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: An ink-jet head of the invention includes a head main body, an inflow port, an outflow port, an ink flow path, a nozzle, a heater and a guide unit. The ink flow path is formed inside the head main body to connect the inflow port and the outflow port. Ink flows in the inside of the ink flow path from the inflow port to the outflow port. The nozzle is formed on a side of the ink flow path. The heater is provided in the ink flow path. The heater generates a bubble pressure in the ink flow path, and causes the ink to be discharged from the nozzle. A bubble guide structure is provided in the ink flow path and guides the bubble pressure to the nozzle. The heater may be provided to be eccentric to the nozzle, or the heater may be disposed to be inclined.

Abstract translation: 本发明的喷墨头包括头主体，流入口，流出口，墨流路，喷嘴，加热器和引导单元。 墨流路形成在头主体内部，以连接流入口和流出口。 油墨从流入口向流出口流入油墨流路的内部。 喷嘴形成在墨流路的一侧。 加热器设置在墨流路中。 加热器在墨水流路中产生气泡压力，并使墨水从喷嘴排出。 气泡引导结构设置在墨流路中，并将气泡压力引导到喷嘴。 加热器可以设置成与喷嘴偏心，或者可以将加热器设置成倾斜。
