To accomodate copying of pages from a book, the copying platen 10 is frequently positioned along one edge of the top of a reproducing machine. A book may then be placed on the platen so that one page can be copied while the page on the opposite side of the book rests over the platen edge. When copying single sheet documents, it is also conventional to use a platen cover 12 to hold the sheet in position during copying. However, after copying, when the platen cover is lifted, a slight air flow is created with air rushing in between the sheet and the platen while the sheet remains temporarily, partially tacked to the platen cover. As the cover is further moved off the platen, the sheet tends to follow the air flow and slides off the platen and onto the floor. To minimize this occurence, a fixed, hooked lip 14 is added near the edge of the platen 10 to intercept a sheet from falling onto the floor. Typically, the platen cover has a cutout portion or gap 16 through which the hooked lip passes during opening and closing of the cover.
