A coin receiving/dispensing machine where an increased number of coins can be received. This is achieved by reducing that space above a passage which is required for coin conveyance, reducing the size of a machine body (11), and allocating the reduced space for a receiving/discharge section (27). An endless conveyance belt (72) is stretched over an identification path (22) and a classification path (23) by pulleys (71) horizontally rotatably supported by vertical shafts (71a). That space above the passage which is required to place the conveyance belt (72) is reduced, the machine body (11) isreduced in size, and the reduced space is allocated for receiving/discharge section (27). All of these contribute to increase the number of coins receivable in the machine.
