    Abstract: A liquid discharge method for discharging a liquid through a discharge port (1) for discharging the liquid utilizing a bubble (6) by displacing a movable separation film (5) for always substantially separating a first liquid flow path (3) in communication with said discharge port (1) for discharging the liquid from a second liquid flow path (4) comprising a bubble-generating region for generating the bubble (6) in said liquid, on the upstream side of said discharge port with respect to flow of the liquid in said first liquid flow path (3), comprises a step of displacing a downstream portion of said movable separation film (5) toward said discharge port (1) relatively more than an upstream portion of said movable separation film (5) with respect to a direction of the flow of the liquid.

    Abstract: Liquid is discharged at a high frequency in a consecutive manner with a liquid discharge head having a movable member 11. A bubble 40 formed for discharge a first discharged droplet 66a grows large into a discharge port 4 side by the movable 11 substantially closing a common liquid chamber 6 side in a bubble forming procedure, and disappears fast at the common liquid chamber 6 side by the movable member 11 releasing the common liquid chamber 6 side of a flow path 3 in a bubble disappearance procedure, and reaches a state to remain at the discharge port 4 side of a heat-generating body 10. Under this state, since the bubble 40 disappears at the common liquid chamber 6 side, a constant liquid is refilled to reach the discharge port 4 side, and the bubble 40 does not yet completely disappear, a meniscus is disposed comparatively closer to a liquid discharge face. Under the circumstances, if discharge of a second discharged droplet 66b is arranged to start from this state, the liquid can be discharged well at a short interval in a consecutive manner.

    Abstract: According to the present invention, a liquid discharge head comprises: an element substrate (1), on the surface of which a plurality of energy generation elements (2) are arranged in parallel to generate electrical energy that is applied to eject a liquid; a top plate (3), which is positioned facing the element substrate and which defines a plurality of liquid flow paths (7) that correspond to the energy generation elements and that communicate with discharge orifices (5) whereat a liquid is ejected; one or more flow rate detection elements (200), which are provided for each of the liquid flow paths to detect the flow rate at which the liquid flows along each of the liquid flow paths; and an energy generation element controller, for controlling, based on the results output by the flow rate detection elements, the condition under which the energy generation elements are driven.

    Abstract: Provided is a recording head substrate on which are mounted energy generating elements that contribute to the formation of images by a recording head, and on which both light-receiving elements and light-emitting elements, or at least, light-receiving elements are mounted. In addition, provided is a recording head substrate on which are mounted energy generating elements that contribute to the formation of images by a recording head, and on which are mounted a plurality of head position detecting elements for detecting the position of the recording head.
