The command signal for the control command is transmitted via the signal transmission path 500b as a command signal for which the voice / lamp control unit 170 is an operation command target.

  Note that the special symbol control unit 160 and the sound / lamp control unit 170 described above may be configured by the same circuit units as the main control unit 140 and the payout control unit 150. That is, a CPU that includes a main circuit portion and an input / output circuit portion and has a built-in ROM and RAM can also be used.

The prize ball operation is executed in the following order.
The main control unit 140 transmits a predetermined number of award ball number data to the payout control unit 150 via the signal transmission path 500a in the order of detection as a command signal for which the payout control unit 150 is an operation command target. The number of unique award balls is 6, 10, or 15 in the gaming machine 1. Specifically, 15 when the game ball passes the winning ball detection switch 318, 6 when the game ball passes the start opening winning detection switch 17s, and other cases (for example, the general winning ports 81 to 83) In the case where the passage of the passage detection switches 81s and 82s is detected, the number is 10). The payout control unit 150 receives the prize ball number data from the main control unit 140 and operates the prize ball payout device 109 by transmitting a prize ball payout signal.

  Further, the main control unit 140 determines a gaming state based on the outputs of the various detection switches described above. Further, the main control unit 140 determines whether or not the game is successful based on the gaming state and reads data for performing screen display control in a symbol display mode corresponding to the determination content. For example, the main control unit 140 uses the detection results of the start opening winning detection switch 17s, the winning ball detection switch 318, etc., the acquired value of the special symbol success / failure determination random number, and the like to wait for a customer who is not playing a game. Also, a state in which a game is played but no start prize is won (variable preparation state), a state in which a start prize has been won, and a special game state are also determined. In addition, when a start winning is detected, determination of success / failure is performed based on a random value described later, and for the display mode control such as change of special symbols (including reach display mode) or confirmation based on the determination result Data is read. This data is transmitted via the signal transmission path 500a as a command signal for which the special symbol control unit 160 is an operation command target.

  Next, jobs executed by the main control unit 140 will be described with reference to FIGS. FIG. 14 shows an example of a main job executed by the CPU 401 of the main control unit 140 based on a program stored in the ROM 482.

  First, the stack pointer is set to a predetermined address in the RAM 481 (S10), and it is determined whether or not the RAM clear switch 144 is operated (pressed) (S12). As a result, when the RAM clear switch 144 is operated, the RAM 481 is initialized (S800). On the other hand, when the RAM clear switch 144 is not operated, it is determined whether or not the backup flag is set (S15). As a result, when the backup flag is set, the “recovery processing for power interruption” shown in FIG. 16 is performed.

  Note that the gaming machine 1 performs the processing when the power interruption occurs as shown in the flowchart of FIG. 15 when the power interruption occurs due to a power failure or the like. First, the used register is saved in the RAM 481 (S630), and the value of the stack pointer is saved in the RAM 481 (S632). Then, the special winning opening solenoid 313 and the starting opening solenoid 17c are turned off (S634), and the polling processing time (for example, about 85 milliseconds) of the winning ball sensor is set (S636). The passage of the game ball is monitored by the sensor (S638). Next, when the polling processing time elapses (S640), a checksum (excluding checksum, backup flag, and stack area) of the RAM 481 used is created (S642), stored, and the backup flag is set in the RAM 481 ( S646). Then, access to the RAM 481 is prohibited (S648), and an infinite loop process prepares for power down. It is also possible to execute HALT processing or STOP processing instead of the unlimited loop processing.

  In the “return process” shown in FIG. 16, a checksum is calculated (S664), and it is determined whether or not it matches the checksum stored when the power is turned off (S666). As a result, if the checksums do not match, the RAM 481 is initialized (S800). On the other hand, if the checksums match, the stack pointer before power-off is restored (S668), the backup flag is cleared (S670), and a command for returning the sub-board to the state before power-off is transmitted. (S672). Then, each register is returned to the state before the power is turned off (S674), the permission / non-permission of the interrupt is returned to the state before the power is turned off (S676, S678), and the address is returned to the address before the power is turned off (S680). In this embodiment, since a backup power supply for power failure countermeasures is added to the gaming machine 1, "information advantageous to the player" that was generated before the power outage was saved even during a pachinko hall power outage, etc. it can.

  Returning to FIG. 14, if it is determined in step S15 that the backup flag is not set, the initialization end is determined (S20). As a result, if the initialization has not ended, the initialization end determination in S20 is performed again after executing the initialization job (S190). Note that the initialization process of the RAM 481 is performed when the gaming machine 1 is turned on for the first time from the shipment state, when the RAM clear switch 144 is operated (pressed), when the backup flag is abnormal, and when the checksum is one. If you did not do it.

  On the other hand, if the initialization has been completed, each job from the LED job (S30) to the switch job (S70) is executed. In the LED job (S30), the display pattern data of the normal symbol and the normal symbol unstarted count, the display pattern data of the special symbol unstarted count, and the like are output. In the constant speed random number job (S40), a special symbol success / failure random number memory, a general-purpose count memory, and the like of the RAM 481 described later are updated. In the non-constant speed random number job (S50), the initial value counter and the off-normal symbol random number memory (not shown) are updated. The general-purpose count memory (not shown) is used, for example, for creating values “0” to “255” for each interrupt, executing command jobs, and decoration jobs.

  In the voice job (S60), data related to music and voice is read, and in the switch job (S70), various detection switches are read. That is, various signals such as a winning opening passing detection signal are taken into the main control unit 140 via the relay board 190, and various signals such as a firing stop detection signal, a touch detection signal, and a volume detection signal are sent via the payout terminal board 191. Are taken into the frame control unit 150. In addition, the main control unit 140 receives a start port winning detection signal from the start port winning detection switch 17s, and receives a winning ball detection signal and a normal symbol operation gate passage detection signal from the large winning device 31.

  Next, it is determined whether or not there is an abnormality in various switches such as a count detection switch, a count detection and a specific area passage detection switch (S80). As a result, if there is an abnormality (ball clogging or disconnection), an error job (S130) is executed.

  On the other hand, if there is no abnormality, a special symbol main job (S90) and a normal symbol job (S100) are executed. In the special symbol main job (S90), a job related to data necessary for the main controller 140 and the special symbol controller 160 to operate in cooperation is executed. Further, in the normal symbol job (S100), the display pattern data of the normal symbol and the normal symbol unstarted number of times is read.

  Thereafter, the state of each flag is set in the backup memory (S140), and a prize ball signal job (S150), an information signal job (S160), a command job (S170), and a remaining time job (S180) are executed. In the prize ball signal job (S150), data relating to prize ball payout is read and output, and in the information signal job (S160), data necessary for outputting information to other control units is read. Further, in the command job (S170), a command for special symbol management or the like is output, and in the remaining time job (S180), a non-constant random number is called. The initial value random number is also updated in the remaining time job of S180.

  Next, the success / failure determination job executed in the series of the main job will be described with reference to the flowcharts of FIGS. FIG. 17 is a flowchart of the success / failure determination job, FIG. 18 is a flowchart of the jackpot process, and FIG. 19 is a flowchart of the miss process. The success / failure determination job is executed at the time of starting winning, that is, when winning at the starting port 17 (starting winning). In these jobs, various memories stored in the built-in RAM 481 of the main control unit 140 shown in FIG. 16 are used.

  First, as shown in FIG. 17, it is determined whether or not there has been a start prize (S200). As a result, if there is no start prize, the process skips to S250 and confirms whether there is a hold. As a result, when there is no hold (when the number of holds is zero), the process returns to S200, and when there is a hold (when the number of holds is 1 to 4), the process proceeds to S255.

  On the other hand, when there is a start winning, it is determined whether or not the number of pending (unstarted number) exceeds a certain value (“3” in the gaming machine 1) (S210). If the number of reserves (the number of unstarted times) exceeds a certain value, the start winning is invalid and skips to S255. On the other hand, if the number of holdings (the number of unstarted times) does not exceed a certain value, the number of holdings stored in the special symbol holding number memory 481b is increased by 1 (S220).

  Next, a special symbol success / failure determination random number (hereinafter also referred to as a success / failure random number or determination random number) is generated (randomness determination random number generation means) and read (S230). The validity random number generation means may use software or hardware. The read determination random number value is stored in a special symbol success / failure determination random number memory 481a (hereinafter also referred to as a determination random number memory) (S240). In this memory, the read determination random number value is stored in the shift memory format in the time series of the start winning prize.

  Next, the oldest first determination random number value stored in the determination random number memory 481a is read (S255), and the big hit number (winning determination value) is read from the big hit number memory 482a in the ROM 482 (S260). Then, it is determined whether or not the determined random number value matches the jackpot number (S265). As a result, if the two match, the big hit determination is made, and the big hit processing is performed (S270).

  Next, the big hit process (S270) will be described with reference to FIG. First, a jackpot symbol determination random number (identification information determination random number) is generated and read (S280). Then, it is determined whether or not the probability is changed based on the determination random number value read in S230. When it is determined that “probability is not changed” (S282: NO), the process proceeds to S284, and the probability that the special symbol becomes a specific symbol is set to a normal probability (low probability), and then the process proceeds to S300. On the other hand, when the probability is changed (S282: YES), the process proceeds to S286, the probability that the special symbol becomes a specific symbol is set to a high probability, and the process proceeds to S300. In S300, the determination result of “big hit” (“1” in the gaming machine 1) is stored in the determination result memory 481j (S300), and this process ends.

  An outline of the specific state determination processing executed by the CPU 401 based on the program stored in the ROM 482 (see FIG. 17) of the main control unit 140 is shown in the flowchart of FIG. This process is started when the big hit ends. When the big hit ends (S700: YES), a specific state transition determination random number is acquired and stored in the specific state transition determination random number memory 481r (see FIG. 13). In subsequent S720, it is determined whether or not the winning is based on the random number for determining the specific state transition. Here, winning refers to shifting the gaming machine 1 to a specific state. If it is off (S720: NO), this process ends. In the case of winning (S720: YES), the process proceeds to S730, where a table selection random number is acquired and stored in the table selection random number memory 481q. In subsequent S740, based on the table selection random number, it is determined whether to use the long time table or the short time table. Here, the long time table stores a plurality of types of variation patterns of special symbols, and the average variation time is longer than that of the short time table. An example of the long time table is shown in [Table 1], and an example of the short time table is shown in [Table 2].

  When it is determined that the table is a long time table (S740: YES), the process proceeds to S750, the long time table is acquired from the ROM 482, and the process proceeds to S770. When it is determined that the table is a short time table (S740: NO), the process proceeds to S760, the short time table is acquired from the ROM 482, and the process proceeds to S770. In S770, “0” is set in the determination result memory 481j, and this process ends. Since the specific state determination process is started after the big hit as described above, “1” is set in the determination result memory 481j before executing S770.

  When the game ball passes through the normal symbol operation gate 36, the specific state process shown in FIG. 22 is started. First, in S800, it is determined whether or not the determination result memory 481j is 1. If the determination result memory 481j is 1 (S800: YES), this process ends. If it is determined that the determination result memory 481j is not 1 (S800: NO), that is, 0, the process proceeds to S805, where a random number for determining whether or not a normal symbol is obtained is stored in a random number memory 481p for determining whether or not a normal symbol is appropriate. In subsequent S810, it is determined whether or not the normal symbol is a hit based on the normal symbol success / failure determination random number. In the case of winning (S810: YES), the process proceeds to S815, the normal symbol is changed in the region 73, stopped at the winning symbol in S820, the normal electric accessory 71 is opened for a predetermined time, and then closed (this diagram). In this case, it is written as “activate a normal electric role”) and the process is terminated. In the case of detachment (S810: NO), the process proceeds to S835, where the normal symbol determining random number is acquired and stored in the normal symbol determining random number memory 481s. In step S840, the normal symbol is changed in the region 73, and in step S845, the normal symbol is stopped at the set symbol (the out symbol determined by the normal symbol determination random number acquired in step S835), and the process is terminated.

  Note that the same processing as S805 to S845 is performed even in a state that is not in a specific state (when YES is determined in S800; referred to as a non-specific state), but in the non-specific state, the ordinary electric accessory 71 opens only 0.3 seconds. Absent. Moreover, since the variation time of the normal symbol is as long as about 1 minute, it is inefficient to hit as shown by the arrow B in anticipation of winning the normal electric accessory 71. On the other hand, in the specific state, when the normal symbol is hit, the ordinary electric accessory 71 is opened for several seconds, and the fluctuation time of the normal symbol is also shorter than that in the non-specific state, so that a large amount of balls can be obtained. .

  As described above, in the gaming machine 1 described above, the game is performed as follows. In other words, after the game machine 1 is turned on, in a state where no special symbol is hit, the player drives the game ball into the game area 11 so that the game ball flows as shown by an arrow A in FIG. This is because more special symbols can be variably displayed with less investment by aiming at the first start port 17a. Even if a prize is awarded to the second starting port 17b, the special symbol changes. However, as described above, the second starting port 17b is more difficult to win than the first starting port 17a, so the first starting port 17a is aimed. Is wise. Note that if there is a course that allows the first start port 17a to win more efficiently than the arrow A, the player may play other than the arrow A.

  When the special symbol is hit, the special winning opening 311 is opened a predetermined number of times, and the big hit is completed, a lottery is performed as to whether or not to shift to a specific state (S720). When the player is out of the lottery of S720, the player hits the game ball again aiming at the first starting port 17a as shown by the arrow A. On the other hand, when the lottery is won and the state is shifted to a specific state, the game ball is driven into the game area 11 so that the game ball flows as indicated by an arrow B in FIG. This is because the normal symbol is changed by aiming at the normal symbol operation gate 36, and the normal electric accessory 71 is opened by applying the normal symbol.

  The specific state ends when a special symbol is hit. That is, if the player is hitting a game ball as shown by the arrow B, the player sometimes wins the second starting port 17b although it is difficult to win from the first starting port 17a. When the special symbol fluctuates and the jackpot is reached, the determination result memory 481j becomes “1” (S300), and the processing of S805 to S845 is not performed. That is, it is not in a specific state. Since a special symbol is likely to hit in the probability variation state, the specific state is more likely to end in the probability variation state than in the non-probability variation state.

  In addition, before entering a specific state, a long table with a long special symbol variation time or a short table with a short special symbol variation time will be drawn. It takes time for the special symbol to be stopped and displayed even in the middle, and this increases the specific state.

  It should be noted that in the probability variation state where the special symbol has a high probability, a big hit occurs with the special symbol becoming a specific symbol early on. Therefore, if the probability of the special symbol is changed and the player is in a specific state, the player will be informed that the special symbol has been won (stock display) even though the special symbol has not been won. You may give to. In this case, it will display that the stock will be released when the special symbol is actually won. Alternatively, select a long variation time (5 minutes) with a special symbol, display that it was won immediately before the change (stock display), display that the stock will be released after the end of the change, and show the player the stock period It is also possible to produce an illusion as if there was.

As described above, according to the gaming machine 1 described above, since the specific state occurs after the completion of the special symbol hit, it is possible to provide a gaming machine having many elements advantageous to the player.
In addition, since the second start port 17b is present on the same right side as the normal symbol operating gate 36 in the game area 11, the game is played while enjoying the thrill that "the specific state may end". There will be something. Further, since the specific state is terminated by hitting the special symbol, it is very effective as a remedy for the player who has not been in the probability variation state.

  Moreover, in a specific state, it is possible to lengthen the variation time of the special symbol by assigning a table for a long time by lottery, and in that case, it is more advantageous than the case of drawing a short time table (the variation time of the special symbol) The longer it takes for the special symbol to hit, the longer it will take.). As a result, the gaming machine 1 is a model having an unprecedented gaming interest such as which table to be assigned for a long time or a short time.
