Description

  The present invention relates to a notification method in a gaming machine in which the probability of drawing whether or not to execute a special game that is advantageous to the player varies between a normal probability and a high probability.

Conventional pachinko machines have a normal probability state where the probability of hitting is a normal probability and a high probability state where the probability of hitting is a high probability, so that the current state can be easily understood by the player and the store clerk of the game store. Different notifications of video, sound, light, etc.
Moreover, in patent document 1, there exist some which provided multiple types of high-probability states, and differed the alerting | reporting method for each of the multiple high-probability states.
Also, with conventional pachinko machines, a power outage or the like occurs during the game, and even if the power of the pachinko machine is cut off, the probable probability state or winning a prize will be cut off so as not to give a disadvantage to the player It is configured to back up the payout status of prize balls to be paid out when a game ball wins in the mouth.

  Recently, there have been many cases in which a player replaces a normal ROM programmed with game control with an illegal ROM modified so as to make a big hit more easily than a normal one, and causes great damage to the game store.

  Normally, a normal ROM is set to start from a normal probability state when the power is turned on, but an illegal ROM is often set to start from a high probability state when the power is turned on. .

  On the other hand, there is a case in which an amusement store holds an event to attract a large number of players, and at that event, the amusement store replaces the regular ROM with an illegal ROM. Replacing a regular ROM with something that is not a legitimate ROM is illegal in itself, but if you try to replace it with a fraudulent ROM that has been modified so that it is easier to win than a regular one, there is no damage to the player. . However, if a game store also uses a ROM that is easier to hit than a regular one every day, it will not be profitable, so after a few days, it will be replaced with a regular ROM or a ROM that is harder to hit than a regular one. As a player, it will be a big win at the event, so I thought that this store could win, and even if it was replaced with a ROM that is hard to hit than the regular one, I will play only in that store without noticing Eventually, the player will suffer significant damage.

JP 2000-224353 A

As described in the background art, in a conventional gaming machine, the notification method is different between the normal probability state and the high probability state, so that the store clerk of the game store can easily determine whether the game table is in the normal probability state or high probability. Although it is possible to determine whether the game table is in a state, it is not possible to determine whether the ROM in which the game control is programmed is an authorized ROM or is replaced with an illegally modified ROM.
Similarly, it is impossible for a player to determine whether a regular ROM or a modified ROM is attached.
The fact that it is impossible to determine whether a legitimate ROM is attached to a pachinko machine or whether a modified ROM is attached to a pachinko machine, has been noticed for a long time even if an illegally modified ROM is attached to a pachinko machine. Without a loss, the amusement shop or the player will suffer a great deal of damage.

  Also, in recent pachinko machines, the same notification in the normal probability state and the high probability state, or a notification that is slightly changed, is set so that after the high probability state, the high probability state will continue until A pachinko gaming machine has been devised that has improved its taste by setting whether it is difficult for the player to understand. With such a configuration, pachinko gaming machines become more attractive, but on the other hand, there arises a problem that fraud becomes difficult to find.

  The present invention has been devised in order to minimize damage to a game store or a player by making a configuration in which fraud is easily detected even if the fraud is performed as described above. is there.

  In order to solve the above-described problem, the gaming machine according to claim 1 is in a state advantageous to a player by an extraction value extracted due to detection of a game ball by a starting means provided in the game area. A special game lottery means for lottering whether or not to execute a special game, and the special game when a predetermined condition is satisfied in a normal probability state in which the lottery probability of whether or not to execute the special game is a normal probability. A probability changing means for changing to a high probability state in which a lottery probability of whether or not to execute is stored, and a game state immediately before the power is turned off when the power is turned off, and a game immediately before the power is turned off after the power is restored And a backup means for allowing a game to be resumed from a state, based on the storage of the backup means when a predetermined condition is satisfied in a normal probability state and a high probability state is established, and after power is restored. A gaming machine is characterized in that set so that different notification pattern informing means in the high probability state in the case where in a high probability state.

  As a specific example of the “starting means” here, a random number is extracted when a fired game ball is detected, and a start port from which a prize ball is paid out. A gate or the like is generally used, and it is generally determined that the extracted random number value is lost, and the player is notified of the appropriate loss according to the design.

  The term “advantageous to the player” as used herein refers to a prize that is released when it is easy to enter a prize opening where a game ball does not enter or is difficult to enter in a normal period of time, or when the extracted random number is a win. The opening time of the mouth is opened for a long time, the fluctuation time of the symbol for notifying the player of the loss is shortened, and the probability of winning is higher than in the normal state.

  Further, the “special game lottery means” is for determining whether or not the random number value extracted when the game ball passes through the start port or the start gate matches a predetermined value. The result is notified to the player by a symbol or the like.

The “predetermined condition” here refers to the case where the random number value extracted when a game ball is detected at the starting port or the starting gate matches the predetermined value, or the extracted random number value is determined in advance. The big hit game (a state that is advantageous to the player) that is started when the symbol that matches the displayed value is confirmed and displayed or when the extracted random number value matches the predetermined value ends. After.
Conventionally, in a general gaming machine, when a random number value extracted when a game ball wins a start opening is a predetermined value (that is, a winning value) for a big hit game, After the symbol for informing that the game has been finalized, the jackpot game is played, and after the jackpot game is finished, a high-spec model that is in a high probability state and the game ball is played when the game ball wins the start opening. In addition to the random number value that determines whether or not a high probability state is extracted, the random value that determines whether or not to enter the high probability state is also extracted. If the random value that determines whether or not to make a probability state matches the predetermined high probability state value, a jackpot game is performed after the symbol for informing that it is a win is displayed, After the jackpot game is over, It is generally half-spec type the saying goes.

  The backup means is a means for storing the game state immediately before the power cut-off even when the power of the pachinko gaming machine is cut off, and allowing the game to resume from the game state immediately before the power cut-off after the power is restored. In other words, the backup power supply for holding the memory when the power is shut off and the program so that the game state can be resumed immediately after the power is restored. Of course, the game state stored in the backup means is a normal probability state, a high probability state, or a big hit state (a state advantageous to the player). It is preferable to back up various things such as the payout status of prize balls to be paid out, the position of movable objects (motors, solenoids), and the extracted random numbers and numbers.

“Make the notification pattern different” here is different from the case where a predetermined condition is established in the normal probability state and the high probability state is established, and the case where the high probability state is established based on the storage of the backup means after the power is restored. Needless to say, special notification is not performed when a predetermined condition is established in the normal probability state and the high probability state is established, and only when the high probability state is established based on the storage of the backup means after the power is restored. Notification is also included. Not performing special notification means that notification is performed with the same notification pattern as the notification pattern in the normal probability state even in the high probability state.
Examples of the notification means include lamps provided on a board surface or a gaming machine frame, a speaker, a symbol display device for displaying a symbol used to notify the player whether or not it is a hit.
In addition, when the high probability state is entered based on the storage of the backup means after the power is restored, the high probability state follows a different notification pattern from the case where the predetermined condition is established and the high probability state is established in the normal probability state. It is desirable to keep reporting as long as possible. By continuing to notify different notification patterns as long as the high probability state continues, the possibility that a store clerk or player notices increases, leading to early detection of fraud.

  When performing notifications using LEDs or lamps, it is conceivable that the notification pattern may differ depending on the brightness level, the timing of turning on and off, the difference in emission color, etc., and the notification is performed by sound using a speaker It may be possible to change the notification pattern depending on the pitch of the sound, the tempo, the song, etc., and when the notification is performed by display, the notification is based on the difference in the background and design colors and the display content (character, etc.). Different patterns can be considered. Moreover, when performing notification by display, one may display “high probability state” and the other may display “high probability state (power failure recovery)”.

It should be noted that the symbol for notifying the player of whether it is a hit or a loss is generally a three-digit number, and is frequently changed at a high speed, and then the symbol is stopped one digit at a time. In the case of winning, the same three-digit number such as “777” is used, and in the case of a loss, the three-digit number such as “123” and “776” is not matched. However, the present invention is not limited to this, and the pattern may be a single digit, or may be a pattern or a kanji character instead of a number. Also, there are various expressions for winning or losing, such as winning when a character defeats a villain or winning when a character finds a treasure.
A CRT, a liquid crystal display device, an EL display device, a dot matrix display device, a 7-segment display device, or the like is used as a symbol display device that displays a symbol.

  According to a second aspect of the present invention, in the gaming machine according to the first aspect of the present invention, the game machine has a main control device having the special game lottery means and a plurality of sub-control devices controlled by instructions from the main control device. The backup means is provided in the main control device, and at least one sub-control device among the plurality of sub-control devices has a high-probability state when the gaming state immediately before power-off is a high-probability state. A gaming machine characterized in that a gaming state storage means is provided for storing information on what happened.

Examples of what can be considered as “a plurality of sub-control devices” here include, for example, a symbol control device that controls a symbol display device, a payout control device that controls payout of prize balls, a sound control device that controls sound, a lamp A lamp control device that controls LEDs and a power supply device that controls supply of power can be considered. Further, the game state storage means is not provided in only one sub-control device, but the game state storage means may be provided in a plurality of sub-control devices. Further, backup means may be provided in the sub-control device.
The game state storage means stores and holds the game state immediately before the power cut-off even when the power is cut off, but unlike the backup means, the game state storage means does not resume the game from the game state immediately before the power cut-off after the power is restored.

  According to a third aspect of the present invention, in the gaming machine according to the second aspect, the informing means is controlled by the sub control device provided with the gaming state storage means, and is provided in the sub control device when power is restored. In addition, when the storage content of the gaming state storage means is a memory indicating that the gaming state immediately before power-off is a high probability state, the sub-control unit can receive the command without receiving a command from the main control unit. The gaming machine is characterized in that a notification pattern different from a case where a predetermined condition is satisfied in a normal probability state and a high probability state is set is notified by the notification means.

  Here, “the sub-control device notifies the notification means of a notification pattern different from the case where the predetermined condition is satisfied and the high-probability state is established in the normal probability state without receiving a command from the main control device.” For example, after the power supply is restored, the main control device is set to output a command for informing the state (big hit probability state) to the sub-control device that controls the notification means. If a command to notify the state from the main control device after the return is not input even after a predetermined period of time, by setting to notify independently based on the gaming state storage means, Even if there is a command for notifying the state from the main control device to the sub-control device that controls the notification means, the sub-control device confirms the contents stored in the game state storage means, If the stored content is a memory indicating that the state immediately before the power-off was in a high probability state, a notification that is different from the case in which the predetermined condition is satisfied in the normal probability state and the state becomes a high probability state is performed. . In addition, after the power supply is restored from the beginning, the main controller may not output a command for informing the sub controller of the state.

  Immediately after the power is restored, the sub-control device is configured to control independently even if there is no command from the main control device. However, in order to synchronize with the main control device and other sub-control devices, the main control is normally used. It is desirable to control only when a command from the device or another sub-control device is received.

  Note that “control the notification means by the sub control device provided with the game state storage means” means, for example, that a sub control device that actually controls the notification means and a sub control device provided with the game state storage means are provided. It is also included that the sub-control device provided with the game state storage means issues a command to the sub-control device that actually controls the notification means and makes the notification means perform the notification.

  According to a fourth aspect of the present invention, in the gaming machine according to any one of the second to third aspects, the stored contents of the backup means provided in the main control unit and the game state storage provided in the sub control unit when power is restored. If the storage content is different from the storage content of the means, the high probability state based on the storage of the backup means when the predetermined condition is satisfied and the high probability state is established in the normal probability state Is a game machine characterized in that the notification pattern of the notification means is set to be different.

  Here, “notify the notification pattern” means that the predetermined condition is established in the normal probability state and the high probability state is established, and the case where the high probability state is established based on the storage of the backup means after the power is restored. If the patterns are different, and further the contents indicate that the stored contents of the backup means and the stored contents of the gaming state storage means are different, notification different from the above two notification patterns is performed. At this time, the notification pattern in the normal probability state may be the same as or similar to the notification pattern in the normal probability state when the predetermined condition is satisfied in the normal probability state.

  The relationship between the main control unit and the sub control unit is preferably one-way communication in which only a command is sent from the main control unit to the sub control unit, but is stored in the backup means of the main control unit as described in claim 4 When the content is compared with the content stored in the game state storage means of the sub-control device, a bidirectional communication configuration in which the main control device and the sub-control device can transmit and receive each other is suitable.

  According to a fifth aspect of the present invention, in the gaming machine according to any of the second to fourth aspects, the stored content of the backup unit and the stored content of the gaming state storage unit can be cleared when power is restored, and the main control is performed. The clearing method for clearing the stored content of the backup means provided in the device and the clearing method for clearing the stored content of the gaming state storage means provided in the sub-control device are set differently. It is a gaming machine characterized by this.

  Here, “the clearing method when clearing the stored contents of the backup means and the clearing method when clearing the stored contents of the gaming state storage means” means, for example, a clear switch for clearing the stored contents of the backup means A clear switch for clearing the storage contents of the game state storage means may be provided, respectively, and the clear switch is common, an effective period during which the storage contents of the backup means can be cleared, and an effective period for clearing the storage contents of the gaming state storage means The period may be different. In addition to the clear switch, there is a changeover switch that switches between clearing the stored contents of the backup means or clearing the stored contents of the gaming state storage means, or pressing the clear switch while pressing the power switch will change the stored contents of the backup means. A configuration may be adopted in which the contents stored in the gaming state storage means are cleared when the clear switch is pressed without pressing the power switch. Moreover, the reverse may be sufficient.

When providing a clear switch, the structure provided in the back surface of the pachinko game machine is preferable so that a player cannot operate easily. Further, the clear switch may be surrounded by a case so that the case is locked.
In addition, it is preferable to provide a notification lamp that indicates that the backup means and the game state storage means have been stored, or that the stored contents of the backup means and the game state storage means have been cleared. In this case, the notification lamp is different for the backup means and the game state storage means.

According to the first aspect of the present invention, the notification in the high probability state when the predetermined condition is established in the normal probability state and the high probability state is obtained and when the high probability state is established based on the storage of the backup means after the power is restored. By making the notification patterns of the means different, it becomes possible for the store clerk or the player to easily determine the process through which the high probability state has been reached even in the same high probability state, thereby enabling early detection of fraud.
Normally, power outages do not occur frequently, so it can be said that there is not much that will happen suddenly when the power is turned on. In other words, if the notification is not a notification pattern in the normal probability state but a notification pattern that is not a notification pattern in the high probability state when the predetermined condition is satisfied in the normal probability state and becomes a high probability state, Can immediately notice, and if it is confirmed whether or not there is a power outage and the power of the pachinko machine is cut off by another store clerk, it is possible to roughly determine whether or not the ROM has been replaced. If there is a possibility that the ROM has been replaced with an illegal ROM, an accurate judgment can be made by confirming the gaming machine.
Many pachinko machines are installed in pachinko machines, and the daily business hours are about 14 hours. All of the pachinko machines have regular ROMs or illegal ROMs. It takes a lot of effort to confirm. In addition, there are 14 hours when a regular ROM is replaced with an illegal ROM. That is, it is necessary to check whether or not a regular ROM is frequently attached. However, in many actual game stores, it is almost impossible to check all the gaming machines frequently, so they are checked after closing. Checking after the store is closed will cause a great deal of damage to the amusement store if an illegal ROM is attached. However, if the present invention is used, a notification pattern that is not a notification pattern in a normal probability state but a notification pattern that is not a notification pattern in a high probability state when a predetermined condition is established and a high probability state is established in the normal probability state. In such a case, it is only necessary to examine only the game machine, so that it is possible to detect fraud early without having a great deal of effort.

  In addition, when the high probability state is entered based on the storage of the backup means after the power is restored, the high probability state follows a different notification pattern from the case where the predetermined condition is established and the high probability state is established in the normal probability state. It is desirable to keep reporting as long as possible. By continuing to notify different notification patterns as long as the high probability state continues, the possibility that a store clerk or player notices increases, leading to early detection of fraud.

  According to the second aspect of the present invention, in the case where the state immediately before the power shutoff is in a high probability state separately from the backup means provided in the main control device, the game state storage means for storing information indicating that is sub By providing the control means, it is possible to reduce the processing burden on the main control device that controls the entire gaming machine. Even if the game state storage means is not provided in the main control device or the game state storage means itself, a high probability is established based on the storage of the backup means when the predetermined condition is established in the normal probability state and a high probability state is established and after the power is restored. It is possible to change the notification pattern depending on the situation, but with such a configuration, the regular ROM will be in a high probability state when the power is turned on, and the notification in the high probability state will be in the normal probability state. If the ROM is replaced with an illegal ROM that is set to perform a notification pattern when a predetermined condition is established and a high probability state is established, illegal early detection becomes impossible. However, by providing the game state storage means in the sub-control device instead of the main control device that controls the big hit probability as described in claim 2, even when the illegal ROM is replaced as described above, the illegality is accelerated. Be able to discover. If the game state storage means provided in the sub-control device as well as the ROM provided in the main control device is replaced with an illegal one, it becomes impossible to detect fraud early, but it is provided in the main control device. Since it takes a lot of time to change both the ROM and the gaming state storage means provided in the sub-control device to an illegal one, there is a high possibility of giving up on the way. In other words, fraud is suppressed.

  According to the invention of claim 3, when the storage content of the game state storage means provided in the sub-control device after the power return is a storage indicating that the state immediately before the power supply is off is a high probability state, Even if there is no command from the control device, the sub-control device makes its own notification by changing the notification pattern of the notification means different from the case where the predetermined condition is established in the normal probability state and the high probability state is entered. The normal ROM provided in the main control device is in a high probability state when the power is turned on, and the notification pattern when the predetermined condition is established in the normal probability state and the notification in the high probability state is established. Even if the ROM is replaced with an unauthorized ROM that is set not to issue a command to notify the sub-control device that controls the notification means, the unauthorized early detection becomes possible.

  According to the fourth aspect of the present invention, when the storage content of the backup means and the storage content of the gaming state storage means are different after the power is restored, the predetermined condition is satisfied in the normal probability state. In this case, the notification is made with a different notification pattern from that in the case of the high probability state and the case of the high probability state based on the storage of the backup means after the power supply is restored. The fact that the stored contents of the backup means and the stored contents of the game state storage means are different after the power is restored means that the ROM provided in the main control device can be replaced with an illegal ROM. In such a case, the notification is made with a notification pattern that is not normally used. In this case, the store clerk can immediately notice and detect fraud early.

  According to the invention of claim 5, the control is simplified by making the clearing method for clearing the stored contents of the backup means different from the clearing method for clearing the stored contents of the gaming state storage means. The The backup means is provided in order not to give a disadvantage to the player even in the event of a power failure, etc., and the game state storage means is provided in order to enable early detection of fraud. In addition, when the stored contents of the backup means must be cleared, when a game machine is handed over from the manufacturer to the hall, when an error occurs, the game machine is not in a normal state even when the store is closed. The only time when the stored contents of the game state storage means must be cleared is when the game machine is handed over from the manufacturer to the hall. In this way, it is wasteful to perform a process that does not need to be configured to simultaneously clear memories that have different purposes and timings. However, the control can be simplified by setting different clear methods. .

  For example, the storage contents of the backup means and the storage contents of the gaming state storage means can be cleared at the will of the store clerk, and a clear switch is provided on the back of the gaming machine so that it is not easily operated by the player. The clear switch for clearing the stored content is preferably surrounded by a cover with a key or the like. If the stored contents of the gaming state storage means provided so that fraud can be detected at an early stage is cleared by the player, there is a possibility that fraud can not be detected early, but as described above, the gaming state storage means By making it impossible to easily operate the clear switch for clearing the stored contents, it is possible to prevent unauthorized early detection. Surrounding the storage contents of the game state storage means with a case with a key takes time and effort even when the store clerk clears it, but as described above, there is very little to clear the storage contents of the game state storage means. No problem.

  Next, the best mode of the present invention will be described with reference to examples. Needless to say, the present invention is not limited to the examples described in the following examples, and can be implemented in various forms without departing from the gist of the present invention.

As shown in FIG. 1, a pachinko machine 50 which is a kind of a ball game machine has a structure in which each part of the configuration is held by a casing composed of a rectangular outer frame 51 and a front frame 52.
The front frame 52 is attached to the outer frame 51 so as to be openable and closable by hinges 53 on the left and right, and is normally in a closed state as shown in the figure.
A window-shaped glass frame 60 is attached to the front frame 52 so as to be openable with respect to the front frame 52. A plate glass 61 is double-fitted into the glass frame 60, and the game board 10 (see FIG. 2) held by the front frame 52 is stored in the back of the plate glass 61.
An upper plate 55 is attached to the lower side of the glass frame 60 so as to be openable to the front frame 52. A lower plate 63 is fixed to the front frame 52 below the upper plate 55, and is fired on the right side of the lower plate 63. A handle 64 is attached. When the firing handle 64 is turned clockwise, a launching device (not shown) is activated to launch the game ball supplied from the upper plate 55 toward the game board 10.
The pachinko machine 50 is a so-called CR machine and includes a prepaid card unit (CR unit) 52 for reading and writing a prepaid card. The pachinko machine 50 includes a lending button 55 and a checkout button 56. And a CR settlement display device having a balance display 57.
Further, the front frame 52 has a plurality of frame-side decorative lamps 65 (corresponding to notification means) and speakers 51 (corresponding to notification means) for increasing the player's taste and informing the player and store clerk of the gaming state. Is provided.

As shown in FIG. 2, a substantially circular game region 13 surrounded by an outer rail 11 and an inner rail 12 is formed on the game board 10. The game ball launched by the launching device jumps into the game area 13 through a passage formed between the outer rail 11 and the inner rail 12.
A center case 14 is mounted at the center of the game area 13, and an LCD panel 15 a of a symbol display device 15 (not shown in its entirety) is arranged so as to be surrounded by the center case 14. Are provided with a warp inlet, a warp rod, a stage and the like as well known.
A lamp windmill 19 is installed on the left and right sides of the center case 14, and a gate (passage opening) 21 is installed above the left lamp windmill 19. When the game ball launched to the gate 21 passes, the normal symbol is variably displayed on the normal symbol display device 25 provided at the upper right of the LCD panel 15a. When the normal symbol stops at a predetermined winning symbol, the wing 21 provided immediately below the center case 14 is opened, and the winning opening provided with the wing 21 serves as a starting port 22 for changing the special symbol. .
When a game ball wins at the starting port 22, the special symbol fluctuates on the LCD panel 15a. When the special symbol stops at a predetermined symbol, the big winning port 30 provided immediately below the starting port 22 is opened a predetermined number of times. (The figure is when open).
A normal symbol storage LED 31 and a special symbol storage LED 32 are integrally provided on the upper left of the LCD panel 15a, and a plurality of winning holes 24 are provided on both sides of the start port 22.
An out port 28 is provided immediately below the big winning port 30, and game balls that have been launched into the game area 13 and have not won the winning port are collected on the back of the gaming machine.
Although a large number of game nails 16 are planted in the game board 10, these are well-known and will not be described.
Further, side lamps 26 are provided on both sides of the game area 13, and a plurality of upper lamps 27 are provided along the outer rail 11 at the upper part of the game board 10. The side lamps 26 and the upper lamps 27 correspond to notification means, and are provided to increase the player's taste and notify the player and the store clerk of the game state.

  FIG. 3 is a back view of the pachinko machine 50 viewed from the back side. As shown in the drawing, a mechanism board 70 to which the above-described game board 10 is detachably attached is housed in the above-described outer frame 51. The mechanism panel 70 is provided with a ball tank 71, a tank rail 72, and a dispensing device 73 from above. With this configuration, if there is a winning game ball in the winning slot on the game board 10, a predetermined number of gaming balls can be discharged from the ball tank 71 through the tank rail 72 to the above-described upper plate 55 by the payout device 73. .

  Also, on the back side of the pachinko machine 50, a main control device 80, a payout control device 81, a symbol control device 82, an audio / lamp integrated control device 83, a launch control device 84, and a power supply board 85 are provided (the payout control device 81, The symbol control device 82, the voice / lamp integrated control device 83, the launch control device 84, and the power supply board 85 correspond to the sub-control device), and the frame external connection terminal 79 and the panel external connection terminal are located in the upper right part of the mechanism panel 70. 78 is provided. The frame external connection terminal 79 is connected to the glass frame 60 and the payout control device 81 so that the open state of the glass frame 60 and the payout state of the rental balls can be output to the hall computer. The board external connection terminal 78 is connected to the main control device 80, and when the game ball has won the starting port 22, the state that the wings 21 that are opened due to the normal symbol hit are open or a special symbol hit. Thus, it is possible to output to the hall computer that the large winning opening 30 to be opened is open, the payout state of the prize ball and the lottery probability of the special symbol are in a high probability state. In addition, a signal indicating that the lottery probability of a special symbol is in a high probability state is output when a predetermined condition is satisfied at the normal probability and the high probability state is entered, and when the high probability state is entered immediately after the power is restored. Different types of signals are used. In this embodiment, the type of signal is varied depending on the voltage output from one terminal. However, the present invention is not limited to this, and a signal may be output from each other terminal to the hall computer. . In this way, by changing the type of signal that is output even in the same high probability state, the store clerk notices early if a state that does not occur very often occurs, such as a high probability state immediately after power recovery. Can detect fraud early.

The voice / lamp integrated control device 83 includes a sound source IC, an amplifier, and the like, and controls driving of the speaker 51 in response to a command from the main control device 80.

  The processing executed by the 8-bit one-chip microcomputer (hereinafter simply referred to as “microcomputer”) in the main controller 80 of the pachinko machine 50 having the circuit configuration described above will be described with reference to the flowchart shown in FIG.

  The flowchart shown in FIG. 5 represents a main process executed by the microcomputer of the main controller 80, and is a process periodically executed by a hardware interrupt about every 2 ms. In this embodiment, each process from S10 to S65 is a process that is executed only once in the interrupt process and is referred to as “main process”, and is repeated as long as time permits within the remaining time after executing this main process. The processing of S70 and S75 to be executed is referred to as “residual processing”.

  When a hardware interrupt is executed by the microcomputer, it is first determined whether or not the interrupt is a normal interrupt (S10). This determination process is performed by determining whether or not the value of a predetermined area of the RAM as a memory is a predetermined value. When the process executed by the microcomputer shifts to this process, the normal process is executed. It is for judging whether it is okay. If the interrupt is not normal, microcomputer runaway due to noise or the like may be considered when power is turned on. However, microcomputer runaway may be considered to be almost impossible due to recent technological improvements, and is usually when power is turned on. When the power is turned on, the value of the predetermined area of the RAM is different from the predetermined value.

  When it is determined that the interrupt is not normal, the initial value is written to the memory work area, that is, the initial value is written to the memory work area, such as writing a predetermined value to the predetermined area of the memory, and using a special symbol and a normal symbol as an initial symbol. (S15), the process proceeds to the remaining process.

  If an affirmative determination is made with a normal interrupt, first, an initial random number update process is executed (S20). This process is an increment process that increments the initial random number value by 1 each time this process is executed. The initial random number value before this process is incremented by one, but the random value before this process is executed is the maximum value. When it is “299”, it returns to the initial value “0” in the next processing, and 300 integers from “0” to “299” are repeatedly generated in ascending order.

The success / failure random number update process (S25) following S20 is an increment process that is incremented by 1 every time the process is executed, as in the initial random number update process. However, when the maximum value “299” is reached, The initial random number is set to an initial value (hereinafter referred to as “update initial value”), and the process of incrementing by +1 for each interrupt is continued and a value “1” less than the update initial value (hereinafter referred to as “update maximum value”). In the next processing, 300 integer values from “0” to “299” are repeatedly created with the initial random number at that time as an initial value.
That is, +1 is added for each interrupt process, and setting the elements constituting the random number to an integer value from “0” to “299” is not different from the initial random number. In this interrupt processing, the update initial value at that time is set as the initial value, and +1 is added for each interrupt until the update maximum value is reached, and the next update initial value is set as the initial value. As a result, the random number is set to 300 integer values from “0” to “299” as elements constituting the random number, and is incremented by +1 for each interrupt process. Since it is changed to a value determined by the initial random number, the value of the random number can be made unpredictable. In addition, the constituent elements of the random number determined by the update initial value and the update maximum value are the same as the 300 integer values “0” to “299” that are the same as the conventional pass / fail random numbers, and thus the elements constituting the random numbers The appearance rate is made uniform.

  The jackpot symbol random number update process (S30) is configured as a counter that repeatedly creates 15 integers “0” to “14”, and is incremented by 1 every time this process is exceeded and the initial value is set to “0”. Return. Each of the 15 random numbers “0” to “14” is “111”, “222”, “333”, “444”, “555”, “666”, “ 777 ”,“ 888 ”,“ 999 ”, [AAA],“ BBB ”,“ CCC ”,“ DDD ”,“ EEE ”,“ FFF ”, respectively.

  The off symbol random number update process (S35) is composed of a random symbol for the left symbol, a random number for the middle symbol, and a random number for the right symbol, and is used as a miss symbol when it is not a big hit. The left symbol random number is configured as a counter that repeatedly generates 15 integers “0” to “14”, and is incremented by 1 every time this process is exceeded, and returns to the initial value “0”. The medium symbol random number is configured as a counter that repeatedly creates 15 integers from “0” to “14”. When the left symbol random number returns to “0”, it is incremented by 1 every time this process exceeds the maximum value. Return to "0". The right design random number is configured as a counter that repeatedly creates 15 integers from “0” to “14”. When the medium design random number returns to “0”, it is incremented by 1 every time this process is exceeded and exceeds the maximum value. Return to "0".

  The normal symbol random number update process (S40) is configured as a counter that repeatedly creates seven integers “0” to “6”, and is incremented by 1 every time this process is exceeded, and is set to an initial value “0”. Return. By the random number update processing (S20 to S40) described above, the initial random number, the success / failure random number, the jackpot symbol random number, the off symbol random number, and the normal symbol random number are respectively updated.

In the subsequent winning confirmation process S45, confirmation of winning of the start port 22 and input processing of each switch provided in the pachinko machine 50 and connected to the main controller 80 are executed.
In this embodiment, when a game ball wins the winning opening 22, a plurality of random numbers such as a big hit determination random number, a big hit symbol determination random number, a variation pattern determination random number, a reach determination random number, etc. are acquired. The number of the random numbers is merely stored and the plurality of random numbers are not stored on hold, even if the game ball wins the start opening 22 when the storage is full. ing.

  Subsequently, a success / failure determination process (S60) is performed as condition establishment determination means for determining whether or not a big hit. This success / failure determination process will be described in detail later with reference to FIGS. When this success / failure determination process (S60) ends, each input / output process (S65) such as an image output process is subsequently executed.

  In each output process (S65), as the game progresses, the main controller 80 controls the symbol controller 82, the payout controller 81, the launch controller 84, the voice / lamp integrated controller 83, the prize winning solenoid 30c, and the like. To execute each output process. That is, when it is detected by each input process (S45) that there is a winning game ball at each winning port on the game board 10, the winning ball data is sent to the payout control device 81 so as to pay out the gaming ball as a winning ball. The process of outputting the sound data corresponding to the gaming state to the voice / lamp integrated control device 83 is an error signal to notify the symbol control device 15 that the pachinko machine 50 is in error when there is an abnormality. , And, when a big hit occurs, a big hit process is executed.

  The above-described remaining process subsequent to this process is composed of an outlier symbol random number update process (S70) and an initial random number update process (S75), and is the same process as S20 and S35 described above. These two processes form an infinite loop and are repeatedly executed as long as time is allowed until the next interrupt is executed. The time required to execute this processing from S10 to S65 described above differs for each interrupt depending on whether or not to execute the jackpot processing, the difference in the display mode of special symbols, and the like. As a result, the number of times the remaining process is executed is different for each interrupt, and the interrupted process shown in FIG. 5 is executed once, and the values to be updated (added) of the symbol random number and the initial random number are uniform. Disappear. Thereby, there is no possibility that the initial random number and the out-of-sequence random number are synchronized with the random number. In the present embodiment, the update of the random number is changed according to the value of the initial random number, so there is no possibility of synchronization. The normal symbol random number update process (S40) described above may also be executed in the remaining process.

  6 and 7 are flowcharts showing details of the success / failure determination process (S60), and FIG. 8 is a flowchart showing a special game process (S700) executed subsequent to the success / failure determination process S60.

The success / failure determination process will be described with reference to FIG. 6. First, it is determined whether or not the condition device is in operation (whether or not a special game right flag indicating the occurrence of a special game right (bonus) is set) (S601). ). If it is determined that it is in operation, the special game process (S700) of FIG. 8 is executed, and if it is determined that it is not in operation, it is next determined whether or not the special symbol is being variably displayed (S604). . If it is determined that the fluctuation display is not being performed, it is determined whether or not the special symbol is being confirmed (S605). If it is determined in S605 that the confirmed symbol is not being displayed, it is determined whether there is a pending storage (S606). If an affirmative determination is made in S604, the process proceeds to the process of FIG. 7A. If an affirmative determination is made in S605, the process proceeds to the process of FIG. If an affirmative determination is made in S606, it is determined whether the current state is in a high probability state or a normal probability state (S607). If the current state is in a high probability state (S607: YES), the stored random number value is determined as a high probability state. If it is not in the high-probability state (S607: NO), whether or not the stored random number is determined is determined using the normal probability table (S609).
Next, it is determined whether or not the result of the determination in S608 or S609 is a big hit (S610). If the determination is affirmative, a big hit symbol is determined (S611) and a fluctuation pattern is determined (S612). On the other hand, if the determination is negative, determination of an outlier symbol (S613) and variation pattern are determined (S614). After S612 or S614, processing for transmitting a change start command from the main control device 80 to the voice / lamp integrated control device 83 is performed (S615), and a change start command is sent from the voice / lamp integrated control device 83 to the symbol control device 82. To do. When the symbol control device 82 receives the variation start command, the symbol display device 15 starts the variation of the special symbol. The variation start command is transmitted together with the symbol determined in S611 or S613 and the variation pattern determined in S612 or S614.

By the way, in the normal state, only one of the 300 random numbers is a winning value, but in the probability variation state, there are five winning values. Since the same one counter (0 to 299 is incremented by 1) is also used for the probability change state in the normal state, the normal table (1 for normal state) is used to determine whether or not it is hit according to these two states. Two tables, a table for only one value) and a table for probability variation (a table of five winning values), determine whether the extracted value is correct by referring to the table according to the current (probability or normal) To do.
Of course, it is natural to determine the variation pattern by looking at the reach random number, variation pattern determination random number, and out-of-range design random number acquired at the time of winning a prize, and the variation shortening function (probably stored at the start of variation in the probability variation state, short time state and normal state) The variation pattern is determined by confirming whether the function (actuated when there are two or more) is activated or not activated. That is, the fluctuation shortening function is always activated during probability change and time reduction, and the one with the short variation time is selected when the fluctuation shortening function is in operation.

  In addition, the pachinko machine 50 according to the present embodiment is configured as a probability change machine, and is a jackpot symbol in a game after the jackpot game is executed after being stopped and displayed with a specific symbol (special game notification symbol) among the special symbols. A high-probability state in which the probability of stopping and displaying is increased is executed, and a short-time state in which the symbol variation time is shortened. Here, the time-short state is a state in which the fluctuation time of the special symbol and the normal symbol is shortened, and the opening time of the ordinary electric accessory is extended due to the normal symbol being elected, and the high probability state is a special symbol in addition to the time-short state. This is a state where the winning probability of becomes high.

  Next, the details of the determination means in S610 for determining whether or not it is a big hit will be described. In the normal state, the success / failure determination value is “1”, and the probability variation state is “1”, “3”, “5”, “7”, “9”. As described above, the appearance rates of the 300 integer values “0” to “299” constituting the success / failure random number are uniform, and the success / failure extracted at the timing when the game ball wins the start opening 22 as the start opening. The value of the random number is a randomly extracted value because the winning timing cannot be adjusted in minute time units as compared with 2 ms which is the minute time of the hard interrupt, and the success / failure random number functions as a complete random number. Accordingly, the probability that the extracted random number value matches the true / false determination value and is a big hit is 1/300 in the normal state and 1/60 (= 5/300) in the probability variation state. In the present embodiment, the probability that the jackpot is generated shifts from the low probability state to the high probability state. In this embodiment, the value of the jackpot symbol random number in the interrupt processing when the jackpot occurs is “1”, “3”, “ 5 ”,“ 7 ”,“ 9 ”,“ 11 ”, and“ 13 ”(hereinafter referred to as“ high probability random value ”), with a high probability of 7/15 when a big hit occurs. Transition. If the value of the jackpot symbol random number when the jackpot is generated again in the probability variation state is a high probability random number value, the higher probability state continues. That is, once in a high probability state, there is a possibility that a high probability will continue with a probability of 7/15.

  In addition, the average variation time of the special symbol and the average variation time of the normal symbol are set to be shorter in the probability variation state and the short time state than in the normal state. In addition, the minimum value is provided so that the shortest fluctuation time of a special symbol may become more than predetermined time (for example, about 5 second). Further, the opening time of the start port 22 is set to be longer in the probability changing state and in the short time state than in the normal state. Not all fluctuations are short just because they are in a probabilistic state or a short-time state, but super-reach that makes the player especially expect to win a big hit and fluctuations that make big hits are as long as normal fluctuations. Is called.

  The variation shortening function that shortens the variation of the special symbol operates unconditionally in the probability variation state and the short time state. In the normal state, the fluctuation shortening function operates when there are two or more reserved memories at the start of fluctuation, and does not operate when the number is less than two. The probability of hitting a normal symbol is always set to a constant value of 1/2. However, in implementing the present invention, the probability of hitting a normal symbol may be set high in the short-time state and the probability variation state.

  Next, FIG. 7A is a process executed when it is determined in S604 that it is changing, and first, it is determined whether or not the symbol change time has passed a predetermined time (S621). If it is determined that the predetermined time has not elapsed, the process proceeds to the special game process S700 of FIG. 8, and if it is determined that the predetermined time has elapsed, a symbol stop command for instructing to stop the variation of the symbol is integrated with the sound / lamp. The voice / lamp integrated control device 82 transmits a symbol stop command to the symbol control device 82 (S622). Then, it is determined whether or not the symbol determined based on the determination result of S610 (S611, S613) is a combination that is a big hit (S623).

  Next, a description will be given of the processing in the case where an affirmative determination is made in S623 that the jackpot is a combination (S623: Yes). First, the determined symbol display setting process for causing the symbol display device 15 to display the determined jackpot symbol. Is executed (S624), and processing for starting the condition device operation is executed (S625). Next, it is determined whether or not a probability change flag is set (S626). If the probability variation flag is set, the probability variation flag is ended (S627). If the probability variation flag is not set, it is determined whether the time reduction flag is set (S628). If the time reduction flag is set, the time reduction flag is ended (S629). If the time reduction flag is not set, the process proceeds to the special game process S700 of FIG.

  If it is determined in S623 that the symbol combination is not a big hit, a definite symbol display setting process for displaying the off symbol on the symbol display device 15 is executed (S626), and it is determined whether or not the time reduction flag is set. (S627). If the time reduction flag is set, -1 is performed from the current remaining short time number, and the process of setting the value to the remaining short time number is performed (S628), and it is determined whether the short time number is 0 (S629). ). If the number of time reductions is 0, processing for ending the time reduction flag is performed (S630).

  In the process of FIG. 7B performed when an affirmative determination is made in S605 of FIG. 6, it is determined whether or not the display time of the fixed symbol has ended (S631). If the determination is affirmative, a fixed symbol display process is performed (S632). ), If negative determination is made in S631, the process proceeds to the process of FIG.

  Next, the special game process S700 shown in FIG. 8 will be described. First, it is determined whether or not the operation of the condition device started in S625 is in operation (S701). If it is determined that it is not operating, the process returns to the return, and if it is determined that it is operating, it is determined whether or not the special winning opening 30 is open (S702). Next, the processing in the case where it is determined in S702 that the big prize opening 30 is not open (S702: No) will be described. First, whether or not the effect display of the jackpot start is being displayed on the LCD 15a. Judgment (S703), whether or not the jackpot 30 is in the closing interval between the jackpot game period and the next jackpot game period (S704), the jackpot end effect display is being displayed on the LCD 15a It is determined whether or not there is (S705).

  If it is determined that the jackpot start effect is not being performed (S703: No), the interval is not being performed (S704: No), and the jackpot end effect is not being performed (S705: No), the jackpot symbol and the jackpot state are stored. The storage process is executed (S706), and the big hit start effect process (S707) is performed. On the other hand, if a positive determination is made in each of the determinations S703 to S705, the process returns.

  Next, a description will be given of the processing in the case where it is determined in S702 that the big prize opening 30 is open (S702: Yes). First, in S710, whether or not there are ten prizes in the big prize opening 30 is determined. Determine. If there are 10 winnings (S710: Yes), the process proceeds to S712. If there are not ten winnings (S710: No), it is determined whether or not the opening time of the special winning opening 30 has ended (S711). If the opening time of the special winning opening 30 has ended (S711: Yes), the process proceeds to S712. If the opening time of the big winning opening 30 has not ended (S711: No), the process returns. In S712, the closing process of the special winning opening 30 is executed, and it is subsequently determined whether or not the current round is the final round of the special game (S713). If it is the final round (S713: Yes), the process proceeds to S716. If it is not the final round (S713: No), it is determined whether or not the game ball has passed the specific area (V) (S714). If it passes through the specific area (V) (S714: Yes), the big hit interval process is executed (S715) and the process returns to the return. If it does not pass through the specific area (V) (S714: No), the process proceeds to S716.

In S716, a jackpot end effect process is executed, and a conditional device stop process is executed to end the special game right (jacket) flag (S717).
Subsequently, it is determined whether or not the winning symbol is a probability variation symbol (S718). If the determination is negative, the processing proceeds to the processing of FIG. 8B. If the determination is affirmative, the probability variation flag operation processing (S719) is performed, and the process returns.

  The process of FIG. 8B is performed when it is determined that the special symbol hit in S718 is not a probability variation symbol, that is, a normal symbol. First, it is determined whether or not the big hit state is a probable variation state (S721). If the determination is negative, the process returns to the return. If the determination is affirmative, processing such as a time-short flag operation process, for example, setting the number of time reductions to 100 is performed (S722). Return to return.

  In this way, if the jackpot symbol is a probability variation symbol (odd symbol), the probability variation flag is operated as it is, and the return is performed. On the other hand, if the jackpot symbol is an even symbol, that is, a normal symbol, the state at the time of the jackpot is a probability variation state. If so, the time reduction is executed, so the time reduction flag is activated. If the state at the time of the big hit is the normal state, the process returns as it is.

  In the present embodiment, when a big hit is made with an odd number of symbols during the normal period, the probability variation period continues until 10,000 hits after the big hit ends or until the next big hit. If a big hit with an odd symbol during this probability change period, the jackpot game will be in a probabilistic state from the end, and if a big hit with an even symbol during the probability change period, it will fluctuate 100 times from the end of the big hit game, or It becomes short time until it hits a big hit. At this time, when 100 short-time fluctuations are over, the normal period is reached. If the jackpot is hit with an odd number of symbols during the short time period, the probability changes state, and if the jackpot is hit with an even number of symbols, the normal state is entered. If a big hit is made with an even number of symbols during the normal period, the normal state remains.

A game state storage means (RAM) 121 is provided for storing whether the game is in a state, a short-time state, or a big hit state. The game state storage means stores the state even when the pachinko gaming machine 50 is not turned on. Is to be retained. In the present embodiment, the game state storage means 121 is provided in the voice / lamp integrated control device 83, but the present invention is not limited to this and may be provided in another sub-control device.

  Next, in FIG. 9, the power supply and signal flow in the main controller 80, the power supply board 85, the payout controller 81, the voice / lamp integrated controller 83, and the symbol controller 82 are shown. The power supply board 85 of the pachinko machine 50 receives the AC 24V power provided on the pachinko parlor side via the power switch 100, and the power generation circuit receives the main controller 80 and the payout control as shown in the figure. Normal power is supplied to each part of the gaming machine including the device 81, the voice / lamp integrated control device 83, and the symbol control device 82.

  The full-wave 24V output in the power generation circuit is input to a power supply voltage monitoring circuit provided in the power supply board 85, and a reset signal is generated in the power supply board 85 based on the detection result of the presence / absence of the full-wave 24V output by the power supply voltage monitoring circuit. The circuit outputs or cancels the reset signal to the main controller 80 and the sub controller. That is, the power supply voltage monitoring circuit determines that the full-wave 24V output is stopped if the non-output state higher than the predetermined reference voltage is maintained for a predetermined time, and the reset signal generation circuit is reset according to the determination that the full-wave 24V output is stopped. Output a signal. On the other hand, when full wave 24V output is started, the reset signal is canceled. Here, the output of the reset signal is to output a low level signal, and the release is to change from the low level to the high level. As shown in FIG. 10, the reset signal is released after the delay time Ta from the detection time of the full-wave 24V output.

  The output of the reset signal generation circuit is output to the reset terminal of the CPU of each control device via the delay circuits of the main control device 80, the payout control device 81, the voice / lamp integrated control device 83, and the symbol control device 82, respectively. As shown in FIG. 10, in the delay circuit of the main controller 80, a predetermined delay time Tc is given to cancel the reset signal, and in the delay circuit of the payout controller 81, a predetermined delay time Td is given to cancel the reset signal, In the delay circuit of the sound / lamp integrated control device 83, a predetermined delay time Te is given to cancel the reset signal. Although not shown in FIG. 10, in the delay circuit of the symbol control device 82, a predetermined delay time Te is given to the release of the reset signal as in the voice / lamp integrated control device 83.

A power failure signal generation circuit is provided on the power supply board 85 with the output of the power supply voltage monitoring circuit as an input. The signal is output to the NMI terminal of the CPU of the device 83). The power failure signal is a signal that changes from a high level to a low level when the power is cut off, and the output timing is set so that it is output before the reset signal is output.
The power supply board 85 is configured to generate a DC5V backup power supply (VBB) by a backup power supply generation circuit including a capacitor. The backup power supply (VBB) output is output from each control device (main control device 80, It is output to the backup terminal (VBB) of the CPU of the payout control device 81 and the voice / lamp integrated control device 83), and retains the storage contents of the RAM of each control device when the power is turned off. The contents of the RAM of the main controller 80 and the payout controller 81 are all stored and retained, and the contents of the RAM of the voice / lamp controller 83 are in what state (normal probability state, high probability state, short time state, jackpot) when the power is turned off. Only the content indicating whether the state is one of the states) is stored and held (corresponding to the game state storage unit 121).

  In the power supply board 85, as shown in FIG. 11, the RAM clear switch 101 for clearing the RAM of the main controller 80 and the RAM of the payout controller 81 and the RAM of the voice / lamp integrated controller 83 are cleared. A storage RAM clear switch 102 is provided. The state storage RAM clear switch 102 is provided inside a cover 107 made of a see-through member, and the cover 107 is not shown in the figure but is provided with a key and is not easily opened. It is configured. Further, a RAM clear content setting switch 103 is provided in the cover 107. This RAM clear content setting switch 103 selects a content to be cleared when a RAM clear operation is performed from among a plurality of types of content stored in the RAM as shown in FIG. It is a switch to do. Conventionally, when a RAM clear operation was performed, all the contents stored in the RAM were cleared, but this was inconvenient for testing a gaming machine and checking for a failure location. In order to do so, it has such a configuration. Recently, there have been many cases of fraud using RAM clear, but the above-described fraud can be prevented as much as possible by adopting such a configuration.

In the following, the contents of the above-mentioned fraud and methods for solving it will be briefly described.
The current gaming machine uses an initial random number and a success / failure random number (big hit random number) to randomize the value of the random number acquired when the game ball wins the starting opening. However, when the RAM is cleared, the initial random number value and the pass / fail random number value start from 0, so the time until the updated pass / fail random number value reaches the winning value is known, and accordingly ( There is a fraud in which a game ball is won at the start opening 22 and won a big hit (using a sensory device or the like).
In order to prevent this fraud, if the RAM clear switch 101 is provided in a cover or the like with a lock like the state storage RAM clear switch 102 of this embodiment, the RAM can not be easily cleared. However, it takes a long time to perform the RAM clear operation. However, by adopting a configuration in which the contents to be cleared from the RAM can be selected as in the present embodiment, fraud can be prevented as much as possible, and the store clerk can easily perform a RAM clear operation.

Next, although it is possible with the configuration of FIG. 12A, it will be described with reference to FIG.
When the RAM clear content setting switch 103 is pressed, the character displayed on the setting content display device 104 provided on the power supply board 85 is switched from “A” to “B” or from “B” to “A”. “A” is a display indicating that the memory other than the memory related to the random number (the initial random number, the current value of the random number) is cleared when the RAM clear operation is performed, and “B” is the RAM clear. This is a display indicating that all contents stored in the RAM are cleared when an operation is performed. As described above, the storage related to the random number is the update state (current storage) of the initial random number and the success / failure random number. The setting content display device 104 normally displays “A”, and is changed to “B” display by removing the key and the cover 107 and pressing the RAM clear content setting switch 103 once. The display of “B” is switched to the display of “A” when a predetermined time has elapsed and when the power of the pachinko gaming machine 50 is cut off. Even if “B” is displayed, the next time the RAM is cleared, “A” is displayed. Therefore, when the RAM is cleared by displaying “B” (when all the contents stored in the RAM are cleared), The key and cover 107 must be removed. Usually, since the memory related to the update of the random number stored in the RAM needs to be cleared only when it is carried into the hall from the manufacturer, the RAM clear content setting switch 103 is hardly pressed.
In other words, even if the player intends to perform the above fraud and presses the RAM clear switch, the memory related to the update of the random number is not cleared, and therefore the fraud cannot be performed. In addition, since the memory associated with the update of the random number is rarely cleared, there is no problem even if the key or the cover 107 is provided.

  The state storage RAM clear switch 102 is also provided so that fraud can be detected at an early stage, but it is only necessary when shipping from a manufacturer to a pachinko parlor, and usually does not need to be cleared. Is provided.

  In addition, the power supply board 85 has a plurality of connectors for connecting to the control device, a fuse provided to avoid a failure of the gaming machine due to overcurrent, and the game state stored in the backup means 120 and backup. A backup notification lamp 105 indicating that the contents of the means 120 have been cleared, a game state storage notification lamp indicating that the gaming state is stored in the gaming state storage means 121 and that the contents of the gaming state storage means 121 have been cleared. 106 is provided.

  FIG. 12C shows another embodiment in which the RAM clear content setting switch 103 is used. In this configuration, the main control device 80, the payout control device 81, and the voice / lamp integrated control device 83 (stored by the game state storage means 121) are provided only by the RAM clear switch 101 without providing the state storage RAM clear switch 102. The contents of the main control device 80 and the payout control device 81 are cleared or the RAM of the voice / lamp integrated control device 83 is cleared by pressing the RAM clear content setting switch 103. It is possible to switch between clearing the main control device 80, the RAM of the payout control device 81, and the RAM of the voice / lamp integrated control device 83 all at once.

  FIG. 12D shows another embodiment using the RAM clear content setting switch 103. In this configuration, when the pachinko gaming machine 50 is turned on while pressing the RAM clear switch 101 and the RAM clear content setting switch 103, the memory other than the memory related to the random number is cleared, and when only the RAM clear switch 101 is pressed, the RAM is turned on. All the contents stored in (1) are cleared (the RAM of the voice / lamp integrated control device 83 may be cleared or may not be cleared). Although the configuration shown in FIG. 12D is not perfect, it is possible to prevent the RAM clearing due to the above-described fraud and malfunction as much as possible.

Next, the flow of signals will be described with reference to FIG. The RAM clear content setting switch 103 shown in FIG. 10 adopts the configuration shown in FIG.
The reset signal is released after the time Ta has elapsed since the power switch 100 was turned on (T2), and the reset signal is released after the time Tc has elapsed in the CPU of the main controller 80, and in the CPU of the payout controller 81 after the time Td has elapsed. When the CPU of the lamp integrated control device 83 becomes effective after the time Te has elapsed, the CPU of each control device starts a security check from the time when it becomes effective. Here, the delay time Tc of the CPU of the main control device 80 is set longer than the delay time Td of the CPU of the payout control device 81, and the delay time Td of the CPU of the payout control device 81 is the CPU of the voice / lamp integrated control device 83. Is set longer than the delay time Te. Although the security check time Tb depends on the CPU type, system clock frequency, etc., in this specific example, it is used for all of the CPU of the main controller 80, the CPU of the payout controller 81, and the CPU of the voice / lamp integrated controller 83. In LE2080A-PA (system clock frequency 6 MHz), it was set to 185 ms. As is well known, the security check is to check whether or not the contents of the ROM into which the progress of the game is written by each CPU, which is a one-chip microcomputer, is normal.

  The security check time Tb of the CPU of the main control device 80 is equal to or longer than the CPU of the payout control device 81, and the security check start time of the CPU of the main control device 80 is earlier than the security check start time of the CPU of the payout control device 81. If it is to be executed later (Td <Tc), when the security check of the CPU of the main control device 80 is completed, the CPU of the payout control device 81 completes the security check, and the CPU of the main control device 80 writes to the ROM. When the game control is started in accordance with the programmed program, the CPU of the payout control device 81 has already executed the game control. As a result, even if the CPU of the main control device 80 immediately transmits data to the CPU of the payout control device 81 after the power is turned on, the CPU of the payout control device 81 finishes the security check and executes its own control. Can receive data. Further, the security check time Tb of the CPU of the payout control device 81 is equal to or longer than the CPU of the CPU of the voice / lamp integrated control device 83, and the security check start time of the CPU of the payout control device 81 is the voice / lamp integrated control device. If the security check of the CPU of 83 is executed later (Te <Td), when the security check of the CPU of the payout control device 81 is completed, the CPU of the voice / lamp integrated control device 83 performs a security check. When the CPU of the payout control device 81 starts and controls the game according to the program written in the ROM, the CPU of the voice / lamp integrated control device 83 has already executed the control of the game. As a result, even if the CPU of the payout control device 81 immediately sends data to the CPU of the voice / lamp integrated control device 83 after the power is turned on, the CPU of the voice / lamp integrated control device 83 finishes the security check and controls itself. Since it is running, data can be received reliably.

  The RAM clear switch 101 is a push button type that is turned on only when pressed, and if the RAM clear switch 101 is turned on when the reset signal is released (T3), the RAM clear signal generating circuit is at a high level. A RAM clear signal, which is a signal, is output to the input ports of the main controller 80 and the payout controller 81 for a predetermined time. That is, the RAM clear signal is output only when the power is turned on when the reset signal is released. Here, the delay time Ta from turning on the power switch 100 to releasing the reset signal is set to 100 ms, for example. To generate the RAM clear signal, the power switch is turned on while pressing the RAM clear switch 101 (T1). . The CPU of each control device monitors the presence or absence of a RAM clear signal at the input port via the data bus.

  By turning on the power switch 100 while pressing the RAM clear switch 101, the RAM clear signal is output for a time Tg from the time when the reset signal is released. Here, the RAM clear signal output time Tg is longer than the time from reset signal release to security check completion (reset signal delay time Tc + security check time Tb) for the CPU of the main controller 80 that completes the security check later. By doing (Tf), the main controller 80 and the payout controller 81 can reliably receive the RAM clear signal after the security check is completed. The main control device 80 and the payout control device 81 determine whether or not a RAM clear signal is input after the security check is completed, and if so, the RAM is cleared.

  The state storage RAM clear switch 102 is a push button type that is turned on only when pressed, and if the state storage RAM clear switch 102 is on when the reset signal is released (T3), the state storage RAM The clear signal generating circuit outputs a state storage RAM clear signal, which is a high level signal, to the input port of the voice / lamp integrated control device 83 for a predetermined time. That is, the state storage RAM clear signal is output only when the power is turned on when the reset signal is released. Here, the delay time Ta from turning on the power switch 100 to releasing the reset signal is set to 100 ms, for example. To generate the state storage RAM clear signal, the power switch is turned on while pressing the state storage RAM clear switch. (T1). The CPU of the control unit of the voice / lamp integrated control unit 83 monitors the presence or absence of the state storage RAM clear signal at the input port via the data bus.

  By turning on the power switch 100 while pressing the state storage RAM clear switch 102, the state storage RAM clear signal is output for a time Th from the time when the reset signal is released. Here, the output time Th of the state storage RAM clear signal is longer than the time (reset signal delay time Te + security check time Tb) from the reset signal release to the security check completion for the CPU of the voice / lamp integrated control device 83. By doing (Tf), the voice / lamp integrated control device 83 can reliably receive the state storage RAM clear signal after the security check is completed. The voice / lamp integrated control device 83 determines whether or not the state storage RAM clear signal is input after the security check is completed, and if it is input, the RAM (content stored in the game state storage means 121) is stored. clear.

  As described above, the RAM clear setting signal is configured as shown in FIG. 12d, and the RAM clear content setting switch 103 is a push button type that is turned on only when pressed, and the RAM clear is performed when the reset signal is released (T3). If the setting switch is on, the RAM clear setting signal generation circuit outputs a RAM clear setting signal, which is a high level signal, to the input ports of the main controller 80 and the payout controller 81 for a certain period of time. That is, the state storage RAM clear signal is output only when the power is turned on when the reset signal is released.

  By turning on the power switch 100 while pressing the RAM clear content setting switch 103, the RAM clear setting signal is output for a time Ti from the time (T3) when the reset signal is released. Here, the output time Ti of the RAM clear setting signal is set to be longer than the time (reset signal delay time Tc + security check time Tb) from the reset signal release to the completion of the security check for the CPU of the main controller 80 that completes the security check later. By making it longer (Tf), the main controller 80 and the payout controller 81 can reliably receive the RAM clear setting signal after the security check is completed. The main control device 80 and the payout control device 81 determine whether or not a RAM clear setting signal is input after the security check is completed. If the RAM clear setting signal is input (T5), all the contents stored in the RAM are set to be cleared. If not input (T13), the memory other than the random number is cleared. Set as follows.

  That is, when clearing all the contents stored in the RAM, the power switch 100 is turned on while pressing the RAM clear switch 101 and the RAM clear setting switch 103, and when clearing the memory other than the random number, the RAM clear switch The power switch 100 is turned on while pressing 101. Incidentally, nothing is cleared when the RAM clear switch 101 is not pressed when the power is turned on.

Next, the flow when the main controller 80 is turned on and the flow when the power is cut off will be described with reference to FIG.
FIG. 13A shows processing at power-on. First, an interrupt mode is set (S800), and RAM access is permitted (S801). Next, it is determined whether or not a RAM clear signal is input (S802). If not, it is determined whether or not the information generated at the time of power-off is normal (S803). A determination value of the RAM is calculated (S804). Next, it is determined whether or not the determination value of the RAM is normal (S805). If it is normal, the generated information at the time of power-off is cleared (S806), and the stack pointer is restored at the time of power-off (S807). ), A command transmission process at the time of power recovery (S808), an initial setting of the CPU peripheral device (S809), and it is determined whether or not an interrupt is permitted when the power is turned off (S810). If an interrupt is permitted when the power is turned off (S810: YES), interrupt permission is set (S811), jumps to the program address when the power is turned off, and if an interrupt is not permitted when the power is turned off (S810: NO) As it is, the processing is carried out at the program address when the power is turned off.

If a RAM clear signal has been input in S802 (S802: YES), it is determined whether or not a RAM clear setting signal has been input (S812). If it has been input, the processing from S813 onward is performed. Note that the process of S813 is performed in the same manner also when NO in S803 and NO in S805. In S813, all the contents stored in the RAM are cleared to 0, stack pointer setting (S814), RAM initial setting (S815), CPU peripheral device initial setting (S816), and interrupt permission setting (S817) are performed.
If the RAM clear setting signal is not input in S812 (S812: NO), the memory other than the random number is cleared to 0 (S818), the stack pointer is set (S819), and the CPU peripheral device is initialized ( S820), interrupt permission setting (S821) is performed.

  FIG. 13B shows processing when power is cut off. First, all used registers are saved (S830), stack pointer is saved (S831), RAM judgment value is calculated and saved (S832), and power is cut off. Information is stored (S833), and access to the internal RAM is prohibited (S834).

Next, referring to FIG. 14, the flow when the voice / lamp integrated control device 83 is turned on and when the power is cut off will be described.
FIG. 14A shows a process at power-on. First, an interrupt mode is set (S900), and access to the RAM is permitted (S901). Next, it is determined whether or not the state storage RAM clear signal is input (S902). If not, it is determined whether or not the information generated when the power is shut off is normal (S903). In this case, the stack pointer is restored when the power is cut off (S904), the CPU peripheral device is initialized (S905), and the main controller communication error state is set (S906). Next, it is determined whether or not the power-off state is in a high probability state (S907). This is determined based on the contents stored in the storage processing of the occurrence information at the time of power-off described later. If YES is determined in S907, the notification pattern C is set to be performed (S908). The notification pattern C is a pattern that is different from the notification pattern that is notified when a predetermined condition is established at a normal probability and the state becomes a high probability state (details will be described later).
Normally, the sound / lamp integrated control device 83 and the symbol control device 82 are controlled only after receiving a command from the main control device 80. However, when the notification pattern C is set, the main control device 80 Even when there is no command, the notification is made.
Next, the information generated when the power is turned off is cleared (S909), and it is determined whether or not an interrupt is permitted when the power is turned off (S910). If an interrupt is permitted when the power is turned off (S910: YES), an interrupt permission is set (S911), jumps to the program address when the power is turned off, and if an interrupt is not permitted when the power is turned off (S910: NO) As it is, the processing is carried out at the program address when the power is turned off.

  If the RAM clear signal is input in S902 (S902: YES) and the information generated when the power is shut off is not normal (S903: YES), all the contents stored in the RAM in S912 are set to 0. Clear, stack pointer setting (S913), CPU peripheral device initial setting (S914), main controller communication error status setting (S915), interrupt permission setting (S916).

  FIG. 14B shows processing when power is cut off. First, all used registers are saved (S930), the stack pointer is saved (S931), the command data is read from the main control unit (S932), and the power is turned off. Time generation information is saved (S933), and access to the built-in RAM is prohibited (S934). Saving the occurrence information when the power is turned off is a process of storing a gaming state (a normal probability state, a short time state, a high probability state, or a big hit state) immediately before the power is turned off.

  FIG. 15 is a diagram showing a notification pattern in each gaming state. FIG. 15A is an example in which different notification patterns are used in the normal probability state, the high probability state when the predetermined condition is satisfied at the normal probability, and the high probability state immediately after the power return. FIG. 15C shows an example in which the notification pattern of the normal probability state and the high probability state when the predetermined condition is satisfied at the normal probability is made the same, and only the high probability state immediately after the power return is made different. ) Is an example in which the notification pattern of the high probability state when the predetermined condition is satisfied at the normal probability state and the normal probability is changed to a similar notification pattern, and only the high probability state immediately after the power return is changed to a completely different notification pattern. The high-probability state immediately after power recovery is when the high-probability state is reached without going through the normal probability state after power recovery. As shown in (b) and (c) of FIG. 15, the notification pattern of the high probability state in the case where the predetermined condition is satisfied at the normal probability state and the normal probability state is the same or similar. It can be difficult to understand how long the high probability state has continued, increasing the preference. If this configuration is used as is in the conventional configuration (a configuration in which the notification pattern of the high probability state is the same or similar when the predetermined condition is satisfied at the normal probability state and the normal probability), the fraud early detection becomes impossible. However, as in this embodiment, the notification pattern in the high probability state immediately after the power return is made different from the notification pattern in the high probability state when the predetermined condition is satisfied at the normal probability, so that the preference is improved. Early detection of fraud is possible. Differentiating the notification pattern means that when the notification is performed using an LED or a lamp, the notification pattern may be different depending on the brightness level, the timing of turning on and off, the difference in emission color, etc. When using a speaker for sound, it may be possible to change the notification pattern depending on the sound level, tempo, song difference, etc.When performing notification by display, the background and design color differences, display contents It is conceivable to change the notification pattern depending on the difference (character, etc.). Moreover, when performing notification by display, one may display “high probability state” and the other may display “high probability state (power failure recovery)”.

Next, another embodiment will be described with reference to FIG.
The notification pattern in the high probability state when the predetermined condition is established in the normal probability state and becomes the high probability state is different from the notification pattern in the high probability state in the case of the high probability state immediately after the power is restored, and If the content stored in the backup unit 120 and the content stored in the game state storage unit 121 are different, the notification condition in the normal state, the predetermined condition is established in the normal probability state, and the content is high. This is an example in which the notification pattern in the high probability state when the probability state is reached and the notification pattern different from the notification pattern in the high probability state when the high probability state immediately after the power is restored are shown.
FIG. 16 differs from FIG. 9 in that the game state storage means 121 is provided in the payout control means, and the payout control means is provided so as to be capable of bidirectional communication with the main control device. Further, the payout control means 81 is configured to control the notification means via the voice / lamp integrated control device 83 or the symbol control device 82. In order to determine whether or not the content stored in the backup means 120 and the content stored in the game state storage means 121 are different from each other, the main control device 80 (the control device provided with the backup means 120). And a payout control device 81 (a control device provided with the gaming state storage means 121) are preferably capable of bidirectional communication.
In the one-way communication from the main control device 80 to the payout control device 81, it is determined whether or not the content stored in the backup unit 120 is different from the content stored in the game state storage unit 121. Although it is possible, if the ROM provided in the main control device 80 has been replaced with a ROM that outputs false information (actual probability is true despite the fact that the probability of jackpot is high) It becomes impossible to detect fraud early.
However, if the main control device 80 and the payout control device 81 are configured to be capable of bidirectional communication so that the payout control device 81 can check the state of the main control device 80, it can be replaced with an illegal ROM. Early detection of fraud is possible.

In the present embodiment, a notification pattern in a high probability state when a predetermined condition is established in a normal probability state and a high probability state and a notification pattern in a high probability state in a case of a high probability state immediately after power recovery However, when the normal condition or high probability state is met and the predetermined condition is met and the short time state is reached, the alarm pattern during the short time state and the short time state immediately after the power is restored The notification patterns in the inside may be different, or both the high probability state and the short time state may be configured as described above. In other words, the gaming state storage means 121 stores a high probability state when the gaming state immediately before the power interruption is a high probability state, and the gaming state immediately before the power interruption is a short-time state. Is configured to memorize that the time was short. The short-time state is a state where the special symbol's fluctuation time is shorter than normal, the normal symbol's fluctuation time is shorter than normal, or a normal symbol hit. This is a state in which the opening time of the wings is longer than usual, or a combination of these. As described above, since the player is more advantageous in the time reduction state than in the normal state, there is a possibility of being used illegally. However, with the above configuration, the fraud can be detected early. Note that the time-saving state is not usually started immediately after the power is turned on (although it may be started immediately after the power is turned on by the backup means).
It should be noted that a signal sent from the board external connection terminal 78 to the hall computer when the predetermined condition is established when the normal probability or the high probability state is established, and the outside of the panel when the time is shortened immediately after the power is restored. The signal sent from the connection terminal 78 to the hall computer may be different. The different method may have the same configuration as the different method in the high probability state.

  In the present embodiment, the first type gaming machine has been described as an example. However, the present invention is not limited to this, but the second type gaming machine, the third type gaming machine, the arrange ball gaming machine, the sparrow ball gaming machine, and the general electric role. This can be summed up for gaming machines such as machines and throat machines that have a normal state and a state advantageous to the player.
