Abstract: There are provided a liquid ejecting head configured to eject a liquid in an ejection direction; and a support unit having a support body that supports the liquid ejecting head and a base portion that supports the support body, and the support body is rotatable about a rotation shaft extending in a direction orthogonal to the ejection direction with respect to the base portion.

Abstract: A pressure adjustment unit includes a flow passage including a first chamber, a second chamber, and a through hole. The apparatus further includes a partition wall that the through hole is formed, a first sealing portion having flexibility, a second sealing portion facing with the first sealing portion, a valve configured to close the flow passage by moving in a first direction, and to open the flow passage by moving in a second direction opposite to the first direction, a biasing member biasing the valve in the first direction, and a restricting portion restricting movement of the valve in the first direction by contact with a to-be-restricted portion of the valve, at a second portion different from a first portion where contact of the first sealing portion and the second sealing portion occurs.

Abstract: A liquid ejecting apparatus includes a head unit having heads that configure to eject a liquid in a first-direction, and in which a second-direction orthogonal to the first-direction is a short direction and a third-direction orthogonal to the first and second-directions is a longitudinal direction, and a holding member. The head unit has a first-head, a second-head adjacent to the first-head, and disposed in the second-direction, and a third head adjacent to the second-head, and disposed in the second-direction. The first head has a first-gripping portion provided on an upper surface. The second-head has a second-gripping portion provided on the upper surface. The third-head has a third-gripping portion provided on the upper surface. A position of the second-gripping portion with respect to the third-direction is different from positions of the first-gripping portion and the third-gripping portion with respect to the third-direction.

Abstract: A pressure adjustment unit includes a valve body including a base end portion, a shaft portion protruding in a first-direction from the base end portion, and an elastic member, and a casing that has a partition wall formed with a through hole into which the shaft portion is inserted, and a first-wall protruding in a second-direction opposite to the first-direction to define the first-chamber. On a first-chamber side of the partition wall, a valve seat, which is annular, is provided around the through hole to block a flow path by contacting with the elastic member, an outer periphery of the base end portion has a positioning region, and a distance between a first-direction-side end portion of the positioning region and a first-direction-side distal end of the shaft portion is shorter than a distance between the valve seat and a second-direction-side end portion of the first-wall.

Abstract: A liquid ejecting head configured to eject a liquid in a first direction includes an upper surface facing a direction opposite to the first direction, and a gripping portion provided on the upper surface to grip the liquid ejecting head.

Abstract: An ink jet head including a body portion including a pressure generating portion, and a nozzle that discharges ink, a relay substrate that relays between the body portion and a printer, a cable that sends an electric signal from the printer to the relay substrate, and a cover unit that covers a cable connector that electrically couples the relay substrate and the cables to each other. The cable is drawn out to a portion external to the ink jet head through an opening portion open on a gravitational direction side with respect to the cable connector.
