Description

  The present invention relates to a gaming machine that rectifies and passes game balls stored in a ball tank through tank rails.

  Pachinko machines, which are typical gaming machines, are detachably arranged on the outer frame that is installed in a vertical orientation on the gaming machine installation frame base (commonly called `` Island ''), with a holding part that opens back and forth. The installed middle frame is assembled so as to be openable and detachable. And, on the front side of the middle frame, a front frame assembled with a glass plate that protects the game board from see-through, upper and lower ball dishes, a ball hitting device for launching pachinko balls (game balls), etc. In addition, various ball processing units, control devices, and the like are provided on the back side of the middle frame for use in games.

  A ball tank to which pachinko balls from a ball supply facility provided on the installation frame base are supplied is assembled at an upper position on the back side of the middle frame. The ball tank includes a tank portion in which a space capable of storing pachinko balls is internally defined, and a tank rail is provided downstream from the tank portion. The pachinko balls stored in the ball tank are rectified in one row while flowing down the tank rail, and are sent to the ball dispensing device downstream. Then, by the operation of the ball dispensing device, a predetermined number of pachinko balls are paid out as rental balls or prize balls to the upper and lower ball trays provided in the front frame.

  By the way, the pachinko balls stored in the ball tank are sent to the tank rail while being stacked in an unordered state, and therefore, pachinko balls are likely to be clogged upstream of the tank rail. Therefore, various functions / mechanisms have been adopted for conventional tank rails so that pachinko balls can flow in a line. For example, Patent Document 1 proposes a tank rail in which the channel of the tank rail is devised so that the pachinko balls are aligned while flowing down.

The height of the partition 40 is set to be substantially the same as the depth of the ball tank 30.

(About the sphere leveling area 45)
The tank rail 31 is connected to the tank bottom surface 32 of the ball tank 30 with its upstream end lowered by about one pachinko ball P from the upstream end to the downstream end (second side frame portion). It extends substantially linearly (from the 26th side toward the first side frame 25 side). In addition, the width dimension (front-rear dimension) of the tank rail 31 is set to a size that allows one pachinko ball P to pass through, and the bottom surface 44 of the tank rail 31 is an inclined step portion that forms a sphere leveling area 45 to be described later. The whole except 46 and 47 is inclined downward from left to right, and is set to the same angle as the inclination angle of the tank bottom surface 32. A spherical leveling region 45 as a rectifying unit for rectifying the pachinko ball P is formed at a substantially central position in the longitudinal direction of the tank rail 31. As shown in FIG. 6 and FIG. 7, the spherical leveling region 45 includes a first oblique step 46 constituting the upstream bottom surface in the spherical leveling region 45 and a downstream side in the spherical leveling region 45. The second slanted step portion 47 constituting the bottom surface and the bent portion 48 forming the front and rear side surfaces of the sphere leveling region 45.

The first inclined step 46 is connected to the bottom surface 44 a upstream of the sphere leveling region 45 in the tank rail 31 by one step, and the connecting portion constitutes a first step 49. The first inclined step 46 is gently inclined downward in a direction perpendicular to the inclination direction (left-right direction) of the tank rail 31 (a direction from the front to the rear, see arrow A in FIG. 7). That is, as shown in FIG. 6, the first stepped portion 49 formed by the upstream bottom surface 44a and the first oblique stepped portion 46 has a rectangular shape that widens from the front to the rear (increases the step). The maximum step l ₁ at the rear end position of the first step portion 49 is set to approximately one fifth of the size of the pachinko ball P. Accordingly, the pachinko sphere P flowing down the first oblique step 46 is urged rearward by its own weight along the slope of the first oblique step 46. The first inclined step 46 is not inclined downward from the left to the right like the upstream bottom surface 44a and the downstream bottom surface 44b of the tank rail 31, and is horizontal with respect to the left-right direction. It has become.

  A second oblique step 47 provided on the downstream side of the first oblique step 46 is connected to the first oblique step 46 so as to be lowered by one step, and both the first and second oblique steps 46 are connected. A second step portion 50 is formed at the connection portion between the portions 46 and 47. The second oblique step 47 is connected to the bottom surface 44b on the downstream side of the tank rail 31 and is connected to the connection portion between the second oblique step 47 and the bottom 44b. A part 51 is formed.

The second oblique step 47 is inclined downward in the direction opposite to the inclination direction of the first oblique step 46 (in the embodiment, the direction from the rear to the front, see arrow B in FIG. 7). That is, as shown in FIG. 6, unlike the first step portion 49, the second step portion 50 formed by the first oblique step portion 46 and the second oblique step portion 47 is narrowed from the front to the rear ( It has a rectangular shape (the step becomes smaller), and the maximum step ₁₂ is located at the front end. On the other hand, the third step portion 51 bottom surface 44b of the second slant step portion 47 and the downstream forms are spread over from front to back (step increases) a rectangular shape, the maximum step l ₃ the rear end Located in. The maximum steps l ₂ and l ₃ of the second step portion 50 and the third step portion 51 are set to approximately one-fifth the size of the pachinko sphere P, like the first step portion 49. . Accordingly, the pachinko ball P urged rearward in the first oblique step 46 is urged forward by its own weight along the second oblique step 47. Note that, similarly to the first oblique step 46, the second oblique step 47 is not inclined with respect to the left-right direction. Thus, the first oblique step 46 and the second oblique step 47 have a structure that is lowered step by step from upstream to downstream in the tank rail 31, and the first to third step portions 49. , 50 and 51, when the pachinko sphere P passes through, the pachinko sphere P is finely oscillated up and down, and the pachinko sphere P is efficiently rectified (spherical equalization).

  As shown in FIG. 6, the front and rear edges of the first oblique step 46 and the second oblique step 47, the first oblique step 46, the second oblique step 47, and the bent portion. Dust discharging through holes 52 and 52 are respectively opened at the portion where the portion 48 is joined, and dust entering the tank rail 31 is discharged through the through holes 52 and 52.

  As shown in FIG. 7, the bent portion 48 is composed of a rear wall portion 48a and a front wall portion 48b and is curved in the front-rear direction. The portion 46 and the second oblique step portion 47 meander along the inclination direction. The rear wall portion 48a gradually moves rearward as the portions corresponding to the first oblique step portion 46 and the second oblique step portion 47 move from the first oblique step portion 46 side toward the second step portion 50. After curving so as to retract, it is curved so as to gradually protrude forward from the second stepped portion 50 toward the second inclined stepped portion 47 side, and as a whole, left and right across the second stepped portion 50 It has a series of arc shapes recessed backwards. Further, the front wall portion 48b is gradually moved from the first oblique step portion 46 side toward the second step portion 50 at portions corresponding to the first oblique step portion 46 and the second oblique step portion 47. After curving so as to protrude rearward, it curves so as to gradually retract forward from the second stepped portion 50 toward the second oblique stepped portion 47 side, and corresponds to the second stepped portion 50 as a whole. In addition to forming a shape projecting rearward at the position, the surfaces of the first oblique step 46 and the second oblique step 47 are recessed in a concave shape. That is, a portion of the bent portion 48 corresponding to the first oblique step 46 is curved toward the rear, which is the flow direction (downward inclination direction) of the first oblique step 46. On the other hand, the portion of the bent portion 48 corresponding to the second oblique step portion 47 is configured to bend toward the front, which is the flow direction (downward inclination direction) of the second oblique step portion 47. The pachinko sphere P flowing down the sphere leveling region 45 by the first oblique step 46, the second oblique step 47, and the bent portion 48 causes the inclination direction of the first and second oblique steps 46, 47 to be inclined. The direction in which the ball pressure is applied by the flowing down pachinko sphere P is changed, and the pachinko sphere P is rectified (sphere equalized).

  As shown in FIG. 8, at the downstream end of the bottom surface 44b on the downstream side of the tank rail 31, a ball discharge port 53 that opens in the vertical direction is provided.

And a support plate 61 that extends rearward from the upper opening of the tank rail 31 toward the left at the left end of the lid 58 (the end facing the sphere tank 30 side). As shown in FIG. 4, the ball storage portion 27 is provided with a mounting portion 62 that extends rearward from the upper end of the upper opening on the rear side of the upper opening of the tank rail 31. The front and rear dimensions of the lid part 58 are set larger than the upper opening of the tank rail 31, and the rear part of the lid part 58 is placed on the placement part 62, so that the upper part opening is opened at the front part of the lid part 58. Set to cover. The support plate portion 61 is set to have substantially the same front-rear width as the placement portion 62. With the support plate portion 61 placed on the placement portion 62, the upper opening above the spherical leveling region 45 is opened. It is designed to be opened.

  A first engagement hole 62a is formed at the downstream end (right end) of the placement portion 62, and a second engagement hole 62b is formed at the upstream end (left end) of the placement portion 62. Yes. Further, the rectifying member 57 is provided with a first claw piece 63a detachably engaged with the corresponding first engagement hole 62a at the right end portion of the lid portion 58, and at the left end portion of the support plate portion 61. , Second claw pieces 63b that are detachably engaged with the corresponding second engagement holes 62b are provided. An operation piece 61a protruding upward is provided at the left end of the support plate 61, and the second claw piece 63b can be elastically deformed by the operation of the operation piece 61a. That is, the first claw piece 63a is inserted into the first engagement hole 62a from the upper side and engaged with the hole edge, and the second claw piece 63b is pushed into the second engagement hole 62b from the upper side. After the second claw piece 63b is elastically deformed and inserted into the second engagement hole 62b, the second claw piece 63b is elastically restored and engaged with the edge of the hole, whereby the rectifying member 57 opens the upper opening on the downstream side of the spherical leveling region 45. It is attached to the sphere storage part 27 in a state covered with the lid part 58 (see FIG. 3). Then, by operating the operation piece 61a, the second claw piece 63b is elastically deformed to release the engagement with the hole edge and withdrawn from the second engagement hole 62b, thereby removing the rectifying member 57 from the ball storage portion 27. Be able to. In the embodiment, the rectifying member 57 is made of synthetic resin, and the support plate 61 is cut to a predetermined length in the front-rear direction on the right side (the lid 58 side) from the formation portion of the second claw piece 63b and the operation piece 61a. By lacking, the second claw piece 63b can be easily elastically deformed. Further, a positioning recess 64 is formed at the upper end of the front wall that defines the tank rail 31, and a regulating piece 58 a is projected from the front end edge of the lid portion 58, and the regulating piece 58 a is fitted into the positioning recess 64. Thus, the rectifying member 57 is configured to be positioned in the front-rear and left-right directions with respect to the ball storage unit 27.

  On the lower surface of the lid portion 58, the rectifying guide portion 59 extending into the tank rail 31 is provided as shown in FIG. The rectifying guide portion 59 is located substantially at the center of the front and rear width of the tank rail 31 and extends from the downstream end of the sphere leveling region 45 (downstream end of the second oblique step portion 47) to above the sphere discharge port 53. The pachinko ball P extending between the two and flowing down the tank rail 31 can be guided by the lower surfaces 65 and 66. The distance between the lower surfaces 65 and 66 of the alignment guide portion 59 (the lower surface of the rectifying member 57) and the bottom surface 44b on the downstream side of the tank rail 31 is set so as to gradually decrease from the upstream side toward the downstream side. Further, the upstream edge N of the inlet 53a of the sphere outlet 53 (the edge of the bottom surface 44b and the boundary between the bottom surface 44b and the sphere outlet 53) and the upstream edge N on the vertical line and the rectifying guide portion. The distance R between the lower surface 65 and 66 of 59 is set to be larger than one pachinko ball P and smaller than two (see FIG. 9). As a result, it is possible to restrict the passage of the two pachinko balls P into the ball discharge port 53 in a state where they overlap each other.

  As shown in FIGS. 8 and 9, the lower surfaces 65 and 66 of the rectifying guide portion 59 are connected to the downstream end of the first curved surface 65 that protrudes downward from the upstream end side toward the downstream side. A second curved surface 66 that protrudes upward is formed from the connecting portion with the curved surface 65 toward the downstream side, and the lower surfaces 65 and 66 of the rectifying guide portion 59 are substantially S-shaped as a whole. In the embodiment, a connecting portion Q between the first curved surface 65 and the second curved surface 66 is located on a vertical line passing through the upstream edge N of the inlet 53 a in the ball discharge port 53. The first curved surface 65 is convex downward with respect to the line segment F1 connecting the starting point Q1 of the first curved surface 65 and the connection portion Q, and the second curved surface 66 is connected to the connection portion Q and the second portion. It is convex upward with respect to the line segment F2 connecting the end Q2 of the curved surface 66.

  Further, as shown in FIG. 9, an extension guide portion 67 extending toward the ball discharge port 53 along the right side wall 60 is provided at the downstream end of the rectifying guide portion 59. The extension guide portion 67 protrudes downward from a height position K of one pachinko ball P from the upstream side edge N on a vertical line passing through the upstream side edge N of the inlet 53 a, and the bottom surface of the tank rail 31. The extension guide portion 67 prevents the pachinko ball P flowing on the right side wall 44 from directly hitting the right side wall 60. Further, the vertical spacing L between the lower end of the extending guide portion 67 and the outlet 53b of the ball discharge port 53 is set to be shorter than that of one pachinko ball P. Further, the extension guide portion 67 faces the guide surface 56 of the ball discharge port 53, and the gap between the extension guide portion 67 and the guide surface 56 is dimensioned to allow one pachinko ball P to pass through. Set to Thus, the pachinko ball P flowing on the bottom surface 44b of the tank rail 31 is prevented from directly hitting the right side wall 60 by the extension guide portion 67, and the ball drainage of the pachinko ball P hitting the extension guide portion 67 is prevented. The passage to the outlet 53 is allowed. The second curved surface 66 is formed up to the middle of the surface of the extended guide portion 67 that faces the guide surface 56 of the ball discharge port 53, and the pachinko sphere P extends along the second curved surface 66. The ball discharge port 53 can be smoothly guided.

  Here, the distance from the start surface (connecting portion Q) to the terminal end Q2 of the second curved surface 66 is gradually increased from the start end (connecting portion Q) of the second curved surface 66 to the terminal end Q2. It is set to be narrow. The distance from the end Q2 to the guide surface 56 from the point corresponding to the end Q2 of the second curved surface 66 in the extended guide 67 to the lower end (edge on the guide surface side) of the extended guide 67 is also from the end Q2. The distance between the lower end and the guide surface 56 is set to be slightly larger than the diameter of the pachinko ball P. Thereby, the pachinko balls P can pass one by one between the lower end of the extension guide portion 67 and the guide surface 56, and the ball clogging can be surely prevented.

  As shown in FIG. 9, the inlet 54a of the spherical passage 54 in the spherical passage unit 29 is formed so as to expand upward (the spherical outlet 53), and at the left edge (tank rail 31) of the inlet 54a. The upstream edge in the flow direction of the pachinko sphere P) and the front and rear edges are positioned outside the corresponding edge of the outlet 53b in the ball outlet 53. Further, the right edge (the edge on the downstream side in the flow direction of the pachinko ball P on the tank rail 31) at the inlet 54a of the ball passage 54 is located outside the extension line extending downward from the inner surface of the right side wall 60. Set to do. As a result, the pachinko sphere P passed through the ball discharge port 53 can be smoothly received into the inlet 54a.

(Operation of Example)
Next, the operation of the pachinko machine 10 according to the embodiment will be described. When the pachinko sphere P is supplied from a sphere supply facility (not shown) to the storage space 34 of the sphere tank 30, the pachinko sphere P is accommodated in the storage space 34 in a state of overlapping vertically. These pachinko balls P flow by their own weight toward the tank rail 31 along the inclination direction of the tank bottom surface 32. Further, the pachinko ball P located on the ball guiding surface 33d is promptly guided to the tank bottom surface 32 and the tank rail 31 side.

  Here, the capacity of the pachinko balls P stored in the ball tank 30 can be adjusted by moving the partition member 38 in the left-right direction with respect to the rear wall 33b of the ball tank 30. That is, the main body 39 of the partition member 38 is gripped, moved in the left-right direction, and stopped at an arbitrary position, whereby the engaging portion 42 of the partition member 38 is elastically engaged with the engaged portion 37d of the guide member 37. Engage and the partition member 38 is held in the adjusted position. As a result, the size of the storage space 34 defined between the partition portion 40 of the partition member 38 and the ball guiding surface 33d changes in the left-right direction, and the capacity of the pachinko sphere P that can be stored in the storage space 34 is increased. Change. The partition member 38 is easily detached from the guide member 37 by moving the support portions 41, 41 supported by the guide member 37 to a position coincident with the mounting openings 37c, 37c and pulling them out to the front side. be able to. Therefore, when the partition member 38 is damaged, the partition member 38 can be easily replaced.

  The pachinko balls P that have flowed to the tank rail 31 flow down the bottom surface 44a on the upstream side of the tank rail 31, and flow into the sphere leveling region 45 in a single row while being vertically overlapped. It moves over the part 49 to the first oblique step part 46. At this time, the pachinko ball P vibrates in the vertical direction due to the impact dropped on the first oblique step 46, and is given the first rectifying action. That is, the leveling of the pachinko spheres P that overlap vertically is performed efficiently.

  As shown in FIG. 7, the pachinko sphere P that has arrived at the first oblique step 46 is guided by the inclined surface and the bent portion 48 of the first oblique step 46 and rearward (upper side in FIG. 7). It is forcibly moved to. Thereby, the second rectification action is given to the pachinko sphere P, and the upper and lower overlapping of the pachinko spheres P is further eased. Subsequently, when the pachinko sphere P exceeds the second stepped portion 50, it vibrates on the second oblique stepped portion 47 and a third rectifying action is given. When the pachinko sphere P flows down on the second oblique step 47, this time, due to the inclined surface of the second oblique step 47 and the bent portion 48, the front opposite to the first oblique step 46 (FIG. 7 is forcibly moved downward), and a fourth rectifying action is given to the pachinko sphere P. That is, the pachinko sphere P that has been forcibly moved backward by the first oblique step 46 is immediately forcibly moved in the reverse direction by the second oblique step 47 to give a strong rectifying action to the pachinko sphere P. Will be. Next, when passing through the second oblique stepped portion 47, the pachinko ball P vibrates in the vertical direction at the third stepped portion 51 and is given a fifth rectifying action.

  That is, when the pachinko spheres P that are vertically overlapped flow down the sphere leveling region 45, vibrations in the vertical direction at the first to third step portions 49, 50, 51 with respect to the pachinko spheres P, By giving the shaking in the front-rear direction by the first and second inclined step portions 46 and 47 and the bent portion 48 substantially simultaneously, a sufficient rectifying effect is exhibited even at a short distance. Therefore, as shown in FIG. 8, the pachinko balls P that have flowed into the tank rail 31 in a state where they are vertically overlapped are suitably rectified while passing through the sphere leveling region 45, and the downstream side of the tank rail 31 is arranged in a row 1. It flows down in steps.

  As described above, by providing the sphere leveling region 45 on the tank rail 31, the pachinko ball P can be efficiently rectified even at a short distance, so that the tank rail 31 can be made compact. That is, even in the recent pachinko machine 10 in which the installation space is being limited with the increase in the size of the game board 12, it is possible to install the ball storage unit 27 having a sufficient leveling effect. Moreover, the volume of the ball tank 30 can be increased by the amount that can make the tank rail 31 compact, and the number of balls that can be stored in the ball tank 30 can be increased. Furthermore, when the ball tank 30 and the tank rail 31 are integrally formed to form the ball storage portion 27 as in the embodiment, the length of the tank rail 31 cannot be changed. By providing the region 45, a sufficient rectifying effect can be exhibited without changing the length of the tank rail 31.

  Here, since a large amount of pachinko balls P circulate in the ball tank 30 and the tank rail 31, dust in a game store or the like may enter the ball storage unit 27. And if this dust exists in the narrow tank rail 31, the distribution | circulation of the pachinko ball P may be inhibited and it may become a factor which ball clogging produces. In particular, the joining portion of the first and second oblique step portions 46 and 47 and the bent portion 48 is a portion where the flow direction of the pachinko sphere P is changed, and thus is a portion where dust tends to accumulate. And when such dust accumulates, it will become a hindrance when the pachinko ball P flows down, and the rectification effect in the spherical equalization area | region 45 will fall. Therefore, in the embodiment, since the through holes 52 and 52 are opened in the joint portion of the first and second oblique step portions 46 and 47 and the bent portion 48, the dust through holes 52 and 52 accumulated in the portion are provided. It is possible to discharge to the outside through the flow path, to eliminate the cause of hindering the flow of the pachinko sphere P, and to suppress the reduction of the rectification effect.

  The pachinko balls P that have passed through the sphere leveling region 45 flow down the bottom surface 44b on the downstream side of the tank rail 31 and fall downward from the ball discharge port 53. This pachinko ball P enters the ball passage 54 from the inlet 54 a of the ball passage unit 29 and is temporarily stored inside the ball passage unit 29. Then, when the ball dispensing device 55 is operated at a predetermined timing, the pachinko balls P inside the ball passage unit 29 are sent to the ball tray 16 via the ball outlet guide portion 28 as prize balls or rental balls. Be paid.

  Here, depending on the supply state of the pachinko sphere P from the sphere supply facility to the sphere tank 30 while the pachinko sphere P that has passed through the sphere leveling area 45 reaches the sphere discharge port 53, There is a possibility that the pachinko sphere P once rectified may overlap again and again. Therefore, in the embodiment, the pachinko sphere P is reliably placed in the ball discharge port 53 by arranging the rectifying member 57 between the downstream end of the ball leveling region 45 and the upper side of the ball discharge port 53. It flows in a state of one row and one stage.

  That is, the lower surfaces 65 and 66 of the rectifying guide portion 59 of the rectifying member 57 located above the bottom surface 44b are inclined downward from the upstream side toward the downstream side over the entire left and right direction. The pachinko sphere P guided by the lower surface of the portion 59 is guided downward (bottom surface 44b side). Therefore, even if the pachinko balls P overlap vertically, the upper pachinko balls P are guided downward, and the pachinko balls P are leveled in one step. Further, as shown in FIG. 9, the separation interval R between the upstream edge N of the inlet 53a opened at the bottom surface 44b of the ball discharge port 53 and the lower surface of the rectifying guide portion 59 is larger than one pachinko ball P and 2 It is set smaller than the number. Thereby, the pachinko balls P flowing through the tank rail 31 immediately before flowing into the ball discharge port 53 are surely arranged in one row and one stage, and a plurality of pachinko balls P are prevented from flowing into the ball discharge port 53 in a state where they overlap each other. The

  As shown in FIG. 9, the lower surfaces 65, 66 of the rectifying guide portion 59 are second upward convexly extending to the upper end of the ball outlet 53 at the downstream end of the first curved surface 65 convex downward. Since the curved surfaces 66 are formed in series, first, the pachinko sphere P that contacts the first curved surface 65 is guided downward, so that the leveling action can be surely given and one step can be achieved. Further, the traveling direction of the pachinko sphere P in contact with the second curved surface 66 is changed toward the sphere outlet 53 so that the pachinko sphere P flows quickly into the sphere outlet 53 and smoothly enters the sphere passage 54. be able to. Thereby, the occurrence of clogging at the ball discharge port 53 is reliably prevented. In other words, compared to the case where the lower surface of the rectifying guide portion 59 is linearly inclined at a constant angle, the curved surface 65, 66 having a different convex direction is combined to flow on the bottom surface 44b. A leveling action and a guiding action to the ball discharge port 53 can be surely given to the pachinko ball P, and the pachinko ball P can be smoothly flowed into the ball discharge port 53.

  Further, as shown in FIG. 9, a guide surface 56 is formed that curves from the upstream edge N of the inlet 53a of the ball outlet 53 that opens at the bottom 44b on the downstream side of the tank rail 31 to the outlet 53b. The pachinko ball P flowing on the bottom surface 44 b smoothly enters the ball discharge port 53 through the guide surface 56. Further, since the guide surface 56 is curved so as to substantially follow the second curved surface 66 formed in the extension guide portion 67, the pachinko ball P is further reduced by the guide surface 56 and the second curved surface 66. The ball passes through the ball outlet 53 smoothly. Moreover, by forming the notch 60a in the right side wall 60, the opening size on the outlet side of the ball discharge port 53 is made larger than the minimum separation interval between the guide surface 56 and the extended guide portion 67. The pachinko ball P that has passed through between the guide surface 56 and the extended guide portion 67 falls freely without receiving a great resistance by the right side wall 60 or the guide surface 56 and smoothly enters the ball passage 54. That is, the leading pachinko ball P smoothly flows into the ball discharge port 53 at the downstream end of the tank rail 31 and enters the ball passage 54 from the inlet 54a, so that the flow of the subsequent pachinko ball P is not hindered. Further, the ball clogging at the ball discharge port 53 can be prevented more reliably.

  The rectifying guide portion 59 is located on the upstream side of the right side wall 60 that defines the downstream end of the tank rail 31, and at the extension guide portion 67 and the ball discharge port 53 provided at the downstream end of the rectifying guide portion 59. Since the gap with the guide surface 56 is set to a size that allows one pachinko ball P to pass therethrough, the pachinko ball that flows down the tank rail 31 while allowing the pachinko ball P to flow into the ball discharge port 53. P can be prevented from directly hitting the right side wall 60, and the right side wall 60 can be prevented from being worn or damaged. That is, as shown in FIG. 9, the pachinko sphere P falling on the extension guide portion 67 above the ball discharge port 53 falls on the ball path before hitting the right side wall 60 extending below the extension guide portion 67. 54. In addition, the vertical spacing L between the lower end of the extending guide portion 67 and the outlet 53b of the ball discharge port 53 is set to be shorter than that of one pachinko ball P, and on the right side wall 60 to the downstream side of the bottom surface 44b. Since the notch 60a is formed in the part below the extended line T, it is possible to further prevent the pachinko ball P falling away from the extending guide 67 from hitting the right side wall 60. Further, since the rectifying member 57 is configured to be attachable to and detachable from the ball storage portion 27, when the rectifying guide portion 59 is worn or damaged due to contact with the pachinko ball P, only the rectifying member 57 is replaced. By doing so, it is possible to cope with it, and it is possible to keep the cost related to replacement low.

  Since the upper opening of the tank rail 31 that extends from the downstream end of the sphere leveling area 45 to the upper side of the sphere discharge port 53 is covered with the lid portion 58 of the rectifying member 57, dust or the like The entry into the discharge port 53 can be prevented. Thereby, the smooth flow of the pachinko sphere P rectified in the sphere leveling region 45 can be maintained, and the occurrence of clogging due to dust can be prevented. Further, as shown in FIG. 3, the lid 58 is set so as not to cover the upper part of the sphere leveling area 45, so that the pachinko that flows from the sphere tank 30 to the sphere leveling area 45 in a multistage state. When the pachinko sphere P on the upper side of the sphere P is in contact with the lid portion 58, the rectifying action in the sphere leveling region 45 is not hindered, and reliable rectification in the sphere leveling region 45 is achieved.
