    • A sheet feeding apparatus capable of obtaining a sufficient conveying force for pulling back double-fed overlapping sheets to a stacking tray side. A sheet feeding member feeds sheets incoming from a stacking tray which stacks the sheets into a conveying pass. A separating member separates the sheets fed to the conveying pass by the sheet feeding member one by one. A double feed detection sensor generates an output for detecting double feed of sheets fed to the conveying pass. A rotatable member contacts the fed sheet. A driving unit rotationally drives at least the rotatable member in a rotational direction for reverse feeding of sheets. A control unit controls the driving unit when the double feed of sheets is detected based on the output of the double feed detection sensor, such that the rotatable member is rotationally driven in the rotational direction for reverse feeding of sheets.
    • 一种能够获得足够的输送力的片材进给装置,用于将双重重叠的片材拉回到堆叠托盘侧。 片材进给构件将从堆叠托盘进入的片材进给,将片材堆叠成输送路径。 分离构件将通过片材进给构件一个一个地输送到输送通道的片材分离。 双进给检测传感器产生用于检测馈送到输送通道的纸张的双重进给的输出。 可旋转构件接触进给的片材。 驱动单元沿旋转方向至少旋转地驱动旋转构件以反向进给片材。 当基于双进给检测传感器的输出检测到纸张的双重进给时,控制单元控制驱动单元,使得可旋转构件在旋转方向上被旋转地驱动以反向进给纸张。
