LIQUID JET RECORDING HEAD AND METHOD OF MANUFACTURE, AND LIQUID JET RECORDER

摘要

PROBLEM TO BE SOLVED: To provide a liquid jet recording head for enabling stabilized high speed continuous printing, a method of manufacture and a liquid jet recorder. SOLUTION: In the liquid jet recording head 10, liquid flowing into a common liquid chamber 22 through a liquid inlet 32 flows along the wall face 12B of a housing 12 and the heating element forming face 18A of a heating element substrate 18 and enters an individual channel 20, as it is. A liquid drop 36 is ejected through heating of a heating element 16. Since the liquid flows linearly from the liquid inlet 32 to the individual channel 20, the liquid flow becomes smooth and bubbles are discharged from a nozzle 28 to the outside and the heating element substrate 18 is cooled by the fluid flowing along it. Stabilized printing is thereby ensured even if the liquid drops 36 are ejected continuously (print) at high speed.
