As a result, the variation pattern of the variation display of the special symbol started this time is transmitted to the sub-control board 220. When the CPU 221 of the sub-control board 220 receives the variation pattern designation command, it recognizes the variation pattern of the variation display of the special symbol started this time based on the variation pattern designation command, and is based on (corresponds to) the recognized variation pattern. An effect (hereinafter, also referred to as "design variation effect") corresponding to a special symbol variation display (symbol variation game) is executed in the effect pattern.

In the process of selecting the variation pattern described above, the variation pattern selection table corresponding to various game progress states is referred to instead of always referring to the same variation pattern selection table. For example, the type of special symbol (1st special figure or 2nd special figure), the currently set game state, the result of the special figure hit determination, and the stored 1st special figure hold and 2nd special figure hold Refer to the variation pattern selection table corresponding to the number. By doing so, it becomes possible to select a variation pattern corresponding to various game progress states, and by extension, the CPU 221 of the sub-control board 220 can execute the effect with the effect patterns corresponding to various game progress states.

Further, the CPU 201 of the main control board 200 transmits a fluctuation stop command to the sub control board 220 when stopping the fluctuation display of the special symbol. Upon receiving this fluctuation stop command, the CPU 221 of the sub control board 220 transmits the timing at which the variation display of the special symbol (symbol variation game) ends to the CPU 221 of the sub control board 220.

The CPU 201 of the main control board 200 that variablely displays a special symbol (“identification information” in the present invention) corresponds to the “identification information display means” in the present invention.

<Holding special symbols>
When the game ball enters the first starting port 24 or the second starting port 25, the special symbol hit determination and the variation display are performed as described above, but these special symbol hit determinations and the variation display are performed. Rather than the game ball being played immediately after entering the first start port 24 or the second start port 25, the CPU 201 of the main control board 200 uses the acquired determination random number as a hold of a special symbol (special figure hold) in the RAM 203. I remember it once.

Specifically, when the game ball enters the first starting port 24, a determination random number is acquired, and the acquired determination random number is temporarily stored as the first special figure hold. Then, when the predetermined condition is satisfied, the special figure hit determination and the variation display of the first special figure are performed for the stored first special figure hold. Such first special figure reservation is stored up to four. The stored number of the first special figure hold (the number of the first special figure hold) is displayed on the first special figure hold display unit 53 of the segment display unit 50. That is, as shown in FIG. 4, two LEDs are arranged in the first special figure holding display unit 53, and in the first special figure holding display unit 53, both of the two LEDs are turned off. This indicates that the number of 1st special figure hold is 0, and lighting 1 LED indicates that the number of 1st special figure hold is 1, and by turning on 2 LEDs, it indicates that the number of 1st special figure hold is 1. It indicates that the number of 1st special figure hold is 2, and blinking 1 LED indicates that the number of 1st special figure hold is 3, and blinking 2 LEDs is the 1st. Indicates that the number of special figures on hold is four.

Further, when the game ball enters the second starting port 25, a determination random number is acquired, and the acquired determination random number is temporarily stored as the second special figure hold. Then, when the predetermined condition is satisfied, the special figure hit determination and the variation display of the second special figure are performed for the stored second special figure hold. Such second special figure reservation is also stored up to four. The stored number of the second special figure hold (the number of the second special figure hold) is displayed on the second special figure hold display unit 54 of the segment display unit 50. That is, as shown in FIG. 4, two LEDs are also arranged in the second special figure holding display unit 54, and in the second special figure holding display unit 54, both of the two LEDs are turned off. This indicates that the number of 2nd special figure reservations is 0, and by turning on 1 LED, it indicates that the number of 2nd special figure reservations is 1, and by turning on 2 LEDs, it indicates that the number of 2nd special figure reservations is 1. It indicates that the number of 2nd special figure hold is 2, and blinking 1 LED indicates that the number of 2nd special figure hold is 3, and blinking 2 LEDs is the 2nd. Indicates that the number of special figures on hold is four.

In the pachinko machine 1 of the present embodiment, even if the special symbol hold is stored, the special symbol hits during the variable display of any special symbol, the final display of any special symbol, or the big hit game. Judgment and fluctuation display of special symbols are not performed. In addition, when a plurality of special figure reservations are stored, regardless of whether they are the first special figure hold or the second special figure hold, the special figure regarding the special figure hold that is stored first is stored. Performs hit determination and variation display of special symbols (has a so-called sequential variation function of special symbols).

<Game state>
The CPU 201 of the main control board 200 has, as the gaming state of the pachinko machine 1 of this embodiment, "a gaming state related to the probability of being determined to be a big hit in the special figure hit determination" and "entering the gaming ball into the second starting port 25". The "game state related to the ball frequency" is appropriately set. Of these, a "low probability state" or a "high probability state" is set as the "game state related to the probability of being determined to be a big hit in the special figure hit determination". The "low probability state" is a state in which the probability of being judged as a big hit in the special figure hit judgment is low (the probability is about 1/100), and the "high probability state" is determined as a big hit in the special figure hit judgment. It is a state in which the probability of being done is high (the probability is about 1/10).

Further, as the "game state related to the frequency of entering the game ball into the second starting port 25", a "non-electric support state" or an "electric support state" is set. The "non-electric support state" is a state in which the game ball enters the second starting port 25 infrequently, and the "electric support state" is a state in which the game ball enters the second starting port 25 in a high frequency. Is. By doing so, in the "non-electric support state", the game ball is more likely to enter the first start port 24 than in the second start port 25, and in the "electric support state", the second start port 24 is easier than the first start port 24. It is easy for the game ball to enter the starting port 25. Therefore, in the "non-electric support state", the player can be made to hit left (to aim at entering the first starting port 24), and in the "electric support state", the player can be made to hit right. It can be done (aiming at the ball entering the second starting port 25).

The segment display unit 50 is provided with an electric support display unit 58 indicating that the segment display unit 50 is in the electric support state described above. That is, as shown in FIG. 4, three LEDs are arranged in the electric support display unit 58, and during the electric support state, the three LEDs are turned on to be in the electric support state. Is shown to the player. Further, the segment display unit 50 is provided with a right-handed display unit 59 that urges the player to perform a right-handed stroke. During the electric support state, the game ball frequently enters the second starting port 25, and the right-handed game ball can enter the second starting port 25. Therefore, the right-handed game ball can enter the second starting port 25. Is beneficial to the player. Therefore, during the electric support state, the player is urged to perform right-handed striking by turning on the two LEDs arranged on the right-handed striking display unit 59.

<Big hit game>
When the CPU 201 of the main control board 200 stops and displays the first special figure or the second special figure with any of the big hit symbols, there are a plurality of round games in which the first special winning opening 28 or the second special winning opening 35 is opened. Start the big hit game that is performed once. As described above with reference to FIG. 2, since a right-handed game ball can enter the first big winning opening 28 and the second big winning opening 35, right-handed hitting is performed during the big hit game. Become.

As shown in FIG. 5, in the pachinko machine 1 of the present embodiment, the big hit game of "V short" and the big hit game of "V long" can be executed as the big hit game. Specifically, as shown in FIG. 5A, when the first special figure is stopped and displayed at the jackpot symbols 101 to 280 (when the first special figure is stopped and displayed at the jackpot symbol, there is a 90% probability. ), When the big hit game of "V short" is performed and the first special figure is stopped and displayed with the big hit symbols 281 to 300 (when the first special figure is stopped and displayed with the big hit symbol, there is a 10% probability. ), "V long" jackpot game is performed. Further, as shown in FIG. 5B, when the second special figure is stopped and displayed at the jackpot symbols 401 to 600 (when the second special figure is stopped and displayed at the jackpot symbol, there is a 100% probability). , "V long" jackpot game is performed.

In the pachinko machine 1 of the present embodiment, regardless of whether the “V short” jackpot game or the “V long” jackpot game is performed, two round games are performed, and the first round game is performed. Then, the first large winning opening 28 is in the open state, and in the second round game, the second large winning opening 35 is in the open state. However, the "V short" jackpot game and the "V long" jackpot game have different "possibility of entering the game ball into the specific mouth 38". That is, in both the "V short" jackpot game and the "V long" jackpot game, the first big winning opening 28 is opened for 10 seconds (or until four game balls enter) in the first round game. Although it is in a state, the opening times of the second large winning opening 35 in the second round game are different from each other. Specifically, in the big hit game of "V short", since the opening time of the second big winning opening 35 in the second round game is 0.2 seconds, it is difficult for the game ball to enter the specific opening 38, and "V". In the "long" jackpot game, since the opening time of the second big winning opening 35 in the second round game is 10 seconds (or until four game balls enter), the game ball enters the specific opening 38. Easy to ball.

Then, as shown in FIG. 5 (c), when the game ball enters the specific mouth 38 during the big hit game of "V short", the game state after the big hit game is "high probability state and electric support state". (High probability / electric support state) ”is set, and if the game ball does not enter the specific mouth 38 during the big hit game of“ V short ”, the game state after the big hit game is“ low probability state and It is set to "non-electric support state (low probability, non-electric support state)".

In addition, when the game ball enters the specific mouth 38 during the big hit game of "V long", the game state after the big hit game is set to "high probability / electric support state", and the big hit of "V long" If the game ball does not enter the specific opening 38 during the game, the game state after the jackpot game ends is set to the "low probability state and electric support state (low probability / electric support state)".

In addition, the "high probability / electric support state" continues until the next big hit game is performed, and the "low probability / electric support state" continues until the symbol variation game is performed 45 times (by then, the big hit game has been performed). If done, it ends).

Here, when starting the big hit game, the CPU 201 of the main control board 200 transmits a big hit game start command indicating that the big hit game is started toward the sub control board 220. Upon receiving the jackpot game start command, the CPU 221 of the sub-control board 220 executes the jackpot game effect corresponding to the jackpot game.

It should be noted that the big hit game (“specification” in the present invention) in which the first big winning opening 28 and the second big winning opening 35 (“variable ball entry opening” in the present invention) are in an open state (“entry possible state” in the present invention). The CPU 201 of the main control board 200 that executes the "game") corresponds to the "specific game execution means" in the present invention.

<Variable display of ordinary symbols, games per ordinary symbols, hold of ordinary symbols>
As described above with reference to FIG. 2, the normal symbol actuating gate 27 allows a right-handed game ball to pass through. When the right-handed game ball passes through the normal symbol operating gate 27 and the game ball is detected by the gate sensor 27s, the CPU 201 of the main control board 200 determines a predetermined determination random number (a random number for determining a normal symbol, which will be described later). Is acquired, and based on the determination random number, a normal map hit determination is performed to determine whether the normal figure is a hit or not. Then, based on the result of this normal symbol hit determination, the normal symbol is displayed in a variable manner and then stopped. As shown in FIG. 4, the segment display unit 50 is provided with a normal figure display unit 56 for displaying a normal symbol, and the normal figure display unit 56 is provided with two LEDs. The normal symbol is variablely displayed by switching the LED that is lit among the two LEDs in the normal figure display unit 56, and is stopped and displayed by setting a predetermined LED among the two LEDs to be lit. In the pachinko machine 1 of the present embodiment, two types of normal symbols, a normal symbol with the left LED lit and a non-regular symbol with the right LED lit, are stopped. It can be displayed. If the result of the normal symbol hit judgment is a normal symbol hit, the normal symbol is stopped and displayed as a normal symbol, and if the result of the normal symbol hit judgment is out of the normal symbol, the normal symbol is stopped and displayed as a normal symbol. Will be done. In this way, when the normal symbol is stopped and displayed as a hit symbol or a missed symbol, a display (confirmation display) is performed in which the stopped display state of the symbol is maintained until a predetermined time elapses in order to confirm the stopped display symbol. Then, when the normal symbol is stopped and displayed as the normal symbol, the normal symbol hit game is performed in which the second start port 25 is closed after the second start port 25 is opened.

The non-electric support state and the electric support state described above are set by different aspects of the normal figure hit determination mode, the normal symbol variation display mode, and the normal figure hit game mode. That is, the probability of being determined to be a normal figure hit in the normal figure hit determination is 1/100 in the non-electric support state and 99/100 in the electric support state. In addition, as the fluctuation time of the normal symbol, a long time is easily selected in the non-electric support state (any of 1000 msec, 2000 msec, and 3000 msec is evenly selected), and a short time is selected in the electric support state. (1000 msec, 1252 msec, 1500 msec is evenly selected). In addition, as a game per normal figure, a game per normal figure is performed in which the second starting port 25 is opened for a short time (16 ms x 1 time) in the non-electric support state, and the second game is performed in the electric support state. A game per game is performed in which the starting port 25 is open for a long time (840 msec x 2 times). As a result, during the non-electric support state, the frequency with which the second starting port 25 is opened is reduced, and the frequency with which the game ball enters the second starting port 25 is also reduced. On the other hand, during the electric support state, the frequency with which the second starting port 25 is opened increases, and the frequency with which the game ball enters the second starting port 25 also increases.

When the game ball passes through the normal symbol operating gate 27, the normal symbol hit determination and the fluctuation display of the normal symbol are performed, but these normal symbol hit determination and the variation display are performed immediately after the game ball passes through the normal symbol operating gate 27. Instead of being performed, the acquired judgment random number is temporarily stored as a normal figure hold. Then, when a predetermined condition is satisfied, the normal figure hit determination and the variation display of the normal symbol are performed based on the stored normal figure hold. Such a normal figure hold is also stored up to a maximum of four. The stored number of the normal figure hold (the number of the normal figure hold) is displayed on the normal figure hold display unit 57 of the segment display unit 50. That is, as shown in FIG. 4, two LEDs are arranged in the normal figure hold display unit 57, and in the normal figure hold display unit 57, both of the two LEDs are turned off to turn off the normal figure. It indicates that the number of holdings is 0, and by turning on one of the two LEDs, it indicates that the number of holdings is 1, and by turning on the two LEDs, it indicates that the number of holdings is 1. It indicates that the number of holdings is 2, and blinking one LED indicates that the number of holdings is 3, and blinking 2 LEDs indicates that the number of holdings is 4. Indicates that there is. In the pachinko machine 1 of the present embodiment, when the holding of the normal symbol is stored, if it is not in the variable display of the normal symbol, the confirmed display of the normal symbol, or the game per normal symbol, it is the first. Judgment of hitting the stored normal figure related to the reserved normal figure and variable display of the normal symbol are performed.

The main control board 200 that performs the processing related to the progress of the game as described above corresponds to the "main control unit" in the present invention.

<Display contents of the effect display device 41>
In the pachinko machine 1 of the present embodiment, various images are displayed on the effect display device 41 in accordance with the progress of the game as described above. The processing for performing such an effect is mainly performed by the CPU 221 of the sub-control board 220. That is, the CPU 221 of the sub control board 220 receives a command indicating the progress of the game (for example, the above-mentioned fluctuation pattern designation command, the jackpot game start command, etc.) from the CPU 201 of the main control board 200. The progress is grasped, and the production is performed according to the progress of this game.

For example, when the CPU 221 of the sub-control board 220 receives the variation pattern designation command, the CPU 221 performs a symbol variation effect according to the variation display (variation pattern) of the first special figure or the second special figure. That is, in synchronization with the start timing of the variation display (symbol variation game) of the special symbol (first special symbol or second special symbol), the effect display device 41 starts the variation display of the three identification symbols 41a, 41b, 41c. To do. After that, the variation display of the identification symbols 41a, 41b, 41c is performed in various modes until the variation time of the special symbol elapses. Then, when the CPU 221 of the sub-control board 220 receives the fluctuation stop command, the symbol variation effect ends. That is, the variation display of the identification symbols 41a, 41b, 41c is terminated in synchronization with the end timing of the variation display of the special symbol (stop display of the special symbol). In the pachinko machine 1 of the present embodiment, it is possible to display a symbol in which nine numbers from "1" to "9" are designed as an identification symbol.

FIG. 6A conceptually shows how the three identification symbols 41a, 41b, and 41c are displayed in a variable manner all at once. When a predetermined time elapses from the start of the variable display, for example, the left identification symbol 41a is first stopped and displayed, then the right identification symbol 41c is stopped and displayed, and finally the middle identification symbol 41b is stopped and displayed. The combination of the three identification symbols 41a, 41b, and 41c that are stopped and displayed on the effect display device 41 is a special symbol that is stopped and displayed on the first special symbol display unit 51 or the second special symbol display unit 52 described above (the first). It is configured to correspond to 1 special figure or 2 special figure). For example, when the first special figure or the second special figure is stopped and displayed with the big hit symbol (that is, when the variation pattern selected when the result of the special figure hit determination is "big hit" is received), The three identification symbols 41a, 41b, 41c of the effect display device 41 are stopped and displayed in a symbol combination (hereinafter, also referred to as “doublet”) having the same symbol. In addition, when the first special figure or the second special figure is stopped and displayed with an out-of-order symbol (that is, when the variation pattern selected when the result of the special figure hit determination is "big hit" is received), The three identification symbols 41a, 41b, and 41c are stopped and displayed in a combination of symbols that are not aligned with the same symbol (hereinafter, also referred to as “separate eyes”). The stop-displayed identification symbols 41a, 41b, and 41c are in a stopped display state (confirmed display) until the final display time of the special symbol elapses.

As described above, the display contents of the special symbol displayed on the first special symbol display unit 51 or the second special symbol display unit 52 and the three identification symbols 41a, 41b, 41c displayed on the effect display device 41 are displayed. They correspond to each other, and when the special symbol in the variable display is stopped and displayed, the three identification symbols 41a, 41b, and 41c are also stopped and displayed. Moreover, as shown in FIG. 2, the effect display device 41 is provided at a position that is more visible than the first special figure display unit 51 or the second special figure display unit 52 (segment display unit 50), and displays the display. Since the screen is large and the display contents are easy to understand, the player usually plays the game while visually recognizing the screen of the effect display device 41. Therefore, as shown in FIG. 6B, for example, the left identification symbol 41a that is first stopped and displayed on the display screen of the effect display device 41 and the right identification symbol 41c that is subsequently stopped and displayed are the same symbol. If there is, the middle identification symbol 41b, which is stopped and displayed at the end, also stops at the same symbol, and the player says, "I think the big hit game will start." ) Will be watched. In this way, the effect performed in a state where the identification symbols other than one of the plurality of identification symbols are stopped at the same symbol (a mode that can be doublet) and the one identification symbol is displayed in a variable manner is ". It is called "reach production", and it is possible to enhance the game entertainment by generating this reach production.

Further, in the lower part of the display screen of the effect display device 41, a first hold display area 41d for showing the number of the first special figure hold and a second hold display area 41e for showing the second special figure hold number. Is set. In the pachinko machine 1 of the present embodiment, the number of the first special figure reserved (small circular symbol in the figure) is displayed in the first reserved display area 41d by displaying the same number of "held symbols (small circular symbols in the figure)" as the number of the first special figure reserved. The upper limit number is 4), and the second special figure hold number is indicated by displaying the same number of "holding symbols" as the second special figure hold number (upper limit number is 4) in the second hold display area 41e. Therefore, in the example shown in FIG. 6, it is shown that the number of the first special figure reserved is four and the number of the second special figure reserved is four. As a matter of course, the number of holds indicated by the hold symbols displayed on the display screen of the effect display device 41, and the first special figure hold display unit 53 and the second special figure hold display unit 54 of the segment display unit 50 Matches the number of holds shown.

The sub-control board 220 that produces the above-mentioned effects according to the progress of the game corresponds to the "sub-control unit" in the present invention.

C. Configuration for detecting fraudulent exchanges:
In the pachinko machine 1 of the present embodiment, the game progresses as described above, but the main control board 200 (“main control unit” in the present invention) that controls the progress of the game is replaced with a non-regular one (so-called). "Unauthorized exchange" may occur). For example, it may be replaced with a main control board that illegally increases the probability that the result of the special figure hit determination will be a "big hit", or a main control board that illegally starts the big hit game when a predetermined operation is performed. .. Then, when the main control board 200 is replaced with a non-regular one in this way, the game hall suffers a great loss. Therefore, the pachinko machine 1 of the present embodiment has a configuration for detecting such "illegal exchange". The configuration will be described below.

C-1. Control circuit for detecting unauthorized exchange:
In addition to the configuration described above with reference to FIG. 3, the pachinko machine 1 of the present embodiment has a configuration as shown in FIG. 7 for detecting unauthorized replacement of the main control board 200. In FIG. 7, the configuration described above with reference to FIG. 3 is omitted as appropriate.

As shown in FIG. 7, the main control board 200 (“main control unit” in the present invention) includes a main flash memory 204 which is a non-volatile storage unit (flash memory) in addition to the CPU 201 and ROM 202. It is installed. The main flash memory 204 stores 4-byte (byte) "first approval data" used for detecting unauthorized replacement of the main control board 200, and the ROM 202 stores the "first approval data". The update program for updating is stored. The CPU 201 reads the "first approval data" from the main flash memory 204, updates the read "first approval data" according to the update program, and stores the updated "first approval data" in the main flash memory 204. ..

Further, the sub-control board 220 (“sub-control unit” in the present invention) is equipped with a sub-side flash memory 224, which is a non-volatile storage unit (flash memory), in addition to the CPU 221 and ROM 222. The sub-side flash memory 224 stores 4-byte (byte) "second approval data" used for detecting unauthorized replacement of the main control board 200, and the ROM 222 stores this "second approval data". The update program for updating is stored. The CPU 221 reads the "second approval data" from the sub-side flash memory 224, updates the read "second approval data" according to the update program, and stores the updated "second approval data" in the sub-side flash memory 224. ..

Here, the update program stored in the ROM 202 of the main control board 200 (that is, the update program for updating the "first approval data") and the update program stored in the ROM 222 of the sub control board 220 (that is, the update program). , The update program for updating the "second approval data") is the same program as each other. Therefore, the "first approval data" and the "second approval data" are updated in the same manner as each other. For example, each time the update process is performed, an operation is performed based on the same function (for example, "1" is added).

The main flash memory 204 that stores the "first approved data" corresponds to the "first storage means" in the present invention, and the sub flash memory 224 that stores the "second approved data" corresponds to the "first storage means" in the present invention. Corresponds to "second storage means".

C-2. Processing to detect fraudulent exchange:
FIG. 8 is a flowchart showing a main-side fraudulent exchange detection process executed by the CPU 201 of the main control board 200. This main control illegal exchange detection process is a process for detecting an illegal exchange of the main control board 200, and is performed at predetermined intervals (for example, based on a timer interrupt generated every 100 msec). When the main side illegal exchange detection process is started, the CPU 201 of the main control board 200 first determines whether or not the "normal command standby flag" is set to ON (S100).

As will be described in detail later, in the pachinko machine 1 of the present embodiment, when detecting an illegal replacement of the main control board 200, the "first approval data" is transmitted from the main control board 200 to the sub control board 220, and the sub The control board 220 determines whether or not the "first approval data" is normal. Then, if the "first approval data" is normal, the "normal command" is transmitted from the sub control board 220 to the main control board 200. The "normal command standby flag" is in a state of waiting for such a "normal command", that is, although the "first approval data" is transmitted to the sub control board 220, the "first approval" is obtained. This flag indicates that the "normal command" corresponding to "data" has not yet been received. Therefore, in the determination process of S100, it is determined whether or not the "normal command" is waiting by determining whether or not the "normal command standby flag" is set to ON. Become. The storage area of the "normal command standby flag" is secured in the RAM 203.

As a result of the determination process of S100, when it is determined that the "normal command wait flag" is OFF, that is, when it is determined that the state is not waiting for the "normal command" (S100: no), the symbol changes. It is determined whether or not the game is being played (during the variable display of the special symbol) (S112). As a result, when the symbol variation game is not in progress (S112: no), the CPU 201 of the main control board 200 reads the "first approval data" from the main flash memory 204 and sub-controls the read "first approval data". It is transmitted toward the substrate 220 (S114). Then, the "normal command standby flag" is set to ON so that the "normal command" corresponding to the transmitted "first approval data" is in the standby state (S116). On the other hand, if it is determined in the determination process of S114 that the symbol variation game is in progress (S114: yes), the "first approval data" is not transmitted (that is, without performing the process related to the illegal exchange). , The main side fraudulent exchange detection process shown in FIG. 8 is terminated as it is. Here, since there is a high possibility that various effects (symbol variation effects) are performed during the symbol variation game, the CPU 201 of the main control board 200 may transmit a command related to the symbol variation effects, and the sub control board 220 may perform a command. The CPU 221 may execute a process related to the symbol variation effect. Therefore, during the symbol variation game, the communication load between the main control board 200 and the sub control board 220 and the processing load of the CPU 201 of the main control board 200 and the CPU 221 of the sub control board 220 may increase. Therefore, the pachinko machine 1 of the present embodiment has a configuration in which the "first approval data" is not transmitted during the symbol variation game (that is, a configuration in which the process for detecting unauthorized replacement of the main control board 200 is not started). As a result, the communication load between the main control board 200 and the sub control board 220, the processing load of the CPU 201 of the main control board 200, and the processing load of the CPU 221 of the sub control board 220 (at least one of these loads) are excessively increased. It suppresses that.

If the "first approval data" is transmitted in the process of S114 and the "normal command wait flag" is set to ON in the process of S116, the "normal command wait flag" is set in the next process of S100 of the main side unauthorized exchange detection process. Is set to ON, that is, it is determined that the state is waiting for a "normal command". When the state is waiting for the "normal command" in this way (S100: yes), it is determined whether or not the "normal command" is received from the sub-control board 220 (S102). As a result, if the "normal command" has not yet been received (S102: no), whether or not the time limit (for example, 0.5 seconds) has elapsed since the "first approval data" was transmitted (so-called timeout). Whether or not it became) is determined (S104). As a result, if the time-out has not yet occurred (S104: no), the main-side unauthorized exchange detection process shown in FIG. 8 is terminated as it is. In this case, in the next main side unauthorized exchange detection process, the process of determining whether or not the "normal command" is received is performed again (S104), and if the "normal command" is not received (S104: no). ), A process of determining whether or not a timeout has occurred is performed (S106).

As a result, when a time-out occurs (S104: yes), that is, when the time limit (for example, 0.5 seconds) elapses without receiving the "normal command" after transmitting the "first approval data". (S104: yes), a time-out handling process for a time-out occurs (S106).

Here, when the time-out occurs, the "first approval data" transmitted to the sub-control board 220 is not normal (for example, the main control board 200 has been illegally replaced), or the sub-control is in the first place. It is assumed that the board 220 (CPU 221 or the like) is not operating normally. Therefore, as the time-out handling process, the control related to the progress of the game of the CPU 201 of the main control board 200 is stopped, or the control of the effect according to the progress of the game of the CPU 221 of the sub control board 220 is stopped (for example). Even if the variation pattern specification command is received, the symbol variation effect is not performed).

However, immediately after the power is turned on to the pachinko machine 1, it takes time to initialize the CPU 221 of the sub-control board 220, and regardless of whether the "first approval data" is normal or not, " It is also assumed that the "normal command" cannot be sent. Until such a case, if the control related to the progress of the game of the CPU 201 of the main control board 200 is stopped, or the control of the effect according to the progress of the game of the CPU 221 of the sub control board 220 is stopped, the pachinko machine 1 Does not work properly. Therefore, when the "first approval data" is transmitted for the first time after the power of the pachinko machine 1 is turned on, the time until the time-out is determined is longer than the above-mentioned time limit (first time) (second time). It may be configured as time), or it may not be determined whether or not the timeout has occurred in the first place. By doing so, it is possible to prevent the pachinko machine 1 from not operating normally as described above.

Further, a person other than the player (for example, a developer) intentionally turns on the power only to the main control board 200 (for example, for performing an operation test), and does not turn on the power to the sub control board 220. Is also assumed. Until such a case, if the control related to the progress of the game of the CPU 201 of the main control board 200 is stopped, or the control of the effect according to the progress of the game of the CPU 221 of the sub control board 220 is stopped, the pachinko machine 1 Does not work properly. Therefore, a test mode (first mode) in which the person concerned intentionally turns on the power only to the main control board 200 (for example, to perform an operation test) and a normal mode (second mode) different from the test mode are provided. , The test mode and the normal mode may be selectively set based on the operation of a person other than the player. Then, when the test mode is set, it may not be determined whether or not the timeout has occurred. By doing so, it is possible to prevent the pachinko machine 1 from not operating normally as described above.

The above has described the process when it is determined that the "normal command" has not been received in the determination process of S102 (S102: no). On the other hand, when it is determined that the "normal command" is being received (S102: yes), first, the "normal command waiting flag" is turned off in order to eliminate the state of waiting for the "normal command". Set (S108). Then, the "first approval data" is read from the main flash memory 204, the read "first approval data" is updated according to the update program stored in the ROM 202 (S110), and the updated "first approval data" is mainly used. Stored in the side flash memory 204.

As described above, when the main control board 200 transmits the "first approval data" and receives the "normal command" indicating that the "first approval data" is normal from the sub control board 220 ("normal"). (Every time a command "is received), the" first approval data "is updated according to the update program.

FIG. 9 is a flowchart showing a sub-side fraudulent exchange detection process executed by the CPU 221 of the sub-control board 220. This sub-side illicit exchange detection process is a process for detecting an illicit exchange of the main control board 200 in response to the above-mentioned main side illicit exchange detection process, and is a timer that occurs every predetermined cycle (for example, every 100 msec). (Based on interrupts). When the sub-side fraudulent exchange detection process is started, the CPU 221 of the sub-control board 220 first determines whether or not the "first approval data" has been received (S200). As a result, when the "first approval data" is received (S200: yes), the "second approval data" is read from the sub-side flash memory 224 and compared with the received "first approval data" ( S202). As a result, if the "first approval data" and the "second approval data" match each other (S204: yes), it is determined that the "first approval data" is normal, and the "normal command" is issued. The data is transmitted to the main control board 200 (S206). Then, the "second approval data" compared with the "first approval data" in the process of S202 is updated according to the update program stored in the ROM 222 (S208), and the updated "second approval data" is updated in the sub-side flash memory 224. To memorize.

Here, in the pachinko machine 1 of the present embodiment, the "first approval data" stored in the main flash memory 204 and the "second approval data" stored in the sub-side flash memory 224 include the pachinko machine 1. At the time of shipment (that is, as an initial value), the same value (for example, "0") is stored in each case. Then, as described above with reference to FIG. 7, the “first approval data” is updated according to the update program each time the main control board 200 receives the “normal command”, and as described above with reference to FIG. The "second approval data" is updated according to the update program every time the sub control board 220 transmits a "normal command". That is, both the "first approval data" and the "second approval data" are updated every time the "normal command" is transmitted / received (every time the "first approval data" is judged to be normal). In other words, the "first approval data" and the "second approval data" are updated based on the same timing (the same number of times). Then, these update programs are the same programs (programs for performing update processing in the same mode). For example, the "first approval data" and the "second approval data" are added (incremented) by "1" each time the update is performed. That is, the "first approval data" and the "second approval data" have the same initial value, and are based on the same timing (the same number of times) and have the same aspect (the "specific aspect" in the present invention. ) Will be updated (according to the update).

Therefore, if the main control board 200 is not illegally replaced, the "first approval data" and the "second approval data" should match each other (the "normal result" in the present invention). On the other hand, if the main control board 200 is illegally replaced, the main flash memory 204 is also replaced naturally, so that the updated "first approval data" is replaced with another value. There is. Therefore, the possibility that the "first approval data" and the "second approval data" match each other is extremely low.

Therefore, as a result of comparing the "first approval data" and the "second approval data" with each other (S202), if they do not match (if the "normal result" in the present invention is not obtained, S204: no), an illegal exchange occurs. Since it can be determined that the data has been performed (the "first approval data" is not normal), the fraudulent exchange handling process corresponding to the fraudulent exchange is performed (S210). For example, the sound indicating that the illegal exchange has been performed is output from various speakers 6a and 6b, and the image indicating that the illegal exchange has been performed is displayed on the display screen of the effect display device 41. Notify that the exchange is taking place. Further, after the illegal exchange is performed, the control of the effect according to the progress of the game of the CPU 221 of the sub control board 220 is stopped (for example, even if the variation pattern designation command is received, the symbol variation effect is not performed. To). Further, a command indicating that the illegal exchange has been performed is transmitted to the main control board 200, and when the CPU 201 of the main control board 200 receives the command, the control related to the progress of the game is stopped.

As described above, in the sub-control board 220, as the "second approval data", when the pachinko machine 1 is shipped (that is, as an initial value), the same value as the "first approval data" (for example, "0"). ") Is remembered. Then, the update of the "second approval data" is performed every time a "normal command" is transmitted / received (based on the same timing as the update of the "first approval data"), similar to the update of the "first approval data". , The update of the "second approval data" is performed in the same manner ("specific mode" in the present invention). Therefore, if the main control board 200 is not illegally replaced, the "first approval data" and the "second approval data" should match each other (the "normal result" in the present invention). On the other hand, if the main control board 200 is illegally replaced, the main flash memory 204 is also replaced naturally, so that the updated "first approval data" is replaced with another value. There is. Therefore, the possibility that the "first approval data" and the "second approval data" match each other is extremely low. Therefore, if the "first approval data" and the "second approval data" do not match each other, it is determined that the main control board 200 has been illegally exchanged, and the illegal exchange response process is performed. As a result, it becomes possible to detect an illegal replacement of the main control board 200 with high accuracy.

FIG. 10 is an explanatory diagram showing collectively the processes for detecting the above-mentioned unauthorized exchange. As shown in FIG. 10, the CPU 201 of the main control board 200 transmits the “first approval data” stored in the main flash memory 204 toward the sub control board 220. When the CPU 221 of the sub control board 220 receives the "first approval data", the CPU 221 compares the "first approval data" with the "second approval data" stored in the sub-side flash memory 224. As a result, when the "first approval data" and the "second approval data" match each other, it is determined that the main control board 200 has not been illegally exchanged (the "first approval data" is normal). Then, a "normal command" is transmitted to the main control board 200. Then, the "second approval data" compared with the "first approval data" is updated according to the update program and stored in the sub-side flash memory 224. When the CPU 201 of the main control board 200 receives the "normal command", the CPU 201 receives the "first approval data" stored in the main flash memory 204 (the "first approval data" transmitted to the sub control board 220). Update according to the update program. Then, the CPU 201 of the main control board 200 and the CPU 221 of the sub control board 220 repeat the above-described processing (the above-mentioned processing using FIGS. 8 and 9).

As described above, the "first approval data" and the "second approval data" have the same initial value, and are based on the same timing (the same number of times) and have the same aspect (the "specific aspect" in the present invention. ") Will be updated (according to the update). Therefore, if the main control board 200 is not illicitly exchanged, the "first approval data" and the "second approval data" should match each other (the "normal result" in the present invention is obtained). On the other hand, if the main control board 200 is illegally replaced, the main flash memory 204 is also replaced naturally, so that the "first approval data" updated up to that point is also replaced with another value. Therefore, the possibility that the "first approval data" and the "second approval data" match each other is extremely low. Therefore, if the "first approval data" and the "second approval data" do not match each other, it is determined that the main control board 200 has been illegally exchanged, and the illegal exchange response process is performed. As a result, it becomes possible to detect an illegal replacement of the main control board 200 with high accuracy.

Here, it is assumed that the illegal replacement of the main control board 200 is performed after the power of the pachinko machine 1 is turned off (when the power is not supplied to the pachinko machine 1). In this respect, in the pachinko machine 1 of the present embodiment, the "first approved data" is stored in the main flash memory 204 which is the non-volatile storage unit, and the "second approved data" is stored in the non-volatile storage unit. It is stored in a certain sub-side flash memory 224. Therefore, even if the power of the pachinko machine 1 is turned off, the values of the "first approval data" and the "second approval data" before the power of the pachinko machine 1 is turned off are retained. Then, when the power of the pachinko machine 1 is turned on after that, the values held as the "first approval data" and the "second approval data" are updated to detect the illegal exchange described above. Processing will be performed. When the main control board 200 is illegally replaced after the power of the pachinko machine 1 is turned off, the main flash memory 204 is also replaced naturally, so that the value held as the "first approval data" is obtained. Will be replaced with another value, and there is a high possibility that the "first approval data" and the "second approval data" will not match each other. As a result, even when the illicit replacement of the main control board 200 is performed after the power of the pachinko machine 1 is turned off, the illicit replacement can be detected with high accuracy.

Further, in the pachinko machine 1 of the present embodiment, as a part of the illegal exchange handling process, the CPU 221 of the sub control board 220 stops the control of the effect according to the progress of the game (for example, even if a variation pattern designation command is received). , Do not perform pattern fluctuation production). Most players keep track of the progress of the game based on the production that matches the progress of the game, and there is a high possibility that those who attempt fraudulent exchange will do so. Therefore, as a result of illegally exchanging the main control board 200, if the effect according to the progress of the game is not performed, the person who performed the illegal exchange cannot grasp the progress of the game and intends to play the game. It becomes difficult to proceed in a targeted manner. As a result, it is possible to prevent the game hole from suffering a loss. Further, in recent years, a flashy production is often performed as a production according to the progress of the game, but the pachinko machine 1 in which such a flashy production is no longer performed becomes conspicuous. As a result, it becomes easier to detect unauthorized replacement of the main control board 200.

Further, in the pachinko machine 1 of the present embodiment, the CPU 201 of the main control board 200 stops the control related to the progress of the game as a part of the illegal exchange handling process. When the control related to the progress of the game is stopped in this way, the progress of the game is not performed thereafter, and by extension, the game ball is not paid out. As a result, it becomes easier to detect an illegal replacement of the main control board 200, and by extension, it becomes possible to suppress the game hole from suffering a loss.

Further, when the main control board 200 is illegally replaced, the game hall often suffers a loss due to the illegal performance of the specific game. In this regard, in the pachinko machine 1 of the present embodiment, when the special symbol is displayed as the jackpot symbol, the jackpot game is performed, but when such a variable display of the special symbol is performed (start of the variable display of the special symbol). (At the timing), the "first approval data" and the "second approval data" are compared with each other. That is, when the possibility that the big hit game is performed increases, the "first approval data" and the "second approval data" are compared with each other to determine whether or not the main control board 200 has been illegally exchanged. (Discover unauthorized replacement of the main control unit). As a result, it is possible to prevent the game hole from suffering a loss.

The "normal command" corresponds to the "normal signal" in the present invention, and the "first approved data" stored in the main flash memory 204 (first storage means) is updated (in a specific mode) according to the update program. The CPU 201 of the main control board 200 corresponds to the "first updating means" in the present invention. Further, the CPU 201 of the main control board 200 that transmits the "first approval data" stored in the main flash memory 204 (first storage means) to the sub control board 220 (sub control unit) is in the present invention. Corresponds to the "first transmission means". Further, the CPU 201 of the main control board 200 that compares the "first approval data" with the "second approval data" stored in the sub-side flash memory 224 (second storage means) is the "comparison means" in the present invention. Corresponds to. Further, when the "first approval data" and the "second approval data" match each other (when a normal result is obtained), a "normal command (normal signal)" is sent to the main control board 200 (main control unit). The CPU 221 of the sub-control board 220 that transmits toward the sub-control board 220 corresponds to the "second transmission means" in the present invention. Further, when the "first approval data" and the "second approval data" match each other (when a normal result is obtained), the "second" stored in the sub-side flash memory 224 (second storage means). The CPU 221 of the sub-control board 220 that updates the "approval data" according to the update program (in a specific mode) corresponds to the "second update means" in the present invention. Further, when the "first approval data" and the "second approval data" do not match each other (when the normal result is not obtained), the sub control board 220 notifies that the main control board 200 has been illegally replaced. CPU 221 corresponds to the "notifying means" in the present invention.

D. Modification example:
In the above-described embodiment, the timing at which the main control board 200 transmits the “first approval data” to the sub control board 220, that is, the “first approval data” and the “second approval data” are compared with each other. The timing may be as follows. For example, when the front frame 4 is closed after being opened, or when the middle frame is closed after being opened (when a predetermined comparison condition is satisfied), the "first approval data" and the "second" Approval data may be compared with each other. Here, the illegal replacement of the main control board 200 is often performed by opening the front frame 4 and the middle frame. Therefore, when the front frame 4 is closed after being opened, or when the middle frame is closed after being opened, the "first approval data" and the "second approval data" are compared with each other. It is possible to determine whether or not the illicit exchange has been performed at the timing when the illicit exchange of the main control board 200 has been performed, and by extension, the same illicit exchange response process as in the embodiment can be performed at this timing. As a result, it is possible to prevent the game hole from suffering a loss.

Further, when the jackpot game (specific game) is started, that is, when the jackpot game start command is transmitted to the sub control board 220 (when a predetermined comparison condition is satisfied), "first approval". The "data" and the "second approval data" may be compared with each other. Here, the illegal exchange of the main control board 200 is performed for the purpose of illegally paying out the game ball. The payout of such a game ball is performed through a jackpot game. Therefore, when the big hit game is started, if the "first approval data" and the "second approval data" are compared with each other, at the timing when the game ball is illegally paid out due to the illegal exchange of the main control board 200. It is possible to determine whether or not the fraudulent exchange has been performed, and by extension, the fraudulent exchange handling process similar to that of the embodiment can be performed at this timing. As a result, it is possible to prevent the game hole from suffering a loss.

Further, when the game ball is paid out, that is, when the payout command is transmitted to the payout control board 240 (when a predetermined comparison condition is satisfied), the "first approval data" and the "second approval data" And may be compared with each other. Here, the illegal exchange of the main control board 200 is performed for the purpose of illegally paying out the game ball. Therefore, when the game ball is paid out, if the "first approval data" and the "second approval data" are compared with each other, the game ball is illegally paid out at the timing when the main control board 200 is illegally exchanged. It is possible to determine whether or not the fraudulent exchange has been performed, and by extension, the fraudulent exchange handling process similar to that of the embodiment can be performed at this timing. As a result, it is possible to prevent the game hole from suffering a loss.

Although examples and modifications of the present invention have been described above, the present invention is not limited to this, and is not limited to the wording of each claim as long as it does not deviate from the scope described in each claim. It extends to the extent that those skilled in the art can easily replace them, and improvements based on the knowledge normally possessed by those skilled in the art can be added as appropriate.

For example, in the above-described examples and modifications, when the "first approval data" and the "second approval data" match each other, it is determined that the main control board 200 has not been illegally replaced. did. That is, the result in which the "first approval data" and the "second approval data" match each other is defined as the "normal result" in the present invention. Not limited to this, when the "first approval data" and the "second approval data" do not match each other, it is determined that the main control board 200 has not been illegally replaced (the "normal result" in the present invention is used. ) May occur. For example, when the initial values of the "first approval data" and the "second approval data" are different from each other, the result of comparing the "first approval data" and the "second approval data" with each other is the difference between the initial values. When the result is considered, it is determined that the illegal exchange has not been performed (referred to as the "normal result" in the present invention). For example, the initial value of the "first approval data" is "0", the initial value of the "second approval data" is "10", and the update processing of the "first approval data" and the "second approval data". When is a mode in which is added one by one, the result of comparing the "first approval data" and the "second approval data" with each other is that the "second approval data" is "10" larger than the "first approval data". When the result is obtained, it is determined that the main control board 200 has not been illegally replaced (referred to as the "normal result" in the present invention).

In the above-described embodiment and modification, if the time limit (for example, 0.5 seconds) elapses without receiving the "normal command" after the "first approval data" is transmitted, the timeout handling process is performed. However, not limited to this, if the time limit (for example, 0.5 seconds) elapses without receiving the "normal command" after sending the "first approval data", the same "first approval data" is sent again. 1 Approval data ”may be transmitted. In this way, even if the communication line (for example, harness) between the main control board 200 and the sub control board 220 is not connected and the communication line is connected after that, the communication line is connected. After that, the sub control board 220 receives the "first approval data" and performs the process for detecting the illegal exchange as described above, so that the illegal exchange of the main control board 200 can be detected with high accuracy. It will be possible. Further, even when the power is not supplied to the sub control board 220 and the power is supplied after that, the sub control board 220 receives the "first approval data" after the power is supplied. Then, since the process for detecting the illegal exchange as described above is performed, it is possible to detect the illegal exchange of the main control board 200 with high accuracy.

Further, in the above-described examples and modifications, the present invention is applied to the pachinko machine 1 that plays a game by firing a game ball toward the game area 21 formed on the game board 20, but there are a plurality of types on the outer peripheral surface. The present invention may be applied to a slot machine (rotating machine) in which a game is performed by rotating a rotating cylinder on which the pattern of the above pattern is drawn and stopping the rotating cylinder.

Further, in the above-described embodiment and modification, the present invention relates to the pachinko machine 1 that gives a player a profit (game value) as a result of the game by paying out the game ball supplied from the island equipment of the game hall. An example of applying The present invention is not limited to this, and the present invention can be applied to a game machine of a type in which a game benefit is given in a form different from the “painment of game balls”. For example, when a game ball enters various entrances, data indicating the amount of profit (magnitude of game value) corresponding to the entry is stored, thereby providing a profit (game) in the game. The present invention can be applied to a pachinko machine of a type that imparts a value) to a player, and in this case as well, the same effect as that of the above-described embodiment can be obtained. As a type of pachinko machine that converts game benefits (game value) into data and gives it to the player, a game machine that circulates and uses a plurality of game balls built in the pachinko machine, specifically An example is a pachinko machine (so-called enclosed game machine) configured to return a game ball discharged to the back surface of the game board through various entrances or out ports and fire it again.
Further, the pachinko machine of the above-described embodiment or modified example can be grasped as the following gaming machine. That is,
<Grasp example 1>
In a gaming machine including a main control unit that controls the progress of a game and a sub control unit that controls an effect according to the progress of the game.
The main control unit
The first storage means for storing the first approval data and
Each time a normal signal is received from the sub-control unit, the first update means for updating the first approval data stored in the first storage means in a specific mode, and
A first transmission means for transmitting the first approval data stored in the first storage means to the sub-control unit, and a first transmission means.
With
The sub-control unit
A second storage means for storing the second approval data,
Each time the first approval data is received from the main control unit, a comparison means for comparing the first approval data with the second approval data stored in the second storage means, and a comparison means.
When the result of the comparison by the comparison means is a normal result, the second transmission means for transmitting the normal signal toward the main control unit and the second transmission means.
When the result of the comparison by the comparison means becomes a normal result, the second update means for updating the second approval data stored in the second storage means in the specific mode, and the second update means.
When the result of the comparison by the comparison means is not the normal result, the notification means for notifying that the fraud has been performed and the notification means.
A gaming machine characterized by being equipped with.
In such a gaming machine, when the comparison result between the first approval data and the second approval data is a normal result (when transmitting and receiving a normal signal), the main control unit updates the first approval data and subordinates it. Since the control unit updates the second approval data, only one of the first approval data and the second approval data is not updated. For example, when the power is turned on to only one of the main control unit and the sub control unit, or when the power harness is not connected, only one of the first approval data and the second approval data is updated. There is no. That is, since the first approval data and the second approval data are updated only based on the same timing, the first approval data unless the main control unit is illegally exchanged (so-called illegal exchange is not performed). The comparison result between the second approval data and the second approval data is a normal result (planned result, for example, the same value). On the other hand, if the main control unit is illegally exchanged, the first approval data becomes the data stored in the first storage means of the main control unit that has been illegally exchanged. That is, the data is different from the normal first approval data that has been continuously updated before the unauthorized exchange. Therefore, the comparison result between the first approval data and the second approval data is not a normal result, and a notification suggesting that fraud has been performed is performed. As a result, it becomes possible to detect an illegal exchange of the main control unit with high accuracy.
<Grasp example 2>
Also, with these gaming machines,
The main control unit
Identification information display means for variable display of identification information,
Based on the identification information being displayed in a specific mode, a specific game execution means for executing a specific game in which the variable entrance is in a ball-entry state, and a specific game execution means.
With
While the identification information is displayed in a variable manner by the identification information display means, the first transmission means may not transmit the first approval data to the sub-control unit.
In such a gaming machine, since the process of transmitting the first approval data from the main control unit to the sub control unit is not performed during the variable display of the identification information, the above-mentioned process following this process is not performed. That is, during the variable display of the identification information, the process for detecting the illegal exchange of the main control unit described above is not started. Here, in a general gaming machine, there is a high possibility that various effects will be performed during the variable display of the identification information, so that various signals may be transmitted and received between the main control unit and the sub control unit. As a result, the possibility that various processes are executed in the main control unit and the sub control unit increases. In this respect, the gaming machine of the present invention does not start the process for detecting the illegal exchange of the main control unit described above during the variable display of the identification information, so that the communication load between the main control unit and the sub control unit and the communication load between the main control unit and the sub control unit are increased. It is possible to suppress an excessive increase in the processing load of the main control unit and the processing load of the sub control unit (at least one of these loads).
<Grasp example 3>
Also, with these gaming machines,
If the result of the comparison by the comparison means is not the normal result, the main control unit may stop the control of the progress of the game.
In such a gaming machine, if it is determined that the main control unit has been illegally exchanged, the game does not proceed thereafter, and the gaming medium is not paid out. As a result, it becomes easier to detect unauthorized replacement of the main control unit, and by extension, it becomes possible to suppress the game hall from suffering a loss.
<Grasp example 4>
Also, with these gaming machines,
If the result of the comparison by the comparison means is not the normal result, the sub-control unit may stop the control of the effect.
In such a gaming machine, if it is determined that the main control unit has been illegally exchanged, the production is not performed according to the progress of the gaming thereafter. Most players keep track of the progress of the game based on the production that matches the progress of the game, and there is a high possibility that those who attempt fraudulent exchange will do so. Therefore, as a result of the illegal exchange of the main control unit, if the production according to the progress of the game is not performed, the person who performed the illegal exchange cannot grasp the progress of the game, and the game is intentionally performed. It becomes difficult to proceed to. As a result, it is possible to prevent the game hole from suffering a loss. Further, in recent years, flashy productions are often performed as productions that match the progress of the game, but gaming machines that do not perform such flashy productions are conspicuous. As a result, it becomes easier to detect an illegal exchange of the main control unit.

The present invention can be used for a gaming machine used in a gaming hall.
