摘要： An ink jet recording head in which a flat plate section has a recess section in its surface and an orifice plate having a plurality of openings grouped and disposed for ejecting a liquid is placed in the recess section, with the flat plate section being cleaned by a cleaning member movable perpendicularly to a direction of the disposition of the ejecting openings in a state brought into contact with a surface of the flat plate section. The recess section includes a combined curved surface made in a manner that a first curved surface having a first curvature and a second curved surface having a second curvature smaller than the first curvature are combined at a position corresponding to the deepest portion of the recess section. At this time, the first curved surface is located on the upstream side of the second curved surface in a cleaning direction of the cleaning member, and the combined curved surface extends in the disposition direction of said ejecting openings. The recess section further includes two inclined surfaces formed at both end portions of the combined curved surface to develop from the surface of the flat plate section. The two inclined surfaces are positioned to be separated by predetermined distances from both end portions of the grouped ejecting openings, respectively. This construction can reduce the ink residual on the recording head after the wiping by the cleaning member.

摘要： A method for manufacturing an ink jet recording head involves forming discharge ports by irradiating a laser beam onto a member which becomes the discharge port plate through a mask having specific patterns thereon. The mask includes a transmission section which regulates the shape of the discharge ports, and an attenuation section formed on the outer circumference of the transmission section so that the further the attenuation section is from the transmission, the less the laser beam becomes. This method also involves forming the discharge ports by irradiating the laser beam through the mask to the member, and each port has a cross-sectional shape which gradually tapers from a rectangular shape at a side of the port connected with the liquid flow path to a circular shape at a recording liquid discharge side of the port.

摘要： An ink container includes an ink containing unit having a housing which directly contains ink, an ink guide, a movable member changing the internal volume of the ink containing unit, and a buffer chamber. The buffer chamber allows changing the internal volume of the ink containing unit when the movable member moves, and has an air communicating portion and is defined by a wall structure. A negative pressure controlling mechanism for controlling the negative pressure in the ink containing unit generated when the ink is guided out of the ink containing unit is provided apart from the housing.
