Embodiment Construction

[0015] Hereinafter, embodiments of the liquid ejecting device will be described with reference to the drawings. The liquid ejecting device is, for example, an inkjet printer that performs recording (printing) by ejecting ink, which is an example of a liquid, onto a medium such as paper.

[0016] Such as figure 1 As shown, the liquid ejecting device 11 of this embodiment is, for example, a large format printer (Large Format Printer (LFP)) that performs printing on a medium S of a relatively large size such as A0 size or B0 size according to JIS standards.

[0017] The liquid ejecting device 11 includes a housing, support legs 13 that support the housing 12 , and a liquid supply device 14 disposed on the housing 12 . The liquid supply device 14 includes: one or more (four in this embodiment) storage body holders 16 capable of attaching a liquid storage body 20 for storing liquid; side of the axis of rotation 17 . The container holder 16 holds the attached liquid container 20 ...

Abstract

The present invention provides a liquid ejecting apparatus capable of prolonging the driving life of a pressure feeding mechanism and enforcing stable liquid ejection and a liquid supply method thereof. The liquid ejecting apparatus (11) includes a liquid ejecting portion (33) that has a nozzle (36) and performs a recording process by ejecting liquid from the nozzle toward a medium (S), a supply flow path (37) that is provided to be able to cause the liquid that is accommodated in a liquid accommodating body (20) to flow toward the liquid ejecting portion (33), and a pressure feeding mechanism(38) that forcefully causes the liquid to flow from the liquid accommodating body (20) toward the liquid ejecting portion (33), and an accommodating body holding portion (16) that is capable of having the liquid accommodating body (20) mounted thereon and is disposed at a supply position at which it is possible to supply the liquid to the liquid ejecting portion (33) using a head with respect tothe nozzle (36) of the liquid that is accommodated in the mounted liquid accommodating body (20).

Description

[0001] The entire disclosure of Japanese Patent Application No. 2016-158437 filed on August 12, 2016 is incorporated herein by reference in its entirety. technical field [0002] The present invention relates to a liquid ejecting device such as a printer. Background technique [0003] Conventionally, there is a liquid ejection device that drives a diaphragm pump provided in the middle of a supply channel to supply liquid to a liquid ejection head that ejects liquid (for example, Patent Document 1). [0004] In the liquid ejection device described above, it is necessary to frequently drive the pump to maintain the internal pressure of the supply channel at a pressure required for sufficient liquid supply. Furthermore, when the driving time of the pump becomes longer, there is a problem that the lifetime of the pump becomes shorter. [0005] Patent Document 1: Japanese Patent Laid-Open No. 2009-160912 Contents of the invention [0006] The present invention has been made i...
