[D] a game calculation control device for reflecting game information output from the RFID data decoding circuit and the card arrangement direction calculation circuit in game content;
This can be achieved by a card game device provided with card arrangement direction recognition means.

  Here, “... game information output from the card arrangement direction calculation circuit is reflected in the game contents” is not particularly limited, but the character corresponding to the card is changed depending on the card arrangement direction. To change the character's physical strength and items such as weapons possessed, or to change the probability of winning or losing in battle, the score that can be obtained, or to give the right to play a bonus game be able to.

A conventionally known card game device is configured as follows, for example.
In the case of the card game apparatus main body according to the present invention,
A CCD camera for reading a QR code (registered trademark) which is a kind of two-dimensional code printed on a game card;
A circuit that identifies and cuts out a QR code from video captured by the CCD camera, and decodes the QR code;
A card arrangement direction calculation circuit for extracting, as data, an angle rotated in order to convert the QR code from a video into a code video in a correct orientation;
There is provided a game calculation control device for executing the game program while reflecting the game information output from the image data decoding circuit and the card arrangement direction calculating circuit in real time in the game contents.
The CCD camera is arranged facing down on the top of the housing so that the card placed on the card table can be photographed from above.
Further, the casing has, for example, four operation buttons for the player to execute the game.
In addition to the above, the housing includes a display device, a speaker, a power supply device, a charging peripheral device, and other known devices included in a general commercial TV game housing.
In the present invention, an RFID chip is provided instead of the QR code, and an RFID chip reader is used instead of the CCD camera.

As an example of a game suitable for the card game device according to the present invention, for example, a game on the theme of battle between robots can be cited.
In the game, for example, a schematic round clear game called an evil robot (computer) vs justice robot (player) is adopted.
In the game, the player first pays a game fee to the housing (such as inserting coins) and starts the game.
Immediately after the start of the game, in order to select the robot that he / she wants to use, a card on which information on the base machine body of the robot is recorded is placed on the card table of the game apparatus, and the card reading button is pressed. As a result, the CCD camera of the game device captures the card, and the arithmetic unit analyzes the image captured by the CCD camera, and if a QR code is found, the video of the QR code portion is extracted and the extracted QR code is extracted. In addition to analyzing the information, angle information rotated to correct the direction of the cut out QR code image in the proper direction is acquired. The arithmetic unit selects the appropriate base machine and displays it by associating the two pieces of information with information recorded in advance on the game machine side as data for specifying the base machine of the robot.

  Next, in order to equip the robot with an optional unit (such as a weapon), a card on which information on the optional unit is recorded is placed on the card table of the game apparatus, and a card reading button is pressed. As a result, the CCD of the game device captures the card, and the arithmetic unit analyzes the image captured by the CCD and performs the same processing as described above to obtain the two pieces of information, which are prepared in advance in the game program. Select the appropriate option unit by combining it with the information of the option unit, and equip it to the base aircraft.

A robot equipped with an optional unit can basically move and fight automatically by AI, but is configured so that the player can give instructions and perform operations by pressing the attack and defense buttons.
In this case, the history of the buttons of the attack and defense that were pressed is displayed on the screen, and the robot understands the instructions by recognizing the instructions of these buttons at regular intervals. It is desirable that the speed of recognizing the instructions one by one does not react immediately, and the speed is changed depending on the robot and the option unit. Furthermore, if the indication markers arranged in the indication marker stock area are arranged in a certain combination determined for each aircraft and unit, the indication markers are consumed all at once and function as special commands, and the robot responds accordingly. Configure for special actions and attacks.

During the game, the player places an action card on the card table, presses the action button, and captures the QR code of the card with the CCD camera, so that the game device analyzes the video information from the CCD in real time, and the QR code information and The direction is read in real time, and the robot performs the corresponding action according to the type of action obtained from the QR code and its angle.
If you destroy an enemy robot before your robot is destroyed, the round will be cleared. If your robot is destroyed first, the game is over. In order to prevent the action card from being forgotten or misplaced, the image from the CCD camera is analyzed, and a warning is announced until there are no more cards in the card table.

In the above example, the QR code is used as the information input means to the game device. However, the present invention is not limited to this. For example, a bar code or character information can be taken as video information with a CCD camera. If it is information, it will not be restrict | limited in particular.
Also, two RFID chips are built in the same game card, and the two are recorded on the card, which is on the top and which is the bottom. A method that makes it possible to identify the angle is also conceivable. Even in such a case, in the present invention, the arrangement angle information of the game card is configured to be reflected in the game content in real time together with information from the image data described on the game card.

Furthermore, in the above example, an object having game information is a game card. However, the present invention is not limited to this, and it is only necessary to be able to record necessary information. Is not limited.
Accordingly, in the present invention, the term “game card” includes all objects such as boxes and dolls used for game operations.

  With the configuration as described above, in addition to the game information recorded on the game card placed on the card table, the data relating to the arrangement angle of the game card is also adopted as the game information, and both of them are reflected in the game content. It is possible to expand the game contents, which makes it possible to develop various game contents and the like that have not been heretofore, and greatly enhance the interest of the game.

Hereinafter, the card game machine will be specifically described.
At least one image data M is printed on each of the game cards C1, C2, etc. used in the card game machine shown in FIGS.
Specifically, for example, on the game card C1 shown in FIG. 3, a robot design indicating the game content is printed at the center, and one piece of image data (in the case of this embodiment, a QR code) M is displayed at the lower right corner. Is printed.
As shown in FIG. 1, a camera 3 for photographing the game cards C1 and C2 placed on the card table is attached to the upper side of the card table 1 provided in the casing of the game machine. .
Alternatively, the card table 1 is composed of a transparent glass plate or the like, the card C1 or the like is placed face down so that the image data M faces downward, and the card is photographed by a camera attached so as to face upward below the card table 1. You may make it do.

The video data photographed by the camera 3 is brought to the central control device 2 through the I / O port 29, and the image data decoding circuit 21a of the arithmetic unit 21 analyzes the pattern data of the image data (QR code) M, and the card. The QR code image is rotated to the normal position (image processing) so as to correct the inclination of the QR code due to the inclination of the image, the recorded data is decoded, and the card arrangement direction calculation circuit 21b determines the correct position of the QR code. By calculating backward from the rotation angle of the card, it is determined which angle range the card is disposed in.
The game calculation control device 21c receives game information based on the QR code recorded content decoded by the image data decoding circuit 21a and game information based on data related to the card arrangement angle output from the card arrangement direction calculation circuit 21b. While reflecting the game contents, the game program recorded on the hard disk 23 is executed to advance the game.

The inclination of the game card C1 placed on the card table 1 is, for example, as shown in FIG. 3, with respect to the vertical axis Ty of the card table orthogonal to the mutually parallel upper side 1a and lower side 1b. Is set as the angle formed by the vertical center axis Py in the clockwise direction (clockwise).
According to this, the arrangement angle of the card C1 shown in (a) in FIG. 3 is 0 degree, the arrangement angle of the card C1 shown in (b) is 90 degrees, and the arrangement angle of the card C1 shown in (c) is 315 degrees. It is.
This angle can be detected as an angle opposite to the rotation angle at the time of image rotation processing for returning the image data M taken by the camera 3 to a normal direction for decoding the data.
That is, as shown in FIG. 4 (o), when the direction of the left side at the normal position of the QR code M is used as a reference, the slope of the QR code M in FIG. 4 (a) [the card of FIG. Equivalent to the inclination] is 0 degree, the inclination of the QR code M in FIG. 4B (corresponding to the inclination of the card in FIG. 3B) is 90 degrees, the inclination of the QR code M in FIG. [Corresponding to the inclination of the card in FIG. 3 (c)] is 315 degrees. In the image data decoding circuit 21a in which the QR code reading software is installed, these captured QR code images are rotated in reverse by the above angles to return to the normal angles as shown in FIG. Since the QR code is decoded (decoded), the arrangement angle of the card C1 can be detected from the reverse rotation angle in that case.
Accordingly, the arrangement angle of the card C1 shown in FIG. 3A is 0 degree, the arrangement angle of the card C1 shown in FIG. 3B is 90 degrees, and the arrangement angle of the card C1 shown in FIG. 3C is detected as 315 degrees. can do.

In a state where the game information based on is reflected in the game content, the game program is executed to advance the game.
Specifically, for example, in the case of the robot battle game, the game card C1 is a card for selecting the base machine body of the robot, and the QR code M is issued by an authorized game machine manufacturer. Data indicating that the card is a card for selecting a robot base body, and based on the recording information of the QR code M photographed by the camera 3, The game arithmetic control device 21c sets the game machine to a mode for selecting the base machine body of the robot.
Next, when the arrangement angle of the game card C1 on the card table is within a range of, for example, 0 degree or more and less than 45 degrees, the base body of the robot is set to the type of the base body α in FIG. To do.
Further, when the arrangement angle of the game card C1 is in the range of 45 degrees or more and less than 90 degrees, for example, the base body of the robot is set to the type of the base body β in FIG.
Hereinafter, the other six types of base aircraft can be selected at intervals of 45 degrees depending on how the cards are placed on the card table.
In this case, the card arrangement direction calculation circuit 21b determines and outputs within which range the card arrangement angle is, and includes specific shape data of various base aircraft corresponding to each angle range, battle Data relating to the capability and the like is recorded together with the game program and the like on the hard disk 23 of the game machine, and the data of the base machine corresponding to the selection is stored in the hard disk according to the signal specifying the angle range from the card arrangement direction calculation circuit 21b. 23 is read out and applied to the game content.

Next, the player places a weapon selection game card on the card table, sets the game machine to the weapon selection mode, and changes the arrangement angle of the weapon selection card, for example, as shown in FIG. A sword A1, a spear A2, a stone A3, etc. can be selected and determined.
Even in this case, the card arrangement direction calculation circuit 21b only determines and outputs within which range the card arrangement angle is, and includes specific shape data of various weapons corresponding to each angle range, Data relating to the destructive ability and the like is recorded together with the game program and the like on the hard disk 23 of the game machine, and specific data of the weapon corresponding to the selection in accordance with the signal specifying the angle range from the card arrangement direction calculation circuit 21b. Are read from the hard disk 23 and applied to the game contents.

Unlike the robot battle game as described above, for example, a baseball game can be configured by this card game device.
In that case, for example, different players are adopted as game information depending on the angle of the card placed on the table.
For example, it is configured so that a desired 9 players can be selected from 36 players with one card, a specific player is selected with the card direction as an index, and a determination button provided on the game machine is When pressed, the game machine is set so that the game is played based on the personal data of the player.
In that case, for example, zones for designating different players every 10 degrees clockwise from a half straight line extending from the center point of the card along the longitudinal center line of the card are provided for 36 players. .
In one embodiment, one QR code is printed on the back surface of the card, and the game machine photographs the QR code with a digital camera or the like provided on the lower surface of the card table, and the pattern is read by the image data decoding circuit 21a. After analyzing the data, the QR code image is rotated to the normal position, the data is read and decoded, and the card arrangement direction calculation circuit 21b detects the inclination of the QR code from the rotation angle, and from the detected inclination angle. The designated zone is specified, and the designated zone code from the card arrangement direction calculating circuit 21b is input to the game calculation control device 21c together with the QR code data from the image data decoding circuit 21a.
The game calculation control device 21c displays the player's personal data recorded in advance on the hard disk 23 or the like in accordance with the combination of the QR code data and the designated zone code, and when the determination button is pressed, the personal data is Adopted as game data.
In a baseball game, players of each position are determined in a predetermined order by repeating these operations.
The batting order can be input using an appropriate method such as a numeric keypad.

FIG. 6 shows an embodiment different from the previous embodiments for detecting the image data (QR code) displayed on the game card and the card arrangement angle.
On the game card C1 shown in FIG. 6, eight QR codes M1 to M8 are printed at intervals of 45 degrees. And it is comprised so that another QR code may be read according to the arrangement angle of a card, respectively.
That is, when the card C1 is placed on the card table, the QR code present at the uppermost position along the direction of the vertical axis Ty of the table in the photographed image is decoded by the image data decoding circuit 21a. The content is reflected on the game by the game calculation control device 21c.
That is, when the arrangement angle is 0 degree, the QR code M1 is decoded as shown in FIG.
When the arrangement angle is 90 degrees, the QR code M3 is decoded as shown in FIG.
Similarly, when the arrangement angle is 200 degrees, the QR code M5 is decoded as shown in FIG.

In these cases, for example, when a robot battle game is performed, the QR code M1 includes an authentication code for verifying that the card has been issued by an authorized game machine maker, as described above, The base body of the robot selected by the QR code M1 is of the type of the base body α in FIG. Data on the specific shape data of the aircraft α and data on the fighting ability are also recorded.
The same applies to the QR codes M2 to M8, and specific data of the base body of a separate robot is recorded in each QR code.
That is, the QR code displayed at each angular position of the game card C1 shown in FIG. 6 is selected not only according to the information indicating that the robot is the base machine body but also according to the arrangement direction. Specific data regarding the type and shape of the base aircraft, the fighting ability, etc. are also recorded at the same time.
Therefore, when a game card as shown in FIG. 6 is used, angle information is included in the game card itself, and on the game machine side, the image data decoding circuit 21a is placed on the card placed as described above. By reading the QR code at the top position, the angle information of the card can be acquired at the same time.
Therefore, in this case, the image data decoding circuit 21a having the function of reading the QR code at the uppermost position can be regarded as also serving as the card arrangement direction calculating circuit 21b.

  In the above embodiment, a QR code is used as the image data M displayed on the game card. However, the present invention is not limited to this, and any image that can be recognized by a computer such as a barcode or character data taken by a camera. Arbitrary image data can be used.

Next, an embodiment of the present invention, that is, a game card (hereinafter referred to as “RFID card”) attached with an RFID (Radio Frequency Identification) chip, was recorded on the RFID chip according to FIGS. An embodiment in which the RFID card arrangement angle is used as game information together with game information will be described.
In order to detect the arrangement angle of the RFID card on the game table, the invention described in Japanese Patent Application No. 2006-317193 according to Patent Document 5 previously filed by the present applicant can be used.
In this case, for example, two RFID chips are attached to the game card, and the arrangement angle of the card is determined by detecting the positions of the upper RFID chip and the lower RFID chip of the card.
One embodiment will be described with reference to FIGS.
In FIG. 7, the same reference numerals as those in FIG. 2 indicate the same components as those in the embodiment of FIG.

Each of the game cards Cp (p = 1, 2,... S) used in the embodiment shown in FIGS. 7 to 10 has at least two RFID chips Gpq (p = 1, 2,... S, q). = 1, 2,... T) are attached.
Specifically, for example, in the game card C1 shown in FIG. 9, two RFID chips G11 and G12 are attached along one long side thereof.
It is assumed that the RFID chip G11 is attached to the upper position of the card and G12 is attached to the lower position of the card, and data indicating this is recorded in each chip.

A plurality of RFID readers Rij (i = 1, 2,..., N, j for communicating with an RFID chip of an RFID card used as a game card are provided on the lower surface of the card table 1 provided in the casing of the game machine. = 1, 2,... M) are arranged in a grid pattern.
Specifically, for example, an RFID reader Rij is arranged on the lower surface of the card table 1 shown in FIG. 8 so as to be located at each vertex of an equilateral triangle arranged in a lattice pattern.
Hereinafter, when these many RFID readers are individually indicated, numbers 1, 2,... N are sequentially assigned to the arrangement positions in the X-axis direction as shown in FIG. Numbering 1, 2, ... m on the array positions in order, for example, the RFID reader attached to "X-axis position 2, Y-axis position 4" displays "R24" and the same In addition, the RFID reader attached to “X-axis position 9, Y-axis position 7” displays “R97”.

For each of the above RFID readers Rij, for each RFID reader,
A detection circuit Sij (i = 1, 2,..., N, j = 1, 2,... M) is provided. In FIG. 7, in order to prevent complication of the drawing, the radio wave intensity detection circuit Sij is drawn as one block, but actually, each RFID reader has a radio wave intensity detection circuit individually provided. It is what
The function of the detection circuit Sij such as the radio wave intensity is analyzed from the signal wave Wijpq transmitted from the RFID chip Gpq of the game card Cp placed in the vicinity of each RFID reader Rij and received by each RFID reader Rij. For each RFID chip Gpq (p = 1, 2,... S, q = 1, 2,... T), the intensity Fijpq of the received signal wave Wijpq, the ID code IDpq of the RFID chip Gpq, The purpose is to detect information about whether the RFID chip is attached to the upper side or lower side of the card.
That is, when the RFID card Cp is placed at an arbitrary position on the card table 1, the RFID chip Gpq attached to the RFID card responds to a command signal from a nearby RFID reader, and the ID code IDpq is generated. A signal wave Wijpq containing other data is transmitted.
Therefore, the signal wave Wijpq received by a plurality of RFID readers Rij existing around the RFID chip Gpq is analyzed by the radio wave intensity detection circuit Sij provided for each RFID reader Rij, and each signal wave Wijpq is analyzed. Strength Fijpq, ID code IDpq of the RFID chip Gpq, information on the mounting position (upper side or lower side) on the card, and the like are detected. Even if the intensity Fijpq is for the signal wave Wijpq from the same RFID chip Gpq, the distance between the RFID chip Gpq and the plurality of RFID readers Rij is different from each other, but the ID code IDpq is Of course, what is received by any RFID reader Rij is the same as long as it originates from the same RFID chip Gpq.

If this is described with reference to the example shown in FIG. 9, when a game card C1 with two RFID chips G11 and G12 attached is placed on the card table, the signal wave transmitted from the RFID chip G11 will be described. The radio wave intensity of each signal wave W3311, W4211, W5311 and ID code ID11 obtained by receiving by the RFID readers R33, R42, R53 in the vicinity are analyzed by the respective radio wave intensity detection circuits S33, S42, S53 To do.
In this case, since the signal wave intensity is different from one RFID chip G11 to each RFID reader R33, R42, R53, the signal waves W3311, W4211, W5311 respectively obtained in each RFID reader R33, R42, R53 are different. The strength is different.
In contrast, the ID codes included in the signal waves W3311, W4211, and W5311 are the same (ID11) because they are transmitted from one RFID chip G11.
In FIG. 9, only one RFID card C1 is drawn, but actually, there are cases where a plurality of game cards are simultaneously placed on the card table, so each RFID reader R33, R42, R53 Each of them receives signal waves from a plurality of RFID chips. Therefore, the radio wave intensity detection circuit S33, S42, S53 provided for each RFID reader R33, R42, R53 is a signal wave for a plurality of signal waves. Analysis and detection of strength and ID code.

Next, the comparison / selection circuit 21e (FIG. 7) determines the signal wave intensity of the RFID reader Rij from which the signal wave intensity Fijpq is detected for each RFID chip Gpq based on the ID code detected as described above. In order from the highest one, each of the three adjacent RFID readers Rxu, Ryv, Rzw is selected.
That is, in the example of FIG. 9, the signal wave from the RFID chip G11 is received by many RFID readers Rij around it, but the signal wave intensity is adjacent to the RFID chip G11 in the order close to the RFID chip G11. That is, the RFID readers R33, R53, and R42 are selected. That is, the RFID readers R33, R53, and R42 are selected by selecting three RFID readers in descending order of the signal wave intensity from the signal waves including the same ID code ID11 from the RFID chip G11. It will be.

Next, based on the respective signal wave strengths Fxupq, Fyzpq, Fzwpq detected by the three RFID readers Rxu, Ryv, Rzw selected for each RFID chip Gpq provided on the game card Cp as described above. Then, the position Opq of the RFID chip Gpq is obtained by the RFID chip position calculation circuit 21f.
In the example shown in FIG. 9, the signal wave intensity F3311 of the signal waves W3311, W4211, and W5311 transmitted from the RFID chip G11 of the game card C1 and received by the three RFID readers R33, R42, and R53, respectively. , F4211, F5311, the RFID chip position calculation circuit 21f calculates the position O11 of the RFID chip G11.
That is, the intensity of the radio wave transmitted from a specific RFID chip G11 decreases according to the distance from the transmission source, and therefore based on the decreasing function, the transmission output, and the received radio field intensity (all known). By performing the calculation, it is possible to calculate the distances from the RFID chip G11, which is a transmission source, to the RFID readers R33, R42, and R53, respectively. Thus, if the positions of the points corresponding to the above distances are obtained from the three RFID readers R33, R42, and R53, this is obtained as the position O11 of the RFID chip G11.
That is, as shown in FIG. 9, if each of the RFID readers R33, R42, and R53 is centered on a circle having a radius corresponding to the above distance, the intersection of these three circles is obtained as the existence position O11 of the RFID chip G11. It is what

In other words, the signal wave intensities F3311, F4211 detected by the RFID readers R33, R42, R53 without performing calculations for obtaining the distances from the RFID readers R33, R42, R53 to the RFID chip G11, respectively. By selecting the isosensitivity curve corresponding to F5311 (broken circles centered on the RFID readers R33, R42, and R53 in FIG. 9) and obtaining the intersection point, the position O11 of the RFID chip G11 can be obtained. It is.
This calculation process is performed by the RFID chip position calculation circuit 21f.
As described above, based on the signal wave intensities Fxupq, Fyzpq, and Fzwpq detected by the three RFID readers Rxu, Ryv, and Rzw, a calculation method for obtaining the position Opq of the specific RFID chip Gpq that is a transmission source is as follows. Not limited to the above method, any calculation method can be used.
Similarly, the position O12 of another RFID chip G12 of the game card C1 is obtained.

Next, using the position information of the two RFID chips G11 and G12 on the game card C1 obtained by the RFID chip position calculation circuit 21f as described above, the card placement direction calculation circuit 21g causes the placement angle of the game card C1. Is calculated.
That is, the information that the RFID chip G11 is the upper side and the RFID chip G12 is the lower side is obtained from the RFID data decoding circuit 21d that decodes the output signal from each RFID chip on the card. By adding the calculated positional information of both RFID chips, as shown in FIG. 10, the angle α formed by the line connecting these two RFID chips with the vertical axis of the card table can be obtained by calculation. Thereby, the arrangement angle of the game card C1 can be obtained.
These calculations are performed by the card arrangement direction calculation circuit 21g.

The data regarding the card arrangement direction obtained as described above is input to the game arithmetic control unit 21h together with the game information transmitted from the RFID chip and decoded by the RFID data decoding circuit 21d. It is reflected in the game content.
Other means can be used as means for detecting the arrangement angle of the RFID card on the card table.
