  • Device with a sensor for the recognition of coins
    Patent number: 4726458
    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.
