Ink jet printing head having ink chambers arranged in succession by lamination

摘要

An ink jet printing head comprises a plurality of ink liquid chambers (pressure chambers) 13 connected to an ink supply source and arranged in a predetermined direction and a plurality of nozzles 11a individually connected to the ink liquid chambers 13 and arranged in the predetermined direction. Plate-shaped members 14, 15, 17 and 18 lying between the ink liquid chambers 13 and having a piezoelectric plate member capable of discharging ink in the ink liquid chambers are arranged by being laminated in the arrangement direction of the nozzles 11a. By this configuration, a multi-nozzle ink jet printing head with high-density nozzle arrangement can be realized.
