In the above-described embodiment, the configuration in which the guided portion 95 is provided in the lower passage member 25 has been described. However, the guided portion 95 may be provided in the back set board 20.

  Thus, the game ball payout operation by the ball payout device 50 attached to the back set board 20 is performed based on a command signal output from a ball payout control board (not shown) under a predetermined condition. In the following, this payout operation will be described. First, the game balls supplied from the alignment waiting passage 23a into the ball payout device 50 through the receiving port 52 reach the ball feeding member 60 through the receiving passage 56 of the guide passage 55, as shown in FIG. When the ball feeding member 60 is received in the receiving portion 63, the ball feeding member 60 is in a standby state in which the ball feeding member 60 is restricted from flowing down to the payout passage 57. At this time, the pressure caused by the weight of the game ball located on the upstream side is weighted on the downstream side by the upper bent portion 56a of the receiving passage 56 so that the pressure acting on the ball feeding member 60 does not become excessive pressure. It is reduced. Further, the direction of introduction of the game ball into the ball feeding member 60 is set obliquely with respect to the vertical direction so as to be along the rotational tangential direction of the ball feeding member 60 by the lower bent portion 56b.

  The alignment standby passage 23a formed in the upper passage member 23 is provided so as to extend vertically at the right side edge of the back surface of the back set board 20 as described above. As shown in FIG. A plurality of convex protrusions 23b are formed at predetermined intervals on the inner surfaces of the left and right passage walls of 23a, and the arrangement of the protrusions 23b is offset by about half of the predetermined interval on the left and right passage walls. Yes. The plurality of protrusions 23b are also provided to reduce the pressure caused by the weight of the game ball located on the upstream side so that the pressure is not excessively increased on the downstream side.

  As described above, in a standby state in which the game ball introduced into the ball feeding member 60 through the receiving passage 56 is received in the receiving portion 63, the game ball wins a winning tool (not shown) of the game board 10. Then, the ball payout control board (not shown) outputs a command signal for rotating the ball payout motor 65 by a rotation angle corresponding to the winning condition (a rotation angle corresponding to the number of prize balls to be paid out). 8 rotates the ball payout motor 65 based on the command signal to rotate the ball feed member 60 counterclockwise in FIG.

  When the ball feeding member 60 rotates, the game ball received in the receiving portion 63 is pushed downstream by the receiving wall 62 and sent out to the payout passage 57 and is introduced into the next receiving portion 63 from the receiving passage 56. A game ball is received. The game balls sent out to the payout passage 57 flow down the payout passage 57 and are paid out from the payout outlet 53 to the ball payout passage 25a. It is paid out to the dish (see FIG. 14).

  At this time, the game ball sent out to the payout passage 57 with the rotation of the ball feed member 60 is sent out to the payout passage 57 at a speed corresponding to the rotation speed of the ball feed member 60. Therefore, when the rotational speed of the ball feeding member 60 is high, the delivered game ball is a passage wall (for example, A shown in FIG. 8) on the opposite side (the side shown in FIG. 8) of the payout passage 57 to the ball feeding member 60. However, in the ball dispensing device 50, such a game ball can be obtained by providing the guide rib 58. This prevents the ball from bouncing off (game ball rampage) and allows the game ball to flow smoothly.

  Thereafter, similarly, the game balls held on standby in the receiving passage 56 are received one by one in the receiving portion 63 of the ball feeding member 60 as the ball feeding member 60 rotates, and as the receiving portion 63 rotates, Are sent out to the payout passage 57, flow down the payout passage 57, and discharged from the payout outlet 57 to the ball tray of the ball tray unit 6 through the ball discharge passage 25a. Then, the ball feeding member 60 is rotated by a rotation angle corresponding to a command signal to the ball payout motor 65, whereby a number of game balls according to winning conditions are paid out to the ball tray of the ball tray unit 6 as prize balls. .

  In addition, when a ball lending operation is performed in a so-called CR machine and the operation signal is input to the pachinko machine PM, the ball payout is performed in the same manner as when the game ball is won in the winning device of the game board 10 described above. A game ball payout operation is performed by the device 50.

  The rotation angle of the ball payout motor 65 included in the command signal is a rotation angle corresponding to the number of game balls to be paid out, and when the rotation operation of the ball payout motor 65 is stopped, any of the receiving parts 63. Is set so as to receive the game ball introduced from the receiving passage 56 and restrict the flow of the game ball.

  The game balls flowing down the payout passage 57 are detected by a ball detection sensor 75, and the detection signal of the ball detection sensor 75 is output to a ball payout control board (not shown), and the ball payout control is performed. The board counts the actual number of game balls paid out from the detection signal, and feedback-controls the operation of the ball payout device 50 based on the counted value. Thereby, an accurate quantity of game balls are paid out as prize balls or rental balls, and a fair game can be provided.

  In addition, when the operation member 72 of the ball removing mechanism 70 is operated and slid to the upper position in a state where the game ball is held on standby in the receiving passage 56 as shown in FIG. 8, as shown in FIG. The passage wall member 71 is swung counterclockwise in FIG. 15 by the pressure of the game ball located on the upstream side, and changes to a position where the notch portion 56 c of the receiving passage 56 is opened. Then, the game ball that has passed through the notch 56c flows down the ball removal passage 59 and is discharged from the ball discharge port 54 to the discharge passage 25b provided in the back set board 20, and flows down the discharge passage 25b to play the game island. It is discharged to the recovery device (see FIG. 13).

  Here, in the ball dispensing device 50, the guide passage 55 and the dispensing outlet 53 are provided on the front side, and the ball removal passage 59 and the ball removal port 54 are provided on the rear side when attached to the back set panel 20. ing. Therefore, for example, even if the operation member 72 of the ball removal mechanism 70 is slid and moved to the upper position, and the illegal operation is added to the mounting state of the ball dispensing device 50 to the back set board 20, it passes through the notch 56c. Thus, the game balls discharged from the ball discharge passage 59 and the ball discharge port 54 are discharged to the back of the pachinko machine PM and discharged to the ball tray of the ball tray unit 6 through the ball payout passage 25a. However, it is possible to prevent the game ball from being illegally acquired by such an unauthorized operation.

  As described above, according to the ball dispensing device 50 according to the present embodiment, the guide passage 55 is arranged in the lower bent portion 56b of the receiving passage 56 so that the direction in which the game ball is introduced into the ball feeding member 60 is Since it is formed obliquely with respect to the vertical direction along the rotational tangential direction, the pressure based on the weight of the game ball acting on the ball feeding member 60 and the like is reduced. For this reason, it is possible to reduce the starting torque at the time of starting the rotation that requires the largest rotational torque, and thus it is possible to use a motor that is smaller than the conventional one and to reduce the size of the apparatus.
