PURPOSE:To facilitate changing of a picture quality of printing speed by providing a plurality of discharge units and orifices against plural different faces. CONSTITUTION:An array of plural orifices 2 are provided on four faces of a recording head 1 and any selected face is directed toward an object to be recorded by turning a shaft 4 to discharge a recording liquid from the orifice 2 on that face. It is possible to change the quality of a recorded image by changing the density of the orifice 2 on each one of the four faces and also change the recording speed by changing a frequency to be applied to an energy generating element 5 located at the orifice of the four faces. |
