BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a front view of a pachinko machine 1, in which a ball tray and a rotary handle for shooting balls are provided at a lower portion (not shown) of the machine frame 2. In the center of the board of the game board 3,
As shown in an enlarged manner in FIG. 2, a center case 4 is provided, and symbol display portions 7a, 7b, 7c and a winning number display portion 8 are provided in a circular window hole 5 formed in the center of the center case 4.
Are arranged in a cross at equal angular intervals of 90 °, and the symbol combination display 6 is supported rotatably on the back of the circular window hole 5 with the rotating shaft 10 at the back thereof. Has been established. At the center of the symbol combination display 6, a standby recording lamp array 11 including four pilot lamps is provided. The seven segments are constituted by LEDs or liquid crystals.

The symbol combination display 6 has a rotating shaft 1
0 is meshed with a driven gear 12a concentrically fixed to the rear of the drive motor 12b, which is fixed to the drive shaft of the reversible drive motor M, so that the reversible drive motor M can rotate left and right by 180 degrees. As shown in FIG. 2, the central symbol display section 7c is at the top position. The angle control can be easily performed by using a stepping motor for the reversible drive motor M. At this time, when the power is turned on, a positioning plate 13 having a positioning slit formed on the rotating shaft 10 so that the symbol combination display 6 is at an appropriate position.
(See FIG. 3), the slits are detected by sensors s, s, and a normal position (see FIG. 4A) and an inverted position rotated by 180 ° (see FIG. 4B) are detected. Stop control of the reversible drive motor M is performed. In addition, as the angle control means, a positioning means such as providing a stopper at the 180 ° position for engaging with the rotating shaft 10 on the back surface of the circular window hole 5 or the like or applying the driven gear 12a to only the 180 ° It can be easily achieved by means such as forming with a toothless gear having teeth.

The symbol display sections 7a, 7b, 7c are:
Symbols such as “0” to “9”, “A”, “J”, “L”, etc., which can be expressed by a 7-segment indicator composed of numbers and alphabets are displayed. The winning number display section 8 indicates “0” to
“9” is displayed on the 7-segment indicator, and the number of winnings in the special winning opening 23 is counted as described later.

A winning opening 1 is provided above the center case 4.
8 are provided. A single 7 is located immediately below the winning opening 18.
A single symbol display device 19, which is a segment indicator and displays numbers from "0" to "8", is provided.

On both sides of the center case 4, starting gates 20, 20 provided with ball detecting devices (not shown) constituted by photoelectric switches, limit switches, and the like are provided. When a ball detection signal is generated by the detection device, the single symbol display device 19 starts to be driven and fluctuates in nine symbols “0” to “8”.

Further, a starting port 14 is also provided immediately below the combination display device 6, and a winning opening opening / closing device 15 is disposed immediately below the starting port 14. This winning opening opening and closing device 15
Is a closed position in which only the falling of the game ball from directly above is effective in the upright state of the pair of opening and closing wings 16 and 16, and the inside of the game ball when the pair of opening and closing wings 16 and 16 are tilted in an inverted octagon. Is controlled to be converted to an open position for guiding the motor through an electric drive means. The starting port 14 or the winning port opening and closing device 1
When a ball flows into 5, the combination display device 6 starts driving, and the symbol display portions 7a, 7b, 7c fluctuate.

Below the winning opening / closing device 15, a winning device 22 having a wide special winning opening 23 is provided. The prize winning device 22 opens the cover 24 in the front-rear direction by using a solenoid, so that the cover 24
The guiding action of the present invention has a known configuration for guiding game balls to the special winning opening 23. When a game ball enters the specific area as described later with the central portion of the special winning opening 23 as a specific area, a continuous opening operation is performed. Is caused.

The operation of the above configuration will be described. When the game ball is launched and flows into the starting openings 13, 13, the single symbol display device 19 starts to drive, and “0” to “8”
Fluctuate in 9 symbols. After about 8 seconds, the fluctuation stops, and when the symbol is an "odd number", the winning opening opening / closing device 15 is in the open state, and the opening / closing wing piece pair 16, 16 is tilted. This opening operation is an intermittent opening operation, for example, opening about 1.4 seconds for about 15 seconds four times. It should be noted that a single opening that closes with the inflow of the ball may be used. As a result, the game balls easily flow into the starting port 14, and the operation frequency of the combination display device 6 described below is improved.

Next, when the game ball passes through the starting port 14 or the open winning opening opening / closing device 15, the combination display device 6 is driven together with the supply of the prize ball. In the case of continuous passage, the standby recording lamp array 11 is sequentially turned on and held up to four times.

When the combination display device 6 is driven,
The symbol display units 7a, 7b, 7c start to fluctuate, and after about 8 seconds elapse, the fluctuation of the symbol display units 7a, 7b, 7c stops in this order. At this time, as shown in FIG. 4A, when the symbols on the symbol display section 7a and the symbol display section 7b coincide with each other, the symbol combination display 6 is rotated by 180 ° while the fluctuation state of the symbol display section 7c is maintained. The symbol display section 7c is moved to the reverse position, and the symbol display section 7c is moved to the lowermost position, and the fluctuation speed of the symbol display section 7c is reduced.
Expectations of "big hit" where b and 7c are all the same design are enhanced. When the symbol display section 7c stops at a different symbol, the symbol combination display 6 rotates 180 ° counterclockwise and returns to the original position.

On the other hand, the symbol display portions 7a, 7b, 7c are, for example, "1,1,1", "2,2,2", "3,3".
In the case where symbols such as "3,""4, 4, 4" and "A, A, A" are the same, the symbol combination display 6 maintains the reversal position while the "big hit" is displayed. The notification device emits a sound and the winning device 2
The solenoid 2 is driven, the lid 24 is tilted forward, and the special winning opening 23 is opened. The special winning opening 23 is continuously driven when passing through the specific area, and is opened again after the opening operation is completed. After this opening operation is completed, the symbol combination display 6 returns to the normal position,
Further, as the vehicle passes through the specific area, the motor rotates half a turn to the reverse position. The number of times of the continuous operation is up to 16 times, and the opening operation is temporarily ended when ten game balls are won in the special winning opening 23 or when a predetermined time has elapsed. The number of up to ten game balls passed through the special winning opening 23 is counted in the winning number display section 8.

In this way, the symbol combination display 6
When "reach" and "big hit" are caused by the rotation of, this is dynamically expressed, and a dynamic play mode is produced.

Also, "2,2, X", "4,4, X",
A combination of "6, 6, X" (X is a variable) or the like may be used as a small hit in which the special winning opening 23 is opened for a short time and a small number of times.

Further, the symbols are "3,3,3",
In the case of a specific symbol such as “7, 7, 7”, the probability that the single symbol display device 19 will be an odd number for opening the winning symbol opening / closing device 15 after the opening operation of the special winning port 23 is completed. Becomes 10 times. For this reason, the opening frequency of the winning opening / closing device 15 is dramatically increased, and accordingly, the operation frequency of the combination display device 6 is improved, and the probability of a big hit again increases. This probability is maintained until the next big hit occurs. Alternatively, it may be maintained until the combination display device 6 fluctuates a predetermined number of times.

The above-described series of operations can be easily executed by control command means including a central control unit CPU and the like.

[0021]

As described above, according to the present invention, the symbol combination display 6 is constituted by disposing the symbol display portions 7a, 7b, 7c around the center of rotation at equal angular intervals of 90 °. The symbol combination display 6 is rotatably supported by a reversible drive motor M in a window hole 5 formed in the game board, and is reversible when the symbol design of the symbol display portions 7a, 7b, 7c is a predetermined combination. By driving the drive motor M and turning the symbol combination display 6 half a turn from the normal position to the reverse position, a mechanical change is caused to promote the player's feeling of excitement. There is an excellent effect that can create a play style with a lively feeling.
