Abstract
A liquid ejection device ejects liquid droplets from a liquid ejection head. The liquid ejection device includes a liquid feeding member that feeds liquid to the liquid ejection head. The liquid feeding member is connected to a liquid ejection head to feed liquid to a common liquid chamber of the liquid ejection head, which liquid ejection head includes the common liquid chamber that supplies the liquid to plural individual liquid chambers communicating with plural nozzles that eject liquid droplets. The liquid feeding member includes a liquid circulation path through which the liquid circulates in a direction parallel to a direction in which the nozzles of the liquid ejection head are aligned.
Claims16
A liquid ejection device that ejects liquid droplets from a liquid ejection head, the liquid ejection device comprising:
- a liquid feeding member that feeds liquid to the liquid ejection head, the liquid feeding member being connected to a liquid ejection head to feed liquid to a common liquid chamber of the liquid ejection head, which liquid ejection head includes the common liquid chamber that supplies the liquid to plural individual liquid chambers communicating with plural nozzles that eject liquid droplets, the liquid feeding member comprising:
- a liquid circulation path through which the liquid circulates in a direction parallel to a direction in which the nozzles of the liquid ejection head are aligned;
- wherein a feed port through which the liquid is supplied to the liquid circulation path and a discharge port through which the liquid is discharged from the liquid circulation path are disposed at opposing longitudinal ends of the liquid circulation path;
- a communication opening communicating with the common liquid chamber being disposed at the side of the common liquid chamber in the liquid circulation path;
- and
- the communication opening having a smaller width than a width of the liquid circulation path.
A liquid ejection device that ejects liquid droplets from a liquid ejection head, the liquid ejection device comprising:
- a liquid feeding member that feeds liquid to the liquid ejection head, the liquid feeding member being connected to a liquid ejection head to feed liquid to a common liquid chamber of the liquid ejection head, which liquid ejection head includes the common liquid chamber that supplies the liquid to plural individual liquid chambers communicating with plural nozzles that eject liquid droplets, the liquid feeding member comprising:
- a liquid circulation path through which the liquid circulates in a direction parallel to a direction in which the nozzles of the liquid ejection head are aligned;
- wherein a feed port through which the liquid is supplied to the liquid circulation path and a discharge port through which the liquid is discharged from the liquid circulation path are disposed at opposing longitudinal ends of the liquid circulation path;
- a communication opening communicating with the common liquid chamber being disposed at the side of the common liquid chamber in the liquid circulation path;
- and
- plural ribs are disposed around the communication opening.
A liquid ejection device that ejects liquid droplets from plural liquid ejection heads, the liquid ejection device comprising:
- the plural liquid ejection heads elongated in a longitudinal direction of a liquid ejection member and arranged longitudially offset from one another in a direction orthogonal to the longitudinal direction;
- the liquid feeding member connected to the plural liquid ejection heads to feed liquid to common liquid chambers of the liquid ejection heads, each of which liquid ejection heads includes the common liquid chamber from which the liquid is supplied to plural individual liquid chambers communicating with plural nozzles that eject liquid droplets, the liquid feeding member comprising:
- a liquid passage through which the liquid passes in a direction parallel to a direction in which the nozzles of each of the liquid ejection heads are aligned;
- wherein a feed port through which the liquid is supplied to the liquid passage and a discharge port through which the liquid is discharged from the liquid passage are provided in the liquid passage;
- and
- the liquid passage having a greater cross-sectional area at portions connected to the liquid ejection heads than at portions between the adjacent common liquid chambers.
