Abstract
The present invention is directed toward a flexible plastic platen used as a document support surface in a copying/printing machine. The platen, in a preferred embodiment, is an optically clear polycarbonate sheet, inexpensive and easy to handle. The platen is mounted in a machine frame so as to be slightly flexed upward along a width area corresponding to the area to be scan-illuminated to ensure accurate focusing of the document image through an underlying linear lens array. The platen is easily replaced by releasing the tension and lifting the platen out of a seated position.
