Coin conveyor for coin processing machines running between a coin collection zone and a coin delivery zone located above the coin collection zone, constituted by a channel that comprises: - A first coin reception segment, where the channel is defined by a longitudinally movable wall and by an opposite fixed wall, both converging towards each other towards the inside of said channel; - A second coin transportation and alignment segment, where the channel is defined by a longitudinally movable wall, by an opposite fixed wall and by an also fixed bottom; - A third coin separation segment, where the channel is defined by the lateral surface of a freely rotating cylindrical roller, by a longitudinally movable wall elastically supported on the lateral surface of said cylindrical roller along the length of an arch of approximately 90°, and by a fixed bottom; - A fourth coin delivery segment, where the channel is defined by a longitudinally movable wall and by an also fixed bottom, the second segment having means to drive the coins running along the same towards the bottom of said segment and the longitudinally movable wall of all segments being constituted by a single endless belt being mounted on pulleys (6-6') wherein - the third coin separation segment is located at a height above the first coin reception segment, the channel running between said segments with a backwards inclination in the ascending direction, while along the fourth segment, the channel runs longitudinally in the horizontal position - and a separation of two adjacent coins is achieved due to the inclination in the ascending direction of the channel, and to the separation of the movable wall from the cylindrical roller when the first of the two adjacent coins is at the beginning of the path on said cylindrical roller. - A first coin reception segment, where the channel is defined by a longitudinally movable wall and by an opposite fixed wall, both converging towards each other towards the inside of said channel; - A second coin transportation and alignment segment, where the channel is defined by a longitudinally movable wall, by an opposite fixed wall and by an also fixed bottom; - A third coin separation segment, where the channel is defined by the lateral surface of a freely rotating cylindrical roller, by a longitudinally movable wall elastically supported on the lateral surface of said cylindrical roller along the length of an arch of approximately 90°, and by a fixed bottom; - A fourth coin delivery segment, where the channel is defined by a longitudinally movable wall and by an also fixed bottom, the second segment having means to drive the coins running along the same towards the bottom of said segment and the longitudinally movable wall of all segments being constituted by a single endless belt being mounted on pulleys (6-6') - the third coin separation segment is located at a height above the first coin reception segment, the channel running between said segments with a backwards inclination in the ascending direction, while along the fourth segment, the channel runs longitudinally in the horizontal position - and a separation of two adjacent coins is achieved due to the inclination in the ascending direction of the channel, and to the separation of the movable wall from the cylindrical roller when the first of the two adjacent coins is at the beginning of the path on said cylindrical roller.
