Abstract

An apparatus for separating documents from one another includes two spaced-apart rollers which define a gap therebetween. The rollers rotate so that the surfaces which face one another move in opposite directions. One of the rollers serves to transport a document in the conveying direction, while the second countermoving roller serves to hold back any additional document which has been fed on top of the first document. The second roller is mounted so as to be pivotable, so that the gap between the rollers can be adjusted in accordance with the document conveyed through the gap. A guide roller serves to maintain the gap between the rollers. A storage container for the documents has movable rearward and bottom walls, wherein the rearward wall is biased by a tension spring so as to exert an essentially constant pressure on the stack of documents.
