されたことを特徴とする給紙装置。A pickup roller that presses against the top surface of the stacked J paper bundle and rotates in the paper feeding direction, a feed roller that is downstream of the stack and rotates in the paper feeding direction, and a friction separation that presses against this across the paper path. In a paper feeding device that separates double feeding and feeds sheets one by one, the friction separation member has two or more friction members having different friction coefficients on the circumferential surface of the roller in the circumferential direction. A paper feeding device characterized in that it is configured with a low friction surface interposed therebetween and configured as a roller that is not driven by the feed roller.
