Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine that has improved game playability by giving a chance to the generation of data.

[0002]

2. Description of the Related Art In recent years, some pachinko machines use a computer to electronically control the winning probability of a ball. In such a pachinko machine, in order to determine the hit mode, an event that is influenced by 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. For example, a random number table is used in order to generate an event that depends on contingency. The random number table is rotated, and the random number table is rotated. There is a method in which the hit mode is determined according to the three-digit random number generated.

[0003]

In the conventional method of generating random numbers, for example, the two-digit number of the hundredth place and the first place is 250.
Random numbers are generated by rotating the street random number table.
This is a method of updating the tens digit by one every rotation and generating a three-digit random number. Therefore, 2500 random numbers are generated and the generation rate is every 1 ms, so 3
The time required for one round of the digit random number is 2.5 seconds.

On the other hand, if the stop switch is not operated, the random number for determining the winning mode is determined by the random number generated when a specific winning opening is won. However, since the winning detection of the specific winning opening is performed every 3 ms, which is a timing different from the timing of rotating the random number table, the random number that is determined at the time of winning will not be taken until 2500 random numbers have been rotated three times. sell. In other words, although the random number generation speed is 1 ms, since the random number generation timing and the winning detection timing are not synchronized, the substantial random number generation speed is reduced to 3 ms, and one cycle of random number generation is 7.5. se
becomes c.

However, the winning random number in the random number table is assigned to an appropriate position at a fixed rate so that the winning probability becomes a predetermined value. That is, the hit probability changes with a predetermined characteristic during one cycle of the random number table under the intention of the designer, and the average hit probability during one rotation of the random number table becomes a predetermined regulation value. Is set. Therefore, when the rotation cycle of the random number table becomes long, the effect of averaging the hit probability weakens, and there is a problem that the hit probability largely depends on the hit distribution of one cycle of the random number table.

Further, since random numbers that can be generated at the time of winning are skipped in the random number table, there is a problem that the characteristic of the hit probability with respect to time in one cycle differs from the intention of the designer. Further, actually, the timing of the generation of the random number table and the timing of the winning detection are not always tripled exactly as described above. Therefore, if the random numbers that can be generated at the time of winning can be evenly generated from the repeated random number table. However, there is a problem that generated random numbers are biased in a long cycle. In particular, if the timing of winning detection is 2 ms,
Only random numbers at odd or even addresses in the random number table can be generated, and the generated random numbers are biased in an infinite cycle.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. It is an object of the present invention to determine the time distribution of one cycle of the hit probability and the long term average hit probability as a predetermined value. Characteristic.

[0008]

[Means for Solving the Problems] In order to solve the above problems, the structure of the invention is to generate data in accordance with winning of a ball into a specific winning opening, and to generate a winning mode in accordance with the generated data. In the pachinko machine that determines the winning probability of the ball to the winning opening according to the mode, a timing signal output unit that outputs a timing signal, a storage unit that stores a table in which data is arranged, and a table Address updating means for updating an address in synchronization with a timing signal, winning detection means for detecting a winning of a ball of a specific winning opening in synchronization with a timing signal, and address updating means when a winning is detected by the winning detection means And a data generating means for making the data of the table related to the address updated by the data to be generated.

[0009]

Since the update timing of the address of the table and the timing of the winning detection are synchronized, the occurrence distribution of the winning mode is equal to the distribution of the data determining the winning mode in the table. Therefore, the temporal distribution of the hit probability in the short cycle (one rotation cycle) of the table is determined by the arrangement state of the data on the table, and the hit probability of the long cycle is determined by the number of hit data in the table. Both the short period probability and the long period probability are as intended by the designer of the table.

[0010]

Is connected to the oscillator circuit. The element 180 is composed of a temperature-dependent resistance element, and the cycle of the timing signal output from the timing signal generation circuit 18 changes according to the temperature change of the environment.

Reference numeral 21 denotes a power supply circuit, a signal from a start switch 23 is input to a reset signal generation circuit 19, and a reset signal, which is an output signal thereof, is supplied to the microcomputer 1

I have. Further, 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 with reference to a flowchart showing the processing procedure of the microcomputer 1. (1) Initial setting when power is turned on When the start switch 23 is turned on, power is supplied to the microcomputer 1 and a reset signal is output from the reset signal generation circuit 19 to the RST2 terminal, and the CPU 1 executes the program shown in FIG. To do. That is, the three-digit numerical registers X1, X2, and X3 displayed on the numerical display 27 are set to the initial values, and the display lamp register L storing the lighting lamps of the lamp display 29 is set to the initial values. In addition, a winning ball counter C that counts the number of winning balls that have been won and held in a specific winning hole is set to zero, and a large winning hole winning counter G that counts the number of winning balls to the special winning hole is set to zero, V The V winning ball counter A, which stores the presence / absence of winning balls in the winning opening, is initially set to zero. A state register F storing the control state
To 0 and the hit mode register R for storing the hit mode is initialized to zero, and the timers T1, T2 and T3 are initialized to zero.

Then, the data confirmation flag B which is set when the data for determining the hit mode is confirmed is reset to 0, and the address I of the table for determining the data from the table is set to 1 which is the initial value. .

(2) Background Processing Each time an external interrupt signal output from the frequency divider 15 after the initial setting is input, the CPU 1 executes the program shown in FIG. In step 100, the timer is updated. In step 102, the state signals S2, S3 of the switches 9, 11 excluding the winning detection switch 7 and the stop switch 20 are read. These status signals are configured by negative logic, and when the signal is at a low level, the switch is in the on state, indicating that a winning ball has been detected. Therefore, the falling of each state signal is detected in steps 104 and 108, and when the falling is detected, the counter G is updated and the counter A is set to 1. Step 11 below
Steps 2 to 166 are processing steps corresponding to each state.

In parallel with the processing of the main program, the winning detection, stop switch detection and data generation program shown in FIG. 5 are synchronized with a timing signal input from the RST1 terminal in a cycle shorter than the execution cycle. Is activated.
That is, in step 200, the state signal S1 of the winning detection switch 7 is input, and in the next step 202, it is determined whether or not the signal S1 has fallen. Ball Coutan C is 4
It is determined whether or not it is smaller than 4. If it is smaller than 4, the process proceeds to step 206, and the winning ball counter C is updated by 1. Then, in the next step 208, the address memory 81
The address of the table stored in
(C) Store in 83. That is, even when winning is consecutively performed, the address of the table at the time of each winning is stored in the determination memory M (C) 83. The determination in step 204 is for holding up to four winning balls.

The following steps 210 to 222 are steps for updating the address of the table. In step 210, the value of the address I is read from the address memory 81. In the next step 212, it is determined whether or not the value of the address I is the final value. If it is not the final value, the address I is updated by 1 in step 214. The value is stored in the address memory 81. If it is determined in step 212 that the value of the address I is the final value, the process proceeds to step 218, where the address I is set to the initial value of 1, and the value is stored in the address memory 81 in the next step 220. Is done.

Next, the routine proceeds to step 224, where the state signal S4 of the stop switch 20 is inputted, and the next step 22
At 6, it is determined whether or not the signal S4 has fallen.
If the signal falls, the process proceeds to step 228 and the value stored in the address memory 81 and the fixed memory M
The value stored in (1) 82 is added and the value is stored in the determination memory M (1) 82. That is, the address of the table at the time when the stop switch 20 is pressed and the address of the table at the time of the winning of the first prize ball are added. Then, in step 230, it is determined whether or not the address stored in the determined memory M (1) 82 is larger than the final value.
(1) The final value is subtracted from the address stored in 82, and the value is stored in the definite memory M (1) 82. That is, if the address exceeds the last address of the table by the adding process in step 228, the address is offset to the address in the table.

In this way, when the address of the table when the stop switch 20 is pressed within a predetermined time after winning is determined, the process proceeds to step 234 and the determination memory M
Data is read from the table corresponding to the address stored in (1), and the determined data is stored in the data memory 83. Then, the data determination flag B is set to 1 to store that the data has been determined in step 236.

If the fall of the signal output from the stop switch 20 is not detected in step 226, the process proceeds to step 238, and the timer T1 set at the time of winning in step 124 of the main program described later.
It is determined whether the time is up. If the time is not up, that is, if a certain time has not elapsed after winning,
This program ends, but if the time is up, the process proceeds to step 234, and the determined data is stored in the data memory 83 as described above. In the case of time-up, the data will be fixed at the address of the table at the time of winning.

(3) Processing when no winning ball is present When the winning ball is not present, that is, when the counter C is 0, the processing of steps 100 to 118 and 170 is performed,
Thereby, the numerical display, the lamp display, and each lamp group perform a predetermined display.

(4) When there is a winning ball (C ≠ 0) (a) Combination operation processing In step 118, the value of the counter C is determined, and when the winning is detected, the value of the counter C is decremented by 1 and the combination is performed. The register F is set to 1 to indicate the operation state, the timer T1 is set to a predetermined value, and the data confirmation flag B is reset to 0 (steps 118 to 124). Next, in step 126, it is determined whether or not the data determination flag B is set to 1, that is, whether or not the data has been determined. If it is determined that the data has not been determined, the process proceeds to step 170. . Step 1 until the data is determined
Steps 00 to 112, 126, and 170 are repeated.

On the other hand, when it is determined in step 126 that the data has been determined, the determined data is stored in the data memory 83, so the process proceeds to step 128 and the value in the data memory 83 is used to determine the winning mode. Is determined and a value corresponding to the hit mode is set in the hit mode register R. Then, since the winning mode has been determined for the first winning ball, the process proceeds to step 129, and the value of the fixed memory 82 is set to the numerical value display register X1 ,.
By setting X2 and X3, the determined data is displayed on the numerical value display 27. Then, the next step 130
Then, each value stored in the determination memory M (C) 82 is incremented by one address, and the value of the determination memory M (1) is updated so as to be the address of the table for the next re-winning ball.

The value set in the hit mode register R is 0, 1 is small, 2 is medium, and 3 is
It is a jackpot. At the time of disengagement, set register F to 0,
The process shifts to the next prize ball determination cycle.

(B) Processing at the time of hitting If the result of the determination at step 132 is a hit, the time is set to the timer T2 at step 138 according to the hit mode. Then, the above-described background processing is performed until the timer T2 determines that the time is up in step 140. 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 142 that the number of winning balls to the special winning opening is ten, the same processing as the time-up is performed even before the time-up. That is, the counter G is set to 0 in step 144.

(C) Processing when V winning ball is present When the V winning ball is present when the special winning opening is open, that is,
If the counter A is 1 (step 154), step 1
At 56, the value of the register F is set to 3 to indicate the generation of the continuation right. Then, in a step 158, the timer T3 is set to a predetermined time, and in a step 160, the time-up is determined. This process is to give a certain delay until the special winning opening is subsequently opened. Thereafter, in step 162, the register R is set to the value 3 indicating the big hit, and the process proceeds to step 136 to perform the above-mentioned hit processing. However, the continuation right is adjusted in step 146 so that it does not occur more than 10 times.

Although the numerical display 27 of the above embodiment displays the generated data itself, it may display a combination of symbols or the like corresponding to the data. Further, it may be constituted by a rotating drum or the like. In the above embodiment, the pachinko machine has been described. However, the present invention can be applied to a gaming machine such as a throttle machine that causes other accidents. In the case of a throttle machine, the start timing of the device is the winning detection timing of the pachinko machine.

[0033]

As described above, according to the present invention, the table update timing and the winning detection timing, which is the data confirmation timing for determining the winning mode, are synchronized, so that the time distribution of one cycle of the winning probability and the long-term average. The hit probability can be accurately controlled by the data arrangement on the table as designed and the ratio of the number of hit data to the total data. Therefore, it is possible to eliminate the phenomenon that the winning probability is unexpectedly biased in time.
