摘要: A sheet feeder includes a delivery roller that contacts a sheet on a sheet supply tray to deliver the sheet; a first detection sensor disposed upstream of the delivery roller so as to detect the sheet on the sheet supply tray; and a second detection sensor disposed downstream of the delivery roller so as to detect a leading end portion of the sheet on the sheet supply tray. The delivery roller is activated in a state where the first detection sensor detects the sheet on the sheet supply tray while the second detection sensor does not detect the leading end portion of the sheet on the sheet supply tray. Thus, all the actually feedable sheets placed on the sheet supply tray can be fed, thereby reducing a sheet setting failure on the sheet supply tray, which reduces trouble of performing a re-set operation.
