Recording apparatus

The liquid container comprises: a first chamber that is surrounded by a plurality of walls and is configured to contain a liquid; a liquid inlet port for pouring the liquid into the first chamber; an air opening port that is opened to air; a liquid lead-out port that leads the liquid out of the first chamber; an air lead-in port that is formed in, out of the plurality of walls surrounding the first chamber, a first wall different from the wall constituting a top surface; and an air communication path that allows the air opening port and the air lead-in port to communicate with each other. The air lead-in port is separated from a corner portion where the first wall crosses with another wall.

Liquid container and liquid injection apparatus

In conventional liquid jet apparatuses, improvement in usability is desired. A liquid jet apparatus including a liquid jet head, a liquid container that can store liquid, a housing that covers the liquid jet head and the liquid container, and an operation unit can be operated by a user, a liquid injection port that enables liquid to be injected is formed in the liquid container, when the operation unit is viewed from the front, the first liquid container is arranged between the operation unit and one side wall of the housing, and the second liquid container is arranged between the other side wall opposite to the one side wall of the housing and the operation unit, the housing includes a first cover that covers at least a portion of the first liquid container, and a second cover that covers at least a portion of the second liquid container, and the first cover and the second cover are independently configured to be openable/closable relative to the housing.

Liquid jet apparatus, tank unit, and printer

A tank comprises a container body configured to contain an ink and an ink fill port configured to accept the ink to be injected into the container body. A cap is provided to close the ink fill port when the cap is attached to the tank. The cap comprises a covering portion configured to cover the ink fill port; a seal portion protruded from the covering portion to be inserted into the ink fill port and configured to close the ink fill port when the seal portion is inserted in the ink fill port; and a skirt portion protruded from the covering portion in a direction of protrusion of the seal portion from the covering portion and located away from the seal portion when the covering portion is viewed from a seal portion side. The skirt portion is protruded more than the seal portion.

Cap attached to ink tank of printer

A liquid supplying apparatus, configured to supply a liquid to a liquid ejecting section that is configured to eject the liquid, includes a tank configured to contain the liquid, the tank including a liquid containing section, and a container section connected to the tank. The container section is exposed to air through the tank, and the container section is connected to the liquid containing section of the tank.

Liquid supplying apparatus, liquid ejecting apparatus, and liquid container unit

A recording apparatus includes a recording head configured to discharge an ink onto paper for recording, a case accommodating at least the recording head, a reading device openable and closable between an open position and a closed position, a liquid container having a liquid storage chamber for storing the ink to be supplied to the recording head and an injection port enabling the ink to be injected from the outside to the inside of the liquid storage chamber, a blocking member configured to block the injection port by coming into contact with the injection port, and a cover provided such that the cover can be opened or closed between an open position where the injection port is exposed and a closed position where the injection port is not exposed. The blocking member is mounted on the cover.

There is provided a recording apparatus that can easily set a state in which liquid accommodation units are filled with a liquid for recording while suppressing increases in an installation area. A recording apparatus including a liquid ejecting head that performs recording by ejecting ink onto sheets of paper, a discharge unit in which a discharge opening that includes a discharge region at which the sheets of paper, on which recording was performed by the liquid ejecting head, are discharged, is formed, and liquid accommodation units that are capable of accommodating the liquid that is supplied to the liquid ejecting head, in an apparatus main body, in which the liquid accommodation units are provided with injection openings through which it is possible to inject ink into the liquid accommodation units, which are provided in a positions that are below the discharge unit in a perpendicular direction (&#x2212;Z direction) and overlaps with the discharge unit in the perpendicular direction.

With a conventional liquid container, it is difficult to reduce the possibility of soiling with liquid caused by liquid leakage. Provided is a liquid container including a liquid containing portion containing liquid, a liquid inlet portion receiving injection of the liquid into the liquid containing portion, an open air port that communicates with the liquid containing portion and is introducing the atmospheric air into the liquid containing portion, and a liquid absorbent material that is arranged at least in a portion of the periphery of the open air port and that is absorbing the liquid.

Liquid container, liquid supply device and liquid jet system

An ink tank includes a tank main body that is able to contain ink, an ink filling unit that is provided in the tank main body and has an opening which enables the tank main body to be filled with the ink, and a plurality of ribs that are provided around the ink filling unit of the tank main body and protrude from the tank main body. A clearance in which the ink is held due to a capillary force between the ribs is provided between two adjacent ribs among the plurality of ribs.

Ink tank unit, ink jet printer, and ink tank

Ink tank container for a printer

There is provided a liquid container including a casing that has a side wall surrounding a container portion configured to contain a liquid; a projecting portion that is provided inside of the container portion to be protruded from a fourth wall corresponding to a bottom of the container portion; and a supply port that is provided in the casing to communicate with outside of the casing through an outer area outside of an overlapping area which overlaps the projecting portion in the container portion in a planar view of the fourth wall and discharge the liquid from the container portion. At least part of a second wall provided to face the projecting portion across a first liquid reservoir has optical transparency.

Liquid container with optically transparent area and liquid ejection apparatus including liquid container with visual recognition portion

There is provided a recording apparatus that can easily set a state in which liquid accommodation units are filled with a liquid for recording while suppressing increases in an installation area. A recording apparatus including a liquid ejecting headthat performs recording by ejecting ink onto sheets of paper P, a discharge unitin which a discharge openingthat includes a discharge region at which the sheets of paper, on which recording was performed by the liquid ejecting head, are discharged, is formed, and liquid accommodation unitsthat are capable of accommodating the liquid that is supplied to the liquid ejecting head, in an apparatus main body, in which the liquid accommodation units are provided with injection openings through which it is possible to inject ink into the liquid accommodation units, which are provided in a positions that are below the discharge unit in a perpendicular direction (&#x2212;Z direction) and overlaps with the discharge unit in the perpendicular direction.

A liquid ejection device provided by the invention can be easily transported in a stable orientation in which the weight balance is kept. A printer of the invention includes a liquid ejection head for ejecting ink onto a sheet, ink tanks for storing ink to be supplied to the liquid ejection head, and tubes that connect the ink tanks to the liquid ejection head. An ink injection opening that enables the injection of ink is formed on the upper side of the ink tanks in the vertical direction, and one portion of the ink tanks and another portion of the ink tanks are respectively arranged on one side and another side that face each other across a sheet conveying region.
