Abstract

PURPOSE:To obtain densely-arranged nozzles in an ink jet head by laminating in a predetermined order nozzle plates wherein liquid chambers communicated with nozzles are provided in projections thereof and wherein the projections of one of the nozzle plates are not aligned with those of any of the remaining nozzle plates. CONSTITUTION:Three kinds a, b, c of nozzle plates 1 have four ink feed through bores 2, respectively, in the same portions thereof, and nozzles 3 communicated with the bores 2 are provided in the mentioned portions of the nozzle plates 1. Liquid chambers 5 communicated with the bores 2 via grooves 4 are also provided in the nozzle plates 1 such that the liquid chambers 5 in one of the nozzle plates are not aligned with those in any of the remaining nozzle plates. Each of these nozzles plates a, b, c is opened at one surface thereof. Oscillator plates 7 which correspond to the nozzle plates 1 respectively, have projections 8, which correspond to projections 6 in which the liquid chambers 5 are formed, and ink feed bores 9 which are in alignment with the ink feed bores 2. The nozzle plates a,b,c and oscillator plates a, b, c are laminated, and an electrostriueture vibrater 11 to which a signal wire is connected is pasted on the projections 8. Thus, a head plate unit 10 is formed. A plurality of head plate units 10 are laminated to form a multi-nozzle, wherein nozzle plates and oscillator plates are laminated alternately in the menti-oned order a, b and c.
