ABSTRACT:
An imaging apparatus comprising a counterfeiting prevention arrangement and reliably preventing counterfeit reproduction of currency, negotiable certificates, and other registered documents is provided by preventing modification or removal of the counterfeiting prevention arrangement. Modification or removal of the counterfeiting prevention arrangement is prevented in this imaging apparatus by integrating circuit elements or components of the counterfeiting prevention arrangement with circuit elements or components of the image processors of the imaging system in a single chip, or sealing these components in a single mold, effectively preventing modification or removal of the counterfeiting prevention arrangement without disabling the imaging system.
