Abstract:
A droplet discharge device includes a functional liquid droplet discharge head and a functional liquid tank. The functional liquid tank includes a tank body, a liquid column pipe and a liquid level detection mechanism. The tank body is configured and arranged to retain the functional liquid to be supplied to the functional liquid droplet discharge head. The liquid column pipe communicates with the tank body. The liquid level detection mechanism is configured and arranged to detect a liquid level of the functional liquid retained in the liquid column pipe. The functional liquid tank is configured and arranged to allow supplying and ventilating of gas.
