  • Patent number: 10384227
    Abstract: A fluid discharging apparatus includes an accommodation unit that accommodates a fluid, a discharge port that communicates with the accommodation unit, a moving object that moves in a first direction toward the discharge port and in a second direction away from the discharge port in the accommodation unit, and a control unit that controls driving of the moving object. The control unit performs discharging processing and moving processing. In the discharging processing, the discharge port is opened by moving the moving object from a closed position at which the discharge port is closed, in the second direction, and then the fluid is extruded and discharged from the discharge port by moving the moving object in the first direction. In the moving processing, the moving object is moved in the second direction during a period when the fluid is discharged from the discharge port in the discharging processing.
