Liquid carrying method, a liquid carrying apparatus, and a liquid discharging method and a liquid discharge head utilizing such liquid carrying method and apparatus

摘要

A liquid carrying method is to carry liquid by pressure exerted by the creation of air bubble, which comprises the step of using an apparatus provided with a first liquid flow path for enabling the carrying liquid to flow, a second liquid flow path provided with the air bubble generating area for creating air bubble, a heat generating device arranged for the air bubble generating area to generate heat for the creation of the air bubble and a movable separation film for separating the first liquid flow path and the second liquid flow path and the step of carrying liquid in the first liquid flow path by displacing the movable separation film, having direction regulating means for regulating the displacement direction of the movable separation film, to the first liquid flow path side by the pressure exerted by the creation of the air bubble. With the method thus structured, it becomes possible to carry liquid efficiently and discharge it from each of the discharge openings stably with high discharge force in good discharge efficiency.
