A platen cover for a multi-mode copier includes a document turnaround and stacker device and a platen cover pad. The copier comprises a viewing platen for viewing a stationary document and a document feeder, which when placed over an edge of the platen feeds a document past a scanning slit for scanning a moving document.

Referring to Figure 1, a document turnaround and stacker device is integral with the top of the platen cover and comprises feed rolls 12 to transfer documents from platen 10 to document tray 13. The platen cover also contains a platen pad 14 which as a thin, opaque, white surface layer 19, such as Mylar, in contact with the platen. The platen pad has a foam backing to uniformly hold documents close to the platen surface. This pad covers the entire platen surface except that the foam backing is removed for the small portions of the feed rolls 12 that contact the platen. The platen cover is pivotally mounted on hinges at the rear for use in conventional, single-document copying mode. Thus, the cover may be raised for insertion and withdrawal of a document. Alternatively, the document feeder may be moved from the stored position in Figure 1 to the operative position in Figure 2 wherein document feed rolls 16 and 17 transport the document passed viewing slit
