Abstract

PROBLEM TO BE SOLVED: To provide a fraudulent game detection device capable of increasing the accuracy of detecting a ball for each player.
A management device obtains a ball in each pachinko gaming machine 1 based on a signal from a pachinko gaming machine 1 and a sales signal from a ballroom lending machine, and detects an illegal holding ball with the ball. Then, the voice management device 7 notifies the income 8 carried by the employee. In this case, if sales occur with a lot of balls, if the customer moves the table with the ball and the next player plays, or if the ball is full Therefore, if it is output to the income 8 so as to confirm whether the customer change or the game is continued, and the employee instructs the customer change with the remote control device 10, the sales are in a state where there are a lot of balls. If the reserve ball after the occurrence is used as a ball, and the game is instructed to continue, the reserve ball is added to the ball. Thereby, since the precision of a holding ball can be raised, the precision of fraud detection can be raised.

Description

  The present invention relates to a fraudulent game detection device that detects fraud based on a ball for each gaming machine.

As a method for detecting fraud by a player, in the method of Patent Document 1, a difference ball is initialized every time sales occur, and when the difference ball exceeds a predetermined value (sales amount), fraud is performed. Judgment is made, or it is judged that fraud has been performed when the difference from the start of business becomes a predetermined value (sales) or more (see Patent Document 1).
In the former case, it is premised on the condition that sales are generated only in the state where there are no balls, and in the latter case, it is premised that the table movement is prohibited even with a small amount of balls.
Japanese Patent No. 2837481

  However, looking at the actual situation of game stores, there are many game stores that have purchased prepaid cards in advance and have introduced a card system for playing games using the value stored in the prepaid card. In this case, it is rare that a big hit is generated with the value of the prepaid card being used up and a large number of holdings are held, and usually a big hit is generated with the value remaining on the prepaid card.

By the way, in order to prevent fraud, the card system has many restrictions on the use of the prepaid card for the next time while leaving the value of the prepaid card, such as making the prepaid card usable only at the game store or giving an expiration date. As a customer's psychology, it tries to use it on the day of purchasing a prepaid card.
In addition, although there are amusement stores where prepaid card clearing machines are installed, it is troublesome to go to the clearing machines and clear them one by one. Furthermore, the exchange rate for exchanging game balls for prizes is close to equivalent exchange.

Due to this situation, some players may end up with the value left on the prepaid card even though they have a ball, and the difference ball is initialized every time sales occur. In this case, the reliability of data for fraud detection is lost, and fraud detection is also performed for an act permitted by the game store.
On the other hand, even a game shop that prohibits the movement of the ball is allowed to move the table if the amount of the ball is small, and the player moves the table without using up the ball. For this reason, since the relationship between the sales balls and the difference balls is broken, it is difficult to detect fraud by moving the holding balls.

As a result of the inaccuracy of the holding ball in this way, the count value of the game medium by the counter and the comparison of the holding ball are also inaccurate, the detection accuracy of the goto action is lowered, and the game shop suffers a disadvantage.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fraudulent game detection device capable of increasing the accuracy of detecting a ball for each gaming machine.

  The present invention is provided with a calculation means for calculating a ball for each gaming machine, provided with a customer change detection means for detecting a customer change based on the ball calculated by the calculation means at the timing when the sales of the game medium occurs, When this customer change detection means detects a customer change, an initialization means is provided for initializing the holding balls by the calculation means, and an unauthorized detection means for detecting fraud based on the holding balls calculated by the calculation means is provided. In addition, the customer change detection means performs a customer change when sales occur in a state where the holding ball calculated by the calculation means is less than a first set value which is a predetermined value based on one unit of lending. The fraud detection means detects fraud when the holding ball calculated by the calculation means falls below a predetermined fraud setting value that is less than one unit of gaming media lending by zero (claim). Item 1).

In the above configuration, the customer change detection means detects a customer change when the holding ball calculated by the calculation means becomes non-operating in a state less than a second set value which is a predetermined value equal to or less than zero. (Claim 2).
In addition, there is provided a customer replacement estimating means for estimating a customer change based on the possession ball calculated by the calculating means at the timing when the sales of the game medium occurs, and when the customer replacement estimating means estimates a customer change, When the customer replacement input means inputs the customer change, the initialization means initializes the holding ball by the calculation means, The customer replacement estimation unit may estimate the customer replacement when sales occur in a state where the holding ball calculated by the calculation unit is equal to or higher than a third set value higher than the first set value ( Claim 3).

In addition, the calculating means temporarily sets a holding ball after the customer change estimating means estimates a customer change, and the customer change input means inputs the customer change until a predetermined period elapses. If not, the spare holding ball is added to the holding ball, and if the customer change input means inputs a customer change, the spare holding ball may be used as a holding ball (claim 4).
Moreover, when the said calculating means adds a spare holding ball to a holding ball, the said customer change estimation means may not make it guess a customer change until a gaming machine becomes non-operation (Claim 5).

If a player moves a table with a small amount of balls (for example, 100 balls in the case of a pachinko machine) and the next player receives a rental of game media to play, the amount of balls is small. Sales occur in the state of.
Therefore, according to the first aspect of the present invention, the customer change detection means detects the customer change and initializes the possession balls when the sales are generated with a small amount of possession balls. Therefore, if a player moves a table with a small amount of balls and the next player receives a game media loan to play, the number of balls will be zero and match the actual number of balls. .

However, since it is normal for a player to buy additional game media due to a decrease in the number of balls, the customer replacement detection means is a uniform customer replacement when sales occur with a small number of balls. When the ball is initialized and the ball is initialized, the ball at the time when the sales are generated becomes an error, and when the player uses up the ball, the ball has a value of zero or less (for example, −100 balls). .
However, the fraud detection means detects fraud when the possession ball is less than a first set value (for example, -125 balls), which is a predetermined value based on one unit of gaming media lending. Ball errors do not cause fraud detection noise.

On the other hand, if a player moves a table with a small amount of balls and the next player purchases game media continuously to play, sales are generated each time the game media is rented out as a unit of lending. However, it is necessary not to initialize the holding ball under such conditions. In this case, when a player purchases game media continuously, it is normal to purchase while using the game media, so the first set value is a value slightly less than one unit of game media lending. It is desirable to use 100 balls when 1 unit of lending is 125 balls.
As described above, as a result of the holding ball being accurate, the accuracy of comparison with the value at the time of counting the game media is increased, and the detection accuracy of the goto action can be increased.

  If a gaming machine becomes non-operational, it is desirable to initialize the possession ball based on the judgment that it is a customer change. However, as a condition for the gaming machine to become non-operational, the number of possession balls has decreased. When a player purchases a game medium, the game ends when all of the balls are used up, or when a player plays with a small amount of balls from another table, and the player holds the ball Expected to take a break. In this case, in the former case, it is necessary to initialize the ball, but in the latter case, the ball cannot be initialized.

  Here, since the player receives the rental of the game medium in a state where a small amount (for example, 50 balls) of the ball is left, when the sales are generated in the state of a small amount of the ball as in the invention of claim 1. In the condition of initializing the holding ball, in the former case, the holding ball becomes non-operating in a state where it falls below zero. In other words, for example, if a game medium is lent out with 50 balls remaining, the actual number of balls is 175, whereas the calculation is 125 balls. If all balls are used up, the ball will be -50 balls, which is always below zero.

  Therefore, according to the second aspect of the present invention, the customer change detection means detects the customer when the holding ball calculated by the calculation means is not operating in a state of less than a second set value that is a predetermined value equal to or less than zero. Since alternation is detected, the accuracy of the holding ball can be improved without being affected by non-operation due to a break.

  As described above, fraud due to bringing game media can be detected based on the holding balls for each gaming machine calculated by the calculation means, but in order to further improve the accuracy of holding balls, It is necessary to make it.

  However, since it is difficult to accurately detect customer turnover, in the invention of claim 3, the third set value is higher than the first set value based on one unit of gaming media lending. When sales occur in the case of (for example, 1000 balls) or more, it is assumed that customer replacement has been performed. If such a condition is established, the player ends the game with a ball and then another player plays a new game with the game machine, or a prepaid card with a ball. Alternatively, since it is assumed that game media is purchased for the purpose of using up all of the cash (500 yen coins) on hand, it cannot be determined that the turnover is uniform.

  Therefore, according to the third aspect of the present invention, it is possible to input a customer change by the customer change input means, and when such an input is made, it is determined that the customer change has been made, and the calculation means calculates When the initializing means initializes the holding balls, the accuracy of the holding balls can be increased.

  According to the invention of claim 4, the handling of the ball from the time when the customer replacement estimation means estimates the customer change until the customer replacement input means confirms the customer replacement is different depending on whether the customer replacement or the game continues. From the guess of customer change until the customer change is confirmed, the holding ball will be the spare holding ball, in the case of customer change the spare holding ball will be the holding ball, and in the case of the game continuation, the holding ball will be the holding ball By adding to, the holding ball can be processed appropriately.

  In the invention of claim 4, when the spare holding ball is added to the holding ball, it is a continuation of the game, and it is impossible for the customer to be changed until the gaming machine is not in operation. In such a case, it is possible to prevent the estimation of useless customer replacement by not estimating the customer replacement until the gaming machine is not in operation.

Hereinafter, an embodiment in which the present invention is applied to a fraud detection system for a pachinko gaming machine will be described with reference to the drawings.
FIG. 1 schematically shows the overall configuration of a game hall fraud detection system. In FIG. 1, a plurality of pachinko gaming machines 1 are installed in the game hall. In addition, a call lamp unit (corresponding to customer replacement input means) 2 is installed above each pachinko gaming machine 1, and a ball between the pachinko gaming machine 1 adjacent to the pachinko gaming machine 1 for lending a pachinko ball as a gaming medium. A rental machine 3 is installed. In this case, the first repeater 4 is provided corresponding to each island, and the second repeater 5 is provided corresponding to each two call lamp units 2, and the pachinko gaming machine 1 and the stand The ball ball lending machine 3 is called with a management device (corresponding to calculation means, customer replacement estimation means, initialization means, fraud detection means, customer change detection means) 6 installed in the management office of the game hall. Data is transmitted / received via the lamp unit 2, the second repeater 5 and the first repeater 4. In addition, from the calling lamp unit 2 to the management device 6, a well-known sales signal (indicating the sales of the ball rental machine 3), an out ball signal (indicating the number of balls driven into the pachinko gaming machine 1), a safe ball A number signal (indicating the number of balls to be paid out from the pachinko machine 1) is output, a start signal (indicating the start of symbol variation), a jackpot signal (indicating that the jackpot is being hit), a probability variation signal (in the probability variation) Is output).

  In addition, when the pachinko gaming machine 1 is a CR machine, a CR unit is installed instead of the inter-ball ball lending machine 3. This CR unit has a function of lending a pachinko ball within a range of balance amount data stored in the prepaid card in a state where a prepaid card (not shown) is inserted. The pachinko ball lending operation by the CR unit is such that when a lending switch (not shown) provided on the pachinko gaming machine 1 side is operated, a release command is issued to the pachinko ball releasing mechanism in the pachinko gaming machine 1. It is done by giving. A sales signal indicating sales by a prepaid card is transmitted from the CR unit to the management device 6.

The voice management device 7 calls the income 8 carried by the employee in response to a command from the management device 6. The income 8 is carried by each employee and is composed of a receiving unit 8a and an earphone 8b, and outputs the sound received from the sound management device 7 from the receiving unit 8a to the earphone 8b.
When counting the inserted pachinko balls, the counter 9 performs fraud detection by collating the holding balls stored in the management device 6 with the counting balls.

When the remote control signal is input from the remote control device 10 carried by the employee through the calling lamp unit 2, the management device 6 processes the ball according to the type of the remote control signal as will be described later.
FIG. 2 shows a plane of the remote control device 10. In FIG. 2, various buttons are provided on the remote control device 10, and various commands can be transmitted to the management device 6 through the calling lamp unit 2, but in this embodiment, a “customer change” button 11 is provided. Only the [Continue] button 12 is used.

Next, the operation of the above configuration will be described.
Based on the signal output from the pachinko machine 1, the management device 6 manages the accumulated out, accumulated safe, accumulated sales, and player's possession for each pachinko machine 1 and detects fraud based on the possession. It is carried out.
FIG. 3 is a flowchart showing the operation of the management device 6. In FIG. 3, the management device 6 includes an out signal input process (S100), a safe signal input process (S100), a sales signal input process (S100), a remote control signal input process (S200), a timer confirmation process (S300), and a remote control. The signal input process (S400), the timer confirmation process (S500), and the fraud detection process (S600) are repeatedly executed.

When the player receives a pachinko ball rental from the daitama ball lending machine 3, a sales signal is output from the daima ball lending machine 3 to the management device 6.
FIG. 6 shows sales signal input processing of the management device 6. In FIG. 6, when the sales signal is input (S301: YES), the management device 6 increments the cumulative sales (S302), and the holding ball is the set value M (+125 balls, corresponding to the first set value). It is determined whether or not this is the case (S303). In this case, when the player receives a pachinko ball loan from the stand ball ball lending machine 3 to start the game, the current ball is zero (S303: NO). The ball is reset (S311), the game continuation flag is reset (S312), and the holding ball is incremented (S313). The game continuation flag is a flag indicating that the employee has confirmed the customer change as will be described later. Further, the spare holding ball is for holding a temporary holding ball until it is confirmed by the employee whether the customer changes or the game is continued as will be described later.

Here, since one unit of pachinko ball lending is 500 yen (125 balls), when a player rents a pachinko ball worth 500 yen, the current holding ball is 125 balls.
When the player further rents a pachinko ball, since the possession ball is 125 balls (S303: YES), it is confirmed that the customer replacement confirmation flag and the game continuation flag are reset (S304: (YES, S305: YES), after confirming that the ball is equal to or less than the set value N (+1000 balls, corresponding to the third set value) (S306: NO), the ball is incremented (S313). Therefore, when a player rents pachinko balls in units of 500 yen for playing a game, the number of holding balls corresponding to the pachinko gaming machine 1 increases by 125 balls.

When a player drives a pachinko ball that has been rented from the machine ball lending machine 3 into the pachinko gaming machine 1, the out ball is discharged from the pachinko gaming machine 1 and an out signal is output to the management device 6.
FIG. 4 is a flowchart showing the out signal input process of the management device 6. In FIG. 4, when an out signal is input (S101: YES), the management device 6 resets a non-operation timer (for example, 5 minutes) (S102) and increments the cumulative out (S103). This non-operation timer is for determining that the player has interrupted the game, and is always in an operating state.

Next, it is determined whether the customer change confirmation flag is reset (S104). This customer change confirmation flag is a flag indicating that the employee has been confirmed to confirm the customer change by the income 8 as will be described later. In this case, since the customer change confirmation flag is reset (S104: YES), the holding ball is decremented (S105).
When a pachinko ball driven into the pachinko gaming machine 1 wins, a safe ball is paid out from the pachinko gaming machine 1 and a safe signal is output to the management device 6.

FIG. 5 shows safe signal input processing of the management device 6. In FIG. 5, when the safe signal is input (S201: YES), the cumulative safe is incremented (S202), and it is confirmed whether the customer change confirmation flag is reset (S203). In this case, since the customer change confirmation flag is reset (S203: YES), the holding ball is incremented (S204).
With the basic operation as described above, the holding ball increases according to the input of the sales signal or the safe signal, and decreases according to the input of the out signal.

And the management apparatus 6 performs a fraud detection process based on the holding ball calculated | required as mentioned above.
FIG. 9 shows fraud detection processing of the management device 6. In FIG. 9, the management device 6 detects that fraud has occurred (S601: YES) when the possessed ball becomes less than the possessed ball abnormal value (−125 balls) (S601), and the voice management device 7 Is instructed to output the fraud detection voice of the corresponding machine number (S603). Accordingly, when the employee is notified of the machine number through the income 8, the employee goes to the pachinko machine 1 of the corresponding machine number to check whether the unauthorized movement due to the movement of the machine has been carried out. Handle appropriately.

  Now, the holding ball does not theoretically become zero or less. If the holding ball becomes zero or less (<± 0), the management device 6 may perform fraud detection, Since the accuracy of the holding ball decreases due to the factor, in the present embodiment, the holding ball has an abnormal value of the holding ball (− as described above in order to prevent the influence of the error while increasing the accuracy of the holding ball as follows. The fraud detection is performed when the number is less than 125 balls).

  That is, when the management device 6 determines in the sales signal input process whether the holding ball is greater than or equal to the set value M (+125 balls) in response to the input of the sales signal, the condition that the holding ball is less than the set value M For example, if a player moves a table with a small amount of balls (for example, 100 balls) and the next player rents a pachinko ball to play a game, or because the number of balls has decreased It is assumed that a player purchases pachinko balls. In the former case, it is necessary to reset the ball because it is a customer change, whereas in the latter case, it is not a customer change, so it is not necessary to reset the ball, but it is caused by moving the table. In order to prevent the error of the holding ball, the holding ball and the spare holding ball are reset (S311).

  Here, as described above, even when a player purchases a pachinko ball with a small amount of balls, the ball is reset, so that the actual ball at the time of resetting is generated as an error. That is, if the number of possessed balls after resetting is 124 balls, which is the maximum value less than the set value M, 124 balls become an error, and when the player digests all the possessed balls, the possessed balls are -124 balls. An error occurs. However, in this embodiment, since the fraud detection value is set to −125 balls as described above, even if the holding ball is reset in a state of less than the set value M, an error may cause fraud detection. There is no.

The set value M is one unit of pachinko ball lending (125 balls = 500 yen), the limit value of a small number of balls that can be silently moved, and further less than the absolute value of the fraud detection value. It is a condition.
Next, after the game continuation flag is turned off (S312), the holding ball is incremented according to the occurrence of sales (S313).

As a result of the above operation, when sales occur with a small amount of balls, the ball is considered to be zero by resetting the ball. The accuracy of the ball can be prevented and its accuracy can be improved, and it can be prevented that the error of the holding ball caused by the movement of the table with the holding ball causes trouble in the fraud detection.
Therefore, when the player moves a table with a large number of balls and runs out of all the balls, the ball is less than zero and is less than -125 balls, which is an abnormal value of the ball, and the management device 6 Can detect fraud in the fraud detection process.

  In addition, as a condition for generating a state in which the holding ball exceeds the set value N (+1000) when the sales signal is input, the player ends the game with the holding ball, and then the pachinko gaming machine In this case, it is assumed that another player plays a new game, or purchases pachinko balls for the purpose of using up the prepaid card or the cash on hand (500 yen coins) in a state where there is a ball. In the former case, it can be determined that the customer is changing, whereas in the latter case, it can be determined that the game is to be continued, so the employee needs to determine which case. The set value N is preferably set to +1000 balls in the present embodiment because it is desirable that the staff can judge at first glance whether or not the customer changes. Although the frequency of such determinations is low, if the processing is wrong, a large error occurs during counting.

  In the sales signal input process, the management device 6 sets a customer replacement confirmation flag (S307) when the holding ball exceeds the set value N when the sales signal is input (S306: YES), and the voice confirmation device 7 is instructed to output the sound for confirming the corresponding car number (S308), the confirmation timer is activated (S309), and the spare holding ball is incremented (S310). As a result, since the employee is notified of the machine number that may have been replaced by the customer through the income 8, the employee operates the remote controller 10 after confirming whether the customer is switched or the game is continued. That is, the player's possession ball is confirmed, and when the possession amount is small, it is determined that the customer is alternate and the “customer interchange” button 11 of the remote control device 10 is operated. If there are a lot of balls, it is determined that the game is to be continued and the “continue” button 12 of the remote control device 10 is operated.

  As described above, when the sales signal is input in the state where the customer replacement confirmation flag is set in the sales signal input process, the customer replacement confirmation flag is set (S304: NO). Increment (S310). Further, when the safe signal is input in the safe signal input process, since the customer replacement confirmation flag is set (S203: YES), the spare holding ball is incremented (S204). Further, when an out signal is input in the out signal input process, the customer replacement confirmation flag is set (S104: NO), so the reserve ball is decremented (S106). Accordingly, it is possible to obtain a spare ball that is a temporary ball after the customer change confirmation flag is set.

When the employee operates the remote control device 10 as described above, the management device 6 executes a predetermined process in the remote control signal input process.
FIG. 7 shows remote control signal input processing of the management device 6. In FIG. 7, when the remote control signal is input (S401: YES), the management device 6 resets the holding ball (S403) if the remote control signal is a customer turnover (S402: YES). The game continuation flag is reset (S404).

Next, after confirming that the customer turnover confirmation flag is set (S405: YES), the spare holding ball is added to the holding ball (S406). Thereby, the spare holding ball which is a temporary holding ball after the customer change confirmation flag is set becomes the holding ball.
Next, the reserve ball is reset (S407), the confirmation timer is stopped (S408), and the customer replacement confirmation flag is reset (S409).

On the other hand, if the received remote control signal is not a customer change (S402: NO), it is confirmed that the customer change confirmation flag is set (S410: YES) and after confirming that the remote control signal is continuous. (S411: YES), the game continuation flag is set (S412).
Next, the spare holding ball is added to the holding ball (S406), and the preliminary holding ball is added to the holding ball (S407). As a result, the temporary spare ball after the customer change confirmation flag is set is added to the ball.

Next, the reserve ball is reset (S407), the confirmation timer is stopped (S408), and the customer replacement confirmation flag is reset (S409).
When the employee's operation on the remote control device 10 is instructed to change the customer or continue the game, the temporary spare ball after the customer change confirmation flag is set according to the instruction is given. Are handled appropriately.

  Here, when the customer change confirmation flag is set as described above, the management device 6 responds to the fact that the game continuation flag is set even if sales occur in the sales signal input process (S305: NO), it is not determined whether the holding ball exceeds the set value N. The game continuation flag is reset under the following conditions: sales occur when the number of balls is less than the set value M, a customer replacement signal is received from the remote controller 10, or a non-working timer is up in the timer confirmation process. As a result, it is possible to prevent a customer change prediction being wasted every time sales are made despite the continuation of the game.

Now, when the customer turnover confirmation flag is set, a rapid remote control operation by an employee is necessary, but when the remote control operation is not performed, the following processing is performed.
FIG. 8 is a flowchart showing the timer confirmation process of the management apparatus 6. In FIG. 8, when the confirmation timer has timed out with the customer change confirmation flag set (S506: YES), the management device 6 treats the game as continuing and proceeds to step S412 of the remote control signal input process. Thus, the continuation process is performed in the same manner as described above. Therefore, when the customer change is not instructed by the employee at the time of the customer change, it will be handled as a continuation of the game and a large error will occur, so the employee was instructed to confirm the customer change at the income 8 If it is necessary to perform confirmation work quickly.

On the other hand, in the timer confirmation process, when the player interrupts or ends the game, the non-operation timer expires (S501: YES). In such a case, the game continuation flag is reset (S502).
Next, it is determined whether the holding ball is less than a set value L (± 0, corresponding to the second set value) (S503). In this case, the condition of non-operation when the possession ball is less than the set value L is that, as described above, since the player has purchased pachinko balls because the number of possession balls has decreased, the game is performed using all of the possession balls. It is assumed that the game is ended or a game is played with a small amount of balls from another table. In both cases, since it is necessary to reset the holding ball, the holding ball is reset (S504). In addition, since there are many cases where the player temporarily leaves the pachinko gaming machine 1 in a state where there is a ball, if the ball is equal to or greater than the set value L (S503: NO), it is not possible to reset the ball Absent.

  The setting value M is set to +125 balls, and the setting value L (± 0) is set. When the setting value M is set to ± 0 balls, for example, the player moves to another table with 100 balls. However, if another player who has played with the pachinko machine 1 moves to another table with 100 balls, 200 balls will be generated as an error at that time. This is because it may become large. In other words, in this embodiment, it is possible to prevent the error of holding ball by resetting the holding ball for bringing in less than 125 balls, and it is possible to change customers when sales occur In order to reflect the fact that the possibility of continuation of the game is high when it becomes non-operating, the setting values associated with each are made different.

  According to such an embodiment, when sales are generated at a predetermined set value N (+1000) or more of one unit or more of pachinko ball lending, it is assumed that the customer is changed, and the possession from the timing is estimated. The ball is used as a spare ball, and when a customer turn is input by an employee's remote control, the spare ball is used as a held ball, and when a game continuation is entered, the spare held ball is added to the held ball. It is possible to increase the accuracy of the holding balls when sales occur with a large amount of balls. Therefore, as a result of improving the accuracy of the holding ball, the comparison with the count value at the time of counting becomes accurate, and the detection accuracy of the goto action can be increased.

  In addition, when the ball is less than the predetermined set value M (+125) of 1 unit or less of the pachinko ball lending, it is determined that the customer is changing and the ball is reset. It is possible to increase the accuracy of the holding balls when sales occur in the state. In this case, since the fraud detection value is set to −125 balls, even if the player purchases pachinko balls with a small amount of balls, the fraud detection value does not fall below the fraud detection value. It is possible to prevent erroneous detection of fraud detection due to the error of the ball.

In addition, since the ball is reset when the ball is not in operation when it is below zero, it can cope with the error of the ball due to the movement of the table with a small amount of ball, Can improve the accuracy.
Therefore, since it is possible to cope with the error of the ball due to various factors as described above, it is possible to improve the accuracy of the ball and reliably deal with an illegal carrying of the ball.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows.
The calling lamp unit 2 may be provided with a “customer” change button and a “continue” button.
A sensor that detects the presence of a pachinko ball on the upper plate of the pachinko gaming machine 1 may be provided, and it may be determined whether the customer changes or the game continues based on the detection state of the sensor.
As means for notifying the confirmation of the customer change, in addition to the income 8, it may be displayed (for example, pop-up display) or printed on the monitor of the management device 6.
The present invention may be applied to a pachislot machine.
