Abstract
A document scanning system having a platen for scanning bulky documents and two separate exposing stations for front and reverse side scanning of automatically fed sheet-type original documents. The platen and the two exposing stations are arranged in a common plane for scanning by scanning elements carried on a linearly driven carriage. Image sensing is performed by CCD arrays mounted on the scanner carriage. Scanning at the two exposing stations is conducted with the scanner carriage stationary, while platen scanning proceeds with the scanner carriage moving linearly at a uniform speed.
