Description

  The present invention relates to a pachinko gaming machine provided with a ball leveling member for leveling game balls flowing down in a state where they are stacked in a tank rail.

  Generally, in a pachinko gaming machine, as shown in FIG. 12, a game ball supplied from a replenishment cage of a game island facility is received at the upper position of a back mechanism plate m mounted on the back side of the gaming machine body. A ball tank k and a tank rail a inclined downwardly with a gentle gradient to flow down the game ball released from the ball tank k are arranged, and the game ball flowing down the tank rail a is a ball path in the vertical direction. It is sent to the lower ball dispensing device f via e.

  The tank rail a is provided with a ball leveling member b for leveling the stacked game balls in order to prevent various problems caused by the game balls flowing down in the stacked state. It has been. The conventional ball leveling member b can swing in the front-rear direction by pivotally supporting the upper end of a support shaft c projecting above the tank rail a so as to be orthogonal to the flow direction of the game ball in the tank rail a. A weight d for returning the swinging sphere leveling member b to the suspended state is accommodated in the lower end portion. Then, when the game balls flow down in a state where they are stacked in the tank rail a, the ball leveling member b receives the fluid pressure of the game balls on the front side facing the game balls and rotates rearwardly. The lowermost game ball is caused to flow down from a gap corresponding to one game ball generated by the rotation between the lowermost end portion of the bottom member b and the inner bottom surface of the tank rail a, and is suspended by the weight d. By restricting the flow of the upper game ball stacked on the lowermost game ball by the return force of the ball leveling member b to be returned, the game ball flowing down in a state of being stacked in the tank rail a They are flattened (see, for example, Patent Documents 1 and 2).

In addition, as described above, the game balls flowing down the tank rail a are sent to the ball dispensing device f through the ball passage e. However, when the ball dispensing device f or the ball passage e is removed due to a failure or a maintenance check. In addition, a ball stopper member g for preventing the game ball in the tank rail a from flowing down and spilling out of the machine is disposed in the vicinity of the lower end of the tank rail a. The conventional ball stopper member g is made of a strip plate material having a substantially L-shaped cross section having a stopper piece h that is bent at a substantially right angle at the tip, and a base shaft j that is horizontally mounted on the upper portion of the tank rail a. Is pivotally supported by the shaft. Then, on the upper side of the support shaft j, the stopper piece h at the tip is inserted into the tank rail a by selectively rotating the ball stopper member g in either the forward or reverse direction with the base as a fulcrum. It is provided so that it can be converted into a ball stop position that blocks the game ball and a standby position that retreats from the tank rail a and allows the game ball to flow down (see, for example, Patent Document 3).
JP-A-8-84836 (paragraph number [0003], FIG. 5) Japanese Patent Laid-Open No. 8-243211 (paragraph number [0002], FIG. 8) JP-A-9-70476 (paragraph number [0002], FIG. 11)

  By the way, in the conventional ball leveling member b, when a large amount of game balls pile up and flow down in the tank rail a, the ball leveling member b rotates backward more than necessary due to excessive flow pressure of the game balls. As a result, the flow-down restricting action on the upper game balls cannot be obtained, and the game balls may pass through the ball leveling member b while being stacked. For this reason, the conventional ball leveling member b has a problem that it cannot always obtain a reliable and stable leveling action of the game ball.

  Further, in a pachinko gaming machine, a rectangular opening is formed at a substantially central portion of the back mechanism plate m in order to avoid interference with a control device attached in a protruding state on the back side of the game board and a protective cover of the control device. A portion n (see FIG. 12) is formed, the ball tank k and the tank rail a are disposed above the opening n, and the ball passage e and the ball dispensing device f are disposed on the side of the opening n. Is arranged. Furthermore, on the back mechanism board m, an information terminal board p (see FIG. 12) that outputs a required information signal such as a gaming state is located at an upper position of the back mechanism board m that can be easily wired to the communication device of the game island equipment. The ball tanks k are arranged side by side, and the ball stopper member g of the tank rail a is disposed below the information terminal board p. On the other hand, in recent years, the size of the game board has been increased due to the expansion of the game area and the increase in the size of the symbol display device, and the opening n of the back mechanism board m tends to be increased correspondingly. And if the opening part n of the back mechanism board m becomes large in this way, the vertical space | interval of the said tank rail a and the information terminal board p will become narrow in connection with this. Here, in the conventional ball stopper member g disposed in the vicinity of the lower end of the tank rail a, the rotation operation is performed on the upper side of the support shaft j with the base as a fulcrum. When the vertical distance between the tank rail a and the information terminal board p is reduced as described above, the operation space is reduced, and it becomes difficult to rotate the ball stopper member g, or a wiring cable connected to the information terminal board p is used. There is a problem that the stopper piece h at the front end is caught, and it is not possible to cope with the reduction of the operation space accompanying the enlargement of the opening n of the back mechanism plate m.

  The present invention has been made in order to solve such problems, and it is possible to always obtain a reliable and stable leveling action of the game ball and to reduce the operation space by expanding the opening of the back mechanism plate. It is an object of the present invention to provide a pachinko gaming machine provided with a ball leveling member that can also have a ball stopper function that can be adapted to the game.

  The present invention provides, on the back side of the gaming machine body, a ball tank that receives a game ball supplied from a supply tank of a game island facility, a downwardly inclined tank rail that flows down the game ball released from the ball tank, In a pachinko gaming machine having a ball leveling member for leveling a game ball that is stacked and flowing down in a tank rail, the front end has a sharp end, and a substantially band that slopes upward from the sharp end toward the rear side. A ball-equalizing member having a plate-like ball ride-up portion has its sharp end facing a height position where one game ball can pass with respect to the inner bottom surface of the tank rail, and in the flow-down direction of the game ball It is a pachinko gaming machine characterized by being arranged to face each other.

  Here, the ball leveling member can be arranged in the predetermined manner by pivotally supporting the ball leveling member on a support shaft protruding from the back side of the gaming machine main body. The distance between the sharp end of the ball leveling member and the inner bottom surface of the tank rail is slightly larger than the diameter of the game ball so that the lowermost game ball rolling on the inner bottom surface of the tank rail can easily pass through. It is preferable to set.

  In the above-described configuration, a configuration is proposed in which an arcuate return surface portion that is curved upward is provided at the upper end portion of the ball ride-up portion to send back the game ball that has been picked up from the sharp end.

  Further, in the above-mentioned configuration, a support shaft that pivotally supports the ball leveling member so as to be rotatable in the vertical direction, and the ball leveling member has one game ball with a sharp end with respect to the inner bottom surface of the tank rail. Position holding means for holding at a spherical leveling position facing a height position where it can pass through, and the spherical leveling member is rotated downward by releasing the holding of the position holding means, and the sharp end thereof is a tank rail. A configuration is proposed in which the ball is positioned at a ball stop position that abuts the inner bottom surface of the ball and blocks the flow of the game ball.

  Further, the position holding means includes a key groove formed so as to face the inner peripheral surface of the shaft insertion hole formed in the spherical member and the outer peripheral surface of the support shaft inserted through the shaft insertion hole. There is proposed a configuration including a pair and a key member that is removably inserted into the key groove pair.

  As described above, the present invention has a sharpening end at the front end, and a ball leveling member having a substantially strip-shaped ball riding portion that is inclined upward from the sharp end toward the rear side. The game ball is disposed in the tank rail so that it faces a height position that allows one game ball to pass through the inner bottom surface of the tank rail and is opposed to the flow direction of the game ball. When the ball leveling member flows down to the position where the ball leveling member is disposed, the lowermost game ball passes through the gap formed between the sharp end of the leveling member and the inner bottom surface of the tank rail. On the other hand, the upper game balls stacked on the lowermost game balls ride on the ball ride-up portion from the sharp end of the ball leveling member and are separated from the lowermost game balls. Here, the game ball riding on the ball riding section is pushed upward by the flow pressure of the subsequent game ball, but the game on the ball riding section is caused by the upward inclination of the ball riding section. When a force to descend downward is generated in the ball, and the force to descend and the force to push up are balanced, the ball stops on the ball climbing portion. When the stacked state of the game balls flowing down to the position where the ball leveling member is disposed in the tank rail is eliminated and the force for pushing up the game balls on the ball riding section disappears, the game rides on the ball riding section. The game ball descends by its own weight, merges with the lowermost game ball, and flows down through the gap formed between the sharp end and the inner bottom surface of the tank rail. Thereby, it is possible to level the game balls flowing down in a state where the tank rails are stacked. As described above, in the present invention, unlike the conventional swing-type sphere-equalizing member b (see FIG. 12), the sphere-equalizing member is fixedly disposed, and the sharp end of the sphere-equalizing member is provided. The gap for one game ball generated between the tank rail and the inner bottom surface of the tank rail does not fluctuate, so that it is possible to always obtain a reliable and stable leveling action of the game balls.

  In addition, in the configuration in which an arcuate return surface portion that is curved upward to send back the game ball riding up from the sharp end is provided at the upper end portion of the ball riding-up portion, the subsequent game ball pushed up on the ball riding-up portion is pushed up When the game ball has a strong fluid pressure and the game ball is pushed up to the upper end of the ball ride-up part, the arc is turned upside down by an arcuate return surface provided at the upper end. Can be sent back sequentially. As a result, the game ball that has reached the upper end of the ball ride-up portion passes through the upper end and does not fall down or is blocked by the upper end to prevent the subsequent game ball from being hindered. The upper game balls separated from the other game balls can be appropriately processed.

  Further, a support shaft that pivotally supports the ball leveling member so as to be rotatable in the vertical direction, and a height at which the sharpening end of the ball leveling member can pass one game ball with respect to the inner bottom surface of the tank rail. Position holding means for holding at a sphere leveling position facing the position, and the sphere leveling member rotates downward by releasing the holding of the position holding means, and its sharp end abuts against the inner bottom surface of the tank rail. In the configuration that is positioned at the ball stop position that blocks the flow of the game ball, the ball leveling member is always held at the ball leveling position by the position holding means as described above. While it is possible to obtain a reliable and stable leveling action of the game ball, the ball leveling member is disposed in the tank rail when the ball leveling member is positioned at the ball stop position by releasing the holding of the position holding means. The game ball flowing down to the position is the tip of the ball leveling member. It will be rides on ball riding section from the end, whereby it is blocked gaming ball that flows down is interrupted. Therefore, when the ball dispensing device or the ball passage is removed due to a failure or a maintenance check, a ball stopper action is produced by positioning the ball leveling member at the ball stopper position via the holding release operation of the position holding means. Can do. In particular, in the ball leveling member of this configuration, the sharp edge from the height position at which one gaming ball can pass through the inner bottom surface of the tank rail to the position where it abuts on the inner bottom surface of the tank rail. Therefore, the rotation distance is small compared with the conventional one that rotates on the upper part of the support shaft with the base as a fulcrum. Therefore, it is possible to cope with a reduction in the operation space associated with the enlargement of the opening of the.

  Further, the position holding means includes a key groove formed so as to face the inner peripheral surface of the shaft insertion hole formed in the spherical member and the outer peripheral surface of the support shaft inserted through the shaft insertion hole. In a configuration comprising a pair and a key member that is removably inserted into the key groove pair, the spherical member is fitted into the spherical member by inserting the key member into the opposing key groove pair. On the other hand, it can be held in a non-rotatable position, while by pulling out the key member fitted in the key groove pair, the sphere leveling member pivotally supported on the support shaft can be rotated, It can be easily rotated to the stop position.

Below, the 1st Example of this invention is described based on FIGS.

It is pivotally attached. A game board 8 having a game area defined by a substantially circular rail 7 is attached to the front frame 6 in a state where the game board 8 is fitted in the opening 5. A glass door 10 covering 8 and an upper tray panel 12 provided with an upper tray 11 are pivotally supported so as to be openable and closable. A lower tray 13 is formed integrally with the lower portion of the front frame 6 so as to be positioned below the upper tray 11, and a firing handle 14 is disposed on the right side of the lower tray 13. Although not shown in the drawing, in the game area of the game board 8, various game members such as a symbol display device, a big prize opening, an electric accessory, a game nail, and a windmill are arranged at predetermined positions.

  On the other hand, a back mechanism plate 15 (see FIG. 3) is provided on the back side of the gaming machine main body 3 so as to be in contact with the back side of the game board 8. One side edge of the back mechanism plate 15 is pivotally connected to the back side edge portion of the front frame 6 via hinge members 16, 16. As shown in FIG. 3, the back mechanism plate 15 is provided with a ball tank 17 at the upper portion thereof, and a game ball supplied from a supply tank of a game island facility (not shown) through a flexible pipe It can be received in the ball tank 17. In addition, the back mechanism plate 15 includes a tank rail 19 inclined downwardly with a gentle slope for receiving and flowing a game ball released from a ball outlet 18 opened in the bottom wall of the ball tank 17, and a lower end of the tank rail 19. A ball path 21 in the vertical direction is provided that communicates with the unit and guides the game ball to the lower ball payout device 20. Further, the back mechanism plate 15 is provided with bifurcated dispensing channels 22a and 22b for guiding the game balls dispensed from the ball dispensing device 20 further downward, one of the dispensing channels 22a being The ball outlet 23 of the upper tray 11 communicates with the ball outlet 23, and the other discharge channel 22 b communicates with the ball outlet 24 of the lower tray 13. The tank rail 19, the ball passage 21, and the payout passages 22a and 22b are made of light-transmitting synthetic resin so that a game ball flowing down inside can be seen.

  In addition, the back mechanism plate 15 has a substantially central portion in order to avoid interference with a control device attached to the back side of the game board 8 and a protective cover of the control device (both not shown). A rectangular opening 25 is formed, the tank rail 19 is disposed above the opening 25, and the ball passage 21 and the ball dispensing device 20 are disposed on the side of the opening 25. Yes. Further, an information terminal board 26 for outputting a required information signal such as a game state is arranged next to the ball tank 17 at an upper position of the back mechanism plate 15.

  A ball stopper member 27 is disposed in the vicinity of the lower end of the tank rail 19 located below the information terminal board 26. The ball stopper member 27 is the same as the conventional structure, and is formed of a strip plate member having a substantially L-shaped cross section provided with a stopper piece 28 bent at a substantially right angle at the tip, and a base portion thereof is an upper portion of the tank rail 19. Is pivotally supported by a support shaft 29 that is mounted horizontally. Then, on the upper side of the support shaft 29, the stopper piece 28 at the tip is inserted into the tank rail 19 by selectively rotating the ball stopper member 27 in either the forward or reverse direction with the base as a fulcrum. Thus, it can be converted into a ball stop position for blocking the game ball and a standby position for retreating from the tank rail 19 and allowing the game ball to flow down. As a result, when the ball dispensing device 20 or the ball passage 21 is removed due to a failure, maintenance inspection, or the like, the ball stopper member 27 is converted into a ball stopping position to block the game ball, thereby The game ball is prevented from spilling out of the machine.

Next, the main part of the present invention will be described.
As shown in FIG. 6, the tank rail 19 is formed in a substantially U-shaped cross section by a bottom wall portion 30 and front and rear side wall portions 31 a and 31 b, and a partition wall standing on the bottom wall portion 30 in the inside thereof. Two ball flow paths 33 and 33 are defined by the section 32. Each of the lateral widths of the ball passages 33 and 33 is set to be slightly wider than the diameter size of the game ball x, so that the game balls x can flow down in a line. Further, at a substantially intermediate position in the longitudinal direction of the tank rail 19, a spherical leveling member 36A (see FIG. 3) described later according to the main part of the present invention is disposed. The side wall portion 31b on the upstream side of the ball leveling member 36A is extended upward to a predetermined height position, and the side portion on the back side of the tank rail 19 is shielded by the side wall portion 31b. Even if it flows down in a stacked state, it does not spill from the tank rail 19.

  As shown in FIG. 4, the sphere leveling member 36A has a sharp end 37 at the front end and a substantially strip-shaped ball riding portion 38 that is inclined upward from the sharp end 37 toward the rear side. The sharp end 37 is disposed so as to face a height position where one game ball x can pass through the inner bottom surface 34 of the tank rail 19 and face the flow direction of the game ball x. ing.

  Here, as shown in FIG. 5 (a), a support shaft 39 formed in a deformed cross section such as a substantially octagonal cross section is provided on the back mechanism plate 15 at a predetermined height position on the tank rail 19. Further, a shaft insertion hole 40 is formed in the rear end portion of the sphere leveling member 36A so as to match the deformed cross-sectional shape of the support shaft 39 in the width direction. Yes. Then, by fitting the shaft insertion hole 40 and the support shaft 39, the sphere leveling member 36 </ b> A cannot rotate with respect to the support shaft 39 through the anti-rotation action caused by the mutual fitting of the deformed cross sections. Is pivotally supported. Further, in this state, as shown in FIGS. 5B and 6, the shaft insertion hole 40 is screwed by screwing a fixing bolt 55 having a retaining collar portion 56 from the end portion of the support shaft 39. The ball leveling member 36 </ b> A is fixed to the support shaft 39 through the pressing action of the retaining collar 56 that contacts the edge surface of the hole. Further, a spacer portion 41 having a diameter slightly larger than a portion fitted to the shaft insertion hole 40 of the sphere leveling member 36A is provided at the base portion of the support shaft 39, and the sphere leveling member is formed by the spacer portion 41. 36A is positioned at a predetermined position on the support shaft 39.

  In the ball climbing portion 38 of the sphere leveling member 36A, a single slit 42 is formed at a position corresponding to the partition wall portion 32 of the tank rail 19 from the sharp end 37 to the vicinity of the rear upper end. By avoiding interference with the partition wall portion 32 of the tank rail 19 by 42, the sharpened end 37 can be brought to a predetermined height position with respect to the inner bottom surface 34 of the tank rail 19.

  In addition, an arc-shaped return surface portion 43 that is curved continuously upward from the upper surface of the ball riding portion 38 is provided at the upper end portion of the ball riding portion 38, and rides on the ball riding portion 38 from the sharp end 37. The game ball can be sent back by being reversed so as to draw an arc by the arcuate return surface portion 43.

  In such a configuration, when the game ball x flows down without being stacked in the tank rail 19, as shown in FIG. 7A, the sharp end 37 of the ball leveling member 36A and the tank rail 19 Since the game ball x passes through the gap between the inner bottom surface 34 and the inner bottom surface 34 without hindrance, the game ball x can smoothly flow down to the downstream side. Further, when the game ball x has flowed down to the position where the ball leveling member 36A is disposed in a state of being stacked in the tank rail 19, as shown in FIG. 7B, the sharpness of the ball leveling member 36A is sharpened. The lowermost game ball x flows down through the gap formed between the end 37 and the inner bottom surface 34 of the tank rail 19, while the upper game ball x stacked on the lowermost game ball x The ball leveling member 36A rides on the ball riding portion 38 from the sharp end 37 and is separated from the lowermost game ball x. Here, the game ball x riding on the ball climbing portion 38 is pushed upward by the fluid pressure of the subsequent game ball x, but the ball climbing portion 38 is inclined upward, When a force to descend downward is generated in the game ball x on the riding part 38 and the force to descend and the pushing force are balanced, the game ball x stops on the ball riding part 38. When the stacked state of the game balls x flowing down to the position where the ball leveling member 36A is disposed in the tank rail 19 is eliminated and the force for pushing up the game balls x on the ball riding-up portion 38 disappears, The game ball x riding on the ride-up section 38 descends by its own weight, merges with the lowermost game ball x, and passes through the gap formed between the sharp end 37 and the inner bottom surface 34 of the tank rail 19. Will flow down. Thereby, the game balls x flowing down in a state where the tank rails 19 are stacked can be leveled. In this way, the ball leveling member 36A is fixedly disposed, and one game ball generated between the sharp end 37 of the ball leveling member 36A and the inner bottom surface 34 of the tank rail 19 is provided. Since the gap does not vary, it is possible to always obtain a reliable and stable leveling action of the game ball x.

  Further, the upper end portion of the ball riding portion 38 is provided with an arcuate return surface portion 43 that is curved upward to send back the game ball x riding from the sharp end 37, so that the game ball x riding on the ball riding portion 38 is provided. When the subsequent game ball x that pushes upward is strong and the game ball x is pushed up to the upper end of the ball riding-up portion 38, the arc-shaped return surface 43 provided at the upper end causes the game ball As shown in FIG. 7C, x can be reversed and sent back sequentially in an arc. As a result, the game ball x that has reached the upper end portion of the ball riding-up portion 38 does not pass through the upper end portion and spills over, or is blocked by the upper end portion and does not prevent the subsequent game ball x from being ridden. The upper game ball x separated from the lowermost game ball x can be properly processed.

In the second embodiment, a spherical leveling member 36B pivotally supported so as to be pivotable in the vertical direction is provided, and a sharp end 37 of the tank rail 19 is provided by a position holding means. The ball leveling member 36B is held at a ball leveling position (see FIG. 8A) that faces a height position where one game ball can pass through the inner bottom surface 34, and the position holding means is released to hold the ball leveling member 36B. By rotating downward, the sharpened end 37 is positioned at a ball stop position (see FIG. 8B) where it abuts against the inner bottom surface 34 of the tank rail 19 and blocks the flow of the game ball. In the second embodiment, the ball stopper member 27 (see FIG. 3) in the first embodiment described above is removed.

  As shown in FIG. 9, the back mechanism plate 15 is provided with a cylindrical support shaft 44 that pivotally supports a spherical leveling member 36 </ b> B at a predetermined height above the tank rail 19. Projecting perpendicularly to the longitudinal direction, the outer circumferential surface of the support shaft 44 is formed with concave groove-like key grooves 45 along the axial direction at the vertical position thereof. Further, an insertion hole 46 through which a connecting shaft 53 of an operation member 51 described later is inserted is provided in the center portion of the support shaft 44 along the axial direction. On the other hand, a shaft insertion hole 47 having a circular cross-section through which the support shaft 44 is inserted is provided in the rear end portion of the sphere leveling member 36B in the width direction. Recessed key grooves 48 and 48 are formed at positions corresponding to the key grooves 45 and 45. Here, as shown in FIG. 10, the key grooves 48 and 48 and the key grooves 45 and 45 are formed to face each other across the inner peripheral surface of the shaft insertion hole 47 and the outer peripheral surface of the support shaft 44. Thus, keyway pairs 49 and 49 are formed. Then, by fitting the shaft insertion hole 47 and the support shaft 44, the ball leveling member 36 </ b> B is pivotally supported by the support shaft 39, and further, the key groove pair 49, 49 will be described later. By inserting the key members 50, 50, the spherical leveling member 36B is held at the spherical leveling position (see FIG. 8A). The key groove pairs 49 and 49 and the key members 50 and 50 constitute a position holding means for the spherical member 36B.

  As shown in FIG. 9, the key members 50, 50 are projected on the back surface of the operation member 51 formed in a disk shape, and are inserted into the key groove pairs 49, 49 so as to be freely inserted and removed. ing. Further, as shown in FIGS. 11A and 11B, the operation member 51 is connected to a retaining plate 52 disposed on the back surface of the back mechanism plate 15 by a connecting shaft 53. The connecting shaft 53 is inserted through the insertion hole 46 of the support shaft 44. The length of the connecting shaft 53 is such that the key members 50, 50 are completely pulled out from the key groove pairs 49, 49 as shown in FIG. In this state, the retaining plate 52 is set to a predetermined length that contacts the back surface of the back mechanism plate 15. Further, a semicircular groove 54 that facilitates the drawing operation is provided on the outer peripheral surface of the operation member 51.

  In addition, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and redundant description is omitted.

  In such a configuration, by inserting the key members 50, 50 into the opposing key groove pairs 49, 49, the sphere leveling member 36B can be held unrotatably at the sphere leveling position. In addition, in the state where the ball leveling member 36B is held at the ball leveling position by the position holding means (see FIG. 8 (a)), as described above, a reliable and stable leveling action of the game ball is always obtained. be able to. On the other hand, by pulling out the key members 50, 50 fitted in the key groove pairs 49, 49, the holding by the position holding means is released, and the sphere leveling member 36B pivotally supported by the support shaft 44 is rotatable. Thus, the ball leveling member 36 </ b> B can be rotated by its own weight to a ball stop position where the sharp end 37 contacts the inner bottom surface 34 of the tank rail 19. In this way, in a state where the ball leveling member 36B is positioned at the ball stop position by the release of the position holding means, the game ball x that has flowed down to the position where the ball leveling member 36B is disposed in the tank rail 19 However, as shown in FIG. 8B, the ball leveling member 36B rides on the ball climbing portion 38 from the sharp end 37, thereby blocking the game ball x and blocking its flow down. Therefore, when the ball dispensing device 20 or the ball passage 21 (see FIG. 3) is removed due to a failure or a maintenance check, the ball leveling member 36B is positioned at the ball stop position via the holding release operation of the position holding means. Can cause a ball stop action. In particular, in the ball leveling member 36 </ b> B having this configuration, the sharp end 37 moves from the height position at which one gaming ball can pass through the inner bottom surface 34 of the tank rail 19 to the inner bottom surface 34 of the tank rail 19. Because it rotates a small distance to the abutting position, as compared with the conventional rotating on the upper side of the support shaft as a fulcrum, the rotation distance is slightly, As a result, it is possible to cope with the reduction of the operation space accompanying the enlargement of the opening 25 of the back mechanism plate 15.
