Description

  The present invention relates to a card for a game such as a playing card and a card reader that facilitate the participation of visually impaired people.

  Conventionally, as a playing card that can be used by a visually impaired person, a playing card with Braille has been known (for example, see Patent Document 1).

In addition, techniques called RF tags, IC tags, wireless tags, RFID (Radio Frequency Identification), and the like have been developed. In this technology, the RF tag reader wirelessly transmits radio waves called interrogation waves to the RF tag, and the RF tag returns radio waves called response waves to the RF tag reader in response to the interrogation waves. This is a technique for receiving information in an RF tag and processing the information (see, for example, Patent Document 2 and Non-Patent Document 1).

  According to the card and the card reader according to the present invention, for example, it is possible for a visually handicapped person to quickly and surely know which card is a hand or a place tag, and smoothly. The game can progress.

  First, terms related to the present invention will be described.

  The present invention can be applied to a game using cards, but a description will be given by taking as an example a playing card which is a typical card game. A brief explanation of terms used in playing cards will be given. A suit indicates four types of marks, that is, a spade, a heart, a diamond, and a club. The rank represents 13 kinds of strengths or sizes of A, K, Q, J, 10, 9,... When representing the size of a number, J (jack) is often 11, 11, Q (queen) is 12, K (king) is 13, and A (ace) is 1 or 14. A place is a space for playing games. It may also refer to the area where the card is removed. The hand is a few cards that have been dealt to him at first, and a card at hand when the number of cards changes as the game progresses. In English, it is called a hand. A place tag refers to a card put into play. A place tag is a card that can be influenced by putting out the card, in addition to limiting the cards that the next person can put out. Discarded cards refer to cards that are thrown from the hand into play. In the following description, discard tags are also included in the play cards.

In general, a card used for a card game is composed of several tens of cards. Dozens of cards can be classified into several groups. The above-mentioned playing cards can be classified first by soot. There are four types of soot groups: a spade group, a heart group, a diamond group, and a club group. Moreover, it can classify | categorize according to a rank. There are 13 rank groups: 2 groups, 3 groups,..., Jack group, Queen group, King group, and Ace group. A joker is a group independent of other cards. In the card game, most of the games proceed while judging whether or not the card is the same group. A homogeneous group refers to a case where the same kind of card mark, pattern, number, color, or the like is used. For example, a spade 4 and a spade jack would be the same group of spades. In addition, 4 of spades and 4 of hearts are in the same kind group of 4. The card information is digital information that can identify such a group of cards.
Note that the present invention is also applicable to card games other than the card game.

  The card of the present invention is a card used for a card game and stores card information that is information for identifying the card. For example, the card includes an RF tag, and the card information is stored in the RF tag.

  The card reader of the present invention is a card reader that transmits an interrogation wave to a card, receives a response wave from the card, acquires card information included in the response wave, and outputs a sound based on the card information. The interrogation wave and the response wave in the present invention will be described later. Sound output means that response voice information stored in the card reader is read according to the card information, converted into a response voice signal, and output as sound by an electroacoustic transducer such as an earphone or a speaker. . In addition, it is included in the sound output that the card reading device supplies a response sound signal to the earphone or the speaker and outputs it as a sound. The response audio information is information obtained by converting an audio signal, which will be described later, into digital sample information, or digital information compressed by high-efficiency encoding. The response voice signal is a signal obtained by converting the response voice information into a voltage waveform or a current waveform.

The card reader of the present invention further acquires two or more pieces of card information from a plurality of cards, configures predetermined information regarding the cards based on the two or more pieces of card information, and outputs a sound. The predetermined information related to the card is configured to select response voice information according to a determination result such as whether two or more pieces of card information are the same kind group information or a predetermined combination, or a plurality of response voice information Or converting to a response voice signal. The predetermined combination of card information includes a case where a combination determined by the game is configured.
Embodiments of a card and a card reader according to the present invention will be described below with reference to the drawings. In addition, since the component which attached | subjected the same code | symbol in embodiment fulfill | performs the same function, re-explanation may be abbreviate | omitted.
(Embodiment 1)

  FIG. 1 is a diagram illustrating a usage pattern of a card and a card reader according to the present invention. The visually impaired person 1 who is a game player holds one or a plurality of cards 10 of the present invention in his hand and plays a card game. A card reader 20 is attached to the breast pocket of the visually handicapped person 1. The visually impaired person 1 wears the earphone 2 on the ear. The earphone 2 and the card reader 20 are connected by a cord 3. When the visually handicapped person 1 brings the card 10 close to the card reading device 20, the card reading device 20 reads card information indicating the card type of the card 10 and outputs the sound as a response voice signal.

  The card information indicating the card type is information for identifying, for example, four types of suits of spades, hearts, diamonds, and clubs, and 13 types of ranks of 2 to 10, J, Q, K, and A. Information corresponding to the joker is also included in the card information. Any identification code can be used as long as it can identify a total of 53 cards. In the following description of the embodiment, the soot identifiers S, H, D, and C based on English character information correspond to spades, hearts, diamonds, and clubs, respectively, and J is assigned to the joker. As rank identifiers, numeric information of 2 to 10 is assigned, numeric information of 11 is assigned to Jack, 12 is assigned to Queen, 13 is assigned to King, and 1 is assigned to A. Accordingly, the card information of Spade A is (S, 1), and the card information of Heart King is (H, 13). The joker card information is (J, J).

  The response voice information is, for example, information obtained by digitally sampling a voice signal representing a card type such as “Ace of Spades”, “King of Hearts”, “Diamond 8”, “Club 3”, and the like. Information compressed by high-efficiency encoding may be used. The response audio signal is a signal obtained by converting response audio information into an audio signal waveform.

  The visually handicapped person 1 who is a game player can listen to a response voice signal such as a card type output from the card reader 20 via the earphone 2. Here, only the visually handicapped person 1 can know the card type by the earphone 2.

  A card reader 30 is placed in front of the visually handicapped person 1. The card reader 30 has a built-in speaker. When the card 10 is brought close to the card reader 30, the card reader 30 receives the card information from the card 10 and outputs the card type from the speaker as a response voice signal. The sound output from the speaker can be heard by game participants other than the visually handicapped person 1, so that all participants can know the card type of the place tag placed on the field.

FIG. 2 is a block diagram of the card 10 and the card reader 20 in the present embodiment. The card 10 has a built-in RF tag. A block configuration of the RF tag is shown in a card 10 in FIG. The RF tag in the card 10 includes an antenna 11, a rectifying unit 12, a demodulating unit 13, a modulating unit 14, a storage unit 15, and a congestion control unit 16.
The antenna 11 receives an interrogation wave, which will be described later, and supplies the received interrogation wave signal to the rectification means 12 and the demodulation means 13.
The rectifying means 12 rectifies the received interrogation wave signal, stores it as power supply power in a capacitor built in the rectifying means 12, and supplies power to the circuits of the respective means in the card 10.
The demodulating means 13 demodulates the interrogation wave signal received from the antenna 11 and activates the congestion control means 16 with the demodulated signal.

The storage unit 15 stores the card information and the congestion control time information Ti that are information for identifying the card type of the storage unit 15. The congestion control time information Ti is information used to avoid congestion due to collision of a plurality of response waves transmitted from the plurality of cards 10 when the card information of the plurality of cards 10 is read collectively. Will be described later.
The congestion control means 16 reads the card information from the storage means 15 according to the activation instruction of the demodulation means 13 and supplies the card information to the modulation means 14 after a predetermined time Ti.
The modulation means 14 modulates a high frequency carrier wave signal according to the received card information to generate a response wave signal, supplies it to the antenna 11, and transmits it from the antenna 11.

Next, the configuration of the card reader 20 will be described with reference to the block diagram of FIG. The card reader 20 includes an antenna 21, a demodulation unit 23, a modulation unit 24, a storage unit 25, a control unit 26, an output unit 27, and a battery 28.
The output means 27 is the earphone 2, for example, and only the visually handicapped person 1 hears the sound output.
The modulation unit 24 generates an interrogation wave signal in accordance with an instruction from the control unit 26 and transmits the interrogation wave from the antenna 21. The interrogation wave signal is a high-frequency burst waveform signal. Let Tb be the burst time length of the interrogation wave signal.
The antenna 21 receives the response wave transmitted from the antenna 11 and supplies the response wave signal to the demodulation unit 23.
The demodulator 23 demodulates the response wave signal, takes out card information contained in the response wave signal, and passes it to the controller 26.

  The storage means 25 stores response voice information in the form of a card information / response voice information table as will be described later. The storage section 25 stores reception section information Tmax. Further, the storage means 25 is provided with a temporary storage area as necessary.

The control unit 26 instructs the modulation unit 24 to generate and transmit the interrogation wave signal, searches the card information / response voice information table based on the card information received from the demodulation unit 23, and responds to the card information. The information is read, a response voice signal is generated from the response voice information, and supplied to the output means 27.
The output means 27 converts the received response voice signal into sound and outputs the sound.
The battery 28 supplies power to each unit of the card reader 20.

  Next, operations of the card 10 and the card reader 20 will be described with reference to flowcharts shown in FIGS. FIG. 3A is a flowchart showing the operation of the card 10. FIG. 3B is a flowchart showing the operation of the card reader 20.

  The interrogation wave is a high-frequency radio wave that is intermittently transmitted from the antenna 21 of the card reader 20. The intensity of the radio wave may be weak and reach a few centimeters from the antenna 21. When the card 10 is away from the card reader 20, the signal induced by the antenna 11 is small, and the rectifier 12 cannot charge power. Normally, as shown in (Step S10), the card 10 is in a state of waiting for charging by an interrogation wave. When the interrogation wave cannot be received, the answer is No in (Step S11), and as shown in (Step S10), the card 10 continues to be charged by the interrogation wave, and the card 10 does not transmit a response wave.

When the card 10 is brought close to the card reader 20, the state becomes (step S11), the interrogation wave from the antenna 21 arrives at the antenna 11, the interrogation wave signal is induced on the antenna 11, and the demodulation means 13 is interrogated. Is detected, and the result is Yes in (Step S11). More specifically, an interrogation wave signal is supplied to the rectifying means 12, and the rectifying means 12 charges power and supplies power to each means of the card 10. The demodulation means 13 starts detecting the interrogation wave signal when the power supply is started. When the interrogation wave burst ends, the demodulator 13 detects the end of the interrogation wave, generates an activation signal, and supplies the activation signal to the congestion control unit 16. When the congestion control unit 16 receives the activation signal by the above-described operation in Yes (step S11), the process proceeds to (step S12), and the congestion control unit 16 reads the card information and the waiting time information Ti from the storage unit 15. Next, in (Step S13), the congestion control means 16 starts a built-in congestion time counter. In (Step S14), the congestion control means 16 waits until the count value of the congestion time counter reaches the waiting time information Ti. When the count value of the congestion time counter reaches the value of the waiting time information Ti, the process proceeds to (Step S15), and the congestion control means 16 passes the read card information to the modulation means 14. The modulation unit 14 modulates a carrier wave signal having a predetermined carrier frequency with the received card information to generate a response wave signal, and supplies the response wave signal to the antenna 11. The antenna 11 transmits the received response wave signal. Next, the process returns to (Step S10) and enters a standby state. The demodulating means 13 receives the interrogation wave next time and does not generate an activation signal until the falling edge is detected. Therefore, the congestion control means 16 remains in a standby state.
Next, the operation of the card reader 20 will be described with reference to the flowchart of FIG.

  In card reader 20, in (Step S20) of Drawing 3 (B), an interrogation wave is transmitted intermittently first. Specifically, the control unit 26 instructs the modulation unit 24 to generate an interrogation wave signal intermittently and transmit it from the antenna 21. As already mentioned, the interrogation wave signal is a high-frequency burst signal waveform. The burst time length Tb may be a time length for charging power to the capacitor in the rectifying means 12 of the card 10, and a very short time is sufficient. The trailing edge of the burst of interrogation waves becomes card information read command information for the card 10. After transmitting the burst signal of the interrogation wave, the process proceeds to (Step S21), and the control means 26 starts the counting operation of the built-in Tmax counter. Next, proceeding to (Step S22), the demodulator 23 demodulates the signal from the antenna 21 and passes the demodulated signal to the controller 26. The control means 26 determines whether a response wave signal has been received based on the demodulated signal. Specifically, when receiving any card information from the demodulator 23, the controller 26 determines that a response wave signal has been received. When no card information is received during the time Tmax, the control unit 26 determines No, returns to (Step S20), and causes the modulation unit 24 to transmit the interrogation wave again.

  When a response wave signal is received during the time Tmax, that is, when the control means 26 receives some card information, the control means 26 determines Yes in (Step S22), and proceeds to (Step S23). Then, the modulation means 24 transmits the second interrogation wave. Next, the control means 26 proceeds to (Step S24), restarts the counting operation of the Tmax counter, and proceeds to (Step S25).

  The reason why the interrogation wave is transmitted twice is as follows. When reading a plurality of cards 10, if the timing of bringing the cards 10 close to the card reader 20 is close to the falling time of the burst of interrogation waves, the power supply power is insufficiently charged, and all the cards 10 generate activation signals simultaneously. Not necessarily. In the first interrogation wave, there is a possibility that the card reader 20 cannot acquire a part of the card information in the hand, so the control means 26 does not use the card information at this time. Since all cards 10 can generate an activation signal for the second interrogation wave, all the cards 10 transmit a response wave, and the card reader 20 can acquire the card information of all the cards. Note that the card reader 20 does not necessarily need to extract card information from the response wave for the first interrogation wave, and may only detect the presence or absence of reception of the response wave.

  In step S <b> 25, upon receiving the response wave signal from the antenna 21, the demodulation unit 23 demodulates the response wave signal, extracts card information, and passes it to the control unit 26. When there are a plurality of cards, the response wave signals are sequentially demodulated according to the time slot formed by the congestion control time Ti, and the card information is sequentially extracted and supplied to the control means 26. In step S26, the control unit 26 detects card information and temporarily stores it in the storage unit 25. Next, proceeding to (Step S27), the control means 26 searches the card information / response voice information table provided in the storage means 25 based on the temporarily stored card information, and corresponds to the card information. The response voice information is read, converted into a response voice signal, and output to the output means 27. The output unit 27 converts the supplied response voice signal into sound. Next, proceeding to (Step S28), by comparing the count value of the Tmax counter with the reception section information Tmax, it is determined whether or not the time Tmax has elapsed after the transmission of the burst reception wave, and the count value of the Tmax counter is If Tmax is exceeded, the process returns to (Step S20), and the card reader 20 transmits the next interrogation wave as a burst signal.

  An example of the card information / response voice information table stored in the storage means 25 is shown in FIG. The card information / response voice information table of FIG. 4 is a table in which response voice information indicating the corresponding card type is stored in order corresponding to the suit information and rank information constituting the card information. First, ace of spades, 2, 3 to 10, J, Q, K, then heart, diamond, club are stored in this order, and finally joker is stored. Each response voice information may be a digital voice sample string of words indicated by the card type, such as “Ace of Spades”, “Queen of Clubs”, and “Joker”. When the soot information and rank information of the card information are known, the control means 26 responds to the card information by searching the soot information column and the rank information column of this card information / response voice information table in (step S25). Response voice information can be obtained.

  Next, the interrogation wave signal, burst time length Tb, reception section information Tmax, response wave signal, congestion control time information Ti, and congestion control will be described. The congestion control time information Ti is standby time information until response wave transmission assigned to each card. If 53 cards are assigned numbers from i = 0 to 52 and the unit standby time is Td, the congestion control time information Ti is represented by Ti = i × Td. If i is assigned in the order of the card information in the card information / response voice information table shown in FIG. 4, the ace of spades is i = 0, so T0 = 0, and the spades 2 is i = 1. Since T = 0 = Td and spade 3 is i = 2, T0 = 2Td, and since the heart ace is i = 13, T0 = 13Td. Since the joker has i = 52, T52 = 52Td. Each card 10 generates a response wave signal and transmits a response wave at a timing shifted by the unit standby time Td. Therefore, when the time length of the response wave signal is Tr, if Tr <Td, the response waves of any card 10 do not overlap with the response waves of other cards 10 in time, and the response waves collide with each other. I don't get up. In any hand, the transmission of the response wave is completed during the time length = 53 Td. After transmitting the interrogation wave having the burst time length Tb, the card reader 20 does not transmit the next interrogation wave for the time of the reception section information Tmax at a minimum. Therefore, if Tmax> 53Td, the response wave of any card 10 does not collide with the next interrogation wave. If Td = 100 ms, Td = 5 ms, Tr = 3 ms, and Tmax = 500 ms, the card reader 20 can read the card information in the hand every 0.5 seconds. The response waves of a plurality of cards are transmitted in a time division manner in time slots divided every 5 ms within a time of 5 × 53 = 265 ms. Needless to say, these time values may be other values within the range of the above inequality condition.

  In (Step S25) of the flowchart of FIG. 3B, when there are a large number of hands, the process proceeds to (Step S26) after the output of those response voice signals is completed. It usually takes a time longer than Tmax to finish outputting the response voice signal. The next interrogation wave is transmitted after the game player hears the response voice signal of the entire hand. Accordingly, the response voice signal of the entire hand is not output, and the card information temporarily stored in the storage means 25 is not accumulated and continuously increased. Before transmitting the next interrogation wave, for example (step S26), it is preferable to delete the card information temporarily stored so far from the storage means 25.

  According to the present embodiment, when the congestion control time information Ti is allocated as described above, the order of the output response audio signals is the same even if the game player does not arrange the hand in the rank or suit order. First, the spades will be in the order of ace, 2, 3,..., J, Q, K, and then the heart hand, diamond hand, and club hand will follow. Therefore, the game player can easily understand and memorize the hand arrangement. In the card information / response voice information table, the ace may be positioned next to the king.

  The storage means 15 is preferably a nonvolatile recording medium made of a semiconductor. When a volatile recording medium is used, it is necessary to incorporate a battery in the card 10. The storage means 25 is preferably a non-volatile recording medium made of a semiconductor, but can also be realized using a volatile recording medium.

In each of the above embodiments, each component may be configured by dedicated hardware, or a component that can be realized by software may be realized by executing a program. For example, each component can be realized by a program execution unit such as a CPU reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory. In particular, the congestion control means 16 and the control means 26 are configured by a microprocessor and are suitable for being operated by a program. The rectifying unit 12, the demodulating unit 13, the modulating unit 14, the demodulating unit 23, and the modulating unit 24 can be configured by hardware such as a dedicated circuit.
In the flowchart of FIG. 3B, the card reader 20 may end the process by turning off the power or by interrupting the end of the process.

According to this embodiment, the game player can know the contents of the hand with the earphone 2 by sound. The game player listens to the sound of the earphone 2 and stores the card type of the hand, and determines whether there is a card of the same rank in the hand or whether the hand is played like poker according to the game. Is possible. If you forget the card type, want to reconfirm, or change your hand, etc., if you put your hand together and bring it close to the card reader 20 again, the card reader 20 will read out the hand type. Become. When choosing a discard card, the hand is brought close to the card reader 20 one by one, the card type is examined, and it is determined whether or not to discard it.
According to the present embodiment, not only the card information can be read for each card, but also the card information of a plurality of hand cards can be collected and read without missing.

  Card information for two or more interrogation waves is temporarily stored in response to the interrogation wave, and if the same combination of card information continues more than once, it is determined that the card information for all hands has been successfully acquired. Then, the response voice information may be read and a sound output may be performed.

If the hand is kept close to the card reader 20, each time the card reader 20 transmits an interrogation wave, the card reader 20 receives the card information from the card 10, and the card type of the hand is sounded. Inform. If the sound is noisy, the game player can stop reading by sound output if the hand is moved away from the card reader 20. In addition, when the sound output for the card information received within the time Tmax is completed and the card information is acquired by transmitting the next interrogation wave, whether the same card information is received compared with the previous card information temporarily stored If the control means 26 determines whether or not they are the same, the reading of the response voice information in (Step S27) may be stopped so that no sound is output.
(Embodiment 2)

In the card 10 according to the first embodiment, when the congestion time counter is omitted, when a plurality of cards 10 are brought close to the card reader 20, each card 10 transmits response waves almost simultaneously, so the card reader 20 May not read the card information correctly even if the response wave is received. In this case, the game player only needs to bring the cards 10 closer to the card reading device 20 one by one, read the card information, and know the card type. The control means 26 of the card reader 20 selects one response voice information corresponding to one card 10 from the card information / response voice information table, converts it into a response voice signal, and supplies it to the output means 27. become. When the congestion time counter is not provided as described above, the congestion control unit 16 does not perform the congestion control. Therefore, the congestion control unit 16 may simply be called the control unit 16. The card information is read from the storage unit 15 according to the instruction of the demodulation unit 13 and modulated. It suffices to have a function of a memory read circuit supplied to the means 14.
(Embodiment 3)

  In the present embodiment, the card reading device 20 is described in which it is determined whether or not cards of the same rank are included when a plurality of cards 10 are brought close to the card reading device 20, and the game player is notified. . A different part from Embodiment 1 is demonstrated.

  The storage means 25 has response voice signals “matched” and “not matched” as response voice information for rank match notification, and “ace”, “2”, “3”, It is assumed that 13 types of response voice information “Jack”, “Queen”, “King” and response voice information “I” are stored.

  In (step S26) shown in FIG. 3B, the control means 26 temporarily stores the transmitted card information in the storage means 25. In (step S27), the control means 26 reads the card information temporarily stored from the storage means 25, compares the card information, and checks whether there is card information with the matching rank information. When the card information matching the rank information is found, the control means 26 sets the response voice information “matching”, the response voice information corresponding to the matching rank information, and “is”. It is read from the storage means 25, converted into a response voice signal, and supplied to the output means 27. The output means 27 converts the supplied response voice signal indicating “appropriate” and rank and “is” into sound. The output means 27 causes the game player to hear a sound such as “It is correct. In (Step S27), when the control unit 26 cannot find the card information having the same rank information, the control unit 26 reads out the response voice information “not matched” from the storage unit 25, A response voice signal is converted and supplied to the output means 27. The output means 27 converts the supplied “not right” response voice signal into sound.

  In the case of a game in which two cards 10 having the same rank are searched from the playing field, such as a nervous breakdown game, the game player brings the two cards picked up from the playing field closer to the card reader 20, and the rank is the same. You can know if you are doing it.

  In the case of a blow-out game, when all the cards handed out first are brought close to the card reader 20, the output means 27 sends a response voice signal such as “matched, 2.3.5, jack, ace”. Output sound. You can know the rank names that have multiple cards in the same rank group. After starting the game, even if one card is taken from the next game player, if all cards including that card are brought close to the card reader 20, whether or not a matching card is obtained If you get a card to play, you will know what the rank is. After that, the hand is brought close to the card reader 20 one by one, and two matching rank cards are checked and specified, and are discarded in the field.

The storage means 25 stores response voice information for informing the number of sheets, such as “2 sheets”, “3 sheets”, “4 sheets”, and the like. You may make it output. The output means 27 outputs sound such as “matched. 2, 3, 3. 2, 2. 5. 2, 2. Jack. 2. Ace.”
(Embodiment 4)
Next, in the case of a poker game, a card reader 20 that can check the five cards in the hand to determine whether or not a hand is made and notify the game player will be described.
The role of poker is as follows in order of strength.
Five cards: 4 cards of the same number (rank) and Joker Royal Straight Flush: all 5 cards have the same suit, 10-A serial flash: 5 cards have the same suit and 5 cards.
Four cards: Four cards of the same number (rank) and the remaining one can be anything.
Full House: 3 cards of the same number (rank) and 2 cards of the same number (rank) in different cards.
Flash: Same as all five suits Straight: The suits are disjoint and have five consecutive numbers.
Three cards: There are three cards with the same number (rank). The other two sheets can be anything.
Two pairs: There are two sets of two (pairs) of the same number (rank). The remaining one can be anything.
One pair: There is only one pair. The remaining 3 cards can be anything.
No Pair: No use. Joker is almighty and can be used as a substitute for any card. The serial number means that 5 sheets are connected, such as 4, 5, 6, 7, and 8, for example. However, A and 2 are not connected. K and A are connected. If the role is the same, the pair (for example, four cards that are all in the case of four cards) with a larger number (rank) is stronger, and if the number (rank) is the same, the suit is Stronger is stronger. The strength of the suit is the order of spades, hearts, diamonds, and clubs. The full house will compare the three-disc set. If there are no winnings, it is better to have more spades with a higher rank, and with the same number, it is better to have a higher rank spade. If you don't have either, compare by heart. If there is no heart, compare with a diamond. If there is no diamond, compare at the club.

The card reader 20 in this embodiment has a block configuration similar to that of the block diagram shown in FIG. However, the storage means 25 is provided with a hand information table shown in FIG. The hand information table is constituted by a readable / writable storage element such as a RAM or a flash memory. Further, in the storage means 25, “Five Card”, “Royal Straight Flash”, “Straight Flash”, “Four Card”, “Full House”, “Flash”, “Straight”, which are used to notify the name of the role. , “3 card”, “two pair”, “one pair”, “no pair” response voice information and “card number is different” response voice information are stored. For this storage, it is preferable to use a nonvolatile storage element such as a ROM or a flash memory.
FIG. 5 is a flowchart showing an example of the processing procedure of the card reader 20 that determines the combination of the poker game.

  In the card reader 20, the interrogation wave is first transmitted intermittently in (Step S20) of FIG. The interrogation wave signal may be the same as that described in the first embodiment. (Step S21) to (Step S25) may be the same as described in the first embodiment. Next, proceeding to (Step S36), based on the received card information, the control means 26 indicates that there is a card in the row and column area corresponding to the rank and suit of the card information in the hand information table of the storage means 25. [1] is described and stored.

  An example of the hand information table is shown in FIG. The hand information table is a two-dimensionally arranged table corresponding to the 13 types of rank information and the 4 types of suit information in the card information. The rank information rows are in the order of 2, 3, 4,..., 12, 13, 1. Next, J rows are provided for the joker. A storage column for flash information F is provided on the bottom line. Corresponding to the soot information, four columns of S, H, D, and C are provided, followed by a storage column for the number information M column. [1] and [0] are stored in an area corresponding to 13 × 4 = 52 of 13 types of ranks and 4 types of soots. [1] indicates that there is a card of the suit and rank, and [0] is information indicating that there is no card of the suit and rank. When there is a joker, [1] is stored in the columns of S, H, D, C and the number information M in the J row. When there is no joker, [0] is stored. Therefore, if there is no joker, [1] is stored in 5 areas out of 13 × 4 = 52 areas of 13 rows and 4 columns of soot from rank 2 to rank 1 corresponding to ace. [0] is stored in the area. When there is a joker, [1] is stored in five areas of J rows, and a range of four rows of 13 rows and ranks from rank 2 to rank 1 corresponding to the ace, that is, 52 areas. Of these, [1] is stored in four areas, and [0] is stored in the remaining areas. The number information M stores the total number information of cards having the same rank. For this purpose, a numerical value obtained by adding [1] in columns S, H, D, and C may be stored as the number information M for each rank row. In the storage column of the flash information F, a numerical value obtained by adding [1] of each row from the rank 2 row to the J row for each soot column and the number information M column is stored.

  FIG. 8 is a hand information table when a full house is formed with two ranks 3 and three ranks 6. [0] is stored in an area not described. FIG. 9 is a hand information table in a case where a four card is made with a hand of rank 3 for spade and 4 for rank 13. FIG. 10 is a hand information table when one of rank 3, rank 6, rank 8, and rank 13 is a spade and a joker is used to flash. FIG. 11 is a hand information table when there is one each of rank 3, rank 4, rank 5, and rank 7 and the joker is regarded as rank 6 and becomes straight. By examining the flash information F row and the number information M column of the hand information table, it is possible to easily determine the role of poker.

  Next to the above (step S36) in the flowchart of FIG. 5, the control means 26 proceeds to (step S37) and determines whether there are five cards in the hand. Specifically, the control means 26 adds the numerical values in the number information M column of the hand information table and checks whether the sum is [5]. If the sum is not [5], the answer is No in (Step S37), and the control means 26 proceeds to (Step S36), reads the response voice information “The number of cards is different” from the storage means 25, and converts it into a response voice signal. And supplied to the output means 27. If the sum is [5], the answer is Yes in (Step S37), the control means 26 proceeds to (Step S39), counts the number of [1] for each row and column of the hand information table, and the number information M and the flash Information F is generated and stored. Next, the control means 26 proceeds to (Step S40), and determines the role of the poker game based on the number information M, the flash information F, and the joker information. Next, the control means 26 proceeds to (Step S41), reads out the response voice information corresponding to each card information and combination of the five cards, converts it into a response voice signal, and supplies it to the output means 27. Next, the control means 26 proceeds to (Step S42), deletes the stored contents of the hand information table, and returns to (Step S20).

  6 and 7 are examples of detailed processing procedures of (Step S40) and (Step S41). In step S61, the control means 26 reads the J line of the hand information table and checks for the presence of a joker. In the case of Yes, the control means 26 proceeds to (Step S90) in FIG.

  In the case of No in (Step S66), the control means 26 proceeds to (Step S67), and checks whether there are five sequential numbers in the number information M row. Five sequential numbers mean that there are five cards with consecutive ranks. Specifically, the control means 26 examines the number information M column from the top row, and when the number information M for five rows from the first non- [0] row is all [1], it is determined that there are five sequential numbers. . If the fifth serial number is Yes (step S68), the process proceeds to step S68 to check whether there is [5] in the soot information column of the flash information F row. In No, it progresses to (step S76), the response audio | voice information of "straight" is read, converted into a response audio | voice signal and output.

  In the case of Yes in (Step S68), the control means 26 proceeds to (Step S69), and checks whether the sheet number information M has five sequential numbers of 10, 11, 12, 13, 1. In No, it progresses to (step S77), the response audio | voice information of "straight flash" is read, converted into a response audio | voice signal and output. In the case of Yes in (Step S69), the control means 26 proceeds to (Step S78), reads the response voice information of “Royal Straight Flash”, converts it into a response voice signal, and outputs it.

  In the case of No in (Step S67), the control means 26 proceeds to (Step S70) and checks whether [5] is present in the soot information column of the flash information F row. In the case of Yes, the process proceeds to (step S79), the response voice information of “flash” is read, converted into a response voice signal, and output. In the case of No in (Step S70), the control unit 26 proceeds to (Step S80), reads the response voice information of “no role”, converts it into a response voice signal, and outputs it.

  In each of the above processing steps, after the response voice information is read out, converted into a response voice signal and output, the control means 26 proceeds to (Step S42) in FIG. 5 and erases the stored information in the hand information table. [0] is set in the field of (2), and the process returns to (Step S20).

  In (Step S61) in FIG. 6, if Yes, there is a joker, and the control means 26 proceeds to (Step S90) in FIG. 7, and checks whether there is only one [2] in the number information M column. . If Yes, the process proceeds to step S98, and the response voice information of “three cards” is read, converted into a response voice signal, and output.

  In the case of No in (Step S90), the control means 26 proceeds to (Step S91) and checks whether there are two [2] s in the number information M column. If Yes, the process proceeds to step S99, and the response voice information of “full house” is read, converted into a response voice signal, and output.

  In the case of No in (Step S91), the control means 26 proceeds to (Step S92) and checks whether [3] is in the number information M row. If Yes, the process proceeds to step S100, and the response voice information of “four cards” is read, converted into a response voice signal, and output.

  In the case of No in (Step S92), the control means 26 proceeds to (Step S93) and checks whether [4] is present in the number information M row. If Yes, the process proceeds to step S101, and the response voice information of “Five Card” is read, converted into a response voice signal, and output.

  In the case of No in (Step S93), the control means 26 proceeds to (Step S94), and checks whether there are four consecutive numbers in the number information M row. The 4-sequential number means a case where there are four cards with consecutive ranks, or a case where there is no card at any one of the five consecutive ranks. Specifically, the control means 26 checks the number information M column from the top row, checks the number information M for five rows from the first non- [0] row, and includes four [1]. It is determined that the serial number is four. If the fourth sequential number is Yes, the control means 26 proceeds to (Step S95) and checks whether there is [5] in the soot information column of the flash information F row. In the case of No, the control means 26 proceeds to (Step S102), reads the response voice information of “straight”, converts it into a response voice signal, and outputs it.

  In the case of Yes in (Step S95), the control means 26 proceeds to (Step S96), and whether or not the number information M is four consecutive numbers including four ranks among the five ranks 10, 11, 12, 13, 1. Investigate. In the case of No, the control means 26 proceeds to (Step S103), reads the response voice information of “straight flash”, converts it into a response voice signal, and outputs it. In the case of Yes in (Step S96), the control means 26 proceeds to (Step S104), reads the response voice information of “Royal Straight Flash”, converts it into a response voice signal, and outputs it.

In the case of Yes, the control means 26 proceeds to (Step S105), reads the response voice information of “flash”, converts it into a response voice signal, and outputs it. In the case of Yes in (Step S97), the control means 26 proceeds to (Step S106), reads “one pair” response voice information, converts it into a response voice signal, and outputs it.

  In each of the above processing steps, after the response voice information is read out, converted into a response voice signal and output, the control means 26 proceeds to (Step S42) in FIG. 5 and erases the stored information in the hand information table. [0] and return to (step S20).

  Next, after the processing of (Step S42), the control means 26 compares the count value of the Tmax counter with the reception interval information Tmax as shown in (Step S28) of FIG. It is determined whether the time Tmax has elapsed. If the count value of the Tmax counter exceeds Tmax, the process returns to (Step S20), and the card reader 20 transmits the next interrogation wave as a burst signal. However, since the time for outputting each response voice signal is usually longer than Tmax, the count value of the Tmax counter exceeds Tmax when (Step S42) is completed. Therefore, it is not usually necessary for the control means 26 to execute (Step S28).

In addition to the names of the above-mentioned roles, response voice information of soot names and rank names is stored in the storage means 25, and in addition to the names of roles, soot names and response voice signals of rank names are output. You may make it do. “4 Two Pairs”, “Heart Flash” and so on.
Further, the hand information table shown in FIG. 8 is an example, and other types of tables may be used as long as the card information of the hand can be stored and the card information can be stored.
(Embodiment 5)

  Next, the card reader 30 for the place tag shown in FIG. 1 will be described. The card reader 30 basically has the same block configuration as the card reader 20 described with reference to FIG. As the output means 27, the earphone 2 is not used but a speaker is used. The speaker allows all game players to hear the sound of the response audio signal corresponding to the card information. The operation of the card reader 30 may be the same as that described in the first and second embodiments. It is only necessary to read the card information of one or a plurality of place cards or discard cards 10 and output the sound of the response voice signal. The card reader 30 using a speaker is effective for informing a visually impaired person of the type of the card when a visually impaired person puts out a place tag or discards it.

If a visually-healthy person participates in the game, if the visually-healthy person reads the place tag or discard tag by voice and informs the visually handicapped person, the card reader 30 for the place tag may be omitted. , Visually healthy people may not be able to concentrate on the game. If the card reader 30 for a place tag is used, such a concern is eliminated.
(Embodiment 6)
As described above, the processing procedure of the card reader 20 described in each of the above embodiments may be configured by a program.

  2B, a wireless LAN terminal device and an interface device with a personal computer such as a USB are added to the configuration of the card reader 20, and the processing procedure program and response voice information of the card reader 20 are transmitted to the wireless LAN server. The control means 26 stores the program of the processing procedure of the card reader 20 and the response voice information from the server or personal computer via the wireless LAN terminal device or an interface device with a personal computer such as USB. And may be stored in the storage means 25.

Since the processing procedure program and response voice information of the card reader 20 can be rewritten, when a new game is devised and provided via a wireless LAN server, CD-ROM, the Internet, etc., the card reader 20 It becomes possible to correspond to the game.
(Embodiment 7)
In each of the above-described embodiments, the case where a system generally called a passive system is applied as an RF tag system has been described as an example, but an active system may be applied.

That is, a small battery is embedded in each card so that the card spontaneously transmits the same radio wave as the response wave. In this case, the card 10 may not include the demodulating unit 13, and the card reader 20 may not include the modulating unit 24. As a power source embedded in the card, a piezoelectric ceramic element is used instead of the battery. When the card is shuffled, the card is bent several times to generate electric power in the piezoelectric ceramic element, and the generated electric charge is rectified by the rectifier 12. The capacitor may be charged and used as a power source. What is necessary is just to have a power supply capacity of about one game time. The congestion control means 16 has a function of detecting a case where its own response wave collides with a response wave of another card and retransmitting the response wave. The question wave does not have to be used.
(Other embodiments and supplements)

Although the card reader 20 has been described for use in a breast pocket, it may be hung around the neck like a pendant. The card reader 20 may be used on a desk. Moreover, you may use it in your hand. It may be in the form of a ring. However, it goes without saying that it is not used to read another player's hand during the game.
In the flowcharts of FIGS. 3B and 5, the card reader 20 may end the process by turning off the power or by interrupting the end of the process.

  The storage means 15 is preferably a nonvolatile recording medium made of a semiconductor. When a volatile recording medium is used, it is necessary to incorporate a battery in the card 10. The storage means 25 is preferably a non-volatile recording medium made of a semiconductor, but can also be realized using a volatile recording medium.

  In each of the above embodiments, each component may be configured by dedicated hardware, or a component that can be realized by software may be realized by executing a program. For example, each component can be realized by a program execution unit such as a CPU reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory. In particular, the congestion control means 16 and the control means 26 are configured by a microprocessor and are suitable for being operated by a program. The rectifying unit 12, the demodulating unit 13, the modulating unit 14, the demodulating unit 23, the modulating unit 24, and the output unit 27 can be configured by hardware such as a dedicated circuit.

  In the description of each of the above embodiments, the interrogation wave is a burst signal, and the falling point is used as activation instruction information to the congestion control means 16. The interrogation signal is transmitted by superimposing the activation instruction code information indicating the activation instruction, and the demodulation unit 13 demodulates the interrogation wave signal, extracts the activation instruction code information, and supplies it to the congestion control unit 16. Also good.

  Even after the activation instruction code information is superimposed on the interrogation wave and transmitted, the interrogation wave without the activation instruction code information may be continuously transmitted to supply power to the card 10. Since the response wave normally uses the same carrier frequency as that of the interrogation wave, even if the interrogation wave and the response wave collide with each other, only the carrier frequency is enhanced in the received radio wave at the card reader 20, and the response wave signal Can be demodulated.

  The congestion control time Ti information is different for each of the 53 cards. The card reader 20 may count the elapsed time up to the time when the response wave is received after the transmission of the interrogation wave, determine the card type based on the elapsed time, and convert it to card information. The congestion control time Ti information corresponds to the card information.

  If the transmission power of the interrogation wave or response wave is too strong, card information such as the hand or deck of the adjacent game player is read out. The transmission power of the interrogation wave and the response wave and the reception sensitivity of the demodulating means 13 and the demodulating means 23 are designed so that they can communicate within a distance of about 3 cm to 5 cm, and cannot communicate when they are separated from 10 cm to 20 cm or more. Most preferred. However, the numerical values of these distances are not essential conditions.

The card information described in the above embodiment is an example, and may be other than the form described in the above embodiment. The card information / response voice information table, hand information table, etc. may be in other formats. The flowcharts of FIGS. 3A, 3B, 5, 6, and 7 are examples, and the procedure may be modified.
When the card information of a plurality of hands is read and sound is output, the card information may be determined according to the game rules and the sound output according to the game rules may be performed.

  The card and the card reader of the present invention can be applied to cards other than the card game, for example, card games such as flower cards, karuta, and UNO. The number of cards and the type of card differ for each card game. In Hanafuda, card information may be assigned for each picture. In UNO (Uno), corresponding to the card colors, numbers, draw two (draw to), reverse (reverse), skip (skip), wild (wild), draw four (draw for), What is necessary is just to assign card information.

  As the card information, numbers and codes may be sequentially assigned to all cards, and the card readers 20 and 30 may convert the numbers and codes into group information. The group information referred to here is information for identifying the same type of group by the design, number, color, etc. of the card, and in the case of playing cards, the above-mentioned soot information, rank information, and joker information.

  Game identification code information for identifying flower cards, karuta, UNO, etc. is determined and transmitted by superimposing it on the interrogation wave signal or response wave signal. May be demodulated to prevent the card reader 20 from malfunctioning. Further, the card readers 20 and 30 incorporate not only playing cards but also a card determination function and a card reading function corresponding to other card games, and demodulate the game identification code information to read the card for the corresponding card. A function may be selectively activated.

  An operation unit such as a switch is added to the configuration of the card reading device 20 shown in FIG. 2B, and the control unit 26 detects the state of the operation unit and controls the operation of the card reading device 20. May be. As the operation means, a question wave transmission button may be provided, and the control means 26 may monitor whether this button is pressed and transmit a question wave when the button is pressed. A card game selection switch is added, and the state of the selection switch is checked by the control means 26 and selected from a plurality of game processing programs for playing cards stored in the storage means 25 to determine card information. It may be. A selection switch such as a playing card, flower card, karuta, or UNO is additionally provided, and the card information is determined by selecting from a plurality of game processing programs stored in the storage means 25. Good.

  Information other than activation instruction code information may be added to the interrogation wave signal, and information other than card information may be added to the response wave signal. An error correction code may be added to information such as card information and activation instruction code information for transmission, and at the time of reception, error correction processing may be performed to improve the reliability of information communication.

  When a plurality of response waves collide, the card 10 itself detects the collision of the response waves and resends the response wave, or the card reader 20 detects the collision and informs the card 10 of the collision. It is also possible to perform congestion control such as retransmitting Such congestion control technology is well known in wireless LAN technology and the like and will not be described in particular.

  The RF tag for the card 10 described with reference to FIG. 2A can be realized as a semiconductor IC chip with an antenna 11. The RF tag may be attached to the surface of the card, or may be embedded in the card sheet. When the card is made of paper, the RF tag may be inserted into the paper. Note that some RF tag systems are standardized as standards such as ISO, but when used in the present invention, it is sufficient to use extremely weak radio waves. It may or may not be. 2A, a wireless transmission / reception circuit that is not called an RF tag may be used.

  As a basic technology related to RF tags, the method of transmitting and receiving interrogation waves and response waves is based on electromagnetic coupling between two antennas, in addition to a method of performing communication or broadcasting using ordinary radio waves. There are also known methods for transmitting and receiving information by causing them to cause electromagnetic induction, and such methods may be applied. The transmission and reception of interrogation waves and response waves and the transmission and reception of radio waves of interrogation waves and response waves in the above embodiments of the present invention include transmission and reception of information by electromagnetic coupling and electromagnetic induction. The modulation means 14 includes an impedance variable circuit for changing the state of electromagnetic coupling or electromagnetic induction. Transmitting a response wave includes a case in which the response wave is generated in the interrogation wave by changing the impedance in the antenna 11 in a state where the interrogation wave is transmitted. The card information is transmitted to the demodulator 23 of the card reader 20 in the form of a change in the amplitude of the interrogation wave.

When a plurality of cards 10 are aligned and brought close to the card reader 20, the RF tags inside the cards 10 are overlapped, and the card close to the card reader 20 may be a shield against a far card. What is necessary is just to approach the card reader 20 without arranging the cards 10. Further, if the position for embedding the RF tag for each card is shifted, the risk of shielding each other even if the cards 10 are aligned is reduced. If a large number of cards 10 are brought close to the card reader 20, the power of the interrogation wave is insufficient, and there is a possibility that sufficient power cannot be supplied to each card 10. While the modulating means 24 is outputting the interrogation wave, the demodulating means 23 monitors the level of the interrogating wave output from the modulating means 24, and notifies the control means 26 if the level is lower than a predetermined value. The control means 26 may instruct the modulation means 24 to increase the output level of the interrogation wave.
Braille information indicating the card type may be provided on the front surface or the back surface of the card of the present invention. Normally, it should be provided on the surface of the card so that it cannot be seen by a visually healthy person.
The card readers 20 and 30 of the present invention may be incorporated in a notebook computer, PDA, mobile phone, wireless LAN card, or the like.
It should be noted that the card and card reader of the present invention can be used for game learning by players who are unfamiliar with the game, even if they are visually impaired.
The present invention is not limited to the embodiments described above, and various modifications are possible, and it goes without saying that these are also included in the scope of the present invention.

  As described above, the card and the card reader according to the present invention enable smooth game progress when a visually impaired person plays a card game, for example, so that the visually impaired person can use the personally. It can also be used in facilities for the visually impaired. Moreover, even a visually healthy person can be used for beginners of the game.
