A LIQUID DROPLET EJECTING HEAD, A WRITING INSTRUMENT COMPRISING SUCH A HEAD, AND A METHOD OF EJECTING LIQUID DROPLETS FROM SAME

摘要

A liquid droplet ejecting head (100) designed to be mounted in a liquid ejecting instrument(1). The liquid droplet ejecting head contains actuating chambers (105) with inlets to be connected to liquid supply chambers (106) a nd an outlet (108) connected to an ejection nozzle (99). The actuating chambers also contain actuating means (120) for creating a pulse wave in the liquid contained therein when activated by energy received from a control device. T he outlets (108) of the actuating chambers are linked to a single common ejecti on nozzle (99) through which a droplet is ejected.
