Abstract
A liquid-feeding pump that feeds liquid, which is sucked out from a liquid container, into an ejection nozzle is provided. In addition, a circulation pump that discharges the liquid, which is sucked out from the liquid container, to the liquid container is provided. Moreover, a decompression pump, which generates a pressure for operating the liquid-feeding pump, is used as a drive source of the circulation pump. Therefore, a driving mechanism for the circulation pump need not be additionally provided. Accordingly, it is possible to simplify a configuration of a liquid ejecting apparatus while being capable of agitating the inner portion of the liquid container by using the circulation pump.
