Zusammenfassung:To provide a liquid discharge device comprising a liquid discharge head provided oppositely to an outer peripheral surface of a drum, which can maintain printing quality while maintaining productivity.SOLUTION: A liquid discharge device 20 comprises: a drum 2 rotating while winding a sheet around it; a liquid receiver 21 provided on an outer peripheral surface of the drum; and a liquid discharge head 3 facing the outer peripheral surface of the drum and comprising a plurality of nozzles. In a drum width direction that is a direction orthogonal to a rotation direction of the drum on the outer peripheral surface of the drum, the nozzles facing the sheet execute a flushing operation on the sheet. In the drum width direction, the nozzles not facing the sheet execute the flushing operation on the liquid receiver, when facing the liquid receiver by the rotation of the drum, regardless of presence/no presence of discharge of the nozzles facing the sheet.SELECTED DRAWING: Figure 8 【課題】生産性を保ちつつ印刷品質を維持できる、ドラムの外周面に対向して設けられた液体吐出ヘッドを備える液体吐出装置の提供。【解決手段】シートを巻き付けて回転するドラム2と、前記ドラムの外周面に設けられた液体受け21と、前記ドラムの前記外周面と対向し、複数のノズルを備える液体吐出ヘッド3と、を備え、前記ドラムの前記外周面上で前記ドラムの回転方向と直交する方向であるドラム幅方向において前記シートと対向するノズルは、シート上にフラッシング動作を実施し、前記ドラム幅方向において前記シートと対向しないノズルは、前記ドラムの回転により前記液体受けに対向するときに、前記シートと対向するノズルの吐出の有無に依らず前記液体受けにフラッシング動作を実施する、液体吐出装置20。【選択図】図8
