摘要： A liquid jet recording head includes liquid discharge ports, pressure chambers, and a substrate which has the discharge energy generating element, a liquid chamber for storing a liquid supplied to the pressure chamber, a pair of paths which are separated from the liquid chamber, and a liquid supply port communicating with the liquid chamber. A liquid inlet port communicating with one path of the pair of paths and a liquid outlet port communicating with the other path of the pair of paths are opened on one surface of the substrate. A liquid flow path for discharging the liquid from the liquid chamber to the pressure chamber via the liquid supply port, and a liquid flow path for circulating the liquid from the one path to each pressure chamber via the liquid inlet port, and further from each pressure chamber to the other path via the liquid outlet port are provided.

摘要： A print head that ejects ink supplied through an ink supply port can 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 at 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.

摘要： A liquid ejection recording head includes an element substrate having plural ejection energy generating elements, an ejection outlet array of plural ejection outlets, and bubble generation chambers. The element substrate includes a first liquid supply port provided along an arrangement direction of the ejection outlets, and plural second ink supply ports disposed between a lateral end of the substrate and the chambers. Each bubble generation chamber communicates with the first and second liquid supply ports through first and second liquid supply passages, respectively. The element substrate has a thermal resistance against heat flowing from the ejection energy generating elements along a direction perpendicular to the array direction and parallel to a surface of the substrate. The thermal resistance, per unit length with respect to the array direction, at both end portions of the array is larger than that at a central portion of the ejection outlet array.
