Abstract

An automatic sheet feeding apparatus for feeding sheets on a stacker one by one, includes a separation device having a sheet convey member for conveying a separated sheet and a double feed prevention member which is brought into tight contact with or separated from the convey member, and a sheet stop member for preventing movement of nonseparated sheets along a convey direction. When the separation device is in tight contact with the sheet during a separation operation, the sheet stop member is located in a first position where the sheet stop member does not prevent the separation operation. When the separation device is released and the sheet is conveyed, the sheet stop member is moved to a second position where the sheet stop member abuts against leading ends of sheets except for a sheet to be fed, thereby preventing movement of the sheets except for the sheet to be fed.
