Abstract

PURPOSE:To concentrate the ink jets from all ink heads at one printing point by blowing air to the ink jets from the ink heads thereby deflecting the flying dirctions of the ink jets. CONSTITUTION:When inks are simultaneously injected from respective ink heads, the ink jet from the magenta ink head M in the central position is printed to the printing point P on recording paper surface, but the ink jets from the yellow ink head Y and cyan ink head C on both sides are both projected in dotted line dirctions and are not printed onto the printing point P. Thereupon, air nozzles 2, 3 releasing air are provided on the respective outer sides of the ink heads on both end parts to blow air to the ink jets from the ink heads on both end parts and deflect the flying directions of the ink jets, whereby the ink jets from all the ink heads may be concentrated and printed to one printing point P.
