ABSTRACT:
A paper feeding device for a copier or the like enables reliable feeding of thicker paper products by providing at least one pivotable holding arm carrying a paper pressing member and a contacted adjacent elastic member. The feeding of the topmost paper effects deformation of the elastic member until a gap is formed sufficient to pass one sheet, following which the sheet is advanced. Further sheets are prevented from being passed together with the first sheet by the size of the gap and frictional resistance. The elastic member may be formed of an elastomer such as natural rubber and may include an upper hollow defining a contact surface of arcuate shape.
