LIQUID DISCHARGE DEVICE AND LIQUID DISCHARGE METHOD

To solve the problem in occurrence of an aggregate due to reaction of mist of ink and mist of reaction liquid when the mist of ink and the mist of reaction liquid adhere to a head for recording and a head for process liquid, and a possibility of the occurred aggregate clogging a nozzle of the head for recording or a nozzle of the head for process liquid.SOLUTION: A liquid discharge device which discharges liquid to a medium, comprises: a first discharge part that discharges first liquid; a second discharge part that discharges reaction liquid containing an aggregating agent for aggregating constituents contained in the first liquid; a placement part on which the first discharge part and the second discharge part are placed; and a driving part that moves the placement part in a first direction and a second direction which is the opposite direction to the first direction. The placement part on which the second discharge part is placed in the first direction of the first discharge part, comprises a first ventilation route through which air currents flow between the first discharge part and the second discharge part.SELECTED DRAWING: Figure 6 【課題】インクのミストと反応液のミストが、記録用ヘッドや処理液用ヘッドに付着すると、インクのミストと処理液ミストが反応して凝集物が発生する。発生した凝集物は、記録用ヘッドのノズル、もしくは処理液用ヘッドのノズルを詰まらせる可能性がある。【解決手段】液体吐出装置は、媒体に液体を吐出する液体吐出装置であって、第１液体を吐出する第１吐出部と、前記第１液体に含まれる成分を凝集させる凝集剤を含む反応液を吐出する第２吐出部と、前記第１吐出部と前記第２吐出部とを載置する載置部と、前記載置部を第１方向、及び前記第１方向と逆方向の第２方向に移動させる駆動部と、を有し、前記載置部は、前記第１吐出部の前記第１方向に前記第２吐出部を載置し、前記第１吐出部と前記第２吐出部との間に気流が流動する第１通気経路を備える。【選択図】図６
