DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin dispensing apparatus for dispensing coins while counting coins in a gaming machine using coins as a game medium, such as a slot machine, a currency exchange machine, a vending machine, and the like.

[0002]

2. Description of the Related Art As shown in FIG.
It is composed of a holding tank A for storing coins, a payout section B for paying out coins in the holding tank A one by one while aligning the coins on the same surface and counting the number of coins, and a base C for supporting them. . In the previous coin dispenser, the holding tank A
Is made of plastic, and the payout portion B and the base C are made of metal. However, recently, the payout portion B has been formed of plastic in order to reduce processing costs and reduce weight.

FIG. 3 is a view showing a payout section of a conventional coin payout apparatus. In FIG. 3, 1 is a base, 2 is a payout rotor, 3 is a coin inlet, 4 is an inclined portion, 5 is a coin guide, 6 is a movable roller, 7 is an opening, 8 is a guide member, and 9 is a guide member 8. Set screw for fixing to base 1, 10
Is a payout port, and 11 is a count sensor.

The movable roller 6, the guide member 8, and the set screw 9 are made of metal to prevent abrasion and the like, but other parts such as the base 1, the payout rotor 2 and the like are made of plastic. The payout rotor 2 sequentially receives the coins held in the above-mentioned holding tank A into the coin inlet 3 while rotating in the direction of the arrow by a motor (not shown). that time,
An inclined portion 4 is formed on one side of the coin inlet 3 so that coins can be easily introduced into the coin inlet 3 in a horizontal state.

A coin inlet 3 is provided on the lower surface of the payout rotor 2.
A guide claw (not shown) is provided to push out the entered coin in a direction away from the rotation axis of the payout rotor 2. The coin slides on the base 1 and rotates while the coin guide 5 rotates.
Move along. When reaching the position of the guide member 8, the movable roller 6 guided in the direction of the payout port 10 and pushed by the spring is pushed in the direction of the opening 7 and passes through the movable roller 6. It is discharged in the direction of the payout port 10 by force. At this time, the number of coins discharged is counted by the count sensor 11, and when the number of coins to be paid out is reached, the rotation of the payout rotor 2 is stopped, and the payout of coins is stopped.

In such a coin dispensing apparatus, since the holding tank A and the dispensing portion B are almost entirely made of plastic, the friction between the coin stirred and the holding tank A and the dispensing portion B is increased. There is no way to escape the static electricity generated in the process, and the static electricity is accumulated inside. As a result, when the coin passes through the count sensor 11, a spark is generated between the coin and the count sensor 11, causing the count sensor 11 to malfunction and causing an error in the count value.

Therefore, in the conventional coin dispensing apparatus, through holes 12 are formed at appropriate intervals in a portion of the base 1 which is below the orbit of the coin introduction port 3 of the dispensing rotor 2, and the contacts 13 are disposed therein. , Each contact 13 is grounded via the base C. As a result, the coin entering the coin inlet 3 comes into contact with the contact 13 and the static electricity generated by the friction is released to the outside, thereby preventing the occurrence of the spark as described above.

[0008]

However, in such a coin dispensing apparatus, when coins enter the coin introduction port 3, they do not always enter in a parallel state, and a plurality of coins stand in a standing state. The coin may enter the coin introduction port 3 and receive the pressure of a large number of coins remaining in the holding tank A, so that the coin may be left in the vertical direction. In such a state, the coin cannot contact the contact 13 and the static electricity cannot be released. Even if the static electricity disappears while it is inside the payout rotor 2, even after passing between the guide member 8 and the movable roller 6, static electricity is generated due to friction, which also causes a spark. As described above, the conventional coin dispensing apparatus has a problem that the effect of removing static electricity cannot be sufficiently obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to solve such a problem and to reliably remove static electricity with a simple structure and to reliably prevent generation of sparks.

[0010]

According to a first aspect of the present invention, there is provided a coin dispensing apparatus in which a holding tank for accommodating a large number of coins and coins held in the holding tank are introduced. A plurality of coin introduction ports are provided, a disc-shaped dispensing rotor that pushes the introduced coin to the outer peripheral side while rotating, and a coin that is disposed below the dispensing rotor and the coin introduced into the coin introduction port is disposed on an upper surface. Receiving a plastic base, a metal guide member for guiding coins pushed out from the payout rotor toward the payout port, and a payout unit having a count sensor for detecting coins discharged from the payout port, A coin dispensing device including the holding tank and a metal base supporting the dispensing unit, wherein the guide member is electrically grounded. In this case, static electricity can be reliably removed, and generation of spark can be reliably prevented.

The coin dispensing device according to a second aspect of the present invention is characterized in that a metal screw for fixing the guide member is screwed into the base. With this configuration, the guide member can be reliably grounded with a simple structure.

The coin dispensing device according to a third aspect of the present invention is characterized in that the guide member is extended to a position facing the count sensor. This way,
Static electricity generated after being extruded from the dispensing rotor can also be reliably removed.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram illustrating a payout unit of the coin payout device. The reference numerals correspond to those in FIG. 3, and CO is a coin.

As in the conventional coin dispenser shown in FIG. 3, the movable roller 6, the guide member 8, and the set screw 9 are made of metal, but the other parts such as the base 1, the dispensing rotor 2 and the like are made of plastic. To improve workability and reduce weight. The guide member 8 is fixed to the base 1 with a metal set screw 9 as shown in FIG. 2, and the set screw 9 penetrates the base 1 and folds the upper portion of the metal base C. It is screwed into a bent base receiving part. In order to be able to receive the set screw 9 in such a manner, the base receiving portion of the base C bends the upper part of the metal plate forming the base C in parallel with the lower surface of the base 1 and the guide member 8 It is extended to the position of the screw hole for the set screw 9.

As a result, the guide member 8 is electrically connected to the base C via the set screw 9 by screwing the set screw 9 into the base receiving portion of the base C. Since the base C is electrically grounded through a casing of a game machine or the like to which the base C is attached, the guide member 8
Is electrically grounded.

In such a coin dispensing apparatus, the dispensing rotor 2 sequentially receives coins held in the above-mentioned holding tank A into the coin introduction port 3 while rotating in the direction of the arrow by a motor (not shown), and dispenses them. A guide claw (not shown) provided on the lower surface of the rotor 2 pushes the coin entering the coin inlet 3 to the outer peripheral side while rotating, and moves the upper surface of the base 1 along the coin guide 5. . When the coins reach the position of the guide member 8,
The movable roller 6 guided in the direction of the payout port 10 and urged toward the coin by a spring (not shown) is pushed in the direction of the opening 7. When the coin passes through the movable roller 6, the coin is discharged vigorously in the direction of the payout port 10 by the force of the spring. At that time, the number of coins discharged is counted by the count sensor 11.

As described above, the coin is guided in the direction of the payout port 10 while being pressed against the guide member 8. Therefore, coins discharged from the payout port 10 are always discharged through the count sensor 11 after coming into contact with the guide member 8. As a result, even if coins are rubbed against the holding tank A and the dispensing section B and static electricity is generated, the static electricity is removed through the guide member 8, the set screw 9 and the base C. Also, other coins in the holding tank A and the payout section B are in contact with each other and are electrically connected to the coins in contact with the guide member 8, so that all generated static electricity is removed. Is done.

Further, the guide member 8 is connected to the count sensor 1.
By forming the shape so as to extend to a position opposed to 1, the static electricity generated by the coin rubbing against the base 1 after being pushed out from the payout rotor can be reliably removed. As a result, the static electricity charged on the coin is completely removed, and it is possible to reliably prevent a spark from being generated between the coin and the count sensor 11 when the coin passes through the count sensor 11.

[0019]

Since the present invention is configured as described above, it has the following effects. That is, in the coin dispensing device according to the first aspect, since the guide member with which the coin discharged from the dispensing portion is securely in contact is made of metal and grounded, the static electricity is reliably removed from the discharged coin. However, the generation of spark can be reliably prevented.

In the coin dispensing device according to the second aspect, the metal screw for fixing the guide member is screwed into the metal base, so that the guide member is securely grounded with a simple structure. Can be done.

Further, in the coin dispensing device according to the third aspect, the guide member is extended to a position facing the count sensor, so that the static electricity generated after being pushed out from the dispensing rotor can be reliably removed. .
