Zusammenfassung:	PROBLEM TO BE SOLVED: To precisely detect a coin diameter irrespective of the fluctuation of a coin position. SOLUTION: The cross sections of a first detection sensor part 1 and a second detection sensor part 2, which detect radial direction data at both ends of a coin 15 transported along a guide 17, are formed in E shapes. The first detection sensor part 1 and the second detection sensor part 2 are arranged so that free end 16 sides in E shapes of the first detection sensor part 1 and the second detection sensor part 2 face each other. Exciting coils 3, first detection coils 4 and second detection coils 5 are wound round the first detection sensor part 1 and the second detection sensor part 2. The exciting coils 3 of the first and second detection sensor parts 1 and 2 are connected in series. The first detection coils 4 and the second detection coils 5 are connected in common phases and the first detection coils 4 and the second detection coils 5 become differential.
