20090201332 | HEAD UNIT, LIQUID JET DEVICE, AND METHOD FOR ADJUSTING POSITION OF LIQUID JET HEAD - A head unit for fixing a liquid jet head which ejects liquid includes a base component and movable component that slides on the base component and to which the liquid jet head is fixed. A fixing screw fixes the movable component to the base component. A locating member attached to the base component limits a movement direction in which the movable component moves. The movable component has a contact portion touching the locating member and first and second tapered surfaces formed thereon. A vector normal to the first tapered surface has a first component vector extending in the movement direction. A vector normal to the second tapered surface has a second component vector that is opposite the first component vector and extends in the movement direction. The base component has first and second pins accessible to the first and second tapered surfaces, respectively. | 08-13-2009 |
20100026752 | METHOD OF MANUFACTURING LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - Provided is a method of manufacturing a liquid ejecting head where a head body is fixed in a frame, the head body having a plurality of nozzle rows in which a plurality of nozzles is disposed in rows. The method includes forming the nozzle rows by performing multiple times a process for forming the nozzles by punches while relatively moving the punches and a workpiece on which the nozzles are formed, and performing relative alignment of each of the plural head bodies on the basis of predetermined nozzles selected from among the nozzle rows in accordance with the forming sequence, when the head body is attached to the frame. | 02-04-2010 |
20100026757 | LIQUID EJECTION HEAD UNIT, LIQUID EJECTION HEAD MODULE, AND LIQUID EJECTION APPARATUS - A liquid ejection head unit has a carriage, a liquid ejection head for discharging liquid droplets through a nozzle opening of a nozzle formation surface, and a wiping member. The liquid ejection head and wiping member are moved relative to each other to allow the wiping member to come in contact and slide across the nozzle formation surface of the liquid ejection head so as to wipe the nozzle formation surface. An adhesion prevention plate is provided in the carriage on the downstream side in the wiping direction of the liquid ejection head. | 02-04-2010 |
20100026759 | LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - A liquid ejecting head includes: a head body that includes a plurality of nozzles and ejects liquid drops from the nozzles; a frame that supports the head body; a fixation plate by means of which the head body is fixed to the frame; and a holding plate that applies holding pressure to the fixation plate toward the frame so that the fixation plate is fixed to the frame. | 02-04-2010 |
20110211029 | LIQUID EJECTING APPARATUS - A liquid storage unit for collecting a liquid supplied to an ejecting head is provided. The liquid is supplied to a plurality of ejecting heads via a pressure regulating valve, and the liquid is suctioned from the plurality of ejecting heads by a circulation pump, and then is discharged to the liquid storage unit. In this way, since the liquid is suctioned from each of the ejecting heads, the passage resistance is decreased, so that the ink can be appropriately circulated. In addition, since the ejecting head is supplied with the liquid at an appropriate pressure from the liquid storage unit via the pressure adjusting valve, the liquid can be appropriately ejected. | 09-01-2011 |
20110239431 | HEAD UNIT, LIQUID JET DEVICE, AND METHOD FOR ADJUSTING POSITION OF LIQUID JET HEAD - A head unit for fixing a liquid jet head which ejects liquid includes a base component and movable component that slides on the base component and to which the liquid jet head is fixed. A fixing screw fixes the movable component to the base component. A locating member attached to the base component limits a movement direction in which the movable component moves. The movable component has a contact portion touching the locating member and first and second tapered surfaces formed thereon. A vector normal to the first tapered surface has a first component vector extending in the movement direction. A vector normal to the second tapered surface has a second component vector that is opposite the first component vector and extends in the movement direction. The base component has first and second pins accessible to the first and second tapered surfaces, respectively. | 10-06-2011 |
20130286120 | INK JET RECORDING METHOD, ULTRAVIOLET-RAY CURABLE INK, AND INK JET RECORDING APPARATUS - An ink jet recording method includes ejecting an ultraviolet-ray curable ink of which a viscosity at 28° C. is 8 mPa·s or more from a head to a recording medium, and curing the ultraviolet-ray curable ink attached to the recording medium, wherein, in the ejecting of the ultraviolet-ray curable ink, the ultraviolet-ray curable ink is heated such that a temperature of the ejected ultraviolet-ray curable ink becomes 28° C. to 40° C., and a viscosity of the ultraviolet-ray curable ink at the temperature is 15 mPa·s or less. | 10-31-2013 |
20140253633 | LIQUID DISCHARGING APPARATUS AND METHOD OF CLEANING DISCHARGE HEAD - There is provided a liquid discharging apparatus which includes a discharge head that includes a nozzle forming surface on which nozzles for discharging liquid are formed; a wiping member that performs wiping by relatively moving on the nozzle forming surface while abutting on the nozzle forming surface; a cleaning liquid supply unit that supplies cleaning liquid provided for the wiping; and a control unit that performs reciprocating wiping control which performs the wiping by causing the wiping member for holding the cleaning liquid supplied from the cleaning liquid supply unit to perform a reciprocating operation in which, after relative movement is performed in a first direction along the nozzle forming surface, relative movement is performed in a second direction which is opposite to the first direction. | 09-11-2014 |
20140253634 | LIQUID DISCHARGING APPARATUS AND METHOD FOR CLEANING DISCHARGE HEAD - There is provided a liquid discharging apparatus which includes: a discharge head that includes a nozzle forming surface on which nozzles for discharging liquid are formed; a wiping member that performs wiping by relatively moving on the nozzle forming surface in a state in which a wiping surface abuts on the nozzle forming surface; a cleaning liquid supply unit that supplies cleaning liquid to a liquid supplied surface which is a different surface from the nozzle forming surface and with which the wiping surface can come into contact; and a control unit that causes the wiping surface to abut on the liquid supplied surface to which the cleaning liquid is supplied, and then causes the wiping surface to relatively move on the nozzle forming surface in a state in which the wiping surface abuts on the nozzle forming surface. | 09-11-2014 |
