    • A coin validating apparatus having a coin carriage for moving the coin along at least one coin track. The coin carriage has at least an electrically conductive portion in contact with the coin. The coin track has at least one cam at a predetermined location, the cam having at least a substantially non-conductive base portion attached to the coin track and an electrically conductive top portion. A component for detecting current is connected in series with the top portion in a first terminal of a voltage souorce. A second terminal of the voltage source is connected to the electrically conductive portion of the coin carriage. The coin completes an electrical connection between the electrically conductive portion of the coin carriage and the top portion of the cam when the coin carriage has positioned the coin over the cam and when the coin is electrically conductive. When the coin comnpletes the electrical connection, the component for detecting provides a signal indicative thereof.
    • 一种硬币验证装置,具有用于沿着至少一个硬币轨道移动硬币的硬币托架。 硬币托架至少具有与硬币接触的导电部分。 硬币轨道在预定位置具有至少一个凸轮,所述凸轮至少具有连接到硬币轨道的基本不导电的基部和导电顶部。 用于检测电流的部件与电压源的第一端子中的顶部部分串联连接。 电压源的第二端子连接到硬币托架的导电部分。 当硬币托架已经将硬币定位在凸轮上方时以及当硬币是导电时,硬币在硬币托架的导电部分和凸轮顶部之间完成电连接。 当硬币连接电气连接时,用于检测的部件提供指示其的信号。
