Abstract

PURPOSE:To prevent jamming and avoid deformations in pictures by providing the paper-covering route of a duplicating machine or the like with a means to detect the overlapped feeding of papers and a separating means to separate one of overlapped papers for sending to a fixed part and stop remained papers on the coveying route. CONSTITUTION:An overlapped feeding separation roller is constructed of a drive roller 36 to be rotated in a direction F and a driven roller 36' to be pushed thereby by a fixed pressure for rotation. When two papers are supplied between these rollers, since frictional rollers between the roller 36 and an upper paper and between the roller 36' and an under paper are made greater than the frictional force between the two papers, upper and under, the driven roller 36' cannot be rotated by the rotational force of the drive roller 36, and only the upper paper on the side of the roller 36 is conveyed as the under paper is stopped by the roller 36'. meanwhile, a disk 156 is provided with a plurality of perforations to be interlocked with the driven roller 36', and as it is rotated, pulse signals are issued from a photosensor 157. When overlapped feeding occurs, it is detected on the basis of the stoppage the disk 157 caused by the stoppage of the driven roller 36'.
