The controller is configured to execute: making of the valve unit to be in an open state, under a condition that a count value indicating an amount of a liquid discharged from the nozzle has reached an opening threshold value ΔV. The opening threshold value ΔV is represented by: ΔV≤(Vtmax−Vi)×Pm/(P−Pm). Note that Vtmax represents a volume of the tank, Vi represents the maximum amount of the liquid storable in the tank, P represents an atmospheric pressure, and Pm represents a meniscus-withstanding pressure of the liquid formed in the nozzle.
