IPC: B41J2/045
Filed: 1990-09-10
Abstract: PURPOSE:To obtain stable and efficient ink discharge characteristics by junctioning angular column-type laminated piezoelectric elements arranged in a row to a substrate and arranging a nozzle plate at an opposite position. CONSTITUTION:If a starting pulse is applied to an angular column-type laminated piezoelectric element 1, the element 1 becomes stretched sharply and its upper surface 1b approaches the nozzle orifice 4a of a nozzle plate 4. Then a pressure is applied to the ink 5 and ink droplets are discharged from the nozzle orifice 4a. Subsequently, ink-droplets are discharged from the nozzle plate 4a. At that time, any other part excepting the nozzle orifice 4a is closed by a peripheral protruding part 4b and a center protruding part 4d of a nozzle blade 4. Therefore, the movement of ink to a part other than the nozzle orifice 4a is restricted and ink droplets are formed efficiently by the nozzle orifice 4a and then are discharged. Next, if an ending pulse is applied, the stretched angular column-type laminated piezoelectric element 1 is turned to a contraction process. Consequently, ink 5 is replenished from a base 3c and the device is initialized.
