A document transport for a document scanning device has an elevator for locating a stack of documents to be fed automatically into position to be scanned. The top document is removed from the stack by a feed roller. Other documents which may become entrained with the top document are returned to the stack by separation rollers. The top document is driven into the scanning device against an alignment gate and this action eliminates any skew in the position of the document. At a read or scan station beyond the gate, which is reached by the document once the alignment gate has been withdrawn, the data on the document is scanned as the document is moved by read rollers in a controlled fashion. As the document leaves the read station it is trapped between the two single opposing belts in a buffer unit, which move the document at the spped of the scanning rollers. When the end of the document leaves the read station the buffer unit changes speed and the document is accelerated to a higher eject speed by the opposing belts.
