Abstract
Abstract Scanning and selection methods and apparatus as well as an electrophotographic printing system employing such scanning and selection apparatus are provided in accordance with the teachings of the present invention. In an exemplary embodiment of the invention a plurality of coded data records containing selection information and a plurality of coded data records to be classified for selection purposes are scanned by code sensing devices. Code information from each of the plurality of coded data records containing selection information is loaded in sequence into memory apparatus to store therein the selection conditions to be imposed upon the plurality of coded data records to be classified for selection purposes. The selection information obtained being directed to a plurality of selection considerations and such sequence being arranged in a manner so that each of the plurality of selection considerations is defined in different areas of the memory apparatus. Subsequently code information from each of the plurality of coded data records to be classified is loaded in comparing apparatus for comparison with the selection conditions to be imposed as stored in the memory apparatus, the comparing apparatus acting to impose each of the plurality of selection considerations upon code information from each of the plurality of coded data records to be classified and provide a classification signal for each of the plurality of coded data records to be classified for selection purposes based upon all of the selection considerations imposed.
