Abstract

PURPOSE:To inject ink smoothly by small energy by forming a guiding section to the fringe of a vibration section with a small area in the printer which amplifies and transmits the vibration of a piezoelectric vibrator to the vibration section with the small area through a pressure chamber and injects an ink drop. CONSTITUTION:The annular projection 19 is formed to the fringe of the vibration section of a sheet 13 of the on-demand type ink jet printer with an orifice 17 for injecting the ink of an ink layer 16 through the vibration of the piezoelectric vibrator 10, the pressure chamber 11 filled with a conveying medium for conveying and amplifying the vibration of the vibrator and transmitting it to the sheet 13, and the sheet 13. Accordingly, a flow of ink is guided in the orifice direction, ink drops can be injected efficiently through the vibration with small amplitude and power conservation and the improvement of the response of injection can be realized.
