  Up to this point, the configuration of the pachinko machine PM (game body device 10) has been described. Hereinafter, the operation of the signboard drive device 60, which is a characteristic configuration of the present invention, will be described with reference to FIG. FIG. 10 is a front view of the game main body device 10 and shows a state where the decorative signboard 61 is moved to the lower position A, the middle position B, and the upper position C by the signboard driving device 60.

  In the following description, the decorative signboard 61 located at the upper position C at the start of the pachinko game moves to the lower position A after moving to the middle position B according to the transition of the gaming state, and further from the lower position A to the middle. The case where it moves to the upper position C after moving to the position B is illustrated. When the pachinko game is actually developed, there are various movement patterns of the decorative signboard 61 according to the transition of the gaming state.

  At the start of the pachinko game, for example, the locking balls 63a and 66a are supported by the ball support devices 70R and 70L, respectively, and the decorative sign 61 is located at the upper position C, and this state is detected and detected by the position detection sensor 68c. The result is output to the control device. In the upper position C, the upper part of the decorative signboard 61 is in a state of entering the back side of the game board 40. However, since the game board 40 is formed using a transparent material as described above, the player Can visually recognize the entire decorative signboard 61 including the upper part of the decorative signboard 61.

  In the middle of the development of the pachinko game, when the game ball that has been struck enters a predetermined game state, for example by winning the start winning device 43, the control device sends an operation signal to the electromagnets 72, 74. Output and generate magnetic force for a moment. Due to this magnetic force, the support blocks 71 and 73 are attracted to the electromagnets 72 and 74 for a moment (see FIG. 8B), and then immediately return to the original state (see FIG. 8A). In a moment when the support blocks 71 and 73 are attracted to the electromagnets 72 and 74, the decorative signboard 61 falls due to its own weight. Then, the locking balls 63b and 66b are supported by the support blocks 71 and 73 that have come into contact with each other, and the decorative signboard 61 is in the middle position B. By being positioned at the middle position B, for example, it can serve as a shutter that hides part of the effect image displayed on the liquid crystal display panel 80, and a visual effect can be provided to the player. Moreover, by dropping the decorative signboard 61 by its own weight, it is possible to produce a movement with impact, and it is possible to enhance the entertainment and fully enjoy the game.

  In the above state, when the pachinko game continues to be developed and the game ball further enters the start winning device 43 and shifts to a predetermined game state, the control device outputs an operation signal to the electromagnets 72 and 74 again. , Generate magnetic force for a moment. Similarly to the above, the decorative signboard 61 is dropped by its own weight, the locking balls 63c and 66c are supported by the support blocks 71 and 73, and the decorative signboard 61 is in the lower position A. In the lower position A, the lower end portion of the decorative signboard 61 is positioned in the vicinity of the movable winning device 44, but does not interfere with the game ball passage provided on the back side of the movable winning device 44. . Moreover, in the lower position A, most of the decorative signboard 61 is in a state of entering the back side of the game board 40, but the game board 40 is formed using a transparent material as described above. The player can visually recognize the entire decorative signboard 61. In this way, by further dropping the decorative signboard 61 from the middle position B to the lower position A, it is possible to enhance the interest while giving the player a sense of expectation for further winning through vision. .

  If the pachinko game is continuously developed and the decorative signboard 61 is shifted to the predetermined play state with the decorative signboard 61 positioned at the lower position A, the decorative signboard 61 is raised from the lower position A to the middle position B, for example. The operation of the signboard driving device 60 at this time will be described. In a state where the support blocks 71 and 73 are attracted to the electromagnets 72 and 74 that are energized, the drive motor 62 is driven, and the winding portions 64a and 67c are connected to the wires 63 and 63. 66 is gradually wound up. As described above, since the gear 67 and the gear 64 have the same shape, both end portions of the decorative signboard 61 can be raised synchronously, and the decorative signboard 61 can be prevented from being inclined obliquely during the ascent. It is like that.

  Then, the fact that the decorative signboard 61 is located at the middle position B is detected by the position detection sensor 68b, and the detection result is output to the control device, whereby the control device stops the drive of the drive motor 62 and the electromagnet. The power supply to 72 and 74 is cut off. By doing so, the locking balls 63b and 66b are supported by the ball support devices 70R and 70L, respectively, and the decorative signboard 61 can be positioned at the middle position B. Further, when the pachinko game is developed and the decorative signboard 61 is in the middle position B and the state is shifted to a predetermined game state, the decorative signboard 61 is raised from the middle position B to the upper position C in the same manner as described above.

  As described above, in the pachinko machine PM according to the first embodiment, the decorative signboard 61 is moved over a wide range beyond the visual opening 45 (display area of the liquid crystal display panel 80) formed in the game board 40, and the movement is performed. Since the player can visually recognize the decorated signboard 61 that has been made through the transparent game board 40, it is possible to produce an effect that enhances interest through vision. In addition, for example, while performing illumination by LED illumination from the left and right ends of the decorative signboard 61 toward the decorative signboard 61, and changing the color of the electric decoration according to the vertical position of the decorative signboard 61, it is more effective. Production through vision is possible.
