Abstract:
A coin validation apparatus with liquid evacuation, such as for use with a pay telephone, that effectively evaluates an inserted coin is described. A first arrangement of this apparatus comprises a coin path for receiving the coin and a liquid separator positioned along the coin path that separates liquid from the coin as the coin advances within the coin path. The coin validation apparatus further comprises a plurality of liquid channels operative to transport liquid from the coin path and a sensor array assembly positioned to evaluate the coin after the coin has passed said liquid separator. At least one drain in fluid communication with the plurality of liquid channels and operative to transport liquid from the coin validation apparatus is also included. A method of evaluating a coin inserted in a coin operated apparatus is also described. The method includes the steps of separating a liquid from the coin as the coin advances along a coin path, transporting liquid away from the coin path, and evaluating the coin after separating liquid from the coin.
