Document Type and Number:
Japanese Patent JP7090435
Kind Code:
B2
Abstract:
To minimize the time delay of paper feeding and realizes smooth and quick paper feeding.SOLUTION: The sheet feeding device 1 includes a pair of floating air ejecting units 4 disposed on the downstream side in the sheet conveyance direction, and a separation air ejecting unit 5 disposed between the floating air ejecting units, in which the flying air and the separation air collide downstream in the sheet conveyance direction by the combination of the airflows of the flying air LA and the separation air SA and the arrangement of the floating air injection unit and the separation air injection unit. When specifying the type of paper, etc., each air volume of the floating air and separation air, and each arrangement of the floating air injection part and the separation air injection part are appropriately set according to the designated paper, downstream of the stacked sheets in the conveyance direction, the air velocity decreases, the pressure between the sheets increases, a separation force is effectively generated, and only the uppermost sheet that floats can be fed.SELECTED DRAWING: Figure 1
