Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a pachinko machine that prevents a player from intentionally determining a winning mode.

[Prior art]

Computers are used in recent pachinko machines to electronically control the winning probability of a ball. In such a pachinko machine, in order to determine the hit mode, an event that depends on chance is caused, the hit mode is determined from the event, and the development of a more complicated game is controlled in accordance with the hit mode. ing. Then, for example, a random number table is used to cause an event that depends on the chance. This random number table is rotated after winning and the display of the numerical display is rotated, and the value of the random number table when the stop switch is pressed thereafter is used as the random number to be generated. Then, this random number is displayed on the numerical display and at the same time the mode of hit or miss is determined according to the random number.

[Problems to be Solved by the Invention]

However, since the random number table has a finite number of random numbers and the generated random numbers are displayed on the numerical display, there is a possibility that the random number arrangement of the random number table is deciphered from the numerical values displayed on the numerical display. there were. Then, based on the decoding result, there is a problem that the stop switch is pressed at a timing at which the hit is likely to occur and the hit is intentionally caused. Further, since the display random number is equal to the mode determining random number, there is a problem that the displayed numerical value is limited or biased.

[Means for Solving the Problems]

The present invention, a random number generating means for generating a random number for determining the mode of hitting or out, a deviation numerical value table for generating a numerical value for controlling the display at the time of deviation, and a numerical value for controlling the display at the time of hitting. Has a separate numerical value table for generating, and the mode is determined by a random number generated by a random number generation means,
The display in the out-of-range mode is controlled by the numerical value in the out-of-range numerical value table, and the display in the hit mode is controlled by the numerical value in the hit numerical value table. In the above configuration, the random number generating means for mode determination may be composed of a random number table and address updating means for updating its address, or may be composed of a counter and means for updating the numerical value of the counter. . When the counter is used, for example, when the hit probability is 1 / n, the counter is repeatedly updated from 1 to n as one cycle.

[Action]

When there is a winning in the specific winning opening, the mode is determined by the random number generated by the random number generating means. Then, the display control means sets the numerical value of the address designated by the first address updating means of the deviation numerical value table as the numerical value for display control in the deviation mode, and the numerical value of the hit numerical value table in the hit mode in the hit mode. 2 The numerical value of the address designated by the address updating means is used as the numerical value for display control. As described above, since the numerical value for display control is determined by the random number table which is different from the random number for mode determination, there is no fear that the arrangement of the random number table that determines the mode is deciphered. In addition, the displayed numerical value can be freely controlled.

EXAMPLES The present invention will be described below based on specific examples. FIG. 2 is an external view of the game board 51. The game board 51 is provided with various winning openings, among which 52, 53, 54 are specific winning openings, and when a winning is made in the specific winning openings, a combination operation for determining a winning mode is started. . 56, 59, and 60 are normal winning holes, and 61 and 62 are tulip-type winning holes with an accessory. 63 is a big winning opening that opens and closes according to the hit mode, and a solenoid 41 with an opening / closing door 64 provided inside

Is a 3-digit LED display, and the lamp display 29 is a lamp in which red and blue LEDs are cyclically arranged. When you win a specific prize hole, it will be displayed on the numerical display 27. 3
The digit value fluctuates. Then, when the player presses the stop switch 20 within a predetermined time after winning or when the predetermined time elapses, the changed numerical value stops. The changing numerical value of the numerical display 27 is not related to the rotation of the random number table. When the rotation of the numerical display 27 is stopped, regardless of the fluctuation numerical value at that time, at the time of winning or pressing the stop switch 20, or when the mode is determined, or at any other time, another already The numerical value determined by the numerical table for displaying the hit and the deviation is displayed on the numerical display 27. When the random number for determining the mode is determined, the mode is determined from the value, and the opening time of the opening / closing door 64 of the special winning opening 63 is controlled according to the mode. Further, the game board 51 is provided with various indicators and lamps for displaying the operating state. Reference numeral 30 in the central portion is a memory number indicator for displaying the number of reserved winning balls that have been won in a specific winning opening and for which the winning process is held. 47a-47j
Is an operation lamp that blinks during the combined operation for determining the mode. 43a to 43c are lamps 47 at the time of a big hit.
It is a panic lamp that blinks with a to 47j. Also 45a
45c are V lamps that blink when there is a winning in the V winning opening 63. FIG. 1 is a block diagram showing the electrical configuration of the apparatus of this embodiment. The microcomputer 1 is used as the control device. An external ROM 3 and an external RAM 8 are connected to the microcomputer 1. And
The ROM 3 includes a random number table 31 for determining the hit mode shown in FIG. 6, a deviation numerical value table 32 for determining the numerical value displayed on the numerical display 27 in the deviation mode shown in FIG. A hit numerical value table 33 for determining the numerical value displayed on the numerical value display 27 in the hit mode shown in FIG. 8 is formed. The RAM 8 stores a random number memory 81, a random number table 81, a random number table 32, and a random number table 81, and a random number memory 81 for storing random numbers that change every moment.
The hit number memory 82 and the hit number memory 83 are respectively formed, and in addition, the decision memory 84 for storing the decided random number that decides the hit mode is formed. The fixed memory 84 has a memory of the number of reserved winning balls of a specific winning opening + 1. The random number for each pending winning ball is temporarily determined at the time of winning, and the primary random number is stored in each fixed memory 84, and the stop switch 20 within a predetermined time after the numerical display 27 fluctuates.
When is not pressed, the primarily determined random number is confirmed as the mode-determining random number. When the stop switch 20 is pressed within a predetermined time after the numerical display 27 has changed, the random number generated when the stop switch 20 is pressed is confirmed as the random number for mode determination. On the other hand, a winning detection switch 7 for detecting a winning ball at a specific winning opening, a large winning opening winning detection switch 9 for detecting a winning ball at a large winning opening, a V winning detection switch 11 for detecting a winning ball at a V winning opening, and a stop switch The reference numeral 20 is connected to the microcomputer 1 through a waveform shaping circuit 13 formed of a flip-flop for preventing chattering. The clock generation circuit 17 outputs an external interrupt signal to the INT terminal of the microcomputer 1 via the frequency divider 15. Then, the microcomputer 1 executes the main program shown in FIG. 4 in synchronization with the external interrupt signal. The timing signal output from the timing signal generation circuit 18 is input to the RST1 terminal of the microcomputer 1, and the random number generation program shown in FIG. 5 is started in synchronization with the timing signal. Further, reference numeral 21 is a power supply circuit, the signal of the start switch 23 is input to the reset signal generation circuit 19, and the reset signal which is the output signal thereof is input to the RST2 terminal of the microcomputer 1. , The initial program shown in FIG. 3 is started. A display drive circuit 25, a display selection circuit 28, and a driver 39 are connected to each output port of the microcomputer 1. The display drive circuit 25 and the display selection circuit 28 include a numerical display 27, a lamp display 29, and a stored number display 30 described above.
Are connected. These displays are dynamically driven by outputting the selection data and the display data from the microcomputer 1 at a constant cycle. That is, each display unit is selected by the display selection circuit 28 and displayed according to the output signal of the display drive circuit 25 at that time. The driver 39 drives the solenoid 41 in response to a signal from the microcomputer 1 to control the lighting operation of the panic lamp 43, the V lamp 45, and the operation lamp 47. Next, the operation of the pachinko machine having such a configuration will be described based on a flowchart showing a processing procedure of the microcomputer 1. (1) Initial setting when power is turned on When the start switch 23 is turned on, the microcomputer 1 is supplied with power and the reset signal generation circuit 19 outputs the reset signal S4 to the RST2 terminal. Then, CPU1
The processing shown in FIG. 3 is executed. That is, set the 3-digit numerical registers X1, X2, X3 displayed on the numerical display 27 to the initial values,
The display lamp register L which stores the lighting lamp of the lamp display 29 is set to an initial value. Further, the winning prize ball counter C that counts the number of pending winning prize balls that have been won in a specific winning hole is set to zero, and the large winning hole prize counter G that counts the number of winning balls to the special winning hole is set to zero. A V winning ball counter A, which stores the presence or absence of a pending winning ball to the V winning opening, is initially set to zero. Further, the state register F storing the control state is initialized to zero, the mode register R storing the mode is initialized to zero, and the timers T1, T2, T3 are initialized to zero. Then, the tens digit of the random number stored in the random number memory 81 is set to the initial value 1, and the address I of the random number table 31 for determining the hundreds digit and the ones digit of the random number from the random number table 31. Is set to an initial value of 1. Also, the outlier numerical table 32
Address J and the address K of the hit number table 33 are
Each is set to an initial value of 1. (2) Rotation of random number table and numerical value table In parallel with the processing of the main program of FIG. 4, the random number generating program shown in FIG. 5 is started in synchronization with the timing signal input from the RST1 terminal. That is, step 200
Then, the numerical value stored in the address I is read from the random number table 31, and the numerical value is stored in the hundreds digit and the ones digit of the random number memory 81. Then, in the next step 202, the address I
Is determined to be the final value of the address of the random number table 31, and if it is not the final value, the address I
Is updated by 1, and this random number generation program is terminated. If the value of the address I is determined to be the final value in step 202, the process proceeds to step 206 and the address I
Is set to the initial value 1, and in the next step 208, the numerical value of the tens digit of the random number is incremented by 1. In this way, random numbers for mode determination are generated in the random number memory 81 at any time after the pachinko machine is reset. The random number generation speed at this time is determined by the timing signal output from the timing signal generation circuit 18. Similarly, in step 210, the numerical value stored in the address J is read from the deviation numerical value table 32 for display in the deviation mode, and the numerical value is stored in each of the three digits of the deviation numerical value memory 82. Then, in the next step 212, it is judged whether or not the value of the address J is the final value of the address in the numerical value table 32, and if it is not the final value, the address J is determined in the step 214.
Is updated by 1 and the present random number generation program ends, and when the value of the address J is determined to be the final value in step 212, the process proceeds to step 216 and the address J is set to 1 as the initial value.
Is set to. Further, similarly, in steps 218 to 224, the address K of the hit numerical value table 33 for display in the hit mode is displayed.
The numerical value stored in the table is stored in the hit numerical value memory 83 as a hit mode display numerical value. When the address K is updated and the final address of the hit numerical value table 33 is exceeded, the initial value 1 is set. In this way, each time a tamming signal is input, the out-of-range numerical value memory 82 stores the numerical value for display in the out-of-range mode, and the hit numerical value memory 83 stores the numerical value for display in the hitting mode. Incidentally, the address of the table may be stored in each memory, and the numerical value of the address may be read at the time of display. (3) Main program After the initial setting, the CPU 1 executes the main program of FIG. 4 every time the external interrupt signal output from the frequency divider 15 is input. In step 100, the timer is updated, and in step 102, the status signals S1, S2, S3 of the switch group are
Is loaded. These status signals are composed of negative logic and indicate that the switch is in the ON state when the signal is at a low level and a winning ball is detected. Therefore, in steps 104, 110 and 114, the trailing edge of each state signal is detected, and only at that time, the counters C, G and A are updated by 1. However, the number of winning prize balls that are suspended is 10
At 6, I try to count only up to 4. Then, when the winning in the specific winning opening is detected, the determination in step 104 is YES, and when the number of the reserved winning balls is smaller than 4 in step 106, the winning ball counter C is updated by 1 in step 108. In step 109, the value of the random number memory 81 at that time is stored in the definite memory M (C) 83.
That is, when the winning of the specific winning opening is detected in the state where there are no reserved winning balls, the winning ball counter C becomes 1, and the value of the random number memory 81 at that time is stored in the fixed memory M (1).
Further, when the prize winning ball counter C is 1 or more and a prize is further won in the specific prize opening, the prize winning ball becomes a reserved prize winning ball, and the prize winning ball counter C is incremented by one. Then, the value of the random number memory 81 at the time of winning is stored in the fixed memory M (C) corresponding to the reserved winning ball. In this way, the primary random number for determining the winning mode is determined when the specific winning opening is won. The following steps 118 to 166 are processing steps according to each state. (A) Processing when no winning ball is present When no winning ball is present, that is, when the counter C is 0, the processing of steps 100 to 124,170 is performed, whereby a numerical display, a lamp display, Each lamp group performs a predetermined display. (B) Combination operation processing In step 124, the value of the counter C is determined, and when a winning is detected, the value of the counter C is decremented by 1, the register F is set to 1 to indicate the combination operation state, and the timer T1 is set to a predetermined value. Set to the value (steps 124 to 128). And step 12
As the winning ball counter C is decremented in 9, the contents of the fixed memory M (C) are moved up one by one and updated. Next, in step 130, it is determined whether or not the timer T1 has timed out.If it is determined that the time has not expired, then in step 131 it is determined whether or not the stop switch 20 has been pressed, and the stop switch 20 is pressed. If so, the process proceeds to step 132, the value of the random number memory 81 at that time is stored in the finalized memo M (0), and the random number temporarily determined in the finalized memory M (0) is finally finalized. It is rewritten by the generated random number. When it is determined in step 130 that the timer T1 has timed out, the process proceeds to step 134, and the primary random number stored in the finalization memory M (0) is finalized as the final random number. Then, in step 130, which is executed when a predetermined time has elapsed or the stop switch 20 is pressed, the fixed memory M
The hit mode is determined from the value (0), and the hit mode is set in the mode register R. Next, the routine proceeds to step 135, where it is judged from the contents of the mode register R whether or not it is the disengagement mode. The value of each digit of the stored out-of-range numeric memory 82 is displayed in the numeric display register X1, X
By setting to 2, X3, the numerical value display 27 displays the numerical value for display at the time of the deviation stored in the deviation numerical value memory 82. If it is determined that it is not in the out-of-range mode, the process proceeds to step 137, and the value of each digit of the hit value memory 83 that stores the display value in the hit mode is set in the value display registers X1, X2, X3. As a result, the numerical value display 27 displays the numerical value for display in the hit mode stored in the hit numerical value memory 83. In this way, the numerical display 27 displays the numerical values for display generated by the out-of-display numerical value table and the hit numerical value table which are different from the random number table for determining the mode. The processing of steps 100 to 118, 130, 131, 170 is repeated until the stop switch 20 is pressed or the time is up. The values set in the mode register R are 0, 1 is a small hit, 2 is a medium hit, and 3 is a big hit. When the player is out of position, the register F is set to 0, and the process goes to the next winning ball determination cycle. (C) Processing when hitting When the judgment result of step 139 is hitting, the time is set in the timer T2 in step 144 according to the mode. Then, the above-described processing is performed until the timer T2 is determined to have timed up in step 146. As a result, the special winning opening is opened for a predetermined time, and the lamp group is displayed as a panic state. At this time, if it is determined in step 148 that the number of winning balls to the special winning opening is 10, the process similar to the time-up is performed even before the time-up. That is, in step 150, the counter G is set to 0 and the register R is set to 0. (D) Processing when V winning ball is present When the V winning ball is present when the special winning opening is open, that is,
When the counter A is 1 (step 156), the value of the register F is set to 3 in step 158 to indicate the generation of the continuing right. Then, in step 162, the timer T3 is set to a predetermined time, and in step 164 it is determined whether the time is up. This process is to give a certain delay until the special winning opening is subsequently opened. After this, step 166
To set the register R to the value 3 which indicates a big hit, and step 14
Go to 2 and perform the above-mentioned hitting process. However, the continuation right is adjusted in step 152 so that it does not occur more than 10 times. In the above-mentioned embodiment, the numerical value is displayed on the numerical display 27, but it may be a design or the like. Also, when changing the displayed numerical value according to multiple types of modes such as big hit, medium hit, small hit, etc., prepare multiple kinds of display numerical value tables corresponding to various hit modes, depending on each hit mode. Numerical display based on the numerical values generated by the numerical table
The display of 27 may be controlled. Further, the outlier numerical value table and the hit numerical value table may be a random number table or a regular table. Further, the random number generating means may be constituted by a counter and means for sequentially updating the numerical value of the counter in addition to the random number table. Also, the timing for determining the random number for determining the winning mode is
As described above, the determination may be made at the time of winning or when the stop switch 20 is pressed, and at another timing determined according to the winning. Further, although the address is changed in synchronization with the random number table, the outlier numerical value table, and the hit numerical value table with the same timing signal, they may be changed at different timings. Further, the generation of random numbers as described above is not limited to a pachinko machine, but can be used for a game machine such as a throttle machine that causes other randomness.

【The invention's effect】

The present invention provides a random number generating means for generating a random number for mode determination, a deviation numerical value table for determining display numerical values for controlling the display in the deviation mode, and a display numerical value for controlling the display in the hit mode. Since a random number table for determining numerical values is provided and the random numbers for mode determination and the numerical values for display are generated by different means, the random number generation order of the random number generation means for mode determination can be predicted from the display. Never. Therefore, the hit mode is not intentionally generated. Further, since the numerical table for display is prepared separately, it becomes possible to freely and widely change the numerical value for display control in the detach mode or the hit mode, and the degree of freedom of display is improved. Further, when the random number generating means is composed of a random number table, by exchanging the random number tables, it is possible to easily change only the probability of occurrence of the hit mode without changing the display combination.
