摘要： PROBLEM TO BE SOLVED: To efficiently guide a foaming pressure towards a discharge opening to contribute to discharging by substantially shutting the movement of air bubbles to the upstream side of an air bubble generation region. SOLUTION: A heating unit 10, a movable member 11, and stoppers 12a and 12b for regulating a movement of the movable member 11 to a desired range are set in a flow path 3. A liquid is discharged from a discharge opening 4 by an energy when air bubbles are generated. The movable member 11 has a free end 11b of a breadth larger than a breadth of the heating unit 10. The free end 11b is opposed to a central region of an air bubble generation region formed by the heating unit 10. A stopper includes the leading end stopper 12a which comes in contact with the free end 11b of the moved movable member 11, and the lateral stopper 12b positioned with respect to the side of the air bubble generation region. At least part of the lateral stopper 12b substantially comes in contact with both sides of a side end of the moved movable member 11. The lateral stopper 12b regulates air bubbles 40 generated from the air bubble generation region by the contact to the movable member 11.

摘要： PROBLEM TO BE SOLVED: To reduce satellites at the ejection of liquid. SOLUTION: A liquid in a liquid passage 10 is heated by a heating resistor 2 to generate a bubble 40 and a movable member 31 is deformed by the bubble 40 to be contacted to a stopper 64, thereby ejecting the liquid from an ejection nozzle 18. After that, while the movable member 31 is going to be in the deformed condition before the vibration of the movable member 31 which is restored to its initial condition is attenuated due to the contraction of the bubble 40, the heating resistor 2 is driven again to generate a bubble 40. As a time-lag between generating/growing of the bubble 40 and deformation of the movable member 31 is reduced, an interval from starting of the contraction of the bubble 40 to releasing of the closing in the upstream side of the liquid passage 10 by the movable member 31 is reduced and a time period in rapid receding of a meniscus M is reduced so that a thin part 68 in a tail section between an ejected drop 66 and the meniscus is markedly shortened. As a result, only the thin part becomes the separated part, thereby preventing occurrence of a satellite 67.

摘要： PROBLEM TO BE SOLVED: To prevent a fluctuation stage of a front part of a bubble in a liquid ejecting head from being disturbed due to the growing of the rear part in the stage of the transition of the bubble from the growing of the front to the contraction of the rear part. SOLUTION: A heating resistor 2 for generating a bubble 40 in a liquid, a movable member 31 which is deformed along with the growing of the bubble 40 and a stopper 64 that restricts the deformation of the movable member 31 in a desired range are provided to a bubble generating region 11 in a liquid passage 10 which is communicated to an ejection nozzle 18 for the liquid. A region passing through a range from a side end of the ejection nozzle 18 of the heating resistor 2 to a central section thereof and the center of the ejection nozzle 18 is in a straight communication condition wherein only the liquid can be existing. The movable member 31 has a free end 32 at a position opposite the central section of the bubble generating region 11 in a stand-by condition. The free end 32 is substantially contacted to the stopper 64, then a maximum liquid passage resistance of the liquid passage is formed at the upstream side rather than the bubble generating region 11 so that components of the maximum bubble at the upstream side is made roughly constant.
