Abstract

PURPOSE: To make the ejecting direction of liquid drops straight and eliminate the scattering of the ejection direction, by treating the end face of the nozzle head of an ink jet printer to make the interfacial properties of the end face uniform.
CONSTITUTION: A nozzle head 1 comprises conduit parts 4 for ejecting liquid drops or ink particles and pressure chambers 3 provided in the halfway sections of the conduit parts. The pressure chambers communicate with a common ink reservoir 6 through the conduit parts 4 and fluid diodes 5. The volume of each pressure chamber 3 is changed by an electric pulse to eject the liquid drops from a nozzle port 2 which communicates with the pressure chamber 3. A base made of Pyrex glass is electrostatically conjoined to the end face of the nozzle head on the nozzle ports 2. A thin film of silicon dioxide is provided on the base by evaporation or sputtering to produce uniform interfacial properties on the end face. This results in moving the ejected ink particles straight and improving their flying property.
