Abstract: A document feeding apparatus sequentially feeding documents, including an automatic feeder for removing one document at a time from a stack and for delivering each document to a feed path. An endless conveyor moves each document along the path towards a document aligning gate means that temporarily interrupts the movement of the documents to effect desired alignment thereof. The automatic feeder and the document aligning gate are automatically controlled so that the documents are selectively removed from the stack as a function of the preceding document moving along the path. A pair of printing heads are positioned along the path and are respectively actuated in response to movement of the documents so that the documents can be printed at accurately positioned locations on a surface thereof.
