Meanwhile, in the present invention, the color sensors 30 and 37 are used for pattern recognition for determining the winding type and the face of the banknote. In the conventional apparatus, an infrared sensor is used for the pattern recognition of the banknote. This infrared reflecting sensor has a weak response, which makes it difficult to recognize patterns, and the transmittance through which infrared rays penetrate banknotes is almost unchanged even if the pattern and color are different. to be.

Therefore, in the present invention, the color of the banknotes is determined using the color sensors 30 and 37, which is very effective in the paper ring recognition. And when determining the right of fouling of banknotes, banknotes are usually buried with various contaminants depending on the degree of use, and the degree of folding and contamination becomes a factor that changes the transmittance of light.
