Abstract: An ink-jet head includes a nozzle array including plural nozzles. The nozzle array has a first nozzle group arranged in the center thereof and second nozzle groups arranged further on outer sides than the first nozzle group. Inter-nozzle pitches of the second nozzle groups are larger than inter-nozzle pitches of the first nozzle group. A direction in which nozzles of the second nozzle group eject an ink and a direction in which nozzles of the first nozzle group eject the ink are different.

Abstract translation: 喷墨头包括具有多个喷嘴的喷嘴阵列。 喷嘴阵列具有布置在其中心的第一喷嘴组，并且在外侧比第一喷嘴组进一步布置的第二喷嘴组。 第二喷嘴组的喷嘴间间距大于第一喷嘴组的喷嘴间间距。 第二喷嘴组的喷嘴喷射墨水的方向和第一喷嘴组喷嘴喷射墨水的方向不同。
