DEVICE AND METHOD TO UNIFORMLY AND EQUALLY SUPPLY INK TO BOTH ENDS OF LIQUID DROPLET GENERATOR

摘要

PROBLEM TO BE SOLVED: To suppress a turbulent flow in a liquid droplet generator even if a print head becomes long or the amount of liquid droplet generated is increased. SOLUTION: A liquid droplet generator is related to an inkjet printer, and the liquid droplet generator is composed of many fluid ports for the liquid droplet generator. At least one of the many fluid ports functions as a one-way entrance port when liquid is supplied to the liquid droplet generator. At least one of the many fluid ports is of a bi-directional type, and functions as an exit at the time of start and stop of the print head. It also functions as an additional ink exit port during an ordinary operation of the print head. Thereby, the flow rate at the entrance is reduced below the flow rate when a turbulent flow occurs.
