Then, the display of the variable indicator is determined and stopped according to the hit or miss mode determined when the ball at the specific position passes, and the winning probability of the winning opening which is opened and closed according to the hit mode is determined. Control. Hereinafter, the present invention will be described with reference to specific examples. FIG. 2 is an external view showing the mechanism of the pachinko machine. The game board 51 has various winning openings,
Of these, 52, 53, and 54 are specific winning openings, and when the specific winning opening is won, a combination operation for determining a winning mode is started. 56, 57, 58, 59, 60
Ordinary winning ports, and 61 and 62 are winning ports with a tulip-type accessory. Reference numeral 63 denotes a large winning opening (variable winning opening) which is opened and closed according to the winning mode, and the opening and closing door 64 is opened and closed by a solenoid 41 provided therein. Further, a V winning opening 65 is provided at the center of the special winning opening 63, and when the V winning opening 65 is won, the opening / closing door 64 generates a continuation right to open and close continuously. ing. [0007] In the center of the play board 51, a specific winning opening 5

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 cyclically arranged. When a specific winning opening is won, the three-digit numerical value displayed on the numerical value display (variation display) 27 changes in order to determine the winning mode. Then, when the player presses the stop switch 20 within a predetermined time after winning, or when the predetermined time elapses, the fluctuated numerical value is stopped, and the winning mode is determined from the value at that time, and according to the mode, the big winning opening The opening time of the opening / closing door 64 of 63 is controlled. [0008] The game board 51 is provided with various indicators and lamps for displaying the operation state. Reference numeral 30 in the center is a stored number display for displaying the number of balls that have won a specific winning opening and have been suspended.
47a to 47j are operation lamps that blink during the combination operation for determining the winning mode. 43a-43
c is a panic lamp that blinks with the lamps 47a to 47j at the time of a big hit. 45a-45c is V
This is a V lamp that flashes when there is a winning in the winning opening 65. FIG. 1 is a block diagram showing an electrical configuration of the apparatus of this 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. Then, the random number table 3 shown in FIG.
1 is formed, and a random number memory 81 for storing a random number that changes every moment and a fixed memory 82 for storing a fixed random number that determines a hit mode are formed in the RAM 8. A winning detection switch 7 for detecting a winning ball in the special winning opening 52, 53, 54, a special winning opening winning detection switch 9 for detecting a winning ball in the special winning opening 63, and a winning ball in the V winning opening 65 are detected. The V winning detection switch 11 and the 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. RST1 of the microcomputer 1
A timing signal output from the timing signal generation circuit 18 is input to the terminal, 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. The signal of the start switch 23 is input to the reset signal generation circuit 19, and the output reset signal 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 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, each display unit is selected by the display selecting circuit 28, and the display driving circuit 2 at that time is selected.
5 is displayed in accordance with the output signal of No. 5. The driver 39 drives the solenoid 41 according to a signal from the microcomputer 1 and controls the blinking 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) When the initial set start switch 23 at the time of power-on is turned on, power is supplied to the microcomputer 1 and the reset signal generation circuit 19
Outputs the reset signal S4 to the RST2 terminal. Then, the CPU 1 executes the processing shown in FIG. That is,
3-digit numerical registers X1, X displayed on the numerical display 27
2, X3 are set to the initial values, and the display lamp register L storing the blinking lamps of the lamp display 29 is set to the initial values. Also, a winning prize ball counter C for counting the number of prize balls that have been won and held in the specific prize port is set to zero, and a special prize port winning counter G for counting the number of prize balls to the special winning port is set to zero. A V winning ball counter A that stores the presence or absence of a winning ball in the winning port is initialized to zero. Further, the state register F storing the control state is initialized to zero, and the hit mode register R storing the hit mode is initialized to zero.
1, T2 and T3 are initialized to zero. Then, the tenth digit of the random number stored in the random number memory 81 is set to 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 initialized. The value 1
Is set to (2) After the initial setting of the background processing, the CPU 1 executes the program shown in 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 signal S
1, S2 and S3 are read. These status signals are
The switch is in the ON state when the signal is at a low level, indicating that a winning ball has been 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 counted up to only 4 in step 106. Step 118 to step 166
Are processing steps corresponding to each state. In parallel with the processing of the main program, a random number generation program shown in FIG. 5 is started in synchronization with a 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. And
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. If it is determined in step 202 that the value of the address I is the final value, the process proceeds to step 206, where the address I is set to the initial value of 1, and the next step 208
Updates the tens digit of the random number by one. 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. (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 124 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) The value of the counter C is determined in the combination operation processing step 124, and when a winning is detected, the value of the counter C is decremented by one to change the combination operation state. To indicate this, the register F is set to 1 and the timer T1 is set to a predetermined value (steps 124 to 130). And
In step 132, the random number determining process, that is, the value of the random number memory 81 when the specific winning opening is won is set in the determination memory 82, so that the random number for determining the winning mode is determined. 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 has been pressed. In step 135, the value of the random number memory 81 is set in the determination memory 82 in step 135, and
The random number that determines the hit mode set in is corrected. As described above, the random number at the time of winning a specific winning opening or the random number generated at the time when the stop switch 20 is pressed within a predetermined time after the winning is used as a basis for determining the hit mode, so that the determination memory 82 Is stored. Therefore, in the former case, the mode in which the value of the random number obtained at the time of winning the specific winning opening, that is, when detecting that the ball has passed the specific position, is determined to be a hit or a miss. Then, the process proceeds to step 136, where the determined random number is displayed on the numerical value display 27 by setting the value of the determined memory 82 in the numerical value display registers X1, X2, X3. Then, in the next step 137, the hit mode is determined according to the determined random number. As described above, the three-digit numerical value displayed on the numerical value display (fluctuation display) 27 fluctuates from the time of winning the specific winning opening,
When the predetermined time elapses, the changed numerical value stops, and such display is controlled in step 170. At this time, the determined random number is determined by a random number that changes in synchronization with a timing signal whose period fluctuates according to the temperature of the environment. Therefore, even if the stop switch 20 is pressed with a certain regularity, the random number is not changed. Since the fluctuation speed changes depending on the temperature of the environment, it is impossible to intentionally set the determined random number to a specific value. Until the stop switch 20 is pressed or the time is up, the processing of steps 100 to 118, 133, 134, and 170 is repeated. The values set in the hit mode register R are 0 out, 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. (B) Winning Process When the result of the determination in step 139 is a hit, a time is set in the timer T2 in step 144 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 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. That is, the opening time of the opening / closing door 64 at the special winning opening 63 is controlled in accordance with the determined winning mode, which corresponds to controlling the winning probability of a ball to the variable winning opening. At this time, if it is determined in step 148 that the number of penetrating balls into the special winning opening is 10, the same processing as the time-up is performed even before the time-up. That is, in step 150, the counter G is set to 0 and the register R is set to 0. (C) Processing when a V Win Ball Exists The V win ball exists when the large winning opening is open, that is,
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 processing is for giving a certain delay until the special winning opening is subsequently opened. After this,
In step 166, the register R is set to the value 3 indicating the big hit, and the process shifts 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 depending on the environmental temperature. However, the random number generation speed may be varied depending on 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. When a specific winning opening is won during operation, the value of the random number at that time may be stored as the determined random number. If the value of the random number is stored in this way, the mode of whether the value of the random number obtained at the time of winning the specific winning opening, that is, when detecting that the ball has passed the specific position, always hits or misses. Will be determined. Further, when the stop switch 20 is pressed, the random number of the address according to the sum of the address of the random number table at the time of winning the specific entrance and the address of the random number table when the stop switch 20 is pressed is determined. It may be a random number. According to the present invention, a certain value is generated by a program started at an arbitrary time after the pachinko machine is reset, and the same value obtained when a ball passes a specific position is obtained. Is used to determine the hit mode, the timing is dominated by contingency, and the value used is more contingency. For this reason, regularity is eliminated, and a pachinko machine with higher entertainment can be obtained.
