Abstract
A circulation device according to an aspect includes a storage unit for storing liquid and a liquid droplet discharge unit for discharging liquid, and controls circulation of liquid flowing through a channel communicating the storage unit and the liquid droplet discharge unit with each other. Such a circulation device includes a robotic portion, a first pressure portion, a second pressure portion, a first valve portion, and a second valve portion. The robotic portion is mounted with the liquid droplet discharge unit. The first pressure portion feeds the liquid stored in the storage unit to the liquid droplet discharge unit through a first channel communicating the storage unit and the liquid droplet discharge unit with each other. The second pressure portion feeds the liquid recovered in the liquid droplet discharge unit to the storage unit through a second channel communicating the storage unit and the liquid droplet discharge unit with each other. The first valve portion is interposed between the first pressure portion and the liquid droplet discharge unit. The second valve portion is interposed between the second pressure portion and the liquid droplet discharge unit.
