DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine that prevents a player from intentionally determining a winning mode.

[0002]

2. Description of the Related Art 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. Random numbers are used to generate events that depend on chance. After winning the sphere to particular winning hole, rotate the display of the numeric indicator, determined per mode in response to the stop display random number with stop showing the subsequent stop switch pressing or the like <br/> doing.

[0003]

However, when a player wins a specific winning opening, a lamp or a sound is generated, and the player presses a stop switch depending on the lighting of the specific lamp or the specific sound, and the stopped random number is displayed. There is an adverse effect such that the timing for specifying is always controlled to be constant. As described above, after the ball is won in the specific winning opening and the three-digit display is driven, the timing at which the display is stopped by the player may be controlled at the same timing based on the empirical intuition of the player. There was a problem that the jackpot was fired repeatedly.

[0004] Accordingly, it is an object of the present invention to enable a mode to be determined by more contingency without intervening a player's intention in determining a winning mode.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a method for hitting a ball in a specific winning opening.
Ri mode determines, in pachinko machines for controlling the prize probability of the sphere to the winning openings in accordance with the mode, memory means for storing a table, always regardless of address tables prize for a particular winning hole, timing and updating means for updating in synchronization with the signal, based on the values stored in the table of addresses when winning the determined specified winning opening by updating means
And a display for displaying a random number after a predetermined time has elapsed after the winning or when the stop switch is operated.

[0006]

The address of the table for stopping and displaying the random numbers is constantly updated by the address updating means in synchronization with the timing signal regardless of the winning. Then, the value stored in the address table at the time of winning the specific winning opening is stopped and displayed as a random number at the time of winning. Then, the winning mode setting means determines the winning mode based on the stopped and displayed random number. Thus, instead of a random number using a stop switch as in conventional pachinko machines are stopped and displayed, a random number to be displayed is stopped, because it is determined by the timing at the time of winning a table which is rotating at all times, the player Prevents the adverse effect that the random number to be stopped and displayed is intentionally determined. In addition, the display on the display is stopped after a predetermined time has elapsed after winning or when the stop switch is operated, and the hit mode is presented to the player as a still display. Therefore, it is possible to give the player an impression as if the winning mode is determined by the chance of the change state of the display on the display.

FIG. 1 is a block diagram showing an electrical configuration of the apparatus according to the present embodiment. The microcomputer 1 is used for the control device. An external ROM 3 and an external RAM 8 are connected to the microcomputer 1. A random number table 31 shown in FIG. 6 is formed in the ROM 3, and a random number memory 81 that stores a random number that changes every moment and a determination memory 82 that stores a determined random number that determines a hit mode are stored in the RAM 8. Is formed. The determined memory 82 has a memory of the number of reserved prize balls of the specific winning opening + 1, and a random number for each reserved prize ball has already been determined at the time of prize winning. Determination memory 82
Is stored.

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 detecting switch 11 for detecting a winning ball in a V winning opening, and a stop. Switch 20
Are 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 of FIG. 4 in synchronization with the external interrupt signal.

A timing signal output from the timing signal generation circuit 18 is input to the RST1 terminal of the microcomputer 1, and a random number generation program shown in FIG. 5 is started in synchronization with the timing signal. An element 180 for determining the cycle of the output timing signal is connected to the oscillation circuit. The element 180 is formed of a temperature-dependent resistance element, and the cycle of the timing signal output from the timing signal generation circuit 18 changes according to a change in environmental temperature.

Reference numeral 21 denotes a power supply circuit, and a signal from a start switch 23 is input to a reset signal generation circuit 19,
The reset signal, 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 numerical value display 27, the lamp display 29, and the stored number display 30 are connected to the display drive circuit 25 and the display selection circuit 28. These displays are dynamically driven by outputting selected data and display data from the microcomputer 1 at regular intervals. That is, the display selecting circuit 28
Each display unit is selected and displayed according to the output signal of the display drive circuit 25 at that time. The driver 39 responds to a signal from the microcomputer 1 by a solenoid 41
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 the above configuration will be described with reference to 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, power is supplied to the microcomputer 1 and the reset signal generating circuit 19
Outputs the reset signal S4 to the RST2 terminal. Then
The CPU 1 executes the processing shown in FIG. That is, a three-digit numerical register X1, X2, X displayed on the numerical display 27.
3 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 hit mode register R storing the hit mode is initialized to zero, and the timers T1, T2, T3 are initialized to zero. The tenth digit of the random number stored in the random number memory 81 is the initial value of 1
, And the address I of the random number table for determining the hundredth digit and the first digit of the random number from the random number table is set to the initial value of 1.

(2) Rotation of Random Number Table In parallel with the processing of the main program of FIG. 4, the random number generation program shown in FIG. 5 is started in synchronization with the timing signal input from the RST1 terminal. That is, in step 200, the numerical value stored at the address I is read from the random number table 31 and the numerical value is stored in the hundreds digit and the first digit of the random number memory 81. Then, in the next step 202, it is determined whether or not the value of the address I is the final value. If the value is not the final value, the address I is updated by 1 in step 204, and the random number generation program ends. Step 20
If the value of the address I is determined to be the final value in step 2, the process proceeds to step 206, where the address I is set to the initial value of 1. In step 208, the tens digit of the random number is set to 1
Only be advanced.

As described above, random numbers are generated in the random number memory 81 at an arbitrary time after the pachinko machine is reset. Since the generation speed of the random numbers at this time is determined by the timing signal output from the timing signal generation circuit 18, the generation speed of the random numbers also changes according to the environmental conditions (temperature).

(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, a timer updating process is performed, and in step 102, the state signals S1, S2, and S3 of the switch group are 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, steps 104, 110, 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 counted up to only 4 in step 106.

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 set to 1 in step 108. Is updated, and the value of the random number memory 81 at that time is determined in step 109.
Stored in M (C) 82. 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 random number memory 81 at that time is determined memory
Stored in M (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 random number memory 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, each random number is determined.

The next steps 118 to 166 are as follows:
This is a processing step corresponding 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.
Thereby, the numerical value display, the lamp display, and each lamp group perform 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 one, and a register F is set to 1 to indicate the combination operation state. T1 is set to a predetermined value (steps 124 to 130). And
As the winning ball counter C is decremented in step 132, the contents of the determined memory M (C) are incremented and updated one by one.

Next, at step 133, it is determined whether or not the time of the timer T1 has expired.
Is determined, and if the stop switch 20 is pressed, the hit mode is determined from the value of the determination memory M (0), and the hit mode is set in the hit mode register R. The value of the determined memory M (0) is displayed on the numerical value display 27. Also, when it is determined in step 133 that the time is up, the above-described processing of step 136 is executed.

Therefore, the stop switch 20 and the time-up command the stop of the rotation display of the numerical value display 27, only the determination of the hit mode and the start of the next processing according to the mode. It has already been determined at the time of winning. Steps 100 to 118, 133, and 13 are performed until the stop switch 20 is pressed or the time is up.
The processing of 4,170 is repeated. Hit mode register R
Are 0, 1 is a small hit, 2 is a medium hit, and 3 is a big hit. If it is 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 winning If the result of the determination at step 139 is a winning, a time is set to the timer T2 at step 144 according to the winning mode. Then, the above-described processing is performed until the timer T2 determines in step 146 that the time is up. 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, at 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 large winning opening is open, ie,
If the counter A is 1 (step 156), step 1
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. Thereafter, in step 166, the register R is set to the value 3 indicating the big hit, and the process proceeds to step 142 to perform the above-mentioned hit processing. However, the continuation right is adjusted in step 152 so as not to occur more than ten times.

In the above embodiment, the random number generation speed is varied according to the environmental temperature. However, the random number generation speed may be varied according to the environmental sound pressure, humidity, vibration and the like.
Generating random numbers as described above can be used not only in pachinko machines but also in other gaming machines such as throttle machines that cause other contingencies.

[0028]

According to the present invention, the table is always rotated, and when a specific winning opening is won, the value determined by the table at that time is displayed in a stop mode for determining the winning mode.
Since the random numbers are stopped , the random numbers stopped and displayed are completely controlled by chance, and are not controlled by the intention of the player.
