Abstract

An automatic document conveying apparatus in which a normal continuous document conveying state and a single document conveying state, suitable for a document having high importance such as an original of a design, can be selectively determined, and carrying and discharging of documents can be fully well conducted. In a document carrying passage, a restricting member and a separation roller which cooperate with a feed roller are disposed. The forward end of the restricting member approaches or contacts the feed roller, and the separation roller is driven to rotate in a direction opposite to the document conveying direction in the continuous document conveying state. In the single document conveying state, the restricting member is isolated from the feed roller, and the separation roller can be freely rotated.
