  When the above-described payout condition is satisfied, the screw 52 is rotationally driven by the stepping motor 51, and the lowermost game ball of the game ball row in the guide rod 40 moves downward along the rotation of the spiral protruding wall 52R. When the lower end of the spiral protruding wall 52 </ b> R moves away from the payout passage 55, the lowermost game ball flows down below the screw 52. When a predetermined number of game balls are paid out, the rotation of the screw 52 stops, and the game ball is dammed again on the spiral protruding wall 52R. Note that the number of game balls to be paid out is controlled by the number of rotations of the screw 52.

  The engagement lever 59 is operated when the game ball is removed from the pachinko gaming machine 10. Specifically, when the engagement lever 59 is slid upward and the first and second movable members 57 and 58 are released, the first movable member 57 can be rotated, so that the game ball is attached to the screw 52. According to the inclination of the spiral protruding wall 52R, it goes to the right and falls onto the second movable member 58 that has fallen to the left. Then, the game ball is guided to the ball removal passage 50T by being guided by the second movable member 58.

  By the way, as shown in FIG. 11, the stepping motor 51 is covered with a metal plate 60 (corresponding to the “metal member” of the present invention). The metal plate 60 is curved along the outer periphery of the motor main body 51A of the stepping motor 51, and extends from the rear end of the curved portion 60A and is flat on the rear side surface of the control unit 51B. And an upper end portion 60C bent forward from the upper end of the flat portion 60B. The metal plate 60 is fixed to be non-rotatable by the flat portion 60B being sandwiched between the control portion 51B of the stepping motor 51 and the inner cover 50B. Further, the upper end portion 60C of the metal plate 60 is folded back from the flat portion 60B along the support plate 50E, and the upper end portion of the flat portion 60B is supported by the support plate in a state where the upper end portion 60C is overlapped with the support plate 50E. The metal plate 60 is fixed in the dispensing device 50 by being sandwiched between the end face of 50E and the inner cover 50B. Further, by fixing the metal plate 60, the stepping motor 51 covered with the metal plate 60 is more firmly held.

  As shown in FIG. 10, the bulge receiving portion 50G that covers the stepping motor 51 in the inner cover 50B is formed with two holes 50S and 50S extending in the vertical direction, and the outer cover 50C is further formed in the outer cover 50C. A square through hole 50Z is formed so as 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 grounded.

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

  A group of game balls supplied from the game ball circulation system is arranged in one row and one stage by the inclined rod 30 and introduced into the guide rod 40, and flows down the guide rod 40 and is guided to the payout device 50. Here, in the pachinko gaming machine 10 of the present embodiment, since the guide rod 40 has a single-row structure, the pachinko gaming machine 10 as a whole is made more compact than those in which the guide rod 40 has a two-row structure. be able to. Further, if the guide rod 40 has a one-row structure, it is conceivable that the feeding speed of the game balls to the payout device 50 is lower than that of the two-row structure, but in this embodiment, the guide rod 40 extends in the vertical direction. 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 feeding speed of the game balls.

  The game ball train guided to the guide basket 40 flows into the payout device 50. Here, the screw 52 in the payout device 50 is always stopped, and the game ball is dammed between the screw 52 and the first movable member 57. When a payout condition such that a game ball wins a winning opening is established, the stepping motor 51 rotates the screw 52 to pay out the game ball to the upper plate 26.

  By the way, in the pachinko gaming machine 10 of this embodiment, since the guide rod 40 has a single-row structure instead of a two-row structure, the screw 52 and the stepping motor 51 can be reduced in size, but the stepping motor 51 is reduced in size. Then, it can be considered that the load on the stepping motor 51 increases. Further, in order to prevent a decrease in the payout speed due to the induction rod 40 being changed from the two-row structure to the one-row structure, it is necessary to increase the rotation speed of the screw 52, and thus it is considered that the load on the stepping motor 51 increases.

  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 due to overheating or the like may occur, but in the pachinko gaming machine 10 of the present embodiment, Since the metal plate 60 is disposed between the stepping motor 51 and the inner cover 50 </ b> B and a part of the metal plate 60 is exposed to the outside of the dispensing device 50, the heat of the stepping motor 51 is discharged through the metal plate 60. 50 can be efficiently discharged to the outside. Thereby, overheating of the payout device 50 is suppressed, and it becomes possible to pay out the game ball stably.

  Moreover, since the metal plate 60 not only has a heat dissipation function but also serves as a metal holder that surrounds and holds the stepping motor 51 from the side, it has a more compact configuration than those provided separately. can do. Further, the metal plate 60 is grounded and can be used as a shield for protecting the electric drive source from noise.

  Further, since the bulge receiving portion 50G for receiving the stepping motor 51 by bulging only a part of the inner cover 50B in the payout device 50 is provided, it is not necessary to enlarge the entire payout device 50. Further, since the hole is formed in the bulging receiving portion 50G, the heat of the stepping motor 51 can be efficiently discharged out of the dispensing device 50.
