Abstract
A wedge shaped platen scanner sequentially records opposing pages of a bound document positioned thereon using a single imaging station. A mirror is positioned between the wedges of the platen. A controller positions the mirror in one of two operational positions. In the first operational position, the mirror is positioned so that light emitted by a lamp reflects off of the mirror and onto the single imaging station. In the second operational position, the mirror is moved out of the imaging station's optical path. In each operational position, the lamp sequentially illuminates an opposing page of the bound document with each of the three primary colors: red green, and blue. In both the first and the second operational positions, images of opposing pages of the bound document are focused with optics onto the imaging station. In one arrangement, the imaging station is a two-dimensional array of detectors which sense an image of a page of the bound document projected thereon. In another arrangement, the imaging station is a photoconductive belt which when exposed by either flash lamp records a latent image thereon. In either arrangement, a one page imaging station records opposing pages of a bound document either electronically or on print media, one page at a time.
