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, a ball game machine provided with a variable winning device capable of converting a first state, which is disadvantageous to the player, and a second state, which is advantageous to the player, with respect to winning of a game ball (hit ball) hit on the surface of the game board. Regarding

[Prior Art] For example, in a pachinko gaming machine, the probability that a hit ball wins a winning opening changes depending on the position and direction of the nails arranged on the game board surface, the bending angle, the interval between the nails, and the like. For this reason, adjusting nails is an important task for pachinko parlors, and for players, finding a pachinko machine that is adjusted so that balls often come out is one of the conditions for winning more prize balls. There is.

However, adjusting the direction and spacing of the nails, which determines the winning rate of the hit ball, is a very delicate work performed in units of 0.01 mm, and requires an expert with skilled adjustment technology.

Therefore, the following device has been proposed as a device for adjusting the winning rate of a hit ball by automatically adjusting the nails of a pachinko machine.

The opening of a pair of nails provided above the winning opening is changed within a certain range (Japanese Patent Publication No. 59-356).
No. 33), the position or inclination of the nails provided in each winning portion is changed according to the winning rate of each winning opening (Japanese Patent Publication No. 61-
36949).

On the other hand, there is also known a technique of variably controlling the winning rate by setting the opening time of a variable winning device such as a tulip instead of adjusting the nail. For example, the opening time of the winning device is controlled so that the profit index of the pachinko parlor is set within a certain range (Japanese Patent Laid-Open No. 54-7).
No. 8233), the opening time of the variable winning device is specified based on a random number generated electronically (Japanese Patent Publication No. 61-4754).
No. 8).

[Problems to be Solved by the Invention] However, in the above-described device for adjusting nails, since it is required to perform delicate adjustments with high precision, the adjustment mechanism becomes precise and expensive, and the conventional mechanism It is practically difficult to adopt as an alternative to manual labor.
Furthermore, in conventional pachinko machines, the degree to which the hitting ball depends on the skill of the player is high, and it is difficult for a specific expert who is called a professional to put out the ball, so it is an equal game for the general public. There was also a problem that it lacked.

Further, even if the opening time of the variable winning device is set as described above, it is difficult to finely variably set the winning ratio as in the nail adjustment.

The present invention has been made in view of such problems,
It is an object of the present invention to provide a ball-and-ball game machine in which prize balls can be obtained with an equal probability regardless of the skill of a player and nail adjustment is not required.

[Means for Solving the Problem] The present invention relates to a variable winning device which can be converted into a first state, which is disadvantageous to the player, and a second state, which is advantageous to the player, with respect to winning of a game ball shot on a game board surface. In a ball game machine equipped with, the state of the variable winning a prize device is determined by the value of the randomly generated random number, a state display signal indicating the determined state is generated, and the variable winning a prize device according to the contents of the state display signal. Control means for controlling the state conversion of.

By the way, in an actual ball game, the determination (state display signal) based on a random number and the result (actual winning number) do not always match. For example, when the variable winning device is in the second state, the predetermined number of game balls are not always won, and the number may be less or more than the predetermined number. In addition, the variable winning device is the first state in which no game balls can be won.
There are a state and a state in which it is difficult but not impossible to win a prize. In the latter case, a game ball may win even if the variable winning device is in the first state. Therefore, the present invention is characterized in that the control means corrects the content of the state display signal according to the winning situation up to that point.

As one aspect of the present invention, the above-mentioned state display signal indicates the number of winning balls that can be accepted by the variable display device while the variable winning device is being converted to the second state, and until the next state display signal is generated. When the number of the game balls has not been won, the next state display signal is generated as a number indicating the number of deficiencies up to that point.

As another aspect, the status display signal indicates the second variable winning device.
Shows the number of winning balls that can be accepted by the variable display device while converting to the state, and if the number of gaming balls exceeding that number is won by the time the next state display signal occurs, the next state display signal will be , Will occur as a deduction of the excess amount up to that point.

According to still another aspect, when the state display signal indicates the first state, the control means, when the game ball is won in the variable winning device, performs the subsequent conversion to the second state for each winning. It is characterized in that a state display signal that cancels out is generated.

[Operation] In the ball game machine of the present invention, at an appropriate timing,
For example, every time a predetermined number of game balls are shot, the random number generating means generates a random number, and the determining means determines the value. According to the result, the control means generates the status display signal. The state display signal is called a flag when a CPU such as a microcomputer is used as the control means. For example, the number of winning balls to be received when the variable winning device is converted into the second state advantageous to the player ( The number of possible winnings) is shown.

More specifically, when the random number hits a value or range defined to set the variable winning device to the second state, the CPU generates a flag 1 (when the number of possible winnings is 1), and
The variable winning device in the first state is converted and driven to the second state. 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. Then, when a predetermined number of game balls are won in the variable winning device which is being converted and driven, the variable winning device is returned to the first state again.

According to one aspect of the present invention, when a flag indicating the number of possible wins is set and the number of game balls of the number of possible wins does not enter the variable winning device, the game is carried over to the next time. That is,
The content of the flag is added (for example, 1 to 2), and the conversion drive to the next second state is performed until the number of game balls including the carryover amount is won.

According to another aspect, when a flag indicating the number of possible winnings is set and more game balls than the number of winning possibles are won in the variable winning device, when converting to the second state next time,
Subtract the excess until then. That is, the content of the flag is subtracted (for example, from 1 to 0), and the next conversion drive to the second state is until the number of game balls (which may be 0) minus the excess is won.

According to still another aspect, when the state display signal indicates the first state (when the possible winning number is not flagged), when the game ball has won the variable winning device, The conversion to the second state is canceled each time. That is, the value of the flag is subtracted by -1.

Thus, by determining the conversion of the variable winning device to the second state with the probability of appearance of a predetermined random number value and correcting the state display signal according to the actual winning situation, the conversion driving of the variable winning device can be performed. It is controlled accurately. Therefore, the players are given equal opportunity to win the prize and a certain number of prize balls, and the winning rate can be managed in the game hall without the conventional nail adjustment.

[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,
Regarding the winning of the game balls shot from the launching device to be described later on the game board surface 2, a plurality of variable winning devices are arranged which are converted into a first state which is disadvantageous to the player and a second state which is advantageous to the player. . These variable winning devices are divided into two types, a general winning port and a specific winning port described later.

In addition, a large number of nails 3 are arranged as guide means for guiding the game ball hit on the game board surface 2 to the upper part of the variable winning device. On the other hand, a ball hitting handle 4 is provided on the lower right side of the front surface, and when the player operates it, a game ball is launched from a launching device attached to the back side of the game board, along a guide rail on the game board surface 2. It is designed to move.

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 61 described later.

The game ball P launched from the launch device passes through the launch ball passage 15 and rises along the guide rail 18 toward the game board surface, but returns to the launch device without reaching the game board surface 2. The ball P ′ falls on the recovery path 16. A return ball sensor 17 that detects this is arranged in the middle of the recovery path 16, and the output of the return ball sensor 17 is sent to a return ball counter 62 described later. 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.

In the present embodiment, a random number is generated in accordance with a detection signal from the launch ball sensor 14 as described later, and when the random number value reaches a predetermined number, a plurality of variable winning a prize devices are advantageous to the player. Conversion driving is intermittently or continuously performed in two states, and when a game ball is won in one of the variable winning apparatuses, the conversion driving is stopped and the variable winning apparatus is returned to the first state. In the meantime, when more or less than a predetermined number of game balls are won in the variable winning device, a status display signal (flag) for correcting the excess or the shortage is generated.

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
When the winning prize opening to be converted circulates and the display is interesting, when the predetermined number of game balls wins, the variable winning device in the conversion drive stops, so when all of the multiple variable winning devices stop at the same time. Compared with, the change of the entire variable winning device is small, which is visually desirable.

Here, the electric circuit portion of the embodiment will be described.

As shown in FIG. 3, a launch ball counter 61 and a return ball counter 62 which receive detection signals from the launch ball sensor 14 and the return ball sensor 17, respectively, and both counters 61,
A random number generator 63 that generates a random number according to the output of 62,
A determination unit 64 for determining the value of the generated random number, and a control unit 65 for performing conversion drive of the variable winning device until a game ball is won in any of the variable winning devices according to the determination result. To be

Further, as a winning ball detecting means for detecting a game ball when any of the variable winning devices 5L, 5C, 5R of the general winning opening and the variable winning devices 8L, 8R of the specific winning opening is detected, a general winning ball sensor 66 is provided. (3) and special winning ball sensor 67
(2 pieces) are provided. Each winning ball sensor 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 coming out of 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 each winning ball sensor is input to the corresponding winning ball counter 68 or 69, where the number of winning balls is counted.

In the circuit of FIG. 3, when the launch ball sensor 14 detects the game ball P, the launch ball counter 61 increases the count value by one,
In the return ball counter 62, the return ball sensor 17 returns the return ball P ′.
When is detected, the count value increases by one.

The random number generator 63 performs a predetermined calculation each time the firing ball counter 61 counts 1 to generate a random number. However,
On condition that the value of the return sphere counter 62 is 0, if the count value is 1 or more, no random number is generated. For example,
When the return sphere counter 62 is 2, the count output of the firing sphere counter 61 is passed twice (no random number is generated) from the time when it is counted. Then, the return sphere counter 62 is counted down by the number of times to 0. In addition,
The condition for generating the random number is not limited to the launch of the game ball.

When the value of the random number generated by the random number generating unit 63 reaches a predetermined number, the variable winning device of the type (general winning opening or specific winning opening) corresponding to that is converted into the second state advantageous to the player. The probability is determined in advance depending on the type of winning hole. For example, the range of random numbers is 1 to
In the case of 4096, if the range of the random number value corresponding to the general winning opening is 1 to 91, the probability of hitting the general winning opening is about 45.
If the range of the random number value corresponding to the specific winning opening (starting opening) is 1001 to 1273, the probability of hitting the specific winning opening is about 1/15.

The determination unit 64 determines whether the value of the random number generated by the random number generation unit 63 falls within the range defined as above.

As a result of the random number determination by the determination unit 64, the control unit 65, if the predetermined value is reached, the variable winning device 5L of the general winning opening,
A drive signal is sent to the drive unit 71 for converting and driving 5C and 5R or the drive unit 72 for converting and driving the variable winning device 8L and 8R of the specific winning opening, and a predetermined number of the variable winning devices are intermittently or continuously second. Drive to reach the state. During this conversion drive, the game ball wins the variable winning device and the counter 6
When 8 or 69 is output, the variable winning device is returned to the first state, which is disadvantageous to the player, and stopped.

Further, as shown in FIG. 1, in the case of a ball game machine provided with the variable display device 7 and the variable winning device 20 for performing another game, the specific winning ball counter 69 is predetermined when the game ball wins the starting opening. When the value is reached (when the value is 1, the game ball wins), the control unit 65 causes the variable display device 7 for another game.
To send a signal to the drive unit to start another game. at the same time,
A random number is generated in the random number generation unit 63, and the random number value is determined by the determination unit 64. Then, according to the determination result, when the result mode of another game is a big hit (the probability is predetermined as in the case of the variable winning device), the display of the variable display device 7 is stopped at the big hit and the variable winning device 20 It outputs a signal that opens the door for a certain period of time (in a state advantageous to the player). In addition, in the case of a hit other than the big hit or in the case of a miss, the display of the variable display device 7 is stopped correspondingly, and in the case of a hit, a predetermined number of prize balls are paid out. This point is similar to the conventional ball game machine.

The variable display device 7 has a pair of left and right small windows in the upper part of the front part mounted on the game board surface 2 and a large window in the lower part. 7-segment LE for displaying numbers variably in the small window
An indicator composed of D (light emitting diode) is arranged, and is arranged so that a part of the peripheral surface of the cylindrical reel appears in the large window. The reel is rotationally driven in one direction by a reel driving unit having a pulse motor as a driving source, with a central axis placed horizontally as a fulcrum. A sheet on which a plurality of (for example, 10) symbols are printed is mounted on the peripheral surface of the reel. The reel drive unit positions the reel so that, when the rotation of the reel is stopped, one of the symbols of the sheet wound on the peripheral surface is accommodated in the large window in the front.

On the other hand, the variable winning a prize mounting 20 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 20 is opened and closed by a drive mechanism having a solenoid as a power source attached to the back side of the front plate.

The launch ball counter 61, the return ball counter 62, the random number generator 63, the determination unit 64, the controller 65, and the winning ball counters 66 and 67 can be configured by known electronic circuits, respectively. It is better to configure with a computer.

In that case, the microcomputer throws a random number each time a predetermined number of game balls are shot, and when the value hits the lottery, that is, when it enters the range corresponding to the general winning opening or the specific winning opening, a flag. Set 1. The flag of this embodiment is
It is a state display signal indicating the number of winning balls (possible winning number) to be accepted when the variable winning device is set in the second state advantageous to the player. The microcomputer outputs a signal for intermittently or continuously converting and driving the variable winning award devices 5L, 5C and 5R of the general winning a prize corresponding to a predetermined flag or the variable award winning devices 8L, 8R of the specific award winning prize to the second state. It outputs and is programmed to stop the conversion drive when a game ball enters any of the variable winning devices that are driving the conversion.

If the game ball does not win even if the above 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 two game balls are won. After that,
If there is no winning ball, the content of the flag increases by 1 each time it occurs.

Also, when the flag 1 is standing, there are n game balls (n ≧
2) If you have won the prize, change the content of the flag to (1-
As n), the flag 1 generated in the next lottery is offset.
For example, when n = 3, the next flag is -2,
After that, each time a flag is generated, it becomes -1,0.

By the way, the first state of the variable winning device used in the present invention is not limited to the state in which the game ball cannot be won, but may be the state in which the game ball is difficult to win (the winning is difficult but 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. Since such a winning is detected by the winning ball sensor 66 or 67, the microcomputer subtracts -1 from the flag corresponding to the general winning opening or the specific winning opening for each winning of the game ball, and is generated in the subsequent lottery. Offset with flag 1.

As described above, by using the microcomputer, the flag indicating the number of times the variable winning device is converted to the second state is corrected in accordance with the actual winning situation, so that the state of the variable winning device is changed with a predetermined probability. You can

The winning rate of the game balls with respect to the above variable winning device can be arbitrarily set by changing the probability that a random number value for converting the variable winning device into the second state appears. The probability of the result mode of another game can be similarly set.

Next, in the embodiment shown in FIG. 1, the variable winning device (the winning regulation system by the moving member) shown in FIG. 4 is used as a general winning opening, and the variable winning shown in FIG. 6 is used as a specific winning opening, that is, a starting opening for another game. The device (opening and closing type) is used. On the contrary, both may be replaced and used.

The general winning opening is a predetermined number (eg 1
(3 pieces) prize balls are paid out, and in the embodiment of FIG. 1, the game balls cannot be won (or are difficult to win) due to the movement of the prize regulating member located above the prize opening. It is composed of a variable winning device that is converted into a second state in which a prize can be won, and is arranged on the left and right and the center of the game board surface 2.

Fit and connect the rear ends of. The male screw portion 24 is coupled to the shaft of the pulse motor 27. Therefore, when the pulse motor 27 is driven by an appropriate control device to rotate the male screw portion 24, the female screw portion 25
Moves along the male screw portion 24, and the prize-winning restriction member 6 appears and disappears perpendicularly to the game board surface 2. At this time, the amount of movement of the winning restriction member 6 is determined by the rotation angle of the male screw portion 24, and the rotation angle is determined by the number of pulses for driving the pulse motor 27. Therefore, by controlling the number of drive pulses supplied to the pulse motor 27, the position of the winning restriction member 6 protruding from the game board surface 2 is adjusted, and the game ball P can win the first state in which the game ball P cannot win the opening 21. It can be converted into two states.
