PROBLEM TO BE SOLVED: To reduce the number of pumps for supplying ink to storage tanks to simplify pipes.SOLUTION: An inkjet recording device 1 includes: an upper head 2 and an upper storage tank 3; a first sensor 8 which detects a liquid surface of the upper storage tank; a lower head 13 and a lower storage tank 13; a second sensor 18 which detects a liquid surface of the lower storage tank; an ink tank 20 which supplies ink to the upper storage tank; an opening/closing control valve 25 provided at a supply pipe 21 connecting the ink tank with the upper storage tank; and a connection pipe 26 connecting the upper storage tank with the lower storage tank. The opening/closing control valve is opened or closed on the basis of detection signals of the sensors, the ink is supplied from the tank to the upper storage tank, and the ink is supplied from the upper storage tank to the lower storage tank through the connection pipe.SELECTED DRAWING: Figure 1 【課題】貯留タンクにインクを供給するポンプ数を減らし配管を簡素化する。【解決手段】インクジェット記録装置１は、上部ヘッド２及び上部貯留タンク３と、上部貯留タンクの液面を検出する第１センサ８と、下部ヘッド１３及び下部貯留タンク１３と、下部貯留タンクの液面を検出する第２センサ１８と、上部貯留タンクにインクを供給するインクタンク２０と、インクタンクと上部貯留タンクを結ぶ供給管２１に設けた開閉制御弁２５と、上部貯留タンクと下部貯留タンクの連絡管２６を有する。センサの検知信号に基づいて開閉制御弁を開閉し、タンクから上部貯留タンクにインクを供給し、上部貯留タンクから連絡管を経て下部貯留管にインクを供給する。【選択図】図１
