Zusammenfassung:	PROBLEM TO BE SOLVED: To exactly and quickly judge the necessity of the cleaning a roller, etc., by pressing a card with a prescribed pressing force via a holding means holding the card. SOLUTION: When a card C part is inserted into a card fetching port, a roller for carrier is rotated and the roller is going to fetch a card C. If this card fetching force is larger than the pressing force generated between a rubber pad P and a projection roller 31, the projection roller 31 is rotated, the card C is fetched into a card reader, and it can be judged that this fetching force is excellent and the cleaning of the roller, etc., is not necessary. Conversely, if the card fetching force is smaller than the pressing force generated between the rubber pad P and the projection roller 31, the card C is not fetched into the card reader and the fetching operation is stopped after a prescribed time. In this case, it can be judged that the fetching force is defective and the cleaning of the roller, etc., is necessary.
