Description

Description: TECHNICAL FIELD The present invention relates to a ball game machine such as a pachinko machine, and more specifically, a game ball (launch ball) launched from a launcher onto a game board surface. The present invention relates to a ball-and-ball game machine which detects and controls according to the number.

[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 devices have been proposed as devices for automatically adjusting the nails of a pachinko machine to adjust the winning rate of a hit ball.

The opening of a pair of nails provided above the winning opening is changed within a certain range (Japanese Patent Publication No. 59-35633).
No.), 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. 61-36).
No. 949).

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 a pachinko parlor is set within a certain range (Japanese Patent Laid-Open No. 54-7823).
No. 3), in which the opening time of the variable winning device is designated based on an electronically generated random number (JP-A-61-47548).
issue).

[Problems to be Solved by the Invention] However, in the device for adjusting the nails described above and the above, since it is required to perform delicate adjustments with good precision, the adjustment mechanism becomes precise and expensive, and the conventional mechanism It is practically difficult to adopt as an alternative to manual labor.

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.

Furthermore, in the conventional pachinko machine that is finely adjusted as described above, the degree of hitting ball winning depends on the skill of the player, and it is difficult for the player to put out the ball unless the player is a specific expert. There is also a problem that it lacks equality as a game for the general public.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a ball-and-ball game machine that can obtain prize balls with equal probability and does not require nail adjustment, regardless of the skill of the player. To do.

[Means for Solving the Problem] The present invention relates to a ball-ball game machine which shoots a game ball from a launching device toward a game board surface in response to a player's operation, and a predetermined number of game balls are launched from the launching device. And a control means for generating a random number in response to an output signal from the fired ball detection means and performing a winning control of a ball game according to the value of the random number. Characterize.

In the present invention, a return ball detecting means for detecting a game ball returning without being reached on the game board surface after being launched from the launching device is provided, and the control means does not generate random numbers for the number of return balls detected. Is preferred.

[Operation] In the ball game machine of the present invention, the launch ball detection means outputs each time a predetermined number (for example, one) of game balls are launched from the launch device. The control means generates a random number according to the output signal, and performs the winning control of the ball game according to the value of the random number.

As an example of prize control, in a ball game machine having a variable winning device that can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player with respect to winning of a game ball shot from the launching device, When the random number value is a predetermined value, the variable winning device is converted and driven to the second state which 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. Then, when a predetermined number of game balls are won in the variable winning device that is being converted and driven, the variable winning device is stopped in the first state.

As another example, in a ball game machine equipped with another game device that starts another game when a launch ball enters a specific winning opening called a start opening, when the random number value is a predetermined value, the other game is specified. The other game device is controlled so as to end in the result mode.

As described above, the present invention performs winning control such as state conversion of the variable winning device and determination of the result mode of another game based on the detection of the shooting ball, and the winning rate is preset for a predetermined number of shooting balls. Since it is determined by the probability that the defined random number will appear,
While the players are equally given the opportunity to win a prize in the winning device or obtain prize balls by another game, the winning rate can be managed in the game hall without the conventional nail adjustment.

According to a preferred aspect of the present invention, the return ball is excluded and a random number is generated based on the game ball that actually reaches the game board surface, so that more accurate winning control is performed.

[Embodiment] FIG. 1 is a front view of a pachinko gaming machine which is an embodiment of the present invention. The gaming board surface 2 of the pachinko gaming machine 1 is converted into a first state that is unfavorable to the player and a second state that is advantageous to the player with respect to winning of a game ball that is launched onto the gaming board surface 2 from a launching device described later. A plurality of variable winning devices are arranged. These variable winning devices are classified into two types, a general winning port and a specific winning port (referred to as a starting port).

The general winning opening is for paying out a predetermined number (for example, 13) of prize balls when a game ball enters it. In this embodiment,
A variable that is converted into a first state in which the game ball cannot be won (or is difficult to win) and a second state in which the game ball can be won (or is easy to win) due to the movement of the prize restriction member located above the prize hole It is composed of a prize winning device, and variable prize winning devices 5L, 5R, 5C are arranged on the left, right and center of the game board surface 2.

The variable winning devices 5L, 5R, 5C are U-shaped ball receiving members that receive the game balls one by one in a bowl-shaped opening facing the game board surface 2 and send them out to the back side of the game board surface 2, and above it. And a winning restriction member formed of a rod-shaped moving member penetrating the game board surface 2 and projecting to the front side. The winning restriction member is driven perpendicularly to the game board surface 2 by a driving unit 71 (FIG. 4) including a motion converting means for converting the rotation of the pulse motor into a reciprocating motion. In this case, the amount of movement of the winning restriction member is determined by the rotation angle of the pulse motor, and the rotation angle is determined by the number of pulses driving the pulse motor. Therefore, by controlling the number of drive pulses supplied to the pulse motor, the position of the winning restriction member protruding from the game board surface 2 is adjusted, and the game ball is converted into the first state in which the game ball cannot win and the second state in which the game ball can win. You can In addition, it is preferable that the entire surface of the variable winning device is covered with a decorative plate so that the winning restriction member cannot be seen.

On the other hand, the specific winning opening is a starting opening for paying out a predetermined number (eg, 7) of prize balls when a game ball enters it and for starting another game by the variable display device 7 arranged in the central portion of the game board surface 2. Yes, in this embodiment, the game ball cannot be won (or is difficult to win) by closing the pair of movable pieces.
It becomes a state, and consists of a variable winning device (so-called tulip) which is converted into a second state in which a game ball can be won (or easy to win) by opening a pair of movable pieces, and a variable winning device 8L on the left and right of the game board surface 2 And 8R are arranged. A pair of movable pieces of each variable winning device 8L, 8R is opened by energizing the solenoid to energize the drive unit 72 (Fig. 4) including a solenoid arranged on the back side of the game board, and deenergize the solenoid. It is configured to close when degaussed. In addition to the variable winning device as described above, a normal winning port (chucker) or a passage type winning port may be used as the starting port for starting another game.

In contrast to the above, an openable-type variable winning device (tulip) may be used as the general winning port, and a movable variable winning device may be used as the specific winning port.

In order to detect the game balls that have won the general and specific winning openings as described above, prize ball sensors 66 and 67 (FIG. 4) that magnetically detect the passage of the game balls are used. The outputs of these sensors are sent to the control means described later via a counter described later.

Similar to the conventional pachinko game machine, a large number of nails 3 are arranged as a guide means for guiding the game ball hit on the game board surface 2 to the upper part of the variable winning device, while the ball hitting handle 4 is provided on the lower right side of the front face. Is provided, and when the player operates it, a game ball is launched from a launching device mounted on the back side of the game board and moves along a guide rail on the game board surface 2.

Further, in the center of the game board surface 2, a variable display device 7 for performing another game is arranged, and below the variable prize device 20 having a door that opens when the result of another game is in a specific display mode. Is provided. As a mode of another game, in addition to variable display by the variable display device 7, conversion driving of a variable winning device may be used.

As the game ball launching device, for example, the one shown in FIG. 2 is used. The launching device 9 is composed of a hitting ball launching portion 11 including a solenoid for projecting the game ball P by projecting the plunger 10 by an electromagnetic force, and a hitting ball guiding portion 12 provided on the plunger projecting side. The hit ball guiding unit 12 is a game ball P.
It is formed of a cylindrical member with a tip portion cut out for sending in, and a pair of parallel ridges 13 for guiding the game ball P flipped by the tip of the plunger 10 forward are provided on the inner bottom surface thereof. .

Furthermore, since each time a game ball P is launched from the launch device 9, it is detected, a launch ball sensor is provided in front of the launch device 9.
14 are placed. The launch ball sensor 14 comprises 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 (FIG. 4) described later.

The game ball P launched from the launching device 9 passes through the launch ball passage 15 and rises along the guide rail toward the game board surface 2 as shown in FIG. 3, but is launched without reaching the game board surface 2. The return ball P ′ returning to the device 9 is the recovery path 16
To fall. In order to detect this, a return ball sensor 17 is arranged in the middle of the collection path 16. The output of the return ball sensor 17 is sent to a return ball counter 62 (FIG. 4) described later. As a result, the game ball (return ball) that has returned to the launching device 9 without reaching the game board surface 2 is not counted as a launch ball.

In this embodiment, a random number is generated according to a detection signal from the firing ball sensor 14 as described later, and winning control is performed according to the random number value. That is, when the generated random number reaches a predetermined number, the plurality of variable winning devices are conversion-driven in a specific manner (for example, all or a plurality of variable winning devices are converted into a second state advantageous to the player). Then, when the game ball wins any of the variable winning devices that are being converted and driven, the conversion driving of all variable winning devices is stopped and the variable winning devices are returned to the first state. If the game ball does not win the variable winning device,
Conversion drive is performed until a predetermined number of game balls (two, for example) are won.

As a method of driving a 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 sequentially converting and driving each winning apparatus into two states once. According to the latter method, the winning opening for conversion is circulated, and while the display is interesting, the variable winning device that is being driven for conversion is stopped when a predetermined number of game balls are won. Compared with the case where all of them are stopped at the same time, the change of all the variable winning devices is small, which is visually desirable.

As another example of winning control, another game started by winning a game ball in one of the starting openings is ended in a specific progress mode. For example, the variable display of the variable display device 7 is stopped in a mode in which the same number "7" is displayed in the three display windows, and the door of the variable winning device 20 is opened for a certain period of time so that a relatively large number of prize balls can be displayed to the player. Will be given.

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. A display consisting of a 7-segment LED (light emitting diode) that variably displays numbers is placed in a pair of small windows.
In the large window, a part of the peripheral surface of the cylindrical reel is arranged to appear. The reel is rotatably driven in one direction by a reel driving section using a pulse motor as a driving source, with a central axis of the reel placed horizontally as a fulcrum. On the surface of the reel,
A sheet on which a plurality of (for example, 10) patterns are printed is attached. 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 of the reel drive unit is accommodated in the large window in the front portion.

The variable winning device 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 an opening provided in the upper part of a 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.

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

As shown in FIG. 4, 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 a random number according to outputs a and b of both counters 61 and 62. A random number generation unit 63 for generating, a determination unit 64 for determining the value of the generated random number, and conversion drive of the variable winning device until a game ball is won in any one of the plurality of variable winning devices according to the determination result. And a control unit 65 for performing the operation.

Also, as a winning ball detection means for detecting the game ball when any of the variable winning device 5L, 5C, 5R of the general winning opening and the variable winning device 8L, 8R of the specific winning opening is detected, the general winning ball sensor 66 (3) and specific winning ball sensors 67 (2) 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,
Here, the number of winning balls is counted.

In the circuit of FIG. 4, the launch ball counter 61 increments by one when the launch ball sensor 14 detects the game ball P, and the return ball counter 62 counts when the return ball sensor 17 detects the return ball P '. The number increases by one.

The random number generator 63 performs a predetermined calculation every time the firing ball counter 61 counts 1 to generate a random number. However, if the value of the return sphere counter 62 is 0, and the count value is 1 or more, a random number is not generated. For example, when the return ball counter 62 is 2, a signal that passes the count output of the launch ball counter 61 twice (does not generate a random number) from the time when it counts, and counts down the return ball counter 62 to 0. Output c.

When the value of the random number generated by the random number generator 63 reaches a predetermined number, a variable winning device of a type (general winning opening or specific winning opening) corresponding to that is converted into a second state advantageous to the player. However, the probability is predetermined depending on the type of winning hole. For example, the range of random numbers is 1-40
When set to 96, the range of the random number value corresponding to the general winning a prize is 1
If it is ~ 91, the probability of hitting the general winning opening is about 1/45, and the range of the random number value corresponding to the specific winning opening (starting opening) is 10
If it is 01 to 1273, the probability of hitting a specific winning opening is about 1/15
Becomes

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 hit, the variable winning device 5L, 5C, 5R of the general winning opening.
Drive unit 71 for converting and driving a variable winning device with a specific winning opening
A drive signal is sent to the drive unit 72 that converts and drives 8L and 8R, and a predetermined number of variable winning apparatuses are intermittently or continuously provided in the second.
Drive to reach the state. During this conversion driving, when the game ball is won in the variable winning device and the counter 68 or 69 outputs, the variable winning device is returned to the first state, which is disadvantageous to the player, and stopped.

Further, in the case of a ball game machine equipped with a variable display device 7 for another game and a variable winning device 20 as in the embodiment of FIG. 1, a specific winning ball counter is obtained by winning the game ball at the starting opening.
When 69 reaches a predetermined value (if the value is 1, the game ball wins), the control unit 65 sends a signal to the drive unit of the variable display device 7 to start another game. At the same time, the random number generator 63 generates a random number, and the determination unit 64 determines the random number value. 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 separate game device 7 is stopped correspondingly, and in the case of a hit, a predetermined number of prize balls are paid out.

The launch ball counter 61, the return ball counter 62, the random number generation unit 63, the determination unit 64, the control unit 65, and the winning ball counters 68 and 69.
Can be configured by known electronic circuits, respectively, but a microcomputer may perform these operations.

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. Then, the variable winning a prize winning device of the general winning a prize mouth or the specific winning a prize corresponding to the flag is output a signal for intermittently or continuously converting and driving the variable winning a prize device to the second state which is advantageous to the player, and the variable winning a prize device driving the conversion. Is programmed to stop the conversion drive when a game ball enters any of the. 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 two game balls are won. Also, when the flag 1 is standing, the game ball is 2
When the individual wins, the flag is set to -1 to offset the flag 1 generated in the next lottery.

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. Detected at 66 or 67. At that time, the microcomputer sets the flag corresponding to the winning general winning opening or the specific winning opening to -1, and offsets 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 variable winning a prize device can be executed with a predetermined probability.

The winning rate of the game balls with respect to the 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.

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 configuration of the launch ball detection means and the control means and the specific mode of winning control can be arbitrarily determined.

[Effects of the Invention] As described above, since the ball game machine of the present invention performs the winning control according to a predetermined probability every time a predetermined number of game balls are shot, the winning rate of the game balls is increased. It can be adjusted to a constant value. As a result, the conventional fine adjustment of nails is not necessary, and the player is given an equal opportunity to win the prize, and the player can enjoy the ball game regardless of the skill of the player.
