  According to the present invention, it is possible to improve the interest by associating the occurrence of the big hit gaming state with the change in the image display of the display means.

Hereinafter, an embodiment in which the present invention is embodied in one type of pachinko gaming machine (hereinafter referred to as “pachinko machine”) will be described with reference to FIGS.
In FIG. 1, the front side of the pachinko machine 10 is schematically shown, and a vertical rectangular middle frame 12 for setting various game components is opened and closed on the front side of the opening of the outer frame 11 that forms the outline of the machine body. And is detachably assembled. Further, on the front side of the middle frame 12, a front frame 14 and a top ball tray 15 each having a glass frame for protecting the game board 13 disposed inside the machine in a see-through manner are assembled so as to be openable and closable in a laterally open state. ing. The front side of the front frame 14 and the game board 13 are turned on (flashing) or turned off according to various game states of the pachinko machine 10 (symbol fluctuation, big hit state, reach state, etc.), and light emission based on light emitting decoration An electric lamp 16 that performs an effect is arranged. The upper ball tray 15 is provided with a speaker 17 that outputs various sounds according to the state of the various games and performs sound effects based on the sound output. A launcher 19 is attached.

  In addition, a symbol display device 20 as a display means provided with a visible display portion H made of a liquid crystal screen is disposed in the approximate center of the game area 13 a of the game board 13. In the visible display portion H, a display effect based on a varying image (or image display) is performed. In the visible display portion H, a symbol combination game is displayed in which a plurality of types of symbols Z are changed (variable) and displayed in association with the display effect. “Display the symbol Z” means that the symbol Z stops in a state where the player can identify the type of the symbol Z in the visible display portion H. The “stop” includes both a so-called “swing fluctuation” once stopped state and a completely stopped stop state.

  In the visible display portion H of the symbol display device 20, a plurality of columns (three columns in this embodiment) of symbols Z are displayed for each column as shown in FIG. A background image B is displayed. Then, the player can recognize any one of the big hit state, the reach state, and the disengaged state according to the symbol combination including the three rows of symbols Z displayed on the visible display portion H. For example, when the symbols Z of all the columns displayed on the visible display portion H are of the same type, the big hit state can be recognized from the symbol combination ([777] or the like). Further, when the symbols Z of the specific columns (for example, the left column and the right column as viewed from the player side) displayed on the visible display portion H are of the same type, the symbol combination ([7 ↓ 7], etc.) “↓” indicates that the pattern Z is changing), and the reach state can be recognized. Further, when all the symbols Z displayed in the visible display portion H are not of the same type, a state of deviation from the symbol combination ([259] [887] [787], etc.) can be recognized.

  In the pachinko machine 10, various game effects are performed in order to enhance the interest of the game. For example, in the visible display part H, when a symbol combination that can recognize the reach state is displayed, the remaining one row of symbols Z is changed slowly or quickly. In addition, a character other than the symbol Z appears, and the symbol Z is displayed corresponding to the movement of the character, or the background of the visible display portion H is changed in various patterns. Further, along with the progress of the symbol combination game performed in the visible display portion H, the decoration lamp 16 is decorated with various patterns, and various sounds (sound effects) are output from the speaker 17.

  In particular, the normal background to be displayed on the visual display unit H during normal variation of the symbol combination game and when the symbol combination game is not being executed is the player who has the highest number of images displayed in the display effect. It is an image I often see. The “normal fluctuation” is a symbol fluctuation state from the start of the fluctuation of the symbol Z until a predetermined symbol combination is formed. Specifically, in a symbol combination game performed in the visible display portion H, a symbol variation state from the start of symbol variation until a reach state symbol combination is formed, or a combination that can recognize a symbol that is out of reach without reaching a reach state. It is a pattern fluctuation state until is formed. In this embodiment, there are two types of normal backgrounds displayed on the visible display portion H, the normal background 1 is an “mountain road” image, and the normal background 2 is an “street road” image. In addition, the symbol combination game is started, and in the visible display portion H, the symbol variation starts on the normal background image. After the symbol Z forms the reach state in the visible display portion H, the reach is displayed in the visible display portion H. The reach effect is displayed as a background image (reach display) different from the normal background according to the state. Then, in the visible display portion H, a middle symbol of the same type as the symbol forming the reach state is derived, and when the symbol combination that can recognize the big hit state is confirmed and stopped, the big hit gaming state is given.

  In addition, a start winning opening 22 including an opening / closing blade 21 that is opened and closed by a solenoid (not shown) is disposed below the symbol display device 20. The start winning opening 22 can give a start condition (= start condition) of a symbol combination game in the symbol display device 20 when a winning of a game ball launched into the game area 13a is detected. Also, below the start winning opening 22, a large winning opening 23 that is opened and closed by a solenoid (not shown) is disposed. The big winning opening 23 opens and closes when the symbol combination derived by the symbol combination game becomes a symbol combination that can recognize the big hit state. The chance to win a large number of game balls is given to the player by the opening operation of the special winning opening 23.

  When the jackpot game state is given, the pachinko machine 10 shifts to the jackpot game, and in the jackpot game, the big prize opening 23 has a predetermined number of rounds (this embodiment) determined in advance by the establishment of a predetermined continuation condition. In this case, opening and closing are repeated up to 15 rounds). When the big hit gaming state is given, an opening effect is performed first, and after the opening effect is finished, a game of each round is performed. Then, when the game of the last round is finished, an ending effect is performed, and the big hit gaming state is finished by the end of the ending effect. Then, if there is a symbol combination game held during the big hit gaming state, the symbol combination game is started. During the jackpot game, the visual display portion H displays the opening effect, the round effect in each round, and the ending effect as images. Hereinafter, when these effects are described together, they are indicated as “hit game display”. . Further, during the big hit gaming state, the symbol combination game is not performed, and the normal background is not displayed on the visible display portion H.

  As shown in FIG. 3, a plurality of such pachinko machines 10 are arranged in parallel on an installation frame base 24 also called “island” installed in a game arcade. A gaming system is configured by a plurality of pachinko machines 10 installed on the installation frame base 24. The installation frame base 24 is formed with a plurality of vertical rectangular installation frames 25 formed by surrounding four sides with a planar installation surface (not shown). The outer frame 11 of the pachinko machine 10 is installed and fixed to the installation frame 25. In addition, the installation frame base 24 is provided with a power supply device for turning on power to a plurality of pachinko machines 10 installed on the installation frame base 24 at the same time. Note that the power supply device may be provided outside the installation frame 24.

Next, the control configuration of the pachinko machine 10 will be described in detail with reference to FIG.
On the back side of the pachinko machine 10, a main control board 26 as main control means is mounted as shown in FIG. The main control board 26 executes various processes for controlling the entire game in the pachinko machine 10 and performs arithmetic processing on various control commands in accordance with the processing results. It is designed to output as a signal. The main control board 26 includes a display control board 27 for controlling the display effect mode of the symbol display device 20, a lamp control board 28 for controlling the light emission effect mode of the electric lamp 16, and a sound effect mode of the speaker 17. A sound control board 29 for controlling the sound is connected. In the present embodiment, the display control board 27, the lamp control board 28, and the sound control board 29 have their respective control targets determined as described above, and the main control target is controlled professionally. With respect to the main control board 26 which is a control means, it is comprised so that it may function as a sub-control means (enclosed with the dashed-dotted line in FIG. 4).

  The main control board 26 includes a main CPU 26a that functions as a big hit determination means, and a ROM 26b and a RAM 26c are connected to the main CPU 26a. The main CPU 26a is a jackpot determination random number (0 to 946), a fluctuation pattern distribution random number (0 to 9), a jackpot symbol random number (0 to 9), a left symbol random number (0 to 9), a right offset The values of various random numbers such as the random number for symbols (0-9), the random number for random symbols (0-9), and the random number for reach determination (0-49) are sequentially updated at predetermined intervals. The main CPU 26a sets the updated value in the RAM 26c and overwrites the value before the update. The ROM 26b stores a control program for controlling the pachinko machine 10 and a plurality of types of variation patterns related to symbol variation. The RAM 26c stores various information (such as various random values) that can be rewritten as appropriate during the operation of the pachinko machine 10. Then, the main CPU 26a is triggered by the detection of the winning of the game ball to the start winning opening 22 at the start of the symbol combination game, such as jackpot determination, determination and output of the stop symbol designation command, determination and output of the variation pattern designation command, etc. Processing is to be executed. The “stop symbol designation command” is a command for designating a symbol Z to be confirmed and stopped in the symbol combination game, and the “variation pattern designation command” is for instructing the symbol variation start and the variation pattern (described later). This is a command to specify.

  Further, when the big hit gaming state is generated, the main CPU 26a first outputs an opening designation command instructing the start of the opening effect. Next, the main CPU 26a sequentially outputs round designation commands instructing the start of each round effect at the timing when the game of each round starts. Thereafter, the main CPU 26a outputs an ending designation command instructing the start of the ending effect at the end of the final round.

  The “big hit determination random number” means whether or not the main CPU 26a acquires a random number in response to the detection of a winning of a game ball in the start winning opening 22, and whether or not it is a big hit at the start of a game effect (symbol combination game). This is a random number for comparison with the jackpot judgment value in the jackpot judgment for judging (determining). The “variation pattern distribution random number” is determined by the main CPU 26a using which variation pattern among the plurality of types of variation patterns stored in the ROM 26b to perform a game effect (design variation, symbol combination game). It is a random number to do. The “hit symbol random number” is a random number for determining the big hit symbol (stop symbol) that the main CPU 26a finally stops in the visible display portion H when the big hit is determined.

  Further, the “missing left symbol random number” is a random number for determining a missing symbol (stop symbol) that the main CPU 26a finally stops in the visual display unit H when the big hit determination result is negative. Similarly, the “offset right symbol random number” is a random number for determining the offright symbol (stop symbol) that the main CPU 26a finally stops in the visible display unit H when the big hit determination result is negative. Similarly, the “random symbol for out-of-line symbol” is a random number for determining the out-of-line symbol (stop symbol) that the main CPU 26a finally stops in the visible display unit H when the big hit determination result is negative. The “reach determination random number” is used to determine whether or not the main CPU 26a performs a reach in the visible display portion H (whether or not to perform a missed reach) when the result of the big hit determination is negative. It is a random number.

  Further, the “variation pattern” indicates a pattern that is a base (basic or basic) of the game performance performed by the pachinko machine 10, and at least the time of the game performance (the variation start of the symbol Z performed in the symbol combination game) To the time when the symbol Z is fixed and stopped). The “variation pattern” includes “fluctuation pattern for loss”, “variation pattern for loss reach”, and “variation pattern for big hit”. It should be noted that the “fluctuation pattern for deviation” can specify that the left ≠ right symbol combination, and the “fluctuation pattern for detachment reach” has the symbol combination of left = right ≠ middle. It can be specified. Further, the “big hit variation pattern” can specify that the symbols Z of all the columns in the middle left and right are of the same type (left = middle = right).

Next, the display control board 27 will be described.
The display control board 27 includes a sub CPU 27a that functions as background image data determination means, and a ROM 27b and a RAM 27c that function as background image data storage means are connected to the sub CPU 27a. The sub CPU 27a sequentially updates values of various random numbers such as normal background change random numbers (0 to 9) and change timing random numbers (0 to 18) at predetermined intervals, sets the updated values in the RAM 27c, and updates them. The previous value is overwritten. The ROM 27b stores a display control program for controlling display contents of the symbol display device 20 (visible display portion H). The display control program includes display effect data for the sub CPU 27a to control the symbol display device 20 (visible display unit H) so that a display effect based on the variation pattern designation command output from the main CPU 26a is performed. It is.

  The ROM 27b stores various image data (design image data, background image data, character image data, appearance character image data, and the like). In the present embodiment, the background image data D1 corresponding to the normal background 1 (mountain road) and the background image data D2 corresponding to the normal background 2 (street) are displayed as the background image data related to the normal background displayed on the visible display unit H. Are stored in the ROM 27b. The RAM 27c stores (sets) various data (such as the various random numbers) that can be appropriately rewritten during the operation of the pachinko machine 10. The “normal background change random number” is a random number for the sub CPU 27a to determine whether or not to change the normal background displayed on the visible display unit H in the symbol combination game that is a big hit. The “change timing random number” is a random number for the sub CPU 27a to determine the timing for changing the normal background displayed on the visible display unit H in the symbol combination game that is a big hit.

  The pachinko machine 10 according to the present embodiment is configured to change the normal background displayed on the visible display unit H at predetermined intervals (every 10 minutes in the present embodiment) determined with reference to power-on. ing. Furthermore, when the symbol combination game based on the big hit variation pattern is performed during one cycle, the pachinko machine 10 of the present embodiment uses another type of normal background displayed at the start of the cycle at a predetermined timing. It is configured to change to the background. A jackpot notice that informs the player in advance that a jackpot gaming state may occur in a symbol combination game involving the change by changing the normal background displayed at the start of the cycle to another type of regular background. (Notice production).

  Hereinafter, in the pachinko machine 10 of the present embodiment configured as described above, a normal background determination processing routine performed by the sub CPU 27a of the display control board 27 based on the display control program will be described with reference to FIGS.

  First, in step S1, the sub CPU 27a outputs a power-on initial designation command output from the main control board 26 when the pachinko machine 10 is turned on, or a power output output from the main control board 26 when power is restored after a power failure or the like. Enter the command to specify when power is restored. Then, the sub CPU 27a starts measuring the time T by a timer (not shown) provided in the sub CPU 27a based on the input of the power-on initial designation command or the power-on / return-time designation command. The timer counts time independently until the power supply is cut off when the power is turned off or a power failure occurs. In step S2, the sub CPU 27a determines the background image data D1 corresponding to the normal background 1, which is the initial setting, from the ROM 27b, and sets “1” as the value of the type flag indicating the background image data D1. The data is stored in the address α which is a storage area of the RAM 27c. In the present embodiment, the value of the type flag indicating the background image data D1 is “1”, and the value of the type flag indicating the background image data D2 is “2”. In the present embodiment, the address α of the storage area of the RAM 27c is a storage area for storing the value of the type flag indicating the type of background image data of the normal background that is periodically changed.

  Then, the process goes to step S3, and the sub CPU 27a acquires the time T of the timer currently measured (that is, at the time of initial setting of the normal background 1) and stores it in the RAM 27c as the time A. Subsequently, the process proceeds to step S4, and the sub CPU 27a determines whether or not a variation pattern designation command output from the main control board 26 is input.

  If the determination result in step S4 is affirmative, the process proceeds to step S5. In step S5, the sub CPU 27a determines whether or not the variation pattern designation command input in step S4 is a big hit variation pattern. If the determination result in step S5 is negative, the process proceeds to step S6. In step S6, the sub CPU 27a acquires the time T of the timer and reads the time A stored in the RAM 27c. Then, it is determined whether or not time T ≧ time A + predetermined time N (in this embodiment, the predetermined time N is 10 minutes (min)). If the determination result in step S6 is negative, that is, it is less than 10 minutes, which is the normal background change period, the process proceeds to step S7. In step S7, the sub CPU 27a determines to maintain the normal background display based on the background image data corresponding to the value of the type flag set in the address α. Then, the sub CPU 27a returns to step S4.

  On the other hand, if the determination result in step S6 is affirmative, that is, that 10 minutes, which is the normal background change period, has elapsed, the process proceeds to step S8. In step S8, the sub CPU 27a displays the background image data different from the background image data (background image data determined in the immediately preceding cycle) corresponding to the value of the type flag stored in the address α of the RAM 27c after the change. To be determined as background image data of the normal background. For example, when the value of the type flag stored in the address α of the RAM 27c is “1” in step S8, the sub CPU 27a determines that the background image data D2 is different from the background image data D1 corresponding to the value 1 of the type flag. To decide. If the value of the type flag stored at the address α of the RAM 27c is “2” in step S8, the sub CPU 27a determines that the background image data D1 is different from the background image data D2 corresponding to the value 2 of the type flag. To decide. In step S9, the sub CPU 27a newly stores (overwrites) the value of the type flag indicating the type of background image data (normal background) determined in step S8 in the address α of the RAM 27c, and returns to step S3. . In step S3, the sub CPU 27a acquires the time T of the currently measured timer and newly stores (overwrites) it as the time A in the RAM 27c. Thereafter, the process proceeds to step S4.

  If the determination result in step S5 is affirmative, that is, that a big hit variation pattern has been input, the process proceeds to step S10 (FIG. 6). In step S10, the sub CPU 27a acquires the time T of the timer and reads the time A stored in the RAM 27c. Then, the sub CPU 27a determines whether or not the time T is within the range of the notice period (specific period) (time A + predetermined time X ≦ time T ≦ time A + predetermined time Y). (In this embodiment, the predetermined time X is 2 minutes and the predetermined time Y is 7 minutes). The notice period is a period in which a big hit notice can be made by changing the normal background during one cycle (10 minutes).

  If the determination result in step S10 is affirmative, that is, it is within the range of the notice period, the process proceeds to step S11. If the determination result in step S10 is negative, the process proceeds to step S4 (FIG. 5). In step S11, the sub CPU 27a extracts the value of the normal background change random number (0 to 9) and performs a lottery to determine whether or not the normal background can be changed. Subsequently, in step S12, the sub CPU 27a determines whether or not to change the normal background based on the lottery result indicating whether or not the normal background can be changed in step S11. In this embodiment, when the value of the extracted normal background change random number is 0, the determination result of step S11 is affirmed. Whether or not to make a big hit notice by changing the normal background is determined by the processing of steps S11 and S12. If the determination result in step S12 is negative, that is, the normal background is not changed (the jackpot notice is not executed), and the process proceeds to step S4 (FIG. 5).

  On the other hand, if the determination result in step S12 is affirmative, that is, the normal background is changed (a big hit notice is executed), and the process proceeds to step S13. In step S13, the sub CPU 27a sets a change flag in the RAM 27c. The change flag is a flag for instructing to change the normal background in order to make a jackpot notice. Accordingly, when the change flag is set, in the background output processing routine (FIG. 8), instead of the normal background based on the background image data corresponding to the value of the type flag stored in the address α of the RAM 27c, A normal background based on the background image data corresponding to the value of the type flag stored at the address β is displayed on the visible display portion H. In the present embodiment, the address β of the storage area of the RAM 27c is a storage area for storing the value of the type flag indicating the background image data corresponding to the normal background for jackpot notification.

  Subsequently, the process proceeds to step S14, and the sub CPU 27a determines the type of normal background to be changed. That is, the sub CPU 27a newly determines background image data different from the background image data (background image data determined at the start of the cycle) corresponding to the value of the type flag stored in the address α of the RAM 27c. For example, when the type flag indicating the background image data D1 is set at the address α, the sub CPU 27a determines the background image data D2 in step S14. In step S15, the sub CPU 27a newly stores (overwrites) the value of the type flag indicating the background image data determined in step S14 in the address β of the RAM 27c. In the present embodiment, even if a new type flag value is stored at the address β of the RAM 27c, the type flag value stored at the address α of the RAM 27c is maintained.

  In step S16, the sub CPU 27a determines the timing for changing the normal background in the symbol combination game based on the input jackpot variation pattern. That is, the sub CPU 27a determines at which timing the normal background is changed during the normal variation of the symbol combination game. In this embodiment, in the symbol combination game based on the big hit variation pattern, the normal variation (from the variation start to the reach state formation) is set to 18 seconds, and the normal background is changed after how many seconds from the variation start. Decide what to do. Specifically, the sub CPU 27a extracts the value of the change timing random number (0 to 18) from the RAM 27c, and determines the timing associated with the extracted change timing random number in advance. For example, the change timing random number value “0” is “changed simultaneously with the start of symbol variation”, the change timing random number value “1” is “changed one second after the start of symbol variation”,. The value “18” is associated with “change after 18 seconds from the start of symbol variation”. Then, the process proceeds to step S17, and the sub CPU 27a sets the data related to the normal background change timing determined in step S16 in the RAM 27c, and then proceeds to step S4 (FIG. 5). In the present embodiment, the sub CPU 27a functions as a display timing determination unit in the processes of step S16 and step S17.

  On the other hand, if the determination result in step S4 is negative, the process proceeds to step S18 (FIG. 7). In step S18, the sub CPU 27a determines whether or not an opening designation command output from the main control board 26 has been input. If the determination result in step S18 is affirmative, the process proceeds to step S19. Subsequently, in step S19, the sub CPU 27a checks the RAM 27c and determines whether or not the change flag is set. If the determination result in step S19 is affirmative, that is, the change flag is set, the process proceeds to step S20. In step S20, the sub CPU 27a clears (cancels) the change flag set in the RAM 27c because the big hit gaming state has occurred. That is, since the change flag is cleared in step S20, when the output process of the background image data corresponding to the normal background is performed in the background output process routine (FIG. 8), the sub CPU 27a is stored at the address α. The background image data indicated by the type flag value is read from the ROM 27b and output (displayed). Moreover, when the determination result in step S18 or step S19 is a negative determination, the process proceeds to step S6 (FIG. 5).

Next, a background output processing routine performed by the sub CPU 27a of the display control board 27 based on the display control program will be described with reference to FIG.
First, in step S31, the sub CPU 27a determines whether or not to output normal background background image data. If the determination result in step S31 is affirmative, that is, normal background image data is output, and the process proceeds to step S32. In step S32, the sub CPU 27a checks the change flag stored in the RAM 27c and determines whether or not the change flag is set. If the determination result in step S32 is affirmative, that is, the change flag is not set, the process proceeds to step S33. In step S33, the sub CPU 27a confirms the value of the type flag stored in the address α of the RAM 27c, reads the background image data indicated by the value of the type flag from the ROM 27b, and outputs it to the symbol display device 20. . As a result of this processing, a normal background that is periodically changed is displayed on the visible display portion H.

  On the other hand, if the determination result in step S32 is negative, that is, the change flag is set, the process proceeds to step S34. Then, in step S34, the sub CPU 27a changes the normal background and makes a big hit announcement, so the value of the type flag stored in the address β of the RAM 27c is confirmed, and the background image indicated by the value of the type flag is displayed. Data is read from the ROM 27 b and output to the symbol display device 20. At this time, the sub CPU 27a outputs background image data according to the change timing of the normal background stored in the RAM 27c. By this processing, the normal background is changed in the visible display portion H before reaching one cycle (10 minutes), and the normal background as a big hit notice is displayed.

  If the determination result in step S31 is negative, that is, background image data other than the normal background is output, and the process proceeds to step S35. In step S35, the sub CPU 27a selects a background other than the normal background specified by various commands such as a variation pattern designation command and an opening designation command input from the main CPU 26a (for example, a background during reach display, a jackpot game display). The background image data corresponding to the background of the time is read from the ROM 27 b and output to the symbol display device 20. By this processing, the background display other than the normal background is performed in the visible display portion H.

  Hereinafter, in the pachinko machine 10 of the present embodiment configured as described above, an aspect in which a display effect is performed will be described based on the example illustrated in FIGS. 9 and 10. 9 and 10, the background display mode indicates a background image displayed on the visible display unit H of the symbol display device 20, and normal background determination processing (FIG. 5 to FIG. FIG. 7) shows a normal background corresponding to the background image data determined by the sub CPU 27a.

  First, FIG. 9A will be described. When power is turned on to the pachinko machine 10, the sub CPU 27a of the display control board 27 sets the type flag indicating the background image data D1 corresponding to the normal background 1 to the address α of the RAM 27c. Further, the sub CPU 27a reads the background image data D1 from the ROM 27b and outputs it to the symbol display device 20. As a result, the normal background 1 is displayed as an image on the visible display portion H.

  When the main CPU 26a determines a big hit when the time G1 (3 minutes (min)) elapses after the power is turned on, the sub CPU 27a inputs a fluctuation pattern designation command for designating a big hit fluctuation pattern. The sub CPU 27a that has input the change pattern designation command acquires the time T of the timer at that time. In this example, the acquired time T is within the notice period shown in step S10 of the normal background determination process (FIG. 6), so the sub CPU 27a determines whether or not to make a big hit notice by changing the background (FIG. 6 steps S11, S12). When the determination result is affirmative, the sub CPU 27a newly determines background image data (step S14 in FIG. 6), and stores the value of the type flag at the address β in the RAM 27c (step S15 in FIG. 6). In this example, since the type flag indicating the background image data D1 is set at the address α, the sub CPU 27a determines the type flag indicating the background image data D2 as the type flag stored at the address β. In this example, the sub CPU 27a determines that the normal background is changed simultaneously with the value “0” of the change timing random number, that is, the symbol combination game, in step S16 of the normal background determination process (FIG. 6). To do.

  Then, at the time G1, the symbol combination game starts on the visible display portion H (design variation start). In addition, at the time when the symbol combination game is started (at the start of normal variation), the normal background displayed on the visible display portion H is determined at step S16 in the normal background determination process (FIG. 6). The normal background 1 corresponding to the type flag “1” stored at the address α is changed to the normal background 2 based on the type flag “2” stored at the address β. The change of the normal background causes a jackpot notice, and the player recognizes that the jackpot notice has been made because the normal background has been changed at an earlier stage than the timing at which the background is periodically changed. Increase the expectation of At time R1, a reach state is formed in the visible display portion H, and a reach display is performed instead of the normal background 2. Thereafter, a symbol combination that can recognize the big hit state is derived in the visible display portion H, and when the big hit is determined at the time K1, the big hit game display is performed.

  When the jackpot game display is performed, the sub CPU 27a first inputs an opening designation command, and thus clears the change flag set when the jackpot notice is determined. Therefore, the sub CPU 27a determines the normal background 1 as the normal background. When the big hit game display ends, the sub CPU 27a displays the normal background on the visible display unit H as an image. At this time, since the change flag is cleared, the sub CPU 27a reads the background image data D1 corresponding to the value of the type flag stored at the address α from the ROM 27b and outputs it to the symbol display device 20. As a result, in the visible display portion H, the normal background 1 that has been displayed at the start of the cycle is displayed again.

  Thereafter, when 10 minutes have elapsed since the power was turned on, the sub CPU 27a periodically changes the normal background, so that the background image data is newly determined (step S8 in FIG. 5), and the type flag is set at the address α of the RAM 27c. Is stored (step S9 in FIG. 5). In this example, the sub CPU 27a determines the background image data D2 because the type flag indicating the background image data D1 is set at the address α. Then, the sub CPU 27a reads the background image data D2 corresponding to the value of the type flag stored at the address α from the ROM 27b and outputs it to the symbol display device 20. As a result, in the visible display portion H, the normal background 2 is displayed as an image instead of the normal background 1 by a periodic change after 10 minutes have elapsed since the power was turned on.

  Next, FIG. 10 will be described. This example shows an aspect of display effects when the big hit gaming state spans two cycles. The description overlapping with the description of FIG. 9A is omitted or simplified.

  When the main CPU 26a determines the big hit, at time G2, when the symbol combination game starts (at the start of normal fluctuation), the normal background displayed in the image on the visible display portion H is changed to give a big hit notice. The FIG. 10 shows a state in which the normal background is changed from the normal background 1 to the normal background 2. At time R2, a reach state is formed in the visible display portion H, and a reach display is performed instead of the normal background 2. Thereafter, a symbol combination that can recognize the big hit state is derived in the visible display portion H, and when the big hit is determined at time K2, the big hit game display is performed. Further, the sub CPU 27a clears the change flag in response to the input of an opening designation command. Therefore, the RAM 27c determines the normal background 1 as the normal background. In the example shown in FIG. 10, the jackpot game display is performed when 8 minutes (min) have elapsed after the start of the cycle, and the jackpot game display is performed over the next cycle.

  Then, when 10 minutes have elapsed since the start of the cycle, the sub CPU 27a periodically changes the background, so that the background image data is newly determined (step S8 in FIG. 5), and the type of the address α in the RAM 27c is The flag value is stored (step S9 in FIG. 5). In this example, the sub CPU 27a determines the background image data D2 because the type flag indicating the background image data D1 is set at the address α. Then, when the big hit game display ends, the sub CPU 27a reads the background image data D2 corresponding to the value of the type flag stored in the address α from the ROM 27b and outputs it to the symbol display device 20. As a result, in the visible display portion H, the normal background 2 is displayed as an image instead of the normal background 1 by periodic change.

  As described above, in this embodiment, when the time T measured by the sub CPU 27a has passed the predetermined time 10 minutes from the time A set in the RAM 27c (time T ≧ time A + 10 minutes), the normal background is changed. Is done. That is, due to periodic changes, the normal background displayed on the visible display portion H changes according to a predetermined order (normal background different from the previous normal image display) (normal background 1 → normal background). 2 → normal background 1 → normal background 2 → normal background 1 →.

  Further, in this embodiment, when the symbol combination game start time T is within the range of the notice period and a symbol combination game that is a big hit is performed, the normal background changes as a big hit notice. Specifically, during normal fluctuation of the symbol combination game that is a big hit, it changes to a normal background different from the normal background that was displayed before the symbol combination game was played (normal background 1 → normal background 2 or normal Background 2 → Normal background 1).

Next, the manner in which the display effect is performed in the gaming system will be described based on the example shown in FIGS.
FIG. 9B shows a display mode of a normal background when a game is not performed by the player and a so-called customer waiting state continues. Since the plurality of pachinko machines 10 constituting the gaming system are turned on almost simultaneously, the pachinko machine 10 shown in FIG. 9A and the pachinko machine 10 shown in FIG. The normal background 1 is displayed as an image in the part H. Then, when the symbol combination game that is a big hit with the pachinko machine 10 shown in FIG. 9A starts at the time G1, the normal background displayed as an image on the visible display portion H is changed from the normal background 1 to the normal background 1 during normal fluctuation. Changed to background 2. On the other hand, in the pachinko machine 10 shown in FIG. 9B, the normal background displayed as an image on the visible display portion H remains the normal background 1. Accordingly, when a player who is playing with the pachinko machine 10 in FIG. 9A sees the pachinko machine 10 in FIG. 9B, the normal background has changed from the normal background 1 to the normal background 2. It can be assumed that this is not a big change but a big hit notice.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) When the main CPU 26a determines a big hit and a symbol combination game based on the determination result is executed, the sub CPU 27a newly determines background image data and determines it at the start of a predetermined period (10 minutes). The normal background displayed on the visible display portion H is changed based on the background image data. Therefore, it is possible to correlate the big hit with the change of the normal background displayed on the visible display portion H, and the function as a big hit notice is added to the change of the normal background displayed on the visible display portion H. be able to. Therefore, the player can be interested in the change of the normal background displayed on the visible display portion H, and the interest can be improved. Moreover, since the normal background displayed on the visible display part H is changed every predetermined period (10 minutes), when the normal background is changed, it is determined whether the change is a periodic change or a change based on jackpot. It can be assumed. As a result, every time the normal background displayed on the visible display portion H is changed, the player can have a sense of expectation for the big hit, and the interest can be improved.

  (2) Since the predetermined period (10 minutes) in which the normal background displayed on the visible display portion H changes is based on the time when the power is turned on, the periodicity when determining the background image data as the game progresses The background image data can always be determined based on a certain period without being changed. Therefore, it is possible to inform the player in an easy-to-understand manner whether or not the change of the normal background displayed on the visible display portion H is related to the jackpot notice.

  (3) When the main CPU 26a determines a big hit within a specific period (time A + 2 minutes ≦ time T ≦ time A + 7 minutes) and a symbol combination game based on the determination result is executed, the display is displayed on the visible display portion H. The normal background is changed. Therefore, in all cases where the main CPU 26a determines the big hit, the normal background displayed on the visible display portion H is not changed, and the case where the big hit gaming state occurs with the change of the normal background and the normal A case where a big hit gaming state is generated without changing the background can be created. Therefore, it can be made more interested to change the normal background displayed on the visible display portion H.

  (4) The sub CPU 27a is configured to determine the background image data in a predetermined order (predetermined order) (in this embodiment, background image data D1 → background image data D2 → background image data D1 → background image data). D2 →). Therefore, by providing regularity in the order in which the normal background displayed on the visible display portion H is changed, it is possible to make the player easily assume what normal background is changed. Therefore, when the normal background displayed on the visible display portion H is changed, it is possible to assume what kind of normal background will cause the big hit gaming state to occur.

  (5) When the normal background displayed on the visible display portion H is changed due to the determination of the big hit by the main CPU 26a, the main background is returned to the normal background before the change after the big hit game ends. Therefore, it is possible for the player to easily recognize that the big hit notice has been made by changing the normal background displayed on the visible display portion H. Therefore, the player recognizes that the normal background displayed on the visible display portion H is not merely made to ensure the freshness of the appearance, but also functions as a big hit notice. Can be made. Therefore, every time the normal background displayed on the visible display portion H is changed, the player can have a sense of expectation for the big hit, and the interest can be improved.

  (6) When the opening designation command is input, the sub CPU 27a clears the change flag of the RAM 27c, and therefore controls the normal background display based on the background image data set in the address α of the RAM 27c after the big hit game ends. Can do. Therefore, the process of returning the normal background displayed on the visible display portion H can be reliably executed. When the big hit game is over the next normal background change cycle, the sub CPU 27a clears the change flag in the RAM 27c when the opening designation command is input, and when the next cycle starts, what is the previous cycle? Different background image data is set to the address α of the RAM 27c. Therefore, even when the big hit game straddles the next normal background change cycle, the normal background based on the background image data that is surely different every predetermined cycle can be displayed on the visible display portion H.

  (7) The sub CPU 27a determines the timing for changing the normal background at the time of normal fluctuation in the symbol combination game based on the value of the change timing random number stored in the ROM 27b. Therefore, when the big hit is determined by the main CPU 26a, it is possible to give randomness to the timing at which the normal background displayed on the visible display portion H is changed. As a result, when the normal background displayed on the visible display portion H is changed, it is possible to make it difficult for the player to assume a periodic change or a change based on jackpot. Therefore, it is possible to give more interest to the timing when the normal background displayed on the visible display portion H is changed, and it is possible to further enhance the interest.

  (8) In the amusement store, a plurality of pachinko machines 10 of the same model are installed adjacent to the same installation frame base 24 (installation island), and the power is turned on all at once before the opening of the amusement store. Therefore, in the plurality of pachinko machines 10, the timing (cycle) at which the normal background displayed on the visible display unit H is changed coincides. Therefore, by comparing the normal background displayed on the visible display unit H of the other pachinko machine 10 with the normal background displayed on the visible display unit H of the pachinko machine 10 that the player is playing, the normal background is When changed, the player can easily assume whether it is a periodic change or a jackpot change. In addition, even a player who does not recognize that the change of the normal background displayed on the visible display portion H functions as a jackpot notice, only his / her pachinko machine 10 is different from other pachinko machines 10 When it is in the background, it can give a sense of anticipation for the future development of “something will happen”.

In addition, you may change the said embodiment as follows.
In the above-described embodiment, two types of normal backgrounds are displayed on the visible display unit H. However, two or more types of normal backgrounds may be displayed on the visible display unit H. For example, a configuration having ten types of normal backgrounds may be used. Further, the normal background image displayed on the visible display portion H may be arbitrarily changed as long as the player can recognize the change of the image when the normal background is changed. For example, the normal background image displayed on the visible display unit H may be an image such as “sea”, “desert”, “jungle”, “sky”, “space”, and the like.

  In the above embodiment, the sub CPU 27a performs a process of determining whether or not the time T in step S10 of the normal background determination process (FIG. 6) is within the notice period (time A + 2 minutes ≦ time T ≦ time A + 7 minutes). There may be no configuration. In that case, without providing the notice period (2 to 7 minutes), when the main CPU 26a determines that it is a big hit, the normal background displayed on the visible display section H may be changed.

  In the above-described embodiment, the sub CPU 27a does not perform the process of determining whether or not to change the normal background based on the extraction of the normal background change random number value in steps S11 and S12 of the normal background determination process (FIG. 6). It may be a configuration. In that case, if the determination in step S10 is affirmative, the normal background may be changed.

  In the above embodiment, the sub CPU 27a may be configured not to perform the process of determining the timing for changing the normal background in step S16 and step S17 of the normal background determination process (FIG. 8). In that case, what is necessary is just to change the normal background displayed on the visible display part H according to the timing initially set beforehand. For example, the timing may be initially set so that the normal background is changed simultaneously with the start of the normal variation of the symbol combination game.

In the above embodiment, the notice period may be arbitrarily changed. For example, it may be changed to 4 minutes to 8 minutes, 3 minutes to 6 minutes, or the like.
In the above embodiment, the timing determination method for changing the normal background in step S16 and step S17 of the normal background determination process (FIG. 8) may be arbitrarily changed. For example, the association between the random value and the timing may be made in units of 30 seconds.

  In the above embodiment, the sub CPU 27a has a timer function for measuring the time T from when the power is turned on. However, a timer function for measuring the time T may be provided on another control board. For example, the main CPU 26a may have a timer function for measuring the time T, the time T may be output as time data, and the sub CPU 27a may input the time data.

  In the embodiment described above, a demonstration effect may be displayed on the visible display unit H when there is no game ball winning in the start winning opening 22 for a certain period of time. In this case, after the demonstration effect for a predetermined time is completed, the visual display unit H displays the normal background based on the background image data stored in the symbol Z that has been confirmed and stopped in the previous symbol combination game and the address α of the RAM 27c. You can do so.

  In the above-described embodiment, only the range of various random number values extracted by the main CPU 26a and the sub CPU 27a is illustrated, and the range of various random numbers, the determination value, and the like can be arbitrarily changed.
