Abstract

PURPOSE:To prevent unnecessary ink jet after ink jet operation by suppressing remaining vibrations, by bonding a restriction plate to a vibration plate facing an ink jet orifice through an ink layer. CONSTITUTION:In a diaphragm type ink droplet jet apparatus wherein vibrations are induced by a piezoelectric vibrator 1 to a transmission medium 4 in a pressure chamber 2, are applified by a horn, are transmitted to the vibration plate 5, and cause through the vibration plate 5 and the ink layer 7 the ink in the ink layer 7 to be jetted as ink droplets from the orifice 8 positioned in front of the vibration plate 5 with the ink layer 7 therebetween, the restriction plate 12 having a through hole 11 with a diameter (d) smaller than the diameter (D) of the tip of the horn is arranged between the tip of the horn of the pressure chamber 2 and the vibration plate 5, and the vibration plate 5 is secured to the restriction plate 12 in such a manner that an annular section of the vibration plate 5 spaced away from the through hole 11 is secured.
