The generating speed of random numbers is determined by the timing signal of output generated from a timing signal generating circuit 18.

Description

[Detailed description of the invention] [Industrial application field]

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

[Prior art]

In recent years, pachinko machines use computers to electronically control the winning probability of balls. In such pachinko machines, in order to determine the winning mode,
An event that depends on chance occurs, a winning mode is determined from that event, and the development of a more complex game is controlled in response to the winning mode. and,
For example, a random number table is used to generate events that depend on chance. This random number table is rotated after winning a prize, and the display on the numerical display is also rotated, and the value of the random number table when the stop switch is subsequently pressed is the random number to be generated. Then, this random number is displayed on the numerical display, and the winning mode is determined according to the random number.

[Problems to be solved by the invention]

However, when a player enters a specific winning slot, a lamp and sound are generated, and the player presses the stop switch relying on the lighting of the specific lamp and the specific sound, so that the timing to identify the random numbers generated is always the same. There were negative effects such as being controlled by the government. In this way, after a ball enters a specific winning opening and the 3-digit display is driven, there is a risk that the timing at which the display is stopped by the player may be controlled to the same timing by the player's empirical intuition. However, there was a problem in that the jackpots were repeatedly hit.

[Means to solve the problem]

The present invention provides: a storage means for storing a random number table; an updating means for always updating the address of the random number table in synchronization with a timing signal regardless of whether a prize is won in a specific winning slot; and a specific information determined by the updating means. Random number generating means that uses a numerical value stored in a random number table of the address at the time of winning the winning opening as the random number at the time of winning, and a winning mode that determines a winning mode based on the random number at the time of winning generated by the random number generating means. It consists of a decision means.

[Effect]

The address of the random number table that specifies the random number is constantly updated in synchronization with the timing signal by the address updating means, regardless of winnings. Then, by means of random number generation,
The random number stored in the random number table of the address at the time of winning in the specific winning opening is determined as the random number at the time of winning. Then, the winning mode is determined by the winning mode setting means based on the determined random number at the time of winning. Therefore, the random numbers are not determined using a stop switch like in conventional pachinko machines, but the random numbers are determined by the constantly rotating random number table and the timing of winning a prize, so the random numbers are determined by the player. The harmful effects of intentional decisions are prevented.

【Example】

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 holes, among which 52, 53, 54.

The numerical display 27 is a three-digit LED display, and the lamp display 29 is a lamp in which red and blue LEDs are arranged cyclically. When you enter a specific winning slot, 3 will be displayed on the numerical display 27 to determine the winning mode.
The numerical value of the digits changes. Then, when the player presses the stop switch 20 within a predetermined time after winning a prize, or when a predetermined time elapses, the fluctuating numerical value stops. Furthermore, this numerical display 2
The fluctuating numerical value of 7 is unrelated to the rotation of the random number table, and when the rotation of the numerical display 27 stops, the random number that has already been determined at the time of winning is displayed on the numerical display, regardless of the fluctuating numerical value at that time. It is now displayed on 27. Then, the winning mode is determined from the value at that time, and the opening time etc. of the opening/closing door 64 of the big prize opening 63 are controlled according to that mode. Furthermore, the game board 51 is provided with various indicators and lamps for displaying operating states. 30 in the center is
This is a memorized number display for displaying the number of pending winning balls that have entered a specific winning hole and are pending winning processing. 47
A to 47j are operating lamps that blink during a combination operation to determine the winning remote. 43a to 43c are panic lamps that flash together with lamps 47a to 47j when a jackpot is won. Further, 45a to 45c are V lamps that flash when there is a prize in the (1) winning prize slot 63. FIG. 1 is a block diagram showing the electrical configuration of the device of this embodiment. A microcomputer 1 is used as a control device. An external ROM 3 and an external RAM 8 are connected to the microcomputer l. A random number table 31 shown in FIG. 6 is formed in the ROM 3, and a random number memory 81 in which random numbers that change from time to time are stored, and a determination memory 82 in which determined random numbers for determining the winning mode are stored. is formed. The confirmation memory 82 has a memory equal to the number of pending winning balls in the specific winning opening + 1, and the random number for each pending winning ball has already been determined at the time of winning, and the random number determined at the time of winning is used for each pending winning ball. is stored in the confirmation memory 82 of. A winning detection switch 7 that detects a winning ball in a specific winning opening, a winning opening detection switch 9 that detects a winning ball in a special winning opening, and a V winning detection switch 11 that detects a winning ball in a winning opening. The stop switch 20 is connected to the microcomputer 1 via a waveform shaping circuit 13 consisting of a flip-flop to prevent 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. Further, a timing signal output from the timing signal generation circuit 18 is input to the R3Tl terminal of the microcomputer 1, and a random number generation program shown in FIG. 5 is activated in synchronization with the timing signal. An element 180 that determines the period of the timing signal to be outputted is connected to the oscillation circuit of the timing signal generation circuit 18. 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 changes in the temperature of the environment. Further, 21 is a power supply circuit, the signal of the start switch 23 is input to the reset signal generation circuit 19, and the output signal of the reset signal is R3 of the microcomputer 1.
The reset signal is input to the T2 terminal, and the initial program shown in FIG. 3 is activated by the reset signal. A display drive circuit 25, a display selection circuit 28, and a driver 39 are connected to each output port of the microcomputer 1. Display drive circuit 25, display selection circuit 28
The above-mentioned numerical value display 27, lamp display 29, and memory number display 30 are connected to. These displays are dynamically driven by outputting selection 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 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, and controls the lighting operations of the panic lamp 43, the ■ lamp 45, and the operation lamp 47. Next, the operation of the pachinko machine having such a configuration will be explained based on a flowchart showing the processing procedure of the microcomputer 1. (1) When the initial set start switch 23 is turned on when the power is turned on, power is supplied to the fibrocomputer 1, and the reset signal generation circuit 19 outputs the reset signal s4 to the RST2 terminal. Then, the CPUI executes the process shown in FIG. That is, the three-digit numerical registers Xi and X2 displayed on the numerical display 27
．． X3 is set to the initial value, and the display lamp register L, which stores the lighting lamp of the lamp indicator 29, is set to the initial value. In addition, the winning ball counter C, which counts the number of pending winning balls that have entered a specific winning hole and is on hold, is set to zero, and the winning ball counter G, which counts the number of winning balls that have entered the grand winning hole, is set to zero.
2. Initialize the V winning ball counter A, which stores the presence or absence of a pending winning ball in the winning hole, to zero. In addition, the state register F that stores the control state is initialized to zero, the winning mode register R that stores the winning mode is initialized to zero, and the timer T is set to zero.
I. T2. T3 is 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 for determining the hundreds digit and the ones digit of the random number from the random number table is set to the initial value. Set to a value of 1. (2) Rotating the random number table Following the main program processing in Figure 4, R3T
A random number generation program shown in FIG. 5 is activated in synchronization with a timing signal input from one terminal. That is, in step 200, the numerical value stored at 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, 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 ■ is updated by 1 in step 204, and the present random number generation program is terminated. Furthermore, if the value of the address ■ is determined to be the final value in step 202, the process moves to step 206, where the address ■ is set to the initial value 1, and in the next step 208, the tens digit of the random number is The number is incremented by 1. In this way, random numbers are generated in the random number memory 81 at any time after the pachinko machine is reset. Since the random number generation rate at this time is determined by the timing signal output from the timing signal generation circuit 18, the random number generation rate also changes depending on the environmental conditions (temperature). (3) Main program After initial setting, the CPUI executes the main program shown in FIG. 4 every time an external interrupt signal output from the frequency divider 15 is input. In step 100, a timer update process is performed, and in step 102, the status signals St, 32, 33 of the switch group are read. These status signals are composed of negative logic, and when the signals are at a low level, the switch is on, indicating that a winning ball has been detected. Therefore, step 104.110.114
The falling 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 pending winning balls is
So, I try to only count up to 4. When a winning in a specific winning hole is detected, the determination in step 104 becomes YIES, and if the number of reserved winning balls is smaller than 4 in step 106, step 10
At step 8, the winning ball counter C is updated by 1, and at step 10
9, the value of the random number memory 81 at that time is confirmed memo IJM(
C) Stored in 82. That is, when a winning in a specific winning hole is detected in a state where there is no pending winning ball, the winning ball counter C becomes l, and the value of the random number memory 81 at that time is stored in the fixed memory M(1). Further, when the winning ball counter C is 1 or more, if a winning ball is further entered into a specific winning hole, that winning ball becomes a reserved winning ball, and the winning ball counter C is incremented by 1. Then, the value of the random number memory 81 at the time of winning is stored in the confirmation memory M(C) corresponding to the reserved winning ball. In this way, each random number is determined when a specific winning hole is won. The next steps 118 to 166 are processing steps 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 124.170 is performed, and the numerical display and lamp display container, each lamp group,
Perform a predetermined display. (b) The value of counter C is determined in combination operation processing step 124, and when a winning is detected, the value of counter C is subtracted by 1, register F is set to 1 to indicate the combination operation state, and timer T1 is set to a predetermined value. (steps 124-130). and,
As the winning ball counter C is decremented in step 132, the contents of the confirmed memo IJM(C) are incremented by one and updated. Next, in step 133, it is determined whether or not the timer T1 has timed up. If it is determined that the timer has not timed up, it is determined in step 134 whether or not the stop switch 20 has been pressed. If the stop switch 20 has been pressed, The winning mode is determined from the value of the definite memory M(0), and the winning mode is set in the winning mode register R. Also, the value of the confirmed memo UM (0) is displayed on the numerical display 27.
will be displayed. Also, when it is determined in step 133 that the time has expired, the above processing in step 136 is executed. Therefore, the stop switch 20 and time-up only command the rotation display of the numerical display 270 to stop, determine the winning mode, and command the start of the next process according to that mode, and the random number has already been determined at the time of winning. ing. Further, until the stop switch 20 is pressed or the time-out occurs, steps 100 to 118, 133, 134.
Repeat the process of step 170. The value set in the winning mode register R is 0,
1 is a bad win, 2 is a medium hit, and 3 is a big win. If it is a miss, the register F is set to O and the cycle moves to the next winning ball determination cycle. (C) Winning process When the determination result in step 139 is a win, a time is set in the timer T2 in step 144 according to the winning mode. The above-described processing is then performed until timer T2 is determined to have timed up in step 146. As a result, the grand prize opening will remain open for a predetermined period of time.
A group of lights serves as an indication of a panic state. At this time,
When it is determined in step 148 that the number of winning balls into the big winning hole is 10, the same process as the time up is performed even before the time up. That is, in step 150, the counter G is set to O.
Set register R to 0. (d) Processing when a V-winning ball is present If a V-winning ball exists when the grand prize opening is open, that is,
When counter A is 1 (step 156), step 1
In step 58, the value of register F is set to 3 to indicate the occurrence of the continuation right. Then, in step 162, the timer T3 is set to a predetermined time, and in step 164, time-up is determined. This process is to provide a certain delay until the big prize opening is subsequently opened. Thereafter, in step 166, the register R is set to the value 3 indicating a jackpot, and the process proceeds to step 142, where the above-mentioned winning process is performed. However, the continuation right is adjusted in step 152 so that it does not occur more than 10 times. In the above embodiment, the rate of random number generation is varied depending on the environmental temperature, but it may also be varied depending on the sound pressure, humidity, vibration, etc. of the environment. Furthermore, generating random numbers as described above can be used not only for pachinko machines but also for other gaming machines that generate chance, such as throttle machines.

【Effect of the invention】

In the present invention, the random number table is constantly rotated, and when a prize is won in a specific winning slot, the random number determined by the random number table at that time is used as the random number for determining the winning mode, so the generated random number is completely coincidental. It is not controlled by the player's intentions.
