In FIG. 10, the wire 55 is exaggeratedly drawn so as to largely protrude upward from the gap portion between the discharge opening end forming portion 50 and the ball opening end 37a. 55 is in contact with the bottom of the back frame 13b while projecting upward from the gap by a predetermined gap sp, and cannot move upward any further.

  As shown in FIG. 1, the pachinko machine PM having the above configuration is used for a game in a state where the front frame 2, the glass door 5, and the ball tray 6 are all closed and locked. Then, when the player stores the game ball in the ball tray 6 and rotates the operation handle 8, the pachinko game (ball game) is started. That is, when the operation handle 8 is rotated in the clockwise direction in FIG. 1, the game balls stored in the ball tray 6 are launched one by one into the game area PA of the game board 10 by a ball striking device (not shown). Since then, the ball game has been developed.

  When a game ball launched into the game area PA wins a start winning device (not shown) at the position of the opening 17, a special symbol lottery (the first jackpot is won) by a lottery function of the main control board included in the control unit 30. As a result, a special symbol and a decorative symbol are variably displayed for a predetermined time on an image display device (not shown) at the position of the opening 15. In this special symbol lottery, based on the random number value acquired when winning the start winning device, the first big win and the second big winning device 14 for opening and closing the lid 19a of the first big winning device 19 by a predetermined number of rounds. A second jackpot that opens and closes the opening / closing member 35 by a predetermined number of rounds, and a disengagement that does not become one of the first and second jackpots are determined. On the display unit of the image display device, a decoration pattern corresponding to the special symbol corresponding to the determination result of the special symbol lottery is displayed, and a display mode (for example, “777”, “555” that finally matches the three symbols is displayed. ”“ 333 ”), and finally, a display mode in which the three symbols do not match (for example,“ 527 ”“ 346 ”), etc. are displayed.

  When the game ball is introduced to the stage S from the discharge port 24 through the warp introduction port 16 of the center ornament 13, the game ball rolls to the left and right so as to temporarily stop on the stage S, and finally Specifically, it falls below the stage S and wins a start winning opening, or flows down to the game area PA without being awarded to the starting winning opening and is taken into the lower out opening 23.

  When the first jackpot is won, the lid 19a of the first big winning device 19 as the lower attacker is opened a predetermined number of times. That is, when the lid body 19a is opened for a predetermined time, or when, for example, nine or more game balls are won, the lid body 19a is once closed and closed by a predetermined number of times (for example, 15 times) repeated continuously. During this time, the game ball Ba launched into the game area PA by the operation of the operation handle 8 by the player is received by the opened lid body 19a, thereby corresponding to each game ball won in the first grand prize winning device 19 respectively. Then, a large amount of game balls (prize balls) to be paid out are released onto the ball tray 6.

  On the other hand, when the second jackpot is won, the opening / closing member 35 of the second big winning device 14 as the upper attacker is different in stages (for example, three stages (16 times, 32 times, 48 times)). Opened. In other words, the game ball Ba launched into the game area PA is received and won at the upper part of the game area PA by the opening / closing member 35 that is opened in small increments every predetermined time. In this way, a large amount of game balls (prize balls) to be paid out in correspondence with each game ball won in the second grand prize winning device 14 is discharged onto the ball tray 6. The game ball Ba that has won the second grand prize winning device 14 when the opening / closing member 35 is opened is introduced into the opening (not shown) from the game ball introduction path 26 and detected by the detection sensor, and then the discharge path 36 is passed through. As a result, the game board 10 is discharged to the back side of the game board 10 via the first discharge path 38 and the second discharge path 37.

  As described above, in the present embodiment, the ball discharge path that discharges the game ball Ba that has won the second grand prize-winning device 14 to the back side of the game board 10 is provided in the center decoration 13 integrally with the first discharge path 38. And the game ball Ba from the first discharge passage 38 is received and discharged with the ball opening end 37a facing the discharge opening end 46 of the first discharge passage 38. And a discharge passage 37. Then, by attaching the center decoration 13 having the first discharge passage 38 and the second discharge passage 37 to the back of the game board 10, the ball discharge passage can be easily formed by the first discharge passage 38 and the second discharge passage 37. Can do. In this way, the ball discharge path can be formed regardless of which of the center decoration 13 and the second discharge passage 37 (ball discharge unit 33) as separate parts is attached to the back of the game board first.

  In the present embodiment, the ball discharge path can be divided into a first discharge path 38 on the center decoration 13 side and a second discharge path 37 on the back side of the game board. The order of the assembly process of the center decoration 13 having the second discharge passage 37 can be eliminated. Therefore, during assembly, maintenance, inspection, etc., whichever of the first discharge passage 38 and the second discharge passage 37 on the center decoration 13 side is attached to the back of the game board first, the standard state Can be assembled. For example, when it is desired to remove only the second discharge passage 37 (ball discharge unit 33) for maintenance or the like, it is not necessary to remove the first discharge passage 38 (back side frame 13b), or vice versa. When it is desired to remove only the (back side frame 13b), it is not necessary to remove the second discharge passage 37 (the ball discharge unit 33), and the workability is greatly simplified. As described above, the first discharge passage 38 and the second discharge passage 37 on the side of the center decoration 13 do not overlap each other, and both can be assembled and disassembled in an arbitrary order, so that the work is performed very efficiently. And the workability can be greatly improved.

  Further, in the present embodiment, since the predetermined gap sp is provided between the first discharge passage 38 and the second discharge passage 37, even if the foreign matter is clogged in the ball discharge passage (38, 37). Even if the foreign matter is smaller than the gap sp, the foreign matter can be easily removed from the gap sp. Further, for example, by inserting a predetermined tool (not shown) through the gap sp, the inner wall surfaces of the first discharge passage 38 and the second discharge passage 37 can be cleaned. Furthermore, it is possible to very easily check the quality of the flow situation of the game ball Ba between the first discharge passage 38 and the second discharge passage 37. For example, after a thin sheet-like inspection tool is inserted and the game ball from the first discharge passage 38 is temporarily stopped, the inspection tool is pulled out and dropped to the second discharge passage 37 side to determine the flow state of the game ball. As a result, it is possible to easily and reliably check the quality of the flow paths in the first discharge passage 38 and the second discharge passage 37. At this time, if the game ball does not flow smoothly, it can be determined that there is a problem such as a narrow flow path. These operations can be performed very easily and efficiently with the first discharge passage 38 and the second discharge passage 37 attached to the back of the game board 10.

  In the present embodiment, the first discharge passage 38 is disposed in the space between the front side frame 13a and the back side frame 13b, and the discharge opening end 46 is provided in the opening 39 provided at the bottom of the back side frame 13b. A predetermined gap sp is disposed between the opening 39 at the bottom of the back frame 13b and the entrance opening end 37a of the second discharge passage 37. For this reason, the opening part of the bottom part of the back side frame 13b can be obtained by simply attaching the back side frame 13b of the center decoration 13 and the ball discharge unit 33 having the second discharge passage 37 to the back of the game board in a predetermined order. 39 and the inner opening wall surfaces of the first discharge passage 38 and the second discharge passage 37 as described above by making sure the positions of the inlet opening end 37a of the second discharge passage 37 are aligned with each other and using a predetermined gap sp. In this state, it is possible to easily perform cleaning and removal of foreign matter in the passage.

  In this embodiment, since the opening area of the ball opening end 37a of the second discharge passage 37 is formed larger than the opening area of the discharge opening end 46 of the first discharge passage 38, even a malicious player If the wire 55 or the like is inserted from the discharge opening end 37b side of the second discharge passage 37 and enters the first discharge passage 38 side to try fraud, the first discharge passage 38 and the second discharge passage 37 Since there is a complicated structure in which there is a predetermined gap sp at the connecting portion and the opening area of the discharge opening end 46 of the first discharge passage 38 is small, the wire 55 or the like enters the first discharge passage 38 side. It becomes a very difficult situation. As a result, fraud can be prevented with a very high probability.
