Among these, the game ball that has flowed down the general winning opening 22B side and lost the winning opportunity flows down to any of the following flow paths A to D.

  The game ball that has flowed down to the left side of the general winning opening 22B flows down the flow path A. And it falls on the guide rail 2 provided below the game board 1. Since the guide rail 2 is inclined so as to descend from the lower side of the general winning opening 22B toward the out port 32, the dropped game ball is guided to the upper surface of the guide rail 2 and flows down to the out port 32, and the out It is discharged from the mouth 32.

  The game ball that has flowed down between the general winning opening 22B and the windmill 40 flows down the flow path B (the ball passage detection flow path 45). Then, while abutting against the right side surface of the general winning opening 22 </ b> B and the left side surface of the shaft portion 402 of the windmill 40, it flows down between the two.

  The general winning opening 22B and the ball passage detection sensor 41 are connected by a rolling surface 46. The rolling surface 46 covers the upper surface of the ball passage detection sensor 41, and further inclines and extends so as to descend from the ball passage detection sensor 41 toward the guide rail 2.

  In the present embodiment, the ball passage detection sensor 41 is provided on the back surface side of the rolling surface 46. However, the ball passage detection sensor 41 may be a flat proximity sensor 41 that is extremely thin so as not to block the flow path of the game ball. For example, it may be provided on the upper surface of the rolling surface 46. Further, the ball passage detection sensor 41 may be provided between the shaft portion 402 of the windmill 40 and the rolling surface 46 and on the back surface side of the base 61 of the ball passage detection unit 25.

  The game ball that has flowed down between the general winning opening 22 </ b> B and the shaft portion 402 of the windmill 40 passes over the ball passage detection sensor 41 while being guided by the rolling surface 46. Then, it is guided by the rolling surface 46 extending so as to descend from the ball passage detection sensor 41 and falls onto the guide rail 2. The dropped game ball is guided to the upper surface of the guide rail 2, flows down to the out port 32, and is discharged from the out port 32.

  Thus, by providing the ball passage detection sensor 41 on the rolling surface 46 and providing the windmill 40 at a position facing the rolling surface 46, the game ball flowing down the game area 3 is suitable for the ball passage detection sensor 41. The game ball passing on the ball passage detection sensor 41 can be detected with high accuracy.

  Note that the rolling surface 46 is a surface (detection surface) 461 on which the ball passage detection sensor 41 is provided, and a front and rear surface (a surface 460 connecting the general winning opening 22B and the ball passage detection sensor 41, and a ball surface). The inclination is gentler than the surface 462) extending from the passage detection sensor 41 toward the guide rail 2. By configuring the inclination of the rolling surface 46 in this way, the game ball that has flowed down the game area 3 and between the general winning port 22B and the windmill 40 can be suitably brought close to the ball passage detection sensor 41. it can. Further, since the game ball that has passed through the detection surface 461 can quickly flow down in the direction of the guide rail 2, the game ball that passes through the detection area 410 (FIG. 7) of the ball passage detection sensor 41 and the detection area 410. Thus, it is possible to prevent the ball from hitting the game ball and accurately detect the game ball passing on the ball passage detection sensor 41.

  The game ball that has flowed to the right side of the windmill 40 through the right side of the general winning opening 22B flows down the flow path C. Then, it flows down the right side of the shaft portion 402 and falls onto the guide rail 2. The dropped game ball is guided to the upper surface of the guide rail 2, flows down to the out port 32, and is discharged from the out port 32.

  The game ball that abuts on the shaft portion 402 of the windmill 40 and rolls further to the right flows down the flow path D. Then, it flows down toward the special fluctuation winning device 26 provided in the ball passage detection unit 25. At this time, if the special variable winning device 26 is in the open state, the game ball has a possibility of winning the special variable winning device 26. On the other hand, when the special variable winning device 26 is closed, the game ball falls on the guide rail 2 without winning the special variable winning device 26 and is guided to the upper surface of the guide rail 2 and flows down to the out port 32. And discharged from the outlet 32.

  In this way, the game ball flowing down the flow path D has a possibility of winning a prize to the special variation winning device 26. On the other hand, the game balls flowing down the flow paths A to C have lost the winning opportunity to any winning opening. In this embodiment, the ball passage detection sensor 41 is provided in the flow path B (the ball passage detection flow path 45), and the passage of the game ball that has lost the winning opportunity is detected. Then, when the passage of the game ball is detected by the ball passage detection sensor 41, for example, a privilege that does not cause a disadvantage on the game hall side is given to the player, and the interest of the game is improved.

  Note that the game ball flowing down the ball passage detection flow path 45 loses a chance to win any prize opening. Therefore, when the passage of the game ball is detected by the ball passage detection sensor 41, the player By giving a privilege that is not disadvantageous to the game hall side to the bonus given to the game hall, even if a game ball is detected by the ball passage detection sensor 41, there is no loss of the game hall. Therefore, the game hall does not need to strictly manage the adjustment of the nail for guiding the game ball to the detection area 410 of the ball passage detection sensor 41.

It is located behind the hole 630 so that the player can visually recognize it from the front.

  The lens member 70 has a sensor housing portion 74 and a rolling surface 46 protruding forward and a windmill mounting portion 73 protruding rearward with respect to the grass-like plate member 71.

  The plate member 71 is attached to the attacker base 60 to decorate the left and right sides of the special variable winning device 26. Display windows 700 and 701 are formed on the front surface of the plate member 71 at positions corresponding to the special-purpose display 30 and the general-purpose display 31, respectively. In the display windows 700 and 701, when the lens member 70 is attached to the attacker base 60, the light transmitting hole 630 is located on the back surface. Therefore, the player can visually recognize the special-purpose display 30 and the general-purpose display 31 through the display windows 700 and 701 from the front of the gaming machine.

  On the left and right upper sides of the lens member 70, there are provided winning hole storing portions 72B and 72D made of cylindrical side walls slightly larger than the outer peripheries of the general winning holes 22B and 22D. In the winning opening storing portions 72B and 72D, decorative members 73B and 73D are attached to the front side opening portion. The decorative members 73B and 73D include a disc member 730B or 730D and three engaging members 731B or 731D that stand upright rearward from the disc members 730B and 730D. Then, the decoration members 73B and 73D are attached to the winning opening storing portions 72B and 72D by inserting the engaging members 731B or 731D from the front of the winning opening storing portions 72B and 72D and engaging them.

  A rolling surface 46 extends to the lower right from the winning opening storing portion 72B. The rolling surface 46 has a predetermined thickness, and a sensor storage portion 74 is formed in the middle. The sensor storage portion 74 stores the ball passage detection sensor 41 when the lens member 70 is attached to the attacker base 60.

  A substantially cylindrical windmill mounting portion 75 made of a transparent resin is provided on the right side of the winning opening storing portion 72B and at the upper right position of the sensor storing portion 74. The windmill mounting portion 75 is accommodated in the receiving groove 64 when the lens member 70 is mounted on the attacker base 60. A through hole 750 is provided in the center of the front surface of the windmill mounting portion 75. The through hole 750 is formed of a circle slightly larger than the outer periphery of the shaft attachment portion 400 of the windmill 40, and the shaft attachment portion 400 is inserted when the windmill 40 is attached to the windmill attachment portion 75.

  The windmill 40 includes a disk portion 401 provided on the front surface, a cylindrical shaft portion 402 provided rearward from the center of the back surface of the disk portion 401, and a cylindrical shaft mounting portion provided in the cylinder of the shaft portion 402. 400. The windmill 40 is formed of a transparent resin, and the LEDs 81A to 81F provided on the back side of the windmill 40 can be viewed from the front of the gaming machine. In addition, the windmill 40 does not need to form the whole with transparent resin, and should just be able to visually recognize LED81A-81F from the front. The configuration of the windmill 40 will be described in detail with reference to FIGS. 6 and 7.

  The windmill 40 is provided with a shaft hole 403 at the center. The shaft hole 403 penetrates from the center of the disk portion 401 to the shaft mounting portion 400. The rotating shaft 47 is inserted through the shaft hole 403, and is further inserted through the through hole 750 and the bearing 640 via the bush 76. And by attaching an E-ring to an E-ring attachment part 470 provided at the tip of the rotating shaft 47 on the back surface side of the bearing 640, the windmill 40 is fixed in a non-detachable manner in the front-rear direction.

  The windmill substrate 80 is provided with six LEDs (light emitters) 81 </ b> A to 81 </ b> F at equal intervals along the substantially disk-shaped circumference. LED81A-81F is arrange | positioned in the position along the outer periphery of the axial part 402 of the windmill 40, when the ball | bowl passage detection unit 25 is comprised integrally. An insertion hole 82 is formed in the approximate center of the windmill substrate 80. The insertion hole 82 allows the bearing 640 protruding rearward from the back surface of the attacker base 60 to pass therethrough.

  The back box 90 is provided with a substrate accommodating portion 91 that can accommodate the windmill substrate 80. And the windmill board | substrate 80 is accommodated in the board | substrate accommodating part 91, and it is attached to the back of the receiving groove 64. FIG. As a result, the back box 90 attaches the windmill substrate 80 behind the receiving groove 64.

  As described above, the light transmitting hole 641 is provided in the concave surface of the receiving groove 64 at a position corresponding to the LEDs 81A to 81F. Moreover, the windmill attachment part 75 accommodated in the front surface of the receiving groove 64 is comprised with transparent resin. Therefore, the LEDs 81A to 81F can be visually recognized from the front of the game board 1 along the outer periphery of the shaft portion 402 of the windmill 40 by emitting light.

  Further, an insertion hole 92 through which a bearing 640 that protrudes rearward from the back surface of the attacker base 60 is inserted is formed in the approximate center of the concave surface of the substrate housing portion 91.

  The ball passage detection unit 25 is configured by attaching each of the above members in the front-rear direction.

  FIG. 5 is an explanatory view of the vicinity of the windmill 40 according to the embodiment of the present invention, and shows a game ball flowing down the ball passage detection flow path 45.

  FIG. 5A is a front view of the vicinity of the windmill 40 and the ball passage detection sensor 41. FIG. 5B is a cross-sectional view taken along the line AA in FIG.

  A rotation shaft 47 is inserted through the shaft mounting portion 400 provided at the center of the windmill 40 from the front to the rear. The rotating shaft 47 is further inserted into the lens member 70, the attacker base 60, the windmill substrate 80, and the back box 90 in a state of being inserted into the shaft mounting portion 400 of the windmill 40, and the windmill 40 is attached to these members.

  The attacker base 60 is provided with a sensor fixing portion 600 for fixing the ball passage detection sensor 41. The ball passage detection sensor 41 is fitted and fixed to the sensor fixing portion 600, and the front surface and the upper surface are covered with the rolling surface 46 and fixed. The ball passage detection sensor 41 detects a game ball that passes between the rotation shaft 47 and the ball passage detection sensor 41 (the ball passage detection flow path 45).

  FIG. 6 is a rear perspective view of the windmill 40 according to the embodiment of the present invention.

  The disk portion 401 of the windmill 40 is provided with a substantially cylindrical shaft portion 402 at the center. In addition, a substantially cylindrical shaft mounting portion 400 having a diameter smaller than that of the shaft portion 402 is provided in the cylinder of the shaft portion 402 so as to extend rearward from the shaft portion 402.

  Three standing walls 404 are provided on the outer peripheral surface of the shaft portion 402 at equal intervals toward the outside. The number of standing walls 404 is not limited to three, and the standing walls 404 may not be provided at equal intervals with respect to the outer peripheral surface of the shaft portion 402.

  The height of the standing wall 404 is configured to be small. Therefore, even if the game ball passes in the vicinity of the shaft portion 402, the game ball is unlikely to come into contact with the side surface of the standing wall 404. Therefore, the urging | biasing to the rotation direction of the windmill 40 by a game ball contact | abutting on the side surface of the standing wall 404 is few.

  However, as in the case of a conventional windmill, when the standing wall has a height up to the circumference of the disk portion, for example, the game ball flowing down the rolling surface 46 is blocked by the standing wall from the flow path and passes through the ball. There is a possibility that a plurality of game balls stay in the detection flow path 45 and a ball stop occurs.

  In addition, the game ball that has flowed down to the right side of the shaft portion (the side on which the special variation winning device 26 is provided) abuts on the standing wall, and urges the standing wall downward on the right side of the shaft portion. There is a possibility that the game ball flowing down the left side (the ball passage detection flow path 45) is bounced up by the upright wall biased upward, and the flow into the ball passage detection flow path 45 may be prevented.

  When the game ball is bounced up by the standing wall on the detection surface 461, the game ball once detected by the ball passage detection sensor 41 flows down to the detection surface 461 again after being bounced up. Then, the passage is detected again by the ball passage detection sensor 41. Thus, it is not preferable that one game ball travels on the detection surface 461 and is detected by the ball passage detection sensor 41 a plurality of times because the detection accuracy of the game ball is lowered.

  On the other hand, since the standing wall 404 of the present embodiment is sufficiently small with respect to the diameter of the game ball, the efficiency of the falling force of the game ball acting to rotate the windmill 40 is remarkably low. The efficiency of the standing wall 404 acting on the game ball due to the rotational force of 40 is also extremely low. Therefore, it is possible to prevent the ball of the game ball from stopping and the game ball from jumping up by the standing wall 404. Note that the specific height of the standing wall 404 will be described with reference to FIG.

  FIG. 7 is a configuration diagram of the windmill 40 according to the embodiment of this invention.

  FIG. 7A is a configuration diagram showing the distance between the outer peripheral surface of the shaft portion 402 and the rolling surface 46.

  A rolling surface 46 that slopes from the upper left to the lower right is provided at the lower left of the windmill 40. A ball passage detection sensor 41 is provided at the center of the rolling surface 46. The game ball flowing down from the surface 460 passes through the detection surface 461 and flows down to the surface 462.

  The shaft portion 402 and the rolling surface 46 are separated so that one game ball can pass through. Specifically, the space between the outer peripheral surface of the shaft portion 402 and the detection surface 461 is separated by a gap (for example, 12.8 mm) slightly larger than the diameter of the game ball (about 11.0 mm) to the game board 1. Arrange. In addition, when the shaft portion 402 and the rolling surface 46 are not sufficiently separated due to the restriction of the arrangement, the game ball is interposed between the shaft portion 402 and the rolling surface 46 by using the shaft portion 402 having a small diameter. Spacing slightly larger than the diameter of

  Thus, the flow path of the game ball that has flowed down to the left side of the windmill 40 is regulated relatively gently by the rolling surface 46 to guide the game ball to the position where the ball passage detection sensor 41 is provided, By setting the distance between the shaft portion 402 and the rolling surface 46 so that one game ball can pass, a new gate is provided in the game area 3 for detecting the game ball, or a nail is implanted. Since it is not necessary to provide a flow path for the game ball, the degree of freedom of arrangement of other components (for example, the image display device 10, the start ports 24A, 24B, etc.) provided on the game board 1 is not reduced. , It is possible to detect passing game balls one by one.

  FIG. 7B is a configuration diagram showing the distance between the standing wall 404 and the rolling surface 46.

  The standing wall 404 and the rolling surface 46 are separated so as to be larger than the diameter of the game ball. Specifically, the height of the standing wall 404 is configured such that the distance between the tip of the standing wall 404 and the detection surface 461 is larger than the diameter of the game ball (about 11.0 mm). For example, when the distance between the outer peripheral surface of the shaft portion 402 and the detection surface 461 is 12.8 mm, the height of the standing wall 404 is set to 0.5 mm. In this case, the distance between the tip of the standing wall 404 and the detection surface 461 is 12.3 mm, which is larger than the diameter of the game ball (about 11.0 mm).

  Thus, by configuring the height of the standing wall 404 so that the distance between the tip of the standing wall 404 and the rolling surface 46 is larger than the diameter of the game ball, the game ball passes through the ball passage detection flow path 45. Since it can pass without being blocked by the standing wall 404, it is possible to prevent the ball from stopping. In addition, the game ball does not jump up in the ball passage detection flow path 45 when the game ball comes into contact with the standing wall 404 on the right side of the shaft portion 402.

  FIG. 7C is a configuration diagram showing a detection region 410 of the ball passage detection sensor 41.

  The ball passage detection sensor 41 used in the present embodiment sets a range of a radius of 5 mm from the upper surface of the ball passage detection sensor 41 as a detection region 410. When a game ball passes through the detection area 410, the game ball is detected by the ball passage detection sensor 41. The ball passage detection sensor 41 outputs a detection signal to the display control device 150 when the passage of the game ball is detected.

  The upper surface of the ball passage detection sensor 41 is covered with a plate-like resin constituting the detection surface 461. The detection surface 461 that covers the upper surface of the ball passage detection sensor 41 is configured to have a small thickness (for example, 1.0 to 1.5 mm). As a result, the area above the ball passage detection sensor 41 and having a radius of about several millimeters from the detection surface 461 becomes the detection area 410 of the game ball. That is, when the game ball passes over the detection surface 461, the game ball always passes through the detection area 410, and thus is always detected by the ball passage detection sensor 41.

  As described above, the detection area 410 of the ball passage detection sensor 41 is provided between the outer peripheral surface of the shaft portion 402 and the rolling surface 46, so that the game ball passing between the windmill 40 and the rolling surface 46 can be reliably obtained. Can be detected one by one.

  FIG. 8 is an explanatory diagram of the LEDs 81A to 81F according to the embodiment of the present invention.

  FIG. 8A is a layout diagram of the LEDs 81A to 81F provided on the windmill substrate 80. FIG.

  The LEDs 81 </ b> A to 81 </ b> F are arranged at equal intervals around an insertion hole 82 provided in the approximate center of the windmill substrate 80. The insertion hole 82 is provided at a position corresponding to the shaft portion 402 of the windmill 40. That is, the LEDs 81 </ b> A to 81 </ b> F are arranged at equal intervals around the shaft portion 402 when the game board 1 is viewed from the front.

  Specifically, the LED 81A is directly above the shaft portion 402, the LED 81B is above the shaft portion 402, the LED 81C is below the shaft portion 402, the LED 81D is directly below the shaft portion 402, and the LED 81E is below the shaft portion 402. The LED 81F is disposed on the upper left of the shaft 402.

  FIG. 8B is a timing chart of lighting of the LEDs 81A to 81F.

  The ball passage detection sensor 41 outputs a detection signal to the display control device 150 when the passage of the game ball is detected. When the display control device 150 receives the detection signal from the ball passage detection sensor 41, the display control device 150 outputs a decoration control command signal related to the LEDs 81A to 81F to the decoration control device 300.

  When the decoration control device 300 receives the decoration control command signal from the display control device 150, the decoration control device 300 lights the LED 81A for a certain period of time. Then, when the fixed time has elapsed and the LED 81A is turned off, the LED 81B is turned on after the fixed time has elapsed. Then, when the fixed time has elapsed and the LED 81B is turned off, the LED 81C is turned on after the fixed time has elapsed. Thereafter, similarly, the decoration control device 300 controls the LED 81C to be turned off → the LED 81D is turned on → the LED 81D is turned off → the LED 81E is turned on → the LED 81E is turned off → the LED 81F is turned on → the LED 81F is turned off. Then, after a certain period of time has elapsed since the LED 81F is turned off, the LED 81A is turned on again, and then the LEDs 81B to 81F are sequentially turned on.

  By controlling each LED in this way, the light spot makes two rounds around the shaft portion 402 of the windmill 40 with the game ball passing through the ball passage detection sensor 41 as a trigger. This makes it appear that the windmill 40 is rotating because the game ball has passed through the ball passage detection sensor 41, and it can be easily confirmed that the game ball has passed in the vicinity of the windmill 40. Moreover, it replaces with the windmill 40 which is hard to rotate because the standing wall 404 is low, and LED81A-81F improves the interest of a game.

  The embodiment disclosed this time is illustrative in all points and is not restrictive. The scope of the present invention is defined not by the above description of the invention but by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.
