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) and 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. The outlets (108) of the actuating chambers are linked to a single common ejection nozzle (99) through which a droplet is ejected.
