The metal plate 60 is fixed in the dispensing device 50 by being held between the end face 50E and the inner cover 50B. Further, by fixing the metal plate 60, the stepping motor 51 covered by the metal plate 60 is held more firmly.

  Further, as shown in FIG. 10, in the bulging receiving portion 50G of the inner cover 50B covering the stepping motor 51, two holes 50S, 50S extending in the vertical direction are formed, and further, the outer cover 50C The square through hole 50Z is formed to expose the bulging receiving portion 50G (see FIG. 8). Thereby, the metal plate 60 is exposed to the outside. The metal plate 60 is connected to ground.

  The configuration of the pachinko gaming machine 10 of the present embodiment is as described above. Next, the operation and effect of the pachinko gaming machine 10 of the present embodiment will be described.

  The game ball groups supplied from the game ball circulation system are aligned in a single row by the inclined rod 30 and introduced into the induction rod 40 and flowed down the induction rod 40 and guided to the payout device 50. Here, in the pachinko gaming machine 10 of the present embodiment, since the induction rods 40 have a single-row structure, the entire pachinko gaming machine 10 can be made more compact than those in which the induction rods 40 have a two-row structure. be able to. In addition, it is conceivable that the feeding speed of gaming balls to the payout device 50 is lower than that of the two-row structure if the guiding rod 40 has a one-row structure, but in the present embodiment, it extends in the vertical direction to the guiding rod 40 Since the straight portions (the first flow path 41 and the third flow path 43) are provided, it is possible to prevent a decrease in the feed speed of the game balls.

  The game ball row induced by the induction rod 40 flows into the payout device 50. Here, the screw 52 in the payout device 50 is always stopped, and the gaming ball is held between the screw 52 and the first movable member 57. Then, when a payout condition such as a game ball winning in the winning opening is satisfied, the stepping motor 51 rotationally drives the screw 52 and the game ball is paid out to the upper plate 26.

  By the way, in the pachinko gaming machine 10 of the present embodiment, since the induction rods 40 do not have a two-row structure but have a one-row structure, the screws 52 and the stepping motor 51 can be miniaturized. Then, it is conceivable that the load of the stepping motor 51 increases. Further, in order to prevent the decrease in the discharge speed due to the two-row structure of the induction rods 40 from the one-row structure, it is considered that the load of the stepping motor 51 increases because it is necessary to increase the rotational speed of the screw 52.

  Here, if the load on the stepping motor 51 increases due to the downsizing and speeding up of the stepping motor 51 of the payout device 50, there is a concern that an abnormality may occur due to overheating or the like, but in the pachinko gaming machine 10 of this embodiment, Since metal plate 60 is disposed between stepping motor 51 and inner cover 50B and a part of metal plate 60 is exposed to the outside of dispensing device 50, the heat of stepping motor 51 is dissipated through metal plate 60. It can be discharged efficiently out of 50. Thereby, the overheating of the payout device 50 is suppressed, and it becomes possible to stably pay out the game balls.

  Further, the metal plate 60 not only has a heat radiation function but also serves as a metal holder for surrounding and holding the stepping motor 51 from the side, so that the configuration is more compact than that provided separately. can do. Furthermore, the metal plate 60 is grounded and can also be used as a shield to protect the electrical drive source from noise.

  Further, since only a part of the inner cover 50B in the dispensing device 50 is bulged outward to provide the bulging receiving portion 50G for receiving the stepping motor 51, there is no need to enlarge the entire dispensing device 50. Further, by forming the hole in the bulging receiving portion 50G, the heat of the stepping motor 51 can be efficiently discharged to the outside of the dispensing device 50.
