DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

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

[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. Then, for example, a random number table is used to cause an event that depends on the 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, the 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 prize is won in a specific winning opening, a lamp or sound is generated, and the player presses the stop switch depending on the lighting of the specific lamp or the specific sound, so that the timing for specifying the generated random number is always constant. There was an adverse effect such as being controlled by. 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.

[Means for solving the problems]

The present invention, a storage means for storing a random number table, an updating means for constantly updating the address of the random number table in synchronization with a timing signal regardless of whether a winning is made to a specific winning opening, and a ball winning to the specific winning opening Detecting means for detecting, a random number generating means for making the numerical value stored in the random number table of the address by the updating means when the winning is detected at the specific winning opening of the ball the random number at the time of winning, and a random number generating means The winning mode determining means determines the winning mode based on the random number at the time of winning generated by.

[Action]

The address of the random number table for specifying the random number is constantly updated by the address updating means in synchronization with the timing signal regardless of winning. When the detecting means detects the winning of the ball to the specific winning opening, the random number generating means determines the random number stored in the random number table of the address at the time of winning the specific winning opening as the winning random number. . Then, the winning mode setting means determines the winning mode based on the determined random number at the time of winning. Therefore, instead of using a stop switch to determine the random number as in a conventional pachinko machine, the random number is determined by the constantly rotating random number table and the timing of winning, so the random number is determined by the player. The harmful effects of intentional decision are prevented.

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 in which random numbers that change from moment to moment are stored in the RAM 8 and a fixed memory 82 in which fixed random numbers for determining the winning mode are stored. Are formed. Its confirmed memory
82 has a memory of only the number of pending prize balls of a specific winning opening + 1, the random number for each pending prize ball is already determined at the time of winning, and the random number determined at the time of winning is the fixed memory of each pending prize ball. It is stored in 82. A prize detection switch 7 for detecting a prize ball at a specific prize hole, a prize hole detection switch 9 for detecting a prize ball at the special prize hole, and a V for detecting a prize ball at the V prize hole
The winning detection switch 11 and the stop switch 20 are connected to the microcomputer 1 via a waveform shaping circuit 13 including 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 the random number generation program shown in FIG. 5 is started in synchronization with the timing signal. An element 180 that determines the cycle of the timing signal output to the timing signal generation circuit 18 is connected to the oscillation circuit. The element 180 is composed of a resistance element having temperature dependency, and the cycle of the timing signal output from the timing signal generation circuit 18 changes according to the temperature change of the environment. Further, reference numeral 21 is a power supply circuit, the signal of the start switch 23 is input to the reset signal generation circuit 19, and the reset signal which is the output signal thereof is input to the RST2 terminal of the microcomputer 1. , The initial program shown in FIG. 3 is started. 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 display devices are dynamically driven by outputting the selection data and the 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. In addition, the winning prize ball counter C that counts the pending winning prize balls that have been won and held in the specific winning prize hole is set to zero, and the large winning prize prize winning counter G that counts the number of winning prize balls to the special winning prize prize is set to 0, and the V winning prize is given. A V winning ball counter A, which stores the presence or absence of a reserved winning ball in the mouth, is initially set to zero. Further, 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. 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 initialized. It is set to the value 1. (2) Rotation of the 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, step 20
At 0, the numerical value stored in the address I is read from the random number table 31, and the numerical value is stored in the 100th digit and the 1st 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, and if it is not the final value, the address I is updated by 1 in step 204 and the random number generation program is terminated. If the value of address I is determined to be the final value in step 202,
In step 206, the address I is set to the initial value 1, and in the next step 208, the numerical value of the tens digit of the random number is incremented by 1. In this way, a random number is generated in the random number memory 81 at an arbitrary time after the pachinko machine is reset. The random number generation speed at this time is determined by the timing signal generation circuit.
Since it is determined by the timing signal output from 18, the random number generation rate also changes according to environmental conditions (temperature). (3) Main program After the initial setting, the CPU 1 executes the main program of FIG. 5 every time the 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 random number memory 81 at that time is stored in the determination memory M (C). That is, when the winning in the specific winning opening is detected without the reserved winning ball, the winning ball counter C becomes 1, and the value of the random number memory 81 at that time is stored in the determination memory M (1). Further, when the prize winning ball counter C is 1 or more, if the player further wins a prize at the specific winning opening, the prize winning ball becomes a reserved prize winning ball,
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 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 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, and 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. Set to the value (steps 124 to 130). And step
As the winning ball counter C is decremented in 132, the contents of the finalized memory M (C) are incremented by one and updated. Next, in step 133, 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 134 whether or not the stop switch 20 has been pressed, and the stop switch 20 is pressed. In this case, 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. or,
The value of the fixed memory M (0) is displayed on the numerical 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 are indicated by the numerical display.
Only the command to stop the rotation display of 27, the determination of the winning mode and the start time of the next process according to the mode are given, and the random number has already been determined at the time of winning. Further, the processing of steps 100 to 118, 133, 134, 170 is repeated until the stop switch 20 is pressed or the time is up. The values set in the hit mode register R are 0, 1 is a small hit, 2 is a middle hit, and 3 is a big hit. When the player is out of position, the register F is set to 0, and the process goes to the next winning ball determination cycle. (C) Processing when hitting When the judgment result in step 139 is hitting, the time is set in the timer T2 in step 144 according to the hitting 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, step
When it is judged that the number of winning balls to the big winning opening is 10 in 148,
Even before the time is up, the same processing as the time up is performed. That is, in step 150, the counter G is set to 0 and the register R is set.
Set to. (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, the register R is set to a value of 3 which indicates a big hit, and the process proceeds to step 142 to perform the above-mentioned hitting process. However, the continuation right must be stepped so that it does not
Adjusted at 152. In the above embodiment, the random number generation speed is changed according to the environmental temperature, but it may be changed according to the environmental sound pressure, humidity, vibration and the like.

【The invention's effect】

The present invention constantly updates the address of the random number table for determining the random number, detects the winning of the ball to the specific winning opening, using the address when the winning of the ball to the specific winning opening is detected, Since a random number is determined from the random number table and the random number is used as a random number for determining the mode, the generated random number is completely controlled by an even number and is not controlled by the player's intention.
