Abstract
Abstract A method and apparatus for discriminating coins or bank notes are disclosed, which use sensors 3, 10, 17 for measuring characteristics of coins or bank notes and processing control means 23-32 capable of providing a reference value setting mode and a discriminating mode. In the reference value setting mode, data of sample coins or bank notes obtained from the sensors 3, 10, 17 are statistically processed to calculate minimum and maximum reference values, and these values are stored in a memory 28. In the discrimination mode, a coin or bank note is discriminated as to its authenticity through checks as to whether its characteristic data obtained from the sensors are within the minimum and maximum reference values.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
147 words
A method of judging the authenticity of coins or bank notes by measuring characteristics thereof, comprising the steps of : measuring the characteritaics of a predetermined number of sample coins or bank notes with sensor means ; calculating minimum and maximum reference values for discriminating authentic coins or bank notes from the measured values of the characteristics of said predetermined number of coins or bank notes storing the calculated minimum and maximum reference values ; measuring the characteristics of a coin or bank note to be discriminated with said sensor means ; checking whether the measured characteristic value of the inspected coin or bank note is within the minimum and maximum reference values to judge the coin or bank note to be authentic if the checked value is within the two reference values and counterfeit if the checked value is outside the range between the two values.
Claim 2
Independent Claim
147 words
A method of judging the authenticity of coins or bank notes by measuring characteristics thereof, comprising the steps of : measuring the characteritaics of a predetermined number of sample coins or bank notes with sensor means ; calculating minimum and maximum reference values for discriminating authentic coins or bank notes from the measured values of the characteristics of said predetermined number of coins or bank notes storing the calculated minimum and maximum reference values ; measuring the characteristics of a coin or bank note to be discriminated with said sensor means ; checking whether the measured characteristic value of the inspected coin or bank note is within the minimum and maximum reference values to judge the coin or bank note to be authentic if the checked value is within the two reference values and counterfeit if the checked value is outside the range between the two values.
Claim 3
Dependent Claim
