Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine which provides a game advantageous to a player when a specific symbol is displayed on a screen of a game board. More specifically, the present invention relates to control for displaying an image on a screen. 2. Description of the Related Art As gaming machines in recent years, so-called fever machines, gaming machines having various kinds of game contents called right goods or arrangements have been widely used. When the display state of the variable display device is statically displayed after the display state of the variable display device fluctuates, the fever machine performs a so-called reach display in which, for example, the two-digit display part of the three-digit display part is the same symbol, and thereafter, the remaining display is performed. The same combination of symbols as the other display units on the display unit, specifically, “7,
When a specific combination of three digits such as "7, 7" is displayed, a so-called big hit state is opened so as to open a special winning opening called an attacker. The special winning opening is closed once a predetermined number of gaming balls have won or a predetermined time has elapsed, but if the gaming balls have passed through the specific area formed in the special winning opening during the opening, the special winning opening is re-entered. It is configured to open and repeat the opening and closing operations up to 16 times. In this big hit state, a large amount of game balls can be made to win the big winning opening. Normally, one opening of the special winning opening allows 10 game balls to enter the special winning opening, and this is repeated 16 times.
60 game balls can be won. In general, 15 game balls are paid out as prize balls for one winning game ball. Therefore, when a big hit state occurs, a maximum of 2400 (= 10 × 16 ×
15) The game balls are paid out as prize balls. The control for displaying the same three-digit specific symbol on the variable display device is generally performed as follows. The control of the pachinko machine is roughly divided into a main control board for controlling a game on the game board, an image control board (symbol display device) for displaying an image on a screen on the game board, and paying out a prize ball to a player. And the like, a launch control platform for controlling the firing handle, and the like. In the main control board, a predetermined time (usually 2 ms to 2.5 m
s) Interruption processing is executed, and various controls such as update processing of winning / decreasing random numbers used for determining a jackpot, jackpot symbol random numbers used for determining a jackpot symbol, and outlier symbol random numbers used for determining an outlier symbol are performed. Is configured to end within this interrupt time. In the success / failure decision random number update process, the value is incremented by one only once in the interrupt process, and 225 numerical values from 0 to 224 are repeatedly generated within a certain range. The out-of-designs are composed of a left-out design, a middle-out design, and a right-out design, and for example, 15 numerical values from 0 to 14 are repeatedly generated. Missing left symbols are incremented by +1 during interrupt processing, and missing symbols are 14 missing symbols.
+1 is added when the symbol is updated from 0 to 0, and similarly, the off-right symbol is incremented by 1 when the losing symbol is updated from 14 to 0. Until the time elapses, the same update processing is executed to change the value. These random numbers are randomly selected when a game ball fired on the game board surface enters a specific winning opening (ball entrance). Even if the game balls are fired at substantially the same timing (usually 100 balls per minute), the fired game balls are given a change in the flow speed or flow direction by obstacles such as nails on the board, and the game balls are specifically won. The timing at which the ball enters the mouth is irregular, and the various random numbers act literally as random numbers. [0004] When a game ball enters a specific winning opening, a winning / failing random number, a jackpot symbol random number, and a lost symbol random number are selected, and data corresponding to the selected value is transmitted to the image control board. In the image control board, a special symbol for notifying the player of the result of the determination based on the data received from the main control board is displayed on the screen for a predetermined time (usually 5.0 ms to 29.9 m).
s) Control to perform static display after performing variable display. That is, every time a game ball enters the specific winning opening, the special symbol fluctuates on the image control board, and the result is displayed. However, the probability of a jackpot is generally 1/200 to 1/3
It is rare that a jackpot is displayed on the screen within the range of 60. For this reason, a trick display such as displaying a jackpot display to make the player feel nervous or losing to a jackpot or performing a false jackpot display, or performing a false jackpot display by displaying a false jackpot to perform a jackpot display is performed. Also, control is performed so that the player does not feel bored. [0005] However, there is a limit to the trick display, and even if the trick display appears to be a big hit, if it finally comes off, the reliability of the trick display will be doubted. In order to solve this, it is conceivable to increase the probability of jackpots, but this is not preferable in terms of pachinko hall management. The ball game machine of the present invention has been made for the purpose of solving this problem. According to the present invention, a random number is selected based on the behavior of a game ball fired on a game board, and the selected random number value is a predetermined random number. A main control board that executes a special game advantageous to the player due to the value, and receives data based on the selection result of the random number from the main control board, and according to the received data, a special game notification A video control board that displays the pattern on the screen,
In the ball game machine at least equipped with, communication from the main control board to the video control board is only one direction,
The video control board is configured to be unable to communicate with the main control board in the previous period, and in the video control board, measuring means for measuring an elapsed time from when the special game occurs or when the special game ends, and measurement by the measuring means Background display means for displaying an image based on the result as the background of the symbol. It is preferable that the background display means develops a story based on the measurement result as the elapsed time from the end of the special game increases. It is preferable that the measuring means of the video control base measures, based on the received data, an elapsed time from when the special game occurs or when the special game ends. Here, the measuring means may be a means for measuring the elapsed time from when a special game has occurred or has ended based on data transmitted from the main base, and is provided in the video control base. I have. The background display means may be any means that displays an image based on the measurement result as the background of the symbol, and the background is changed in a story based on the measurement result every time the elapsed time after the end of the special game is increased. Alternatively, a configuration in which the background is simply switched may be used. According to the first aspect of the present invention, the measuring means of the video control board measures the elapsed time from when the special game has occurred or has ended, and according to the measurement result, the background of the symbol for the special game notification. Is changed. As a result, the image according to the elapsed time of the special game can be displayed on the screen on the video control base without increasing the processing on the main control base and without changing the transmission data on the main control base. it can. A specific example of a ball game machine according to an embodiment of the present invention will be described. FIG. 1 is a schematic front view of a pachinko machine 10 as a gaming machine of the present invention. This pachinko machine 10 is configured as a so-called fever machine,

It is configured so that the number of the left winning opening 17, the right winning opening 18, the lower left winning opening 19 and the lower right winning opening 20 is 10, and the large winning opening 21 is 15. The passing openings 15 and 16 are for displaying a normal symbol on a normal symbol display device (not shown) in a variable manner, and a winning symbol, for example, “7” or the like is used as a normal symbol with a certain probability (in the present embodiment, 1/10). When displayed, the ordinary electric accessory 13 is expanded and opened for about 5 seconds. [0010] When the special winning symbol 21 such as "777" is displayed on the special symbol display device 12 with a certain probability (1/220 in the present embodiment), the special winning symbol 21 becomes approximately 30.
Seconds or until 10 game balls are won. At this time, when the game ball passes through the specific area provided in the special winning opening, it is closed once and then opened again, and the opening operation is repeated up to 16 times including the first time.

The pachinko machine 1 according to the present embodiment having the above configuration.
0, the special symbol control board 54 displays a symbol on the special symbol display device 12 for a predetermined time if a game ball fired by the player centering on the game control board 30 wins the ordinary electric accessory 13 which is the first kind starting port. After the fluctuation display, the game ball is usually a motorized accessory 1
The symbol corresponding to the value of the random number selected according to the timing when winning the third is statically displayed. At this time, if the symbol that has been statically displayed is a specific symbol, for example, a specific symbol such as “777”, a process of opening the special winning opening 21 a predetermined number of times as a known “big hit” is executed. The process of variably displaying a special symbol on the special symbol control board 54 is executed as follows. The CPU 70 of the game control board 30 determines whether or not a big hit (whether or not the condition device operates) according to the value of the hit / fail decision random number RD selected when the game ball enters the first type starting port 13. Then, based on this determination, predetermined data is transmitted to the special symbol control board 54. Specifically, a flag indicating that the condition device has not been activated, data indicating the left, middle, and right special symbols, data indicating the display position of each special symbol, and the like are periodically transmitted every 2 ms as 10 to 12 bytes of data. I do. At the time of a big hit, a flag indicating whether or not the vehicle passes through a specific area in the special winning opening 21, data on the number of times of opening of the special winning opening 21, data indicating left, middle and right special symbols as a big hit symbol, and a display position of each special symbol Is periodically transmitted every 10 ms as data of 10 to 12 bytes. Based on the data transmitted from the game control board 30, the CPU 80 of the special symbol control board 54
The processing for variably displaying the left, middle and right special symbols on the screen according to the timing chart shown in FIG. Points P <b> 1 to P <b> 19 shown in the figure indicate change points such as the changing speed of each special symbol. In this specific example, since the game control board 30 is configured to regularly transmit data at regular intervals, it is impossible for the special symbol control board 54 to receive data in a timely manner due to noise or the like. Even in such a case, there is an effect that the problem is that the image is only temporarily disturbed, but a so-called intelligent method of transmitting data at a time corresponding to the change of points P1 to P19 in the figure is adopted. Is also good. It is needless to say that the timing chart shown in FIG. 7 is one variation pattern of a special symbol, which is different at the time of so-called reach, at the time of so-called hold storage, or at the time of a big hit. This variation pattern is nothing but an example in which a special symbol is variably displayed when one game ball enters the first type starting port 13. Next, the processing of displaying the background and characters displayed on the screen by the special symbol control board 54 will be described with reference to the flowcharts shown in FIGS. 8 is executed at the display end timings P17 to P19 shown in FIG.
First, it is determined whether or not the special symbol displayed in a stationary manner is a big hit (step S100). If an affirmative determination is made that the big hit is not displayed, the value of the number of times of off-counter CT is incremented by one (step S110). Is determined, the value of the number-of-disengagement counter CT is cleared to zero (step S120). The value of the counter CT is cleared to zero when the power is turned on. When the above processing is executed, a "background change routine" shown in FIG. 9 is subsequently executed. Here, it is determined whether the value of the counter CT is less than 100, 100 or more, less than 200, 200 or more, less than 300, 300 or more, less than 400, or 400 or more (step S2).
00 to S240). When the value of the counter CT is less than 100,
A spring landscape is displayed as a background display of each special symbol (step S250). The value of the counter CT is 100 or more and 20
If it is less than 0, a summer landscape is displayed as a background display of each special symbol (step S260). When the value of the counter CT is 200 or more and less than 300, autumn scenery is displayed as a background display of each special symbol (step S270).
If the value of the counter CT is 300 or more and less than 400, a winter landscape is displayed as a background display of each special symbol (step S280). If the value of the counter CT is 400 or more, a landscape of paradise is displayed as a background display of each special symbol (step S290). Step S250-S
After the process of 290, the process returns to the return. According to this specific example, the background of the special symbol is changed in accordance with the number of hits of the big hit, so that it is possible to change the visual sense of the player and to alleviate the boring feeling that the big hit does not come. To play. Also, in general, the greater the number of times of departure, the greater the expectation that the next big hit will come. Also have. Further, since the number of misses is counted on the special symbol control board 54 side, there is an extremely excellent effect that the processing load on the game control board 30 can be reduced. In this specific example, the value of the counter CT is 400
In the above case, the background of the paradise was set.
The value of T may be cleared to zero and the background may be displayed repeatedly in the order of spring → summer → autumn → winter → spring. Further, if the game ball is not fired for a predetermined time (specifically, about 5 minutes) or more, the value of the counter CT may be cleared to zero assuming that the player has left the table. Further, the counter C
The configuration may be such that the number of times of determination of the value of T is further increased and sights of all over Japan or the world are displayed as a background, or a cartoon character may be displayed as a background, or a face of a celebrity is displayed as a background. Good, and the story may be developed as the number of judgments increases. According to the first aspect of the present invention, there is no special processing on the video control board side without increasing the processing on the main control board side and without changing the transmission data on the main control board side. While displaying an image on the screen according to the elapsed time of the game,
It is possible to give a change to the image viewed by the player, and to achieve an extremely excellent effect that the interest of the game can be further enhanced.
