When the game ball enters the special area 15, the open state of the variable winning port 10 is based on the entrance detection signal from the detection switch 14a (functioning as a character continuously operating device) existing in the special area 15. Is further continued for a predetermined time.

The above description shows the operation of the main game mechanism in the case of performing the first type game by the embodiment of the pachinko machine of the present invention, and the first type other than the above-mentioned mechanisms. The control of the operation of each game mechanism generally found in conventional pachinko machines (for example, the opening time control for ending the opening of the special winning opening and the winning number control, etc.) is the same as that of the conventional pachinko machines of the present invention. This is similar to the case of the type 1 pachinko machine.

Next, an operation mode of the above-mentioned variable winning device 2 on the game board 1 and each mechanism shown in Table 1 when the player or the game hall provider selects the second type game with the game selection switch 77. Will be described below.

The game ball launched in the game area on the game board 1 enters the special game guide winning opening 6 (in this case, it functions as a two-kind starting opening) installed in the variable winning device 2,
When detected by the winning detection switch 7, both movable wing pieces 9 of the variable winning device 2 are activated and the variable winning opening 10 (which functions as a big winning opening at this time) is opened and closed twice at intervals of about 0.5 seconds. Repeatedly, the second solenoid 25 has a predetermined cycle (for example, ON for about 0.3 seconds, OFF for about 0.7 seconds).
Second) keeps the ON / OFF repeated state for about 5 seconds. In addition, in this game content, the stop chamber 20 remains in the ineffective state (that is, the first solenoid 24 is O
Continue the FF state). FIG. 10 is a time chart clearly showing the operation timing of each mechanism at the start of the special game situation based on the entry of the game ball into the special game guide winning opening 6 when the second type game is executed.

Next, a part of the game ball entered from the variable winning a prize opening 10 during the repeated opening and closing reaches the game ball guiding passageway 17 from the shelf plate 12 through the stop chamber 20 and turns on the second solenoid 25. The obstacle member 29 which repeatedly rises and falls on the shelf plate 12 in conjunction with the ON / OFF repeating state.
It is possible to pass or jump over a with a certain probability to enter the special area 15 (in this case, it functions as a V zone). Then, when the game ball enters the special area 15, the detection switch 14a existing in the special area 15
Based on the detection signal from (functions as a continuous accessory operating device), the opening and closing of the variable winning port 10 is continued a predetermined number of times.

The above description shows the operation of the main game mechanism when the second type game is performed by one embodiment of the pachinko machine of the present invention. Type Pachinko machine Control of operation of each game mechanism generally found in conventional products (for example, opening and closing time control for finishing continuous opening and closing of the special winning opening and winning number control)
The same applies to the pachinko machine of the present invention as in the case of the conventional type 2 pachinko machine. When the second type game is selected, the variable display device 3 displays the number of open / close rounds of the variable winning a prize mouth 10 and the decorative pattern in the big hit situation.

Next, the operation mode of the above-mentioned variable winning device 2 on the game board 1 and each mechanism shown in Table 1 when the player or the game hall provider selects the third type game with the game selection switch 77 Will be described below.

The game ball shot in the game area on the game board 1 enters the special game induction winning opening 6 (which functions as a normal symbol working opening in this case) installed in the variable winning device 2 and wins the prize. When detected by the detection switch 7 (which normally functions as a symbol display switch in this case), one type of hit on the screen (in this case, it functions as a normal symbol display body) installed in the variable display device 3 1 consisting of a design (not shown) and 9 types of out-of-design (not shown)
The 0 kinds of normal symbols are variably displayed at a predetermined switching speed (for example, about 0.032 seconds per symbol), and after a certain period of time (for example, 3 seconds), the symbols are stopped and displayed specifically. At this time, when the symbol specifically displayed on the screen 3a becomes the above-mentioned winning symbol, both the variable winning a prize device 2 are movable based on the drive control condition of each device according to the symbol data signal when the symbol hit is established. The wing piece 9 operates and the variable winning opening 10
(Functioning as a specific area at this time) is opened for about 5 seconds, and the second solenoid 25 is turned on at a predetermined cycle (for example, ON for about 0.4 seconds and OFF for about 0.6 seconds).
Keep the N / OFF repeat state for about 7 seconds. In addition,
At this time, the stop chamber 20 remains in the ineffective state (that is, the first solenoid 24 continues to be in the OFF state).

Therefore, a part of the game ball entered from the open variable winning opening 10 reaches the game ball guiding passage 17 from the shelf 12 through the stop chamber 20 and the second solenoid 25.
In accordance with the ON / OFF repeated state, the obstacle member 29a that repeatedly rises and descends on the shelf plate 12 passes or jumps with a certain probability, and the special area 15
(In this case, it functions as a special device operating area). When the game ball enters the special area 15, the so-called special profit game right is generated based on the entrance detection signal from the detection switch 14a existing in the special area 15.

On the other hand, the first solenoid 24 is shifted to the ON state based on the ball detection signal, and the ball stopping member 2
When 1 advances to the front of the game board 1, the stop chamber 20 becomes effective (that is, the state where the game ball can be stopped). As a result, the special area 1 of the subsequent game ball entered from the variable winning port 10 after the special profit game right is generated
5 can be prevented from entering. This valid state continues until the ON / OFF repeated state of the second solenoid 25 is completed.
