Abstract
A copying device having an automatic document feed has a bar which extends across a substantial portion of the document path out of alignment with the image scanning portion of the platen. This bar is of a magnetically receptive material so that it is responsive to movement of a magnet which is located on the opposite side of the document-moving belt. When a document is being moved by the belt into the document exposing region, the document stop bar rests on the platen or at the edge of the platen so that the leading edge of the document butts against it. When the document is to be ejected, the magnet is moved, raising the document stop bar out of the document path; a roller which is adjacent the belt and the document being copied can now be rotated and eject the document below the document stop. In addition to lifting the magnet and therefore the document stop bar, the magnet moves slightly forward along the document path so that the edge of the document is removed from the document stop bar. In this way, the document does not bind against the stop bar and the document may be easily ejected.
