Abstract
A suction fan of a sheet feeder sucks in air through a sheet feeding belt to generate flotation air. The suction fan uses the flotation air to attract set sheets by suction. A belt motor rotates a sheet feeding belt and feeds out a sheet of the set sheets. An interval measurer measures a sheet-to-sheet interval when the suction fan is attracting the sheet by suction. Based on an output of the interval measurer, a controller recognizes the sheet-to-sheet interval. Based on the recognized sheet-to-sheet interval, the controller adjusts a flow rate of the flotation air.
