Description

  The present invention relates to a technique for collecting various kinds of information for adjusting nails of a game machine installed in a so-called game hall from the game machine.

  A so-called game hall that conducts business by setting a large number of game machines and playing them on the game machine is widely known. When starting a game in this game hall, first pay a fee, borrow a plurality of game balls from the game hall, and then select your favorite game machine from among the many game machines installed. . Subsequently, the previously borrowed game ball is thrown into the game stand, and the game is played by firing the game ball on the game board surface. A plurality of winning holes are provided on the gaming board surface of the gaming table, and a predetermined number of gaming balls are paid out from the gaming table as winning balls each time a gaming ball enters the winning hole. Yes. The game balls that have been paid out can be used again in the game, but it is not so easy to make the game balls enter the winning opening. Therefore, it is normal that the number of game balls decreases as the game continues. When all the game balls are used up, the game can be continued by paying the fee again and borrowing the game balls. If the game is to be stopped before the game balls are used up, the remaining game balls are returned to the game hall. At this time, the player can receive a prize according to the number of game balls.

  The management of such a game hall is based on the number of game balls rented to the player and used for games rather than the number of game balls paid out as prize balls from the game stand (sometimes called safe numbers). If it is more than a certain number (sometimes called the out number), it will not hold. Note that the number of game balls obtained by subtracting the safe number from the out number may be referred to as a “difference ball”. In order to secure more than a certain number of difference balls, the safe number may be reduced. On the game board surface of the game stand, in addition to a plurality of winning holes, there are also obstacle nails (sometimes referred to simply as “nails”) for adjusting the ease of entering each winning hole. By adjusting this obstacle nail and making it difficult for the game ball to enter the winning opening, it is possible to suppress the safe number. However, if the number of safes is reduced too much, the player will soon get bored with the game, and the game will be stopped. As a result, the number of outs will be reduced, and a certain number of difference balls cannot be secured.

  Therefore, the so-called Seven machine (or Fever machine) is the most widely used type of game machine in recent years, and the number of start times (average start number) when a certain number of game balls are fired is an appropriate value. It has been proposed to adjust the nail so as to be (Patent Document 1). This type of game machine, called a “seven machine”, has a special winning opening (called “big winning opening” or “attacker”) that is normally closed so that game balls cannot enter, and a start opening. There are provided a special prize opening called “symbol” and a symbol display device for variably displaying various symbols. When the game ball wins at the start opening, the symbol display is started on the symbol display device. After that, when a specific symbol (winning symbol) is stopped and displayed, the attacker opens for a certain period of time, so-called a special prize. It becomes a state. It is possible to easily enter the game ball into the open attacker, and the player can acquire a large number of game balls in the special prize state. In such a seven machine, the player plays a game for the purpose of generating a special prize state. The customer immediately stops the game, and as a result, the number of outs decreases and it becomes difficult to secure the difference ball. On the other hand, when the variable display of the symbol is started, a special prize state is generated with a certain probability and a large number of game balls are paid out. If the number of start of the variable display (start count) becomes too large, this time, The number increases and it becomes difficult to secure the difference ball. After all, by adjusting the nail so that the average number of start times when a certain number of game balls are fired becomes an appropriate value, the safe number is suppressed without reducing the number of outs, a difference of a certain number or more It is possible to secure a ball. In addition, the nails are adjusted in the same manner for game machines of a type other than the seven machines that display symbols in a variable manner.

Japanese Examined Patent Publication No. 6-104143

  However, as the business environment surrounding the game hall becomes more severe, there is a problem that it is becoming difficult to perform proper nail adjustment if the nail adjustment is performed based on the average number of start times. In other words, in recent years, players have been strictly selecting game halls where winning balls can be easily earned, and game halls tend to attract players by reducing the difference to the point where profits can be made. Yes. However, even if the nail adjustment is performed so that the average number of starts is slightly higher to attract the players, the number of players is actually not increased. When the nail adjustment was performed so that the average number of starts was slightly lowered to reduce the number of safes, the player flowed into another game hall and the number of outs was reduced. It's not uncommon to see a significant decline and a deficit. As described above, with the conventional method based on the average number of start times, it is difficult to perform high-precision nail adjustment that reduces the difference ball to the limit while ensuring the minimum profit, and therefore higher There is a strong demand for the development of technology that can perform nail adjustment with high accuracy.

  The present invention has been made in response to the above-described problems in the prior art, and an object of the present invention is to provide a technique capable of performing nail adjustment of a large number of game tables with high accuracy as the entire game hall.

In order to solve at least a part of the above-described problems, the gaming machine information collecting apparatus of the present invention employs the following configuration. That is,
A game board is launched by launching a game ball on a game board provided with a start opening where a game ball can be won, and a symbol display device that starts a variable display of the game triggered by the winning of the game ball at the start opening. A gaming machine information collection device that is connected to a gaming machine to perform and collects gaming machine information related to the operating status of the gaming machine,
An operation time detecting means for detecting an operation time which is an accumulated time during which a game is played on the game table;
Out number collecting means for collecting the number of outs which is the number of game balls fired on the game board surface;
Starting winning information collecting means for collecting starting winning information indicating that a game ball has won at the starting opening;
Symbol variation information collecting means for collecting symbol variation information indicating that the symbol is variably displayed on the symbol display device;
Based on the number of fluctuations of the symbol obtained from the symbol fluctuation information and the number of outs, an average fluctuation number acquisition means for acquiring an average fluctuation number that is the number of fluctuations per unit out number;
Each time the start winning information is received, the number of balls to be held is incremented by one with a predetermined upper limit as a limit, and the number of balls to be retained is subtracted by one each time the symbol variation information is received. Average number of reserved balls acquiring means for acquiring an average number of reserved balls that is a time average value within the working hours ;
And said average variation time count, a first ratio 較手 stage for comparing the first reference defined with respect to said mean variation time count,
Said average hold piece count, the second ratio 較手 stage for comparing a second reference that is defined with respect to the average hold piece count,
The gist of the invention is to include output means for outputting information on the necessity of nail adjustment of the game table based on the comparison result by the first comparison means and the comparison result by the second comparison means .

In such a gaming machine information collection device of the present invention, by collecting gaming machine information such as the number of outs, starting winning information, symbol variation information , operating time, etc., the average number of fluctuations and the average number of balls on hold are acquired. . Then, the obtained average number of fluctuations is compared with a predetermined first standard, and the average number of reserved balls is also compared with a predetermined second standard, with the average number of fluctuations and the first standard. Based on the comparison result (first comparison result) and the comparison result (second comparison result) between the average number of reserved balls and the second reference (second comparison result) , information on the necessity of nail adjustment of the game table is output. To do. Various known methods can be used as a method for detecting the operation time. For example, since the number of game balls that a game table fires per unit time is determined (typically 100 balls per minute), the number of outs detected for the game table is out in the number of game balls per unit time. The operating time can be detected by dividing the number. Alternatively, the operating time is detected by determining the reference number of game balls per unit time (for example, 10 balls per minute) and detecting whether or not the reference number of game balls is exceeded. Also good. For example, if the number of outs detected per minute exceeds 10, it is determined that the game has been played for that one minute. In this way, the operating time may be detected by accumulating the time when the number of outs exceeds the reference number of game balls for each reference time.

The detailed mechanism will be explained in detail later, but the number of symbols on the symbol display device tends to increase as the number of reserved balls increases, but the increase in the number of reserved balls directly leads to an increase in the number of symbol variations. Do not mean. That is, it is considered that the holding balls can be increased or decreased without significantly affecting the number of symbol fluctuations of the symbol display device. On the other hand, the presence / absence of the holding ball is likely to be noticed by the player who plays the game on the game stand, and is considered to have a great influence on the psychology of the player who plays the game. Focusing on these points, even if it is a delicate nail adjustment that is difficult to realize based on the number of symbol fluctuations of the symbol display device, it can be performed appropriately and accurately if it is performed based on the average number of balls held. possible it is. Therefore, based on the first comparison result that compares the average number of fluctuations with the first reference and the second comparison result that compares the average number of reserved balls with the second reference, information on the necessity of nail adjustment is obtained. If they are output, by referring to these, it is possible to appropriately determine whether or not nail adjustment is necessary for the game table, and to easily perform fine nail adjustment with high accuracy.

In addition, in the gaming machine information collection device of the present invention described above , the nail adjustment of the gaming machine is required when the average number of fluctuations is larger than the first reference and the average number of balls held is smaller than the second reference. This information may be output .

Although the detailed mechanism will be described later, a gaming table with a small average number of balls to be held tends to get bored by the player, and the number of outs tends not to increase. In addition, game machines having a large average number of fluctuations tend to increase the number of game balls paid out (so-called safe numbers). Accordingly, it is considered that nail adjustment is necessary for a gaming machine with a small average number of balls to be held and a large average number of fluctuations because the gaming hole is likely to be in the red. Therefore, if the information indicating that the nail adjustment of the game table is necessary is output when the average number of fluctuations is larger than the first reference and the average number of balls to be held is smaller than the second reference, Necessary game machines can be easily found.

Moreover, in the gaming machine information collection device of the present invention described above, the gaming value is an index related to the sales result for each gaming machine, by connecting to a plurality of gaming machines and collecting gaming machine information for each gaming machine. And information on the necessity of nail adjustment may be output. Here, as an indicator (sales value) related to the business results, it is not necessary that the business value is uniquely determined by determining the business value. It is an index that increases or decreases. As such an index, for example, an out number, a safe number, a difference ball (= out number−safe number), an operating time, a sales amount, and the like can be used.

If you output the business value such as the number of outs and information on the necessity of nail adjustment for each game machine, by comparing the results for multiple game machines, the game machine to be adjusted nail, It is possible to easily and appropriately find out from a plurality of game tables, and as a result, it is possible to accurately perform nail adjustment as a whole game hall. In addition to the information on the necessity of nail adjustment, if the comparison result with the first reference and the comparison result with the second reference are also output, the operating value such as the number of outs, Since the comparison result with the first criterion and the comparison result with the second criterion can be compared, the following effects can also be obtained. That is, depending on the type of gaming machine and the difference in the tendency of players visiting the gaming hall, the comparison result between the first standard and the second standard may not be considered in the same way, There may be cases where the nail should be adjusted mainly considering the comparison result, or where the nail should be adjusted mainly considering the comparison result with the second reference. Even in such a case, the business value, the comparison result of the first standard, and the comparison result of the second standard can be compared for a plurality of game machines. As a result, the nail can be adjusted appropriately and accurately.

A. Device configuration :
A-1. overall structure :
FIG. 1 is an explanatory diagram showing the overall configuration of the gaming machine information collection device 100 of this embodiment installed in a gaming hall. As is well known, a large number of game machines are installed in the game hall, and a predetermined number of these game machines are arranged in a lump. A group of such game machines is called an “island”. In addition, a ball catching facility for supplying game balls to the game tables and collecting game balls discharged from the game tables is also provided for each island. In FIG. 1, only three islands 10 installed in the game hall are displayed. In addition, in order to avoid illustration becoming complicated, illustration is abbreviate | omitted about the catching equipment of each game stand 20. FIG. In addition, each gaming table 20 constituting the island 10 is equipped with a control computer, and the contents of the games played on each gaming table 20 are controlled by this computer.

  As shown in FIG. 1, the gaming machine information collection device 100 of the present embodiment includes a platform unit 110 that receives various types of information from a computer mounted on each gaming machine 20, and an island that relays information from the platform unit 110. The unit 120 and the hall computer 130 that receives information from the island unit 120 are configured. Among these, the base unit 110 is provided in a ratio of one to a predetermined number of game machines 20 and is connected to each game machine 20 by a communication cable. One island unit 120 is provided on each island 10 and is connected to each unit 110 provided on the island 10 by a communication cable. Furthermore, only one hall computer 130 is provided in the game hall, and is connected to the island units 120 provided on each island 10 by a communication cable. Therefore, information from all the game tables 20 installed in the game hall is collected in the hall computer 130 via the table unit 110 and the island unit 120. In the following, the contents of the information (game table information) output from the game table 20 and collected in the hall computer 130 will be described. As a preparation, the content of the game performed on the game table 20 will be briefly described. .

A-2. Overview of the game:
FIG. 2 is an explanatory view illustrating an outline of the game table 20 installed on the island 10. As shown in the drawing, a large game board 21 for launching a game ball and playing a game is provided at the center of the game table 20. In addition, a symbol display device 22 composed of a liquid crystal screen is provided in the approximate center of the substantially circular game board 21, and various symbols are variably displayed on the liquid crystal screen. It is possible to stop at any symbol. Below the symbol display device 22, a special winning port called a start port 23 is provided. Below the start port 23, a special winning port called an attacker 24 is provided, and at the bottom of the game board 21. Is provided with an outlet 25 through which game balls are discharged. The game board 21 is provided with a winning opening other than the start opening 23 and the attacker 24, obstacle nails, windmills, etc., but these are not shown.

  Further, below the game board 21, there is provided a portion called an upper plate 27 for throwing in a game ball to start a game, and below that, a game ball paid out as a prize ball is stored. A part called a lower plate 28 is provided.

  When starting a game on the gaming table 20, after borrowing game balls by inserting cash or a prepaid card into the ball lending machine 30 installed adjacent to the gaming table 20, Put in the dish 27. Then, when the launch handle 29 provided at the lower right corner of the game table 20 is rotated clockwise, the game balls thrown from the upper plate 27 are directed to the game board 21 one by one with strength according to the rotation angle. Fired. The launched game ball is launched onto the top of the game board 21 and then flows down on the board surface of the game board 21 by gravity. As described above, since the game board 21 is provided with a plurality of obstacle nails, the game ball collides with the obstacle nails and flows down the game board 21 while changing the course in a complicated manner. On the way, a certain game ball wins a winning opening, and other game balls are discharged out of the gaming table 20 through the out opening 25. The game balls won in each winning opening and the game balls discharged from the out opening 25 are collected by the above-described catching equipment. At this time, the game balls from each gaming stand 20 are provided for each stand. It is counted for each table by an out ball meter (not shown).

  On the other hand, when a game ball flowing down the game board 21 wins any one of the winning openings, a control computer provided in the game table 20 detects this, and a predetermined number of game balls are used as a prize ball in the upper plate 27. To be paid out. The game stand 20 pays out the game balls stored in the inside as prize balls, but each time the number of game balls inside decreases, the game balls are replenished from the above-described catching equipment. At this time, the game balls replenished from the ball catching facilities to the respective game tables 20 are counted for each table by a safe ball meter (not shown) provided for each table.

  Further, when the winning opening where the game ball has been won is the start opening 23, the control computer of the gaming table 20 starts displaying the symbols on the symbol display device 22, and then stops displaying any symbol. Let At this time, when a predetermined winning symbol (for example, a symbol of “777”) is stopped and displayed, a special prize state is established for a predetermined period and the attacker 24 is released. On the other hand, if the symbol that is stopped and displayed is not a winning symbol, the attacker 24 remains closed. In addition, when a game ball wins at the start port 23 during the symbol change display, the winning is stored as a holding ball, and when the symbol displayed in a stopped state is not a winning symbol, the winning ball is stored. Based on this, the symbol variation display is started. It is possible to store up to the upper limit number (typically 4 or 8) of the hold balls, but with the upper limit number of hold balls being stored, the game balls are awarded to the start opening 23. However, the prize is not stored as a reserve ball. The number of reserved balls stored is displayed on the liquid crystal screen of the symbol display device 22, or a dedicated lamp is turned on so that the player can immediately grasp the number.

  On the other hand, when the attacker 24 is released, it is possible to easily win the game balls, and the winning balls are paid out each time the winning is made, so that it is possible to acquire many game balls. Whether or not the symbol display is stopped and displayed on the symbol display device 22 is determined in advance by a lottery performed internally by the control computer when the symbol variation display is started. There are two states, the probability of winning a win in an internal lottery, the state of normal probability, and the state of higher probability than the normal probability. The game is advanced while appropriately switching the state. The state that is won with a high probability is called a “probability variation state” or simply a “probability variation state”. Therefore, if a game ball can be won at the start port 23 during the probability variation state and the symbol variation display can be started, it is possible to generate a special prize state with a high probability and obtain a large number of prize balls. ing.

A-3. Game table information flow:
FIG. 3 is a block diagram showing a flow of game table information collected from the game table 20 to the hall computer 130 via the table unit 110 and the island unit 120. As shown in the figure, from the gaming table 20, a start winning pulse, a symbol variation pulse, a special prize flag, and a probability variation flag are output to the platform unit 110. Here, the start winning pulse is a pulse signal that is output one pulse at a time when a game ball wins at the start port 23. The symbol variation pulse is a pulse signal that is output one pulse at a time each time symbol variation display (symbol variation) is performed on the symbol display device 22. The special prize flag is a flag that is set to a high state (H) when the gaming machine 20 is in a special prize state, and is set to a low state (L) when the gaming machine 20 is not in a special prize state. Further, the probability change flag is a flag that is set to the High state (H) when the gaming machine 20 is in the probability change state and set to the Low state (L) during the normal state.

  In addition, as described above, the ball catching facility is provided with an out ball meter and a safe ball meter for each game table 20, and the out ball meter counts out balls discharged from the game table 20, and the safe ball meter. Then, the safe balls replenished to the game table 20 are counted. Then, as shown in FIG. 3, every time the out sphere meter counts 10 out spheres, a pulse signal (out sphere pulse) is output for each pulse toward the base unit 110. Each time the safe sphere meter counts 10 safe spheres, a pulse signal (safe sphere pulse) of one pulse is output toward the base unit 110.

  When the table unit 110 receives the above game table information from the game table 20 and the ball catching equipment (out ball meter, safe ball meter) provided for each game table 20, the table unit 110 identifies the game table 20. Is output to the island unit 120 in combination with the identification information. Subsequently, when the island unit 120 receives the game table information from the table unit 110, the island unit 120 outputs the information to the hall computer 130 with information for identifying the island 10 further added. When the hall computer 130 receives the game table information output in this way, it identifies which island 10 is the game table information sent from the island unit 120 from the information added by the island unit 120. Based on the combined identification information, it is possible to identify which gaming table 20 in the island 10 is the gaming table information. The hall computer 130 collects game table information for one day for each gaming table 20 by performing the processing described below while identifying all the gaming tables 20 installed in the gaming hall.

B. Game table information collection processing:
FIG. 4 is a flowchart showing game machine information collection processing performed by the hall computer 130 to collect game machine information for each game machine 20. This process is a process that is always executed before the daily operation of the game hall is started.

  As shown in the figure, in the gaming machine information collection process, first, gaming machine information is initialized (step S10). That is, when starting business on a single day, game machine information about each game machine 20, a built-in timer, and the like are initialized in advance. When the initialization of the game table information is completed, the collection of the game table information for each game table 20 is started as follows.

  When collecting the game table information, first, an out number accumulation process is performed (step S20). In this process, it is determined whether or not an out ball pulse has been received from any of the game tables 20, and if an out ball pulse has been received, the base unit 110 and the island unit 120 with respect to the out ball pulse. Based on the information added in (1), the gaming machine 20 that has output the out ball pulse is identified. Then, “10” is added to the number of outs for the identified gaming machine 20. That is, as described above with reference to FIG. 3, the out ball pulse is output by one pulse every time 10 game balls are discharged, so the number of outs of the gaming table 20 that has output the out ball pulse is 1 pulse. "10" is added for each. On the other hand, if an out ball pulse has not been received from any of the game machines 20, the out number accumulation process is immediately terminated and the process proceeds to the next process. In this way, in the out number accumulation process, when an out ball pulse is received, the gaming machine 20 that has output the pulse is identified, and the number of outs is accumulated for each gaming machine 20.

  When the out number accumulating process is completed, the safe number accumulating process is subsequently performed (step S30). In the safe number accumulation process, a process of accumulating the safe number is performed for each gaming machine 20. That is, when the safe number accumulation process is started, it is determined whether or not a safe ball pulse is received from any of the game machines 20. If a safe ball pulse has been received, the gaming machine 20 that has output the safe ball pulse is identified, and “10” is added to the safe number of the gaming machine 20. Here, “10” is added to the safe number because, as described above with reference to FIG. 3, the safe ball pulse is output by one pulse every time 10 game balls are replenished. On the other hand, if a safe ball pulse has not been received from any of the gaming tables 20, the safe number accumulation process is immediately terminated and the process proceeds to the next process. In this way, in the safe number accumulation process, each time a safe ball pulse is received, the gaming machine 20 that has output the pulse is identified, and the safe number is accumulated for each gaming machine 20.

  After the safe number accumulation process, a special prize number accumulation process is performed (step S40). In the special prize number accumulation process, a process of accumulating the number of times of the special prize state described above for each gaming machine 20 is performed. That is, as described above with reference to FIG. 3, when the gaming machine 20 is in the special prize state, the special prize flag is switched from the low state to the high state. Therefore, in the special prize number accumulation process, the special prize flag is switched from the low state to the high state. It is determined whether or not there is a replaced gaming table 20. If such a gaming table 20 exists, after identifying the gaming table 20, “1” is added to the number of special prizes of the gaming table 20. In this way, in the special prize number accumulation process, the gaming machine 20 in which the special prize flag is switched from the low state to the high state is identified, and the special prize number is accumulated for each gaming machine 20.

  When the special prize number accumulating process is finished, the probability variation state detecting process is started (step S50). In this process, based on the probability change flag output from the gaming table 20, the number of times of switching to the probability changed state (number of times of probability change) and the elapsed time that the game was played in the probability changed state are accumulated for each gaming table 20. I do. As described above with reference to FIG. 3, when the gaming table 20 is switched from the normal state to the probability change state, the probability change flag is switched from the low state to the high state, and when the probability change state ends and returns to the normal state, the probability change flag is also changed. Return from the High state to the Low state. Accordingly, the gaming machine 20 in which the probability change flag is switched from the low state to the high state is detected, and “1” is added to the number of probability changes for the gaming machine 20, and the gaming machine 20 in which the probability change flag is in the high state. Then, processing for accumulating the duration of the probability variation state is performed.

  When the probability variation state detection process is completed, the hold related information detection process is started (step S100). As will be described in detail later, in this hold-related information detection process, various kinds of information (holding-related information) relating to the occurrence status of the hold on each gaming machine 20 is received by receiving game machine information such as a start winning pulse and a symbol fluctuation pulse. In addition, processing for detecting the number of winning prizes, the number of symbol variations (the number of times symbol variation display is started and stopped by the symbol display device 22), and the like are performed.

  When the hold related information detection process is finished, it is determined whether or not the business for one day is finished (step S60). If the business has not ended (step S60: no), the process returns to step S20, and after performing the aforementioned out number accumulation process, the subsequent safe number accumulation process (step S30), the special prize number accumulation process (step S40) Probability change state detection processing (step S50) and hold related information detection processing (step S100) are performed, and it is determined again whether or not the business has ended (step S60). In this way, in the gaming machine information collection process, when the gaming machine information is initialized when starting business on the 1st (step S10), the process from the number-of-outs cumulative process to the hold-related information detection process is terminated until the business is terminated. While repetitively executing a series of processes, the gaming machine information about each gaming machine 20 is collected.

  FIG. 5 is a flowchart of the hold-related information detection process (step S100) performed to detect various types of information related to the hold in the gaming machine information collection process. As shown in the figure, when the hold-related information detection process is started, first, it is determined whether or not a start winning pulse has been received from any of the game machines 20 (step S102). As described above with reference to FIG. 3, the start winning pulse is a pulse signal that is output by one pulse each time a game ball enters the start port 23.

  If the start winning pulse has been received (step S102: yes), the gaming machine that has output the start winning pulse based on the identification information added to the start winning pulse by the base unit 110 and the island unit 120. After identifying 20 (step S104), “1” is added to the number of start winnings of the identified gaming machine 20 (step S106). Subsequently, it is determined whether or not the number of balls on the gaming table 20 has reached an upper limit (here, “4”) (step S108). As a result, when it is determined that the number of balls on hold has not reached the upper limit (step S108: no), “1” is added to the number of balls on hold of the gaming table 20 (step S110). On the other hand, when the number of balls to be held has already reached the upper limit (step S108: yes), “1” is added to the overflow number of the gaming table 20 (step S112). In other words, the number of overflows means the number of start winnings that occurred when the suspension reached the upper limit.

  As described above, in the hold-related information detection process shown in FIG. 5, when the start winning pulse is received from any of the gaming tables 20 (step S102: yes), “1” is added to the start winning number (step S102). S106), a process of adding “1” to either the number of reserved balls or the number of overflows (step S110 or step S112) is executed for each gaming table 20. On the other hand, if it is determined that no start winning pulse has been received from any of the gaming tables 20 (step S102: no), the above-described series of processing (steps S104 to S112) are all skipped. In this embodiment, as described above, the processing for counting the number of reserved balls and the number of overflows for each gaming machine 20 will be described as being performed by the hall computer 130. However, the machine unit 110 performs these processes. The hall computer 130 may receive the result via the island unit 120.

  In the hold-related information processing, subsequently, it is determined whether or not a symbol variation pulse from any of the game machines 20 has been received (step S114). As described above with reference to FIG. 3, the symbol variation pulse is a pulse signal that is output one pulse at a time each time symbol variation display is started on the symbol display device 22.

  If the symbol variation pulse has been received (step S114: yes), the gaming machine 20 that has output the pulse is identified based on the identification information for the symbol variation pulse (step S116), and then identified. “1” is added to the number of symbol fluctuations of the game table 20 (step S118). Subsequently, “1” is subtracted from the number of reserved balls in the gaming table 20 (step S120). On the other hand, if it is determined that no symbol variation pulse has been received from any of the gaming tables 20 (step S114: no), the gaming table 20 is identified and the number of symbol variations is added, and the number of reserved balls is subtracted. A series of processing (steps S104 to S112) is skipped.

  As described above, when the start winning pulse is received, the number of balls to be held is incremented by 1 until the number of balls to be held reaches the upper limit (steps S102 to S112), and when the symbol fluctuation pulse is received, By decrementing the number of balls to be held by one (step S120), it is possible to detect the state of the hold for each gaming table 20.

  Therefore, in the hold-related information detection process shown in FIG. 5, as the last process, a process of accumulating the duration time of the hold state for each gaming machine 20 is performed (step S122). That is, it is detected whether the number of balls to be held is 0 to 4 for all the gaming tables 20 installed in the game hall, and after performing the previous holding related information detection processing, The elapsed time until the hold-related information detection process is performed can also be measured by the built-in timer of the hall computer 130. Therefore, for the gaming machine 20 with the number of balls on hold of 0, the elapsed time measured by the built-in timer is added to the duration of the number of balls on hold of 0. In addition, for a gaming machine 20 with one reserved ball, the elapsed time is added to the duration of one reserved ball. In step S122, a process of accumulating elapsed time in the duration of the number of reserved balls detected in each gaming machine 20 is thus performed. In addition, in the case where the number of reserved balls is 0, unlike the case where the number of reserved balls is one or more, there are a state in which the display of the symbols is changed and a state in which the changes are not displayed. . Therefore, in the case where the number of balls to be held is zero, the duration time may be accumulated in a state where these two states are separated.

  As described above, in addition to the hold-related information such as the number of balls to be held, the number of overflows, the duration of the number of balls to be held, and the gaming machine information such as the number of winning winnings and the number of symbol fluctuations is obtained for each gaming machine 20. Then, the hold related information detection process shown in FIG. 5 is terminated, and the process returns to the gaming machine information collection process of FIG.

  As described above, in the gaming machine information collection process of FIG. 4, when returning from the hold-related information detection process (step S100), it is determined whether or not the business has ended (step S60), and until the business is ended as described above. While repeating the out number accumulation process (step S20), the safe number accumulation process (step S30), the special prize number accumulation process (step S40), the probability variation state detection process (step S50), and the hold related information detection process (step S100), Game table information about the game table 20 is collected. If it is determined that the business has ended (step S60: yes), the gaming machine information collected for each gaming machine 20 is stored (step S70), and then the gaming machine information collection process of FIG. 4 is terminated.

  FIG. 6 is an explanatory diagram illustrating a part of the gaming table information obtained for each gaming table 20 by the gaming table information collecting process. As shown in the figure, the game table information includes various numbers such as the number of outs, the number of safes, the number of special prizes, the number of certain variations, the number of symbol variations, etc. Item data is stored. In addition, the “pending 0 hour” displayed in FIG. 6 is the duration of the game when the number of balls on hold is zero (the player plays a game with the number of balls on hold zero). And includes the time during which the symbol variation display is performed and the time when the variation display is stopped). Similarly, “hold 1 hour” is the duration of the state where the number of balls held is one, “hold 2 hours” is the state where the number of balls held is two, and “hold 3 hours” is the ball held The number is 3, and “hold 4 hours” is the duration of the state where the number of balls held is four. In addition, although not shown in FIG. 6, the time during which the game is played on the game table 20 (operation time) and the time when the variable display of the symbol display device 22 is further stopped during the holding time of 0 hours. Data on (stop time) is also included. In step S70 of the gaming machine information collection process shown in FIG. 4, a process of storing such gaming machine information in a large-capacity external storage device connected to the hall computer 130 is performed.

  In the gaming hall, the average fluctuation number for each gaming machine 20 (corresponding to the average start number in the prior art) is calculated from the gaming machine information obtained for each gaming machine 20 in this way, and the average fluctuation is calculated. For the game table 20 with a low number of times, adjust the nail to loosen the nail so that the game ball can easily win the start opening 23, and conversely, for the game table 20 with a high average fluctuation frequency, adjust the nail to tighten the nail. It is normal to do. However, as mentioned above, as the management environment surrounding the gaming hall becomes more severe, the nails that increase the safe number as much as possible while securing the marginal difference (= “out number”-“safe number”) that does not become deficit Adjustment is required, and such nail adjustment with high accuracy is difficult if nail adjustment is performed based on the average number of fluctuations. Therefore, in the gaming machine information collecting apparatus 100 of the present embodiment, the gaming machine 20 that requires nail adjustment by performing the following nail adjustment table generation processing based on the gaming machine information obtained for each gaming machine 20. By detecting this, it is possible to perform nail adjustment with very high accuracy.

C. Nail adjustment table generation processing:
FIG. 7 is a flowchart of the nail adjustment table generation process performed by the gaming machine information collection device 100 of this embodiment. This process is a process executed by the hall computer 130 from after the first day operation of the game hall to the start of the next day based on the game table information for each game table 20 illustrated in FIG. is there. Incidentally, what the nail adjustment table (sometimes called “nails”) is will be described in detail later.

  When the nail adjustment table generation process (step S200) is started, first, one game table 20 is selected from all the game tables 20 (step S202), and the current nail adjustment value of the selected game table 20 is selected. Is read (step S204). The nail adjustment of the game table 20 is performed based on a nail adjustment table described later, and the current nail adjustment value can be acquired by reading the nail adjustment table used at the previous nail adjustment.

  Subsequently, the gaming machine information for the selected gaming machine 20 is read (step S206). As described above, the gaming machine information obtained for each gaming machine 20 by the gaming machine information collection process of FIG. 4 is stored in the external storage device connected to the hall computer 130. Therefore, processing for reading the gaming machine information for the gaming machine 20 selected in step S202 from the gaming machine information stored in the external storage device is performed.

  Based on the gaming table information thus read, the average number of changes is calculated (step S208). The average number of fluctuations is obtained by dividing the number of symbol fluctuations included in the gaming machine information by the number of outs also included in the gaming machine information to obtain the number of symbol fluctuations per one out number. It can be calculated by converting to the value of.

  Following the average number of fluctuations, the average number of reserved balls is calculated (step S210). There are various calculation formulas for specific calculation formulas for the average number of reserved balls, but the average number of reserved balls to be obtained is roughly the following value regardless of which calculation formula is used. First, taking the time on the horizontal axis and the number of reserved balls on the vertical axis, and expressing how the number of reserved balls changes with time, the area under the line indicating the change in the number of reserved balls (in other words, Then, the area surrounded by the line indicating the change in the number of balls to be held and the horizontal axis is considered. This area can be considered to indicate the total number of reserved balls generated during the game. Next, consider a rectangle with operating time on the horizontal axis (the time when a player launches a game ball and playing a game), and the area of this rectangle is equal to the area corresponding to the total number of reserved balls. Thus, the height of the rectangle (value on the vertical axis) is determined. The average number of reserved balls can be considered as a value corresponding to the height of the rectangle (value on the vertical axis) thus determined. In addition, instead of taking the operating time on the horizontal axis, consider a rectangle that takes the operating time of the game hall (the time that is added to the time that the player is not playing games), the area of this rectangle, The height of the rectangle (value on the vertical axis) may be determined so as to be equal to the area corresponding to the total number of the reserved balls, and the height may be used as the average number of reserved balls.

  After calculating the average number of balls to be held, this time, the distribution of the holding time is calculated (step S212). As described above with reference to FIG. 6, the number of balls to be held can take five types of values “0”, “1”, “2”, “3”, and “4”. The duration is obtained every time. Therefore, the time ratio of the number of balls to be held 0 can be calculated by dividing the continuation time (holding 0 hours) when the number of balls held is 0 by the operating time of the gaming table 20 and further multiplying by 100. Similarly, for the number of reserved balls 1 to the number of reserved balls 4, the time ratio for each number of reserved balls can be calculated. By obtaining the time ratio for each number of balls to be held in this way, it is possible to obtain information (ie, the holding time distribution) as to what kind of holding state is occurring at what time ratio.

  In addition, although it demonstrated as what calculates the time ratio for every number of reserve balls here, it is not necessary to calculate the time ratio for every number of reserve balls. For example, the state of the number of balls held 0 and the state of the number of balls 1 held together, the time ratio of the number of balls held low is calculated, or the state of the number of balls 3 held and the state of the number 4 balls reserved In addition, the time ratio of the high-reserved ball count state may be calculated. Of course, the number of the reserved balls 1 to 3 or the number of the reserved balls 1 and 2 and the status of the reserved balls 2 and 3 are collected together. You may calculate the time ratio of a state. Depending on the type of the gaming machine 20 and the management policy of the gaming hall, there may be a case where it is not always necessary to distinguish the number of all the balls to be held and to grasp the time ratio. Therefore, in such a case, as described above, the processing time can be shortened by combining a plurality of states of the number of balls to be held, or the nail adjustment can be performed by devising a method for combining the plurality of states. It becomes possible to detect the required game table 20 more appropriately.

  As described above, after calculating the average number of fluctuations, the average number of reserved balls, and the distribution of the holding time for the selected gaming machine 20 (steps S202 to S212), it is determined whether or not the calculation is made for all the gaming machines 20. (Step S214). If there is a game table 20 that has not been calculated (step S214: no), the process returns to the top again to select one new game table 20 (step S202) and then the selected game. The following series of processes (steps S204 to S212) described above are performed on the table 20. When such operations are repeated and it is determined that the calculation has been performed for all the gaming machines 20 (step S214: yes), a process of comparing the average number of fluctuations and the average number of balls to be held with the respective reference values is started ( Step S216).

  Various values can be set as the reference value (first reference value) of the average number of fluctuations. In this embodiment, the average value of the same type of game machine 20 installed in the game hall is used. And Instead, use the average value of the same type of game machine 20 installed in the nearby game halls or game halls nationwide, or use the recommended value provided by the manufacturer of the game machine 20 Can do. Similarly, with respect to the reference value (second reference value) of the average number of reserved balls, in this embodiment, the average value of the game machines 20 of the same model installed in the game hall is used. Of course, an average value of the same type of game machines 20 installed in a nearby game hall or game halls nationwide, or a recommended value provided by a game machine manufacturer may be used. In step S216, for each gaming machine 20 from which the average number of fluctuations and the average number of balls on hold are obtained, the average number of fluctuations of that gaming machine 20 is compared with the first reference value, and the average number of balls on hold is set to the second reference value. Compare with In this way, when the average number of fluctuations and the average number of reserved balls are compared with the first reference value and the second reference value for each gaming machine 20, a nail adjustment table is output (step S218).

  FIG. 8 is an explanatory diagram illustrating a nail adjustment table. One nail adjustment table illustrated in FIG. 8 is generated for each game table 20. Of course, a single large nail adjustment table may be collected so that a plurality of gaming tables 20 can be listed. In the uppermost column of the nail adjustment table shown in FIG. 8, a table number for specifying the game table 20 is displayed. Below the table number, the table number is displayed for the past one week. Affects the determination of the necessity of nail adjustment, such as the number, the comparison result with the reference value (first reference value) of the number of average fluctuations, the comparison result with the reference value (second reference value) of the average number of balls Various data are displayed. For example, in the P001 gaming machine 20, the number of outs on Sunday, May 13, is 36,210, the average number of fluctuations on that day is lower than the first reference value, and the average number of balls to be held is second. It is displayed that it was lower than the reference value. Also, the number of outs on May 14 (Monday) was 36,180, the average number of fluctuations on that day was higher than the first reference value, and the average number of reserved balls was equal to the second reference value Is displayed. Although not displayed in the example shown in FIG. 8, other data such as a holding time distribution may be displayed on the nail adjustment table.

  Further, the nail adjustment table also displays data related to nail adjustment values. In the example shown in FIG. 8, the adjustment values of the nail are displayed for two places of the failure nail called “navel life nail” and the failure nail called “windmill twisting nail”. Of course, the obstacle nail for adjusting the nail is not limited to these two places, and the obstacle nail in other places may be adjusted. As described above, the nail adjustment table is a table in which various data used for determining whether or not nail adjustment is necessary is collected for each gaming machine 20.

  In the nail adjustment table generation process shown in FIG. 7, a nail adjustment table as described above is generated for each game machine 20 and printed on printing paper or output on a computer screen (step S218). The table generation process is terminated.

  As described above, in the nail adjustment table generation processing of the present embodiment, in addition to the number of outs for each gaming machine, the comparison result between the average number of fluctuations and the first reference value, and the average number of reserved balls and the second number The nail adjustment table is output in such a manner that the comparison result with the reference value can be compared in a list. For this reason, it becomes possible to perform nail adjustment appropriately and accurately even in a game hall in which a plurality of game tables 20 are installed. Hereinafter, this point will be described in detail.

  First, as described above, in the gaming table 20, whether or not the winning symbol is stopped and displayed on the symbol display device 22 and a special prize state is set is determined by the control computer mounted on the gaming table 20 by performing an internal lottery. Decide by doing. Therefore, it can be considered that as the number of symbol fluctuations increases, the number of special prizes also increases, and the safe number also increases. For this reason, the game stand 20 that has too many symbol variation counts per unit out number (average variation count) pays out game balls as prize balls more than the number of game balls fired by the player, and becomes deficit. It is considered that there is a high possibility.

  In addition, a player who plays a game on the gaming table 20 tends to dislike playing a game while the variable display is stopped on the symbol display device 22. Therefore, in the state where the hold ball is memorized, even if the current fluctuation display ends, the game is continued assuming that the fluctuation display will be resumed immediately using the hold ball, but there is no hold ball remaining Then, when the current variation display is over, it is considered that the game must be played with the variation display stopped, and there is a tendency to play the game with a somewhat unpleasant feeling. Therefore, the game stand 20 in which the number of balls to be held continues only with “0” or “1” is quickly bored by the player, so there is a high possibility that the number of outs will not increase. On the other hand, it is considered that the game stand 20 in which the reserved balls do not easily disappear is likely to increase the operating time and increase the number of outs in order for the player to continue playing with peace of mind.

  Furthermore, it is considered that the number of outs is different depending on the state of occurrence of the reserved balls even in the gaming machine 20 having the same average number of fluctuations. For example, there is a game table 20 that is barely displayed with fluctuations while it seems that there will always be no holding balls, and four holding balls are generated at once, and fluctuation display using the holding balls is performed, Comparing with the game stand 20 where the ball is generated again at the stage when the ball is almost gone, the former game stand 20 is playing while the player feels somewhat uneasy, In the latter game stand 20, the player can play the game with peace of mind. For this reason, the former gaming table 20 is quickly bored by the player, and the operating time and the number of outs do not increase, whereas the latter gaming table 20 is considered to increase both the operating time and the number of outs.

  In addition, the gaming table 20 where the number of reserved balls tends to increase tends to give the player an impression that the symbol display device 22 is frequently displayed more than the actual average number of times of variation. This is because it is rare for a player to play a game while counting the number of times the variable display is performed on the symbol display device 22, and when looking at the gaming machine 20 of the same model installed next to it. In addition, if the number of reserved balls on the own game table 20 is larger as a whole, it is often determined that the game table 20 has a high average number of fluctuations (so-called a table that rotates well). Of course, such a judgment cannot be made if the game is not being performed on the adjacent gaming table 20 or the model is different, but even in such a case, the player can be an approximate judgment criterion from his own experience. In many cases, the player has the number of balls on hold, and by comparing with the number of balls on hold, whether or not the current game table 20 is a game table 20 that rotates well is determined.

  In this way, the number of reserved balls is always displayed to the player while the player is playing a game, and thus has a great influence on the psychological state of the player. Moreover, the number of reserved balls does not directly change the safe number like the number of symbol fluctuations. For this reason, it is often possible to perform subtle nail adjustment by performing nail adjustment based on the number of reserved balls rather than performing nail adjustment based on the number of symbol fluctuations. That is, as described above, if the number of symbol fluctuations increases, the number of special prizes increases accordingly, and as a result, the number of safes increases. Thus, an increase in the number of symbol fluctuations directly leads to an increase in the safe number. On the other hand, in the case of the number of balls to be held, the increase in the number of balls to be held works in the direction of increasing the number of symbol fluctuations. It is not directly linked to an increase in the number of changes. As described above, this means that even if the number of symbols changes is the same, the number of balls that are held together reaches the upper limit, and the number of balls that are held at a constant frequency while always maintaining the number of balls held. It is clear from the fact that it can be assumed that this occurs. In other words, the average number of fluctuations tends to increase as the number of balls to be held increases, but depending on how the nail is adjusted, the average number of fluctuations is not increased so much (or the average number of fluctuations is maintained) and the number of balls is held. It is also possible to increase the number of balls. And since the number of reserved balls is always displayed to the player, even if the change in the number of held balls is a slight change, it is easy for the player to notice, and as a result, the player Thus, the psychological state that determines whether to continue or stop the game is greatly influenced. Therefore, when the average number of fluctuations is used as a reference, there are many cases where it is possible to adjust the nail appropriately by adjusting the nail based on the number of reserved balls even when the nail cannot be adjusted properly. Conceivable.

  As illustrated in FIG. 8, in the nail adjustment table of the present embodiment, the level at which the average variation number of the game table is compared with the reference value, and the level of the average number of reserved balls is compared with the reference value. Is output for each gaming machine in a manner that can be compared with the number of outs in a list. Therefore, by referring to such a nail adjustment table, it is possible to perform nail adjustment appropriately and accurately even in a game hall in which a plurality of game tables 20 are installed.

  In addition, since it is possible to simultaneously grasp the comparison result between the average number of fluctuations and the average number of balls to be held and the respective reference values, what kind of nail adjustment is performed for each gaming machine 20 by combining these. It is also possible to roughly grasp what should be done. Below, this point is demonstrated easily.

  FIG. 9 is an explanatory diagram showing the result of classifying the gaming table 20 using the average number of fluctuations and the average number of reserved balls. By combining the magnitude relationship between the average number of fluctuations and the first reference value and the magnitude relationship between the average number of fluctuations and the second reference value, as shown in the figure, the gaming table 20 is classified into four types. be able to. That is, "Class A" with a small average number of fluctuations but a large average number of reserved balls, "Class B" with a large number of average fluctuations and average number of reserved balls, and "Category C" with a small average number of fluctuations and average number of reserved balls. Then, each gaming table 20 can be classified into four types of “classification D” that has a large average number of fluctuations but a small average number of reserved balls.

  Among these, the “class A” gaming machine 20, that is, the gaming machine 20 in which the average number of fluctuations is determined to be lower than the reference value and the average number of reserved balls is higher than the reference value, is a so-called “well-operated table” for the player. On the other hand, for the game hall, the average number of fluctuations is low, so that it is a game table 20 that produces a profit with a small safe number. Therefore, it can be determined that the nail adjustment is unnecessary for the gaming table 20 of category A.

  In addition, the game table 20 of “Class B”, that is, the game table 20 that is determined that the average number of fluctuations and the average number of reserved balls are higher than the reference value is a nail adjustment that is advantageous to the player side, and is used as a game hall. It can be determined that the game table 20 should be tightened a little more.

  Furthermore, the “Category C” gaming table 20, that is, the gaming table 20 that has been determined that the average number of fluctuations and the average number of reserved balls are lower than the reference value, is a table that will soon get bored by the player and will not let the player escape. Therefore, it can be determined that the game table 20 should be loosened a little more.

  Furthermore, the gaming table 20 of “Class D”, that is, the gaming table 20 in which the average number of fluctuations is higher than the reference value and the average number of reserved balls is determined to be lower than the reference value is bored by the player because the number of reserved balls is small. Although it is easy to be placed, it is likely to become a special prize state, and only the number of safes is increased. Therefore, there is a high possibility that the game hall will be completely deficit, and it can be determined that the game table 20 is to be tightened with nails.

  In this way, by using the average number of fluctuations and the average number of reserved balls obtained for each gaming table 20, it is possible to easily detect the necessity of nail adjustment for each gaming table 20. In this embodiment, as shown in FIG. 8, a nail adjustment table including a comparison result between the average number of fluctuations and the first reference value and a comparison result between the average number of balls to be held and the second reference value is output. Therefore, on the game hall side, by referring to the output nail adjustment table, it is possible to immediately identify what kind of nail adjustment is necessary for each game table 20.

  In the above description, the operation of classifying the gaming table 20 using the comparison result between the average number of fluctuations and the first reference value, and the comparison result between the average number of reserved balls and the second reference value is a game hall. Explained that it was carried out in the human head, such as the management of. However, these classifications may be performed by the hall computer 130 and a nail adjustment table including the classification result may be output. FIG. 10 is an explanatory view exemplifying a nail adjustment table including a result of classifying the game table 20 by combining the average number of fluctuations and the average number of balls to be held.
