Abstract
An image formation apparatus is operable in two different modes. The selection of a mode is made automatically, depending on the size of the document to be scanned. If the document is bulky like a book and is placed on a document table by opening an automatic document feeder or if it is or sheet-like but long and cannot be wrapped around a document winding cylinder, the optical system is moved to scan the document. If the document is sheet-like and sufficiently short, it is wrapped around the cylinder and is scanned by a stationary optical system while the cylinder is rotated.
