Abstract
During the time period since a document placed at a multi-document tray is transported by a roller pair and has its images on the front surface read until the roller pair is reversed to start reading the back surface of the document, a document placed at a single feed tray is transported by another roller pair for interrupt reading of the document. The interrupt reading can be achieved without interrupting the transportation of the current document and replacing the document.
