Abstract:
Disclosed is an ink jet recording apparatus comprising a piezo-electric body having a plurality of protruding portions; pairs of electrodes each provided on both side surfaces of each protruding portion; a supporting member having a plurality of hollow portions, which are engaged with the plurality of protruding portions in a manner that the space between the top surface of each protruding portion and the inner surface of the bottom of each hollow portion is made an ink room; a plurality of openings each leading to a corresponding ink room; ink supplying devices for supplying ink to the ink rooms; and voltage applying devices for applying voltage between each pair of the electrodes to generate an electric field, which serves to vibrate each protruding portion, thereby jetting ink in the ink rooms in the form of a droplet through the openings.
