INK JET RECORDING HEAD, INK JET RECORDER AND METHOD FOR MANUFACTURING HEAD

摘要

PROBLEM TO BE SOLVED: To provide an ink jet recording head realizing stabilized high speed continuous printing, its manufacturing method, and an ink jet recorder. SOLUTION: A bubble generated in a common liquid chamber 22 moves through a sufficiently large interconnection port 26 and a supply channel 30 to the ink tank side. Since the interconnection port 26 is formed to pass a bubble generated in the common liquid chamber 22, the bubble is discharged well from the common liquid chamber 22 and ink supply to the common liquid chamber 22 and an individual channel 20 (nozzle 18) is not damaged by a bubble. Consequently, stabilized printing is ensured even when ink is ejected (printed) continuously at a high speed.
