摘要： A liquid discharging method for discharging liquid, which uses the pressure exerted at the time of creating each of bubbles in liquid in a bubble generating area, is arranged to provide two bubble generating areas for generating bubbles in such a manner as to enable these areas to face each other at least partly, hence discharging liquid by means for the pressure thus exerted in the bubble generating areas. In this way, it becomes possible to increase the amount of liquid discharged, as well as to enhance the durability of the movable members, while stabilizing the discharge of liquid from each of the discharge openings.

摘要： A liquid ejection head cartridge includes a liquid ejecting head and a liquid container. The liquid ejection head includes an ejection outlet, a bubble generation region, and a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position. The movable member moves from the first to the second position by pressure produced by the generation of a bubble to permit expansion of the bubble more in a downstream side closer to the ejection outlet. The liquid container includes a substantially prism-like outer wall provided with a substantial air vent portion and having a corner, and an inner wall having a prism-like shape with outer surfaces substantially equivalent to inside surfaces of the outer wall and having a corner portion corresponding to the corner of the outer wall, the inner wall being separable from the outer wall and defining a liquid accommodating portion for containing liquid, the inner wall further having a liquid supply portion for supplying the liquid out of the liquid accommodating portion to the liquid ejection head. The inner wall has a thickness which is smaller in the corner portion than a thickness of a central portion of the outer surfaces of the inner wall.

摘要： A liquid ejection head has a heat generating surface for generating heat for generating bubbles in liquid, the heat generating surface being substantially flush and/or smoothly continuous with an upstream surface of the heat generating surface, a portion above the upstream surface and a further upstream portion being in fluid communication with each other when the heat generating surface does not generate heat, a movable member having a free end and a fulcrum, the movable member and the heat generating surface having a space therebetween, and an ejection outlet for ejecting liquid through generation of the bubble. The ejection outlet opposes the heat generating surface with the movable member interposed therebetween, and an opposing member cooperates with the movable member to direct the bubble toward the ejection outlet. The movable member directs the growing bubble toward the ejection outlet in a direction substantially perpendicular to the heat generating surface.
