ABSTRACT:
A paper sheet attracting system includes a suction air casing and a paper sheet attracting unit which has a bottom wall provided with a plurality of air intake openings. The paper sheet attracting unit is movably connected to the suction air casing via a flexible duct. The paper sheet attracting system further includes a pressure roller for depressing the paper sheets to be supplied. The paper sheet attracting unit is rotatable around the pressure roller, whereby the paper sheet attracting unit rotates, when driven by a drive motor, in a manner that a contacting point of the pressure roller and the paper sheets functions as a support point of the rotation. The attracting suction force created through the air intake openings is varied depending on the thickness of the paper sheet.
