ABSTRACT:
When a plurality of document sheets are sequentially transported by a belt to a document scanning area facing an optical scanning means, a clearance is formed between the belt and the document scanning area on the upstream side with respect to the document transporting direction. When a document is positioned in the document scanning area, a succeeding document is preliminarily transported until the leading edge thereof enters the clearance and contacts the belt. As a result, when the belt is driven to discharge the scanned document from the document scanning area, the succeeding document is quickly transported to the document scanning area. The time required for document transportation can thus be reduced.
