Abstract: An inkjet recording apparatus includes an ink ejection surface, a washing liquid storage portion, a washing liquid nozzle, a mesh sheet, and a sponge member. The washing liquid storage portion includes a supply surface adjacent to the ink ejection surface. The washing liquid nozzle includes a communicating hole that is communicated from a supply port formed in the supply surface to an inside of the washing liquid storage portion, and forms a concave meniscus by a surface of the washing liquid in the communicating hole. The mesh sheet is provided in close contact with an opposite rear surface of the supply surface, and has an opening that is smaller in size than an inner diameter of the communicating hole. The sponge member is provided in a compressed state in the inside of the washing liquid storage portion, presses the mesh sheet toward the opposite rear surface of the supply surface.

Abstract: An ink container includes: an ink pack; and a housing case that houses the ink pack. The ink pack includes: a pack main body filled with ink; a spout attached to the pack main body and including a male screw part on an outer surface thereof; a cap having, on an inner surface thereof, a female screw part to be engaged with the male screw part; and a rotation restricting mechanism.

Abstract: An adjustment mechanism (130) adjusts a position of a target object (110) attached to an attachment base (120). The adjustment mechanism (130) includes a first cam (131) and a second cam (132). The first cam (131) is attached to a shaft portion (123) on the attachment base (120). The second cam (132) houses the first cam (131) and supports the target object (110). The first cam (131) displaces the target object (110) via the second cam (132) by rotating about the shaft section (123) as a rotational axis. The second cam (132) displaces the target object (110) by rotating about the first cam (131) as a rotational axis. An amount of displacement of the target object (110) resulting from rotation of the first cam (131) differs from an amount of displacement of the target object (110) resulting from rotation of the second cam (132).
