Description

  The present invention relates to an unauthorized state detection method, an unauthorized state detection device, and an unauthorized state detection counter for preventing an unauthorized act in a gaming machine such as a slot machine.

  In recent years, there are many cases in which a slot machine is illegally operated (got action) and malfunctioned, and the number of medal credits is illegally increased to illegally fraudulently deceive the medal.

  Various techniques for preventing such illegal acts have already been proposed. For example, Patent Document 1 proposes to provide a medal sorting device (medal selector) that determines the suitability of inserted medals. This medal sorting device recognizes that medals are properly inserted when medals are detected in order from the side closer to the medal entrance to the side farther from the medal entrance.

  However, a fraudulent act that inserts a fraudulent tool equipped with a light emitting element from the medal insertion slot and falsely creates a medal insertion state by erroneously operating the medal detection unit by the optical sensor and illegally increases the number of credits. Cannot be dealt with by the method described in Patent Document 1.

Therefore, Patent Document 2 proposes a fraud prevention method that detects fraud when the number of credits increases when the start lever is operated and the medal reception is prohibited.
JP 2001-155223 A JP 2005-304623 A

  According to the fraud prevention method disclosed in Patent Document 2, fraud is detected by looking at the number of credits, but the number of credits that are grasped by a hall computer that centrally manages a number of slot machines at each amusement store Does not count the number of medals that are actually credited (internally held), so there is a risk that fraudulent acts cannot be reliably detected. That is, the hall computer generally receives start information indicating that the start lever of each slot machine has been operated and payout information indicating how many medals have been paid out by each slot machine, and receives the medal of each slot machine. Since the difference between input and payout is managed, it is impossible to know whether or not the grasped credit number is correct. For this reason, it has been very difficult to reliably detect fraudulent acts such as Clemence in real time.

  Accordingly, an object of the present invention is to provide a gaming machine fraud state detection method, a fraud state detection device, and a fraud state detection counter capable of reliably detecting a fraudulent act in real time.

  If the credit number Cr calculated in this manner is outside the predetermined range, it is more preferable to determine that the gaming machine is in an unauthorized state.

  An input reference signal or a payout reference signal determined by actually inserting a game medal is experimentally stored in advance, and the stored input reference signal or the payout reference signal is detected. It is also preferable to include determining that the detection signal actually detected by comparing with the actually detected detection signal is due to insertion or payout of the game medal. In this case, the detection signal actually detected by comparing the duration of the stored input reference signal or payout reference signal with the duration of the actually detected detection signal is determined to be the input or payout. It is more preferable to include a determination that the medals are inserted or paid out.

  It is also preferable that detection of actual insertion or withdrawal is detected by a clamp current sensor that detects a current flowing through a sensor that detects passage of a medal in a non-contact manner.

  FIG. 1 is a diagram showing a schematic configuration of a slot machine system in each game store as an embodiment of the unauthorized state detection device of the present invention. However, in the figure, only one slot machine is shown for the sake of simplicity, but in reality, a large number of slot machines are provided and are electrically connected to the hall computer. Yes.

  In the figure, 10 is a hall computer that centrally manages a number of slot machines, 11 is a slot machine, and 12 is a back door of the slot machine 11 that is shown in an open state. The slot machine 11 employs a credit system that allows a game to be executed using a deposit medal that has been inserted into the machine body in advance.

  A medal selector (medal selector) 13 is attached to the back door 12. The medal selector 13 is for selecting the suitability of game medals inserted through a medal insertion slot (not shown), and the selected regular medals are sent to the hopper 14. The medals and foreign matters removed by the medal selector 13 are sent to the medal discharge port 15.

  The medal selector 13 is provided with a medal passage sensor (not shown) that optically detects the passage of medals and outputs a detection current. In the present embodiment, the clamp type current sensor 16 that detects the detected current in a non-contact manner by clamping the signal line from the medal passage sensor (detects the current from a change in the magnetic field generated by the detected current) is the medal selector. It is installed at 13 portions or in the vicinity thereof.

  The hopper 14 accommodates a large number of medals, and the medal dispenser provided with the hopper 14 has a combination of child roles (wins) or a case where the number of credits exceeds a predetermined number (for example, 50). Then, the medal is sent out to the medal discharge port 15. Inside the medal dispenser, a medal passage sensor (not shown) that optically detects the passage of the medal and outputs a detection current is provided. In the present embodiment, the clamp-type current sensor 17 that detects the detected current in a non-contact manner by clamping the signal line from the medal passage sensor (detects the current from the change in the magnetic field generated by the detected current) pays out the medal. It is installed at or near the vessel.

  The output terminals of the clamp type current sensors 16 and 17 are electrically connected to the counting unit 20 by signal lines 18 and 19, and are configured such that detection signals from these sensors are sent to the counting unit 20. Data representing the actual inserted number of medals and data representing the actual paid-out number of medals, which are outputs of the counting unit 20, are configured to be sent to the hall computer 10 via signal lines 22 and 23.

  The power source of the counting unit 20 is obtained by converting commercial AC100V into DC5V by the AC / DC converter 21.

  In addition, the slot machine 11 includes a front door, three reels with a plurality of symbols displayed on the peripheral surface, a display window provided on the front door to make the reel symbol visible, a start lever, The number-of-deposits indicator that displays the number of medals deposited to the medals, the medal insertion switch that designates that the medals are consumed and the game is executed, the three stop button switches for individually stopping each reel, and the medal outlet 15 is provided with a medal tray, a speaker that outputs an alarm sound when fraud is determined, a control circuit board that controls the operation of the entire machine, and the like. Is omitted.

  FIG. 2 is a block diagram showing a schematic configuration of the counting unit 20 shown in FIG.

  The counting unit 20 detects only the actual insertion of medals and counts the actual number of medals, and detects only the actual payment of medals and counts the actual payout number of medals. It is configured. Specifically, as shown in the figure, from the output of the edge detection circuit 200a and the edge detection circuit 200a such as a comparator for detecting the fall and rise of the detection signal from the clamp type current sensor 16 relating to the medal insertion. Time calculation circuit 201a that calculates time between falling edges and rising edges or between falling edges, and edge detection such as a comparator that detects falling and rising edges of detection signals from clamp-type current sensor 17 related to medal payout A circuit 200b, a time calculation circuit 201b for calculating a time between falling edges and rising edges or between falling edges from the output of the edge detection circuit 200b, and a microcomputer 202 are provided.

  FIG. 3 is a flowchart showing the processing contents of the microcomputer 202 in the counting unit 20.

  Since the detection signals from the clamp type current sensors 16 and 17 are very weak, it is determined whether the signal is a noise signal, a false signal given in a pseudo manner, or due to actual insertion and withdrawal of medals. It is very important to do. For this reason, in this embodiment, the detection signals from the clamp-type current sensors 16 and 17 in the medal insertion and withdrawal are measured on a trial basis, and the medal is actually based on the insertion reference signal and the payout reference signal determined by the measurement. It is determined whether or not it has been inserted and paid out, and the number of medals is counted only when the insertion and withdrawal are actually performed. Since the medal insertion number counting process and the medal payout number counting process are basically the same, only the medal insertion number counting will be described below.

  Each time it is recognized that a medal has been inserted, the processing of FIG. 3 is executed. First, it is determined whether or not it is a test mode in which a medal is inserted on a trial basis and an insertion reference signal is created (step S1). In the case of YES, that is, in the test mode, it is determined whether this slot machine 11 is a type that generates one pulse by inserting one medal or a type that generates two pulses (step S2). .

  As shown in FIG. 4, the detection signal from the clamp-type current sensor 16 is a rectangular wave pulse that rises when the medal passes and rises when it passes. Depending on the type of slot machine, as shown in FIG. 4A, a type that generates one pulse for the passage of one medal (a type in which the current changes from high level → low level → high level), As shown in FIG. 4B, there is a type (a type in which the current changes from high level → low level → high level → low level → high level) that generates two pulses for the passage of one medal. In step S2, this type (signal type) is confirmed.

  In the case of YES, that is, as shown in FIG. 4A, the time calculation circuit 201a is the time between the falling edge and the rising edge obtained from the edge detection circuit 200a (low level). Is set to be calculated (step S3). On the other hand, in the case of NO, that is, as shown in FIG. 4B, when the type is to generate two pulses, the time calculation circuit 201a is between the falling edge obtained from the edge detection circuit 200a and the next falling edge. Is set so as to calculate the time (duration of low level and high level) (step S4).

Next, two medals are actually inserted from the medal slot. First, to store the time when the charged first sheet of medals as T ₁ (step S5). Then stores the time when the charged second sheet of medals as T ₂ (step S6).

Next, it is determined whether or not 0.3T ₁ <T ₂ <1.8T ₁ (step S7). If YES in step S7, that is, if 0.3T ₁ <T ₂ <1.8T ₁ , this T ₂ is stored as the input reference signal T _TH (step S8). If NO in step S7, it is determined that the test has failed (step S9), the process returns to step S1, and the test mode is repeated again.

If NO in step S1, that is, if it is not in the test mode, it is determined whether or not 0.3T _TH <T <1.8T _TH for the time T measured by inserting medals (step S10). If YES, that is, if 0.3T _TH <T <1.8T _TH, it is determined that one medal has actually been inserted, and the actual inserted number Cn is counted up by one (step S11). The process of FIG. 3 is terminated.

  If NO in step S10, the illegally inserted number E is counted up without counting up the actual inserted number Cn (step S12). Next, the illegally inserted number E is outputted to the hall computer 10 (step S13), and further, the fraud detection signal is outputted to a predetermined terminal of the hall computer 10 or the like, that is, the fraud detection signal is outputted to a device having an illegal display function ( For example, a call lamp or the like is output and displayed (step S14), and the processing of FIG. 3 is terminated.

  As described above, the counting process of the medal payout number by the counting unit 20 is basically the same as the processing content of FIG.

  The hall computer 10 is mainly composed of a microcomputer, and includes a medal insertion signal received from each slot machine, start information indicating that the start lever has been operated, a stop signal indicating that the reel has been stopped, a reel stop signal, In addition to the payout information, in this embodiment, various controls are performed based on the information on the actual inserted number Cn and the information on the actual payout number Hp received from the counting unit 20.

  FIG. 5 is a flowchart showing the processing contents of the portion of the hall computer 10 related to the present invention.

  In the slot machine 11, a game is usually started when a player inserts three or more medals and operates a start lever. First, when the hall computer 10 receives start information indicating that the start lever has been operated (step S50), the hall computer 10 recognizes that three medals have been inserted into the slot machine or bet from a credit, and the number of start information St is stored as St = 3 (step S51).

  Further, when the child roles are all paid out, the payout information is received and the payout information number Ot is stored (step S52).

  Next, the hole computer difference number HPC, which is the difference between the start information number St and the payout information number Ot, is calculated from HPC = St−Ot and stored (step S53).

  Further, the information on the actual input number Cn and the information on the actual payout number Hp are received from the counting unit 20 and stored (step S54).

  Next, the real counter difference number RC is calculated from RC = Cn−Hp and stored (step S55).

  Next, it is determined whether or not the medal passage sensor in the hopper has stopped operating for some reason during counting (step S56).

  If NO, that is, if the operation has not been stopped, the number of credits Cr is calculated from Cr = Cr ′ + Cn−St + Ot−Hp and stored (step S57). Here, Cr ′ is the previous credit number.

  If YES in step S56, that is, if the operation is stopped during counting, the number of credits Cr is calculated from Cr = Cr ′ + Cn−St + Ot−Hp + Hp2 and stored (step S58). However, Hp2 is a predicted value of the number of payouts to be described later.

  Thereafter, it is determined whether or not the calculated credit number Cr is within a predetermined range (step S59). The minimum number of credits Cr is 0. The maximum number of credits is 53, which is 50 sheets to be paid out and 3 of one inserted number. Therefore, in step S59, it is determined whether or not 0 ≦ Cr ≦ 53.

  In the case of YES, that is, in the case of 0 ≦ Cr ≦ 53, it is normal and the processing of FIG. If NO, that is, if Cr <0 or 53 <Cr, the fraud detection signal is output and displayed on a device having a fraud display function (for example, a call lamp) (step S60), and the processing of FIG. finish.

  FIG. 6 is a flowchart showing the processing contents executed by the counting unit 20 when the counting operation of the medal passage sensor in the hopper is stopped.

  When the counting operation stops, it is predicted how many sheets have been paid out during the time when the operation was stopped (step S60). Specifically, since it is known how many medals are paid out per second, the payout medal number Hp2 is predicted from the time during which the counting operation is stopped.

  Next, the predicted payout medal number Hp2 is output to the hall computer 10 (step S61), and the process of FIG. 6 is terminated.

  FIG. 7 is a flowchart showing the processing contents executed by the hall computer 10 when the settlement is performed.

  First, it is determined whether or not the settlement button has been pressed (step S70).

  In the case of YES, that is, when it is determined that the button is pressed, (total of start information number St) − (total of payout information number Ot) = (total of actual input number Cn) − (total of actual payout number Hp). Is determined (step S71). In the case of NO, that is, when not pressed, the processing of FIG. 7 is terminated as it is.

  If YES in step S71, that is, (total of start information number St) − (total of payout information number Ot) = (total of actual input number Cn) − (total of actual payout number Hp), it is normal. Therefore, the processing in FIG. 7 is terminated as it is. In the case of NO, that is, when (total of start information number St) − (total of payout information number Ot) is not equal to (total of actual input number Cn) − (total of actual payout number Hp), a fraud detection signal is generated. The information is output and displayed on a device having an unauthorized display function (for example, a call lamp) (step S72), and the processing of FIG. 7 is terminated.

  Hereinafter, with reference to Table 1, with respect to the actual game, the difference HPC, the credit number Cr, the actual inserted number Cn information, the actual paid number Hp information, The real counter difference number RC grasped by the hall computer based on the credit number Cr will be described. However, the description based on Table 1 is an operation description in the case where an illegal act is not performed.

  (Game 1) When, for example, 20 medals are inserted by the player and the game is started by operating the start lever, on the slot machine 11 side, 3 cards are used as a bet in the game, and the rest Are added to the number of credits. Here, since start information is sent to the hall computer 10, the hall computer difference number HPC is HPC = St−Ot = 3, but the actual input number Cn information and the actual payout number Hp information from the counting unit 20. Therefore, the real counter difference number RC grasped by the hall computer 10 based on these pieces of information is RC = Cn−Hp = 20−0 = 20. The credit number Cr is given by Cr = Cr ′ + Cn−St + Ot−Hp. In this case, Cr = 0 + 20−3 + 0−0 = 17. As a result of this game 1, if there are 10 child payouts, the hole computer difference HPC is HPC = −10, but these 10 cards are not actually paid out and become credits. The payout number Hp = 0, and therefore the real counter difference number RC is RC = 0-0 = 0. In this case, the credit number Cr is Cr = 17 + 0-0 + 10-0 = 27.

  (Game 2) When the player presses the bet button for the next game, three credits are consumed and the game is ready. If the start lever is operated in this state, start information is sent to the hall computer 10, so the HPC difference number HPC is HPC = St−Ot = 3. However, since a medal is not actually inserted, The inserted number Cn = 0, and therefore the real counter difference number RC is RC = 0. The credit number Cr is Cr = 27 + 0−3 + 0−0 = 24.

  (Game 3) Furthermore, if 10 medals are inserted, the game is operated by operating the start lever, and there are 15 child payouts, start information and 15 payout information numbers are sent to the hall computer 10. The hole computer difference number HPC is HPC = St−Ot = 3−15 = −12. On the other hand, since 10 medals are actually inserted, the actual inserted number Cn = 10. However, 15 sheets are not actually paid out and become credits, so the actual paid-out number Hp = 0, and therefore real. The counter difference number RC is RC = 10. The credit number Cr is Cr = 24 + 10−3 + 15−0 = 46.

  (Game 4) Next, when the bet button is pressed, 3 credits are consumed from the credit number Cr, and a game is possible. In this state, if the game is operated by operating the start lever, and the 15 child payout child roles are gathered, the start information and the payout information of 15 payouts are sent to the hall computer 10, so the hall computer difference HPC is HPC = St -Ot = 3-15 = -12. On the other hand, since the number of credits Cr exceeds 50, ie, Cr = 46 + 0-3 + 15-0 = 58, eight are paid out, so the actual payout number Hp = 8, and therefore the real counter difference number RC is RC = Cn−Hp = −8. Further, the credit number Cr is Cr = 50.

  (Game 27) When the player finishes the game 27 and presses the checkout button, the credit Cr becomes 0 and the remaining one is paid out. In this case, although the hole computer difference number HPC is HPC = 0, since medals are actually paid out, Hp = 1 and the real counter difference number RC becomes RC = Cn−Hp = −1. Further, as described above, it is determined whether or not (total of start information number St) − (total of payout information number Ot) = (total of actual input number Cn) − (total of actual payout number Hp). However, in this case, 81−40 = 50−9, and the two are equal, so that the illegal act is not performed.

  As described above, the hall computer difference number HPC is obtained from the start information and the payout information sent from the slot machine 11 by calculating the start information number St−the payout information number Ot. Since the difference number is usually the number of inserted medals-the number of paid-out medals, it is a measure of sales at a management store. In the case of Table 1, the store has acquired 41 cards. If this value is negative, the player has acquired it. In the prior art, the hole computer side only unilaterally calculates the difference number HPC from only the start information and the payout information, and it could not be confirmed whether this is the correct difference number. Since the real counter difference number RC is calculated from the number Cn and the actual payout number Hp, it is possible to determine whether or not an illegal act has been performed by comparing the two. In other words, if (total of start information number St) − (total of payout information number Ot) = (total of actual input number Cn) − (total of actual payout number Hp) at the time of liquidation, an illegal act is performed. It can be identified that it is normal.

  Also, according to the prior art, since the number of medals actually inserted is unknown, the correct number of credits Cr cannot be calculated. That is, the number of credits Cr cannot be calculated without knowing the actual inserted number and the number of credits paid out exceeding 50. However, in the present embodiment, since the actual insertion number Cn and the actual payout number Hp are known, the credit number Cr can be obtained from Cr = Cr ′ + Cn−St + Ot−Hp or Cr = Cr ′ + Cn−St + Ot−Hp + Hp2. . Then, by knowing the number of credits Cr, it is possible to grasp whether an illegal act has been performed.

  As one of the fraudulent acts, there is one that uses a device called Clement and causes a medal selector to malfunction continuously to create a pseudo medal insertion state. In response to such an illegal act, the counting unit 20 according to the present embodiment determines that no medal has been actually inserted and does not count up the actual inserted number Cn. Since the fraud detection signal is output to a predetermined terminal of the hall computer 10 or output to a device having a fraud display function (for example, a call lamp or the like) and displayed, the fraud detection occurs. Is grasped. Of course, depending on whether or not the number of credits Cr is 0 ≦ Cr ≦ 53, and also by comparing the hall computer difference number HPC and the real counter difference number RC at the time of liquidation, an illegal act by Clement is performed. It is possible to know whether or not

  There is what is called a hopper goto that illegally pays out medals as another illegal act. In response to such an illegal act, the counting unit 20 of the present embodiment counts up the number Hp of medals actually paid out, so that the correct payout number can be grasped, so the credit number Cr is 0 ≦ Cr. Depending on whether or not ≦ 53, it is possible to grasp whether or not a fraudulent act of hopping has been performed by comparing the hall computer difference number HPC and the real counter difference number RC at the time of liquidation.

  As described above, when the counting operation of the medal passing sensor in the medal dispenser is stopped by some improper method, it is predicted how many sheets have been paid out during the time when the operation was stopped, The predicted number of payout medals Hp2 is output to the hall computer 10 and a fraud detection signal is output to a predetermined terminal of the hall computer 10 or output to a device having an illegal display function (for example, a call lamp).

  Next, the operation of the unauthorized state detection device in the present embodiment when it is assumed that an unauthorized act has actually been performed will be described.

  Table 2 shows a simulation of a case where a fraudulent act of creating 50 pseudo medal insertion states using Clement and making a liquidation without playing a game is performed.

  When 50 pseudo medals are inserted by Clement, the slot machine 11 side erroneously grasps that the number of credits (slot machine credits) is 50. However, since medals are not actually inserted, the actual inserted number Cn is Cn = 0, while the actual payout number Hp counts the number actually paid out. Therefore, when the actual payout number Hp = 50, the credit number Cr becomes Cr = −50, and it is immediately detected that an illegal act has occurred. Furthermore, since the hall computer difference number HPC and the real counter difference number RC do not coincide with each other at the time of liquidation, it is detected that an illegal act has occurred.

  Table 3 shows a simulation of a case where an illegal act of playing a game by creating 50 or 20 pseudo medal insertion states using Clement.

  When 50 pseudo medals are inserted by Clement, the slot machine 11 side erroneously grasps that the number of credits (slot machine credits) is 50. However, since medals are not actually inserted, the actual inserted number Cn = 0 and the actual payout number Hp = 0. For this reason, since the number of credits Cr becomes Cr = -3, it is immediately detected that an illegal act has occurred. Furthermore, since the hall computer difference number HPC and the real counter difference number RC do not coincide with each other at the time of liquidation, it is detected that an illegal act has occurred.

  Table 4 is a simulation of a case where a fraudulent act called a hopper goto is performed during a normal game. In this fraudulent act, the credit of the slot machine is always maintained at 50, and when a child role with a payout is collected, more medals than the prescribed payout number are exploited from the hopper.

  The hopper counts the number of medals paid out, and is configured to stop the payout operation when the counted number reaches a specified number based on a payout signal sent from the slot machine. The person who performs the fraudulent action forcibly stops the operation of the medal passage sensor of the hopper at the moment when the payout starts, for example, when the first two pieces are paid out in the case of payout of 10 pieces. Since the sensor counts only 2 sheets, it continues to pay out 10 sheets. The medal passage sensor is configured to detect an abnormality by itself and recognize an error when the operation is stopped for 3 to 5 seconds. For this reason, if the operation is resumed immediately before recognizing the error, it is mistakenly recognized that the payout has not been made, and the remaining 8 medals are paid out. However, according to the present embodiment, it is predicted how many payouts have occurred during the time when the counting operation of the medal passing sensor in the medal payer is stopped, and using the predicted payout medal number Hp2, the credit number Cr is calculated. Since Cr = Cr ′ + Cn−St + Ot−Hp + Hp2 and Cr = 69, it is immediately detected that an illegal act has occurred. Furthermore, since the hall computer difference number HPC and the real counter difference number RC do not coincide with each other at the time of liquidation, it is detected that an illegal act has occurred.

  Table 5 is a simulation of a case where a fraudulent act called “hopper god” is performed during a big hit (BIG) game. In this fraudulent action, when the credit of the slot machine is 50 due to the jackpot and the payout from the hopper continues until the end of the jackpot, each time the payout is made, a medal that greatly exceeds the prescribed payout number is exploited.

  If you win a jackpot, the slot machine credit will be 50 in several games, and payout will continue until the end of the jackpot, but each time you pay out, the operation of the hopper medal passing sensor will be forcibly stopped as in Table 4 In this way, a large amount of medals are paid out. However, according to the present embodiment, it is predicted how many payouts have occurred during the time when the counting operation of the medal passing sensor in the medal payer is stopped, and using the predicted payout medal number Hp2, the credit number Cr is calculated. Since it is obtained from Cr = Cr ′ + Cn−St + Ot−Hp + Hp2 and Cr = 59, it is immediately detected that an illegal act has occurred. Furthermore, since the hall computer difference number HPC and the real counter difference number RC do not coincide with each other at the time of liquidation, it is detected that an illegal act has occurred.

  Table 6 shows a simulation of a case where a fraudulent act called hopper goto, which is a forced hopper payout, is performed. In this fraudulent act, a portion that controls payout (rotation) of the hopper is operated from the outside, so that the hopper is forced to malfunction and a large amount of medals are exploited.

  When a large amount of medals are paid out by such a forced operation of the hopper, according to the present embodiment, since the number of credits Cr becomes Cr = −1975, it is immediately detected that an illegal act has occurred. Furthermore, since the hall computer difference number HPC and the real counter difference number RC do not coincide with each other at the time of liquidation, it is detected that an illegal act has occurred.

  All the embodiments described above are illustrative of the present invention and are not intended to be limiting, and the present invention can be implemented in other various modifications and changes. Therefore, the scope of the present invention is defined only by the claims and their equivalents.
