A payout structure that transports in the axial direction of the spiral and separates the balls taken from the gap between the outer periphery of the spiral and the payout accommodating portion one by one from the payout accommodating portion; A rectifying unit disposed above the payout receiving unit, the rectifying unit disposed in the ball storage unit so that the rectifying unit covers the payout receiving unit, the rectifying structure, and the spiral body e Bei the overflow port formed between the peripheral wall of the sphere reservoir disposed on the downstream side in the conveying direction of the ball by the not incorporated in the spiral sphere via the overflow outlet The main feature is that it is discharged onto the rectifying structure. The rectifying structure includes a rectifying unit having a triangular shape in plan view disposed above the dispensing housing unit, and the apex angle portion of the rectifying unit is disposed on the upstream side in the conveying direction of the sphere by the spiral, and the two bottoms of the rectifying unit The corner is arranged downstream in the direction of transport of the sphere by the spiral, or the main body between the two bottom corners and the apex of the rectifying unit is located upstream from the downstream in the direction of transport of the sphere by the spiral. Is formed on a slope with a downward slope as it goes to, or is formed on a slope with an upward slope as the apex angle portion of the rectifying part goes from the downstream side to the upstream side in the direction of carrying the sphere by the spiral, or In the rectifying unit, the flow rate adjusting unit protrudes downward from the rectifying unit and is provided in an inclined form gradually going inward as it goes from the two bottom corners to the apex corner, or by a spiral body Function to separate spheres one by one Rotation direction of the payout structure on the upstream side of the sphere conveyance direction by the spiral of the sphere take-up gap without providing a sphere guide protrusion for hindrance on the downstream side of the sphere take-up gap by the spiral of the sphere take-up gap Is located on the bite side or on both sides and is provided with the upper part of the payout structure open, and a space for prohibiting the entry of the ball is provided between the ball guide protrusion and the payout structure, or the ball guide protrusion May be formed on an inclined surface having a downward slope as it goes from the upstream side to the downstream side in the direction in which the sphere is transported by the spiral body of the sphere take-in gap.

  The ball payout device for a gaming machine according to the present invention is configured such that the rectifying structure is installed so as to partition the space above the payout receiving unit in the ball storage unit vertically, so that a large number of balls are above the rectifying structure. From the bottom of the rectifying structure, the ball that has moved under the rectifying structure and moved in the conveying direction without entering the spiral Since it recirculates so that it is discharged onto the rectifying structure via, it is possible to reduce the burden applied to the payout structure from the sphere of the sphere storage part, and it is possible to prevent clogging of the sphere There are advantages. The rectifying structure includes a rectifying unit having a triangular shape in plan view disposed above the dispensing housing unit, and the apex angle portion of the rectifying unit is disposed on the upstream side in the conveying direction of the sphere by the spiral, and the two bottoms of the rectifying unit If the corner portion is arranged downstream in the direction of transport of the sphere by the spiral body, the rectifying unit separates the sphere from the sphere storage unit toward the payout storage unit, so that the load applied to the rectification unit from the sphere of the sphere storage unit There is an advantage that can be reduced. If the main body portion between the two bottom corner portions and the top corner portion of the rectifying portion is formed on a slope having a downward slope from the downstream side to the upstream side in the conveying direction of the sphere by the spiral, From this, there is an advantage that the return of the sphere discharged onto the main body through the overflow port is performed more appropriately. If the apex angle part of the rectifying part is formed on an inclined surface that rises upward from the downstream side in the direction of transport of the sphere by the spiral, the apex angle part flows down from the sphere storage part toward the dispensing storage part. Therefore, there is an advantage that it is possible to reduce a burden applied to the rectifying unit from the sphere of the sphere storage unit. If the flow rate adjustment unit is provided in the rectification unit so as to protrude downward from the rectification unit and be gradually inclined inward as it goes from the two bottom corners to the top corner, the flow adjustment unit flows. The sphere that is blocked by the helix is guided obliquely from the downstream side to the upstream side in the conveying direction of the sphere, and the sphere guided by the flow rate adjusting unit flows to the end side near the payout accommodating unit in the flow rate adjusting unit. Since the spiral ball is pushed back from the downstream side in the conveying direction of the sphere, the flow rate adjusting unit adjusts the amount of the sphere flowing into the payout receiving unit so that a large amount of balls do not concentrate on the payout receiving unit from the ball storage unit. There is an advantage that can be. The ball guiding projection for inhibiting the function of separating the spheres by the helical body one by one is not provided on the downstream side in the conveying direction of the sphere by the helical body of the spherical taking-in gap, and the sphere is conveyed by the helical body of the spherical taking-in gap. Is located on the biting side or both sides in the rotational direction of the payout structure on the upstream side of the direction, and is provided with the upper part of the payout structure open, and prohibits the entry of the ball between the ball guiding protrusion and the payout structure. If the gap is provided, the spiral at the upper part of the payout structure released from the ball guide protrusion leveles the sphere of the sphere storage portion, so that the ball smoothing function by the payout structure can be secured, and the ball guide protrusion is the sphere. This prevents the ball storage part from entering the upstream side of the ball take-in clearance, so that the load applied to the payout structure from the ball in the ball storage part can be reduced, and the ball take-in without the ball guide protrusion is provided. On the downstream side of the gap, There is an advantage that the balls are properly paid out are separated one by one by the spiral enters the sphere taking the clearance dispensing housing portion. If the upper surface of the sphere guide protrusion is formed on a slope inclined downward as it goes from the upstream side to the downstream side of the sphere transport direction by the spiral of the sphere intake gap, There is an advantage that it can be reliably supplied to the downstream side.

  With reference to FIG. 2, the structure which provides the rectification | straightening structure 11 in the bulb | ball storage part 3 is demonstrated. As shown in FIG. 2 a, the ball storage portion 3 is provided with a pair of hooked portions 4 and guide portions 5 that are separated from the payout storage portion 6 in the front-rear direction. The hooked portion 4 is a portion for fixing the rectifying structure 11 to the sphere storage portion 3, a portion where the bottom wall 7 and the front wall 8 of the sphere storage portion 3 are connected to each other, and a sphere storage A portion of the bottom wall 7 and the rear wall 9 of the portion 3 that are connected to each other is provided as a through hole in the vertical direction. The guide unit 5 is a part for guiding the rectifying structure 11 to the sphere storage unit 3 in cooperation with the right wall 10 of the sphere storage unit 3. The guide unit 5 is connected to the sphere storage unit 3 from the front wall 8 and the rear wall 9. It is provided on the front wall 8 and the rear wall 9 as a vertically long protrusion protruding inside. The bottom surface of the bottom wall 7 that comes into contact with the sphere forms an inclined surface in which the sphere flows from the periphery of the sphere storage portion 3 toward the dispensing housing portion 6.

  The rectifying structure 11 includes a pair of support parts 12, a rectifying part 13, and a pair of flow rate adjusting parts 14. The support portion 12 is configured as a plate-like member that is relatively bent in the front-rear direction. The support portion 12 is provided with a latching portion 15. The latching portion 15 includes an elastic piece 16 and a flange portion 17. The elastic piece 16 is a vertically long strip that is left between a pair of separation grooves 18 formed in the lower part of the support part 12, and the upper part of the elastic piece 16 is connected to the support part 12. It is the shape. The flange portion 17 projects outward from the lower portion of the elastic piece 16. The rectifying unit 13 is configured as a plate-like member having a substantially isosceles triangular shape in plan view. The two bottom corners 19 of the rectifying unit 13 are arranged in the front-rear direction and are coupled to the inner surfaces of the pair of support units 12 facing each other. One apex angle portion 20 of the rectifying portion 13 protrudes to the left side from the support portion 12 and has a slope that gradually increases as it goes from the main body portion 21 side excluding the apex angle portion 20 of the rectifying portion 13 to the left side. Form. The main body portion 21 forms an inclined surface that gradually becomes downwardly descending from the bottom side of the rectifying unit 13 toward the apex angle portion 20 side. The flow rate adjusting unit 14 is configured as a plate-like member that protrudes downward from the rectifying unit 13 and enters from the oblique side of the bottom corner 19 of the rectifying unit 13 to the lower side of the main body 21.

  The rectifying structure 11 is attached to the sphere storage unit 3 as follows. An isosceles triangle shape of the rectifying unit 13 so that the apex angle portion 20 has an ascending slope from the main body portion 21 side to the left side and the main body portion 21 has an inclining slope from the base side to the apex angle portion 20 side. The plate surface is directed to the bottom wall 7 side. In this state, the pair of support parts 12 are inserted between the front wall 8 and the rear wall 9 from above the ball storage part 3. Accordingly, the flange portion 17 is pushed inward by the inner surface of the front wall 8 and the inner surface of the rear wall 9, and the elastic piece 16 bends inward. Thereafter, when the insertion of the support portion 12 between the front wall 8 and the rear wall 9 proceeds downward, the support portion 12 is inserted between the right wall 10 and the guide portion 5 of the ball storage portion 3 and The wall 10 and the guide part 5 are contacted. Further, when the insertion of the pair of support portions 12 between the front wall 8 and the rear wall 9 proceeds downward, and the flange portion 17 encounters the hooked portion 4, the elastic piece 16 is restored to the outside, and the flange The part 17 is fitted into the latched part 4 and latched. Thus, as shown in FIG. 2b, the overflow port 22 is formed as a vertical through hole surrounded by the right wall 10, the bottom of the rectification unit 13 and the support unit 12, and the rectification unit 13 is The rectifying structure 11 is attached to the ball storage unit 3 so as to cover the payout storage unit 6 away from the payout storage unit 6. Since the rectifying structure 11 is detachably attached to the ball storage unit 3 by the hooked portion 4 and the hooking portion 15, the rectifying structure 11 can be easily replaced, or the rectifying structure 11 can be removed and accommodated. There is an advantage that the portion 6 can be cleaned.

  A structure when the rectifying structure 11 is attached to the sphere storage unit 3 will be described with reference to FIG. As shown in FIG. 1 a, the apex portion 20 protrudes to the left of the payout receiving portion 6, the main body portion 21 covers the upper portion of the payout receiving portion 6, and the flow rate adjusting portion 14 is front and rear than the payout receiving portion 6. Arranged in the direction. And the flow volume adjustment part 14 becomes a diagonal form which goes to the inner side which is the discharge | emission accommodating part 6 side from the side of the front wall 8 or the rear wall 9 gradually as it goes to the left side from the right side. Therefore, in the sphere storage unit 3, the flow rate adjustment unit 14 blocks the flow of the sphere P flowing from the left side to the right wall 10 side with respect to the flow rate adjustment unit 14, so that the sphere that flows into the dispensing housing unit 6 from the right wall 10 side. There is an advantage that the amount of P can be reduced. The sphere P whose flow is blocked is guided obliquely from the right side to the left side by the flow rate adjusting unit 14, and the sphere P flowing from the left side to the end side of the flow rate adjusting unit 14 close to the dispensing housing unit 6 from the left side. Since it pushes to the left side, the amount of the sphere P flowing into the dispensing housing unit 6 from the left side rather than the flow rate adjusting unit 14 is adjusted so that a large amount of balls do not concentrate on the dispensing housing unit 6 from the left side than the flow rate adjusting unit 14. There is an advantage that can be. The rectifying structure 11 includes a rectifying unit 13 having a triangular shape in plan view disposed above the dispensing housing unit 6, and the apex portion 20 is disposed on the upstream side in the conveying direction indicated by the arrow X <b> 1 of the sphere by the spiral body 48, Since the two bottom corners 19 are arranged on the downstream side in the conveying direction indicated by the arrow X1 of the sphere by the spiral body 48, the rectifying unit 13 is separated so as to cut the sphere from the sphere storage unit 3 toward the payout storage unit 6, There exists an advantage that the burden added to the rectification | straightening part 13 from the bulb | ball of the bulb | ball storage part 3 can be reduced. Since the rectification unit 13 has an isosceles triangle shape in plan view, the spheres of the sphere storage unit 3 uniformly act on the rectification unit 13 from the front and rear directions, and thus the rectification structure 11 to the sphere storage unit 3. There is an advantage that the installation posture can be stabilized.

  As shown in FIG. 1 b, the main body portion 21 forms an inclined surface that gradually descends from the right side to the left side at the upper portion of the dispensing housing portion, and the apex angle portion 20 is above the bottom wall 7. In this case, a slope that gradually rises from the right side to the left side is formed. The apex angle portion 20 is parallel to the center portion of the bottom wall 7 in the front-rear direction. The gap between the apex portion 20 and the bottom wall 7 is configured such that a plurality of spheres can pass adjacent to each other in the front-rear direction, but the plurality of spheres are stacked vertically and cannot pass. Therefore, in the ball storage unit 3, the rectifying structure 11 partitions the space above the dispensing housing unit 6 in the vertical direction, so that a large amount of spheres do not concentrate on the dispensing housing unit 6 from above the rectifying structure 11. There is an advantage that you can. The sphere that has flowed down the bottom wall 7 from the left side of the payout accommodating portion 6 toward the payout accommodating portion 6 passes between the apex portion 20 and the bottom wall 7 as indicated by the arrow X2, or at the arrow X3. It passes over the apex portion 20 as shown. Since the apex portion 20 is formed on an inclined surface having an upward slope as it goes from the downstream side in the transport direction indicated by the arrow X1 of the sphere by the spiral body 48 to the upstream side, the apex portion 20 is the bottom wall 7 of the sphere storage unit 3. Since the sphere that has flowed down from the sphere storage portion 6 to the dispensing housing portion 6 is separated so as to be divided into an upper corner portion 20 and a lower portion without countering the flow of the bottom wall 7, the load applied to the rectifying portion 13 from the sphere of the sphere storage portion 3 There is an advantage that can be reduced. The sphere that has passed between the apex corner 20 and the bottom wall 7 as indicated by the arrow X2 is carried in the conveying direction indicated by the arrow X1 of the sphere by the spiral body 48 of the payout accommodating portion 6. The sphere that has moved in the transport direction indicated by the arrow X1 without being taken into the spiral 48 passes under the rectifying unit 13 and is guided upward by the ridge 32 as indicated by the arrow X4. 22 is passed upwards. The sphere that has passed through the overflow port 22 flows down on the main body portion 21 toward the apex portion 20 as indicated by an arrow X5.

  In short, since the rectifying structure 11 is installed so as to divide the space above the dispensing housing portion 6 in the vertical direction, a large amount of balls are concentrated directly on the dispensing housing portion 6 from above the rectifying structure 11. The sphere that has entered the conveying direction indicated by the arrow X1 without entering the spiral body 48 and diving under the rectifying section 13 is moved from the bottom of the rectifying section 13 via the overflow port 22. It recirculates such that it is discharged onto the rectifying unit 13. Thereby, there is an advantage that it is possible to reduce the burden applied to the payout structure 44 from the sphere of the sphere storage unit 3 and to prevent the clogging of the sphere from occurring. Since the main body portion 21 is formed on a slope having a downward slope as it goes from the downstream side in the conveying direction indicated by the arrow X1 of the sphere by the spiral body 48 to the upstream side, the path of the sphere indicated by the arrow X4; X5 is created. There is an advantage that the reflux of the sphere discharged from the bottom of the part 21 onto the main body part 21 via the overflow port 22 is more appropriately performed.

  Matters that gradually increase as the apex portion 20 moves to the left side from the main body 21, matters that gradually decrease as the main body portion 21 moves from the right side to the left side, and the overflow port 22 corresponds to the right wall 10. The matter formed between the rectifying units 13 is when the conveying direction indicated by the arrow X1 of the sphere by the spiral 48 is from the left side to the right side. When the conveyance direction indicated by the arrow X1 of the sphere by the spiral body 48 is reversed from the right side to the left side, the apex angle portion 20 gradually rises as it goes from the main body portion 21 to the right side, and the main body portion 21 moves to the left side. From the left side to the right side, the slope gradually decreases, and the overflow port 22 is formed between the left wall 38 (see FIG. 4) and the rectifying unit 13. That is, the apex angle portion 20 gradually increases as it goes in the opposite direction of the conveyance direction indicated by the arrow X1 of the sphere by the spiral body 48, and the main body portion 21 is reverse in the conveyance direction indicated by the arrow X1 of the sphere by the spiral body 48. The overflow port 22 is formed between the rectifying unit 13 and the peripheral wall of the ball storage unit 3 arranged on the downstream side in the conveying direction indicated by the arrow X1 of the ball by the spiral body 48. The

The mechanism attachment portion 28 is configured as a cylindrical shape protruding rightward from the right wall 10 of the ball storage portion 3. The upper opening 29 is a form in which the entire portion corresponding to the right wall 10 of the payout receiving portion 6 is removed, and the balls are placed one by one before and after the payout structure 44 when the payout structure 44 is inserted. A ball outlet to be supplied to the payout mechanism 41 from the payout accommodating portion 6 is formed. The lower opening 30 is configured as a through hole in the left-right direction so as to take in the payout ball detector 46. The bottom wall 7 of the ball storage unit 3 is provided with a payout storage unit 6, a supply port 31, and a basket 32. The supply port 31 is located in the center part of the front-back direction on the right side of the bulb | ball storage part 3, is a planar view rectangle long in the left-right direction, and comprises the through-hole to an up-down direction. The payout storage unit 6 is formed in a shape surrounding a space recessed downward from the supply port 31. The cage 32 closes the right side of the supply port 31 in the dispensing storage unit 6 and stores the sphere so that the sphere stored in the sphere storage unit 3 does not interfere with the sphere taken into the dispensing structure 44 and reaching the right side. The inflow of the sphere from the portion 3 to the payout accommodating portion 6 is prevented (see FIG. 6).

  A substrate accommodating portion 33 is provided in front of the sphere storage portion 3. The substrate housing part 33 is configured as a box-shaped room opened upward. On the bottom wall of the substrate accommodating portion 33, the relay substrate 34 is attached from above with a set screw (not shown) such as a tapping screw.

  The payout mechanism 41 of the ball payout device 1 has a structure in which a payout motor 43, a payout structure 44, a passage switching mechanism 45, and a payout ball detector 46 are incorporated in a mechanism housing 42. The payout motor 43 is constituted by a step motor. A payout structure 44 is coaxially coupled to an output shaft such as a motor shaft of the payout motor 43. The payout structure 44 includes a round bar 47, a spiral body 48, and a shaft portion 49. The round bar 47 is a straight bar extending in the left-right direction. One end of the round bar 47 is connected to the output shaft of the dispensing motor 43 so as to rotate together. The spiral body 48 spirals outwardly in the radial direction from the outer peripheral surface of the round bar 47 at intervals separating the spheres one by one in the direction parallel to the axial center extending in the left-right direction of the round bar 47 on the outer peripheral surface of the round bar 47. Protrusively. The shaft portion 49 is provided on the left end surface of the round bar 47 so as to protrude from the round bar 47 to the left side. The passage switching mechanism 45 includes an electromagnetic solenoid 50 and a pair of valve bodies 51. When the power supply to the electromagnetic solenoid 50 is stopped, the valve body 51 rises vertically by the spring force of a spring (not shown). The gap between the valve elements 51 is configured as a ball payout passage 52, and when power is supplied to the electromagnetic solenoid 50, the valve element 51 is tilted inward against the spring force of a spring (not shown). Thus, the ball payout passage 52 is closed, and a gap outside the valve body 51 is configured as a ball removal passage 53. The mechanism housing 42 is provided with a housing mounting portion 54 as a through hole in the left-right direction.

  The ball payout device 1 is configured by assembling the tank structure 2 and the payout mechanism 41 as follows. The payout structure 44 of the payout mechanism 41 is inserted into the payout receiving portion 6 from the right outer side of the tank structure 2 via the upper opening 29, the shaft portion 49 is fitted into the bearing hole 23, and the payout ball detector 46 is lowered. The mechanism housing 42 is placed on the right side surface of the tank structure 2 through the opening 30 below the dispensing housing portion 6, and a set screw 55 such as a tapping screw is attached to the housing from the outside of the mechanism housing 42. Fastened to the mechanism mounting portion 28 via the portion 54. As a result, the payout structure 44 is arranged in the payout receiving portion 6, and the payout mechanism 41 and the tank structure 2 are assembled together to form the ball payout device 1.

  With reference to FIG. 5, the structure in the case where the payout structure 44 is arranged in the payout receiving portion 6 will be described. FIG. 5 shows a mode in which the rectifying structure 11 is not attached to the sphere storage unit 3 in order to simplify the drawing. In FIG. 5a, a ball take-in gap 56; 57 for taking in a ball from the ball storage unit 3 is provided between the pay-out receiving unit 6 and the outer peripheral surface of the round bar 47 of the pay-out structure 44. It is provided at the front and back with the body 44 as a boundary. The sphere guide protrusions 24; 25 are for inhibiting the function of separating the spheres by the spiral 48 one by one, and are downstream in the conveying direction indicated by the arrow X1 of the sphere by the spiral 48 of the sphere intake gap 56; 57. Without being provided on the side, on the upstream side in the conveying direction indicated by the arrow X1 of the ball by the spiral body 48 of the ball take-in gap 56; The upper portion of the payout structure 44 is opened without covering the upper portion of the payout structure 44. The sphere guide protrusion 24 is arranged so as to block a groove for taking in the sphere of the spiral body 48 located at the shaft portion 49 of the payout structure 44 so that the sphere cannot be taken in. The sphere guide protrusion 25 closes the two grooves adjacent to each other in the axial direction of the spiral body 48 for capturing the sphere of the spiral body 48 located at the shaft portion 49 of the payout structure 44 so that the sphere cannot be captured. Placed in. Although the length of the spiral body 48 in the axial direction increases, the number of grooves of the spiral body 48 that is blocked by the sphere guide protrusion 24 may be plural, and the number of grooves of the spiral body 48 that is blocked by the sphere guide protrusion 25 may be large. Good. However, as in the best mode, the number of grooves of the spiral body 48 that is blocked by the sphere guide protrusion 24 is one less than the number of grooves of the spiral body 48 that is blocked by the sphere guide protrusion 25. This is preferable because the length in the axial direction can be shortened.

  The length of the ball guide protrusion 25 extending from the left wall of the payout receiving portion 6 to the right is longer than the length of the ball guide protrusion 24 extending from the left wall of the payout receiving portion 6 to the right. The sphere guide protrusion 25 is longer than the sphere guide protrusion 24 when the payout structure 44 rotates in the direction of the arrow W1 shown in FIG. When the payout structure 44 pays out a sphere, the sphere guide protrusion 24 is provided to be longer than the sphere guide protrusion 25 when rotating in the direction opposite to the arrow W1. That is, the matter in which one of the ball guide protrusions 24; 25 is longer than the other is that the payout structure 44 pays out the ball when the payout structure 44 is provided on the biting side in the direction of rotation for paying out the ball. Therefore, it is set longer than the one provided on the lifting side in the rotating direction. As a result, the length in the left-right direction of the payout storage unit 6 can be formed as small as possible, and the burden applied to the payout structure 44 from the balls of the ball storage unit 3 can be reduced.

  In FIG. 5b, the height H1 of the ball guide protrusion 24 from the bottom of the payout receiving portion 6 is lower than the height H2 of the ball guide protrusion 25 from the bottom of the payout receiving portion 6 (H1 <H2). The dimension of H1 <H2 is a case where the payout structure 44 rotates in the direction of the arrow W1 when paying out the ball. In the case where the payout structure 44 pays out a ball and rotates in the direction opposite to the arrow W1, H1 is set to be higher than H2 (H1> H2).
