ABSTRACT:
Recording papers stacked up on a tray are conveyed as being attracted in vacuum by the conveying belt located above or beneath. To convey the recording papers one by one, air flow is blown to the front edge of the recording papers to separate. Accordingly, plural nozzles are disposed in the widthwise direction of the recording paper, and the air flows from the nozzles are directed to converge at the upstream side in the conveying direction front the front edges of the recording papers. By setting this converging position near the both ends in the widthwise direction of the recording papers, the recording papers may be separated securely and stably.
