Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine such as a pachinko machine, an arrange ball machine, and a play ball game machine.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, one or a plurality of symbols on a symbol display device fluctuates for a predetermined time and stops on condition that a starting device detects a game ball. When the later stop symbol is a predetermined specific symbol (a so-called big hit symbol), a profit state is generated by the profit state generating means, and the variable winning means has a first state advantageous to the player and a second state disadvantageous to the player. There is one that performs the conversion operation.

The variable winning means constitutes a so-called big winning means. When the stop symbol of the symbol display means is a big hit symbol, the opening / closing plate pivots forward around the horizontal axis to open the winning port. A game ball that is opened and falls from above along the game board is guided to a winning opening by an opening / closing plate.
The winning area of the variable winning means is determined by the left and right widths of the opening and closing plate, and is usually constant in the range of 55 mm to 90 mm.

[0004]

The variable prize means usually closes the opening / closing plate when a predetermined time elapses after the opening or when 10 game balls have been won, and when the game balls won during the opening are in a specific area. The opening / closing operation is repeated up to a predetermined number of times, for example, up to 16 times, on condition that the vehicle passes. Therefore, if the profit state is generated by the profit state generating means, the player can receive a great return of profit by opening and closing the variable winning means.

However, in the conventional ball game machine, the prize area of the variable prize means is constant and does not change during the game, so that the player can obtain a substantially constant profit by generating a profit state. There is a problem that is poor and lacks interest.

SUMMARY OF THE INVENTION [0006] In view of the above-mentioned conventional problems, it is an object of the present invention to provide a ball-and-ball game machine in which a game state after a profit state is generated can be changed and the player's interest can be improved.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a variable winning means 13 which can be converted into a first state which is advantageous to a player and a second state which is disadvantageous to the player, a starting means 12, and the starting means 12 comprises a game. A symbol display means 18 for displaying one or more symbols that fluctuate and stop for a predetermined time on condition that a ball is detected, and a stop symbol after the symbol display means 18 fluctuates is a predetermined specific symbol. Sometimes, in the ball game machine provided with the profit state generating means 65 for generating the profit state by converting the variable winning means 13 to the first state, a winning area in the first state of the variable winning means 13 Is provided with a prize area changing means 25 for changing the prize area.

12 selects the random number on condition that the game ball is detected. In addition, the second random number selecting means 62 is, for example, 0 to 249 when the big hit occurrence probability that the stop symbol of the second symbol display means 18 becomes a big hit symbol is 1/250.
The random number for determining the jackpot / out-of-position is generated.

Reference numeral 63 denotes a second symbol display control means, provided that a game ball wins in the second starting means 12, on the basis of the random number for determining the jackpot / missing selected by the second random number selection means 62, and the variation pattern determining means. It has a function of changing each game symbol of the second symbol display means 18 for a predetermined time and stopping it according to a random number, a random number for determining a stop symbol, and the like. For example, when the second random number selection means 62 selects a jackpot random number value. After the variation pattern determined by the variation pattern determining random number, the game symbol is stopped at a combination of specific symbols determined by the symbol random number, for example, a stop symbol such as "7 / 7.7".

Numeral 64 is a storage means for storing a predetermined number (for example, four) of winnings when a game ball is won in the second starting means 12 while the game symbol of the second symbol display means 18 is changing; Each time the change operation of the second symbol display means 18 is completed, the game symbols of the second symbol display means 18 are changed in accordance with the stored number.

Numeral 65 is a profit state generating means. The second random number selecting means 62 selects a big hit random number value, and it is variable when the changed game symbol of the second symbol display means 18 is a big hit which is a combination of specific symbols. The winning means 13 is converted from the second state to the first state to generate a specific profit state advantageous to the player.

That is, the profit state generating means 65 is provided after the change of the jackpot / out-of-range random numbers drawn by the second random number selecting means 62 and / or the second symbol display means 18 when the game ball is awarded to the second starting means 12. Is determined from the stop symbol of the game, and when the stop symbol of the game symbol after the change of the second symbol display means 18 becomes a jackpot symbol such as “7.7.7”, the variable winning means 13 The open / close plates 22 to 24 are opened to generate a profit state advantageous to the player.

The profit state generating means 65 is a second symbol display means.
The jackpot determination unit 73 for determining whether a big hit or a miss from the stopped symbol after the change of 18 and generating a profit state advantageous to the player, and the stopped symbol after the change of the second symbol display means 18 is a big hit. In addition to the opening / closing control unit 66 that controls the opening and closing of the open / close plates 22 to 24 of the variable winning means 13 when a symbol is formed, the winning area of the variable winning means 13 is stepwisely changed in a plurality of stages according to the type of the big hit symbol. It has a prize area control section 67 for controlling the change, and a prize area display control section 68 for controlling the display of the prize area display means 57.

In the winning area control section 67, the winning area of the variable winning means 13 is set according to the type of the big hit symbol, and when the stopped symbol after the change displays the big hit symbol of a predetermined type, the variable. A control signal is sent to the opening / closing control unit 66 so as to change the winning area of the winning means 13 according to the type of the big hit symbol.

For example, the prize area control unit 67 sets “0.0
Of the 10 types of jackpot designs from "0" to "9/9/9",
In the case of "3.3.3" and "7.7.7", the driving means 36 to 38 of the prize area changing means 25 are operated and the prize area is wide area.

According to the type of the big hit symbol, the driving means 36 and 38 operate at the time of 9.9 to become the middle area A2, and the driving means 36 operate at the time of other even-numbered symbols to become the narrow area A3. The area control signal is transmitted to the opening / closing controller 66.

The prize area display control section 68 sets "0.0.0"
-Of the 10 types of jackpot designs of "9/9/9", "3
In the case of "3.3" and "7.7.7", the display lamps 58 corresponding to the open / close plates 22 to 24 are changed to "1.1.1", "5.5.
The display lamps 58 corresponding to the main opening / closing plate 22 and the sub opening / closing plate 24 at the time of “5” and “9 ・ 9 ・ 9”, and the display lamps 58 corresponding to the main opening / closing plate 22 at the time of other symbols blink. It is made to let.

Note that the profit state generating means 65 includes
The opening / closing operation is continued up to a predetermined number of times (for example, up to 16 times) on condition that the game ball that has won a prize while the 24 is open passes through the specific area 27.

Next, the operation of the above-mentioned ball game machine will be described. The game ball fired on the upper side of the game board 3 is the first
After passing through the starting means 14, the first random number selecting means 59 selects a random number at that time, the first symbol display control means 60 performs random number judgment and other processing according to the random number, and the first symbol displaying means 19 The symbol is changed for a predetermined time.

If the random number value selected by the first random number selecting means 59 is a hit random value, the game symbol of the first symbol display means 19 stops at the hit symbol, and the opening / closing control means 61 operates to activate the second starting means 12. The pair of open / close claws 12a are opened. For this reason, a game ball is easily won in the second starting means 12, and accordingly, a game symbol of the second symbol display means 18 is easily changed.

When a game ball wins in the second starting means 12, the second random number selecting means 62 selects a random number value at that time, and the second symbol display control means 63 determines whether or not the random number value is a jackpot random number value by random number processing. Then, the game symbols displayed on the second symbol display means 18 are varied in a predetermined variation pattern for a predetermined time so as to stop at a predetermined stop symbol according to the determination result.

After the change, the three stop symbols are "7.7.7"
When a specific symbol such as a jackpot symbol is displayed, the profit status generating means 65 operates to generate a profit status in which all or a part of the open / close plates 22 to 24 of the variable winning means 13 is opened to the front side. For this reason, many of the game balls falling from the upper side of the game board 3 easily enter the variable winning means 13 through the open / close plates 22 to 24, so that once a big hit occurs on the second symbol display means 18 side, A great profit will be returned to the player.

At this time, the prize area control section 67 operates according to the type of the stop symbol after the change of the second symbol display means 18, and outputs an area control signal for determining the open / close plates 22 to 24 to be opened of the variable prize means 13. It is transmitted to the opening / closing controller 66. Therefore, even when the profit state is generated by the profit state generating means 65, the winning area changes in three stages depending on the type of the big hit symbol, and the game balls falling along the game board 3 are changed into the variable winning means 13.
The winning efficiency when winning is changed.

That is, when the stop symbol after the change is a combination of even symbols among the ten types of jackpot symbols "0.0.0" to "9.9.9", the solenoid of the central main drive means 36 40, the central main opening / closing plate 22 is rotated about the horizontal axis 34 to be in an open state, so that the winning area of the variable winning means 13 becomes a narrow area A3, and the main opening / closing plate 22 wins a game ball. Guide to mouth 21. For this reason, the variable winning means 13 keeps the open state until a predetermined time elapses after opening of the main opening / closing plate 22 or until one game ball wins.
Only the game ball falling on 22 wins the winning opening 21, and the winning efficiency when the game ball wins the winning opening 21 is lower than in other cases.

However, the stop symbol after the change is "1.1.
1 "," 5.5.5 "or" 9.9.9 "
The solenoids 40 and 46 of the two driving means 36 and 38 are energized to
Each of the open / close plates 22 and 24 rotates around the horizontal axis 34 to be in an open state, and the winning area of the variable winning means 13 becomes the middle area A2. For this reason, the game ball is guided to the winning opening 21 by the two opening / closing plates 22 and 24, so that the game ball wins the winning opening 21 in comparison with the narrow area A3 where only the main opening / closing plate 22 is open. Efficiency is improved.

In the case of "3.3.3" or "7.7.7", the solenoids 40, 45, 46 of the three driving means 36 to 38 are provided.
And the three opening / closing plates 22 to 24 are rotated about the horizontal axis 34 to be in an open state.
It becomes A1, and the game ball is guided to the winning opening 21 by the three opening / closing plates 22 to 24. For this reason, the game ball can efficiently enter the winning opening 21 as compared with the case where the main opening / closing plate 22 or the main opening / closing plate 22 and one of the sub opening / closing plates 24 are opened.

The game ball that has won the winning opening 21 is in the specific area 27.
Alternatively, the game ball is guided to the back side of the game board 3 through the winning paths 28 and 29, and the game ball is detected by the counting switch 33. And
When the counting switch 33 detects ten game balls, or when a predetermined time has elapsed after the opening and closing of the open / close plates 22 to 24, the power to the solenoids 40, 45, and 46 is cut off by the open / close control unit 66 to open and close. Plates 22-24 close. When the game ball passes through the specific area 27, the opening / closing operation is repeated up to 16 times on condition that the specific area detection switch 32 detects the game ball.

As described above, even in the case of the same jackpot, the winning area of the variable winning means 13 changes stepwise in a plurality of steps depending on the type of the stop symbol after the change, and thus the type of the stop symbol after the change is a game. There is an advantage that it becomes a matter of concern for the player and can be varied and enhance the interest of the player.

When the winning area of the variable winning means 13 changes, the display lamp 58 corresponding to each of the open / close plates 22 to 24 in the wide area A1, the main open / close plate 22 and the auxiliary open / close plate 24 in the middle area A2.
The main opening / closing plate when the display lamp 58 corresponding to
The display lamps 58 corresponding to 22 flash and emit light, respectively, to display the change of the winning area to the player. For this reason, the player can easily grasp the change in the winning area by the blinking light emission of the display lamp 58.

FIG. 9 illustrates a second embodiment of the present invention,
Two sub-opening / closing plates 23 and 24 are arranged on one side of the main opening / closing plate 22. When the winning area is changed by one main opening / closing plate 22 and two sub opening / closing plates 23, 24, the arrangement of the opening / closing plates 22 to 24 can be variously changed. Of course, 2
Any one of the sub-opening / closing plates 23 and 24 may be combined with the main opening / closing plate 22.

In addition, the number of the open / close plates may be four or more, and the width of the right / left plates may be the same. In short, the prize area changing means 25 only needs to have a structure in which the prize area changes stepwise by changing the number of the open / close plates 22 to 24 that open and close. However, when any one of the opening / closing plates 22 to 24 is opened, it is desirable to provide a possibility that the game ball will win the specific area 27.

FIG. 10 illustrates a third embodiment of the present invention, in which two opening / closing plates 22, 23 having the same width or substantially the same width are connected to a winning opening.
It is arranged on the left and right of 21. In this case, it can be similarly implemented. However, also in this case, the specific area 27 is disposed substantially at the center in the left-right direction, and when one of the two opening / closing plates 22 and 23 is opened, the game ball wins in the specific area 27. It is desirable that the possibility arises.

FIG. 11 exemplifies a fourth embodiment of the present invention.
