Patent ID: 8573759

Claim:
A droplet discharging apparatus for discharging droplets of a recording fluid, the droplet discharging apparatus comprising: a tank; a negative pressure portion formed in the tank; a pressurizing portion formed in the tank and connected to the negative pressure portion via a communicating channel formed at a lower part of the tank, a longitudinal direction of the pressurizing portion being disposed vertically; a valve configured to open or close the communicating channel; a bubble storing area configured to separate and store bubbles of the recording fluid, the bubble storing area being located above the communicating channel in the pressurizing portion; and a supply opening for supplying the recording fluid into the pressurizing portion from the outside, wherein each of the pressurizing portion and the negative pressure portion has a continuous space that extends from a lower end of the tank to an upper end of the tank, a separation wall that extends from the lower end of the tank to the upper end of the tank is disposed at a central portion and between the pressurizing portion and the negative pressure portion to divide the pressurizing portion and the negative pressure portion, the communicating channel is formed at the lower part of the separation wall to penetrate through the separation wall laterally, and the valve opens and closes the communicating channel, and wherein the recording fluid flows from the pressurizing portion to the negative pressure portion via the communicating channel and the valve, the pressurizing portion is disposed upstream of the valve, the negative pressure portion is disposed downstream of the valve, and the supply opening is disposed under the communicating channel connected to the valve.
