And insert into the shaft (50).

  A small motor (52) is attached to the rear surface of the mounting frame (30), and a pinion (53) attached to the rotating shaft (52a) of the motor (52) meshes with the gear portion (36), so that the motor Due to the rotation of (52), the turntable (28) is driven to rotate counterclockwise in FIG. A ring-shaped light emitting diode (54) serving as a light emission source is attached to the back of the mounting frame (30).

  As shown in FIG. 2, the special symbol display device (14) is attached behind the panel (55) in the game area (13). A decorative frame (57) is attached to the inner periphery of the display window (56) of the panel. The range of the opening window (57a) of the decorative frame (57) is the central part of the rotating disk (28), and includes the water surface (45a) of the liquid (45), the surrounding fins (41), and the partition protrusions (43 ) And the auxiliary fin (41) are obscured. A stage (60) is provided under the opening window (57a) of the decorative frame.

Next, the operation will be described.
When the motor (52) rotates, the rotating disk (28) rotates counterclockwise (arrow A direction) in FIG. 4 via the pinion (53) and the gear portion (36). As a result, the fin (41) is moved downward while the opening (42) side of the fin (41) enters the liquid (45) from the air layer (46) and the air is contained in the fin (41). Go to. When the opening (42) of the fin (41) is directly downward, the air is kept in the fin (41), but the position where the opening (42) is slightly lateral (P1), Air is gradually released at (P2), and is largely released at the positions (P3) and (P4) where the opening (42) is gradually upward.

  Due to the release of air, the bubbles (58) rise in the liquid (45). At this time, the auxiliary fins (44) and the partition projections (43) collide with the bubbles (58) coming out of the fins (41), and the bubbles (58) are finely crushed to form fine bubbles. In addition, since the intervals between the auxiliary fins (44) are irregular, it is possible to scatter the bubbles (58) with a natural feeling by making the air discharge position in the fins (41) irregular, and more directing The effect can be enhanced. The bubbles (58) generated in the rotating disk (28) are illuminated by the light emitting diode (54) behind and become more interesting. As described above, the liquid level (45a), the fin (41), the auxiliary fin (44), and the part of the partition projection (43) are covered with the decorative frame (57). Only 58) will be visible.

  The liquid (45) and the rotating disk (28) are not limited to being colorless and transparent as long as they are light transmissive. For example, when the symbols (6a), (6b), and (6c) of the liquid crystal display device (25) are viewed through the liquid (45) and the rotating disk (28), the symbols (6a), (6b), (6c) In order to make the liquid (45) or the rotating disk (28) resemble the sea as long as the visibility of () does not deteriorate, it is also possible to give a color such as blue.

  Each symbol (6a) (6b) (6c) displayed in the “reach state” and displayed on the special symbol display device (14) has a predetermined display mode, and there is a high possibility that a big hit will occur. In this case, the rotating disk (28) is rotated to generate bubbles in the internal liquid (45). If the possibility of a big hit is small, the last one symbol is displayed. When the confirmation is displayed, the turntable (28) is not rotated.

  “Reach” means that two symbols out of the three symbols (6a), (6b), (6c) (see FIG. 1) that are variably displayed on the special symbol display device (14) are the same symbol. A final display is performed, and the remaining one changing symbol is displayed with the same symbol as the two stop symbols, thereby indicating a state where a big hit may occur.

  By acting as described above, the symbols (6a), (6b) and (6c) displayed on the special symbol display device (14) are displayed through the liquid (45) in which bubbles (58) are generated. As a result, it is possible to produce a three-dimensional effect, and the player can play the game while viewing the symbols (6a), (6b), and (6c) with a high level of expectation. Figured.

  As mentioned above, although embodiment of this invention was described, in the range which does not deviate from the summary of this invention, it is possible to give a various deformation | transformation and change to the said embodiment.

  For example, it is possible to color the bubble generation screen by using a light emitting diode having a desired light emitting color. It is also possible to change the bubble generation by changing the rotation speed of the rotating disk (28).

  Furthermore, a small piece (59) (shown in FIG. 4) having a specific gravity greater than that of the liquid (45) is enclosed in the accommodation space (40) of the rotating disk (28) together with the liquid (45). The small piece (59) sinking to the bottom of the plate is taken into the fin (41) as the turntable (28) rotates, and the fin (41) into which the small piece (59) is taken reaches near the top. Thus, the small piece (59) may fall from the fin (41) and sink into the liquid (45). By doing in this way, the production effect can be further enhanced together with the generation of bubbles (58). Moreover, you may give various colors and shapes to the small piece (59).
