<p>PURPOSE:To reliably separate and feed a sheet material, by providing a control means adapted to reversely rotate a separating member when the front end of the sheet material passes through a nip portion between a feeding member and the separating member. CONSTITUTION:When a start command is generated, a feeding roller 109 is lowered to feed a document P to a separating portion 132. Some fed sheets of the document P are nipped between rollers 101 and 103, and are fed forwardly. At this time, the separating roller 103 is rotated by a torque of the upper roller 101 in the direction of A, that is, in the same direction as of the upper roller 101. At this time, a clutch cl1 is on, and a clutch cl2 is off. When one to several sheets of papers fed are detected by a sensor 130, the rotation of the separating roller 103 is changed into the direction of B, that is, the rotation reversed to that of the upper roller 101, by the on-operation of the clutch cl2. Accordingly, the some nipped papers are forced back sequentially from the lowest paper, and only one sheet of paper if left.</p> |
