drum for supporting an ejection-receiving medium, includes a plurality of head attachment parts each having a first attachment surface to which head groups are attached with the head groups each including the liquid ejection heads, and a base part having second attachment surfaces to which the head attachment parts are attached. The second attachment surfaces each having a different tilt angle. Each of the first attachment surfaces is arranged to be parallel to a tangent line which is tangent to a peripheral surface of the support drum at an intersection point of a line segment which connects the center of the support drum and the center on the first attachment surfaces between the head groups attached to the first attachment surfaces. The second attachment surfaces are integrally and continuously formed. | 08-04-2011 |
20120147076 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a liquid ejecting head unit including a plurality of liquid ejecting heads in a parallel arrangement. Each liquid ejecting head ejects a liquid from nozzles formed in a nozzle face toward an ejection target object in accordance with a drive signal from a controller. Each liquid ejecting head has an individual two-dimensional code that includes at least a portion of information related to the liquid ejecting head. The liquid ejecting head unit includes a collective two-dimensional code that includes arrangement information of the liquid ejecting heads in the liquid ejecting head unit and collective information related to the information included in the individual two-dimensional codes. | 06-14-2012 |
20120162322 | LIQUID SUPPLYING MECHANISM AND LIQUID EJECTING APPARATUS - A liquid supplying mechanism includes a flow channel forming member that has a base having a plate-like shape on which an upstream portion of a plurality of liquid supplying flow channels are formed so as to supply ink to each of a plurality of liquid ejection heads that are assembled to a liquid ejection head unit, and a plurality of connection members in a tubular shape that extend from one side of the of the base so as to form a downstream portion of the flow channels that individually communicate with the upstream portion of the respective liquid supplying flow channels and are disposed such that the distal end of the connection members correspond to the positions of the connection holes that are formed on the respective liquid ejection heads. | 06-28-2012 |
20120194591 | LIQUID EJECTING APPARATUS AND METHOD FOR MANUFACTURING THE SAME - A storage unit stores temperature correction table in which the temperature T detected by the thermistor is associated with correction information of ink ejection timing, and a printer controller corrects the ink ejection timing of each recording head with reference to the temperature detected by the thermistor and the temperature correction table. | 08-02-2012 |
20150183217 | LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - Provided is a liquid ejecting head including a liquid ejection surface through which liquid is ejected, a head casing body in which the liquid ejection surface is provided on one surface, an atmosphere opening port which is open in an outer-side wall surface of the head casing body, a first space portion which communicates with the atmosphere opening port in the head casing body, and a second space portion which communicates with the first space portion through a connection path. The first space portion reserves liquid entering through the atmosphere opening port. | 07-02-2015 |
20160031210 | LIQUID EJECTING HEAD - A liquid ejecting head includes a fixing plate which includes a bottom surface which is fixed onto the nozzle surface of each of a plurality of head units which are provided to line up in a state in which a first gap is formed along a first direction, and a first side surface which extends from an edge of the bottom surface which is positioned closer to an outside in the first direction than the lined-up head units to the head unit side. The fixing plate includes a second gap which is formed between the first side surface and the head units which are positioned at ends in the first direction among the head units. The liquid ejecting head also includes a second outer circumferential mold which fills at least a portion of the first gap, and a third outer circumferential mold which fills at least a portion of the second gap. The third outer circumferential mold fills the second gap at a position which is distanced further from the bottom surface than the second outer circumferential mold in a direction which is perpendicular to the bottom surface, and a hardness of the third outer circumferential mold is higher than a hardness of the second outer circumferential mold. | 02-04-2016 |
