Abstract
A method and apparatus is disclosed for receiving and processing a stack of small documents, such as checks. The documents are stacked in front surface-to-back surface relationship and are singly fed from the stack automatically into a path. The advancement of every two documents is interrupted for a period of time at predetermined positions along the path to effect a selected spacing between the two documents and to align their leading edges. Subsequently, the interruption of the movement of the two documents is terminated to allow the documents to continue forward in a pair at the selected spaced apart distance. The apparatus for effecting this method comprises a document feeder apparatus, a conveyor apparatus defining the document path, and a pair of rotatable gate members which rotate into and out of the path for interrupting the advancement of the documents.
