INK JET HEAD AND INK JET RECORDER

摘要

PROBLEM TO BE SOLVED: To suppress mutual interference surely through a simple arrangement when ink is ejected from a plurality of nozzles. SOLUTION: When ink is supplied from a common liquid chamber 16 through each fluid resistance path 14 to each liquid pressuring chamber 13 and ejected from a nozzle 12 through displacement motion of a diaphragm 15 provided on one side of the liquid pressuring chamber 13 to print on a recording medium, an opening is made in at least one wall face defining the common liquid chamber 16 in order to absorb a pressure generated in the liquid pressuring chamber 13 through free vibration of a pressure buffer region 17 comprising a member having rigidity lower than that of a member constituting the wall face thus reducing mutual interference of adjacent liquid pressuring chambers 13.
