Here, with reference to the conceptual diagram of FIG. 5, the relationship between touch detection of the card 80-1 and code reading by the game apparatus 10-1 according to the embodiment of the present invention will be described in more detail.
Under the card 80-1 placed on the game apparatus 10-1, one of the touch electrodes 400-1 that are electrodes of the touch switch as described above is provided, and this electrode is provided to the sensor microcomputer 310-1. It is connected. In this state, an infrared image irradiated from behind the card can be captured by the infrared camera 260.
In other words, in game device 10-1 according to the embodiment of the present invention, the printed material can be read from the back of the touch switch. Ie:
. A card touch sensor and a code reader can be combined.
. Using the transparency of the touch switch, the code of the card 80-1 can be read from the back side using a reader such as a camera. The print target of the game medium such as the card 80-1 can be a card or a three-dimensional object.
Therefore, it is possible to achieve both the touch detection and the code reading.
At this time, not only combining the reading of the touch sensor and the infrared camera, but also supplementing the touch sensor information using the camera image as described later, thereby supplementing the pressed position of the touch sensor with higher accuracy. Can do.
Further, depending on the type of detection target (for example, a card) on which a code such as a game medium is printed, there are some that affect the capacitance. Therefore, it is possible to cope with this influence by detecting the type of the detection target with a code recognized from the infrared image and correcting the capacitance value.

[Configuration of Game Device 10-1]
Next, with reference to FIGS. 6 to 10, the internal configuration of game device 10-1 according to the embodiment of the present invention will be specifically described.
Referring to the cross-sectional view of FIG. 6, a play field 60 (a plane, a plane portion) is configured on the upper portion of the housing 70.

The play field 60 includes, for example, a protective layer 610, a play field sheet 620, a touch panel sheet 630, and a glass plate 640, and each is substantially transparent to infrared rays. As such, each is made up of members that are substantially transparent to infrared. Then, the cards 80-1 to 80-n are arranged on the protective layer 610.
Here, when infrared rays are radiated from the illumination unit 210 inside the housing 70, the codes of the cards 80-1 to 80-n (for example, the code 810-1 in FIG. 11) are passed through the first filter 711 that transmits almost only the infrared rays. Infrared rays hit the surface on which (˜810-n, etc.) is drawn. The infrared rays reflected from the cards 80-1 to 80-n are narrowed down through the first reflecting plate 721 and the second reflecting plate 722. Then, the narrowed infrared ray can be imaged by the infrared camera 260 through the second filter 712 that allows only the infrared ray to pass therethrough.

  Here, in the game device 10-1, for example, the touch electrodes 400-1 to 400-n (see FIGS. 8 and 9) printed on the touch panel sheet 630 make contact with the cards 80-1 to 80-n. Can be sensed.

Referring to FIG. 7, a schematic diagram of a plane drawn from a direction (upper surface) in which the user looks down in the vicinity of the play field 60 of the game apparatus 10-1. Thus, cards 80-1 to 80-n are arranged in the play field 60.
The relationship between the illumination unit 210, the first filter 711, the first reflecting plate 721, the second reflecting plate 722, the second filter 712, and the infrared camera 260 is arranged in a line as shown by the dotted line. Has been placed. With this configuration, the play field 60 can be widely used.
The display 270 can be installed above the second reflection plate 722 and on the housing 70.

(Configuration of play field 60)
Referring to the conceptual diagram of FIG. 8, there is shown a schematic diagram of the play field 60 of the game apparatus 10-1 according to the embodiment of the present invention.
As described above, cards 80-1 to 80-n are arranged on play field 60 in game device 10-1 according to the embodiment of the present invention. Then, through the first filter 711, the back surface of the play field 60 is irradiated mainly with infrared light from the light source of the illumination unit 210. At this time, the infrared light is irradiated to the back surfaces of the cards 80-1 to 80-n through the touch panel sheet 630 and the play field sheet 620 that substantially transmit infrared light. And the code | cord | chord can be recognized by reading the infrared-light reflected from the back surface of the cards 80-1 to 80-n.
In addition to this, in the game apparatus 10-1, the coordinates at which the user's finger touches can be recognized on the play field 60.

Here, the structure of the play field 60 will be described in more detail with reference to the cross-sectional view of FIG.
First, a glass plate 640 made of glass or the like that is transparent to invisible light such as infrared rays is provided from below (backward) where infrared light is irradiated.
A touch panel sheet 630 is provided above the glass plate 640. In the touch panel sheet 630, (i) a method of screen printing a conductive paste containing extremely fine conductive particles on a transparent substrate (see JP2007-142334 etc.), a printing method such as gravure printing, ( ii) A method of laminating a metal foil such as copper on a transparent substrate, forming a resist pattern on the metal foil, and etching the metal foil (see Japanese Patent Application Laid-Open No. 2008-32884 etc.), and a manufacturing method such as photolithography Thus, touch electrodes 400-1 to 400-n are formed, and conductive patterns corresponding to the respective electrodes are connected to sensor microcomputers 310-1 to 310-n (not shown).
Above the touch panel sheet 630, there is provided a play field sheet 620 through which infrared light is transmitted, although a schematic diagram of a field, etc., is printed as in the prior art.
A transparent protective layer 610 is further provided above the touch panel sheet 630.
Above the protective layer 610, cards 80-1 to 80-n are arranged by the user during the card game play. Here, an example in which the card 80-1 is arranged is shown. As shown in the figure, a code 810-1 that reflects infrared rays and is optically readable is printed on the back surface of the card 80-1.
The touch panel sheet 630 may be positioned above the play field sheet 620. Further, the play field sheet 620 or the touch panel sheet 630 may be formed integrally with the protective layer 610. Further, when a projector or the like is used as described later, another layer for projecting video (image) may be provided.

Next, with reference to a cross-sectional view of FIG. 10, the protective layer 610 includes a conical protrusion as shown in FIG. 10A, or a hemispherical protrusion as shown in FIG. Can be provided. Such protrusions reduce friction and allow the cards 80-1 to 80-1 to 80-n to move smoothly and play. Further, wear of the protective layer 610 can be suppressed. Furthermore, since infrared light is diffused by the protrusions, erroneous recognition of the codes 810-1 to 810-n due to scratches on the protective layer 610 can be reduced.
Referring to FIG. 10A, the end portion 611 of the cone is formed to be flat rather than a complete protrusion, so that both pressure distribution to the card and smooth movement can be achieved. Further, the diameters of the conical trunk portion 612 and the end portion 611 can be formed such that moire patterns are not easily generated when the codes 810-1 to 810-n are recognized.
By forming the hemispherical portion 613 of FIG. 10B in a hemispherical shape, the stimulation to the user's hand can be further reduced. Moreover, the effect that it is easy to remove dirt at the time of wiping off is also acquired. The diameter of the hemisphere can also be formed so as not to cause a moire pattern.

(Configuration of code 810-1)
Next, a schematic diagram of the code 810-1 on the back surface of the card 80-1 will be described with reference to FIG.
The cord 810-1 has a structure in which several circumferential bands extend from the central axis 820, where lightness is high (white) and lightness is low (black) due to infrared reflection. Can be distinguished. Various information can be described by this black and white pattern. Further, by arranging them in a circumferential shape, it is possible to accurately recognize and grasp the position (coordinates) and orientation (angle) of the card on the play field 60 and the boundary between the card and other locations. is there. As a result, not only can the touch panel and the code be read simultaneously, but the position of the touch panel 400-1 to 400-n on the touch panel can be accurately grasped even if the number of touch electrodes 400-1 to 400-n is reduced. As a result, it is possible to reduce the cost of the calculation devices for creating and recognizing the touch electrodes 400-1 to 400-n.

  In addition, as the black and white pattern, for example, by describing information using a gray code, it is possible to suppress the influence of erroneous recognition.

  In addition, the information amount to the game medium can be increased by describing information using not only a black and white pattern but also, for example, coordinate information based on a predetermined pattern or a dot pattern meaning a code. Note that the pattern can have a plurality of values depending on the reflection frequency of invisible light such as infrared rays.

As information described in the code 810-1, information indicating the type of card and the like is described as described above. The type of card includes information on a special “kira card” described later. In addition, it also describes information about which position of the card is contacted and whether or not a “special attack” or the like on the play as described later can be performed.
Further, the information described in the code 810-1 includes an ID for distinguishing the same type of card by a serial number or the like.

[Play processing of game device 10-1]
Here, referring to the flowchart of FIG. 12, the player P who is the user of the game apparatus 10-1 of FIG. 2 uses the game apparatus 10-1 to play a card game specifically on the game apparatus 10-1. The flow when doing this will be described.
In the play process, a control unit such as the CPU 100 mainly executes a specific process using hardware resources such as the program 111 and the data 112 stored in the storage unit 110.

(Step S101)
First, the CPU 100 performs a play start process.
Here, first, the CPU 100 detects whether or not the IC card 85 is inserted using the IC card reader / writer unit 220 via the peripheral I / F 140.
Then, the CPU 100 detects through the peripheral I / F 140 that a payment has been made by inserting a coin using the coin inserting unit 250 or using a prepaid card.
When CPU 100 detects that payment has been made, CPU 100 advances the process to step S103.
In other cases, the CPU 100 displays a screen instructing insertion of coins or a prepaid card on the display 270 or outputs audio from the audio processor 180 to the speaker 280.
Further, when payment is made without the IC card 85 being inserted, the CPU 100 prompts the user to insert the IC card 85 and notifies that the starter pack of the IC card 85 needs to be purchased.
In a state where the IC card 85 is not inserted and payment is not performed, the CPU 100 can display a demonstration screen on the display 270 to attract the interest of the player. At this time, the CPU 100 can make the player know that the game apparatus 10-1 is not played by not outputting the sound.

(Step S102)
Next, the CPU 100 performs an IC card reading process.
The CPU 100 reads the data of the IC card 85 using the IC card reader / writer unit 220 via the peripheral I / F 140.
As described above, the IC card 85 is a contact type or non-contact type IC card, and includes a flash memory (storage unit), an MPU (control unit), and the like, and encrypts and stores data relating to the game. be able to.
As data relating to this game, as will be described later, data such as the level of each character of each card 80-1 to 80-n, military funds in the game, territories controlled, ranking, etc. can be stored. .
Further, as the data relating to this game, the play level of the player P and the like are also stored. The level of this play includes game-related information related to the game, such as the scenario number in progress of the “campaign mode”, the number of territories in control, and whether the player P has played multiple game scenarios, It is possible to store player-related information related to the player, such as how many pieces of powerful ability value data are possessed among the cards 80-1 to 80-n and the winning percentage of play in the card game.
As will be described later, the CPU 100 can change selectable scenarios according to the level of play.

If reading of the stored data from the IC card fails or illegal data is stored, the CPU 100 can end the play process without proceeding to the next step S103. .
At this time, the CPU 100 transmits data of “IC card failure / illegal” to the server 5. In addition, the CPU 100 can instruct the speaker 280 to sound a siren or the like from the audio processor 180 and prompt a call to a clerk (staff) of the amusement facility. The CPU 100 can also pay back coins from the coin insertion unit 250.

(Step S103)
Here, the CPU 100 performs a game process that specifically executes the game.
In this game process, the CPU 100 executes a part of the program 111 in the storage unit 110 that performs a specific process on the game.
Hereinafter, an example will be described in which the game device 10-1 according to the embodiment of the present invention executes a tactical class real-time simulation game (real-time strategy) that deals with battles of the Sangokushi-style era.
As a flow of this real-time simulation game, first, the CPU 100 reads out a game scenario according to a user's selection of a game mode or the like.
On this basis, regarding the enemy unit (enemy character) and neutral unit (neutral character) in the scenario, the CPU 100 gives an instruction using AI (artificial intelligence), or the opponent gives an instruction via the network.
For the teammates (play character, game character) on the scenario, the player P places cards 80-1 to 80-n, selects (contacts) the cards 80-1 to 80-n, and switches 240 An instruction is given by selecting a command or the like.
Instructions to these enemy units, neutral units, and friendly units are calculated by the CPU 100 in units of “frames” every 1/60 seconds, for example, and reflected in the progress of the game in real time. As a result, the CPU 100 increases or decreases the personnel of the unit, or causes a change that the position on the map belongs to a friendly unit or an enemy unit.
Further, the CPU 100 causes the graphic processor 160 to draw this change on the display 270. Further, the CPU 100 causes the speaker 280 to output sound effects and BGM (background music) using the audio processor 180.
When scenario termination conditions such as unit personnel, placement, and position affiliation are satisfied, or a predetermined time elapses, the CPU 100 ends the game process.

The game system X is a so-called multi-platform, and the game apparatus 10-1 can select and play a plurality of types of games. At this time, the type of game that can be played is described on the IC card 85, and the program 111 itself is downloaded from the server 5 and executed according to the selection of the player P.
Further, when the player P is playing a game, the play content can be displayed on the large display device 55 via the server 5 of FIG. 1 to enjoy a more powerful play.
Hereinafter, the game process will be described in detail with reference to FIG.

(Step S301)
First, the CPU 100 performs a scenario reading process.
First, prior to the selection of this scenario, the player P in FIG. 2 selects a game mode using the buttons and switches 240 of the software keyboard drawn on the play field 60.
As this game mode, “campaign mode” that wins the prepared scenarios in order, “national conquest mode” that selects a scenario for each country by selecting “country” to attack, player P and other game devices “Matching mode” in which a scenario is selected between 10-2 to 10-n to play a match, “Scenario selection mode” in which a scenario that has finished (cleared) the scenario can be selected, and a game play method for beginners Modes such as “Tutorial” can be selected.
When detecting that the player P has selected the game mode, the CPU 100 reads a scenario corresponding to each game mode in accordance with the instruction of the player P.
This scenario may be stored as a part of the data 112 in the HDD of the storage unit 110 or may be configured to be downloaded from the server 5.

As the contents of the scenario data, map data, unit arrangement data, end condition data, special weapon data, and the like can be used.
The map data is 3D data (virtual three-dimensional space information) of the map that becomes the battlefield, and performs projection conversion, viewpoint change, shading (shaded) processing, etc. in real time using the graphic processor 160, the display 270, It is displayed on the large display device 55 from the server 5 via the network. The map data includes data such as height and terrain attributes, and it is possible to specify terrain data such as swamps and pits related to the advancing speed of the unit, steep slopes where the unit cannot proceed, and the like. In addition, on the map data, “base” data is stored that can be controlled by enemy units and allies moving to the coordinates and taking the “flag”. In addition, objects such as castles, stone walls and moats can be arranged in each base.
The unit arrangement data can be stored by arranging enemy units and allied units on the map data, and determining the reinforcement timing, scenario end conditions, and the like.
In addition to the annihilation of enemy units or allied units, the end condition data includes various conditions such as controlling a predetermined base, defeating a leader of a specific unit, or invoking a predetermined “deadly move”. Can be stored.
When the scenario reading process ends, the CPU 100 starts a process related to a specific game play.

(Step S302)
CPU100 performs the card | curd detection process which detects the arrangement | positioning and contact state of card | curd 80-1 to 80-n.
As described above, this process is to detect an instruction for the player P in FIG. 2 to give to the team, and unlike the prior art, in the game apparatus 10-1 according to the embodiment of the present invention, the card Various instructions that can improve game performance can be detected by using the arrangement state of 80-1 to 80-n and the contact state instead of a simple combination.
First, referring to FIG. 14 to FIG. 20, for each of the cards 80-1 to 80-n, specifically, how to read the codes 810-1 to 810-n using infrared rays or the like Whether to detect and specify the touch position from the touch of the touch electrodes 400-1 to 400-n will be described in detail.
With regard to this card detection process, (1) a process for detecting cards 80-1 to 80-n using ordinary paper media, and (2) a special “kira card” (capacitance that is contained in metal foil or the like) The description will be divided into processing for detecting cards 80-1 to 80-n including game media having different values.
Whether to select the processing (1) or (2) can be selected by the CPU 100 by storing it in the nonvolatile memory of the storage unit 110 according to the type of the card game.

[(1) Detection of Cards 80-1 to 80-n Using Normal Paper Medium]
First, detection of the cards 80-1 to 80-n using a normal paper medium will be described with further reference to FIGS.
As described above, the touch electrodes 400-1 to 400-n, which are capacitance electrodes formed on the touch panel sheet 630 by printing or the like, are connected to the sensor microcomputers 310-1 to 310-n by wiring (see FIG. 4, see FIG.
Therefore, “multi-touch”, that is, it is possible to acquire a plurality of pieces of information that contact each electrode at the same time.
Further, by using the processing of the image acquired by the infrared camera 260, it is possible to detect the position of the card and the contact position with higher accuracy.
In the following, with reference to the flowchart of FIG. 14, the detection of the contact position and the detection of the code are more specifically exemplified by processing among the CPU 100, the touch electrode 400-1, and the sensor microcomputer 310-1. Explained.

(Step S1021)
First, the CPU 100 of the game apparatus 10-1 performs sensor microcomputer operation start processing.
Here, at the start of the game process of FIG. 12, the CPU 100 controls the electronic switch from the peripheral I / F 140 to supply power to the sensor microcomputers 310-1 to 310-n.
Thereby, the sensor microcomputers 310-1 to 310-n can be operated only during the game process, and an effect that the operating cost of the game apparatus 10-1 can be reduced is obtained.

(Step S1022)
Next, the CPU 100 performs a sensor microcomputer communication connection process.
In this process, the CPU 100 checks whether communication connection is possible between the sensor microcomputers 310-1 to 310-n and the CPU 100 via the peripheral I / F 140.
If any of the sensor microcomputers 310-1 to 310-n does not respond as a result of this check, the CPU 100 transmits a failure to the server 5 via the communication I / F 200 as a failure. Further, a siren or the like is sounded to notify the administrator of the game apparatus 10-1.
If all the sensor microcomputers 310-1 to 310-n have responded, the CPU 100 advances the process to step S1023.

(Step S1023)
Next, the CPU 100 performs sensor microcomputer initialization processing.
In this example, an initial signal or the like is transmitted to the sensor microcomputers 310-1 to 310-n. Thereby, each of the sensor microcomputers 310-1 to 310-n starts the initialization process from the first position of the built-in ROM or the like.
As this initialization process, each sensor microcomputer 310-1 to 310-n performs processes such as connection confirmation and calibration for the connected touch electrodes 400-1 to 400-n.
Then, each of the sensor microcomputers 310-1 to 310-n transmits log data as a result of the initialization process to the CPU 100. In addition, when abnormality is recognized in log data, CPU100 can also transmit to the server 5 via communication I / F200, and can notify the administrator of the game device 10-1 by sounding a siren or the like.
Thereafter, when the initialization process is normal, each of the sensor microcomputers 310-1 to 310-n waits for a detection start signal from the CPU 100.
Hereinafter, the sensor microcomputer 310-1 will be described as a representative example of detection of card contact among the sensor microcomputers 310-1 to 310-n after the card game is started.

(Step S1024)
Here, the sensor microcomputer 310-1 determines whether a detection start signal is received from the CPU 100.
This detection start signal is transmitted by the CPU 100 after the card game is started. By this detection start signal, as described above, the sensor microcomputers 310-1 to 310-n can detect the contact of the cards 80-1 to 80-n at about 60 times / second.
If the determination in step S1024 is Yes, the sensor microcomputer 310-1 advances the process to step S1030.
Conversely, if the determination in step S1024 is No, the sensor microcomputer 310-1 returns the process to step S1024.

(Step S1025)
Next, the sensor microcomputer 310-1 performs a scanning process.
Specifically, the capacitance is sequentially measured from each electrode of the touch electrode 400-1 that is scanned by the sensor microcomputer 310-1, and subjected to A / D conversion or the like to obtain a capacitance value (touch count value). Get.
With this capacitance value, it is possible to obtain values for whether each electrode is turned on / off and for the pressure (contact area) of touch contact.
When the capacitance values of all the electrodes of the touch electrode 400-1 are obtained, the sensor microcomputer 310-1 writes the capacitance values in the storage unit 110 by DMA transfer or the like via the communication I / F 200. Further, the CPU 100 can directly acquire the capacitance value and store it in the storage unit 110. Thereby, the scanning process is terminated.

(Step S1026)
Next, the CPU 100 performs an electrode coordinate acquisition process.
Here, CPU100 acquires the coordinate of the electrode which is touched (pressed) by the user from the capacitance value acquired from each sensor microcomputer 310-1 to 310-n.
Here, the relationship between the size of each electrode and the coordinate acquisition of the pressed electrode (in contact) will be described in detail with reference to FIGS.

[Relationship between electrode size and electrode coordinate acquisition]
First, referring to the conceptual diagram of FIG. 15, for example, if the area of each capacitive electrode of the touch electrode 400-1 is too large for the card 80-1 that is a detection target, The judgment becomes ambiguous. For this reason, the maximum area of an electrode is determined on the basis of the area of the card 80-1 as a detection target.
In addition, when using the cards 80-1 to 80-n, the position where the card is pressed (the position where the card is touched) is detected only in a predetermined area from the center of each card, thereby reducing erroneous detection. it can.
Of these entire cards 80-1 to 80-n, an area where specific detection is performed is set as an effective area.
When the inventor of the present invention repeated diligent experimentation and research for use in a specific game, there is an area of about 70% of the effective area with respect to the area of the card 80-1 that is the assumed detection target. In other words, it was found that the position of the card 80-1 can be specified at high speed with high accuracy in combination with subsequent recognition of the infrared image. That is, the size of one electrode of the touch electrode 400-1 can be about 70% of the size of the card 80-1.
Even when a figure or the like is used as a game medium instead of the card 80-1, for example, the area of the effective area such as 70% with respect to the area of the grounding surface on which an optical code such as a two-dimensional code is printed. Can be used.

Here, referring to FIG. 16, the size of one electrode is set using an effective area necessary and sufficient for detecting each of cards 80-1 to 80-n from detection target card 80-1. The electrode area determining method to be determined will be described in more detail.
First, when the external dimensions of the card 80-1 are length A × length B, and the area of the effective area is M (%) with respect to the entire card 80-1,

a = K x A
b = K x B
(M = K ² × 100) …… Formula (1)

It becomes.

Here, a region per place of the touch electrode 400-1 is defined as length c × length d.
A method of obtaining the length c and the length d will be described with reference to FIGS. 17A and 17B.
First, referring to FIG. 17A, a positional relationship in which the sensor just straddles adjacent cards that are in close contact with each other is a “worst condition” in which it is difficult to detect the position of contact. That is, when determining whether the electrode is “ON” from the capacitance value of the touch electrode 400-1, it is not possible to determine which of the card 80-1 and the card 80-2 is in contact.
For this reason, in order to specify the card being touched, it is necessary to keep the size per electrode within the “dead zone” that is an area outside the effective area.

Referring to FIG. 17B, as described above, when the M (%) of the card area is the touch effective area, the lateral width c of the touch sensor is

c = A−a = A−K × A (2)

It becomes. This can be one lateral width of the electrode of the touch electrode 400-1.
Similarly, the vertical width d is

d = B−K × B (Formula 3)

As can be set.
At this time, when the rotational orientation of the card is also taken into consideration, the area of the touch sensor can be set to a size in which the shorter one of the horizontal width c and the vertical width d is a diagonal line.
As described above, when the inventors of the present invention conducted intensive experiments and researches, in the case where the electrodes of the touch electrodes 400-1 to 400-n are arranged with the maximum cost performance, 70 in the area to be detected. One suitable example is that the effective region is about%.
That is, touch electrodes (switches) can be installed to the minimum necessary for one of the cards 80-1 to 80-n. Therefore, when the effective area is set to 70% in this way, it is possible to detect the coordinates at which the cards 80-1 to 80-n are touched at a reduced cost.

Here, referring to FIG. 18, as another example, the sizes of the touch electrodes 400-1 to 400-n are obtained based on an area obtained by equally dividing the area of the detection target card 80-1. Is also possible.
When the inventors of the present invention repeated diligent experiments and tests, it is preferable to use an area of 1/6 or 1/9 of the cards 80-1 to 80-n as the equally divided area. I found it.
As shown in FIG. 18, in the case of an area of 1/6, the size obtained by dividing the card area into 6 equal parts is the size of one electrode of the electrode 400-1.
In the case of an area of 1/9, the size obtained by dividing the card area into nine equals is the size of one electrode of the electrode 400-1.
If it sets in this way, it will also become easy to grasp | ascertain which position in card | curd 80-1-80-n contacted.

In summary, for each of the touch electrodes 400-1 to 400-n, it is preferable to arrange the electrodes so as to cover 70% of the cards 80-1 to 80-n.
Alternatively, it is preferable that the contact positions of the cards 80-1 to 80-n are detected in detail so that the area of the cards 80-1 to 80-n is 1/6 or 1/9. It is.

(Step S1027)
Here, with reference to FIG. 14 again, (1) processing for detecting the cards 80-1 to 80-n using ordinary paper media will be described.
In step S1027, the CPU 100 performs infrared image card position acquisition processing.
In this process, similarly to the prior art 1, as shown in FIG. 6, infrared images or the like are used to receive images printed on the back surfaces of the cards 80-1 to 80-n using the infrared camera 260.
Then, the CPU 100 analyzes the received image using the graphic processor 160 and the like, and recognizes codes 810-1 to 810-n as shown in FIG.
Thereby, the value of the operation information about the coordinates (position), angle (direction), ID (card type), etc. on the play field 60 of the cards 80-1 to 80-n can be obtained.
The CPU 100 stores values of operation information such as coordinates, angles, and IDs of the respective cards 80-1 to 80-n in the storage unit 110.
When the cards 80-1 to 80-n are not placed on the play field 60, a flag “not placed” is stored. Further, the coordinates may be values indicating the outside of the screen, for example, (X, Y) = (− 1, −1).

(Step S1028)
Next, the CPU 100 performs card information acquisition processing.
As this card information,
-Position where the user touches on the play field 60 (contact information)
-Acquire information such as the number of cards 80-1 to 80-n on the play field 60, ID, coordinates, angle, and touch information.

Here, the above-mentioned “touch information” will be described.
CPU100 acquires the information regarding a touch, ie, contact, with the cards 80-1 to 80-n on the play field 60, and acquires touch information. As this touch information, it is possible to use information such as a flag indicating whether the card is touched, the strength being touched, and the coordinates being touched.
Of the touch information, the coordinates being touched are corrected based on the image processing of the card.
Specifically, the coordinates of the electrodes 80-1 to 80-n acquired by the above-described infrared image card position acquisition process are corrected by the coordinates of the contacted electrode acquired by the electrode coordinate acquisition process.
For example, when the cards 80-1 to 80-n and the coordinates of the electrodes overlap, the CPU 100 sets the position in the card as the contacted coordinates. Further, when a certain electrode is in contact with the CPU 100 but is separated from the cards 80-1 to 80-n within a predetermined value, the CPU 100 sets the coordinates of the cards 80-1 to 80-n to be in contact with each other. To do. Further, the CPU 100 is contacted with the coordinates of the electrodes closer to the cards 80-1 to 80-n when the capacitance value of the contact of the two to four electrodes indicates a close value. Coordinates.
Also, temporal correction is possible. As described above, the touched coordinates can be updated in 1/60 seconds, for example. Therefore, when the contacted electrode moves, the CPU 100 selects which card 80-1 to 80-n is touched based on the amount of movement, and the selected card 80-1. The coordinates of ˜80-n are the touched coordinates.
Thus, when the cards 80-1 to 80-n are in contact, the CPU 100 can store the corrected coordinates in the touch information. In addition, the touched information in the card can also be stored in the touch information.

(Step S1029)
Here, the description returns to the operation of the sensor microcomputer 310-1.
The sensor microcomputer 310-1 determines whether the detection of the contact with the card has been completed.
Specifically, the sensor microcomputer 310-1 determines whether a detection end signal has been received from the CPU 100. Note that the CPU 100 can transmit this detection end signal at the end of the game process in step S103 of FIG.
If the determination in step S1029 is Yes, the sensor microcomputer 310-1 advances the process to step S1030.
Conversely, if the determination in step S1029 is No, the sensor microcomputer 310-1 returns the process to step S1024, and repeats the process below the scan process, for example, every 1/60 seconds.

(Step S1030)
Next, when the detection is completed, the CPU 100 performs a sensor microcomputer operation stop process.
Specifically, when the detection end signal is received, the sensor microcomputer 310-1 enters a mode in which the operation such as the HALT state is stopped to reduce power consumption.
In addition, the CPU 100 controls the electronic switch from the peripheral I / F 140 to turn off the sensor microcomputers 310-1 to 310-n.
Thereby, power consumption can be suppressed while the game is not being played, and malfunctions can be reduced.
Thus, (1) the processing for detecting the cards 80-1 to 80-n using ordinary paper media is completed.

[(2) Processing for detecting cards 80-1 to 80-n including special “kira cards” such as metal foil]
Next, processing for detecting the cards 80-1 to 80-n including the “kira card” will be described.
“Kira Card” is a card with metal foil etc. scattered on the surface or inside like “Lame” or foil printed on aluminum layer etc. As a card with special value in card games Often used.
In other words, this “kira card” has a low resistance due to the use of a metal foil, and bridges between straddling electrodes to detect the capacitance between both electrodes, and as a result is detected. The capacitance increases.

For this reason, it can be considered that the coordinates of the cards 80-1 to 80-n are obtained on the play field 60, and the capacitance value is corrected accordingly.
Specifically, an “offset value” corresponding to each electrode is obtained, and the CPU 100 stores the “offset value” in the storage unit 110, corrects the obtained capacitance value, and replaces the “kira card” with a normal card. Similarly, it can be detected.
Hereinafter, with reference to the flowchart of FIG. 19, (2) processing for detecting cards 80-1 to 80-n including special “kira cards” such as metal foil will be described in more detail.

(Steps S1031 to S1034)
Referring to FIGS. 19 and 14, in these processes, step S1031 performs the same process as step S1021, step S1032 performs step S1022, step S1033 performs step S1023, and step S1034 performs the same process as step S1024.

(Step S1035)
Here, the CPU 100 performs infrared image card position acquisition processing. This process is also the same as step S1027 in FIG.
As a result, first, the values of the coordinates (position), angle (orientation), ID (card type), etc. on the play field 60 of the codes 810-1 to 810-n on the back of the cards 80-1 to 80-n are obtained. Thus, in the subsequent processing, it is possible to determine whether the card is a Kira card based on the ID and perform correction processing.

(Step S1036)
Next, the CPU 100 determines whether there is a glitter card.
Here, it is determined whether or not there is a glitter card among the cards 80-1 to 80-n on the play field 60 in FIG.
If the determination in step S1036 is Yes, the CPU 100 advances the process to step S1037.
Conversely, if the determination in step S1036 is No, the CPU 100 advances the process to step S1039 and performs normal scan processing.

(Step S1037)
The CPU 100 performs a kill card area calculation process.
Referring to the conceptual diagram of FIG. 20, as described above, when the killer card is in contact with the electrode, the killer card and the electrode are connected to the switch of each electrode of the touch electrodes 400-1 to 400-n. The capacitance value increases by a value proportional to the overlapping area.
That is, as shown in FIG. 20, when a killer card is arranged across a plurality of touch electrodes at an arbitrary position on the field, the touch electrodes 400-1 to 400-n malfunction.
In other words, the cause of the malfunction of the touch electrodes 400-1 to 400-n is that the touch switch calculates the sensitivity value from the relationship of the capacitance with the object on the electrode, and therefore when the killer card is placed. This is because the sensitivity value changes in proportion to the area covering the electrode.
Therefore, in game device 10-1 according to the embodiment of the present invention, the card position is specified by recognizing codes 810-1 to 810-n. That is, by identifying the codes 810-1 to 810-n by image recognition with the game device 10-1, the position coordinates of the specified card can be used. Thereby, it is possible to calculate the area covering each electrode by combining the position coordinate information and electrode position information of the specified card.
That is, by using the calculated area and subtracting the increment of the sensitivity value in advance to perform the touch calculation, malfunction of the electrodes 400-1 to 400-n can be suppressed.

In the example of FIG. 20, when the card 80-3 is a Kira card, the overlapping area is calculated for each electrode overlapping the card 80-3. Since the position of the electrode is known in the play field 60, the known coordinate is stored in the storage unit 110, and the intersection of the card and the electrode is calculated to calculate the area of the overlapped portion. Can do.
For example, in the example of FIG. 20, since the electrodes of the touch electrode 400-1 do not overlap, calculation is not performed. On the other hand, since the electrodes of the touch electrode 400-9 are overlapped, the area of the overlapped portion can be calculated.
CPU100 memorize | stores the value of the area of the overlapped part calculated | required about each electrode in the memory | storage part 110 as an array variable etc. FIG.

(Step S1038)
Next, the CPU 100 performs an electrode sensitivity value correction process.
In this process, the “offset value” of the capacitance value of each electrode is calculated from the area of the overlapping portion of each electrode obtained in the above-described Kira card area calculation process.
Regarding the offset value of each electrode,

(Offset value of each electrode) = (Area of overlapping part of each electrode) × (Coefficient) …… Equation (4)

It can obtain | require using Formula like. The coefficient can be stored in the storage unit 110 as a predetermined constant by previously obtaining the relationship between the capacitance and area of a normal card and a Kira card.
The CPU 100 also stores the obtained offset value of each electrode as an array variable or the like corresponding to each electrode.

(Step S1039)
In step S1039, processing similar to that in step S1025 is performed, and each of the sensor microcomputers 310-1 to 310-n performs scanning processing.

(Step S1040)
Here, the CPU 100 performs electrode coordinate acquisition / offset processing.
First, in this process, the CPU 100 performs an electrode coordinate acquisition process similar to step S1026. That is, the CPU 100 reads out the capacitance values acquired from the respective sensor microcomputers 310-1 to 310-n from the storage unit 110.
Then, the CPU 100 reads out the offset value of each electrode described above from the storage unit 110 and performs a process of adding or subtracting it to the capacitance value corresponding to each electrode.
As a result, it is possible to cancel the malfunction due to the glitter card and to accurately detect the contact of the cards 80-1 to 80-n.
Thereafter, the CPU 100 erases the array of offset values of each electrode by performing zero fill or the like.

(Steps S1041 to S1043)
Step S1041 performs the same processing as Step S1028, Step S1042 performs Step S1029, and Step S1043 performs Step S1030.
As described above, (2) the process of detecting the cards 80-1 to 80-n including the special “kira card” including the metal foil or the like is completed.

By configuring in this way and using the touch position acquisition by the respective sensor microcomputers 310-1 to 310-n and the processing of the image acquired by the infrared camera 260, detection of the position touched by the user in the play field 60 Can be 400 points or more, for example, over the entire play field 60.
Thereby, when each card 80-1 to 80-n for play is about 86 mm × 54 mm in size, it is possible to obtain a resolution that can be divided into six without much cost. It is also possible to have a resolution for obtaining points that can be divided into nine.

In addition, in game device 10-1 according to the embodiment of the present invention, it is possible to detect a contact position of 60 times / second or more for 400 points in play field 60. This is a sufficiently high speed as compared with the conventional technique for optically detecting only the code. That is, when the user touches the cards 80-1 to 80-n, the contact position can be detected almost in real time at a very high speed.
The drawing speed of a moving image that can be perceived by the human eye is about 60 frames / second, and this 60 frames / second is a drawing speed generally used in games.
For this reason, the drawing speed, the code detection speed, and the contact position detection speed can be matched, and the reaction of the game apparatus 10-1 is delayed (heavy) in comparison with the instruction from the player P in the game. It becomes possible to avoid.
In particular, in a real-time simulation game, the game situation is greatly affected by the speed of instructions for the placement of each unit, so the reaction speed is very important in the fun and operability of the game. For this reason, the large effect which improves the operativity of a card game is acquired by providing sufficient detection speed like the card | curd detection method concerning embodiment of this invention.

(Step S303)
Here, referring again to FIG. 13, the specific processing of the card game after card detection will be described in detail.
The CPU 100 performs a teammate process. In this ally unit process, the CPU 100 obtains various instructions by arrangement of the cards 80-1 to 80-n and contact of the cards of the player P in FIG. To perform the process. As this action, the player moves to a destination or battles with an enemy unit operated by the CPU 100 or another player. The results of these processes are reflected by the drawing process after the next enemy unit process.
In the following, with reference to FIG. 21 to FIG. 24, the ally unit process in step S302 will be described in more detail.

[Composition of unit]
First, with reference to FIG. 22, the data regarding the unit will be described. In the card game of the game system X according to the embodiment of the present invention, each unit has data of a unit such as a friendly unit, an enemy unit, and a neutral unit, and the game progresses according to the state of the unit.
FIG. 22 shows an example of data elements related to a teammate. As elements of this data, elements such as a unit number D101, a leader number D102, a command D103, a special attack level D104, a target D105, a morale D106, and a member D107 can be provided.
The unit number D101 is a part (unit number storage unit) that stores a number used on the program corresponding to each unit. For example, when cards 80-1 to 80-n of the same military commander (type) are used in the card game, they can be distinguished and used by this unit number D101.
The leader number D102 is a part (military storage unit) that stores a number indicating the character of the military commander of the cards 80-1 to 80-n associated with the unit number. When the same type of card is used, the card can be distinguished from each other using the ID of the card.
The command D103 is a part (behavior information storage unit) that stores data of a command of a unit action determined by the unit action instruction process.
The special attack level D104 is a part (special attack level storage unit) that stores a “special attack level” used for a special attack described later. This special attack level increases with the time of pressing (contacting) the cards 80-1 to 80-n associated with the unit numbers and the pressing (contacting) strength (contact area), and decreases with a special attack. Or it becomes 0. It can also be set to increase the “special attack level” in proportion to the time the unit was attacked and the amount of damage.
The target D105 is coordinates on the map or a part (coordinate information storage unit) indicating a unit to be pursued. This target D105 can be determined by the arrangement of the corresponding cards 80-1 to 80-n.
The morale D106 is a part (morale parameter storage unit) that stores parameters related to morale such as the strength of the unit's battle, ease of turning over, and ease of attack. For example, the lowest morale can be 0 and the maximum morale can be 255.
The member D107 is a part (member character storage unit) that stores a list of member characters. This member is variable except for the leader. For example, it is possible to perform operations such as joining the units and distributing them with other units, or acquiring and increasing the number of characters turned over from the enemy units. It is also possible to operate different characters such as archers and cavalry as the same unit.
Note that data such as the morale D106 and the number of members D107 and the types of characters can be stored in the IC card 85.

[Character structure]
Next, with reference to FIG. 23, data relating to a character of a unit will be described.
In the card game according to the embodiment of the present invention, the CPU 100 causes each character to act as each member of the unit of the card game unit, and is displayed on the map three-dimensionally drawn by the graphic processor 160.
In the card game according to the embodiment of the present invention, as the types of characters, a leader character corresponding to each of the cards 80-1 to 80-n and a “character other than the leader” serving as a normal unit member appear. be able to.
Data elements related to each character may include elements such as member number D201, name D202, HPD 203, LVD 204, occupation D205, skill D206, gender D207, ability value D208, leader D209, item / equipment D210, and the like.
The member number D201 is a number associated with each member character. This number can be added by the CPU 100 according to the program every time the card game is played.
The name D202 is an element indicating the name of the character. In the case of a leader character, this name is set as a default name, and can be named by the player P in FIG. Such a reader character name can be stored in the IC card 85. The name of the character other than the leader can be set from a predetermined name list by the CPU 100 using a program every time the card game is played.
The HPD 203 is an element indicating the physical strength value of the character. When HP reaches 0, the character dies. The HP value can be restored to the user's support or automatically when in a particular location, such as a castle or other position on the map. Also, when the leader's HP becomes 0, the leader cannot be used as “uncombatable” while the game is being played. During recovery, a parameter on the card game called “Hyogi” decreases.
The LVD 204 is an element indicating a level such as character strength. The level of the leader increases depending on the number of times played and the number of special attacks. The levels of characters other than the leader in the same unit are specified in the scenario or set by the CPU 100 at the start of game play according to the level of the leader.
The occupation D205 is an element indicating “occupation” related to the appearance, skill, etc. of the character on the polygon drawing. There are various categories for leaders such as military commanders, soldiers, and ninjas. Furthermore, special categories such as “future person”, “makaijin”, and “android” may be prepared for the above-mentioned Kira card. According to this category, leader occupations can have occupational attributes such as Daimyo, territory, villager, first leader, monarcher chief, and Shinobu. Further, the occupations of characters other than the leader in the same unit can be used mainly for the characters constituting the unit, such as cavalry, archer, mercenary, and foot. This profession can be set according to the ratio when distributing the forces that can be moved on the scenario by the user to each unit after the scenario reading process. In “Campaign Mode” and “Nationwide Conquest Mode”, the ratio of the soldier's occupation is stored in the IC card 85 for each leader, and the soldier's occupation is set at this ratio as the card game progresses. You can also
The skill D206 is an attribute possessed only by the leader and stores a special attack method to be executed at the time of a special attack. The skill D206 can be increased with the value of the level D204 of the leader character, or the skill of the enemy unit leader can be “learned”.
The sex D207 is a value related to the sex such as male, female, and neutral, and the character of the character. Depending on this gender and personality, values such as the ability to execute instructions by the user and the courageousness toward the enemy units change during the game. The value of this attribute of the leader also affects the attribute values of characters other than the leader.
The ability value D208 is an attribute indicating the ability assigned specifically for each character. The attribute value of the ability value D208 can be expressed by an increase or decrease from a predetermined value at the same level. For example, a character whose member number D201 is 100 in FIG. 23 has an AG (Agility) value of +50 and a DF (Defense) value of +20. This ability value can be changed by the value of other attributes such as occupation D205 and item / equipment 210.
The leader D209 is a flag indicating whether or not the character is a leader. Of course, it is possible to adopt a configuration in which the leader character and other characters have different data.
The item / equipment D210 is an attribute that indicates an item that the character equips or equips. It also remembers the attribute of whether or not equipped. Further, the value of the other attribute also changes depending on the attribute value of the item / equipment D210.
Note that it is also possible to store the data of each character for the player P in the server 5 and download and use it for each play.

(Step S2011)
Here, with reference to the flowchart of FIG. 21, the details of the ally unit process will be described in more detail.
First, in step S2011, the CPU 100 performs a card unit handling process.
Specifically, the CPU 100 searches the acquired card information, and associates the cards 80-1 to 80-n arranged in the play field 60 with the ally unit that performs processing. In the following example, it is assumed that the card 80-1 is associated with a unit having a unit number D101 for processing of 1.
Then, the CPU 100 associates the coordinates of the play field 60 of the card 80-1 with the coordinates on the corresponding card game map. As a result, the “movement position” on the map instructing the unit performing the processing can be acquired. This movement position is stored in the target D105 of the unit performing the processing. When an enemy unit exists at a position on the map, the enemy unit can be stored in the target D105.
Then, the CPU 100 calculates how far these coordinates have moved from the position in the previous frame. As a result, the “acceleration” instructing the unit performing the processing can be acquired.

If the card 80-1 to 80-n arranged in the play field 60 and the unit performing the processing cannot be associated with each other for a predetermined number of seconds, the card is determined to be in the play field 60. Judged to have been removed from.
In this case, it is determined that the player P has instructed the unit to be processed to move to the coordinates where the reserve unit such as “castle” is arranged. Alternatively, it may be determined that an instruction to “retreat” is given outside the screen.

(Step S2012)
Next, the CPU 100 performs card contact time acquisition processing.
Specifically, the CPU 100 determines whether or not the card is in contact with the touch information of the card information of the card 80-1 associated with the unit to be processed, Pressure, contacted area, etc.). In this process, the CPU 100 detects whether the card is touched or the strength of the touch regardless of the position in the card.
Here, when the CPU 100 is in contact with the frame before the predetermined number of frames but is in contact with the frame for a predetermined number of frames, that is, when it is not in contact, It is determined that the card is instructed to be released. Thereby, the contact time (pressing time), which is the time until the card is separated from the contact (non-contact), can be acquired.
In accordance with this contact time, the CPU 100 increases the special attack level D104 of the ally unit that performs processing. Depending on the value of this special attack level D104, the damage (power) given to the enemy in a “special attack” described later changes. Further, it is possible to detect an operation of touching and releasing intermittently (operation of repeating contact / non-contact) such as “tapping”. Thus, it is used for an instruction such as “special action” described later.

(Step S2013)
Next, the CPU 100 performs card contact position acquisition processing.
Specifically, the CPU 100 acquires the coordinates touched in the card 80-1 from the touch information of the card information of the card 80-1 associated with the unit to be processed.
As will be described later, the coordinates being touched are used for action instructions to the unit in combination with the contact time described above.

(Step S2014)
Next, the CPU 100 performs a unit action determination process.
Specifically, as the action of the unit, the CPU 100 first moves the unit to the coordinates of the movement position when the “movement position” acquired in step S2011 described above is different from the coordinates on the current map. It decides to perform the action of movement to move each character. Here, the special attack level D104 is sufficiently high and a special attack is possible, and the player P in FIG. 2 applies a strong contact pressure (increases the contact area) or moves a predetermined distance or more. When the card is moved as described above, the CPU 100 determines an action for performing a “special attack” described later.
In addition, when the CPU 100 performs processing such as touching and releasing the card 80-1 associated with the unit being processed by the user, the attack instruction is basically given. Make a decision to make. At that position, a decision is made to instruct the archer to perform a bow attack or to cause the artillery to attack with a gun. At this time, if a tap has been detected, an attack instruction such as “special action” is determined.
The CPU 100 can make a decision to perform a special attack such as an “interlocked attack” in which the team members are attacked in a coordinated manner when an attack instruction is given when the team members are at coordinates closer than a predetermined distance. Further, in a state where a special attack is possible, when the player P in FIG. If they are released, the CPU 100 determines an action for performing a “special attack” described later.
In addition, when the cards 80-1 to 80-n of other teams are similarly pushed and released (contact state and non-contact state), the CPU 100 determines the action to perform the linked attack. Can do. As a result, it becomes possible to attack the enemy units with more cooperation between allied units than in the conventional real-time simulation. Also, this “linked attack” can be used in combination with a special attack.
In addition, when the card 80-1 is in contact, the CPU 100 can make a decision to instruct the basic action of the unit such as “attack” or “defense” according to the contacted coordinates. .
In addition, when the CPU 100 detects that the user has touched the switch 240 in FIG. 2, the CPU 100 can display a menu screen or the like and make a decision to give optional instructions such as joining, recovery, or withdrawal of units. Note that an option instruction such as “recovery” can be selected only when the user is in a friendly position such as a castle, and other instructions can be rejected while the option instruction is being executed.

(Step S2015)
Next, the CPU 100 determines whether a unit battle is in progress.
This unit battle is determined by the CPU 100 depending on whether there is an enemy unit within a predetermined distance from the instructing unit or whether a long-range attack such as a bow or a gun has been performed on an enemy unit within the range.
That is, if there is an enemy unit within a predetermined distance, the CPU 100 automatically determines “Yes” during the unit battle, and otherwise determines “No”.
And when determination in step S2015 is Yes, CPU100 advances a process to step S2016.
Conversely, if the determination in step S2015 is No, the CPU 100 advances the process to step S2017.

(Step S2016)
The CPU 100 performs battle action processing.
In the battle action process, the CPU 100 controls each character so as to attack the enemy unit located closest to each character.
Specifically, the CPU 100 selects an attack means for each character according to the weapon and occupation mainly equipped in the item / equipment D210, and causes the character to perform an attack. If it is selected, a “special attack” is performed. This attack or special attack “hits” the character of the enemy unit according to the random number, the range and coordinates of the attack means, the level D204 and the ability value D208 of each character.
The attacked enemy unit character decrements the value of HPD 203 if the attack hits. At this time, the CPU 100 obtains the HPD 203 value to be reduced according to the predetermined value of the attack means, the level D204 and the ability value D208 of each character on the attacking side and the defending side.
In this battle action process, the CPU 100 performs a thought process for each character so that characters other than the leader of the same unit protect as much as possible so that the leader character is not attacked as much as possible.

Further, the CPU 100 performs death processing for each character when the HPD 203 of each character is 0. Further, when the leader character dies, the CPU 100 stops the attack instruction and causes the character other than the leader to retreat or cause the enemy unit to “turn over”.
In addition, the CPU 100 increases the morale D106 of the ally unit that performs the processing when the leader character of the enemy unit is defeated. Conversely, the CPU 100 reduces morale when a friendly unit is greatly scraped by an enemy unit.
With this morale D106, the CPU 100 attacks the enemy unit without following the action instruction or escapes. When the escape process is performed, the CPU 100 reduces the morale D106.
When the battle process for each character of the team member performing the process is completed, the CPU 100 advances the process to step S2018.

(Step S2017)
The CPU 100 performs other behavior processing. In this other action process, a movement process for moving each character of the unit toward the coordinates set for the target D105 and the unit, an option process according to an option instruction from the menu, and the like are performed.
Note that the CPU 100 controls each character so as to avoid obstacles during the movement process.
Thereafter, the CPU 100 advances the process to step S2018.

(Step S2018)
Here, the CPU 100 determines whether all the friendly units have been processed.
This “all team members” determines whether or not processing has been performed for all team members that can be instructed by the user. If a unit has retreated or is in a state where an option instruction such as “recovery” has been executed and cannot be instructed, the unit is not determined to process, and may have been processed. it can.
When it is determined as “Yes” in the determination in step S2018, that is, when all the ally units are processed, the CPU 100 ends the ally unit process.
Conversely, when it is determined as “No” in the determination in step S2018, that is, when there is still a team member to be processed, the CPU 100 returns the process to step S2011 and performs each process for another team member.

(Step S304)
Here, with reference to FIG. 13 again, main game processing will be described.
In step S304, the CPU 100 performs enemy unit processing. About this enemy unit process, the process which makes each character in an enemy unit act based on the instruction | indication transmitted from CPU100 or other game devices 10-2 to 10-n of an opponent is performed.
This action includes other actions such as battle and recovery, similar to the above-mentioned friendly unit process.
When the CPU 100 issues an action instruction, the instruction is given artificially with reference to the strength or the like using an αβ method, a Min-Max method, or the like. However, since the action of each unit is performed by the CPU 100, it does not always move according to the instruction.
If there is a neutral unit in the scenario, or if there is an event, the processing can be performed after this enemy unit processing. The neutral unit processing can be performed in the same manner as the enemy unit CPU 100 processing, and the behavior can be instructed in the scenario. For the event, the CPU 100 executes an event such that, for example, another enemy unit appears after a predetermined time has elapsed after the scenario play is started.

(Step S305)
Next, the CPU 100 performs drawing / behavior execution processing.
In this process, the CPU 100 uses the graphic processor 160 to display each character of each unit using a polygon or the like on a map drawn in a three-dimensional space. Moreover, the action including the battle of each unit is executed with specific image effects.
Hereinafter, specific processing of the drawing / behavior execution processing will be described with reference to FIGS.

Referring to the conceptual diagram of FIG. 24, the CPU 100 schematically shows a card game play screen displayed on the display 270 using the graphic processor 160. The play screen mainly includes an arrangement screen 1010, a castle 1020, an inaccessible zone 1030, a base 1040, a direction bar 1050, a teammate unit icon 1080-1 to 1080-n, and a teammate unit damage level 1085. -1 to 1085-n, special attack possible marks 1087-1 to 1087-n, enemy unit icons 1100-1 to 1100-n, enemy unit damage levels 1105-1 to 1105-n, and character 1500 Objects are displayed.
The arrangement screen 1010 displays the icons of the characters of each unit or leader on the schematic diagram of the map screen. The arrangement screen 1010 can be displayed correspondingly when the player P in FIG. 2 moves the cards 80-1 to 80-n and the unit moves.
The castle 1020 is an object indicating a base having excellent defense power. Of course, it is possible to express a castle on a three-dimensional model instead of such an object.
The inaccessible zone 1030 indicates a place where the unit cannot move, such as a steep mountain, a large river, a lake, or a castle wall on the map. In addition, when a character equipped with a specific item in the item / equipment D210 is included in the unit, or in the case of a character of a specific occupation such as a ninja, it is possible to proceed beyond this inaccessible zone. is there.
The base 1040 is a display indicating a location on the map that needs to be acquired in a scenario or is a resting destination for a teammate. Normally, when either an enemy unit or a friendly unit comes within the position, the position is acquired by the enemy or the player P. Whether or not a base has been acquired can be represented by a color or the like. You can also choose options for recovery, etc., at positions that your team has acquired.
The direction bar 1050 is an object that displays the direction on the map where the three-dimensionally drawn portion is displayed. The CPU 100 detects the operation of the switch 240 and moves the viewpoint (virtual camera, virtual viewpoint) in the virtual three-dimensional space of the three-dimensional drawing. Then, the graphic processor 160 can display the image with enlargement / reduction / rotation.
The CPU 100 calculates and displays a direction bar according to this viewpoint, for example, by rotating and enlarging / reducing the map by indicating the upward direction of the map.
The teammate icons 1080-1 to 1080-n are icons indicating teammates on a three-dimensionally drawn map. This icon is displayed corresponding to the cards 80-1 to 80-n arranged on the play field 60, and the texture information such as the illustration of the leader character indicated by the cards 80-1 to 80-n is displayed as a planar polygon. It is possible to display using a technique such as pasting to the like.
The ally unit damage levels 1085-1 to 1085-n are graph displays showing the average value of the HPD 203 of each character of the ally unit. The friendly unit damage levels 1085-1 to 1085-n can be displayed with the HPD 203 of the leader character by an option instruction.
The special attack possible marks 1087-1 to 1087-n are drawn on the friendly unit icons 1080-1 to 1080-n or the enemy unit icons 1100-1 to 1100-n, and the special attack level D104 of each unit can make a special attack. It is a mark indicating that it is in a state. In addition to the special attack possible marks 1087-1 to 1087-n, a graph display showing the special attack level may be performed.
The enemy unit icons 1100-1 to 1100-n are icons indicating enemy units on a three-dimensionally drawn map. The enemy unit icons 1100-1 to 1100-n are drawn so that they can be distinguished from the teammate unit icons 1080-1 to 1080-n by different background colors.
The enemy unit damage levels 1105-1 to 1105-n are graph displays showing the average value of the HPD 203 of each character of the enemy unit. This graph display is performed in the same manner as the ally unit damage levels 1085-1 to 1085-n.
A character 1500 indicates a character drawn in a three-dimensional space. This character is drawn so as to animate the limbs using a polygon or the like based on the attribute value data.

Of the characters 1500, the leader character can be distinguished by changing the color or drawing a flag.
In addition, the CPU 100 can display a large number of objects related to the terrain and game atmosphere.

  Here, we explain in detail how the user's action instructions are reflected by the drawing / behavior execution process when performing attacks such as “Special Attack”, “Linked Attack”, and “Special Action” To do.

An example of a special attack will be described. When the player P of FIG. 2 performs a “special attack” on the card 80-1 related to a friendly unit composed mainly of a gun unit, the CPU 100 has a more powerful gun attack than usual. It can be performed.
That is, the CPU 100 can greatly reduce the HPD 203 of the enemy character hit by the attack with the gun.

  Further, for example, in the case of a “special action”, when a gun unit that performs a gun attack is used, by performing the above-described “tap”, it is possible to make an attack by exchanging the rows before and after.

Next, an example of the “linked attack” will be described. The game system X according to the embodiment of the present invention supports multiple touches by the touch electrodes 400-1 to 400-n that measure the capacitance.
For this reason, by detecting that the cards 80-1 to 80-n of a plurality of allied units have been contacted and separated, the CPU 100 can attack at the same time by aligning the timing of the attacks of each unit. Become.
The combined attack can cause more damage to the enemy than usual because the personnel concentrate and attack compared to when each unit attacks separately. As a result, it is possible to simulate the battle between a well-trained corps and the general public, and increase the reality of the tactical simulation on the game. Therefore, the user's willingness to improve the game operation can be increased.
In addition, the linked attack can make the user feel that the concentrated dropping of the force is effective, as in the so-called Lanchester's second law (“the law of concentration effect”). For this reason, it becomes possible to express the reality of battle in the game.
With these features of “continuous attack”, the effect of enhancing the realism of the card game can be obtained.

Next, an example of “special action” will be described. When the touch electrodes 400-1 to 400-n according to the embodiment of the present invention reach a special attack level at which a special attack is possible, the card 80-1 By moving ~ 80-n, a “special action” can be performed. This makes it possible to represent situations that determine victory or defeat, such as a horse-riding charge that breaks through the enemy team and divides the enemy units, and a charge of the deceased infantry of the backwater team.
In addition, when the strength of the touch (the size of the contact area) can be detected, it is possible to adjust the speed of the assault by moving the cards 80-1 to 80-n while pressing particularly strongly. .
Further, during the “special action”, the CPU 100 can greatly increase the attack power of the unit, and can collapse the formation. If this “special action” is successful, the CPU 100 increases the morale D106 of the unit by a predetermined large value, and conversely if the enemy unit cannot be broken through, the CPU 100 decreases the morale D106 by a predetermined large value.

Next, an example in the case of instructing actions based on the contact positions of the cards 80-1 to 80-n will be described. As described above, when the contact position of the cards 80-1 to 80-n can be detected within 1/6 or 1/9 in the card, the action instruction changes depending on the position where the user touches the card. Can be made. For example, when the CPU 100 detects a contact on the top (back) of the card 80-1, the CPU 100 can recognize it as an attack action instruction. Further, when the CPU 100 detects a contact below (in front of) the card 80-1, the CPU 100 can recognize it as a defensive action instruction.
The CPU 100 can also be set to change the formation according to the contact position of each card of the card 80-1.

(Step S306)
Here, the description of the game process will be continued with reference to FIG.
In step S306, the CPU 100 determines whether the scenario end condition is satisfied.
As the scenario ending condition, as described above, when all the teams operated by the player P in FIG. 2 are all annihilated, a condition for ending as “defeat” can be set. In addition, when the enemy unit is annihilated, it is possible to set a condition to end as “win”. In addition to this, when a specific unit moves to a specific position on the map or when a leader of a specific enemy unit is killed, the conditions for ending the scenario, such as “Victory” or “Defeat”, are set. It can be set.
If it is determined as “Yes” in the determination in step S306, that is, if the scenario termination condition is satisfied, the CPU 100 advances the process to step S307.
Conversely, when it is determined as “No” in the determination in step S306, that is, when the process is still performed for the friendly unit and the enemy unit in the card game, the CPU 100 advances the process to step S307.

(Step S307)
When the scenario end condition is satisfied, the CPU 100 determines whether the game is over.
A game over is determined to be a game over when the scenario end condition is “defeated” and there is not enough remaining balance. Alternatively, it may be set so that the game is over when one coin is inserted and the player loses several times. Further, when the player P of FIG. 2 is playing in the “national conquest mode”, it can be determined that the game is over when the player P is “defeated” in the scenario and the “territory” is lost.
If the determination in step S307 is “Yes”, that is, if the game is over, the CPU 100 advances the process to step S308.
Conversely, when it is determined “No” in the determination of step S306, that is, when the player P is “win”, the CPU 100 advances the process to step S308.

(Step S308)
If the game is not over, the CPU 100 performs score addition processing.
In this score addition process, the CPU 100 calculates “points” for various conditions at the end of the scenario, and adds the total of the points as a score.
As these various conditions, for example, the CPU 100 can calculate points for the number of enemy units that have been defeated, the amount of damage to allied units, and the amount of time until the scenario end condition.
The CPU 100 displays each point and the total of the points on the display 270 using the graphic processor 160. Further, the CPU 100 stores in the storage unit 110 that the scenario has been cleared.
Then, the CPU 100 increases or decreases the “military funds” and “supply” obtained by the player P in FIG. 2 based on the score acquired in the game. Further, the CPU 100 can change the selection of the scenario to be read next.
Here, in the “campaign mode”, the CPU 100 selects the next scenario. Further, in the “national conquest mode”, the CPU 100 causes the player P to select a scenario of “country” to be attacked next according to the result of the scenario. In the “matching mode”, the CPU 100 causes the player P to select the next opponent or change to the normal campaign mode. In the “scenario selection mode”, the CPU 100 causes the player P to select a cleared scenario. In the case of “tutorial”, the CPU 100 causes the player P to select a normal scenario.
Thereafter, the CPU 100 returns the process to step S301 to play a new scenario.

(Step S309)
If the game is over, the CPU 100 performs a game over process.
Specifically, the CPU 100 calculates points in the case of defeat similarly to the above-described score addition processing and adds them as scores. In this case, the points are calculated less than in the case of victory.
Then, the CPU 100 displays a game over display on the display 270 using the graphic processor 160.
Thus, the game process is finished.

(Step S104)
Here, with reference to FIG. 12 again, the continuation of the flow of the play process of the game apparatus 10-1 will be described.
In step S104, the CPU 100 performs an IC card writing process.
In this processing, the CPU 100 determines the scenario cleared by the player P in FIG. 2 in the game, the level D204 of the character related to each card 80-1 to 80-n, the value of the item / equipment 204, etc. Store in the IC card 85. In addition, in the “campaign mode” and “national conquest mode”, the CPU 100 also stores values relating to the progress of the game, such as the number of characters of each team, the occupation of soldiers, the amount of military funds and the amount of food. Further, the CPU 100 stores the progress of the scenario in the “campaign mode”, and stores the “country” as the territory in the “national conquest mode”.
The IC card 85 may be configured to store all the attribute values of each character.

(Step S105)
Next, in step S105, the CPU 100 performs a card payout process.
The CPU 100 outputs a card similar to the cards 80-1 to 80-n using the card payout unit 230. As described above, this card may be selected randomly, or the number of cards to be output and the type of card may be changed depending on the score. In particular, when a specific progress condition of the scenario is satisfied, it is possible to output a “kira card”.
Thereafter, the CPU 100 turns off the power of the sensor microcomputers 310-1 to 310-n using the peripheral I / F 140.
Thus, the play process of game device 10-1 is completed.

With the configuration described above, the following effects can be obtained.
First, in the prior art 1, in a game using a flat reader that handles a plurality of cards as input devices at the same time, the more information that can be obtained from the user, the better. could not.
On the other hand, in game device 10-1 according to the embodiment of the present invention, touch to user's play field 60 can be detected by using touch panel reading unit 300.

In addition, there are various problems in using a conventional touch panel in a card game device that acquires position information of a plurality of cards by performing image recognition from code shooting by a camera.
For example, for a multi-point touch panel having transparency, a conventional touch panel can only detect two points even if it is small. For this reason, it is difficult to simultaneously recognize a plurality of points, for example, with a 6-inch touch panel. In the past, there was also a small touch panel with a multi-point detection function, but it was not transparent and hindered camera photography with a flat reader.
Therefore, the inventors of the present invention conducted intensive experiments and made various studies on the case of using an imaging unit that adds touch determination for each card in combination with a touch panel.
Below, the advantage and problem at the time of using the conventional touch panel for the game device 10-1 which concerns on embodiment of this invention are described:

・ Ultrasonic surface elasticity touch panel Advantages: Low cost.
Problem: Touching cannot be detected because the card reacts when it is placed. Therefore, it was not usable.
・ Resistive film type touch panel (transparent metal film using ITO)
Advantage: If it is as light as a card, it is placed on the touch panel and does not respond. A touch point can be detected by a pressure change caused by pressing with a finger.
Problem: Only one point could be detected. Moreover, durability was low.
・ Infrared shielding type touch panel (for example, see Japanese Patent No. 4019114)
Advantage: If it is as thin as a card, installing a sensor on the card will not respond to kicking the card. If the card is touched, the finger blocks the light and the touch position can be detected. For example, according to the device of Japanese Patent No. 4019114, it is described that information on which position of the card the player is touching can be obtained (see [0043] and the like).
Problem: Normally only one point can be detected. In other words, contact with a single card can be detected, but when it is desired to detect contact with a plurality of cards, if there is a contact point on the same axis, information indicating that one of the cards has been touched cannot be detected. there were. In addition, even if the finger does not touch the card, it reacts if the light from the sensor is interrupted. Therefore, there is a problem that the finger reacts when the cuff of the clothes touches without touching the card. In addition, the device of Japanese Patent No. 4019114 discloses a device that detects a contact point with respect to a card using the principle of triangulation (see paragraphs [0209] to [0219], etc.). was there.
・ Capacitance touch panel Advantages: Touch position can be detected by changing the electrostatic capacity through the card even if you touch the card.
Problem: There is a problem that usually only one point can be detected.
・ Vibration detection method touch panel Advantage: The position can be detected by vibration when touching even from the top of the card.
Problem: It can only be detected during a touch with vibration. It cannot be detected that the card is being held down. There is also a problem that only one point can be detected.

As described above, the conventional touch panel has various problems for use in the game apparatus 10-1.
For this reason, the game apparatus 10-1 according to the embodiment of the present invention is configured to use a plurality of capacitive touch sensors. This is not merely a matter of design change and could not be easily conceived by those skilled in the art.
Thereby, in the game apparatus 10-1, the touch electrodes 400-1 to 400-n, which are small touch areas, are spread on the game field, and the touch of a plurality of points can be detected by increasing the number of touch sensors. it can. In addition, detection of a plurality of contact positions in the entire play field 60 can be realized, and it can be detected that the card is continuously pressed.
Thus, in game device 10-1 according to the embodiment of the present invention, even if a plurality of cards are arranged, contact can be detected simultaneously for each card, and a card game device with good operability is realized. can do.

In addition, the conventional capacitive touch sensor has a problem in that the cost increases when a plurality of capacitive touch sensors are used. In particular, it has been technically difficult to spread a touch sensor on a large plane such as a play field 60 that is several meters square.
On the other hand, in game device 10-1 according to the embodiment of the present invention, codes 810-1 to 810-n are read with infrared light from the back of cards 80-1 to 80-n, and the card play field. The position on 60 can be detected, and the touch position acquired by the touch panel reading unit 300 can be corrected based on this position. Thereby, the touch electrodes 400-1 to 400-n can be formed as the touch panel sheet 630 by inexpensive screen printing or the like, and sufficient contact position acquisition accuracy can be obtained even when formed at a low density. Therefore, it is possible to detect the contact positions of the cards 80-1 to 80-n with high accuracy at a reduced cost.
In game device 10-1 according to the embodiment of the present invention, touch electrodes 400-1 to 400-n are arranged so as to cover 70% with respect to the area of cards 80-1 to 80-n. Or it can arrange | position so that it may become 1/6 or 1/9. Thereby, malfunction of detection of the contact position of the cards 80-1 to 80-n can be suppressed.
With such a configuration, the place where the player is touching on the play field 60 can be specified with high accuracy, and the game performance can be improved at low cost.

Further, the conventional capacitive touch sensor has a problem that it is difficult to detect in real time several hundred or more touch sensors arranged in a plane.
On the other hand, in the game device 10-1 according to the embodiment of the present invention, by using the sensor microcomputer array 301 such as the sensor microcomputers 310-1 to 310-n, the touch electrodes 400-1 to 400-1 in real time are used. 400-n contact can be detected.
Therefore, in a card game that requires high-speed responsiveness, when the user touches the cards 80-1 to 80-n, the CPU 100 can react immediately, and the operability of the card game can be remarkably improved.

  In the game apparatus 10-1 according to the embodiment of the present invention, an example in which a capacitive touch sensor is used has been described. However, the present invention is not limited to this. For example, a resistance using ITO or the like is used. It is also possible to use a film-type touch panel. Even in this case, it is preferable to form a plurality of touch electrodes with a resistive film like the touch electrodes 400-1 to 400-n because durability can be improved.

When using a capacitive touch sensor, if a card with a low capacitance value containing conductive metal, such as “Kira Card”, straddles multiple sensors, it will not touch. However, since both sensors responded, there was a problem of causing malfunction.
On the other hand, in the game device 10-1 according to the embodiment of the present invention, when the Kira card straddles the electrodes 401 to 400-n, the Kira card and the electrode overlap the acquired capacitance value. Add or subtract an offset value that is proportional to the area that is on. At this time, the overlapping area of the glitter card and the electrode can be calculated from the coordinates of the glitter card of the cards 80-1 to 80-n acquired from the captured image acquired by the infrared camera 260. For this reason, it is possible to cancel the malfunction of the glitter card and detect the contact with the cards 80-1 to 80-n as a value similar to that of a card that is not a normal glitter card.
Further, in the electrodes 400-1 to 400-n, it is possible to detect a change in the capacitance value of a more accurate Kira card and a normal card by performing calibration of electrode characteristics.

As described above, in game device 10-1 according to the embodiment of the present invention:
(1) The touch panel reading unit 300 is substantially transparent and does not hinder photographing by the infrared camera 260.
(2) The number of touch electrodes 400-1 to 400-n can be suppressed by combining the card position information by recognizing the codes 810-1 to 810-n based on the infrared captured image.
It has the characteristics.

Further, in game device 10-1 according to the embodiment of the present invention, a plurality of contact positions of cards 80-1 to 80-n can be detected, and the state of contact and the contact time can be detected. You can also.
For this reason, more information can be obtained from the user, and it has become possible to further expand the range of play (improve playability and enhance game performance). That is, in the playing of a card game, various attack instructions such as “special attack”, “linked attack”, and “special action” can be given, and the operability and presence of the game can be significantly improved.

<Configuration of Game Device 10-1 Using Projector>
Note that the game system X according to the embodiment of the present invention can use a configuration using the projector 275.
Referring to FIG. 25, in addition to the illumination unit 210, a projector 275 can be used to project a card operation, a display related to a unit, and the like on the lower part of the play field 60. In this case, a screen 635 that scatters visible light and transmits infrared light can be provided below or above the touch panel sheet 630.
Referring to FIG. 26, the play field 60 is moved up and down by the player P in FIG. Even with such a configuration, it is possible to place and detect the cards 80-1 to 80-n on almost the entire surface of the play field 60.
Referring to FIG. 27, an example in which a screen 635 that scatters visible light and transmits infrared light is provided below the touch panel sheet 630. This screen uses an optical filter, glass fiber, optical beads, or the like to scatter and display light from the projector 275 on the screen. Thereby, an image can be displayed with high visibility even in the play field 60 which is transparent with respect to infrared rays. Moreover, when an optical bead is used, the effect that the influence of the deformation | transformation by the pressure of the contact of the touchscreen sheet | seat 630 can be avoided is acquired.
Even in the configuration using the projector 275, the progress of the game and the detection of the cards 80-1 to 80-n touched by the touch panel can be similarly performed.

  Note that the configuration and operation of the above-described embodiment are examples, and it is needless to say that the configuration and operation can be appropriately changed and executed without departing from the gist of the present invention.

  The card game device of the present invention can manufacture and sell a card game device that has a high appeal to the user with unprecedented operability by combining a plurality of touch detections by the touch panel and image recognition of the card position. Is possible.
