<p>An apparatus for checking coins (2) as to whether they are genuine coins of a preselected denomination or not, comprising a chute (3) along which coins (2) are fed one by one by transport means (9, 10), camera means (7, 8) for imaging each coin and producing an image signal representative of the image of the coin, and control means (13) for judging, in response to the image signal, whether each coin is genuine or not. For accurately checking the coins even if they are stained or dust covered, a plurality of slits (4a-4d,) are formed in a prescribed pattern in the chute (5) intermediate the opposite ends thereof, and a dark box (5) is disposed on one side of the chute for providing an optically dark space which is open to the slits in the chute and in which a coin sensor (6) is disposed. Thus the coin sensor can optically sense each coin traveling over the slits, whereupon camera means (7, 8) are actuated for imaging the coin over the slits. <IMAGE></p> |
