Description

  The present invention is arranged below the obstacle nail group that is arranged in a substantially straight line on the game board surface and tilts downward to the left or right side of the game board surface to receive and guide the game ball. The present invention relates to an auxiliary nail member of a gaming machine in which an inclination angle with respect to a horizontal plane can be changed.

Recently, in a pachinko machine that is a type of gaming machine, a large display device that displays information such as numbers, symbols, etc. is displayed at the center of the gaming part surrounded by guide rails, and a starting prize is placed below it. When the information is changed by attaching a mouth and a winning device, and the game ball is won at the starting winning opening, and when the information at the time of stopping is aligned with a specific display (for example, “777”), An advantageous special gaming state in which the open / close door of the winning device is opened and a large number of winning balls can be obtained at a time under certain conditions has been well received (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 9-19546 (2nd page, paragraph 0009, FIG. 1)

  By the way, recently, there is a tendency to increase the size of the display device in order to increase the interest of the game, and to widen the display portion both vertically and horizontally. However, a start winning opening and a winning device are arranged vertically below the display device, and arranged on both sides of the starting winning opening in a substantially straight line on the game board surface and either one of the left and right sides of the game board surface. A group of obstacle nails that are tilted downward to receive a game ball and guide it to, for example, a start winning opening is mounted.

  More specifically, all of the substantially straight impact nail groups arranged on the left and right sides of the start winning opening are inclined downward toward the center, that is, the starting winning opening, and the inclination angle is relative to the horizontal plane. Is set to approximately 30 degrees. Usually, the obstacle nails are driven between nails, and each obstacle nail has a head having a larger outer diameter than the normal shaft diameter. It is not possible to make a certain interval between adjacent obstacle nails.

  For this reason, if the inclination angle of the substantially straight obstacle nail group is set to be gentler than 30 degrees, the position of the center of gravity of the game ball settles between the obstacle nails, and the game ball stays between the obstacle nails. There is a possibility that it will not flow. Accordingly, the impingement nail group cannot be lowered in inclination angle to 30 degrees or less with respect to the horizontal plane. This can be cited as one factor that hinders the desire to increase the size of the display device from a different perspective.

  Therefore, the present invention has been made in view of the above problems, and it is possible to lower the inclination angle of the substantially straight obstacle nail group below a specified angle, and to increase the gauge of the game board surface such as an increase in the size of the display device. It is an object of the present invention to provide an auxiliary nail member for a gaming machine in which the degree of freedom is increased and the interest of the game is enhanced.

  In order to achieve such an object, the auxiliary nail members of the gaming machine according to the present invention are arranged in a substantially straight line on the game board surface, and tilt downward to the left or right side of the game board surface to receive and guide the game ball. A plurality of ridges are arranged below the obstacle nail group, and are arranged in parallel to the center of each obstacle nail in the obstacle nail group so as to be flush with the obstacle nail. Further, the present invention can be applied to both the upper and lower obstacle nail groups on the game board surface.

  At this time, each of the protrusions is preferably formed into an arc surface whose width in the direction orthogonal to the axial direction is substantially the same as the shaft diameter of the obstacle nail and whose upper surface is substantially the same as the peripheral surface of the obstacle nail.

  The auxiliary nail member of the gaming machine according to the present invention is disposed below the obstacle nail group, and is positioned substantially parallel to the center between the adjacent obstacle nails in the obstacle nail group and is flush with the obstacle nails. A plurality of ridges arranged in a row, the space between the obstacle nails of the obstacle nail group is substantially narrowed, whereby the inclination angle of the substantially straight obstacle nail group with respect to the horizontal plane is 30 degrees or less. For example, even if it is 20 degrees, there is no possibility that the game ball settles between the obstacle nails and stays there. Therefore, the degree of freedom of the game board surface can be expanded correspondingly, and the display device can be increased in size, and as a result, the interest of the game is enhanced.

  In addition, each protrusion of the auxiliary nail member has a width in a direction perpendicular to the axial direction thereof that is substantially the same as the shaft diameter of the obstacle nail and the upper surface is formed into an arc surface that is substantially the same as the peripheral surface of the obstacle nail. There is an effect that the rebound of the game ball received on the upper surface of the strip becomes familiar with each obstacle nail and is easy to play.

  Hereinafter, embodiments of an auxiliary nail member of a gaming machine according to the present invention will be described with reference to the drawings. Note that the gaming machines include, for example, pachinko gaming machines, arrange ball machines, and sparrow ball gaming machines. In the present invention, a pachinko gaming machine will be described as an example. FIG. 1 is a front view of a pachinko gaming machine to which the present invention is applied. The pachinko gaming machine P has a wooden outer frame 1 on the outer side, and a front frame 2 is attached to the front surface of the pachinko gaming machine P so as to be freely opened and closed. A game board 3 is installed on the front frame 2.

  On the front surface of the front frame 2, a transparent plate holding frame 4 that covers the front surface of the game board 3 is disposed at an upper portion thereof so as to freely open and close with one side as a fulcrum. The transparent plate holding frame 4 is formed of a synthetic resin material, and a window opening 5 is opened at the center. A glass plate 6 that is a transparent plate is attached to the window opening 5 so as to close the window opening 5. The front surface of the game board 3 can be viewed from the front side through the window opening 5.

  Further, the front plate 7 is pivotally mounted on the front surface of the front frame 2 below the transparent plate holding frame 4 so as to freely rotate about one side as a fulcrum, like the transparent plate holding frame 4. On the front surface of the front plate 7, a hit ball supply tray 8 for storing game balls supplied to a hit ball launching position (not shown) is mounted. A surplus ball receiving tray 9 for storing game balls overflowing from the hitting ball supply tray 8 is mounted on the lower front surface of the front frame 2. On one side, an operation handle 10 is provided that can freely rotate to adjust the hitting force of a game ball as a hit ball.

  A game portion 3a is formed on the front surface of the game board 3 surrounded by inner and outer guide rails 11a and 11b laid in a spiral shape. The game unit 3a is equipped with a large display device 12 which is located in the center and displays information such as numbers and symbols in a variable manner. In addition, when information on the start winning opening 13 for changing the information by winning a game ball and information on the display unit 12a of the display device 12 are aligned on a specific display (for example, “777”) below, a certain condition is satisfied. Each of the large winning devices 14 is equipped with a large number of winning balls at a time.

  The winning device 14 is provided with a ball inlet 17 which is closed by an opening / closing door 16 which is tilted back and forth freely on a mounting plate 15 attached to the surface of the game board 3, and a normal winning hole (not shown) is formed therein. ) And a V winning hole (not shown). Further, on the both sides of the ball entrance 17, normal winning holes 18 and 18 are attached to the mounting plate 15. Below the winning device 14, an out ball opening 19 is provided for discharging a game ball that has been driven into the game unit 3a and has not won a prize as an out ball to the back side of the game board 3.

  Therefore, for example, when the game ball B that is driven into the game unit 3a wins the start winning opening 13, the information on the display unit 12a of the display device 12 changes. When the information stops fluctuating and the information at the time of the stop is aligned with a specific combination (for example, “777”) and the player enters a special gaming state advantageous to the player, the door 16 is tilted forward. Many game balls B will win the ball entrance 17 at a time.

  However, the opening / closing door 16 rises to the rear side and closes when ten game balls win the ball entrance 17 or when a predetermined time has elapsed (30 seconds have elapsed since the opening / closing door 16 tilted forward). It has become. In the meantime, when at least one game ball B wins the V winning hole, ten game balls B win or the opening / closing door 16 tilts forward again after a predetermined time and the ball entrance 17 opens. This operation is repeated a prescribed number of times (for example, 16 times) on condition that the game ball B wins the V winning hole, so that many game balls B can be obtained. When the prescribed number of times is completed, the opening / closing door 16 returns to the original standing position where the game ball is not won and the ball entrance 17 is closed.

  By the way, in the gaming portion 3a on the surface of the gaming board 3, the substantially straight obstacle nail groups 20 and 20 are arranged on both sides of the start winning opening 13, respectively. Each obstacle nail group 20 has a plurality of obstacle nails 21 separated from each other by a predetermined distance and is planted on the surface of the game board 3 and arranged in a substantially straight line. In the case, it is tilted down to the center start winning prize side). Then, the auxiliary nail member 22 is arranged close to the lower side of the obstacle nail group 20 on one side (for example, the left side in FIG. 1). The auxiliary nail member 22 can loosen the inclination angle of the obstacle nail group 20 with respect to the horizontal plane, and is formed of a synthetic resin material. This material is not limited to synthetic resin but may be made of metal or ceramics.

  As shown in FIG. 2, the auxiliary nail member 22 has a horizontally long mounting plate portion 23 for mounting on the game board 3 surface, and is substantially perpendicular to the game board 3 surface along the upper edge of the mounting plate portion 23. A belt-like auxiliary plate portion 24 is integrally provided. On the upper surface of the auxiliary plate portion 24, a plurality of protrusions 25 are arranged in parallel along the longitudinal direction at equal intervals in a direction orthogonal to the longitudinal direction. Further, on the upper surface of the auxiliary plate portion 24, between the protrusions 25, a receiving portion 26 having a predetermined height lower than the protrusions 25 is provided in the center in the same manner. Screw insertion holes 27 are formed at both ends of the mounting plate portion 23.

  The distance between the adjacent protrusions 25 is set to be approximately the same as the distance between the obstacle nails 21 and 21 of the obstacle nail group 20. In addition, each protrusion 25 has a width in a direction orthogonal to the axial direction thereof that is substantially the same as the shaft diameter of the obstacle nail 21 and an upper surface formed into an arc surface substantially the same as the peripheral surface of the shaft portion 21a of the obstacle nail 21. Is done. However, the upper surface of each protrusion 25 is not limited to the circular arc surface, and may be a polygonal shape, for example.

  Each receiving portion 26 has an upper surface 26 a formed into a concave arc surface. When the auxiliary nail member 22 is installed at a predetermined position below the obstacle nail group 20, the upper surface 26 a of each receiving portion 26 is brought into contact with the lower surface of the shaft portion 21 a of each obstacle nail 21. . Thereby, the height position of each protrusion 25 with respect to each obstacle nail 21 of the obstacle nail group 20 is set to be flush with each other. That is, each ridge portion 26 is arranged such that each ridge 25 is flush with each obstruction nail 21 when the upper surface 26a of each ridge portion 26 abuts the lower surface of each obstruction nail 21, and The height and position of each protrusion 25 are set so that each protrusion 25 is positioned approximately at the center between the adjacent obstacle nails 21 and 21.

  As shown in FIGS. 3 and 4, the auxiliary nail member 22 formed in this manner is made to approach the lower side of each of the obstacle nails 20 on the left side, and the upper surface 26 a of each receiving portion 26 is formed on each of the obstacle nails 21. It arrange | positions so that it may contact | abut to the lower surface of the axial part 21a. Each protrusion 25 is arranged substantially parallel to the center of each obstacle nail 21 and is flush with each obstacle nail 21 and is substantially straight and aligned on a plane. In this state, a screw 28 is inserted into each screw insertion hole 27 and screwed. Thereby, the auxiliary nail member 22 is fixed to the game board 3 surface. At this time, each protrusion 25 and each receiving portion 26 are located on the rear side of the head 21b of each obstacle nail 21, and are not so conspicuous even when viewed from the front side. In addition, the protrusion 25 is not hung on the obstacle nails 21 and 21 located at both ends of the obstacle nail group 20. This is because the auxiliary nail member 22 gets in the way when the nails 21 and 21 are frequently adjusted.

  In the present invention, as described above, the ridges 25 are arranged in parallel so as to be in parallel with each obstacle nail 21 and in the center between the obstacle nails 21 adjacent to each other in the obstacle nail group 20. As a result, the distance between the obstacle nails 21 of the obstacle nail group 20 is substantially reduced. As a result, there is no risk that the game ball B will settle down and stay between the obstacle nails 21, and the inclination angle of the substantially straight obstacle nail group 20 with respect to the horizontal plane will be 30 degrees or less, for example, 20 degrees. Is also possible. Therefore, the degree of freedom of the game board 3 is expanded correspondingly, and the display device 12 can be increased in size.

  Although not shown, the auxiliary nail member 22 is provided with a lens portion by expanding the mounting plate portion 23, and on the other hand, a light emitting body such as an LED is disposed on the back side of the lens portion to emit light, thereby providing an illumination function. You may make it add.

  It is conceivable to use, for example, a flat synthetic resin strip instead of the obstacle nail group 20, but this lacks the elasticity to play the game ball B peculiar to the obstacle nail 21 appropriately. The movement will become extremely monotonous, and the fun of the game will be halved. Therefore, it is difficult to employ the strip.
