PROBLEM TO BE SOLVED: To suppress the contamination of an image recording face of a discharged paper sheet when a large number of the paper sheets are stacked on a placing face, in an inkjet recording device from which the paper sheet recorded with an image is vigorously discharged to a stopper.SOLUTION: An inkjet recording device 1 comprises: a drying mechanism 2 for drying a paper sheet P formed with an image by a liquid ejection head 4; a discharge tray 11 on which the paper sheets P dried by the drying mechanism 2 are stacked; a motor M for discharging the paper sheet P dried by the drying mechanism 2 to the discharge tray 11; a stopper 15 for making the paper sheet P collide with and fall down to the discharge tray 11; a measurement means for measuring a stack thickness of the paper sheets P on the discharge tray 11; and a control means 80 for controlling the drying mechanism 2. When the stack thickness of the paper sheet measured by the measurement means is not thinner than a threshold, the control means 80 controls the drying mechanism 2 so that the stack thickness may increase a drying degree of the paper sheet P compared with the case that the stack thickness is thinner than the threshold. |
