Abstract
A flow rate control device includes a pressure generating unit that delivers a liquid to a liquid reservoir unit including an ejecting port; a flow rate control unit that controls a flow rate of the pressure generating unit by performing a first flow rate control and a second flow rate control, the first flow rate control being to raise a pressure inside the liquid reservoir unit up to a target pressure at a first pressure change rate which is sufficiently high to float air bubbles adhering to a wall surface inside the liquid reservoir unit, the second flow rate control being to maintain the target pressure or to lower the pressure inside the liquid reservoir unit from the target pressure at a second pressure change rate lower than the first pressure change rate in order to eject air bubbles floating inside the liquid reservoir unit from the ejecting port.
