Abstract
A sheet feeding apparatus includes first and second transport devices disposed at a transport guide with a distance in between for nipping and transporting a sheet, and a double feed detection device disposed between the first transport device and the second transport device for detecting a double feed of the sheet. A sheet end detection device is disposed at a downstream side of the first transport device for detecting a trailing end of the sheet, and a determination device is provided for determining the double feed based on a detection signal from the double feed detection device and a detection signal from the sheet end detection device.
