Abstract

PURPOSE: To prevent liquid from sticking around nozzles and causing clogging by providing grooves around the nozzle of a multinozzle plate for liquid injection, making the edge parts at the nozzle tips into knife edges or making the flat parts extremely small.
CONSTITUTION: Nozzles 3 which inject liquid such as ink are formed to a multinozzle plate 6 which is supported by a nozzle plate holding plate 4. High-frequency vibrations are given to the ink in a liquid chamber structural body 1 so that the ink is injected as ink drops from the nozzles 3. At this time, grooves 7 are provided around the nozzles 3 to make the edge parts at the nozzle tips into knife edges or make the flat parts extremely small, so that the spreading of the root of the injected ink 5a is prevented and the amount sticking around the nozzle 3 is made extremely small. Since the drooping of the ink occuring when the injection of the ink is stopped is recovered into a recovery system through the grooves 7, 8, the occurrence of clogging and unstability of the injection direction of the ink are prevented.
