<p>Air flows 61 SIMILAR 64 from an air flow forming means 58 are jetted to near the downstream end of a plurality of sheets 30 stacked on a laying plate 31,136 so as to separate either a uppermost sheet 30b or a bottommost sheet 30a from the remaining sheets 30. The uppermost sheet 30b or the bottommost sheet 30a is vacuum attracted to a vacuum attracting area VA defined in a feeding belt 47 by a vacuum attracting box 55. Based on the size of the sheet 30, the open suction area A uncovered by the stacked sheets 30 in the vacuum attracting area VA is controlled, thereby enabling the feeding belt 47 to control the power of suction thereof to the sheets 30. Accordingly, a multiple feeding of the sheets 30 can be prevented due to an excessive power of suction. <IMAGE></p> |
