Then, if there is a winning combination corresponding to the random number value, the CPU 200 wins the lottery result by using the winning combination as the winning combination of the game, and stores the winning combination in the internal lottery flag 204 of the storage unit 201. Here, the lottery method of winning combination is called “internal lottery”.

  Next, an outline of the game operation in the slot machine 1 will be described. The slot machine 1 enters a standby state when a prize is won in a previous game and a medal payout is completed, or when a loss is confirmed in the previous game. In this standby state, a standby mode effect is provided that suggests the state to the player and prompts a game operation. Next, when the player inserts a medal into the medal insertion unit 71 or presses any one of the bet buttons 72, 73, 74, the slot machine 1 can receive the corresponding medal (credit) from the inside. A game is prepared by betting a predetermined number of medals on the game.

  When the start lever 75 is tilted and the game is started in the game preparation state, the main control board 20 starts to rotate the three reels 101a, 101b, and 101c all at once and executes the internal lottery described above. The result of the internal lottery is stored in the internal lottery flag 204.

  Next, when one of the stop buttons 76a, 76b, and 76c is pressed by the player, the reels 101a, 101b, and 101c are stopped, and the main control board 20 displays the symbols displayed on the stopped reels and the above-described symbols. It is determined whether or not the symbol combination related to the winning combination corresponding to the internal lottery flag 204 matches.

  When the combination of these symbols matches the winning combination of the internal lottery and the winning combination is confirmed, the slot machine 1 controls the medal credit means 210 by the main control board 20, and the number of credits of the medal stored internally is determined. Until a predetermined number is reached, medals with a predetermined number of payouts are added to the number of credits according to the type of the combination. Further, when the addition result of the number of payouts and the number of credits exceeds the predetermined number, the slot machine 1 pays out the surplus number of medals to the tray unit 6a.

  In this state, the liquid crystal display panel 305 controls the sub-control board 30 (see FIG. 3) to transmit the diffused light from the liquid crystal shutter 304 by controlling the transmittance of each pixel, thereby allowing the liquid crystal display panel 305 to pass through the front surface. A standby image, an image related to the progress or production of the game, and the like are displayed. Thereby, the player sees the standby image displayed on the liquid crystal display panel 305 through the display window 48a from the outside of the slot machine 1 (see FIG. 1), the image related to the progress and production of the game, and the like. .

  Next, when the game proceeds to a specific state such as winning a specific small role, confirming a big win, shifting to a high-probability lottery state, or the like in the game progress state, the sub-control board 30 (see FIG. 3) displays a liquid crystal shutter. The illumination light R1 incident on the rear surface 304 is controlled so as to be transmitted and guided forward as indicated by the solid line, and all the pixels of the liquid crystal display panel 305 are controlled to the maximum transmittance.

  In this state, the liquid crystal display panel 305 and the liquid crystal shutter 304 are almost transparent, and the shape of the effect member 302 can be recognized from the front side of the liquid crystal display panel 305. In this state, the sub-control board 30 (see FIG. 3) drives the drive unit 321 and swings the arms 324a and 324b of the effect member 302 up and down. Thereby, the player visually recognizes the effect member 302 from the outside of the slot machine 1 (see FIG. 1) via the display window 48a, and confirms that the transition to the specific state is felt with high impact.

  According to the liquid crystal display effect device 48 having such a configuration, the liquid crystal shutter 304 and the liquid crystal display panel 305 are opposed to each other through the gap 307 by the spacer members 373 a and 373 b interposed between the liquid crystal shutter 304 and the liquid crystal display panel 305. Since the liquid crystal shutter 304 and the liquid crystal display panel 305 do not enclose bubbles or foreign matter or cause adhesion spots, the liquid crystal display panel 305 is not generated without causing moire interference fringes. A uniform state can be maintained.

  The present invention can be applied not only to slot machines but also to other gaming machines such as pachinko machines that display images.
