LIQUID DISCHARGE APPARATUS AND METHOD

摘要

Disclosed is a liquid discharge apparatus that is capable of setting a proper deflection amount for deflecting an ink discharge direction even when the distance between the ink discharge surface and the ink landing surface of print paper varies. The liquid discharge apparatus includes a head (11) in which a plurality of nozzle-incorporated ink discharge sections are arrayed, discharge direction deflection means for deflecting the discharge direction of an ink discharged from a nozzle of each ink discharge section in the direction of ink discharge section arrangement, distance detection means for detecting the distance (L1) and (L2) between the ink discharge surface of the head (11) and the ink landing surface of print paper (P1) and (P2), and discharge deflection amount determination means for determining the ink discharge deflection amount (discharge angle alpha and beta ) to be provided by the discharge direction deflection means in accordance with the results of detection by the distance detection means.
