Abstract

PURPOSE:To improve the discrimination precision of coins and to simplify the structure. CONSTITUTION:Coins 9 which are sent in order, one by one, from a precedent- stage sending-in part are mounted on a flat belt 1 and conveyed in an array, and restriction frames 2A and 2B restrict the upward hopping and sideways deviation during the conveyance. Discrimination sensors 3 provided nearby above; and below the flat belt 1 detect whether the coins are genuine or false in the conveyance. When a coin 9 is false, a solenoid 4 operates, a dividing gate 6 hops up to make a guide surface 6a leave the top surface of the flat belt 1, and the coin is conveyed by the flat belt 1 as it is. When the coin 9 is genuine, the solenoid 4 does not operate and the dividing gate 6 is still close to the top surface of the flat belt 1, so the genuine coin 9 abuts on the guide surface 6a and is guided along it and distributed as shown by an arrow P, so that the coin is conveyed by a conveying means consisting of a passage 15, etc.
