Description of the Related Art Generally, in a slot machine, a front door is attached to a front opening of a housing, and a start switch, three stop switches, a reel display window, etc. are provided on the front door, and at the same time, in the housing. Three reels, each of which has a plurality of symbols drawn on the outer peripheral surface, are displayed through the reel display window.
When the reels are arranged in a horizontal row so that the symbols can be seen, all reels rotate when the player operates the start switch for each game, and when all reels stop by sequentially operating the three stop switches. The presence or absence of a prize is determined by whether or not a predetermined combination of symbols is aligned on the reel display window.

In a computer-controlled slot machine of recent years, in order to make this combination of winning symbols appear evenly, the rotation of the reel is started by the operation of the start switch and at the same time an internal lottery is carried out, and the lottery is carried out. In the case of winning, even if the operation timing of the stop switch operated by the player is slightly deviated, if it is within the allowable range, so-called pull-in control for controlling the reel stop position so that the symbol of the winning combination appears Done. In particular, when a bonus game such as a big bonus is won in the internal lottery, a bonus flag is set and the pull-in control is repeated for each game until the player aligns the bonus symbols on the reel display window.

In this type of slot machine, when the bonus flag is established and the bonus symbol appears, a so-called flag notification is made to inform the player of the game situation in an easy-to-understand manner.

In FIG. 8, first, after waiting for the operation of the start switch 16 which is the operation for starting the game in step S1, the winning lottery is carried out in step S2 and the production mode lottery is carried out in step S3. The prize lottery decides whether or not to win a big bonus, regular bonus, a small role, etc., and the production mode lottery decides whether or not there is a production and the production mode when there is a production. Done by. In the production mode, the display contents of the production display device 30, that is, four types of dolls 35a to 3a
5d is to be displayed, and the opening degree of the pair of shutter members 41, 41 of the shutter device 40 is to be one of four stages of full open, large, medium, and small. In the case of the present embodiment, four types of dolls 35a to 35
d is selected corresponding to the winning combination of the winning lottery, for example, the doll 35a is a big bonus, the doll 35b is a regular bonus, and the doll 35c is a big bonus or a regular bonus. Occasionally, the doll 35d is selected at the time of lottery loss including winning of a role other than the big bonus or the regular bonus. Further, since the opening of the shutter members 41, 41 is fully opened for a while, the dolls 35a to 35 of the display contents are displayed.
If the size of the dolls 35a to 35d is large, the size of the dolls 35a to 35d can be roughly recognized. The state in which the type of puppet cannot be recognized is only for a moment when the small person opens the doll 35 for about 1/8 to 1/10.
Representing a state where it is difficult to recognize the types of a to 35d, the lottery probabilities are set high in the order of small>middle>large> fully opened, and particularly small and medium lottery probabilities are set considerably high.

Subsequently, it is determined in step S4 whether or not the big bonus or the regular bonus is won. If the determination is YES, the bonus winning flag F is set to 1 in step S5. In step S6, it is determined whether or not another winning combination is won. If the determination is YES,
In step S7, the winning flags of other winning combinations are set to 1. NO in step S4 or step S6
In the case of, the flag is left as it is and the process proceeds to the next step.

In step S8, a game is executed. In the execution of this game, first, in step S21, the three rotary reels 25a to 25c of the reel device 24 are rotationally started in accordance with the subroutine shown in FIG. Subsequently, in step S22, it is determined whether or not the result of the effect mode lottery previously performed is effect. If the result of the determination is YES, the effect display device 3 corresponding to the effect mode in step S23.

In step S24, the player waits for the push operation of the stop switches 17a to 17c to be performed, and then in step S25, the rotary reel 25a corresponding to the stop switches 17a to 17c.
Stop ~ 25c. Then, in step S26, it is determined whether or not all three rotating reels 25a to 25c of the reel device 24 have stopped, and if the determination is NO, step S26.
On the other hand, if the determination is YES, the process returns to step S24.
At 27, based on the signal from the reel initial position detector 56, it is determined whether or not the winning symbols are aligned on the winning lines L1 to L5 of the reel display window 8.

After executing such a game, the process returns to the flow shown in FIG. 8 and it is determined in step S9 whether or not a bonus prize is won. When this determination is YES, the bonus flag F is returned to 0 in step S10, the bonus game process is executed in step S11, the winning flags of other combinations are returned to 0 in step S12, and the process returns. On the other hand, when the determination in step S9 is NO, it is determined in step S13 whether or not there is another winning combination, and when the determination is YES, the other winning combination process is executed in step S14, and then the process proceeds to step S12. However, if the determination is NO, the process directly proceeds to step S12.

Next, in order to explain the contents of the effect performed in step S23, first, the player operates the start switch 16 to operate the three rotating reels 25a-2a of the reel device 24.
When 5c is rotated, at the same time as the rotation, the shutter members 41, 41 of the shutter device 40 open to the fully open state, and the turntable 33 of the production display device 30 rotates, and four types of dolls on the turntable 33 are rotated. 35a
˜35d is rotated and displayed to the player side through the upper panel 4 inside the frame portion 1a which is a see-through window.
