  The upper passage cover 118, the linear passage cover 104, the rounded passage cover 105, and the ball introduction passage cover 106 that are arranged to face the outer surface of the conveyance belt 103 are circulated by the rotation of the upper roller 101 and the lower roller 102. A passage member for pressing and feeding the pachinko ball to the belt 103 is configured.

  The lower roller 102 is a drive roller driven by a lifting motor (not shown) provided at the lower part of the main body, and the upper roller 101 is a driven roller so as to rotate in the arrow direction (clockwise) in FIG. It has become. Further, as shown in FIG. 5, a plurality of driven rollers 107 to 109 are disposed above the lower roller 102, and the conveyor belt 103 is also stretched around these driven rollers 107 to 109. At the same time, any one of these is a tension roller capable of adjusting the tension of the conveyor belt 103.

  As shown in FIG. 4, the linear passage cover 104 is provided on the rear surface side of the main body 100, that is, the outer surface on the ascending side of the conveyor belt 103 so as to be openable and closable. The upper, middle and lower locking members 111a to 111c pivotally attached to the main body 100 are locked to the locking pins 112a to 112c so that they can be locked at the closed position.

  As shown in FIG. 6 in particular, the inner surface of the linear passage cover 104 has a plurality of rows of substantially hemispherical concave grooves 113 for forming a linear passage 115 extending in the vertical direction (in this embodiment, 7) A vertically long passage plate 114 formed side by side is arranged, and when the linear passage cover 104 is located at the closed position, it is arranged to face the outer surface of the conveyor belt 103, and the plurality of concave grooves 113 forms a plurality of rows of linear passages 115 extending in the vertical direction.

  The pachinko spheres P in the linear passages 115 guided by the concave grooves 113 are pressed against the conveying belt 103 by the passage plate 114, and the inside of the passage is directed upward by the movement of the conveying belt 103. It is moved and lifted.

  In addition, a cleaning cloth 116 for cleaning pachinko balls transferred in each passage is laid on the inner surface side of the passage plate 114, so that the pachinko balls P are conveyed by the passage plate 114 via the cleaning cloth 116. By being pressed toward the belt 103, the pachinko ball P is transferred while being slidably contacted with the cleaning cloth 116 by the movement of the conveying belt 103, so that the pachinko ball is cleaned together with the lifting. That is, the lifting device 25 in the present embodiment is a lifting and cleaning device that lifts the pachinko ball P while cleaning it.

  The cleaning cloth 116 has a belt shape and is laid in the vertical direction along the inner surface of the passage plate 114 of the linear passage cover 104. The upper and lower ends of the cleaning cloth 116 are applied to the linear passage cover 104 with a predetermined tension. Folded outward at the upper and lower ends, respectively, and can be stopped by a cloth band 117 (see FIG. 5) provided at the lower part of the outer surface of the linear passage cover 104. The cleaning cloth 116 laid in this way can be replaced with a new cleaning cloth 116 by releasing the stopper by the cloth band 117 when the sliding contact surface with the pachinko ball becomes dirty. Yes.

  As shown in FIG. 5, the linear passage 115 formed by the linear passage cover 104 is formed on the front side of the main body 100 from the upper shaft 101 a to the lower shaft 102 a, that is, on the ascending side of the conveying belt 103. ing. Then, the pachinko ball P transferred upward in the linear passage 115 is folded back to the front side (right side in FIG. 5) by an arc-shaped upper passage 119 formed by an upper passage cover 118 provided at the upper portion of the main body 100. After that, it flows down the discharge cover 120 connected to the upper passage cover 118, is discharged from the discharge port 38 formed in the discharge cover 120, and is stored in the upper tank 3. .

  Below the straight passage 115, that is, on the upstream side, a round-shaped passage 121 formed by the round-shaped passage cover 105 described above is formed, and flows from a spherical inlet 122 provided at the lower front side of the main body 100. The pachinko balls to be guided are guided toward the upper linear passage 115.

  A pachinko sphere P flowing down the sphere introduction passage 123 formed by the sphere introduction passage cover 106 provided at the sphere inlet 122 on the upstream side of the round passage cover 105 is introduced into the round passage 121. It has become.

  At the upstream end of the ball introduction passage cover 106, as shown in FIG. 7, there is provided a junction 124 where the pachinko balls that have flowed down the relay rods 24L and 24R described above merge. The junction portion 124 includes a junction plate 125 disposed at a lower position between the end portions of the left and right relay rods 24L and 24R, and a snorkel rail 126 disposed below the junction plate 125. In addition, the code | symbol 127 in FIG. 7 is a partition plate arrange | positioned between the edge parts of right and left relay rod 24L, 24R, and it is prevented that a flow-down is restrict | limited by the pachinko ball which flows out from the opposite cage | basket. It has become so.

  The junction plate 125 is formed with a plurality of large-diameter holes 125a having a diameter of about 20 mm for dropping pachinko balls flowing out from the ends of the relay rods 24L and 24R. The fallen pachinko ball is dropped from the large-diameter hole 125a, so that, for example, a large foreign object such as a prepaid card used for lending the pachinko ball is captured, and entry into the lifting device 25 is prevented. ing.

  The pachinko balls that have fallen from the large-diameter hole 125a flow down the snocorail 126 (see FIG. 8) disposed so as to be inclined downward toward the ball introduction passage 123, and flow into the ball introduction passage 123. It has become. Then, when falling on the snorkel rail 126 and flowing down, the foreign matter that has fallen through the large-diameter hole 125a falls into the space 128 provided below from the gap of the snorkel rail 126 and is removed. It has become.

  Note that the diameter of the large-diameter hole 125a is set to a size that allows an appropriate amount of pachinko balls flowing into the merge portion 124 to be dropped on the snorkel rail 126 below the large amount without falling. In this way, by suppressing the outflow amount of the pachinko sphere onto the snorkel rail 126, a large amount of the pachinko sphere flows into and fills the snocorail 126 and the sphere introduction passage 123 on the downstream side thereof, thereby the inflow port 112. A high ball pressure is applied to the lower roller 102 and the conveyor belt 103 in the vicinity, and an excessive load is prevented from being applied to a feed motor (not shown) that drives the lower roller 102 to rotate.

  The lifting device 25 configured as described above flows down the relay rods 24L and 24R, is discharged to the joining portion 124, joins, and is guided by the snorkel rail 126 and the ball introduction passage 123 and passes through the ball inlet 122. The pachinko balls that have flowed into the interior are moved through the rounded passage 121, the straight passage 115, and the upper passage 119 by the movement of the conveyor belt 103, and are lifted upward while being cleaned by the cleaning cloth 116, and It can discharge | emit from the discharge port 38 provided in this.

  Next, detailed structures of the rounded passage cover 105, the ball introduction passage cover 106, and the snocorail 126 will be described with reference to FIGS.

  First, as shown in FIG. 8 and FIG. 9, the snowboard rail 126 is disposed between the eight side wall rails 130 that form the side surface of the flow path of the pachinko sphere and the side wall rails 130. The seven bottom wall rails 131 constituting the bottom surface of the passage and the base body 132 that integrates the side wall rail 130 and the bottom wall rail 131 are formed, and seven rows of downflow passages 135 are formed. A plurality of openings 133 are formed on the side of each bottom wall rail 131, and foreign substances fall below the base body 132 through these openings 133.

  The ball introduction passage cover 106 is formed of a synthetic resin material such as polycarbonate, and is disposed between eight side plates 140 that form the side surfaces of the downflow passages of the pachinko spheres and the side plates 140. 7 side plates 141 constituting the bottom surface, and the side plates 140 standing on the floor surface are integrated with each other by the bottom plate 141, and seven rows of ball introduction passages 123 are formed between the side plates 140. Has been.

  The end face of each side plate 140 facing the lower roller 102 is cut out in an arc shape centering on the lower shaft 102a of the lower roller 102, and is close to the outer surface of the conveyor belt 103 as shown in FIG. It can be arranged. More specifically, the end surface of each side plate 140 facing the lower roller 102 is formed by a curved surface corresponding to about ¼ of the circumference of the lower roller 102. In this way, the sphere introduction passage cover 106 is erected on the floor surface, and has a plurality of side plates 140 arranged in parallel at equal intervals in the passage width direction, and a bottom plate 141 disposed between the side plates 140, 140. , And is formed in a cubic shape in which a portion facing the lower roller 102 is recessed in a curved shape.

  Each bottom plate 141 is composed of a strip-like plate material extending in the longitudinal direction of the sphere introduction passage 123, and is inclined downward from the end portion on the snoco rail 126 side toward the end portion on the round-shaped passage cover 105 side. The pachinko ball from the snowboard rail 126 is guided to the rounded passage 121 by flowing down.

  Further, from the lower ends of the side plates 140, 140 at both ends in the passage width direction, a fixing piece 142 for fixing the sphere introduction passage cover 106 to the base plate 110 is continuously provided outwardly and formed on the fixing piece 142. A fixing screw (not shown) is inserted into the mounting hole 143 and is screwed into the base plate 110 so that it can be fixed to the base plate 110.

  The sphere introduction passage cover 106 configured in this way is configured such that the lower ends of the left and right side plates 140 are installed on the base plate 110, and as shown in FIG. A downstream end (front end) is inserted into the space between the lower rear surface side of the lower roller 102 and the base plate 110, and the opposite end surface of each side plate 140 facing the lower roller 102 is disposed close to the conveying belt 103. Is done.

  The rounded passage cover 105 is spaced apart at intervals L2, L2 ′ wider than the diameter L1 of the pachinko ball P, forms the side surface of the rounded passage 121, and guides the game ball along the rotation direction of the lower roller 102 The guide plate 150 as a guide member to be moved and the guide plate 150 and 150 adjacent to each other are arranged with a gap (S1) narrower than the diameter (L1) of the pachinko sphere, and are conveyed over the lower roller 102 And a pressing plate 151 as a pressing member having a pressing surface 151 a as a pressing surface portion for pressing a pachinko ball against the belt 103. The guide plate 150 is made of a synthetic resin material such as polycarbonate (for example, Rockwell hardness M scale 65 to 78, R scale 121 to 127) having excellent heat resistance and wear resistance and higher hardness than the pressing plate 151. These guide plates 150 are integrated with each other by an upstream piece 152, a downstream piece 153, a downstream lower piece 154, and a part of the intermediate guide piece 155 to constitute a main body.

  Since parts other than the upstream piece 152, the downstream piece 153, the downstream lower piece 154, and the intermediate guide piece 155 are open, foreign matter is present in the gap S 1 between the guide plate 150 and the pressing plate 151. It is easier to be pushed into the back side than the pressing surface 151 a of the pressing plate 151.

  Further, in this embodiment, the guide plate 150 and the pressing plate 151 are configured by a plate material that has a flat plate portion extending in the vertical direction as a whole, but the present invention is not limited to this, for example, Only a part of the guide plate 150 in the vicinity of the end surface facing the lower roller 102, the vicinity of the pressing surface 151a of the pressing plate 151, or the like may be configured by a member configured by a flat plate portion.

  Each guide plate 150 is formed in a substantially triangular shape when viewed from the side, and is erected vertically on the base plate 110. The end surface facing the lower roller 102 is cut out in an arc shape centering on the lower shaft 102a of the lower roller 102 so that it can be disposed close to the outer surface of the conveyor belt 103 as shown in FIG. It has become. More specifically, the end face of each guide plate 150 facing the lower roller 102 is formed by a curved surface corresponding to about ¼ of the circumference of the lower roller 102. In this way, the rounded passage cover 105 is erected on the floor surface, and a plurality of guide plates 150 arranged in parallel in the passage width direction at equal intervals, and a pressure disposed between the guide plates 150 and 150. The plate 151 is formed in a cubic shape in which a portion facing the lower roller 102 is recessed in a curved shape.

  Further, from the lower ends of the guide plates 150 and 150 at both ends in the passage width direction, attachment pieces 156 for attaching the rounded passage cover 105 to the base plate 110 are continuously connected outwardly, and formed on the attachment pieces 156. The mounting screw 158 (see FIG. 13A) is inserted into the mounting hole 157 and screwed into the base plate 110, so that it can be detachably attached to the base plate 110.

  On the upstream side of the lower end surface 150 a of each guide plate 150 (the lower surface on the sphere introduction passage cover 106 side), an inclined surface 150 b that is inclined upward toward the upstream end, that is, the sphere introduction passage cover 106 is formed. As will be described later, when the rounded passage cover 105 is removed from the mounting position, the upstream end can be tilted downward.

  Further, as shown in FIG. 10A, the upstream side of each guide plate 150 is formed with a thin portion 159 having a smaller thickness than the downstream side, whereby the upstream side width of the rounded passage 121 is formed. The dimension L2 ′ is wider than the downstream width dimension L2. Specifically, the downstream width L2 and the upstream width L2 'of the rounded passage 121 are larger than the diameter L1 of the pachinko sphere P (L1 <L2 <L2'). As a result, the receiving port for the pachinko sphere that has flowed in from the ball introduction passage 123 is widened, so that it is difficult for a ball to be clogged or the like at the joint portion, and foreign matter is easily dropped from a deformation allowable space portion 164 described later.

  Between the opposing surfaces of the upstream piece 152 and the downstream piece 153 and between the guide plates 150 of the intermediate guide piece 155 to be described later, the pressing plates 151 are directed in the vertical direction for inserting and removing the vertical plates (see FIG. 8). Guide grooves 152a, 153a, and 155a are formed, and the pressing plates 151 are sandwiched. The pressing plate 151 guided by these guide grooves 152a, 153a, 155a is formed by the upper end of the downstream lower piece 154 and the lower end of the guide groove 155a formed in the intermediate guide piece 155, as shown in FIG. It is received from below and positioned.

  From both side surfaces of the downstream end (upper end) of each guide plate 150, a horizontal guide piece 160 extending in the horizontal direction continuously provided at the upper end of the downstream piece 153 is projected toward the passage, From the front ends of these horizontal guide pieces 160, arcuate guide pieces 161 along the arcuate end surface of the guide plate 150 are provided continuously toward the upstream side (downward). Further, on the upstream side of the arcuate guide piece 161, an arcuate guide piece 162 having the same curvature as that of the arcuate guide piece 161 is projected from the side surface of each guide plate 150 into the passage. From the lower surface of the upstream end of the piece 162, the above-described intermediate guide piece 155 is suspended downward. The opposing end surfaces of the horizontal guide piece 160, the arc-shaped guide pieces 161 and 162, and the intermediate guide piece 155 are separated from each other by the same size as the thickness of the pressing plate 151 so that the pressing plate 151 can be inserted between these opposing end surfaces. The inserted pressure plate 151 is sandwiched and guided from the left and right sides.

  As described above, the intermediate guide pieces 155 are separated from each other downward from the lower surfaces of the upstream end portions of the arcuate guide pieces 162 and 162 projecting from the opposing surfaces of the adjacent guide plates 150 and 150, respectively. The guide grooves 155a described above are formed as bottomed guide grooves extending in the vertical direction, and the guide plates 150 and 150 adjacent to each other in the lower portion. They are linked together.

  The upper surfaces of the arcuate guide pieces 161 and 162 are arranged at a position slightly lower than the end surface of the pressing plate 151, that is, the bottom surface of the rounded passage 121, and do not come into contact with the pachinko balls P passing therethrough. By sandwiching the side surface of the pressing plate 151 near the pressing surface 151a from the left and right sides in the width direction, elastic deformation in the width direction of the passage is prevented.

  The upstream end of the arcuate guide piece 161 and the downstream end of the arcuate guide piece 162 are spaced apart by a predetermined distance to form a deformation allowing space 163, and the arcuate guide piece 162 has The upstream end portion and the upstream piece 152 are spaced apart by a predetermined distance to form a deformation allowing space 164. That is, the pressing surface 151a of the pressing plate 151 to be described later can be easily elastically deformed at two locations of these deformation permissible space portions 163 and 164.

  Each guide plate 150 is formed with two through holes 166a and 166b through which two through pins 165a and 165b for holding a later-described pressing plate 151 are inserted, and the through pins 165a and 165b are respectively provided. The R-shaped passage 121 can be inserted from either side of the width direction.

  Thus, the guide plate 150 and the pressing plate 151 have flat plate portions extending in the vertical direction, and by inserting the insertion pins 165a and 165b through the through holes 166a and 166b formed in these flat plate portions, Since each pressing plate 151 can be fixed to a main body portion in which a plurality of guide plates 150 are integrated, the pressing plate 151 can be easily assembled to the guide plate 150.

  In addition, an insertion piece 167 that is inserted into the lower space of the sphere introduction passage cover 106 protrudes from the surface of the upstream piece 152 that faces the sphere introduction passage cover 106, so that the upstream end is introduced into the sphere. It is locked to the passage cover 106 to prevent the floating.

  As shown in FIG. 8, the pressing plate 151 is in contact (rolling or sliding) with the end surface facing the lower roller 102, that is, the bottom surface of the rounded passage 121, that is, the pachinko ball. A plate-like hard member having a pressing surface 151a that constitutes a pressing surface portion that presses toward the conveying belt 103 is formed in a substantially L shape in a side view formed by being cut out in an arc shape centering on the lower shaft 102a of the lower roller 102. It is composed of a urethane resin material. As this hard urethane resin material, one having a rubber hardness of 90 in JIS standard is used, but this rubber hardness can press the pachinko ball P against the conveyor belt 103, and a load due to foreign matter is added as will be described later. As long as the hardness can be elastically deformed, the numerical range may be, for example, HS 60-100.

  At the downstream end (upper end) of each pressing plate 151, a substantially U-shaped cutout groove 168 that opens upward is formed, whereby the downstream end of the pressing surface 151a is elastically deformed outward. Therefore, the pressure applied to the pachinko ball is relieved at the downstream end of the rounded passage 121, that is, in the vicinity of the junction with the linear passage 115.

  Each pressing plate 151 is aligned with the axial center of the through holes 166a and 166b formed in each guide plate 150 in a state where the pressing plate 151 is disposed at a fixed position between the respective guide plates 150. Two through-holes 169a and 169b through which 165a and 165b are inserted are formed, and the through-pins 165a and 165b are inserted so that a fixed position (see FIG. 9) provided between the guide plates 150 is provided. Deviations upward are regulated.

  The rounded path cover 105 configured in this way is configured such that the lower ends of the left and right guide plates 150 are installed on the base plate 110, and as shown in FIG. The upstream end portion (rear end portion) is inserted into the space between the lower front surface side of the lower roller 102 and the base plate 110, and the end surface of each guide plate 150 facing the lower roller 102 is brought close to the conveying belt 103. Arranged in a state.

  Next, the operation of the rounded passage cover 105 configured as described above will be described with reference to the drawings.

  First, as shown in FIG. 7, the rounded path cover 105 configured as described above is disposed so as to face the lower front side of the lower roller 102, so that the upstream end of the rounded path 121 A pachinko ball flowing down from the sphere introduction passage 123 is connected to the downstream end of the sphere introduction passage 123 arranged to face the lower rear surface side of the lower roller 102, and the outer surface of the conveyor belt 103 at the position of the lower roller 102 And the guide plates 150 and 150 and the pressing surface 151a of the pressing plate 151 enter the rounded path 121 surrounded by the pressing plate 151a. The pachinko ball P that has entered the rounded passage 121 is pressed toward the rotating conveyor belt 103 by the pressing surface 151a of the pressing plate 151, so that the movement of the conveyor belt 103 causes the arrow direction in FIG. From the position immediately below the lowermost end of the lower roller 102, the lower roller 102 is transferred upward along the outer periphery of the lower roller 102 toward the front side.

  At this time, since the pressing plate 151 is made of a hard urethane resin material, the pachinko ball P can be elastically biased toward the conveying belt 103 by the pressing surface 151a which is the end surface of the pressing plate 151. 151 is transported to the pachinko ball P without being provided so as to bias the guide plate 150 against the transport belt 103 or to bias the rounded path cover 105 itself toward the transport belt 103. Since an urging force in the direction of the belt 103 can be appropriately applied, the pachinko ball can be reliably pressed against the conveying belt 103 and transferred.

  Here, for example, as shown in FIG. 12, a description will be given of the case where the screw B, which is a foreign object, enters the rounded passage 121 together with the pachinko ball. The screw that is pushed by the pachinko ball and enters the rounded passage 121. Even if a part of B (for example, the head) is larger than the gap S1 formed between the opposing surfaces of the guide plate 150 and the pressing plate 151, the pressing force from the conveyor belt 103 always acts on the screw B. Therefore, when reaching the deformation allowable space 164, the screw B is forcibly pushed between the pressing plate 151 and one of the left and right guide plates 150 by the pressing force of the conveying belt 103, and the pressing is thereby performed. The pressing plate 151 and one guide plate 150 are elastically deformed in the width direction by the pressing surface 151a of the plate 151 and its vicinity, that is, at least a part of the pressing surface portion. Bis B writes fits between the gap S1 is pushed open pressing plate 151 and the guide plate 150.

Thus, the gaps S1 and S1 are formed between the left and right guide plates 150 and 150 adjacent to the pressing plate 151, and the pressing plate 151 is made of a hard urethane resin material that can be elastically deformed. Thus, the pressing surface 151a of the pressing plate 151 constituting the pressing surface portion of the rounded passage 121 and the vicinity thereof can be deformed in the width direction of the passage, that is, elastically deformable between the adjacent guide plates 150, 150. Therefore, when the screw B passes through the deformation permissible space 164 or the deformation permissible space 163 on the downstream side, the space between the pressing plate 151 and one guide plate 150 is expanded by the screw B. It is easy to fit between them. That is, since the gaps S1 and S1 are formed on both sides of the pressure plate 151 in the passage width direction, the pressure plate 151 is allowed to be spread toward one of the guide plates 150. Since the gap S1 on the side where the screw B is fitted with the boundary 151 is pushed wide in the passage width direction and the other gap S1 is narrowed in the passage width direction, the gap between the opposing surfaces of the guide plate 150 and the pressing plate 151 is reduced. Even when a foreign matter such as screw B having a portion larger than the gap S1 formed in the case enters, the foreign matter is effectively prevented from being transferred together with the pachinko sphere P.

  Note that the upstream deformation allowable space 164 is the first part that presses the pachinko ball that has flowed into the rounded passage 121 toward the conveyor belt 103, so that foreign matter is easily pushed into the gap S1, and the downstream side In the deformation allowable space 163, since the upward movement of the pachinko sphere is started in the rounded passage 121, the force that presses the pachinko sphere toward the transport belt 103 is high, so the foreign matter is in the gap S1. It is easy to be pushed into.

  Further, since the pressing plate 151 is constituted by an elastic deformation member, after the force B is forcibly deformed by the screw B, the elastic restoring force works, so that the screw B that has been fitted in the pressing plate 151 and the guide By being sandwiched between the plate 150 and being difficult to come off, even if it is pushed by a subsequent pachinko ball, it is difficult to be lifted together with the subsequent pachinko ball. Therefore, since foreign matter can be retained in the rounded passage 121, it is possible to prevent damage to the conveyor belt 103, supply of pachinko balls to the pachinko machine 2, and troubles in pachinko ball circulation in the game island platform. Is done.

  Further, as compared with the case where the pressing plate 151 is made of a polycarbonate resin material or the like like the guide plate 150, the friction coefficient of the pressing surface 151a of the pressing plate 151 and the side surface in the vicinity thereof is high, and toward the gap S1. The pushed-in foreign matter is more easily caught.

  Next, the state of removal of the rounded path cover 105 when a ball clogging occurs in the rounded path 121 as described above or when performing regular maintenance work will be described.

  First, as described above, when a ball clogging occurs in any of the rounded passages 121 in the plurality of rows, the linear passage cover 104 of the main body 100 is first opened, and the vertical direction attached to the inner surface of the cleaning cloth 116 Check for streak-like dirt (not shown). Since these streak stains are generated corresponding to the respective linear passages 115, when the cleaning is performed normally, seven rows of streak stains are generated corresponding to the seven passages. However, for example, as described above, when a foreign substance is fitted in the rounded passage 121 to cause clogging of a ball, only the streak-like dirt in that row becomes thinner than the others, and this causes clogging of the ball. I can recognize that.

  When the rounded path cover 105 is removed from the attachment position, the left and right attachment screws 158 are first removed as shown in FIG. Then, as shown in FIG. 13 (b), with the upstream side of the rounded passage cover 105 slightly tilted downward (in the direction of the white arrow in FIG. 13 (b)), the upper surface of the base plate 110 is on the front side ( In FIG. 13 (b), it may be pulled out by sliding in the direction of the two-dot chain line arrow, the direction of the axis of the lower roller 102 (the direction intersecting the longitudinal direction of the lower shaft 102a).

As described above, even if the lower roller 102 is disposed so as to face the lower side, the base plate 110 can be simply pulled out by sliding the upper surface of the base plate 110 toward the front side without removing the ball introduction passage cover 106. It can be removed from the plate 110. At this time, since the inclined surface 150b is formed on the upstream side (the rounded passage cover 105 side) of the lower end surface 150a of the guide plate 150, the rounded passage cover 105 can be tilted. The guide plate 150 can be smoothly pulled out without causing the guide belt 150 to interfere with the conveyor belt 103 even in a state where the guide plate 150 remains in the channel 121.

  As described above, in the lifting device 25 according to the embodiment of the present invention, a part of a foreign matter such as a nail or a bolt that has entered the rounded passage 121 is between the guide plate 150 and the pressing plate 151. Even when the gap S1 is larger than the gap S1, the pressing surface 151a constituting the pressing surface portion of the pressing plate 151 and its vicinity are elastically deformed, so that foreign matter can easily fit into the gap S1 between the guide plate 150 and the pressing plate 151. In addition, the foreign matter fitted in the gap S1 is sandwiched between the guide plate 150 and the pressing plate 151 by the elastic restoring force of the pressing plate 151, and is difficult to come out. It becomes difficult to be lifted with the following ball. Therefore, foreign matters can be retained in the rounded passage 121, so that it is possible to prevent the conveyance belt 103 from being damaged and obstructing the replenishment of the pachinko balls P to the pachinko machine 2.

  Further, in this embodiment, the pressing surface 151 a of the pressing plate 151 is provided so as to be partially deformable only in the deformation-permitting space portions 163 and 164 in the longitudinal direction of the rounded passage 121, thereby excessive deformation of the pressing plate 151. However, it may be provided so as to be deformable over the entire length of the rounded passage 121 according to the hardness of the pressing plate 151 or the like.

  In particular, in the ball introduction passage 123 for guiding the pachinko sphere to the round-shaped passage 121, unlike the snowboard rail 126, a foreign substance cannot be dropped, and the bottom surface of the passage is constituted by the bottom plate 141, so By feeding the foreign matter into the cylindrical passage 121, it is possible to prevent the foreign matter from being fitted into the ball introduction passage 123 in the ball introduction passage cover 106 fixed to the base plate 110 and cannot be taken out.

  Next, a rounded passage cover as a modification of the present invention will be described with reference to FIGS. 14A is a side view showing a pressing plate of an R-shaped passage cover as a first modification, FIG. 14B is a longitudinal sectional view of the pressing plate of FIG. 14A, and FIG. ) Is a GG end view of FIG. 15A is a side view showing a pressing plate of a rounded passage cover as a second modification, and FIG. 15B is an HH end view of FIG. 15A. FIG. 16A is a plan view showing a rounded passage cover as a third modification, FIG. 16B is a plan view showing a state in which a foreign object is fitted, and FIG. It is J end elevation.

  In the rounded path cover 105A as the first modification shown in FIG. 14, the guide plate 150 and the pressing plate 151 are made of a polycarbonate resin material. A pair of belt-like elastic portions 180a and 180b made of a hard urethane resin material are provided along the arc-shaped pressing surface 151a in the vicinity of the pressing surface 151a on both side surfaces of the pressing plate 151. Each of the pair of belt-like elastic portions 180a and 180b is formed in a belt plate shape having a predetermined vertical width (for example, about 15 mm) and a predetermined thickness (for example, about 3 mm), and the embodiment in the longitudinal direction of the pressing surface 151a. Are separately arranged at portions corresponding to the deformation allowable space portions 163 and 164.

  Specifically, the band-like elastic portions 180a and 180b are formed by recessing a part of the side surface of the pressing plate 151 into an arc-shaped belt shape, and fitting the band-plate-shaped elastic member into an arc-shaped concave portion whose side surface and upper surface are open. By combining, the surfaces of the belt-like elastic portions 180a and 180b and the surface of the pressing plate 151 made of a polycarbonate resin material are substantially flush with each other, and are disposed on both ends of the pressing surface 151a in the passage width direction. The pressing surfaces 180 c and 180 c (upper end surfaces) of the belt-like elastic portions 180 a and 180 b are provided together with the pressing surface 151 a of the pressing plate 151 so as to form a pressing surface portion that presses the pachinko ball against the transport belt 103. (See FIG. 14 (c)).

  In addition, through holes 181a and 181b that open to the side are formed below the belt-like elastic portions 180a and 180b in the pressing plate 151, so that the gap S1 is formed directly below the belt-like elastic portions 180a and 180b in the pressing plate 151. A wider space S <b> 2 is formed in the width direction of the rounded passage 121. Since these through holes 181a and 181b are extended downward from the lower ends of the belt-like elastic portions 180a and 180b, the through-holes 181a and 181b are formed between the guide plate 150 and the pressing plate 151 by elastic deformation of the belt-like elastic portions 180a and 180b. Since the foreign matter such as the screw B fitted in the gap S1 of the screw B easily falls into the space S2 formed by the through holes 181a and 181b directly below the screw B, the screw B is not easily transported together with the following ball. .

  Further, since the screw B pushed into the gap S1 falls and is accommodated in the space S2 as it is, the belt-like elastic portions 180a and 180b are elastically restored. For example, a part of the screw B caught in the gap S1. Does not protrude into the round path 121 and hinder the subsequent transfer of pachinko balls. Furthermore, since the through holes 181a and 181b are formed immediately below the elastic portion, the strength of the portion of the pressing plate 151 where the belt-like elastic portions 180a and 180b are provided is slightly reduced and is easily bent. It becomes easy.

  Further, since the lower ends of the through holes 181a and 181b are not extended and opened to the lower end of the pressing plate 151, if the pressing plate 151 is pulled upward, the screws B accommodated in the through holes 181a and 181b are It becomes possible to take out together with the pressing plate 151.

  In addition, the opening part of this invention may be a notch part extended from the lower end of an elastic part to the lower end of the press plate 151, and not only opening like opening 181a, 181b, but opening below. Further, if the space S2 wider in the passage width direction than the gap S1 can be formed, a bottomed opening concave portion that opens to the side even if it is not a through-hole penetrating the pressing plate 151 like the through-holes 181a and 181b. It may be.

  In the embodiment, the pressing plate 151 itself is made of a hard urethane resin material that is elastically deformable. However, the present invention is not limited to this, and at least the pressing plate 151 as in the first modification. If elastic portions (band-like elastic portions 180a and 180b) that can be elastically deformed are formed along the longitudinal direction of the pressing surface 151a on the side surface of the pressing surface 151a and the vicinity thereof, the entire pressing plate 151 is elastically deformed. 14C, the gap S1 formed between the opposing surfaces of the one guide plate 150 and the pressing plate 151 is expanded and foreign matter such as a screw B, as shown in FIG. Therefore, the same operation and effect as the rounded path cover 105 of the above embodiment can be obtained.

  That is, if the pressing surfaces 151c and 180c constituting the pressing surface portion together with the pressing surface 151a of the pressing plate 151 and a part of the side surface continuous to the pressing surfaces 180c and 180c are formed by the belt-like elastic portions 180a and 180b, the pachinko ball Since at least a part of the pressing surface portion (pressing surfaces 180c and 180c) for pressing the belt against the conveying belt 103 is elastically deformed, even if the entire pressing plate 151 is not elastically deformable, the guide plate 150 and The pachinko balls are easily fitted in the gap S1 between the pressing plate 151 and the pressing plate 151.

  Further, the elastic portion does not necessarily have to be formed continuously in the longitudinal direction of the rounded passage 121, and is partially formed at a predetermined position in the longitudinal direction of the rounded passage 121 like the strip-like elastic portions 180a and 180b. It may be formed. Further, the elastic portion does not necessarily extend from the pressing surface 151a on the side surface of the pressing plate 151 to the lower end of the pressing plate 151, and is provided only in the vicinity of the pressing surface 151a like the belt-like elastic portions 180a and 180b. It only has to be done.

  A round-shaped passage cover 105B as the second modification shown in FIG. 15 has a pressing plate 151A having upper and lower portions 151A ′ and 151A ″ made of a polycarbonate resin material and an upper portion 151A ″ with respect to the lower portion 151A ′. A belt-like elastic portion 151A ′ ″ made of a hard urethane resin material that is elastically deformable in the width direction of the passage.

In the above embodiment, the entire pressing plate 151 is made of a hard urethane resin material that can be elastically deformed, and by this, a part of the pressing plate 151 is deformed to make it easier to insert foreign matter. However, as in the second modification, at least an upper portion 151A ″ having a pressing surface 151a constituting a pressing surface portion of the pressing plate 151 is a part of the pressing plate 151 excluding the pressing surface 151a ( It is formed so as to be elastically deformed so as to be swingable in the width direction of the rounded passage 121 with a horizontally extending elastic portion 151A ′ ″ formed at a substantially central position in the vertical direction) as a fulcrum. if 151a is elastically deformable formed between the guide plates 150 and 150 adjacent, as indicated in FIG. 15 (b), formed between the facing surfaces of one of the guide plate 150 and the pressing plate 151 Gap S1, which is pushed open, easily fitted foreign matter such as screws B.

  Therefore, even when a part of the foreign matter such as the screw B entering the rounded passage 121 is larger than the gap S1 between the guide plate 150 and the pressing plate 151, the pressing plate 151 excluding the pressing surface 151a A certain elastic part 151A ′ ″ is elastically deformed, and the upper part 151A ″ having the pressing surface 151a on the upper part thereof moves in the width direction of the rounded passage 121, so that foreign matter is easily fitted in the gap S1, and The foreign matter fitted in the gap S1 is sandwiched between the upper portion 151A ″ and the guide plate 150 by the elastic restoring force of the elastic portion 151A ′ ″ and becomes difficult to be removed. It becomes difficult to be lifted with the succeeding ball. Accordingly, since foreign matter can be retained in the rounded passage 121, it is possible to prevent the conveyance belt 103 from being damaged and obstructing the replenishment of the pachinko balls to the pachinko machine 2.

  In this case, the elastic portion 151A ″ ″ constitutes an elastic portion that elastically returns the upper portion 151A ″ having the pressing surface 151a to a fixed position. Further, since the upper portion 151A ″ has a through hole 169a having a diameter larger than that of the through pin 165a, the upper portion 151A ″ is allowed to swing in the passage width direction with the elastic portion 151A ′ ″ as a fulcrum. In addition, an annular ring 171 made of an elastic material is fitted between the through hole 169a and the through pin 165a so that the upper portion 151A '' can be supported.

  In the second modification, the elastic portion 151A ′ ″ is formed in the horizontal direction at a substantially central position in the vertical direction of the flat portion of the pressing plate 151. However, the position and orientation of such an elastic portion are formed. However, as long as the pressing surface portion can be moved in the width direction of the rounded passage 121, the formation position and orientation thereof can be variously changed.

In the rounded path cover 105C as the third modification shown in FIG. 16, the pressing plate 151C is made of a polycarbonate resin material, and is provided so as to be movable in the path width direction with respect to the adjacent guide plates 150 and 150. In other words, the pressing surface 151a is formed between the adjacent guide plates 150 and 150 so as to be elastically deformable, and further between the guide plates 150 and 150 by the coil springs 172 and 172 as holding portions fitted and inserted into the through pins 165a. It is provided in a fixed position so that it can be elastically returned.

  As described above, the pressing plate 151C, that is, the pressing surface 151a constituting the upper end surface thereof is slidable in the width direction of the rounded passage 121, and can be elastically returned to a predetermined position by the coil springs 172 and 172 as holding portions. If provided, as shown in FIGS. 16 (b) and 16 (c), a part of the gap S1 formed between the opposing surfaces of the guide plate 150 and the pressing plate 151C is expanded, such as a screw B or the like. Since foreign substances are easily fitted, the same operation and effect as the rounded path cover 105 of the above embodiment can be obtained.

  Also in this modified example 3, by forming an opening (not shown) from the vicinity of the pressing surface 151a (bottom surface) of the pressing plate 151C downward, the pressing plate 151C has a pressing surface 151a directly below. Since a space S2 wider in the passage direction than the gap S1 between the guide plate 150 and the pressing plate 151C is formed, the sliding movement of the pressing plate 151C in the passage width direction causes the space between the guide plate 150 and the pressing plate 151C. The foreign matter such as the screw B fitted in the gap S1 is easily dropped as it is into the space S2 formed in the opening immediately below.

  Therefore, even when a part of the foreign matter such as the screw B entering the rounded passage 121 is larger than the gap S1 between the guide plate 150 and the pressing plate 151, the elastic force of the coil springs 172 and 172 serving as the holding portions is increased. When the pressing plate 151 moves against the rounded passage 121 in the width direction, the foreign matter is easily fitted in the gap S1, and the foreign matter fitted in the gap S1 is pressed by the elastic return force of the coil springs 172 and 172. By being sandwiched between the plate 151 and the guide plate 150 and being difficult to come off, even when pushed by a subsequent game ball, it becomes difficult to be lifted together with the subsequent ball. Accordingly, since foreign matter can be retained in the rounded passage 121, it is possible to prevent the conveyance belt 103 from being damaged and obstructing the replenishment of the pachinko balls to the pachinko machine 2.

  Further, in the third modification, the pressing plate 151 is held at a fixed position between the adjacent guide plates 150 and 150 by the coil spring 172. However, as long as the pressing plate 151 can be held at a fixed position by an elastic force. The holding portion is not limited to the coil spring, and the holding portion may be constituted by, for example, a leaf spring, a urethane material, a rubber material, or the like.
