PROBLEM TO BE SOLVED: To provide a sheet feeder that feeds stacked sheets on a one-by-one basis and that reliably prevents poor sheet feeding and double feeding from being caused by blocking of the sheets and the like, with a simple configuration.SOLUTION: A sheet feeder includes an air supply part 23 that sprays air on back ends, in a feed direction of a sheet feeding part 21, of sheets 41 stacked on the sheet feeding part 21 movable upward and downward. The state of making upside and downside sheets abut on the sheet 41 to be fed is eliminated, and the sheets 41 are fed out on a one-by-one basis from the sheet feeding part 21 by a sheet feeding roller 52 and a paper feed roller, which are feeding conveyance parts. |
