Description

  The present invention relates to an RFID card reader for reading a bundle of cards having an RFID inlay, an RFID card reading method, and a game apparatus using the same.

  RFID (Radio Frequency Identification) reads contactlessly the ID of the media of a card or a document. The RFID uses radio waves and radio waves in a high frequency (HF) band or an ultra high frequency (UHF) band.

  With such RFID media, when the media overlap, wireless communication becomes difficult. That is, the power supply to the RFID is insufficient, and the frequency characteristic is changed, which makes reading / writing difficult. For this reason, it is desirable that even if the media overlap, they can be read / written collectively.

  As this method, for example, Patent Documents 1 and 2 propose a method of changing the rotational position of the inlay including the antenna on the medium for each medium. In these methods, it is necessary to provide a plurality of inlay media including antennas different in rotational position and installation position, which increases the cost of the RFID media, which is not preferable.

  There is also proposed a method of batch reading a plurality of media tagged with the same antenna shape. For example, Patent Document 3 discloses that a plurality of game cards are provided with an RFID, and the game machine is made to read a bundle of cards at one time.

  Furthermore, Patent Document 4 discloses a technique for providing a guide for shifting the location of a tag such as a plurality of in-lay tag attached file folders including antennas of the same pattern. In Patent Document 5, an optical mark is provided at each end of a card, and after a card bundle is inserted in a lateral direction into a game machine (playing device), the end of the card is mechanically shifted by a lateral shift mechanism. Disclose a technique for batch reading.

  However, in the technology of Patent Document 4, tags are provided at the end of the file folder, and the file folders are arranged in parallel with a certain interval, and it takes time and effort to insert each one. Also, in order to have a fixed interval, it was necessary to take a place more than necessary.

  Further, in the technique of Patent Document 5, a complicated mechanism for shifting so as not to overlap reliably is required for reading the optical marks.

  The present invention relates to an RFID card reader, an RFID card reading method, and a game device capable of reducing a shift in frequency characteristics at the time of reading and improving reading defects, with a bundle in which a plurality of cards having RFID inlays overlap. Intended to be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments are for understanding the present invention, and the technical scope of the present invention is not limited thereto.

  In particular, in the following embodiments, as a card reader, a card can be applied to flat media such as a card itself, a document, a file folder, etc., and these are also included in the card.

(RFID card)
FIG. 1 is an internal configuration diagram of an RFID card according to an embodiment. FIG. 1A is a top view thereof, FIG. 1B is a side view thereof, and FIG. 1C is a plan view thereof. FIG. 2 is a perspective view of the card of FIG.

  As shown in FIG. 1A, the card 1 main body is a flat square. An RFID 2 is installed in the card 1 main body. The RFID 2 is called a wireless tag or inlay. The RFID 2 may be attached to a flat surface.

  The RFID 2 includes a pair of antennas 2-2 and 2-3 and an IC (Integrated Circuit) chip 2-1. The IC chip 2-1 stores information and is readable / writable. In this embodiment, a passive type RFID is shown. The IC chip 2-1 is connected to each of the antennas 2-2 and 2-3.

  The antennas 2-2 and 2-3 form a dipole antenna, receive power by electromagnetic induction by radio waves of a reader described later, and operate the IC chip 2-1. Also, the antennas 2-2 and 2-3 wirelessly transmit read data to the reader and writer according to the instruction from the reader and writer by this operation, wirelessly receive the write data from the reader and writer, and write the data to the IC chip .

  In this example, the RFID 2 is a UHF tag and uses a 920 MHz radio. Also, the RFID 2 may be in the microwave band.

  As shown in FIG. 1 (A), FIG. 1 (B), and FIG. 2, in this embodiment, an elongated RFID 2 including antennas 2-2 and 2-3 is used. That is, the RFID 2 is long in the vertical direction and thin in the horizontal direction in FIG. Then, the RFID 2 is provided along the longitudinal direction of the card 1 main body. With this configuration, as described later, when the card 2 is shifted, the shift amount of the RFID 2 provided on the card 1 can be increased.

  Further, as shown in FIG. 1A, FIG. 1C and FIG. 2, the RFID 2 is provided at a substantially central position in the short direction of the card body 1. Thus, the position of the RFID 2 on the card 1 is constant regardless of the direction of the card 1. When inserting the cards 1 in a bundle, even if the RFIDs 2 are not visible, the positions of the RFIDs 2 of the card deck (card bundle) can be made uniform without worrying about the positions of the RFIDs 2.

  As will be described later, in the present embodiment, the card 1 is a trading card of a trading card game. A character, a weapon, an offensive power, and the like are printed on the front and back surfaces of the card 1, and the IC chip 2-1 stores character parameters of the character, equipment parameters, and the like.

(First Embodiment of Card Reader)
FIG. 3 is a side view of a card reader equipped with a card according to an embodiment of the present invention. FIG. 4 is a front and top view of the card holder on which the card of FIG. 3 is mounted. FIG. 4 (A) is a top view thereof, and FIG. 4 (B) is a cross-sectional view in the card insertion direction. FIG. 5 is a cross-sectional view of the card holder of FIG. 6 is a perspective view of the card reader loaded with the card of FIG.

  As shown in FIG. 3, a plurality of cards 1 are accommodated in the card holder 3. In this embodiment, the card 1 is accommodated in the card holder 3 (also referred to as a card deck) with the longitudinal direction downward. Below the card holder 3, (an antenna of) an RFID reader / writer 4 is provided.

  In FIG. 3, the antenna part of the RFID reader / writer 4 is shown. The RFID reader / writer 4 is readable and writable, and has a flat plate shape. The RFID reader / writer 4 generally has a flat shape. The flat portion generally contains a linear dipole antenna, a flat patch antenna, and the like. A dipole antenna can read an RFID placed in parallel with the antenna. In the case of a patch antenna, the RFID in the vertical direction of the antenna surface can be read.

  On the other hand, as shown in FIG. 4A and FIG. 5, the card holder 3 has a bottom surface portion 3-1, a front sloped guide 3-2 and a back surface sloped guide 3-3. Furthermore, it has right side 3-4, left side 3-5, and top opening 3-6.

  As shown in FIGS. 3 and 6, the bottom surface portion (pushing surface) 3-1 is a surface parallel to the surface of the reader / writer 4. The front end of the bundle of cards 1 is pushed into the inner surface of the bottom portion 3-1 and abuts on it. The rear inclined guide 3-3 is formed to be inclined at a predetermined angle with respect to the surface of the bottom portion 3-1 and the reader / writer 4.

  The back inclined guide (guide surface) 3-3 supports the back of the inserted card bundle. As a result, the bundle of cards 1 inclines at a predetermined angle with respect to the surface of the reader / writer 4 and comes into close contact with its own weight in a state where the front end is shifted at the bottom surface section 3-1.

  The front inclined guide 3-2 is also inclined at a predetermined angle with respect to the bottom surface 3-1 and the surface of the reader 4 in the same manner as the rear inclined guide 3-3. The front inclined guide 3-2 serves to support the card 1 on the front.

  For this reason, the front inclined guide 3-2 does not necessarily have to have an inclination like the rear inclined guide 3-3. Of course, it is desirable that the front inclined guide 3-2 is also formed to be inclined at a predetermined angle with respect to the surface of the bottom portion 3-1 and the reader 4 similarly to the rear inclined guide 3-3. As a result, the inserted card 1 can be held down, and it is possible to prevent the partial collapse of some cards in the card bundle at the time of reading the card.

  The left side 3-5 and the right side 3-4 guide and regulate the side of the card 1. The upper opening 3-6 accommodates the card 1 in a region surrounded by the front inclined guide 3-2, the rear inclined guide 3-3, the bottom surface 3-1, the left side surface 3-5 and the right side surface 3-4. It is a thing.

  Thus, with the front inclined guide 3-2, the rear inclined guide 3-3, the bottom surface 3-1, the left side surface 3-5 and the right side surface 3-4, the oblique slot 3-7 seen from the reader / writer 4 Is formed.

  With this configuration, as shown in FIGS. 3 and 6, the leading end of the bundle of cards 1 inserted in the slot 3-7 is guided by the front inclined guide 3-2 and the rear inclined guide 3-3, and the bottom 3 Hit -1. Therefore, the position of each card 1 in the horizontal direction is shifted by its own weight.

  As a result, when viewed from the plane of the reader / writer 4, the horizontal positions of the RFIDs 2 of the respective cards 1 are automatically shifted from one another. Therefore, the reader / writer 4 can read and write the RFID 2 of each card 1 without deviation of the frequency characteristics (without reading failure due to overlapping).

  In this embodiment, the RFID 2 has an elongated shape and is provided in parallel along the side of the card 1 so that the RFID 2 is eliminated by the shift due to the inclination of the card holder 3, so the shift amount can be increased. .

  Furthermore, the card 1 is housed in close contact with and obliquely stored by the oblique slots 3-7, and in particular, by the rear inclined guide 3-3. Therefore, the distance from the surface of the reader / writer 4 to the RFID 2 of each card 1 becomes uniform.

  As a result, the reader / writer 4 can read and write the RFIDs 2 of each card 1 without deviation in frequency characteristics. Also, unlike the prior art, it is not necessary to provide a space between the cards in order to reduce the deviation of the frequency characteristics.

  For example, when the cards 1 are arranged vertically, 50 sheets of the cards 1 can be stored at intervals, and it is possible to read the cards 1. When the cards 1 are arranged in close contact (vertically), about 5 to 10 Can only read. For this reason, it is effective to closely contact the card 1 and store it obliquely to reduce reading defects of a large number of cards.

  In addition, the positions of the RFIDs 2 in the vertical direction of the card 1 can be shifted from each other by the weight of the card 1, which can be realized without a complicated mechanism. The card holder 3 can be made of a non-metallic material such as resin to prevent interference with radio waves. The card holder 3 is preferably transparent or translucent so that the card 1 in the card holder 3 can be viewed.

  Furthermore, as shown in FIG. 3 and FIG. 4A, the height of the front inclined guide 3-2, the rear inclined guide 3-3, the left side 3-5 and the right side 3-4 is the width of the card 1 Less than the length of the direction. For this reason, the card 1 is exposed at the tip in the height direction.

  Thereby, the card 1 can be easily removed from the card holder 3. Further, even when the card 1 is inserted, it can be easily inserted into the slot 3-7 by holding the tip of the card 1 with a finger. The exposed portion is preferably 1⁄4 or less of the length of the card 1 in the short direction, and preferably 1⁄5 or more.

(Operation of card holder)
FIG. 7 is an operation explanatory view of the card reader of FIG. 3, and FIG. 8 is an explanatory view of an inclination angle in FIG. In FIGS. 7 and 8, the same components as those shown in FIGS. 1 to 6 are indicated by the same symbols.

  As shown in FIG. 7, the back surface inclined guide 3-3 is inclined at an angle θ with respect to the bottom surface 3-1 and the surface of the reader / writer 4. The front end of the bundle of cards 1 inserted into the slot 3-7 is guided by the front inclined guide 3-2 and the rear inclined guide 3-3 and abuts on the bottom surface 3-1. Therefore, each card 1 is also inclined at an angle θ with respect to the bottom surface 3-1 and the surface of the reader / writer 4.

Then, as the amount of deviation due to the angle θ is larger, the overlapping of the antennas of the RFID 2 is alleviated, so that the deviation of the frequency characteristic due to the capacitive coupling between the adjacent RFID 2 antennas is improved, which is advantageous for reading. As shown in FIG. 8, assuming that θ is a tilt angle, W is a thickness of the card 1, and dx is a shift width, the shift width dx is expressed by the following equation.
dx = W / tan θ (1)

  That is, the deviation width dx depends on the inclination angle θ and the thickness W of the card. As the card holder 3 is flipped in the horizontal direction (as the inclination angle θ is reduced), the shift width becomes larger. In addition, as the card 1 is thicker (as the card thickness W is larger), the shift width is larger. Furthermore, when the card 1 is placed in a protective bag such as a sleeve, the thickness W of the card is increased, and the shift width is also increased.

  On the other hand, the more the card holder 3 is inclined in the vertical direction, the smaller the deviation width. If it is tilted in the vertical direction, a desired amount of deviation can not be obtained, and a reading error is likely to occur. The inclination angle θ is preferably 45 degrees or less in consideration of reading accuracy.

  For example, when the thickness W of the card is 0.5 mm and the inclination angle θ is 30 degrees, the deviation width dx is approximately 0.9 mm. When the antenna line width of the inlay 2 is 1 mm, since the deviation width dx is about 0.9 mm, the overlapping can be almost eliminated.

  It is necessary to take into consideration the convenience such as the user's ease of inserting the card, etc. with the inclination angle θ. Therefore, the inclination angle θ is preferably 30 to 40 degrees.

  Further, as shown in FIG. 7, since the card 1 is closely accommodated by the oblique slot, the distance d from the surface of (the antenna of) the reader / writer 4 to the lower end U of the RFID 2 of each card 1 is uniform. It becomes. Thus, the reader / writer 4 can stably read and write the RFIDs 2 of each card 1 regardless of the number of cards 1.

Second Embodiment of Card Reader
FIG. 9 is a perspective view of a second embodiment of the card reader. In FIG. 9, the same components as those shown in FIGS. 1 to 8 are indicated by the same symbols. 9 is different from FIGS. 1 to 4 in that an elongated RFID 2 is disposed at the central position of the card 1 along the short direction of the card 1.

  As shown in FIG. 9, the card 1 is inserted into the slot in the longitudinal direction from the opening in the vertical direction. The leading end (in the latitudinal direction) of the bundle of cards 1 inserted in the slot is guided by the front inclined guide 3-2 and the rear inclined guide 3-3 and abuts on the bottom surface 3-1. Therefore, the horizontal position of each card 1 is shifted.

  As a result, when viewed from the plane (antenna surface) of the reader / writer 4, the vertical positions of the RFIDs 2 of the respective cards 1 are automatically shifted from each other. Therefore, the reader / writer 4 can read and write the RFID 2 of each card 1 without deviation of the frequency characteristics (without reading failure due to overlapping).

  As described above, when the RFIDs 2 of the card 1 are arranged at the same position, even if the long and narrow RFIDs 2 are arranged along the short direction of the card 1, it is possible to prevent the reading failure due to the overlapping of the RFIDs 2 of the card 1.

(Play equipment)
FIG. 10 is a perspective view of the embodiment of the game apparatus using the card reader of this embodiment. FIG. 11 is a block diagram of the game apparatus of FIG. In FIGS. 10 and 11, the same components as those shown in FIGS. 1 to 8 are indicated by the same symbols.

  FIG. 10 shows a trading card game apparatus 10 using the RFID card 1. For example, in a battle game, a card in which a character to be battled, one or more weapons, a protective gear, etc. is written for each of the cards 1 is used. A battle character is set by combining various character cards, weapon cards, and armor cards into a stack of cards (deck) and causing the game apparatus 10 to read them.

  Similarly, a plurality of characters can be set, and a plurality of battle characters are set by variously combining the character cards, the weapon cards and the armor cards of the plurality of respective characters. In such a case, the number of cards in the card deck may be about 50.

  As shown in FIG. 10, the game apparatus 10 has an upright monitor (display panel) 34 and a horizontal operation surface 24 following it. The operation surface 24 is supported by a housing (main body) 22. A card reader (referred to as a card reader) 3, 4 and an operation button 26 are provided on the operation surface 24. A charge receiving unit 30 and a card outlet 32 are provided on the front of the housing 22 below the operation surface 24.

  The monitor 34 can use a known display panel such as a liquid crystal display or an organic EL display. The monitor 34 displays the game content in accordance with the progress of the game. A speaker 28 is provided at the top of the operation surface 24. The speakers 28 play sound effects associated with the game content.

  On the central surface of the operation surface 24, there are provided a front guide 40, a card holder 3 and a rear guide 42 which are obliquely inclined toward the back of the apparatus. As described above, the card holder 3 is provided obliquely to the antenna surface of the reader / writer 4 (not shown).

  Here, it is inclined toward the back of the operation surface. The user inserts a bundle of cards 1 (card deck) into the card holder 3. As a result, the bundle of cards 1 is accommodated in the card holder 3 at a position where the cards are mutually offset in the horizontal direction.

  For this reason, as described above, when viewed from the plane (antenna surface) of the reader / writer 4, the positions of the RFIDs 2 in the vertical direction of each card 1 are automatically shifted from each other. For this reason, the reader / writer 4 can read and write the RFIDs 2 of each card 1 collectively without deviation of the frequency characteristics (without reading failure due to overlapping).

  The front guide 40 and the rear guide 42 are also inclined, and the bundle of cards 1 can be smoothly inserted and removed from the card holder 3. Of course, the front guide 40, the card holder 3 described above, and the rear guide 42 may be disposed obliquely toward the front.

  Operation buttons 26 are provided on the left and right sides of the operation surface 24. The operation button 26 instructs an operation of moving a character displayed on the monitor 34 or using a weapon. By providing the operation buttons 26 on both the left and right sides of the operation surface 24, the operation can be performed with both hands.

  The fee receiving unit (in the figure, the receiving port is shown) 30 accepts coins and collects a game fee. The charge receiving unit 30 may be a device that reads electronic money, such as an electronic money card.

  The card payout opening 32 pays out the card attached with the RFID according to the game result. Depending on the outcome of the game, a new card can be paid out to increase interest in the game.

  Next, as shown in FIG. 11, the control device provided in the case 22 of FIG. 10 includes the processing device 50, the operation unit 52, the output device 54, the printing device 56, and the communication device 58. Prepare.

  The processing device 50 includes a central processing unit (CPU) 60 and a storage device (memory) 62. The CPU 60 acquires the information of the card 1 and receives the selection of the character from the operation unit 52, and performs a process of executing the game. Then, the CPU 60 updates the game information at the end of the game, and writes the update information to the IC chip 2-1 via the RFID card 2 via the reader / writer on the card 1.

  Further, the CPU 60 generates character text and an image according to the game result, and sends the character text and the image to the printing device 56. The printing device 56 prints the generated image on the card 1 attached with the RFID 2 and delivers the printed card to the user from the card outlet 32.

  The storage device 62 stores a game image and character text or image to be printed. The operation unit 52 includes the above-described operation button 26, the card holder 3, the card reader 4, and the charge receiving unit 30 including the coin detector 30A.

  The output device 54 is configured of the monitor 34 described above. The CPU 60 of the processing device 50 is connected to the operation unit 52, the output device 54, and the printing device 56, and performs game display processing and card payout processing according to the game content in accordance with the operation from the operation unit 52.

  Although the game content is arbitrary, for example, in the present embodiment, a predetermined number (for example, 3) of player characters selected from a plurality of (for example, 50) characters prepared in advance and a predetermined number A battle game is played between (for example, three) game machine (computer) characters.

  The character on the player side is composed of the character specified by the identification information of the card 1 acquired by the card reader (the card 1 and the reader / writer 4) and / or the character selected by the operation button 26. Then, in accordance with the operation of the computer-side character on the monitor 34, the battle game proceeds by operating the player-side character with the operation button 26.

  In such a case, a bundle of cards 1 for setting the player's character (card deck) can be read at once even if the number of cards 1 is about 50. As a result, the player can create a card deck having various combinations of characters, weapons, etc., thereby improving the interest of the game.

  Further, since a large number of cards can be read at one time, the reading speed is improved, and it is possible to allow the player to create various combinations of card decks without giving stress to the player.

  The communication device 58 is connected to another game device, and is used to play a competition game with the player of the other game device and the player of the self-play device 10. In addition, the communication device 58 is connected to the host system of the center, and the host system aggregates and displays the game results of a plurality of players who use the game device 10.

(Other embodiments)
Although the card 1 has been described as a card-shaped medium in the above description, the present invention can be applied to flat media such as documents and file folders. Although the RFID 2 is provided parallel to the side of the card, it may be slightly inclined.

  Further, although the RFID 2 is provided at the center position in parallel with the side of the card, it may be at a position shifted from the center position.

  Although the reader / writer 4 has shown the reader antenna part, the antenna of only a reader is also the same structure. Further, in the embodiment of FIG. 3, the bottom surface 3-1 is formed to be flat, but may be formed in a step shape. The bottom surface 3-1 does not have to be parallel to the antenna surface, but the bottom surface (pushing surface) 3-1 with which the card deck abuts supports the card deck with the rear inclined guide (guide surface) inclined at a predetermined angle. Just do it.

  In the embodiment of FIG. 3, the reader antenna surface and the card holder bottom surface are provided in close contact, but this is an example of good reading efficiency, and the reader antenna surface may be disposed anywhere within the range where the RFID 2 can be read. It is also good. Although the reader antenna surface is provided on the bottom surface of the card holder in the above embodiment, it may be provided on the ceiling side. Further, in the design in which the card holder is mounted from the vertical surface, such as the same surface as the charge receiving unit and the lower surface of the display panel 34, the reader antenna is appropriately provided at an appropriate position.

  Furthermore, as described above, a dipole antenna may be used for the reader antenna, and the antenna may be linear or rod-like instead of planar.

  Furthermore, the game device is not limited to the battle game, and may be another game. Further, the positions of the card readers 3 and 4 may be not only at the center of the game apparatus but also at other places, and may be at the front or back of the operation surface in the tilt direction, but also at the right or left good.

  A plurality of RFID cards are accommodated in a card holder having a pushing surface on which the card is pushed when the card is inserted and a guide surface for supporting the card, the guide surface being inclined at a predetermined angle with the pushing surface, Deviation of frequency characteristics at the time of reading can be prevented. Moreover, since it is not necessary to open at regular intervals and to arrange them in parallel, it is not necessary to insert them one by one, and it is possible to prevent taking places more than necessary. Furthermore, since a complicated mechanism is not required, it can be realized with a simple configuration.
