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. Therefore, 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 many prize balls. .

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] In the ball game machine of the first invention, the winning opening provided on the game board surface and the game ball hit on the playing board surface to reach above the winning opening are A prize restricting member movably installed between a position that prevents entry into the prize opening and a position that does not prevent it from entering the prize opening, drive means for moving the prize restricting member on the game board surface, and passing above the prize opening. Passing ball detecting means for detecting a game ball, winning ball detecting means for detecting a game ball winning the winning opening, the number of gaming balls detected by the passing ball detecting means and the winning ball detecting means And a movement control means for controlling the movement of the winning restriction member by the driving means so that the winning rate is calculated from the number of game balls and the calculated value becomes a preset winning rate value. .

A ball game machine of a second invention is a winning opening provided on a game board surface, and a position for preventing a game ball that has been hit on the game board surface and has reached above the winning opening from entering the winning opening. And a winning restriction member that is movably installed between a non-blocking position, a driving unit that moves the winning restriction member on the game board surface, a random number is generated, and determined when a certain condition is achieved during the game. And a movement control means for controlling the movement of the winning restriction member by the driving means based on the value of the random number.

According to a preferred aspect of the present invention, the winning restriction member is formed of a rod-shaped member that can project from the back side of the game board surface to above the winning opening, and the drive means moves the rod-shaped member in a direction perpendicular to the game board surface. It is configured with screws.

[Operation] In the ball game machine of the present invention, the winning rate, that is, the probability that the hit ball enters the winning opening is determined by the position of the winning restriction member.

According to the first aspect of the invention, the movement control means calculates the winning rate from the number of game balls detected by the passing ball detection means and the number of game balls detected by the winning ball detection means, and the calculated value is calculated in advance. It outputs a movement control signal for moving the prize limiting member on the game board surface so that the value of the set winning rate is achieved.

According to the second aspect of the invention, the movement control means generates a random number, and moves the winning restriction member on the game board surface based on the value of the random number determined when a certain condition is achieved during the game. Output a control signal.

In any case, the driving means drives the prize-winning restriction member so that the prize-winning restriction member takes a position corresponding to the control signal.

As described above, the winning restriction member is positioned between a position that prevents the game ball from entering the winning opening and a position that does not prevent the gaming ball from entering the winning opening, and the winning rate can also be finely controlled.

Further, the prize limiting member is formed by a rod-shaped member that can project from the back side of the game board surface to above the winning opening, and the position of the prize limiting member can be changed by using a ball screw as a driving means for projecting the rod-shaped member from the game board surface. Can be adjusted precisely.

[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,
In addition to the normal variable winning a prize opening 3, a plurality of winning a prize openings 5 in which the winning of a hit ball is controlled by a winning restriction member 4 are provided. The winning restriction member 4 and its driving means will be described later in detail. Above each of the winning openings 5, a detector 6 described later is arranged as a passing ball detecting means for detecting a game ball (passing ball) passing on the game board surface 2. Further, a large number of nails 7 are arranged as hitting ball guiding means for guiding the pachinko ball hit on the game board surface 2 to the upper part of each winning opening. A ball hitting handle 8 is provided on the lower right side of the front part, and when the player operates it, a pachinko ball is hit 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, the winning opening 5 has a U-shaped cross section in which the pachinko balls P are received one by one in the bowl-shaped opening 21 facing the game board surface 2 and sent out to the back side of the game board surface 2. It is formed by the ball receiving member 22.

The prize-winning restricting member 4 positioned above the winning opening 5 is a rod-shaped member that penetrates through a hole provided in the game board surface 2 and is attached so as to project to the front side. This rod-shaped member is driven perpendicularly to the game board surface 2 by a driving means composed of a ball screw. That is, as shown in FIG. 3, a male screw portion 24 of a ball screw is rotatably supported by a U-shaped bracket 23 attached to the back side of the game board surface 2, and protrudes upward from a female screw portion 25 screwed around the male screw portion 24. The rear end of the rod-shaped member is fitted and connected to the projection 26. The male screw part 24 is a pulse motor
It is connected to 27 axes.

Therefore, when the pulse motor 27 is driven to rotate the male screw portion 24, the female screw portion 25 moves along the male screw portion 24, and the prize-winning restricting member 4 is projected and retracted perpendicularly to the game board surface 2. At this time, the movement amount of the winning restriction member 4 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 prize regulating member 4 protruding from the game board surface 2 can be adjusted to regulate the prize of the pachinko ball P in the opening 21. .

It is preferable to install a decorative plate 30 that covers the winning restriction member 4 so that it cannot be seen outside the winning opening 5.

Next, as the passing ball detector 6 arranged above the winning opening 5 on the game board surface 2 shown in FIG. 1, for example, a magnetic sensor having a circular passing hole can be used. This is to detect the passing sphere from the change in the magnetic field when the pachinko ball passes through the passing hole. 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.

In the winning ball passage provided on the back side of the game board surface 2, as a winning ball detecting means for detecting a gaming ball that has won the winning opening 5, a winning ball detector 28 (fourth) which is the same sensor as the passing ball detector 6 is provided. Figure) is arranged. This detector detects a pachinko ball (winning ball) that has entered the ball receiving member 22.

As described above, the prize-winning restriction member 4 protruding above the winning opening 5
Is driven in a direction perpendicular to the game board surface 2 by a driving means including a ball screw composed of a male screw portion 24 and a female screw portion 25, and a motor 27. The rotation of the motor 27 is controlled by a movement control means described below. It is controlled by the control device 29 including. The movement control means causes the prize-winning restricting member 4 to appear and disappear from the game board surface 2 so that the prize-winning rate becomes a value set by an external device or a predetermined value.
It is configured as shown in the figure.

The movement control means 40 of FIG. 4 receives the detection signals from the passing ball detector 6 and the winning ball detector 28, 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 pulse motor 27 based on the determination result. The drive circuit 47 connected to the pulse motor 27 drives the motor according to the control signal output from the movement control means 40.

The setting device 44 is a means for setting and holding the winning rate of the pachinko ball for each winning opening to a desired value, and the configuration thereof includes a plurality of key input portions for inputting numbers and the like and input data. A storage unit for storing may be used. The value set by this device can be changed appropriately.

The comparison calculation means in the control means 40 is, for example, as follows. 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 position of the winning restriction member 4 is controlled so that the value becomes the value set by the setting device 44. . In this way, if the winning rate to each winning port 5 is set to, for example, 80%, this winning rate can be achieved for all winning ports of the same type. In addition, each prize hole 5
It is also possible to set different winning rates with respect to, so that the winning rate falls within a certain range as a whole.

Such movement control means can be realized by a microcomputer. In that case, the microcomputer controls each part of the pachinko gaming machine while controlling the movement of the winning restriction member 4, so that the winning rate set by the setting device 44 is stored and the passing ball detector 6 and the winning ball are won. The number of passing balls, winning balls, and other data obtained from the output of the ball detector 28 are stored in a storage device 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. The determination unit 53 determines the position of the winning restriction member 4 corresponding to the random number, and the control signal output unit 54 outputs a signal for controlling the driving of the pulse motor 27 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, or when any other arbitrarily determined condition is achieved. According to the signal output from the movement control means 50, the motor drive circuit
Driving of the pulse motor 27 by 47 is 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, and this range is divided into ranges corresponding to some positions of the winning restriction member 4. Then, the determination unit 53 determines a range to which the random number value determined as described above belongs, and drives the winning restriction member 4 so as to come to a position corresponding to the range. In this case, the classification of the random numbers determined by the determination unit 53 can be changed as appropriate by input from the external setting device.

Thus, according to the embodiment, the prize-winning restricting member 4 is precisely controlled in the direction in which it projects from the game board surface 2, and takes a position corresponding to an arbitrarily set winning rate. This makes it possible to comprehensively manage the winning rate and eliminates the conventional nail adjustment. Further, the movement range of the winning restriction member 4 can be arbitrarily set between a position that prevents the pachinko ball from entering the winning opening 5 and a position that does not prevent it.

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. Further, the winning restriction member is not limited to the direction projecting from the game board surface, but may be moved above and below the winning opening in any direction such as left, right, up and down. Further, the shape of the winning restriction member, the configuration of the driving means and the control means, and the like can be arbitrarily designed in addition to the example shown in the drawing.

[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 automatically adjusting the position of the winning restriction member. 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.
