In a state where the drive motor 121 is fixed to the mounting surface 122A, the output shaft 121A of the drive motor 121 protrudes rearward of the mounting surface 122A through the circular opening 122B.

  The output shaft 121A of the drive motor 121 is provided with a connecting member 123 that connects the output shaft 121A and the base drum 131. The connecting member 123 includes a cylindrical insertion portion 123A through which the output shaft 121A can be inserted, and a flange portion 123B that extends in the radial direction at the end of the insertion portion 123A. The insertion portion 123A of the connecting member 123 is fixed to the output shaft 121A, and the flange portion 123B of the connecting member 123 is fixed to the closed end surface 131A of the base drum 131. In a state where the flange 123B is fixed to the closed end surface 131A, the insertion portion 123A of the connecting member 123 passes through the circular hole 131B formed at the center of the closed end surface 131A and protrudes rearward of the closed end surface 131A.

  Thus, almost the entire drive motor 121 is accommodated in the base drum 131 of the rotating body 130, and the base drum 131 rotates around the output shaft 121 </ b> A based on the drive force of the drive motor 121.

  The bracket 122 on which the drive motor 121 is installed is fixed to the front inner wall portion 113 of the cover member 110 so that the rotating body 130 is positioned in the cover member 110. A through hole 113A (see FIG. 4) is formed at a substantially central position of the front inner wall portion 113, and a through hole 114A (see FIG. 4) is formed at a substantially central position of the rear inner wall portion 114. In a state where the bracket 122 is fixed to the front inner wall 113, the output shaft 121A of the drive motor 121 and the insertion portion 123A of the connecting member 123 pass through the through hole 114A and protrude rearward, and the end of the drive motor 121 is the through hole. It protrudes forward through 113A.

  The game ball lifting device 100 configured as described above attracts the game ball that has been rolling on the upstream first transport rod 21 to the outer peripheral surface of the rotating body 130 by the magnetic force of the magnet 133, and attracts the game ball that has been attracted. Is transported by the rotating body 130 and supplied to the first conveying rod 21 on the downstream side (see FIG. 10).

  As shown in FIGS. 2A and 9, the game ball lifting device 100 is disposed corresponding to the receiving port 111, and guides the game ball supplied from the first transport rod 21 on the upstream side into the cover member 110. It further includes a supply guide 151 and a discharge guide 152 that is disposed corresponding to the discharge port 112 and guides the game ball lifted by the rotating body 130 to the first transport rod 21 on the downstream side.

  The supply guide 151 is a plate-like member, and the upper surface of the supply guide 151 is formed as a rolling surface 151A on which a game ball can roll. The supply guide 151 is supported by the front inner wall portion 113 and the rear inner wall portion 114.

  The front inner wall portion 113, the rear inner wall portion 114, and the supply guide 151 form a supply passage that guides the game ball from the upstream first transfer rod 21 to the rotating body 130. The supply passage and the first transfer rod The 21 guide rod 21C is in communication.

  The supply guide 151 is disposed to be inclined downward from the guide rod 21 </ b> C of the first transport rod 21 toward the rotating body 130. The inclination angle of the supply guide 151 is set larger than the inclination angle of the guide rod 21 </ b> C of the upstream first conveyance rod 21. The downstream end portion of the rolling surface 151A of the supply guide 151 faces the outer peripheral surface of the rotating body 130 (cover sheet 134) with a gap through which game balls cannot pass. Thereby, the fall of the game ball which rolls the supply guide 151 can be prevented.

  The discharge guide 152 is a plate-like member, and the upper surface of the discharge guide 152 is formed as a rolling surface 152A on which a game ball can roll. The discharge guide 152 is supported by the front inner wall 113 and the rear inner wall 114.

  The front inner wall 113, the rear inner wall 114, and the discharge guide 152 form a discharge passage for discharging the game ball lifted by the rotating body 130 to the first transport rod 21 on the downstream side. The first conveying rod 21 communicates with the common rod 21A.

  The discharge guide 152 is disposed to be inclined downward from the rotating body 130 toward the common rod 21A of the first conveying rod 21 on the downstream side. The inclination angle of the discharge guide 152 is set smaller than the inclination angle of the common rod 21 </ b> A of the first transport rod 21. The first transport rod 21 on the downstream side is formed so as to be inclined at a minimum angle that allows the game ball to roll under its own weight. Therefore, the first transport rod 21 is formed to be inclined smaller than the first transport rod 21 on the downstream side. The discharge guide 152 may be formed at an angle at which the game ball cannot roll only with its own weight.

  However, since the game balls are successively conveyed from the rotating body 130 to the discharge guide 152, the game balls are pushed and rolled by the game balls conveyed from behind. Therefore, even if the inclination of the discharge guide 152 is an angle at which the game ball cannot roll only by its own weight, the game ball rolls to the first transport rod 21 on the downstream side.

  The upstream end of the discharge guide 152 is formed so as to be in sliding contact with the outer peripheral surface of the rotating body 130. The game ball that is attracted to and transported by the outer peripheral surface of the rotating body 130 is guided away from the outer peripheral surface of the rotating body 130 onto the rolling surface 152A of the discharging guide 152 by contacting the upstream end of the discharging guide 152. Then, it is guided to the first conveying rod 21 on the downstream side.

  The upstream end portion of the discharge guide 152 is not brought into sliding contact with the outer peripheral surface of the rotating body 130, but is made close to the outer peripheral surface of the rotating body 130 with a step (gap) that can be overcome by the game ball. Good.

  Next, with reference to FIGS. 10 to 12, the lifting of the game ball by the game ball lifting device 100 will be described.

  FIG. 10 is a side view of the game ball lifting device 100 from the front of the game island 1. FIG. 11 is a view showing the outer peripheral surface of the rotating body 130 of the game ball lifting device 100. FIG. 12 is a perspective view of the vicinity of the receiving port 111 of the game ball lifting device 100.

  As shown in FIG. 10, the game ball rolling from the upstream first transport rod 21 is guided to the downstream end of the supply guide 151 through the receiving port 111 of the cover member 110.

  The game ball that has reached the vicinity of the outer peripheral surface of the rotating body 130 by the supply guide 151 is attracted to the outer peripheral surface of the rotating body 130 by the magnetic force of the magnet 133 of the rotating body 130. Since the rotating body 130 is rotated clockwise by the drive motor 121, the game balls at the downstream end of the supply guide 151 are successively attracted to the outer peripheral surface of the rotating body 130, and are moved upward along with the rotation of the rotating body 130. To be lifted.

  The lifted game ball is guided on the rolling surface 152A of the discharge guide 152 away from the outer peripheral surface of the rotating body 130 by contacting the upstream end of the discharge guide 152 that is in sliding contact with the outer peripheral surface of the rotating body 130. Is done. The game ball guided in this manner rolls on the discharge guide 152 and is guided to the upstream end portion of the first transport rod 21 on the downstream side through the discharge port 112.

  As shown in FIG. 11, the game ball that has reached the downstream end of the supply guide 151 is attracted by the width direction end portions 141 and 142 of the two magnets 133 constituting the magnet group 140 and the connecting portion 143 of these magnets 133. Is done. The reason why the game balls are attracted in this way is that the magnetic flux density increases at the width direction end portions 141 and 142 of the two magnets 133 of the magnet group 140 and the connecting portion 143 of these magnets 133.

  The game balls of the supply guide 151 are attracted to the magnets 133 of the magnet groups 140 one after another as the rotating body 130 rotates and are transported to the discharge guide 152. Since the game ball attracted to the magnet 133 is magnetized, other game balls may be attracted to the magnetized game ball. In such a case, not only the game balls are lifted one by one as shown in FIG. 11, but also a plurality of game balls are adsorbed in a bead shape in the circumferential direction of the rotating body 130 and lifted to the discharge guide 152. Is done.

  The game balls of the supply guide 151 are attracted by the width direction end portions 141 and 142 of the two magnets 133 disposed in the holding portion 132A and the connecting portion 143. Therefore, at the downstream end portion of the supply guide 151, the width direction Dust and dust attached to the game ball tend to accumulate at positions corresponding to the end portions 141 and 142 and the connecting portion 143. When dust or dirt accumulates in the supply guide 151 in this way, the accumulated dust or dirt reattaches to the game ball, which causes a failure of various devices such as the game ball lifting device 100.

  Therefore, in the game ball lifting device 100, a slit 151B is formed at the downstream end of the supply guide 151 as shown in FIG.

  The slits 151 </ b> B are formed at positions corresponding to the width direction end portions 141 and 142 and the connecting portion 143 of the two magnets 133 constituting the magnet group 140 at the downstream end portion of the supply guide 151. These three slits 151B are formed so as to penetrate the upper and lower surfaces of the supply guide 151 and extend in the rolling direction of the game ball.

  Dust and dust separated from the game ball rolling the supply guide 151 and the game ball lifted by the rotating body 130 pass through the slit 151B and fall below the supply guide 151. Dust and dust accumulation can be suppressed. Since the slit 151B is provided in correspondence with the position where the game ball is attracted to the rotating body 130, it is possible to efficiently reduce the accumulation of dust and dirt peeled off from the game ball. Note that a tray for receiving dust or dust may be provided below the slit 151.

  Each slit 151 </ b> B also functions as a guide groove for guiding the game ball rolling on the rolling surface 151 </ b> A of the supply guide 151 to the width direction end portions 141 and 142 and the connecting portion 143 of the magnet 133. Therefore, the game ball of the supply guide 151 can be guided to the suction position of the rotating body 130 by the slit 151B.

  Further, in the game ball lifting device 100, the magnet group 140 of the rotating body 130 is configured by arranging two magnets 133 in the width direction, but as shown in FIG. 13A, three magnets 133 are arranged in the width direction. Alternatively, the four magnets 133 may be arranged side by side in the width direction as shown in FIG.

  13A and 13B, in one magnet group 140, the magnets 133 arranged in the width direction are arranged so that the outer magnetic poles are alternately different. In the adjacent magnet group 140, the magnets 133 arranged in the circumferential direction are arranged so that the outer magnetic poles are alternately different. By configuring the magnet group 140 with the plurality of magnets 133 in this way, it is possible to attract more game balls to the outer peripheral surface of the rotating body 130, and to increase the efficiency of lifting the game balls by the rotating body 130. Become.

  As shown in FIG. 13C, when the magnet group 140 is configured by four magnets 133, the supply guide 151 includes the width direction end portions 141 and 142 of the four magnets 133 that configure the magnet group 140. And the slit 151B is formed in the position corresponding to each connection part 143 of these magnets 133. FIG.

  By the way, when the operating rate of each gaming machine is low, the gaming balls may stay in the first transport rod 21 or the discharge guide 152 on the downstream side connected to the gaming ball lifting device 100. Therefore, as shown in FIGS. 9 and 14A to 14C, the game ball lifting device 100 detects that the discharge guide 152 is filled with game balls and is in an overflow state. A sensor 161 is provided. 14A shows a state where game balls are not staying in the discharge guide 152, and FIG. 14B shows an overflow state of the discharge guide 152. FIG. 14C shows the switch portion 161 </ b> A of the overflow sensor 161.

  As shown in FIGS. 9 and 14C, the overflow sensor 161 is provided between the front inner wall 113 and the front outer wall 115 of the cover member 110 in correspondence with the discharge guide 152.

  The switch portion 161 </ b> A of the overflow sensor 161 faces the inside of the cover member 110 through an opening 113 </ b> B formed in the upper portion of the front inner wall portion 113. A notch 152B is formed on the side of the discharge guide 152, and the overflow sensor 161 is provided so that the switch 161A is positioned in the notch 152B. The gap between the switch portion 161A and the discharge guide 152 is set to a gap that prevents the game ball rolling on the rolling surface 152A of the discharge guide 152 from passing.

  The electrical wiring 161B connected to the overflow sensor 161 is guided into the cover member 110 through an opening 113C formed in the lower portion of the front inner wall 113, and extends downward through the lower surface opening of the cover member 110. (See FIG. 9).

  As shown in FIG. 14C, the switch portion 161A of the overflow sensor 161 is disposed so as to straddle the discharge guide 152 up and down. The substantially upper half of the switch part 161A is located above the rolling surface 152A, and the substantially lower half of the switch part 161A is located below the rolling surface 152A. Since a part of the switch part 161A is located below the discharge guide 152 as described above, the switch part 161A can be operated from the lower surface opening of the cover member 110 during maintenance of the game ball lifting device 100. Therefore, it is possible to easily check without removing the overflow sensor 161 from the cover member 110.

  Next, the detection of the overflow state of the discharge guide 152 by the overflow sensor 161 will be described with reference to FIGS.

  When the operating rate of each gaming machine is high, a lot of gaming balls are supplied to each gaming machine. Therefore, as shown in FIG. The ball hardly stays.

  On the other hand, when the operating rate of each gaming machine is remarkably lowered, almost no gaming balls are supplied to each gaming machine, and as shown in FIG. It stays in the discharge guide 152. When the game ball is thus filled in the discharge guide 152, the switch 161A of the overflow sensor 161 is pressed by the game ball, so that an overflow signal is output from the overflow sensor 161. By detecting this overflow signal, the overflow state of the discharge guide 152 can be detected.

  When an overflow signal is detected, the rotation of the rotating body 130 of the game ball lifting device 100 is stopped.

  According to the game ball lifting device 100 described above, the following effects can be obtained.

  At the downstream end portion of the supply guide 151 of the game ball lifting device 100, slits 151B are formed at positions corresponding to the width direction end portions 141 and 142 and the connecting portion 143 of the two magnets 133 constituting the magnet group 140, respectively. Is done. Since these slits 151B are formed so as to penetrate the upper and lower surfaces of the supply guide 151, the dust or dirt peeled off from the game ball rolling the supply guide 151 or the game ball lifted by the rotating body 130, etc. Can be dropped below the supply guide 151 via the slit 151 </ b> B, and dust and dust can be prevented from accumulating on the supply guide 151. In addition, since the slit 151B is provided corresponding to the position where the game ball is attracted to the rotating body 130, it is possible to efficiently reduce the accumulation of dust and dust that has been peeled off from the game ball.

(Second Embodiment)
With reference to FIG. 15, the game ball lifting apparatus 100 according to the second embodiment will be described. FIG. 15 is a side view of the game ball lifting device 100 according to the second embodiment when viewed from the rear of the game island 1.

  The game ball lifting device 100 according to the second embodiment has substantially the same configuration as that of the first embodiment, but differs in the configuration of the rotating body 130. Hereinafter, the difference will be mainly described.

  In 2nd Embodiment, the outer peripheral surface of the rotary body 130 of the game ball lifting apparatus 100 is formed in unevenness over the circumferential direction. By setting the thickness of the magnet guide 132 to be thinner than the thickness of the magnet 133, or by directly adhering the magnet 133 to the base drum 131 without using the magnet guide 132, the circumferential direction of the outer peripheral surface of the rotating body 130 It is possible to alternately form the convex portions 130A and the concave portions 130B. Therefore, the convex portion 130 </ b> A on the outer peripheral surface of the rotating body 130 is configured by the magnet 133.

  In the second embodiment, the position where the magnet 133 is disposed is the convex portion 130A on the outer peripheral surface of the rotating body 130, but the thickness of the magnet 133 is set to be thinner than the thickness of the magnet guide 132. Thus, the position where the magnet 133 is disposed may be the recess 130 </ b> B on the outer peripheral surface of the rotating body 130.

  According to the game ball lifting device 100 described above, the following effects can be obtained.

  Since the convex portions 130A and the concave portions 130B are alternately formed in the circumferential direction on the outer circumferential surface of the rotating body 130 of the game ball lifting device 100, the game balls guided into the concave portions 130B are placed in the upper corner portions of the convex portions 130A. It can be transported in a state where it is placed on (hooked). This makes it possible to reliably lift the game ball adsorbed on the rotating body 130.

  Further, since the convex portion 130A on the outer peripheral surface of the rotating body 130 is configured by the magnet 133, the game ball guided into the concave portion 130B can be firmly adsorbed at the upper corner portion of the convex portion 130A, and the game ball can be more attracted. It is possible to reliably lift.

(Modification)
The game ball lifting device 100 according to the first and second embodiments can remove illegal balls used for illegal purposes by adopting the configurations of Modification 1 and Modification 2 described below. .

  First, with reference to FIG. 16 (A) and FIG. 16 (B), the modification 1 of the game ball lifting apparatus 100 by 1st and 2nd embodiment is demonstrated. 16A is a side view of the game ball lifting device 100, and FIG. 16B is an enlarged view of a broken line area portion of the game ball lifting device 100 of FIG. 16A.

  In the gaming machine, there is a case where fraud that increases the winning rate to the start winning opening or the like is performed by using an irregular small-diameter sphere having a smaller diameter than a regular gaming ball.

  Therefore, in the game ball lifting device 100 according to the first modification, as shown in FIGS. 16A and 16B, the outermost periphery 151C of the supply guide 151 and the outer periphery of the rotating body 130 (cover sheet 134). The gap D1 with the surface is set slightly smaller than the diameter of the regular game ball. As a result, the regular game ball cannot pass through the gap D1, and only the illegally small-diameter sphere passes through the gap D1 and is discharged from the most downstream portion 151C of the supply guide 151 to the lower side of the game ball lifting device 100. become.

  Below the gaming ball lifting device 100, a collection box 170 capable of collecting the discharged illegal small-diameter balls is provided. Therefore, even if a plurality of illegal small-diameter spheres are used, the illegal small-diameter spheres can be stored in the collection box 170. Further, if the collection box 170 is provided below the slit 151B, the collection box 170 can collect dust and dust falling from the slit 151B.

  According to the gaming ball lifting device 100 described in the first modification, the illegal small-diameter ball can be collected in the collection box 170, and the occurrence of the illegal act in the gaming machine can be suppressed.

  Next, with reference to FIGS. 17-19, the modification 2 of the game ball lifting apparatus 100 by 1st and 2nd embodiment is demonstrated.

  FIG. 17A is a side view of the game ball lifting device 100 according to the second modification, and FIG. 17B is an enlarged view of a broken line region portion of the game ball lifting device 100 of FIG. 18A is a perspective view of the vicinity of the receiving port 111 of the game ball lifting device 100, and FIG. 18B is a plan view of the supply guide 151. FIG. FIG. 19A to FIG. 19D are diagrams illustrating a mechanism for collecting illegal large-diameter spheres.

  In the gaming machine, an illegal large-diameter ball having a larger diameter than that of a regular game ball is used to block the passage that is difficult to enter the start winning opening, thereby causing the game ball to be guided to a route that easily enters the starting winning opening. Sometimes.

  Therefore, in the game ball lifting device 100 according to the modified example 2, as shown in FIGS. 17A and 17B, the lowermost portion 118A of the upstream side wall portion 118 and the outer periphery of the rotating body 130 (cover sheet 134). The gap D2 with the surface is set slightly larger than the diameter of the regular game ball.

  Thereby, only the regular game balls out of the game balls adsorbed on the outer peripheral surface of the rotating body 130 pass through the gap D <b> 2 and are transported to the discharge guide 152. Since the illegal large-diameter sphere cannot pass through the gap D2, it comes off from the rotating body 130 and falls after contacting the lowermost portion 118A of the upstream side wall 118. The illegal large-diameter sphere dropped from the rotating body 130 is collected in the collection box 182 (see FIG. 18A) via the collection passage 181.

  As shown in FIGS. 18A and 18B, the game ball lifting device 100 includes a collection passage 181 in the supply guide 151.

  The collection passage 181 is a passage that extends in the vertical direction so as to penetrate the upper and lower surfaces of the supply guide 151 and is a passage through which an illegal large-diameter sphere can pass. The collection passage 181 is disposed so as to be located at the approximate center in the width direction of the supply guide 151 and below the upstream side wall 118.

  As shown in FIG. 18 (B), the collection passage 181 has a substantially pentagonal cross section. Since the collection passage 181 is arranged so that the corners face upstream, even if the collection passage 181 is provided at the center in the width direction of the supply guide 151, the flow of the game ball rolling on the supply guide 151 is almost obstructed. There is nothing to do.

  As shown in FIG. 18A, the supply guide 151 protrudes from the receiving port 111 of the cover member 110 to the outside. The supply guide 151 includes a side wall 151D protruding upward at a portion outside the cover member 110, and the upper receiving port 181A of the recovery passage 181 is set at a position higher than the side wall 151D. Below the supply guide 151, a collection box 182 for collecting the illegal large-diameter sphere discharged from the lower discharge port 181B (see FIG. 19D) of the collection passage 181 is disposed. Therefore, even if a plurality of illegal large-diameter spheres are used, the illegal large-diameter spheres can be stored in the collection box 182.

  Note that the lowermost portion 118A of the upstream side wall portion 118 is formed as a triangular cutout portion so as to be separated from the rolling surface 151A of the supply guide 151 from the end in the width direction toward the center. A corner portion 118B of the lowermost portion 118A of the upstream side wall portion 118 is located immediately above the upper receiving port 181A of the recovery passage 181.

  With reference to FIG. 19 (A) to FIG. 19 (D), the collection of illegal large-diameter balls by the game ball lifting device 100 will be described.

  When the illegal large-diameter sphere is guided to the downstream end of the supply guide 151, the illegal large-diameter sphere is adsorbed on the outer peripheral surface of the rotating body 130. As shown in FIG. 19A, when the irregularly large-diameter sphere being lifted comes into contact with the lowermost portion 118A of the upstream side wall portion 118, it remains along the lowermost portion 118A while being adsorbed on the outer peripheral surface of the rotating body 130. To the corner 118B. As shown in FIG. 19B, when the rotating body 130 rotates with the illegal large-diameter sphere reaching the corner 118B of the lowermost part 118A, the illegal large-diameter sphere moves to a position where it is removed from the magnet 133 of the rotating body 130. Then, it falls downward from the outer peripheral surface of the rotating body 130.

  The dropped illegal large-diameter sphere flows into the recovery passage 181 from the upper receiving port 181A as shown in FIG. 19C, and passes through the recovery passage 181 and passes through the lower discharge port 181B as shown in FIG. 19D. Guided into collection box 182.

  According to the gaming ball lifting device 100 described in the second modification, the illegal large-diameter sphere can be collected in the collection box 182 via the collection passage 181 and it is possible to suppress the occurrence of fraud in the gaming machine. .

  It should be noted that the present invention is not limited to the above-described embodiments and modifications, and it is obvious that various modifications can be made within the scope of the technical idea.

  In the game ball lifting device 100 according to the first and second embodiments, the slit 151B is formed in the supply guide 151, but the width direction ends of the two magnets 133 constituting the magnet group 140 also at the upstream end of the discharge guide 152. You may form a slit in the position corresponding to the parts 141 and 142 and the connection part 143. FIG. If slits are formed in both the supply guide 151 and the discharge guide 152, dust and dust accumulation can be more efficiently reduced.

  In the first and second embodiments, the slit 151 </ b> B is formed as a notch penetrating the upper and lower surfaces of the supply guide 151, but may be formed as a groove recessed in the supply guide 151.

  The present invention is not limited to pachinko gaming machines, and can be applied to all gaming machines that use gaming balls such as, for example, arrange ball gaming machines, sparrow ball gaming machines, and slot machines.
