Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a banknote validating exchange device for a gaming device such as a slot machine that includes a coin reservoir for paying out to winners. Still further, the present invention relates to a banknote validating exchange device that accepts different types of banknotes and disburses valid and acceptable banknote change from the same coin storage to pay to the winner of a gaming device.

BACKGROUND OF THE INVENTION A typical gaming device, such as a slot machine, accepts one type of coin to play the game, and the accepted coins are stored in a coin hopper included in the machine. Winning game plays are randomly determined by the slot machine, which pays out coins to the winners from a coin hopper.

A typical slot machine accepts only one type of coin, so the player must have that type of coin to play the slot machine game. Casinos with slot machines typically employ staff to exchange banknotes for players at the slot machine if the player wishes to continue playing the game but does not have the appropriate type of coins. To avoid having to leave the slot machine. However, in large, busy casinos, slot machine players may encounter long waits for such exchange personnel.

Known money changers are not particularly useful for making money changes for slot machines. That is because money changers generally accept only one type of banknote and dispense different types of coins. Thus, a slot machine player must have a particular type of bill that is accepted by the changer in order to use the changer. Even if the player has the appropriate type of banknotes, the exchange machine will only pay out 5 or 5 coins of the type that can be accepted by the slot machine, so after playing a few games the player will have to exchange again. Requires.

(Means for Solving the Problems) The present invention overcomes the inconveniences of conventional slot machines and money changers as described above. The bill verification exchange device for slot machines of the present invention is integrated with the slot machine,
This eliminates the need for players to leave the slot machine when they need to exchange money. Furthermore, this installation accepts multiple types of banknotes, and pays exchange coins only with coins of types that the slot machine can accept for the banknotes.
To allow players to play the maximum number of games with their banknotes without requiring additional exchange.

The bill validating and exchanging device for a slot machine according to the present invention includes an input device that accepts coins input by a player to play a slot machine game. Coins are stored in a coin hopper that is controlled to pay out coins to slot machine winners and exchange banknotes. Bills entered into the device are received by a bill input device which is controllable to determine the validity and type of the input bill and to accept or reject the bill. The slot machine banknote confirmation/exchange device determines a winning game play of the slot machine, determines whether or not to exchange the banknotes input to the device, and controls the coin hopper to dispense coins to the winner. It includes a master processor that exchanges payment notes. A master processor is coupled to slave processors to communicate with each other. The slave processors are coupled to the bill input device and in conjunction with each other determine and communicate the type and validity of the input bill to the master processor.

In addition, the slave processor controls the bill input loading,
Accepts banknotes that should be exchanged and rejects invalid banknotes and valid banknotes that should not be exchanged as determined by the master processor.

The master processor further monitors the number of coins in the coin hopper and prevents the bill input device from accepting bills when the coin hopper has less than a predetermined minimum number of coins. The master processor also monitors the coin input device to ensure that no exchange is made after coins have been accepted, ie, a slot machine game is in progress.

The device of the present invention allows exchange for a number of different types of banknotes for the convenience of the slot machine player, and allows the player to leave the slot machine or require casino personnel to do so when he or she needs to exchange money. So you don't have to wait. Furthermore, for the convenience of the player, exchange is only made with coins of the same type as the coins accepted by the slot machine to play the game.

The operation of the bill validating exchange device will now be described with respect to the flowcharts of FIGS. 4A and 4B. Upon power-up of the device, system parameters are initialized at block 120. These parameters include hopper cutoff values for each bill type that bill validation unit 12 can accept. The hopper cutoff value represents the minimum number of coins required in the hopper 26 to disburse exchange silver for a particular bill type. In the bill validating unit 12 illustrated in FIGS. 1 and 2, hopper cutoff values are set for the following types of bills: $1, $5, $10, and $20.

After the mounting parameters are initialized, at block 122,
The slot machine's CPU 64 determines whether the machine can accept banknotes.

The device cannot accept banknotes if any one of the following conditions exists:

(1) The handle 22 of the slot machine has been pulled and the game is currently being played.

(2) The coin has been inserted and the game is about to begin.

(3i slot machine 10 or banknote confirmation unit 1
One of the two doors is open.

(4) The slot machine 10 is fixed at a win.

(5) The number of coins in the hopper is less than the cutoff value for the smallest denomination bill type that bill validation unit 12 can accept.

(6) The device is malfunctioning.

(7) The slot machine is tilted.

If one or more of these conditions are present,
The CPU 64 prevents the banknote verification unit 12 from accepting banknotes. If any one of states (3+, f51 to (7)) occurs, the CPU 64 further controls the coin input device 118 via the slot island buffer 114 and the slot tail board 116 to input coins into the slot machine 10. CPU 64 then sends programmable communication interface 68 to bill acceptor 52 .
The banknote type display 43 is erased by commanding the banknote type display 43 via the . The LED blocks forming each of the banknote types are thus not illuminated. CPU 64 then returns to block 122.

If the device is capable of accepting banknotes, as determined by block 122, the CPU 64 returns to block 128.
and reconfigures the bill acceptor 52 by instructing the bill acceptor 52 as to which bill types it can accept. Specifically, the CPU 64 checks the number of coins currently stored in the coin hopper 26 and compares this number with the hopper cutoff value for each bill type. If the number of coins in the hopper is greater than but equal to the cutoff value for a particular bill type, the CPU 64 instructs the bill acceptor at block 128 that the particular bill type can be accepted. Next, at block 130, CPU 64 determines whether coin input device 118 has accepted a coin. When the coin acceptance is completed, the CPU 64 executes block 1.
At 32, the slot machine game routine is executed. At the end of the slot machine game, as determined at block 134, CPU 64 returns to block 122 where it determines whether the machine is currently capable of accepting banknotes. If it is determined at block 130 that coins are not accepted, the CPU 64 polls the bill acceptor 52 at block 136 and determines whether the bill acceptor 52 is operational at block 138. If the bill acceptor is operating in the up state as determined at block 138, then at block 140 the CPU 64 determines whether the bill acceptor 52 has received a bill.

When the bill acceptor 52 receives a bill input through the slot 64, the bill acceptor 52 responds to polling from the CPU 64 with an in-use message. At this time, the bill acceptor 52 verifies the validity and type of the received bill and determines whether the bill is acceptable.

After determining the banknote acceptance device 52, the CPU 64
The banknote information is transmitted to the CPU 64 of the slot machine in response to polling by the slot machine. CPU64 at block 142
receives banknote information from the banknote accepting device 52. The banknote information includes either a "bill return" message when the banknote is invalid or of a type that cannot be accepted, or the types of banknotes held by the λ banknote accepting device 52 that can be accepted. .

If a valid bill is received by the bill acceptor 52 and the bill is not returned as determined by the CPU at block 144, the CPU 64 instructs the coin input device 118 at block 146 to transfer the coin to the slot machine. Make it impossible to enter 10. Coin input device 118
includes a device for detecting coin validity, which detects coins that are determined to be bad, and which also rejects coins when commanded to do so by CPU 64. The coin validity detection device passes the coin toward the coin hopper if the coin is determined to be valid and can be accepted. Downstream of the coin validity detection device is a switch that senses the presence of an incoming coin as the coin passes toward the coin hopper. CPU 64 updates the value in RAM 82 representing the current number of coins in coin hopper 26 in response to actuation of the switch. CPU 64 also determines whether a coin was accepted after issuing a lockout command to coin input device 118 at block 148 in response to actuation of the switch. If a coin is accepted after locking out, the CPU 64 executes "Banknote Rejection" in block 150.
Send the message to bill acceptor 52, block 132
to perform slot machine game routines. If no coins have been accepted after lockout, as determined at block 148, the CPU 64 checks the supervisory switch 108 and checks the bill acceptor 52 and the cash box 5 at block 152.
6 is in place and, at block 154, whether any doors are open. If the monitor switch 108 indicates that the bill acceptor 52 or cash box 56 has been removed or that the door is open, the CPU 64 sends a bill rejection method to the bill acceptor 52 at block 156.

If the monitor switch 108 indicates that the device is good, the CPU 64 sends a "Credit Start" message to the bill acceptor 52. (Block 158).

Bill acceptor 52 responds to the "Start Credit" message by accepting the received bill and passing the bill to cash box 56 . At block 160, the CPU 64 polls the bill acceptor 52 again for a sales message indicating that the bill has been delivered to the cash box 56. block 16
Upon receiving a sell message from the bill acceptor 52, as determined by the CPU 64 in block 1
At 64, the exchange value for the type of bill received is retrieved from the table stored in the EPROM 82, and the exchange value is stored in the payment counter register of the RAM 82. The exchange value represents the number of coins required to exchange received banknotes. After initializing the payout counter at block 164, CPU 64 enables the hopper motor at block 166 to cause homper 26 to eject coins through payout chute 24. As mentioned above, hopper 26 includes a switch that detects each coin dispensed from the hopper. CPU 64 monitors the hopper switch and determines whether it has been activated. As determined at block 168 (finally, when the hopper switch is actuated to indicate that coins have been disbursed from the hopper, CPU 64 updates RAM 82 and quantity indicator 48 at block 170. Then, the CPU 64 decrements the payment counter by 1 and increments the value (T (stored in AM 82) of the exchange coins to be paid and the total slot machine output (stored in AM 82). The memory location is incremented and the display displays the number of coins currently being paid.The CPU 64 resets the hopper switch at block 172 and determines whether the payout counter has reached zero at block 174. If it has not reached zero, CPU 64 waits for the hopper switch to be activated again and loads RAM 8 when the next coin is paid.
2 and the quantity display 48 are updated. When the payment counter reaches zero, as determined at block 174, the CPU 64
stops the hopper electric motor 4 at block 176, and blocks 12
Return to 2.

As described above, the banknote verification exchange device of the present invention can exchange a large number of different types of banknotes for the convenience of slot machine players. Players no longer need to leave the machine or wait for casino personnel when they need to exchange money. Furthermore, for the convenience of the player, only coins of the same type as those accepted by the slot machine are exchanged to play the game. The word coin used here is
It is meant to include substitute coins issued by casinos and representing amounts for which no real coins have been minted, i.e., which are not immediately available.
