Abstract

The present invention is a cover designed for use with flatbed image scanners to eliminate external light pollution on images when the object scanned is too large or thick to properly close the document cover attached.

This text was extracted from a Microsoft Word document.
At least one non-text object (such as an image or picture) has been suppressed.
This is the abbreviated version, containing approximately 76% of the total text.
