Description

  The present invention relates to a foreign matter removing structure for removing foreign matter flowing through a game ball passage and a gaming machine installation island having a foreign matter removing structure in the game ball passage in a gaming ball passage through which a game ball flows.

  A game store where a pachinko gaming machine, which is an example of a gaming machine, is installed is provided with a gaming machine installation island for installing a plurality of pachinko gaming machines side by side. Inside the gaming machine installation island, for example, a collection basket (game ball channel, so-called dove groove) for collecting game balls discharged from a pachinko gaming machine is disposed in an inclined manner. The sphere flows down on the bottom surface and is supplied to a lifting device or the like.

  Thus, the collection basket provided on the island where the gaming machine is installed is opened upward to receive the game ball discharged from the pachinko gaming machine installed above it. In some cases, foreign matter such as nails and screws for installing and fixing electronic parts, coins, cards, or pachinko gaming machines provided in pachinko machines may be mixed.

  The foreign matter mixed in the recovery basket in this way is pushed by the game ball flowing down on the bottom surface and flows down together with the game ball, and if it enters the lifting device or the like provided on the downstream side of the recovery basket, There was a risk of causing damage or failure of the device.

  Therefore, the flow path surface of the game ball flow path such as such a collection basket is formed into a rail shape by arranging a plurality of rail plates in parallel in the width direction so that the game balls do not fall, and each rail There has been proposed one that allows only foreign matters to be dropped and removed from a gap formed between the plates (for example, see Patent Document 1).

Among these, the supply rod 4, the branch rod 5, the overflow rod 12, the recovery rods 17, 17, the guide rod 19, The flow-down grooves 9L and 9R and the connecting rods 10 and 10 constitute a game ball flow path through which the pachinko balls move (natural flow in this embodiment).

  As shown in FIGS. 2 and 3, the flow path protection member 50 is provided with a pair of side plates arranged at the side end portions in the front-rear width direction of the bottom plate 9 e, that is, at the left and right end portions in the flow-down direction of the pachinko balls. It consists of side ridges 51 and 52. The width direction of the bottom plate 9e and the side flanges 51 and 52 is a direction orthogonal to the front-rear width direction in FIG. 1, that is, the flow direction of the pachinko balls (longitudinal direction of each member).

  The pair of side flanges 51 and 52 are separately formed in a plate shape continuous in the longitudinal direction of the bottom plate 9e of the flow-down groove 9L by extruding a vinyl chloride resin material. In particular, in the side flanges 51 and 52, a so-called two-color / different material molding is used to integrally form a ball receiving portion 56 described later with a soft material, and the plate-like portion 54 and the side wall portion 55 with a hard material. The ball receiving portion 56 can absorb the impact and impact sound of the pachinko ball discharged from the out tank 8 through the discharge nozzle 8a. The material of the flow path protection member 50 is not limited to the vinyl chloride resin material, but a pachinko ball (for example, the ball tank 6 or the supply basket 4 of the pachinko game machine 2) dropped on the flow path protection member 50. Any other synthetic resin material or metal material can be used as long as it has a property capable of absorbing impact and impact sound without being damaged by an impact caused by an impact caused by an overflow ball 12 or the like. May be. Moreover, such a flow path protection member 50 is not necessarily provided.

  The side ridges 51 and 52 are provided with a plate-like portion 54 having a predetermined width dimension, a side wall portion 55 provided continuously from the outer end portion of the plate-like portion 54, and an inner portion of the side wall portion 55. And a ball receiving portion 56 projecting in the direction, and each of the ball receiving portions 56 is formed symmetrically in the flow direction of the sphere. In other words, the pair of side flanges 51 and 52 can effectively reduce the manufacturing cost because two members formed to have a predetermined length by extrusion molding may be disposed opposite to each other on the upper surface of the bottom plate 9e. Note that the upper surface of the plate-like portion 54 constituting the flow path bottom surface 54a through which the pachinko sphere flows down is formed so as to be inclined slightly downward toward the center in the width direction, and the pachinko sphere stays at the outer end. It is prevented.

  Next, a foreign matter removing structure for removing foreign matters such as nails and screws mixed in the downflow grooves 9L and 9R will be described with reference to FIGS. In addition, since the foreign substance removal structure in the downflow grooves 9L and 9R is configured similarly, only the foreign substance removal structure of the downflow grooves 9L and 9R will be described below, and the description of the foreign substance removal structure of the downflow grooves 9L and 9R will be omitted. .

  As shown in FIG. 5, in the downstream region (region on the side plate 9c side) of the downflow grooves 9L and 9R, foreign substances such as nails and screws mixed in the pachinko ball group flowing on the channel bottom surface 54a are removed. The foreign matter removing devices 100, 110, and 120 are disposed at a plurality of locations (three locations in this example). The foreign matter removing device 100 is disposed at a substantially central position in the width direction of the flow-down grooves 9L and 9R on the upstream side of the foreign matter removing devices 110 and 120, and the foreign matter removing devices 110 and 120 are located downstream of the foreign matter removing device 100 ( The downstream grooves 9L and 9R are disposed at both ends in the width direction of the downstream grooves 9L and 9R.

The foreign matter removing devices 100, 110, 120 are direction change plates 101, 111, 121 formed in a plate shape having a predetermined thickness (about 5 mm in this example) with a urethane rubber resin material having translucency, a wall member 102,112,12 2 arranged in plan view U-shaped so as to surround the region downstream of the direction changing plate 101, 111 and 121 in the channel bottom surface 54a, by a urethane rubber resin material having translucency is formed, the shutter plate 103,113,123 that can be opened and closed above the area enclosed by the wall member 102,112,12 2, is mainly composed.

  First, the foreign matter removing apparatus 100 will be described. The direction changing plate 101 is attached to a stay 150 formed in a band shape with a metallic structural material. The stay 150 has both ends in the longitudinal direction fixed to the side plates 9a and 9b of the flow-down grooves 9L and 9R, and is in a posture perpendicular to the flow path bottom surface 54a and between the flow path bottom surface 54a and the lower end edge. Are arranged in a direction perpendicular to the longitudinal direction of the flow-down grooves 9L and 9R so that a gap longer than the diameter of the pachinko sphere is formed.

  An attachment piece 151 having an L-shaped longitudinal section is connected to the lower end edge of the stay 150 from a substantially central portion in the longitudinal direction, and the direction change plate 101 is attached to the lower surface of the attachment piece 151 with screws 152a to 152c. It has been. A screw 152a disposed at the center in the longitudinal direction is a long screw, and is inserted from a top surface of the direction changing plate 101 into a cylindrical spacer member 153 disposed between the flow path bottom surface 54a and the direction changing plate 101. The plate-like portion 54 is screwed into the bottom plate 9e. Thus, by providing the spacer member 153, the width dimension between the flow path bottom face 54a and the direction change board 101 is maintained.

Since the downstream end portion of the direction change plate 101 is fixed to the upstream end portion of the wall member 102 standing on the flow path bottom surface 54a with a screw, the direction change plate 101 is a spacer. The member 153 and the wall member 102 are disposed horizontally at a predetermined height above the channel bottom surface 54a with respect to the channel bottom surface 54a.

  Further, the upstream end surface 105 facing the upstream side of the direction change plate 101 is directed toward the upstream side by the guide inclined surfaces 105a and 105b that are inclined toward the both ends from the substantially central position in the width direction. It is formed in a tapered shape. As shown in FIG. 7, the direction changing plate 101 is disposed with a gap L2 shorter than the diameter L1 of the pachinko sphere between the lower surface and the flow path bottom surface 54a (L1> L2).

  Specifically, as shown in the enlarged view in FIG. 7, the direction changing plate 101 is arranged in parallel with the flow path bottom surface 54a at an upper position spaced by a predetermined width (about 9 mm) from the flow path bottom surface 54a. Has been. On the other hand, since the diameter L1 of the pachinko sphere is about 11 mm, the upstream end face 105 is disposed at a predetermined height above the flow path bottom surface 54a so as to be able to contact the pachinko sphere. Therefore, the lower end edge part of the induction | guidance | derivation inclined surfaces 105a and 105b which comprise the upstream end surface 105 comprises the direction change part which contact | abuts the pachinko ball which flows down and changes the flow direction of this pachinko ball to the width direction.

  The opening / closing plate 103 has a rectangular shape in plan view and is formed in a size that can be placed on the upper end of the wall member 102. Further, one side on the upstream side is connected to the direction change plate 101 via a hinge 104, and is provided so as to be openable upward about the one side on the upstream side. Therefore, by opening the opening / closing plate 103, the foreign matter accommodated in the wall member 102 can be taken out from above as will be described later.

  The wall member 102 is installed between side walls 102a, 102a having a U-shaped longitudinal section extending from both ends in the width direction of the direction change plate 101 to the downstream side, and downstream ends of the side walls 102a, 102a. The downstream side wall 102b is formed in a U-shape in plan view, and is erected on the flow path bottom surface 54a so that the upstream side is open, and the outflow of foreign matters staying in the region surrounded by the side wall 102a and the downstream side wall 102b The outflow prevention part which blocks | prevents and the entrance prevention part which blocks | prevents the entrance of the pachinko ball to this area | region are comprised.

As described above, the foreign substance removing device 100 is erected so as to cover the direction change plate 101 and the opening / closing plate 103 disposed above the flow path bottom surface 54 a and the downstream side of the region formed below the opening / closing plate 103. that the wall member 102, the upstream side is formed in a pocket shape opening, with constitutes the yield capacity unit Z for accommodating foreign substances having passed through the direction changing unit, opening and closing plate 103, the upper side of the housing portion Z A covering portion to be covered is formed.

  Next, the foreign matter removing devices 110 and 120 will be described. The direction changing plates 111 and 121 of the foreign matter removing devices 110 and 120 are attached to a stay 160 formed in a band shape with a metallic structural material. The stay 160 has both ends in the longitudinal direction fixed to the side plates 9a and 9b of the flow-down grooves 9L and 9R, and is in a posture perpendicular to the flow path bottom surface 54a and between the flow path bottom surface 54a and the lower edge. Are arranged in a direction perpendicular to the longitudinal direction of the flow-down grooves 9L and 9R so that a gap longer than the diameter of the pachinko sphere is formed.

From the left and right sides in the longitudinal direction of the lower end edge of the stay 160, attachment pieces 161a and 161b having an L shape in a side view are connected to each other, and a direction changing plate 111 is attached to the lower surface of the attachment piece 161a by screws 162a and 162b. The direction change plate 121 is attached to the lower surface of the attachment piece 161b with screws 162c and 162d. Screws 162a and 162c arranged on the end side in the longitudinal direction are long screws, and cylinders arranged between the upper surface of the direction change plates 111 and 121 and the flow path bottom surface 54a and the direction change plates 101 and 102. Are inserted into the spacer members 163a and 163b and penetrated through the plate-like portion 54 and screwed into the bottom plate 9e. By providing the spacer members 163a and 163b in this way, the width dimension between the flow path bottom surface 54a and the direction change plates 1 1 1 and 1 1 2 is maintained.

  In the foreign matter removing apparatuses 110 and 120, only the shapes of the direction changing plates 111 and 121 are different, and the basic structure is almost the same as that of the foreign matter removing apparatus 100. Therefore, in the following description, only components having a configuration different from that of the foreign matter removing apparatus 100 will be described. Further, in the foreign matter removing apparatus 120, the same components as those of the foreign matter removing apparatus 100 are denoted by reference numerals obtained by adding 20 to the reference numerals of the foreign matter removing apparatus 100, and detailed description thereof will be omitted.

  The foreign matter removing devices 110 and 120 are different from the foreign matter removing device 100 in the upstream end face 115 of the direction changing plate 111 and the upstream end face 125 of the direction changing plate 121. The upstream end faces 115 and 125 are respectively provided in the downflow groove 9L. , 9R is composed of a straight guide inclined surface that flows down from the end in the width direction toward the center toward the downstream.

  As described above, the foreign matter removing devices 100, 110, and 120 arranged on the flow path bottom surface 54a constitute a foreign matter removing structure for removing foreign matters flowing through the downflow grooves 9L and 9R that are the game ball flow passages in the present invention. doing.

  Next, the flow situation when the pachinko sphere and foreign matter that flow down on the channel bottom surface 54a reach the foreign matter removing devices 100, 110, 120 will be described with reference to FIGS. In addition, since the flow-down situation when the pachinko ball and the foreign matter reach the foreign matter removal apparatuses 100, 110, and 120 is substantially the same, only the flow-down situation when the foreign matter removal apparatus 100 is reached will be described as an example here. In FIGS. 5 and 8, illustration of pachinko spheres and foreign objects unnecessary for explanation is omitted for the convenience of explaining the flow of pachinko spheres and foreign substances, but in reality, a large number of pachinko spheres flow down. , Foreign matter other than nails and screws may be mixed.

  As shown in FIG. 5, the pachinko balls in the flow-down grooves 9L and 9R roll from the inclined upstream side toward the downstream side (in the direction of the white arrow in the figure), that is, toward the inclined lower side on the flow path bottom surface 54a. While flowing down naturally. Further, the foreign matters mixed in the flow-down grooves 9L and 9R are gradually flowed down together with the pachinko balls while being pushed downstream by the pachinko balls flowing down one after another (see FIG. 8).

  As shown in FIG. 8, for example, when the nail Y which is an example of a foreign object flows down while being pushed by the pachinko ball P flowing down and reaches the foreign material removing apparatus 100, the pachinko ball P is guided by the inclined inclined surfaces 105 a and 105 b. However, the flow continues while being guided toward the width direction of the flow-down grooves 9L and 9R by the guide inclined surfaces 105a and 105b. That is, the flow direction of the pachinko ball P is changed to the width direction of the flow path bottom surface 54a by the contact with the guide inclined surfaces 105a and 105b. In addition, the guide inclined surfaces 105a and 105b are extended in a direction crossing the downflow grooves 9L and 9R in the width direction, but are arranged in an inclined shape with respect to the longitudinal direction of the downflow grooves 9L and 9R. The flow-down direction of the pachinko sphere P is only changed in the width direction (left-right direction) of the flow path bottom surface 54a, and the flow-down is not hindered by the guide inclined surfaces 105a and 105b and does not stay.

  On the other hand, in the nail Y that flows down while being pushed by the pachinko ball P, the nail Y whose head diameter is smaller than the width dimension of the gap L2 formed between the flow path bottom surface 54a and the lower surface of the direction change plate 101 is: Since it does not come into contact with the guide inclined surfaces 105a and 105b, it passes through the guide inclined surfaces 105a and 105b and enters below the direction changing plate 101 with the momentum pushed by the pachinko balls.

  As described above, the pachinko ball P is changed in the width direction by the contact with the guide inclined surfaces 105a and 105b, whereas the nail Y passes through the guide inclined surfaces 105a and 105b and the direction change plate 101 By entering the lower part, the pachinko ball is forcibly separated from the nail Y. Therefore, the nail Y does not stop being pushed by at least the pressed pachinko ball P by passing through the guide inclined surfaces 105a and 105b and entering the receiving portion Z on the downstream side thereof, but also another succeeding ball. It is pushed again by and does not continue to flow down endlessly.

  Further, the nail Y that has passed through the guiding inclined surfaces 105a and 105b and entered the housing portion Z flows out of the housing portion Z because the peripheral downstream side of the housing portion Z is surrounded by the wall member 102. Since the wall member 102 is erected to prevent the pachinko ball from entering the housing portion Z, the direction change plate 101 side When the pachinko ball flowing down the direction enters the inside of the housing portion Z, the nail Y is pushed out of the housing portion Z to flow out, thereby preventing the nail Y from flowing down again.

  Further, the direction changing plate 101 forming the guide inclined surfaces 105a and 105b is suspended below the stay 150 that is installed in the width direction above the flow path bottom surface 54a, so that the direction changing plate 101 flows. By disposing a member (for example, a support column) spaced apart above the road bottom surface 54a on the flow path bottom surface 54a, the flow of pachinko balls is inhibited, or nails or the like are placed on the flow path bottom surface 54a. The direction changing plate 101 can be disposed without damaging or distorting the flow path bottom surface 54a by the driving and hindering the flow of the pachinko balls.

  Further, by providing the spacer member 153 in the vicinity of the guide inclined surfaces 105a and 105b in the direction change plate 101, the direction change can be achieved even if the direction change plate 101 is bent or the stay 150 is loosely attached to the attachment piece 151. It can be maintained over a long period of time so that the width dimension of the gap formed between the plate 101 and the flow path bottom surface 54a does not change greatly.

  Further, since the spacer member 153 is erected on the flow path bottom surface 54a, the nail Y comes into contact therewith. However, since the spacer member 153 is cylindrical, the nail Y that comes in contact with the upstream side stays in place. Without being stuck to the nail Y along the peripheral surface of the spacer member 153, and is disposed at a substantially central position in the longitudinal direction of the upstream end surface 105. It is possible to reliably enter the accommodating portion Z from the gap formed on the side of the spacer member 153. Further, the spacer member 153 is disposed on the upstream side of the circumferential surface slightly downstream from the upstream end surface 105, thereby making contact between the nail Y staying upstream of the spacer member 153 and the pachinko ball P. It can be avoided as much as possible.

  In addition, the upper part of the accommodating portion Z formed on the downstream side of the guide inclined surfaces 105a and 105b is covered with the direction changing plate 101 and the opening / closing plate 103, so that, for example, the discharged balls discharged from the out tank 8 are accommodated. It is prevented that the nail Y falls off and stays in the portion Z, or the nail Y is ejected to the outside by the discharge ball that has dropped in the housing portion Z. Further, not only the discharge ball discharged from the out tank 8, but also a pachinko ball flowing down on the flow path bottom surface 54a jumps up for some reason, such as colliding with the upstream end surface 105, and enters the storage portion Z as it is and stays there. Is prevented.

  In addition, since the direction change plate 101 and the opening / closing plate 103 are translucent, it is possible not only to check the staying state of foreign matter in the accommodating portion Z from above without opening the opening / closing plate 103, but also to open / close the opening / closing plate 103. By opening the plate 103, foreign matters can be easily removed from above, so that maintainability is improved.

  By disposing the foreign matter removing device 100 on the flow path bottom surface 54a in this way, the flow direction of the pachinko sphere that has flowed down contacts the upstream end surface 105, and the flow direction is changed. Since the pachinko spheres P are separated, it is possible to prevent at least the foreign matter from being pushed down by the flowing down pachinko spheres and to prevent the flow of the pachinko spheres from being inhibited by the foreign matter.

  Further, on the downstream side of the upstream end surface 105, an accommodating portion Z that accommodates the foreign matter separated from the pachinko sphere is provided in the vicinity (in this case, continuous from the upstream end surface 105 toward the downstream side), and Since the entrance of the pachinko sphere into the storage portion Z and the outflow of foreign matter from the storage portion Z are prevented, only the staying foreign matter can be taken out and removed from the flow-down grooves 9L and 9R. In the present embodiment, the accommodating portion Z is continuously provided from the upstream end surface 105 toward the downstream side. However, if the accommodating portion Z is provided in the vicinity of the upstream end surface 105, the upstream end surface is not necessarily provided. Even if it is not provided continuously from 105, for example, the accommodating portion Z may be provided with a predetermined width away from the upstream end surface 105. In this case, the predetermined width dimension is preferably within the range of the diameter L1 of the pachinko sphere.

  In particular, the upstream end surface 105 extends in a direction crossing the flow path bottom surface 54a, that is, has a predetermined length in the width direction so as to change the direction so as not to completely inhibit the flow of the pachinko sphere. By being extended, even when a long foreign object such as a nail or a screw flows down in the horizontal direction, only the foreign object can be reliably retained in the housing portion Z and removed.

  Further, the direction changing portion for changing the flow direction of the pachinko sphere is formed in a rectangular shape in plan view, and is disposed with a gap L2 shorter than the diameter L1 of the pachinko sphere between the lower surface and the flow path bottom surface 54a. Since the direction change plates 101, 111, 121 are formed on the upstream end surfaces 105, 115, 125, which are the side end surfaces facing the upstream side, the direction change portion can be easily formed with a plate-like member. In addition, the upper part of the downstream area of the direction changing portion is covered with the direction changing plates 101, 111, 121, so that the pachinko to the downstream region is formed by the side end surfaces of the direction changing plates 101, 111, 121 other than the direction changing portion. Since the entry of the sphere is blocked, the foreign matter that has passed under the direction changing portion and has flowed down to the downstream region is prevented from being pushed out by the pachinko ball and flowing down again.

  Although a detailed description of the foreign matter removing devices 110 and 120 is omitted, since the configuration is basically the same, the same operations and effects as the foreign matter removing device 100 are achieved.

  Further, as shown in FIG. 5, the plurality of foreign matter removing devices 100, 110, and 120 are located at different positions in the downstream direction (longitudinal direction) and the width direction in the region near the downstream side of the downstream grooves 9L and 9R. At least one direction changing portion is arranged at all positions in the width direction. Specifically, the foreign matter removing device 100 is disposed at a substantially central position in the width direction in the vicinity of the downstream ends of the downflow grooves 9L and 9R, and the foreign matter removing devices 110 and 120 are downstream ends of the downflow grooves 9L and 9R, that is, Downstream from the foreign material removing apparatus 100, they are arranged in parallel and spaced apart at both ends in the width direction.

  More specifically, the foreign matter removing devices 100, 110, and 120 have a flow down region E1 where the upstream end surface 105 of the foreign matter removing device 100 crosses a predetermined flow down region in the flow path bottom surface 54a, and an upstream end surface 115 of the foreign matter removing device 110. Is divided in the width direction into a flowing area E2 crossed by the upstream end surface 125 of the foreign substance removing device 120, and a gap larger than the diameter of the game ball is at least between the flowing areas E1 to E3. It arrange | positions so that it may not be formed. In addition, each flow-down area | region E1-3 is an area | region divided by the left-right paired virtual straight line extended in a longitudinal direction so that it may each pass the both ends of the width direction of each upstream side end surface (direction change part).

  That is, the plurality of upstream side end surfaces 105, 115, and 125 as the direction changing portions are arranged in the width direction so that the pachinko sphere abuts at least one of the plurality of upstream side end surfaces when passing through the predetermined flow-down region. The pachinko ball is surely brought into contact with any one of the upstream end surfaces 105, 115, and 125 while passing through a predetermined flow-down region, so that the pachinko ball and the foreign object Therefore, it is possible to prevent foreign matter from flowing out of the communication port 10a and entering the lift polishing apparatus 25.

  In addition, the guide inclined surface 105a as the first direction changing portion has an end portion on the upstream end surface 115 side as the second direction changing portion disposed on the downstream side thereof on the downstream side toward the upstream end surface 115. The guide inclined surface 105b as the first direction changing portion is inclined and the end portion on the upstream end surface 115 side as the second direction changing portion disposed on the downstream side thereof is directed toward the upstream end surface 115. And tilted downstream. By doing in this way, the flow direction of the pachinko sphere which reached | attained the induction | guidance | derivation inclined surfaces 105a and 105b is changed toward the upstream end surfaces 115 and 125 of the downstream, so that the pachinko sphere becomes the upstream end surface 115, Since the chance of abutting 125 can be increased with certainty, pachinko balls and foreign substances can be reliably separated. The pachinko balls that have reached the upstream end faces 115 and 125 are each guided to the center in the width direction and flow down to the communication port 10a disposed on the downstream side.

  As described above, the pachinko sphere is changed in direction by coming into contact with at least one of the upstream side end surfaces 105, 115, and 125 when flowing down a predetermined flow-down region, so that it can be reliably separated from foreign substances.

  Further, in this embodiment, although the inclination directions of the upstream end faces 105, 115, 125 with respect to the flow direction (longitudinal direction) of the flow grooves 9L, 9R are different, the inclination angles are the same. By making the inclination angle of the upstream side end surfaces 115 and 125 disposed at the upstream side larger than the inclination angle of the upstream side end surface 105 disposed on the upstream side, the width dimension of the communication port 10a can be reduced to the flow-down grooves 9L and 9R. Even if it is smaller than the width dimension, the pachinko sphere can flow smoothly without being retained.

  Further, in this embodiment, the arrangement positional relationship between the out tank 8 that receives and discharges the pachinko balls discharged from the pachinko gaming machine 2 and the foreign matter removing devices 100, 110, and 120 is not described in detail. Each foreign matter removing device 100, 110, 120 is preferably arranged so as to avoid the pachinko ball discharge position in each out tank 8, and in this way, the pachinko ball discharged from the out tank 8 is removed by the foreign matter removing device. It is prevented that it falls to 100,110,120 and is damaged.

  In addition, each pachinko gaming machine 2 is preferably arranged on the upstream side of the foreign matter removing devices 110 and 120 arranged on the most downstream side closest to the communication port 10a. Even when a component provided in the pachinko gaming machine 2 falls into the flow-down grooves 9L and 9R, the component (foreign matter) can be removed.

  FIGS. 9A and 9B show another example of the arrangement of the foreign matter removing device. In the above embodiment, the foreign matter removing devices 110 and 120 are arranged on the end side in the width direction of the flow-down grooves 9L and 9R, on the downstream side of the foreign matter removal device 100 disposed in the center portion in the width direction of the flow-down grooves 9L and 9R. Although arranged in parallel, for example, as shown in FIG. 9A, on the downstream side of the foreign matter removing devices 110a, 110b, 120a, 120b disposed on the end side in the width direction of the flow-down grooves 9L, 9R, The foreign matter removing apparatus 100 may be disposed at the center in the width direction.

  Further, the foreign-matter removing devices 110a and 110b and the foreign-matter removing devices 120a and 120a are disposed apart from each other in the widthwise ends of the flow-down grooves 9L and 9R, and the upstream end surfaces 115 and 125 have different inclination directions (opposite directions). 120b is not limited to being arranged in parallel in the width direction, and as shown in FIG. 9A, a plurality of staggered arrangements are arranged at different positions in the longitudinal direction (downflow direction) of the downflow grooves 9L and 9R. In this way, the pachinko balls flow down while repeating meandering, and can flow down evenly while repeating the direction change.

  In such a case, the plurality of foreign matter removing devices 100, 110a, 110b, 120a, and 120b are arranged so that a gap of at least the diameter L1 of the pachinko sphere is not formed between the corresponding flow-down areas E1 to E3. Therefore, the pachinko ball can be brought into contact with any one of the upstream end faces 105, 115, and 125 while passing through the predetermined flow-down areas E1 to E3.

  Further, the upstream end surface of the foreign matter removing device (for example, the foreign matter removing device 110a, 110b) on the upstream side of one of the plurality of foreign matter removing devices (for example, the foreign matter removing devices 120a, 120b) is the upstream side of the one foreign matter removing device. By being formed to be inclined toward the downstream side toward the end surface 115, the chance that the pachinko sphere is guided to the upstream end surface 125 of the one foreign material removing device and separated from the foreign material is increased.

  Further, as shown in FIG. 9B, the foreign matter removing devices 110a and 110b arranged at one end portion in the width direction, the foreign matter removing devices 130a to 130c arranged at the center portion in the width direction, and the other in the width direction. You may arrange | position the foreign material removal apparatus 120 arrange | positioned at an edge part toward a downstream side in order.

  Further, in such a case, the plurality of foreign matter removing devices 110a, 110b, 130a to 130c, 120 are arranged so that a gap of at least the diameter L1 of the pachinko sphere is not formed between the corresponding flowing areas E1 to E3. Therefore, the pachinko sphere can be reliably brought into contact with any one of the upstream end faces 115, 125, 135 while passing through a predetermined flow-down region.

Further, in FIG. 9 (a), but upstream end surface 115, 125 tilt directions are different have been arranged alternately toward the flow-down direction, as shown in FIG. 9 (b), the inclination direction the same upstream The end surfaces 115 and 135 may be continuously arranged in the flow direction.

  In the present embodiment, the direction change plates 101, 111, 121 are arranged in parallel to the flow path bottom surface 54a at an upper position separated by a predetermined width (about 9 mm) from the flow path bottom surface 54a. If the gap L2 shorter than the diameter L1 of the pachinko sphere is provided between at least the lower edge of the upstream end surfaces 105, 115, and 125 and the flow path bottom surface 54a, the direction changing plates 101, 111, 121 may not necessarily be arranged parallel to the flow path bottom surface 54a. For example, 121 may be disposed so as to be inclined toward the flow path bottom surface 54a toward the downstream side. The ball discharged from the pachinko gaming machine 2 is prevented from dropping and staying on the upper surface of the direction changing plate.

  Furthermore, the separation width between the lower end edge of the upstream side end surfaces 105, 115, and 125 and the flow path bottom surface 54a, that is, the width dimension of the gap L2, does not have to be about 9 mm as described above. If it is shorter than L1, it may be, for example, about 10 mm or less than 9 mm, but there is no hindrance to the flow (direction change) of the pachinko sphere, and a width that allows the passage of as much foreign matter as possible. The dimensions are preferred.

  Further, in the present embodiment, the foreign matter removing device disposed in the downflow grooves 9L and 9R has been described. However, as shown in FIGS. 1 and 4, the foreign matter disposed in the junction portion 22 in the downflow grooves 9L and 9R. Even if it exists in the removal apparatuses 210 and 220, there exists an effect | action and effect similar to the foreign material removal apparatuses 110 and 120. Further, although not particularly shown, a foreign substance removing device may be provided on the upstream side of the partition plate 21.

  Next, a foreign matter removing apparatus as a modification of the present invention will be described with reference to FIGS. FIG. 10 shows a foreign matter removing apparatus as a first modification of the present invention. FIG. 11 shows a foreign matter removing apparatus as a second modified example of the present invention. FIG. 12 shows a foreign matter removing apparatus as a third modified example of the present invention. FIG. 13 shows a foreign matter removing apparatus as a fourth modification of the present invention. FIG. 14 shows a foreign matter removing apparatus as a fifth modified example of the present invention.

(Modification 1)
As shown in FIG. 10, the foreign matter removing apparatus 200 according to the first modification includes an upper plate 201 a, a lower surface and a side wall 201 b and a downstream side wall 201 c that are suspended downward from edges other than the upstream side of the upper plate 201 a. It is comprised by the direction change member 201 opened to an upstream. Thus, the direction changing plate and the wall member may be provided integrally.

  Further, the direction changing portion is not limited to a linear shape as in the above-described embodiment, but is curved downstream from the longitudinal center toward both ends as in the upstream end face 205. You may form in planar view circular arc shape.

  Further, since the upper surface 201d of the upper plate 201a is formed as an inclined surface that is inclined downward toward the downstream end, pachinko balls can be prevented from staying on the upper surface 201d of the upper plate 201a.

  Note that the upper surface 201d of the upper plate 201a as the covering portion that covers the upper side of the housing portion Z is, for example, only a partial region of the upper surface 201d if at least a portion thereof is inclined downward toward the end portion side. May be an inclined surface. Further, the inclination direction can be variously changed, and may be an inclined surface inclined toward the end portion in the width direction, or an inclined surface inclined toward the entire edge portion from the center. May be. Furthermore, the upper surface 201d may be inclined by forming the upper plate 201a to be inclined without forming the upper surface 201d of the upper plate 201a in an inclined shape.

(Modification 2)
As shown in FIG. 11, the foreign matter removing apparatus 210 according to the second modified example has a longitudinal section downwardly opened to the lower surface and the upstream / downstream side by an upper plate 211a and a side wall 211b hanging downward from the upper plate 201a. It is comprised by the direction change member 211 which makes a U-shape.

  In addition, a through hole 212 having substantially the same shape as the upper plate 211a is formed in the channel bottom surface 54a below the upper plate 211a so as to penetrate the plate-like portion 54 and the bottom plate 9e in the vertical direction. The nail Y that has passed through the through hole 212 is discharged below the flow-down grooves 9L, 9R and falls onto the floor surface inside the gaming machine installation island 1.

By doing in this way, the nail Y that has passed through the upstream end face 215 does not stay on the flow path bottom face 54a and falls directly below the flow path bottom face 54a. As a result, it is not necessary to provide a blocking wall or the like for preventing the outflow of water, and maintenance is improved because it is not necessary to periodically remove the accumulated foreign matter. That is, the through-hole 212 constitutes an accommodating portion Z that accommodates foreign matter that has passed through the upstream end surface 215 serving as a direction changing portion, and an outflow prevention portion that prevents the foreign matter from flowing out from the accommodating portion Z. Also, volume unit yield Z is not limited to long-term residence in the flow path bottom 54a, if it is temporarily housed capable constructed near the downstream side position of the upstream end surface 215 as described above, after receiving Also included is a structure that discharges to a location other than the channel bottom surface 54a.

  Further, as shown in the enlarged view in FIG. 11B, the upstream side edge of the through-hole 212 is located on the upstream side of the upstream end surface 215 and the center of the pachinko sphere P in contact with the upstream end surface 215. By providing it at a position downstream of the position P1, the nail can be dropped without staying near the upstream end face 215 without dropping the pachinko ball.

  That is, as long as the accommodating portion Z is disposed in the vicinity of the upstream end surface 215 constituting the direction changing portion, the accommodating portion Z is not necessarily provided continuously only toward the downstream side of the direction changing portion. It may be provided continuously toward directly below and upstream.

(Modification 3)
As shown in FIG. 12, the foreign substance removing device 220 as the third modification is configured by only one direction changing plate 221 and is suspended above the flow path bottom surface 54a by the above-described stay 150 or the like. Has been.

  Further, in the accommodating portion Z formed below the direction changing plate 221 in the flow path bottom surface 54a, a plurality of convex ribs 222 extending in the width direction are provided protruding at predetermined intervals toward the downstream side. Since 54a is formed in the uneven | corrugated shape, resistance can be provided with respect to a foreign material by this. Therefore, the nail Y that has passed through the upstream end face 225 is likely to stay on the accommodation portion Z without providing a blocking wall or the like that prevents the foreign substance from flowing down on the downstream side or side of the direction changing member 211 as described above. Become. In other words, the plurality of ridges 222 constitute an outflow prevention unit that prevents the outflow of the foreign matter stored in the storage unit Z through the upstream end surface 225 as the direction changing unit. Further, the end face other than the upstream end face 225 in the direction changing plate 221 constitutes an entry preventing portion that inhibits the pachinko ball from entering the housing portion Z.

  In this example, the outflow prevention portion is configured by the plurality of ridges 222.
