    摘要： A head chip and a recording liquid storing unit are bonded through a sealing member. The head chip comprises a recording element base plate, and a flow path formation member provided with a bonding face and a supply hole. The frame member of the recording liquid storing unit is formed by a single member, which is provided with a recording liquid storing chamber, one side face of which forms a totally open portion. The shape of the opening portion is equal to the sectional shape of the recording liquid storing chamber. For the flat portion of the sealing member, there are formed a hole portion, the circumferential first face-side ribs that surround it, and the second face-side ribs, which are exactly symmetrical to the first face-side ribs, with the flat portion between them. These ribs are compressed and held by both bonding faces. An inner extrusion of the rib on the flat portion is fitted into the position hole of the bonding face. Through the sealing member thus arranged, the recording liquid storing unit and the head chip are connected to simplify the connecting structure.

    摘要： A liquid discharge recording head includes an orifice plate having a discharge port formed therefor to discharge liquid, and a main body portion having liquid flow paths formed therein to communicate with an opening arranged at an edge portion thereof, the discharge port and the opening being bonded to communicate with each other. A sealing groove is arranged on the circumference of the opening along the bonded face, and a filler is filled in the sealing groove. This makes it possible to pour filler into the sealing groove from the injecting groove after the orifice plate is bonded to the face having the opening formed therefor to communicate the opening with the discharge port of the orifice plate to eliminate any gaps from which the filler leaks between the orifice plate and the face having an opening formed therefor, and carry out sealing without clogging the circumference of opening or discharge port.

    摘要： 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.

    摘要： The landing precision of ink drops is improved to improve the image quality and increase the printing speed. An inkjet print head ejects ink supplied from an ink supply port from a plurality of ejection ports respectively connecting to ink paths having different flow resistances by using energy generated by a plurality of electrothermal transducer elements respectively corresponding to the plurality of the ejection ports, wherein each of the plurality of the ejection ports connected to the ink paths having a low ink flow resistance is arranged so that the center of each of the plurality of the ejection ports is positioned farther away from the ink supply port to the center of the corresponding electrothermal transducer element than each of the plurality of the ejection ports connected to the ink paths having a high ink flow resistance.
