Description

  The present invention relates to a gaming machine to which a gaming board including a center accessory is attached.

  In general, a pachinko machine, which is a type of gaming machine, includes a plurality of winning devices in the gaming area of the gaming board. When a game ball wins these winning devices, the player is given an opportunity to acquire a large number of prize balls. However, in recent pachinko machines, the display area of the symbol display device tends to increase in size, so that the frame-shaped center accessory provided with an opening that exposes the display area also tends to increase in size (for example, Patent Document 1). In addition, in recent years, with the transition to gaming state such as big hit gaming state, variation time shortened state (so-called “short time”), probability variation state (so-called “probability variation”), Many gaming machines that play games by launching a game ball (so-called right-handed) aiming at a tulip (so-called “electric chew”), a prize-winning device or the like have been proposed.

Japanese Patent Laying-Open No. 2011-104291 (FIGS. 1, 2, etc.)

  By the way, generally, a structure for fixing to a game board called a “base plate” is provided on the outer periphery of the center accessory. By inserting a screw into a screw insertion hole that penetrates the base plate and screwing the tip of the inserted screw into the game board, the center accessory is mounted in the game area.

  However, as described above, the center accessory tends to increase in size in recent years, and accordingly, the ratio of the game area to the game board tends to decrease, so it becomes difficult to attach the base plate to the game board. There is a case. More specifically, it is preferable to increase the size of the base plate and increase the contact area between the base plate and the game board surface in order to firmly fix the center role to the game board. However, if the base plate is increased in size, the game area becomes smaller due to the presence of the base plate, so at present, the base plate must be formed small. In this case, since the strength of the base plate, and hence the fixing strength of the center feature, is reduced, the strength is increased by forming the base plate thickly to support the center feature that has become heavy due to the increase in size. It is necessary to ensure.

  However, if the base plate is formed thick, the amount of protrusion of the base plate from the game board surface to the near side becomes large. In particular, when the game ball is hit to the right, the game ball is launched at a high speed by turning the operation handle to the right, so that the firing speed is very high. Therefore, there is a possibility that the game ball launched into the game area may collide with a strong momentum against the base plate of the entrance part of the game ball passing path on the upper side of the center object, so the base plate may be damaged, There is a possibility that the game ball may be thrown up to the near side and adversely affect the movement of the game ball. In addition, the speed of the game ball flowing through the game ball passage route may be reduced.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a gaming machine capable of preventing adverse effects on the movement of a game ball while preventing a decrease in strength of the base plate.

  In order to solve the above-mentioned problems, the invention described in claim 1 (means 1) includes a substantially rectangular plate-like plate member having a game board surface, and a game area that is laid on the game board surface and allows a game ball to flow down. And a center board mounted on a game area of the game board surface, and a base plate that contacts the game board surface is formed on an outer peripheral portion of the center role. A gaming ball passing path through which a gaming ball launched by a launching device passes in an area between the rail and the center accessory at the upper part of the gaming area, and the base plate is A center plate body formed on at least an entrance portion of the game ball passage route at an outer peripheral portion of the center accessory, a back surface side contacting the game board surface, and an upstream side of the game ball passage route, and on the game board surface Lean against A first tapered portion having a first inclined surface, and a second tapered portion having a second inclined surface that is located on the downstream side of the game ball passage path relative to the first tapered portion and is inclined with respect to the game board surface. The connecting portion between the second inclined surface and the game board surface is more gently continuous than the connecting portion between the first inclined surface and the game board surface, and the second tapered portion is cut in the vertical direction. The length of the oblique side that appears is set longer than the length of the oblique side that appears when the first tapered portion is cut in the vertical direction, and the outer peripheral edge of the second tapered portion is curved along the game ball passage path. The gist of the gaming machine is characterized by its shape.

  Therefore, according to the first aspect of the present invention, the connecting portion between the second inclined surface and the game board surface is continued more gently than the connecting portion between the first inclined surface and the game board surface. As a result, since the movement of the game ball passing on the second inclined surface becomes smooth, it is possible to prevent adverse effects on the movement of the game ball.

  In addition, since the second taper portion has a longer hypotenuse than the first taper portion, the thin region becomes larger, so that the strength is lower than that of the first taper portion. However, since the second taper portion is located on the downstream side of the game ball passage path with respect to the first taper portion, the possibility that the game ball collides with the first taper portion becomes smaller. Specifically, the game ball can collide with the second taper portion in the state where the momentum of the game ball remains strong, that is, the momentum of the game ball does not decrease due to collision with other members. The sex becomes smaller. From the above, even if the base plate includes the second tapered portion having low strength, it is possible to prevent the strength of the base plate from being lowered. In addition, since the outer peripheral edge of the second taper portion has a curved shape along the game ball passage path, the impact at the time of the collision of the game ball is less likely to concentrate, so the second taper associated with the impact at the time of the collision of the game ball Damage to the part can be prevented.

  Note that the plate member may be formed of a colored material or may be formed of a colorless and transparent material. If the plate member is made of a colored material, the plate member can be used as a decorative member. On the other hand, if the plate member is formed of a colorless and transparent resin material, the display screen of the symbol display device can be visually recognized through the plate member when the symbol display device is arranged on the back side of the plate member.

  Moreover, although it does not specifically limit as a material which forms a base plate, For example, a resin material and a metal material can be mentioned. If the base plate is formed by injection molding of a resin material, the base plate can be easily formed. Preferred examples of the resin material forming the base plate include ABS resin, PP resin (polypropylene resin), PC / ABS resin, PC resin (polycarbonate resin), PMMA resin (acrylic resin), POM resin (polyacetal resin), and PBT. Examples thereof include a resin (polybutylene terephthalate resin) and a PET resin (polyethylene terephthalate resin). Alternatively, a fluorine resin material such as polytetrafluoroethylene (PTFE) may be used. Furthermore, examples of the metal material forming the base plate include aluminum and iron. The base plate may be formed integrally with the center accessory, or may be formed separately from the center accessory.

  The invention according to claim 2 (means 2) is that in claim 1, the base plate is located between the first taper portion and the second taper portion, and is inclined with respect to the game board surface. A third taper portion having three inclined surfaces, wherein a connection portion between the third inclined surface and the game board surface continues more gently than a connection portion between the first inclined surface and the game board surface; The second inclined surface is continuous at a steeper angle than the connecting portion of the game board surface, and the third inclined surface gradually becomes gentle as it goes from the first inclined surface side to the second inclined surface side. The gist.

  Therefore, according to the second aspect of the present invention, the third inclined surface of the third taper portion gradually gradually increases from the first inclined surface side of the first taper portion toward the second inclined surface side of the second taper portion. Therefore, the first inclined surface and the second inclined surface can be gently connected via the third inclined surface. As a result, the movement of the game ball passing on the base plate becomes even smoother, so that it is possible to more reliably prevent adverse effects on the movement of the game ball.

  The invention according to claim 3 (means 3) is the invention according to claim 1 or 2, wherein the base plate is provided with a screw insertion hole through which a screw is inserted, and the screw insertion hole is formed in the base plate main body. The gist of the invention is that the screw, which is disposed in the vicinity of the tapered portion and is inserted through the screw insertion hole, is screwed to the game board.

  Therefore, according to the third aspect of the present invention, since the screw insertion hole is provided in the base plate main body having higher strength than the taper portion, even if the screw insertion hole is provided, the strength reduction of the base plate is prevented. be able to. Further, the screw insertion hole is disposed in the vicinity of the first taper portion that is less likely to pass the game ball than the second taper portion. As a result, the possibility that the movement of the game ball is disturbed by the screw inserted through the screw insertion hole is reduced.

  The invention according to claim 4 (means 4) is the game board according to any one of claims 1 to 3, wherein the game board is implanted in the game area, and the direction of the game ball flowing down in the game area is set. A plurality of game nails to be changed are provided, and the plurality of game nails are implanted in a region on the side of the first taper portion and in the vicinity of the edge of the first taper portion, and the game is fired by a launching device. The gist includes an anti-collision nail that prevents the ball from directly colliding with the first inclined surface.

  Therefore, according to the fourth aspect of the present invention, the collision preventing nail is implanted in the region near the edge of the first taper portion on the side of the first taper portion. The ball can be prevented from colliding with a strong momentum. Moreover, since the momentum of the game ball launched by the launching device is weakened by colliding with the collision prevention nail, it is possible to reduce the burden on the base plate when the game ball collides with the base plate. Therefore, it is possible to prevent the base plate from being damaged due to the impact at the time of collision, and to reduce the adverse effect on the movement of the game ball. Here, “the game ball directly collides with the first inclined surface” means that the momentum of the game ball remains strong, that is, the momentum of the game ball does not decrease due to collision with other members. It means that a game ball collides with the first inclined surface (first taper portion) in the state.

  The invention described in claim 5 (means 5) includes a substantially rectangular plate-like plate member having a game board surface, an arc-shaped rail laid on the game board surface and defining a game area in which a game ball can flow down, A game board having a center accessory attached to the game area of the game board surface is attached, and a start winning device that allows a symbol change in response to the winning of the game ball in the game area, and the game ball can win A prize-winning device that can be switched to an open state, and a base plate that is in contact with the surface of the game board is formed on an outer peripheral portion of the prize-winning device. A grand prize winning path for guiding the launched game ball to the grand prize winning device is configured, and the base plate is formed at least at a terminal portion of the big winning prize winning route at an outer peripheral portion of the big prize winning device, and a back side is the game. The base plate body in contact with the board surface A first taper part having a first inclined surface that is located upstream of the prize winning path and is inclined with respect to the game board surface, and is located downstream of the first prize winning path from the first taper part. A second tapered portion having a second inclined surface inclined with respect to the game board surface, and a connection portion between the second inclined surface and the game board surface is a connection between the first inclined surface and the game board surface. The length of the hypotenuse that appears when the second taper portion is cut in the vertical direction is set longer than the hypotenuse length that appears when the first taper portion is cut in the vertical direction. The gist of the gaming machine is characterized in that an outer peripheral edge of the second tapered portion has a curved shape along the path of the special winning award.

  Therefore, according to the fifth aspect of the present invention, the connecting portion between the second inclined surface and the game board surface is continued more gently than the connecting portion between the first inclined surface and the game board surface. As a result, since the movement of the game ball passing on the second inclined surface becomes smooth, it is possible to prevent adverse effects on the movement of the game ball.

  In addition, since the second taper portion has a longer hypotenuse than the first taper portion, the thin region becomes larger, so that the strength is lower than that of the first taper portion. However, since the second taper portion is located downstream of the first taper portion in the big winning opening route, the possibility that the game ball collides with the first taper portion is smaller than that of the first taper portion. From the above, even if the base plate includes the second tapered portion having low strength, it is possible to prevent the strength of the base plate from being lowered. In addition, since the outer peripheral edge of the second taper portion has a curved shape along the path of the big prize opening, it becomes difficult for the impact at the time of the collision of the game ball to concentrate, so the second taper associated with the impact at the time of the collision of the game ball Damage to the part can be prevented.

  As described above in detail, according to the first to fifth aspects of the present invention, it is possible to provide a gaming machine that can prevent adverse effects on the movement of the game ball while preventing the strength of the base plate from being lowered. . In particular, according to the second aspect of the present invention, since the movement of the game ball passing on the base plate becomes smoother, it is possible to more reliably prevent adverse effects on the movement of the game ball.

The third inclined surface 64 a is an inclined surface that connects the first inclined surface 62 a of the first tapered portion 62 and the second inclined surface 63 a of the second tapered portion 63. The length of the hypotenuse 64b (see FIG. 9) that appears when the third taper portion 64 is cut in the vertical direction gradually increases from the first taper portion 62 side to the second taper portion 63 side. The length of the hypotenuse 64b in the present embodiment is set to 2.0 mm at the connection portion with the first taper portion 62, and is set to 5.0 mm at the connection portion with the second taper portion 63. Further, the length of the side 64c (see FIG. 9) perpendicular to the game board surface 13a that appears when the third taper portion 64 is cut in the vertical direction, that is, the thickness of the thinnest portion of the third taper portion 64. This is set to 0.5 mm in the present embodiment. The boundary portion between the third inclined surface 64a where the oblique side 64b appears and the tip surface where the side 64c appears is connected via a curved chamfered portion 64d (see FIG. 9). The connection portion between the third inclined surface 64a and the game board surface 13a continues more gently than the connection portion between the first inclined surface 62a and the game board surface 13a, and the connection between the second inclined surface 63a and the game board surface 13a. It is continuous at a steeper angle than the part. The third inclined surface 64a becomes gradually gentler from the first inclined surface 62a side to the second inclined surface 63a side. In other words, the inclination angle θ3 (see FIG. 9) of the third inclined surface 64a with respect to the game board surface 13a is equal to or less than the inclination angle θ1 of the first inclined surface 62a with respect to the game board surface 13a, and the second inclined surface 63a with respect to the game board surface 13a. Is set to be not less than 1 ° and not more than 70 ° (in this embodiment, not less than 17 ° and not more than 49 °). The inclination angle θ3 gradually decreases from the first inclined surface 62a side toward the second inclined surface 63a side.

  As shown in FIGS. 6 and 7, a taper portion (fourth taper portion 67) is provided further downstream of the game ball passage path 81 than the second taper portion 63 in the base plate body 61. . The 4th taper part 67 has the 4th inclined surface 67a which inclines with respect to the game board surface 13a. The inclination angle of the fourth inclined surface 67a with respect to the game board surface 13a is set to the same inclination angle as the inclination angle θ1 (49 °) of the first inclined surface 62a with respect to the game board surface 13a. A screw insertion hole 66 is disposed in the vicinity of the fourth taper portion 67 in the base plate body 61.

(4) Configuration of Collision Prevention Nail 36 As shown in FIGS. 1, 2, 6 to 9, the game nail 35 implanted in the game area 32 includes three collision prevention nails 36. ing. The anti-collision nail 36 at the top of each anti-collision nail 36 is the same game nail as the uppermost game nail 35 a among the game nails 35 implanted in the game area 32. Note that the vicinity of the first taper portion 62 in the base plate body 61 has a low strength because the screw insertion hole 65 is disposed. In addition, a large force is applied to the vicinity of the first taper portion 62 when the screw inserted through the screw insertion hole 65 is screwed to the plate member 31. For this reason, when the game ball A1 directly collides with the first taper portion 62, the first taper portion 62 is likely to crack. Therefore, in the present embodiment, the collision prevention nail 36 allows the game ball A1 launched by the launching device to contact the first taper portion 62 (first inclined surface 62a) without contacting other members (game nail 35, etc.). It tries to prevent a direct collision. In other words, the collision prevention nail 36 has the game with the first taper portion 62 in a state where the momentum of the game ball A1 remains strong, that is, a state where the momentum of the game ball A1 does not decrease due to a collision with another member. The possibility that the ball A1 collides is reduced. Moreover, each collision prevention nail 36 is arrange | positioned along the outer periphery of the 1st taper part 62 and the 3rd taper part 64, and the space | interval of the axial parts of the adjacent collision prevention nail 36 is the diameter (11 of game balls A1). 0.0 mm). Further, the distance between the outer peripheral surface of the shaft portion of each collision prevention nail 36 and the outer peripheral surface of the wall portion 61b of the base plate 60 is larger than the diameter of the game ball A1, specifically 12 mm or more and 20 mm or less (this embodiment). Is set to 15 mm). That is, the distance between the outer peripheral surface of the shaft portion of each collision prevention nail 36 and the outer peripheral surface of the wall portion 61b of the base plate 60 is set to a size that allows at least one game ball A1 to pass smoothly. ing. The upper two anti-collision nails 36 of each anti-collision nail 36 are planted in a region on the side of the third taper portion 64 and in the vicinity of the edge of the third taper portion 64, and the outer peripheral surface of the shaft portion. And the outer peripheral edge of the third taper portion 64 is set to be 1.0 mm or more and 5.0 mm or less (1.0 mm in this embodiment). The remaining one of the collision prevention nails 36 is planted in a region on the side of the first taper portion 62 and in the vicinity of the edge of the first taper portion 62, and the outer peripheral surface of the shaft portion. And the outer peripheral edge of the first taper portion 62 is set to 1.0 mm or more and 5.0 mm or less (1.0 mm in this embodiment). That is, each collision prevention nail 36 is disposed so as to cover the taper portions 62 and 64 and the periphery of the screw insertion hole 65 in a state of being separated from the taper portions 62 and 64 by a predetermined distance.

  Next, a game procedure will be described.

  (A-1) First, the player launches (so-called left-handed) the game ball A1 toward the first route R1 (see FIG. 2) in order to aim at the start winning device 51. When the game ball A1 wins the start winning device 51, a symbol change game for changing the symbol is started.

  (A-2) After the end of the symbol variation game, when a specific condition (a big hit game state, a probability variation state, a variation time shortened state, etc.) is given, the player moves the game ball A1 to the second route R2 (see FIG. (See 2) and launch (right-handed). In this case, the player can launch the game ball A1 at a high speed by turning the operation handle 19 to the right. Therefore, the launch speed of the game ball A1 is very fast and powerful. Therefore, the game ball A1 launched by the launching device and entered the game area 32a reaches the vicinity of the upper center of the center accessory 50 while maintaining a strong momentum. Then, the game ball A1 passes over the second inclined surface 63a of the second taper portion 63 of the base plate 60 and enters the game ball passage path 81 (see arrow F1 in FIG. 6).

  In addition, the game ball A1 that has been launched by the launching device and entered the game area 32a maintains the strongest momentum, that is, the momentum of the game ball A1 due to a collision with another member (such as the game nail 35). It may be guided to the first tapered portion 62 side in a state where there is no decrease. In this case, since the direction of the game ball A1 is changed by colliding with the collision prevention nail 36 and guided to the entrance side of the game ball passage path 81, the collision of the game ball A1 with the first taper portion 62 is prevented. Is done. Then, the game ball A1 rolls on the second inclined surface 63a of the second taper portion 63 and enters the game ball passage path 81 from the entrance (see arrow F2 in FIG. 6).

  (A-3) Thereafter, the game ball A1 moves in the game ball passage route 81 and is guided from the exit of the game ball passage route 81 to the lower right side of the center accessory 50. Then, when the game ball A1 wins the big winning device 52, the payout of the winning ball is performed.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In this embodiment, when the game ball A1 is hit right, it is assumed that the game ball A1 collides with the base plate 60 at the entrance portion of the game ball passage path 81 with a strong momentum. For example, when the game ball A1 collides with a portion having a large inclination angle such as the first inclined surface 62a of the first taper portion 62, the base plate 60 is damaged due to a strong impact, or the game ball A1 jumps to the front side. The movement of the game ball A1 may be adversely affected by being raised. Since the entrance of the game ball passage path 81 is relatively close to the end of the launch path, there is a high possibility that the game ball A1 will collide with the base plate 60 with a strong momentum.

  Therefore, in the pachinko machine 10 of the present embodiment, the base plate 60 at the entrance portion of the game ball passage path 81 is provided with taper portions 62 to 64, and the connection portion between the second inclined surface 63a and the game board surface 13a is provided with the first inclined surface. The surface 62a and the game board surface 13a are connected more slowly than the connection portion. As a result, the momentum of the game ball A1 that has collided with the base plate 60 is received by the gentle second inclined surface 63a, so that the game ball A1 passes smoothly over the second inclined surface 63a. Therefore, it is possible to effectively prevent the base plate 60 from adversely affecting the movement of the game ball A1.

  (2) The screw insertion hole 65 of the present embodiment is provided in the base plate body 61 having higher strength than the tapered portions 62 to 64, 67. Moreover, since the screw insertion hole 65 is thicker than the second taper portion 63, the screw insertion hole 65 is provided in the vicinity of the first taper portion 62 having a higher strength than the second taper portion 63. For this reason, the strength reduction of the base plate 60 due to the provision of the screw insertion hole 65 can be prevented.

  (3) In the present embodiment, since the collision preventing nail 36 is implanted at a position closer to the end of the launch path than the first taper portion 62, the vicinity of the first taper portion 62 is located near the second taper portion 63. It is less likely that the game ball A1 will pass through. Therefore, in the present embodiment, the screw insertion hole 65 is connected to the game ball passage path 81 (particularly, in the vicinity of the second taper portion 63 and the third taper portion 64) that becomes the main route when the game ball A1 is hit to the right. The position is avoided, specifically, in the vicinity of the first taper portion 62. As a result, the possibility that the movement of the game ball A1 is disturbed by the screw inserted through the screw insertion hole 65 is reduced. In addition, since the first taper portion 62 is less likely to pass the game ball A1 in the vicinity, the second taper portion 62 is less likely to adversely affect the movement of the game ball A1 due to the collision of the game ball A1. It is possible to make the tapered portion thicker at a steeper angle than 63. Therefore, even if the thin second taper portion 63 is provided on the base plate 60, the strength of the base plate 60 and consequently the center accessory 50 can be ensured.

  (4) In the present embodiment, the screw insertion hole 66 is disposed in the vicinity of the fourth taper portion 67 in the base plate body 61, but the fourth taper portion 67 has a game ball passage route more than the taper portions 62 to 64. Since it is located on the downstream side of 81, the game ball A <b> 1 whose strength is weakened by passing through the tapered portions 62 to 64 passes through the vicinity of the fourth tapered portion 67. As a result, even if the game ball A1 collides with the screw inserted through the screw insertion hole 66, the possibility that the movement of the game ball A1 is disturbed is reduced.

  (5) In the present embodiment, the distance between the outer peripheral surface of the shaft portion of the collision preventing nail 36 and the outer peripheral surface of the wall portion 61b of the base plate 60 is set to be larger than the diameter of the game ball A1. For this reason, it is possible to prevent ball clogging caused by the game ball A1 entering between the collision preventing nail 36 and the wall portion 61b.

  (6) In the present embodiment, the base plate body 61 is made of a translucent material (for example, a light-transmitting ABS resin colored black), and at least a part of the back surface 61a of the base plate body 61 is a plate member. It arrange | positions so that the opening part 31a of 31 may be faced. Therefore, since it is possible to perform a light emission effect of irradiating the base plate body 61 with light from a movable body or the like attached to the rear side of the plate member 31, an effective impact can be given to the player. In addition, the base plate body 61, which is generally not shining, suddenly shines, so that the player can be surprised. Therefore, the further interest improvement of the pachinko machine 10 can be aimed at.

  In addition, you may change the said embodiment as follows.

  In the above embodiment, the taper portions (the first taper portion 62, the second taper portion 63, and the third taper portion) are formed with respect to the base plate 60 provided at the entrance portion of the game ball passage path 81 in the outer peripheral portion of the center accessory 50. A tapered portion 64) was formed. However, you may provide a taper part in another location. For example, with respect to the base plate 160 (see FIG. 2) formed at least on the terminal portion 182 (see FIG. 2) of the big prize opening path 181 (see FIG. 2) in the outer periphery of the big winning device 52, A first taper portion (not shown) similar to the first taper portion 62, a second taper portion (not shown) similar to the second taper portion 63 of the above embodiment, and a third taper portion 64 of the above embodiment, A similar third taper portion (not shown) may be formed. The special winning opening route 181 is constituted by a plurality of game nails 35, and is a route that guides the gaming ball A1 that has been launched by the launching device and passed through the gaming ball passage route 81 to the big winning device 52. The first taper portion is located on the upstream side of the special winning opening path 181 and has a first inclined surface that is inclined with respect to the game board surface 13a. The second taper portion is located on the downstream side of the big winning opening path 181 with respect to the first taper portion, and has a second inclined surface that is inclined with respect to the game board surface 13a. The outer peripheral edge of the second taper portion has a curved shape along the special winning opening route 181. The third taper portion is located between the first taper portion and the second taper portion, and has a third inclined surface that is inclined with respect to the game board surface 13a. In this case, if the game ball A1 is hit to the right, the game ball A1 may collide with the base plate 160 of the terminal end portion 182 of the big prize winning path 181 with a strong momentum. In this case, there is a possibility that the game ball A1 collides with the base plate 160 and jumps up to the near side, thereby adversely affecting the movement of the game ball A1. Therefore, the first and second taper portions are provided on the base plate 160 of the terminal end portion 182 of the prize winning path 181 so that the connection portion between the second inclined surface and the game board surface 13a is connected between the first inclined surface and the game board surface 13a. It is continuous more slowly than the connected part. In this case, since the game ball A1 that has collided with the base plate 160 passes smoothly on the second inclined surface, the base plate 160 can be effectively prevented from adversely affecting the movement of the game ball A1.

  Further, with respect to the base plate 161 (see FIG. 2) formed at least at the terminal end portion of the start winning opening path 183 (see FIG. 2) in the outer peripheral portion of the start winning device 51, the tapered portions 62 to 64 of the above-described embodiment and Similar first to third tapered portions (not shown) may be formed. The start winning opening route 183 is configured by a plurality of game nails 35, and is a route that guides the game ball A1 that has been launched by the launching device and passed through the game ball passage route 81 to the start winning device 51.

  In the above embodiment, the tapered portions 62, 63, 64 formed on the base plate 60 have the inclined surfaces 62a, 63a, 64a that are the surfaces inclined with respect to the game board surface 13a. However, the inclined surfaces 62a, 63a, 64a are not limited to flat surfaces, and may be curved surfaces (convex surfaces, concave surfaces), for example.
