Abstract
The present invention relates to a special-document discriminating apparatus used for providing a counterfeit preventing function to a digital copy machine and the like, and to a managing system for an image forming apparatus having a special-document discriminating function. The special-document discriminating apparatus is provided with a ROM for discriminating a special-document such as paper money, which ROM is detachably attached to a controlling circuit board. Data used for determination may be learned from test pattern data input from the image forming apparatus, or the data may be input from an external unit via a communication line. The managing system for an image forming apparatus comprises an image forming apparatus and a managing apparatus connected to the image forming apparatus. Either the image forming apparatus or the managing apparatus has a special-document discriminating function. Additional information is sent from the image forming apparatus together with determination result information or detected data. Information used as reference for determination may be sent from the managing apparatus to the image forming apparatus.
