ABSTRACT:
A device for pressing down a document to be duplicated on a document table of an electrophotographic apparatus comprises a flexible cover which is journaled along its one edge portion and a supporting frame which supports the document cover in an opened or upright position. Near the free end of the document cover there is secured a handle or grip which engages with the supporting frame. In case of duplicating a thick document such as a book the handle can be disengaged from the frame and the thick document can be effectively pressed down on the table by means of the document cover. The document cover and the frame are detachably arranged at positions which are lower than the surface level of the document table. Documents larger than the document table can be easily duplicated by removing the document cover and the supporting frame.
