LIQUID EJECTING APPARATUS

摘要

A liquid storage unit for collecting a liquid supplied to an ejecting head is provided. The liquid is supplied to a plurality of ejecting heads via a pressure regulating valve, and the liquid is suctioned from the plurality of ejecting heads by a circulation pump, and then is discharged to the liquid storage unit. In this way, since the liquid is suctioned from each of the ejecting heads, the passage resistance is decreased, so that the ink can be appropriately circulated. In addition, since the ejecting head is supplied with the liquid at an appropriate pressure from the liquid storage unit via the pressure adjusting valve, the liquid can be appropriately ejected.

主权项

1. A liquid ejecting apparatus which supplies a liquid, which is received in a liquid container, to a plurality of ejecting heads, and ejects the liquid from ejecting nozzles of the ejecting heads, the liquid ejecting apparatus comprising:
a liquid storage unit which is provided at an upstream side of the plurality of ejecting heads, and stores the liquid supplied to the ejecting heads; a pressure regulating valve which is provided between the liquid storage unit and the plurality of ejecting heads, and opens a valve if a pressure of the liquid inside the ejecting heads is dropped to a predetermined pressure or less, so that the liquid received from the liquid storage unit side is supplied to the ejecting heads to regulate the pressure of the liquid inside the ejecting heads; and a circulation pump which suctions the liquid inside the ejecting heads from a liquid circulation port provided in the plurality of ejecting heads to discharge the liquid to the liquid storage unit, thereby circulating the liquid between the plurality of ejecting heads and the liquid storage unit.
