    Abstract: An inkjet recording apparatus includes a first storage part, a second storage part, an ejection part, a first supply path, a regulation part, and a second supply path. The second storage part is provided higher than the first storage part. The ejection part includes an ejection port. The first supply path is used for supplying ink from the first storage part to the second storage part and has a discharge port which is provided in the second storage part at a level higher than a predetermined specific position and lower than the ejection port. The regulation part regulates a backflow of ink in the first supply path. The second supply path is used for supplying ink from the second storage part to the ejection part and has a supply port which is provided in the second storage part at a level lower than the discharge port.

    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).

    Abstract: A maintenance unit used in an ink-jet recording apparatus including a plurality of recording heads having ink ejection surfaces includes a plurality of wipers, a carriage, a support frame, a drive mechanism, and a lifting and lowering mechanism. The plurality of wipers may be positioned so as to correspond to the plurality of recording heads, and are configured to wipe ink ejection surfaces of the plurality of recording heads. The drive mechanism is configured to reciprocate the carriage along the support frame. The lifting and lowering mechanism is configured to lift and lower the support frame together with the carriage toward and away from the ink ejection surfaces. By reciprocating and lifting and lowering the plurality of wipers, the ink ejection surfaces of the plurality of recording heads may be wiped by the plurality of wipers. The maintenance unit may be used in an ink-jet recording apparatus.

    Abstract translation: 在包括具有喷墨表面的多个记录头的喷墨记录装置中使用的维护单元包括多个擦拭器，滑架，支撑框架，驱动机构和升降机构。 多个擦拭器可以被定位成对应于多个记录头，并且被配置为擦拭多个记录头的喷墨表面。 驱动机构构造成使托架沿着支撑框架往复运动。 提升和降低机构被配置为将支撑框架与支架一起提升和降下，以朝向和远离喷墨表面。 通过使多个擦拭器往复运动并提升和降低，多个记录头的喷墨表面可以被多个擦拭器擦拭。 维护单元可以用在喷墨记录装置中。
