Is a round belt, and is stretched between a pulley 52 that is rotatably supported above the inlet of the introduction passage 12 and a pulley 53 that is supported above a position downstream of the selection passage 12,
A belt portion facing the passage surface is urged downward by a plurality of rollers 54. The conveyor belt 51 is a pulley.
By the urging means for urging the rollers 52 and 53 and the roller 54 downward, the coins are normally supported at a height smaller than the minimum thickness of the coin with respect to the passage bottom surface 15, and the coin has entered under the conveyor belt 51. At times, the coin can be raised to the coin height with respect to the passage bottom surface 15, and is rotated by a motor (not shown) that drives the pulley 53 on the downstream side.

Further, a receiving member 61 for receiving coins having a predetermined diameter discharged through the sorting passage portion 13 is arranged at a position downstream of the sorting passage portion 13.

Next, the operation of this embodiment will be described.

When the turntable 1 is rotationally driven in the direction of the arrow in the figure, the coins supplied on the turntable 1 rotate together with the turntable 1 and due to the action of centrifugal force due to the rotation of the turntable 1. One coin in the thickness direction, which moves to the peripheral edge of the turntable 1 and moves along the inner surface of the peripheral wall 3 and contacts the turntable 1, passes under the thickness regulating member 5.

The coin passing under the thickness regulating member 5 enters the introduction passage 12 of the sorting passage 11 and is gripped under the rotationally driven conveyor belt 51. The conveyor belt 51 stretches the belt. After being forcibly conveyed in the direction, the one side edge of the coin abuts against the reference introduction passage wall 18, and then the reference introduction passage wall 18
While being moved inwardly of the passage along the inclination of the wall portions 18c and 18d, the sheet is conveyed to the downstream side and enters the sorting passage portion 13.

The coins that have entered the sorting passage portion 13 are conveyed along the reference passage wall member 22a by the conveying belt 51.
When the coin to be conveyed is a coin having a predetermined diameter, the coin passes through the side without contacting the large-diameter coin detecting member 31, and the edge between the wall members 22b and 23 on both sides is a guide edge. 29a
, 29b, 30 are passed over the sorting groove hole 28, discharged from the terminal end of the sorting passage portion 13 into the receiving member 61, and sorted.

When the coin to be conveyed is a small-diameter coin, the coin is conveyed toward the upper side of the sorting slot 28 without passing through the large-diameter coin detecting member 31 like the predetermined-diameter coin. However, when it reaches above the sorting slot 28, the other side edge is guided by the guide edge 30.
Since it comes off, it falls from the sorting slot 28 and is eliminated.

When the coin to be conveyed is a large-diameter coin, the lower surface of the other side edge portion comes into contact with and pushes down the large-diameter coin detecting member 31, interlocking with the downward movement of the large-diameter coin detecting member 31. The large-sized coin removing member 38 advances from the outside of the passage into the inside of the passage. Therefore, one side edge of the large-sized coin contacts the large-sized coin removing member 38 and moves to the sorting groove hole 28 side, and one side edge of the large-sized coin is disengaged from the guide edges 29a and 29b, and the sorting groove hole is formed. Dropped from 28 and eliminated. At this time, since the other side edge portion of the large-sized coin rides on the inclined surface 26 of the passage wall member 23 on the other side in the passage width direction, the posture of the large-sized coin is inclined so that one side edge portion is lowered and the other side edge portion is raised. Then, the coin with a large diameter is surely dropped into the sorting groove hole 28 from one side edge portion.

As described above, since the large-sized coin removing member 38 is mechanically interlocked with the large-sized coin detecting member 31 which is pushed down by the large-sized coin itself to remove the large-sized coin, the response is good and the speed is increased. Can be surely eliminated.

As described above, the small-diameter coin is automatically selected from the relationship between the diameter of the small-diameter coin and the groove width of the selecting groove hole 28.
The large-sized coin can be reliably excluded from the sorting groove hole 28 by the large-sized coin removing member 38 that works in conjunction with the large-sized coin detecting member 31, and only coins of a predetermined diameter pass through the sorting groove hole 28 and are a receiving member. It can be released to 61 for sorting.

The transport means is not limited to the transport belt, and the rollers may be continuously disposed above the path to transport.

[0034]

According to the present invention, when the large coin detecting member is pushed down by the lower surface of the large coin, the large coin removing member moves in conjunction with the downward movement of the large coin detecting member from outside the passage. Since it moves into the passage and one side edge of the large-diameter coin on the side of the reference passage wall member moves to the sorting groove hole, the large-sized coin can be reliably excluded in the sorting groove hole, and only coins with a predetermined diameter can be reliably sorted. it can.
