Abstract
The present invention provides a sheet feeder including a stack tray on which the sheets are stacked, a feeding mechanism that separates and feeds one by one the sheets on the stack tray, a blowing mechanism that blows a predetermined amount of air against the sheets on the stack tray. An operation of the feeding mechanism and an amount of air to be blown by the blowing mechanism are controlled in association with each other, so that it is possible to prevent double-feeding of the sheets and a feeding failure, thereby achieving reliable sheet feeding.
