It has a bridge circuit in which the diagonal voltage becomes 0 only when genuine coins among rolling coins pass the side of the sorting coil. In a coin sorting device, the diagonal voltage generated in the bridge circuit is changed by changing the diagonal voltage generated in the bridge circuit, and the material of the coin is detected according to the change to determine whether the coin is genuine or false. The sorting coil is composed of a ring groove, a ferrite pot core having a center core inside from the ring groove, and a coil housed in the ring groove. The height of the center of the sorting coil above the coin rail is positioned so that it is guided between the concentric circles of the outer circumferential circle that the coin passes through, and authenticity can be detected by checking whether or not the coin is perforated. do.

FIG. 4 shows such measurement results, where the horizontal axis shows the changed value of l, and the vertical axis shows the diagonal voltage V. As is clear from this figure, the diagonal voltage V is at its peak value when l is equal to the radius a of the center core 16 to a value a+h/2, which is the radius a plus half the width h of the groove 12. shows. That is, the center O of the center core 16
The position of l=a~a+ with respect to the coin center O A
Perforated 50 yen coin 3 which is specie when set to h/2
In the case of A, the diagonal voltage V is 0, whereas in the case of counterfeit coins, the diagonal voltage of the most significant magnitude is obtained.
The position of the sorting sensor 5 is selected so that the center O of 6 is located, thereby making it extremely easy to eliminate counterfeit coins.
