Abstract

Apparatus includes a structure having a vertically disposed thin rectangular pocket into which the leading edge of a document is inserted by a roller arrangement. When the document is released by the roller arrangement it registers against the bottom wall of the pocket and a fluid stream provided in the pocket registers the document against a narrow vertical wall of the pocket. The wide walls of the structure are transparent and provide a view of the document which may be used in cooperation with xerographic equipment to produce copies of the document. Another fluid stream in the pocket is used to move the originally trailing edge of the document into engagement with the roller arrangement and the arrangement cooperates with a guide to move the document into a tray. The facing position of a collected document is inverted with respect to its facing position immediately prior to its being fed into the roller arrangement.
