摘要： An ink drop is injected via a nozzle by changing drive voltages applied to a piezoelectric element to reduce the volume of a pressure chamber filled with ink, so that the injected ink drop hits upon a print medium to carry out printing. Upon injecting the ink drop via the nozzle, an injection timing of the ink drop is changed corresponding to a drive frequency of the drive voltages using a predetermined rule. The predetermined rule may be a table defined in terms of drive frequencies of the drive voltages and optimum injection timings of the ink drop corresponding to the drive frequencies.

摘要： Each of common electrode teeth 76-1, 76-2 and 76-3, and each of individual electrode teeth 77-1 and 77-2 are alternately arranged in the X1-X2 direction at predetermined intervals g. When a positive voltage is applied to the individual electrode teeth 77-1 and 77-2, an electric field 83-1 indicated by a line of electric force 82-1 is produced in a piezoelectric plate member 65 between the individual electrode tooth 77-1 and the common electrode tooth 76-1 and an electric field 83-2 indicated by a line of electric force 82-2 is produced between the individual electrode tooth 77-1 and the common electrode tooth 76-2. Likewise, an electric field 83-3 indicated by a line of electric force 82-3 is produced between the individual electrode tooth 77-2 and the common electrode tooth 76-2 and an electric field 83-4 indicated by a line of electric force 82-4 is produced between the individual electrode tooth 77-2 and the common electrode tooth 76-3. Depending on the piezoelectric constant d33, X1-X2 direction components of the electric fields causes the piezoelectric plate member 65 to expand efficiently, as indicated by numerals 83-1-83-4. An expanding action of the piezoelectric plate member 65 causes a bimorph element 69 to bulge into a dome configuration.
