Zusammenfassung:This invention provides a high reliable paper-category recognition equipment, which can accurately ascertain the number or category of the papers even if the papers with bad transportation state such as overlap transportation or skew transportation and with various states caused by the bending, breach, damage of the papers themselves are transported. This invention is characterized in that a thickness-sensor is mounted along the transportation width direction of the recognition-transportation path for transporting the papers, several thickness-detection elements are arranged across the whole width of the transportation path. The profile data of the paper-category is extracted from the thickness data detected each time from the thickness-detection elements of the thickness-sensor. The extracted profile data are compared with the profile-base data, which is used as the base stored in the memory device, of the papers and then the number of the paper-category can be determined.
