To check whether a coin is true or false and to cancel a false coin by arranging a check means, with which whether a disk object is true or false is discriminated, on the upstream side of a passage means for the disk body to be fed out and arranging a gate means to be controlled by the check means on the downstream side of the passage means.

When medals are piled up inside a tank 21 in pieces and a disk 22 is rotated, the medals are piled up inside a through hole 25 on the rotating disk 22, and the lowest medal is moved on a base plate 11 while sliding and forcedly fed out to the upstream of a passage 33 one by one by a projecting arm. The medal pushed out to an inlet above the passage 33 falls through the passage 33, and a check means 35 discriminates whether the passed medal is true or not. When the medal is true, the upper edge of a gate means 38 rises, an aperture 39 opens, and the medal falls down. In case of false medal, the gate means 38 is not operated, and the dummy medal 1 is passed through the passage 33 to the bottom and housed in a case for cancel or the like.
