摘要： An electrostatic ink-jet head (1) in which the present invention is applied comprises a pressure chamber (6) communicating with an ink nozzle (21), and an atmospheric pressure chamber (12) opened to the atmosphere, with a vibrating plate (5) being provided on the base plane of the pressure chamber (6). Voltage applied between the vibrating plate (5) and an electrode (43) causes the vibrating plate (5) to vibrate due to electrostatic force, thereby discharging ink droplets. A vibrating chamber (41) communicates with a pressure compensating chamber (49), and a displacement plate (16) capable of being displaced in the direction outward from the plane according to fluctuations in the external, atmospheric pressure is formed at the base plane of the pressure compensating chamber (49). Displacement of the displacement plate (16) increases/decreases the volume of the pressure compensating chamber (49), and the internal pressure of the vibrating chambers (41) communicating thereof is adjusted to match the external atmospheric pressure. Accordingly, the vibration properties of the vibrating plate (5) can be maintained constant even when the external atmospheric pressure fluctuates, and proper ink droplet discharging action can be maintained.

摘要： A drive method of an ink-jet head is provided in which a diaphragm is deformed by means of electrostatic force to eject an ink droplet from a nozzle so as to prevent a residual charge from being created between a diaphragm and an individual electrode. The method has first and second drive modes. In a first drive mode a voltage of a first polarity is applied between a diaphragm of the inkjet head (common electrode) and an individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from a nozzle. In the second drive mode a voltage of a second polarity opposite to the first polarity is applied between the diaphragm and the individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from the nozzle at least once for each operation of ink droplet ejection performed in the first drive mode. According to this method, a residual charge created between the diaphragm and the electrode can be removed concurrently with performing the operation of ink droplet ejection by applying positive and negative drive voltage pulses.

摘要： When a nozzle 21 with a stepwise cross-section, which is provided with a small cross-sectional nozzle portion 21a formed on the front side thereof and with a large cross-sectional nozzle portion 21b formed on the rear side thereof in a discharge direction, respectively, is formed by applying etching to a silicon wafer 200 for forming a nozzle plate 2, a resist film 210 is formed on a surface 200a of the silicon wafer 200, and patterning by half-etching and patterning by full-etching is applied to the resist film 210. Next, anisotropic-dry-etching is applied to the silicon wafer 200 by ICP discharge, thereby forming grooves at the full-etched portions. Next, the resist film at the half-etched portions is removed and anisotropic-dry-etching is applied to the portions from which the resist film is removed by ICP discharge. As a result, there can be simply formed on a monocrystalline silicon substrate an ink nozzle having a stepwise cross-section and further having an action, which is larger than that of a conventional ink nozzle, for aligning the directions of pressures applied from cavities to nozzles in a nozzle axis direction.

摘要： Undesirable deflection of partitioning walls between ink pressure chambers is prevented during ink discharge operations even when the partitioning walls are made very thin to achieve a high density inkjet head. The diaphragms of the discharge nozzles of the inkjet head as well as the diaphragms of the non-discharge nozzles are all driven to contact the corresponding individual electrodes, and this diaphragm to individual electrode contact state is maintained in the non-discharge nozzles while the diaphragms of the discharge nozzles are released from individual electrodes to discharge ink. After printing is completed the diaphragms of the non-discharge nozzles are slowly released from the corresponding individual electrodes at a speed that will not cause undesirable ink discharge. By thus maintaining low compliance in the ink pressure chambers of the non-discharge nozzles, deformation of the partitioning walls between discharge and non-discharge nozzles due to change in the ink pressure can be reliably prevented. A drop in ink discharge performance due to such partitioning wall deformation can be reliably prevented, and printing with high resolution, precise print quality can be easily achieved.

摘要： An ink-jet head ejects an ink droplet from an ink nozzle by the charging and discharging between a counter electrode and vibrating plates. The counter electrode comprises a main electrode and an auxiliary electrode, which is provided on the ink-nozzle's side in common with the vibrating plates. Auxiliary charging between the auxiliary electrode and the vibrating plates is effected to vibrate a meniscus in the ink nozzle without ejecting a useless droplet. Consequently, the ink is prevented from forming a film on the meniscus, and an increase of the viscosity of the ink due to evaporation of the ink solvent is prevented by diffusing the ink in the ink passage.
