Abstract
An image forming apparatus with an automatic document feeding apparatus which is mounted on a platen glass or document table of an electronic copying apparatus having an interruption copy mode function. A document transportation belt of the automatic document feeding apparatus is stretched facing the platen glass. When an interruption key is depressed, the document transportation belt and transportation rollers of a document discharge device are driven so that an uncopied document on the platen glass is moved to be temporarily evacuated from an exposure region. The evacuated document is held between the transportation rollers and pinch rollers. In this state, the automatic document feeding apparatus is opened, and an interruption document is manually set on the platen glass. Subsequently, after closing the document feeding apparatus, interruption copying operation is performed. After the interruption copying operation is finished, the interruption document is removed, and the document feeding apparatus is closed. Then, the interruption copy mode is canceled by depressing the interruption key again. When the interruption copy mode is canceled, the transportation rollers and the document transportation belt rotate reversely, thereby automatically restoring the temporarily evacuated document to an exposure position on the platen glass.
