ABSTRACT:
Each of first and second caps includes a concave section and a lip section configured to be in contact with a nozzle surface of a droplet ejecting head, so as to seal nozzles when a moving section moves a base toward the droplet ejecting head. The first and second caps are arranged in a second direction intersecting a nozzle alignment direction, the first cap being closer to a pivot section of a cap supporting plate than the second cap is. The concave sections of the first and second caps face different directions from each other. In a state where the second cap seals the nozzles in a part of a plurality of nozzle arrays, the first cap is spaced away from the droplet ejecting head in such a manner that the lip section of the first cap is gradually away from the nozzle surface toward a pivot section side.
