[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of converting a first state, which is difficult to accept a ball and is disadvantageous to a player, to a second state, which is easy to accept a ball and is advantageous to the player, when a specific condition is satisfied. The present invention relates to a variable winning device for a pachinko machine.

[0002]

2. Description of the Related Art There have been proposed a number of variable prize winning apparatuses for converting a state that is unfavorable to a player into a state that is advantageous to the player when a specific condition is satisfied. For example, a armor portion is provided above the special winning opening as an obstacle member for blocking the inflow of the ball, and the game portion in which the ball flows down below the armor portion is rotatable to define the special winning opening. When a specific condition is established such that a wing piece is provided and a ball is won at the starting winning opening, the drive source is driven to rotate the wing piece so that the winning opening and the gaming section are in communication with each other. There is one that takes in the ball flowing down the game department into the winning opening by the wing pieces that have moved. In addition, when the front of the special winning opening is covered with a rotatable gate and certain conditions are met,
There is one in which the gate is rotated by the drive of a drive source so that the ball flowing down the game section is taken into the special winning opening.
Further, according to Japanese Examined Patent Publication No. 63-6229, when two winning openings are opened by providing a step at the top and bottom, and wing pieces that can be opened and closed are provided at these winning openings, and a ball wins a specific winning area, A winning device is known in which the winglets are opened.

[0003]

However, in the conventional winning apparatus, even if the movable members such as the winglets and the gate are converted into the second state, the movable members are located below the obstacle members such as the armor. positioned. Therefore, in the conventional prize winning device, the area in which the movable member can win the prize can be expanded in the horizontal direction, but cannot be expanded in the vertical direction. Therefore, in the conventional winning device, if the ball flowing down the game portion collides with the obstacle member even during the conversion to the second state,
Since this ball has been pushed out of the winning area and the obstacle member is still operating, the ball flowing down the gaming section cannot be reliably taken into the special winning opening. In other words, the player cannot fully enjoy the profit in the second state and remains dissatisfied.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above-mentioned points, and an obstacle member and a movable member which define a game section and a special winning opening are provided around the special winning opening and are specified. When the above condition is satisfied, the movable member is moved by the drive source so that the first state in which the player develops unfavorably can be changed to the second state in which the player develops in an advantageous manner. The movable member is
Composed of a pair of members and located on the left and right of the obstacle
And, on the end of the movable member, as the case of the first state is positioned below the upper surface portion of the obstruction member, and,
In the second state, it is set to be located above the upper surface portion of the obstacle member.

[0005]

[Operation] It consists of a pair of left and right members, and the left side of the obstacle member.

Next, a game of the pachinko machine 1 having the above-described variable winning device 12 and variable display device 10 will be briefly described.

When the power is turned on, a CPU (not shown)
The electric control device of the configuration performs initial settings such as clearing of the built-in RAM and checking of each part, and if there is no abnormality, each symbol display device displays a $ mark.

Then, when the ball hit by the player flows into any of the starting ports 11 provided in the game section 5'and a starting port switch (not shown) provided in the starting port 11 is turned on, In response to a command from the electric control device, each symbol display device starts variable display and stops after a certain period of time. That is, the left symbol display device cyclically displays the $ mark and the numbers 1 to 9 as the display symbols at a predetermined movement time, and the middle symbol display device displays the $ mark and the numbers 1 to 9 and F, H, J as the display symbols. ,
The letters P and O are cyclically displayed for a predetermined movement time, and the right symbol display device is a $ mark and the numbers 1 to 9 and F, H, J, and
The P character is cyclically displayed at a predetermined moving time. In addition, hereinafter, the above-mentioned $ mark, number and character are simply referred to as a design.

When the starting opening switch is turned on, the electric control device performs a big hit determination process. The big hit determination process includes a first big hit determination random number sequence (0 to 14), a second big hit determination random number sequence (0 to 14), and a hit numerical value selection random number sequence (0
~ 5), the random number sequence for winning symbols (0 to 9), 1 in the above order
The addition process is repeated one by one, and the values of the random number sequence for selecting a hit number at the time when the sphere flows into the starting port 11 ... Are stored, and the predetermined numbers of the random number sequence for determining the first big hit corresponding to the stored values are stored. It is a hit value. Then, the numerical value of the second big hit determination random number sequence at the time when the ball flows into the starting port 11 ... And the first big hit determination at the time when a predetermined time (for example, 5 seconds) has elapsed from the start of the symbol variation display Based on the numerical value of the random number sequence for use, "big hit" or "out" is determined. It is possible to store a maximum of four prizes in the starting opening 11, and the numerical value of the second big hit determination random number sequence at the time when there is a winning to be stored is stored. Do not remember the numerical value. Therefore, the hit value of the random number sequence for determining the first big hit does not change. When four winning memories are further won in the starting port 11 ..., the oldest memories are erased and updated to the numerical value of the second jackpot determining random number sequence at the time when there is a new winning.

Then, when the numerical value of the first big hit determination random number sequence and the numerical value of the second big hit determination random number sequence are predetermined numerical values, it is determined as "big hit". For example, when the winning number selection random number sequence at the time of winning the starting opening 11a is "0", the first jackpot determination random number sequence is "0", and the second jackpot determination random number sequence is The case of "0" is defined as "big hit". And, regardless of the numerical value of the random number sequence for selecting the winning numerical value, "big hit"
The probability is set to be about 1/200. still,
The stop symbol of each symbol display device is determined based on the numerical value of the random number sequence for winning symbols when a predetermined time has elapsed since the symbol display device started the variable display, and for example, the numerical value of the random number sequence for winning symbols is " At the time of "0", each symbol display device displays a $ mark and stops.

When the numerical values of the first big hit determination random number sequence and the second big hit determination random number sequence are other than a predetermined combination, "out"
Becomes However, when only the first big hit determination random number sequence has a hit value, the left symbol display device and the middle symbol display device stop at the same symbol. In this case, the stop symbol of the left symbol display device and the middle symbol display device is determined by the numerical value of the random number sequence for the winning symbol at the time when a predetermined time has passed since the symbol started the variable display, and the first symbol at the same point The right symbol display device stops at the corresponding symbol in the right symbol pattern table based on the numerical value of the random number sequence for deviation symbol (0 to 12).

Also, if the numerical value of the first big hit determination random number sequence is not a predetermined value, the second out-of-design symbol random number group at the time when a predetermined time has elapsed since the symbol started variable display, that is, the left symbol For second off symbol random number sequence (0-9), second off symbol random number sequence for medium symbols (0-14), second off symbol random number sequence for right symbol (0-14) each symbol display in the corresponding symbol The device stops. The combination of "big hit" and the combination of the left design and the middle design are excluded.

As described above, each symbol display device is stopped, and after about 1 second, a winning combination is determined based on the stopped symbols, and when the symbols displayed by each symbol display device are complete,
That is, in the case of "big hit", the special winning opening 17 is opened.
The special winning opening 17 is opened by driving the drive motor 35, and the movable member 20 is raised by the drive mechanism.
The winglet 27 rotates to open the continuous winning opening 25. This open state continues for about 18.5 seconds, but when a predetermined time elapses or when 10 balls are won in the special winning opening 17, the drive motor 35 is rotated again and the crank pin 45 is moved from the upper moving cam 46.
The movable member 20 suddenly returns and slides to close the special winning opening 17. And, during the opening, the continuous winning hole 2
When the sphere flows into 5 and the continuation switch 26 is turned on, after the opening operation is completed, the opening operation of the movable member 20 is restarted,
The opening operation can be repeated up to 10 times.

Further, by disposing the upper edge piece 28 of the movable member 20 having an inclination and the appropriately arranged obstacle nails N ... In the movable member 20 movable state, the left and right movable members 20.
It is also possible to guide a ball flowing down from a position outside the winning area between the two to another winning port. For example, in the case of the game board 5 arranged as shown in FIG. 12, the movable member 20 can be guided to the left and right starting ports 11b and 11c at the raised position.

13 to 14 are time charts showing the relationship between the starting port, the symbol display device, and the movable member (large winning hole).

Although the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the above-mentioned embodiments and can be appropriately implemented without changing the configuration described in the claims. For example, although the obstacle member is configured to be openable and closable in the embodiment, the obstacle member may be formed of a fixed member like an armor and a continuous winning opening may be provided in the special winning opening.
