<p>There is provided a method and apparatus for discriminating between true and false coins wherein a coin satisfying both the electrical success conditions at their lowest levels is regarded as a false coin, and a coin satisfying at least one of the two electrical success conditions at a high level is regarded as a true coin. A method of discriminating between true and false coins or the like by mounting a discriminating means relative to a predetermined passage along which a coin or the like to be discriminated passes, wherein true/false discrimination is carried out in accordance with whether or not the two or three different data detected from the coin and developed on a two- or three-dimensional coordinate system falls within a predetermined two- or three-dimensional function closed area. An apparatus of discriminating between true and false coins, having: a coin passage along which a coin to be discriminated passes; exciting units (11a, 12a, 111a, 112a, 113a) mounted relative to the coin passage for exciting the coin passing along the coin passage; detecting units (11b, 12b, 13 to 17, 111b, 112b, 113b, 124 to 130) for detecting the state of the coin excited by the exciting units; and a unit (CPU) for discriminating the coin between true and false in accordance with whether or not the data detected by the detecting units falls within a predetermined two or three-dimensional function closed area on a predetermined two or three-dimensional coordinate system. <IMAGE></p> |
