Abstract

PURPOSE:To prevent simultaneous supply conveyance of plural pieces of paper by detecting paper in the downstream from the line of expected contact between a conveyance belt and a separation belt and then retreating the paper except one piece of the lowest layer and subsequently advancing a desired paper after confirming the above retreat. CONSTITUTION:When paper on a paper stand 1 is detected by a detector 6, rollers 7, 8 and a conveyance belt 2 are put in operation to send the paper forward. A roller 9 is rotated following the paper at this time. When the paper is detected by a detector 10, since the belt 2 is stopped and a roller 9 is rotated backward, all the pieces of paper 21 except one piece in the lowest layer making contact with the belt 2 of large coefficient of friction are retreated from a line of expected contact between he belt 2 and the roller 9. At this time, the roller 12 also rotates backward and the paper 21 is retreated from the line of expected contact and stopped. Upon detection of this state by a detector 14 and subsequent confirmation that the paper 21 is a single piece, the belt 2 is restarted, and stopped when the paper 21 is completely conveyed into rollers 7, 8. When the extremity of the paper 21 sent out is detected by the detector 10, the belt 2 is operated, the roller 9 is freely rotated and the device recovers the next paper supply condition.
