Patent ID: 8199374

Claim:
A document cover for retaining a document sheet against a scanning surface of an image capture system, the document cover comprising: a body that is oriented substantially parallel to the scanning surface when the document cover is in the closed position; a compliant and elastic document backing that is partially attached to the body and configured to reflect light originating from the image capture system; and a backing constraint configured to secure a central region of the document backing directly to the body without intermediate layers between the body and the document backing, in which the central region extends across a width of the document backing from a first edge of the document backing to a second edge of the document backing and is further configured to constrain movement of the central region in a first direction that is normal to the body in the closed position while allowing movement, in the first direction, of outer regions that are lateral to the central region, the document backing generating a downward spring force which biases the outer regions toward the scanning surface when the document cover is in the closed position.
