Abstract
Abstract THE INVENTION RELATES TO A SLOT-TYPE DOCUMENT VALIDATION APPARATUS. THE INVENTION IS CHARACTERIZED BY HAVING THE DOCUMENT MANUALLY POSITIONED INTO A TESTING AREA WITHOUT THE USE OF ANY TRAYS, BELTS, OR THE LIKE. VALIDATION IS ACCOMPLISHED BY KNOWN TECHNIQUES, AND THE DOCUMENT IS THEN REMOVED FROM THE TESTING AREA UPON PROPER VALIDATION WITH A POSITIVE REMOVAL SYSTEM THAT ELIMINATES THE POSSIBILITY OF THE DOCUMENT BEING REMOVED FROM THE TESTING AREA BY ANY WAY OTHER THAN THE POSITIVE REMOVAL SYSTEM, SO THAT IF THE DOCUMENT IS MANUALLY OR OTHERWISE RESTRAINED, THE REMOVAL SYSTEM WILL AUTOMATICALLY REJECT THE DOCUMENT AND CANCEL THE VALIDATION.
