摘要

A method and apparatus for discriminating coins or bank notes, in which sensors measure characteristics of coins or bank notes. Processing control apparatus provides a reference value setting mode and a discrimination mode. In the reference value setting mode, data of sample coins or bank notes obtained from the sensors are statistically processed to calculate minimum and maximum reference values, and these values are stored in a memory. In the discimination mode, a coin or bank note to be authenticated is checked as to whether its characteristics are within the range of minimum and maximum reference values. Genuine coins or bank notes are automatically separated from counterfeit.
