A document conveying apparatus has a document pushing-down/adjusting mechanism disposed at an upper position on the downstream side of a document discharge port. The document pushing-down/adjusting mechanism acts on the rear end of the document on delivery after its rear end is substantially liberated from being nipped by a pair of document discharge rollers, forcibly pushes the rear end of the document down toward the upstream end position on the document-placing plate means, and holds the document for the document-placing plate means for a predetermined period of time.
