[Main flow of main controller]
Next, a general flow of processing performed by main controller 1000 will be described using a main flowchart shown in FIG. After powering on the gaming machine, the process of FIG. 11A is executed. That is, after turning on the power of the gaming machine and making initial settings (not shown), in step S4002, main controller 1000 confirms the input port of the RAM clear button, and reset button (RAM clear) of power supply unit 3500. Button) has been operated, that is, whether or not an operation of clearing the contents of the RAM has been performed intentionally by a game hall manager or the like. In the case of Yes in step S4002, in step S4004, main controller 1000 clears all the RAM contents (for example, information in gaming state temporary storage means 1190) on the main controller 1000 side. Next, in step S4006, the information transmission control means 1300 transmits ram clear information (command) indicating that the RAM of the main controller 1000 has been cleared to the sub main control board 211 side (even if it is transmitted at this timing). Alternatively, a command may be set at this timing and transmitted by a control command transmission process described later), and the process proceeds to step S4018. On the other hand, in the case of No in step S4002, in step S4008, main controller 1000 checks the contents of the RAM area in main controller 1000 (for example, the checksum recorded during power interruption and the RAM area are stored in the RAM area). Comparison with the amount of information).

  Next, in step S4010, main controller 1000 determines whether or not the contents of the RAM are not normal based on the check result (whether or not the information at the time of power interruption is accurately backed up in RAM). If YES in step S4010, that is, if the data backed up in the RAM is abnormal, the process proceeds to step S4004 (RAM clear process described above). On the other hand, if NO in step S4010, that is, if the data backed up in the RAM is normal, main controller 1000 transmits various information commands to sub-main control board 211 in step S4012 (transmits at this timing). Alternatively, a command may be set at this timing and transmitted by a control command transmission process described later). Next, in step S4013, main controller 1000 refers to the flag area of specific game related information temporary storage means 1195, and determines whether or not the probability change transition reservation flag is on. In the case of Yes in step S4013, in step S4014, main controller 1000 transmits a high profit redisplay command to sub-main control board 211 (may be transmitted at this timing, or set a command at this timing. In addition, it may be configured to transmit by a control command transmission process described later), and the process proceeds to step S4015. On the other hand, also in the case of No in step S4013, the process proceeds to step S4015.

  Next, in step S4015, the main controller 1000 resets the main winning prize counter 1174d and the sub winning prize counter 1174e, and proceeds to step S4018. Next, in step S4018, the main controller 1000 executes a scheduled execution interrupt (for example, a hardware interrupt about every 1.5 ms) related to the main process on the main controller 1000 side shown in step S1000 of FIG. In this example, the interrupt cycle is set to T). As a result, when the execution scheduled interrupt timing is reached, step S1000 in the figure is executed, and the process of step S4020 Migrate to After the transition to step S4020, main controller 1000 repeatedly executes various random number update processing (for example, random number counter increment processing) until the next scheduled interrupt timing is reached.

Next, timer interrupt processing will be described. Main controller 1000 executes the process of FIG. 11B based on an interrupt request generated when the scheduled interrupt timing is reached. That is, triggered by the arrival of the scheduled interrupt period T (for example, a hardware interrupt about every 1.5 ms), in step S1100, the main controller 1000 executes an auxiliary game content determination random number acquisition process described later. Next, in step S1200, main controller 1000 executes an electric accessory drive determination process described later. Next, in step S1300, main controller 1000 executes a main game content determination random number acquisition process, which will be described later. Next, in step S1400, main controller 1000 executes a main game symbol display process described later. Next, in step S2000, main controller 1000 executes special game operating condition determination processing described later. Next, in step S2100, main controller 1000 executes a special game control process described later. Next, in step S3000, the main controller 1000 (especially the prize ball payout determining means 1400) pays out the prize ball payout control process (drive control of the prize ball payout unit 33, etc.) based on the winning opening where the game ball has won. The device 3000 is executed and processing for managing the result is executed. Next, in step S3100, main controller 1000 executes external signal output processing (information output to external terminal board, hall computer H, etc.) (game-related information, discharge ball abnormality information, fraud detection command, etc.). Send). Next, in step S3200, main controller 1000 transmits a control command transmission process (the command set in each of the above processes is transmitted to the sub main control unit side, and the sub main control board 211 side performs an effect according to the command. To return to the process that was being executed immediately before the execution of this interrupt process.

  Next, NMI interrupt processing will be described. As described above, main controller 1000 is configured such that the power interruption signal from the reset IC is input to the NMI terminal of the CPU, and the process of FIG. Is done. That is, when the gaming machine is powered off (NMI interrupt in this example), in step S4604, main controller 1000 sets power interruption information (for example, checksum) based on the information in the RAM area. In step S4606, main controller 1000 prohibits writing to the RAM area, prohibits timer interrupt processing, and shifts to power-off waiting loop processing.

[Sub-flow of main controller]
Next, the special game control process according to the subroutine of step S2100 in FIG. 11 will be described using the flowchart shown in FIG. First, in step S2102, the special game execution control unit 1173 refers to the flag area of the special game related information temporary storage unit 1194, and determines whether or not the condition device operation flag is on. In the case of Yes in step S2102, in step S2150, the special game execution control unit 1173 executes special game start control processing. Next, in step S2200, the special game execution control means 1173 executes a special winning opening control process described later. Next, in step S2500, the special game execution control means 1173 executes special game end control processing, and returns to the calling source of this subroutine. On the other hand, in the case of No in step S2102, the special game execution control unit 1173 determines that it is not time to execute the special game, and returns to the caller of this subroutine.

  Next, with reference to the flowchart shown in FIG. 13, the special winning opening control process according to the subroutine of step S2200 in FIG. 12 will be described. First, in step S2202, the special winning opening control unit 1174 refers to the flag area of the special game related information temporary storage unit 1194, and determines whether or not the winning control continuation flag is on. If Yes in step S2202, the process proceeds to step S2250. On the other hand, in the case of No in step S2202, in step S2204, the special winning opening control unit 1174 turns on the winning control continuing flag in the flag area of the special game related information temporary storage unit 1194. Next, in step S2206, the big winning opening control means 1174 refers to the opening mode determination table 1172b (see also FIG. 14) based on the big hit symbol and the round number counter value, and sets the opening mode of the big winning port 141a. .

  Next, in step S2208, the big winning opening control means 1174 resets (clears to zero) the counter values of the main side winning number counter 1174d and the sub side winning number counter 1174e. Next, in step S2210, the special winning opening control means 1174 starts the round timer 1174a, and proceeds to step S2250. Steps S2202 to S2210 are the initial processing stage, and initial processing at the time of round execution related to opening / closing of the special winning opening 141a in the special game is performed in this processing.

  Next, in step S2250, the special winning opening control means 1174 performs a special winning opening / closing control process, and proceeds to step S2300. Next, in step S2300, the special winning opening control means 1174 executes a preparation time control process. Next, in step 2350, the special winning opening control means 1174 executes a winning control process. Next, in step 2400, the special winning opening control means 1174 executes round control end processing and returns to the caller of this subroutine.

Here, FIG. 14 is an example of an opening mode determination table 1172b that is referred to when determining the opening mode of the special winning opening 141a. In the special game in this embodiment, a combination of long opening (long opening A and long opening B) and short opening (or only one) over a plurality of rounds.
The special winning opening 141a is opened in the opening mode. For example, in the special game related to the first winning symbol (16 round big hit symbol) Z1, the first round is long open A, the second to twelfth rounds are long open B, and the thirteenth to sixteenth rounds. Is short open. In the special game relating to the second winning symbol (16 round big hit symbol) Z2, the first round is long open A, the second to fourth rounds are long open B, and the fifth to sixteenth rounds are short. Open. In the special game relating to the third winning symbol (four round big hit symbol) Z3, the first round is long open A and the second to fourth rounds are long open B. In the special game related to the fourth winning symbol (16 round big hit symbol) Z4, the first round is the long opening A, and the second to sixteenth rounds are the long opening B. In the special game related to the fifth winning symbol (small winning symbol) Z5, the first round is short open.

  The long opening A is an opening pattern of “28000 ms opening + 1956 ms closing + 52 ms opening”. The long opening B is an opening pattern of “28000 ms opening”. The short opening is an opening pattern of “52 ms opening”. When the first round is long open, the long open A open pattern is selected, and when the second round and thereafter are long open, the long open B open pattern is selected. By using the opening pattern of the long opening A, it is possible to share the control software with a gaming machine adopting an opening pattern in which the big winning opening is opened twice in one round. Moreover, in this embodiment, there are only three types of opening modes that can be selected by the special winning opening 141a: long opening A, long opening B, and short opening, but the present invention is not limited to this. There is no problem even if a proper opening time or opening pattern is selected.

[Action]
Next, the effect | action in this embodiment is demonstrated, referring FIGS. 15-17.

[Long open A]
As a first example, a description will be given focusing on “a certain round” in “a certain special game” including a unit game of long open A. Specifically, the first round of the special game related to the first winning symbol Z1 will be described as an example. In the first round of the special game related to the first winning symbol Z1, the special winning opening 141a operates in the order of “28000 ms opening / 1956 ms closing / 52 ms opening / closing”.

  FIG. 15 is a timing chart showing the operation content when the opening mode of the special winning opening 141a is the long opening A. First, at the timing of N1 in FIG. 15 (start timing of the first round of the special game), an opening drive signal that activates the opening / closing solenoid is output from the large winning opening control means 1174 to the large winning device 140 opening / closing solenoid. The Also, at the timing of N1, an open holding signal for holding the operating state of the open / close solenoid is output from the special winning opening control means 1174 to the open / close solenoid. As a result, the open / close solenoid is activated, the special prize opening 141a is opened, the special prize winning device 140 starts operating, and the first round of the special game is started. Note that the hit demonstration display time is between the timing of N0 and the timing of N1 in FIG. For example, in the case of a special game related to the first winning symbol Z1, the winning demonstration display time is set to 10,000 ms.

  The open hold signal is set to a voltage (power) lower than the open drive signal. In this way, by using the open hold signal having a voltage lower than the open drive signal, it is possible to prevent overheating of the open / close solenoid of the big winning device 140 in the operating state. In addition, since the output of the opening holding signal is turned on at the same timing as the opening driving signal, on / off control of the opening driving signal and the opening holding signal can be facilitated.

Next, at the timing of N2 in FIG. 15, the output of the opening drive signal is turned off when 100 ms has elapsed since the opening of the special winning opening 141a. At this time, since the output of the open holding signal is on, the open / close solenoid of the special winning device 140 remains in the activated state, and the open state of the special winning opening 141a is maintained.

  Next, at the timing of N3 in FIG. 15, the output of the opening holding signal is turned off when 28000 ms has elapsed since the opening of the special winning opening 141a. As a result, the open / close solenoid of the special winning device 140 is deactivated, and the special winning opening 141a is closed (only for 1956 ms).

  Next, at the timing of N4 in FIG. 15, the output of the opening drive signal is turned on when 1956 ms has elapsed since the closing of the special winning opening 141a. At the timing N4, the output of the open holding signal is turned on. As a result, the special winning opening 141a is opened again.

  Next, at the timing of N5 in FIG. 15, the output of the opening drive signal is turned off when 52 ms has elapsed since the opening of the special winning opening 141a. Further, at the timing of N5, the output of the open holding signal is turned off. As a result, the open / close solenoid of the special winning device 140 is deactivated, the special winning opening 141a is closed, and the special winning device 140 stops operating. If the sum of the counter value of the main winning prize counter 1174d and the counter value of the sub winning prize counter 1174e reaches a predetermined maximum winning number before the timing of N3 in FIG. Is turned off, the special winning opening 141a is closed, and the special winning apparatus 140 stops operating.

  In addition, a closing time between rounds of the special winning opening 141a is provided between the time when the special winning device 140 stops operating in the first round of the special game and the next second round is started. In the present embodiment, the closing time between rounds of the special winning opening 141a is set to 600 ms, which is the same as the designed time interval at which the launching mechanism 21 can continuously launch game balls.

[In case of long open B]
As a second example, a description will be given focusing on “a certain round” in “a certain special game” including a unit game of long open B. Specifically, the second round of the special game related to the first winning symbol Z1 will be described as an example. In the second round of the special game related to the first winning symbol Z1, the special winning opening 141a operates in the order of “28000 ms open / close”.

  FIG. 16 is a timing chart showing the operation content when the opening mode of the special winning opening 141a is the long opening B. First, at the timing of N11 in FIG. 16 (start timing of the second round of special game), the output of the release drive signal is turned on. Further, at the timing of N11, the output of the open holding signal is turned on. As a result, the open / close solenoid of the special winning device 140 is activated, the special winning opening 141a is opened, the special winning device 140 starts operating, and the second round of the special game is started.

  Next, at the timing of N12 in FIG. 16, the output of the opening drive signal is turned off when 100 ms has elapsed since the opening of the special winning opening 141a. At this time, the output of the opening holding signal remains on, and the state where the special winning opening 141a is opened is held.

Next, at the timing of N13 in FIG. 16, the output of the opening holding signal is turned off when 28000 ms has elapsed since the opening of the special winning opening 141a. As a result, the open / close solenoid of the special winning device 140 is deactivated, the special winning opening 141a is closed, and the special winning device 140 stops operating. Before the timing of N13 in FIG. 16 elapses, the counter value of the main side winning number counter 1174d and the sub side winning number counter 11
When the sum with the counter value of 74e reaches a predetermined maximum number of winnings, the output of the open holding signal is turned off, the large winning opening 141a is closed, and the large winning device 140 stops operating.

  In addition, during the second round of the special game, a closing time between rounds of the big prize opening 141a is provided between the time when the big prize winning device 140 stops operating and the time when the next third round is started. The closing time between rounds of the grand prize winning opening 141a is set to 600 ms, which is the same as in the case of the long opening A.

[In case of short opening]
As a third example, a description will be given focusing on “a certain round” in “a certain special game” including a short-open unit game. Specifically, the 13th round of the special game related to the first winning symbol Z1 will be described as an example. In the 13th round of the special game related to the first winning symbol Z1, the special winning opening 141a operates in the order of “52 ms open / close”.

  FIG. 17 is a timing chart showing the operation contents when the opening of the special winning opening 141a is short opening. First, at the timing of N21 in FIG. 17 (the start timing of the 13th round of the special game), the output of the release drive signal is turned on. Further, at the timing of N21, the output of the open holding signal is turned on. As a result, the open / close solenoid of the grand prize winning device 140 is activated, the grand prize winning opening 141a is opened, the grand prize winning device 140 starts operating, and the 13th round of the special game is started.

  Next, at the timing of N22 in FIG. 17, the output of the opening drive signal is turned off when 100 ms has elapsed since the opening of the special winning opening 141a. At the timing N22, the output of the open holding signal is turned off. As a result, the open / close solenoid of the special winning device 140 is deactivated, the special winning opening 141a is closed, and the special winning device 140 stops operating.

  In addition, a closing time between rounds of the special winning opening 141a is provided between the time when the special winning device 140 stops operating in the thirteenth round of the special game and the next fourteenth round is started. The closing time between rounds of the grand prize winning opening 141a is set to 600 ms, which is the same as in the case of the long opening A.

  As illustrated in the case of the long opening A, the long opening B, and the short opening, the closing time between rounds of the special winning opening 141a is a designed time interval in which a game ball can be continuously launched by the launch mechanism 21. The same 600 ms is set. Thereby, before the game ball that has reached the winning opening opening / closing member 231 for the first time (slid to the closed position) after the closing of the winning opening 141a flows down the upper surface of the winning opening opening / closing member 231, After the closing time between rounds has elapsed, the special winning opening 141a is opened again. For this reason, it is possible to reduce the number of game balls (so-called waste balls) that are discharged as out balls without being able to enter the big winning opening 141a closed between a plurality of rounds. Moreover, since the closing time between rounds of the special winning opening 141a is shorter than before, the time required for digesting the special game can be reduced.

Further, in the present embodiment, it is determined that each round is ended when the detection of the game ball by the main side detection sensor 143s and the sub side detection sensor 146s becomes invalid. The detection valid time during which the detection of the game ball by the main-side detection sensor 143s and the sub-side detection sensor 146s is valid during the closing time between rounds of the grand prize winning opening 141a is set to 592 ms out of 600 ms, and the main-side detection sensor 143s and The detection invalid time when the detection of the game ball by the sub-side detection sensor 146s is invalid is set to 8 ms after the detection valid time (592 ms) has elapsed. In this way, the detection invalid time of the main side detection sensor 143s and the sub side detection sensor 146s is 8 ms (2 interrupts) shorter than the detection valid time.
In this way, the minimum winning time 141a is closed almost at the same time as the closing time of the grand prize opening 141a is shortened while ensuring the minimum time in which the end of the round can be determined is secured. The game ball that has passed through can be reliably detected.

  In the above-described embodiment, the closing time between rounds of the grand prize winning opening 141a is set to the same time as the design time interval at which the launching mechanism 21 can continuously launch game balls. It may be set to a time shorter than the designed time interval at which the game ball can be continuously launched by the launch mechanism 21, and the same effect as in the above-described embodiment can be obtained. it can.

  In the above-described embodiment, the detection effective time during which the detection of the game ball by the main side detection sensor 143s and the sub side detection sensor 146s is valid, and the main side detection sensor 143s, Although the detection invalid time when the detection of the game ball by the sub-side detection sensor 146s is invalid is set, it is not limited to this. For example, the above-described detection valid time and detection invalid time are set for the main-side detection sensor 143s, and the sub-side detection sensor 146s is set so that the detection of the game ball is invalid during the entire round closing time. Thus, the control may be different between the main side detection sensor 143s and the sub side detection sensor 146s. Thereby, it is possible to prevent an illegal act of illegally detecting and operating the sub-side detection sensor 146s during the closing time between rounds.

  Further, for example, the main side detection sensor 143s and the sub side detection sensor 146s may be set so that the detection of the game ball is effective during the entire closing time between rounds. In this case, the end of each round is determined based on the on / off state of the opening drive signal for the open / close solenoid of the winning device 140 and the on / off state of the opening holding signal.
