(Structure of control register in VDP2000)
Here, the configuration of the control register 2010 provided in the VDP 2000 will be described with reference to FIG. FIG. 6 is a structural diagram obtained by obtaining representative data of the control register 2010 in the VDP2000.

  As described above, the control register 2010 includes six types of registers, that is, a system control register, a data transfer register, a drawing register, a bus interface register, an expansion register, and a display register. It is the structure figure which acquired and showed the typical data of the register, the expansion register, and the display register.

FIG. 6A is a structure diagram in which the 0th to 1st bits of the system control register are acquired. The 0th bit of the system control register is data instructing to output a V blank interrupt signal, and the 1st bit of the system control register is data instructing to output a drawing end interrupt signal. The 0th to 1st bits of these system control registers correspond to “interrupt registers”.
Specifically, the clock generation circuit 2050 generates a V blank interrupt signal (vertical synchronization signal) every 1/60 seconds (about 16.6 ms), and system control is performed every time the V blank interrupt signal is generated. 1 is set to 0 bit of the register. Further, when the drawing is completed, the drawing circuit 2070 sets 1 to the first bit of the system control register.
When 1 is set in these “interrupt registers”, the CPU I / F 2030 outputs a V blank interrupt signal or a drawing end interrupt signal to the host CPU 150a. The CPU I / F 2030 sets 0 to corresponding bits of various interrupt registers after outputting various interrupt signals.

FIG. 6B is a structure diagram in which the 0th bit of the drawing register is acquired. The 0th bit of the drawing register is data that instructs the drawing circuit 2070 to start drawing.
Specifically, the host CPU 150 a sets 1 to the 0 bit of the drawing register via the CPU I / F 2030 and instructs the drawing circuit 2070 to start drawing. When drawing starts, the drawing circuit 2070 sets 0 to the 0 bit of the drawing register.

FIG. 6C is a structure diagram in which the 0th to 1st bits of the decompression register are acquired. The 0th bit of the expansion register is data instructing the expansion circuit 2060 to start expansion of the compressed image. The first bit of the decompression register is data indicating the decompression execution state of the decompression circuit 2060.
Specifically, the drawing circuit 2070 analyzes the display list output from the host CPU 150a. If the image data to be used does not exist in the expanded storage area 153b of the VRAM 153, the drawing circuit 2070 sets 1 to the 0 bit of the expansion register, The decompression circuit 2060 is instructed to start decompressing image data to be used and store it in the expanded storage area 153b. When the decompression circuit 2060 starts decompression, it sets 0 to the 0 bit of the decompression register.
The decompression circuit 2060 sets 1 to the 1-bit of the decompression register while decompression is being performed, and sets 0 to the 1-bit of the decompression register when the decompression of the compressed image is completed.

FIG. 6D is a structure diagram in which the 0th to 1st bits of the display register are acquired. The 0 bit of the display register is data for instructing the display circuit 2080 to output a video signal, and the 1 bit of the display register is data for specifying the frame buffer of the VRAM 153.
Specifically, the host CPU 150a instructs the display circuit 2080 to create and output a video signal by setting 1 to the 0 bit of the display register via the CPU I / F 2030 when the power is turned on. As a result, the display circuit 2080 generates a video signal based on the designated image data in the “display frame buffer” and outputs the video signal to the liquid crystal display device 31.
If the drawing is finished when the V blank interrupt signal is input, the host CPU 150a adds 1 to the first bit of the display register via the CPU I / F 2030, and displays “display” on the memory controller 2090. An instruction to switch between “frame buffer” and “drawing frame buffer” is given. That is, every time drawing ends, 1 is added to the 1st bit of the display register, so that “0 → 1 → 0 → 1 →...” Is switched.

  The structure diagram of the register shown in FIG. 6 is merely obtained from representative data of the control register 2010, and it goes without saying that more detailed data exists.

  Next, details of various tables stored in the main ROM 110b will be described with reference to FIGS.

(Big hit judgment table)
FIG. 7 (a-1) and FIG. 7 (a-2) are diagrams showing a jackpot determination table used for the “big winning lottery”. FIG. 7 (a-1) is a jackpot determination table referred to in the first special symbol display device 20, and FIG. 7 (a-2) is a jackpot determination table referred to in the second special symbol display device 21. is there. In the tables of FIG. 7A-1 and FIG. 7A-2, although the winning probabilities for small hits are different, the jackpot probabilities are the same.

Specifically, the big hit determination table is used to determine whether “big hit”, “small hit”, or “losing” based on the current probability gaming state and the acquired random number for determining a special symbol.
For example, according to the jackpot determination table for the first special symbol display device shown in FIG. 7 (a-1), the two special symbol determination disturbances “7” and “8” are in the low probability gaming state. The number is determined to be a big hit. On the other hand, in the high probability gaming state, 20 special symbol determination random numbers “7” to “26” are determined to be big hits.
Further, according to the jackpot determination table for the first special symbol display device shown in FIG. 7 (a-1), the random number value for special symbol determination is obtained in the low probability gaming state or the high probability gaming state. In the case of four special symbol determination random numbers “50”, “100”, “150”, and “200”, it is determined as “small hit”. If the random number is other than the above, it is determined as “lost”.
Therefore, since the random number range of the special symbol determination random number value is 0 to 598, the probability of being determined to be a big hit in the low probability gaming state is 1 / 299.5, and in the high probability gaming state, The probability to be determined is 10 times up to 1 / 29.9. In the first special symbol display device, the probability of being determined to be a small hit is 1 / 149.75 regardless of whether the game state is a low probability game state or a high probability game state.

(Winning judgment table)
FIG. 7B is a diagram showing a hit determination table used for “normal symbol lottery”.
Specifically, the winning determination table determines whether it is “winning” or “lost” based on the presence / absence of the short-time gaming state and the acquired random number for normal symbol determination.
For example, according to the hit determination table shown in FIG. 7B, when in the non-time-saving gaming state, it is determined that one specific normal symbol determination random value of “0” is a win. On the other hand, when in the short-time gaming state, it is determined that 65535 specific random symbols for determining normal symbols from “0” to “65534” are hit. If the random number is other than the above, it is determined as “lost”.
Therefore, since the random number range of the normal symbol determination random number value is 0 to 65535, the probability of being determined to be hit in the non-short-time gaming state is 1/65536, and the probability of being determined to be winning in the time-short gaming state is 65535/65536 = 1 / 1.00002.

(Design determination table)
FIG. 8 is a diagram showing a symbol determination table for determining a special symbol stop symbol.
FIG. 8A is a symbol determination table that is referred to in order to determine a stop symbol at the time of a big hit, and FIG. 8B is a symbol that is referred to in order to determine a stop symbol at the time of a big hit. FIG. 8C is a symbol determination table that is referred to in order to determine a stop symbol in the event of a loss.

Specifically, according to the symbol determination table shown in FIG. 8, the type of special symbol display device (the type of the start opening in which the game ball has won) and the game ball in the first start port 14 or the second start port 15 The special symbol type (stop symbol data) is determined based on the jackpot symbol random number value or the small bonus symbol random number value acquired when the ball is entered.
For example, the first special symbol display device refers to the symbol determination table shown in FIG. 8A in the case of a jackpot, and if the acquired jackpot symbol random number value is “55”, the stop symbol data is “03”. ”(Special symbol 3 (first positive variation jackpot 3)) is determined. Further, in the first special symbol display device, the symbol determination table shown in FIG. 8B is referred to at the time of small hitting, and if the acquired random number for small hitting symbol is “50”, as the stopped symbol data “08” (special symbol B (small hit B)) is determined. In the case of a loss, “00” (special symbol 0 (lost)) is determined as stop symbol data without referring to any random value.

  Then, at the time of starting the change of the special symbol, an effect designating command is generated as special symbol information based on the determined special symbol type (stop symbol data). Here, the effect designating command is composed of 2-byte data, and 1-byte MODE data for identifying the control command classification and 1-byte DATA indicating the contents of the control command to be executed. It consists of data. The same applies to a variation pattern designation command described later.

  The game state after jackpot game and the type of jackpot game are determined by the type of special symbol (stop symbol data), so the type of special symbol determines the game state after jackpot game and the type of jackpot game. It can be said that it is determined.

(Description of gaming state)
Next, the gaming state when the game progresses will be described. In this embodiment, there are “low probability gaming state” and “high probability gaming state” as the states related to the jackpot lottery, and “non-short-time gaming state” is the state relating to the pair of movable pieces 15b that the second starting port 15 has. And “short-time gaming state”. The state relating to the jackpot lottery (low probability gaming state, high probability gaming state) and the state relating to the pair of movable pieces 15b (non-short-time gaming state, short-time gaming state) can be associated with each other and are independent. You can also. In other words,
(1) “Low probability gaming state” and “Time saving gaming state”
(2) “Low probability gaming state” and “non-temporary gaming state”
(3) “High probability gaming state” and “short time gaming state”
(4) It is possible to provide a “high probability gaming state” and a “non-temporary gaming state”.
Note that the gaming state when the game is started, that is, the initial gaming state of the gaming machine 1 is a “low probability gaming state” and is set to a “non-short-time gaming state”. Is referred to as a “normal gaming state”.

In the present embodiment, the “low probability gaming state” means that in the jackpot lottery performed on the condition that a game ball has entered the first starting port 14 or the second starting port 15, the winning probability of the jackpot is 1 / The game state set to 299.5. On the other hand, the “high probability gaming state” means a gaming state in which the jackpot winning probability is set to 1 / 29.95. Therefore, in the “high probability gaming state”, it is easier to win a jackpot than in the “low probability gaming state”. Note that a high-probability game flag, which will be described later, is set in this high-probability game state, and the high-probability game flag is off in the low-probability game state.
Further, the low probability gaming state is changed to the high probability gaming state after the jackpot game described later is finished.

  In the present embodiment, the “non-short game state” means that, in the normal symbol lottery performed on the condition that the game ball has passed through the normal symbol gate 13, the variation time of the normal symbol corresponding to the lottery result is 29 seconds. And a game state in which the opening control time of the second start port 15 is set to be as short as 0.2 seconds. That is, when the game ball passes through the normal symbol gate 13, the normal symbol is drawn, and the normal symbol display device 22 displays the fluctuation of the normal symbol, but the normal symbol is displayed 29 seconds after the fluctuation display is started. Stop display later. If the lottery result is a win, the second start port 15 is controlled to the second mode for about 0.2 seconds after the normal symbol stop display.

On the other hand, the “short-time gaming state” means that the normal symbol variation time corresponding to the lottery result is 3 seconds in the normal symbol lottery performed on condition that the game ball has passed through the normal symbol gate 13. , A game that is set shorter than the “non-short game state”, and the opening control time of the second start port 15 when winning in the win is 3.5 seconds, which is set longer than the “non-short game state” State. Furthermore, in the “non-short-time gaming state”, the probability of winning in the normal symbol lottery is set to 1/65536, and in the “short-time gaming state”, the probability of winning in the normal symbol lottery is set to 65535/65536. Is set. At this time, the short-time game flag, which will be described later, is set in the short-time game state, and the short-time game flag is off in the non-short-time game state.
Therefore, in the “short-time gaming state”, the second starting port 15 is more easily controlled to the second mode as long as the game ball passes through the normal symbol gate 13 than in the “non-short-time gaming state”. Thereby, in the “short-time gaming state”, the player can advance the game without consuming the game ball.
In addition, since the normal symbol gate 13 is provided in the area on the right side of the game area 6, in the “short-time game state”, the operation handle 3 is greatly rotated, and the game ball is launched with a strong launch strength. Is configured to do.
Note that the probability of winning in the normal symbol lottery may be set so that it does not change in any of the “non-short-time gaming state” and the “time-short gaming state”.

(Description of types of jackpot games)
In the present embodiment, a “long winning game” in which the first big winning opening 16 is opened with a long opening time, a “short winning game” in which the second big winning opening 17 is opened in a short opening time, and a second big winning prize. There are provided three types of “big hit games” and one type of “small hit games” in which the mouth 17 is opened with a short opening time and then opened with a long opening time. In the present embodiment, the “big hit game” and the “small hit game” are collectively referred to as “special game”.

In the present embodiment, “long win game” means that a big win is won and a long jackpot is won in a big win lottery performed on condition that a game ball has entered the first start port 14 or the second start port 15. A game that is executed when the corresponding special symbol is determined.
In the “long game”, a round game in which the first grand prize winning opening 16 is opened is performed 15 times in total. The maximum opening time of the first grand prize opening 16 in each round game is set to a maximum of 29 seconds. Round game is over. In other words, “game per long” is a special game in which a game ball enters the first grand prize opening 16 and a player can acquire a prize ball according to the game, so that a lot of prize balls can be acquired. It is. In addition, since the first grand prize winning opening 16 is provided in the area on the right side of the game area 6, in the case of “long hit game”, the operation handle 3 is greatly rotated to launch the game ball with a strong launch intensity. And is configured to play a game.

In the present embodiment, “short win game” means that, in the big win lottery performed on the condition that a game ball has entered the first start port 14 or the second start port 15, A game that is executed when the corresponding special symbol is determined.
In the “short win game”, a round game in which the second grand prize winning opening 17 is opened is performed 15 times in total. The maximum opening time of the second grand prize opening 17 in each round game is set to a maximum of 0.052 seconds, which is shorter than the firing time (about 0.6 seconds) at which one game ball is launched. Yes. During this time, if a specified number (9) of game balls enter the second grand prize opening 17, one round game is completed, but the opening time of the second big prize opening 17 is extremely short as described above. , Game balls rarely enter. In other words, the “short win game” is a special game in which it is difficult to obtain a prize ball unlike the “long win game”.

In the present embodiment, “game per development” means winning in the jackpot lottery performed on condition that a game ball has entered the first start port 14 or the second start port 15, A game that is executed when the corresponding special symbol is determined.
In "game per development", a round game in which the second grand prize winning opening 17 is opened is performed a total of 15 times. In the first round game, after performing an opening / closing operation with a short opening time of the second big prize opening 17 a plurality of times, an opening / closing operation with a long opening time of the second big prize opening 17 is performed. The maximum opening time of the second grand prize opening 17 after two rounds of game is set to 29 seconds, and if a predetermined number of game balls (for example, nine) enter the second big prize opening 17 during this time, one time The round game ends. In other words, “game per development” initially repeats an opening / closing operation with a short opening time of the second big prize opening 17 and then repeating an opening / closing operation with a long opening time of the second big prize opening 17, This is a game in which a large number of prize balls can be obtained because a game ball enters the second big prize opening 17 and a player can obtain a prize ball according to the prize.

In the present embodiment, “small hit game” means the right to execute a small hit game in the jackpot lottery performed on condition that a game ball has entered the first start port 14 or the second start port 15. A game that is executed when the player wins the game.
Also in the “small win game”, the second big prize opening 17 is opened 15 times as in the “short win game”. At this time, the opening time, opening / closing timing, and opening / closing mode of the second big prize opening 17 are the same as the above “short win game”, or the player determines whether the “small win game” or “short win game” It is set to approximate the impossible or difficult level.

  Next, the progress of the game in the gaming machine 1 will be described using a flowchart.

(Main processing of main control board)
The main process of the main control board 110 will be described with reference to FIG.

  When power is supplied from the power supply board 170, a system reset occurs in the main CPU 110a, and the main CPU 110a performs the following main processing.

  First, in step S10, the main CPU 110a performs an initialization process. In this process, the main CPU 110a reads a startup program from the main ROM 110b and initializes a flag stored in the main RAM 110c in response to power-on.

  In step S20, the main CPU 110a performs an effect random number update process for updating the reach determination random value and the special figure variation random value for determining the variation mode (variation time) of the special symbol.

  In step S30, the main CPU 110a updates the initial random number value for special symbol determination, the initial random number value for big hit symbol, the initial random number value for small bonus symbol, and the initial random number value for normal symbol determination. Thereafter, the processes of step S20 and step S30 are repeated until a predetermined interrupt process is performed.

(Timer interrupt processing of main control board)
The timer interrupt process of the main control board 110 will be described with reference to FIG.

  A clock pulse is generated every predetermined period (4 milliseconds) by the reset clock pulse generation circuit provided on the main control board 110, thereby executing a timer interrupt process described below.

  First, in step S100, the main CPU 110a saves the information stored in the register of the main CPU 110a to the stack area.

  In step S110, the main CPU 110a updates the special symbol time counter, updates the special game timer counter such as the opening time of the special electric accessory, updates the normal symbol time counter, and updates the normal power release time counter. A time control process for updating various timer counters is performed. Specifically, a process of subtracting 1 from a special symbol time counter, a special game timer counter, a normal symbol time counter, and a general electricity open time counter is performed.

In step S120, the main CPU 110a performs a random number update process for the special symbol determination random number value, the big hit symbol random number value, the small hit symbol random number value, and the normal symbol determination random number value.
Specifically, each random number value and random number counter are updated by adding +1. When the added random number counter exceeds the maximum value in the random number range (when the random number counter makes one revolution), the random number counter is returned to 0, and each random number value is newly updated from the initial random number value at that time. .

  In step S130, as in step S30, the main CPU 110a updates the initial random number value for special symbol determination, the initial random number value for big hit symbol, the initial random number value for small hit symbol, and the initial random number value for normal symbol determination. Perform numerical value update processing.

In step S200, the main CPU 110a performs input control processing.
In this process, the main CPU 110a includes a general winning opening detection switch 12a, a first large winning opening detection switch 16a, a second large winning opening detection switch 17a, a first starting opening detection switch 14a, a second starting opening detection switch 15a, a gate. An input process for determining whether or not there is an input to each switch of the detection switch 13a is performed.

  Specifically, various detection signals from the general winning opening detecting switch 12a, the first big winning opening detecting switch 16a, the second large winning opening detecting switch 17a, the first starting opening detecting switch 14a, and the second starting opening detecting switch 15a. Is inputted, predetermined data is added to the prize ball counter used for the prize ball provided for each prize opening and updated.

  Furthermore, when a detection signal is input from the first start port detection switch 14a, if the data set in the first special symbol hold number (U1) storage area is less than 4, the first special symbol hold number ( U1) Add 1 to the storage area to obtain special symbol determination random number value, jackpot symbol random number value, small hit symbol random number value, reach determination random value, and special symbol variation random value The random number value is stored in a predetermined storage unit (0th storage unit to 4th storage unit) in the first special symbol random value storage area.

Similarly, when a detection signal is input from the second start port detection switch 15a, if the data set in the second special symbol hold number (U2) storage area is less than 4, the second special symbol hold number (U2) 1 is added to the storage area, and a special symbol determination random number value, a big hit symbol random number value, a small hit symbol random number value, a reach determination random number value, and a special symbol variation random value are acquired. Various random numbers are stored in a predetermined storage unit (0th storage unit to 4th storage unit) in the second special symbol random number value storage area.
In the present embodiment, the main CPU 110a that performs input control processing when the detection signal from the first start port detection switch 14a or the second start port detection switch 15a in step S200 is input constitutes the determination information acquisition unit. In the present embodiment, the special symbol determination random number value constitutes the special determination information, the jackpot symbol random number value constitutes the specific determination information, and the reach determination random number value constitutes the effect determination information.

  When a detection signal is input from the gate detection switch 13a, if the data set in the normal symbol hold number (G) storage area is less than 4, the normal symbol hold number (G) storage area is set to 1. It adds, acquires the random number value for normal symbol determination, and memorize | stores the acquired random number value for normal symbol determination in the predetermined memory | storage part (0th memory | storage part-4th memory | storage part) in a normal symbol holding | maintenance storage area.

  Further, when a detection signal is input from the first grand prize opening detection switch 16a or the second big prize opening detection switch 17a, the number of game balls won in the first big prize opening 16 or the second big prize opening 17 is counted. 1 is added to the number of entries (C) storage area for the big winning opening to update.

  In step S300, the main CPU 110a performs a special drawing special electric control process for controlling the jackpot lottery, the special electric accessory, and the gaming state. Details will be described later with reference to FIG.

In step S400, the main CPU 110a performs a normal / normal power control process for controlling the normal symbol lottery and the normal electric accessory.
Specifically, it is first determined whether or not one or more data is set in the normal symbol hold count (G) storage area, and one or more data must be set in the normal symbol hold count (G) storage area. If this is the case, the current ordinary power transmission control process is terminated.
If 1 or more data is set in the normal symbol holding number (G) storage area, after subtracting 1 from the value stored in the normal symbol holding number (G) storage area, the data is in the normal symbol holding storage area. The normal symbol determination random numbers stored in the first storage unit to the fourth storage unit are shifted to the previous storage unit. At this time, the normal symbol determination random value already written in the 0th storage unit is overwritten and erased.
Then, referring to the hit determination table shown in FIG. 7B, whether or not the normal symbol determination random number value stored in the 0th storage unit of the normal symbol hold storage area is a random value corresponding to “win”. Processing to determine is performed. Thereafter, the normal symbol display device 22 displays the fluctuation of the normal symbol. When the fluctuation time of the normal symbol elapses, the normal symbol corresponding to the result of the normal symbol lottery is stopped and displayed. If the random number for normal symbol determination referred to is “winning”, the start opening / closing solenoid 15c is driven to control the second start opening 15 to the second mode for a predetermined opening time.
Here, in the non-short-time gaming state, the variation time of the normal symbol is set to 29 seconds, and if it is “winning”, the second start port 15 is controlled to the second mode for 0.2 seconds. On the other hand, in the short-time gaming state, the normal symbol variation time is set to 0.2 seconds, and if it is “winning”, the second start port 15 is controlled to the second mode for 3.5 seconds. .

In step S500, the main CPU 110a performs a payout control process.
In this payout control process, the main CPU 110a refers to each prize ball counter, generates payout number designation commands corresponding to various winning ports, and transmits the generated payout number designation commands to the payout control board 130. To do.

In step S700, the main CPU 110a performs output control processing. In this process, a port output process is performed for outputting signals of the external information data, the start opening / closing solenoid data, the first big prize opening / closing solenoid data, and the second big prize opening / closing solenoid data created in S600.
Further, the special symbol display device data and the normal symbol display device data created in S600 are used to turn on the LEDs of the first special symbol display device 20, the second special symbol display device 21 and the normal symbol display device 22. Display device output processing is performed.
Further, command transmission processing for transmitting the command set in the effect transmission data storage area of the main RAM 110c to the effect control board 120 is also performed. The types of commands transmitted to the effect control board 120 will be described later with reference to FIG.

  In step S800, the main CPU 110a restores the information saved in step S100 to the register of the main CPU 110a.

(Special figure special electric control processing of main control board)
With reference to FIG. 11, the special figure special power control process of the main control board 110 will be described.

First, in step S301, the value of the special figure special electricity processing data is loaded, the branch address is referred to from the special figure special electric treatment data loaded in step S302, and if the special figure special electric treatment data = 0, the special symbol memory determination process (step The process proceeds to S310). If the special symbol special power processing data = 1, the process proceeds to the special symbol variation processing (step S320). If the special symbol special power processing data = 2, the special symbol stop processing (step S330) is performed. If special figure special electric processing data = 3, the process moves to jackpot game processing (step S340), and if special figure special electric processing data = 4, the process moves to big hit game end processing (step S350). If special electric processing data = 5, the process moves to the small hit game ending process (step S360).
This “special drawing special electricity processing data” is set as necessary in each subroutine of the special figure special electricity control processing as will be described later, so that the subroutine necessary for the game is appropriately processed. .

  In the special symbol memory determination process in step S310, the main CPU 110a performs a jackpot determination process, a special symbol determination process for determining a special symbol to be stopped and displayed, a variation time determination process for determining a variation time of the special symbol, and the like. Here, the specific content of the special symbol memory determination process will be described with reference to FIG.

(Special symbol memory judgment processing of the main control board)
FIG. 12 is a diagram showing a special symbol memory determination process of the main control board 110.

First, in step S311, the main CPU 110a determines whether one or more data is set in the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area.
If one or more data is not set in any storage area of the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area, the special figure special electricity processing data = 0. The special symbol variation process of this time is terminated while holding.
On the other hand, if one or more data is set in the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area, the process proceeds to step S312.

In step S312, the main CPU 110a performs a jackpot determination process.
Specifically, when one or more data is set in the second special symbol hold count (U2) storage area, 1 is calculated from the value stored in the second special symbol hold count (U2) storage area. After the subtraction, the various random numbers stored in the first to fourth storage units in the second special symbol random number storage area are shifted to the previous storage unit. At this time, various random values already written in the 0th storage unit are overwritten and deleted. Then, with reference to the jackpot determination table shown in FIG. 7 (a-2), the random number for special symbol determination stored in the 0th storage unit of the second special symbol random number storage area corresponds to “big hit”. It is determined whether it is a numerical value or a random value corresponding to “small hit”.
In addition, when one or more data is not set in the second special symbol hold number (U2) storage area and one or more data is set in the first special symbol hold number (U1) storage area, Various random numbers stored in the first to fourth storage units in the first special symbol random number storage area after subtracting 1 from the value stored in the first special symbol hold number (U1) storage area Is shifted to the previous storage unit. Also at this time, various random numbers already written in the 0th storage section are overwritten and deleted. Then, with reference to the jackpot determination table shown in FIG. 7 (a-1), the random number value for special symbol determination stored in the 0th storage unit of the first special symbol random number storage area corresponds to “big hit”. It is determined whether it is a numerical value or a random value corresponding to “small hit”.
In the present embodiment, the random number value stored in the second special symbol random value storage area is shifted (digested) with priority over the first special symbol random value storage area. However, the first special symbol storage area or the second special symbol storage area may be shifted in the order of winning in the starting opening, and the first special symbol storage area is given priority over the second special symbol storage area. You may let them.

In step S313, the main CPU 110a performs a special symbol determination process for determining the type of special symbol to be stopped and displayed.
In this special symbol determination process, when it is determined as “big hit” in the jackpot determination process (step S312), the first special symbol random value storage area is referred to with reference to the symbol determination table shown in FIG. The jackpot symbol (special symbol 1 to special symbol 6) is determined based on the random number value for the jackpot symbol stored in the 0th storage unit. In addition, when it is determined as “small hit” in the big hit determination process (step S312), the 0th memory of the first special symbol random value storage area is referred to with reference to the symbol determination table shown in FIG. 8B. The small hit symbol (special symbol A, special symbol B) is determined based on the random number value for the small bonus symbol stored in the section. If it is determined that the game has been determined to be “lost” in the jackpot determination process (step S312), the lost symbol (special symbol 0) is determined with reference to the symbol determination table shown in FIG.
Then, stop symbol data corresponding to the determined special symbol is stored in the stop symbol data storage area.

In step S314, the main CPU 110a performs special symbol variation time determination processing.
Specifically, the variation pattern of the special symbol is determined based on the reach determination random number value and the special diagram variation random value stored in the 0th storage unit of the first special symbol random value storage area. Thereafter, the variation time of the special symbol corresponding to the determined variation pattern of the special symbol is determined. Then, a process of setting a counter corresponding to the determined variation time of the special symbol in the special symbol time counter is performed.

In step S315, the main CPU 110a sets, in a predetermined processing area, variation display data for causing the first special symbol display device 20 or the second special symbol display device 21 to perform special symbol variation display (LED blinking). . As a result, when the variable display data is set in the predetermined processing area, the LED lighting / extinguishing data is appropriately created in step S600, and the created data is output in step S700. Variation display of the special symbol display device 20 or the second special symbol display device 21 is performed.
Further, the main CPU 110a, when the special symbol variation display is started, the special symbol variation pattern designation command (the first special symbol variation pattern designation command) corresponding to the special symbol variation pattern determined in step S314. Alternatively, the second special symbol variation pattern designation command) is set in the effect transmission data storage area of the main RAM 110c.

In step S316, the main CPU 110a sets the special symbol special electricity processing data = 0 to the special symbol special electric treatment data = 1, prepares to move to the special symbol variation processing subroutine, and ends the special symbol memory determination processing.
In the present embodiment, the main CPU 110a that performs jackpot determination processing constitutes special game determination means.

The description of the special figure special electric control process shown in FIG. 11 will be returned.
In the special symbol variation process of step S320, the main CPU 110a performs a process of determining whether or not the special symbol variation time has elapsed.
Specifically, it is determined whether or not the variation time of the special symbol determined in step S314 has elapsed (special symbol time counter = 0), and if it is determined that the variation time of the special symbol has not elapsed The special symbol variation process is terminated while the special symbol special electricity processing data = 1 is held. Note that the special symbol variation time counter set in step S314 is subtracted in step S110.
If it is determined that the variation time of the special symbol has elapsed, the special symbol determined in step S313 is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21. Thereby, the special symbol is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21, and the player is notified of the jackpot determination result.
Also, when the number of time reduction (J)> 0, 1 is subtracted from the time reduction (J) counter and updated. When the number of time reduction (J) = 0, the time reduction game flag is cleared and the number of high probability games (X )> 0 is updated by subtracting 1 from the high probability game number (X) counter, and if the high probability game number (X) = 0, the high probability game flag is cleared.
Finally, the special symbol special power processing data = 1 is set to the special symbol special power processing data = 2, preparation is made to move to a special symbol stop processing subroutine, and the special symbol variation processing is terminated.

In the special symbol stop process in step S330, the main CPU 110a performs a process of determining whether the special symbol that is stopped and displayed is a “big hit symbol”, a “small bonus symbol”, or a “losing symbol”. Do.
If it is determined that the game is a jackpot symbol, the data stored in the gaming state storage area is referred to and data (00H to 03H) indicating the current gaming state is set in the gaming state buffer. Thereafter, the data (high probability game flag and short time game flag), high probability game number (X) counter, and short time number (J) counter stored in the high probability game flag storage area and the short time game flag storage area are cleared. . Further, the special figure special power processing data = 2 is set to the special figure special electric processing data = 3, preparation is made to move to the jackpot game processing subroutine, and the special symbol stop processing is ended.
In addition, when it is determined that the small winning symbol, the data stored in the game state storage area is not cleared, and the special figure special electric processing data = 2 to the special figure special electric treatment data = 5 is set. The special symbol stop process is completed by making preparations for transferring to a winning game process subroutine.
On the other hand, if it is determined that the symbol is a lost symbol, the special symbol special electric processing data = 2 is set to special special electric symbol processing data = 0, and the special symbol memory determination processing subroutine is prepared for the special symbol stop processing. finish.

In the jackpot game process of step S340, the main CPU 110a determines which jackpot of the long hit or short hit is executed, and performs a process of controlling the determined jackpot.
Specifically, based on the type of jackpot symbol (stop symbol data) determined in step S313, the jackpot release mode is determined (TBL per long, TBL per short, or TBL per development is determined).
Next, in order to execute the determined jackpot release mode, an opening time corresponding to the type of jackpot is set in the special game timer counter, and the first big prize opening / closing solenoid 16c (or the second big prize opening / closing solenoid 17c is used). ) Driving data is output to open the first big prize opening / closing door 16b (or the second big prize opening / closing door 17b). At this time, 1 is added to the round game count (R) storage area.
When a predetermined number of game balls enter during the opening or when the opening time of the big prize opening has elapsed (the number of the big prize opening (C) = 9 or the special game timer counter = 0), The output of the drive data of the big prize opening / closing solenoid 16c (or the second big prize opening / closing solenoid 17c) is stopped, and the first big prize opening / closing door 16b (or the second big prize opening / closing door 17b) is closed. Thereby, one round game is completed. This round game control is repeated 15 times.
When the 15 round games are completed (round game count (R) = 15), the data stored in the round game count (R) storage area and the number of winning prize entrance (C) storage areas are cleared, The special figure special electric processing data = 3 is set to the special figure special electric treatment data = 4, preparation is made to move to the big hit game end processing subroutine, and the big hit game processing is ended.
In the present embodiment, the main CPU 110a that performs the jackpot game process shown in step S340 constitutes a special game control means.

In the big hit game ending process in step S350, the main CPU 110a determines either the high probability game state or the low probability game state, and the game state of either the short-time game state or the non-short-time game state. Perform the decision process.
Specifically, based on the data stored in the game state buffer and the type of jackpot symbol (stop symbol data) determined in step S313, the setting of the high probability game flag, the number of high probability games (X) , Time-short game flag, time-short number of times (J). For example, in the case of the special symbol 1, the high probability game flag is set in the high probability game flag storage area, and the high probability game number (X) counter is set to 10,000 times. Further, a time-short game flag is set in the time-short game flag storage area, and a time-short time (J) counter is set to 10,000 times.
After that, the special symbol special power processing data = 4 is set to the special symbol special power processing data = 0, and preparation for moving to the special symbol memory determination processing subroutine is made, and the big hit game end processing is ended.
In the present embodiment, the main CPU 110a that performs the jackpot game end process shown in step S350 for determining the game state constitutes the game state determination means.
In the present embodiment, the first jackpot and the short-time gaming state that the first big winning opening 16 opens constitute the specific gaming state, and the main CPU 110a that performs the special figure special electric control processing constitutes the gaming state control means.

In the small hit game processing in step S360, the main CPU 110a determines the small hit release mode based on the type of small hit symbol (stop symbol data) determined in step S313.
Next, in order to execute the determined small winning opening mode, the small winning opening time is set in the special game timer counter, and the driving data of the second large winning opening / closing solenoid 17c is output to output the second large winning opening. The open / close door 17b is opened. At this time, 1 is added to the number-of-releases (K) storage area.
When the small winning opening time elapses (special game timer counter = 0), the drive data output of the second big prize opening / closing solenoid 17c is stopped and the second big prize opening / closing door 17b is closed. The opening / closing control of the second big prize opening opening / closing door 17b is repeated 15 times.
Then, the opening / closing control of the second grand prize opening / closing door 17b is performed 15 times, or a predetermined number of game balls enter the second big prize opening 17 (the number of times of opening (K) = 15 or the grand prize opening entrance) Number (C) = 9), in order to end the small hit game, the output of the drive data of the second large winning opening / closing solenoid 17c is stopped, the number of times of opening (K) storage area and the number of winning winning holes (C) Clear the data stored in the storage area, set special figure special electricity processing data = 5 to special figure special electricity treatment data = 0, and prepare to move to a special symbol memory judgment processing subroutine.

(Command explanation)
The types of commands transmitted from the main control board 110 to which the description is partially omitted in the flowchart of the main control board 110 to the effect control board 120 will be described with reference to FIG.

  The command transmitted from the main control board 110 to the production control board 120 is composed of 1-byte data, and 1-byte MODE information for identifying the control command classification and the control command to be executed. And 1-byte DATA information indicating the contents of.

The “designation designating command” indicates the type of the special symbol that is stopped and displayed, “MODE” is set as “E0H”, and DATA information is set according to the type of the special symbol. Since the special symbol type determines the jackpot type and the high probability gaming state as a result, it can be said that the effect symbol designation command indicates the jackpot type and the gaming state.
In the effect symbol designation command, when various special symbols are determined and the variation display of the special symbol is started, an effect symbol designation command corresponding to the determined special symbol is transmitted to the effect control board 120. Specifically, when various special symbols are determined in step S313, and the special symbol variation display is started in step S315, the effect symbol designation command corresponding to the determined special symbol is the effect of the main RAM 110c. Set in the transmission data storage area. Thereafter, the effect designating command set in the effect transmission data storage area in step S700 is immediately transmitted to the effect control board 120.

The “first special symbol memory designation command” indicates the number of reserved memories stored in the first special symbol reservation number (U1) storage area, “MODE” is set to “E1H”, and the number of reserved memories DATA information is set according to the above.
This first special symbol memory designation command is effect-controlled by the first special symbol memory designation command corresponding to the number of reserved memories when the number of reserved memories stored in the first special symbol reservation number (U1) storage area is switched. It is transmitted to the substrate 120. Specifically, when the value stored in the first special symbol hold count (U1) storage area in S200 or step S312 increases or decreases, the first special symbol storage designation corresponding to the increased or decreased hold memory count The command is set in the effect transmission data storage area of the main RAM 110c. Thereafter, the first special symbol memory designation command set in the production transmission data storage area in step S700 is immediately transmitted to the production control board 120.

The “second special symbol memory designation command” indicates the number of reserved memories stored in the second special symbol reservation number (U2) storage area, “MODE” is set to “E2H”, and the number of reserved memories DATA information is set according to the above.
This second special symbol memory designation command is directed by the second special symbol memory designation command corresponding to the number of reserved memories when the number of reserved memories stored in the second special symbol reservation number (U2) storage area is switched. It is transmitted to the substrate 120. Specifically, when the value stored in the second special symbol hold count (U2) storage area in S200 or step S312 increases or decreases, the second special symbol storage designation corresponding to the increased or decreased hold memory count The command is set in the effect transmission data storage area of the main RAM 110c. Thereafter, the second special symbol memory designation command set in the production transmission data storage area in step S700 is immediately transmitted to the production control board 120.
In the present embodiment, the “first special symbol memory designation command” and the “second special symbol memory designation command” are collectively referred to as “special symbol memory designation command”.

The “design determination command” indicates that the special symbol is stopped and displayed, “MODE” is set to “E3H”, and “DATA” is set to “00H”.
This symbol confirmation command is transmitted to the effect control board 120 when the special symbol is stopped and displayed. Specifically, when the special symbol is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21 in step S320, the symbol confirmation command is set in the effect transmission data storage area of the main RAM 110c.

  Next, processing executed by the host CPU 150a in the image control board 150 will be described.

(Main processing of image control board)
The main process of the image control board 150 will be described with reference to FIG.
When power is supplied from the power supply board 170, a system reset occurs in the host CPU 150a, and the host CPU 150a performs the following main processing.

In step S2010, the host CPU 150a performs an initialization process. In this processing, the host CPU 150a reads the main processing program from the host ROM 150c and instructs the initial settings of the various modules of the host CPU 150a and the VDP 2000 when the power is turned on.
Here, the host CPU 150a uses the VDP2000 initial setting instruction as follows:
(1) To instruct the display circuit 2080 to create and output a video signal, instruct the video signal to be created (set 1 to 0 bit of the display register),
(2) In order to cause the decompression circuit 2060 to decompress the image data (image data such as the production symbol 36) frequently used in the decompression storage area 153b of the VRAM 153, set predetermined initial value data in the decompression register. ,
(3) In order to cause the drawing circuit 2070 to draw initial value image data (such as a character image “power-on”), an initial value display list is output.

In step S2020, the host CPU 150a performs a drawing execution start process. In this process, in order to instruct the VDP 2000 to execute drawing on the display list that has already been output, drawing start data is set in the drawing register (see FIG. 6B).
That is, at the start of power-on, execution of drawing for the initial value display list output in step S2010 is instructed, and during normal routine processing, execution of drawing for the display list output in S2050 described later is instructed. .

In step S2030, the host CPU 150a performs effect instruction command analysis processing for analyzing the effect instruction command (command stored in the reception buffer of the host RAM 150b) transmitted from the effect control board 120.
When the image control board 150 receives a command transmitted from the effect control board 120, a command reception interrupt process of the image control board 150 (not shown) occurs, and the received command is stored in the reception buffer. Thereafter, the received command is analyzed in step S2030.

The effect instruction command analysis process confirms whether or not an effect instruction command is stored in the reception buffer. If an effect instruction command is not stored in the reception buffer, the process proceeds directly to step S2040.
If a production instruction command is stored in the reception buffer, a new production instruction command is read, and one or more animation groups to be executed are determined based on the read production instruction command. A pattern is determined (see FIG. 20). When the animation pattern is determined, the read effect instruction command is deleted from the transmission buffer.

  In step S2040, the host CPU 150a performs an animation control process. In this process, based on the “scene switching counter”, the “weight frame”, the “frame counter” updated in step S2210, which will be described later, and the animation pattern determined in step S2030, various animation scenes are displayed. Update the address.

In step S2050, the host CPU 150a determines the display list from the display information (sprite identification number, display position, etc.) of the animation scene at the updated address according to the priority (drawing order) of the animation group to which the animation scene belongs. Are generated (see FIG. 21). When the generation of the display list is completed, the host CPU 150a outputs the display list to the VDP 2000. The display list output here will be described later with reference to FIG.
The display list output here is stored in the display list storage area 153a of the VRAM 153 via the CPU I / F 2030 in the VDP 2000.

In step S2060, the host CPU 150a determines whether or not the FB switching flag = 01.
Here, as will be described later with reference to FIG. 19B, the FB switching flag is set to FB if the previous display list has been drawn in the V blank interrupt every 1/60 seconds (about 16.6 ms). Switching flag = 01. That is, in step S2060, it is determined whether or not the previous drawing has been completed.
If the FB switching flag = 01, the host CPU 150a shifts the process to step S2070. If the FB switching flag = 00, the host CPU 150a waits until the FB switching flag = 01.

In step S2070, the host CPU 150a sets the FB switching flag = 00 (turns the FB switching flag off), and proceeds to step S2020.
Thereafter, the processing from step S2020 to step S2070 is repeated until a predetermined interrupt shown in FIG. 19 occurs.

(Image control board interrupt processing)
The interrupt process of the image control board 150 will be described with reference to FIG.

In the interrupt processing of the image control board 150, a drawing end interrupt process performed by inputting a drawing end interrupt signal, a V blank interrupt process performed by inputting a V blank interrupt signal, and a command are received. And at least a command reception interrupt process performed.
Note that the drawing end interrupt process and the V blank interrupt process are described with reference to FIG. 19, but the command reception interrupt process is as described in step S2030 and is not illustrated.

(Image control board drawing end interrupt processing)
FIG. 19A is a diagram illustrating a drawing end interrupt process of the image control board 150. FIG.

When the drawing of a predetermined unit frame (one frame) is finished, the VDP 2000 outputs a drawing end interrupt signal to the host CPU 150a via the CPU I / F 2030.
When the host CPU 150a receives a drawing end interrupt signal from the VDP 2000, the host CPU 150a executes a drawing end interrupt process.

  In the drawing end interrupt process, the host CPU 150a sets the drawing end flag = 01 (turns on the drawing end flag), and ends the current drawing end interrupt process (step S2110). That is, the drawing end flag is turned on every time drawing ends.

(V blank interrupt processing for image control board)
FIG. 19B is a diagram showing a V blank interrupt process for the image control board 150.
The VDP2000 outputs a V blank interrupt signal (vertical synchronization signal) to the host CPU 150a via the CPU I / F 2030 every 1/60 seconds (about 16.6 ms).
When the host CPU 150a receives a V blank interrupt signal from the VDP 2000, the host CPU 150a executes a V blank interrupt process.

  In step S2210, the host CPU 150a performs processing for updating various counters such as “scene switching counter”, “wait frame”, and “frame counter”.

In step S2220, the host CPU 150a determines whether or not the drawing end flag = 01. That is, it is determined whether or not drawing of a predetermined unit frame has been completed.
If the drawing end flag = 01, the host CPU 150a moves the process to step S2230. If the drawing end flag = 01, the host CPU 150a ends the current V blank interrupt process. That is, even if the V blank interrupt signal is input, if the drawing is not completed, the processing after step S2230 is not performed.

  In step S2230, the host CPU 150a sets a drawing end flag = 00 (turns the drawing end flag off).

In step S 2240, the host CPU 150 a gives an instruction to switch between the “display frame buffer” and the “drawing frame buffer” to the memory controller 2090 of the VDP 2000.
Specifically, the host CPU 150a performs a process of adding 1 to the first bit of the display register via the CPU I / F 2030 (see FIG. 6D).

  In step S2250, the host CPU 150a sets the FB switching flag = 01 (turns on the FB switching flag), cancels the standby state in step S2060, and ends the current V blank interrupt processing.

  Next, with reference to FIGS. 20 and 21, an animation pattern determination method and a display list generation method will be described.

(Anime pattern)
FIG. 20 is an example of an animation pattern for displaying an animation of a production pattern.

As shown in FIG. 20A, the animation pattern is grouped for each object or scene displayed on the liquid crystal display device 31, and displays a background group for displaying the background animation and an animation of the character used for the notice A. Notice group A to perform, kaleidoscope production group that defines the timing of processing in kaleidoscope production processing, reach group to display reach character animation, production design group to display animation of production design 36, jackpot There are a number of groups such as a jackpot production group for displaying production animations. A large number of animation patterns are associated with each group and stored in the host ROM 150c.
Based on the effect pattern designation command received from the sub CPU 120a, the host CPU 150a determines one or a plurality of animation groups to be executed and determines an animation pattern from each animation group.

  FIGS. 20B to 20E show an example of an animation pattern including a kaleidoscope effect group, which is determined when an effect pattern designation command corresponding to a variable effect including a kaleidoscope effect process is received.

  When the host CPU 150a receives the change effect pattern designation command corresponding to the change effect including the kaleidoscope effect process, the host CPU 150a determines four groups of the background group, the notice A group, the kaleidoscope effect group, and the effect symbol group, The anime pattern 1 is determined from the background group, the anime pattern 11 from the notice A group, the anime pattern 21 from the kaleidoscope production group, and the anime pattern 501 from the production design group.

Here, as shown in FIGS. 20B to 20E, the animation pattern stores a combination of animation scene information, a display order of each animation scene information, and the like.
For example, in the kaleidoscope production group / animation pattern 21 shown in FIG. 20D, the animation scene 0 is executed first, and the animation scene 21 is executed second. The host RAM 150b has a “scene switching counter” that is updated every frame. When the scene switching counter measures 180 while the first animation scene 0 is being executed, the second animation scene 21 is updated. The animation scene changes. When the scene switching counter measures 300 while the second animation scene 21 is being executed, the animation scene of the kaleidoscope production group / animation pattern 501 ends.

Also, for example, in the effect symbol group / animation pattern 501 shown in FIG. 20 (e), the animation scene 501 is executed first and the animation scene 511 is executed second. If the scene switching counter measures 540 while the first animation scene 501 is being executed, the animation scene is switched to the second animation scene 511. When the scene switching counter measures 60 while the second animation scene 511 is being executed, the animation scene of the production symbol group / animation pattern 501 ends.
Note that “one frame” is the update timing of the liquid crystal display device (update timing of the vertical synchronization signal), and one frame is updated every 1/60 seconds (about 16.6 ms). That is, 60 frames are measured in 1 second. In the present embodiment, a display image is formed for each frame. That is, the number of elapsed frames is equivalent to the number of display images formed.

Each animation scene stores animation scene information, and wait frames (that is, display time) updated every frame, target data (sprite identification number, transfer source address, etc.), parameters (sprite Display information such as a display position, a transfer destination address, and a drawing method.
For example, in the animation scene 21 shown in FIG. 20D, a processing process related to a kaleidoscope effect described later is performed for 5 seconds from the 181 frame to the 300 frame. Also, in the animation scene 501 shown in FIG. 20 (e), the first design to the fourth design are initially displayed up to 20 frames (about 0.33 seconds) at predetermined coordinates. Thereafter, the first symbol to the fourth symbol are continuously displayed at different coordinates for up to 15 frames (about 0.25 seconds). Similarly, when the first symbol to the fourth symbol are continuously displayed at different coordinates up to a predetermined frame, an animation is displayed in which the first symbol to the fourth symbol is moved and displayed. be able to.

Then, as shown in FIGS. 20 (b) to 20 (e), the anime pattern 1 of the background group, the anime pattern 11 from the notice A group, the anime pattern 21 from the kaleidoscope production group, and the animation from the production design group A plurality of animation patterns with the pattern 501 are determined, and the animations of these animation patterns are executed in parallel.
That is, images of BG1 (mountains) and BG2 (clouds) continue to be displayed as the background from the start to the end of the animation pattern in the display area of the liquid crystal display device 31, and 2 seconds (120 frames from the start of the animation pattern). ) After that, the image for performing the animation of the notice display of the character A is displayed for 3 seconds (180 frames), and after 3 seconds (180 frames) from the start of the animation pattern, the image for performing the kaleidoscope effect is displayed for 5 seconds (300 frames). . Furthermore, an image for performing animation for normal variation display of effect symbols is performed for 9 seconds (540 frames), and then an image for performing animation for temporary stop display for 1 second (60 frames) is displayed.
Note that these images are displayed in an overlapping manner in the display area of the liquid crystal display device 31, and the first drawn image is overwritten by the later drawn image and erased. This image generation method will be described in the next display list.

(Display list)
FIG. 21 is an example of a display list including drawing control command groups.

  When the host CPU 150a determines the animation pattern as shown in FIG. 20, the host CPU 150a generates a display list for each predetermined frame (one frame), and outputs the generated display list to the VDP 2000.

  Here, regarding the display list generation method, the host CPU 150a follows the contents of the animation scene at the current number of frames based on the “frame counter” indicating the current frame and the determined animation pattern (anime scene). By generating the drawing control commands according to the priority order (drawing order) of each animation group, a display list for the current number of frames is generated. Note that, at the generation timing of the display list related to the frame for which the kaleidoscope effect process is performed, as shown in FIG. 21, a display list including a processing command for performing the kaleidoscope effect process is generated.

  For example, as the priority of the animation group, the lowest priority 10 data is associated with the background group, the priority 9 data is associated with the notice A group, and the priority 8 data is associated with the notice B group. ,..., Data of priority 2 is associated with the jackpot effect group, and data with the highest priority 1 is associated with the effect symbol group.

And, the anime pattern 1 of the background group, the anime pattern 11 from the notice A group, the anime pattern 21 from the notice B group, and the anime pattern 501 from the production design group are determined. To do.
Next, drawing control commands according to the contents of the animation scene in the current frame counter (current number of frames) are sequentially generated from the animation pattern 1 of the lowest priority animation group (background group). In the present embodiment in which the kaleidoscope effect is performed, processing commands are generated with a predetermined priority. An image related to an animation group having a lower priority than the processing command is a back image that is a target image for performing kaleidoscope effect processing. Subsequently, drawing control commands related to the animation group having a higher priority than the processing command are sequentially generated, and drawing control commands up to the highest priority animation group (direction symbol group) among the determined animation groups are generated. When it is generated, a drawing end command is finally generated to complete a display list as shown in FIG.
Such a display list is generated by program processing while referring to necessary data by the host CPU 150a.

  As described above, when the host CPU 150a outputs a display list in which drawing control command groups are grouped in predetermined frames (one frame) to the VDP 2000, the drawing circuit 2070 in the VDP 2000 performs specific drawing processing. The processing load on the host CPU 150a can be reduced.

  Next, processing executed in VDP2000 will be described.

(Expansion circuit expansion control processing)
The decompression control processing of the decompression circuit 2060 in VDP2000 will be described using FIG.

First, in step S2310, the decompression circuit 2060 determines whether or not there has been an instruction to start decompression execution for decompressing image data to be rendered from the rendering circuit 2070. Specifically, it is determined whether or not decompression execution start data is set in the decompression register by the drawing circuit 2070 (whether or not 1 is set in the 0th bit of the decompression register) (see FIG. 6C).
When there is an instruction to start decompression execution, the decompression circuit 2060 moves the process to step S2320, and when there is no instruction to start decompression execution, the decompression circuit 2060 waits until there is an instruction to start decompression execution.

  In step S2320, the decompression circuit 2060 clears the decompression start data of the decompression register set by the drawing circuit 2070 (sets 0 to the 0th bit of the decompression register).

  In step S2330, the decompression circuit 2060 sets decompression execution data in the decompression register (sets 1 to the 1st bit of the decompression register) in order to inform the drawing circuit 2070 that decompression is being performed (FIG. 6 ( c)).

  In step S2340, the decompression circuit 2060 reads the compressed image data compressed in the CRROM 151, decompresses the read compressed image data to the original image data, and decompresses the decompressed image data in the decompression storage area 153b of the VRAM 153. Let

In step S2350, the decompression circuit 2060 determines whether decompression of one image has been completed.
In the decompression circuit 2060, when decompression of one image is completed, the process proceeds to step S2360. When decompression of one image is not completed, the process returns to step S2340 and the decompression process is repeated.

  In step S2360, when the decompression circuit 2060 completes decompression of one image, the decompression register 2070 clears the decompression execution data in the decompression register in order to notify the rendering circuit 2070 that decompression has ended (sets 0 to the 1-bit of the decompression register). Then, the process returns to step S2310 to repeat the expansion control process.

(Drawing control process in drawing circuit)
A drawing control process of the drawing circuit 2070 in the VDP 2000 will be described with reference to FIG.

In step S2410, the drawing circuit 2070 determines whether there is an instruction to start drawing from the host CPU 150a. Specifically, the host CPU 150a determines whether or not drawing execution start data is set in the drawing register (whether or not 1 is set in the 0th bit of the drawing register) (see FIG. 6B). .
The drawing circuit 2070 shifts the process to step S2420 when there is an instruction to start drawing, and waits until there is an instruction to start drawing when there is no instruction to start drawing.

  In step S2420, the drawing circuit 2070 clears the drawing execution start data of the drawing register set by the host CPU 150a (sets 0 in the 0 bit of the drawing register).

In step S2430, the drawing circuit 2070 reads the display list stored in the display list storage area 153a of the VRAM 153, and sequentially analyzes the drawing display control commands of the read display list according to a predetermined priority (drawing order). Go.
Here, not all of the plurality of drawing control commands in the display list are analyzed at once. In one display list analysis control process, a predetermined unit (drawing order) is used in accordance with a predetermined priority (drawing order). For example, a drawing control command of one image data) is sequentially analyzed.

  In step S2440, the drawing circuit 2070 stores a decompression command for decompressing the compressed image in the display list. Instruct 2060 to decompress the image data to be drawn. Specifically, decompression start data is set in the decompression register (1 is set to 0 bit of the decompression register).

In step S2450, the drawing circuit 2070 determines whether the expansion of the image to be drawn has been completed. Specifically, it is determined whether or not the decompression execution data is cleared in the decompression register (whether or not 0 is set in the first bit of the decompression register).
The drawing circuit 2070 shifts the process to step S2460 when the drawing image has been decompressed, and waits until the drawing image has been decompressed when the drawing image has not been decompressed.

In step S2460, the drawing circuit 2070 confirms whether the current display list drawing control command is a processing command for performing kaleidoscope effect processing when drawing according to the priority order.
If the drawing control command is not a processing command, the process proceeds to step S2461, and the drawing circuit 2070 decompresses the data to the expanded storage area 153b of the VRAM 153 while appropriately setting necessary data in the drawing register in accordance with the display list drawing control command. A drawing process is performed to draw the processed image in a “drawing frame buffer” in the VRAM 153.

On the other hand, if the drawing control command is a processing command in step S2460, the process proceeds to step S2462, and the drawing circuit 2070 follows the processing command and the drawing frame based on the drawing control command having a lower priority than the processing command. Processing for the kaleidoscope effect processing is performed on the back image, which is an image already drawn in the buffer. The drawing circuit 2070 processes the back image using the processing area 153e in the VRAM 153 as a work area, and stores the processed image in the drawing frame buffer.
The specific processing content of the processing process will be described in detail later.

In step S2470, the drawing circuit 2070 determines whether all the drawing control commands in the display list of one frame have been completed (drawing processing of one frame has been completed).
When the drawing process for one frame is completed, the drawing circuit 2070 shifts the process to step S2480. When the drawing process for one frame is not completed, the drawing circuit 2070 returns the process to step S2430, and the drawing process for one frame is completed. Until the process is completed, the “display list analysis control process” in step S2430, the “decompression instruction process” in step S2440, and the “drawing process” in step S2460 are repeated.
If all the image data is compressed and stored in the CGROM 151 as in the present embodiment, the image is expanded and drawn for each image according to the display list.

  In step S2480, the drawing circuit 2070 sets the drawing end data in the interrupt register (sets 1 in the first bit of the system control register) (see FIG. 6A), and returns the processing to step S2410 to control drawing. Repeat the process.

(Processing related to kaleidoscope effect processing)
Here, a processing process related to the kaleidoscope effect process will be described with reference to FIG. FIG. 24 is an explanatory diagram for explaining the processing procedure of the processing process.

  As shown in FIG. 24 (a-1), a unit image region a1 having a right isosceles triangle shape is selected from the back image which is a target image on which kaleidoscope effect display is performed. The position of the unit image area when creating the first frame of kaleidoscope effect display may be a predetermined position such as the center or edge of the back image, or an arbitrary position may be selected.

Next, as illustrated in FIG. 24A-2, a modified image for generating a display image is generated using the unit image included in the selected unit image region. Specifically, an inverted image a2 obtained by horizontally inverting the unit image, an inverted image a3 inverted vertically, and an inverted image a4 inverted vertically and horizontally are generated. Then, the unit image a1 in the unit image area is combined with these inverted images a2, a3, and a4 to generate a square-shaped deformed image a5.
Next, as shown in FIG. 24A-3, a plurality of modified images a5 are arranged in the display area, and the processed image subjected to the kaleidoscope effect process is drawn in the drawing frame buffer.

In this embodiment, the unit image area has a right-angled isosceles triangle shape, and the deformed image has a square shape formed by combining four right-angled isosceles triangle shapes. However, the present invention is not limited to this. For example, the unit image area may have a square shape, and the deformed image may have a square shape in which a plurality of squares are combined. The unit image area may be a rectangle, and the deformed image may be a rectangle formed by combining a plurality of rectangles. The unit image area may be an equilateral triangle, and the deformed image may be a parallelogram, trapezoid, or hexagon formed by combining a plurality of equilateral triangles. The shape of the unit image region and the shape of the deformed image formed by combining them are not limited to those described above, and various shapes may be adopted.
In addition, the reverse image is generated by performing the reverse process on the unit image. However, the rotated image may be generated by performing the rotation process, and the deformed image may be generated by using the rotated image. The reverse image generated by performing the reverse process. A deformed image may be generated by combining an image and a rotated image generated by performing rotation processing.

  Here, in the kaleidoscope effect processing of the present embodiment, the position of the unit image area is moved every predetermined number of frames (that is, a predetermined number of display images generated) or every predetermined time. When the position of the unit image area is moved, the image included in the unit image area is changed, so that the image of the deformed image is also changed, and the processed image subjected to the kaleidoscope effect process is also changed. That is, by moving the unit image area every predetermined number of frames or every predetermined time, the display image can be changed every predetermined number of frames or every predetermined time.

The predetermined number of frames is not particularly limited, and can be, for example, about several frames to several tens of frames. The predetermined time is not particularly limited, and can be, for example, about several tens of milliseconds to several hundreds of milliseconds. By setting in this way, the image can be changed smoothly as when the image of the kaleidoscope changes.
Further, by moving the unit image area continuously and smoothly, the image can be changed smoothly as when the image of the kaleidoscope changes. However, the present invention is not limited to moving the position of the unit image area smoothly and continuously, and the position of the next unit image area may be selected as an arbitrary position when moving the unit image area.

  Furthermore, the kaleidoscope effect processing of the present embodiment enlarges the size of the unit image area every predetermined number of frames (that is, a predetermined number of display images generated), every predetermined time, or every change. FIGS. 24B-1 to 24B-3 show specific processing contents of the kaleidoscope effect processing for enlarging the size of the unit image region. First, as shown in FIG. 24 (b-1), when the kaleidoscope effect display is started and a predetermined number of frames or a predetermined time has elapsed or one change has been completed, the size of the unit image area is enlarged and The unit image area b1 is selected. In FIG. 24 (b-1), the position of the unit image area b1 is different from the position of the unit image area a1 shown in FIG. 24 (a-1) as the game progresses. Next, as shown in FIG. 24 (b-2), inverted images b2, b3, and b4 are generated using the unit images included in the selected unit image region b1, and the modified image b5 is used using these inverted images. Is generated. Next, as shown in FIG. 24 (b-3), a plurality of modified images b5 are arranged in the display area and a processed image subjected to kaleidoscope effect processing is drawn in the drawing frame buffer.

  24 (c-1) to (c-3) show the specific processing contents of the kaleidoscope effect processing when the size of the unit image area is further enlarged. First, as shown in FIG. 24 (c-1), when a predetermined number of frames or a predetermined time has elapsed or one change has been completed since the previous unit image area was expanded, the size of the unit image area is further expanded. The unit image area c1 is selected from the back image. In FIG. 24 (c-1), the position of the unit image area c1 is different from the position of the unit image area b1 shown in FIG. 24 (b-1) as the game progresses. Next, as illustrated in FIG. 24C-2, inverted images c2, c3, and c4 are generated using the unit images included in the selected unit image region c1, and the deformed image c5 is generated using these inverted images. Is generated. Next, as shown in FIG. 24 (c-3), a plurality of modified images c5 are arranged in the display area and a processed image subjected to kaleidoscope effect processing is drawn in the drawing frame buffer.

  As shown in FIG. 24, the kaleidoscope effect processing of the present embodiment enlarges the size of the unit image region for each predetermined number of frames, a predetermined time, and one change. When the size of the unit image area is enlarged, the range of the image included in the unit image area is enlarged, and the size of the deformed image is also enlarged, so the content of the back image is inferred from the content of the processed image subjected to the kaleidoscope effect processing. It becomes easy. That is, by enlarging the unit image area for each predetermined number of frames, predetermined time, or one change, the contents of the back image can be changed from the display image so that it can be more easily estimated from the predetermined number of frames or predetermined time.

  Here, the predetermined number of frames, which is an interval for enlarging the size of the unit image area, is not particularly limited, but may be, for example, several hundred frames to several tens of thousands frames. Further, the predetermined time is not particularly limited, and can be, for example, about several seconds to several minutes. By setting in this way, it is possible to increase the ease of guessing step by step while giving the player time to guess the back image from the display image. Thereby, the player's desire to guess the back image can be enshrined, and the interest of the player can be improved.

(Processing of image control board)
The processing related to the kaleidoscope effect processing by the drawing circuit 2070 will be described with reference to FIG. FIG. 25 is a flowchart for explaining the processing procedure of the processing in step S2462 in FIG. In the following description, the unit image area is moved and enlarged every time a predetermined number of frames have elapsed.

  In step S2610, it is determined whether a predetermined number of frames has elapsed since the unit image area was last changed. If the predetermined number of frames has elapsed since the last change of the unit image area, the process advances to step S2620 to move from the position of the unit image area selected in the previous frame. On the other hand, if the predetermined number of frames has not elapsed since the last change of the unit image area, the process advances to step S2630 to select the unit image area at the same position as the unit image area selected in the previous frame. To do. The position of the unit image region refers to the position of a vertex having an angle of 90 ° in a right-angled isosceles triangle, but is not limited to this and may be another vertex, or the position of the center of gravity of a right-angled isosceles triangle, An arbitrary point on the unit image area may be set as the position of the unit image area.

  In step S2640, it is determined whether a predetermined number of frames has elapsed since the previous change in the size of the unit image area. If the predetermined number of frames has elapsed since the size of the unit image area was changed, the process proceeds to step S2650, and the size of the unit image area is increased. On the other hand, if the predetermined number of frames has not elapsed, the process advances to step S2660 to set the size of the unit image area to the same size as the size of the unit image area in the previous frame. The size may be enlarged around the vertex defined as the position of the unit image area. In step S2640, if the size of the unit image area has not been changed since the start of the kaleidoscope processing effect, it is determined whether a predetermined number of frames have elapsed since the start of the kaleidoscope effect processing.

  Here, in the present embodiment, it is determined in step S2640 whether or not a predetermined number of frames have elapsed since the previous change of the size of the unit image area. However, the present invention is not limited to this. For example, in step S2640, it may be determined whether a predetermined number of frames have elapsed since the kaleidoscope effect was started. That is, the number of frames from the start of the kaleidoscope effect until the unit image area size is changed may be set in advance, and it may be determined whether or not the number of frames has been reached.

  Proceeding to step S2670, a unit image area is selected at the determined position and size from the image already drawn in the drawing frame buffer by a drawing command having a lower priority than the processing command, and is included in the unit image area. An image is extracted and stored in the processing area 153e of the VRAM 153. In step S2680, the unit image area image is inverted to form an inverted image, and these are combined to generate a deformed image. In step S2690, a plurality of modified images are arranged, and the processed image is drawn in the drawing buffer.

(Display control processing in display circuit)
A display control process of the display circuit 2080 in the VDP 2000 will be described with reference to FIG.

In step S2510, the display circuit 2080 determines whether there is an instruction to create a video signal from the host CPU 150a. Specifically, it is determined whether 1 is set in the 0th bit of the display register (see FIG. Ω (d)).
If there is an instruction to create a video signal, the display circuit 2080 moves to step S2520. If there is no instruction to create a video signal, the display circuit 2080 waits until there is an instruction to create a video signal.
As a general rule, the 0th bit of the display register remains set to “1” from the time of power-on (the video signal creation ON state is maintained from the time of power-on).

  In step S2520, the display circuit 2080 generates an RGB signal (analog signal) indicating image color data as a video signal from the image data (digital signal) stored in the “display frame buffer” in the VRAM 153.

  In step S 2530, the display circuit 2080 outputs the generated video signal (RGB signal) and a synchronization signal (vertical synchronization signal, horizontal synchronization signal, etc.) for synchronizing with the liquid crystal display device 31 to the liquid crystal display device 31. . Thereafter, the process returns to step S2510 to repeat the display control process.

  Next, the outline of the effect control board 120 will be briefly described.

  When the effect control board 120 receives a command transmitted from the main control board 110, a command reception interrupt process of the effect control board 120 occurs, and the received command is stored in the reception buffer.

  Then, the sub CPU 120a in the effect control board 120 analyzes the received command and generates various commands corresponding to each command in the timer interrupt process of the effect control board 120 performed every 2 ms. Thereafter, the generated various commands are transmitted to the image control board 150 and the lamp control board 140.

  For example, when the sub CPU 120a in the effect control board 120 receives the variation pattern designation command from the main control board 110, the sub CPU 120a analyzes the content of the received variation pattern designation command, and the liquid crystal display device 31, the audio output device 32, the effect drive. A command for causing the device 33 and the effect lighting device 34 to execute a predetermined effect is generated, and the command is transmitted to the image control board 150 and the lamp control board 140.

  Next, the outline of the lamp control board 140 and the image control board 150 will be briefly described.

  In the lamp control board 140, upon receiving the production command from the production control board 120, the production drive device operation program is read based on the received production command, and the production drive device 33 is operated and controlled. The effect lighting device control program is read based on the received effect command, and the effect lighting device 34 is controlled.

  In the image control board 150, when the production command is received from the production control board 120, the audio CPU reads out the audio output device control program from the audio ROM based on the received production command, and the audio in the audio output device 32 is read. And the host CPU 150a reads the animation control program from the image ROM and controls the image display on the liquid crystal display device 31.

Here, the pseudo-continuous effect is an effect that makes it appear to the player as if the symbol has fluctuated / stopped multiple times (substantially one fluctuation / stop). In other words, it is an effect that makes it appear as if multiple changes / stops are made by making a temporary stop multiple times to make it appear as if the symbol is stopped in one change.

At this time, similarly to the state shown in FIG. 27D, the unit image area size is enlarged at the timing when the temporary stop of the effect symbol 36 ends and re-varies. That is, in this embodiment, the unit image area size is set to be enlarged when the number of frames from the start of kaleidoscope effect display to the end of the second temporary stop display of the effect symbol 36 has elapsed.
Similar to the state shown in FIG. 27 (d), the variation display of the effect symbol 36 is performed with the kaleidoscope effect display being performed. Further, the unit image region position related to the kaleidoscope effect display continuously moves every predetermined number of frames.

Can do.

  As an example shown in FIG. 27, an example is given in which the kaleidoscope effect process is performed so as to enlarge the size of the unit image area for each re-variation in the pseudo-continuous effect, but the present embodiment is not limited to this. For example, kaleidoscope effect processing may be performed over a plurality of variations. That is, the size of the unit image area may be enlarged for each change. Thereby, the contents of the back image can be easily understood for each change in the effect design.

  As described above, according to the present embodiment, the display image is formed using only the image included in the unit image area, that is, the display image is generated by combining the deformed images generated from the unit images included in the unit image area. The player cannot easily understand the contents of the back image, but can guess it. Thereby, it can be made to concentrate on a game so that a player may guess a content, and an interest can be improved.

  Further, according to the present embodiment, when generating a deformed image, predetermined processing such as inversion processing and rotation processing is performed on the unit image included in the unit image region. As a result, the player can understand the unit image included in the unit image area, and cannot easily understand the content of the back image, but can guess it. Therefore, it is possible to concentrate on the game by letting the player guess the contents, and to improve the interest.

  Further, according to the present embodiment, the information for estimating the display content can be changed by moving the unit image area and changing the image included in the unit image according to the progress of the game. Enthusiasm for guessing the display content of can be improved. Further, by changing the display image by moving the unit image area, it is possible to perform a new effect that has not been heretofore and to improve the interest.

  Further, according to the present embodiment, the size of the unit image area is changed so as to increase stepwise according to the predetermined condition. Thereby, according to progress of a game, it can change in steps so that the content of a display image may be estimated more easily. Therefore, the player can gradually understand the contents of the back image as the game progresses, and the interest can be improved.

  In the present embodiment, the back image drawn in the drawing frame buffer is selected as the target image for the kaleidoscope effect process, and the unit image area is selected and the unit image is extracted. However, the present invention is not limited to this. For example, an image stored in the CGROM 151 may be drawn in the processing area 153e, a unit image area may be selected and a unit image may be extracted from the image, and a processed image subjected to kaleidoscope effect processing may be generated. .

  In the present embodiment, the specific direction side of the game area is the second game area on the right side, but may be the first game area on the left side.

  In this embodiment, one frame is updated every 1/60 seconds (about 16.6 ms). However, one frame may be updated every 1/30 seconds, or every 1/120 seconds. One frame may be updated every time. In other words, the design cycle can be freely changed for one frame update period.

  In the present embodiment, one frame is updated and the next frame is drawn when drawing by the drawing circuit 2070 is completed. However, by updating one frame, the next frame is always updated. You may comprise so that the frame of this may be drawn.

  In the present embodiment, on the condition that the drawing is finished, each frame is updated so that the next frame can be drawn. However, every time two frames are updated, the next frame is updated. It may be configured to be able to draw a frame, or may be configured to be able to draw the next frame every time three frames are updated, that is, one frame. The update cycle and the drawing cycle of the drawing circuit may not be the same.

  Moreover, according to this embodiment, although the game machine used for a pachinko game machine was demonstrated, you may use for a swing type game machine (slot machine), a sparrow ball game machine, and an arrange ball game machine.

  The specific configuration of the gaming machine 1 according to the embodiment of the present invention described above is not limited to the embodiment, and the present invention can be applied even if there is a design change or the like without departing from the gist of the present invention. included.
