ABSTRACT:
An imaging system which uses a right-to-left scanning operation is enabled by first detecting by an optical sensor the right hand edge of a document to be copied, the left edge of the document being registered at the left edge of the platen. The scanning operation is initiated at the detected right hand edge and proceeds to the left. The end of scan coincides with the left registration edge. Book copying is enabled by adding a sloping left edge to the platen placing the book to be copied over the edge corner. The optical system is rotated for a book copy mode so that light penetrating the binding area is transmitted along the optical path. This arrangement allows required pre-scan excursion to take place in the space to the right of the start of scan position, thus avoiding interference with the sloping book edge.
