Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ball game machine such as a pachinko machine,
Specifically, the present invention relates to a ball game machine capable of controlling the winning rate of a game ball (hit ball) hit on a game board surface.

[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 changing the winning rate of a hit ball by automatically adjusting the nail 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. 59-35633).
No.), the position or inclination of the nails provided in each winning portion is changed according to the winning rate of each winning hole (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), the opening time of the variable winning device is specified based on a random number generated electronically (Japanese Patent Publication No. 61-47548).
issue).

[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 There is a problem that it is difficult to adopt it as a substitute for human labor.

On the other hand, in the above pachinko gaming machines, since the prize winning device, such as tulip, in which the morphological change can be seen is opened and closed, the technical intervention by the player is further increased, and the winning rate according to the opening time set by the machine is increased. Is difficult to achieve. There is also a problem that the winning rate for an arbitrary winning port cannot be finely and variably controlled by simply opening and closing the winning device, as in the case of nail adjustment.

The present invention has been made in view of such problems,
An object of the present invention is to provide a ball game machine capable of finely controlling the winning rate of a hit ball with respect to one or more winning holes without adjusting the nails and without impairing the game property.

[Means for Solving the Problem] The ball game machine of the present invention is movable in at least two directions between a position for accepting a game ball that has been hit on the game board surface and has reached the winning possible area, and a position for not accepting it. And a driving means for driving the moving winning opening in two directions on the game board surface, and the moving means moves the moving winning opening to a position represented by two-dimensional coordinates on the playing board surface. It comprises the movement control means for controlling as described above, and the position detection means for detecting the position of the movement winning opening and sending it to the movement control means.

In a specific aspect of the present invention, the mobile winning opening is
It is formed by a ball receiving member that receives game balls one by one in an opening that can move vertically and horizontally in two directions on the game board surface and sends them out to the back side of the game board surface, and the driving means can move the ball receiving member in the left and right directions. And a ball screw rotatably supported in the vertical direction, a first motor for driving the ball receiving member in the horizontal direction via the ball screw, and the ball receiving member swinging in the vertical direction using the ball screw as a fulcrum. The crank shaft is engaged with the ball receiving member so as to cause the ball receiving member to swing through the crank shaft.

[Operation] In the ball game machine of the present invention, the winning rate, that is, the probability that the hit ball enters the moving winning opening is determined by the position of the moving winning opening. The movable winning opening is movable in at least two directions with respect to the winning possible area on the game board surface, and the movement control means outputs a movement control signal for moving the moving winning opening to a position represented by two-dimensional coordinates, and drives it. The means drives the moving winning opening so that the means takes a position corresponding to this control signal. At that time, the position of the moving winning opening is detected by the position detecting means and input to the movement control means.

By the above operation, the moving winning opening is accurately positioned,
The winning rate can also be finely controlled.

[Examples] Hereinafter, description will be given with reference to the accompanying drawings.

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,
An appropriate number of movable winning openings 5 are provided together with the winning openings 3 and 4 whose positions are fixed. The mobile winning opening 5 of the embodiment will be described in detail later. Above each transfer winning port 5,
A passing ball detector 6 to be described later is arranged. In addition, a large number of nails 7 are arranged as hitting ball guiding means for guiding the pachinko balls hit on the game board surface 2 to the prize winning areas formed on the respective winning openings. A ball hitting handle 8 is provided on the lower right side of the front part, and by the player operating this,
A pachinko ball is launched between the guide rails of the game board surface 2 via the ball launching device on the back side.

Next, as shown in FIG. 2 and FIG.
Is formed by a ball receiving member 22 having a U-shaped cross section, which receives the pachinko balls P one by one in a bowl-shaped opening 21 facing the game board surface 2 and sends the pachinko balls P to the back side of the game board surface 2.

The ball receiving member 22 penetrates a through hole 2a provided in the game board surface 2 and is attached to the back side of the game board surface 2 in a U-shaped bracket 23.
It is movably supported to the left and right by a ball screw provided inside. That is, the male screw portion 24 of the ball screw is
The ball receiving member 22 is rotatably supported on both side walls of the bracket 23 by penetrating a female screw portion 25 arranged inside, and one end of the male screw portion 24 is connected to a shaft of a motor 26, and a disc 27 is connected to the other end. It is fixed. The disc 27 has a large number of small holes 28 formed at regular intervals along the periphery thereof. Position detectors 29 are provided on both sides of the peripheral edge of the disk 27, each of which includes a light sensor and a light sensor. Further, a spring for preventing play of the ball receiving member 22 is provided at a portion of the male screw portion 24 located between the ball receiving member 22 and one side wall of the bracket 23.
30 is wound.

Therefore, when the motor 26 is driven to rotate the male screw portion 24, the ball receiving member 22 moves left and right along with the female screw portion 25 along the male screw portion 24. At this time, from the output of the position detector 29, which changes when the small hole 28 of the disc 27 that rotates integrally with the male screw portion 24 passes between the light emitting element and the light receiving element, the rotation angle of the male screw portion 24, and thus the ball The position of the receiving member 22 is detected.

The opening 21 of the ball receiving member 22 can be moved in the vertical direction (vertical direction) in addition to the left-right direction (lateral direction). As a mechanism therefor, a crankshaft 31 having a bent middle portion is provided at the rear of the ball screw, and the middle portion of the shaft penetrates through long holes 32 formed in both side walls of the ball receiving member 22. This crankshaft 31
Both ends of are rotatably supported on both side walls of the bracket 23,
One end of the shaft 31 is connected to the shaft of the pulse motor 33.

Therefore, when the pulse motor 33 is driven to rotate the crankshaft 31, the ball receiving member 22 swings around the male screw portion 24 of the ball screw as a fulcrum, and the opening 21 moves up and down. In this case, the inclination of the ball receiving member 22 is determined by the rotation angle of the crank shaft 31, and the rotation angle is determined by the number of pulses driving the pulse motor 33. Therefore, by controlling the number of drive pulses supplied to the pulse motor 33, the inclination of the ball receiving member 22 can be adjusted to determine the vertical position of the opening 21.

The ball receiving member 22 is provided with round bars 34 on both sides of the opening 21 as a guide when the pachinko ball P enters the opening 21. In addition, the pachinko ball P that has entered the opening 21 is the game board surface 2
In order to guide you to the back side of and introduce it into the winning ball passage below,
The ball receiving member 22 has a winning ball passage hole 35 in the bottom surface portion located on the back side of the game board surface 2, and a partition wall 36 behind the passage hole 35.
Is equipped with.

Further, as shown in FIG. 3, a ball receiving member on the game board surface 2
The passing ball detector 6 arranged above 22 has a circular through hole 6a.
And a passing sphere is detected from the change of the magnetic field when the pachinko ball P passes through the through hole 6a. Of course, other detectors (optical sensor, micro switch, etc.) may be used. The passing ball detector 6 is attached through a hole provided in the game board surface 2.

On the back side of the game board surface 2, a winning ball detector 37 composed of the same sensor as the passing ball detector 6 is arranged below the bracket 23. The detector 37 detects a pachinko ball (winning ball) P that has entered the ball receiving member 22, and therefore passes the winning ball dropped from the winning ball passing hole 35 of the ball receiving member 22 through the bottom opening of the bracket 23. The through hole 37a is provided.

The opening of the ball receiving member that constitutes the moving winning port 5 as described above
21 is driven in two directions in the vertical and horizontal directions on the game board surface 2 by the driving means including the motors 26 and 33, the ball screw including the male screw portion 24 and the female screw portion 25, and the crankshaft 31. , 33 and the position detector 29 are connected to the movement control means described below. In the embodiment, the horizontal position of the ball receiving member 22 is detected from the output of the position detector 29, and the vertical position of the ball receiving member 22 is detected from the number of pulses for driving the pulse motor 33. This constitutes the position detecting means for detecting the position of the ball receiving member which is the moving winning opening and sending it to the movement controlling means.

The movement control means of the embodiment moves the moving winning opening 5 in two directions on the game board surface 2 so that the winning rate becomes a value set by an external device or a predetermined value. It is constructed as shown in FIG. 4 or FIG.

The movement control means 40 of FIG. 4 receives the detection signals from the passing ball detector 6 and the winning ball detector 37, respectively, and counts the number of passing balls and winning balls. A comparison calculation unit 43 that outputs a value obtained by performing a predetermined comparison calculation, and a determination unit that determines whether the output value is the set value input from the external setting device 44
45, and a control signal output unit 46 that generates a signal for controlling the drive of the above-described motors 26 and 33 based on the determination result. Drive circuits 47 and 48 connected to the motors 26 and 33 drive the motors according to the control signals output from the movement control means 40.

The setting device 44 is a means for setting and holding the winning rate of a pachinko ball at a desired value for each moving winning opening controlled by the movement control means 40, and its configuration is a plurality of numbers and the like for inputting. It may be any one that includes a key input unit and a storage unit that stores the input data. The value set by this device can be changed appropriately.

The comparison calculation in the control means 40 is performed as follows, for example. That is, the ratio of the number of winning balls to the number of passing balls (winning rate) is calculated from the outputs of the counters 41 and 42, and the moving winning opening is controlled so that the value becomes the value set by the setting device 44. In this way, the winning rate of each mobile winning port 5
For example, if it is set to 80%, this winning rate can be achieved for the entire moving winning opening. It is also possible to set different winning rates for each of the moving winning openings 5 so that the winning rate is within a certain range as a whole.

As shown in FIG. 6, for example, as shown in FIG. 6, the position at which each of the moving winning a prize mouths 5 is moved is, when a certain reference position E is the origin of xy coordinates,
It is assumed that there are nine points A to I whose values on the x-axis and the y-axis are either -1, 0, or +1. Different winning rates can be set corresponding to these positions. Further, these positions are not limited to equal intervals and can be set arbitrarily.

The movement control means as described above can be realized by a microcomputer. The microcomputer controls each part of the pachinko gaming machine, while controlling the movement of the moving winning port 5, so that the winning rate set by the setting device 44 is stored and the passing ball detector 6 and the winning ball detector are stored. The number of passing balls, winning balls, and other data obtained from the output of 37 are stored in a storage device (not shown) at any time.

Next, the movement control means 50 of FIG. 5 determines a random number generator 51 that electronically generates a random number, a sampling unit 52 that samples the generated random number at a certain timing, and when a certain condition is achieved. Mobile prize hole 5 corresponding to the random number
And a control signal output unit 54 that outputs a signal for controlling the driving of the motors 26 and 33 based on the determination result. It is assumed that the random number value is determined, for example, every time 500 game balls are hit by operating the hit ball handle 8 in FIG. 1, or at a fixed timing, and when other arbitrarily determined conditions are achieved. Movement control means 50
The motor drive circuits 47 and 48 drive the respective motors 26 and 33 in accordance with the signal output from the same as in the case of FIG. Such movement control means can also be realized by a microcomputer.

In this movement control means 50, the range of random numbers generated by the random number generator 51 is set to, for example, 1 to 4096 as shown in FIG. 7, and this is divided into ranges corresponding to the nine positions A to I in FIG. To do.
Then, the determining unit 53 determines the range to which the random number value determined as described above belongs. For example, when the random number hits between 23 and 30, the moving winning opening 5 is driven so as to come to the position I in FIG. In this case, the frame of the random number determined by the determination unit 53, that is, the classification of random number values as shown in FIG. 7, can be changed as appropriate by input from the external setting device.

Thus, according to the embodiment, the moving winning opening is precisely moved and controlled in the two vertical and horizontal directions represented by the two orthogonal axes to take a position corresponding to the arbitrarily set winning rate. At that time, the position of the moving winning opening is detected by the position detecting means. This makes it possible to comprehensively manage the winning rate and eliminates the conventional nail adjustment. In addition, the moving range of the moving prize hole can be set arbitrarily between a position that accepts a pachinko ball and a position that does not accept it, and it is sufficient if there is a distance that allows one pachinko ball to pass. The player's movement is not conspicuous, and the technical intervention of the player is not increased.

Although the present invention has been described above with reference to the embodiments, 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. In addition, the moving direction of the moving winning opening is not limited to the vertical and horizontal directions, that is, the two horizontal and vertical directions,
It may be diagonal. Further, the shape of the moving winning opening, the configuration of the control means and the driving means, and the like can be arbitrarily designed in addition to the illustrated example.

[Effects of the Invention] Since the ball game machine of the present invention is configured as described above, it is possible to finely control the winning rate of the hit ball for each winning opening by moving and adjusting the position of the moving winning opening. As a result, it is possible to eliminate the need for the conventional delicate nail adjustment and reduce the excessive technical intervention by the player called a professional.
