PROBLEM TO BE SOLVED: To improve separation and conveyance performance even in a film-like sheet made of thin paper which has low rigidity and easiness of electrification.SOLUTION: A sheet supply device includes: a plurality of side edge blowing parts which blow air from both side edges along the conveyance direction of a piled sheet; a side edge ion generation part which makes ion generate in each path of air that is blown from the plurality of side edge blowing parts; and an ion polarity control part which controls the side edge ion generation part so that ion polarities of the air that is blown from one side edge blowing part and the other side edge blowing part opposed to the one side edge blowing part, among the plurality of side edge blowing parts differ respectively according to a prescribed pattern.SELECTED DRAWING: Figure 12 【課題】低剛性および帯電しやすい薄紙のフィルム状のシートであっても、分離および搬送性の向上を図ること。【解決手段】積載されたシートの搬送方向に沿った両側端からエアを噴き付ける複数の側端噴付部と、複数の側端噴付部から噴き付けるエアの経路それぞれにイオンを発生させる側端イオン発生部と、複数の側端噴付部のうち、一方の側端噴付部と当該側端噴付部に対向する他方の側端噴付部とから噴き付ける上記エアのイオン極性を、所定のパターンに従ってそれぞれ異なるように上記側端イオン発生部を制御するイオン極性制御部と、を有する。【選択図】図１２
