Abstract

PURPOSE:To obtain an small-sized effective ink jet recording head having a good characteristic with a reduced drive voltage by fixing a vibration unit formed with a plan vibration element and a vibration plate are adhered to each other, by an annular vibration plate pressing member to a head body. CONSTITUTION:A vibration unit is fixed by a pressing member VPP to a main body to be set practically perpendicular to and coaxial with a main shaft direction of a nozzle NZ. A vibration plate VP of the vibration unit is adapted so that its outer circumferential portion is fixed by the pressing member VPP to the head body. Therefore, when a drive voltage is applied from a lead line LL to a vibration element PCP, the vibration unit is vibrated to the axial direction of the nozzle NZ and a vibration amplitude of a vibration portion VP becomes a maximum in the core portion of the nozzle NZ. Therefore, the vibration of the vibration plate is transmitted efficiently to the nozzle NZ and the ink from an ink tube IT can be received a pressure-modulation and a speed-modulation to efficiently produce an ink droplet.
