Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ball game machine such as a pachinko machine,
More specifically, the present invention relates to a ball game machine including a starting opening for starting another game by winning a game ball shot on a game board surface 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 a pachinko game machine that gives a player a great profit, that is, a lot of prize balls by opening a variable winning device called a tulip or an attacker according to a result mode when stopped after a certain time. Has been. 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, if the nail near the starting opening is adjusted or the starting opening is arranged at a position where the game ball is difficult to win, especially for a specific player called a professional, the skill is poor. The player cannot play another game, and as a result, there is a large difference in the number of prize balls to be obtained depending on the skill of the player, and there is a problem that the game for general persons lacks 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 having a mouth and another game device for performing another game in which a predetermined number of prize balls are given when a game ball wins, every time a predetermined number of game balls are shot from the launch device. A launch ball detecting means for detecting it, a random number generating means for generating a random number, a determining means for determining the value of the random number generated by the random number generating means, and the random number according to a detection signal from the launch ball detecting means. When the first random number generated by the generating means is a predetermined value, the starting opening is converted into the second state until a predetermined number of game balls are won, and at the same time, another game is started by winning the starting opening. Continuation by the second random value Constant and, in case of continuing the separate game is characterized in that a control means for determining a number of possible winning gaming balls by the third random value during its continuation.

As another gaming device, for example, a pair of wings is closed and a game ball cannot be won, and the wings are opened to convert the game ball into a winning state, and a predetermined number of game balls are won each time the game ball is won. A prize winning device that is set so that prize balls are paid out,
An indicator for indicating the continuation of the opening / closing operation of the winglet is provided.

[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 generated as the first 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 includes not only the case where the second state is continued, but also the case where the first state and the second state are alternately repeated. When a predetermined number (for example, one) of game balls wins the starting opening during this conversion drive, the other game device is caused to start another game,
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, a second random number value is determined in order to determine whether or not to continue the another game started by winning the prize at the starting opening. The second random number may be generated separately from the first random number, but the random number generated by the random number generating means may be shared by the first random number and the second random number. In that case, the range for determining the random value is made different. That is, when the value of the generated random number falls within the first range, it is determined that the first random number has been hit, and when it falls within the second range different from this, the second random number has been hit.

When another game is continued by the determination of the second random number value, the number of game balls that can be won at the time of the continuation is determined by the third random number. The third random number may also be generated separately from the first and second random numbers, but the random number signal generated by the random number generating means may be the first random number, the second random number, or the third random number as necessary.
The random numbers may be used separately.

When another game is to be continued a predetermined number of times by the determination of the third random number value, the number of game balls that can be won is determined for each continuous game, and a prize ball given to the player as the result of those games. Is preset.

As described above, the conversion of the starting opening to the second state, the determination of the continuation of another game started by the winning of the starting opening, and the number of game balls that can be continuously won in another playing are determined by a predetermined disorder. Since each is determined by the probability of the appearance of a numerical value, the player is equally given the opportunity to win a prize at the starting opening and the opportunity to win a prize ball by another game. You can manage the rate.

Further, when a prize winning device having a pair of wings and a display indicating the continuation of the opening and closing operation of the wings are provided as another game device, the player can recognize the fun of the continuous game that brings great profits. be able to.

[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. In the center of the game board surface 2, a big winning device 4 for performing another game in which a predetermined number (for example, 13) of prize balls is given when a game ball wins is arranged, and another game continues below it (see below). Jackpot)
A variable display 5 for displaying whether or not it is provided.

It should be noted that on the game board surface 2, a large number of nails 6 are arranged as a stabilizing means for guiding the launched game ball 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 a game ball launching device, for example, as shown in FIG.
The one that causes the plunger 10 to project by the electromagnetic force of the solenoid 9 and causes the game ball P to pop out is used. At the time of operation, the game ball P is sent to the plunger protruding side, and the solenoid 9 is energized to shoot the game ball P forward at the tip of the plunger 10.

A launch ball sensor 14 is arranged in front of the launch device in order to detect each game ball P launched from this launch device. The launch ball sensor 14 is composed of a magnetic sensor having a hole through which the launched game ball P can pass, and its output is sent to a launch ball counter 18.

The game ball P launched from the launching device 9 is a launch ball passage 15
Although it goes up and goes along the guide rail 8 toward the game board surface 2, the return ball P ′ that has returned to the launcher without reaching the game board surface 2 falls into the recovery path 16. A return ball sensor 17 for detecting this is arranged in the middle of the recovery path 16, and the output of the return ball sensor 17 is sent to the return ball counter 19. As a result, a game ball (return ball) that has returned to the launch device without reaching the game board surface 2 is not counted as a launch ball.

The above-mentioned launch ball counter 18 and return ball counter 19 are
Connected to the circuit of FIG. The launch ball counter 18 increases the count value by 1 when the launch ball sensor 14 detects the game ball P, and the return ball counter 19 increases the count value by 1 when the return ball sensor 17 detects the return ball P '. .

The circuit shown in FIG. 5, which will be described later, generates a first random number in response to detection signals from the launch ball counter 18 and the return ball counter 19, and forms a starting opening when the random number value reaches a predetermined number. The variable prize winning devices 3L, 3C, 3R are converted and driven to the second state advantageous to the player, and when the game ball wins in any of them, the conversion driving is stopped and the variable prize winning devices 3L, 3R.
The C and 3R are returned to the first state. If a predetermined number (for example, one) of game balls does not win during these conversion drives, the next conversion drive is performed until a predetermined number of two culture balls (for example, two) game balls are won.

The conversion driving of the starting port as described above may be continuous or continuous. In addition, as a method of driving the plurality of variable winning apparatuses, there is a method of converting and driving all of the variable winning apparatuses all at once, or a method of converting and driving each of the winning apparatuses one by one into two states. According to this method, the winning opening to be converted is circulated, and while the display is interesting, the variable winning device that is being converted is stopped when a predetermined number of game balls are won. Compared to the case where all of the variable winning devices are stopped at the same time, the change of all the variable winning devices is small, which is visually desirable.

Variable winning device 3L, 3C and 3 forming the above-mentioned starting opening
R is configured as shown in FIG. 3, for example.

First, a pair of arcuate curved movable pieces 42a and 42b are rotatably arranged on the front side of the game board, and a lower portion thereof is covered with a cover member 43. When the pair of movable pieces 42a and 42b are closed as shown in FIG. 3 (A), the variable winning device is in the first state in which the game ball cannot be won, and when it is opened as shown in FIG. 3 (B). It becomes the second state in which the game ball can win.

A bracket 45 accommodating a solenoid 44 is attached to the back side of the game board. Circular engagement plates 47 and 48 are fixed to the upper and lower ends of the plunger 46 protruding from the upper and lower sides of the solenoid 44, and the circular disc 47 at the upper end and the bracket 4 are fixed.
A coil spring 49 is arranged between the upper surface of the coil 5 and the upper surface of the coil 5. When the solenoid 44 is energized and excited, the lower end of the plunger 46 projects downward from the state of FIG. 3 (A).
Then, when the energization is stopped and the solenoid 44 is demagnetized, the plunger 46 is returned to the original state by the force of the coil spring 49. The variable winning device uses the movement of the plunger 46 to open and close the pair of movable pieces 42a and 42b.

Each of the pair of movable pieces 42a, 42b has a cylindrical base portion, and is rotatably supported inside the cover member 43 by an eccentric shaft 51 provided on the front side of each base portion. Each movable piece 4
A motion transmission member 52 that converts the vertical reciprocating motion of the plunger 46 into the opening / closing motion of the movable pieces 42a and 42b is provided between the bases of the 2a and 42b and the solenoid 44. The motion transmitting member 52 is mainly composed of a rectangular plate, and is rotatably supported by supporting portions 41a and 41b extending to the left and right rear of a mounting plate of the variable winning a prize device, with projections 53a and 53b provided on the left and right end surfaces thereof serving as fulcrums. It Further, the motion transmitting member 52 has an L-shaped convex portion 54 that sandwiches the disc 48 below the solenoid on the back side, and a pair of front side extending to the bases of the corresponding movable pieces 42a and 42b. It has transmission rods 55a and 55b. The tip of each transmission rod 55a, 55b is formed thin,
Hole 56 provided on the back side of the base of each movable piece 42a, 42b
It is slidably inserted into a and 56b.

Between the bases of the pair of movable pieces 42a, 42b, there is arranged a winning ball receiving portion 58 having a triangular convex portion 57 which receives a game ball won when both the movable pieces are opened and is directed backward.
A gutter 59 for discharging the winning balls is provided on the lower rear side thereof. The winning ball receiving portion 58 receives the winning ball and also receives the winning ball.
When 2a and 42b are opened, the pair of movable pieces 42a and 42b are opened as shown in FIG. 3B by locking the convex 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. 3 (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. The motion transmission member 52 rotates, and the transmission rods 55a and 55b.
As a result of lifting up, the pair of movable pieces 42a and 42b are opened to the left and right, and the respective lower protruding pieces 60 are
It stops when a and 60b hit the winning ball receiving portion 58.
As a result, the game balls can be won, and the prize balls are discharged from the prize ball receiving portion 58 through the gutter 59 into the prize ball passage.
On the other hand, when the energization is stopped and the solenoid 44 is demagnetized, the force of the coil spring 49 returns the plunger 46 to the original state. By the upward movement of the plunger 46, the motion transmission member 52 rotates in the opposite direction to the above, and the transmission rod 55a,
Lower 55b. As a result, the pair of movable pieces 42a, 42
The state of b is closed.

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

First, the special winning device 4 is configured as shown in FIG.
That is, a pair of wings 21a, 21b on the front side of the game board
Is arranged so as to be openable and closable, and a sensor 22 for detecting passage of a game ball (winning ball) and a winning opening 23 are arranged therebetween. The sensor 22 and the winning opening 23 are covered with an appropriate cover member. In the big winning device 4, the pair of wing pieces 21a and 21b is the first
When the game ball is closed as shown in the figure, it is in the first state in which the game ball cannot be won, and when the pair of wings 21a, 21b are opened to the left and right, the game ball is in the second state in which the game ball can pass through the sensor 22 and enter the winning opening 23. . The game ball entering the winning opening 23 is the sensor 2
A known prize-ball payout device incorporated in a pachinko gaming machine detects a predetermined number (for example, 13) of prize balls according to the detection signal.

The pair of wings 21a and 21b are opened and closed by a mechanism similar to that of the variable winning a prize device of FIG. That is, although each solenoid 44 is closed when it is not driven,
When the solenoid 44 is energized and excited, the spring 49
The plunger 46 is lowered against the
The convex portion 54 of the motion transmitting member 52 is pushed down via. Therefore, the motion transmitting member 52 rotates, and the transmission rod 55 on the front side.
As a result of lifting a and 55b, the wing pieces 21a and 21b open to the left and right, and the lower convex pieces 60a and 60b stop 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, when the energization is stopped and the solenoid 44 is demagnetized, the force of the coil spring 49 returns the plunger 46 to the original state. As a result, the pair of blades 21a and 21b are closed.

In addition, above the big winning device 4, a display 24 composed of a 7-segment LED (light emitting diode) for displaying the number of gaming balls won in the winning opening 23 is arranged.

On the other hand, the variable display 5 is a light emitting body 5a such as an LED or a light bulb,
It is formed by arranging a plurality of (for example, 6) 5b, ... During the game, the variable display 5 is driven so that each light emitting body is sequentially turned on, but as will be described later, a pair of wing pieces 21 of the large winning a prize device 4 is accompanied by winning a prize at the starting opening.
If the light-emitting body 5c at the center of the ellipse is turned on when the game balls pass through the sensor 22 when opening and closing a and 21b are started, another game in which a predetermined number (for example, 10) of game balls are received in the winning opening 23 Is continuously performed a predetermined number of times (for example, 8 times). Therefore, the variable display 5 is used as a means for indicating to the player whether or not another game is to be continued. However, the continuation of another game itself is, as will be described later in detail, the second number generated by the random number generation means due to the winning of the starting opening.
The random number is determined to be a predetermined value (corresponding to a lottery).

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

As shown in FIG. 5, a random number generator 31 that generates a random number according to the output signals a and b from the above-mentioned launch ball counter 18 and return ball counter 19, and a determiner 32 that determines the value of the generated random number. And when the value of the first random number generated by the random number generator 31 is a predetermined value, the variable winning device 3 which is the starting port
L, 3C, 3R is converted to the second state until the game ball wins in one of them, and the opening and closing operation (separate game) of the big winning device 4 which is started by winning the start opening is continued.
If you decide on the random number of, and continue another game,
A control unit 33 that determines the number of game balls that can be won when the game continues is provided with a third random value.

On the other hand, a winning ball sensor 34 and a winning ball counter 35 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 34 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 each variable winning device passes through the hole. Of course, a sensor (optical sensor, microphone switch, etc.) other than the magnetic sensor may be used. The detection signal of the winning ball sensor 34 is input to the winning ball counter 35, and the number of winning balls is counted by this. The count value is sent to the control unit 33. Further, in order to count the game balls detected by the passage sensor 22 while the big winning device 4 is opening and closing the pair of wings, a prize ball counter 36 of another game is provided, and the count value is also controlled. Sent to section 33.

Further, on the output side of the control unit 33, the variable winning device 3L, 3L.
A drive unit 37 for driving C and 3R, and a drive unit 38 for driving the special winning device 4 for another game, the prize number indicator 24 and the continuation determination indicator 5 are provided.

The operation of the circuit of FIG. 5 is as follows.

First, the random number generation unit 31 performs a predetermined calculation every time the firing ball counter 18 counts 1 to generate a (first) random number. However, on condition that the value of the return ball counter 19 is 0, if the count value is 1 or more, a random number is not generated. For example, when the count of the return ball counter 19 is 2, the launch ball counter 1 starts from the time when it is counted.
The count output of 8 is passed twice (random numbers are not generated). 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 first random number generated by the random number generator 31 falls within a predetermined range, the starting opening is converted and driven into the second state advantageous to the player as described above, but the probability is It is defined as follows. For example, the range of random numbers is 1
When set to ~ 4096, the range of random value that opens the starting port is 1
When set to ˜136, the probability of converting and driving the starting port to the second state is about 1/30.

The determination unit 32 determines whether or not the value of the first random number generated by the random number generation unit 31 falls within the range defined as above.

When the first random number determined by the determination unit 32 has a value that opens the starting port, the control unit 33 sends a drive signal to the drive unit 37 that converts and drives the movable pieces of the variable winning award devices 3L, 3C, 3R, and outputs these signals. Solenoid 4 so that the variable winning device is in the second state
4 is driven. During this conversion driving, when the game ball wins any of the variable winning devices and the counter 35 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 35 reaches a predetermined value by winning the game ball at the starting opening (if the value is 1, the gaming ball wins), the control unit 33 causes the drive unit 38 to the solenoid of the big winning device 4. A signal for driving 44 is sent to start another game by opening and closing the pair of wing pieces 21a, 21b. The opening / closing operation (once) of the wing pieces is performed until a predetermined number (for example, 10) of game balls are won in the winning opening 23. Each time a game ball wins the winning opening 23, the control unit 33 sends a signal to a prize ball payout device (not shown), and a predetermined number (for example, 13).
The prize balls for each item are paid out.

On the other hand, the determination unit 32 determines the second random number value generated by the random number generation unit 31 along with the winning of the starting opening. As a result, the second
When the value of the random number of hits a predetermined number, another game is continued (big hit). The probability of continuing this separate game is determined as follows. For example, if the range of random numbers is 1 to 4096, and the range of the second random number value to be continued is 1001 to 1082, the probability of continuation is about 1/50.

As a result of the determination of the second random number value, when it is not continued, the opening / closing operation of the pair of wing pieces of the special winning device 4 is performed once,
That is, the process ends when a predetermined number (for example, 10) of game balls enter the winning opening 23.

On the other hand, when another game is continued, the opening / closing operation of the pair of wing pieces of the special winning device 4 is performed a predetermined number of times (for example, 8 times).
To do. In this case, the control unit 33 sends a signal to the drive unit 38 to stop the circulation lighting of the display 5 in the light emission state 5c at the upper center when the sensor 22 detects the passage of the game ball.
Furthermore, the number of game balls (the number of winning prizes) to be received in the winning opening 23 is determined by a random number for each continuous operation. for that reason,
Before the next continuous operation starts, the determination unit 32 determines the value of the third random number generated by the random number generation unit 31, and according to the result, the number of game balls to be received in the winning opening 23 in the next continuous operation. To set.

For example, the range in which the third random number is generated is set to 1 to 160, the number of possible prizes for each time when another game is continued is set to 4 to 10, and the range of the random number value corresponding to each possible number of prizes is as follows. Set.

In the embodiment, 13 prize balls are paid out each time a game ball wins the winning opening 23, and another game is continued eight times. In the above example, the number of prizes that can be won at each time is seven. Since the number is the largest, the number of prize balls paid out by continuing another game is 13 × 7 × 8 = 728 on average.

Thus, by appropriately adjusting the range where the third random number hits, the number of prize balls that the player can obtain can be arbitrarily set when continuing another game.

In the circuit of FIG. 5, a random number generator 31 and a determiner 32
Are configured as a single random number generating means and a determining means, respectively, and are configured by three sets of random number generating circuits and determining circuits for separately generating the first, second and third random numbers and determining their values. May be.

Further, the random number generated by the random number generator 31 may be determined as the first random number, the second random number, or the third random number as necessary. In that case, if the value of the determined random number falls within the range of the first random number, the starting opening is converted and driven, and if it falls within the range of the second random number, another game is continued and the range of the third random number is reached. For example, the corresponding number of winning balls will be accepted in the special winning device. Therefore, a storage unit (memory) 39 for storing the initially generated random number value is provided and connected to the control unit 33.

Further, in FIG. 5, a block 40 surrounded by a chain line
Each part inside can be configured by a known electronic circuit,
A microcomputer may execute these operations. In this case, the microcomputer executes the following operations.

As shown in the flowchart of FIG. 6, if there is a shot ball count output (this is generated every time a game ball is shot), a first random number is generated, and when that value hits the lottery, a flag Set 1 to open and close the starting port. That is,
A signal for continuously converting and driving the variable winning devices 3L, 3C, 3R to a second state advantageous to the player is output, and when any of the variable winning devices wins a game ball, the conversion driving is stopped. Even if the flag 1 is set, if the game ball does not win, the flag generated in the next lottery is set to 2 and the variable winning device is driven for conversion 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.

Further, when a prize is awarded to the starting opening, a second random number is generated and the special winning apparatus 4 is caused to start the opening / closing operation of the wing pieces. Further, it is determined whether or not the value of the second random number is a big hit, and in the case of a big hit, the circulation lighting of the display 5 with respect to the output of the sensor 22 is not stopped at the light emitting body 5c at the upper center, but a connector is used. Return to the first step as shown.

On the other hand, when a big hit occurs, a flag corresponding to the big hit is set and the circulation lighting of the display 5 is stopped by the light emitting body 5c in the upper center with respect to the output of the sensor 22. As a result, the decision to continue playing the game is displayed. At this time, in order to confirm that the game ball has won the winning opening 23, a sensor may be provided at the winning opening 23 to check the output. Then, the game continuation operation is started.

The game continuation operation is performed as shown in FIG. First, a third random number is generated, and the number of possible winning prizes in the first continuous game is determined by the value thereof. After that, the winning hole 23
When a game ball wins, the number of prizes is counted and the cyclic lighting of the display 5 is set at an appropriate position (also determined by a random number).
Stop at. Then, it is determined whether or not the number of winning game balls has reached the number of winning prizes. If “No”, the next prize ball is waited for, and if there is a prize ball, the above operation is repeated. After that, when the number of possible winnings is reached, the number of continuations is counted, and if the count value is not one before the predetermined number of continuations (seventh in this case), return to the first step as shown by the connector. Determine the number of possible winnings for the next round and continue playing. When the number of continuations reaches the 7th time, that is, when the 7th continuation game is over, the next (8th) continuation game is the next, but in this example, the final possible winning number is the maximum 10
By fixing it to an individual, all players are given 10 winning opportunities (10-count game). Therefore, the possible winning number is not determined by the third random number.

By using the microcomputer as described above and setting the flag, it is possible to execute the state conversion of the starting opening, the continuation determination of another game, and the winning number setting at the time of continuation with a predetermined probability. Also, when the next flag is set, such as when the starting opening is converted to the second state or when another game is being performed, that is stored, and after the result of the other game is displayed, other necessary Sometimes it is possible to perform an action depending on the state of the flag.

The variable winning devices 3L, 3C, 3R of the embodiment have a state in which the game ball cannot be won by closing the pair of movable pieces, but the first state of the variable winning device used in the present invention is The gaming ball may be in a state where it is difficult to win the prize (the winning is difficult if not impossible). 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 34. At that time, the microcomputer sets the flag to -1, and cancels it with the flag 1 generated in the subsequent lottery.

Although the embodiment has been described above, the present invention is not limited to this. For example, the structure and arrangement of the starting port are arbitrary, and as the other game device, any device other than the special winning device of the embodiment can be used. Alternatively, one winning device may be divided in time and used as a starting opening at one time and as a winning opening at another time. Further, the continuous display of another game is not limited to the lighting system of the predetermined position as in the embodiment, but LE of 7 segments
You may make D display a specific number.

Furthermore, the present invention can be applied not only to pachinko game machines but also to ball game machines such as smart ball machines and sparrow ball game machines.

[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, the number of game balls that can be won and the continuation of another game started by winning at the starting mouth is also determined by random numbers respectively, so the probability of the state conversion of the starting mouth and the continuation of another game is set appropriately. Can be adjusted. Therefore, the players are equally given an opportunity to win a big profit by winning a prize at the starting mouth and continuing another game.
There is an effect that the player can enjoy the ball game regardless of the skill of the player, and that the winning rate can be managed in the game hall without the conventional nail adjustment.
