Abstract
A fluid discharging apparatus includes a storage chamber storing a fluid, a discharge port communicating with the storage chamber, a supply unit supplying the fluid to the storage chamber by pressure, a moving object moving in a first direction toward the discharge port and in a second direction away from the discharge port, a pressure changing mechanism, and a control unit controlling the moving object and the pressure changing mechanism. The control unit performs discharge processing, moving processing, and pressure control processing. In the discharge processing, the moving object moves from a closed position closing the discharge port in the first direction to discharge the fluid. In the moving processing, the moving object moves in the second direction while the fluid is discharged from the discharge port. In the pressure control processing, the pressure changing mechanism suppresses a pressure increase in storage chamber.
