Description

  The present invention relates to a monitoring system for medal game machines, and more particularly to a system that can monitor illegal games of game machines.

  In an amusement arcade where entertainment is provided by pachinko machines or pachislot machines, so-called hall computers (monitoring control system) are installed in the management room to monitor the operating status of each game machine in the hall. Normally, hall computers are given the number of appearances of events such as pachinko balls and medals for each game machine, and the number of events such as bonuses. By checking these, it is possible to estimate whether or not there was an illegal game. .

  However, since it is necessary to take data from a large number of game machines sequentially and perform statistical processing, and to estimate fraudulent games from the results, fraudulent games can only be known after the amusement park is closed and fraudulent games are performed. The fact was that it was not possible to detect it while it was. In particular, illegal games have become more sophisticated recently, and the control device inside the game machine has been modified by installing special equipment or electromagnetic operations to win large prizes regardless of the winning pattern, or to make it easier for the winning pattern to appear. Unauthorized play is difficult to detect immediately and damage tends to increase.

  On the other hand, in order to eliminate arbitrary operations on the hall side for winning a prize, it is not permitted to control the control device inside the game machine from the outside of the game machine, and equipment that can take in signals from the outside Since it is not authorized to be attached to a game machine, it is very difficult to automatically detect illegal games.

  On the other hand, a winning situation monitoring device has been proposed in which a winning pattern and a medal payout number are output from a pachislot machine to a hall computer, and it is determined that there has been an illegal game when the winning pattern does not match the medal payout number. (Patent Document 1).

  In addition, a sensor is provided in the medal dispenser in the pachislot machine to detect the passage of medals, and the number of one payout is counted, and when one medal payout number exceeds the set limit number, it is determined that the game is illegal. An unauthorized payout detection device has been proposed (Patent Document 2).

JP 2003-275371 A JP 2001-177882 A

  However, the winning status monitoring device described in Patent Document 1 does not consider medal credits (storage). For example, until 50 credits are awarded, medals are not paid out even if there is a win, and it is mistaken for illegal games. Comparing the winning pattern with the number of medals paid out for fraudulent acts that may be detected and use a device that disguises the insertion of medals and does not use credit medals or play medals. It cannot be dealt with alone.

  Further, in the illegal payout detection device described in Patent Document 2, an act of acquiring a number that does not exceed the set limit number of medals per time cannot be detected even if it is due to illegal play.

  In view of such a situation, an object of the present invention is to provide a medal game machine monitoring system capable of detecting illegal games in real time.

Therefore, the medal gaming machine monitoring device according to the present invention is a medal gaming machine monitoring system that detects illegal games of gaming in a gaming machine, and detects a medal inserted into the medal slot of the gaming machine. An insertion sensor that receives the signal from the insertion sensor, counts the actual number of sheets inserted, a payout sensor that detects a medal paid out from the hopper of the medal dispenser in the game machine, and a signal from the payout sensor. A payout counter that counts the actual payout number received, a signal of the number of used games output from the control device in the game machine to an external monitoring control system, and a game payout number output from the control device in the game machine to the medal payer signal, and inputs the count signal from the charged counter and payout counter, calculating the formula I or easier credit number below On the other hand, the error monitoring value calculated from the hopper idling time of the medal dispenser is calculated to calculate the average value of the error monitoring, and the setting value where the number of credits is within the setting range and the error monitoring value exceeds the average value A monitoring processing device that determines that it is normal when the number of credits is less than that, and determines that the game is fraudulent when the number of credits is out of the setting range or when the number of credits is within the setting range and the error monitoring value is greater than or equal to the set value exceeding the average value ; It is provided with.
The actual number of medals inserted-Number of used games + Number of game payouts-Actual payout number = Number of credits
(Formula I)

  When playing a pachislot machine, play 1 to 3 medals into the medal slot of the game machine, or use 1 to 3 medals in the credit and operate the lever to start the game. . When there is a win, the number of medals to be paid out is determined according to the winning pattern. When the credit is not full, the actual medal is not paid out until the credit is full. The number obtained by subtracting the number of credits is paid out from the medal dispenser to the tray.

  There is no prize for each game. In normal games, the difference between the number of throws and payouts increases on the throwing side, and if there is an event such as a big bonus or regular bonus, a large number of medals are paid out to the tray.

  One of the features of the present invention is that the actual number of sheets inserted is counted by an input sensor and an input counter, and the actual number of discharged sheets is counted by a payout sensor and a payout counter.

The pachislot hall computer checks the difference between the number of games used (number used for each game) and the number of game payouts (winning number). If it can be counted, the number of credits can be calculated from the following formula I.
The actual number of medals inserted-Number of used games + Number of game payouts-Actual payout number = Number of credits
(Formula I)

  The number of credits fluctuates within a range of 0 to 53 for each pachislot machine during the operation of the pachislot store, and is a value that becomes 0 when the business ends. In other words, at the end of business, the formula of the actual number of inserted medals-the actual number of paid-out coins = the number of used games-the number of game pay-outs is established. However, since the number of credits varies within the range of −53 to +53, it can be considered that there is no problem because the number of credits varies in the range of −53 to +53. Accordingly, it can be determined that the game is normal when the number of credits is within the range of −53 to +53, and that the game is fraudulent when the number of credits is outside the range of −53 to +53.

  For example, if a device that disguises the insertion of medals is used, the number of credits increases even though no medal is inserted into the medal slot, and there is no control signal for increasing the credit from the control device in the game machine. However, the value is outside the range of −53 to +53. Note that 53 sheets correspond to the number of creditable sheets of the current pachislot machine, and the range can be set by other numerical values.

  For example, if the payout sensor is short-circuited during the big bonus so that the medal cannot be detected and the hopper is continuously rotated to steal the medal, the calculated credit number is within the normal range. Unauthorized play cannot be detected.

  Usually, the payout time for one medal is about 0.1 seconds in the current pachislot machine. Therefore, if there is a hopper idle time between the last medal payout and the next medal payout, the idle time is detected and the number of medals issued during that time is calculated and the number of medals is monitored for error. The average value is obtained.

  In the case of illegal play as described above, since the error monitoring value greatly exceeds the average value, for example, 10 times or more, the number of credits is in the range of −53 to +53, but the error monitoring value is If the set value is much higher than the average value, it can be determined that the game is fraudulent.

  If each of the actual number of inserted medals and the actual number of paid-out medals is detected by two sensors, it is possible to detect an illegal payout of medals due to the idling of the hopper without using an error monitoring value.

  That is, two payout sensors for detecting medals paid out from the hopper of the medal dispenser in the game machine to the tray are provided at different locations, and the number of credits is counted within the set range and counted from the signals of the two payout sensors by the monitoring processor. When the number of paid out coins matches, it is judged as normal, and when the number of credits is out of the set range or when the number of credits is within the set range and the payout number counted from the two payout sensors does not match, it is judged as illegal play. It can also be configured.

  In this case, when the number of payouts counted from the signals of the two payout sensors does not match, an alarm is given by the pachislot machine or hall computer, and the difference between the payout numbers is displayed, so that the response can be made more smoothly.

  Further, according to the present invention, since a signal from the game machine is received and monitored and a control signal is not input to the equipment in the game machine, a monitoring system adapted to the regulations can be constructed.

  The above-described determination as to whether the game is illegal or normal may be performed for each game, or may be performed on a daily basis.

  The credit counter may count the credit display of the game machine, but since there is a credit command and a signal of the number of credits in the control device in the game machine, the signal can be taken out and used.

  As the insertion sensor and the payout sensor, a known optical sensor, magnetic sensor, or contact sensor that detects the contact of a medal can be used. The insertion sensor may be provided in the vicinity of the medal insertion slot in the game machine. The payout sensor may be arranged between the medal payer and the medal tray.

  The monitoring processing device may be realized by a hall computer, or a dedicated computer may be provided to realize the function.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 and 2 show a preferred embodiment of a medal game machine monitoring system according to the present invention. In the figure, the medal game machine 10 is provided with a door 12 on the front surface of a housing 11 so that the door 12 can be opened and closed. A window 13 is formed on the door 12 so that the design of the reel 14 can be seen from the window 13. .

  Further, the door 12 is provided with a start lever 15, a medal insertion port 16, and a medal payout port 17, a medal hopper 18 is disposed in the housing 11, and a medal transport path 19 is disposed in the medal insertion port 16. The medal hopper 18 is provided so as to extend, and a medal payer 20 is provided below the medal hopper 18. The medal payout port 17 is formed with a medal payout port 17. Oriented. In addition, since the structure of the medal game machine 10 is the same as a conventionally well-known thing, the detailed description is abbreviate | omitted.

  The medal transport path 19 is provided with an insertion sensor 31 that detects insertion of a medal, and the medal payout port 21 is provided with a payout sensor 32 that detects the payout of medals. The sensors 31 and 32 are, for example, an optical sensor and a magnetic sensor. Or it comprises a contact sensor.

  In the medal game machine 10, a main board equipped with one or a plurality of CPUs for controlling the operation of the reel 11, events such as winnings and bonuses, the number of coins inserted, credits, the number of payouts corresponding to the winning pattern, etc. A control device 22 composed of a sub-board is mounted.

  The signals of the insertion sensor 31 and the payout sensor 32, various control signals and data of the control device 23 are input to the hall computer 40, and the hall computer 40 receives the various control signals and data of the control device 22 and the operation status of the medal game machine 10 To monitor.

The hall computer 40 receives signals from the insertion sensor 31 and the payout sensor 32 by the function means 41 and 42 of the insertion counter and the payout counter, and counts the actual number of coins inserted and the actual number of coins paid out. Receiving signals and data,
The number of credits is calculated using the formula: actual number of medals inserted-number of used games + number of game payouts-actual payout number = credit number.

Further, the control device 22 of the pachi-slot machine 10 determines whether the idle time of the medal hopper 18 is idle between the last medal payout and the next medal payout, for example, from the rotation operation of the drive motor of the medal hopper 18 or the sensor. Is detected, and the number of sheets in between is calculated, and the number is output to the hall computer 40 as an error monitoring value. The hall computer 40 obtains an average error monitoring value, and the number of credits is within the set range. and error value of the monitoring is determined to be normal when less than the set value greater than the average value, the set value the value of time or number of credits is set range a and error monitoring outside the range credit number exceeds the average value At the above time, it is determined that the game is illegal.

  When playing a pachislot machine, if 1 to 3 medals are inserted into the medal slot of the gaming machine 10 or 1 to 3 medals in the credit are inserted and the lever 15 is operated, the drum 14 rotates and the game is started, and the drum 14 is stopped by pressing three stop buttons. If there is a winning, the picture corresponding to the winning pattern is stopped on the drum 14, and at the same time, the number of medals to be paid out corresponding to the winning pattern is determined. When the number of credits is not full, first, When the game is full without being paid out, the number used in the game is credited, and the number obtained by subtracting the credited number from the number corresponding to the winning pattern is paid out from the medal dispenser 20 to the medal tray 21.

  At that time, insertion of medals into the medal insertion slot 16 is detected by the insertion sensor 31, and payout of medals from the medal dispenser 20 is detected by the payout sensor 32. Signals from these sensors 31 and 32 are input to the hall computer 40.

  Further, the control device 22 in the pachislot machine 10 has signals such as the number of credits, a credit command, the number of credits, a command to insert a medal using credits, and the number of credits to be subtracted from the number of credits. Input to the hall computer 40.

  In the hall computer 40, the insertion counter function means 41 receives the signal from the insertion sensor 31 and calculates the actual number of medals, and the payout counter function means 42 receives the signal from the payout sensor 32 and calculates the actual number of medals. Then, the calculation result is given to the monitoring processor 43.

  A signal related to credit is input to the monitoring processing device 43 from the control device 22 of the pachi-slot machine 10, and the monitoring processing device 43 receives the actual number of inserted medals, the actual number of paid-out medals, and the number of medals used in the game ( The number of credits is calculated from the number of used games) and the number of winning prizes (number of paid out games).

  Further, in the control device 22 in the pachislot machine 10, when the medal hopper 18 is idle between the last medal payout and the next medal payout, the idling time is detected, for example, calculation of idling time / 0.1. The number of sheets in the meantime is calculated using an equation, and the number of sheets is set as an error monitoring value, which is input to the hall computer 40, and the average value is obtained and stored.

  When the number of credits is in the range of −53 to +53 and the error monitoring value is less than 10 times the average value, the monitoring processing device 43 determines that it is normal and does not activate the alarm 44.

  For example, when a medal-inserted camouflage device is used and 10 games are played with credits raised to 50 (however, no winnings will be given), actual input 0-game use number 30 + game result payout number 0-actual The number of payouts becomes 0 = −30 and suddenly becomes −30, which is within the range of −53 to +53. However, if the illegal game is further continued, the number of credits of − gradually increases and exceeds −53, so it can be determined that the game is an illegal act, and the monitoring processor 43 activates the alarm 44. The hall manager can quickly deal with illegal play.

  In this case, when the number of credits exceeds the range of −53 to +53, an illegal play alarm may be issued immediately. However, after the number of credits exceeds the range of −53 to +53, the number of credits of − is increased. When the game to be continued is further continued, it may be determined that the game is illegal.

  In addition, when the medal hopper 18 is continuously rotated by short-circuiting the power supply box or the like, and the medals are stolen, the actual insertion number, the number of used games, and the number of game payouts do not change even in this case. Since the number of credits increases rapidly and exceeds −53, it can be determined that the game is fraudulent, and the monitoring processor 43 activates the alarm 44.

  Furthermore, in the case of an illegal game in which the counting of the payout sensor 32 is stopped, when a prize is awarded with the credit set to 50, the payout of medals is started. Release the short circuit just before the alarm occurs. For example, if there are 10 winnings, the first 2 shots are shorted, and if the medal hopper 18 continues to rotate, about 30 shots are paid out in 2 to 3 seconds. The payout sensor 32 counts normally, and the remaining 8 sheets are paid out. If this technique is executed many times, for example, during a big bonus, a large number of medals are illegally stolen.

  In the case of this illegal game, the number of credits is in the range of −53 to +53, so it cannot be determined as an illegal game. However, in the case of the system of this example, since the error monitoring value and the average value thereof are calculated, when the above-described illegal play is performed, the value of the monitoring error is calculated from the idling time, and the value of the monitoring error is calculated. Since the value far exceeds the average value, also in this case, the monitoring processor 43 determines that the game is illegal and activates the alarm 44.

  Further, after the end of business, even if the number of credits is −53 to +53, and the number of days when the error monitoring value is greater than or equal to the average value continues for many days, the number of credits is −53. Since it is ˜ + 53, it can be determined that the sensors 31 and 32 are normal, and an abnormality or failure of the medal hopper 18 is suspected. Therefore, when the medal hopper 18 is replaced and the error monitoring value returns to a value less than a value that greatly exceeds the average value, it can be finally determined that the medal hopper 18 is abnormal or malfunctioned.

  In addition, if it is confirmed that there is no illegal play, but the number of credits is continuously out of the range of −53 to +53, there is a possibility that the sensors 23 and 32 are not properly mounted or broken. Check the mounting state of the sensors 31 and 32. If the number of credits is still outside the range of -53 to +53, replace the sensors 31 and 32.

  In the above example, one insertion sensor 31 and one payout sensor 32 are employed. However, if two input sensors and two payout sensors are employed, it is difficult to short-circuit the two payout sensors at the same time. In the case of fraudulent games exploiting idling, there is a difference in the number of medal payouts counted from the signals of the two payout sensors, so it can be immediately determined that the game is fraudulent, and the set value based on the error monitoring value and the average value There is no need to compare with.

  That is, two payout sensors 32, 32 for detecting medals paid out from the hopper 18 of the medal payer in the game machine to the tray are provided at different locations, and the credit amount is within a set range by the control device (monitoring processing device) 22. When the number of payouts counted from the signals of the two payout sensors 32 and 32 matches, it is determined to be normal, and when the number of credits is out of the set range or the number of credits is within the set range and from the two payout sensors 32 and 32 When the counted number of payouts does not match, it can be configured to determine that the game is fraudulent.

It is a partial cutaway schematic diagram showing a pachislot machine provided with a surveillance system concerning the present invention. It is a figure which shows the system configuration example in the said embodiment.
