Description

  The present invention relates to control of a symbol display device of a ball game machine, and more particularly to reduction of a processing load on a main board that performs symbol control.

2. Description of the Related Art Conventionally, some ball game machines are provided with a symbol display device on a board surface.
This symbol display device is a device that displays numbers from 0 to 9, or a predetermined symbol (for example, cherry, BAR, etc.) in addition to this, and includes liquid crystal, cathode ray tube, 7 segment LED, dot matrix. Or a display means such as a reel having these symbols printed on the peripheral surface of the rotary cylinder. This symbol display device is usually formed so as to display a plurality of symbols (three in many cases), but may display a single symbol.
Then, when entering a predetermined starting chucker, the symbols start to fluctuate on these display means and eventually stop at a certain symbol. At this time, if the player stops at a predetermined symbol or a combination of predetermined symbols, the player is provided with a predetermined profit state such as opening of a big prize opening.

The change or stop of the symbols in the symbol display device is controlled by a command transmitted from the main board.
For example, when changing the symbol on a screen such as a liquid crystal display, a cathode ray tube, or a dot matrix, the symbol number to be displayed every predetermined unit time and the offset value indicating the deviation from the symbol stop position are sent as commands. Is done. And the symbol display apparatus which received this will display the symbol corresponding to a symbol number for every said predetermined unit time with the shift | offset | difference according to an offset value. For this reason, when changing the symbol in a certain direction (for example, when displaying it in order like 1, 2, 3,...), The symbol number and the offset value that is changed little by little are set at predetermined unit times. By continuing to transmit to the image, an image like frame advance is displayed on the symbol display device.

  On the other hand, when a reel is used as the display means, a change in the design of the rotating reel peripheral surface is controlled by outputting a pulse from the main substrate.

Japanese Patent Laid-Open No. 10-179865 JP-A-10-127877 JP-A-6-218115 JP-A-6-246050 JP-A-8-224339 JP-A-10-113433 JP-A-5-228245

In the conventional method, the main board has to perform control to change the symbol number and the offset value little by little and control to transmit the contents during the variation of the symbol. For this reason, a large amount of communication processing capacity from the main board is divided into symbol variations, and commands other than the symbol variations (for example, appearance of a predetermined character, background change, symbol enlargement or reduction) are controlled. The type and number of transmissions were limited.
Further, since the display means for displaying an image such as a liquid crystal and the display means such as a reel have different display methods for symbol variation, the control command system on the main board has to be different.

  Therefore, the invention according to claim 1 of the present invention transmits a command instructing the change of the symbol only when changing the symbol in the ball game machine equipped with the symbol display device, and according to the command. The purpose is to reduce the communication burden of the main board in the symbol control by leaving the image display to the symbol display device.

(Claim 1)
In view of the above problems, the invention according to claim 1 of the present invention is a ball game machine having a symbol display device that displays a plurality of types of symbols in a predetermined direction and a main board, and the main board. Each of the symbol display devices has a CPU, and the CPU of the main board transmits a variation command including the variation time information of the symbols to the CPU of the symbol display device. The symbol display device has a ROM that stores stop symbol data representing a stop symbol and variation pattern data representing a variation pattern of the symbol. Is transmitted from the CPU to the CPU of the symbol display device only at the start of variation, the variation time of the symbol included in the variation time information of the variation command is set in the timer, and the passage of the time set in the timer is set. The CPU of the symbol display device that has started the measurement and receives the variation command acquires stop symbol data and variation pattern data corresponding to the variation command from the ROM, and varies from the variation start to the variation stop according to the variation pattern data. In addition to displaying, the control is performed so that the stop symbol is displayed according to the stop symbol data. When the time measured by the timer reaches the set time, the main board CPU issues a symbol stop command from the CPU. After receiving the symbol stop command transmitted to the display device CPU, the symbol display device CPU stops the stop symbol related to the stop symbol data at the position where it should be stopped, and measures it with the timer of the main board. Even if the time has reached the point of time when the symbol has changed and the point where it should be stopped is still continuing, PU is characterized by the formation so as to stop the symbols of the stop symbol data by receiving the symbol stop command from the main board.

The “design display device” is a device that displays an image as an image using a liquid crystal, a cathode ray tube, a dot matrix, or the like, and a symbol that is printed on a peripheral surface of a rotating cylinder, such as that used in a slot machine. Refers to the device.
The “symbol” refers to a number or other characters, symbols, or other symbols, including symbols such as cherry and BAR. In addition, these symbols are arranged such that a plurality of elements are arranged one-dimensionally and the first element appears again after the last element (hereinafter referred to as “circular arrangement”). Also good. A plurality of symbols may appear at random.

The “predetermined direction” may be one direction or both directions. Therefore, it is also possible to set so as to change in the downward direction under normal conditions.
“Variation display” means that, for example, the symbol fluctuates as the reel rotates. In the symbol display device according to the present invention, the symbols gradually disappear as they are gradually shifted downward or upward. At the same time, the following symbols will appear little by little from the top or bottom.
The “stop symbol” refers to a symbol that is finally displayed by the symbol display device after the variation of the symbol.

The “stop symbol data” refers to data representing the above stop symbol. This stop symbol data is expressed as stop symbol image data in the case of displaying a symbol such as a liquid crystal image. Further, a reel that displays an actually printed pattern can be represented as data indicating a rotation angle from a predetermined reference point, for example.
The “variation pattern” refers to a pattern variation pattern. For example, it shows a change in the speed of fluctuation related to the symbol fluctuation, and the order of stopping when a plurality of symbols are displayed.
“Variation pattern data” refers to data representing the above variation pattern. For example, it is represented by data indicating the change in the speed of fluctuation related to the symbol fluctuation, and the order of stopping when a plurality of symbols are displayed.

“Main board” refers to an IC board having a CPU and a program ROM. This main board is to transmit the above variation command to the symbol display device. .
"Data storage means" refers to a storage device such as a ROM that stores the above stop symbol data and variation pattern data. This data storage means is provided in the symbol display device.
In addition, the symbol display device is provided with a CPU for controlling the actual variation of symbols separately from the CPU of the main board.
In the present invention, it is sufficient for the main board to transmit a variation command at the start of the symbol variation state, and it is not necessary to constantly transmit a symbol to be displayed and data corresponding to the variation pattern. Can be reduced.

Further, if the variation pattern is the same, the control of the actual symbol display corresponding to the variation pattern is left to the CPU of the symbol display device. Therefore, as the symbol display device, a symbol such as a liquid crystal is displayed as an image. Even if there is an actual symbol such as a reel, control can be performed with the same variation command.
Further, the “production pattern” refers to a production pattern related to the variation of the design. For example, when displaying three symbols, when two symbols are stopped, depending on the other symbol, when it becomes a specific arrangement (so-called reach state), the display of the background can be changed, or a predetermined character can be changed. There is an effect to make it appear and inform the player to that effect.

“Production pattern data” refers to data representing the production pattern. For example, it is represented by data indicating a change in the background of the symbol, a motion of a predetermined character, or the like.
Further, according to the present invention, the symbol should be originally stopped due to a difference in CPU clock frequency between the main board and the symbol display device, a deviation in command transmission timing, a deviation in rewrite timing of the display screen, etc. It can be assumed that the vehicle stops at a position deviating from “position”), or that fluctuations are still continuing even when the time point at which it should be stopped is reached.
Therefore, in the ball game machine according to the present invention, the main board transmits a symbol stop command to the CPU of the symbol display device after the time required for the designated variation pattern has elapsed since the variation command is transmitted, and The CPU of the symbol display device that has received the stop command stops the stop symbol at the normal position.

Here, the “symbol stop command” is a command that the main board transmits to the symbol display device separately from the variation command, and is a command for stopping the symbol variation in the symbol display device.
In the ball game machine according to the present invention, the variation of the symbol is controlled as follows.
First, at the start of symbol variation, the main board transmits a variation command to the symbol display device, and the symbol display device that has received the variation command varies symbols according to the variation command.
Then, after the time required for the variation pattern designated by the variation command (hereinafter referred to as “variation required time”) has elapsed, the main board transmits the symbol stop command to the CPU of the symbol display device.

The symbol display device should stop the fluctuation at the stop symbol through the symbol fluctuation according to the predetermined fluctuation pattern during this fluctuation time, but for the above reason, the stop position is slightly changed from the normal position. It may shift.
Here, the CPU of the symbol display device that has received the symbol stop command moves the symbol from the stop position to the normal position.
Thereby, it is possible to eliminate a subtle shift in the display of the stop symbol.

Since this invention is comprised as mentioned above, there exists an effect described below.
That is, according to the description of the invention of claim 1, in the ball game machine equipped with the symbol display device, only when the symbol is changed, a command instructing the symbol change is transmitted and the command corresponding to the command is transmitted. By leaving the image display to the symbol display device, it becomes possible to reduce the communication burden of the main board in the symbol control.

Broken lines indicate high speed fluctuations. It is a schematic diagram which shows the structure of a fluctuation command.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a functional block diagram schematically showing the present embodiment.
As shown in FIG. 1, the ball game machine according to the present embodiment includes a starter chucker 60, a main board 50, and a symbol display device 10.
The “starting chucker” is provided at a winning opening for operating the symbol variation of the symbol display device 10. When a ball enters the starter chucker 60, a ball entry signal is sent to the CPU 51 of the main board 50 described below.
The “main board” is an electronic control circuit board in which software for controlling the operation of the ball game machine is stored. The CPU 51, a random number ROM 53 for generating random numbers, and a program ROM 52 for storing programs are mounted. Yes.

The “symbol display device” is a device that displays a design on a liquid crystal screen, and includes a liquid crystal screen 16 that displays the design, a CPU 11 that controls the design displayed on the liquid crystal screen 16, a stop design, and a variation pattern of the design And a data ROM 12 as data storage means for storing data relating to the production pattern. As the symbol display device 10, in addition to a device that displays an image on a liquid crystal screen, a device that displays a symbol as an image, such as a cathode ray tube, a 7-segment LED, or a dot matrix, can be used.
Next, an outline of control of the ball game machine according to the present embodiment will be described with reference to FIG.

The CPU 51 of the main board 50 controls the operation of the accessory of the ball game machine according to the program recorded in the program ROM 52.
When there is a ball entering the starting chucker 60, a ball entering signal is transmitted from the starting chucker 60 to the CPU 51 of the main board 50.
The CPU 51 of the main board 50 that has received the incoming signal determines the combination of the stop symbol, the variation pattern, and the effect pattern according to the random number generated by the random number ROM 53.
Then, a code designating these combinations is transmitted as a change command 40 from the CPU 51 of the main board 50 to the CPU 11 of the symbol display device 10 at the start of the change.

The CPU 11 of the symbol display device 10 that has received this variation command 40 designates the stop symbol data 13 specified by the stop symbol code 43, the variation pattern data 14 specified by the variation pattern code 44, and the effect pattern code 45 from the data ROM 12. The production pattern data 15 to be acquired is acquired. Then, based on the acquired data, the designated stop symbol is displayed on the liquid crystal screen 16 with the designated variation pattern and effect pattern.
The liquid crystal screen 16 of the symbol display device 10 has an appearance as shown in FIG. This liquid crystal screen has a pattern 30 (hereinafter “left symbol” in order from the left) in each of three display frames 20 (hereinafter referred to as “left frame”, “middle frame”, and “right frame” in order from the left). "," Middle symbol ", and" right symbol ") are displayed to represent a three-digit symbol 30. Each symbol 30 changes in order from the numbers “0” to “9”, and after “9”, changes to “0” again.

FIG. 3 conceptually illustrates the fluctuation and stoppage of the symbol 30. The fluctuation and stop of the symbol 30 will be described with reference to this figure and FIG. 4 schematically illustrating the fluctuation of the symbol 30. FIG.
Initially, each symbol 30 is in a stopped state (FIG. 4A). From this state, entering the predetermined starting chucker 60 starts the fluctuation of the symbol 30 (a in FIG. 3, b in FIG. 4).
Each symbol 30 fluctuates at a low speed immediately after the start of fluctuation, but soon enters a high-speed fluctuation (b in FIG. 3, b in FIG. 4).
Then, first, the left symbol 31 again slows down (Fig. 3c, Fig. 4d) and stops (Fig. 3d, Fig. 4e). At this time, the middle symbol 32 and the right symbol 33 maintain high-speed fluctuations.

Next, the middle symbol 32 again slows down (e in FIG. 3, f in FIG. 4) and stops (f in FIG. 3, f in FIG. 4). At this point, the right symbol 33 maintains high speed fluctuation.
Finally, the right symbol 33 again slows down (g in FIG. 3, FIG. 4 h) and stops (h in FIG. 3, r in FIG. 4).
Then, all the symbols 30 are stopped again (i in FIG. 3).
In the present embodiment, the CPU on the main board transmits the variation command 40 at the time point a in FIG.
The configuration of the variable command 40 is composed of a total of six segments, as shown in FIG.

<1> indicates a change start command 41 indicating the head of the change command 40.
<2> indicates a left symbol code 43a that designates a stop symbol of the left symbol 31.
<3> indicates a middle symbol code 43b for designating a stop symbol of the middle symbol 32.
<4> indicates a right symbol code 43c that designates a stop symbol of the right symbol 33.
Stop symbol data 13 corresponding to the left symbol code 43a, middle symbol code 43b, and right symbol code 43c is recorded in the data ROM 12 of the symbol display device 10. For example, when the stop symbol is “7”, a code designating “7” is determined as the stop symbol code 43. The image data for actually displaying “7” is recorded as stop symbol data 13 in the data ROM 12.

  <5> indicates a variation pattern code 44 that designates a variation pattern of the symbol 30. This designates a change pattern of the fluctuation speed and a stop order pattern of the symbol 30. For example, in the example of the symbol variation described above, a pattern as shown in Table 1 below is designated by the variation pattern code 44.

上記の変動パターンを表示するデータは、図柄表示装置10のデータＲＯＭ12に、変動パターンデータ14として記憶されている。なお、同表中の最左列の符号は、図３の符号と対応している。
また、図５の＜６＞は、演出パターンコード45を示す。これは、図柄30の背景等の演出を指定するコードである。たとえば、二つの図柄30が停止した際に、あと一つの図柄30次第では特定の配列になる場合（いわゆるリーチ状態）に遊技者にその旨を知らせる演出がある。この演出パターンコード45で指定されるデータは、図柄表示装置10のデータＲＯＭ12に、演出パターンデータ15として記憶されている。

The data for displaying the variation pattern is stored as variation pattern data 14 in the data ROM 12 of the symbol display device 10. In addition, the code | symbol of the leftmost column in the table respond | corresponds with the code | symbol of FIG.
Also, <6> in FIG. This is a code that specifies an effect such as the background of the symbol 30. For example, when two symbols 30 are stopped, there is an effect of notifying the player when the symbols 30 are in a specific arrangement depending on the other symbol 30 (so-called reach state). The data specified by the effect pattern code 45 is stored as effect pattern data 15 in the data ROM 12 of the symbol display device 10.

(Processing procedure)
The processing in the main substrate 50 is shown in the flowchart of FIG. Hereinafter, processing in the main substrate 50 will be described with reference to FIG.
First, when a ball enters the starter chucker 60, a random number is generated on the main board 50 (S100), and a stop symbol, a variation pattern, and an effect pattern are determined accordingly (S101).
Then, the time required for the variation pattern and the effect pattern is determined (S102). This time is set in a timer provided in a RAM (not shown) of the main board 50 (S103).
Thereafter, a variation command 40 including a stop symbol code 43, a variation pattern code 44, and an effect pattern code 45 is transmitted to the CPU 11 of the symbol display device 10 (S104). Then, the time required for change set in the timer is subtracted (S105), and it is determined whether or not the required time for change has passed (S106). If it has not yet elapsed, the subtraction of the time required for variation is continued (S105). During the time required for the change, the symbol display device 10 changes the symbol in accordance with the change command.

If it is determined in S106 that the required time has elapsed, a symbol stop command is transmitted from the main board 50 to the symbol display device 50 (S106). The symbol stop command is a symbol that is intended to stop the symbol 30 due to a difference in clock frequency between the CPU 51 of the main board 50 and the CPU 11 of the symbol display device 10, a shift in command transmission timing, a shift in rewrite timing of the display screen, or the like. This is to prevent the stop position from deviating from the position. The CPU 11 of the symbol display device 10 that has received this symbol stop command changes the symbol to the stop symbol regardless of the symbol 30 displayed at the time of reception, and then stops the stop symbol at the normal position. ing.
The processing on the main board 50 is thus completed. However, when the starting chucker 60 again enters the ball, the processing is repeated according to the above procedure.

Here, again, the procedure of the process in the example of the symbol variation shown in FIG. 4 will be described with reference to FIGS. 2 and 5 as appropriate.
First, the previous stop symbol (in this example, “823”) is displayed on the symbol display device 10 until the starting chucker 60 enters the ball (FIG. 4A).
When the ball enters the starting chucker 60, the stop symbol is determined by a random number on the main board 50 (S100 in FIG. 2). For example, when “456” is determined as the stop symbol, the stop symbol of the left symbol 31 is “4”, the stop symbol of the middle symbol 32 is “5”, and the stop symbol of the right symbol 33 is “6”. Become. In addition to this, a variation pattern and an effect pattern are also determined. This is the stage shown in S101 of FIG.

Then, the time required for the variation pattern and the effect pattern is determined (S102 in FIG. 2), and this variation required time is set in the timer of the main board 50. This is the stage shown in S103 of FIG.
Then, a variation command 40 designating the stop symbol code 43, the variation pattern code 44, and the effect pattern code 45 is transmitted from the main board 50 to the CPU 11 of the symbol display device 10. This is the stage shown in S104 of FIG. Thereafter, in the main board 50, the required time for fluctuation is monitored in the steps S105 and S106, but the command transmission to the symbol display device 10 relating to the symbol fluctuation is not performed during this time.

The symbol variation during this period is controlled by the symbol display device 10 itself.
That is, the CPU 11 of the symbol display device 10 that has received the variation command 40 acquires a variation pattern corresponding to the variation pattern code 44 from the data ROM 12. In the following description, it is assumed that the pattern shown in Table 1 has been acquired.
First, according to the data “B” in Table 1, each symbol 30 is fluctuated at a low speed. That is, the symbol display device 10 starts changing at a low speed from the symbol 30 currently displayed in each display frame 20 at a low speed (FIG. 4B).
Next, according to the data “c” in Table 1, each symbol 30 is changed at high speed. That is, the symbol display device 10 starts changing at a high speed downward from the currently displayed symbol 30 in each display frame 20 (FIG. 4C).

Next, according to the data “d” and the left symbol code 43a in Table 1, the left symbol 31 is moved slowly toward the stop symbol “4”, and the middle symbol 32 and the right symbol 33 are changed at high speed. That is, the symbol display device 10 starts low-speed fluctuation toward the stop symbol “4” in the left frame 21. However, the middle frame 22 and the right frame 23 still maintain high-speed fluctuations (Fig. 4D).
Next, according to the data of “e” and the left symbol code 43a in Table 1, the left symbol 31 is set to the stopped state of the stop symbol “4”, and the middle symbol 32 and the right symbol 33 are changed at high speed. That is, the symbol display device 10 displays the stop state of the stop symbol “4” in the left frame 21. However, the middle frame 22 and the right frame 23 still maintain high speed fluctuations (Fig. 4E).

Next, according to the data of “F” in Table 1, the left symbol code 43a and the middle symbol code 43b, the left symbol 31 is set to the stop state of the stop symbol “4”, and the middle symbol 32 is moved toward the stop symbol “5” at a low speed. While moving, the right symbol 33 is changed at high speed. That is, the symbol display device 10 displays the stop state of the stop symbol “4” in the left frame 21. Further, in the middle frame 22, low speed fluctuation is started toward the stop symbol “5”. However, the high-speed fluctuation is still maintained in the right frame 23 (figure 4).
Next, according to the data of “G” in Table 1, the left symbol code 43a and the middle symbol code 43b, the left symbol 31 is set to the stop state of the stop symbol “4”, and the middle symbol 32 is set to the stop state of the stop symbol “5”. At the same time, the right symbol 33 is changed at high speed. That is, the symbol display device 10 displays the stop state of the stop symbol “4” in the left frame 21. The middle frame 22 also displays the stop state of the stop symbol “5”. However, the high-speed fluctuation is still maintained in the right frame 23 (Fig. 4G).

Next, according to the data of “Chi” in Table 1, the left symbol code 43a, the middle symbol code 43b, and the right symbol code 43c, the left symbol 31 is set to the stop state of the stop symbol “4”, and the middle symbol 32 is set to the stop symbol “5”. And the right symbol 33 is moved at a low speed toward the symbol “6”. That is, the symbol display device 10 displays the stop state of the stop symbol “4” in the left frame 21. The middle frame 22 also displays the stop state of the stop symbol “5”. Then, in the right frame 23, low speed fluctuation is started toward the stop symbol “6” (FIG. 4C).
Next, according to the “Li” data in Table 1 and the left symbol code 43a, middle symbol code 43b, and right symbol code 43c, the left symbol 31, the middle symbol 32, and the right symbol 33 are set to the stop symbols “4”, “5”, and The stop state is “6”. That is, the symbol display device 10 displays the stop state of the stop symbol “4” in the left frame 21. The middle frame 22 also displays the stop state of the stop symbol “5”. Further, the stop state of the stop symbol “6” is also displayed in the right frame 23 (see FIG. 4).

  At this point, there may be a situation where the symbol variation has not stopped due to a difference in clock frequency between the CPU 51 of the main board 50 and the CPU 11 of the symbol display device 10, a shift in command transmission timing, a shift in rewrite timing of the display screen, or the like. . At this time, it is determined that the required variation time has elapsed in step S106 in FIG. Therefore, the main board 50 transmits a symbol stop command to the symbol display device 10. This is the stage shown in S107 of FIG. Receiving this, the symbol display device 10 stops the fluctuation at the normal position with the stop symbol “4” in the left frame 21. In the middle frame 22, the change is stopped at the normal position by the stop symbol “5”. Further, in the right frame 23, the change is stopped at the normal position by the stop symbol “6”. As a result, the stop symbol is displayed at the normal position without any deviation. This state is maintained until the player enters the starting chucker 60 again.

(Modification)
In the above description, the change stops in the order of the left symbol 31, the middle symbol 32, and the right symbol 33. Of course, the change is not limited to this order, and the stop order is arbitrarily designated by the change command 40. Is possible.
In addition, each symbol 30 is changed from a stopped state to a high-speed variation through a low-speed fluctuation, and then again to a stopped state through a low-speed fluctuation, but of course this is not limited to this pattern. It is also possible to specify a pattern that starts changing again with the change command 40.

Furthermore, the changing direction of the symbol 30 can be changed not only downward but also upward.
Further, in the above description, the production with the production pattern code 45 is not particularly mentioned, but various production patterns (for example, predetermined characters appear in the reach state in the data ROM 12 of the symbol display device 10). Or production pattern data 15 corresponding to the production such as changing the background) can be stored, and these data can be designated by the production pattern code 45.
Furthermore, in the present invention, since it is sufficient to transmit the variation command 40 at the start of symbol variation, the symbol variation such as causing a predetermined character to appear separately from the effect pattern code 45 at other times than the transmission Commands related to performances that are not directly related can be transmitted.

In the above embodiment, the symbol 30 changes while changing the changing speed according to a fixed circulation arrangement. However, it is also possible to display while replacing with an image showing a predetermined symbol variation every time the symbol variation is switched. For example, when stopping at the stop symbol “5” after changing from high speed to low speed, even if the symbol “7” is displayed when the variation command 40 is received, the symbol “1” is displayed at the next moment. Alternatively, image data that gradually decreases the fluctuation speed toward the symbol “5” may be acquired from the data ROM 12 and displayed.
Further, the timing of symbol variation is not limited to that shown in FIG. For example, it is possible to specify the change command 40 so that the middle symbol 32 shifts to the low-speed fluctuation at the timing e while the left symbol 31 is changing from c to d. Similarly, it is possible to specify the change command 40 so that the right symbol 33 shifts to the low-speed fluctuation at the timing of g while the middle symbol 32 is changing at low speed from e to f.
