(Effects of Example)
Next, the operation of the pachinko machine according to the embodiment will be described.

  In the pachinko machine 10 according to the embodiment, the middle frame 12 includes an upper frame member 21, a lower frame member 22, a left frame member 23, and a right frame member 24, and each frame member 21, 22, 23, 24 is a separate member. In addition, each of the ball tank 26 and the tank rail 34 is formed integrally with the upper frame member 21. That is, since it is not necessary to separately attach the ball tank 26 and the tank rail 34, the assembling work can be simplified. Further, unlike the prior art, it is not necessary to extend the functional member 43 to a position above the middle frame 12 in order to attach the ball tank 26 and the tank rail 34. That is, since it is not necessary to secure an installation area for installing and fixing the functional member 43 at a position above the middle frame 12, the opening area 12 a for installing the game board can be expanded above the middle frame 12. Accordingly, the game board 18 having a large vertical dimension can be assembled to the middle frame 12, and the game board 18 is provided with a large symbol display device 20, thereby diversifying the game effects, impact, Improvement can be achieved and the interest of the game can be increased.

  By the way, the pachinko ball S stored in the ball tank 26 needs to be fed to the upper and lower ball trays 14 and 15 disposed below the game board 18 on the front side of the pachinko machine, and in some cases, the first ball. It is necessary to collect the pachinko ball S that has flowed into the passage 53 in a collection basket of the installation frame base. In such a case, the functional member 43 extends to a position above the middle frame 12 and the first and second spherical flow passages 44 and 45 of the functional member 43 are connected to the tank rail 34 in the same manner as in the prior art. In such a configuration, since it is necessary to secure an installation area for the functional member 43 on the side of the middle frame 12, the size of the opening area 12a for installing the game board in the middle frame 12 is limited. Become.

  In contrast, in the embodiment, the tank rail 34 and the first and second spherical flow passages 44 and 45 provided in the functional member 43 are configured to communicate with each other via a separately provided spherical passage unit 50. Thus, the pachinko balls S of the tank rail 34 (ball tank 26) can be reliably fed to the upper and lower ball trays 14 and 15, and the pachinko balls S can be collected in the collecting frame of the installation frame base as needed. . Thus, by providing the ball passage unit 50, the pachinko balls S of the tank rail 34 (ball tank 26) are transferred to the upper and lower ball dishes 14 and 15 without extending the functional member 43 to the vicinity of the tank rail 34. Since the feeding can be performed, the functional member 43 can be formed in a size corresponding to the back side of the lower frame member 22. That is, since it is not necessary to secure the installation area of the functional member 43 on the side of the middle frame 12, the opening area 12a for installing the game board can be expanded in the left-right direction, and the game board 18 having a large left-right dimension. Can be assembled to the middle frame 12. Accordingly, since the large symbol display device 20 can be disposed on the game board 18 in the left-right direction, the diversification of the game effects, the improvement of the impact and the force can be achieved, and the interest of the game can be increased. .

  Here, in the ball passage unit 50, a passage forming portion 52 (first ball passage 53) is formed on the rear end side of the installation portion 55 where the ball dispensing device 101 is installed. The space 57 is defined by the wall 55 and the wall 56. That is, since the passage forming portion 52 (first ball passage 53) and the back surface of the game board 18 are separated from each other, the symbol display device 20 provided on the game board 18 can face the space portion 57. Become. In this way, by allowing the symbol display device 20 to face the space portion 57, the symbol display device 20 interferes with the ball passage unit 50 even when the large symbol display device 20 is disposed in the left-right direction on the game board 18. Inconvenience such as doing can be prevented. Further, since the space portion 57 opens to the front side and the center side of the game board 18 (the side opposite to the side where the ball passage unit 50 is arranged biased), the space portion 57 is accommodated in the space portion 57 like the symbol display device 20. A part of a large component that is not present can face the space 57. In the embodiment, since the symbol display device 20 can face from the opening direction of the space 57, the symbol display device 20 is attached to and detached from the game board 18 (holding means 19) with the ball passage unit 50 attached. It becomes possible. In addition, by providing the drawing wall 56 in the ball passage unit 50, the overall rigidity of the ball passage unit 50 can be achieved. Therefore, as in the embodiment, by installing the ball path unit 50 between the upper frame member 21 (upper support portion 38) and the lower frame member 22 (lower support portion 46), Even when a direct load is applied, damage to the ball path unit 50 can be prevented.

  Incidentally, the tank rail 34 has a second ball path 36 positioned in front of the first ball path 35, and a ball discharge port 36 b is opened in the second ball path 36. That is, since the ball discharge port 36b of the tank rail 34 is provided at a position close to the back surface of the game board 18, the first ball passage 53 of the ball passage unit 50 is moved vertically from the ball discharge port 36b. When configured to extend, it is difficult to secure the space 57 in the front-rear direction, and the symbol display device 20 and the ball path unit 50 may interfere with each other. Therefore, in the embodiment, the first ball inlet 53a connected to the ball discharge port 36b of the tank rail 34 is formed on the front side of the ball passage unit 50 (unit main body 51), and is downward from the first ball inlet 53a. Since the first ball passage 53 is formed to extend in the vertical direction after extending backward as it goes, the size of the space portion 57 in the front-rear direction can be increased, and the large symbol display device 20 can be attached to the unit main body. It is possible to face the space 57 without interfering with 51.

  Further, in the embodiment, the second ball passage 54 formed in the unit main body 51 is inclined to the front side as it goes downward, and the second ball outlet 54b is formed to be positioned on the front end side of the unit main body 51. It is. For this reason, since it is not necessary to extend the 1st ball flow path 44 of the functional member 43 connected to the said 2nd ball path 54 to the back more than necessary, the back protrusion of this functional member 43 is suppressed. Is possible. Therefore, when the pachinko machine 10 is installed on a predetermined installation frame base in an amusement store, interference between various facilities provided on the installation frame base and the functional member 43 can be prevented.

  Further, the opening 55a of the installation portion 55 for attaching and detaching the ball dispensing device 101 is opened and closed by the cover member 90, and the opening 55a is closed by fixing the cover member 90 with one screw. Thus, the ball payout device 101 can be attached and detached simply by removing and tightening the screws, and the attaching and detaching work can be easily performed. Further, since the cover member 90 is pivotally supported by the unit main body 51 via an engagement hook 92 provided on the lower side, the operator holds the cover member 90 in an open state when the screw is removed. You can leave it open without doing. Therefore, the operator can work using both hands, and there is an advantage that workability is improved.

  The cover member 90 is formed with an insertion port 95 at a position corresponding to the ball removal operation unit 103 of the ball dispensing device 101 disposed in the installation unit 55. Accordingly, even when the opening 55 a of the installation portion 55 is closed by the cover member 90, the ball removal operation unit 103 can be operated through the insertion port 95 of the cover member 90. The workability can be improved. In particular, in the manufacturing process of the pachinko machine, it is necessary to completely discharge the pachinko balls S remaining in the ball passage unit 50 before the pachinko machine 10 is shipped. High nature. In such a case, there is an advantage that workability can be effectively improved because the ball removal operation unit 103 may be operated through the insertion port 95 without opening the cover member 90 each time.

  In addition, since the cover member 90 is provided with a shielding member 98 that closes the insertion port 95 so as to be openable and closable, when the ball removal operation portion 103 of the ball dispensing device 101 is not operated, the shielding member 98 The insertion port 95 can be closed, and erroneous operation and unauthorized operation of the ball removal operation unit 103 can be prevented. Further, in the embodiment, after the shielding member 98 is moved to a position where the insertion port 95 is closed, it is difficult to move the shielding member 98 to a position where the insertion port 95 is opened. Therefore, after installation in a game shop where the operation frequency of the ball removal operation unit 103 is extremely low, by closing the insertion port 95 with the shielding member 98, an erroneous operation or unauthorized operation of the ball removal operation unit 103 is prevented. It can be surely prevented. Even if it is difficult to move the shielding member 98 to a position where the insertion port 95 is opened as in the embodiment, as described above, by opening the cover member 90, the ball Since the punching operation unit 103 can be operated, it is possible to operate the ball punching operation unit 103 even in a game store.

  Next, a structure for attaching and detaching the ball passage unit 50 will be described. When the ball passage unit 50 is attached, the protrusion 70 formed on the lower end side of the unit main body 51 is inserted into the lower engagement hole 47 of the lower support portion 46 formed on the functional member 43, thereby Is positioned. At this time, the pivots 71 and 71 formed in the unit main body 51 are pivotally supported by the pivotal support portions 48 and 48 through the upper openings of the pivotal support portions 48 and 48 formed in the lower support portion 46. In this state, when the upper side of the unit main body 51 is swung (adjacent) toward the upper frame member 21, the protruding plate portion 78 formed at the upper position of the unit main body 51 forms the upper support portion formed on the upper frame member 21. 38 abuts. At this time, since the insertion hole 78a of the protruding plate portion 78 and the upper engaging hole 39 of the upper support portion 38 are aligned in the front-rear direction, the engagement of the rotary engaging member 79 provided in the protruding plate portion 78 is achieved. The protrusion 82 enters the upper engagement hole 39. Then, by rotating the rotary engagement member 79 in this state, the engagement protrusion 82 engages with the edge of the upper engagement hole 39, and the upper portion of the unit body 51 is positioned and fixed.

  On the other hand, when the ball passage unit 50 is removed, an operation opposite to that for the attachment may be performed. That is, the rotary engagement member 79 is rotated to release the engagement between the engagement protrusion 82 and the upper engagement hole 39, and the unit main body 51 is swung back (separated). Thereafter, the unit body 51 is lifted upward, and the protruding portion 70 of the unit body 51 is extracted from the lower engagement hole 47 of the lower support portion 46, whereby the ball passage unit 50 can be removed. That is, the ball passage unit 50 engages and disengages the lower engagement hole 47 and the protrusion 70, and the upper engagement hole 39 and the rotary engagement member 79 (engagement protrusion 82), respectively. Since the ball path unit 50 can be attached and detached, the ball path unit 50 can be easily attached and detached.

  Furthermore, since the ball passage unit 50 is configured to be detachable, the symbol display device 20 is disposed on the back side of the game board 18 so as to face the space portion 57 with the ball passage unit 50 removed. A ball passage unit 50 can be attached. On the contrary, in order to remove the symbol display device 20 facing the space 57, the work can be performed after the ball passage unit 50 is once removed. That is, there is an advantage that the ball path unit 50 can be prevented from obstructing the work when performing the attaching / detaching work of the symbol display device 20 to the game board 18 (holding means 19), connecting work of various wirings, and the like. . In the embodiment, the pivot shafts 71 and 71 of the ball passage unit 50 are rotatably supported by the shaft support portions 48 and 48 provided on the lower support portion 46 of the functional member 43. It is also possible to attach and detach the symbol display device 20 simply by tilting the symbol backward. Therefore, the symbol display device 20 can be attached and detached more efficiently. In particular, for work that can be performed without removing the ball path unit 50, such as connecting various wirings, there is an advantage that the workability can be greatly improved.

  Further, the concave portion 84 is formed in the upper portion of the unit main body 51, and the positioning protrusion formed on the upper support portion 38 of the upper frame member 21 is inserted into the concave portion 84. Since the side walls 85 and 85 that define 84 are in contact with the left and right sides of the positioning projection, the positioning of the ball passage unit 50 in the left-right direction can be suitably performed. At this time, the support wall portions 40, 40 formed on the upper support portion 38 of the upper frame member 21 come into contact with the outer surfaces of the side walls 85, 85 of the unit body 51, so The direction can be positioned, and the engaging / disengaging operation of the rotary engaging member 79 and the upper engaging hole 39 can be easily performed.

  When the cover member 90 is opened, the stopper member 63 provided above the installation portion 55 is displaced to the ball passage restriction position by the urging force of the spring member 64. That is, since the restricting piece 63a of the stopper member 63 protrudes into the first ball passage 53 and the pachinko ball S is restricted from reaching the installation portion 55 (the ball dispensing device 101), the first ball The ball dispensing device 101 can be removed from the installation unit 55 without dropping the pachinko ball S in the passage 53 into the installation unit 55.

  On the other hand, when the ball dispensing device 101 is installed in the installation part 55 and the cover member 90 is closed, the presser part 94 provided on the cover member 90 resists the elastic force of the spring member 64 and the stopper member 63. Is displaced from the ball passage restriction position to the ball passage permissible position. For this reason, since the pachinko ball S in the first ball passage 53 can be supplied to the ball dispensing device 101 via the first ball outlet 53b, the pachinko ball according to the operating conditions of the ball dispensing device 101 is obtained. It is possible to pay out the balls S to the upper and lower ball dishes 14 and 15. As described above, the stopper member 63 is configured to be displaced between the ball passage restriction position and the ball passage permission position by opening and closing the cover member 90. Since it is not necessary to individually operate the stopper member 63, the workability of the attaching / detaching work of the ball dispensing device 101 can be improved.

  Further, in the embodiment, the tank bottom surface 27 of the sphere tank 26 is formed so as to be inclined downward from the right frame member 24 toward the left frame member 23, and along the inclination toward the downstream end side of the sphere tank 26. By connecting the tank rail 34 so as to extend in the direction, the vertical size of the ball tank 26 and the tank rail 34 can be made compact while maintaining a state in which the pachinko ball S can flow smoothly. Therefore, it is difficult for game parts such as the symbol display device 20 provided on the game board 18 to come into contact with the ball tank 26 or the tank rail 34, so that a large symbol display device 20 or the like can be arranged by the game board 18. Become. This makes it possible to diversify the game effects, improve the impact and improve the power, and increase the interest of the game.

  Here, as in the embodiment, when the ball tank 26 and the tank rail 34 are integrally formed on the main body of the upper frame member 21, the ball tank 26 and the tank rail 34 face the back side of the main body of the upper frame member 21 ( In the (hidden) configuration, if the thickness of the main body of the upper frame member 21 is reduced in order to expand the opening region 12a of the middle frame 12 upward, it is difficult to ensure a sufficient depth dimension in the ball tank 26. . For this reason, sufficient pachinko spheres S cannot be stored in the sphere tank 26, and there is a high possibility that problems such as ball breakage occur when a large number of pachinko spheres S are discharged, such as big hits. However, in the pachinko machine 10 according to the embodiment, when the ball tank 26 and part of the tank rail 34 face the rear of the opening area 12a of the middle frame 12, and the game board 18 is installed in the opening area 12a of the middle frame 12. The ball tank 26 and the tank rail 34 are configured to overlap the game board 18 in the front-rear direction. For this reason, since the depth dimension of the sphere tank 26 can be increased and the volume of the storage space 32 can be increased, a large number of pachinko balls S can be stored in the sphere tank 26.

  In addition, by making each frame member 21, 22, 23, 24 of the middle frame 12 a separate member that can be separated, the formability when the ball tank 26 and the tank rail 34 are integrally formed is improved, and the manufacturing cost is reduced. Can be planned. Also, by making each frame member 21, 22, 23, 24 a separate member, only the damaged frame members 21, 22, 23, 24 can be replaced, which contributes to cost reduction and waste reduction. There are benefits to get.

  Next, the operation of the protective cover 110 that protects the back side of the game board 18 will be described. By inserting each support shaft 116 of the protective cover 110 (the cover main body 111 and the fraud prevention portion 123) from above into the shaft hole 24b of the bearing portion 24a formed in the right frame member 24 of the middle frame 12, The protective cover 110 is assembled so that it can be opened and closed. In this state, the protective cover 110 is closed, and the locking portions of the fixtures 119 provided on the upper surface portion 113 and the second side surface portion 115 are used as the rear wall portion 29 of the upper frame member 21 and the ball passage unit 50. The protective cover 110 can be held in a closed state by being inserted into the locking cylinder portions 29a and 52b formed in the passage forming portion 52 and pressing the fixing tool 119 from the fixing release position to the fixing position. Here, when the protective cover 110 is closed, the first and second positioning pieces 120 and 121 formed on the upper surface portion 113 and the second side surface portion 115 of the protective cover 110 are connected to the rear wall portion 29 and the ball. The rotation of the protective cover 110 is restricted by contacting the passage forming portion 52 of the passage unit 50. That is, since the fixing tool 119 can be easily aligned, the protective cover 110 can be fixed easily.

  On the other hand, when the protective cover 110 is opened, each fixing tool 119 is pulled to release the engagement between the locking portion of each fixing tool 119 and the corresponding locking cylinder portion 29a, 52b. Therefore, the protective cover 110 can be easily opened and closed. Accordingly, it is possible to easily perform replacement work, maintenance work, etc. of the symbol display device 20 disposed inside the protective cover 110 (cover body 111). Here, when the engagement between the fixing tool 119 and the locking cylinder portions 29a and 52b is released and the protective cover 110 is opened, the second position restricting protrusion 114a formed on the protective cover 110 is moved to the right side. The opening of the frame member 24 is restricted by contacting with the first position restricting protrusion 24c. Thus, by providing the first and second position restricting protrusions 24c and 114a to limit the opening range of the protective cover 110, the protective cover 110 is inadvertently attached to another member when the protective cover 110 is opened. Contact can be prevented, and damage to the protective cover 110 and other members can be prevented.

  Further, in a state where the pachinko machine 10 is installed on the installation frame base of the amusement store, in order to open the protective cover 110, the middle frame 12 is opened with respect to the outer frame 11 with respect to the middle frame 12. It is necessary to open the protective cover 110. Since the protective cover 110 is pivotally supported on the right frame member 24 opposite to the left frame member 23 that pivotally supports the middle frame 12 with respect to the outer frame 11, the protective cover must be opened unless the opening of the protective cover 110 is restricted. It is conceivable that 110 will greatly jump out to the side of the aisle in the amusement store, hindering the passage of the passage, and touching the protective cover 110 during passage. On the other hand, in the embodiment, since the opening range of the protective cover 110 can be limited by the first and second position restricting protrusions 24c and 114a as described above, when the protective cover 110 is opened, the protection is performed. It is possible to prevent the cover 110 from greatly jumping out into the aisle in the amusement store, and it is possible to prevent the cover 110 from being damaged due to contact with the protective cover 110 during passage of the aisle.

  When the protective cover 110 is pivotally supported on the left frame member 23 that pivotally supports the middle frame 12 with respect to the outer frame 11, the middle frame 12 is made larger than the outer frame 11 when the protective cover 110 is opened. There is a problem that workability is inferior because it needs to be opened. In contrast, in the embodiment, the protection cover 110 is pivotally supported on the right frame member 24 opposite to the left frame member 23 that pivotally supports the middle frame 12 with respect to the outer frame 11. When the cover 110 is opened, it is not necessary to open the middle frame 12 greatly, so that there is an advantage that the convenience of opening and closing the protective cover 110 is improved.

  Here, the rear side of the symbol display device 20 disposed on the game board 18 is covered with the protective cover 110, and the portion facing the space 57 of the ball passage unit 50 is covered with the ball passage unit 50. Protected. That is, even if the pachinko ball S falls from the ball tank 26 or the tank rail 34, the pachinko ball S does not enter the inside of the protective cover 110, so that the pachinko ball S comes into contact with the symbol display device 20. This will not cause any damage. Since the upper surface portion 113 of the protective cover 110 is inclined, it is possible to prevent the fallen pachinko ball S from stopping on the upper surface portion 113 as described above. The second positioning piece 121 is formed over substantially the entire length of the upper surface portion 113 in the left-right direction, and the second positioning piece 121 is configured to abut against the rear wall portion 29 of the upper frame member 21. The pachinko balls S falling from the ball tank 26 and the tank rail 34 can reliably be prevented from entering the inside of the protective cover 110 from between the upper surface portion 113 and the rear wall portion 29.

  In the embodiment, the protective cover 110 is pivotally supported by the right frame member 24 of the middle frame 12, and the fixing member 119 of the protective cover 110 is formed on each of the ball path unit 50 and the upper frame member 21. By being configured to be engaged with the cylindrical portions 29a and 52b, there is no need to separately arrange a member for pivotally supporting the protective cover 110 and a member for fixing the fixing tool 119 on the inner frame 12. Furthermore, as described above, the ball path unit 50 is installed on the upper frame member 21 and the lower frame member 22 so as to overlap the game board 18 in the front-rear direction. Therefore, the opening area 12a of the middle frame 12 can be expanded to the maximum on the left and right frame members 23, 24 side, and the game board 18 enlarged in the left-right direction can be provided. It is possible to improve the game and increase the fun of the game. Further, since the ball passage unit 50 is installed at a position biased toward the left frame member 23 located on the side opposite to the right frame member 24 that pivotally supports the protective cover 110, Even if the protective cover 110 is configured to be fixed, the large symbol display device 20 disposed on the game board 18 can be reliably protected.

  The middle frame 12 functions as an installation member for various gaming machine components such as the gaming board 18 and the front frame 13, and therefore has a very high rigidity in various gaming machine components in the pachinko machine 10. Formed. That is, as in the embodiment, the protective cover 110 is pivotally supported on the right frame member 24 of the middle frame 12, and the load of the protective cover 110 is supported by the right frame member 24. It is possible to prevent an unnecessary load from being applied to the ball passage unit 50 to which 110 is fixed. Here, as described above, since the ball path unit 50 is detachably installed between the upper frame member 21 and the lower frame member 22, a load reduction on the ball path unit 50 is required. Therefore, in the embodiment, the fixture 119 provided at the upper end portion of the protective cover 110 is configured to be detachably fixed to the locking cylinder portion 29a provided on the upper frame member 21 of the middle frame 12. Therefore, the protective cover 110 can be supported in a distributed manner, the load on the ball path unit 50 can be reduced, and the stability of the protective cover 110 is improved.

  By the way, as described above, the pachinko machine 10 is configured such that a plurality of pachinko machines 10 are juxtaposed by fixing the outer frame 11 to an installation frame base of a game store. In this case, a slight gap may occur between adjacent pachinko machines 10. That is, if such a gap is generated, there is a possibility that a foreign matter such as a wire inserted from the gap is caused to enter the game board 18 side and an illegal act is performed. Therefore, in the embodiment, the protective cover 110 (the cover main body 111 and the fraud prevention unit 123) is provided on the right frame member 24 side, and a foreign object is temporarily inserted through a gap generated between the right frame member 24 and the outer frame 11. Even if it is done, since the foreign matter can be prevented from entering the game board 18 side, it is possible to effectively prevent fraud.

  Further, in order to be able to easily perform wiring connection, replacement, maintenance work, etc. to the sub control device 104 disposed on the back side of the game board 18, the back of the sub control device 104 is not covered with the cover body 111, Opening is preferred. In this case, as shown in the embodiment, the illegal act prevention unit 123 is provided separately, so that foreign matter can be prevented from entering the portion corresponding to the sub control device 104 in the game board 18 and the wiring to the sub control device 104 can be prevented. Convenience such as connection, exchange, and maintenance work can be secured. In addition, since the fraud prevention part 123 is formed so as to open to the front, rear, and left frame members 23 side, the members disposed on the game board 18 and the functional members are exposed to the inside of the fraud prevention part 123. There is also an advantage that the space can be effectively used.

[Example of change]
The configuration of the gaming machine is not limited to that of the embodiment, and various changes can be made. For example, in the embodiment, the protective cover is composed of the cover body and the fraud prevention unit, but it may be composed of only the cover body. Moreover, it is also possible to configure so that the cover body and the fraud prevention part can be opened and closed independently. Further, the shape and size of the protective cover are not limited to those in the embodiment, but are set to a shape and size that can protect the symbol display device and other game members protruding from the back side of the game board. What should I do? Note that the gaming parts that are disposed on the gaming board and protected by the protective cover are not limited to the symbol display device of the embodiment, but an electric prize of a type in which a pachinko ball is won by operating a movable member. Various components arranged on the back side of the game board, such as a device and various control devices, can be employed.

  In the embodiment, the protective cover is detachably fixed to the ball path unit and the upper frame member of the middle frame, but may be fixed only to the ball path unit. Moreover, as the fixing means for attaching and detaching and fixing the protective cover, in the embodiment, a retractable fixing tool is used, but the invention is not limited to this, and various conventionally known fixing means can be adopted. is there. Similarly, the pivot means for pivotally supporting the protective cover is not limited to the embodiment, and any conventionally known pivot means can be arbitrarily selected and employed.

  In the embodiment, the ball payout device is installed at the lower position of the ball passage unit. However, the present invention is not limited to this, and the installation portion may be provided at the upper position of the ball passage unit. That is, the installation portion may be configured to be formed in the middle of the path of the ball path formed in the ball path. In the present invention, “on the way of the ball passage” means a ball inlet (first ball inlet 53a in the embodiment) connected to the tank rail in the ball passage unit and a ball connected to the ball flow passage of the functional member. It shows between exits (second ball exit 54b in the embodiment). Accordingly, a spherical inlet (first spherical inlet 53a in the embodiment) connected to the tank rail in the spherical passage unit is opened in the installation portion, or a spherical outlet (second secondary in the embodiment) connected to the spherical flow path of the functional member. It is also possible to open the ball outlet 54b) in the installation part.

  In the embodiment, the ball passage unit is installed at a position biased toward the left frame member side with respect to the upper frame member and the lower frame member (functional member), but the invention is not limited to this. Depending on the formation position of the spherical flow passage, it can be installed at any position of the upper frame member and the lower frame member (functional member). Here, in the embodiment, the protective cover is configured to pivotally support the right frame member of the middle frame. However, the ball path unit is biased toward the right frame member of the middle frame in the upper frame member and the lower frame member (functional member). It can also be installed at a different position. However, in this case, the protective cover is preferably pivotally supported on the left frame member of the middle frame. That is, the ball path unit is installed between the upper frame member and the lower frame member at a position biased toward the right frame member side of the middle frame, and the protective cover is pivotally supported on the left frame member of the middle frame. As with the example, the back side of the game board can be protected. In this way, the protective cover can be configured to pivot on one of the left and right side frame members according to the position where the ball passage unit is installed. From the viewpoint of the convenience of opening and closing the protective cover, the protective cover has an upper frame member and a lower frame that are biased toward the side frame member that pivotally supports the middle frame with respect to the outer frame. It is preferable that the protective cover is pivotally supported on the side frame member opposite to the side frame member that pivots between the members and pivotally supports the middle frame with respect to the outer frame.

  In the present invention, the “upper frame member for installing the ball passage unit” is not limited to the structure in which the ball passage unit is directly attached to the main body of the upper frame member, but the ball tank or tank rail provided on the upper frame member is It includes a configuration for installing the passage unit. Similarly, the “lower frame member for installing the ball passage unit” in the present invention is not limited to the configuration in which the ball passage unit is directly attached to the main body of the lower frame member, but the functional member provided on the lower frame member may be a ball passage unit. Including a structure for mounting.

  In the embodiment, the ball passage unit is disposed at a position biased to either the left or right side, and the space portion is defined so as to open to the front side and the side opposite to the side on which the ball path unit is biased. If configured so as to be opened, it is possible to allow the game parts provided on the back side of the game board to face the space. In addition, by configuring the left and right side portions of the space portion in the ball passage unit to be open, even when the ball passage unit is installed near the center of the upper frame member and the lower frame member (functional member), a large size is provided in the space portion. Of game parts.

  In the embodiment, the first spherical passage formed in the spherical passage unit is formed in a bent shape that is inclined forward at the upper position thereof, but extends in a substantially vertical direction from the rear position of the installation portion. Also good. That is, the ball inlet (first ball inlet) of the first ball passage is formed to open upward at the rear end of the unit main body, and the ball discharge port of the tank rail is formed at a position corresponding to the ball inlet. By forming, a large area of the space portion can be secured. Similarly, the second spherical passage formed in the spherical passage unit is formed so as to incline forward at a position below the second spherical passage. However, the second spherical passage may extend in a substantially vertical direction from the rear position of the installation portion.
