Abstract
When a book copy mode is selected, a scanning system is set to a size corresponding to divided original areas. If an automatic paper selection function is being set, a size of paper used for copy is determined based on an input copying magnification and the thus set size for the scanning ssystem. Existence of paper of the determined size in a paper feed cassette is examined and if the paper exists, copy operation is performed. If it does not exist, a display of the paper size is caused to blink. In the book copying mode, the area size of one page of the book is manually designated by the operator, and this area designation parameter is used to set the projection magnification of the optical scanning system. On the other hand, if an automatic magnification selection function is being set, the copying magnification is determined based on an input paper size and the thus set size for the scanning system. Then, copy operation is performed by using the determined copying magnification.
