Abstract

PURPOSE:To prevent the abnormal deformation caused by jamming or the like by selecting the quality of the material of intermediate rollers so that friction factors between intermediate rollers and separation rollers may be lower than those between feed rollers and a paper sheet and higher than that between paper sheets. CONSTITUTION:Separation rollers 21a and 21b are pressed to feed rollers 18a and 18b. The quality of the material of rollers 23a and 23b is selected so that friction factors between rollers 21a and 21b and intermediate rollers 23a and 23b in contact with the rollers 21a and 21b may be lower than those between rollers 18a and 18b and a paper sheet 1 and higher than that between paper sheets 1. When rollers 18a and 18b in a paper-conveyance direction F and rollers 23a and 23b in a direction G are respectively rotated, rollers 21 and 21b are rotated in a direction H. When two or more paper sheets 1 are bitten in a paper-sheet separation part composed of rollers 18a and 18b and rollers 21a and 21b, slipping is given between paper sheets 1, and rollers 21a and 21b are rotated in a direction I to push back paper sheets except the lowest one.
