Abstract

PURPOSE:To prevent the mutual collision of ink drops while flying and deviation of their adhering points and maintain good recording quality by defining the interval between multiplex type orifices at a specific value. CONSTITUTION:In arranging a plurality of exhaust orifices 16 in a high density to the utmost, the distance between the centers of adjacent orifices is represented by l and the interval between the peripheral edges of both orifices 16 and 16 is represented by r, and orifices 16 are arranged so that the value of r/(l-r) becomes 1/3 or more. Even when ink drops are exhausted simultaneously from respective orifices 16..., collision of ink drops and their incorporation do not almost occur. With too much value of r/(l-r), the interval between the orifices is windened and the resolution on the recorded surface is lowered. Therefore, the value of r/(l-r) should be limited to about 20.
