    摘要： In a piezo-electric driver for an ink jet recording head, conductive layers are laminated as an active region in a piezo-electric plate except the front and rear end portions thereof to provide front and rear inactive portions, a pressure facilitating front end plate and a vibrator coupling rear end plate are fixedly mounted on the front and rear inactive portions, respectively, and the front end portion of the piezo-electric plate together with the front end plate are cut at predetermined intervals into pieces, namely, piezo-electric units, which depress the vibrating boards of the ink jet recording head wide to cause the parallel displacement of the vibrating boards thereby effectively pressing the ink in the pressure chamber.

    摘要： An ink jet recording head formed by laminating and fixing: a flow path forming plate having through holes for defining pressure producing chambers, ink supply inlets, and a common ink chamber, a nozzle plate having nozzle openings communicating with the pressure producing chambers, and a vibration plate having diaphragm portions that are resiliently deformed in response to displacement of piezoelectric vibration elements one upon another with an adhesive so as to be watertight. The vibration plate has frame-like thick wall portions that extend as far as to the ink supply inlet side of the pressure producing chamber as well as to the inner side of the nozzle opening, and portions closer to a piezoelectric vibration element than to both ends of the pressure producing chamber are made to be supported by a base. As a result of this construction, a nonsupported region of the pressure producing chamber can be shortened, which in turn improves the rigidity of a substrate unit as a whole.
