Summary:To smoothly perform position control of two belts in a sandwiched conveyance method for conveying a sheet-shaped conveyed object in a gap between one pair of endless belts.SOLUTION: A cooling apparatus 9 as an example of a sheet conveyance apparatus includes a control unit 43 that performs control to tilt a first steering roller 55c or a second steering controller 57c based on outputs of a belt position detection sensors 41, 42 so as to stop a movement in a width direction generated in a first belt 56 or a second belt 59. The control unit 43 performs cooperative control that controls the first steering roller 55c or the second steering roller 57c so that a relative speed of the first belt 56 and the second belt 59 in the width direction becomes a predetermined value or less.SELECTED DRAWING: Figure 8 【課題】一対の無端状ベルトの間隙にてシート状の搬送物を搬送する挟持搬送方式において2つのベルトの位置制御を円滑に実施する。【解決手段】シート搬送装置の一例としての冷却装置9は、第1ベルト56または第2ベルト59に発生した幅方向の寄り移動を停止させるように、ベルト位置検出センサ41、42の出力に基づいて第1ステアリングローラ55cまたは第2ステアリングローラ57cを傾動させる制御を行う制御部43を備える。制御部43は、第1ベルト56と第2ベルト59との幅方向の相対速度が所定値以下となるように第1ステアリングローラ55cまたは第2ステアリングローラ57cを制御する協調制御を実施する。【選択図】図8
