FIG. 1 shows a front view of the 100 and the pachinko gaming machine 200 according to the embodiment. FIG. 2 shows a game board 100 used in the pachinko game machine 200. The embodiments and drawings described below exemplify a part of the embodiments of the present invention, are not used for the purpose of limiting to these configurations, and do not deviate from the gist of the present invention. Can be changed as appropriate in. The corresponding components in each figure are designated by the same or similar reference numerals. For convenience of explanation, in the present specification and claims, the right side, the left side, the upper side, and the lower side indicate the directions of the arrows in FIG.

The game board 100 used in the pachinko game machine 200 according to the present invention is made of plastic or ceramic such as polycarbonate and acrylic. As shown in FIG. 1, the game board 100 has a game area 10 surrounded by guide rails 11 on the front side of the game board 100, and an outer guide arranged on the outside is provided on the left side of the game area 10. The game ball guide passage 12 for guiding the game ball to the game area 10 is formed by the rail 11a and the inner guide rail 11b arranged inside. The game area 10 mainly includes a plurality of obstacle protrusions 15, a fixed small winning opening 21, a movable small winning opening 22 (22a, 22b, 22c, 22d), two large winning openings 30, and a pendulum type. It is equipped with a work-in-process 40, an out port 70 for collecting non-winning game balls, a windmill 16 arranged at a position corresponding to a top nail, and an eccentric rotating windmill 17 arranged in a vertical row from the center to the left and right. ing. The mechanisms and arrangements of the small winning opening 22, the large winning opening 30, the pendulum type work in process 40, the wind turbine 16, the eccentric rotating wind turbine 17, and the like in the game area 10 described below are examples, and are not limited thereto. Absent.

The obstruction protrusion 15 replaces the conventional obstruction nail and is formed of a plastic or ceramic protrusion. The obstacle protrusion 15 has a triangular cross section, and is arranged so that the apex of the corner is upward. The corners of the obstacle protrusion 15 are chamfered in a circular shape in order to prevent the corners from being chipped due to collision by the game ball. Further, as shown in FIG. 3A, a protective member 15a made of a metal such as stainless steel or titanium may be arbitrarily attached to the corner portion forming the apex of the triangle. The protective member 15a may be integrally molded at the time of forming the game plate by insert molding, or may be attached by fitting the protective member 15a made of another member in a later step. The obstacle protrusion 15 is preferably formed to have a side length of about 3.0 mm to 10.0 mm in order to prevent damage due to the game ball. The arrangement of the obstacle protrusions 15 can be arbitrarily selected, but in the present embodiment, a plurality of rows (α) arranged horizontally at the same interval δ are formed, and a plurality of these rows are formed, and the upper and lower rows are formed. Lines are arranged so as to be offset by 1/2 of the above-mentioned intervals, except for places where the obstacle protrusions 15 cannot be arranged due to the winning openings and the pendulum type work-in-process 40 (see the relationship between α and α1). Therefore, these obstacle protrusions 15 are arranged so as to be diagonally straight. For example, a plurality of diagonally arranged ones (β) descending to the right and a plurality of diagonally arranged ones (γ) descending to the left are formed. By arranging in this way, the game ball can easily flow diagonally in a straight line, and by arranging the small winning opening 20 and the large winning opening 30 in the flowing direction, it is easy to allow the game ball to enter these winning openings. Become.

Further, a lighting fixture 18 such as an LED is arranged on the back side of the obstacle protrusions 15, and the obstacle protrusions 15 are formed so as to be capable of emitting light. As shown in FIGS. 3A and 3B, the obstacle protrusion 15 is formed with a hole 15b having an opening on the back surface side, and has a hollow portion formed of a hollow cavity inside. A streak-like unevenness 15c is formed on the inner surface of the cavity, and the light emitted from the luminaire toward the hole 15b is reflected and refracted by the streak-like unevenness 15c, and the entire obstacle projection 15 shines when viewed from the front side. You can make it look like you are. By arranging such a luminaire 18 on each of the plurality of obstacle protrusions 15 and illuminating the luminaire 18 in a timely manner (for example, illuminating in rainbow colors), the effect can be exhibited. In addition, characters, patterns, and the like can be expressed by selecting the obstructive protrusion 15 to be illuminated. It is also possible to express a sense of season and time by the pattern illuminated by the obstacle protrusion 15. For example, when it reminds us of spring, it shines in the pattern of cherry blossoms, and when it reminds us of winter, it shines in the form of a snowman. In addition, by expressing the shape of the constellations and the phases of the moon, it is possible to remind us of the moon from January to December and to express the time. As described above, in the game board according to the present invention, the design of a large range of the game board can be changed not only by the liquid crystal region as in the conventional pachinko machine but also by the portion having the obstacle protrusion 15. Further, since such a design can be changed at any time during business, it is possible to make a game machine having a design having a significantly different impression even in the same game machine. As the lighting fixture 18, it is preferable to use a type in which light does not directly emit to the front side but shines in the lateral direction. By using such a luminaire 18, it is possible to prevent the player from being directly exposed to light from the luminaire 18.

The obstacle protrusion 15 may be integrally formed with the game plate 100, or as shown in FIG. 4, only the obstacle protrusion 15 is formed, and a hole into which the obstacle protrusion 15 can be inserted is provided in the game plate 100. It may be formed so that the obstruction protrusion 15 is inserted into this hole. As described above, by adopting the insertion type, the manufacturing cost can be reduced as compared with the case of integrally molding. The insertion direction may be from the front side as shown in FIG. 4A or from the back side as shown in FIG. 4B. At this time, it may be fixed with an adhesive or the like so that the obstacle protrusion 15 does not easily come off.

Further, the obstruction projection 15 has a substantially triangular cross section in the above-described embodiment, but is not limited to this, and as shown in FIG. 5A, the obstruction projection 15 has a substantially circular cross section, as shown in FIG. 5B. As described above, the cross-sectional shape may be substantially rhombic, and the cross-sectional shape is not particularly limited. In this case, the widest portion of the cross section of the obstacle protrusion 15 may be formed to have a thickness of about 3.0 mm to 10.0 mm.

The small winning opening 20 is a so-called mechanical winning opening, and has a fixed small winning opening 21 and a movable small winning opening 22.

An arbitrary number of fixed small winning openings 21 are appropriately selected and attached. When the fixed small winning opening 21 enters the fixed winning opening, a predetermined number of winning balls are paid out. The fixed small winning opening 21 is not particularly limited, but in the present embodiment, as shown in FIG. 6, it is formed in a tubular shape having both side surfaces 21a and a front surface 21b and having open top and bottom. The front surface 21b is formed with a groove 21d formed from the upper end to the lower end. By providing such a groove 21d, the player can visually recognize until the moment when the game ball wins a prize. On the back surface of the front surface 21b, an inclined surface 21c is provided so as to be lowered toward the back surface side. The inclined surface 21c guides the game ball to the back surface side and guides it to the winning opening.

In the present embodiment, the movable small winning opening 22 employs a non-electric tulip-shaped winning opening, but the present invention is not limited to this. An image display device 60 is provided in front of the movable small winning opening 22. The image display device 60 is provided so that at least a numerical value can be displayed, and a device having a function of displaying a counter is used. For example, a liquid crystal monitor, an organic EL, a monitor using a dot matrix, a seven-segment display, or the like can be mentioned. The image display device 60 determines how many game balls have entered each movable small winning opening 22 by a signal from a detection member that detects the number of gaming balls that have entered each movable small winning opening 22. indicate. The detection member will be described later. The numbers are just examples and may be displayed in Chinese characters or the number of stars. The image display device 60 may display a design or the like when the movable small winning opening 22 is not open. As shown in FIG. 7, in the image display device 60, a frame member 61 is formed so as to surround the lower side surface and the front surface of the tulip of the movable small winning opening 22, and the image display device 60 is formed in front of the frame member 61. It is provided. As shown in FIG. 7A, the frame member 61 is provided with a mounting piece 61a in a substantially U-shaped cross section, and the mounting piece 61a is a mounting hole for mounting the base member 30d of the movable small winning opening 22. It is attached by the screwing member 61b using 34. The image display device 60 is electrically connected to a control circuit arranged on the back side of the pachinko gaming machine 200 via a frame member 61. The control circuit counts the winning game balls and controls the winning balls. Based on the signal from the control circuit, the image display device 60 may appropriately select and display an image, or display the count of the game balls that have entered the movable small winning opening 22 on the image display device 60. it can. As a counting method, as usual, a magnetic force type detection member may be provided on the back side of the movable small winning opening 22, but for example, as shown in FIG. 7B, the optical sensor 50 is used as an image display device 60. It may be provided in. The number of movements of the tulip blades may be counted by providing the optical sensor 50 at a position corresponding to the opening of the tulip blades and providing the reflector 51 at a position facing the tulip blades. That is, the tulip wings repeatedly open and close each time the game ball enters, so when the tulip wings are present (the tulip wings are open) and when they are not present (the tulip wings are closed). The number of game balls that have entered the tulip can be counted by counting the number of game balls that have entered the tulip. This information is sent to the control circuit described above and sent to the image display device 60. The movable small winning openings 22 are arranged so as to be parallel to each other in the horizontal direction, one in the center and three in the lower direction.

The big winning opening 30 is an openable type, and in the case of a big hit, the big winning opening 30 is maintained in an open state for a predetermined time. In the present embodiment, two large winning openings 30 are provided in parallel below the game area. By providing two big winning openings 30, it is possible to provide two stages for the big hit, depending on whether only one is opened or two are opened in the case of a big hit.

The pendulum type work-in-process 40 is arranged above the movable small winning opening 22 arranged substantially in the center. As shown in FIG. 8A, the pendulum type work-in-process 40 has an upper surface winning opening 42a, and the game ball entered in the upper surface winning opening 42a flows on the back surface to open the movable winning opening 22a. Further, the pendulum type work-in-process 40 has a first ball receiving surface 42b and a second ball receiving surface 42c on the left and right sides, and a game ball is placed on the first ball receiving surface 42b and the second ball receiving surface 42c. When placed, as shown in FIG. 8B, it can move like a pendulum depending on the weight of the game ball, and can change the falling direction of the game ball. Further, the winning holes 44 formed on the back surface side of the pendulum are won according to the swing angle of the pendulum. When the ball enters the winning hole 44 on the left side, the movable small winning opening 22b on the left side opens, and when the ball enters the winning hole 44 on the right side, the movable winning opening 22c on the right side opens.

Further, a plurality of wind turbines 16 are horizontally provided at a portion where so-called heaven nails are arranged. This windmill 16 replaces the conventional heaven nail. By arranging the wind turbine 16, when the game ball passes through the wind turbine 16 arranged in the vertical direction, the rotation of the game ball is suppressed and the vibration in the lateral direction is also suppressed, so that the momentum of the game ball is suppressed. Will fall, making it easier to fall vertically.

Further, as shown in FIG. 2, a plurality of eccentric rotating wind turbines 17 are continuously arranged in a row on the left and right sides of the game area 10. As shown in FIG. 9, the uneven rotation wind turbine 17 has different thicknesses of the blades 17a between the side 17b attached to the game plate and the disk side 17c, and the thickness gradually increases from one side to the other. It is formed to be thick. In FIG. 9, it is formed so as to gradually increase in thickness from the side 17b attached to the game plate 100 toward the disk side 17c, but it becomes thicker from the disk side 17c toward the side 17b attached to the game plate 100. It may be formed so as to become. As shown in FIG. 9A, the blades 17a have one surface 17d formed on a flat surface and the opposite surface 17e formed of a concave curved surface, and the surfaces on the same side in the direction of rotation with respect to all the blades 17a. Is formed by a concave curved surface. In FIG. 9A, when rotating clockwise, that is, rotating in the direction of the arrow on the upper side, the surface on the rotating side is formed into a concave curved surface. By using such an unbalanced rotating wind turbine 17, the falling direction of the game ball that hits the wind turbine can be biased. In the case of FIG. 9A, since the concave curved surface side is largely repelled, the probability of falling to the A side is high. As shown in FIG. 9B, such an eccentric rotating wind turbine 17 is also manufactured with a concave curved surface formed on the opposite surface to the eccentric rotating wind turbine 17 of FIG. 9A, and has a high probability of falling to the side of B. An eccentric rotating wind turbine 17 is also prepared. The eccentric rotating wind turbines 17 produced in this way are arranged in a row so as to be vertically arranged three by three on each of the left and right sides with respect to the game board, and fall to the side of A in one row. All the eccentric wind turbines 17 (FIG. 9A) having a high probability are attached, and all the eccentric wind turbines 17 (FIG. 9B) having a high probability of falling to the side of B are attached to the other row. The eccentric rotating wind turbine 17 is attached by forming a pin produced by insert molding in advance on the game plate 100, inserting the eccentric rotating wind turbine 17 into the pin, and holding the upper portion of the pin with an E ring. Therefore, the eccentric rotating wind turbine 17 can be easily removed. Therefore, when the pachinko machine is tilted and the game ball is biased in the falling direction of the entire pachinko machine, the falling direction can be adjusted by exchanging a part of the eccentric rotating wind turbine 17 on the left and right.

The out opening 70 is for collecting out balls that have not entered the small winning opening 20 and the large winning opening 30.

As shown in FIG. 10, the game board 100 produced as described above is attached so as to be fitted into the game board frame 110 for mounting the game board 100 of the pachinko game machine 200.

Further, as shown in FIGS. 10 and 11, a support portion 116 for supporting the game plate formed of an elastic body made of resin, silicon, rubber, or the like may be provided in the lower corner on the side opposite to the fitting side. good. By adopting such a configuration, since the game plate 100 can be attached while pressing the support portion 116 made of an elastic body, it is possible to make it difficult to move in the front direction and the back direction of the game plate 100. Further, as shown in FIG. 10, a concave portion 117a and a convex portion 117b are provided on the lower end of the game plate 100 and the elastic body 115, and the game board is moved to the left and right by fitting them so as to fit each other. Can be reduced.

The pachinko gaming machine 200 configured as described above is used as follows. As shown in FIG. 1, the pachinko gaming machine 200 includes a game area 10 located at a substantially central portion of the front surface, and a launch handle 120 rotatably provided on the right side of the lower front surface in conjunction with a ball launcher. The launch handle 120 launches a game ball into the game area of the game board 100.

The game ball launched by the launch handle 120 is sent into the game area 10 and falls in the game area 10 while being repelled by the obstacle protrusion 15 and the like. If a ball is directly entered into the fixed small prize opening 21 during the fall, a predetermined number of balls will be paid out as a prize ball. Further, when the ball is entered into the upper surface winning opening 42a by the pendulum type work in process 40, the central movable small winning opening 22a is opened, and when the ball is entered into the winning hole 44 on the left side, the movable small on the left side is opened. When the winning opening 22b opens and the ball enters the winning hole 44 on the right side, the movable small winning opening 22c on the right side opens. Also, when the ball enters the central movable small winning opening 22d, the central movable small winning opening 22a will open. When a ball is entered into the movable small winning opening 22 opened in this way, a predetermined number of balls are paid out as prize balls, and the count of the game balls entered in the image display device 60 is displayed. Further, when the numbers of the image display devices (22a to 22c) of the three movable small winning openings 22 on the lower side are aligned, and when the numbers are so-called doublets, the lottery starts. If the result of the lottery is a big hit, one or two big prize openings 30 will be opened.
