  The random number of the special symbol data 1 starts from “0” when the power is turned on, and is incremented by “1” every time the normal symbol / special symbol main random number update processing described later is performed. And the addition is repeated again. The random number of the special symbol data 2 starts from “0” when the power is turned on, and is incremented by “1” when the random number of the special symbol data 1 is rewritten to “0”, and reaches “11”. Then, it is rewritten to “0” and the addition is repeated again. Further, the random number of the special symbol data 3 starts from “0” when the power is turned on or after the reset process, and is incremented by “1” when the random number of the special symbol data 2 is rewritten to “0”. When it reaches', then it is rewritten to '0' and the addition is repeated again. Thereby, even if the random number ranges of the special symbol data 1 to 3 are the same, the random numbers of the special symbol data 1 to 3 can be prevented from being synchronized (added in the same combination).

  Each random number of the special symbol data 1 to 3 is “1” if it is “0”, “1” if it is “1”, “2” if it is “2”, etc. Identification information consisting of a left special symbol, a middle special symbol, and a right special symbol, which are stopped and displayed on the display device 10 when they are off, is assigned. The random numbers of the special symbol data 1 to 3 are acquired due to winning in the upper starting winning port 41 or the lower starting winning port 42, and when the special symbol data 1 to 3 are combined, Identification information including a left special symbol, a middle special symbol, and a right special symbol displayed on the display device 10 is determined.

  The variation pattern random number counter is used when the variation pattern of the effect on the display device 10 is selected from the variation pattern table, and includes variation pattern random numbers of “0” to “198”. The random number value of the fluctuation pattern starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 for each of the normal symbol / special symbol main random number update processing to be described later. It is set to “0” and the addition is repeated again. The variation pattern random value is acquired due to winning in the upper start winning opening 41 or the lower start winning opening 42.

  A plurality of variation pattern tables are provided. In this embodiment, there are provided four types of variation pattern tables including a first variation pattern table, a second variation pattern table, a third variation pattern table, and a fourth variation pattern table. Each variation pattern table includes a plurality of variation patterns to be displayed on the display device 10 and is stored in the ROM of the main control board 200. In the present embodiment, the variation pattern is selected from the variation pattern table selected according to whether the gaming state is the probability variation state or the normal state, and whether the determination result is a hit or wrong. One variation pattern is selected based on the pattern random value. A variation pattern random value is assigned to each variation pattern, and a variation pattern corresponding to the acquired variation pattern random value is selected. A variation time is set for each variation pattern, and a special symbol variation / stop display mode (including the variation time of the special symbol) displayed on the display device 10 in accordance with the set variation time and the special symbol The background, characters, characters, and other effects to be displayed during or after the change are determined.

  The acquired jackpot random number value, jackpot symbol random number value, reach random number value, and variation pattern random number value are stored in correspondence with the number of reserved balls in a corresponding area in the RAM of the main control board 200, respectively. Used sequentially.

  The normal symbol random number counter is used for determination per ordinary symbol, has a normal symbol random number of “0” to “299”, and starts from “0” when the gaming machine 1 is turned on. “1” is added for each normal symbol / special symbol main random number update process, and when it reaches “299”, it is rewritten to “0” and the addition is repeated again. The normal symbol random numbers are acquired every time the normal symbol variation start switch detects a game ball that has passed through the normal symbol variation start gate 55, and up to four normal symbol random numbers in the RAM of the main control board 200. Stored in the storage area. The value of the normal symbol random number acquired due to the passing of the game ball through the normal symbol variation start gate 55 is set to “5” (1/300) as the established value per normal symbol in the low probability state. If it matches the probability of “0” to “59” (1/5) set as a numerical value established per normal symbol in the probability variation (high probability) state, Usually per symbol. In the case of per normal symbol, “O” is displayed on the normal symbol display device 50, and the lower start winning opening 42 is released according to whether or not it is in the certain change state, and the release time is released. If the normal symbol random number value does not match the established value per normal symbol, it is out of the normal symbol and "x" is displayed on the normal symbol display device 50, and the lower start winning opening 42 is in a state where it is difficult to win. Leave.

The opening detection of the front frame W2 and the glass door G in the gaming machine 1, power-on, and the subsequent game will be briefly described.
The gaming machine 1 is in a state where the front frame W2 and the glass door G are closed and locked by a key, for example, during the closing time of the gaming store. During the power-off state, backup power is supplied to the opening / closing detection switch 278 and the opening / closing detection storage unit 201, and the opening / closing detection state can be stored by detecting the opening / closing of the front frame W2 and the glass door G. . When the front frame W2 or the glass door G is opened in the power-off state, the opening / closing detection switch 278 detects the opening, and a detection signal is input to the opening / closing detection storage unit 201 and output to the CPU input port 202. The signal (1Q) changes from “L” to “H”, and the signal level “H” of the output signal (1Q) is held (stored) in the open / close detection storage unit 201.

  When the gaming machine 1 is turned on, it is locked when a gaming machine related person such as an administrator inserts a key into the key hole 6 of the front frame W2 and rotates the gaming machine 1 in one direction. The state is released, the front frame W2 is opened with respect to the outer frame W1 by pulling the right side of the front frame W2 forward and rotating the front frame W2, and is provided on the back side of the front frame W2. The game machine 1 may be turned on by pressing the power switch 272 or by turning on the power of the installation device itself in which the game machine is installed. In addition, when turning on / off the gaming machine 1 with the power supply of the gaming machine installation device itself, the power switch of the gaming machine 1 is turned on and the power supply of the installation device is switched on / off. . In addition, when opening of the glass door G is necessary, in the direction opposite to the case where a gaming machine related person such as an administrator inserts a key into the key hole 6 of the front frame W2 to open the front frame W2. The locked state is released by rotating, and the glass door G can be opened by rotating the front glass door G by pulling the right side of the glass door G forward.

When the gaming machine 1 is powered on, each device starts operating, and the output signal (1Q) stored in the open / close detection storage unit 201 is input to an input port of a CPU (main control unit), The signal level of the output signal (1Q) is confirmed. When the signal level of the output signal (1Q) stored (held) in the opening / closing detection storage unit 201 is “H”, notification is made by the display device 10, the lamp device 35, or a notification means such as a speaker. The game store can recognize that the front frame W2 or the glass door G has been opened in the power-off state.
After a predetermined time has elapsed, a clear signal is input from the CPU output port 204 of the main control board 200 to the HC 74 of the open / close detection storage unit 201 to clear the HC 74, and the output signal (1Q) changes from “H” to “L”. Thus, the open / close detection storage unit 201 is returned to the initial state.

  In the game of the gaming machine 1 after the power is turned on, when the game balls launched by the launching device 64 toward the game area 6 win the various winning holes, a predetermined number of gaming balls corresponding to the winning holes become prize balls. The payout device 281 pays out the upper ball receiving tray 36. Further, when the game ball passes through the normal symbol variation start gate 55, a normal symbol random number is acquired, and the normal symbol display device 50 determines the normal symbol per unit based on the acquired random number value. Starts to fluctuate and stops after fluctuating for a predetermined time. At that time, if the determination result per normal symbol is a win, it stops at the normal symbol, “◯” in this example, and the two movable pieces 42a and 42b of the lower start winning port 42 are on the back side. The closed solenoid (normal state), which is almost vertical and difficult to win, is changed from the closed solenoid (normal state) to the open state in which a winning is possible with a V shape (reverse C shape). In the case of the probability variation state, when it comes to the normal symbol, the lower start winning opening 42 is opened for 2 seconds three times. On the other hand, in the case of the low probability state, it is released for 1 second. Is performed once. When a game ball wins the lower start winning opening 42, a predetermined number of game balls are paid out as a prize ball.

  Further, when a game ball is won in the upper start winning opening 41 or the lower start winning opening 42, if the number of special symbol reserved balls is less than 4, the special symbol reserved ball number is incremented by 1 to obtain a jackpot random number value and a jackpot. A random number value such as a design random number value, a reach random number value, or a variation pattern random number value is acquired and stored in the RAM of the main control board 200 until a maximum of four is reached. And if the number of special symbol reservation balls memorize | stored in RAM of the said main control board 200 is one or more, while determining the success / failure of jackpot based on the previously acquired jackpot random value, One variation pattern is selected from the variation pattern table based on the pattern random value. Then, based on the selected variation pattern, the display device 10 starts an effect including the variation display of the special symbol. In the present embodiment, the number of the special symbol reserved balls is subtracted from the RAM of the main control board 200 by performing a special symbol variation display based on the result of the determination.

  The special symbol is stopped and displayed on the display device 10 when the variation time set for the selected variation pattern elapses (end of the variation time). If the result of the determination is wrong, the left special symbol, middle special symbol, and right special symbol are disengaged on the display device 10 and stop in a combination of symbols (a state other than a slotted pattern), and the game shifts to a jackpot game (special game). There is nothing. If the number of special symbol reservation spheres stored in the RAM of the main control board 200 is 1 or more, the jackpot random number value is acquired again in the same manner as described above, and the jackpot random number value is obtained based on the acquired jackpot random number value. In addition to the determination of whether or not, a variation pattern is selected from the variation pattern table based on the determination result and the variation pattern random value, and the display device 10 includes a variation display of a special symbol based on the selected variation pattern. Production is performed. If the number of special symbol reservation balls stored in the RAM of the main control board 200 is 0, then a game ball wins the upper start winning port 41 or the lower start winning port 42, and the Until the number of special symbol reservation balls stored in the RAM of the main control board 200 once becomes 1 or more, the determination of success / failure and the variation display of the special symbol are not performed.

  On the other hand, when the determination result is a big hit, the left special symbol, the middle special symbol, and the right special symbol are stopped on the display device 10 in combination with the big hit symbol (in the present embodiment, the slotted symbol), and the big hit game (special (Game).

  In the big win game (special game) state, the open / close plate 46 of the big prize opening 45 is opened to make it easy to receive the game balls falling on the surface of the game area 6, and the prize winning hole 45 can be awarded, When there is a prize at the big prize opening 45, a predetermined number of game balls are paid out as prize balls. The opening / closing plate 46 is closed after a predetermined time (for example, 15 seconds) or when the number of winning balls reaches a predetermined number (for example, 10), and the opening / closing plate 46 is repeatedly opened and closed for 15 rounds.

  After the jackpot game (special game) is over, if the number of special symbol reservation balls stored in the RAM of the main control board 200 is 1 or more, the jackpot random number is obtained again based on the jackpot random number value obtained in the same manner as described above. In addition to the determination of whether or not, a variation pattern is selected from the variation pattern table based on the determination result and the variation pattern random value, and the display device 10 includes a variation display of a special symbol based on the selected variation pattern. Production is performed. If the number of special symbol reservation balls stored in the RAM of the main control board 200 is 0, then a game ball wins the upper start winning port 41 or the lower start winning port 42, and the Until the number of special symbol reservation balls stored in the RAM of the main control board 200 once becomes 1 or more, the determination of success / failure and the variation display of the special symbol are not performed.

  In this embodiment, the display device 10 is specially combined with a normal jackpot symbol combination consisting of even numbers such as “0, 0, 0”, “2, 2, 2”, “4, 4, 4”. When a symbol is stopped and displayed, it is usually a big jackpot, and after the jackpot game (special game) is finished, the jackpot probability is low ((2/630 (1/315) in this example)) until the next jackpot. On the other hand, a special symbol is displayed on the display device 10 by a combination of probability variation jackpot symbols composed of odd numbers such as “1, 1, 1”, “3, 3, 3”, “5, 5, 5”, etc. When the stop display is made, it becomes a promising jackpot, and after the jackpot game (special game) ends, the probability of jackpot is set to a high probability (in this embodiment (12/630 (6/315)) until the next jackpot. Furthermore, the opening (expansion) time of the lower start winning opening 42 The number of times that the lower start winning opening 42 is opened (expanded) is increased from 1 to 3 in the low probability (normal) state, and is increased from 1 to 3 in the low probability (normal) state. The probability per normal symbol increases from 1/300 to 1/5 of the low probability (normal) state.

  When the front frame W2 or the glass door G is opened during the power-on state, it is detected by the opening detection switch 278 and notified by the notification means such as the display device 10, the lamp device 35, or the speaker 38, The game store can recognize that the front frame W2 or the glass door G has been opened.

  The control process in the gaming machine 1 will be described below. Examples of main flags provided in the control circuit of the main control board 200 include a big hit flag, a big hit end flag, a probability change flag, and the like in this embodiment. These flags are all turned off (= 0) at the initial setting.

  When a gaming machine related person such as an administrator pushes the power switch 272 provided on the back side of the front frame W2 to turn on the gaming machine 1, the main control board 200 is stored in the ROM. The CPU performs the main process M shown in FIG. 8 according to the control program (main control procedure).

In the main process M, an initial setting process (S10) for the CPU or the like is first performed. In the initial setting process (S10) of the CPU and the like, stack setting, interrupt time setting, CPU setting, SIO, PIO, CTC setting and the like are performed.
Next, in order to confirm the storage state of the open / close detection storage unit 201 during the power-off state in which power supply to the CPU (main control unit) of the main control board 200 is interrupted, the open / close detection storage unit 201 The signal level of the output signal (1Q) output to the CPU input port of the main control board 200 is confirmed (S20). The level of the output signal (1Q) changes from “L” to “H” as described above when the open detection switch 278 detects the opening of the front frame W2 or the glass door G in the power-off state. The signal level is held (stored). As a result of the confirmation, if the output signal (1Q) is “H”, the setting of the power-off open notification and the notification time (for example, 30 seconds) is performed (S30). In the setting of the notification of opening when the power is cut off, the setting for performing notification by the notification means including the speaker 38, the display device 10, the lamp device 35, and the like is performed. S20 to S30 correspond to notification processing. Next, the door state (opening / closing state of the front frame and the glass door) is set to closed, and the opening detection time is set to the door detection timer (S40). On the other hand, when the output signal (1Q) is determined to be “L” in S20, the door state (opening / closing state of the front frame and the glass door) is set to closed, and the door detection timer sets the opening detection time. It is set (S40). The door detection timer is a timer for detecting whether the front frame W2 and the glass door G are open or closed for a predetermined time. In the door detection timer, the opening detection time or the closing detection time described later is set, and when the set detection time has not elapsed, the door detection timer is configured not to reliably recognize that the opening / closing state of the front frame W2 has changed. ing. In the present embodiment, since it is configured based on a closed state when the power is turned on, it is configured to be set to closed and an open detection time is set. The opening detection time is 0.5 seconds, for example, and the closing detection time is 1 second, for example. In order to reliably detect the closing of the front frame W2 and the glass door G, it is preferable to make the closing detection time longer than the opening detection time.

  After that, interrupt prohibition processing (S50), normal symbol / special symbol main random number update processing (S60), interrupt permission processing (S70) is performed, and interrupt processing is performed every 4 ms while loop processing is performed in the final processing ( S100) is executed.

Although the main process M is repeatedly performed, S10 to S40 are initial control procedures that are necessary only when the power is turned on, and are executed only in the first round and not thereafter.
In the interrupt prohibition process (S50), even if the interrupt process (S100) is entered every 4 msec, the interrupt is prohibited until the interrupt is permitted.
In the normal symbol / special symbol main random number update process (S60), various random numbers are added for each of the normal symbol / special symbol main random number update process (S60), and when the update range upper limit value of each random number is reached as described above, The value is returned to the minimum value and the addition is performed again. The updated random number is stored in the RAM of the main control board 200.
In the interrupt permission process (S70), permission is given to the interrupt process (S100) that enters every 4 msec.

  In the interrupt process (S100), as shown in FIG. 9, the output process (S101), the input process (S102), the security control process (S103), the normal symbol / special symbol main random number update process (S104), the start winning prize detection Processing (S105), normal operation processing (S106), special operation processing (S107), reserved ball number processing (S108), power-off monitoring processing (S109), and other processing (S110) are sequentially performed.

In the output process (S101), an output command (command signal) set in each process is transmitted to each control board.
In the input process (S102), signal input is performed when various sensors (switches) attached to the gaming machine 1 are detected.

  In the security control process (S103), as shown in FIG. 10, the door opening / closing detection process (S103-1) and other detection processes (S103-2) for winning, the magnetism and radio waves applied to the gaming machine 1, and the like. Is done.

  In the door opening / closing detection processing (S103-1), processing relating to door opening detection and closing detection in the power-on state is performed. In this embodiment, the “door” indicates the front frame W2 and the glass door G. In the door opening / closing detection process (S103-1), as shown in FIGS. 11 and 12, first, the currently set door state (the state of the front frame W2 and the glass door G) is closed (being closed). (S103-1-1). The confirmation of the door state is determined by the door state stored in the RAM of the main control board 200. When the door state is not a closed state (closed) but an open state (opened), it is confirmed whether the open / close detection switch 278 detects the opening of the front frame W2 or the glass door G (S103-). 1-2) When the open / close detection switch 278 detects the opening of the front frame W2 or the glass door G, a closing detection time (for example, 1 second) is set in the door detection timer (S103-1- 3) It is confirmed whether the value of the abnormality notification timer (remaining notification time) is 0 (S103-1-17). When the value of the abnormality notification timer is different from 0, 1 is subtracted from the value of the abnormality notification timer (S103-1-18), and the door opening / closing detection process (S103-1) is ended. On the other hand, when the value of the abnormality notification timer is 0, the notification time ends, an output signal is input from the CPU output port 204 to the HC 74 of the opening / closing detection storage unit 201, and the output signal (1Q ) Is changed from “H” to “L” (S103-1-19), and then the door opening / closing detection process (S103-1) ends. That is, it is configured to return to the original state once the notification time is over. The setting of the clear signal corresponds to initialization means for returning the opening / closing detection storage unit 201 to an initial state.

  If the opening / closing detection switch 278 does not detect the opening of the front frame W2 and the glass door G in S103-1-2, that is, if the closing is detected, the value of the door detection timer (remaining closing detection time) ) Is confirmed to be 0 (S103-1-4). If the value of the door detection timer (remaining closing detection time) is not 0, 1 is subtracted from the value of the door detection timer (remaining closing detection time) (S103-1-5), and then the value of the abnormality notification timer is reached. Is confirmed to be 0 (S103-1-17). When the value of the abnormality notification timer is different from 0, 1 is subtracted from the value of the abnormality notification timer (S103-1-18), and the door opening / closing detection process (S103-1) is ended. On the other hand, when the value of the abnormality notification timer is 0, the notification time ends, the clear signal is set (S103-1-19), and then the door opening / closing detection process (S103-1) is performed. finish.

  If the value of the door detection timer (remaining closing detection time) is determined to be 0 in S103-1-4, the door state (the state of the front frame W2 and the glass door G) is set to closed (S103-1- 6) The door closing command is set in the output buffer (S103-1-7). Next, an output signal is input from the CPU output port 204 to the HC 74 of the opening / closing detection storage unit 201 to output an output signal from the opening / closing detection storage unit 201. A clear signal for changing (1Q) from “H” to “L” is set (S103-1-8). That is, the open / close detection storage unit 201 stores and maintains the open detection state even in the power-on state, and is thus configured to return to the original state when the notification time ends. The setting of the clear signal in S103-1-8 corresponds to initialization means for returning the opening / closing detection storage unit 201 to an initial state. Thereafter, an opening detection time (for example, 0.5 seconds) is set in the door detection timer (S103-1-9), and it is confirmed whether the value of the abnormality notification timer is 0 (S103-1-17). When the value of the abnormality notification timer is different from 0, 1 is subtracted from the value of the abnormality notification timer (S103-1-18), and the door opening / closing detection process (S103-1) is ended. On the other hand, when the value of the abnormality notification timer is 0, the notification time ends, the clear signal is set (S103-1-19), and then the door opening / closing detection process (S103-1) is performed. finish. The door closing command is output to the sound control board 220 in the output process (S101), and the opening notification performed by the speaker 38 is terminated.

  On the other hand, if it is determined in S103-1-1 that the current setting of the door state is the closed state (closed), it is confirmed whether the open / close detection switch 278 detects the closing of the front frame W2 and the glass door G. (S103-1-10), when the opening / closing detection switch 278 detects closing, an opening detection time (for example, 0.5 seconds) is set in the door detection timer (S103-1-11), and thereafter It is confirmed whether the value of the abnormality notification timer is 0 (S103-1-17). In this embodiment, since the closed state is set when the power is turned on, the processing from S103-1-1 to S103-1-10 is executed, and the processing changes depending on the state of the open / close detection switch 278 at that time. It is configured. When the value of the abnormality notification timer is different from 0, 1 is subtracted from the value of the abnormality notification timer (S103-1-18), and the door opening / closing detection process (S103-1) is ended. On the other hand, when the value of the abnormality notification timer is 0, the notification time ends, the clear signal is set (S103-1-19), and then the door opening / closing detection process (S103-1) is performed. finish.

  When the door switch does not detect the closing of the front frame W2 and the glass door G in S103-1-10, that is, when the opening is detected, the value of the door detection timer (remaining opening detection time) is 0. (S103-1-12). If the value of the door detection timer (remaining opening detection time) is not 0, 1 is subtracted from the value of the door detection timer (remaining opening detection time) (S103-1-13), and then the value of the abnormality notification timer is reached. Is confirmed to be 0 (S103-1-17). When the value of the abnormality notification timer is different from 0, 1 is subtracted from the value of the abnormality notification timer (S103-1-18), and the door opening / closing detection process (S103-1) is ended. On the other hand, when the value of the abnormality notification timer is 0, the notification time ends, the clear signal is set (S103-1-19), and then the door opening / closing detection process (S103-1) is performed. finish.

  When it is determined in S103-1-12 that the value of the door detection timer (remaining opening detection time) is 0, the door state (the state of the front frame W2 and the glass door G) is set to open (S103-1- 14) A door opening command is set in the output buffer (S103-1-15), a closing detection time (for example, 1 second) is set in the door detection timer (S103-1-16), and then an abnormality notification timer is set. It is confirmed whether the value is 0 (S103-1-17). When the value of the abnormality notification timer is different from 0, 1 is subtracted from the value of the abnormality notification timer (S103-1-18), and the door opening / closing detection process (S103-1) is ended. On the other hand, when the value of the abnormality notification timer is 0, the notification time ends, the clear signal is set (S103-1-19), and then the door opening / closing detection process (S103-1) is performed. finish. The door opening command is output to the voice control board 220 in the output process (S101), and the speaker 38 is notified of opening.

  In the normal symbol / special symbol main random number update process (S104), the same process as the normal symbol / special symbol main random number update process (S40) performed in the loop process in the main process M is performed.

  In the start winning opening detection process (S105), as shown in FIG. 13, it is determined whether a winning to the upper start winning opening 41 or the lower start winning opening 42 is detected (S105-1), and a winning is detected. If not, it is determined whether or not a game ball passage to the normal symbol variation start gate 55 is detected (S105-2). When the passing of the game ball to the normal symbol variation start gate 55 is not detected, the start winning opening detection process (S105) is ended. On the other hand, when the passing of the game ball to the gate 55 is detected, it is determined whether the number of the normal symbol holding balls is 4 or more (S105-3), and if it is 4 or more, the start winning opening detection process (S105). Ends. On the other hand, if the number of retained ordinary symbol balls is less than 4, 1 is added to the number of retained ordinary symbol balls (S105-4), the ordinary symbol random number value is acquired, and the acquired ordinary symbol random number value is stored in the RAM of the main control board 200. (S105-5). This start winning opening detection process (S105) ends.

  If it is determined in S105-1 that a winning in the upper starting winning port 41 or the lower starting winning port 42 has been detected, it is determined whether the number of special symbol reservation balls is 4 or more (S105-6). In this case, the start winning opening detection process (S105) ends. On the other hand, if the number of special symbol reserve balls is less than 4, the special symbol reserve ball number is incremented by 1 (S105-7), and special jackpot random numbers, jackpot symbol random values, reach random numbers, fluctuation pattern random numbers, etc. A special symbol related random number acquisition process for acquiring the symbol related random number and storing it in the corresponding area of the RAM of the main control board 200 is performed (S105-8), and the start winning opening detection process (S105) is completed.

  In the normal operation process (S106), as shown in FIG. 14, it is first confirmed whether or not the lower start winning opening 42 is open (S106-1). If the lower start winning opening 42 is closed, it is confirmed that the number of normal symbol reserved balls is 0 (S106-2), and if it is 0, the normal operation process (S106) is ended. On the other hand, when the number of normal symbol holding balls is not 0, it is acquired by the normal symbol random number acquisition process (S105-5) of the start winning opening detection process (S105) and stored in the RAM of the main control board 200. The acquired normal symbol random value is read (S106-3), and it is confirmed whether the current probability change is in progress (the probability change flag is ON) (S106-4). If it is not probabilistic, the acquired normal symbol random number value is compared with the established value per normal symbol in the low probability state to check whether they match, and if they match, it corresponds to the normal symbol in the low probability state and matches If not, it is determined that it is off (S106-5). If it is off, this normal operation process (S106) ends. On the other hand, if it is per normal symbol, the starting start opening that opens the lower start winning opening 42 with an opening time of 1 second and 1 opening is opened. Process 1 is performed (S106-6), and thereafter, the normal operation process (S106) ends. On the other hand, when it is determined in S106-4 that the probability change is in progress, the acquired normal symbol random number value is compared with the established value per normal symbol in the high probability state, and it is confirmed whether or not both match. It is per ordinary symbol in the probability state, and if it does not match, it is determined that it is off (S106-7). If it is off, the normal operation process (S106) is completed. On the other hand, if it is per normal symbol, the lower start winning opening 42 is opened with an opening time of 2 seconds and an opening number of 3 times. Process 2 is performed (S106-8), and thereafter, this normal operation process (S106) ends.

  If it is determined in S106-1 that the lower start winning opening 42 is being opened, it is confirmed whether or not the opening time of the lower start winning opening 42 has elapsed (finished) (S106-9), and the start winning opening opening time is determined. When the time has not elapsed, the normal operation process (S106) ends. On the other hand, when the start winning opening opening time has elapsed, a process of closing the lower starting winning opening 42 is performed (S106-). 10) Thereafter, the normal operation process (S106) is completed.

  In the special operation process (S107), as shown in FIG. 15, it is determined which of the special operation status is 1 to 4 (S107-1 to S107-3). When the special operation status is 1, a special symbol standby process (S107-4) is performed. When the special operation status is 2, a changing process (S107-5) is performed, and the special operation status is In the case of 3, a special symbol determination process (S107-6) is performed, and in the case where the special operation status is 4, a special electric accessory process (S107-7) is performed.

  In the special symbol standby process (S107-4) performed when the special operation status is 1, as shown in FIG. 16, it is determined whether or not the number of special symbol reservation balls is 0 (S107-4-1), and the special symbol is determined. When the number of held balls is 0, it is determined whether or not the display device 10 is on a standby screen (standby screen) where the special symbol is not changing (S107-4-9). Then, the special symbol standby process (S107-4) is completed. On the other hand, when it is not in the standby screen (standby screen), a standby screen setting process for making the display device 10 the standby screen (standby screen) is performed (S107-4-10), and then set in the standby state. (S107-4-11), and then the special symbol standby process (S107-4) is completed. The setting process for setting the standby screen is a command for setting the standby screen when a game ball does not win the upper start winning opening 41 or the lower starting winning opening 42 for a predetermined time after the setting process is performed. Is a process for outputting.

  On the other hand, if it is determined in S107-4-1 that the number of special symbol reservation balls is not 0, special symbol jackpot determination processing (S107-4-2) is performed.

  In the special symbol jackpot determination process (S107-4-2), as shown in FIG. 17, first, the main control is acquired by the special symbol-related random number acquisition process (S105-8) of the start winning opening detection process (S105). The jackpot random number value stored in the RAM of the substrate 200 is read (S107-4-2-1), and then it is confirmed whether the current probability is changing (high probability state) (S107-4-2-2). Whether or not the probability change is in progress is determined to be in the probability change state when the probability change flag is ON, and on the other hand, when the probability change flag is OFF, it is determined to be a low probability state in which the probability change is not in progress. In the case of a low-probability state that is not probabilistic, the acquired jackpot random number value is compared with the jackpot value in the low-probability state to check whether they match. If not, it is determined that it is off (S107-4-2-3). In the case of losing, this special symbol jackpot determination process (S107-4-2) is terminated, while in the case of jackpot, the jackpot flag is set to ON (S107-4-2-5), and thereafter This special symbol jackpot determination process (S107-4-2) ends. On the other hand, if it is determined in S107-4-2-2 that the probability change is high (high probability state), the acquired jackpot random number value is compared with the jackpot value in the high probability state to confirm whether they match. If they match, it is a big hit in the high probability state, and if they do not match, it is determined that they are off (S107-4-2-4). In the case of losing, this special symbol jackpot determination process (S107-4-2) is terminated, while in the case of jackpot, the jackpot flag is set to ON (S107-4-2-5), and thereafter This special symbol jackpot determination process (S107-4-2) ends. This special symbol jackpot determination process (S107-4-2) corresponds to a winning / failing determination means.

Following the special symbol jackpot determination process (S107-4-2), a special symbol selection process (S107-4-3) is performed.
In the special symbol selection process (S107-4-3), a combination of special symbols to be stopped and displayed on the display device 10 is determined. In the special symbol selection process (S107-4-3), as shown in FIG. 18, it is first determined whether or not the jackpot flag is ON (S107-4-3-1). A special symbol based on the jackpot symbol random number is set as a stop special symbol (S107-4-3-3). On the other hand, if the jackpot flag is not ON, that is, if it is off, a special symbol data random value (special symbol data 1, special symbol data 2, special symbol data 3) is acquired (S107-4-3-3), It is determined whether the random numbers of the special symbol data 1, the special symbol data 2 and the special symbol data 3 are all matched (S107-4-3-3-4). (S107-4-3-5). When the reach random number value matches the reach establishment value, the reach is present, and the special symbol assigned to the random value of the special symbol data 1 is added to the random number value of the stop left special symbol and the special symbol data 2 The special symbol assigned to the random number value is set to the special symbol for stopping, and the special symbol assigned to the random value of the special symbol data 3 is set to the special symbol for stopping right (S107-4-3-6). On the other hand, if the reach random number value does not match the reach establishment value, no reach is reached, and the special symbol assigned to the random value of the special symbol data 1 is changed to the random number value of the left special symbol and the special symbol data 2 The special symbol assigned is the special symbol for stoppage, and the special symbol assigned to the random value obtained by adding 1 to the random value of the special symbol data 3 is set as the special symbol for stop right (S107-4-3-7). .

  If it is determined in S107-4-3-3-4 that the random numbers of the special symbol data 1, 2 and 3 do not match, it is determined whether the random values of the special symbol data 1 and 3 match. (S107-4-3-8). If the random numbers of the special symbol data 1 and 3 match, it is determined whether the reach random number value matches the reach establishment value (S107-4-3-9). If the reach random number value matches the reach establishment value, the reach is present, and the special symbol assigned to the random value of the special symbol data 1 is assigned to the random number value of the stop left special symbol and the special symbol data 2 The special symbol assigned to the random symbol value of the special symbol data 3 which is the special symbol being stopped and the special symbol data 3 is set to the special symbol for the stop right (S107-4-3-10). On the other hand, if the reach random number value does not match the reach establishment value, no reach is reached, and the special symbol assigned to the random value of the special symbol data 1 is changed to the random number value of the left special symbol and the special symbol data 2 The special symbol assigned is the special symbol for stoppage, and the special symbol assigned to the random value obtained by adding 1 to the random value of the special symbol data 3 is set as the special symbol for stop right (S107-4-3-7). .

  If it is determined in S107-4-3-8 that the random numbers of the special symbol data 1 and 3 do not match, that is, the special symbol data 1, 2, and 3 are all different, the reach random number value is established. It is determined whether or not it matches the numerical value (S107-4-3-11). When the reach random number value matches the reach establishment value, the reach is present, and the special symbol assigned to the random value of the special symbol data 3 is set as the stop left special symbol and the stop right special symbol, The special symbol assigned to the random number value obtained by adding 1 to the random number value of the special symbol data 3 is set as the special symbol during stoppage (S107-4-3-12). On the other hand, if the reach random number value does not match the reach establishment value, no reach is reached, and the special symbol assigned to the random value of the special symbol data 1 is changed to the random number value of the left special symbol and the special symbol data 2 The assigned special symbol is set to the stopped special symbol, and the special symbol assigned to the random value of the special symbol data 3 is set to the stopped right special symbol (S107-4-3-10).

After the special symbol selection process (S107-4-3), a special symbol variation pattern selection process (S107-4-4) is performed.
In the special symbol variation pattern selection process (S107-4-4), one variation pattern table is selected from a plurality of variation pattern tables based on the determination result, and one variation is selected from the selected variation pattern table according to the variation pattern random value. A pattern variation command is selected. Further, it is assumed that a detailed effect mode may be selected on the sub control board 205 based on the fluctuation pattern selected by the special symbol fluctuation pattern selection process of the main control board 200.

  In the special symbol variation pattern selection process (S107-4-4), as shown in FIG. 19, it is first determined whether or not the probability variation is in progress (high probability state) (S107-4-4-1). In the case of a normal state (low probability state) that is not under certain change, it is determined whether or not the big hit flag is ON (big hit) (S107-4-4-2). When the big hit flag is ON (big hit), a fluctuation command of one fluctuation pattern per normal state is selected from the first fluctuation pattern table based on the fluctuation pattern random value (S107-4-4-3). . On the other hand, when the jackpot flag is OFF (disconnected), a variation command of one variation pattern out of the normal state is selected from the second variation pattern table based on the variation pattern random value (S107-4-4). 4).

  On the other hand, if it is determined in S107-4-4-1 that the probability change is in progress (high probability state), it is determined whether or not the big hit flag is ON (big hit) (S107-4-4-5). When the big hit flag is ON (big hit), the fluctuation command of one fluctuation pattern per probability variation is selected from the third variation pattern table based on the variation pattern random value (S107-4-4-6). . On the other hand, when the big hit flag is OFF (disconnected), a variation command of one variation pattern that is out of probability variation is selected from the fourth variation pattern table based on the variation pattern random value (S107-4-4). 7).

  After selecting the variation command of the variation pattern, the selected variation command is stored in the transmission buffer (S107-4-4-8), and other processing is performed (S107-4-4-9). The variation pattern selection process (S107-4-4) ends.

After the special symbol variation pattern selection process (S107-4-4), a special symbol random number shift process (S107-4-5) is performed.
In the special symbol random number shift process (S107-4-5), in the data storage area of the special symbol reservation ball number in the RAM, the number of special symbol reservation balls stored in the storage area of the load (read) rank first place address. Due to the fact that this data is loaded in the previous process and becomes vacant, the address that advances the loading order one by one with respect to the data of the number of special symbol holding balls stored in the second and subsequent addresses. Shifts are made. Specifically, as shown in FIG. 20, first, 1 is subtracted from the number of special symbol reserved balls stored in the RAM of the main control board 200 (for example, the number of reserved balls of 2 is set to 1 and 3 (S107-4-5-1), and then the data corresponding to each number of reserved balls is shifted to the RAM address of the number of reserved balls obtained by subtracting 1 from each number of reserved balls (S107- 4-5-2) Subsequently, 0 is set to the RAM address corresponding to the number of special symbol reservation balls (the last in the loading order, the fourth in this embodiment) (S107-4-5-3). ).

Subsequent to the special symbol random number shift process (S107-4-5), a special symbol variation start process (S107-4-6) is performed. In the special symbol variation start process (S107-4-6), processing necessary for starting the special symbol variation is performed.
After the special symbol variation start process (S107-4-6), the special operation status is set to 2 (S107-4-7), the waiting state is canceled (S107-4-8), and the special symbol standby is performed. The process (S107-4) ends.

  In the changing process (S107-5) performed when the special operation status is 2, as shown in FIG. 21, it is first determined whether or not the special symbol change time (change pattern change time) has ended (S107). -5-1) If the change time has not ended, the changing process (S107-5) ends. On the other hand, if the fluctuation time has ended, a fluctuation stop command is set (S107-5-2). Subsequently, after the special operation status is set to 3 (S107-5-3) and other necessary processing (S107-5-4) is performed, this in-fluctuation processing (S107-5) ends.

  In the special symbol determination process (S107-6) performed when the special operation status is 3, as shown in FIG. 22, it is first determined whether or not the big hit flag is ON, that is, whether or not the big hit flag is set (S107-6). 1). When the jackpot flag is ON, that is, when the jackpot is successful, the jackpot command is stored in the transmission buffer (S107-6-2), and the special operation status is set to 4 (S107-6-3). The process (S107-6) ends. On the other hand, when the big hit flag is OFF, that is, it is off, the special operation status is set to 1 (S107-6-4), and this special symbol confirmation process (S107-6) is completed.

  The special electric accessory process (S107-7) performed when the special operation status is 4 corresponds to a jackpot game execution means. In the special electric accessory processing (S107-7), as shown in FIG. 23 and FIG. 24, first, the probability variation flag is turned OFF (S107-7-1), and it is confirmed whether or not the big hit opening is performed on the display device 10. (S107-7-2). When the jackpot opening is not performed, the jackpot opening is performed (S107-7-3), and then it is determined whether or not the jackpot end flag is ON (the jackpot game end) (S107-7-4). On the other hand, if the jackpot opening has been performed, it is next determined whether or not the jackpot end flag is ON (the jackpot game ends) (S107-7-4).

  When the jackpot end flag is not ON, that is, when the jackpot game is not ended, it is determined whether or not the big prize opening 45 is currently open (S107-7-5). It is determined whether or not it is the opening time of the mouth 45 (S107-7-6). In the case of the opening time of the special winning opening 45, the special winning opening process is performed (S107-7-7), and then the special electric accessory process (S107-7) is completed. On the other hand, when it is not the opening time of the special winning opening 45, the special electric accessory processing (S107-7) is ended.

  On the other hand, if it is determined in S107-7-5 that the big prize opening 45 is open, ten game balls are won in the big prize opening 45 (S107-7-8), or the round end time (in this embodiment). 30 seconds), it is determined whether or not it has passed (S107-7-9). If it is not, the special electric accessory processing (S107-7) is terminated as it is, and a special prize opening is received. In the case where 10 game balls in 45 are either winning or the round end time has elapsed, the big winning opening closing process (S107-7-10) and the process of subtracting 1 from the value of the round counter (S107-7- 11) is performed. In the special winning opening closing process (S107-7-10), a special winning opening closing command is set in the output buffer. Subsequently, it is determined whether or not the round counter is 0 (S107-7-12). If the round counter is not 0, the special electric accessory processing (S107-7) is finished as it is, and the round counter is processed. When the counter is 0, the jackpot end process (S107-7-13) is performed. In the jackpot end process, preparation for ending is performed, and then the jackpot end flag is turned ON (S107-7-14), and this special electric accessory process (S107-7) ends.

  On the other hand, when the jackpot end flag is turned on in S107-7-4, that is, when it is determined that the jackpot game ends, the processing for setting the jackpot end flag to OFF (S107-7-15) and the jackpot flag are turned OFF. The process (S107-7-16) is performed, and then it is confirmed whether the stop special symbol is a probable variation symbol (odd tick) (S107-7-17), and the stop special symbol is a probabilistic variation symbol The probability variation flag is turned on (S107-7-18). On the other hand, when the special symbol for stoppage is not a probability variation symbol but a normal symbol (even numbers), the probability variation flag is turned off (S107-7-). 19) After that, the special operation status is set to 1 (S107-7-20), and this special electric accessory processing (S107-7) is completed.

  Following the special operation process (S107), a reserved ball number process (S108) is performed. In the reserved ball number process (S108), as shown in FIG. 25, the current reserved ball number is loaded (S108-1), and the reserved ball number is set in the output buffer (S108-2).

  In the power-off monitoring process (S109) performed after the reserved ball number process (S108), as shown in FIG. 26, it is determined whether a power-off signal is input (S109-1), and the power-off signal is input. If not, the power-off monitoring process (S109) ends. On the other hand, when the power-off signal is input, each register and stack pointer are saved, the output port is cleared (the operation of the accessory is stopped), and when the RAM clear switch 271 is not operated, The current data (game state) is stored in the RAM of the main control board 200, and the 1-byte value obtained by adding all the RAM areas is inverted and stored in the backup guarantee value (S109-2). A power-off flag indicating that the power-off process has been normally completed is set to ON (S109-3), and thereafter, a state is just waited for the power to be turned off (infinite loop). The data (gaming state) stored in the RAM of the main control board 200 includes, for example, data during display standby, symbol variation, symbol fixed display, jackpot game, and the like. There is data for a high probability state) and a normal state (low probability state).

  In the other process (S110) performed after the power-off monitoring process (S109), various other processes necessary for the game are performed. However, the description of the process not particularly related to the present invention is omitted.

  Processing performed by the sub control board 205 will be described. In the sub control board 205, as shown in FIG. 27, the CPU initialization process is performed in the sub control board 205 when the gaming machine 1 is turned on (S201). In the CPU initialization process (S201), settings for the external INT interrupt (reception interrupt) process (S300), the 2 ms timer interrupt process (S400), and the 10 ms timer interrupt process (S500) are performed. Next, it is determined whether the power-off signal is ON and the contents of the RAM are normal (S202). If the power-off signal is not ON, or if the power-off signal is ON and the contents of the RAM are not normal, such as when the power-off signal is not normal and the contents of the RAM are normal, the RAM is initialized (S203). Thereafter, the watchdog timer counters 1 and 2 are initialized (S204). On the other hand, when both the power-off signal ON and the normal contents of the RAM are satisfied, the watchdog timer counters 1 and 2 are initialized without initializing the RAM (S204). The processes of S201 to S204 are executed only in the first order when the power is turned on, and are not executed thereafter.

  After the initialization of the watchdog timer counters 1 and 2 (S204), the interrupt is disabled in the loop processing (S205), the random number seed update (S206), the command transmission processing (S207), the watchdog timer counter 1 initialization (S208), Interrupt permission (S209) is performed. Also, external INT interrupt processing (S300), 2 ms timer interrupt processing (S400), and 10 ms timer interrupt processing (S500) are performed during the loop processing.

In the interrupt prohibition (S205), even if an interrupt occurs, the interrupt is prohibited.
In random number seed update (S206), various random numbers are updated.
In the command transmission process (S207), various commands set in each process of the sub control board 205 are transmitted to the board and apparatus corresponding to the command.
In the initialization of the watchdog timer counter 1 (S208), the value of the watchdog timer counter 1 is initialized.
In interrupt permission (S209), execution of the interrupt is permitted.

  In the external INT interrupt processing (S300), as shown in FIG. 28, it is confirmed whether the strobe (STB) signal from the main control board 200 is ON (S301), and the strobe signal is ON, that is, the strobe signal is input to the external INT input unit. Is received, the command (control signal) output from the main control board 200 is received and stored in the RAM (S302). On the other hand, if the strobe signal is not ON, the external INT interrupt processing (S300) is completed at that time.

In the 2 ms timer interrupt process (S400), as shown in FIG. 29, a lamp data output process (S401), a SW / drive output process (S402), an input process (S403), and a watchdog timer process (S404) are performed.
In the ramp data output process (S401), the ramp data created in the 10 ms timer interrupt process is output.
In the SW / drive output process (S402), the valid period and operation output of the game operation switch 67 are performed.
In the input process (S403), switch edge data and level data are created.
In the watchdog timer process (S404), the watchdog timer is reset.

  In the 10 ms timer interrupt process (S500), as shown in FIG. 30, the switch state acquisition process (S501), the voice control process (S502), the main command analysis process (S503), the SW process (S504), and the lamp process (S505). Is done.

In the switch state acquisition process (S501), the switch data created in the 2ms timer interrupt process (S400) is stored as switch data for the 10ms timer interrupt process.
In the sound control process (S502), a process for sound emitted from the speaker 38 is performed.
In the main command analysis process (S503), an analysis process for all commands received in the external INT interrupt process (S300) and an operation according to the received command are set.
In the SW process (S504), the effective time (operation valid period) and operation of the game operation switch 67 are managed. In the ramp process (S505), the output ramp data is created and the production time is managed.

  As described above, in this embodiment, the detection result by the open / close detection means is stored in the open / close detection storage unit even when the power supply to the main control unit is interrupted, and the main control unit stores the open / close detection storage unit in the power-on state. Check the status, and if there is open memory in the open / close detection storage unit, notify the gaming machine that the power is turned off by notifying that at least one of the front frame or the transparent plate holding frame is open. It is possible to recognize that there is a possibility of fraud such as attaching a device, and it is possible to suppress the operation of the gaming machine in an unauthorized state.

The present invention is not limited to the above-described embodiments, and can be changed without departing from the spirit of the invention. For example, in the above-described embodiment, the front frame opening and the glass door (transparent plate holding frame) opening are notified without distinction, but are stored separately, for example, when the front frame is opened and the glass door is opened. Depending on the case, the sound volume, tone color, or notification means (speaker, display device, lamp device, etc.) may be made different.
Further, in the embodiment, when the power is turned off, the memory is opened when it is opened even once. However, for example, the number of times of opening may be memorized, or it may be memorized when opened plural times including two times or more. To do. If the number of times of opening is stored, the number of times of opening may be notified.
Further, in this embodiment, when the opening / closing detection switch 278 detects the opening of the front frame W2 or the glass door (transparent plate holding frame) G in the power-on state, the CPU input port 203 transfers to the CPU (main control unit). While the open detection signal is input, the output signal (1Q) to the CPU input port 202 is also changed from “L” to “H”, but the open / close detection signal from the CPU input port 203 is in the power-on state. Only the CPU (main control unit) may be input, and the output signal (1Q) for the CPU input port 202 may not be changed. In that case, the output signal (1Q) to the CPU input port 202 may be confirmed when the power is turned on, and the signal of the CPU input port 203 may be confirmed when the game is possible in the power-on state.
