Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to pinball game machines such as pachinko machines,
More specifically, the present invention relates to a pinball game machine equipped with a starting port for starting another game when a game ball shot onto the game board surface wins, and a separate game device for playing the other game.

[Prior Art] Conventionally, when a game ball launched onto a game board enters a winning hole called a starting hole, another game is started using a variable display device provided on the game board, and the variable display is controlled by a player's stop operation. A pachinko game machine is known that gives a player an opportunity to obtain a large profit by opening a variable prize winning device called tulip or attack depending on the result when the game stops at a winning combination or after a certain period of time has passed. In this type of pachinko game machine, in order to give many players the opportunity to earn profits through different games, the results of different games appear based on preset probabilities.

[Problems to be Solved by the Invention] However, even if the results of the separate game that bring a large profit to the player appear with a certain probability as described above, the separate game will not start until the game ball enters the starting hole. not,
Wins in the starting slot are not guaranteed. In addition, in the pachinko machines mentioned above, if the nails near the starting hole are adjusted or the starting hole is placed in a position where it is difficult for the game ball to hit the prize for a certain player, especially a professional player, it is a sign of poor skill. Players cannot play different games, and as a result, there is a large difference in the number of prize balls won depending on the skill of the player, and there is a problem that there is a lack of equality as a game aimed at sailors. Ta.

The present invention has been made in view of such problems, and
To provide a pinball game machine which gives players an opportunity to win prize balls in another game with equal probability regardless of their skill, and which eliminates the need for conventional nail adjustment.

[Means for Solving the Problems] The present invention provides a firing device that fires a game ball onto a game board surface;
A trigger configured to be convertible into a first state disadvantageous to the player and a second state advantageous to the player regarding winning of the game ball fired from the firing device, and for starting another game when the game ball wins. A pinball game machine comprising a mouth and a separate game device for playing a separate game, including a shot ball detection means for detecting each time a predetermined number of game balls are shot from the shooting device, and generating a random number. a random number generating means for determining the value of the random number generated by the random number generating means; and an identifying means for determining the value of the random number generated by the random number generating means; At this time, the starting hole is driven to be converted to a second state until a predetermined number of game balls are won, and a separate game that is started by winning the starting hole corresponds to the value of a random number generated separately from the random number. The present invention is characterized by comprising a control means for controlling the separate gaming machine so that the gaming machine ends in the manner in which the game ends.

As one aspect of the present invention, the random number generation means includes a first random number generation section that generates random numbers according to a detection signal from the shot ball detection means, and a second random number generation section that generates random numbers separately from the random numbers. including the section.

On the other hand, a variable prize winning device is arranged on the game board surface, which becomes advantageous to the player when another game ends with a specific outcome.

[Function] In the pinball game machine of the present invention, a predetermined number of (
For example, a random number generating means generates a random number each time a game ball (for example, one game ball) is shot, and a determining means determines the value. As a result, when the value of the random number is determined to be the predetermined value 11α, the starting port is driven to be converted to the second state advantageous to the player. This conversion drive is applied not only when continuing the second state (but also when converting between the first state and the second state).
This also includes cases in which states are repeated alternately. When a predetermined number of game balls enter the starting hole during this conversion drive, another game is started in another gaming device, while the starting hole is stopped in the first state. If the predetermined number of game balls do not win, the conversion is carried over to the next time, that is, the next conversion drive is performed until the number of game balls added to the carryover amount is won.

Further, the random number generating means generates a random number separately from the random number generated in response to the H detection signal from the shot ball detecting means. The value of the random number determines the result pattern of the separate game that is started when a prize is won in the starting slot, and the separate game ends in this result pattern.

As mentioned above, the result of the separate game that is started by converting the starting hole to the second state and winning the starting hole is based on the probability that a predetermined random value will appear for a predetermined number of shot balls. Since each is determined, players are given an equal opportunity to win in the starting slot and to earn profits according to the results of other games, and in the gaming hall, the winning rate can be managed without the traditional adjustment of the nails. Can be done.

In addition, when a variable prize winning device is provided, the specific outcome of another game that converts this into an advantageous state for the player is determined by the value of a random number generated by a random number generating means, and the random value is a predetermined value. Appears with probability. Therefore, players are equally given an opportunity to change the state of the variable prize winning device, which brings great profits to the players.

Embodiment 1 FIG. 1 is a front view of a pachinko game machine which is an embodiment of the present invention. On the game board surface 2 of this pachinko game machine l,
A variable winning state in which a game ball fired onto the game board surface 2 from a firing device (to be described later) is converted into a first state in which it cannot win and a second state in which it can win, as a starting point for starting another game when the game ball wins. A variable display device 4 for playing different games is arranged in the center of the 8M skill board 2 where the devices 3L, 3C, and 3R are arranged on the left, center, and right, and below it, the results of the different games are displayed. A variable prize winning device 5 is provided which has a door that opens when a specific display mode is achieved.

In addition, a large number of nails 6 are arranged on the game board surface 21 as a guide means for guiding the launched game balls to the upper part of the variable prize winning device, while a ball hitting handle 7 is provided at the lower right side of the front, so that the player can When this is operated, a game ball is fired from a firing device attached to the back side of the game board and moves along a guide rail 8 on the game board surface 2.

As the game ball firing device, one shown in FIG. 2, for example, is used. This firing device 9 consists of a ball launching section 11 including a solenoid that causes a plunger 10 to project by electromagnetic force to cause a game ball P to fly out, and a ball hitting guide section 12 provided on the plunger protruding side. The ball-hitting guide section 12 is formed of a cylindrical member with a cut-out tip for feeding the game ball P, and has a pair of holes on its internal bottom surface that guide the game ball P bounced by the tip of the plunger IO forward. It is provided with parallel protrusions 13.

Further, in order to detect each time a game ball PtJ<1 is fired from the firing device 9, a firing ball sensor 14 is arranged in front of the firing device 9. This shot ball sensor 14 is composed of a magnetic sensor having a hole through which the shot game ball P can pass, and its output is sent to a shot ball counter 18 (FIG. 3), which will be described later.
sent to.

The game ball P fired from the firing device 9 passes through the firing ball passage 15 as shown in FIG. 3, rises along the guide rail, and heads toward the game board surface 2, but! The return ball P' that has returned to the firing device 9 without reaching the technique board surface 2 falls into the first recovery path 16. A return ball sensor 17 that detects this is placed somewhere along the recovery path 16, and the output of this return ball sensor 17 is sent to a return ball counter 19. This results in
A game ball (return ball) that returns to the firing device 9 without reaching the game board surface 2 is not counted as a fired ball.

The above launch ball sensor 14 and return ball sensor! 7. The fired ball counter 18 and the returned ball counter 19 constitute a fired ball detection device 20 connected to the circuit shown in FIG. Here, the fired ball counter 18 indicates that the fired ball sensor 14 is the game ball P.
When the ball is detected, the count value increases by one, and the return ball counter 19
When the return ball sensor 17 detects the return ball P', the count value increases by one.

The circuit shown in FIG. 6, which will be described later, generates a random number in response to a detection signal from the shot ball detection device 20, and when the random number matches a predetermined number, the variable prize winning device 3 forming a starting opening is activated.
L, 3C, and 3R are driven to convert into a second state advantageous to the player, and when a game ball wins a prize in any of them, the conversion drive is stopped and the variable winning devices 3L, 3C, and 3R are returned to the first state. .

If a predetermined number (for example, 1) of game balls do not win during these conversion drives, the next conversion drive will be a predetermined number of 2 game balls.
This is continued until twice (for example, two) game balls are won.

The conversion drive of the starting opening as described above may be either continuous or intermittent.Also, as a driving method for multiple variable winning devices, in addition to converting and driving all of them at once, each winning device may be driven once sequentially. There is a method of converting and driving each state into two states. According to this method, the winnings to be converted are circulated and it is interesting to display one, but when a predetermined number of game balls are won, the variable winning device that is driving the conversion stops. ! Compared to the case where all of the variable winning devices are stopped all at once, the change in all the variable winning devices is small and visually desirable.

Variable prize winning devices 3L, 3C and 3 forming the above-mentioned starting port
R is configured as shown in FIG. 4, for example.

First, there is a pair of movable pieces 42a on the front side of the game board.

42b is arranged so as to be openable and closable, and the lower part thereof is the cover member 4.
Covered by 3. This variable winning device has a pair of movable pieces 42
When a and 42b are closed as shown in FIG. 4 (IA), the game ball enters the first state in which the game ball cannot win a prize, and when opened as shown in FIG. 4 (Bl), the game ball becomes in the second state in which the game ball can win.

A bracket 45 housing 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 that come out from the upper and lower ends of the solenoid 44, respectively, and the disc 47 at the upper end and the bracket 4
A coil spring 49 is disposed between the upper surface of the coil spring 5 and the upper surface of the coil spring 5 . When the solenoid 44 is energized and energized, the lower end of the plunger 46 protrudes downward from the state shown in FIG. 4 (Al).

Thereafter, when the current is turned off and the solenoid 44 is demagnetized, the force of the coil blink 49 returns the plunger 46 to its original state. The variable winning device uses the movement of the plunger 46 to open and close a pair of movable pieces 42a and 42b.

The pair of movable pieces 42a and 42b each have a cylindrical base, and are rotatably supported inside the cover member 43 by an eccentric shaft 51 provided on the front side of each base. Each movable piece 4
A motion transmitting member 52 is provided between the bases of the solenoid 2a, 42b and the solenoid 44, which converts the vertical reciprocating motion of the plunger 46 into the opening/closing motion of the movable pieces 42a, 42b. This motion transmission member 52 is mainly composed of a rectangular plate, and a support portion 41a extends to the left and right rear of the mounting plate of the variable prize winning device, with protrusions 53a and 53b provided on the left and right end surfaces thereof as fulcrums.

41b so as to be rotatable. Furthermore, the motion transmission member 5
2 has an L-shaped protrusion 54 on the back side that extends over the disc 48 at the bottom of the solenoid, and a corresponding movable piece 42a on the front side.
, a pair of transmission rods 55a extending toward the base of 42b,
55b. The tip of each transmission rod 55a, 55b is formed thin and is slidably inserted into a hole 56a, 56b provided on the back side of the base of each movable piece 42a, 42b.

Between the bases of the pair of movable pieces 42a and 42b, a winning ball receiving part 58 is arranged, which has a triangular convex part 57 that receives a winning game ball and directs it backward when both rotating pieces are opened.
A gutter 59 for discharging winning balls is provided at the lower rear thereof. In addition to receiving winning balls, the winning ball receiving section 58 also receives a pair of movable pieces 4.
When the movable pieces 2a and 42b are opened, the pair of movable pieces 42a and 42b are held in the open state as shown in Fig. 4+131 by locking the convex pillars 60a and 60b that protrude downward from the base of each movable piece. It has the function of

In the variable winning devices 3L, 3G, and 3R configured as described above, when each solenoid 44 is not driven, the pair of movable pieces 42a and 42b are closed as shown in FIG. 4 (Al).

Here, when the solenoid 44 is energized and energized, the plunger 46 lowers against the spring 49 and pushes down the convex portion 54 of the motion transmission member 52 via the disk 48 at its lower end. Therefore, the motion transmission member 52 rotates and lifts the front side transmission rods 55a and 55b. As a result, Figure 4 (
As shown in b), the pair of movable pieces 42a and 42b open left and right, and each lower convex pillar 60a and 60b is connected to the winning ball receiving portion 5.

On the other hand, when the solenoid 44 is demagnetized by stopping the current supply, the plunger 46 is returned to its original state by the force of the coil spring 49. This upward movement of the plunger 46 causes the motion transmission member 52 to rotate in the opposite direction to the above, lowering the transmission rods 55a and 55b.

As a result, the pair of movable pieces 42a, 42b are in a closed state.

In this embodiment, the above-mentioned variable winning device is used as the starting hole for starting another game, but other winning devices may be used. By making a rod-shaped winning regulation member appear and disappear above,

Position where it is impossible or difficult to win (first state)
It is possible to use a device that is movable between the game ball and the position where the game ball can win (second state).

Next, the variable display device 4 for different games and the variable prize winning device 5 provided on the game board surface 2 will be explained.

As shown in FIG. 5, the variable display device 4 has a front part 32 mounted on the game board surface 2, and a pair of left and right small windows 33L and 33R are provided at the top of this front part 32, and a large window at the bottom. 34 are provided.

Inside the small windows 33L and 33R, there is a display 3 consisting of a 7-segment LED (light emitting diode) that variably displays numbers.
5L and 35R are arranged, and a part of the circumferential surface of the cylindrical reel 36 is exposed inside the large window 34. The reel 36 has its central axis placed horizontally as a fulcrum,
It is rotationally driven in one direction by a reel driving section 37 whose driving source is a pulse motor. On the circumferential surface of the reel 36, a plurality of (
For example, a sheet with 10 designs printed thereon is attached.

When the reel drive unit 37 stops rotating the reel 36,
The reel 36 is positioned so that one of the symbols on the sheet wound around its circumferential surface fits within the large window 34 of the front part 32. The above-mentioned indicators 35L, 35R and reel drive unit 37 include
A drive circuit 38 controlled by an output signal from the control section 25 shown in FIG. 6 is connected.

On the other hand, the variable winning device 5 is called an Atatsuka, and has a door of approximately the same shape attached to the front side of an opening provided at the top of a one-piece front plate so as to be openable and closable, and has a winning opening in the opening.

The door of this variable prize winning device 5 is opened and closed by a drive mechanism whose power source is a solenoid attached to the back side of the front plate.

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

As shown in FIG. 6, first random number generators 21 and 2 generate random numbers according to the output signals a and b from the launched ball counter 18 and the returned ball counter 19 that constitute the launched ball detection device 20 described above. A first determining unit 22 that determines the value of the generated random number, a second (7) random number generating unit 23 that generates another random number when the determined random number is a predetermined value, and a second (7) random number generating unit 23 that determines the value of the random number by γ
When the random number determined by the second determining section 24 and the first determining section 22 is a predetermined value, the variable display devices 3L, 3C
.

3R is driven to convert into the second state until a predetermined number of game balls win in any of them, and another game that is started when a prize is won in the starting opening is played according to the random number determined by the second determining section 24. A control unit 25 is provided to control the variable display device 4 so as to terminate the process in a result manner.

Further, a winning ball sensor 61 and a winning ball counter 62 are provided as winning ball detection means for detecting when a game ball enters any of the variable winning devices 3L, 3C, and 3R. The winning ball sensor 61 is composed of a magnetic sensor having a hole through which the game ball passes, and detects the winning ball from the change in the magnetic field when the game ball from each variable winning device passes through the hole. Of course, a sensor other than a magnetic sensor (such as an optical sensor or a microswitch) may be used. The detection signal of the winning ball sensor 61 is input manually to the winning ball counter 62, where the number of winning balls is counted. Furthermore, each variable winning device 3L, 3C, 3
A drive circuit 63 that drives the above-mentioned solenoid 44 for each R.
is provided.

The variable winning device (attacker) 5 is provided with an attacker winning ball sensor 7I and a winning ball counter 72 as means for detecting game balls that have won in the internal winning hole. The winning ball sensor 71 is composed of a magnetic sensor similar to the winning ball sensor 61 described above, and the detection signal of the 6 Atatsuka winning ball sensor 71 placed in the winning ball discharge path is input to the winning ball counter 72. The number of winning balls is counted here. Furthermore, solenoid 73 for Atatsuka's door drive
A drive circuit 74 is provided to drive the.

In the circuit shown in FIG. 6, the first random number generator 21 generates a random number by performing a predetermined calculation every time the shot ball counter 18 counts 1. However, the condition is that the value of the return ball counter 19 is 0, and if the counted value is 1 or more, no random number is generated.

For example, when the count of the return ball counter 19 is 2,
From the time of counting, the count output of the shot ball counter 18 is passed twice (no random number is generated). Then, count down the number of bone and return ball count 19 to 0.
Outputs signal C to make

If the value of the random number generated by this random number generator 21 hits a predetermined number, the starting port will be converted and driven to the second state advantageous to the player as described above, but the probability is as follows. stipulated in For example, λ, the range in which random numbers are generated is l~40
96, the range of random numbers to open the starting port is l~27
3, the probability of converting and driving the starting port to the second state is approximately 1/15.

The first determining unit 22 determines whether the value of the random number generated by the first random number generating unit 21 falls within the range t: determined as described above.

The control unit 25 controls the variable prize winning device 3L when the random number determined by the first I'll determination unit 22 is a value that opens the starting opening.

Drive No. 18 is sent to the drive circuit 63 that converts and drives the movable pieces 3C and 3R, and the solenoid 44 is driven so that these variable winning devices are in the second state.

During this conversion drive, when a game ball wins in any of the variable winning devices and the τ counter 62 outputs an output, the variable winning device is returned to the first state disadvantageous to the player and stopped.

Further, when the winning ball counter 62 reaches a predetermined value due to the game ball entering the starting hole (if the value is 1, the game 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, and converts the random number value into a second
The determination unit 24 makes the determination. As a result, when the value of the random number hits a predetermined number, the separate game is ended with a specific result pattern (for example, a jackpot), and the probability of the specific result pattern is determined as follows. For example, if the range in which random numbers are generated is 1 to 4096, and the range of random numbers that result in a jackpot is 1001 to 1012, the probability of a jackpot is approximately 1/341.

Thus, if the result of another game is a jackpot, the control unit 2
5 sends a signal to the drive circuit 38 to stop the variable display device 4 while displaying the jackpot, 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 or miss other than a jackpot (probability is determined by the range of random numbers set correspondingly)
, the separate gaming device 4 is stopped with a corresponding display,
If it is a hit, a predetermined number of prize balls will be paid out.

In the circuit of FIG. 6, the first and second random number generators 21.
23 and the first and second determination units 22.24 may be configured as a single random number generation means and a single determination means, respectively.
Also, the random number generator mentioned above.

The determination section and the control section can each be constructed from known electronic circuits, but these operations may be executed by a microcomputer.

In that case, a predetermined number of microcomputers (for example, 1
A random number is shaken every time a game ball (number of game balls) is fired, and when that value is a winning lottery, that is, when it is the value that opens the starting hole, a flag l is set. And variable prize winning devices 3L, 3C
, 3R intermittently or continuously into a second state advantageous to the player, and is programmed to stop the conversion drive when a game ball wins in any of the variable winning devices. When a flag 1 is set but there are no game balls, the flag generated in the next lottery is set to 2, and the variable prize winning device is driven to convert until the number of game balls including the carried over number is won. In addition, if, for example, two game balls are won in the starting slot when the flag l is set, the flag is set as one and is offset with the flag l generated in the next lottery.

On the other hand, if the value of the random number generated by the second random number generation section 23 hits the jackpot, a flag corresponding to the hit is set.

By the way, the variable prize winning devices 3L and 3C of the embodiment.

In 3R, the first state is a state in which the game ball cannot win by closing the pair of movable pieces, but in the first state of the variable winning device used in the present invention, it is difficult for the game ball to win (it is impossible to win). In that case, even if the variable prize device is in the first state, that is, when the above flag I is not set, the game ball is placed in the variable grand prize device. A grand prize may occur, and such a prize is detected by the winning ball sensor 61. At that time, the microcomputer sets the flag to -1 and offsets it with the flag 1 generated in the subsequent lottery.

By using the microcomputer and setting the flags as described above, it is possible to execute the state conversion of start [ ] and the result mode of another game with predetermined probabilities. Also, when the starting port is converted to the second state, when playing another game, or when the attack is open due to the result of another game, if the next flag is q, , it is possible to memorize it and execute an operation according to the state of the flag at any other necessary time after displaying the result of another game.

Although the embodiments have been described above, the present invention is not limited to pachinko gaming machines, but can be applied to smart pole machines, mahjong ball gaming machines, and other pinball gaming machines. Also.

The configuration and arrangement of the starting port are arbitrary, and any other variable display device of the embodiment can be used as a separate game device.

[Effects of the Invention] As described above, the pinball 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 every time a predetermined number of game balls are fired. At the same time, since the result pattern of the separate game started with the grand prize in the starting slot is also determined by random numbers, it is possible to adjust the probabilities of the state conversion of the start [] and the result pattern of the separate game, respectively. Therefore, players are given equal opportunities to win prizes in the starting slot and earn profits according to the results of other games, and can enjoy the pinball game regardless of the skill E (t) of the game. , it has the effect of being able to manage the player'1τ rate without the need for conventional nail adjustments6.
