Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
197 words
A special-document discriminating apparatus, connected to an image forming apparatus, which determines whether or not image data input from the image forming apparatus corresponds to a predetermined special-document, the special-document discriminating apparatus comprising: storing means, detachably attached to a controlling circuit board such that the storing means can be independently detached from the controlling circuit board, for storing discriminating information used for determining whether or not the input image data corresponds to a special-document; determining means for determining whether or not the input image data corresponds to the special-document in accordance with the discriminating information supplied by said storing means, and outputting the result of the determination to an external unit; judging means for judging whether or not said storing means is attached to said controlling circuit board; and operation prohibiting means for outputting a signal used for prohibiting the operation of said image forming apparatus when said judging means judges that said storing means is not attached to the controlling circuit board, wherein said storing means is separated from said determining means provided on the controlling circuit board, and is replaced with another one so that only the discriminating information is changed to new discriminating information.
Claim 2
Dependent Claim
197 words
A special-document discriminating apparatus, connected to an image forming apparatus, which determines whether or not image data input from the image forming apparatus corresponds to a predetermined special-document, the special-document discriminating apparatus comprising: storing means, detachably attached to a controlling circuit board such that the storing means can be independently detached from the controlling circuit board, for storing discriminating information used for determining whether or not the input image data corresponds to a special-document; determining means for determining whether or not the input image data corresponds to the special-document in accordance with the discriminating information supplied by said storing means, and outputting the result of the determination to an external unit; judging means for judging whether or not said storing means is attached to said controlling circuit board; and operation prohibiting means for outputting a signal used for prohibiting the operation of said image forming apparatus when said judging means judges that said storing means is not attached to the controlling circuit board, wherein said storing means is separated from said determining means provided on the controlling circuit board, and is replaced with another one so that only the discriminating information is changed to new discriminating information.
Claim 3
Dependent Claim
36 words
The special-document discriminating apparatus as claimed in claim 1, further comprising: communication controlling means for receiving the discrimination information from an external unit via a communication line, and outputting the discriminating information to said storing means.
Claim 4
Dependent Claim
43 words
The special-document discriminating apparatus as claimed in claim 1, wherein said storing means is a ROM package attached to said controlling circuit board via a socket, and said judging means judges whether or not said ROM package is effectively attached to said socket.
Claim 5
Dependent Claim
48 words
The special-document discriminating apparatus as claimed in claim 1, further comprising new paper learning means for extracting the discrimination information of the special-document, when a predetermined signal is input, from the image data input from the image forming apparatus, and inputting the discrimination information to said storing means.
Claim 6
Dependent Claim
61 words
The special-document discriminating apparatus as claimed in claim 4, wherein an original used for generating image data, when said predetermined signal is input, is a test pattern having only features necessary for discriminating the special-document, and said new paper money learning means comprises test pattern learning means for extracting the discrimination information from the image data according to said test pattern.
