Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a pachinko machine in which the occurrence probability of a hit mode is variably controlled.

[Prior art]

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

[Problems to be solved by the invention]

However, the existence probability of the winning numerical value in the random number table is fixed when the random number table is determined,
The probability of occurrence could not be changed arbitrarily.
Also, since the random number for display is equal to the random number for mode determination,
The displayed values were limited or biased. Further, in order to change the hit probability, it is necessary to newly design a random number table and replace it with the random number table, which has been difficult.

[Means for Solving the Problems]

The present invention provides a mode numerical value generating means for generating a numerical value for determining a hit or an out-of-mode, a probability control means for varying a probability of occurrence of a numerical value generated by the mode numerical value generating means, and a display at the time of the off-state. An outlier numerical value generating means for generating a numerical value to be controlled, a hit numerical value generating means for generating a numerical value for controlling the display of a hit time, a mode determining means for determining a mode, and a display in an outlier mode by the outlier numerical value generating means. The display in the hit mode is controlled by numerical values, and the display in the hit mode is controlled by numerical values by the hit numerical value generating means. In the above configuration, the mode numerical value generating means for mode determination is set to one at a fixed or fluctuating time interval from the initial value.
The probability control means can variably set the probability of occurrence of the hit value, and comprises a counter which operates to return to the initial value again when the value exceeds the final value. It is constituted by means for changing the value. For example, when the hit probability is 1 / n, the counter is repeatedly updated as one cycle from 1 to n, and by changing this final value n, the occurrence probability of a specific numerical value generated by the kautan is changed. Can be.

[Action]

When there is a winning in the specific winning opening, the mode is determined by the numerical value generated by the mode numerical value generating means. Then, the occurrence probability of the numerical value can be changed by the probability control means. Further, the display control means sets the numerical value generated by the outlier numerical value generating means in the case of the out-of-off mode, and the numerical value generated by the hit numerical value generating means in the case of the hit mode, as the numerical value for display control. . As described above, since the numerical value for display control is determined by means different from the numerical value for mode determination, the probability of occurrence of the numerical value used for display is kept constant, and only the probability of occurrence of the numerical value for mode determination is kept. Can be changed. The probability can be changed by manual setting or automatically changed by a function such as time of day, day of the week, weather, and the like.

Note that the fluctuating numerical value of the numerical display 27 is irrelevant to the numerical value for mode determination. When the rotation of the numerical display 27 is stopped, regardless of the fluctuation value at that time, at the time of winning, when the stop switch 20 is pressed, or when the mode is determined, or at any other time, another time has already been set. The numerical value determined by the numerical value table for displaying the hit / miss is displayed on the numerical display 27. When the numerical value 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 in accordance with the mode.

The microcomputer 1 is used for the control device. An external ROM 3 and an external RAM 8 are connected to the microcomputer 1. The ROM 3 has a numeric display in the off mode shown in FIG.
Outlier value table 31 for determining the value to be displayed in 27
And a hit numerical value table 32 for determining a numerical value to be displayed on the numerical value display 27 in the hit mode shown in FIG. The RAM 8 is formed with a mode determination counter 81, an outlier numerical memory 82 and a hit numerical memory 83 in which numerical values that change every moment by the outlier numerical table 31 and the hit numerical table 32 are formed, respectively. Confirmation memory 84 for storing the decided numerical value to be decided
Are formed. The determined memory 84 has a memory of the number of the reserved winning balls of the specific winning opening + 1. The numerical value for mode determination for each pending prize ball is temporarily determined at the time of winning, the primary numerical value is stored in each determination memory 84, and the stop switch 20 is set within a predetermined time after the numerical display 27 changes.
Is not pressed, the temporarily determined numerical value is determined as a numerical value for mode determination. If the stop switch 20 is pressed within a predetermined time after the change of the numerical display 27, the numerical value generated when the stop switch 20 is pressed is determined as the mode determination numerical value. The DIP switch 4 is connected to the microcomputer 1,
The dip switch 4 is for setting the probability of occurrence of the hit mode. On the other hand, a winning detection switch 7 for detecting a winning ball in a specific winning opening, a special winning opening winning switch 9 for detecting a winning ball in a special winning opening, a V winning detection switch 11 for detecting a winning ball in a V winning opening, and a stop switch. Reference numeral 20 is connected to the microcomputer 1 via a waveform shaping circuit 13 composed 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 numerical value generation program shown in FIG. 5 is started in synchronization with the timing signal. 21 is a power supply circuit, and the signal of the start switch 23 is
The reset signal which is input to the reset signal generating circuit 19 and which is the output signal is input to the RST2 terminal of the microcomputer 1, and the reset signal starts the initial program shown in FIG. 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 the numerical display 27, the lamp display 29, and the stored number display described above.
30 is connected. These displays are dynamically driven by outputting selected data and display data from the microcomputer 1 at regular intervals. That is, each display unit is selected by the display selection circuit 28, and is displayed according to the output signal of the display drive circuit 25 at that time. The driver 39 drives the solenoid 41 according to a signal from the microcomputer 1 and controls 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 at power-on When the start switch 23 is turned on, power is supplied to the microcomputer 1 and the reset signal generation circuit 19
Outputs reset signal S4 to RST2 pin. Then CPU1
Executes the processing shown in FIG. That is, the numerical display 27
Is set to the initial value, and the display lamp register L storing the lighting lamp of the lamp display 29 is set to the initial value. Also, the winning prize ball counter C for counting the number of pending prize balls winning and holding the specific winning opening is set to zero, and the special winning opening prize counter G for counting the number of winning balls to the special winning opening is set to zero. A V winning ball counter A that stores the presence or absence of a winning ball in the V winning port is initially set to zero. 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 numerical value I of the mode determination counter 81 is set to the initial value of 1. Further, the address J of the outlier numerical value table 31 and the address K of the hit numerical value table 32 are each set to an initial value of 1. (2) Increment of the mode determination counter and rotation of the numerical value table In parallel with the processing of the main program of FIG. 4, the numerical value generating program shown in FIG. 5 is started in synchronization with the timing signal input from the RST1 terminal. You. That is, step 20
When the value is set to 0, the numerical value set in the dip switch 4 of the probability setting device is read out by the mode determination counter 81 as the final value of the numerical value incremented. In the next step 202, it is determined whether or not the value of the numerical value I of the mode determination counter 81 is equal to or more than the final value read in step 200. If not, in step 204, the numerical value I of the mode determination counter 81 is set to 1 Only be advanced. If it is determined in step 202 that the value of the numerical value I of the mode determination counter 81 is equal to or greater than the final value,
Proceeding to step 206, the numerical value I of the mode determination counter 81
Is set to an initial value of 1. In this way, the mode determination counter 81 generates a numerical value for mode determination that is sequentially advanced in the range from the initial value 1 to the final value at an arbitrary time after the pachinko machine is reset. The generation speed of the numerical value at this time is determined by the timing signal output from the timing signal generation circuit 18. Similarly, in step 208, the numerical value stored in the address J is read from the numerical value table 31 for display in the deviating mode, and the numerical value is stored in each of the three digits of the deviating numerical value memory 82. Then, in the next step 210, it is determined whether or not the value of the address J is out of range and the final value of the address in the numerical value table 31. If not, the address J is updated by 1 in step 212. In step 210, the address J
Is determined to be the final value, the process proceeds to step 214, where the address J is set to the initial value of 1. Further, similarly, in steps 216 to 222,
The value stored at the address K in the hit value table 32 for display in the hit mode is stored as a hit mode display value in the hit value memory 83, and when the address K is updated and the last address of the hit value table 32 is exceeded. Processing for setting the initial value 1 is performed. In this way, every time a tamping signal is input,
The outlier value memory 82 stores display values in the out-of-off mode, and the hit value memory 83 stores display values in the hit mode. It is also possible to store the address of the table in each memory, and to read the numerical value of the table at the address at the time of display. (3) Main Program After the initial setting, the CPU 1 executes the main program of FIG. 4 every time an external interrupt signal output from the frequency divider 15 is input. In step 100, the timer is updated. In step 102, the state signals S1, S2, S
3 is read. These status signals are configured by negative logic, and indicate that the switch is on when the signal is at a low level, and that a winning ball is detected. Therefore, at steps 104, 110, and 114, the falling of each state signal is detected, and only at that time, each of the counters C, G, and A is updated by one. However, the number of prize balls held is determined by Step 10
In step 6, only counting up to 4 is performed. Then, when a winning in the specific winning opening is detected, the determination in step 104 becomes YES, and when the number of pending 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 mode determination counter 81 at that time is stored in the determination memory M (C) 84. That is, when a winning in the specific winning opening is detected in a state where there is no pending winning ball, the winning ball counter C becomes 1, and
The value of the mode determination counter 81 at that time is stored in the determined memory M
It is stored in (1). Further, when the winning prize ball counter C is 1 or more, if the player wins a specific winning opening, the winning prize ball becomes a reserved prize ball and the prize ball counter C is incremented by one. Then, the value of the mode determination counter 81 at the time of winning is stored in the determination memory M (C) corresponding to the reserved winning ball. In this way, when a specific winning opening is won, the primary numerical value for determining the hit mode is determined. The following steps 118 to 166 are processing steps according to each state. (A) Processing when there is no winning ball When there is no winning ball, that is, when the counter C is 0, the processing of steps 100 to 124 and 170 is performed, whereby the numerical display, the lamp display, Each lamp group performs a predetermined display. (B) Combination operation processing In step 124, the value of the counter C is determined. 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. A value is set (steps 124 to 128). And step
As the winning ball counter C is decremented at 129, the contents of the determined memory M (C) 84 are incremented and updated one by one. 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, it is determined in step 131 whether or not the stop switch 20 has been pressed, and the stop switch 20 has been pressed. If so, the process proceeds to step 132, where the mode determination counter 81 at that time is set.
Is stored in the determination memory M (0), and the determination memory M
The numerical value temporarily determined in (0) is rewritten by the finally determined numerical value. If it is determined in step 130 that the timer T1 has expired, the process proceeds to step 134, where the determination memory M (0)
Is determined as a final mode decision value. Then, in step 134, which is executed when the predetermined time has elapsed or when the stop switch 20 is pressed, the finalized memory M
By determining whether the value of (0) is a hit value,
The hit or miss mode is determined, and the mode is set in the mode register R. Next, the routine proceeds to step 135, where it is determined whether or not the mode is the out-of-mode from the contents of the mode register R.
6 and the values of each digit of the outlier value memory 82 storing the display values in the outlier mode are stored in the numerical value display registers X1, X2, X3.
As a result, the numerical value display 27 displays the numerical value for display in the off mode stored in the outlier numerical value memory 82. If it is determined that the mode is not the out-of-off mode, the process proceeds to step 137, and the value of each digit of the hit value memory 83, which 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 display numerical value in the hit mode stored in the hit numerical value memory 83. In this way, the numerical value display 27 displays the out-of-display numerical value table and the display numerical value generated by the hit numerical value table, which are different from the numerical value generating means for determining the mode. Until the stop switch 20 is pressed or the time is up, the processing of steps 100 to 118, 130, 131, and 170 is repeated. The value set in the mode register R is 0, 1 is a small hit, 2 is a medium hit, and 3 is a big hit. When it comes off,
The register F is set to 0, and the process proceeds to the cycle for determining the next winning ball. (C) Processing at the time of a hit If the result of the determination at the step 139 is a hit, a time is set to the timer T2 at a step 144 according to the mode.
Then, the above-described processing is performed until the timer T2 determines that the time is up in step 146. As a result, the special winning opening is opened for a predetermined time, and the lamp group is displayed to indicate a panic state. At this time, if it is determined in step 148 that the number of winning balls in the special winning opening is 10, the same processing as 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 a V Win Ball Exists If the V win ball exists when the special winning opening is open, that is, if the counter A is 1 (step 156), step 1 is executed.
At 58, the value of the register F is set to 3 to indicate the generation of the continuation right. Then, in a step 162, the timer T3 is set to a predetermined time, and in a step 164, time-up is determined. This process is for giving a certain delay until the special winning opening is subsequently opened. After this, step 16
In step 6, register R is set to a value 3 indicating a big hit, and step 1
The process proceeds to 42 to perform the above-mentioned hit processing. However, the continuation right is adjusted in step 152 so that it does not occur more than ten times. In the above embodiment, when the probability of occurrence of the hit mode is changed, the numerical value set in the dip switch 4 may be changed. For example, DIP switch 4
If it is set to 300 and the hit value is one of 150, the hit mode occurrence probability is 1/300. Instead of manually setting the probabilities with the dip switches as described above, an external terminal may be provided to remotely control a plurality of pachinko machines with one common probability setting device. In addition, a table indicating the relationship between the time, day of the day, the weather and the probability is stored in the ROM 3, and according to the elapsed time of the day by the calendar timer output, the day of the week, or the weather data manually input, the table is stored. The final value of the mode determination counter 81 may be read from the probability table. Then, automatic control of the occurrence probability of the hit mode with respect to the time and the day of the week and control for the weather can be performed. or,
In the above embodiment, the mode numerical value generating means comprises the mode decision counter 81 and step 204 in FIG. 5, and the probability control means comprises the dip switch 4 for setting the final value of the mode decision counter 81 and step 200 in FIG. , 202, 206. The outlier numerical value generating means comprises an outlier numerical value table 31, an outlier numerical value memory 82, and steps 208 to 214 in FIG. 5, and the hitting numerical value generating means comprises a hitting numerical value table 32 and a hitting numerical value memory 83. The display control means comprises a numerical display 27, a numerical display register, and steps 135 to 137 in FIG. 4, and the mode determining means mainly comprises the steps in FIG. Consists of 134. In the above embodiment, the numerical value display 27 is displayed as numerical values, but may be a design or the like. Also, when changing the display value for each of a plurality of modes such as a big hit, a middle hit, and a small hit, a plurality of display numerical tables corresponding to various hit modes are prepared, and according to the various hit modes. The display of the numerical value display 27 may be controlled based on the numerical values generated by the numerical value table. The outlier numerical value table and the hit numerical value table may be random number tables or regular tables. Further, in the above embodiment, the hit value generating means and the outlier value generating means are constituted by a numerical value table, but may be constituted by a counter or the like in which only the hitting value or the outlier value is updated. In addition, the timing for determining the numerical value for determining the hit mode may be determined at the time of winning or at the time of pressing the stop switch 20, or at another timing determined according to the winning as described above. In addition, although the numerical value of the mode determination counter 81 and the addresses of the out-of-range numerical value table 31 and the hit numerical value table 32 are synchronously changed by the same timing signal, they may be changed at different timings. Generating random numbers as described above can be applied not only to pachinko machines but also to other gaming machines such as throttle machines that cause other contingencies.

【The invention's effect】

The present invention provides mode numerical value generating means for generating a mode determining numerical value, probability control means for varying the occurrence probability of the mode determining numerical value generated by the mode numerical value generating means, and a display for controlling the display in the off mode. Outer numerical value generating means for generating a numerical value for display, and a hit numerical value generating means for generating a numerical value for display to control the display in the hit mode,
Since the mode determining numerical value and the display numerical value are generated by different means, the occurrence probability of the hit mode can be easily changed without changing the type of display or the display probability. Therefore, it is possible to control the prize ball discharge probability more finely without operating the nail of the game board.
