Abstract

When the fluid of the ink jet printer flows into the ejector(35) introduced by the guide hump(31)(32), a pressure difference occurs between the connecting hole(45) and the discharging hole(42), due to the change of the section of the 1st and the 2nd passages(30)(40). This pressure difference works on the electro viscosity fluid(80) in the storage(70) thru the connecting holes(45)(55)(65). Therefore the electro viscosity fluid(80) is provided to the space part(90) thru the injection part(62). In case the print signal is provided to the 1st and 2nd electrodes(41)(61), the viscosity of the electro viscosity fluid changes in accordance with the potential and by the difference of the viscosity pressure, the amount of the ejection of the fluid(80) is determined. The fluid(80) is ejected thru the ejector(35) and records a picture on the paper.
