Abstract
In an electrophotographic copying machine of the type in which an original copying platen is mounted at one side of the body of the copying machine with a corner of the platen at the exterior side of the platen adapted for book copying, and in which the scanning starting point of a document exposure lamp which scans the entire platen is from the side of the platen opposite from the corner of the platen, there is disclosed a platen repositionable by movement toward the scanning direction of the exposure lamp to shorten the exposed or scanned area of the platen and to move the edge of a book page on the platen to the copier registration position for copying of the book page onto a smaller copy sheet corresponding in size to the book page rather than the platen size.
