The AMP amplifies the sound signal and generates sound from the speaker 21.

  The lamp control circuit 80 includes a drive circuit for supplying a lamp control signal, a decoration data ROM in which a plurality of types of lamp decoration patterns are stored, and the like.

[Game machine operation]
Hereinafter, processing executed by the main control circuit 55 of the ball game machine 1 will be described with reference to FIGS. The processing executed by the sub control circuit 56 will be described with reference to FIGS. Hereinafter, each process executed by the main control circuit 55 and the sub control circuit 56 will be described for each item with a subtitle.

[Main processing]

Although the details will be described later with reference to FIG. 8, in the next step S111, the main CPU 31 causes the special symbol game to progress, the special symbols displayed on the liquid crystal display device 5 and the special symbol display device 18, and the special symbols related to the decorative symbols. Execute control processing.

  Then, as will be described in detail later with reference to FIG. 10, in the next step S112, the main CPU 31 executes normal symbol control processing relating to the progress of the normal symbol game and the normal symbols displayed on the normal symbol display device 19. In the next step S113, the main CPU 31 executes a symbol display device control process for performing display control of variable display such as a special symbol and a normal symbol in accordance with the execution result of the special symbol control process and the normal symbol control process.

  In the next step S114, the main CPU 31 obtains the number of game balls won in the big prize opening 85 stored in the main RAM 33 based on the detection signal from the count sensor 85S and the number of game balls stored in the main ROM 32. By comparing, an illegal sphere check process for determining the presence or absence of an illegal act is executed. The game ball number information stored in the main ROM 32 is game ball number information that serves as a criterion for fraud in each game state in a plurality of special game states and game states other than the special game state. The details will be described in the explanation of the illegal sphere check process.

  In this way, in the main process, after the initial setting process is completed, the special symbol control process, the normal symbol control process, the symbol display device control process, and the illegal ball check process are repeatedly executed.

[System timer interrupt processing]
Even when the main CPU 31 is executing the main process, the main CPU 31 may interrupt the main process and execute the system timer interrupt process. The following system timer interrupt process is executed in response to a clock pulse generated every predetermined period (for example, 2 milliseconds) from the reset clock pulse generation circuit 34. This system timer interrupt process will be described with reference to FIG.

  As shown in FIG. 7, in the first step S120, the main CPU 31 executes a random number update process so as to increase the count values of the big hit determination random number counter, the big hit symbol determination random number counter, etc. by “1”. In the next step S121, the main CPU 31 executes an input detection process for detecting the winning or passing of the game ball to the start port 83 or the like.

  In the next step S122, the main CPU 31 waits for a synchronization between the main control circuit 55 and the sub-control circuit 56, a waiting time timer for counting the opening time of the big winning opening 85, and a big winning opening opening time timer. Various timer update processes such as (a timer corresponding to the driving time of the special electric accessory) are executed.

In the next step S124, the main CPU 31 executes command output processing for supplying various commands to the sub-control circuit 56.

  In the next step S125, the main CPU 31 executes a payout process such as transmitting a prize ball control command for causing the payout device 43 to play a prize ball to the payout / firing control circuit 44. When this process is finished, this subroutine is finished, the address is returned to the address before the occurrence of the interrupt, and the main process is executed.

[Special symbol control processing]
The special symbol control process shown in step S111 of FIG. 6 will be described with reference to FIG. In FIG. 8, the numerical value drawn on the side of each process indicates a control state flag corresponding to each process, and one step corresponding to the numerical value is executed according to the numerical value of the control state flag. The special symbol game will proceed.

  First, in step S130 of FIG. 8, the main CPU 31 executes processing for loading a control state flag. In each process described later, the main CPU 31 determines whether or not to execute various processes in each step based on the value of the control state flag. This control state flag indicates the game state of the special symbol game, and allows any one of the processes to be executed. In addition, the main CPU 31 executes processing in each step at a predetermined timing determined according to a waiting time timer or the like set for each step.

  Before reaching the predetermined timing, the process ends without executing the process in each step, and another subroutine is executed. Of course, the system timer interrupt process is also executed at a predetermined cycle.

  In the next step S131, the main CPU 31 executes a special symbol storage check process. Although the details will be described later with reference to FIG. 9, the main CPU 31 checks the number of reserved pieces when the control state flag is a value (00) indicating the special symbol storage check process. Judgment, determination of derived special symbols, variation pattern of special symbols, etc.

  Then, the main CPU 31 sets the value (01) indicating the special symbol variation time management process in the control state flag, and sets the variation time corresponding to the variation pattern determined in the current process in the waiting time timer. In other words, after the variation time corresponding to the variation pattern determined this time has elapsed, the special symbol variation time management process described later is set to be executed. On the other hand, when there is no reserved number, the main CPU 31 performs a demonstration display process for displaying a demonstration screen.

  In the next step S132, the main CPU 31 executes a special symbol variation time management process. In this process, the main CPU 31 sets the control state flag to a value (01) indicating the special symbol change time management process, and when the change time has elapsed, the main CPU 31 sets the value (02) indicating the special symbol display time management process to the control state. Set to flag and set wait time after set to wait time timer. In other words, after the waiting time after the determination, the special symbol display time management process described later is set to be executed.

  In the next step S133, the main CPU 31 executes a special symbol display time management process. In this process, the main CPU 31 determines that the control state flag is a value (02) indicating the special symbol display time management process, and if the waiting time after the determination has elapsed, two rounds (2R) of big hit (first special gaming state) ) Or 15 rounds (15R) of big hit (second special gaming state). When the main CPU 31 determines that it is one of the big hits, it sets a value (03) indicating the big hit start interval management process in the control state flag, and sets the time corresponding to the big hit start interval management process as a waiting time timer. Set to. That is, after the time corresponding to the big hit start interval management process elapses, the big hit start interval management process described later is set to be executed.

  On the other hand, when the main CPU 31 determines that it is not a big hit, it sets a value (08) indicating a special symbol game end process. That is, the special symbol game end process described later is set to be executed.

  If the main CPU 31 determines that it is a big hit, it executes a big hit start interval management process in the next step S134. In this process, the main CPU 31 closed the big prize opening 85 when the control state flag is a value (03) indicating the big hit start interval management process and the time corresponding to the big hit start interval management process has elapsed. In order to open the shutter 86, the variables positioned in the main RAM 33 are updated based on the data read from the main ROM 32. The main CPU 31 sets a value (04) indicating that the big prize opening 85 is being opened to the control state flag, and the upper limit time for opening the big prize opening 85 corresponding to each big hit such as 2R or 15R. (For example, 30 seconds for 15R jackpot, 1 second for 2R jackpot) is set in the big prize opening time timer. Then, the value of the big winning opening opening number counter corresponding to each big hit such as 2R or 15R (for example, 15 times for 15R big hit and 15 times for driving for 2R big hit) is set. That is, in the next step S135, it is set to execute the special winning opening opening process.

  In step S135, the main CPU 31 executes a special winning opening opening process. In this process, when the control state flag is a value (04) indicating that the big prize opening is being opened, the main CPU 31 opens the big prize opening 85 under the condition that the big prize opening prize counter is a predetermined number or more. It is determined whether or not any of the conditions that the upper limit time to be passed has passed (the big winning opening opening time timer is “0”) is satisfied (a predetermined closing condition is satisfied).

  The main CPU 31 updates a variable positioned in the main RAM 33 in order to close the special winning opening 85 when any of the above-described conditions is satisfied. Then, the main CPU 31 sets a value (05) indicating the special winning opening residual ball monitoring process to the control state flag. The main CPU 31 sets the winning ball remaining ball monitoring time in the waiting time timer. In other words, after the time for monitoring the remaining balls in the big prize opening has elapsed, it is set to execute the monitoring process for the residual balls in the big prize mouth described later.

  Then, at the next step S136, the main CPU 31 executes a special winning opening residual ball monitoring process. In this process, the main CPU 31 has a value (05) indicating that the control state flag indicates the winning ball remaining ball monitoring process, and when the winning ball remaining ball monitoring time elapses, the main winning port opening number counter is set to the big winning. It is determined whether or not the condition that the number of mouth opening times is equal to or greater than the maximum value (the final round) is satisfied.

  When this condition is satisfied, the main CPU 31 sets a value (07) indicating the big hit end interval process in the control state flag, and sets a time corresponding to the big hit end interval process in the waiting time timer. That is, after the time corresponding to the big hit end interval process elapses, each of the big hit end interval process described later is set to be executed.

  On the other hand, when this condition is not satisfied, the main CPU 31 sets a value (06) indicating the waiting time management process before reopening the big winning opening in the control state flag. Further, the main CPU 31 sets a time corresponding to the interval between rounds in the waiting time timer. In other words, after the time corresponding to the interval between rounds has elapsed, the waiting time management process before reopening the big winning opening described later is set to be executed.

  If the main CPU 31 determines that the special prize opening number counter is not equal to or greater than the maximum value of the special prize opening number, the main CPU 31 proceeds to step S137 and executes the waiting time management process before the special prize opening reopening. In this process, the main CPU 31 has a value (06) indicating that the control state flag indicates the waiting time management process before reopening the big winning opening, and the time corresponding to the interval between rounds has elapsed, The counter is updated so that the counter is incremented by “1”. The main CPU 31 sets a value (04) indicating that the special winning opening is being opened in the control state flag. The main CPU 31 sets an upper limit time (for example, 30 seconds) for opening the special winning opening 85 to the special winning opening opening timer. That is, the above-described process for opening the special winning opening is set to be executed again.

  Then, when the main CPU 31 determines that the big prize opening number counter is equal to or larger than the maximum value of the big prize opening number, the main CPU 31 proceeds to step S138 and executes the big hit end interval process. In this process, the main CPU 31 has a value (07) indicating that the control state flag indicates the jackpot end interval process, and when the time corresponding to the jackpot end interval process has elapsed, a value (08) indicating the special symbol game end process. Is set in the control status flag. That is, the special symbol game end process described later is set to be executed.

  The main CPU 31 performs control to shift to a probability variation state when the big hit symbol is a probability variation symbol, and performs control to shift to the normal gaming state when the big hit symbol is a non-probability variation symbol. Become.

  Then, when the big hit gaming state is finished or lost, the main CPU 31 proceeds to step S139 to execute a special symbol game ending process. In this process, when the control state flag is a value (08) indicating the special symbol game end process, the main CPU 31 stores and updates the data indicating the number of holdings (starting storage information) so as to decrease by “1”. Then, the main CPU 31 updates the special symbol storage area in order to perform the next fluctuation display. The main CPU 31 sets a value (00) indicating the special symbol storage check process. That is, the special symbol storage check process described above is set to be executed. When this process is finished, this subroutine is finished.

  As described above, the special symbol game is executed by setting the control state flag. Specifically, the main CPU 31 sets the control state flags in order of (00), (01), (02), and (08) when the result of the big hit determination is lost in the case of not being in the big hit gaming state. Thus, the special symbol memory check process, the special symbol variation time management process, the special symbol display time management process, and the special symbol game end process shown in FIG. 8 are executed at a predetermined timing.

  Further, when the main CPU 31 is not in the big hit gaming state and the result of the big hit determination is a big hit, the main CPU 31 sets the control state flags in order of (00), (01), (02), (03), The special symbol memory check process, the special symbol variation time management process, the special symbol display time management process, and the big hit start interval management process shown in FIG. 8 are executed at a predetermined timing, and the control to the big hit gaming state is executed.

  Further, when the control to the big hit gaming state is executed, the main CPU 31 sets the control state flags in order of (04), (05), and (06), thereby opening the big winning opening shown in FIG. The middle processing, the winning ball residual ball monitoring processing, and the waiting time management processing before reopening the big winning port are executed at a predetermined timing, and the big hit game is executed.

  When the big hit game is executed and the end condition for the big hit game state is satisfied, (04), (05), (07), and (08) are set in this order, so that FIG. The big prize opening opening process, the big prize opening residual ball monitoring process, the big hit end interval process, and the special symbol game end process are executed at predetermined timings, and the big hit gaming state is ended.

[Special symbol memory check processing]
The special symbol memory check process shown in step S131 of FIG. 8 will be described with reference to FIG. FIG. 9 is a flowchart for explaining the special symbol storage check process when there are a plurality of types of jackpots. FIG. 9 shows an embodiment of the ball game machine 1 in which a jackpot of 15 rounds and a jackpot of two rounds executed in the jackpot gaming state are provided side by side. The present invention is not limited to the ball and ball game machine 1 having various types of jackpot game states, and can be applied to a ball and ball game machine having three or more types of jackpot game states.

  In step S210 shown in FIG. 9, the main CPU 31 determines whether or not the control state flag is a value (00) indicating the special symbol storage check process. When the main CPU 31 determines that the control state flag is a value indicating the special symbol storage check process, the main CPU 31 proceeds to step S211 and determines whether or not the number of holds is “0”. On the other hand, when the main CPU 31 does not determine that the control state flag is a value indicating the special symbol storage check process, the main CPU 31 ends the present subroutine.

  If the main CPU 31 determines in step S211 that the data indicating the number of holds is “0”, the main CPU 31 proceeds to step S212 and executes a demo display process. When the process in step S212 is finished, this subroutine is finished.

  On the other hand, if the main CPU 31 does not determine in step S211 that the data indicating the number of reservations is “0”, the process proceeds to step S213, where a value indicating the special symbol variation time management process (step S213). 01) is executed.

  Then, the process proceeds to the next step S214, and the main CPU 31 performs a jackpot determination process, and determines whether or not the 15R jackpot is based on the extracted random number value and the 15R jackpot determination table. In this process, the main CPU 31 reads the high probability flag, and selects one jackpot determination table from a plurality of jackpot determination tables having different numbers of jackpot determination values based on the read high probability flag.

  As described above, when the high probability flag is a predetermined value, that is, when the gaming state is in a probable variation state, the probability of shifting to the big hit gaming state is improved as compared with the normal time. Then, the process proceeds to the next step S215, and the main CPU 31 (lottery means) has 15 rounds (15R) that are advantageous to the player based on the jackpot determination random number extracted at the time of starting winning and the selected jackpot determination table. ) It is determined whether or not the big hit gaming state is set.

  If it is determined in step S215 that the big hit gaming state is set, the processing executed by the main CPU 31 proceeds to step S216, and the processing for setting the 15 round (15R) big hit flag to ON is executed. When the process in step S216 ends, the process proceeds to step S220, and the main CPU 31 executes a special symbol determination process. On the other hand, if it is not determined in step S215 that the jackpot gaming state is set, the process proceeds to step S217.

  In step S217, the main CPU 31 performs a jackpot determination process, and determines whether or not the 2R jackpot is based on the extracted random number value and the 2R jackpot determination table. In this process, the main CPU 31 reads the high probability flag, and selects one jackpot determination table from a plurality of jackpot determination tables having different numbers of jackpot determination values based on the read high probability flag.

  Next, the process proceeds to step S218, and the main CPU 31 (lottery means) makes a two-round (2R) jackpot gaming state based on the jackpot determination random number extracted at the time of starting winning and the selected jackpot determination table. It will be determined whether or not.

  If it is determined in step S218 that the 2-round (2R) jackpot gaming state is set, the process proceeds to step S219, and processing for setting the 2-round (2R) jackpot flag to ON is executed. And it progresses to step S220 and a special symbol determination process is performed.

  On the other hand, if it is not determined in step S218 that the two round (2R) jackpot gaming state is set, the process proceeds to step S220, and the special symbol determination process is executed.

  Then, the main CPU 31 executes a special symbol determination process in step S220. In this process, the main CPU 31 (random number extraction means) reads the jackpot symbol random number value extracted at the time of starting winning, and based on the jackpot symbol random number value and the result of the 2R or 15R jackpot determination described above, the special symbol The data indicating the special symbol is stored in a predetermined area of the main RAM 33. In addition, when determining the special symbol as a special display mode (a display mode in which the jackpot symbol becomes a probable variation symbol), the main CPU 31 performs control for shifting to the probable variation state.

  The data indicating the special symbol stored in this way is supplied to the special symbol display device 18. As a result, the special symbol is derived and displayed on the special symbol display device 18. Further, the data indicating the special symbol stored in this way is supplied from the main CPU 31 of the main control circuit 55 to the sub CPU 61 of the sub control circuit 56 as a derived symbol designation command. As a result, the decorative design corresponding to the special design is derived and displayed on the liquid crystal display device 5 in the sub control circuit 56.

  In the next step S221, the main CPU 31 executes a variation pattern determination process. In this process, the main CPU 31 extracts a rendering condition selection random value. The main CPU 31 selects a variation pattern distribution table for determining a variation pattern based on the special symbol determined as described above. The main CPU 31 determines a variation pattern based on the rendering condition selection random number extracted from the rendering condition selection random number counter and the selected variation pattern distribution table, and stores the variation pattern in a predetermined area of the main RAM 33. The main CPU 31 determines the variation display mode (in particular, the variation display time) of the special symbol based on the data indicating such a variation pattern.

  The data indicating the variation pattern stored in this way is supplied to the special symbol display device 18. As a result, the special symbol display device 18 variably displays the variation pattern determined by the special symbol. Further, the data indicating the variation pattern stored in this way is supplied from the main CPU 31 of the main control circuit 55 to the sub CPU 61 of the sub control circuit 56 as a variation pattern designation command. The sub CPU 61 of the sub control circuit 56 executes an effect display according to the received variation pattern designation command.

  Then, in the next step S222, the main CPU 31 executes a process for setting the variation time in the waiting time timer according to the determined variation pattern. In the next step S223, processing for clearing the storage area used for the current variation display is executed. When this process is finished, this subroutine is finished.

[Normal symbol control processing]
The normal symbol control process shown in FIG. 6 will be described with reference to FIG. In FIG. 10, the numerical value drawn on the side of each process indicates a normal symbol control state flag corresponding to those steps, and one numerical value corresponding to the numerical value of the normal symbol control state flag corresponds to that numerical value. Steps are executed and the normal symbol game proceeds.

  First, in step S250, the main CPU 31 executes processing for loading the normal symbol control state flag. In this process, the main CPU 31 reads the normal symbol control state flag.

  In the process described later, the main CPU 31 determines whether or not to execute various processes in each step based on the value of the normal symbol control state flag. The normal symbol control state flag indicates the game state of the normal symbol game, and enables one of the processes to be executed. In addition, the main CPU 31 executes processing in each step at a predetermined timing determined according to a waiting time timer or the like set for each step.

  Before reaching the predetermined timing, the process ends without executing the process in each step, and another subroutine is executed. Of course, the system timer interrupt process is also executed at a predetermined cycle.

  In step S251, the main CPU 31 executes normal symbol memory check processing. In this process, when the normal symbol control state flag is a value (00) indicating the normal symbol storage check process, the main CPU 31 checks the number of reserved symbols related to the normal symbol. I do. Then, the main CPU 31 sets the value (01) indicating the normal symbol variation time management process in the normal symbol control state flag, and sets the variation time determined in this process in the waiting time timer. In other words, after the variation time determined this time has elapsed, the normal symbol variation time monitoring process described later is set to be executed.

  In step S252, the main CPU 31 executes normal symbol variation time monitoring processing. In this process, the main CPU 31 has a value (01) indicating that the normal symbol control state flag indicates the normal symbol variation time management process, and a value (02) indicating the normal symbol display time monitoring process when the variation time has elapsed. The normal symbol control state flag is set, and the waiting time after determination (for example, 0.5 seconds) is set in the waiting time timer. That is, after the waiting time after the determination, the normal symbol display time monitoring process described later is set to be executed.

  In step S253, the main CPU 31 executes normal symbol display time monitoring processing. In this process, the main CPU 31 determines whether or not it is a hit when the normal symbol control state flag is a value (02) indicating the normal symbol display time monitoring process and the waiting time after determination has elapsed. When the main CPU 31 is successful, the normal electric accessory release setting process is executed, and a value (03) indicating the normal electric accessory release process is set in the normal symbol control state flag. That is, it sets so that the normal electric accessory release process mentioned later may be performed.

  On the other hand, the main CPU 31 sets a value (04) indicating a normal symbol game end process when it is not a win. That is, it sets so that the normal symbol game completion | finish process mentioned later may be performed.

  In step S254, the main CPU 31 executes the ordinary electric accessory release process. In this process, when the normal symbol control state flag is a value (03) indicating the normal electric accessory release process, the main CPU 31 has a condition that a predetermined number of start prizes are received during the release of the normal electric accessory, It is determined whether or not any of the conditions that the normal electric accessory release time timer is “0” is satisfied.

  When any of the conditions is satisfied, the main CPU 31 updates the variables positioned in the main RAM 33 in order to bring the blade member 84, which is a normal electric accessory, into a closed state. The main CPU 31 sets a value (04) indicating the normal symbol game end process in the normal symbol control state flag. That is, it sets so that the normal symbol game completion | finish process mentioned later may be performed.

  In step S255, the main CPU 31 executes a normal symbol game end process. In this process, when the normal symbol control state flag is a value (04) indicating the normal symbol game end process, the main CPU 31 stores and updates the data indicating the number of reserved symbols related to the normal symbol so as to decrease by “1”. The main CPU 31 updates the normal symbol storage area in order to perform the next normal symbol variation display. The main CPU 31 sets a value (00) indicating the normal symbol storage check process. That is, it sets so that the process which loads the normal symbol control state flag mentioned above may be performed. When this process is finished, this subroutine is finished.

[Illegal sphere check processing]
The illegal sphere check process shown in FIG. 6 will be described with reference to FIG.

  First, in step S310, the main CPU 31 determines whether or not the 2R or 15R big hit flag is set in step S216 or step S219 shown in FIG. If the big hit flag is set, the process proceeds to step S311. If the big hit flag is not set, the process proceeds to step S315.

  If the big win flag is set, the processing executed by the main CPU 31 proceeds to step S311 and whether or not a game ball has won the big winning opening 85 is determined by the count sensor 85S provided in the big winning opening 85. It determines based on the detection signal from. The count sensor 85S is a sensor that counts the number of game balls won in the special winning opening 85, and transmits a detection signal to the main CPU 31 via the I / O each time the number of game balls is counted.

  In step S311, when the main CPU 31 determines that no game ball has been won in the big prize opening 85, the present subroutine is terminated. When the detection signal from the count sensor 85S is transmitted to the main CPU 31 and it is determined that the game ball has won the big winning opening 85, the process proceeds to step S312.

  In step S312, the main CPU 31 executes a process of adding “1” to the total number of game balls won in the big winning opening 85 every time a detection signal is transmitted from the count sensor 85S. That is, in step S312, a process of adding 1 to the value of the grand prize winning total winning counter is set.

  Next, in step S313, the main CPU 31 (determination means) reads out the game ball number information stored in advance in the main ROM 32 in accordance with the big hit gaming state, and compares it with the value of the big winning opening total winning counter. To do. As the number of game balls information, the number of fraud determination balls according to the jackpot game state is stored. When more game balls win the big prize opening 85 during the jackpot game state, It is a value serving as a reference for determining that an illegal act is being performed at the winning opening 85.

  For example, assuming that the maximum number of game balls that can be won in the big winning opening 85 during one round is normally nine, a maximum of 135 game balls can be won in a big hit of 15 rounds. In addition, a maximum of 18 game balls can be won in the big round of 2 rounds.

  However, if the game ball before being counted by the count sensor 85S exists in the big winning opening 85 after the shutter 86 is closed, the gaming ball accidentally wins the big winning opening 85. There is a possibility that the case will occur.

  In such a case, even though no fraud has been performed, a larger number of game balls than the maximum number of game balls have won from the big prize opening 85. Even in such a case, if it is determined that a fraudulent act has been performed, a suspicion is turned to the player who was in the gaming machine that performed the fraudulent act determination.

  In order to prevent such a suspicion from causing unpleasant feelings to a player who has not committed fraud, the present invention assumes a case in which a game ball has accidentally entered the big prize opening 85. Then, a value obtained by giving an allowable number to the maximum number of game balls is stored as game ball number information. For example, a number obtained by adding an allowable number to the maximum number of game balls of 135 in the 15th round and 18 in the 2nd round is set as the game ball number information.

  As the allowable number, an individual number can be set, or a number corresponding to 20% of the maximum number of games that can be won in the special winning opening 85 can be set. For example, if the allowable number is set as a number corresponding to 20% of the maximum number of games, the number of game balls in the 15 round big hit is 135 × 1.2 = 162 pieces, and the game balls in the big round 2 big hit The number information can be set as 18 × 1.2≈22. The numerical values for obtaining the maximum number of games that can be won in the big winning opening 85 and the allowable number are examples, and can be set as appropriate for each special gaming state and each ball game machine. Is.

  In step S313, a comparison between the number of game balls stored in advance in the main ROM 32 in accordance with the big win gaming state and the value of the big winning opening total winning counter is executed. When it is determined that the value is not less than the value of the game ball number information, it is determined that an illegal act is performed, and the process proceeds to the next step S314. On the contrary, when it is determined that the value of the large winning opening total winning counter is smaller than the value of the game ball number information, it is determined that the cheating is not performed, and this subroutine is finished.

  In step S314, the main CPU 31 executes a process of setting the fraud notification output flag for notifying that the fraud is being performed to ON, and proceeds to the next step S319.

  If it is determined in step S310 that the big hit flag is not set, the processing executed by the main CPU 31 proceeds to step S315. The process shown in steps S315 to S318 is a process of determining whether or not a game ball has won the big winning opening 85 by an illegal act during the normal gaming state. Therefore, when it is not necessary to determine that an illegal act has been performed in the normal gaming state, the processes shown in steps S315 to S318 can be omitted.

  In step S315, the main CPU 31 determines whether or not a game ball has won the big winning opening 85 during a normal gaming state that is not in the big hit gaming state. In this case, the detection signal from the count sensor 85S can be determined by the main CPU 31 acquiring it during a normal gaming state that is not in the big hit gaming state.

  When it is determined in step S315 that no game ball has been won in the big winning opening 85, the present subroutine is terminated. Conversely, when it is determined in step S315 that the game ball has won the big winning opening 85, the process proceeds to the next step S316.

  In step S <b> 316, the main CPU 31 adds “1” to the value of the illegal ball counter and sets it in the main RAM 33.

  Assuming that such a situation may occur, in step S317 in the normal gaming state, if a game ball wins the big winning opening 85 and the count sensor 85S detects the game ball, Even when there is a value of the illegal ball counter, which is smaller than the value of “3”, it is handled that fraud has not been performed.

  The value “3” to be compared with the value of the illegal ball count counter is an example, and other appropriate numbers can be used. When it is determined that the value of the illegal ball number counter is “3” or more, the process proceeds to step S318. When it is determined that the value of the illegal ball number counter is less than “3”, this subroutine is terminated.

  In the next step S318, the main CPU 31 executes a process of turning on a fraud notification output flag for notifying that a fraudulent act is being performed, and proceeds to the next step S319.

  If the fraud notification output flag is already set to ON in the processing in step S314 and step S318, the processing proceeds to the next step S319 without executing the processing in step S314 and step S318.

  In step S319, the main CPU 31 executes fraud notification output processing and ends this subroutine. The fraud notification output process will be described later with reference to FIG.

  As described above, in the present invention, there are two independent counters, namely, the illegal number counter that counts the number of balls entered during the normal gaming state and the big prize opening total prize counter that counts the number of balls entered during the big hit gaming state. Used to count. Therefore, when the big hit game state is started in the middle of the normal game state, the value of the illegal ball counter is temporarily not added until the big hit game state is ended. Then, when the big hit gaming state ends and the normal gaming state is restored, the illegal ball counter is continuously counted.

  Apart from this embodiment, when the big hit gaming state is started in the middle of the normal game, the illegal ball that has been added up to now in the process in step S216 or step S219 shown in FIG. A configuration may be used in which the value of the number counter is reset to a value of “0” and the value of the illegal ball number counter is added again from “0” after the big hit gaming state is completed.

[Unauthorized notification output processing]
In step S330 in FIG. 12, the main CPU 31 determines whether or not the fraud notification output flag is ON. That is, it is determined whether or not the fraud notification output flag is turned ON in step S314 or step S318 shown in FIG. When it is determined that the fraud notification output flag is ON, the process proceeds to step S331, and when it is determined that the fraud notification output flag is not ON, this subroutine is terminated.

  In step S331, the main CPU 31 executes processing for setting a fraud notification command. The fraud notification command is transmitted to the sub control circuit 56 by the command output process of step S124 shown in FIG. The sub-control circuit 56 that has received the fraud notification command includes a display device (notification unit) such as the liquid crystal display device 5 and the lamp 24 or a decoration device (notification unit), and an acoustic device (notification unit) such as the speaker 21. Appropriate use is made to notify that fraud has been carried out. If the fraud notification command is already set in the process in step S331, the process proceeds to the next step S332 without executing the process in step S331.

  In addition, by connecting a communication device (notification means) or the like that communicates with the ball and ball game machine 1 and a management room of the game hall or an employee in the game hall by wire or wirelessly to the sub-control circuit 56, the communication device It is also possible to notify that fraud is being performed using.

  Next, in step S332, the main CPU 31 executes processing for setting an unauthorized notification time timer. By setting the unauthorized notification time timer, the unauthorized notification can be canceled when the set unauthorized notification time has elapsed. The fraud notification time can be set to an appropriate time as necessary. If the fraud notification time timer has already been set in the process in step S332, the process proceeds to the next step S333 without executing the process in step S332.

  In the next step S333, the main CPU 31 executes fraud notification release processing according to the value of the fraud notification time timer, and ends this subroutine. The unauthorized notification release process will be described with reference to FIG.

[Unauthorized Notification Release Processing]
In step S340 of FIG. 13, the main CPU 31 determines whether or not the fraud notification time timer set in step S332 of FIG. 12 is “0”. When it is determined that the unauthorized notification time timer is not “0”, this subroutine is terminated without setting the unauthorized notification release command. When it is determined that the unauthorized notification time timer is “0”, the process proceeds to step S341.

  In step S341, the main CPU 31 executes processing for setting a fraud notification cancel command, and proceeds to the next step S342. In step S342, the main CPU 31 executes a process of clearing the storage area used for fraud determination (such as the value of the total prize winning total winning counter) and ends the present subroutine. In this step S342, the illegal ball counter may be reset.

[Sub control circuit main processing]
Next, the sub control circuit main process executed by the sub control circuit 56 will be described with reference to FIG. The sub-control circuit main process is a process that starts when the power is turned on.

  In step S410 of FIG. 14, the sub CPU 61 executes initial setting processing such as RAM access permission and work area initialization. In the next step S411, the sub CPU 61 executes a random number update process for updating the random number values of various random number counters positioned in a predetermined area of the work RAM 63.

  Then, in the next step S412, the sub CPU 61 analyzes the received command and executes a command analysis process corresponding to the analyzed command. Here, an analysis process and an unauthorized notification process of the unauthorized notification command set by the main CPU 31 in step S331 and the unauthorized notification cancel command set in step S341 shown in FIG. 12 are executed.

  The details of the command analysis processing for the fraud notification command and the fraud notification cancel command transmitted from the main CPU 31 will be described later with reference to FIG. In the next step S413, the sub CPU 61 executes display control processing for performing image display control in the liquid crystal display device 5. Then, in the next step S414, the sub CPU 61 executes a sound control process for controlling the sound generated from the speaker 21. In the next step S415, the sub CPU 61 executes lamp control processing for controlling the light emission of the various lamps 24. When this process ends, the process returns to the random number update process again and is repeated.

  In this way, in the sub control circuit main process in the sub control circuit 56, after the initial setting process is completed, the lamp control process is repeatedly executed from the random number update process.

  The sub-control circuit main process shown in FIG. 14 is a process of the sub-control circuit 56 when the illegal sphere check process (see FIG. 11) is executed by the main CPU 31 of the main control circuit 55. In contrast to this embodiment, in order to reduce the processing load on the main CPU 31, it is also possible to execute the illegal ball check process (see FIG. 11) on the sub-control circuit 56 side without performing it on the main control circuit 55 side. . FIG. 15 shows the main process of the sub control circuit 56 when the illegal ball check process shown in FIG. 11 is changed to be executed on the sub control circuit 56 side.

  When the illegal ball check process shown in FIG. 11 is executed on the sub control circuit 56 side, the main control circuit 55 side communicates the information on the 2R or 15R big hit flag, the signal of the count sensor 85S, etc. It is necessary to obtain it via I / O or the like. In the embodiment described below, a case will be described in which information on the 2R and 15R jackpot flags, the state of the count sensor 85S, and the like are acquired from the main control circuit 55 side through communication.

  In the sub-control circuit main process shown in FIG. 15, the same process number as the process described in the sub-control circuit main process shown in FIG. Description of is omitted. In the sub-control circuit main process shown in FIG. 15, the illegal ball check process of step S420 is executed subsequent to step S412. After step S420 is executed, the processing from step S413 is executed as in the sub control circuit main processing shown in FIG.

  In step S420, the sub CPU 61 integrates the detection signals of the count sensor 85S transmitted from the main control circuit 55, and obtains the value of the big winning opening total winning counter or the illegal ball counter, and the above-mentioned illegal ball. The illegal ball check process is executed by comparing with the game ball number information used for the determination. As the illegal sphere check process performed in step S420, the same process as the illegal sphere check process in the main CPU 31 shown in FIG. 11 is executed.

  The number of game balls used in the illegal ball check process can be stored in the program ROM 62. In addition, the work RAM 63 of the sub control circuit 56 can store information on the jackpot flag acquired from the main control circuit 55, the value of the total winning prize total winning counter, the value of the illegal ball counter, etc. .

[Command analysis processing]
The command analysis process shown in step S412 of FIGS. 14 and 15 will be described with reference to FIG.

  First, in step S430 of FIG. 16, the sub CPU 61 determines whether or not there is a received command depending on whether or not the command is stored in the command buffer. In this process, if it is determined that there is a received command, the sub CPU 61 proceeds to step S431, and reads command data from a command buffer positioned in a predetermined area of the work RAM 63. Subsequent processing will be described in detail below. On the other hand, when determining that there is no received command, the sub CPU 61 ends the present subroutine.

  When the received command is read in step S431, the process proceeds to step S432, and the sub CPU 61 determines whether or not the variation pattern designation command is received based on the read command data. In step S432, if the sub CPU 61 determines that it has received the variation pattern designation command, the sub CPU 61 proceeds to step S440, and produces an effect for determining various effect patterns such as a decoration pattern variation pattern and an image effect pattern for displaying a background image. The pattern determination process is executed. When this process is finished, this subroutine is finished.

  On the other hand, if it is determined in step S432 that the sub CPU 61 has not received the variation pattern designation command, the sub CPU 61 proceeds to step S433, and determines whether or not the derived symbol designation command has been received based on the read command data. To do.

  If the sub CPU 61 determines in step S433 that the derived symbol designation command has been received, the sub CPU 61 proceeds to step S439, and executes a derived ornament symbol determination process for determining a decorative symbol to be derived and displayed based on the derived symbol designation command. This subroutine is finished. On the other hand, if it is determined in step S433 that the derived symbol designation command has not been received, the sub CPU 61 proceeds to step S434, and determines whether or not a fraud notification command has been received.

  If the sub CPU 61 determines in step S434 that a fraud notification command has been received, the sub CPU 61 proceeds to step S435, executes fraud notification processing, and ends this subroutine. As the fraud notification process, for example, a fraud notification is executed by operating a display device such as the liquid crystal display device 5 or the lamp 24 or an audio device such as a decoration device or the speaker 21.

  On the other hand, if the sub CPU 61 determines in step S434 that the fraud notification command has not been received, the sub CPU 61 proceeds to step S436 and determines whether or not a fraud notification release command has been received.

  If the sub CPU 61 determines in step S436 that a fraud notification cancel command has been received, the sub CPU 61 proceeds to step S437, executes fraud notification cancel processing, and ends the present subroutine. As the fraud notification canceling process, for example, a process of canceling the operation of the display device such as the liquid crystal display device 5 and the lamp 24 or the sound device such as the decoration device 21 that is executing the fraud notification is executed.

  On the other hand, if the sub CPU 61 determines in step S436 that it has not received the fraud notification cancel command, the sub CPU 61 proceeds to step S438, executes processing corresponding to the received command, and ends this subroutine.

  Next, the opening / closing timing of the special winning opening during the special gaming state, the counting timing of the total winning winning counter, the timing of the illegal counting counter, the reset timing of the total winning winning counter and the illegal counting counter Will be described with reference to FIG.

  FIG. 17 shows a process for monitoring a ball remaining in the big prize opening after the special electric game is released and the special prize opening 85 is closed during the big hit gaming state (during the period of checking the game remaining in the big prize opening) ) Shows a timing chart of the ball game machine 1 configured not to perform counting by the large winning opening total winning counter (counting means).

  The timing chart shown in FIG. 17 shows the transition of the control state flags (03) to (07) in the 2R big hit gaming state (see FIG. 8), the opening / closing timing of the big winning opening 85, and the count of the big winning opening total winning counter. The timing and the non-counting timing, the timing for resetting the big prize total winning counter, the counting timing and the non-counting timing for the illegal ball counter, and the timing for resetting the illegal ball counter are shown. Note that FIG. 17 shows the timing of each operation in the 2R big hit gaming state, but even in the 15R big hit gaming state, the same operation is performed with only a different number of rounds. Note that all of the timing charts in FIG. 17 can be used for the control of the ball game machine 1, or only one or a plurality of timings can be used for the control of the ball game machine 1.

  With reference to FIG. 17, the counting process of the big winning opening total winning counter will be schematically described in time series.

  First, when the 2R (or 15R) jackpot gaming status flag is set to ON, the control status flag is set to (03), and the jackpot start interval management process is executed. Here, you may make it reset a large winning opening total winning counter. It should be noted that the illegal ball number counter may be reset at this timing, or the illegal ball number counter can be reset when the special gaming state ends. Further, in step S342 shown in FIG. 13, when the storage area used for the fraud determination is cleared, the illegal ball counter may be reset. In the big hit gaming state, since the big hit flag of 2R (or 15R) is set, the processing does not proceed to step S315 to step S318 shown in FIG. Therefore, during the big hit gaming state, the process of step S316 shown in FIG. 11 is not executed, and the counting of the illegal ball number counter is interrupted.

  As shown in FIG. 17, when the big hit gaming state is started, a reset signal for the illegal ball counter is output, and the value of the illegal ball counter is reset to “0” based on the reset signal. It is also possible to newly start counting the number of illegal balls in the normal gaming state after the big hit gaming state ends. By doing so, in the normal gaming state that continues for a long time, it is possible to reduce the problem of incorrect notification of incorrect notification by accumulating the number of illegal balls counted by chance.

  When the time corresponding to the big hit start interval management process elapses, the control state flag is set to (04). Then, until the time set in the big prize opening time timer elapses or until a predetermined number of game balls enter the big prize opening 85, the special electric accessory is driven to the big prize opening 85. Is released.

  When the winning prize winning counter reaches a predetermined number or more, or when the upper limit time for opening the winning prize opening 85 has elapsed, the special electric accessory is activated to close the winning prize opening 85. Is stopped, and the control state flag is set to (05), and the winning ball remaining ball monitoring process is performed. While (05) is set in this control state flag, the process proceeds directly to the next step S313 without performing the process of adding to the big winning opening total winning counter in step S312 shown in FIG. Configure.

  By configuring in this way, the period until the game ball remaining in the big prize opening 85 is discharged when the big prize opening 85 is closed and the winning of the game ball is shifted to a difficult state. During the middle period (that is, during the period in which the special winning opening residual ball monitoring process is being performed), it is possible not to count the game balls used for the illegal winning determination. As a result, it becomes possible to exclude the game balls remaining in the big prize opening 85 when the special electric winninges are stopped and the big prize opening 85 is closed from the determination of the illegal prize, and more accurately. It is possible to make an illegal winning determination. Therefore, it is possible to reduce false reports that the occurrence of a fraudulent activity is notified even though the illegal act is not actually performed.

  In the special winning mouth residual ball monitoring process, if the predetermined special winning mouth residual ball monitoring time has elapsed and the special prize opening number counter has not reached the maximum number of outstanding winning mouth openings, the next time The control state flag is set to (06) toward the opening of the special winning opening 85. Thereafter, a waiting time management process before reopening the big winning opening corresponding to the interval between rounds is executed.

  In the waiting time management process before the big winning opening reopening, when the time corresponding to the interval between rounds elapses, the control state flag is set to (04) again. Then, during the time set in the big prize opening time timer or until a predetermined number of game balls enter the big prize opening 85, the special electric accessory is driven to open the big prize opening 85. . Then, when the value of the special prize winning counter reaches a predetermined number or more, or when the upper limit time for opening the special prize winning port 85 has elapsed, a special electric accessory is used to close the special prize winning port 85. Is stopped, the control state flag is set to (05), the winning ball remaining ball monitoring time is set to the waiting time timer, and the winning ball remaining ball monitoring process is performed. As long as (05) is set in this control state flag, as in the previous case, the process of adding to the big prize winning total winning counter is not performed.

  When the winning ball residual ball monitoring time has elapsed in the big winning mouth residual ball monitoring process, and the big winning mouth opening number counter is equal to or greater than the maximum winning opening number of times (in the case of the final round). The value (07) indicating the big hit end interval process is set in the control state flag, and the time corresponding to the big hit end interval process is set in the waiting time timer. Then, after the time corresponding to the jackpot end interval processing has elapsed, the jackpot gaming state is terminated and the normal gaming state is restored. When returning to the normal gaming state, the counting process of the illegal ball counter is started again.

  Next, another embodiment of the present invention will be described with reference to FIG.

  FIG. 18 shows an example in which two large winning holes 85 a and 85 b are formed in the gaming area 4 as a representative of the case where a plurality of large winning holes are formed in the gaming area 4. It is possible to appropriately set how to open the two big winning openings. For example, in a ball game machine with 2 round jackpots and 15 round jackpots, one big prize opening is opened in the case of two round big hits, and the other big prize opening is opened in the case of 15 rounds big hit. It is also possible, and it is also possible to open two big prize openings during the big hit. In this way, when the two big winning openings 85a and 85b are configured in the game area 4, the two big winning openings 85a and 85b are handled as separate big winning openings, respectively, The fraud determination described above can be performed on 85a and 85b. Alternatively, the fraud determination can be performed by using the total number of game balls won in the two big winning openings 85a and 85b as the number of comparison targets to be performed in the illegal ball check process.

  When the two big winning openings 85a and 85b are distinguished from each other, since the fraud determination is individually made for each of the big winning openings 85a and 85b, it is necessary to make the fraud determination of the gaming machine more reliable. Can do. On the other hand, when performing fraud determination on the total number of game balls won in the two big winning openings 85a and 85b, the processing load of fraud determination can be reduced.

  Next, still another embodiment of the present invention will be described with reference to FIG.

  The embodiment shown in FIG. 19 is a case where the illegal ball check process of the present invention is applied to a modified example of the start port 83 provided in the game area 4. In particular, in the case where the starting port 83 is configured as a starting port 88 with a blade member 84 and the winning port 88a is provided at the upper portion of the starting port 88, the illegal ball check processing of the present invention is performed. It is an example of a structure when applying.

  Note that the winning opening 88a may be configured as a starting port, and the embodiment illustrated in FIG. 19 includes the case where it is configured in this way.

  The blade member 84 provided at the start port 88 is opened for a certain period of time, for example, when an electric solenoid (not shown) is activated when a game ball passes the ball passage detector 81 (see FIG. 3). After that, the opening / closing is controlled so as to return to the closed state. That is, the blade member 84 can take both an open state in which game balls can easily enter and a closed state in which game balls cannot easily enter.

  The start port 88 may be provided with a sensor similar to the count sensor 85S provided in the large winning port 85 described in the first embodiment, as detection means for detecting a game ball won in the start port 88.

  When winning the winning opening 88a or the starting opening 88 arranged above the start opening 88, a lottery determination lottery is performed, and, for example, the display of variation of the effect symbol is started in the display area of the liquid crystal display device 5. .

  In this embodiment, when it is detected that the maximum number of winning balls has been entered when the blade member 84 provided at the start port 88 is in an open state, one or more game balls are accidentally placed inside the blade member 84. It may exist, and after that, it is possible to enter the starting port 88 sequentially.

  Thus, even when there is a ball exceeding the maximum number of winning balls at the start port 88, the game ball that has entered the start port 88 is entered based on the fact that the blade member 84 is illegally opened. It is possible to determine whether an illegal act has occurred by determining whether the ball is a ball or a game ball that has entered due to a problem in the arrangement of the blade member 84 and the winning opening 88a. Moreover, when it is determined that an illegal act has occurred, it can be notified that the illegal act has been performed.

  Also in the case of the third embodiment, as in the case of the first embodiment, the number of game balls that have entered the start opening 88 and the fraud determination stored in advance in the main ROM 32 or the like (information section). By comparing with the number of balls, it is possible to determine whether the ball has entered the start port 88 due to fraud or whether it has accidentally entered the start port 88. As a determination method, a control flow such as the illegal sphere check process of FIG. 11 described in the first embodiment can be used.

  As the opening / closing control of the blade member 84, the opening / closing control of the blade member 84 is different depending on whether it is in the normal gaming state, or in the gaming state in the probability changing state or the short time state. For example, the blade member 84 is controlled so that the number of times of opening and closing the blade member 84 increases during certain changes or time reductions.

  The opening time during which the blade member 84 is in the open state is a short opening time in the normal gaming state, and is a long opening time in the gaming state in the probability changing state or the short time state. In addition, when looking at the interval time from when the blade member 84 is in the closed state to when it is again in the open state, it is a long interval time in the normal gaming state, whereas in the probability variation state or the short time state During the game state, the interval time is short.

  For this reason, the number of game balls that enter the start port 88 is a small number during the normal game state, and in the game state in the probabilistic state or in the short-time state, the number of balls that are entered is larger than that in the normal state. It becomes the number. Therefore, as the number of fraud determination balls as a criterion for the start port 88, a predetermined number can be set in the normal gaming state, and in the gaming state in the probability variation state or the short time state. It can be set as more than the number used in the normal gaming state.

  In this way, by setting the number of fraud determination balls serving as a determination criterion for the start port 88, the start port is configured such that the winning port 88a is provided above the start port 88 with the blade member 84. In contrast, it is possible to suitably determine whether or not an illegal act is being performed.

  In the embodiment described above, an example in which the main control circuit 55 and the sub control circuit 56 are each provided with a plurality of control circuits has been described. However, the present invention is not limited to these configurations. Alternatively, for example, the main control circuit 55 and the sub control circuit 56 may be configured as a single board.

  Further, in the above-described embodiments, description has been made by taking a bullet ball game machine with a liquid crystal display device as an example. However, the present invention is not limited to these configurations, and is referred to as a wing mono and a hiko mono. The pachinko gaming machine to be played, the pachinko gaming machine called the right thing, and other forms can also be used.

  The present invention can be suitably applied to prevention of fraud against gaming machines and the like.
