In the embodiment shown in the drawings, in order to suspend the operation of the shutter mechanism, a screw 220 is provided behind the ball stopping member 213 as an operation suspending member so that the screw 220 can be retracted. Since the shutter mechanism is necessary when the game board 38 for playing a general game is attached, the tip of the screw 220 is separated from the rear end of the ball stopping member 213. By doing so, when there is insufficient balls in the prize ball tank and the engagement / disengagement operating portion 219 descends, the ball stopping member 213 descends sufficiently and the ball stopping piece 212 stops the ball.

On the other hand, when the special prize mode is established, the game board is configured to be converted into a particularly advantageous state for the player for a certain period of time,
For example, when the hitting ball enters the special winning opening 103, the conversion display device 106 performs high speed conversion display of numbers, and when this conversion display is stopped, special prize modes such as “7”, “7”, and “7” are available. In the case where the game board 38 in which the conversion winning device 105 opens the door and converts the ball into a state in which it is easy to accept the hit ball for a fixed time is attached, as shown in FIG. 32, sufficiently tighten the screw 220. Every time, even if the balls in the prize ball tank are insufficient and the engagement / disengagement operating portion 219 descends, the screw 220 locks at the rear end of the ball stopping member 213 to prevent the descending, and the ball stopping member 213 does not act. To do so. By doing so, even if the conversion winning device 105 is in a state where it is easy to receive the balls, even if the number of balls in the prize ball tank is insufficient, the player can shoot the balls, and there is no disadvantage. The operation stop member is not limited to the screw 220, and may have any configuration as long as the operation of the ball stop member 213 can be stopped.

<Effects of the Invention> As described above, according to the present invention, the game board locking member may be preassembled as a single unit and then mounted on the frame.
