Description

  The present invention relates to a ball game machine, and more particularly to a game ball collection structure.

As is well known, in a pachinko game that is a typical example of a ball game, pachinko balls used as game balls in various winning holes provided in the game area of the game board surface equipped in the pachinko game machine are used. When winning a prize, a predetermined number of prize balls set in the winning opening are paid out.
Some pachinko machines have a symbol change display device using a liquid crystal panel or the like at the center of the game board, and it is now possible to change and display symbols such as lottery status and lottery results according to winnings. Yes.

A display device that displays the symbol is provided with a decorative member surrounding the periphery, and some of the decorative members are provided with a blinking lamp or a moving character according to the contents of the effect. Further, there is a display provided with a liquid crystal panel in addition to the symbol variation display device (for example, Patent Document 1).
On the surface of the game board, the pachinko balls launched toward the game area flow down from the upper side of the decorative member to the side, and in the process, it enters the role or becomes the out ball as it is, In recent years, there is a tendency for the display device to occupy the game board surface because the display contents in the display device using the liquid crystal panel are diversified.

For this reason, since the space which the decoration member arrange | positioned around the display apparatus occupies also becomes large, it has become difficult to ensure the space for a pachinko ball to flow down by the side of a decoration member.
Accordingly, in view of the current situation on the game board surface, a configuration has been proposed in which a ball passage directed from the upper side of the decorative member to the side is provided in the decorative member, and the end of the ball passage is positioned on the back side of the decorative member. (For example, Patent Document 2).

On the other hand, pachinko balls launched on the game board surface of the pachinko machine enter the game outlets that are paid out as prize balls in the process of flowing down the game board surface, or the out-ball collection out port provided at the bottom of the game board. .
The pachinko balls that have entered the winning opening are guided to the prize ball discharging device by the guide passage, and are detected as winning balls one by one and then discharged out of the machine through the prize ball discharging passage. When a winning ball is detected, a predetermined number of pachinko balls are paid out from the winning ball payout device based on this signal. Pachinko balls that have entered the out port are discharged out of the machine through the out ball guide passage. (For example, patent document 3).

As mentioned above, if the pachinko ball's flow-down space on the game board becomes smaller, the probability of winning the big prize opening located at the bottom of the game board will decrease because the flow direction of the pachinko ball is more likely to be restricted. There is a risk of doing.
Therefore, as a configuration for preventing such a decrease in the winning probability, it is conceivable to provide a large winning opening in the upper part of the decorative member in the game board, that is, the upper part of the game board.
JP 2004-57655 A (paragraph “0032” column) Japanese Patent Laying-Open No. 2005-21490 (paragraph “0013” column) JP-A-8-19645 (paragraph "0002" column)

However, when the big winning opening is provided in the upper part of the game board, the configuration for collecting the winning balls may be complicated. Normally, pachinko balls discharged from a gaming machine are collected by a ball collecting mechanism provided on the island facility side where the gaming machine is installed in a state of communication with a ball discharging unit of the gaming machine.

When a game ball wins the start winning opening 6c, it passes through the start winning opening sensor 6cs. Thereby, the detection signal at that time is transmitted to the winning ball detecting means 21 from the start winning hole sensor 6cs. When receiving this detection signal, the winning ball detecting means 21 detects that a game ball has won the start winning port 6c.

  Similarly, the special winning opening sensor 6ds is a sensor that is provided at a predetermined position of the special winning opening 6d and constantly monitors the winning of a game ball to the special winning opening 6d. When a game ball wins the special winning opening 6d, it passes through the special winning opening sensor 6ds. Accordingly, the detection signal at that time is transmitted from the special winning opening sensor 6ds to the winning ball detecting means 21. When receiving this detection signal, the winning ball detecting means 21 detects that a game ball has won the special winning opening 6d. When this detection signal is received, the winning ball detection means 21 operates as if a game ball has won the special winning opening 6d, and is performed by the lottery means 22 described later, which triggers the start of the lottery.

(Lottery means)
The lottery means 22 performs a lottery regarding the stop symbol displayed on the symbol variation display device 6j which is a variable display means, on condition that the winning ball detecting means 21 detects the winning of the game ball to the start winning opening 6c. In this embodiment, “1” winning / non-winning presence, “2” symbol variation display device 6 j after symbol variation display, and “3” symbol variation display during variation display. Make a lottery. The lottery means 22 includes a winning lottery means 22a, a stop symbol lottery means 22b, and a variation pattern lottery means 22c in order to perform the lottery of “1” to “3”.

(Winning lottery means)
In this embodiment, the winning lottery means 22a includes a winning determination random number generating means, a winning determination random number acquiring means, and a winning determination means.
The hit determination random number generating means generates a hit determination random number having a predetermined cycle (for example, a cycle of 0 to 65535 by a 16-bit random number) by a control program or the like. The hit determination random number obtaining means detects one hit determination random number among the hit determination random numbers generated by the hit determination random number generation means, at a predetermined time, in the present embodiment, a detection signal transmitted from the start winning opening sensor 6cs. Is acquired when the winning ball detecting means 21 receives the.

The winning determination means determines whether the winning is determined or not based on the winning determination random number acquired by the winning determination random number acquiring means. Of the random numbers for hit determination of a predetermined period generated by the random number generator for hit determination, a random number corresponding to winning is determined in advance. Then, when the winning determination random number acquired by the winning lottery random number acquisition means matches the random number corresponding to winning, it is determined to be winning, and when it does not match, it is determined not to win.
Here, in this embodiment, when the gaming state is a normal gaming state or a time shortening gaming state described later, the winning probability is set to 1/327.
On the other hand, in the probability variation gaming state described later, the winning probability is set to 1/51.

(Stop symbol lottery means)
The stop symbol lottery means 22b draws a stop symbol to be stopped and displayed on the symbol variation display device 6j based on the determination result of the hit determination means of the hit lottery means 22a. Here, if the winning determination means of the winning lottery means 22a determines that the winning is made, any one winning symbol is selected by lottery from a plurality of winning symbols.
The stop symbol lottery means 22b is used when the winning determination means of the winning lottery means 22a determines that the winning symbol is selected. The winning symbol selection random number generation means, the winning symbol selection random number acquisition means, and the winning symbol selection means. With.

  The winning symbol selecting random number generating means generates a winning symbol selecting random number having a predetermined period by a control program or the like. Then, the winning symbol selection random number acquisition means acquires one winning symbol selection random number among the winning symbol selection random numbers generated by the winning symbol selection random number generation means. Next, the winning symbol selecting means selects a winning symbol corresponding to the winning symbol selecting random number acquired by the winning symbol selecting random number acquiring means.

  In the present embodiment, the stop symbol as identification information to be stopped and displayed on the screen of the liquid crystal display device 6a corresponding to the display unit is composed of three symbols (numerals) of left, middle and right. It has 1000 ways to “999”. Then, a combination of three predetermined symbols is set as a winning symbol (for example, “777”, “331”, “531”, etc.). In the present embodiment, the stop symbol lottery means 22b has the same three symbols, "000", "111", "222", when the winning determination means of the winning lottery means 22a determines that the winning symbol is won.・ ・ Select one of the 10 winning symbols up to “999”. The design which is such identification information is not limited to characters represented by numerals, but may be symbols, figures, or a combination thereof.

In this embodiment, the ten winning symbols from “000”, “111”, “222”,... “999” are all selected with the same probability. That is, the selection probability of each winning symbol is set to 1/10. As a result, the probability that an odd symbol (“111”, “333”, etc.) is selected as the winning symbol and the probability that an even symbol (“000”, “222”, etc.) is selected are both ½. Become.
Here, in the pachinko gaming machine 100 according to the present embodiment, three types of gaming states are provided: a normal gaming state, a probability variation gaming state, and a time shortening gaming state.

The “probability game state” is a game after the special game is ended when the symbol stopped and displayed by the liquid crystal display device 6a becomes an odd symbol (eg, “111”) of the winning symbols. A gaming state that is set until the next special game is started and has a winning probability higher than the normal gaming state and the time-reduced gaming state (as described above, a gaming state having a winning probability of 1/51 ).

In addition, the “time-reduced gaming state” means that when the symbol stopped and displayed by the liquid crystal display device 6a in the probability variation gaming state becomes an even symbol (for example, “222”) among the winning symbols. In the game after the game ends, it means a game state set only for a predetermined number of games (for example, 100 games). Then, when the predetermined number of games is performed in the time-reduced game state, the time-reduced game state is terminated and the normal game state is entered.
Here, in the probability variation gaming state and the time reduction gaming state, the time from the start of symbol variation to the stop display by the liquid crystal display device 6a is set to be shorter than the normal gaming state.

  When the symbol stopped and displayed by the liquid crystal display device 6a in the normal gaming state or the time-saving gaming state becomes an even symbol (for example, “222”) of the winning symbols, the special game is ended. The subsequent game is in a normal gaming state. As described above, the normal gaming state and the time reduction gaming state are gaming states having a winning probability of 1/327.

In addition, the stop symbol lottery means 22b is used when the winning determination means of the winning lottery means 22a is determined not to win, the non-winning symbol selection random number generating means, and the non-winning symbol selection random number acquiring means; And a non-winning symbol selection means.
The non-winning symbol selection random number generating means generates a non-winning symbol selection random number having a predetermined cycle by a control program or the like. Then, the non-winning symbol selection random number acquisition means acquires one non-winning symbol selection random number among the non-winning symbol selection random numbers generated by the non-winning symbol selection random number generation means. Next, the non-winning symbol selecting means selects a non-winning symbol corresponding to the non-winning symbol selecting random number acquired by the non-winning symbol selecting random number acquiring means.

In the present embodiment, if it is determined that the winning symbol is not selected, the random number is independently acquired for each of the left symbol, the middle symbol, and the right symbol by the random symbol generating means for selecting the non-selected symbol, and the acquired random number. The left symbol, middle symbol, and right symbol are selected based on the above.
Here, the stop symbol lottery means 22b is “000” out of 1000 stop symbols from “000” to “999” when the hit determination means of the hit lottery means 22a determines that the winning symbol is not won. A non-winning symbol is selected so that ten winning symbols “111”,.

(Variation pattern lottery means)
The variation pattern lottery means 22c is for drawing a variation pattern of symbols to be displayed on the liquid crystal display device 6a.
The fluctuation pattern lottery means 22c includes a fluctuation pattern selection random number generation means, a fluctuation pattern selection random number acquisition means, and a fluctuation pattern selection means.
The variation pattern selection random number generation means generates a variation pattern selection random number having a predetermined period by a control program or the like. Then, the variation pattern selection random number acquisition unit acquires one variation pattern selection random number among the variation pattern selection random numbers generated by the variation pattern selection random number generation unit. Next, the variation pattern selection means stores the variation patterns of a plurality of types of symbols based on the variation pattern selection random number acquired by the variation pattern selection random number acquisition means and the determination result by the hit determination means of the winning lottery means 22a. One variation pattern is selected with reference to the data table.

  In this embodiment, two data tables (for variation pattern selection) for winning and non-winning are provided, and when the winning determination means determines that the winning is made, the data table for winning is selected. The variation pattern corresponding to the obtained variation pattern selection random number is selected. Similarly, when it is determined that the winning determination means does not win, a variation pattern corresponding to the acquired random number for variation pattern selection is selected using the data table for non-winning.

Here, in this example, at the start of the variable display of the symbols, after all the three symbols are displayed in a variable manner, the left symbol, the right symbol, and the middle symbol are stopped and displayed in this order, and finally all the three symbols are displayed. To stop display.
At this time, when the left symbol and the right symbol are the same among the three symbols, control is performed so as to display the reach state. Here, the reach state means a state in which the left symbol and the right symbol are the same when the left symbol and the right symbol are stopped and the middle symbol is still in the variable display.

  For example, when the selected stop symbol is a winning symbol such as “333” or “777”, or the left and right symbols are the same but the middle symbol is the same as “313” or “787”. If not, the left and right symbols are stopped and displayed, and the middle symbol is variably displayed to indicate the reach state. Then, when such a stop symbol is selected, a variation pattern for displaying the reach state is selected. In this variation pattern, a plurality of variation patterns having different reliability, which are finally stopped and displayed with the winning symbol, are provided in advance. For example, it is possible to provide a variation pattern 1 having a low probability of being stopped and displayed on the winning symbol and a variation pattern 2 having a high probability of being stopped and displayed on the winning symbol.

In this case, when the winning symbol is selected by the stop symbol lottery unit 22b, the variation pattern lottery unit 22c selects the variation pattern 2 with a higher probability than the variation pattern 1.
On the other hand, when the non-winning symbol is selected by the stop symbol lottery means 22b, the variation pattern lottery means 22c selects the variation pattern 1 with a higher probability than the variation pattern 2.

(Design display control means)

The symbol display control means 23 controls the change display and stop display of symbols based on the lottery result of the lottery means 22. That is, the symbol display control means 23 performs control so as to perform symbol change display and stop display according to the stop symbol selected by the stop symbol lottery means 22b and the variation pattern selected by the variation pattern lottery means 22c.

(Special game control means)
In the special game control means 24, the winning determination random number acquired by the winning determination random number acquiring means of the winning lottery means 22a matches the winning random number, and the symbol stopped and displayed by the symbol variation display device 6j is the winning symbol (for example, "777"), the game is shifted to a special game, and the special game is executed until the end condition is satisfied. Here, “special game” means that a state in which a game ball is more likely to win than a normal game is created. Specifically, the special game port 6d is opened and a game ball can be easily received. This is a game that can be expected to win prize balls.

During the special game, the special game control means 24 controls the driving of the special prize port driving device 6dd for opening and closing the special prize port 6d.
The special game control means 24 controls the driving of the special prize opening driving device 6dd to open the special prize opening 6d, and performs the opening time of the special prize opening 6d, the number of balls won in the special prize opening 6d, and the like. . When it is determined that the predetermined condition is satisfied, the driving of the special prize opening driving device 6dd is controlled so as to temporarily close the special prize opening 6d.

When it is determined again that the special winning opening 6d opening condition is satisfied, the special winning opening 6d is opened by controlling the driving of the special winning opening driving device 6dd, and the special winning opening 6d is opened. The number of balls won in the winning opening 6d is counted.
Specifically, one open state is maintained until a predetermined number (for example, 10) of game balls wins the special winning opening 6d or until a predetermined time (for example, 30 seconds) elapses. This operation is set to continue up to a predetermined number of times (for example, 15 times).

In addition to this, the following configuration may be included. That is, when the vehicle passes through a specific area (which is an area for acquiring the right to continue opening, not shown) provided in the special winning opening 6d, the above open state is repeated again. During the special game, this operation is set to continue up to the predetermined number of times (for example, 15 times) on the condition that the specific region has been passed. A sensor (not shown) for detecting the passage of a game ball is provided in a specific area in the special winning opening 6d, and the detection result of the sensor is transmitted to the special game control means 24.

When the game ball passes through the normal symbol start port 6i, a detection signal at that time is transmitted from the normal symbol start port sensor 6is to the ball detection means 262. When this detection signal is received, the incoming ball detecting means 262 detects that the game ball has passed through the normal symbol starting port 6i.

(Normal symbol lottery means)
The normal symbol lottery means 263 determines a symbol to be stopped and displayed on the normal symbol variation display device 264d by lottery on the condition that the game ball has passed through the valid normal symbol start port 6i.
The normal symbol lottery means 263 includes a hit determination random number generation means, a hit determination random number value acquisition means, and a hit determination means, in the same manner as the above-described winning lottery means 22a.
That is, the normal symbol lottery means 263 generates a hit determination random number having a predetermined cycle by, for example, a software random number, and obtains a hit determination random number value when the game ball passes through the normal symbol start port 6i that is valid. Then, based on the winning determination random number value, it is determined whether the winning or not winning.

Further, the normal symbol lottery means 263 includes a stop symbol determining means for determining a symbol to be stopped and displayed on the normal symbol variation display device 264d based on the determination result of whether the winning or non-winning.
The normal symbol lottery means 263 determines the symbol to be stopped and displayed as “7” when the acquired random number for winning determination is determined to be winning. Further, the normal symbol lottery means 263 determines the symbol to be stopped and displayed as “5” or “6” when the acquired random number for winning determination is determined to be non-winning.

Here, whether the symbol “5” or “6” is selected is determined by generating a stop symbol selecting random number with the stop symbol selecting random number generating means and setting the stop symbol selecting random number value acquiring means with 1 stop symbol. Get random number for selection. Next, a stop symbol (either “5” or “6”) corresponding to the acquired random number value for selecting a stop symbol is selected.
In addition, the normal symbol lottery means 263 determines whether the winning or non-winning determination method is different according to the state of the normal symbol starting port 6i that is valid, that is, the normal probability or the high probability. Control. Although the normal probability and the high probability are the same in that the random number for winning determination is acquired when the game ball of the normal symbol start port 6i passes, the winning probabilities are made different. In this embodiment, the normal probability is set to win with a probability of 1/2, and the high probability is set to win with a probability of 9/10. That is, at the normal probability and the high probability, 1/2 and 9/10 of the acquired hit determination random values are the random values determined to be winning.

(Normal design fluctuation control means)
When the game ball passes through the normal symbol start port 6i, the normal symbol variation control means 264 performs the symbol variation display and stop display of the normal symbol variation display device 264d based on the lottery result of the normal symbol lottery means 263. Is to control.
The normal symbol fluctuation control means 264 changes the symbol of the normal symbol fluctuation display device 264d for a predetermined time, and finally causes the normal symbol fluctuation display device 264d to stop-display the symbols determined by the normal symbol lottery means 263. .

(Sphere guidance device control means)
The ball guidance device control means 265 controls the operation of the ball guidance device 265d based on the lottery result of the normal symbol lottery means 263. Specifically, when winning is made by lottery by the normal symbol lottery means 263, the ball guiding device 265d is controlled to operate. On the contrary, when the normal symbol lottery means 263 is not selected in the lottery, the ball guiding device 265d is not operated.
The timing of operation is immediately after the symbol of the normal symbol fluctuation display device 264d fluctuates for a predetermined time and the symbol determined by the normal symbol lottery means 263 is stopped and displayed on the normal symbol fluctuation display device 264d.

When the normal symbol lottery means 263 is selected, the symbol “7” is finally stopped and displayed on the normal symbol fluctuation display device 264d. Immediately thereafter, the ball guidance device control means 265 operates the ball guidance device 265d to enlarge the electric tulip 6h at the entrance portion of the start winning opening 6c.
In this embodiment, the normal symbol variation control means 264 controls to change the symbol variation time of the normal symbol variation display device 264d according to the gaming state.
First, in the normal gaming state, the time from the start of the change of the symbol by the normal symbol change display device 264d to the stop is set to 30 seconds. When the normal symbol lottery means 263 is selected, the ball guidance device control means 265 sets the time for operating the ball guidance device 265d to 0.5 seconds.

That is, the symbol change display is performed by the normal symbol change display device 264d for 30 seconds, and after the symbol is stopped and displayed, at the time of winning, the ball guiding device 265d is operated for 0.5 seconds to enter the start winning opening 6c. A state is formed in which the game balls are easy to win.
On the other hand, in the probability variation gaming state and the time shortening gaming state, the normal symbol variation control means 264 sets the time from the start of the symbol variation by the normal symbol variation display device 264d to the stop to 5 seconds. The ball guidance device control means 265 sets the time for operating the ball guidance device 265d to 3 seconds when the normal symbol lottery means 263 is selected.

That is, the symbol variation display is performed by the normal symbol variation display device 264d for 5 seconds, and after the symbol is stopped and displayed, the ball guiding device 265d is operated for 3 seconds at the time of winning and the game ball is placed in the start winning opening 6c. A state that makes it easier to win a prize is formed. Note that the crossing position selection means 22d described above can also be used for the symbol variation display by the normal symbol variation display device 264d.
As described above, in the normal gaming state, the ease of winning a game ball to the start winning opening 6c hardly changes. However, in the probability variation gaming state and the time shortening gaming state, the ease of winning the game ball to the start winning opening 6c is significantly higher than in the normal gaming state.
