摘要
A coin selector has a coin passageway where coins are inserted. A magnetic sensor inspects the coins through the coin passageway, and generates an inspecting signal, which a controller evaluates to generate an acceptant or unacceptant signal responsively. A gate plate responds to the acceptant or unacceptant signal, and provides two chutes selectively with the inspected coins. An accepting chute passes acceptable coins. A returning chute returns unacceptable coins. A photo sensor detects the acceptable coins through the accepting chute, and generates a detecting signal. Counters are adapted to counting, respectively, the acceptant signal in increment and the detecting signal in decrement. The controller adds together two counts of the counters, evaluates a sum of the addition, and generates an error signal in accordance with the sum evaluation. The error signal is utilized for implication of possible deceit or imposture of a player who inserts the coins. IMAGE
