ABSTRACT:
When copying is automatically started using an automatic original document feeder, an automatic start operation is prohibited after an original document jam is eliminated. When copying operations are interrupted due to an original document jam during the copying operation, an automatic original document feeder is opened and a jammed original document is removed, and the automatic original document feeder is closed again and the original document jam is eliminated, in the case that there still is an original document remaining in the automatic original document feeder after the original document jam is eliminated. An automatic start prohibiting flag is turned on. Conversely, when there is no original document remaining in such a manner, the automatic start prohibiting flag is turned off. Thus, even when there is an original document remaining in the automatic original document feeder after the original document jam is eliminated, the automatic start operation upon detection of an original document is prohibited so that a time for setting the jammed original document which is removed once again is ensured.
