发明名称 Liquid ejecting apparatus
摘要 A liquid ejecting apparatus includes a liquid flow path connecting a liquid containing unit that contains a liquid to a liquid ejecting unit that ejects the liquid. The liquid flow path includes a supply flow path which connects the liquid containing unit to the liquid ejecting unit and a return flow path which connects the liquid ejecting unit to the liquid containing unit. When the liquid is not ejected by the liquid ejecting unit, the liquid contained in the liquid containing unit is circulated between the liquid containing unit and the liquid flow path by allowing the liquid to flow in order of the supply flow path, the liquid ejecting unit, and the return flow path. When the liquid is ejected, the liquid contained in the liquid containing unit is supplied to the common liquid chamber via both of the supply flow path and the return flow path.

主权项 1. A liquid ejecting apparatus comprising: a liquid containing unit that contains a liquid; a liquid ejecting unit that ejects the liquid; a liquid flow path that connects the liquid containing unit to the liquid ejecting unit; and a flowing mechanism that flows the liquid in the liquid flow path, wherein the liquid ejecting unit includes a plurality of nozzles, and a common liquid chamber which stores the liquid supplied from the liquid flow path, the common liquid chamber communicating with the nozzles, wherein the liquid flow path includes a liquid storage chamber which includes an inlet and an outlet and a wall formed with a flexible member and communicates with the common liquid chamber, a supply flow path which connects the liquid containing unit to the inlet, and a return flow path which connects the outlet to the liquid containing unit and in which the regulation portion is installed, wherein when the liquid is not ejected from the nozzles to a medium, the liquid is circulated between the liquid containing unit and the liquid flow path by driving of the flowing mechanism, and wherein when the liquid is ejected from the nozzles, the liquid contained in the liquid containing unit is allowed to flow to the liquid storage chamber via both of the supply flow path and the return flow path.
