More specifically, the present invention relates to a ball game machine having a starting opening for starting another game when a game ball shot on the game board surface wins and another game device for performing another game.

[Prior Art] Conventionally, when a game ball shot on a game board surface wins a winning opening called a starting opening, another game is started by a variable display device provided on the game board surface, and the variable display is stopped by the player. There is known a pachinko gaming machine which gives a player a chance to make a great profit by opening a variable winning device called a tulip or an attacker in accordance with a result mode when the game is stopped after a certain period of time. In this type of pachinko gaming machine, in order to give many players an opportunity to obtain a profit by another game, the result mode of another game appears based on a preset probability.

[Problems to be Solved by the Invention] However, even if a result mode of another game that brings great profits to the player appears with a certain probability as described above, another game is started unless the game ball enters the starting opening. No, the winning of the starting mouth is not guaranteed. Further, in the above-mentioned pachinko machine, especially for a specific player called a professional, if the nail near the starting opening is adjusted or the starting opening is arranged at a position where the game ball is hard to win, the skill is poor. The player cannot play another game, and as a result, there will be a large difference in the number of prize balls won depending on the skill of the player.
There was a problem that the game for the general public lacked equality.

The present invention has been made in view of such problems,
It is an object of the present invention to provide a ball game machine which gives an opportunity of winning a prize ball by another game with equal probability regardless of the skill of a player and which does not require conventional nail adjustment.

[Means for Solving the Problem] The present invention relates to a launching device for launching a game ball onto a game board surface,
With respect to the winning of the game ball emitted from the launching device, it is formed so as to be convertible into a first state that is disadvantageous to the player and a second state that is advantageous to the player, and a start is made to start another game when the game ball wins. In a ball game machine equipped with a mouth and another game device for performing another game, a launch ball detection means for detecting each time a predetermined number of game balls are launched from the launch device, and a random number is generated. Random number generating means, determining means for determining the value of the random number generated by the random number generating means, and the value of the random number generated by the random number generating means in response to the detection signal from the launch ball detecting means is determined to be the predetermined value. Then, the starting opening is converted into the second state until a predetermined number of game balls are won, and another game started by winning the starting opening corresponds to the value of the random number generated separately from the random number. Play separately to end in the result mode Characterized in that a control means for controlling the device.

As one aspect of the present invention, the random number generating means includes a first random number generating section for generating a random number in response to a detection signal from the launch ball detecting means, and a second random number generating means for generating a random number separately from the random number. And part.

Further, on the game board surface, a variable winning device is provided which becomes advantageous to the player when another game ends in a specific result mode.

[Operation] In the ball game machine of the present invention, the random number generating means generates a random number each time a predetermined number (for example, one) of game balls are emitted from the emitting device, and the determining means determines the value. As a result, when the value of the random number is determined to be the predetermined value, the starting opening is converted and driven into the second state that is advantageous to the player. This conversion drive is
Not only the case where the second state is continued, but also the case where the first state and the second state are repeated alternately. When a predetermined number of game balls are won in the starting port during this conversion drive, another game is started in another gaming device, while the starting port is stopped in the first state. If a predetermined number of game balls are not won, it will be carried over to the next time.
That is, the next conversion drive is performed until the number of game balls including the carry-over amount is won. Further, the random number generation means generates a random number separately from the random number generated according to the detection signal from the launch ball detection means. Depending on the value of the random number, the result mode of the different game started by winning at the starting opening is determined, and the different game ends in the result mode.

As described above, the result mode of the different game started by the conversion of the starting opening to the second state and the winning in the starting opening is determined by the probability of occurrence of a predetermined random number value for a predetermined number of launch balls. Since each is decided, the player is equally given the opportunity to win a prize at the starting opening and the profit according to the result mode of another game, and the award rate is managed in the amusement hall without the conventional nail adjustment. You can

Further, when the variable winning device is provided, a specific result mode of another game for converting it into a state advantageous to the player is determined by the value of the random number generated by the random number generating means, and the random number value is predetermined. Appears with a probability. Therefore, the opportunity to change the state of the variable winning device, which brings great profits to the players, is equally given.

[Embodiment] FIG. 1 is a front view of a pachinko gaming machine which is an embodiment of the present invention. On the gaming board surface 2 of this pachinko gaming machine 1,
As a starting opening for starting another game when a game ball wins, a variable winning that is converted into a first state in which a game ball launched from the launching device described later on the game board surface 2 cannot win and a second state in which it can win The devices 3L, 3C, 3R are arranged in each of the left, center, and right parts. A variable display device 4 for performing another game is arranged in the center of the game board surface 2, and a variable prize device 5 having a door that opens when a result of the other game is in a specific display mode is provided below the variable display device 4. ing.

It should be noted that on the game board surface 2, a large number of nails 6 are arranged as a guide means for guiding the shot game balls to the upper part of the variable winning device, while a ball hitting handle 7 is provided on the lower right side of the front face, and When this is operated, a game ball is launched from a launching device attached to the back side of the game board and moved along the guide rail 8 on the game board surface 2.

As the game ball launching device, for example, the one shown in FIG. 2 is used. The launching device 9 includes a ball launching portion 11 including a solenoid that causes the plunger 10 to project by an electromagnetic force so as to project the game ball P, and a hitting ball guide portion 12 provided on the plunger projecting side. The hitting ball guide portion 12 is formed of a cylindrical member having a notched end portion for feeding the game ball P, and a pair of guide members 12 for guiding the game ball P flipped by the tip end of the plunger 10 forward on the inner bottom surface thereof. It has parallel ribs 13.

Further, since each time a game ball P is launched from the launching device 9, it is detected, the launch ball sensor 1 is provided in front of the launching device 9.

When 2a and 42b are opened, the pair of movable pieces 42a and 42b are opened as shown in FIG. 4B by locking the protruding pieces 60a and 60b protruding downward from the base of each movable piece. Has the function of holding in.

In the variable winning device 3L, 3C, 3R having the above-mentioned configuration, the pair of movable pieces 42a, 42b are closed as shown in FIG. 4 (A) when the respective solenoids 44 are not driven. Here, when the solenoid 44 is energized and excited, the plunger 46 is lowered against the spring 49, and the convex portion 54 of the motion transmission member 52 is pushed down via the disk 48 at the lower end thereof. Therefore, the motion transmitting member 52 rotates to lift the front transmission rods 55a and 55b. As a result, Fig. 4 (B)
As shown in, the pair of movable pieces 42a and 42b are opened to the left and right, and the lower convex pieces 60a and 60b are stopped when they hit the winning ball receiving portion 58. As a result, the game balls can be won, and the winning balls are discharged from the winning ball receiving portion 58 through the gutter 59 into the winning ball passage. On the other hand, stop energizing the solenoid 4
When 4 is demagnetized, the plunger 46 is returned to the original state by the force of the coil spring 49. By the upward movement of the plunger 46, the motion transmission member 52 rotates in the opposite direction to the above, and the transmission rods 55a and 55b are lowered. As a result, the pair of movable pieces 42a and 42b are closed.

In this embodiment, the variable winning device as described above is used as the starting port for starting another game, but other winning devices may be used. For example, by making a bar-shaped winning restriction member appear and disappear above a winning opening provided on the game board surface, a first state in which a gaming ball cannot or is difficult to win in the winning opening, and a second state in which a gaming ball can win. Between the position where the game ball cannot win or is difficult to win the prize hole (first state) and the position where the game ball can win (second state). Those that are movably formed can be used.

Next, the variable display device 4 and the variable winning device 5 for another game provided on the game board surface 2 will be described.

As shown in FIG. 5, the variable display device 4 has a front portion 32 mounted on the game board surface 2, a pair of left and right small windows 33L and 33R are provided on the upper portion of the front portion 32, and a large window is provided on the lower portion. 34 are provided. In the small windows 33L and 33R, indicators 35L and 35R composed of 7-segment LEDs (light emitting diodes) for variably displaying numbers are arranged, and in the large window 34, a part of the peripheral surface of the cylindrical reel 36. Are arranged so as to appear. The reel 36 is rotationally driven in one direction by a reel drive unit 37 having a pulse motor as a drive source, with a central axis of the reel 36 placed horizontally as a fulcrum. On the peripheral surface of the reel 36, a sheet on which a plurality of (for example, 10) symbols are printed is mounted. The reel drive unit 37 is used for the reel 3
When the rotation of 6 is stopped, the reel 36 is positioned so that one of the symbols of the sheet wound on the peripheral surface thereof can be housed in the large window 34 of the front portion 32. A drive circuit 38 controlled by an output signal from the control unit 25 shown in FIG. 6 is connected to the display devices 35L and 35R and the reel drive unit 37.

On the other hand, the variable winning device 5 is called an attacker, and has a door of substantially the same shape that is openably and closably attached to the front side of the opening provided in the upper part of the trapezoidal front plate, and has a winning opening in the opening.
The door of the variable winning device 5 is opened and closed by a drive mechanism having a solenoid as a power source attached to the back side of the front plate.

Next, the electric circuit section of the embodiment will be described.

As shown in FIG. 6, a first random number generator 21 for generating random numbers according to the output signals a and b from the launch ball counter 18 and the return ball counter 19 which form the above-described launch ball detection device 20, A first determination unit 22 that determines the value of the generated random number, a second random number generation unit 23 that generates another random number when the determined random number is a predetermined value, and a second determination unit that determines the value of the random number. When the random number value determined by the determination unit 24 and the first determination unit 22 is a predetermined value, the variable display devices 3L, 3C, 3R are converted into the second state until a predetermined number of game balls are won in one of them. At the same time, a control unit 25 for controlling the variable display device 4 is provided so that another game started by winning a prize in the starting opening is finished in a result mode according to the random number value determined by the second determination unit 24. .

Further, a winning ball sensor 61 and a winning ball counter 62 are provided as winning ball detecting means for detecting when a game ball enters any of the variable winning devices 3L, 3C, 3R. The winning ball sensor 61 is composed of a magnetic sensor having a hole through which the gaming ball passes, and detects the winning ball from the change in the magnetic field when the gaming ball exiting from each variable winning device passes through the hole. Of course, a sensor (optical sensor, micro switch, etc.) other than the magnetic sensor may be used. The detection signal of the winning ball sensor 61 is input to the winning ball counter 62, where the number of winning balls is counted. Furthermore, each variable winning device 3L, 3C,
Drive circuit 6 for driving the solenoid 44 described above for each 3R
3 is provided.

The variable winning device (attacker) 5 is provided with an attacker winning ball sensor 71 and a winning ball counter 72 as means for detecting a game ball that has won an internal winning opening. The winning ball sensor 71 is composed of the same magnetic sensor as the above-described winning ball sensor 61, and is arranged in the winning ball discharging passage of the attacker. The detection signal from the attacker winning ball sensor 71 is input to the winning ball counter 72, where the number of winning balls is counted. Furthermore, the solenoid 73 for driving the attacker door
A drive circuit 74 for driving the is provided.

In the circuit of FIG. 6, the first random number generator 21 performs a predetermined calculation every time the firing ball counter 18 counts 1 to generate a random number. However, if the value of the return sphere counter 19 is 0, and the count value is 1 or more, no random number is generated. For example, when the count of the return ball counter 19 is 2, the count output of the firing ball counter 18 is passed twice (no random number is generated) from the time when it is counted. Then, the signal c that counts down the return ball counter 19 to 0 is output for that number of times.

When the value of the random number generated by the random number generator 21 reaches a predetermined number, the starting opening is converted into the second state advantageous to the player as described above, and the probability is as follows. Stipulated in. For example, the range of random numbers is 1 to 409.
When set to 6, the range of the random number value that opens the starting port is 1-273
If so, the probability of driving the starting port to the second state is about 1
It will be one fifth.

The first determination unit 22 determines whether the value of the random number generated by the first random number generation unit 21 falls within the range defined as above.

When the random number determined by the first determination unit 22 is a value that opens the starting opening, the control unit 25 sends a drive signal to the drive circuit 63 that converts and drives the movable pieces of the variable winning award devices 3L, 3C, 3R, and outputs these signals. The solenoid 44 is driven so that the variable winning device is in the second state. During this conversion drive, when the game ball wins any of the variable winning devices and the counter 62 outputs,
The variable winning device is returned to the first state, which is disadvantageous to the player, and stopped.

Further, when the winning ball counter 62 reaches a predetermined value due to the winning of the gaming ball at the starting opening (if the value is 1, the gaming ball wins), the control unit 25 sends a signal to the drive circuit 38 of the variable display device 4. To start another game. On the other hand, the second random number generator 23 generates a random number,
The determination unit 24 determines. As a result, when the value of the random number hits a predetermined number, the different game is ended in a specific result mode (for example, a big hit), and the probability of the specific result mode is determined as follows. For example, if the range of random numbers is 1 to 4096, and the range of random numbers to be a big hit is 1001 to 1012, the probability of a big hit is about 1/341.

Thus, if the result mode of another game is a big hit, the control unit 2
5 sends a signal to the drive circuit 38 to stop the variable display device 4 with a big hit display, and also sends a signal to the drive circuit 74 of the variable winning device 5 to open the door for a certain period of time.

In addition, in the case of a hit other than a big hit or a miss (probability is determined by the range of random number values set corresponding to each)
In, the other game device 4 is stopped at the display corresponding to it,
In case of winning, a predetermined number of prize balls are paid out.

In the circuit of FIG. 6, the first and second random number generators 21,
The 23 and the first and second determining units 22 and 24 may be configured as a single random number generating means and a single determining means, respectively.
Further, the random number generating unit, the determining unit, and the control unit described above can be configured by known electronic circuits, respectively, but a microcomputer may execute these operations.

In that case, the microcomputer is configured to have a predetermined number (eg, 1
Each time a game ball is shot, a random number is thrown, and when the value hits the lottery, that is, when the starting opening is opened, flag 1 is set. And the variable winning device 3L, 3
A signal for continuously or continuously converting and driving C and 3R to a second state advantageous to the player is output, and the conversion driving is programmed to be stopped when a game ball is won in any of the variable winning devices. . If the game ball does not win even if the flag 1 is set, the flag generated in the next lottery is set to 2 and the variable prize winning device is converted and driven until the number of game balls to which the carry-over amount is added is won. Further, when the flag 1 is standing and, for example, two game balls have been won in the starting opening, the flag is set to -1 to offset the flag 1 generated in the next lottery. On the other hand, when the value of the random number generated by the second random number generator 23 hits a big hit, a flag corresponding to it is set.

By the way, the variable winning devices 3L, 3C, 3R of the embodiment,
The first state is a state in which the game ball cannot be won by closing the pair of movable pieces. However, in the first state of the variable winning device used in the present invention, it is difficult for the game ball to win (though it is not impossible to win). It may be in a (difficult) state. In that case, even if the variable winning device is in the first state, that is, when the flag 1 is not set, the game ball may win the variable winning device, but such a winning is a prize. It is detected by the ball sensor 61. At that time, the microcomputer sets the flag to -1, and cancels it with the flag 1 generated in the subsequent lottery.

By using the microcomputer as described above and setting the flag, the state conversion of the starting opening and the result mode of another game can be executed with a predetermined probability.
In addition, when the starting opening is converted to the second state, when another game is being performed, or when the attacker is open depending on the result mode of the other game, when the following flag is set, It can be stored, and after the result of another game is displayed, the operation according to the state of the flag can be executed when necessary.

Although the embodiments have been described above, the present invention is not limited to pachinko game machines, but can be applied to smart ball machines, sparrow ball game machines, and other ball game machines. Further, the structure and the arrangement of the starting port are arbitrary, and as the other game device, any one other than the variable display device of the embodiment can be used.

[Effects of the Invention] As described above, the ball game machine of the present invention converts the starting opening into a state advantageous to the player according to the value of the random number generated each time a predetermined number of game balls are shot. Along with this, since the result mode of the separate game started by winning the start opening is also determined by a random number, it is possible to adjust the state conversion of the start opening and the probability of the result mode of the separate game. Therefore, the players are equally given an opportunity to win a prize at the starting opening and to obtain a profit according to the result mode of another game, and can enjoy the ball game regardless of the skill of the player and the game hall. In, there is an effect that the winning rate can be managed without the conventional nail adjustment.
