2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, a symbol starting means, a symbol variation displaying means, a special winning means and the like are arranged on a game board, and on condition that the symbol starting means detects a game ball, When the symbol of the symbol variation display means scrolls and fluctuates for a predetermined time and stops, and when the stopped symbol becomes a big hit symbol, a profit state which is advantageous to the player, such as opening the big win means as a so-called big hit for a predetermined time. Is to be generated.

The symbol variation display means has one or a plurality of, for example, three symbol display portions, and when the symbol starting means detects a game ball, the symbols on the three symbol display portions are displayed at high speed and medium speed. In the conventional ball game machine, all processing is performed on the main control unit side, and during the fluctuation operation of the symbol fluctuation display unit, the main control unit changes the symbol fluctuation display unit. While constantly transmitting a signal to the symbol variation control means, the symbol of the symbol variation display means is controlled.

For example, when the symbol of the symbol variation display means is varied by a predetermined time in a permutation pattern in a variation pattern such as a high speed, a medium speed, and a low speed, the symbol fluctuates in a variation pattern such as a high speed, a medium speed, and a low speed. Each time is started, a control signal is sent from the main control unit to the symbol variation control unit, and the symbol of the symbol variation display unit is variation-controlled in a predetermined order by the control signal.

[0005]

Sends a control signal to the symbol variation control means to control the symbol on the symbol variation display means. For this reason, when diversifying the symbol variation pattern, or when the symbol is varied in a complicated manner by combining a plurality of types of variation patterns in a predetermined permutation, a control signal transmitted from the main control unit to the symbol variation control unit. However, there is a disadvantage that the data amount is extremely large. Therefore, in the conventional control method, there is naturally a limit in diversifying the pattern variation pattern of the symbol variation display means.

In view of such a conventional problem, the present invention can simplify the signal transmitted from the main control means to the symbol variation control means, and can easily promote the diversification of symbol variations of the symbol variation display means. It is an object of the present invention to provide a symbol variation control method for a ball and ball game machine.

The first processing system 27 includes a jackpot determination processing means 33.
And a fluctuation command signal generating means 34 and a profit state generating means 35. The big hit determination processing means 33 determines whether or not to display a big hit symbol on the stop symbol of the first symbol change display means 21 by a random number process, on condition that the first symbol starting means 14 detects a game ball. Then, for example, a jackpot random number of 1 to 300 is generated, and when the first symbol starting means 14 detects a game ball, the random number value of the jackpot random number is extracted, and when the random number value is the jackpot determination value, It is determined to be a big hit, and when it is other than the big hit determination value, it is determined to be out.

The variation command signal generation means 34 has a plurality of types of variation command signals set on condition of the processing result of the jackpot determination processing means 33, and when a certain processing result is output, the processing result is added to the processing result. A corresponding variation command signal is transmitted to the first symbol variation control means 36.

It has a function of controlling the opening and closing operation to be continued up to a predetermined number of times.

The first symbol change control means 36 is a liquid crystal display means.
In addition to a liquid crystal driving unit 37 that drives the liquid crystal display unit 20 including the thirteenth first symbol variation display means 21, a pattern permutation storage unit 38, a display symbol storage unit 39, and a variation control unit 40 are provided. The first symbol variation control means 36 is constituted by a CPU, a ROM, a RAM, and other electric components mounted on the symbol variation control board, and is mounted on the back side of the liquid crystal display means 13.

The pattern permutation storage section 38 is for storing a pattern fluctuation pattern permutation obtained by combining a plurality of types of fluctuation patterns in a predetermined permutation in time series. The pattern permutation storage section 38 is constituted by a ROM or the like. , First to fifth
In accordance with the variation command signals 34a to 34e, data of five types of symbol variation patterns of the first to fifth pattern sequences 38a to 38e are stored in advance by a program or the like.

For example, the variation pattern of the first symbol of the first symbol variation display means 21 includes a high-speed pattern in which the first symbol is scrolled at a high speed, a medium-speed pattern in which the first symbol is scrolled in a medium speed, and a scroll variation in a low speed. There are four types (a plurality of types) of symbol variation patterns: a low-speed pattern and a swing pattern for swinging the first symbol up and down or left and right.

The first to fifth pattern permutations 38a to 38e
Is configured by combining four types (a plurality of types) of symbol variation patterns in a predetermined order in a time-series manner. For example, as shown in FIG. 4, the first pattern permutation 38a has a high speed, a medium speed,
The second pattern permutation 38b
Is a high-speed, medium-speed, sway, and low-speed fluctuation pattern, the third pattern sequence 38c is a high-speed, sway, medium-speed, and low-speed fluctuation pattern, and a fourth pattern sequence 38d is a high-speed, low-speed, medium-speed, and sway. The fifth pattern permutation 38e is a high-speed
Each variation pattern of swing, low speed, and swing is combined in the permutation.

When changing the first symbol of the first symbol variation display means 21 in each of the symbol variation patterns of the high-speed pattern, the medium-speed pattern, the low-speed pattern, and the swing pattern, the display symbol storage section 39 stores the first symbol in the first symbol variation display means 21. Symbol data such as a plurality of types of symbols and stop symbols to be displayed are programmed.

The fluctuation control unit 40 is based on a fluctuation command signal transmitted from the fluctuation command signal generating means 34 of the main control means 26 on condition that the first symbol starting means 14 detects a game ball. The function of reading out the symbol variation pattern permutation corresponding to the variation command signal from the pattern permutation storage unit 38, and a plurality of types of symbols stored in the display symbol storage unit 39, from among symbol data such as stop symbols, The function of extracting and reading the symbol data of the first symbol actually displayed on the first symbol variation display means 21 by random number processing or the like, and the first symbol variation display means 21 of the liquid crystal display means 13 according to the symbol variation pattern permutation and the symbol data. And a function of controlling a background image, a demonstration image, and the like of the liquid crystal display unit 20 of the liquid crystal display unit 13.

It should be noted that the first symbol variation control means 36 determines a predetermined number (for example, 4) when the first symbol activation means 14 detects a winning of a game ball during the variation operation of the first symbol variation display means 21.
), And the first prize within the range of the stored number.
The fluctuation / stop is continued after the fluctuation of the symbol fluctuation display means 21 is completed.

Next, the operation of the above-mentioned ball game machine will be described. When the firing handle 10 of the firing means 9 is operated with the game ball on the upper plate 7, the game ball on the upper plate 7 is
The game balls are supplied one by one in association with the launch operation of No. 9 and the game balls are hit with a hitting hammer and sequentially fired along the guide rail 11 toward the game board 4.

While the game ball fired on the upper side of the game board 4 falls along the surface of the game board 4, the game ball is
When passing through the symbol starting means 16, the second symbol variation control means 31
Works to change the second symbol of the second symbol change display means 22 for a predetermined time. On the other hand, when the second symbol starting means 16 detects a game ball, the hit determination processing means 30 extracts a random value of the hit random number and makes a hit determination based on whether or not the hit value is a hit value. Stopping of the two symbol variation display means 22 is stopped so that the predetermined symbol is displayed.

When the stop symbol of the second symbol variation display means 22 becomes a hit symbol, the open / close control means 32 operates and the pair of open / close claws 23 of the first symbol start means 14 is opened. For this reason, a game ball can be easily won in the first symbol starting means 14, and the first symbol of the first symbol change display means 21 can be easily changed accordingly.

When the opening / closing claw 23 of the first symbol starting means 14 is released and the game ball wins, the big hit determination processing means 33 performs a big hit determination processing, and after the first symbol change display means 21 changes, the first symbol is displayed. It is determined whether to stop at the big hit symbol. That is, the big hit determination processing means 33 randomly selects a big hit random number at the time when the first symbol starting means 14 detects the game ball, and determines that the big hit is the big hit if the random number value is the big hit determination value. Then, the first symbol variation control means 36 operates according to the determination result, and after the first symbol of the first symbol variation display means 21 varies for a predetermined time in accordance with a predetermined symbol variation pattern permutation as described later, "7/7. Stop at a jackpot symbol such as "7". If it is other than the jackpot determination value, it is determined to be out of place, and after fluctuating according to a predetermined symbol variation pattern permutation,
The first symbol comes off and stops at the symbol. When the symbols are stopped, a symbol determination signal is sent almost simultaneously with the end of the variation by the symbol variation pattern permutation, and the symbols are stopped at the symbol determined by the determination signal.

If the stop symbol of the first symbol variation display means 21 indicates a big hit symbol, the profit state generating means 35 operates to convert and drive the variable winning means 15 to the first state in which the opening and closing plate 24 is opened forward. For this reason, most of the game balls falling from the upper side of the game board 4 easily enter the variable winning means 15 via the opening / closing plate 24. Then, when the game ball wins the variable winning means 15, the payout means is operated by the payout control means,
15 prize balls are paid out for each winning ball.
Therefore, once a big hit occurs on the first symbol change display means 21 side, a great profit is returned to the player.

The variable winning means 15 closes the opening / closing plate 24 when ten game balls win or when a predetermined time has elapsed. Then, if the winning game ball passes through the specific area 25 while the opening and closing plate 24 is open, the variable winning means 15 opens again,
The opening and closing operation is repeated up to 16 times.

If the result of the determination by the jackpot determination processing means 33 is a jackpot, the variation command signal generating means 34 sends a first variation command signal 34a to the first symbol variation control means 36 from the random number at that time. Then, the first symbol change control means 36 changes the change control unit 40 based on the first change command signal 34a.
Reads out the first pattern permutation 38a from the pattern permutation storage unit 38, and performs “7.7.
The first symbol of the first symbol change display means 21 is controlled so as to stop at a big hit symbol such as "7".

That is, the variation control unit 40 operates as a pattern permutation storage unit.
When the first pattern permutation 38a of 38 is read, the liquid crystal driver 37
, The first symbol of the first symbol variation display means 21 scrolls for a predetermined time in a high-speed pattern that cannot be visually confirmed. Then, when the fluctuation time in the high-speed pattern elapses, the first symbol scrolls and fluctuates for a predetermined time in the medium-speed pattern, and then shifts to a scroll fluctuation in a low-speed pattern such that the first symbol can be visually confirmed.

In this case, since the stop symbol displays a big hit symbol, the first symbol displays a reach symbol when the pattern changes at a low speed pattern. When the scroll change in the low-speed pattern is completed, the pattern shifts to a swing pattern, and the first symbol slowly swings in the up and down direction in the reach state, and then stops at the big hit symbol.

The jackpot determination processing means 33 determines that it has come off,
When the fluctuation command signal generating means 34 transmits the second fluctuation command signal 34b to the first symbol fluctuation control means 36, the fluctuation control section
40 is the second pattern permutation 38 of the pattern permutation storage unit 38
b is read out, and the first symbol of the first symbol variation display means 21 fluctuates in a time-series manner in each of the high-speed / medium-speed / shake / low-speed variation patterns and stops at the off symbol.

Therefore, the fluctuation command signal generating means 34 of the main control means 26 outputs the fluctuation command signal containing no time element to the first.
Just by transmitting the symbol variation to the symbol variation control unit 36, the variation control unit 40 of the first symbol variation control unit 36 reads out the symbol variation pattern permutation including the temporal element stored in the pattern permutation storage unit 38, and reads the symbol variation. According to the pattern permutations 38a to 38e, the first symbol of the first symbol variation display means 21 can be controlled while being changed in time series into a plurality of types of variation patterns. Compared with the case where the first symbol of the display means 21 is controlled, the data amount of the variation command signals 34a to 34e transmitted from the variation command signal generating means 34 to the first symbol variation display means 21 is reduced, and the symbol variation is reduced. Diversification can be easily achieved. In other words, it is possible to give variations to the symbol variation while minimizing the command signal from the main control means 26.

This embodiment includes the following inventions. That is, the first invention transmits a signal from the main control means 26 for controlling the game operation to the symbol variation control means 36 on condition that the symbol starting means 14 detects a game ball, and the symbol variation display means 21 In the symbol variation control method for a ball game machine, the symbol variation pattern sequence corresponding to the variation command signal transmitted from the main control means 26 is stored in the symbol variation control means 36 in advance, and the main control A predetermined variation command signal is transmitted from the means 26 to the symbol variation control means 36, and the symbol of the symbol variation display means 21 is varied according to the symbol variation pattern permutation stored in the symbol variation control means 36 by the variation command signal. is there.
