    摘要： An ink jet recording head for ejecting ink drops by expanding or shrinking a pressure generation chamber of an ink flow route forming member consisting of nozzle openings, the pressure generation chamber, an ink supply port, and a reservoir. Piezoelectric vibrators are disposed and fixed in a row with a predetermined pitch, to a piezoelectric vibrator support plate having excellent cutting properties and the piezoelectric vibrator support plate is fixed to a base made of material having a larger rigidity than the support plate. If the piezoelectric vibrator support plate receives reaction forces when ink is ejected, the base having a larger rigidity than the support plate resists the reaction force and suppresses undesired displacement of the contiguous piezoelectric vibrators.

    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.
