Description

  The present invention relates to a game data display device for gaming machines such as pachinko machines and slot machines.

  Conventionally, a technique for displaying game data of gaming machines in a graph is well known. For example, as shown in Patent Document 1, the graph range for displaying game data is changed according to the in-model maximum value and the in-model minimum value. This makes it possible to display a graph that is easy to see even if game data changes greatly. As another conventional example, for example, as shown in FIG. 7, there is a display in which a difference ball graph is displayed by dot display (the vertical axis indicates the difference ball, and the horizontal axis indicates the out).

JP 2002-119749 A

  However, in the graph display method disclosed in Patent Document 1, the transition of one game data can be grasped, but is a huge display area required when displaying data for a long period such as one week or ten days, for example? Alternatively, the graph display is reduced and the display becomes difficult to see. Further, since the display method shown in FIG. 7 requires a large display area and a large number of dots, it is necessary to display a fixed pattern such as an LED or a fluorescent display tube which is mainly used in the stand-alone information display device. It is too difficult to display the difference graph on the stand-by-table information display device provided in the gaming machine (notifying the player of the information on the difference in the difference), because it is too costly to increase the size or increase the number of dots. . Therefore, in order to display the difference graph on the table-specific information display device, there is only a means for using a liquid crystal screen. Needless to say, it is desirable for the game data to display information that the player (or manager of the game store) wants to obtain easily, but it is effective in a limited display area such as a stand-alone information display device. Could not display.

  The present invention has been made based on the above-described background, and an object thereof is to provide a game data display device that effectively displays necessary game data in a limited display area.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the game data display device of the present invention is a game data display device for displaying game data of a gaming machine in a graph,
An extraction means for extracting the maximum value and the minimum value for each fixed period of game data;
Display control means for displaying game data in a fixed period in a bar graph,
The bar graph is characterized in that the maximum value and the minimum value are both ends.

  In the game data display device of the present invention, game data obtained when operating for a certain period of time, for example, the maximum value and the minimum value of a difference ball are displayed at both ends of one bar graph. It is possible to display effectively in a limited display area. Further, when the predetermined period is, for example, one day, the maximum value and the minimum value of the difference balls over a period of 10 days or longer can be displayed side by side in a bar graph.

Specifically, the game data is a difference ball represented based on an out ball invested in a gaming machine and a safe ball paid out from the gaming machine,
The extraction means extracts the difference ball at the end of a certain period,
The display control means is characterized by displaying the time difference end ball extracted by the extraction means at a corresponding position in the length direction of the bar graph. Thereby, the difference ball which a player or a game store manager needs is displayed easily. Also, the difference ball at the end of business for a certain period (for example, one day) is displayed at the corresponding position of the length of the bar graph, and the end state of the difference ball that changes within one day is displayed in one bar graph It is also displayed efficiently.

  Further, specifically, the display control means is characterized by displaying a bar graph by dividing every predetermined period. As a result, when the fixed period is, for example, one day, even if the period is as long as 10 days, the maximum value of the difference ball (also referred to as the maximum difference), the minimum value (also referred to as the minimum difference), and the difference at the end of the fixed period The balls can be displayed side by side as a bar graph. Time series data such as past days of gaming machines can be arranged and displayed at a glance. Data can be displayed in a limited display area of the table-specific information display device provided in the gaming machine, and when the player views the display screen, data necessary for selecting the table can be known at a glance.

Furthermore, specifically, one scale (also referred to as a unit dot) of the bar graph is made of a light emitting member,
A bar graph is formed by stacking a plurality of unit dots in the length direction of a bar graph to form one bar graph,
The display control means is characterized in that one or a plurality of unit dots are blinked to display a difference ball at the end of a certain period or a specific state of the difference ball. Thereby, one of the unit dots forming the bar graph can be blinked to display a difference ball at the end of a certain period (for example, one business day). Further, it is possible to display that all the dots are blinked and that the difference ball is special (for example, data ranked in the best ten of the difference ball).

  Further, specifically, the display control means is characterized by displaying a bar graph in each gaming machine. Thereby, the bar graph which shows the maximum difference and the minimum difference of the difference ball of 1 business day, for example of each game machine can be displayed side by side. In addition, the end state of the difference ball at the end of one business day is displayed. It can be displayed on a monitor connected to the hall computer, and when the manager of the game store looks at the display screen, the state of the difference between individual game machines in the game store can be seen at a glance. For example, it is possible to provide easy-to-read information for machine adjustment of the table (adjustment of the balls).

  More specifically, the display control means is characterized in that it displays a bar graph divided into each set value of the gaming machine. Thereby, the relation between the set value set in the gaming machine and, for example, the difference ball can be understood at a glance. In this way, information required by the manager of the game store can be displayed in an easy-to-read manner.

(Example)
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall schematic diagram of the game data display system 100. The game data display system 100 includes a hall computer (game data display device) 1 and a plurality of slot machines 4 (1) to 4 (n) (4 (1) is the first machine, 4 (n) is the nth machine, and the like. Similarly, it may be represented by 4 below), the central information display device 6, the slot machines 4 (1) to 4 (n) and the hall computer 1, and further the central information display device 6 and the hall computer 1 And a communication network 10 connecting the two. On the communication path between the slot machine 4 and the hall computer 1, relay devices 2 (1) to 2 (n) (hereinafter sometimes represented by 2) and a stand-by information display device (game data display device) 3 ( 1) to 3 (n) (which may be represented by 3 below). Only one relay device 2 (1) to 2 (n) is provided for a plurality of slot machines 4 (1) to 4 (n), and data from each slot machine 4 is stored temporarily or continuously. Can be configured to manage.

  Next, FIG. 2 is a block diagram of the game data display system 100 of FIG. The hall computer 1 includes a CPU 101, a ROM 102, a RAM 103, an input / output interface 105 (I / O), and an HDD 104 (hard disk drive), which communicate with each other via a bus. A monitor 107 is connected via the input / output interface 105. The HDD 104 is allocated with a program storage area and a game data management area. In the game data management area, game data sent from the slot machine 4 is aggregated to create a database (data array). The CPU 101 of the hall computer 1 constitutes information output means for outputting the game data of the slot machine 4 together with the monitor 107.

  The relay device 2 includes a control unit 201 that includes a CPU 211, a ROM 212, a RAM 213, and an input / output interface 214. The table-specific information display device 3 includes a control unit 301 including a CPU 311, a ROM 312, a RAM 313, and an input / output interface 314, a display substrate 302, and a display unit 303. The display unit 303 of the table-specific information display device 3 displays data such as the number of bonuses and the number of games since the previous bonus. The central information display device 6 includes a control unit 601 including a CPU 611, ROM 612, RAM 613, and input / output interface 614, a display substrate 602, and a display unit 603, and can display data aggregated by the hall computer 1 on the display unit 603. It has become.

The slot machine 4 includes a control unit 401 including a CPU 411, a ROM 412, a RAM 413, and an input / output interface 414. The following signals are output from the external output terminals provided in the slot machine 4.
Out signal: Output safe signal according to the number of medals inserted: Output game signal according to the number of medals paid out: Output for each game execution Bonus signal: Output when bonus is awarded

The bonus and the set value can be explained as follows.
Bonus means that the payout rate is significantly increased. In addition, bonuses have a relatively long period of time in which the payout rate has increased for a relatively long time, and there are many BIG bonuses that can be obtained, and there are short periods of time in which the payout rate has increased compared to the BIG bonus. It is divided into few REG bonuses. Hereinafter, it may be simply referred to as BIG or REG.
The set value is a value for setting a probability of occurrence of a bonus in the slot machine, and the amusement shop changes this set value outside business hours. There are six setting values, for example, “1” to “6”. As the setting value increases from “1” to “6”, the probability that a BIG bonus or a REG bonus will occur increases. As a result, bonuses are more likely to occur and the payout rate is increased.

  The hall computer 1, the relay device 2, the stand-by information display device 3, and the slot machine 4 are connected to each other via communication networks 10 and 11. Game data generated by the operation of the slot machine 4 is sent to the hall computer 1 via the table-specific information display device 3 and the relay device 2. The hall computer 1 receives game data in order and at predetermined intervals for all the relay devices 2 (1) to 2 (n) installed in the game store. The hall computer 1 can collect game data output from the slot machine 4 for each of the slot machines 4 (1) to 4 (n).

  The CPU 311 (extraction means) of the table-specific information display device 3 has a maximum value (maximum difference), a minimum value (minimum difference) for each predetermined period of game data (for example, a difference ball (or difference medal)), and a predetermined period end. Has the function of extracting the difference ball. The CPU 311 (display control means) displays the maximum difference and the minimum difference of the difference balls extracted by the extraction means at both ends of the bar graph, and displays the difference ball at the end of a certain period at the corresponding position in the length direction of the bar graph. It has a function to do. Further, the CPU 311 (display control means) displays the maximum difference and the minimum difference of the difference balls and the difference ball at the end of the fixed period on a bar graph by dividing them at regular intervals (for example, the display unit 303 of the stand-by information display device 3 is also displayed). Display). The CPU 311 (display control means) has a function of blinking and displaying one or a plurality of unit dots D forming a bar graph. In the present embodiment, the stand-alone information display device side operates in a so-called stand-alone manner having functions of display control means and extraction means. That is, the stand-alone information display device 3 can be operated without a hall computer if only data can be obtained from the gaming machine. Of course, the CPU 101 can be configured to have a command function for controlling the display of the display unit 303 via the display substrate 302 of the stand-by information display device 3. That is, the display control means may be the CPU 311 or the CPU 101. Similarly, the extraction means may be the CPU 311 or the CPU 101.

  The CPU 101 (display control means) of the hall computer 1 displays the difference between the maximum difference and the minimum difference of the difference balls and the difference ball at the end of a certain period (for example, at the end of one business day) in a bar graph. Display on a monitor 107 connected to the computer 1. The CPU 101 can collect data from each gaming machine and display the difference ball as a bar graph for each gaming machine. The CPU 101 (display control means) has a function of displaying a bar graph by dividing each setting value of the gaming machine.

  FIG. 3 shows a display example of the display unit 303 of the table-specific information display device 3. FIG. 3A shows a 10-day difference trend graph. The display unit 303 includes a fluorescent display tube. In the display part 303, a bar graph display part 303a is formed at the center, and a display area of a bonus number display part 303b is formed at the bottom. In the bar graph display unit 303a, the vertical axis represents the difference ball and the horizontal axis represents the date. One scale (unit dot D made of a light emitting member) of the bar graph represents the difference ball 1000. Numbers “1” to “10” indicating dates are displayed side by side from the left to the right at the lower end of the bar graph display portion 303a (above the bonus count display portion 303b). The transition of the difference ball for the past 10 days is displayed. “Ima” on the left side of the date “1” represents a difference ball on the current day (current day).

  FIG. 4 shows a difference ball display graph in which a transition of the difference ball on a certain day is represented by a line graph. The above-mentioned 10-day difference ball transition graph is created from this difference ball display graph. In this embodiment, the difference ball (or difference medal) is defined as (safe)-(out). The maximum difference indicates the maximum value of the difference ball, and the minimum difference indicates the minimum value of the difference ball. In FIG. 4, the vertical axis represents the difference ball and the horizontal axis represents the out. FIG. 4 (a) shows the difference ball “one day ago” as a line graph 801. The difference ball starts from “0”, and the difference ball peaks in the minus direction at “−5000” and finally (when the store is closed). Represents “-4400”. As game data in this case, out is “11000”, safe is “6600”, difference ball is “−4400”, bonus is “5 times”, maximum difference is “0”, and minimum difference is “−5000”. In the data “1 day ago”, the maximum difference is not positive, and the difference ball is the maximum when it is “0”.

  A bar graph 701 indicated by the date “1” in FIG. 3A represents the difference ball “one day ago” as a bar graph. The maximum difference and the minimum difference are represented by the length of the bar (the number of unit dots D stacked in the length direction). Since the maximum difference one day ago is “0” and the minimum difference is “−5000”, 5 dots are displayed on the “−” side from the central “0” axis. That is, the uppermost part of 5 dots indicates the maximum difference, and the lowermost part indicates the minimum difference. And the difference ball at the time of closing is made to be able to be identified by blinking display. Since the difference ball at the time of closing the store “1 day ago” is “−4400”, the dot located at the bottom of the 5 dots corresponding to “−4400” is displayed blinking. A control signal is input to the display substrate 302 from the CPU 311 of the table-specific information display device 3 to control the display on the display unit 303. The dot display color (or pattern) is color-coded into three colors. That is, the “−” side has one color, and the “+” side has two colors (1 to 5 dots on the “+” side, a color different from 6 dots or more).

  Next, FIG. 4B shows the difference ball “2 days ago” as a line graph 802, starting from the difference ball “0”, the difference ball peaking at “2300” in the plus direction, and thereafter “ "-3600" indicates that the peak is finished at "-2000" when the store is closed. As game data, Out is “11600”, Safe is “9600”, Difference is “−2000”, Bonus is “8 times”, Maximum difference is “2300”, and Minimum difference is “−3600”. The bar graph 702 indicated by the date “2” in FIG. 3A represents the difference ball “2 days ago” as a bar graph.

  Similarly, FIG. 4 (c) shows “3 days ago”, FIG. 4 (d) shows “4 days ago”, FIG. 4 (e) shows “5 days ago”, and the date “3” in FIG. “4”, “5”, and bar graphs 703 to 705. In the case of “5 days ago”, in “5” in FIG. 3A, the maximum difference is the scale full scale, which represents “+10000 or more”. Hereinafter, in this way, the difference ball transition of the past 10 days can be displayed side by side as shown in FIG. The difference data for the past 10 days are displayed in a compressed form and can be seen at a glance. Note that the graph of FIG. 4 is an image and is not necessarily created. If the maximum value and minimum value for each predetermined time and the value at the end of the predetermined time can be collected, the data display as shown in FIG. It is possible to do.

  In the bonus number display section 303b in the lower part of FIG. 3A, the number of bonuses is displayed corresponding to each date. In FIG. 3A, “5” is displayed below the date “1” (“one day ago”), and “8” is displayed below “2” (two days ago).

  Next, FIG.3 (b) shows a 10-hour difference ball transition graph. The vertical axis represents the difference ball, and the horizontal axis represents time. The maximum difference and the minimum difference for every hour and the final appearance in one hour unit can be expressed by a bar graph. In FIG. 3B, “1” represents “1 hour ago”, “2” represents “2 hours ago”, and “10” represents the maximum difference and the minimum difference of “10 hours ago”. Then, the last game in an hour unit is displayed in a blinking manner. For example, the dot located at the bottom of the 5 dots on the plus side of “5” (“5 hours ago” bar graph 715) is blinked. With regard to the timing of the passage of time, it can be updated at a timing of 00 minutes per hour (that is, in units of 1 hour if the store opens at 9:00), or can be updated at a predetermined number of outs (for example, 1800 corresponding to 600 games). . In this manner, the difference ball transitions of the past 10 hours can be displayed side by side as bar graphs. Also, the number of bonuses per hour is displayed in the bonus number display part 303b in the lower part. In addition, the difference ball at the time of closing can be displayed separately, for example, by changing the blinking speed. Further, the 10-day difference ball transition graph and the 10-hour difference ball transition graph can be switched and displayed by a button operation.

  Next, FIG. 5 shows a modification. The example of a display of the monitor 107 connected to the hall computer 1 is shown. This is a bar graph showing the difference of one business day for each vehicle in a model installed in an amusement store. In FIG. 5, the vertical axis represents the difference ball, and the horizontal axis represents the table number. The length of the bar graph represents the maximum difference and the minimum difference, and the star mark represents the difference when the store is closed. At the lower end of the bar graph display portion 107a, numbers “1” to “15” indicating the table numbers are displayed side by side from left to right. A display area of a set value display unit 107b for displaying set values including six stages (“1” to “6”) for adjusting the payout rate of the slot machine is formed below the bar graph display unit 107a. A set value is input for each game machine and is associated with a date and a machine number. A maximum difference, a minimum difference, and a difference ball at the time of closing are extracted in advance for each table, and displayed based on this. The display on the monitor 107 is controlled by a control signal from the CPU 101. In FIG. 5, the set number “1” is set to “6”, a bar graph 901 is displayed longer on the “+” side than the central “0” axis, and shorter on the “−” side. Is shown at the top. Bar charts showing the difference balls can be displayed side by side, and the difference balls for each table can be seen at a glance. The relationship with the set value can also be grasped.

  Next, FIG. 6 shows another example of the display example of the monitor 107. The average of the difference balls for each set value of a certain model in a certain period is shown by a bar graph. The vertical axis represents the difference ball, and the horizontal axis represents the set value. At the lower end of the bar graph display portion 107a, numbers “1” to “6” indicating set values are displayed side by side from left to right. Data is calculated in advance by averaging the maximum difference, the minimum difference, and the difference ball at the time of closing of the vehicles divided by the set value for a plurality of periods. Based on this, the average for each set value can be represented by the length of the bar graphs 921 to 926. Moreover, the average of the difference ball at the time of closing a store can be represented by a star. It can be arranged for each set value, and the relationship between the set value and the difference ball can be grasped. In place of the average, the best difference, the maximum difference, and the closing time difference ball best 1 (maximum, minimum and closing time difference ball) are extracted, and the bar graph length and star are indicated for each set value. May be.

  In this way, the maximum difference and the minimum difference of the difference balls obtained when the slot machine 4 is operated for one day or one hour are displayed at both ends (the number of stacked unit dots D) of one bar graph. It is possible to display effectively in a limited display area. In addition, the difference position at the end of the day is flashing the corresponding position (corresponding dot) of the length of the bar graph, and the end state of the difference ball that changes within one day is matched to one bar graph. Display efficiently. The difference ball required by the player or the store manager is displayed in an easy-to-see manner.

  Even in a long period such as 10 days, bar graphs showing the maximum difference, the minimum difference, and the difference at the end of one business day can be displayed side by side. Time series data such as past days of gaming machines can be arranged and displayed at a glance. Data can also be displayed in a limited display area of the table-specific information display device 3 provided in the gaming machine. When the player views the display unit 303, the data necessary for table selection can be known at a glance.

  Further, a bar graph indicating the maximum difference and the minimum difference of the difference balls of individual gaming machines on one business day can be displayed side by side. In addition, the end state of the difference ball at the end of one business day is displayed. The manager of the game store can display the information on the monitor 107 connected to the hall computer 1, and when the manager of the game store looks at the monitor 107, the state of the difference between individual game machines in the game store can be seen at a glance. For example, it is possible to provide easy-to-read information for machine adjustment (change of setting value) of the table.

The bar graph in the embodiment described above can be modified as follows.
(1) You may make it blink the dot which generate | occur | produced later among the maximum difference and the minimum difference. If the maximum difference occurs later, it can be recognized that the vehicle is in a positive tendency. In that case, the blinking speed may be changed in order to distinguish it from the display of the difference ball at the time of closing. For example, when the maximum difference of “5 days ago” in FIG. 3A occurs later, the top dot of 11 dots blinks (a speed different from the third dot from the top showing the difference ball at the time of closing) Blinking). In addition to the blinking speed, for example, the display color may be changed to distinguish the display.
(2) When the maximum difference or the minimum difference is ranked in the best ten of the difference within a predetermined period (for example, from the time the model is changed to the same day), all the dots on the graph may be blinked. For example, when the maximum difference of “5 days ago” in FIG. 3A is ranked in the best ten, 11 dots (all dots from −1000 to +10000) are blinked. In that case, in order to implement the example of (1) above, it is possible to alternately flash or change the flashing speed in order to distinguish the difference between the closing time and the maximum difference (or minimum difference) that occurred later. That's fine. In addition to the blinking speed, for example, the display color may be changed to distinguish the display.
(3) Although the bar graph display displays the difference ball at the end of a certain period on the bar graph with the maximum and minimum values of the difference ball as both ends, of course, only the bar graph with the maximum and minimum values of the difference ball as both ends is displayed. It is good also as a structure which displays and does not display the difference ball at the end of a fixed period.

Moreover, the following modifications are possible for the range of the bar graph in the embodiment.
(4) The range width of “+” and “−” of the bar graph may be changed. For example, “+” is 500 pieces per division, and “−” is 2000 pieces per division, and the effect of displaying as many are possible.
(5) The range of the horizontal axis of the bar graph does not have to be in units of one day or one hour. For example, a line feed may be made every 2 hours or every predetermined number of outs.
(6) The horizontal axis that is “0” may not be arranged in the middle of the vertical axis. For example, the horizontal axis may be arranged slightly below, the “+” scale may be increased, and the “−” scale may be decreased.

Furthermore, the following modifications can be made to the history.
(7) A history may not be left depending on whether the difference ball reaches a set value or an average value. For example, when the maximum difference is not “+” or the minimum difference exceeds 10,000 sheets, no history is recorded. In the example of FIG. 3A, “1 day ago” and “3 days ago” are applicable, and updating is performed without leaving a history. If the minimum difference (minus the difference) is large, there is a risk that the image at the amusement store will be destroyed, but this will have the effect of not destroying that image.
(8) If a predetermined out is not reached, no history may be left. For example, when there is no 200 outs per hour, when there are no 2000 outs per day, no history is recorded. In this case, it may be recorded as data only by not displaying, or may not be recorded. There are many cases in which the game data itself is insufficient and cannot be used as a reference if it does not reach the predetermined out, but in this way, the purpose of the present application to display only valid data within a limited space Come true.
(9) In the case of (7) and (8) above, the previous date or time mark may be blinked to inform the player that no history has been left. Originally, a data display device is provided to display accurate data, but the inclusion of data that is not displayed is inaccurate and contrary to its original meaning, which may lead to anxiety of the player. In this way, the anxiety can be removed, and if there is no notification, the player can be informed that the data is correctly displayed.

In addition, the following modifications are possible.
(10) In the present embodiment, the bar graph of the difference of one business day for each vehicle shown in FIG. 5 is displayed on the monitor 107, but the present invention is not limited to this. For example, you may make it display all or one part of the bar graph according to a table on the display part 303 of the table information display apparatus 3 similarly. It can be displayed by switching buttons. The player can obtain information on other machines on the gaming machine side and can use it as a reference for selecting machines. In this case, the set value information may or may not be displayed.
(11) In the embodiment shown in FIG. 5, the information is displayed every business day. However, the present invention is not limited to this, and it is divided every predetermined time (for example, every 3 hours, morning, afternoon, evening, before closing, etc.). It may be displayed. Further, game data for a plurality of days may be displayed without being associated with the set value.
(12) The difference ball transition graph shown in FIG. 3 may be diverted and displayed on the monitor 107 connected to the hall computer 1 or the display unit 603 of the centralized information terminal device 6. Further, the display unit 303 of the table-specific information display device 3 may be displayed with liquid crystal.
(13) Instead of the bonus display simultaneously displayed on the display screen, the AT count (assist time count), the total start count, and the total out count may be indexed and displayed. For example, a total out number of 20000 or more can be expressed as “A”, 15000 or more and less than 20000 can be expressed as “B”, and 10,000 or more and less than 15000 can be expressed as “C”.
(14) Although the example applied to the slot machine has been described in the present embodiment, it can also be applied to a pachinko machine. When applied to a pachinko machine, the bonus can be replaced with a jackpot.
