INK CHANNEL STRUCTURE AND INK JET HEAD INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an ink channel structure that improves ink discharge characteristics by reducing residual pressure waves remaining in a pressure chamber in a short period of time and an ink jet head including the same.

SOLUTION: The ink channel structure includes the pressure chamber 210 for storing ink that has flowed therein to be discharged to a nozzle, and a channel 230 that repeats expansion and contraction in a direction toward the pressure chamber 210 for supplying ink to the pressure chamber 210 after the ink is discharged by pressure generated from the pressure chamber 210 and reducing the residual pressure waves remaining in the pressure chamber 210.
