Zusammenfassung:	PURPOSE:To effectively anti-offset ink of a printing sheet with a simple structure by providing an air nozzle for spraying the air laterally to the sheets to be stacked on a delivery base of a sheet printer. CONSTITUTION:An air nozzle 11 provided near an upper part of printing sheets (s) stacked on a delivered sheet base 10 of a sheet discharger having an ink anti-offset device sprays the air. As a result, the sheets (s) are raised at a recess S0 to suppress its waviness, dropped to be stacked without rubbing by a differential motion of a jogger, own weight of the sheets (s), and ink is dried by the sprayed air, and hence ink off-set is eliminated. In this case, if dry accelerator of ink such as ozone, etc., is mixed with the air, drying of the ink is expedited to further prevent the ink off-set.
