Abstract
A duplex scanning apparatus capable of switching a scanning background includes a pair of glass plates, a pair of background boards pivoted to the glass plates and a driving mechanism. The glass plates are disposed in a frame and overlapped with each other. The two glass plates define two scanning areas face to face. A portion of the frame adjacent to an outer surface of the glass plate defines a first color area of the scanning background corresponding to the scanning area. One background board is positioned above one glass plate, and the other background board is positioned under the other glass plate and away from the one background board. Each background board defines a second color area of the scanning background corresponding to the scanning area. The driving mechanism mounted in the frame drives the background boards to turn over with respect to the corresponding glass plates.
