Abstract
An electrophotographic copying machine includes a document mount portion, a document-winding drum, and a selection element. A book-like document can be copied when it is mounted on the document mount portion or a sheet-like copy document can be copied by being wound around the document drum by operation of the selection element. The document mount portion and the document drum are positioned within the range of movement of a common light scanning source so that the copy document provided on either the mount portion or the drum is optically scanned with the common light scanning source.
