Description

  The present invention relates to a pachinko gaming machine, and more particularly to refresh processing of an image memory storing effect image data.

In general, a pachinko machine is an CGROM (Character Generator Read Only Memory) that stores an image display constituted by a liquid crystal display panel such as a liquid crystal display device, and image data such as decorative symbols and effect images displayed on the image display. ).
As a prior art document, Patent Document 1 discloses a game machine including a display unit for displaying an image and a CGROM for storing image data for display.

JP 2008-289786 A

In conventional pachinko machines, a NOR-type ROM that can be read in 1-byte units and can be accessed at high speed has been used as a CGROM. However, in recent years, with the increase in the capacity of production image data, CGROM is in demand.
However, since the NOR-type ROM is expensive, there is a problem that a significant increase in cost is caused if the NOR-type ROM is used to increase the capacity of the CGROM.
Therefore, in order to solve such a problem, it is conceivable to adopt a NAND flash memory as a CGROM which is cheaper than the NOR ROM.

However, the NOR type ROM does not need to perform a refresh process, which is a process of injecting charges again in reading, whereas the NAND flash memory needs to perform a refresh process for every several thousand readings. . In order to execute the refresh process at an appropriate timing, it is necessary to check the number of readings. In this case, there is a problem that the effect image is stopped and the image is disturbed depending on the processing time required for the check.
Therefore, in order to solve such problems, it is conceivable to perform refresh processing every time the pachinko gaming machine is turned on regardless of the number of times of reading, but when refresh processing is performed every time the power is turned on, At the time of shipping inspection in the manufacturing process, there is a problem that the refresh process is performed every time the power is turned on, and the production efficiency is remarkably deteriorated.

  The present invention has been made in view of the above-described points. By adopting a NAND flash memory as a CGROM for storing effect image data, the display operation and production efficiency of effect images can be reduced while reducing costs. It is an object of the present invention to provide a pachinko gaming machine that can perform a refresh operation without deteriorating.

The present invention has been made to solve the above-described problems, and can be realized by the following modes.
That is, according to the first aspect of the present invention, there is provided an image display means capable of displaying an effect image, an effect control means for controlling an effect image displayed on the image display means, and an image data storage means for storing effect image data. And the image data storage means is constituted by a NAND flash memory, and the effect control means is configured to store the image data in a predetermined period in which access for reading image data is not performed with respect to the image storage means. A refresh process of the means is executed.

  According to the first embodiment, the image data storage means is constituted by the NAND flash memory, so that the cost can be reduced as compared with the case where the image data storage means is constituted by the conventional NOR type flash memory. In addition, the effect control means performs a refresh process during a predetermined period when the image storage means is not accessed to read out the image data, so that the effect image displayed on the image display means is stopped and the image is displayed. There will be no troubles such as disturbance. Further, since it is not necessary to perform the refresh process when the power is turned on, the refresh process can be performed without impairing the production efficiency.

The second aspect of the present invention is characterized in that the effect control means performs the refresh process in a time-sharing manner in the predetermined period.
According to the second embodiment, the refresh process of the image storage unit can be performed even when the time allotted to one refresh process is short.

The third aspect of the present invention is characterized in that the predetermined period is a period in which an effect image displayed on the image display means is stopped.
According to the third aspect, it is possible to perform the refresh process of the image storage means by using the stop period of the effect image in which the time allocated for the refresh process per time is short.

The fourth aspect of the present invention is characterized in that the predetermined period is a customer waiting standby period in which a customer waiting screen is displayed on the image display means.
According to the fourth aspect, since the time allocated for one refresh process can be increased, the refresh process of the image storage means can be performed with a small number of processes.

According to a fifth aspect of the present invention, the predetermined period is a period during which a still image is displayed on the image display means.
According to the fifth aspect, the refresh process of the image storage unit can be performed using the period during which the still image is displayed on the image display unit.

According to the present invention, since the image storage means for storing the effect image is configured by using the NAND flash memory, the cost can be reduced as compared with the case of configuring by the conventional NOR flash memory.
Further, the effect control means performs a refresh process during a predetermined period in which the image storage means is not accessed for reading out the image data, so that the effect image displayed on the image display means is stopped and the image is displayed. There is no such thing as disturbance.
Further, since it is not necessary to perform a refresh process when the power is turned on, production efficiency is not impaired.

In the game control device shown in FIG. 2, a main control board 111 for controlling the progress of the game is provided as a main control board, and an effect control board 121 and an image control board 131 are provided as sub (sub) control boards. A lamp control board 141, a payout control board 151, and the like are provided.
The main control board 111 includes a CPU 112, a ROM 113, and a RAM 114, and performs main control of the pachinko gaming machine.
The main control board 111 includes a first start port SW13a provided in the upper start port 13, a second start port SW14a provided in the electric chew 14, an electric chew solenoid 14b for opening and closing the electric chew 14, and a gate 15 Are connected to the gate SW15a, the large winning opening SW16a for detecting the game ball won in the large winning opening 16, the large winning opening solenoid 16b for opening and closing the opening / closing door of the large winning opening 16, and the normal winning opening SW17a.

Also, the first special symbol hold lamp 24, the second special symbol hold lamp 25, the normal symbol hold lamp 26, the first special symbol display 21, the second special symbol display 22, and the normal symbol display 23 are connected. Yes. The main control board 111 is connected to the effect control board 121 and the payout control board 151.

The effect control board 121 includes a CPU 122, a ROM 123, a RAM 124, and an RTC (real time clock) 125, and controls the entire game effect. For this reason, the image control board 131, the lamp control board 141, and the effect button 104 are connected to the effect control board 121.
The image control board 131 that constitutes the effect control means together with the effect control board 121 includes a CPU 132, a ROM 133, a RAM 134, a CGROM 135, and a sound data ROM 136, and controls output of images and sounds based on instructions from the effect control board 121. Do. For this reason, the image display board 11 and the speaker 105 are connected to the image control board 131.

The CGROM 135 is configured by a NAND flash memory, and stores image data of decorative designs and various effect images displayed on the image display 11.
The sound data ROM 136 is configured by, for example, a NOR flash memory, and stores various sound data output from the speaker 105. Of course, the sound data ROM 136 can be constituted by a NAND flash memory.
Further, the CPU 132 of this embodiment has a refresh function for executing the refresh process of the CGROM 135.

The lamp control board 141 includes a CPU 142, a ROM 143, and a RAM 144, and controls the frame lamp 145, the panel lamp 146, the movable accessory 147, and the like.
The payout control board 151 includes a CPU 152, a ROM 153, and a RAM 154, and performs drive control of the payout drive motor 155 of the payout device that pays out game balls.

In the pachinko gaming machine 100 according to the present embodiment configured as described above, the main control board 111 advances the game when the game ball enters the first start port SW13a or the second start port SW14a. Control. For example, when it is determined that the jackpot is won, the execution of the jackpot game is controlled as a special game.
In the jackpot game, for example, a period until the grand prize winning hole 16 is opened for a predetermined time (for example, 29.5 seconds) or a predetermined number (for example, nine) of game balls is won in the big prize winning hole 1 is 1 A game per long game that repeats the opening action as a round (15 rounds), and a time when the jackpot round is 15 rounds and the open time of the grand prize winning opening 16 in one round is extremely shorter than the above long time (for example, 0 .052 seconds). The main control board 111 also enables execution control of a small hit game in which the game state does not change before and after the opening / closing door 19 of the special winning opening 16 operates in the same manner as the short hit described above.
In the present embodiment, the number of rounds at the time of long hit or small hit has been described as 15 rounds, but the number of rounds is merely an example and can be arbitrarily set.

Here, a random number table of various random values acquired when the entrance of a game ball is detected on the main control board will be described.
FIG. 3 is a random number table for acquiring various random numbers of game data. FIG. 3 (a) is an example of a jackpot random number table for acquiring a jackpot random number, and FIG. 3 (b) is a jackpot symbol random number. FIG. 3C is an example of a reach random number table for acquiring reach random numbers.
In the jackpot random number table shown in FIG. 3 (a), when a game ball is detected at the first start port SW13a or 14a in the upper start port 13 or the electric chew 14, the range from "0" to "299" is detected. One random number value is acquired from among 300 random numbers. In the case of the jackpot random number table shown in FIG. 3A, in the normal gaming state (low probability gaming state), the jackpot ratio is set to 1/300, for example, and the jackpot random number value is “3”. It is determined.
On the other hand, in the high-probability gaming state, the jackpot ratio is set to 10/300, which is 10 times, and the acquired jackpot random number values are “3”, “7”, “37”, “67”, “97”, “127”. ”,“ 157 ”,“ 187 ”,“ 217 ”, and“ 247 ”are determined to be big hits.
In addition, in the jackpot random number table shown in FIG. 3A, a lottery lottery, which is a type of lose, is also performed. Here, the small hit ratio is set to 6/300, and the acquired big hit random number value is “0”, “50”, “100”, “150”, “200”, “250”. Determined.

Next, in the jackpot symbol random number table shown in FIG. 3B, one random number value is acquired from 200 random numbers from “0” to “199”.
For example, when the acquired jackpot symbol random number value is “0” to “55”, it is determined that the per unit length is high probability. The high probability short-term per-hit is a jackpot with both a high-probability game and a short-time game given after the jackpot game is over, and the large opening time of the big prize opening 16 at the time of the jackpot game can be expected. This corresponds to the so-called “probability big hit”.

  Further, for example, when the acquired random number value of the jackpot symbol is “56” to “111”, it is determined that it is per normal short length. In the case of a regular short-length head, the opening time of the big winning opening 16 at the time of the jackpot game is long and it can be expected to pay out a large number of balls, and after the jackpot game ends, the special symbol changes until a predetermined number of times (for example, 100 times) It is a jackpot that has been given a short-time game for a period, and corresponds to a so-called “ordinary jackpot”.

Further, for example, when the acquired random number value of the jackpot symbol is “112” to “118”, it is determined that the short chance with short time with high probability. The short win with high probability is a jackpot that has been given both high-probability game and short-time game after the jackpot game ends, although the opening time of the big prize opening 16 at the time of the jackpot game is short and the payout of the ball cannot be expected. Corresponds to a “big hit”.
For example, when the random number value of the acquired jackpot symbol is “119” to “121”, it is determined that the short hit with normal time is short. The normal short-term short win is the time until the special symbol changes for a predetermined number of times (for example, 100 times) after the big hit game ends, although the opening time of the big winning opening 16 at the time of the big hit game is short and the payout of the ball cannot be expected. This is a jackpot with a short-time game, which corresponds to a so-called “collision jackpot”.

For example, when the random number value of the acquired jackpot symbol is “122” to “195”, it is determined that there is a high probability short-time short hit. The high probability short / short short hit is a big hit that has been given a high probability game after the jackpot game ends, although the opening time of the big prize opening 16 at the time of the jackpot game is short and expectation of payout of the ball is not expected. It corresponds to.
For example, when the random number value of the jackpot symbol is “196” to “199”, it is determined that the normal time is short and short. The normal short / short short hit is a big hit in which the opening time of the big prize opening 16 at the time of the big hit game is short and the payout of the ball cannot be expected, and neither high probability game nor short time game is given after the big hit game ends. Corresponds to “Daito Bonus”.

  Also, in the reach random number table shown in FIG. 3C, one random number value is acquired from 250 random numbers from “0” to “249” at the time of starting winning, and the acquired reach random number value is “ “0” to “21” is determined to be “reach”, and when the acquired reach random number value is “22” to “249”, it is determined to be “no reach”.

On the other hand, the sub control board 120 performs display control of the image display 11 based on the control command output from the main control board 111.
The display image to be displayed on the image display 11 is an image of a decorative symbol corresponding to the variable symbol special display displayed on the first or second special symbol indicator 21 or 22, a background image corresponding to the game state, a notice There are effect images, reach effect images, jackpot images, and the like. There is also a hold image that displays the number of hold balls. These image data are stored in the CGROM 135 provided on the image control board 131, and the CPU 132 reads out the image data from the CGROM 135 based on the effect command sent from the effect control board 121, and the image display 11. Control to display on the screen. Similarly, the CPU 132 performs control such that sound data is read from the sound data ROM 136 and output from the speaker 105 based on the effect command sent from the effect control board 121.

  Further, the CPU 132 according to the present embodiment executes a refresh operation for injecting charges into the CGROM 135 again during a predetermined period when access for reading image data from the GROM 135 is not performed. For example, in the present embodiment, when the CPU 132 of the image control board 131 receives an effect end command (effect confirmation command) or a customer waiting effect command transmitted from the effect control board 132, the CGROM 135 is refreshed for a predetermined period. Processing is performed.

Hereinafter, an example of processing executed by the game control device in order to realize the operation of the pachinko gaming machine according to the present embodiment will be described.

Hereinafter, various processes executed by the CPU 112 of the main control board 111 in the timer interrupt process will be described.
[First start port SW process]
FIG. 5 is a flowchart showing an example of the first start port SW process executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not the first start port SW13a is ON (S21). If it is determined that the first start port SW13a is ON, the first reserved number U1 of the first start port SW13a is determined. Then, it is determined whether or not it is less than the upper limit of 4 (S22). If the first reserved number U1 is smaller than “4”, “1” is added to the first reserved number U1 (S23).
Next, various random numbers (a jackpot random number, a jackpot symbol random number, a reach random number) are acquired and stored in the RAM 114 (S24). Thereafter, a command for three prize balls is set (S25), and the first start port SW process is terminated.
If it is determined in step S22 that the first reserved number U1 is “4”, a command for three prize balls is set in step S25, and the first start port SW process is terminated. If it is determined in step S21 that the first start port SW13a is not ON, the first start port SW process is terminated.

[Second starter SW processing]
FIG. 6 is a flowchart showing an example of the second starter SW process executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not the second start port SW14a is ON (S26). If it is determined that the second start port SW14a is ON, the second reserved number U2 of the second start port SW14a is determined. Then, it is determined whether or not it is less than the upper limit of 4 (S27). When the second reserved number U2 is smaller than “4”, “1” is added to the second reserved number U2 (S28).
Next, various random numbers (a jackpot random number, a jackpot symbol random number, a reach random number) are acquired and stored in the RAM 114 (S29). Thereafter, a command for three prize balls is set (S30), and the second start port SW process is terminated. If it is determined in step S27 that the second reserved number U2 is “4”, a command for three prize balls is set in step S30, and the second start port SW process is terminated. If it is determined in step S26 that the second start port SW14a is not ON, the second start port SW process is terminated.

[Gate SW processing]
FIG. 7 is a flowchart showing an example of the gate SW process executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not the gate SW 15a is ON (S31). If it is determined that the gate SW 15a is ON, whether or not the holding number G of the gate SW 15a is less than the holding upper limit of four. Is discriminated (S32). If the reserved number G is less than “4”, “1” is added to the reserved number G (S33), a random number is acquired and stored in the RAM 114 (S34), and the gate SW process is terminated. Note that the gate SW process is also ended when the gate SW 15a is not ON or when the reserved number G is "4".

[Special symbol processing]
FIG. 8 is a flowchart showing an example of special symbol processing executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not the jackpot is on (S41). If it is determined that the jackpot is not on, the CPU 112 determines whether or not the special symbols on the first or second special symbol indicators 21 and 22 are changing. Is discriminated (S42). If it is determined that the special symbol is fluctuating, it is next determined whether or not the variable time has ended (S43). If it is determined that the variable time has ended, the first special symbol is changing. Alternatively, a change stop command is set for the second special symbol indicators 21 and 22 (S44), and the change is stopped (S45). Thereafter, the variation time is reset (S46), a stop process (S57) described later is executed, and the special symbol process is terminated. Note that the special symbol processing is also ended when it is determined in step S41 that the jackpot is being hit or when it is determined in step S43 that the variation time has not ended.

On the other hand, if it is determined in step S42 that the special symbol is not changing, it is determined whether or not the second reserved number U2 of the second special symbol is 1 or more (S48). When it is determined that the number is 1 or more, “1” is subtracted from the second reserved number U2 (S49), and then a jackpot determination process is executed (S50).
If it is determined in step S48 that the second reserved number U2 is not 1 or more, it is next determined whether or not the first reserved number U1 is 1 or more (S51). When it is determined that the number is 1 or more, “1” is subtracted from the first hold number U1 (S52), and the process proceeds to the jackpot determination process in step S50.
In step S50, after the big hit determination process is executed, a fluctuation pattern selection process is executed (S53), and a change start command is set in the corresponding first or second special symbol display 21, 22 (S54).
The change start command includes at least information on the determination result of the jackpot of “big hit”, “small hit”, and “losing”, the change time of special symbols (fluctuation pattern), and the mode of production (reach with reach or non-reach effect) ) Is included.
Thereafter, the CPU 112 starts the change of the special symbol (S55). Then, in the subsequent step S56, the measurement of the variation time is started and the special symbol process is ended. If it is determined in step S51 that the first hold number U1 is not 1 or more, a customer waiting setting process is executed (S57). After performing the customer waiting setting process, the special symbol process is terminated.

[Customer waiting setting process]
FIG. 9 is a flowchart showing an example of a customer waiting setting process executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not the customer waiting flag is on (S61). If it is determined that the customer waiting flag is not on, the CPU 112 sets a customer waiting command (S62) and turns on the customer waiting flag. (S63), the customer waiting setting process ends.

[Big hit judgment processing]
FIG. 10 is a flowchart showing an example of the jackpot determination process executed by the CPU 112 of the main control board 111.
In step S71, the CPU 112 determines a jackpot random number. Next, in step S72, it is determined whether or not the jackpot is a jackpot random number (S72), and if it is determined that the jackpot is a jackpot, a jackpot symbol random number is determined (S73).
Next, in step S74, it is determined whether or not the jackpot is a long hit. If it is determined that the jackpot is a long hit, it is determined whether or not the jackpot is a high probability (S75).
If it is determined in step S75 that the probability is high, a symbol per length with high probability is set (S76). If it is determined that the probability is not high, a symbol per length with normal time is set (S77). The jackpot determination process ends.

If it is determined in step S74 that the jackpot is not a long hit, it is determined in step S78 whether or not the jackpot is a high probability.
If it is determined in step S78 that there is a high probability, next, in step S79, it is determined whether or not there is a short time. If there is a short time, a symbol per short with high probability is set (S80), If there is no time saving, a high probability timeless short winning symbol is set (S81), and the jackpot determining process is terminated. If it is determined in step S78 that the probability is not high, a symbol with a short time with a normal time is set (S82), and the jackpot determination process ends.
On the other hand, if it is determined in step S72 that it is not a big hit, it is next determined whether or not it is a small hit (S83). If it is determined that it is a small hit, a small hit symbol is set (S84). If it is determined that it is not a small hit, a lost symbol is set (S85), and the big hit determination process is terminated.

[Processing while stopped]
FIG. 11 is a flowchart illustrating an example of a stop process executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not it is a big hit (S91). If it is determined that the jackpot is a big hit, it is determined whether or not the jackpot is a high probability (S92). If it is determined that the jackpot is a high probability, it is next determined whether or not there is a time reduction ( S93).
If it is determined in step S93 that there is a short time, in step S94, the high probability short time gaming state is set. Thereafter, the jackpot start command is set (S95), the jackpot is started (S96), and the stopped process is terminated.
On the other hand, if it is determined in step S93 that the jackpot is “no time saving”, the game state is set to a high probability timeless gaming state in step S97, and the process proceeds to step S95.
If it is determined in step S92 that the jackpot is not a high probability, the normal time short gaming state is set (S98). Thereafter, the count value J of the hour / hour counter is set to “100” (S99), and the process proceeds to step S95.

If it is determined in step S91 that it is not a big hit, it is determined in step S100 whether or not it is a small hit. If it is a small hit, a small hit start command is issued (S101), and the flow proceeds to step S102. If it is not a small hit, the process proceeds to step S102 without setting a small hit start command.
In step S102, it is determined whether or not the value of the hour / hour counter J is “0”. If the hour / hour counter J is “0”, the hour / middle processing is terminated and the value of the hour / hour counter J is equal to “0”. If it is not “0”, “1” is subtracted from the time reduction count J (S103). Thereafter, it is determined again whether or not the hourly count value J is “0” (S104). If the hourly time count value J is “0” (S104: Yes), the gaming state is set to the normal gaming state. In step S105, the in-stop process is terminated. In step S104, if the time count value J is not "0", the process is terminated without setting the normal gaming state.

[Variation pattern selection processing]
FIG. 12 is a flowchart illustrating an example of a variation pattern selection process executed by the CPU 112 of the main control board 111.
The CPU 112 first determines whether or not the jackpot is based on a jackpot random number (S111). If it is determined that the jackpot is a jackpot, the CPU 112 next determines whether or not the jackpot is a jackpot based on the jackpot symbol. A determination is made (S112). When it is determined that the big hit is a long hit, the long hit table is set in the RAM 114 (S113).
Next, after obtaining a variation pattern random number from the set long hit table and storing it in the RAM 114 (S114), the variation pattern random number is determined (S115), and the variation pattern corresponding to the variation pattern random number is set. In step S116, the variation pattern selection process ends.
On the other hand, if it is determined in step S112 that the jackpot is not a long hit, it is next determined whether or not the jackpot has a short time (S117). (S118), the process proceeds to step S114.

If it is determined in step S117 that the big hit is “no time saving”, the time saving no hit table is set in the RAM 114 (S119), and the process proceeds to step S114.
If it is determined in step S111 that it is not a big hit, the reach random number is determined (S120). If it is determined that the reach is greater than the reach random number, the reach table is set in the RAM 114 (S122), and the reach is not reached. In this case, the loss table is set in the RAM 114 (S123), and the process proceeds to step S114.

[Normal pattern processing]
FIG. 13 is a flowchart showing an example of normal symbol processing executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not the auxiliary game is being played (S131), and if not, the CPU 112 determines whether or not the normal symbol is changing (S132). If it is determined that the normal symbol is changing, it is then determined whether or not the variation time has ended (S133), and if it is determined that the variation time has ended, the variation is stopped (S134).
Next, the variation time is reset (S135), and it is determined whether or not the stop symbol of the normal symbol is a winning symbol (S136). If it is determined that the stop symbol is a winning symbol, an auxiliary game is started (S137), and the process returns to the main process.
If it is determined in step S133 that the variation time has not ended, or if the stop symbol is not a winning symbol in step S136, the process returns to the main process.

On the other hand, if it is determined in step S132 that the normal symbol is not changing, it is determined whether or not the reserved number G of the gate SW 15a is “1” or more (S138). If there is, the reserved number G is decremented by “1” (S139). After that, the random number for the normal symbol is determined (S140). If the random number is a hit, the normal symbol display 23 is set with the winning symbol (S142). Otherwise, the lost symbol is set (S143). ).
Next, it is determined whether or not it is in the short-time gaming state (S144). If it is in the short-time gaming state, the fluctuation time of the normal symbol display 26 is set to 3 seconds (S145), and it is determined that it is not in the short-time gaming state. If so, the fluctuation time of the normal symbol display 26 is set to 29 seconds (S146).
Thereafter, the variation of the normal symbol display 26 is started (S147), the measurement of the variation time is started (S148), and the normal symbol processing is ended. If it is determined in step S138 that the reserved number G is not 1 or more, the normal symbol processing is terminated as it is.

[Large winning prize processing]
FIG. 14 is a flowchart showing an example of a special prize opening process executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not it is a jackpot (S151), and if it is determined that it is a jackpot, it determines whether or not it is a jackpot opening (S152). If it is determined that the jackpot opening is in progress, it is determined whether or not the opening time has elapsed (S153). If it is determined that the opening time has passed, “1” is added to the number of rounds R of the jackpot round (S154), the open / close door of the big winning device is opened, and the big winning opening 16 is opened (S155).
If it is determined in step S151 that the game is not a big hit, or if it is determined in step S153 that the opening time has not elapsed, the big prize opening process is terminated.

Next, it is determined whether or not the opening time of the big winning device has passed (S156). If the opening time has not passed, whether or not the winning number C per round of the big winning device is “9”. It is determined whether or not (S157). When the winning number C is “9”, the open / close door of the large winning device is closed and the large winning opening 16 is closed (S158), and when the winning number C is not “9”, the large winning opening process is terminated. .
On the other hand, if the opening time has elapsed, the big prize opening 16 of the big prize winning device is closed without checking the number C of winning prizes (S158).
After closing the big prize opening 16 of the big prize winning device, the value of the winning number C is set to “0” (S159), and it is determined whether or not the number of big hit rounds is the final round (for example, 15R or 2R) ( S160). If the jackpot round is the final round, ending is started (S161), and if the jackpot round is not the final round, the big prize opening process is terminated.

After starting the ending, the round number R is set to “0” (S162). Thereafter, it is determined whether or not the ending time has passed (S163). If it is determined that the ending time has passed, the jackpot is ended (S164), and the big prize opening process is ended.
On the other hand, if it is determined that the ending time has not elapsed, the big prize opening process is terminated without ending the jackpot.
If it is determined in step S152 that the jackpot opening is not in progress, it is determined whether or not the open / close door of the big winning device is open (S165), and the open / close door of the big winning device is open. If so, the process proceeds to step S156. If the open / close door of the special winning device is not open, it is next determined whether or not it is during an interval (S166). If not, the process proceeds to step S163. If it is during the interval, it is next determined whether or not the interval time has elapsed (S167). If it is determined that the interval time has elapsed, the process proceeds to step S154 and it is determined that the interval time has not elapsed. If so, the special winning opening process is terminated.

[Den Chu processing]
FIG. 15 is a flowchart showing an example of an electric chew process executed by the CPU 112 of the main control board 111.
The CPU 112 determines whether or not the auxiliary game in which the electric chew 14 is operating is in operation (S191), and if it is in the auxiliary game, next determines whether or not the opening is in progress (S192). . If it is determined that the opening time has elapsed, it is determined whether or not the opening time has elapsed (S193). If it is determined that the opening time has elapsed, it is determined whether or not the game is in the short-time gaming state. Is determined (S194), and if it is a short time gaming state, the opening time of the electric chew 14 is set to 3.5 seconds (S195).
If it is determined in step S194 that the game is not in the short-time gaming state, the opening time of the electric chew 14 is set to 0.2 seconds (S196).
Thereafter, the electric chew 14 is opened (S197), and when it is determined that the electric chute 14 opening time has elapsed, the electric chew 14 is closed (S199). Thereafter, the auxiliary game is ended (S200), and the electric-chu process is ended.
If it is determined in step S192 that the opening is not in progress, the process proceeds to step S198. If it is determined in step S191 that the auxiliary game is not being played, if it is determined in step S193 that the opening time has not elapsed, or if it is determined in step S198 that the opening time of the electric chew 14 has not elapsed. Finishes the electric chew process.

[Output processing]
FIG. 16 is a flowchart showing an example of output processing executed by the CPU 112 of the main control board 111.
When the variation start command is set as the output command, the CPU 112 transmits the variation start command in step S211, and when the variation stop command is set as the output command, in step S212, the variation stop command is transmitted. Send. Next, when the customer waiting command is set as the output command, in step S213, the customer waiting command is transmitted.

Next, processing executed by the sub control board will be described.

In this case, the CPU 122 executes a command reception process (S221), an effect button process (S222), and a command transmission process (S223).
Next, an example of main processes executed by the CPU 122 of the effect control board in the timer interrupt process will be described. The processing described below can also be realized by the CPU 122 of the effect control board 121 executing various programs stored in the ROM 123.

[Command reception processing]
FIG. 18 is a flowchart illustrating an example of a command reception process executed by the CPU 122 of the effect control board 121. The process shown in FIG. 18 is also realized by the CPU 122 executing a program stored in the ROM 123.
In this case, the CPU 122 determines whether or not a variation start command has been received (S231), and if it is determined that the variation start command has been received, information about the jackpot determination result included in the variation start command, a special symbol The command analysis such as the fluctuation pattern, presence / absence of reach effect, etc. is performed (S232).
Next, the CPU 122 determines a random number for selecting an effect pattern based on the command analysis result (S233), and performs an effect pattern selection process based on the determination result (S234). After the effect pattern selection process, an effect start command based on the effect pattern is set (S235). If it is determined in step S231 that the change start command has not been received, the process proceeds to step S236 described later.

Next, the CPU 122 determines whether or not a variation stop command has been received (S236). If it is determined that a variation stop command has been received, an effect end command is set (S237). If it is determined in step S236 that the change stop command has not been received, the process proceeds to step S238 without setting the effect end command.
Next, the CPU 122 determines whether or not a customer waiting command has been received (S238), and if it is determined that a customer waiting command has been received, measurement for determining whether or not to execute a customer waiting effect. Is started, the measurement flag is turned on (S239, S240), and the process proceeds to step S242.
On the other hand, if it is determined in step S238 that the customer waiting command has not been received, it is determined whether or not the measurement flag is on (S241). If it is determined that the measurement flag is on, the time is It is determined whether it is up, that is, whether the measurement time has reached a predetermined time (S242). If it is determined in step S242 that the time is up, the measurement flag is turned off (S243), a customer waiting effect command is set (S244), and the command receiving process is terminated. If it is determined in step S241 that the measurement flag is not ON, or if it is determined in step S242 that the time is not up, the command reception process is terminated.

[Command transmission processing]
FIG. 19 is a flowchart showing an example of a command transmission process executed by the CPU 122 of the effect control board 121.
When the production start command is set as an output command, the CPU 122 transmits a variation start command to the image control board 131 (S251), and when the production end command is set as an output command, the CPU 122 sends a variation stop command. The image is transmitted to the image control board 131 (S252). Next, when the customer waiting effect command is set as the output command, the CPU 122 transmits the customer waiting effect command to the image control board 131 (S253).

[LCD effect processing]
FIG. 20 is a flowchart illustrating an example of a liquid crystal effect process executed by the CPU 132 of the image control board 131. Note that the processing described below is realized by the CPU 132 executing a program stored in the ROM 133.
In this case, the CPU 132 repeatedly executes the effect start process (S261), the effect end process (S262), and the customer waiting effect process (S263).

[Direction start processing]
FIG. 21 is a flowchart showing an example of the effect start process executed by the CPU 132 of the image control board 131.
In this case, the CPU 132 determines whether or not an effect start command is received from the effect control board 121 (S264). If it is determined that the production start command has been received, production display is started based on the production start command (S265). Thereafter, the effect start process is terminated.

[Production end processing]
FIG. 22 is a flowchart showing an example of the effect end process executed by the CPU 132 of the image control board 131.
In this case, the CPU 132 determines whether or not an effect end command has been received from the effect control board 121 (S271). If it is determined that the effect end command has been received, the effect display is ended (S272). Thereafter, the CPU 132 performs a refresh operation of the CGROM 135 provided on the image control board 131 (S273).

When the effect end command is received from the effect control board 121 in the image control board 131, the effect determination period in which the effect image displayed on the image display 11 is stopped for a certain period (for example, 0.8 seconds) is set. In this effect determination period, an access operation such as reading image data from the CGROM 135 is not performed.
Therefore, in the present embodiment, the CPU 132 performs the refresh operation of the CGROM 135 using this effect determination period (for example, 0.8 seconds).
However, in this case, since the refresh operation time per one is short, the CGROM 135 cannot be completely refreshed by one refresh operation. Therefore, the CPU 132 in this case performs a refresh operation in a time-sharing manner using a plurality or all of the effect determination periods (for example, 0.8 seconds).

Thus, in the pachinko gaming machine 100 according to the present embodiment, the CGROM 135 that stores the effect image is configured by a NAND flash memory that requires a refresh operation, and the CPU 132 of the image control board 131 does not access the CGROM 135. The refresh process of the CGROM 135 is executed during the fixed period.
Thus, if the CGROM 135 of the image control board 131 is configured by a NAND flash memory, the cost can be reduced as compared with the case of configuring by a conventional NOR flash memory.
Further, since the CPU 132 performs the refresh process during the effect determination period in which access for reading image data to the CGROM 135 is not performed, the effect image displayed on the image display 11 is stopped and the image is disturbed. There is nothing.
Also, if the refresh process is executed during the production confirmation period, there is no need to perform the refresh process when the power is turned on, so the refresh process is automatically performed every time the power is turned on at the time of shipment check in the manufacturing process of pachinko machines. Is also avoided. Therefore, production efficiency is not impaired.
Further, in the present embodiment, the refresh operation is performed in a time-sharing manner using the effect determination period, so the time allotted for one refresh process is as short as 0.8 seconds, for example. Even in some cases, the CGROM 135 can be refreshed.

[Waiting production process]
FIG. 23 is a flowchart illustrating an example of a customer waiting effect process executed by the CPU 132 of the image control board 131.
In this case, the CPU 132 determines whether or not a customer waiting effect command has been received from the effect control board 121 (S281), and when determining that the customer waiting effect command has been received, starts the customer waiting effect display ( S282). Thereafter, the CPU 132 performs a refresh operation of the CGROM 135 provided on the image control board 131 (S283).

When the image control board 131 receives a customer waiting command from the effect control board 121, the CPU 132 of the image control board 131 performs display control for displaying the customer waiting effect image on the image display 11. The customer waiting image display period in which the customer waiting image is displayed is a period in which an access operation of reading image data from the CGROM 135 is not performed.
Therefore, in the present embodiment, the CPU 132 performs the refresh operation of the CGROM 135 by using this waiting image display period.

  Thus, in the pachinko gaming machine 100 according to the present embodiment, a NAND flash memory that requires a refresh operation is used as the CGROM 135 for storing the effect image, and the CPU 132 of the image control board 131 does not access the CGROM 135. A refresh process for refreshing the CGROM 135 is executed during the waiting image display period.

Even in such a configuration, since the CGROM 135 can be configured by a NAND flash memory as described above, the cost can be reduced as compared with the case of configuring by a NOR flash memory.
Further, the effect image displayed on the image display 11 does not stop and the image is not disturbed. Further, since it is not necessary to perform a refresh process when the power is turned on, production efficiency is not impaired.
In addition, compared with the case where the refresh process is executed during the above-described effect determination period, the time allocated to the refresh process per time can be increased, so that the CGROM 135 can be refreshed with a smaller number of processes.

In this embodiment, the case where the refresh operation of the CGROM 135 is performed in both the effect end process and the customer waiting effect process has been described as an example. However, if either the effect end process or the customer wait effect process is performed, Good.
In the present embodiment, the case where a moving image is displayed on the image display 11 has been described as an example. However, for example, when a still image is displayed on the image display 11, the CGROM 135 is displayed while the still image is displayed. Since there is no need to access, the refresh operation of the CGROM 135 may be performed using this period.
As a period for displaying a still image on the image display 11, for example, a jackpot opening period, an ending period, a period during a jackpot round, or the like can be considered.
