A coin selector prevents illegal actuation of a coin sensor for real coin detection and is reduced in size and has a high coin processing rate, and which can cancel a coin to be cancelled reliably. The coin selector detects the passage of a coin based upon a signal from a coin sensor disposed downstream of a real/fake discriminating unit formed along a coin passage through which the coin moves. A moving direction changing unit for a coin is provided on the coin passage downstream of the real/fake discriminating unit and the coin passage downstream of the moving direction changing unit is disposed on a plane different from a plane on which the moving direction changing unit is present.
