摘要： A liquid discharging method comprises the step of displacing the free end of the movable member following the creation of air bubble in the air bubble generating area. For this method, the fulcrum of the movable member is positioned on the side different from liquid discharging side with respect to the displacement area for the free end of the movable member to be displaceable, and at the same time, the free end thereof is arranged to face the effective bubbling area positioned on the downstream side of the central portion of the length of the effective bubbling area that forms the bubble generating area in the direction of the movable member from the fulcrum to the free end thereof, and a part of the effective bubbling area positioned to face the free end of the movable member on the downstream side of the effective bubbling area is arranged to face the displacement area directly. Thus, the initiation of the displacement of the free end of the movable member is effectuated quickly and reliably, and the pressure exerted by the air bubble creation is led to the discharge port side and the fulcrum side of the movable member sufficiently at the time of bubbling, and the development of air bubble that follows is directed to the discharge port side more reliably and efficiently.

摘要： A liquid discharging method for discharging liquid by displacing a movable member by means of air bubble created on the air bubble generating area, which the free end of the movable member faces, comprises the step of promoting the movement of the free end of the movable member by means for promoting the displacement of the free end thereof. With the adoption of this method, the pressure of the air bubble that acts upon the free end of the movable member enables the movable member to form an appropriate displacing configuration to lead the pressure exerted at the time of foaming and the development of the air bubble in the discharging direction efficiently. At the same time, the displacement of the movable member is performed smoothly, thus contributing to enhancing the durability of the movable member.
