SHEET SUPPLY DEVICE

To feed out a loaded uppermost sheet one by one.SOLUTION: This device comprises: a floating air blow-out port 29b for blowing-out air from the side of a loaded uppermost paper P (sheet); a flow regulating member 35 which extends from the floating air blow-out port 29b to the upper part of an edge part of the loaded uppermost paper P to generate airflow by the air blown out from the floating air blow-out port 29b along an upper surface of the loaded uppermost paper P; a separation air blow-out port 29c for blowing-out the air from the downstream side in a conveyance direction of the paper P to the space between the uppermost paper P floated to the flow regulating member 35 by the generated airflow and a second paper P, and a separation air blow-out port 29a for blowing-out the air from the side orthogonal to the conveyance direction; a shutter 31d for switching between blow-out and stop of the air by the floating air blow-out port; and a control part 9 which functions as air control means for controlling it.SELECTED DRAWING: Figure 2 【課題】積載された最上部のシートを１枚ずつ送り出す。【解決手段】積載された最上位の用紙Ｐ（シート）の側方から空気を吹き出す浮上エア吹出口２９ｂと、浮上エア吹出口２９ｂから積載された最上位の用紙Ｐの縁部の上方に延出し、浮上エア吹出口２９ｂから吹き出された空気による空気流を積載された最上位の用紙Ｐの上面に沿って発生させる整流部材３５と、発生した空気流により整流部材３５まで浮上した最上位の用紙Ｐと２番目の用紙Ｐとの間に、用紙Ｐの搬送方向下流側から空気を吹き出す分離エア吹出口２９ｃ、および搬送方向と直交する側方から空気を吹き出す分離エア吹出口２９ａと、浮上エア吹出口による空気の吹き出しまたは停止を切り替えるシャッター３１ｄと、これを制御するエア制御手段として機能する制御部９とを備える。【選択図】図２
