DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine in which game playability is further improved by making data generation coincidental.

[0002]

2. Description of the Related Art Some recent pachinko machines use a computer to electronically control the winning probability of a ball. 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 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.
The random number table is rotated to generate random numbers.
This is a method of updating the tens digit by one every rotation and generating a three-digit random number. Accordingly, 2500 random numbers are generated, and the generation speed is every 1 ms.
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 at a timing different from the timing of rotating the random number table, the random numbers determined at the time of winning are all the random numbers after the 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. For this reason, when the rotation cycle of the random number table becomes longer, the effect of averaging the hit probability is weakened, and the hit probability is greatly affected by the hit distribution in 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 To solve the above-mentioned problems, the configuration of the present invention is to determine whether or not to increase the prize ball launch rate.
In the pachinko machine to control the winning probability of the sphere to the winning openings in accordance with the per mode indicating either determine the interrupt signal output means for outputting an interrupt signal, the hit mode in synchronization with the interrupt signal
A data updating means for updating the data for the constant, detection means for detecting monitoring the passage of a specific position of the sphere in synchronization with the interrupt signal, the data of the data updating means when a specific position ball has passed Data generating means for generating data for determining the hit mode.

[0009]

Since the timing for updating the data for determining the hit mode and the timing for detecting that the ball passes the specific position are synchronized by the interrupt signal , the occurrence distribution of the hit mode is determined by the data for determining the hit mode. Is equal to the occurrence distribution of Therefore, the temporal distribution of the hit probability in the short cycle (one rotation cycle) of the data occurrence distribution is determined by the data occurrence distribution, and the long cycle hit probability is determined by the hit data in the one-cycle data distribution that occurs. , The short-term probability and the long-period probability both occur as intended by the person who designed the data distribution.

I have. 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 at power-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 generating circuit 19 to the RST2 terminal, and the CPU 1 executes the program shown in FIG. I 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. Further, the winning ball counter C for counting the number of winning balls that have been won and held in the specific winning opening is set to zero, the special winning opening winning counter G for counting the number of winning balls to the special winning opening is set to zero, and V A V winning ball counter A that stores the presence or absence of a winning ball in the winning port is initialized to zero. A state register F storing the control state
Is set to zero, 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, when the data for determining the hit mode is determined, the data determination flag B which is set is reset to 0, and the address I of the table for determining the data from the table is set to the initial value of 1. .

(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 the value is smaller than 4. If the value is smaller than 4, the process proceeds to step 206, and the winning ball counter C is updated by one. Then, in the next step 208, the address memory 81
The address of the table stored in the memory M
(C) Store it 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. Note that the determination in step 204 is to limit the number of winning balls to be held to four.

The next 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, and in the next step 212, it is determined whether or not the value of the address I is the final value. If not, 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, where 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 is determined by the address of the table at the time of winning.

(3) 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 118 and 170 is performed.
Thereby, the numerical value display, the lamp display, and each lamp group perform 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. When a winning is detected, the value of the counter C is decremented by one, and The register F is set to 1 to indicate the operation state, the timer T1 is set to a predetermined value, and the data determination 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, if it is determined in step 126 that the data has been determined, since the determined data has been stored in the data memory 83, the flow proceeds to step 128 to determine the hit mode from the value in the data memory 83. Is determined, and a value corresponding to the hit mode is set in the hit mode register R. Then, since the winning mode is determined for the first winning ball, the process proceeds to step 129, and the value of the determination memory 82 is stored in 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. When it is off, set the register F to 0,
The process proceeds to the next winning 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 to indicate 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 a V Win Ball Exists If the V win ball exists when the large winning opening is open, ie,
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 for giving 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 ten 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]

According to the present invention, the data update timing is synchronized with the detection timing for detecting that the ball has passed a specific position, which is the timing for determining the data for determining the hit mode, by an interrupt signal . Therefore, the time distribution of one cycle of the hit probability and the long term average probability of hit can be accurately controlled by the occurrence distribution of the designed data and the ratio of the number of the hit data to all the data. Therefore, it is possible to eliminate the phenomenon that the winning probability is unexpectedly biased in time.
