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.

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.

摘要： A liquid ejection recording head includes an element substrate provided with a plurality of ejection energy generating elements for generating energy for ejecting liquid, an ejection outlet array comprising a plurality of ejection outlets for ejecting the liquid, and bubble generation chambers for generating bubbles by the ejection energy generating elements. The element substrate includes a first liquid supply port provided, by being penetrated through the element substrate, along an arrangement direction of the ejection outlets and includes a plurality of second ink supply ports disposed between a lateral end of the element substrate and the bubble generation chambers. Each of the bubble generation chambers communicates with the first liquid supply port through a first liquid supply passage and communicates with the second liquid supply ports through a second liquid supply passage. The element substrate has a thermal resistance against heat flowing from the ejection energy generating elements along a direction which is perpendicular to an ejection outlet array direction and which is in parallel to a surface of the element substrate on which the ejection energy generating elements are formed. The thermal resistance, per unit length with respect to the ejection outlet array direction, at both end portions of the ejection outlet array is larger than that at a central portion of the ejection outlet array.

摘要： An object of the present invention is to provide an ink jet print head configured to reduce the inclination of an ink ejection direction to make improper print conditions such as stripes and density unevenness unnoticeable. To achieve the object, an individual wire is extended to lie under a common wire. Thus, wires under ink channels arranged on the respective opposite sides of a pressure chamber 40 are made symmetric. Consequently, an equivalent step structure is provided at the bottoms of the ink channels arranged on the respective opposite sides of a pressure chamber 40.
