Description

  The present invention relates to a monetary science appraisal system that determines the authenticity of money using state information and component information on the surface of money.

  In recent years, in the money collection industry, there are many sophisticated counterfeit coins mainly targeting collection money that is bought and sold with a premium, and it is difficult to judge authenticity or it is due to uncertainty or uncertainty. However, there is a tendency to increase distrust and credibility of money collection, and the sound distribution (buying and selling) of collected money (especially old coins) and its property are being severely impaired.

Traditionally, the appraisal of money has been done by using a magnifier such as a magnifying glass or a microscope to confirm the pattern or pattern on the money surface that has been stamped or printed, or to make a promise on the money surface (the promise on the stamp). ) And confirmation of basic promises in monetary manufacture, etc. based on the information on the stamps in the target money, and in some cases, with a democratic agreement such as a consensus or majority vote of multiple appraisers, Judgment was made as to whether or not it could be regarded as coincident, and true or false was judged. FIG. 2 (steps S21 to S24) shows a flow of appraisal work in a conventional general money appraisal system. As an apparatus using such a conventional system, there is a coin discriminating apparatus of a collective throwing coin processor as disclosed in Patent Document 1.
In addition, there are cases in which the metal component of money is measured on a trial basis, but the basic metal component and its content ratio (the ratio of gold to other metals in the case of gold coins, the silver content and other in the case of silver coins) It is mainly used to check the ratio of metals), and the measurement / evaluation cost is high, so it may be used from a research point of view, but it is not generally used.

  In addition, in order to keep the authority of appraisal high, appraisal and grade evaluation of money are conducted to some extent mechanically, professionally and organizationally, and the target money is sealed in a special case along with the appraisal results. Examples of services include PCGS (Professional Coin Grading Service), a US coin grade rating company. In order to keep the appraisal trust and authority higher than general monetary appraisal systems, appraisal work in expert appraisal systems that are expertly organized with a degree of mechanized appraisal (including computerization) and grade evaluation function FIG. 3 shows an example relating to the flow (an appraisal procedure mainly for engraving metal money).

  In recent years, with the advancement of science and technology, copy-type counterfeiting technology has been developed that can almost completely copy genuine stamps from true coins, etc. It has become difficult to judge. Also, the premium (rare value) of the money for collection is much more expensive than the value of the main metal components that make up money such as gold and silver, and the content and ratio of the main metal components are confirmed. Doing so is no longer the decisive factor for authenticity.

JP 2003-256902 A

  The present invention enhances the rigorousness of monetary appraisals and more reliably identifies counterfeit money, falsified money and bad money in the collection money field and market, in particular in the old money field (old money collection industry, old money trading). In order to protect the asset value of money and to promote sound distribution (buying and selling) of money for collection, it is an issue to conduct more scientific and professional money appraisals.

In order to achieve the above-mentioned objects and problems, elemental component information of the vicinity of the surface of the appraisal money (for example, mainly from the surface of the money to a depth of about 0.5 mm) measured under non-contact and non-destructive conditions And scientific information including state information (especially the metal state near the surface of money, shine and old color (tone)), and database information and monetary components related to money stamps prepared for the entire group of money to be judged On the basis of various objective database information such as database information, etc., regarding the various components that constitute the appraisal currency as well as obtaining intellectual judgment information for authenticity judgment from the statistical processing and numerical analysis processing of the appraisal currency A system for deriving a conclusion for authenticity or pass / fail judgment must be established by performing validation from various aspects.
Therefore, in a system for non-destructively determining the authenticity or quality of money, component measurement information acquisition means for acquiring component measurement information by measuring information of components constituting or forming the money to be verified, and the money to be verified The state information acquisition means for acquiring the state information, and the component constituting the money or the combination evaluation value of the ingredients are the range of the component constituting condition determined for the genuine product of the money or the estimated component constituting condition obtained statistically Component composition condition judging means for judging whether or not to fall within the range of the component, the component measurement information and the state of the money, the composition value of the component to be noted among the components constituting or forming the money detected from the money to be judged Specific component configuration estimation means for combining and estimating information, and a measured value of the noteworthy component in the components constituting or forming the appraisal target money is the specific component configuration estimation It means for determining whether to enter the range of the estimated values obtained by means by providing, to provide a monetary science expert system of interest.

  The monetary science appraisal system provided by the present invention can present objective and intelligent judgment information as to whether or not a target money is appropriate as a genuine product from the viewpoint of its constituent components. By using this new judgment information in combination with validation information such as promised items and surface conditions in the engraving of money using a magnifying glass, etc., a more precise and scientific professional appraisal can be achieved. This makes it possible to provide an appraisal service with higher reliability than before.

FIG. 1 shows an embodiment of an appraisal system for metal money regarding the flow of the professional and scientific money appraisal system and the appraisal procedure provided by the present invention. Hereinafter, the flow of the money appraisal procedure in the present invention shown in FIG. 1 will be described in detail.
The monetary science appraisal system according to the present invention uses a computer system to display the appraisal procedure on the display screen from the receipt of appraisal request money reception described below to the issuance of the monetary component appraisal. The system, the analysis system, and various databases necessary for the appraisal are used, and the description regarding the specific hardware configuration and the specific operation at the terminal is omitted.

[1] Appraisal request money (coin) reception (step S1)
Accept appraisal of the target currency. Here, it is confirmed whether or not it matches the information on the target currency and the appraisal acceptance conditions set by the money appraiser, and after receiving necessary information, the acceptance processing is performed. For example, the appraisal client deposits the target money with the money appraiser, and the money appraiser acquires and confirms the necessary information, that is, describes the basic matters related to the target money, requests regarding the appraisal client's appraisal content, and is subject to the appraisal. Confirmation of whether or not it corresponds to the current currency, confirmation and recording of the basic status of the appraisal product, confirmation of past appraisal history information, information on the location and time of acquisition, confirmation of the storage environment, setting of the appraisal number, etc. Then, the target money is put into the appraisal system of the present invention.

[2] Prior preliminary appraisal (preliminary sorting and defect removal by engraving preliminary appraisal) (step S2)
A preliminary appraisal is performed in advance by a money appraiser, and it is determined whether it is worth performing the main appraisal (the processing after [3]), and necessary processing is performed based on the conditions set by the appraiser. For example, if it is judged that the product is an obvious defective product or counterfeit and has no research value, it will be communicated to the appraisal client and returned or the appraisal will be continued and the appraisal will be issued. Confirm with the client. If it is judged that defective products or counterfeit coins are worth research, it will be confirmed to the appraiser and whether or not an appraisal will be issued. From the viewpoint of enhancing the database of research and appraisal systems, the appraisal will be continued at the appraiser's expense with the consent of the appraiser. In some cases, only the processing after “measurement of elemental components near the surface of money” shown in [4] and [5] is performed. If it is determined that there is no problem in the prior appraisal (deserves appraisal), the present appraisal is transferred unconditionally to [3] and later.

[3] Professional stamping appraisal (detailed appraisal regarding money stamping) (step S3)
In this process, a full-fledged imprint appraisal is performed. The imprinting of money basically means whether the imprinting of the pattern imprinted on the money subject to the appraisal or the indentation of the edge of the money can be regarded as genuine. Structure (engraved stamp structure, surface roughness, sharpness, etc.) and conventions (proposals such as money stamp classification features and combinations), magnifier, computer image data, etc. This is to make a thorough inspection and judgment by pattern matching processing (comparing with genuine data). Physical conventions such as quantity (weight) and external dimensions are also inspected. A precise photograph of the target currency is also taken in this step and used for identification of the currency to be verified (used as an ID photo for proving that it is a target currency) or converted into digital data for use in matching processing. Further, in the last step 3-4, the surface condition information of the target money is measured and used as information used in the money component appraisal (processing steps [4] and [5]) and information for evaluating the money grade. Means for inspecting (state information acquisition means) is provided. The state information of the money surface is mainly the surface roughness state of the target money, the state of color and tone, the state of brightness and reflection, the state of scratches and dust, the state of artificial polishing and treatment, etc. In the monetary component identification, it is important as index information for classifying or searching the monetary component database. As a means for measuring / inspecting the surface state information, a photometer, a radiation meter, a spectroscope, a magnifying glass, or the like is used. In order to carry out the stamp appraisal more strictly, it is desirable that a specialized money stamp appraiser performs the appraisal.

The general flow is as shown in 3-1 to 3-4 described in [3] Professional stamping appraisal in FIG. 1, but the procedure does not necessarily have to be performed in the order of this example. When a professional engraving expert) performs an appraisal operation, a matching process by a computer may not be required.
In addition, when it was certified as NG (defective) in Steps 3-1, 3-3, it was judged as [3] defective or counterfeit on the professional engraving and was recognized as OK (good). In this case, it is judged as a genuine product. If it is judged as genuine, the grade is also presented in principle. In the case of defective products, grades may be presented in some cases.
In this example, the appraisal of metal money is taken as an example, but for paper money such as banknotes, the same appraisal process can be used if information on printing and promises are used instead of information on stamps and promises. Is possible.

[4] Element component measurement near the surface of money (component measurement information acquisition means) (step S4)
[3] If it is deemed necessary by the professional engraving, if the requester strongly desires, or if there is a research requirement, etc., in order to keep the accuracy, credibility, authority, etc. of the appraisal higher, In order to accumulate statistical data and scientific data related to constituent element components, [4] elemental component measurement near the surface of money is performed, and detailed component information constituting or forming money is acquired. This process is called component measurement information acquisition means.
In this process, using a measuring device such as an X-ray device or an accelerator device, all of the area around the surface of the target money is collected under non-destructive and non-contact conditions (does not damage the money even if contacted). The constituent element components are measured. Although it varies depending on the measurement device to be used, it is desirable to use a high-performance measurement device that has an effective measurement depth of about 0.5 mm or more from the surface. If a large-scale measuring device using an accelerator is used, some metal coins having a thickness of several millimeters can be measured by penetrating in the depth direction. Measurement result data file such as component composition ratios corresponding to each monetary quantity that is measured by mechanically and automatically continuously measuring a large number of pieces (for example, periodically measuring about 50 pieces as one lot). The measurement cost can be greatly reduced by assigning the measurement process at once, for example, by automatically creating a computer with a computer, or at night or when the measurement device is available. Analysis and judgment are not performed in this process, except for the confirmation and fine correction of elements that may be misrecognized in the list of component elements automatically collected by the machine. [3] Comprehensive and collective processing by combining the surface state information of the target currency obtained in step 3-4 of the professional engraving appraisal and the constituent element component information of the target currency obtained in this step. By implementing this, it is possible to prevent multiple analysis costs from occurring and to reduce the appraisal cost. In addition, if a measurement chart file for all elements (raw measurement data such as all element spectrum) is automatically generated for each measurement currency, [5] As information on more minute elemental components in professional component identification Can be used.

Here, it is proposed to measure all elements, but depending on the measuring device, there are strengths and weaknesses in measurement depending on conditions such as the mass of the element, so if the range of the main element is determined, the measurement target It is also possible to determine the range of elements and to select a measurement apparatus suitable for the element range and perform component measurement.
Although an example of measuring elemental components has been explained, the measurement component unit may be measured by treating a molecular component composed of a plurality of elements as one component unit, or a plurality of elements may be measured one by one. It may be measured as a combination component.

[5] Expert component appraisal (detailed appraisal regarding the components of money, presentation of analysis and intelligent judgment information based on component measurement information and surface condition information) (step S5)
In this process, [4] the elemental component constituting the vicinity of the surface of the target money measured by measuring the elemental component near the surface of the money is the state near the surface of the various money (surface condition and grade evaluation), the money It changes considerably depending on the year of issue (changes in elemental components due to year, changes in elapsed time and storage conditions, etc.) In order to capture this change information and link it to monetary appraisal by component, many monetary component databases classified with respect to similar (approximate) monetary component information of a large amount of genuine and counterfeit products that have been statistically processed in advance are established and appraised. A database to be applied to the target currency is determined and used for analysis processing and comparison processing, and quality determination regarding components is performed.

  For the determination of the database to be applied to the appraisal currency, the above-mentioned state information near the surface, year era information, etc. are used as index information. That is, the measurement / inspection results in “3-4: Measurement of surface state information and grade evaluation of engraving” in [3] Professional engraving appraisal are important. Especially, the surface condition information includes change information such as component changes due to chemical changes near the surface of money over the years, component changes due to elements attached to the surface, various changes due to money making and surface roughness, etc. It is very important in classifying databases. Grade evaluation is also useful for estimating the storage status and classifying the database according to the information.

  As an initial comparison / determination process to determine the quality of components, basic evaluation information such as basic component information or combination ratios and differences in this component appraisal is the genuine evaluation value range (element component). It is checked whether it is within the range of the composition condition or the range of the estimated component composition condition obtained statistically). The basic component information that should or should not be included is also examined here. When there is a problem, an expert judgment person (appraiser concerning the component) makes a good / bad judgment on the highly accurate monetary component in consideration of more complicated combination conditions by an interactive judgment system. This comparison determination process relating to the basic component configuration is called component configuration condition determination means. Note that this interactive system method is the same in the pass / fail judgment processing relating to components by analysis processing and comparison processing using a database of monetary components to be applied to appraisal target currency, which will be described later, and an evaluation function corresponding thereto.

  Furthermore, by combining the constituent values of notable components in the element components detected from the appraisal target currency with other component measurement information constituting the money and the state information of the money, more complicated statistical processing and numerical values A specific component configuration estimation unit is provided that estimates by an evaluation function obtained using an analysis process, and a measured value of an element component to be noted among the element components that constitute or form the appraisal money is determined by the specific component configuration estimation unit. Information is presented to determine whether it falls within the range of estimated values obtained. The result is different from genuine products whose surface condition has changed due to chemical changes after a considerable number of years since manufacture, such as old coins, and counterfeit products or defective products that have been manufactured in the later years or have been modified. There are many cases. That is, in many cases, information on whether or not it is a counterfeit coin with a new surface state that has been manufactured in recent years, whether it is a special element component or element component configuration that is artificially modified and different from the genuine product, etc. Can be extracted as an error from the allowable range of the genuine product, and the quality can be comprehensively confirmed and judged. It should be noted that such evaluation functions for determination are provided in units of classified component databases, parameters of evaluation functions are changed according to conditions such as surface state information, and different types of evaluation functions are prepared. By selecting a plurality of elemental components and providing an evaluation function for each of them, a plurality of evaluation functions such as an evaluation function can be prevented, and the accuracy of appraisal information can be improved.

  Judgment whether the notable element component in the appraisal money falls within the range of the estimated value obtained by the specific component composition estimation means is also used in combination with the combination condition with the comparison processing result by the component composition condition judgment means described above. In many cases, it is determined comprehensively. In order to support this work, as in the case of basic comparison / determination processing by the component composition condition determination means, if there is a problem, an expert decision judge (appraiser regarding ingredients) becomes more complicated by an interactive decision system. In consideration of various combination conditions, a pass / fail judgment regarding a highly accurate monetary component is performed. Then, as comprehensive information for final component appraisal of the target currency, intelligent judgment information regarding authenticity determination or pass / fail determination is presented.

  Although the component units to be measured are explained here as elemental components, molecular components composed of multiple elements may be treated as one component unit and used for analysis and evaluation, or multiple elements may be combined in one You may treat as a component and use for analysis and evaluation. These condition settings for component units also depend on the properties of the component measuring device, and the properties and construction methods of the component database and evaluation function will change accordingly. There is no change in this part.

The rough flow of the processing is as shown in [5] Expert component identification 5-1 to 5-3 in FIG. 1 and is an important requirement of the present invention, and will be described in more detail below.
(1) 5-1: Comparison processing between the genuine component database based on the surface state classification and the component measurement information of the target money (compare each component or its combination information with the database) This is equivalent to `` inspecting whether basic information such as component information or a combination ratio or difference thereof is within the range of genuine products '', and is a process of obtaining basic comparison / determination information by providing component constituent condition determination means is there. If the target currency contains more than a certain range of components that can be clearly regarded as defective in this process, or if a clearly different component composition ratio can be confirmed, the target currency is determined to be defective at that time. However, if there is a problem that cannot be judged simply, an expert judgment person (appraiser on the ingredient) will take into account more complicated combination conditions by using an interactive judgment system. Make a decision. The comparison process uses a computer to select a basic component database that the target money is considered to belong to (select an appropriate component database classified from the surface state information as described above) and compare it with it. Information for pass / fail judgment is generated. The information obtained here is also used in steps 5-2 and 5-3.

  (2) 5-2: Comparison processing between the analysis database of genuine products based on the surface state classification and the component analysis information of the target currency (comparing the component analysis information with the database) The constituent value of the element element to be noted among the elemental elements to be formed is obtained by combining more information on the measurement of the other constituents of the money and the state information of the money, using more complicated statistical processing and numerical analysis processing. It is equivalent to “estimated by an evaluation function”, and a specific component component estimation means is provided to detect an element component that is detected from the appraisal money (that can be regarded as one of the components constituting or forming money). Provides information to determine whether the measured value of the power element component (especially the component detected from the vicinity of the money surface) falls within the range of the estimated value obtained by the above-mentioned specific component configuration estimation means It is a process. In principle, an evaluation function is provided corresponding to a database of classified money components and the like, and can be regarded as a function that comprehensively represents the characteristics and characteristics of the database. When numerical analysis is performed by substituting the component measurement data of the appraisal currency into the evaluation function, an estimated value of the element component of interest in the target currency is immediately calculated, and the allowable range in the selected database (e.g. The range of the estimated value considering the range) can be determined. Then, information for determining whether or not there is an abnormality in the component of the target currency can be obtained by comparing the allowable range of the estimated value with the actual measured value of the element of interest element. If a plurality of databases are prepared, a plurality of evaluation functions can be prepared, and a lot of information for comprehensive and diversified quality determination regarding money components can be acquired. In this way, a mechanical method is used to determine whether or not the measured value of the component to be noted among the components constituting or forming the money to be verified falls within the range of the estimated value obtained by the specific component configuration estimation means. It is possible to easily present judgment information in component appraisal to the appraiser, or to organize a large amount of information efficiently and to present advanced intelligent judgment information in 5-3. Become. Basically, the final decision on which evaluation function is to be used or prioritized, and which evaluation function results are used in combination is based on the year of the production period, Based on the basic information of the currency subject to appraisal, such as grade evaluation and storage status, and the surface condition information of the appraisal currency obtained in [3] Special Engraving Appraisal 3-4, examine again in 5-3. Implement intelligently and comprehensively.

  (3) 5-3: Intellectual judgment information presentation regarding authenticity determination or pass / fail judgment (based on comparison information with component measurement information, comparison information with component analysis information, and stamped appraisal information, etc., from various aspects) Validity verification is performed and intelligent judgment information for authenticity determination or pass / fail determination is presented), with a large amount of information for pass / fail determination obtained by 5-2 and 5-3 as the subject, [3 ] Intelligent judgment for authenticity determination or pass / fail judgment comprehensively in component appraisal, considering again the stamp appraisal information centered on the surface condition information of the money to be appraised obtained in 3-4 of the special engraving appraisal This is a process of presenting information to a money appraiser. Intellectual judgment information for authenticity judgment or pass / fail judgment in component appraisal is finalized by a specialized component appraiser based on analysis results and preliminary judgment information presented by a computer using an interactive system using a computer. The intellectual judgment process is strictly performed and presented to the money appraiser. If the result is clear (eg, it is clearly a defective product or a counterfeit product), it may not require an intellectual judgment by a specialist component expert. In addition, a specialized component appraiser may directly process information and present intelligent judgment information without using a computer interactive system. A money appraiser who creates and issues an appraisal and guarantees the appraisal results is In the process of issuing a monetary component appraisal, it is necessary to make a final conclusion by carefully confirming the judgment information regarding the component appraisal presented in this step.

[6] Issuance of money stamp appraisal ([3] Issuance of “monetary stamp appraisal” from the money appraiser based on the special stamp appraisal) (step S6)
The money stamp appraisal certificate guarantees the appraisal result by describing the result of rigorous money appraisal from the external information (basic money stamp information and surface condition information, etc.) of the money to be appraised. . Information for judging and determining the appraisal result regarding the authenticity or quality of the final stamp is 3. Specialized stamp appraisal 3-1 and 3-3 are the main constituents, and grade evaluation and the like are mainly [3] Professional stamped appraisal 3-4. Basically, if it is judged as NG (defective or counterfeit) in any one of 3-1, 3-3, in principle, an evaluation as a genuine product cannot be obtained in the stamping appraisal. In order to be evaluated as a genuine product, in principle, it is necessary to determine that both 3-1 and 3-3 are OK.

However, even if 3-1 and 3-2 are regarded as defective, if a professional money stamp appraiser determines that the determination result includes uncertainty, [5] the result of expert component evaluation After that, the final judgment may be carried out with reference to the information, or the final authenticity determination result may be left to the final component appraisal result in [7] issuance of the monetary component appraisal report. obtain.
In general, there are many cases in which a money stamp certificate is issued only for non-defective products and genuine products. In this embodiment, as shown in 6-1 and 6-2 of FIG. 1, when there is no abnormality in the money, the money stamp certificate that proves that the money is genuine and the grade is displayed. If there is an abnormality in the money issued, issue a money stamp certificate that proves that there is an abnormality in the stamp identification and the grade. As a result, the value of the genuine product is guaranteed and the asset value is maintained and improved, and the defective product and the counterfeit product are prevented from being distributed as a genuine product again.

[7] Issuance of monetary component appraisal report ([5] Expert component appraisal, in particular based on “presentation of analysis and intelligent judgment information based on component measurement information and surface condition information (5-3)” Issue “Money Component Certificate” (Step S7)
The monetary component appraisal report is the result of rigorous monetary appraisal from information on the components constituting the monetary subject of appraisal (especially, information obtained by measuring and analyzing elemental components in the vicinity of the monetary surface in consideration of state information in the vicinity of the monetary surface). This guarantees the appraisal result. The information for judging / determining the appraisal results regarding the authenticity or quality of the final target currency component is mainly based on the judgment information of [5] Expert component appraisal 5-3. Use the result information with reference or reconsideration. Basically, if it is judged as NG (defective or counterfeit) in 5-3, an evaluation as a genuine product cannot be obtained in principle for component identification. In order to be finally evaluated as a genuine product, in principle, it is determined to be OK in 5-3, and it is also necessary to be determined to be OK in 3-1 and 3-3 of the professional stamp appraisal.

  However, if it is regarded as a genuine product by the professional engraving appraisal and it is regarded as defective in 5-3 of the professional component appraisal, the expert monetary component appraiser will indicate that the judgment result of the component appraisal includes uncertainty. If it is judged, from the standpoint of not mistaking a genuine product as a counterfeit product as much as possible (no punishment for suspicion), [3] give priority to the results of professional stamping appraisals, and first distribute them as authentic products based on the results of stamping appraisals It is advisable to recommend re-appraisal after the appraisal technology for the engraving and composition of money in the future advances. In addition, [3] Uncertainty is included in the professional stamping appraisal (there are problems such as questionable products or elements that cannot be judged as good or bad on the stamping appraisal) and [5] expert component appraisal. Even if it is considered that there is no problem in the judgment of 5-3, if it is judged that it is a non-defective product in the case of issuing a monetary component certificate after stating that fact, or if it can be judged that the component component is a good product A stamp certificate may be issued.

  Issuance of a monetary component certificate is basically performed for both non-defective and defective products. In this embodiment, as shown in 7-1 and 7-2, when there is no abnormality with respect to the component of money, the monetary component certificate that proves that the money is a non-defective product or has no abnormality. If there is an abnormality in the component of money, issue a money stamp certificate that proves that it is a defective product or has an abnormality. As a result, in cooperation with the stamped certificate, the rigorousness, reliability, and reliability of the money appraisal will be further improved, and the value of non-defective products and genuine products will be guaranteed at a high level to further increase the asset value. In addition to the increase, it is possible to obtain an effect of preventing defective products and counterfeit products from being distributed again as genuine products.

  As described above, in [1] to [7], the detailed description of the embodiment of the present invention according to FIG. 1 has been made. Based on the component database classified as an index, the surface condition information of money described in [2] of [5], it was obtained in a form that comprehensively expressed the nature and characteristics of the database. An example of how to obtain a basic evaluation formula for an evaluation function (component evaluation function for estimating a specific component) will be described below.

(A) Statistical analysis and analysis of a plurality of money components of the same kind belonging to a database of a certain classification, and the composition ratio of notable element components detected from the vicinity of the surface of the money, etc. What kind of relationship (for example, what kind of compound is formed with other components and what ratio should be detected if it is a non-defective product) Approximate function (estimated evaluation function) with variable parameters estimated from information, surface state information, etc., and component values of other components, year (such as the year in which money was manufactured), and numerical values of surface state information ) And then estimating the necessary coefficient parameters of the function by statistical processing to complete the objective evaluation function. For example,
Variable parameter of component ratio of elemental elements to be noted = y,
Variable parameters of composition ratios of other element components = x0, x1, x2, x3, x4, x5, x6, x7,
Weighting coefficient parameters for adjusting the composition ratio = a0, a1, a2, a3, a4, a5, a6, a7, b0, b1, b2, b3, b4
Year era parameter at the time of manufacture = p,
The Christian calendar parameter at the time of appraisal = q,
y (xn) = a0 * (x0-b0) + a1 * (x1 + x2-b1) + a3 * (x3 + x4-b2) + a4 * (a5 * x5-x6-b3) + a6 * (x7-x7 * a7 (p-q) + B4)
As described above, the function y (xn) for deriving the variable parameter y of the element to be noticed by the variable parameter xn of the constituent ratio of the element is analyzed by analyzing the database by a statistical processing method, and the form of the function (approximation) For example, weighting coefficient parameters and calculation evaluation results that include all the money that can be regarded as non-defective components in the database (the calculation result of this function is an evaluation result that can be regarded as non-defective) (A variation range in which the value of y derived by this function can be regarded as a non-defective product) is determined.

  Thus, for example, in this example of the evaluation function, when the element component composition ratio x0 � x7 of the money is substituted into the evaluation function of the component database estimated to belong to a certain appraisal target money, the composition estimated value y of the element of interest is obtained. If the currency to be appraised is a defective product, in many cases, a y-value that is out of the range of the component estimated value y for the element of interest in the original good product is calculated. By calculating the y value within the range of the component estimated value y for the element, information that can be used for quality determination in the component identification is obtained.

(B) For a plurality of the same kind of money components belonging to a database of a certain classification, the composition ratios of notable element components detected from the vicinity of the surface of the money, etc., have any relationship with other detection components In a general-purpose function calculation formula (for example, using a mathematical series expansion such as an Nth order polynomial or a Fourier series), as in (a), the component values of other components Set a general-purpose evaluation formula that expresses in general terms what kind of relationship it is with other components, such as the year (such as the year in which the money was manufactured), the value obtained by quantifying the surface state information, etc. There is a method of solving a simultaneous equation using a computer or a numerical calculation such as a convergence calculation to solve or approximate a necessary coefficient parameter to complete a target evaluation function. For example, for a component database with the currency of a group with a certain surface state of a certain year as the population,
Variable parameter of component ratio of elemental elements to be noted = y,
Variable parameters of composition ratios of other element components = x0, x1, x2, x3, x4, x5, x6, x7,
General coefficient parameters = a0, a1, a2, a3, a4, a5, a6, a7,
y = Σa0n × x0 ^ n + Σa1n × x1 ^ n +... ΣΣa7n × x7 ^ n
As described above, a general-purpose function y (xn) for deriving the variable parameter y of the element of interest is set by the variable parameter xn of the element composition ratio, and the component data of each currency belonging to the database is substituted for xn. A general-purpose coefficient parameter an is obtained by analysis using a numerical analysis method, and the shape of the function (an approximate solution may be used) is estimated. For example, general-purpose coefficient parameters that include all the money that can be regarded as non-defective components in the database (the calculation result of this function becomes an evaluation result that can be regarded as non-defective) and the range of calculation evaluation results (derived by this function) A variation range in which the value of y can be regarded as a non-defective product is determined. The subsequent usage is the same as (a).

  Here, as shown in the above (a) and (b), two examples of methods for deriving the evaluation formula are given. However, various comprehensive evaluation formulas for component identification can be set by the same method. In any case, if an evaluation function is derived in advance corresponding to each classified component database, all necessary evaluation functions can be obtained for an entire currency classification area, and comprehensive evaluation in component evaluation・ It can be used for judgment. In addition, in the process of actual component identification, component data of many good and defective products can be obtained, and each component database can be enriched for each identification.
