PROBLEM TO BE SOLVED: To suppress a problem such as the overlapped feeding in a normal sheet, to prevent generation of a wrinkle in a thin sheet, and to prevent a feeding failure in the case of an extremely thick sheet such as an envelope or a private postcard. SOLUTION: In this paper feeder, a separating means 123 is provided on the upstream side of a main separation means 122 having a main separation member 126 contacting with a paper feeding roller 120. The separating means 123 has a base member 132 slidably supported by a bracket 131, a separating plate 130 held on the upper face of the base member 132 and pressed to the peripheral face of the paper feeding roller 120 by a prescribed pressure, and a spring 133 as an energizing means pressing the separating plate 130 to the paper feeding roller 120 through the base member 132, or the like. A gap G is formed between the separating plate 130 and the main separation means 122 over a movable range of the separating plate 130.
