Description

  The present invention relates to a ball launch path formed on a game board of a pachinko gaming machine, and more particularly to a ball launch path that can reliably prevent an illegal prize ball from being obtained using an illegal game ball.

Conventionally, in pachinko machines (hereinafter referred to as pachinko machines) as an example of gaming machines, so-called goto acts have been frequently used to obtain illegal prize balls by various methods. It is known to cause unexpected damages.
In recent years, as a gothic act, a ball that has been threaded through an adhesive or the like (hereinafter referred to as a ball with a thread) to a game ball (hereinafter referred to as a ball) that is lent out by an amusement store is self-made, and a thread that is connected to the ball. While being held by hand, a threaded ball is loaded into the launching mechanism of a pachinko machine and a threaded ball is fired into the game area.
More specifically, when the threaded ball reaches the game area, the thread connected to the ball is caught by the tip of the ball return prevention valve provided on the inner guide rail constituting a part of the ball launch passage.
The fraudster then manipulates the thread held by hand with the tip of the ball return prevention valve as a fulcrum, thereby freely manipulating the threaded ball that has reached the game area and distributing the threaded ball to the game board. By repeatedly pulling the thread held in the hand (lifting operation) after being taken into the established start prize opening and general prize opening, the ball with thread is repeated by the prize detection sensor provided inside the above-mentioned game parts. Detect a large number of illegal prize balls in a short time.
Such a goto action has a tremendous disadvantage to a game store or a general player. Therefore, it is desirable to take specific measures corresponding to the goto action. Currently, no measures have been found.

Enter the game area 11A surrounded by.

The ball launch passage 20 is on the surface 11B of the game board 11 on the outer guide rail 18 on the surface 11B of the game board 11 and on the game area 11A side of the outer guide rail 18 along a part of the outer guide rail 18. The inner guide rail 17 is provided, and a ball return prevention valve 31 extending from the tip 30 of the inner guide rail 17 to the outer guide rail 18 side.
The outer guide rail 18 and the inner guide rail 17 are band-like plates made of metal or synthetic resin, and are arranged in an arc shape so as to be orthogonal to the surface 11B of the game board 11 and facing each other. Is done.
Then, the ball launched by the unillustrated launching mechanism passes between the outer guide rail 18 and the inner guide rail 17, and the ball return provided so as to close the outer guide rail 18 and the inner guide rail 17. The prevention valve 31 is pushed open to reach the game area 11A.

As shown in FIG. 2, the ball return prevention valve 31 includes a valve holder 38 fixed to the game board 11 at a position in the vicinity of the distal end portion 30 of the inner guide rail 17, and a valve body held on one side by the valve holder 38. 37.
The valve holding body 38 is a member made of, for example, a synthetic resin, and includes a locking groove 38A that holds the valve body 37 and a plurality of through holes 38B that penetrate the game board 11 in the vertical direction.
As shown in FIG. 2B, a nail 38C as a fixing means is inserted into the through-hole 38B, and the nail 38C is driven into the game board 11, so that the valve holder 38 extends along the surface of the inner guide rail 17. It is fixed in the state. The locking groove 38A includes a circular groove through which the root 37A of the valve body 37 formed by winding can be inserted, and a linear groove extending from the periphery of the circular groove.

  As shown in FIG. 2C, the tip 37B of the valve body 37 on the outer guide rail 18 side, that is, the tip 37B of the valve body 37 in the extending direction side is the window 12A side, that is, the game board 11 side. It is formed as a sword-tip-like surface that is gradually inclined downward toward the front.

When a ball is launched into the ball launch passage 20 having the above-described configuration, the launched ball is guided to the game area 11 </ b> A side by drawing an arc-shaped locus along the outer guide rail 18 by centrifugal force.
Then, when the ball contacts the valve element 37 of the ball return prevention valve 31 extending from the inner guide rail 17 side toward the outer guide rail 18 side so as to close the space between the outer guide rail 18 and the inner guide rail 17, The valve body 37 bends toward the game area 11A due to its elastic force, allows the ball to enter the game area 11A, and returns to its original position due to the elastic force when the ball has passed.
In a state in which the valve body 37 is returned to the original position, the distance between the distal end portion 37B of the valve body 37 and the outer guide rail 18 is set to be less than the diameter of one sphere.
That is, the ball launched to the game area 11 </ b> A always enters the game area 11 </ b> A after contacting the valve element 37, and the ball that has once reached the game area 11 </ b> A does not return to the ball launch path 20.

Hereinafter, the operation of the tip portion 37B will be described with reference to the respective drawings in FIG.
As shown in FIG. 2, when the threaded ball P is launched and reaches the game area 11A via the ball launching passage 20, the threaded ball P is connected to the threaded ball P by the threaded ball P. 11, the tip 37 </ b> B of the valve body 37 is touched as it flows down, but as described above, the tip 37 </ b> B is formed as a surface inclined downward toward the front of the game board 11. The thread Q touching the tip 37B is guided to slide toward the front of the game board 11, and falls off the game board 11 from the tip 37B as indicated by a chain line in FIG. Become.
That is, according to the ball return prevention valve 31 according to the present embodiment, the tip end portion 37B that is the end portion in the extending direction of the valve body 37 is formed so as to be inclined downward toward the front of the game board 11. Thus, it is possible to reliably prevent the fulcrum necessary for the “thread goto” from being formed in the ball return prevention valve 31 and to reliably prevent an illegal act using the threaded ball P.

  Hereinafter, other embodiments according to the present invention will be described together with a plurality of components arranged on the game board 11. As shown in FIG. 1, on the game board 11, in addition to the inner guide rail 17 and the outer guide rail 18 constituting the ball launching passage 20, the game board 11 surrounds the periphery of the mounting hole of the liquid crystal display opened at the center. Board decoration 70, a normal symbol starting part 71 located on the side of the board decoration 70, a start winning part 72 located in the center below the board decoration 70, and a plurality of left and right located below the starting prize part 72. The general winning component 73, the large winning component 74 located in the center below the starting winning component 72, and a large number of guide nails 75 that distribute the flow direction of the sphere flowing down in the game area 11A are arranged.

The board decoration 70 has a roof portion 70A; 70A inclined downward in the left-right direction with the center of the game area 11A as a boundary, and a wall portion 70B; 70B extending downward from the roof portion 70A; The board decoration 70 is a member made of a synthetic resin or the like that protrudes forward from the surface 11B of the game board 11, and a ball that is launched into the game area 11 </ b> A in a state where the window 12 </ b> A is closed is on the front side of the board decoration 70. Cannot flow down from the sphere, and the sphere flows down along the wall portions 70B and 70B via the roof portions 70A and 70A.
The normal symbol starting component 71 is formed in a gate shape that is open up and down, and has a gate 71 </ b> A that projects forward of the game board 11. The gate 71A has a sphere detector such as a proximity sensor inside, and can detect a sphere passing through the gate. In addition, the sphere that flows down around the normal symbol starting component 71 in the state where the window 12A is closed cannot flow down from the front side of the gate 71A, and the sphere passes through the gate 71A or laterally through the gate 71A. To flow down.

The start winning component 72 is configured so as to block the front plate 72B, which is spaced apart from the base plate 72A disposed on the game board 11 by a diameter equal to or more than one ball, and both sides of the front plate 72B. It comprises a pair of open / close bodies 72C arranged.
The start winning component 72 is a component that can take in a sphere from a gap (take-in port) between the base plate 72A and the front plate 72B, and the sphere that flows down around the start winning component 72 enters the inside from the upper gap. In the state where the opening / closing body 72C is opened in the left-right direction by driving a solenoid (not shown), the opening / closing body 72C is taken in from the left and right gaps. In addition, the ball cannot flow down from the front side of the front plate 72B and the front side of the opening / closing body 72C, which are separated forward from the surface of the game board 11 in a state where the window 12A is closed.

The general winning component 73 is a cylindrical member that protrudes forward from the surface 11B of the game board 11 and can take in a ball from a not-shown intake port that is opened upward. In addition, the sphere that flows down around the general winning component 73 in a state where the window 12A is closed cannot flow down from the front side of the general winning component, and the sphere is taken into the inside through a take-out port that is not shown. Or, the general winning component 73 is deflected to the side and flows down.
The big winning component 74 is composed of a rectangular winning opening (not shown) opened in the game board 11 and an opening / closing body 74A for closing the winning opening. The opening / closing body 74A is pivotally supported below the winning opening, and is opened forward by driving a solenoid (not shown) with the lower portion of the winning opening as a fulcrum. Further, the ball flowing down around the big winning component 74 when the window 12A is closed does not flow down from the front side of the opening / closing body 74A when the opening / closing body 74A is opened, and is guided to the opening / closing body 74A and won a prize. It is taken into the mouth or flows away from the big prize part 74.
In addition, a large number of guide nails 75 are implanted in the game board 11, and the balls that have reached the game area 11 </ b> A flow down while being guided in various directions by the guide nails 75.
As described above, on the game board 11, in addition to the inner guide rail 17 and the outer guide rail 18, various parts related to the game that protrude forward from the surface 11 </ b> B of the game board 11 by a predetermined height (width) are arranged. The thread Q that has fallen off from the ball return prevention valve 31 according to the above-described embodiment is caught by these parts, and there is an element that can be a fulcrum of “thread goto”.
The parts arranged on the game board 11 are not limited to the above parts. For example, a windmill member that changes the direction of the ball, an accessory mechanism having a specific winning opening that triggers a big hit, etc., the window 12A In the closed state, all parts whose distance from the window 12A is equal to or less than the diameter of one sphere are targeted.

Hereinafter, with reference to FIG. 3, the ball return prevention valve 31 which concerns on other embodiment is demonstrated. In the following description, the guide nail 75 having the highest protrusion height from the surface 11B of the game board 11 is taken as an example.
FIG. 3 shows the relationship between the protrusion height (width) of the valve element 37 of the ball return prevention valve 31 and the protrusion height of an arbitrary guide nail 75 implanted in the game board 11, and the valve element in this embodiment. The protruding height of 37 is arranged so as to be higher than the protruding height of the guide nail 75 in the state of being directly arranged on the inner guide rail 17 by the valve holder 38.
More specifically, the distance X3 from the surface 11B of the game board 11 to the side surface 37C of the valve body 37 is set to be longer than the distance X4 from the surface 11B of the game board 11 to the head 75A of the guide nail 75. Of all the components arranged on the game board 11, the valve body 37 is arranged so that the protruding height (width) is the highest.

By disposing the valve body 37 to have the above-described configuration, the thread Q guided forward along the tip portion 37B formed as an inclined surface is more than the number of components disposed on the game board 11. The guide nail 75 disposed on the game board 11 and the like when the thread Q falls downward between the valve body 37 and the window 12A will fall off from a position away from the front of the game board 11. It is possible to significantly reduce the possibility of being caught by these parts.
Therefore, it is possible to prevent a necessary fulcrum for the “thread goto” from being created on the game board 11 and to reliably prevent an illegal act using the ball with thread P.

FIG. 4 is a schematic diagram showing the relationship between the ball return prevention valve 31 and the guide nail 75 according to another embodiment. In the drawing, the valve element 37 of the ball return prevention valve 31 is different from the above embodiment in that a part of the protruding height in the extending direction is higher than the protruding height of the guide nail 75.
More specifically, the valve body 37 has a wider width X3 from the surface 11B of the game board 11 to the side surface 37C of the valve body 37 than the distance X4 from the surface 11B of the game board 11 to the head 75A of the guide nail 75. Portion 50 and a narrow portion 51 where a distance X3 from the surface 11B of the game board 11 to the side surface 37C of the valve body 37 is shorter than a distance X4 from the surface 11B of the game board 11 to the head 75A of the guide nail 75. The shape widens in the extending direction.

  The thread Q guided to the front of the wide portion 50 along the tip portion 37B formed as an inclined surface even if the valve body 37 is shaped as described above is more than the guide nail 75 and many components arranged in the game board 11. The thread Q will fall off from a position away from the front of the game board 11, and when the thread Q falls downward between the valve body 37 and the window 12A, it will be caught by other parts arranged on the game board 11. The possibility can be significantly reduced.

FIG. 5 is a schematic diagram showing the relationship between the ball return prevention valve 31 and the guide nail 75 according to another embodiment. In the figure, the valve element 37 of the ball return prevention valve 31 differs from the above embodiment in that the protruding height at one point in the extending direction is higher than the protruding height of the guide nail 75.
More specifically, the valve body 37 is formed in a substantially triangular shape formed by a slope 55 in which a part of the side surface 37C is inclined forward and gradually inclined forward and a slope 56 gradually inclined forward and upward. The distance X3 from the surface 11B of the game board 11 to the vertex T is set to be longer than the distance X4 from the surface 11B of the game board 11 to the head 75A of the guide nail 75.

  Even when the valve body 37 has the above shape, the thread Q that has fallen from the tip end portion 37B formed as an inclined surface falls along the slope 55 when falling between the valve body 37 and the window 12A downward. Guided nails 75 and other parts arranged on the game board 11 are guided to the vertex T farther away from the game board 11 than the many parts arranged on the board 11 and fall off from the vertex T. It is possible to remarkably reduce the possibility of being caught.

  As is clear from the above-mentioned other forms, the valve element 37 of the ball return prevention valve 31 has a part higher than the protruding height of the parts arranged on the game board 11 with respect to the surface 11B of the game board 11. It is only necessary to include this, and by adopting this configuration, it is possible to significantly reduce the possibility that the thread Q will be caught by other parts on the game board 11 other than the valve body 37.

  As described above, the present invention has been described through the respective embodiments. However, it is apparent to those skilled in the art that the technical scope of the present invention is not limited to the above-described embodiments, and various changes and improvements can be made. Further, it is apparent from the scope of the claims that the embodiments added with such various changes and improvements can be included in the technical scope of the present invention.
