摘要： A liquid ejecting apparatus includes a liquid ejecting unit including at least one pressure chamber filled with a reactive ink, at least one nozzle communicating with the pressure chamber, a supply channel through which the reactive ink is supplied to the pressure chamber, and an elastic compliance film forming a portion of the supply channel; a piezoelectric element that changes a capacity of the pressure chamber when an electric signal is supplied to the piezoelectric element; and a flexible wiring substrate at which a signal wire for supplying the electric signal to a connection terminal of the piezoelectric element is formed. The elastic compliance film is formed of a para-aramid resin. The connection terminal and the signal wire are electrically connected to each other by solder.

摘要： A liquid ejecting apparatus includes a nozzle for ejecting liquid, a pressure chamber communicating with the nozzle, a first individual flow path communicating with the pressure chamber, a second individual flow path communicating with the pressure chamber, a pressure generating unit changing a pressure of the liquid in the pressure chamber, and a control unit for driving the pressure generating unit. In the liquid ejecting apparatus, the liquid is supplied into the pressure chamber via one of the first individual flow path and the second individual flow path, and at least a part of the liquid supplied into the pressure chamber is discharged via the other. The control unit introduces air into the pressure chamber via the nozzle by driving the pressure generating unit, during a period in which the liquid is not ejected from the nozzle.

摘要： A liquid ejection head includes a flow path substrate, a first plate having a nozzle, and a second plate. A flow path substrate includes a first communication path which passes through a flow path substrate in a thickness direction and has an opening on each of a first plate side and a second plate side, and a second communication path communicating with an opening on a first plate side of a first communication path at a first plate side and extending on the second plate side. A pressure chamber communicating with a first communication path and a first flow path through which a liquid flows into a pressure chamber are formed by a part of a second plate and a part of a flow path substrate.

摘要： A liquid container into which ink is injected comprises a liquid container body configured to contain a liquid therein; and a liquid supply assembly located on one end portion of the liquid container body. The liquid supply assembly has a liquid supply port provided to supply the liquid to a liquid consuming apparatus. The liquid supply port is formed to face in an intersecting direction that intersects with the direction of gravity and to be protruded in the intersecting direction from the one end portion when the liquid supply assembly is supported such as to be located above the liquid container body in the direction of gravity. A liquid injection member is inserted into the liquid supply port, and the liquid is injected into the liquid container body. The liquid supply port is then arranged to be protruded in the intersecting direction, and the liquid injection member is detached from the liquid supply port.

摘要： A technique that can restrict an arrangement angle of a liquid cartridge before use in a packaged state is provided. A packaging body 10 of a cartridge 100 includes a bag-shaped member 20 and a box-shaped member 30. The bag-shaped member 20 houses the cartridge 100. The box-shaped member 30 houses the cartridge 100 housed in the bag-shaped member 20. The cartridge 100 has an atmosphere introduction hole 125b capable of introducing the atmosphere to the inside, and the box-shaped member 30 has a first side wall portion 36 located at a position opposed to the atmosphere introduction hole 125b. The first side wall portion 36 has a first and second outer wall surfaces 36a and 36b that intersect each other to constitute a projecting portion that projects outward. A third end side portion 23 of the bag-shaped member 20 is housed at a corner portion between the first and second outer wall surfaces 36a and 36b.
