Description

The present invention relates to a card front/rear discrimination system, a card game play state display system, and a card body in a card game. More specifically, it mainly relates to technology suitable for TCG (Trading Card Game), which is suitable for distinguishing the front and back sides of cards, and for displaying the status of card game play in places other than the playing area. be.

Currently, most trading cards used in TCG are made of paper (cardboard).
Therefore, in order to display the play status of the TCG at a location other than the play area (for example, remotely), a camera CA is installed in the play area PA where the game is being played to photograph the play status, as shown in Figure 10. The video data from the camera CA is transmitted via an information communication means 1 such as the Internet, and the video data is received and displayed on a receiver and display DP installed at a location other than the play area.

However, as shown in the figure (play area PA), the trading cards TC (1 to 3) used in TCG have an image C1 such as a photograph, illustration, or character displayed on the surface of the card, and In many cases, text information C2 such as explanatory text (text) such as the effects and conditions of use is displayed. That is, the image C1 and text information C2 are often displayed on the front side of the card as front side information.

Therefore, in the trading card images TC' (1 to 3) displayed on the display DP installed in a place other than the play area, the surface information may be difficult to see. For example, although the image C1' is easy to see to some extent, the text information C2' is often difficult to see.
There is a drawback in that a high-performance camera is required to make the surface information, especially the text information image C2', easier to see.

In addition, in Patent Document 1 (Japanese Unexamined Patent Publication No. 11-244537),
Our goal is to provide a card game system that allows the content of data recorded on trading cards to be rewritten in various ways as the game progresses.
"The game control means executes the game program based on data regarding objects that appear in the game and control signals from the controller to advance the game, and outputs image signals and sound signals to the display and sound means. The card medium stores data related to objects that change as the game progresses, and is a card with a built-in memory that allows data to be rewritten.One object is assigned to one electronic card medium, The data related to the object is a value that determines the attributes of the characters that appear in the progress of the game, and changes as the game progresses.The data reading/writing means writes data related to the object stored in the electronic card medium, A card game system is disclosed in which the card game is read out (in the abstract section of the same document).

However, in the card game system of the same document, since it is necessary to use a trading card type electronic card medium, the currently popular trading cards made of cardboard or the like cannot be used.

Also, in Patent Document 2 (Japanese Patent Application Laid-open No. 2009-6131),
``The challenge is to provide a card game machine that can expand the gameplay.''
"A game board equipped with multiple readers/writers that communicate with a semiconductor device capable of wireless communication mounted on a card, and a game board that is connected to the reader/writer and determines the position, orientation, or front and back of the card from the signals of the reader/writer. A card game machine is provided with a control device for detecting data placed on the game board by arranging multiple readers/writers and RF chips on the game board to detect not only the data held by the card but also the signal strength. A card game machine is disclosed that allows the position of an RF chip of a card to be specified in detail.

However, since the card game machine disclosed in this document requires the use of cards equipped with semiconductor devices, it is not possible to use the currently popular trading cards made of cardboard or the like.

Furthermore, in Patent Document 3 (Japanese Patent Application Laid-open No. 2018-33829),
``It is now possible to determine the state of a piece, such as whether it is front or back or the direction of the piece, which makes it possible to completely understand the state of the piece, whether the opponent is a human or a computer match. Our goal is to provide board games that can be played as board games with a higher sense of reality.
"In a board game consisting of a game board and multiple pieces, the game board has a built-in RFID antenna that can recognize the location of each piece on the board, and also has a function to distinguish between the front and back sides of each piece on the board. In addition, a board game having a function of displaying the positions of individual pieces other than on the board or of both individual pieces other than on the board and individual pieces on the board is disclosed.

However, in the board game etc. of the same document, as described in paragraphs 0023 to 0026 of the same document and FIG. Since this method requires at least two RFID tags on the front and back sides with the electromagnetic shield 23 in between, it is not suitable for cards that require thinness.

Japanese Patent Application Publication No. 11-244537 Japanese Patent Application Publication No. 2009-6131 Japanese Patent Application Publication No. 2018-33829

The problem to be solved by the present invention is to make it possible to use currently popular cards with images and text information displayed on the front side, provide a card front/rear discrimination system suitable for cards, and furthermore, To provide a card game play state display system and a card body which can make it easier to see images of surface information in images of trading cards displayed on a display installed in a place other than a play area, including information.

In order to solve the above problems, the card front/back discrimination system in the card game of the present invention is as follows:
A card front/back discrimination system for a card game played using a plurality of cards having surface information expressed on the front surface and card-specific card-specific information, the system comprising:
The card, a recording medium capable of reading and writing card-specific information possessed by the card, a card sleeve capable of storing these cards and the recording medium, and a connection between the back side of the card and the recording medium within the card sleeve. a card body having a sheet-like electromagnetic shielding material interposed between the card body and making it impossible to read the recording medium from the front side of the card;

When the card body is detected by the card body detection means and the card unique information written on the recording medium is not read by the information reading means, the card body is placed on the card storage surface. front/back determining means for determining that the front side is placed on the placement surface with the front side facing downward;
It is characterized by having the following.

Since the card front/rear discrimination system in this card game has the above-described configuration, the following effects can be obtained.
When the card body is placed face up (with the stored cards facing up) on the placement surface of the play area, the card body is detected by the card body detection means, and the recording medium is located below the electromagnetic shielding material. Therefore, the card-specific information written on the recording medium can be read by the information reading means without being hindered by the electromagnetic shielding material. Therefore, the front/back determining means determines that the card body is placed on the placement surface with the front side of the card facing upward.
On the other hand, when the card body is placed face down (the stored cards face down) on the placement surface of the play area, the card body is detected by the card body detection means, and the recording medium is placed above the electromagnetic shielding material. Therefore, the information reading means is prevented from reading the card specific information written on the recording medium by the electromagnetic shielding material. Therefore, the front/back determining means determines that the card body is placed on the placement surface with the front side of the card facing downward (that is, face down).
Further, unlike the technique of Patent Document 3, it is sufficient to store one recording medium in the card body, so it is possible to keep the thickness of the card body thin.
As described above, according to the card front/rear discrimination system in a card game of the present invention, it is possible to use a currently popular card on which an image and text information are displayed on the front side, and also to make it possible to A discrimination system can be realized.

Display means for displaying front information or back information indicating that the card body is facing downward at a position;
It is characterized by having the following.

Since this card game play status display system has the above-described configuration, it is used by the user of this system as follows, and thereby the following effects are obtained.
(1) A user of this system writes one piece of card-specific information to one recording medium on which the card-specific information of the card can be read and written.
As the card used here, it is possible to use a currently popular card (for example, a trading card) on which an image and text information are displayed as surface information.
(2) One recording medium on which one card-specific information is written, a card on which the card-specific information is recorded on the recording medium, and a sheet-shaped electromagnetic shielding material are stored in one card sleeve.
(3) Repeat (1) and (2) above for the number of cards required for card game play.
As a result, recording media, sheet-shaped electromagnetic shielding materials,
This means that the number of sleeves or card bodies in which the cards are housed has been produced as many as necessary for playing the card game, and the player can now play the game using these card bodies instead of the cards.
The above is the advance preparation for playing the game.
(5) The game player plays the game by placing the card body obtained in (2) above in the play area where the card game is played when playing the card game.
(6) When the card body is placed in the play area, the card unique information written on the recording medium of the card body is read by the information reading means, and the position information acquisition means reads the card unique information at the position is acquired as the positional information where the sleeve is placed, and the front and back information of the card body is acquired by the front and back determining means.
(7) The card unique information, position information, and front and back information obtained in (6) above are transmitted to a location other than the play area by the transmitting means.
(8) The card-specific information, position information, and front and back information transmitted in (7) above are received by the receiving means at a place other than the play area, and the display means receives the card-specific information, position information, and front and back information transmitted by the receiving means. Surface information data corresponding to the information is read from the database and displayed as surface information at a position corresponding to the position information on the display screen of the display. Note that when the card body is on the back side, back side information is displayed.
Unlike conventional technology, the surface information displayed in this way is not an image of the surface of the card taken with a camera, but is surface information based on surface information data recorded in a database created in advance. , it can be made easier to see. In particular, text information can be made much easier to see than in the past.

As described above, according to the card game play state display system of the present invention, it is possible to use cards (for example, trading cards) on which surface information is displayed, which are currently in widespread use, while also allowing cards to be displayed in places other than the play area. It is possible to make it easier to see the image of surface information in the image of the card displayed on the installed display.

In this card game play status display system,
The recording medium is a recording medium having a unique UID,
The database may be a UID database in which the UID of the recording medium and unique information of one card corresponding to this UID are recorded.

With this configuration, it is not necessary to write the card-specific information to the recording medium, so a device for writing the card-specific information to the recording medium is not required.

Further, in order to solve the above problems, the card body of the present invention has the following features:
A card having surface information expressed on the surface and card-specific information unique to the card, a recording medium capable of reading and writing the card-specific information possessed by the card, a card sleeve in which these cards and the recording medium are stored; a sheet-shaped electromagnetic shielding material that is interposed between the back side of the card and the recording medium in the card sleeve and makes it impossible to read the recording medium from the front side of the card;
It is characterized by having the following.

This card body includes a card having surface information displayed on the front surface and card-specific information unique to the card, a recording medium on which the card-specific information is written, and a recording medium that cannot be read from the front side of the card. Since the sheet-shaped electromagnetic shielding material is stored in the card sleeve, this card sleeve or card body can be used in place of the currently popular cards with surface information displayed on the surface (for example, trading cards). By using this, it becomes possible to utilize, for example, the card front/rear discrimination system or the card game play state display system in the card game according to the present invention described above.

In this card body,
The recording medium may have a unique UID.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a card front/rear discrimination system, a card game play state display system, and a card body in a card game according to the present invention will be described with reference to the drawings. In each figure, the same or corresponding parts are given the same reference numerals.

FIG. 1 is a diagram showing an embodiment of a card body used in a card front/rear discrimination system and a card game play state display system in a card game according to the present invention.
This card body S' is
A card having surface information represented on the front surface TCf (for example, image C1 and character information C2 represented on the front surface) and card-specific information (for example, card-specific ID (for example, card model number)) CID. T.C. and
a recording medium RF capable of reading and writing card unique information CID possessed by the card TC;
A card sleeve S in which these cards TC and recording medium RF are stored;
In this card sleeve S, a sheet-shaped electromagnetic shielding material SS is interposed between the back side TCb side of the card TC and the recording medium RF, and makes it impossible to read the recording medium RF from the front side TCf side of the card TC. ,
have.

The card front and back discrimination system in the card game of this embodiment is as follows:
The above card body S',
A play area PA that has a placement surface 50s on which the card body S' is placed and is a place where a card game is played (see FIGS. 3 and 5);
Information reading means (51 to 56) and (see Figures 3 and 5),
Card body detection means (51d to 56d) provided below the placement surface 50s of the play area PA and detecting the presence or absence of the card body S' placed on the placement surface 50s;
When the card body detection means (51d to 56d) detects the card body S' and the information reading means (51 to 56) reads the card unique information CID written on the recording medium RF, the card body S' determines that the card TC is placed on the placement surface 50s with the front surface TCf facing upward, the card body S' is detected by the card body detection means (51d to 56d), and the information reading means (51 to 56) When the card unique information CID written in the recording medium RF is not read in the above, it is determined that the card body S' is placed on the placement surface 50s with the front surface TCf of the card TC facing downward. ,
It is equipped with

Since the card front/rear discrimination system in this card game has the above-described configuration, the following effects can be obtained.

In FIG. 9, the information reading means 51 and the card body detection means 51d will be representatively (taken as an example) explained.
As shown in FIG. 9(a), when the card body S' is placed face up (with the stored card TC facing up) on the placement surface 50s of the play area, the card body detection means 51d detects the card body S'. Since the recording medium RF is detected and is located below the electromagnetic shielding material SS, the card-specific information written on the recording medium RF by the information reading means 51 without being obstructed by the electromagnetic shielding material SS. CID is read.
Therefore, the front/back determining means 59d determines that the card body S' is placed on the placement surface 50s with the front surface TGf of the card TC facing upward.

On the other hand, as shown in FIG. 9(b), when the card body S' is placed face down (the stored card TC is face down) on the placement surface 50s of the play area, the card body detection means 51d Since the body S' is detected and the recording medium RF is located above the electromagnetic shielding material SS, the information reading means 51 reads the card specific information CID written on the recording medium RF using the electromagnetic shielding material. It is blocked by the material SS and cannot be read.
Therefore, the front/back determining means 59d determines that the card body S' is placed on the placement surface 50s with the front surface TCf of the card TC facing downward (that is, facing down).

Unlike the technique of Patent Document 3, it is sufficient to store one recording medium RF in the card body S', so it is possible to keep the thickness of the card body S' thin.

As described above, according to the card front/rear discrimination system in this card game, it is possible to use the currently popular card TC in which an image and text information are displayed on the front side, and to also make it possible to A discrimination system can be realized.

Next, a card game play state display method or system will be described with reference to FIGS. 1 to 3.
The card game play state display method or system of this embodiment is a display method or system for displaying the play state of a card game played using a plurality of card bodies S' as described above.

In this display method or system, the number of cards TC required for the card game, the same number of sleeves S, the same number of recording media RF (for example, RF tags) RF, and the same number of sheet-shaped electromagnetic seal materials SS are prepared. do. In addition, in FIG. 1, only one sheet of each is drawn, but in reality, the necessary number of sheets are prepared.

As the card TC, a known commercially available card (for example, a trading card) can be used.
As the sleeve S, a known commercially available card sleeve can be used.
Note that the sleeve S is a synthetic resin bag that can accommodate the card TC, the recording medium RF, and the sheet-shaped electromagnetic shielding material SS. It is desirable that at least the surface side is transparent.
As the recording medium RF, a commercially available known recording medium RF (for example, an RF tag) can be used. As the sheet-like electromagnetic shielding material SS, a commercially known sheet-like electromagnetic shielding material (for example, metal foil such as aluminum foil or copper foil) can be used.

This system (or display method) has the following steps or configuration.
Below, we will also explain how to use it.

(1) One card unique information CID is written to one recording medium RF that can read and write the card unique information CID possessed by the card TC.
The card unique information CID can be written to the recording medium RF by any known appropriate means.
For example, as shown in FIG. 2, the card unique information CID printed at a predetermined location on the card TC (for example, the TCG model number of a trading card) is read by a camera 10 with a character recognition function, and the read card unique information CID is written. The information is written on the recording medium RF by a writing means (for example, an RF writing device) 11.
Note that the card unique information CID can also be manually written into the recording medium RF.

(2) One recording medium RF in which one card unique information CID is written, a card TC in which card unique information CID is recorded on the recording medium RF, and a sheet-shaped electromagnetic shielding material SS are combined into one card sleeve S. (See Figure 1).
A card sleeve (that is, a card body S') in which the card TC, the recording medium RF, and the sheet-like electromagnetic shielding material SS are housed is indicated by the symbol S' in FIG.

(3) Repeat steps (1) and (2) above for the number of cards required for card game play.
As a result, the required number of card sleeves (card bodies S') containing the cards TC, the recording medium RF, and the sheet-like electromagnetic shielding material SS are manufactured.

(4) Surface information data for displaying surface information corresponding to the card unique information CID (for example, image data C1D for displaying image C1, and text information C2 for displaying character information C2 corresponding to card unique information CID) A database 20 (FIG. 3) having character information data C2D) is created.
An example of a table in the database 20 is shown in FIG.
In FIG. 4, RFN (RF1, RF2,...) is the number of the recording medium RF, CID ((CID01, CID02,...) is the card specific information CID, and C1D (C1D01, C1D02,...) is the image The data (image data number) and C2D (C2D01, C2D02, . . . ) are character information (character information number).
The numbers RFN (RF1, RF2, . . . ) of the recording medium RF and the card unique information CID (C1D01, C1D02, . . . ) can be sequentially obtained by the operation (1) above.
The image data C1D (C1D01, C1D02, . . . ) can be obtained by capturing the image written on the card. Furthermore, if the card manufacturer publishes card image data on the Internet, for example, that data can also be used.
The character information C2D (C2D01, C2D02, . . . ) can be obtained by capturing the text written on the card using a camera with a character recognition function or the like. Furthermore, if the card manufacturer publishes the character information of the card on the Internet, for example, that data can also be used.

The above is the advance preparation for playing the game.
Below, the process or structure for playing the game will be explained along with how to use it.

(5) The game player uses the card body S' (see FIG. 1) containing the card TC obtained in (2) above and the recording medium RF, as shown in FIG. 3, when playing the card game. It is placed in the play area PA where the card game is played.

(6) When the card body S' is placed face up in the play area PA, the card unique information CID written in the recording medium RF of the card body S' is read by the information reading means (51) located below the card body. to 56), and the position where the card unique information CID is read is acquired as the position information where the card body S' is placed. Further, the front and back information FBI of the card body S' is acquired by the card body detection means (any one of 51d to 56d) located below the placed card body and the front and back judgment means 59d.
The information reading means 51 to 56 can be constituted by known appropriate information reading means. For example, the configuration described in Patent Document 2 (Japanese Unexamined Patent Publication No. 2009-6131) mentioned above can be adopted. Further, the card body detection means 51d to 56d can be constituted by known detection means, such as a laser sensor or an ultrasonic sensor.
As shown in FIG. 5, in this embodiment, the play area PA is a dedicated game play area provided with a plurality of RFID readers (or reader/writers; the same applies hereinafter) 51 to 56 and card body detection means 51d to 56d. It is composed of a mat 50.
A plurality of RFID readers 51 to 56 are embedded in the position where the card body S' is to be placed (or will be placed).
The acquisition means (position information acquisition means) for acquiring the position information PI where the card body S' is placed may be composed of RFID readers 51 to 56 and a reader/writer control section 59 embedded in the game play mat 50. can. As a specific configuration example, the configuration described in the above-mentioned Patent Document 2 (Japanese Unexamined Patent Publication No. 2009-6131) can be adopted.

(7) The card unique information CID, position information PI, and front and back information FBI obtained in (6) above are sent to a location other than the play area PA (the location where you want to display the card game play status) A2 (Figure 3). .
The transmitting means 61 can be constituted by a known transmitting device.
The transmitting means 61 of this embodiment transmits the card unique information CID, position information PI, and front/back information FBI along with the number RFN of the recording medium RF.

(8) The number RFN of the recording medium RF, the card unique information CID, the position information PI, and the front and back information FBI transmitted in (7) above are received at a location A2 other than the play area PA, with the card body S' facing up. , the image data C1D and character information data C2D as surface information data corresponding to the card unique information CID are read out from the database 20 and displayed on the display screen 41 of the display 40. It is displayed as an image and text information at a position corresponding to the position information PI.
For example, in FIG. 3, when the card body S'(2) (the card body S'(2) stores the card TC2 and the recording medium RF2) is placed face up in the play area PA, the card body The transmission means 61 transmits RFN2 as the number RFN of the recording medium RF2 written in the recording medium RF2 of S'(2), CID02 as the card unique information CID of the card TC2, and data PID02 as the position information PI. These data are received by the receiving means 62, and the image data C1D02 and character information C2D02 corresponding to CID02 as the card unique information CID are read out from the database 20, and are added to the position information PID02 on the display screen 41. The image and text information of the card TC2 are displayed as a video TC2' at the corresponding position. Video TC2' includes an image based on image data C1D02 and text information based on text information C2D02.
Similarly, in FIG. 3, for example, when the card body S'(3) containing the card TC3 and the recording medium RF3 is placed face up in the play area PA, the recording medium RF3 possessed by the card body S'(3) Along with RFN3 as the number RFN of the recording medium RF3 written in , CID03 as the card unique information CID of the card TC3 and PID03 as the position information PI are transmitted by the transmitting means 61, and these data are transmitted by the receiving means 62. The received image data C1D03 and character information C2D03 corresponding to CID03 as the card unique information CID and PID03 as the position information PI are read from the database 20, and the image data C1D03 and character information C2D03 corresponding to the position information PID03 on the display screen 41 are read out. The image and character information of the card TC3 are displayed as a video TC3' at the position.
Note that when the card body S' is placed face down, an image representing the back side of the card is displayed at a position corresponding to the position information PID instead of the above image and text information. The position information PID can be acquired by the card body detection means (51d to 56d) and the front/back side determining means 59d, and the image representing the back side of the card can be stored in the database 20.

Unlike the prior art, the image and character information as surface information in the video TC2' etc. displayed as described above are not images of the front surface TCf of the card TC taken with a camera, but are stored in the database 20 created in advance. Since the image and character information are based on the image data and character information data recorded in the image, they can be easily viewed. In particular, text information can be made much easier to see than in the past.

Note that the receiving means 62 can be configured with a known transmitting device. Based on the card unique information CID, position information PID, and front and back information FBI received by the receiving means 62, image data and character information data or back image data corresponding to the card unique information CID are read from the database 20, A display means for displaying an image and text information or a back image at a position corresponding to the position information PID on the display screen 41 of the display 40 can be configured by the CPU 30 (FIG. 3).

As described above, according to this card game play state display system, it is possible to use currently popular cards TC (for example, trading cards) on which images and text information are displayed, and to use cards other than the play area PA. It is possible to make it easier to see the image of text information in the image of the trading card TC (TC2', etc.) displayed on the display 40 installed at the location A2.

Other embodiments will be described below, mainly with reference to FIGS. 6 to 8.
The main difference between this embodiment and the embodiments described above is that a recording medium RF having a unique UID is used as the recording medium RF, and the UID and the recording medium RF having the UID are placed in a sleeve S. By creating a UID database in which multiple pairs (at least for the number of cards required for the game) are recorded with the card unique information CID of the card being played, it becomes unnecessary to write the card unique information CID to the recording medium RF. That's the point.

With this configuration, it is not necessary to write the card unique information CID to the recording medium RF, so a device for writing the card unique information CID to the recording medium RF is not required.
Note that in this application, "UID" refers to (unique) ID (identification) information unique to the recording medium RF, which is recorded in advance (for example, at the time of manufacturing) on the recording medium RF.

A detailed explanation will be given below, just in case.
The card game play state display system (or method) of this embodiment includes an image C1 as surface information represented on the surface, character information C2 represented on the surface, as shown in FIG. 1, for example. This is a system that displays the play status of a card game played using a plurality of cards TC having card-specific information CID (for example, card-specific ID (for example, card model number)) and CID.

This system prepares the number of cards TC required for a card game, the same number of sleeves S, the same number of recording media RF (for example, RF tags) having unique UIDs, and the same number of sheet-shaped electromagnetic shielding materials SS. do. In addition, in FIG. 1, only one sheet of each is drawn, but in reality, the necessary number of sheets are prepared.
As the card TC, a known commercially available card (for example, a trading card) can be used.
As the sleeve S, a known commercially available card sleeve can be used.
As the recording medium RF, a known commercially available RF tag having a unique UID can be used.

The display system of this embodiment has the following steps and configuration.
Below, we will also explain how to use it.

(1) The unique information CID of one card is associated with the recording medium RF having a unique UID and recorded in the UID database 70 (see FIG. 6).
For example, as shown in FIG. 6, the card unique information CID (for example, TCG model number) printed at a predetermined location on the card TC is read by the camera 10 with a character recognition function, and the read card unique information CID is stored in the UID database 70. At the same time, the UID unique to the recording medium RF read by the recording medium RF reading device 65 is recorded in the UID database 70 in association with the card unique information CID.
Note that the card unique information CID can also be recorded in the database 70 by manual input.
An example of a table of the UID database 70 is shown in FIG.
In FIG. 8, UID (UID01, UID02, . . . ) is the UID of the recording medium RF, and CID (CID01, CID02, . . . ) is the card specific information CID.
The UID (UID01, UID02, . . .) of the recording medium RF and the card unique information CID (CID01, CID02, . . .) can be sequentially obtained by the operation (1) above.

(2) The recording medium RF used in (1) above, the card TC, and the sheet-like electromagnetic shielding material SS are housed in one card sleeve S (see FIG. 1).

(3) Repeat steps (1) and (2) above for the number of cards required for card game play.
As a result, the required number of card bodies S' are produced.
Further, a UID database 70 is constructed in which the UID of the recording medium RF and the card unique information CID paired with the UID are recorded for the number of cards necessary for the game.
An example of a table of the UID database 70 is shown in FIG.
In FIG. 8, UID (UID01, UID02, . . . ) is the UID of the recording medium RF, and CID (CID01, CID02, . . . ) is the card specific information CID.
The UID (UID01, UID02, . . .) of the recording medium RF and the card unique information CID (CID01, CID02, . . .) can be sequentially obtained by the operation (1) above.

(4) A database 20 (see FIG. 3 , Figure 7).
An example of a table in the database 20 is shown in FIG.
In FIG. 4, RFT (RF1, RF2,...) is the number of the recording medium RF, CID (CID01, CID02,...) is the card specific information CID, and C1D (C1D01, C1D02,...) is the image data (image data number) and C2D (C2D01, C2D02, . . . ) are character information (character information number).
The numbers RFN (RF1, RF2, . . . ) of the recording medium RF and the card unique information CID (CID01, CID02, . . . ) can be sequentially obtained by the operation (1) above.
The image data C1D (C1D01, C1D02, . . . ) can be obtained by capturing the image written on the card. For example, if a card manufacturer publishes card image data on the Internet, that data can also be used.
The character information C2D (C2D01, C2D02, . . . ) can be obtained by capturing the text written on the card using a camera with a character recognition function or the like. For example, if a card manufacturer publishes card character information on the Internet, that data can also be used.

The above is the advance preparation for playing the game.
Below, the process or structure for playing the game will be explained along with how to use it.

(5) The player places the card body S' (see FIG. 1) obtained in the above (2) in the play area PA where the card game is played, as shown in FIG. 7, when playing the card game.

(6) When the card body S' is placed face up in the play area PA, the UID of the recording medium RF that the card body S' has is read by the information reading means (any one of 51 to 56), and the UID is The read position is acquired as position information PI where the card body S' is placed.
The information reading means 51 to 56 can be constituted by known appropriate information reading means. For example, the configuration described in Patent Document 2 (Japanese Unexamined Patent Publication No. 2009-6131) mentioned above can be adopted.
In this embodiment, the information reading means is comprised of a game playing mat 50 in which a plurality of RFID readers 51 to 56 are embedded.
A plurality of RFID readers 51 to 56 are embedded in the position where the card body S' is to be placed (or will be placed).
The acquisition means (position information acquisition means) for acquiring the position information PID where the card body S' is placed may be composed of RFID readers 51 to 56 and a reader/writer control unit 59 embedded in the game play mat 50. can. As a specific configuration example, the configuration described in the above-mentioned Patent Document 2 (Japanese Unexamined Patent Publication No. 2009-6131) can be adopted.
Note that the case where the card body S' is placed face down is the same as in the embodiment described above.

(7) The UID and position information PID obtained in (6) above are transmitted to a location other than the play area PA (a location where the card game play status is desired to be displayed) A2 (FIG. 7).
The transmitting means 61 can be constituted by a known transmitting device.
The transmitting means of this embodiment transmits the card unique information CID, position information PID, and front/back information FBI along with the number RFN of the recording medium RF.

(8) The UID and location information PI of the recording medium RF transmitted in (7) above are received at a location A2 other than the play area PA, and the surface information corresponding to the UID and/or card unique information CID The image data C1D and character information data C2D are read out from the UID database 70 and the database 20, and the image and character information ( surface information).
For example, in FIG. 7, when a card body S'(2) containing a card TC2 and a recording medium RF2 is placed in the play area PA, the UID of the recording medium RF2 that the card body S'(2) has, PID02 as the location information PID is transmitted by the transmitting means 61, those data are received by the receiving means 62, CID02 as the card specific information CID corresponding to UID02 as the UID is read out from the UID database 70, and the card specific information is read out from the UID database 70. Image data C1D02 and character information C2D02 corresponding to CID02 as information CID are read out from the database 20, and video TC2 as image and character information of card TC2 is displayed at a position corresponding to the position information PI on display screen 41. ' is displayed.
Similarly, in FIG. 7, for example, when a card body S'(3) containing a card TC3 and a recording medium RF3 is placed in the play area PA, the UID of the recording medium RF3 that the card body S'(3) has CID3 as the card unique information CID corresponding to UID03 is read out from the UID database 70, and image data C1D3 and character information C2D3 corresponding to CID3 as the card unique information CID are read out from the database 20, and the display screen 41, the image of the card TC3 and text information are displayed as a video TC3' at a position corresponding to the position information PI.
Note that the case where the card body S' is placed face down is the same as in the embodiment described above.

Unlike the prior art, the image and text information displayed in this way are not the image of the front surface TCf of the card TC taken with a camera, but the image data and text information recorded in the database 20 created in advance. Since the image and text information is based on data, it can be easily viewed. In particular, text information can be made much easier to see than in the past.

Note that the receiving means 62 can be configured with a known transmitting device. Based on the UID, position information PI, and front and back information FBI received by the receiving means 62, image data and character information data corresponding to the UID are read from the UID database 70 and the database 20, and displayed on the display screen 41 of the display 40. , a display means for displaying image and character information or displaying it as a back image at a position corresponding to the position information PI can be constituted by the CPU 30 (FIG. 7).
