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.

摘要： A halftone printing is realized by jetting ink drops of mutually different sizes toward a print medium. Among them, the ink drop having the middle size is set to be a reference ink drop for determining injection timings of the ink drops. When the ink drop to be jetted is bigger than the reference ink drop, an injection timing thereof is delayed relative to that of the reference ink drop. On the other hand, when the ink drop to be jetted is smaller than the reference ink drop, an injection timing thereof is advanced relative to that of the reference ink drop. This allows all the ink drops to be hit upon the print medium precisely at given positions.
摘要翻译：通过向打印介质喷射相互不同尺寸的墨滴来实现半色调打印。其中，将具有中等尺寸的墨滴设定为用于确定墨滴的喷射正时的基准墨滴。当要喷射的墨滴大于参考墨滴时，其喷射定时相对于参考墨滴的喷射时间延迟。另一方面，当要喷射的墨滴小于参考墨滴时，其喷射正时相对于参考墨滴的喷射正时提前。这允许所有墨滴在给定位置上精确地撞击在打印介质上。

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.
