PURPOSE:To obtain a counting device without executing the erroneous counting to the mixing of foreign matters by using a color classified sensor. CONSTITUTION:A detecting part main body 1 is provided with a pipe 5, and is shaped of a perforated plate, and a cleaning body 6 and mixed foreign matters 7 pass through an aperture part together with a water flow. A color classified sensor 2 is arranged vertically to the aperture part of the detecting part main body 1, the cleaning body 6 to pass through the aperture part is detected by the color and the detected signal is sent to an arithmetic part 3. The body is transferred from the arithmetic part 3 to a displaying part 4 and the number of the passing of the cleaning bodies is displayed. Thus, only the cleaning body can be detected and counted, and therefore, the counting error can be eliminated.
