This is a general term for the entire device for sequentially transporting the medals D by tying them together. First, the medal transport device 6 that connects the overflow medal storage tank 130 and the unwashed medal storage tank 510 on the game island 1 will be described. The overflow medal storage tank 130 has an overflow medal collection hopper 131 having a structure similar to the washer supply hopper 512 in the unwashed medal storage tank 510, and a medal delivery port 530 of the overflow medal collection ho 7h 131. A transport rail 601 is connected to the transport rail 601, and this transport rail 601 extends to the unwashed medal storage tank 510. The transport rail 601 is made of extruded aluminum titanium alloy, for example, and has a channel-shaped cross section, and is vertically long so that the medal D can be transported in an upright state. A convex portion 603 is formed on the rail portion 602, which is formed and serves as a passage for the medal D, so as to sandwich the medal D from the front and back. Incidentally, by forming the convex portion 603 in this way, the contact area between the medal D and the rail portion 602 is reduced,
Moreover, the gap formed eliminates resistance caused by dust and foreign matter, thereby reducing the coefficient of friction. In order to store the medals D compactly in a limited space and to transport the medals D efficiently, the transport rail 601 may be of a double-sided type as shown in FIG. 6(b). Furthermore, at a corner part 605 where the transport rail 601 bends from the horizontal direction to the vertical direction, or conversely from the vertical direction to the horizontal direction, the transport rail 601 itself is bent at right angles in appearance, but as shown in FIG. The rail portion 602 inside is in the shape of a circular arc with a constant radius. Further, on the same plane, the conveyor rail 60
In the direction changing unit 607 in which the medal D changes its direction, for example, when the diameter of the medal D is 251 times, the conveyor rail 601 needs to have a radius of curvature of about 1 m or more. A forced feeding device 610 is installed on such a conveyance rail 601.
is provided. This forced feeding device 610 is configured such that when the medals D are lined up on the transport rail 601, the downward force due to the weight of the medals D and the frictional resistance between the medals D and the rail section 602 are applied to the overflow medal collection hopper 131.
The purpose is to forcibly apply a drive to the medals D in the advancing direction in order to prevent the medal D from being unable to be supplied in the medal advancing direction by exceeding the force in the medal advancing direction due to the driving force of It is provided on the conveyance rail 601 as a. This forced feeding device 610 actually
It includes a holding plate 612 for attaching a feed driving section 611, which is a part that performs forced feeding, to the conveyance rail 601, and a connector 613 for connecting the feeding driving section 611 and the holding plate 612. The feed drive unit 611 is an L-shaped substrate 61
5 includes a motor M3, a gear head 616 for decelerating the rotation of the motor M3, and a pulley 618 attached to the output shaft of the gear head 616. Further, two O-rings 619 are wound around the boob 17618, and the medals D are sent when the O-rings 619 rotate in contact with the medals D.

The position where the O-ring 619 contacts the medal D is the fifth
As shown in Figure (b), the medal D is transported by the transport rail 601.
When conveying the medal D in the horizontal direction, it touches the top of the medal D, while when conveying the medal D in the vertical direction, it touches the center of the medal D. By the way, the reason why it touches the top of the medal D when conveying it in the horizontal direction is
Medal D is rotated so that it moves in the direction of movement.
This is in order to proceed efficiently. Further, a pressure regulator 620 is provided on the substrate 615.

As shown in FIG. 6(a), this pressure regulator 620 includes a flat cylindrical contact fitting 621 having a contact surface 622 on the side.

The function of the pressure regulator 620 will be described later. Further, the holding plate 612 is a channel-shaped member that can slide along the transport rail 601 so as to cover and grip the outside of the transport rail 601. A fixing screw 626 is provided. Further, the connecting tool 13 is a hinge-shaped metal fitting, which is provided with a spring 629 at a rotating portion 628 thereof. Incidentally, due to this spring 629, the O-ring 619 of the feed drive section 611 tends to be in pressure contact with the medal D at all times, using the rotating section 628 as a pivot point. Further, the pressure adjustment of the O ring 619 to the medal D is adjusted by the pressure adjusting tool 620. That is, the adjustment screw 624 in the pressure adjustment tool 620
is loosened, rotate the abutting metal fitting 621 eccentrically around the fixing screw 623 to connect the pulley 618 and the transport rail 6.
By adjusting the distance from the 0 ring 619
In order to adjust the pressure on the medals D, the part where the pulley 618 faces the transport rail 601 is designed to prevent the medal D from wearing against the rail part 602 due to the tendency of the pulley 618 to press against the rail part 602. A wear prevention plate 630 made of a metal plate such as an iron plate or a stainless steel plate is provided. Next, the medal transport device 6 from the unwashed medal storage tank 510 to the control box 550 will be explained.

When the medal D advances from below as shown in , the steel ball 643 is pushed up and escapes to the upper part of the storage section 642, and the medal D advances upward through the gap created thereby. In addition, in this way, when the medal D that has moved upward is about to fall downward, the steel ball 643 returns to the lower part of the storage section 642, thereby blocking the passage of the medal D and preventing backflow. . The backflow prevention mechanism 640 is installed not only directly above the medal delivery port 563 in the medal supply hopper 562, but also directly above the overflow medal collection hopper 131 or the forced feeding device 610.
It may also be provided directly above the. Further, a forced feeding device 610 is provided where the conveyance rail 601 exits from the control box 550, and a backflow prevention mechanism 640 is provided directly above the forced feeding device 610. Furthermore, a sensor 645 is provided on the transport rail 601 before reaching the game island 1. Incidentally, this sensor 645 detects that the medal D is not present on the transport rail 601, converts this information into a signal, and sends the signal to the control unit 570. The control unit 570 drives the medal supply hopper 562 based on this signal to supply medals D. Also, to explain the medal removal device 6 disposed at the upper part of the game island 1, a conveyor rail 601 is provided at the upper part of the game island 1, and this conveyor rail 6

A medal chute tube 650 is also provided between the transport rail 601 and the medal lending v&2, and a medal replenishment shutter 660 similar to that described above is provided at the connection portion thereof.

The medal management system in a medal gaming facility such as a slot machine, which is the present invention, has the structure described above.The flow of medals D in this system and the operation of each component at that time will be explained below. First, in the slot machine 101, the upper hopper 108
The medals D are stored in the display screen 109 as a result of the game.
When all the patterns are aligned, the upper hopper 108 to the saucer 110
Medal D will be paid out. When the amount of medals D in the upper hopper 108 decreases in this way, the sensor 1
12 detects this, the shutter 662 in the medal replenishment shutter 660 is opened, and the medals D are replenished. Note that when the shutter 662 is opened and closed, the medal D may get caught between the conveyance rail 601 and the shutter 662. In such a case, the motor M4 in the replenishment shutter 660 is continuously driven until the limit switch 675 for stopping shutter operation is activated. Also, if the limit switch 675 does not work even with this operation, the main storage tank 560
By instantaneously driving the medal supply hopper 562, the motor M4 is continuously driven while pushing out the medals D, and the shutter 662 is repeatedly closed, thereby automatically resolving the trouble. desirable. Further, the medals D inserted by the player are once collected in the lower hopper 106 and then transferred to the upper hopper 108. Further, an upper hopper 108 and a lower hopper 106
When the amount is full, the medals D inserted thereafter pass through the overflow chute pipe 115 to the recovery conveyor 102 and are conveyed to the overflow medal storage tank 130, as described above. Further, the medals D counted by the medal counter 3 provided next to the game island l are also temporarily collected in this overflow medal storage tank 130. In this way, overflow medal storage tank 1
The medals D gathered at 30 are sent onto the transport rail 601 by the drive of the overflow medal collection hopper 131, and are driven by the forced feeding device 610 midway through to the unwashed medal storage tank 510. The unwashed medal storage tank 510 also stores medals D counted by the medal counter 3 installed thereon. Next, the medals D stored in the unwashed medal storage tank 510 are transferred to the medal washer 4 by driving the washer supply hopper 512.
After being washed there, the medals are sent to a washed medal storage tank 540. Thereafter, the medals D are transferred to the main tank body 561 in the control box 550 by driving the washed medal transport hopper 542 and stored therein. In the main tank body 561, a medal supply hopper 562 is driven by a signal from a sensor 645, and an appropriate number of medals D are transported to a transport rail 601 leading to the game island 1. As a result, the transport rail 601 in the upper part of the game island 1 is always filled with medals D. After the medals D are used in the slot machine 101 in this manner, they are automatically transported, washed, and stored, and then used again in the slot machine 101.
