摘要： An ink jet print head is capable of creating a state where the direction of ink-drop ejection is not likely to be influenced by air currents generated by the ink ejection, and is capable of printing an image without causing the shifting of dots. To this end, air currents generated by the ejection of ink and the interference among the air currents are reduced by blowing out gas in a direction parallel with the direction of the ink ejection. Accordingly, even with a print head that ejects, at high ejection frequency, ink from multiple ejecting openings formed densely, the advancing direction of the ink drops is unlikely to be deflected. As a consequence, a high-quality, uniform image can be outputted.
摘要翻译：喷墨打印头能够产生墨滴喷射的方向不可能受到由喷墨产生的气流的影响的状态，并且能够打印图像而不引起点的移动。为此，通过在与喷墨方向平行的方向上吹出气体来减少由喷射墨水产生的气流和气流之间的干扰。因此，即使以高喷射频率从多个喷射口喷出墨水的打印头，墨滴的前进方向也不可能偏转。结果，可以输出高质量，均匀的图像。

摘要： The present invention provides a print head that ejects ink supplied through an ink supply port so as to prevent the size of satellites from being reduced while inhibiting an increase in resistance to an ink flow. In the print head, ink supply ports are arranged on both sides of a plurality of channels. A predetermined number of ink supply ports are arranged at least one side of the ink channel all over the range of the arrangement of the channels. One side of each of the plurality of channels is connected via the common liquid chamber to the liquid supply port located so as to extend in a direction in which the channels are arranged.
