Abstract
A sensor is used for the recognition of coins, which analyses the mintage. The main component of the sensor is a polymeric, elastic material (20) which has piezoelectrical properties. By pressing the minted face of a coin onto the sensory surface (23) a signal is produced corresponding to the high and low points of the mintage, which permits an assessment of the coin by means of the connection of an electronic evaluation unit.
Claims11
A device for the recognition of coins, in particular for the grading of authorized and non-authorized minted coins having at least one minted surface comprising a converter consisting of a polymeric, elastic material with piezoelectric properties and having a sensory surface, means for pressing a minted surface of a coin against said sensory surface to generate a piezo electrical signal, means for converting the piezoelectrical signal of the impression pattern of the coin's minted surface to establish a characteristic electrical signal for the coin and means for evaluating the electrical signal.
