Ink jet recording head, ink jet recording cartridge, and recording apparatus

摘要

An ink jet recording head comprising an element base having a plurality of energy generating elements for generating energy used for discharging ink, a grooved top plate having a plurality of grooves corresponding to the plurality of energy generating elements, being joined to the element base, and having a plurality of ink flow channels formed by the plurality of grooves on a joint area side to the element base, an orifice plate having a plurality of orifices having communication with the plurality of ink flow channels respectively and being mounted on the grooved top plate integrally, and a chip tank having supply passages for supplying ink to the plurality of ink flow channels and having a shroud portion for shrouding the orifice plate, wherein a surface in the side of the plurality of orifices of the orifice plate is substantially parallel with the shroud portion of the chip tank and is inclined relative to the element base. The orifice plate is inclined to the element base, by which it can be arranged in parallel with the record medium surface and ink can be discharged perpendicularly to the record medium, and therefore high-quality recording is achieved without being so much affected by cockling of a record medium or a high-speed motion. <IMAGE>
