Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine which executes a series of game programs at predetermined time intervals by resetting, timer interruption, etc., and more particularly to a variable display device capable of displaying a plurality of types of variable display modes. The present invention relates to a gaming machine that can generate a specific gaming state advantageous to a player when a display result of identification information to be displayed becomes a predetermined specific display result.

[0002]

2. Description of the Related Art In a pachinko machine or the like having a game control means for controlling the progress of a game in a game area formed on a game board, a game control executed by the game control means as a conventionally known control method. In order to prevent the process from running out of control due to noise or the like generated from a ball or the like circulating in the island facility and causing an abnormal situation, a reset is performed at regular time intervals (for example, every 4 msec) and reset. Control is performed by the reset method in which control is started from the beginning of the program every time.

In the current pachinko machines, for example, a fluctuating display device for performing fluctuating display performs a fluctuating display game in which a symbol fluctuates based on a prize at a starting port, and derives a specific display mode such as a slot-eye. There is a game machine in which a jackpot or the like that opens a special winning opening is given to a player (so-called one kind of pachinko machine).

[0004] In such a pachinko machine, whether or not to generate a big hit is generally determined by a big hit random number value obtained by a game.
Using a counter that adds “1” for each reset and becomes an initial value (0) when the value exceeds a predetermined value, the value obtained by changing the acquisition timing of the value of the counter has randomness. (A so-called +1 random number generation method). In particular, when timing related to a game ball such as a timing of winning a game ball to a starting port, which is completely asynchronous with the operation clock of the control system, is used as the acquisition timing of the random number counter value, the most reliable randomness is obtained. can get.

The big hit random number is acquired when the player wins the starting opening, and is compared with a big hit judgment random value (for example, "7") at the time of judgment (for example, at the start of the variable display). When it is determined that there is, the control is performed such that the stop symbol stops at the big hit symbol in the variable display game by the variable display device, and when it is not determined that it is the big hit, the stop symbol is stopped with the loss symbol in the variable display game. Is controlled.

As the random numbers used during the operation of the pachinko machine, there are a plurality of random numbers such as a random number for creating a jackpot symbol, a random number for creating a lost symbol, a random number for displaying a reach variation, a random number for reaching a notice, and a random number for positive variation. In a conventional pachinko machine, generally, all of these random numbers are generated by the above-mentioned +1 random number generation method, and each random number value is obtained at a predetermined obtaining timing.

As described above, in the pachinko machine, various random numbers are acquired under predetermined conditions such as winning in the starting port, and when the random numbers fluctuate, the random numbers are compared and determined, so that loss variation,
A variety of variation display games, such as reach loss variation and big hit variation, are executed to provide an interesting and entertaining game that makes it difficult for players to get bored. For example, even if the loss is changed, the reach state is not reached, but some effect (for example, when the design changes from the low-speed change state to the stop state, the state in which the two patterns have been advanced and then stopped is changed to 4). There are several types of “slipping pattern” effects that stop after passing more frames of the pattern, etc.). is there.

[0008]

In the prior art, however, the distribution of a large number of effects (variable display modes) of dozens of types corresponds to the number of effects (numbers or types) using one random number. This was performed by comparing each of the determined values.

In this case, since it is necessary to compare the random number value and each judgment value one by one, processing time is required, and there is a disadvantage that the number of effects cannot be increased much.

That is, for example, when 50 kinds of variable display modes are to be sorted, and when a total of 50 judgment values are used by associating the judgment values with each of the variable display modes, a maximum of 5 judgment values is used.
It is necessary to perform a process of comparing all zero determination values with random numbers (for example, 0 to 999). Therefore, in a game machine or the like having a specification in which the execution time of the entire program is determined in advance, for example, a reset interrupt is input every few milliseconds, if too much time is taken to distribute the above fluctuations, a series of program There is a possibility that a reset interrupt may be input before the process is completed, and the process may not be completely completed.

Further, in order to prevent such a situation from occurring, it is necessary to take measures such as simplifying other processes, and it is conceivable that a required game process or effect process cannot be performed sufficiently.

[0012] Further, in order to surely complete processing involving the distribution of a number of variable display modes within a reset cycle,
A high-speed arithmetic processing unit (CPU) is required, which leads to an increase in the price of gaming machines, and a desired high-speed CP under various regulations.
In many cases, U cannot be adopted.

The present invention has been made in view of the above-described problems, and has as its object to provide a gaming machine capable of distributing a large number of variable display modes in a short time without using a high-speed CPU. .

[0014]

In order to achieve the above object, the present invention provides a variable display device (102) capable of displaying a plurality of types of variable display modes. In a gaming machine capable of generating a specific gaming state advantageous to a player when a display result is obtained, a plurality of variable display mode determination random numbers for determining a predetermined variable display mode from among a plurality of variable display modes are provided. The random number management updating means (steps S1 to S15 in FIG. 6) which manages and updates by grouping each type of variable display mode and the random number management updating means based on the satisfaction of a specific condition. Management information extracting means (gaming microcomputer 211) for extracting management information; and determining a variable display mode based on the management information extracted by the management information extracting means. And a display control means (special symbol display device 400) for displaying the variable display mode determined by the variable display mode determining unit on the variable display device. I made it.

Here, the variable display mode refers to a state from the start of the change of the symbol to the stop of the change.
For example, various modes such as a loss variation, a reach loss variation, and a big hit variation are included.

[0016] According to this, the distribution of the variable display mode is performed by a method of extracting the management information pre-grouped for each variable display mode. It is not necessary to perform a process of comparing each determination value with the corresponding determination value, and it is possible to reduce the time required for sorting the variable display modes.

Therefore, even if a high-speed CPU is not used, it is possible to increase the number of variable display modes such as a losing variation symbol, a reach losing variation symbol, a big hit variation symbol, and the like, thereby further diversifying the effects and increasing interest. Can be increased.

It is to be noted that the management information can include information for limiting the range of the random number value and information on the variable display content, and the information for limiting the range of the random number value can be an upper limit value or a lower limit value of the random number. It should be a value.

Thus, the variable display mode can be grouped based on the information (upper limit or lower limit) indicating the limit of the random number, and the display information of the variable display content corresponding to the group is extracted for comparison. It is possible to sort the variable display modes in a very short time.

Further, the random number management updating means manages and updates the variable display mode determination random numbers by separate groups depending on whether a specific game state advantageous to the player is generated or not. it can.

Further, the management information extracting means generates a specific game state advantageous to the player;
When the information is not generated, the management information may be extracted from the corresponding group.

[0022] This makes it possible to sort the variable display mode into a case where a specific game state advantageous to the player is generated and a case where the specific game state is not generated. Can be done.

Further, a general prize area and a continuous prize area are provided in the variable prize apparatus 106, and the opening operation of the variable prize apparatus 106 is performed on condition that a game ball has won in the continuous prize area. Repeated up to the number of times.

The control of the progress of the game and the generation of random numbers used in the game control in the game board 100 are performed by the game control device 210 executing a series of programs.

More specifically, the main game program of the game microcomputer 211 is compactly configured so that its execution is completed within a certain interruption time (for example, 4 msec).

As shown in FIG. 5, the random number is generated by a random number updating process (P2) provided in the middle of the main game program, and a next interrupt signal (reset signal) provided at the end of the program. And the remaining time processing (P13) performed within the remaining time until. In addition, the extraction and determination of random numbers are performed in the special figure game process (P
4).

Since the game control device 200 has different control contents for each game board, it is common that when the game board 100 is replaced, it is replaced with a new one. Therefore, in general, the game control device 200 is configured to be attached to the back side of the game board 100 and to be exchangeable with the game board. However, it is not necessarily limited to such a configuration.

FIG. 2 shows the relationship between an example of the configuration of a game control device 200 for controlling the progress of a game and the generation of random numbers on the game board, and the input / output components.

As shown in FIG. 2, a game control device 200 is a one-chip microcomputer (a CPU in a broad sense) formed as a semiconductor integrated circuit for controlling an accessory required for a pachinko game or the like.
Microcomputer 211 comprising a clock generator 212 for obtaining a clock signal of a predetermined frequency by dividing the oscillation signal of the crystal oscillator, an input interface 213 for receiving signals from various sensors, and driving of solenoids and the like. And an output interface 214 for outputting a drive signal to the means and a control signal to another control device.

The above-mentioned gaming microcomputer 211
Is a central processing unit (CPU) as arithmetic control means
In addition, a ROM (read only memory) and a RAM (random access memory) as a storage means, an interrupt control circuit (not shown) and the like are built in, and are manufactured as an IC for a so-called amuse chip. The program and prize ball number data required for the game progress control performed by the CPU are RO
M.

Also, a game microcomputer 211
In the ROM, data of a fluctuation pattern for distributing a fluctuation display mode based on a random number value is stored in a table format.

The data of the variation pattern is shown in FIG.
As shown in FIG. 3, the pattern (a) in the case of the loss variation and the pattern (b) in the case of the big hit variation are stored separately.

In this embodiment, the "upper limit of random number" is used as information for limiting the range of the random value.

Each variation pattern is grouped by, for example, 1 to 50 distribution data. In the pattern (a) in the case of a loss variation, the random number upper limit value “600” corresponding to the distribution data “1”, “Specify fluctuation pattern 1” (that is, all special symbols are changed for 5.2 seconds) as the fluctuation display content, the random number upper limit value “200” corresponding to the distribution data “2”, and “variation pattern 1” as the fluctuation display content "Specify 2" (that is, all special symbols are fluctuated for 9.6 seconds) corresponds to the distribution data "3", and the upper limit of the random number is "100". All special symbols are changed for 10.0 seconds), the random number upper limit value is “10” corresponding to the distribution data “50”, and “variation pattern 5
Data such as "designate 0" (that is, all special symbols are changed for 40.0 seconds) is stored in the form of a table.

Similarly, in the pattern (b) in the case of the big hit change, the upper limit of the random number is “11” corresponding to the distribution data “1”, and “specify the change pattern 1” as the change display content (that is, all special patterns). The pattern is changed for 5.2 seconds), the random number upper limit value is “20” corresponding to the distribution data “2”, and “specify the change pattern 2” as the change display content (that is, all the special symbols are changed for 9.6 seconds). )
Random number upper limit value “30” corresponding to distribution data “3”,
“Specify fluctuation pattern 3” as the fluctuation display content (ie,
All special symbols are changed for 10.0 seconds), and the random number upper limit value “100” corresponding to the distribution data “50”,
Data such as "designate the variation pattern 50" (that is, all special symbols are varied for 40.0 seconds) is stored in the form of a table as the variation display content.

Then, the random number for change display at the time of jackpot, the random number for change display at the time of loss, the updated value of the distribution data for the big hit, and the updated value of the distribution data for the lost, which are managed and updated in the random number update process described later, The data is written in a predetermined area in the RAM of the computer 211.

Thus, for example, in the case of loss variation, if the distribution data “1” is acquired from the predetermined area of the RAM, the random number value (+1 increment) updated (+1 increment) every 4 msec reset interrupt 60
Until “0” is reached, display control information corresponding to “variation pattern 1” is transmitted to the variation display device 400. Further, in the case of the next loss variation, if the distribution data “2” is obtained from the predetermined area of the RAM, 4 m
Updated every second reset interrupt (+1 increment)
Until the random number value reaches “200”, the display control information corresponding to “fluctuation pattern 2” is
Send to

On the other hand, for example, in the case of a big hit variation, if the distribution data "1" is obtained from a predetermined area of the RAM, the random number value (+1 increment) updated (+1 increment) at every 4 ms reset interrupt is set to "11". , The display control information corresponding to “variation pattern 1” is transmitted to the variation display device 400. Further, in the case of the next big hit variation, if the distribution data “2” is obtained from the predetermined area of the RAM, the random number value (+1 increment) updated every 4 msec reset interrupt becomes “20”. Until it reaches, the display control information corresponding to “fluctuation pattern 2” is transmitted to the fluctuation display device 400.

As described above, the variable display patterns are grouped in advance according to the upper limit of the random number, and are kept until the updated (+1 incremented) random number reaches the upper limit of the random number specified based on the distribution data. The variable display mode can be sorted by the method of performing the variable display according to the group variable display pattern, and it is not necessary to compare the random number value and the determination value at the time of determination as in the conventional case, so that the time required for processing is reduced. can do. Therefore, even if the number of variable display patterns is increased, other processes are not squeezed too much, and the effect patterns can be further diversified to enhance interest.

Note that the gaming microcomputer 211

FIG. 3 shows a special symbol display 102 such as a liquid crystal display device provided on the game board and a display control for driving and controlling the special symbol display 102 based on a data signal from the game control device 200. A configuration example of a special symbol display device 400 as a variable display device including the device 420 is shown.

The display control device 420 includes a control microcomputer (CPU) 421, an interface circuit 422 with the game control device 200, a read only memory (ROM) 423 for storing control programs and fixed data,
A random access memory (RAM) 424 that provides a work area for the control CPU 421 and stores data and display data sent from the game control device 200, and an image display controller (V) that drives and displays the special symbol display 102.

Is done.

Control CPU 421 of display control device 420
, Display fluctuation time data and stop symbol data from the game control device 200 via the interface 422,
Display control information such as a stop command is input. When display control information is input from the game control device 200, a reception interrupt is applied to the control CPU 421 from the interface 422, and the control CPU 421 stores the received data (display control information) in the buffer area of the RAM 424 in response thereto. I do.

Then, the control CPU 421 analyzes the received data and, for example, effects patterns to be fluctuated and displayed based on fluctuating time data (a group of continuous display design data).
Is determined, a code indicating a symbol to be displayed, a display position, a command such as scrolling, etc. are generated and stored in the RAM 424. The effect patterns are stored in the ROM 423 in advance in the form of a table corresponding to the fluctuation time data.

This effect pattern corresponds to the above-described variation pattern. For example, if the variation pattern is “1”, “all special symbols are varied for 5.2 seconds”
If the variation pattern is “2”, the variation display according to the distribution process of the variation display mode is performed such that “all the special symbols are varied for 9.6 seconds”.

The image display controller 425 stores a data group corresponding to the above-described effect pattern transferred from the RAM 424 by the DMA controller 428 into the internal RA.
Read and expand to M. More specifically, character font data stored in the font ROM 426 is read in accordance with a code indicating a design, and image data to be displayed is associated with a display screen in accordance with display position data and a command. Store in the storage area. At this time, a background symbol for enhancing the effect is also generated in addition to a variable symbol for a special figure game such as a number, and stored in the display image storage area. The variable design and the background design may be stored after being combined, but may be combined when separately stored and read.

After that, the image display controller 425
The display image data is read from the display image storage area of the built-in RAM and sequentially sent to the γ correction circuit 427 to form a display drive signal of the special symbol display 102. At this time, scrolling for variable display is performed by the image display controller 425 according to parameters such as a command and a scroll speed.
Is performed by changing the start position of the image data to be displayed by the address calculation. Further, the image display controller 425 sends a vertical synchronization signal V-SYNC and a horizontal synchronization signal H-SYNC to the special symbol display 102. The γ correction circuit 427 adjusts the display illuminance of the display device by correcting the non-linear characteristic of the illuminance with respect to the signal voltage of the display device.
As a result, a predetermined display is performed on the screen of the special symbol display 102.

Next, with reference to FIG. 5, the main processing of the game program executed by the game microcomputer 211 of the game control device 200 will be briefly described.

FIG. 5 is a flowchart showing an example of the procedure of the processing of the game program executed by the reset interrupt.

The microcomputer 211 for the game is 4 ms.
The game program is started each time a reset signal for each ec (for example, output by a predetermined timer (not shown)) is input.

In a general flow, processing P1 to P12 in a series of game programs are performed at a reset interval of 4
The processing is completed within msec, and the remaining time processing P13 is repeatedly performed within the remaining time until the next reset signal is input.

When the game program P is started, first, an input process P1 is executed. The input process P1 is a process for determining a signal input state of a predetermined detector (sensor) provided on the game board such as the winning sensors SS6 to SS10.

Next, a random number update process P2 is executed. This processing constitutes a random number management updating unit. The details of the processing will be described later.

The random number updating process P2 includes a process of adding "1" to the value of the internal counter for generating random numbers. There are various kinds of random numbers for gaming, such as a random number for jackpot determination and a random number for determining a lost symbol, and all of these random numbers are updated in this process.

Subsequently, the state of the input signal from various switches (detectors) provided on the game board is read, and for example, the state changes from low level to high level and the high level becomes 2
If the number of times has been consecutive, a switch monitoring process P3 for determining that there is a detection signal and setting an input flag is performed, and the process proceeds to a special figure game process P4. The special figure game process P4 is a process of starting the variable display on the special symbol display 102 and stopping the variable display at a stop symbol determined based on the random number after a predetermined time has passed. Note that the special figure game process P4
In a subroutine in the figure, a fluctuation pattern determination process for acquiring distribution data is performed. The details of the processing will be described later.

Next, the process proceeds to the general figure game process P5, in which a flag for controlling the variable display on the normal symbol display device 122 is set, and the sound effect to the sound control device is adjusted in accordance with the display state of the general figure. A generation command and a command for giving a decoration display command to the decoration control device are set, and processing such as effect display at the time of starting a normal drawing is performed. Then, in the next process P6, a general map change process P6 for setting data for displaying the general map in the output area based on the information set in the process P5 is performed, and then the process proceeds to the fraud monitoring process P7. I do.

In the fraud monitoring process P7, a fraud monitoring process for judging the presence or absence of fraud on the game control device 200 is performed based on signals from the gold frame opening switch 302, the prize ball detection sensor 304, and the like and the internal control state.

Next, based on the processing state (game state) in the special figure game processing P4 and the general figure game processing P5, a special figure starting winning port made up of a solenoid for opening the variable winning device 106 and an ordinary electric accessory. A solenoid editing process (P8) for setting ON / OFF data in an output area for outputting a signal for controlling a solenoid for opening 103 to a corresponding output port is performed. Subsequently, an external information editing process (P9) for setting data for transmitting a jackpot signal, a special map change signal, and the like to the management device based on the processing state in the special map game process is performed.

Thereafter, a prize ball discharge command for the discharge control device 220, a prize storage display and various lamp drive commands for the decoration control device 240, and a sound control device 250 set in the input determination processing and the special figure game processing routine.
A series of command editing processes P10 for rearranging the sound generation commands for the order of transmission are performed.

Next, a series of command transmission processes P11 for rearranging the commands edited in the command editing process P10 and setting the commands in the output area are performed. continue,
The output data set in the output area in the command transmission process P11 is set to an output port, and an output process P12 for outputting a signal is executed. Then, the process proceeds to the remaining time process P13.

The remaining time process P13 is a process for generating a random number. After the processes P1 to P12 are completed,
It is repeatedly executed using the remaining time until the next reset signal is input, and generates a random number having a sufficient variation.

Next, a specific example of the random number update processing P2 will be described.
This will be described with reference to the flowchart of FIG.

This random number updating process constitutes a random number management updating means. First, in step S 1, a random number value for a fluctuation display at the time of a big hit and a random number value for a fluctuation display at a loss are obtained.
The random number value for fluctuation display at the time of big hit and the random number value for fluctuation display at the time of loss are
Although it is obtained from a predetermined area of the AM, data is not yet stored in the first processing after the start of the gaming machine, so "0" is obtained as an initial value.

Next, the process proceeds to step S2, in which the random number value for the variation display at the time of the big hit and the random number value for the variation display at the time of the loss are added to
After incrementing the random number by one increment, step S
Move to 3.

In step S3, distribution data values for the big hit and the loss are obtained. The distribution data for the big hit and the loss is obtained from a predetermined area of the RAM in the gaming microcomputer 211, but since the data is not yet stored in the first processing after the start of the gaming machine, it is set as an initial value. The distribution data “1” is acquired.

Next, in step S4, a random number upper limit value corresponding to the distribution data is obtained, and in step S5
Move to That is, if the loss distribution data acquired in step S3 is “1”, the random number upper limit value “6” is set.
00, if the distribution data is “2”, the upper limit of random number “200”, if the distribution data is “3”, the upper limit of random number “100”, and if the distribution data is “5”,
If it is "0", the random number upper limit value "10" is acquired. Similarly, if the distribution data for big hits acquired in step S3 is "1", the upper limit of random number is "11", and if the distribution data is "2", the upper limit of random number is "20". If the data is “3”, the upper limit of the random number “30” is set, and the distribution data is “5”.
If it is “0”, the random number upper limit value “100” is acquired.

At step S5, it is determined whether or not the random number value for large-hit-variation display has reached an upper limit value. That is, the random number value for fluctuation display at the time of jackpot updated in step S2 is compared with the upper limit value of the random number acquired in step S4, and when the random number value reaches the upper limit value, YES is determined and the process proceeds to step S6. If the upper limit has not been reached, the determination is NO, and the process proceeds to step S10.

In the step S6, the random number value (for example, "11", "20", etc.) for the display at the time of the big hit is set to "0" which is the initial value, and then the process proceeds to the step S7.

In step S7, the distribution data for the big hit is incremented by +1 and then the process proceeds to step S8 (for example, if the distribution data is "1", it is updated to "2").

In step S8, it is determined whether the distribution data is greater than the maximum value (for example, "50" in the example of FIG. 4B). If YES, the process proceeds to step S9. If NO, the process proceeds to step S9. Shifts to step S10.

In step S9, the big hit distribution data is set to the initial value "1", and then the process proceeds to step S10. In step S10, it is determined whether or not the random number value for loss variation display is the upper limit value (eg, "600" in the example of FIG. 4A). That is, the random value for variation display at losing time updated in step S2 is compared with the upper limit value of the random number acquired in step S4, and when the random number value reaches the upper limit value, YES is determined and the process proceeds to step S11. If the upper limit has not been reached, NO is determined and the routine proceeds to step S15.

In step S11, the random number value (for example, "600", "200", etc.) for loss variation display is set to "0" which is the initial value, and then the process proceeds to step S12.

In step S12, the allocating data for the loss is incremented by +1 and then the process proceeds to step S13 (for example, if the allocating data is "1", it is updated to "2").

In step S13, it is determined whether or not the distribution data is larger than the maximum value (for example, "50" in the example of FIG. 4A). If YES, the process proceeds to step S14, and if NO, the process proceeds to step S14. Shifts to step S15.

In step S14, the loss distribution data is set to "1" which is the initial value, and the flow advances to step S15.

In step S15, each value updated in the processing in steps S1 to S14 is stored in each predetermined storage area in the RAM of the gaming microcomputer 211, and the flow proceeds to the subsequent processing. As the processing performed after step S15, there are a random number update processing for a big hit determination, a random number update processing for a big hit symbol, and the like, but details thereof are omitted.

Next, a specific example of the fluctuation pattern determination processing performed in the subroutine in the special figure game processing P4 will be described with reference to the flowchart of FIG. This process is performed immediately after the start winning or when the start memory exists and immediately before the start of the change.

First, in step S100, it is determined whether or not the fluctuation result is a big hit. If the result is a big hit, the flow shifts to step S101 to acquire big hit distribution data, and then shifts to step S103. If it is not a big hit, the process proceeds to step S102 to acquire loss distribution data, and then proceeds to step S103.

In step S103, the obtained distribution data is assigned to a variation pattern number (for example, in the example of FIG. 4, “variation pattern 1” for distribution data “1”, and “variation pattern 2” for distribution data “2”). ) Etc., and then return to the main routine.

With the above processing, the distribution data is updated each time the random number value reaches the random number upper limit value, and the fluctuation display pattern changes from fluctuation pattern 1 to fluctuation as shown by the arrows in FIGS. 4 (a) and 4 (b). Pattern 2 → ・ ・ ・ → variation pattern 50
→ Variation pattern 1 →...

As described above, the variable display mode is distributed as follows.
This is performed by a method of extracting information (table data in FIGS. 4A and 4B) which is previously grouped and managed for each variable display mode, and is displayed using one random number as in the related art. The processing time can be reduced as compared with the case where the number of aspects and the corresponding determination values are compared one by one. That is, conventionally, for example, when there are 50 groups in the determination range of the random number, the comparison between the random number value and the determination value may be performed up to 50 times, but according to the method of this embodiment, In addition, the process of comparing the random number value with each determination value becomes unnecessary, and the time required for distributing the variable display modes can be reduced.

Therefore, even if a high-speed CPU is not used, it is possible to increase the number of variable display modes such as a losing variation symbol, a reach losing variation symbol, a large hit variation symbol, and the like, and to further diversify the effect, thereby increasing the interest. Can be increased.

In this embodiment, the maximum random number value is used as information for limiting the range of the random number value. However, the present invention is not limited to this. For example, a minimum random number value may be used. . In this case, the random number and the like are updated by decrementing by one in step S2 and the like in FIG.

Although the invention made by the present inventor has been specifically described based on the embodiment, the embodiment disclosed in this specification is an example in all respects and is limited to the disclosed technology. It should not be considered a thing. That is, the technical scope of the present invention should not be interpreted in a limited manner based on the description in the above embodiment, but should be interpreted in accordance with the description of the claims. It includes all modifications within the scope of the appended claims and equivalent technology.
