In addition, it can be recognized from the background images HC1 to HC4 including the in-court image GN that the seasons are different at the place “inside the court” (FIGS. 3 (i) to (l)).

  Similarly, in the present embodiment, the player recognizes that the place is different in the same season from the background images configured to include the same (common) seasonal images among the seasonal images KS, KH, KM, and KY. It has become possible to let you. That is, from the background images HA1, HB1, and HC1 including the spring image KS, it can be recognized that the place is different in the season “spring”. From the background images HA2, HB2, and HC2 including the summer image KH, it can be recognized that the place is different in the season “summer”. From the background images HA3, HB3, and HC3 including the autumn image KM, it can be recognized that the place is different in the season “autumn”. From the background images HA4, HB4, and HC4 including the winter image KY, it can be recognized that the place is different in the season “winter”.

  Further, in the present embodiment, the background image that can be displayed on the image display unit GH includes a riverside image GS (indicated by vertical stripes) that does not include any of the seasonal images KS, KH, KM, and KY and indicates the place “river”. A background image HD1 as a specific background is prepared (FIG. 3 (m)). That is, from the background image HD1, the player can recognize only the place “river” without recognizing a specific season.

  Next, the background change mode associated with the execution of the background change effect will be described with reference to FIG. As shown in FIG. 4, the background change effect that can be executed by the pachinko gaming machine 10 of the present embodiment includes a seasonal change effect that executes a background change effect with a seasonal image as a change target, and a background change with a place image as a change target. There is a place change effect where the effect is executed. In the present embodiment, one of the seasonal change effect and the place change effect can be executed “once” for each “one time” symbol variation game.

  In the seasonal change effect, when the seasonal change effect is executed a plurality of times (four times in the present embodiment), the seasonal images KS, KH, KM, and KY show regular changes. Specifically, the seasonal change effect is a seasonal image with the place images GT, GM, and GN constituting the background image displayed on the image display unit GH immediately before the execution of the seasonal change effect fixed (maintained). KS, KH, KM, and KY are changed. Further, the seasonal change effect is such that the seasonal image is changed by one step each time the seasonal change effect is executed in the order of spring image KS → summer image KH → autumn image KM → winter image KY. Further, in the seasonal change effect, when the seasonal image immediately before the execution of the seasonal change effect is the winter image KY, the spring image KS is changed again (looped). Therefore, for example, when the seasonal change effect is executed from the background image HA1 (garden, spring), every time the seasonal change effect is executed, the place “garden” remains “spring” → “summer” → “autumn” → “ It can be recognized as if the season is around, such as “Winter” → “Spring”. In the present embodiment, the spring image KS is in the initial stage, and the winter image KY is in the final stage.

  On the other hand, the place change effect is such that the place images GT, GM, and GN show irregular changes when the place change effect is executed a plurality of times. More specifically, the place change effect is obtained by fixing (maintaining) the seasonal images KS, KH, KM, and KY constituting the background image displayed on the image display unit GH immediately before execution of the place change effect. The place images GT, GM, and GN are changed. That is, in the place change effect, with the seasonal images KS, KH, KM, KY being fixed, the garden image GT to the pre-court image GM or the court image GN, and the pre-court image GM to the garden image GT or the court image GN, The place image is changed from the in-court image GN to the garden image GT or the pre-court image GM. For example, in the case where the place change effect is executed from the background image HA1 (garden, spring), the place “direction” is executed from the place “garden” or the place “in front of the court” or “ It can be recognized as if the place was moved in the same season, such as “in the court”. That is, in the place change effect, the place image can be changed to any place image among the place images different from the place images constituting the background image immediately before the execution of the place change effect.

  The background change effect of the present embodiment includes a specific place change effect that changes the background image from the background images HA1 to HA4, HB1 to HB4, HC1 to HC4 to the background image HD1, and from the background image HD1 to the background image HA1. There is. Note that only the transition from the background image HD1 to the background image HA1 (garden, spring) is permitted by executing the specific place change effect.

Next, the control configuration of the pachinko gaming machine 10 will be described with reference to FIG.

In the present embodiment, the sub-integrated control board 36 constitutes an effect instruction apparatus, and the effect display control board 37 constitutes an effect control apparatus.

Hereinafter, specific configurations of the main control board 35, the sub-integrated control board 36, and the effect display control board 37 will be described.
On the main control board 35, a main control CPU 35a capable of executing control operations in a predetermined procedure, a main control ROM 35b for storing a main control program of the main control CPU 35a, and writing and reading of necessary data. A main control RAM 35c is provided. A main control ROM 35b and a main control RAM 35c are connected to the main control CPU 35a.

  The main control CPU 35a has an upper start switch SW1 that detects a game ball that has entered the upper start prize opening 25, and a lower start port SW2 that detects a game ball that has entered the lower start prize opening 26. It is connected. The main control CPU 35a is connected to a count switch SW3 that detects a game ball that has entered the special winning opening 29 and a normal symbol variation switch SW4 that detects a game ball that has passed through the normal symbol operation gate 30. . The main control CPU 35a is connected with a special symbol display device 23, a normal symbol display device 24, a special symbol hold storage display device Ra, and a symbol display board 39 on which the normal symbol hold storage display device Rb is mounted. Yes. Also, the main control CPU 35a is a special symbol jackpot random number, a special symbol distribution random number, a reach determination random number, a variation pattern random number, a random symbol random number for normal symbols, and so on. The value of the random number is updated every predetermined cycle. Then, the main control CPU 35a executes random number update processing (random number generation processing) for rewriting the value before update by storing (setting) the updated value in the setting area of the main control RAM 35c. Further, the main control CPU 35a updates a timer for measuring time. The main control RAM 35c stores (sets) various pieces of information (random values, timer values, flags, etc.) that are appropriately rewritten during operation of the pachinko gaming machine 10.

  The jackpot determination random number for special symbols is a random number used in the jackpot lottery (jackpot determination) to determine whether or not to win. Further, the special symbol allocation random number is a random number used when determining the big hit symbol as a special symbol to be displayed on the special symbol display device 23 when the big hit is made. The reach determination random number is a random number used in reach lottery (reach determination) for determining whether or not a reach effect is to be formed when a big win is not won in the big win lottery, that is, in the case of a loss. Further, the fluctuation pattern distribution random number is a random number used when selecting and determining a fluctuation pattern. The random number for normal symbol determination for the normal symbol is a random number used in the normal symbol lottery (determination per normal symbol) for determining whether or not to hit the normal symbol.

  In addition to the main control program, the main control ROM 35b stores a plurality of types of variation patterns and various determination values (such as a big hit determination value, a reach determination value, and a normal symbol determination value). The variation pattern is a game effect (display effect, from the time when the symbol (special symbol and decorative symbol) starts to change (the symbol variation game starts) until the symbol is confirmed and stopped (the symbol variation game ends). A pattern serving as a base for a light emission effect and a sound effect) is shown. In the variation pattern, a variation time from the start to the end of the symbol variation game is determined for each variation pattern. In addition, the variation patterns are classified for each effect content including a jackpot effect, an outlier reach effect, and an outlier effect.

  In the big hit effect, the symbol variation game is developed to be a big hit. Specifically, in the jackpot effect, the jackpot symbol combination is displayed on the effect display device 22 after the reach effect, and the jackpot symbol is displayed on the special symbol display device 23. In the outlier reach effect, the symbol variation game is developed in the effect display device 22 so as to finally stop display of the symbol combinations that are out of reach through the reach effect, and the special symbol display device 23 displays the stop symbol in the stop display. Is done. In the off stage effect, the symbol variation game is developed on the effect display device 22 so as to finally stop the final symbol combination without displaying the reach effect, and the special symbol display device 23 stops the stop symbol. Is displayed. In the special symbol display device 23, when the symbol variation game is started, the variation of the symbols is continued until the variation time elapses without performing the reach effect. That is, the reach effect is performed in a symbol variation game using a decorative symbol image displayed on the image display unit GH of the effect display device 22.

  Here, the variation pattern prepared in the pachinko gaming machine 10 of the present embodiment will be described with reference to FIG. FIG. 6 shows a part of a plurality of types of variation patterns stored in the main control ROM 35b.

  The variation pattern P1 is a variation pattern for a loss effect. The fluctuation patterns P2A, P3A, and P4A are fluctuation patterns for outlier reach effects. The variation patterns P2B, P3B, and P4B are variation patterns for a big hit effect.

  The variation patterns P2A and P2B (hereinafter collectively referred to as “variation pattern P2”) are variation patterns that can specify “normal reach production NR” as production content. In the normal reach production NR, after the start of the symbol variation game, the same symbol is derived in a plurality of predetermined symbol sequences (left column and right column in this embodiment) to form a reach, and the remaining symbol sequences (this embodiment) In this case, the middle row) is varied for a predetermined time to derive a symbol.

  The variation patterns P3A and P3B (hereinafter collectively referred to as “variation pattern P3”) specify “super reach production SR1” as the production content, and the variation patterns P4A and P4B (hereinafter collectively “variation pattern P4”). Is a variation pattern capable of specifying “super reach production SR2” as production content. Super reach effects SR1 and SR2 are derived from the same symbol in a plurality of predetermined symbol sequences (left column and right column in this embodiment) after the start of the symbol variation game, and then the normal reach effect NR is obtained. It is an effect that is performed through the development of reach production. The super reach effects SR1 and SR2 are effects in which a character or the like appears and a symbol is derived in the middle row by the action of the character. Normally, in a pachinko machine, the big hit reliability of the super reach production SR1 and SR2 is set higher than the big hit reliability of the normal reach production NR, and when the big hit lottery is won, the super reach production SR1 and SR2 are set. The selectivity of the variation pattern to be executed is increased.

  The jackpot determination value is a determination value used in the jackpot lottery, and is determined from numerical values that can be taken by the jackpot determination random number for special symbols (all 1471 integers from 0 to 1470). The reach determination value is a determination value used in reach determination, and is determined from numerical values (a total of 241 integers from 0 to 240) that can be taken by random numbers for reach determination. The judgment value per ordinary symbol is a judgment value used in the lottery per ordinary symbol, and is determined from the numerical values (all 107 different integers from 0 to 106) that can be taken by the random number for judgment per ordinary symbol.

Next, the sub integrated control board 36 will be described with reference to FIG.
On the sub-general control board 36, an overall control CPU 36a capable of executing control operations in a predetermined procedure, an overall control ROM 36b for storing an overall control program of the overall control CPU 36a, and writing and reading of necessary data An overall control RAM 36c is provided. The overall control CPU 36a is connected to the overall control ROM 36b and the overall control RAM 36c. The overall control CPU 36a is equipped with a timer function, and measures time at a predetermined timing (for example, timing at which a symbol variation game is started). In addition to the overall control program, the overall control ROM 36b stores various tables to be referred to when determining various effects.

  Further, the overall control CPU 36a updates the values of various random numbers such as effect distribution random numbers at predetermined intervals. Then, the overall control CPU 36a executes random number update processing (random number generation processing) for rewriting the pre-update value by storing (setting) the updated value in the setting area of the overall control RAM 36c. The random number for effect distribution is a random number used when determining whether to execute the background change effect or determining the change content of the background change.

Next, the effect display control board 37 will be described.
On the effect display control board 37, a display control CPU 37a capable of executing a control operation in a predetermined procedure, a display control ROM 37b for storing a display control program of the display control CPU 37a, and writing and reading of necessary data. A display control RAM 37c is provided. An effect display device 22 is connected to the display control CPU 37a. Further, the display control CPU 37a of the present embodiment has a timer function, and measures time at a predetermined timing (for example, timing at which a symbol variation game is started). The display control ROM 37b stores various image data (image data such as symbols, backgrounds, characters, characters, etc.).

Hereinafter, the control contents executed by the main control board 35, the sub general control board 36, and the effect display control board 37 will be described.
First, the main control board 35 will be described.

  The main control CPU 35a of the main control board 35 executes a special symbol input process every predetermined control cycle (for example, every 4 ms). In this special symbol input process, the main control CPU 35a inputs a detection signal output by the start port switches SW1 and SW2 that detect the game ball when the game ball enters the upper start winning port 25 or the lower start winning port 26. Then, a hold determination is made as to whether or not the number of reserved symbols for special symbols stored in the main control RAM 35c is less than the upper limit number (4 in this embodiment). If the determination result of the hold determination is affirmative (the number of reserved symbols for special symbols <4), the main control CPU 35a adds (+1) the number of reserved symbols for special symbols to “1”, and the reserved memory for special symbols. Rewrite the number. Further, the main control CPU 35a lights up the number of special symbol holding light emitting units (holding lamps) corresponding to the number of reserved memories after the rewriting as the number of reserved memories for special symbols is rewritten. Further, when the main control CPU 35a determines that the hold determination is affirmative, the main control CPU 35a acquires the value of the special jackpot determination random number and the value of the special design distribution random number from the main control RAM 35c, and obtains the values. It is stored in a predetermined storage area of the main control RAM 35c in association with the number of reserved symbols for special symbols. When the determination result of the hold determination is negative (holding memory count = 4), the main control CPU 35a does not rewrite the reserved memory count for the special symbol exceeding the upper limit number, and the value of each random number described above is not changed. Do not get.

  Further, the main control CPU 35a executes a special symbol start process every predetermined control cycle (for example, every 4 ms). In this special symbol start process, the main control CPU 35a first determines whether or not the symbols (special symbols and decorative symbols) are changing (during the execution of the symbol change game), and whether or not a big hit game is being played. To do. When the determination result is affirmative, the main control CPU 35a ends the special symbol start process.

  On the other hand, if the determination result is negative (when it is not fluctuating and is not a big hit game), the main control CPU 35a reads the number of reserved symbols for special symbols stored in the main control RAM 35c, It is determined whether or not the number of reserved memories is greater than “0 (zero)” (whether or not there is a pending symbol variation game). If this determination result is negative (the number of reserved memories is “0”), the main control CPU 35a ends the special symbol start process. On the other hand, if the determination result is affirmative (the number of reserved memories is larger than “0”), the main control CPU 35a subtracts “1” from the number of reserved memories for the special symbol, and then the predetermined number in the main control RAM 35c. Read the value of the special jackpot determination random number stored in the storage area. Then, the main control CPU 35a compares the read jackpot determination random number value with the jackpot determination value stored in the main control ROM 35b, and determines whether or not it is a big hit (hit lottery).

  When the determination result of the big hit determination is affirmative (the value of the big hit determination random number matches the big hit determination value), the main control CPU 35a determines the big hit. The CPU 35a for main control which has determined the big hit determines the big hit symbol as a special symbol to be confirmed and stopped in the symbol variation game executed by the special symbol display device 23 based on the value of the special symbol distribution random number. In addition, the main control CPU 35a that has determined the big hit acquires the random value for fluctuation pattern distribution from the main control RAM 35c, and selects and determines the fluctuation pattern for the big hit effect based on the acquired value.

  On the other hand, when the determination result of the big hit determination is negative (the value of the special jackpot determination random number and the big hit determination value do not match), the main control CPU 35a determines the deviation. Then, the main control CPU 35a which has determined the detachment determines whether or not to execute the detachment effect by random number lottery (a random number for reach determination and a reach determination value). When the execution of the outlier reach effect is determined, the main control CPU 35a determines the off symbol as a special symbol to be displayed on the special symbol display device 23 in a fixed stop display. Further, the main control CPU 35a acquires a random value for variation pattern distribution from the main control RAM 35c, and selects and determines a variation pattern for shift reach production based on the acquired value. On the other hand, when the non-execution of the outlier reach effect is determined, the main control CPU 35a determines the out symbol in the same manner as described above. Further, the main control CPU 35a acquires a random value for distribution pattern distribution from the main control RAM 35c, and selects and determines a shift pattern for deviation effect based on the acquired value.

  The main control CPU 35a having determined the special symbol and the variation pattern generates a predetermined control command, and outputs the generated control command to the sub overall control board 36 (overall control CPU 36a) at a predetermined timing. Specifically, the main control CPU 35a first outputs a variation pattern designation command for instructing the variation pattern and for instructing the start of the symbol variation game at the start of the symbol variation game. The main control CPU 35a outputs a special symbol stop symbol designating command for designating a special symbol, after outputting the variation pattern designating command. Then, the main control CPU 35a outputs a symbol stop command for instructing the end of the symbol variation game (determination of symbol determination) when the variation time determined in the instructed variation pattern has elapsed as the variation time elapses. .

  Further, the main control CPU 35a controls the display content of the special symbol display device 23 with the start of the symbol variation game. That is, the main control CPU 35a starts the variation of the special symbol by starting the symbol variation game, and confirms and stops the special symbol (the winning symbol or the off symbol) determined when the variation time set in the determined variation pattern has elapsed. Display.

  Then, when determining the big hit, the main control CPU 35a starts the control of the big hit game after the symbol change game based on the determined change pattern, and gives a predetermined control to the sub overall control board 36 (overall control CPU 36a). The control command is output at a predetermined timing.

  The main control CPU 35a outputs an opening command at the start of the big hit game, outputs a round command at the start of each round game, and outputs an ending command at the end. The opening command instructs the start of the opening effect, the round command instructs the start of the round game (round effect), and the ending command instructs the start of the ending effect. Further, the main control CPU 35a outputs a release signal for opening the big winning opening 29 at the start of each round game in the big hit game. The opening signal is output to the actuator of the special winning opening door 28, the actuator is actuated by the opening signal, and the large winning opening door 28 is opened. In addition, the main control CPU 35a measures a predetermined round game time for each round game in the big hit game, and counts the number of game balls that have entered the big winning opening 29 during the round game. Then, the main control CPU 35a closes the big winning opening 29 by satisfying one of the end conditions that the round game time has passed and the upper limit number of game balls have entered in the big hit game. A closing signal for outputting the signal is output. The closing signal is output to the actuator of the special winning opening door 28, the actuator is actuated by the closing signal, and the special winning opening door 28 is closed.

  Then, the main control CPU 35a that ended the big hit game, when the number of reserved symbols for the special symbol at the time of the end of the big hit game is "1" or more, the next symbol variation game based on the start hold ball Let it begin. On the other hand, when the number of reserved symbols for the special symbol at the end of the big hit game is “0”, the main control CPU 35a plays the symbol variation game until the game ball enters the start winning opening and the start condition is satisfied. Wait without running.

Next, the contents of control executed by the sub integrated control board 36 will be described.
The central control CPU 36a of the sub general control board 36, when a change pattern designation command is input, outputs the command to the effect display control board 37 and the sound / lamp control board 38. Further, when the overall control CPU 36a inputs a stop symbol designation command for a special symbol, the overall control CPU 36a determines a decoration symbol to be confirmed and stopped and displayed on the effect display device 22 in accordance with the stop symbol designation of the special symbol corresponding to the command. A stop symbol designating command for the decorative symbol designating the decorative symbol is output to the effect display control board 37.

  More specifically, if the stop symbol (special symbol) designated by the special symbol stop symbol designation command is a jackpot symbol, the overall control CPU 36a can recognize the jackpot as a combination of ornament symbols. Determine the symbol combination. In addition, when the stop symbol (special symbol) designated by the special symbol stop symbol designation command is an outlier symbol, the overall control CPU 36a determines an off symbol combination that can recognize the loss. At this time, when the fluctuation pattern for the outlier reach effect is instructed, the overall control CPU 36a determines a symbol combination that can recognize the outlier including the reach formation symbol. On the other hand, when the variation pattern for the offending effect is instructed, the overall control CPU 36a determines a combination of outliers that can recognize an outlier that does not include the reach formation symbol.

When the overall control CPU 36a inputs the all symbols stop command, the overall control CPU 36a outputs the command to the effect display control board 37 and the sound / lamp control board 38.
Next, the control content related to the big hit game executed by the overall control CPU 36a will be described.

  When the opening control command, the round command, and the ending command are input, the overall control CPU 36a determines the effect content of the opening effect, the effect content of the round effect, and the effect content of the ending effect according to these commands. Then, the overall control CPU 36a outputs an effect instruction command for instructing the determined effect contents to the effect display control board 37 and the sound / lamp control board 38, respectively.

Next, the effect display control board 37 will be described.
When the change pattern designation command is input, the display control CPU 37a of the effect display control board 37 selects the effect content according to the instruction content of these commands, and causes the image display unit GH to play the symbol variation game with the effect content. Controls the display content of. At this time, the display control CPU 37a generates display data for displaying an image according to the effect contents using the image data of the display control ROM 37b based on the selected effect contents. Then, the display control CPU 37a measures the elapsed time from the start of the game with the start of the symbol variation game, and displays an image displayed on the image display unit GH based on the measured time and display data. Switch every control cycle. Then, the display control CPU 37a derives the decorative symbol designated by the decorative symbol stop symbol designation command in the symbol variation game, and displays the image so that the symbol combination by the decorative symbol is fixedly stopped and displayed by the input of the symbol stop command. The display content of the part GH is controlled to end the symbol variation game.

  Further, the display control CPU 37a causes the opening effect, the round effect, and the ending effect to be performed in accordance with the effect instruction command for the opening effect, the effect instruction command for the round effect, and the effect instruction command for the ending effect during the big hit game. The display content of the image display unit GH is controlled. That is, the display control CPU 37a uses the image data in the display control ROM 37b to generate display data for displaying an image according to the effect contents, and displays the display contents on the image display unit GH, as in the case of the symbol variation game. To control.

Next, a control configuration relating to the execution of the background change effect will be described with reference to FIGS.
FIG. 7 shows control commands output to the effect display control board 37 (display control CPU 37a) in order to control the background image displayed on the image display unit GH by the sub-general control board 36 (overall control CPU 36a). Has been.

  As shown in FIG. 7, command values [9000H] to [900CH] (“H” indicates that they are written in hexadecimal notation) are command values (designated values) that specify the background image. . The command value [9020H] is a command value for instructing execution of a seasonal change effect. Command values [9030H] to [9033H] are command values for instructing execution of the place change effect. The command values [9040H] and [9041H] are command values for instructing execution of the specific place change effect.

  In the present embodiment, command values [9001H] to [900BH] among command values that can specify a background image are command values that are calculated (generated) by the overall control CPU 36a and the display control CPU 37a based on various parameters. ing. For this reason, command values [9001H] to [900BH] are not stored in advance in the overall control ROM 36b and the display control ROM 37b of the present embodiment. On the other hand, the command value [900CH] that is not calculated based on various parameters among the command values that can specify the background image, and the command value [9000H] that may not be calculated are the overall control ROM 36b and the display control ROM 37b. Is stored in advance. Command values [9020H], [9030H] to [9033H], [9040H], and [9041H] for instructing execution of the background change effect are stored in advance in the overall control ROM 36b. Control for calculating command values [9000H] to [900BH] based on various parameters will be described later.

  The command values [9000H] to [900BH] for specifying each background image in the present embodiment specify a different background image for each command value. The command value for designating each background image has a plurality of background blocks (in this embodiment) for every four command values that continue in ascending order from the command value [9000H] at the head at equal intervals (“1” in this embodiment). Is divided into 3). In this embodiment, a background image that includes different location images GT, GM, and GN for each of the three background blocks is specified. Specifically, each command value belonging to the background block composed of command values [9000H] to [9003H] specifies a background image including the garden image GT, and the command values [9004H] to [9007H]. Each command value belonging to the background block consisting of specifies a background image including the pre-courtroom image GM. Similarly, each command value belonging to the background block composed of command values [9008H] to [900BH] specifies a background image including the court image GN. In other words, in this embodiment, it is possible to grasp that the background image is divided into a plurality of background blocks by dividing the command value for specifying the background image into a plurality of background blocks.

  Also, each command value belonging to each background block specifies a background image that includes seasonal images KS, KH, KM, and KY (first background elements). More specifically, in the present embodiment, four command values that are consecutive at equal intervals (“1” in the present embodiment) from the command value that is the head (minimum value) among command values belonging to each background block. In the ascending order, the background image including each season image is specified in the order of the spring image KS as the initial stage of the seasonal change effect to the winter image KY as the final stage. In addition, each command value belonging to each background block specifies a different background image configured to include different seasonal images. For example, in the background block consisting of command values [9004H] to [9007H], the command value [9004H] at the head identifies the background image HB1 (spring before the court, spring) including the spring image KS, and the next command value [9005H ] Specifies the background image HB2 (in front of the court, summer) including the summer image KH. Similarly, the next command value [9006H] specifies the background image HB3 (autumn before the court, autumn) including the autumn image KM, and the next command value [9007H] includes the background image HB4 (before the court, winter) including the winter image KY. ) Is specified.

  In the pachinko gaming machine 10 of the present embodiment, the command value for specifying the background image can be calculated (generated) based on various parameters from the association of the command value array and the background image.

  That is, when executing a seasonal change effect, a command value for specifying a background image immediately before the execution of the seasonal change effect is used as a reference parameter, and “1” is added to the reference parameter as a change parameter indicating a seasonal change. The command value of the background image configured to include the next seasonal image can be calculated. In the present embodiment, this reference parameter is a parameter corresponding to the current background. In the present embodiment, the change parameter indicating the seasonal change is the parameter corresponding to the change content of the background change and the first parameter. For example, a command that can specify the background image HC2 (in the courtroom, summer) by adding the change parameter “1” to the command value [9008H] (reference parameter) that can identify the background image HC1 (in the courtroom, spring) The value [9009H] can be calculated.

  Further, when a command value that can specify a background image including a spring image KS that is an initial stage is calculated from a command value that can specify a background image including a winter image KY that is a final stage, the change parameter “1”. In addition to “4”, “−4” is added. In the present embodiment, the value “−4” to be added is an additional parameter for causing the seasonal change to change most (loop). For example, the background image HC1 (in the courtroom, spring) is identified by adding the change parameter “1” and the additional parameter “−4” to the command value [900BH] that can identify the background image HC4 (in the courtroom, winter). A possible command value [9008H] can be calculated.

  In addition, when executing a place change effect, a command value for specifying a background image immediately before the execution of the place change effect is used as a reference parameter, and a seasonal image is added by adding a change parameter indicating a place change to the reference parameter. The command value of the background image configured to include different place images can be calculated while being fixed. The change parameters indicating the location change in the present embodiment are “4”, “−4”, “8”, and “−8”. The change parameters indicating the place change in the present embodiment are each composed of multiples of “4”, which is the number of stages of seasonal change effects (number of types of seasonal images). In the present embodiment, the change parameter indicating the place change is the parameter corresponding to the change content of the background change and the second parameter.

  For example, in this embodiment, the background image HB1 to HB4 including the corresponding seasonal image can be specified by adding the change parameter “4” to each command value (reference parameter) for specifying the background images HA1 to HA4. Command values can be calculated. Further, for example, a command value that can identify the background images HC1 to HC4 including the corresponding seasonal images by adding the change parameter “8” to each command value (reference parameter) that identifies the background images HA1 to HA4. Can be calculated. More specifically, for example, by adding the change parameter “4” to the command value [9000H] of the background image HA1 (garden, spring), the command value [9004H] of the background image HB1 (pre-courtroom, spring) Can be calculated.

  The command value [900CH] is a command value that can specify the background image HD1. As described above, the background image HD1 does not include the seasonal images KS, KH, KM, and KY, and is composed of the riverside image GS. In the present embodiment, the command value [900CH] that can specify the background image HD1 is the specific designated value.

  The command value [9020H] of this embodiment is a command value that designates execution of a seasonal change effect. In this command value [9020H], “1” is set as the value of the change parameter. In addition, the command values [9030H] to [9033H] of the present embodiment are command values for instructing execution of the place change effect. In these command values [9030H] to [9033H], “4”, “−4”, “8”, and “−8” are set as change parameter values, respectively.

  In this embodiment, the command value [9020H] specifies execution of the seasonal change effect and “change the seasonal image by one step” as the change content of the background change. Therefore, in this embodiment, the command value [9020H] is not a command value that can specify from only the command value to “which background image to change”. Similarly, the command values [9030H] to [9033H] of the present embodiment specify “change the place image” as the execution contents of the place change effect and the change contents of the background change. For this reason, in this embodiment, the command values [9030H] to [9033H] are not command values that can specify from only the command value to “which background image to change”.

  On the other hand, the command value [9040H] specifically specifies “change to the background image HD1” as the execution of the specific place change effect and the change content of the background change. Further, the command value [9041H] specifically specifies “change to the background image HA1” as the execution of the specific place change effect and the change content of the background change. For this reason, no change parameter is set for the command values [9040H] and [9041H].

  Next, the selection pattern selection table TA for selecting the selection patterns SP0 to SP6 used when the overall control CPU 36a determines whether or not the background change effect can be executed and the change contents of the background change will be described with reference to FIG. . The selection pattern selection table TA is stored in the overall control ROM 36b.

  As shown in FIG. 8, in the selection pattern selection table TA, one of the selection patterns SP0 to SP6 is associated with each combination of the variation patterns P1 to P4 and the background image. . In FIG. 8, the combination of the variation patterns P2 to P4 and the background image HD1 (river image GS) is hatched to indicate that the process of selecting the selection pattern is not performed. In the selection pattern selection table TA, for example, when the background image is the background image HA1 to HA4 (garden image GT) and the variation pattern P2B is designated by the variation pattern designation command, the selection pattern SP3 is selected. The Similarly, when the background image is the background image HD1 (river bank image GS) and the variation pattern P1 is designated by the variation pattern designation command, the selection pattern SP0 is selected.

  Next, the background control tables TB1 to TB4 used by the overall control CPU 36a to determine whether or not the background change effect can be executed and the background change contents will be described with reference to FIGS. 9 (a) to 9 (d). The background change tables TB1 to TB4 are stored in the overall control ROM 36b.

  As shown to Fig.9 (a), in background change table TB1 referred when a background image is background image HA1-HA4 (garden image GT), each selection pattern SP0-SP6 and a background change effect are not performed. For each combination of “no background change” and each change content of the background change, a predetermined number of values that can be taken by the random number for effect distribution (all 0-996 integer values) are assigned. In the background change table TB1, “change in place (+4)” to be changed to the place “in front of the court” (pre-court image GM) and the place “in the court” (in-court image GN) as the change contents of the background change. 3), “place change (+8)” to be changed to “” and “change to background image HD1” to be changed to the background image HD1. In the present embodiment, when the overall control CPU 36a determines “no background change”, it means that the execution of the background change effect is determined (non-execution), and when the change content of the background change is determined, This means that execution (change) of the change effect is determined. The overall control CPU 36a of this embodiment determines the change content of the background change by determining the command value corresponding to each change content of the background change. In the background change tables TB1 to TB3, combinations in which the value of the random number for effect distribution is not distributed are shaded.

  In the background change table TB1, for example, when the selection pattern SP1 is selected, “no background change” is determined with a probability of 806/977, and “seasonal change (+1)” is determined with a probability of 91/977. Similarly, in the background change table TB1, when the selection pattern SP1 is selected, “place change (+4)” with a probability of 33/977, “place change (+8)” with a probability of 33/977, 34 / "Change to background image HD1" is determined with a probability of 977.

  FIG. 9B shows a background change table TB2 that is referred to when the background image is the background image HB1 to HB4 (pre-courtroom image GM), and FIG. 9C shows the background image as the background image HC1. A background change table TB3 referred to in the case of HC4 (in-court image GN) is shown. In the background change tables TB2 and TB3, possible values of the random number for effect distribution (for each combination of the selection patterns SP0 to SP4, “no background change” that does not execute the background change effect, and each change content of the background change ( A total of 997 different integer values from 0 to 996) are distributed by a predetermined number.

  The background change table TB2 includes “place change (−4)” to be changed to the place “garden” (garden image GT) and the place “inside the court” (inside court image GN) as the change contents of the background change. There are set “place change (+4)” to be changed to “change” and “change to background image HD1” to be changed to background image HD1. Similarly, in the background change table TB3, “change in location (−8)” to be changed to the place “garden” (garden image GT) and the place “in front of the court” (in front of the court) as the change contents of the background change. Three are set: “place change (−4)” to be changed to image GM) and “change to background image HD1” to be changed to background image HD1. In the present embodiment, when the background images at the time of inputting the variation pattern designation command are the background images HB1 to HB4 and HC1 to HC4 (pre-court image GM, court image GN), the selection pattern SP5 in the selection pattern selection table TA. , SP6 is not selected. Therefore, the selection patterns SP5 and SP6 are not associated with the background change tables TB2 and TB3.

  FIG. 9D shows a background change table TB4 that is referred to when the background image is the background image HD1 (river image GS). In the background change table TB4, for each combination of the selected pattern SP0, “no background change” that does not execute the background change effect, and the change contents of the background change, the possible values of the effect distribution random numbers (all of 0 to 996) can be taken. 997 different integer values) are distributed by a predetermined number. In the background change table TB4, “change to background image HA1” to be changed to the background image HA1 (garden, spring) is set as the change content of the background change.

  In the present embodiment, when the background image at the time of inputting the variation pattern designation command is the background image HD1 (river image GS), the selection patterns SP1 to SP6 are not selected in the selection pattern selection table TA. For this reason, the selection patterns SP1 to SP6 are not associated with the background change table TB4.

  Next, background processing performed by the overall control CPU 36a of the present embodiment when a variation pattern designation command is input will be described with reference to the flowchart of FIG. In the present embodiment, the overall control CPU 36a that executes the following background processing functions as a change content determination unit, a background calculation unit, a specific change determination unit, and a specific background determination unit.

  As shown in FIG. 10, the overall control CPU 36a displays the current background image displayed on the effect display device 22 (image display unit GH) when a variation pattern designation command is input (at the start of the symbol variation game). The command value to be specified is acquired from a predetermined area of the overall control RAM 36c (step S1). In the present embodiment, the command value of the current background image is the reference parameter.

  Next, the overall control CPU 36a determines whether or not the background change effect can be executed, and determines the change content of the background change when the background change effect is executed (step S2). Specifically, first, the overall control CPU 36a identifies the type of the current background image from the command value of the current background image. Next, the overall control CPU 36a selects a selection pattern with reference to the selection pattern selection table TA based on the specified background image type and the variation pattern designated by the variation pattern designation command.

  Next, the overall control CPU 36a selects one background change table from the background change tables TB1 to TB4 according to the specified type of background image. Then, the overall control CPU 36a refers to the selected background change table based on the value of the effect distribution random number acquired from the overall control RAM 36c and the selected selection pattern, and determines whether or not the background change effect can be executed. The change content of the background change when the production is executable is determined. That is, the overall control CPU 36a determines “no background change” in the process of step S2 or determines a command value (content of change of background change) of a control command instructing execution of a background change effect.

  Next, the overall control CPU 36a determines whether or not “no background change” is determined in the process of step S2 (step S3). If the determination result of step S3 is affirmative, the overall control CPU 36a outputs (transmits) a background image command for designating the command value of the current background image acquired in step S1 to the effect display control board 37 (step) S4). Thereafter, the overall control CPU 36a ends the background processing.

  If the determination result in step S3 is negative, the overall control CPU 36a determines whether or not the change content of the background change determined in the process of step S2 is “seasonal change (+1)” (step S5). . Specifically, the overall control CPU 36a determines whether or not the command value determined in step S2 is [9020H]. If the determination result of step S5 is affirmative, the change parameter “1” is added to the command value (reference parameter) of the current background image acquired in the process of step S1 (step S6). Next, the overall control CPU 36a determines whether or not the command value calculated in step S6 is equal to or less than the maximum command value among the command values included in the background block to which the command value of the current background image belongs ( Step S7). That is, the overall control CPU 36a determines whether or not the current seasonal change effect is a seasonal change effect from the winter image KY to the spring image KS by the determination process in step S7.

  If the determination result in step S7 is affirmative, the overall control CPU 36a sets the command value calculated in step S6 as the command value of the background image after the change in the background change effect, and places the command value in a predetermined area of the overall control RAM 36c. Set (step S8). The command value stored in step S8 is the “current background image command value” at the start of the next symbol variation game. Next, the overall control CPU 36a provides the effect display control board 37 with the background image command for specifying the command value of the current background image acquired in step S1 and the season change command [9020H] for instructing execution of the season change effect. Output (step S4). Thereafter, the overall control CPU 36a ends the background processing.

  On the other hand, if the determination result of step S7 is negative, the overall control CPU 36a adds the additional parameter “−4” to the command value calculated in the process of step S6 (step S9). Next, the overall control CPU 36a uses the command value calculated in step S9 as the command value of the background image after the change in the background change effect, and sets the command value in a predetermined area of the overall control RAM 36c (step S40). S8). Then, the overall control CPU 36a executes the process of step S4 and ends the background process.

  If the determination process in step S5 is negative, the overall control CPU 36a determines whether or not the change content of the background change determined in the process in step S2 is “place change (± 4, ± 8)”. (Step S10). Specifically, the overall control CPU 36a determines whether or not the command values determined in step S2 are [9030H] to [9033H]. If the determination result in step S10 is affirmative, the overall control CPU 36a sets the change parameter “± 4” set to the determined command value to the command value (reference parameter) of the current background image acquired in the process of step S1. Alternatively, “± 8” is added (step S11). The overall control CPU 36a sets the command value calculated in step S11 as the command value of the background image after the change in the background change effect, and sets the command value in a predetermined area of the overall control RAM 36c (step S8). . Thereafter, the overall control CPU 36a performs the effect display control on the background image command that specifies the command value of the current background image acquired in step S1 and the place change commands [9030H] to [9033H] that instructs execution of the place change effect. Output to the substrate 37 (step S4). Thereafter, the overall control CPU 36a ends the background processing.

  If the determination result in step S10 is negative, the overall control CPU 36a acquires a command value for specifying a background image corresponding to the change content of the background change from the overall control ROM 36b (step S12). In the present embodiment, when the determination results in steps S3, S5, and S10 are all negative, the change content of the background change is “change to background image HA1 (command value [9041H])” or “change to background image HD1 (command Value [9040H]) "is determined. When the command value [9041H] is determined, the overall control CPU 36a acquires the command value [9000H] that can specify the background image HA1 (garden, spring) from the overall control ROM 36b. When the command value [9040H] is determined, the overall control CPU 36a acquires the command value [900CH] that can specify the background image HD1 (riverside) from the overall control ROM 36b. Then, the overall control CPU 36a sets the command value acquired in step S12 as the command value of the background image after the change in the background change effect, and sets the command value in a predetermined area of the overall control RAM 36c (step S8). . Thereafter, the overall control CPU 36a effects the background image command for specifying the command value of the current background image acquired in step S1 and the place change commands [9040H] and [9041H] for instructing execution of the specific place change effect. Output to the control board 37 (step S4). Thereafter, the overall control CPU 36a ends the background processing.

  In the present embodiment, the background image command is output to the effect display control board 37 every time the symbol variation game is started by executing the background processing. In this embodiment, when outputting the background image command and the background change command, the background image command and the background change command (seasonal change command, place change command) are output to the effect display control board 37 in this order. Yes.

  Next, processing (background confirmation processing and background change processing) for controlling the background image displayed on the image display unit GH by the display control CPU 37a of the effect display control board 37 will be described. In the present embodiment, the display control CPU 37a that executes the following processing functions as background calculation means, execution control means, and specific background determination means.

  First, the background confirmation processing that is performed when the display control CPU 37a inputs a background image command together with the variation pattern designation command from the sub overall control board 36 (overall control CPU 36a) will be described.

  When the display control CPU 37a inputs a background image command together with the variation pattern designation command from the sub-general control board 36, the current background image displayed on the image display unit GH at the input time (the start time of the symbol variation game). Is obtained from the display control RAM 37c. Next, the display control CPU 37a determines whether or not the input background image command value matches the acquired command value of the current background image. When the command value of the input background image command and the command value of the current background image do not match (when they do not match), the display control CPU 37a displays the image display unit GH on the background image specified by the input background image command. Rewrite the contents. Further, the display control CPU 37a having rewritten the background image rewrites and stores the command value of the input background image command in the predetermined area of the display control RAM 37c as the command value of the current background image, and ends the background confirmation processing. If the command value of the input background image command matches the command value of the current background image, the display control CPU 37a ends the background confirmation process.

  As a result of executing the background confirmation processing, in this embodiment, when the value of the background image command and the command value of the current background image do not match, the background image designated by the background image command is almost simultaneously with the start of the symbol variation game. It will be rewritten.

  Next, background change processing performed when the display control CPU 37a inputs a background change command (seasonal change command and place change command) together with the background image command will be described.

  First, the case where the season change command [9020H] is input following the background image command will be described. The display control CPU 37a acquires the command value of the current background image from a predetermined area of the display control RAM 37c after the above-described background confirmation processing is completed. The command value of the acquired current background image becomes a reference parameter. The display control CPU 37a calculates the command value by adding the change parameter “1” set in the seasonal change command [9020H] to the acquired command value of the current background image. Next, the display control CPU 37a determines whether or not the calculated command value is equal to or less than the maximum command value among the command values included in the background block to which the command value of the current background image belongs. When the determination result of the loop determination is affirmative, the display control CPU 37a stores the calculated command value in a predetermined area of the display control RAM 37c as the command value of the background image after the change in the background change effect. On the other hand, when the determination result of the loop determination is negative, the display control CPU 37a calculates a command value by further adding the additional parameter “−4” to the calculated command value, and changes the command value to the background after the change. The image command value is stored in a predetermined area of the display control RAM 37c. Then, the display control CPU 37a controls the display content of the image display unit GH so as to perform a seasonal change effect that changes to the background image specified by the command value of the background image after the change in the calculated background change effect.

  Next, a case where the place change commands [9030H] to [9033H] are input following the background image command will be described. The display control CPU 37a obtains the command value (reference parameter) of the current background image from a predetermined area of the display control RAM 37c after the above-described background confirmation processing is completed. Next, the display control CPU 37a calculates a command value by adding the change parameters “± 4” and “± 8” set in the place change command to the command value of the current background image. The display control CPU 37a stores the calculated command value in a predetermined area of the display control RAM 37c as the command value of the background image after the change in the background change effect. Then, the display control CPU 37a controls the display content of the image display unit GH so as to perform a seasonal change effect that changes to the background image specified by the command value of the background image after the change in the calculated background change effect.

  Next, a case where the place change commands [9040H] and [9041H] are input after the background image command will be described. The display control CPU 37a displays the command value of the background image corresponding to the change content of the background change (changed to the background images HA1 and HD1) designated by the input place change command after the above-described background confirmation processing is completed. Obtained from the ROM 37b. Specifically, when the location change command [9040H] is input, the display control CPU 37a acquires the command value [900CH], while when the location change command [9041H] is input, the display control CPU 37a receives the command value. [9000H] is acquired. The display control CPU 37a stores the acquired command value in a predetermined area of the display control RAM 37c as the command value of the background image after the change in the background change effect. Then, the display control CPU 37a controls the display content of the image display unit GH so as to perform a seasonal change effect that changes to the background image specified by the command value of the background image after the change in the acquired background change effect.

  Next, the execution mode of the background change effect in the pachinko gaming machine 10 of the present embodiment and the calculation mode of the command value of the background image after the change in the background change effect will be described with reference to FIG.

  First, as shown in FIG. 11A, the background image HA1 (garden, spring) is displayed on the image display unit GH immediately before the start of the symbol variation game. Next, when the overall control CPU 36a determines “seasonal change (+1)” in response to the input of the variation pattern designation command, the overall control CPU 36a and the display control CPU 37a set the command value [9000H] as the reference parameter. The change parameter “1” is added to calculate the command value [9001H] of the background image after the change in the background change effect. As shown in FIG. 11B, the image display unit GH changes from the background image HA1 (garden, spring) to the background image HA2 (garden, summer). Similarly, when the overall control CPU 36a determines “seasonal change (+1)” as the change content of the background change, the overall control CPU 36a and the display control CPU 37a add the change parameter “9001H” to the change parameter “9001H”. +1 ”is added to calculate the command value [9002H]. The overall control CPU 36a and the display control CPU 37a use the calculated command value [9002H] as the command value of the background image after the change in the background change effect. Then, as shown in FIG. 11C, the image display unit GH changes from the background image HA2 (garden, summer) to the background image HA3 (garden, autumn).

  When the overall control CPU 36a determines “place change (+4)” as the change content of the background change, the overall control CPU 36a and the display control CPU 37a add the change parameter “4” to the command value [9002H] as the reference parameter. ] Is added to calculate the command value [9006H]. The overall control CPU 36a and the display control CPU 37a use the calculated command value [9006H] as the command value of the background image after the change in the background change effect. Then, as shown in FIG. 11 (d), in the image display unit GH, the background image HA3 (garden, autumn) changes to the background image HB3 (in front of the court, autumn).

  Next, as shown in FIG. 11 (e), after the change to the background image HB4 (before the court, winter) by execution of the seasonal change effect, the overall control CPU 36a further displays “season change (+1) as the change content of the background change. ) ”Is determined, the overall control CPU 36a and the display control CPU 37a add the change parameter“ 1 ”to the command value [9007H] as the reference parameter to calculate the command value [9008H]. Then, the overall control CPU 36a and the display control CPU 37a have the calculated command value [9008H] exceed the maximum command value [9007H] among the background blocks [9004H] to [9007H] to which the command value of the current background image belongs. Therefore, the additional parameter “−4” is further added to calculate the command value [9004H]. Then, the overall control CPU 36a and the display control CPU 37a use the calculated command value [9004H] as the command value of the background image after the change in the background change effect. Then, as shown in FIG. 11 (f), in the image display unit GH, the background image HB4 (before the court, winter) changes to the background image HB1 (before the court, spring).

  Next, when the overall control CPU 36a determines “specific place change (change to background image HD1)” as the change content of the background change, the overall control CPU 36a and the display control CPU 37a select the background image corresponding to the change content. The command value [900CH] is acquired, and the acquired command value is set as the command value of the background image after the change in the background change effect. Then, as shown in FIG. 11G, in the image display unit GH, the background image HB1 (in the court, spring) changes to the background image HD1 (riverside).

  Similarly, when the overall control CPU 36a determines “change in specific location (change to background image HA1)” as the change content of the background change, the overall control CPU 36a and the display control CPU 37a change the background image corresponding to the change content. The command value [9000H] is acquired, and the acquired command value is set as the command value of the background image after the change in the background change effect. Then, as shown in FIG. 11 (h), in the image display unit GH, the background image HD1 (riverside) changes to the background image HA1 (garden, spring).

As described above, according to the present embodiment, the following operational effects are obtained.
(1) In this embodiment, it corresponds to the change parameter corresponding to the change content of the background change determined by the overall control CPU 36a and the current background image displayed as an image on the effect display device 22 (image display unit GH). Based on the reference parameter (command value), the command value of the background image after the change in the background change effect is calculated. In the present embodiment, the background change effect is executed so as to change the background image specified by the calculated command value of the background image. For this reason, in this embodiment, since the command value for specifying the background image after the change can be calculated from the change parameter and the reference parameter, it is possible to specify in advance information (more specifically, There is no need to store flags and command values. For this reason, in this embodiment, compared to a configuration in which information that can specify each background image is stored and held in advance, the consumption of the storage area associated with an increase in the type of background image is suppressed, and the game effects are diversified. The increase in the control burden accompanying the can be suppressed.

  (2) In the present embodiment, even when the seasonal change effect for changing (looping) from the winter image KY as the final stage of the seasonal change effect to the spring image KS as the initial stage is executed, the change parameter and the reference parameter By adding the additional parameter to the command value calculated from the above, it is possible to calculate the command value for specifying the background image after the change. Therefore, it is possible to suppress an increase in control burden accompanying diversification of game effects.

  (3) In this embodiment, a change parameter (first parameter) indicating a seasonal change and a change parameter (second parameter) indicating a place change are added (calculation) to the command value (reference parameter) of the current background image. By doing this, it is possible to calculate a command value that can specify the background image after the change in the background change effect. Therefore, in the present embodiment, compared to a configuration in which information that can individually specify the background image is stored and held in advance, it is possible to suppress the consumption amount of the storage area accompanying the increase in the type of the background image, and to suppress an increase in the control burden. .

  (4) In the present embodiment, when execution of a specific location change effect for changing to the background image HD1 that does not include the seasonal images KS, KH, KM, KY is determined, a command value that specifies the background image HD1 is determined in advance. The command value [900CH] is uniquely determined. Therefore, an appropriate command value can be determined even when a background image that does not include the seasonal images KS, KH, KM, and KY is separately prepared.

  (5) Furthermore, in this embodiment, even if it is a case where it is a case where it is going to change a background image by the change aspect different from the change aspect (rule) of the background image set to the seasonal change effect and the place change effect, There is no need to significantly change the processing content of the processing. Therefore, in this embodiment, the background image can be diversified more flexibly.

  (6) The overall control CPU 36a outputs a background image command for designating the current background image to the effect display control board 37 (display control CPU 37a) every time the symbol variation game is started. Whenever the background image command is input, the display control CPU 37a determines whether or not the command value of the input background image command matches the command value of the current background image. The display content of the image display unit GH is rewritten to a background image that can be specified by a command value specified by an image command. For this reason, in this embodiment, even if the type of the background image managed by the overall control CPU 36a does not match the type of the background image managed by the display control CPU 37a every time the symbol variation game is started. Can be matched early. Therefore, on the game effect between the display effect performed on the effect display device 22 (image display unit GH), the light effect performed on each of the lamp units 16a to 16c, and the sound effect performed on each of the speakers 17a to 17c. The occurrence of contradiction can be suppressed.

In addition, you may change the said embodiment as follows.
In the above embodiment, the background image is composed of the two background elements “seasonal image” serving as the first background element and “seasonal image” serving as the second background element, but the background image is composed of three or more background elements. May be configured. For example, a time image (morning, noon, night) may be added as the first background element, or a weather image (clear, cloudy, rain) may be added as the second background element. That is, a background image may be configured by using any one of the first background element and the second background element as a plurality, or a background image may be configured by using a plurality of both background elements.

  In the above embodiment, the background image is composed of the “seasonal image” as the first background element and the “location image” as the second background element. However, the above “time image” is used instead of the “seasonal image”. Alternatively, the “weather image” described above may be used instead of the “location image”.

  -In the said embodiment, you may change suitably the kind of image contained in a 1st, 2nd background element. For example, the seasonal image as the first background element may be two types, three types, or five or more types. Further, for example, the location image as the second background element may be two types or four or more types.

  In the above embodiment, the overall control CPU 36a is configured to output the background image command to the display control CPU 37a every time the symbol variation game is started. However, the symbol variation game is performed a predetermined number of times (for example, 2 times or 5 times). You may make it output whenever it is started. Even with this configuration, every time a predetermined number of symbol variation games are started, it is determined whether or not the background images managed by the overall control CPU 36a and the display control CPU 37a match and are managed by both CPUs. The types of background images to be matched can be matched.

  In the above embodiment, the overall control CPU 36a may be configured not to output the background image command when outputting the seasonal change command [9020H] and the place change commands [9030H] to [9033H]. The overall control CPU 36a may be configured not to always output the background image command. However, in order to eliminate the discrepancy between the types of background images managed by the overall control CPU 36a and the display control CPU 37a, it is more preferable that the overall control CPU 36a outputs a background image command as in the above embodiment.

  In the above embodiment, the overall control CPU 36a is configured to output a seasonal change command and a place change command, but a command value for specifying a background image after change in the background change effect calculated instead of each change command A background image command for designating may be output. In this case, the display control CPU 37a determines whether or not the command value of the input background image command matches the command value of the current background image, and the command value of the background image command input in the case of a mismatch. What is necessary is just to control the display content of the image display part GH so that the background change effect which changes to the identifiable background image may be performed. With this configuration, there is no need to calculate the command value of the background image after the change in the background change effect on the effect display control board 37 (display control CPU 37a) side, and the processing content of the display control CPU 37a is simplified. Can be

  In the above embodiment, the overall control CPU 36a may only output the seasonal change command and the place change command, and only the display control CPU 37a may calculate the command value of the background image after the change in the background change effect. . That is, it may be determined only whether or not the background change effect (seasonal change effect, place change effect) can be executed in the sub overall control board 36 (overall control CPU 36a). With this configuration, it is not necessary to calculate the command value of the background image after the change in the background change effect on the side of the sub overall control board 36 (overall control CPU 36a), and the processing content of the overall control CPU 36a is simplified. Can be

  In the above embodiment, the overall control CPU 36a and the display control CPU 37a are configured to calculate the command value of the background image after the change in the background change effect, but information that can specify the background image instead of the command value ( For example, a flag may be calculated. In this case, the command value of the background image command may be converted based on the information calculated by the overall control CPU 36a and output to the display control CPU 37a.

  In the above embodiment, the background image HD1 that does not include the seasonal images KS, KH, KM, and KY may be omitted, and the specific location change effect may not be executed. Two or more types of specific background images may be prepared as background images that do not include the seasonal images KS, KH, KM, and KY.

  In the above embodiment, when the seasonal change effect is further executed from the winter image KY at the final stage in the seasonal change effect, the additional parameter “−4” may not be added. In this case, it is possible to change to the background image including the spring image KS in the next background block. Even if comprised in this way, the change aspect of season image KS, KH, KM, KY can be made regular.

  In the above embodiment, when the seasonal change effect is further executed from the winter image KY at the final stage in the seasonal change effect, the additional parameter “−4” is added to the value of the reference parameter, and then the change parameter “1” is added. You may do it. In this case, the change parameter “1” may be added to the additional parameter “−4”, and the value after the addition may be added to the value of the reference parameter. Even with this configuration, the command value of the background image including the spring image KS at the initial stage can be calculated.

  In the above embodiment, the command values [9000H] to [900BH] for specifying the background image are configured so that the background image including the next seasonal image can be specified every time the command value increases by “1”. The next season image may be specified every time “2” increases or “5” increases. That is, it is only necessary to specify each background image in order according to a predetermined order as the order in which the seasonal image is changed from the initial stage to the final stage by using command values that are continuous at equal intervals. In this case, the change parameter indicating the place change is set to a value obtained by multiplying the step number of the seasonal change effect by the command value interval value, and to a value that is an integral multiple of the unit value. Good.

  In the above embodiment, the background block is configured by dividing the command values [9000H] to [900BH] continuous at equal intervals, but the interval between one background block and the next background block is “2” or more. It may be opened and separated. That is, the command value belonging to each background block may be a command value that continues at equal intervals, and the background image with different seasonal images may be specified by each command value. In this case, the change parameter as the second parameter indicating the location change is a background image belonging to a background block different from the background block to which the current background image belongs, and includes the same seasonal image as the current background image. What is necessary is just to set to the value changed to the background image made.

In the above embodiment, a hexadecimal value is used as a command value that can specify a background image. However, a binary value or a decimal value may be used.
In the above embodiment, one symbol variation game is configured to execute either a seasonal change effect or a place change effect, but both change effects are performed in one symbol variation game. You may comprise. In this case, if the change parameter set in the seasonal change command and the change parameter set in the place change command are added to the reference parameter value, a command value for specifying the background image after change is calculated. Good.

  In the above embodiment, one of the seasonal change effect and the place change effect is executed once in one symbol variation game. However, a plurality of seasonal change effects and locations are performed in one symbol variation game. You may make it perform change production.

In the above embodiment, the background image may include other background elements in addition to the “seasonal image” and the “location image”.
In the above embodiment, the sub integrated control board 36 may be omitted. In this case, the background process executed by the overall control CPU 36a may be executed by the main control board 35 (main control CPU 35a) or the effect display control board 37 (display control CPU 37a).

In the above embodiment, the effect display device 22 is configured as a liquid crystal display type, but may be a dot matrix type or a drum type effect display device 22 capable of projecting a background image.
In the above embodiment, a gaming machine that can execute a background change effect that changes the background image is embodied. However, instead of the background image, an information image that accompanies a symbol variation game such as a decorative symbol, an appearance character, and an effect mode is used. You may actualize to the game machine which can perform the information change effect to change. For example, in the case of a decorative design, the color of a numeric design is regularly changed as “blue” → “yellow” → “red” → “blue” →... As a result, the form of the number pattern is changed irregularly such as “Kanji numerals”, “Arabic numerals”, “Roman numerals”. Further, for example, in the case of an appearing character, the costume of the appearing character is regularly changed as “first suit” → “袴” → “clothes” → “suit” →. As the information element, the type of the appearance character may be irregularly changed such as “Character A”, “Character B”, and “Character C”. That is, the information is composed of a plurality of information elements, and the change parameter value corresponding to the change content of the information change determined by the overall control CPU 36a and the effect display device 22 are displayed as in the above embodiment. The command value for specifying the information after the change in the information change effect may be calculated based on the value of the reference parameter corresponding to the current information. Then, the display control CPU 37a controls the display content of the image display unit GH so as to execute an information change effect for changing to information that can be specified by the calculated command value. In this case, the overall control CPU 36a and the display control CPU 37a function as information calculation means. In addition, you may combine this another example (modified example) with the said other another example.
