  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

(First embodiment: wireless information communication system)
The wireless information communication system using NFC in the present embodiment is a system in which a user terminal held by a user and a wireless objective device provided in a tangible object perform data communication in a contactless manner within a distance of 10 cm or less. The NFC has an RF carrier frequency of 13.56 MHz and a maximum communication speed of 212 Kbps.

  FIG. 1 is an explanatory diagram schematically showing such a wireless information communication system.

  In FIG. 1, a user 110 has a mobile phone as a user terminal 112 and is about to obtain information on a communication purpose device 116 attached to a poster as a tangible object 114.

  The user terminal 112 has a switch for obtaining information from the communication target device 116 or for providing information to another communication target device. By the arrangement of the user terminal 112 and the operation of the switch, the communication target device Data communication with 116 is performed.

  The tangible object 114 is any object including public objects such as advertisements, posters, bulletin boards, signboards, and the like. Conventionally, the user 110 confirms the data directly from such an information source and notes it in a notebook or the like. It was.

  The communication purpose device 116 is attached to the tangible object 114 and communicates with the user terminal 112 within a predetermined range. The communication purpose device 116 can be formed in various shapes. In this embodiment, the communication purpose device 116 is formed in a thin card shape and is attached to the front or back of a tangible object. Further, the communication purpose device 116 is battery-less and receives power supply energy by radio waves from the user terminal 112.

  In such NFC, since communication is performed in a non-contact manner only within a narrow range, it is possible to easily grasp and recognize a communication purpose device intended for communication by the user's vision, and perform easy-to-understand communication processing by hand action. it can. For example, in FIG. 1, the communication range 120 of the communication target device 116 does not overlap with the communication range 124 of the other communication target devices 122, and the user 110 communicates with the communication target device 116 reliably and safely. obtain.

  As a method for performing such non-contact wireless communication, there are an infrared method (IrDa: InfraRed Data Association), Bluetooth, a QR code obtained by two-dimensionalizing a barcode, and the like.

  However, since IrDa is a communication using light components, there is a problem that it is difficult to use it outdoors under direct sunlight. In addition, infrared rays have directivity, but are not limited to a predetermined range as in the present NFC. Therefore, when there are a plurality of IrDa light receiving units in the same direction, an unintended device may react. In addition, infrared rays may cause communication with an unintended device due to reflections in the same direction, leaving concerns about safety. Furthermore, in infrared rays, it is difficult to transmit power using a carrier wave, and a configuration having a power source is unavoidable, and there are problems in terms of cost and versatility.

  In addition, the above Bluetooth requires a complicated menu operation for connection and has a wide communication range, so it is not suitable for selecting a target by hand action. In such a communication system that assumes a long distance, it is difficult to transmit power using radio waves.

  In addition, with QR codes, it is necessary to use image recognition by a visual recognition device, and difficulties such as positioning remain. Furthermore, it cannot be used in an invisible state, for example, in the dark. In addition, barcodes that become dirty due to outdoor use can cause problems that generate incorrect information.

  As described above, in the present embodiment, a short communication distance has a new effect that other communication methods do not have.

(Second embodiment: user terminal 112)
FIG. 2 is a block diagram showing the configuration of the user terminal 112 used in the wireless information communication system.

  The user terminal 112 includes a user antenna unit 210, a user NFC function unit 212, a user data storage unit 214, an input unit 216, a data reading unit 218, a data writing unit 220, a status display unit 222, an error The display unit 224 includes a display unit 224 and a user format conversion unit 226.

  The user antenna unit 210 is an antenna for communicating with the communication target device 116, and an electric signal from the user terminal 112 is converted into a radio wave signal, and a radio wave signal from the communication target device 116 is converted into an electric signal. Convert. The length and shape of the antenna are determined according to the RF carrier frequency of 13.56 MHz in NFC.

  The user NFC function unit 212 is formed in the NFC semiconductor chip 228 and plays a central role in NFC communication processing for the purpose of short-range communication. The user NFC function unit 212 includes a signal processing circuit that processes a signal transmitted / received by NFC and a modulation / demodulation circuit for converting the signal into RF (Radio Frequency).

  The user data storage unit 214 stores data used by the user terminal 112 and also stores communication data with the communication target device 116. As a medium for storing data, a non-volatile memory or a volatile memory is used, and is provided in the NFC semiconductor chip 228 together with the user NFC function unit 212.

  The input unit 216 includes at least one switch, but can be shared with an input unit used for functions other than the present embodiment in the user terminal 112. For example, the mobile phone as the user terminal 112 in the present embodiment is provided with a group of input buttons for inputting a telephone number and text of an e-mail, and one of them can be used in the present embodiment. In addition, since many switches are not required, the mobile phone can be placed at a position where it can be easily pushed with the thumb or forefinger while the mobile phone is supported by the user's hand.

  The data reading unit 218 reads target data from the communication target device 116 via the user NFC function unit 212 in accordance with an operation of the input unit 216 and stores it in the user data storage unit 214.

  The data writing unit 220 transmits the data stored in the user data storage unit 214 to the communication target device 116 via the user NFC function unit 212 according to the operation of the input unit 216.

  The status display unit 222 has a function of visually or audibly informing when the target data is read or during data writing. For example, the fact that it is operating is displayed by the LED or LCD of the user terminal 112. At this time, in the case of LED, it can be confirmed by the lighting color and lighting state (off, blinking, lighting), and in the case of LCD, it can be confirmed by the display background color, display comment, and the like.

  The error display unit 224 measures the time required for reading the target data or writing the stored data, and displays an error on the status display unit 222 when it is not performed within a predetermined time. . The display format follows the status display unit 222 described above. For example, in reading the data, when the communication processing is started by placing the user terminal 112 on the communication target device 116, the LED as the status display unit 222 changes from the off state to the lit state, and the data reading of the user terminal 112 is completed. Then, it returns to the off state. If the data reading of the user terminal 112 fails due to some cause (for example, when it becomes impossible to maintain the communication distance), the LED changes to blinking according to the configuration of the error display unit 224.

  The user format conversion unit 226 can process data when the data read from the communication target device 116 or the data format of data written to the communication target device 116 cannot be processed by the user NFC function unit 212 of the user terminal 112. Has a function to convert to a format. Such data formats are TEXT, RICH_TEXT, ASCII, EUC, JIS, BMP, JPEG, MPEG, GIF, TIFF, and the like, and it is possible to respond to a plurality of data formats that cannot be processed.

(Third Embodiment: Communication Purpose Device 116)
FIG. 3 is a block diagram showing the configuration of the communication purpose device 116 used in the wireless information communication system.

  The communication target device 116 includes a target antenna unit 310, a target NFC function unit 312, a target data storage unit 314, a data output unit 316, a data input unit 318, a lock function unit 320, and a target format conversion unit 322. And a lock switch 326.

  The target antenna unit 310 is an antenna for communicating with the user terminal 112, and converts an electric signal from the communication target device 116 into a radio wave signal, and converts a radio wave signal from the user terminal 112 into an electric signal. To do. The length and shape of the antenna are determined according to the RF carrier frequency of 13.56 MHz in NFC.

  The purpose NFC function unit 312 is formed in the NFC semiconductor chip 324 and plays a central role in NFC communication processing for the purpose of short-range communication. The objective NFC function unit 312 includes a signal processing circuit that processes a signal transmitted and received by NFC and a modulation / demodulation circuit for converting the signal into RF (Radio Frequency).

  The target data storage unit 314 stores data used by the communication target device 116 and also stores communication data with the user terminal 112. As a medium for storing data, a non-volatile memory or a volatile memory is used, and is provided in the NFC semiconductor chip 324 together with the target NFC function unit 312.

  The data output unit 316 outputs the data stored in the target data storage unit 314 to the user terminal 112 via the target NFC function unit 312 in response to a request from the user terminal 112.

  The data input unit 318 stores data input from the user terminal 112 via the target NFC function unit 312 in the target data storage unit 314 in response to a request from the user terminal 112.

  The lock function unit 320 can prohibit the output and / or input of data with the user terminal 112 according to a user setting. Since the communication objective device 116 operates in response to an instruction from the user terminal 112, there is a possibility that data will be manipulated against the will of the user of the communication objective device 116. Such operation can be restricted by the lock function unit 320. In this case, the communication with the user terminal 112 is restricted by pressing a means for enabling the lock function unit 320 provided in the communication purpose device 116, for example, the lock switch 326. Such a restriction prevents leakage of personal information in a crowded train, for example.

  The target format conversion unit 322 is a data format that can be processed when the data format of data read from the user terminal 112 or data to be written to the user terminal 112 cannot be processed by the target NFC function unit 312 of the communication target device 116. It has a function to convert to. Such data formats are TEXT, RICH_TEXT, ASCII, EUC, JIS, BMP, JPEG, MPEG, GIF, TIFF, and the like, and it is possible to respond to a plurality of data formats that cannot be processed.

  Further, since the communication purpose device 116 is assumed to be placed in any place, it may be configured without a battery. The communication purpose device 116 configured in this manner without a battery normally stands by in a sleep state, and when a communication request is received from the user terminal 112, the user uses the energy from the radio waves obtained from the user terminal 112 as a power source. It operates according to the terminal 112.

(Fourth embodiment: user terminal 112, communication purpose apparatus 116)
FIG. 4 is a block diagram in the case where the user terminal 112 and the communication purpose device 116 described above are configured as one device. Here, the function of the communication target device 116 is formed by being included in the user terminal 112.

  In the user terminal 112, a lock function unit 320 is added to the user terminal 112 described in the second embodiment. The user data storage unit 214 also functions as a target data storage unit 314, and the data reading unit 218 and the data writing unit 220 serve as both the data input unit 318 and the data output unit 316. Furthermore, the lock switch 326 that is an input means to the lock function unit 320 in the communication purpose device 116 is substituted by the input unit 216 of the user terminal 112.

  Each component described above has substantially the same function as the component described in the second and third embodiments, so that the duplicate description is omitted.

  As described above, by integrating the functions of the user terminal 112 and the communication purpose device 116, various usage methods can be realized. The difference in operation between the user terminal 112 and the communication purpose device 116 is that when data is actively written and read, the user terminal 112 functions as the user terminal 112 and passively from another device (for example, another user terminal). When data is written or read, it functions as the communication purpose device 116. As described above, the user NFC function unit 212 operates as the user terminal 112 or as the communication purpose device 116 depending on which of the communication partners has started communication.

(Fifth embodiment: wireless information communication method)
FIG. 5 is an explanatory diagram showing the wireless information communication method in the present embodiment in detail, and particularly shows writing of data from the user terminal 112 to the communication target device 116.

  Writing from the user terminal 112 to the communication target device 116 is performed by the user terminal 112 within the predetermined range from the write data selection step S500 for selecting data to be written to the communication target device 116 at the user terminal 112. The user terminal arrangement step S502 for sending data to the communication target device 116, and the data writing step S504 for writing the data selected in the write data selection step S500 to the communication target device 116 in accordance with the operation of the input unit of the user terminal 112. And made from.

  In the present embodiment, a mobile phone is used as the user terminal 112, and a personal computer (hereinafter abbreviated as a personal computer) is used as the communication purpose device 116 to which data is written.

  First, the cellular phone is activated and data to be written into the personal computer is selected (S510).

  FIG. 6 is a structural diagram specifically showing the selection (S510) in the mobile phone as the user terminal 112. In such a case, the telephone number and address of the store “THE STORE” are selected from the data stored in the user data storage unit 214 of the mobile phone. Here, the data of the store “THE STORE” is displayed on the display unit 554 by using the cross key 550 and the button group 552, and the telephone number and address part are designated by the reverse display 556.

  Next, the cellular phone is brought close to the personal computer, and the cellular phone is put on the target antenna unit 310 as the communication purpose device 116 of the personal computer (S512).

  FIG. 7 is a structural diagram specifically showing the above step (S512) in the personal computer as the communication purpose device 116. In FIG. In such a case, the user terminal 112 is placed within a predetermined range 572 of the target antenna unit 310 provided on the keyboard 570 of the personal computer.

  Next, when the NFC switch 558 of the cellular phone shown in FIG. 6 is pressed (S514), the user NFC function unit 212 provided in the cellular phone requests the personal computer to transmit a data format list (S516). At this time, the mobile phone continues to output RF and waits for a response from the personal computer. If there is no response for a predetermined time, for example, 5 seconds, an error is output by the error display unit 224.

  The NFC semiconductor chip 228 of the personal computer starts its operation by obtaining energy from radio waves from its own power supply or mobile phone. A plurality of data formats that can be processed by a personal computer in response to a transmission request for a data format list from a mobile phone, or that can be processed after the data format is converted by a target format conversion unit 322 provided in the personal computer. A data format list is prepared (S518), and the data format list is transmitted to the mobile phone (S520).

  Subsequently, the user selects an optimum data format from the data format list on the mobile phone (S522). For example, if the data to be transmitted is character string data and “TEXT” and “RICH_TEXT” are selected in the data format list, “RICH_TEXT” can be selected based on the processing after transmission to the personal computer. . In this case, the data format of the data stored in the mobile phone can be transferred by RICH_TEXT as text characters in a “century” bold font.

  If the data format of the data to be transmitted is not in the data format list received from the personal computer, it can be converted to the data format in the data format list. For example, if a personal computer presents a BMP data format and a JPEG data format and the mobile phone has image data in the GIF data format, the mobile phone converts the image data from the GIF data format to the JPEG data format.

  Since the selection of the data format depends on the mobile phone as the user terminal 112 and the selection procedure is standardized to some extent, a priority order to be selected in advance is set, and the user NFC of the mobile phone is set according to this priority order. The function unit 214 can automatically select the data format from the data format list. For example, if “TEXT” and “RICH_TEXT” are displayed in the data format list and the priority of data format selection is set to “1.RICH_TEXT” or “2.TEXT”, “RICH_TEXT” is automatically selected. The In such a case, the selection by the user in S522 can be omitted, and only the NFC switch 558 is pressed (S514), and this process is automatically performed.

  Subsequently, data having the data format thus selected is transmitted to the personal computer (S524). The personal computer that has received the data converts the data into a data format that can be processed by the personal computer as required (S526).

(Sixth embodiment: wireless information communication method)
FIG. 8 is an explanatory diagram illustrating the wireless information communication method in the present embodiment in detail, and particularly represents reading of data from the communication target device 116 in the user terminal 112.

  The user terminal 112 reads data from the communication target device 116 within the predetermined range from the communication target device 116 by placing the user terminal 112 over the communication target device 116 and the input unit of the user terminal 112. In response to the operation 216, the data reading step S602 reads data stored in the communication target device 116.

  Also in this embodiment, a mobile phone is cited as the user terminal 112, and a personal computer is cited as the communication purpose device 116 to which data is to be written.

  First, data to be read by the personal computer is selected (S610). As in the fifth embodiment, this selection is performed by designating the data stored in the personal computer by reverse display using a cross key or a mouse.

  Next, the activated mobile phone is brought close to the personal computer, and the mobile phone is put on the target antenna unit 310 as the communication target device 116 of the personal computer (S612).

  Subsequently, when the NFC switch 558 of the cellular phone is pressed (S614), a transmission request for a data format list consisting of data format groups is transmitted from the cellular phone to the personal computer (S616). At this time, the mobile phone continues to output RF and waits for a response from the personal computer. If there is no response for a predetermined time, for example, 5 seconds, an error is output by the error display unit 224.

  The NFC semiconductor chip 228 of the personal computer starts its operation by obtaining energy from radio waves from its own power supply or mobile phone. A plurality of data that can be transmitted after the data format is converted by the target format conversion unit 322 provided in the personal computer or in accordance with the transmission request of the data format list from the mobile phone. A data format list indicating the format is prepared (S618), and the data format list is transmitted to the mobile phone (S620).

  Subsequently, the user selects an optimum data format from the data format list on the mobile phone (S622). For example, if the data to be received is character string data and “TEXT” and “RICH_TEXT” are selected in the data format list, the data format that can be processed by the mobile phone is effectively used, and “RICH_TEXT” It is possible to choose. Here, the data format of the data stored in the personal computer can be received by RICH_TEXT as a text character in a “Cold” bold font.

  If the data format of the receivable data is not in the data format list received from the personal computer, the data format in the data format list can be converted to a data format that can be processed in the personal computer. For example, if the personal computer presents the BMP data format and the JPEG data format and the mobile phone can only process the image data in the GIF data format, the mobile phone receives the image data in the JPEG data format, and then the user format. The conversion unit 226 converts the data into the GIF data format.

  Since the selection of the data format depends on the mobile phone as the user terminal 112 and the selection procedure is standardized to some extent, a priority order to be selected in advance is set, and the user NFC of the mobile phone is set according to this priority order. The function unit 214 can automatically select the data format from the data format list. For example, if “TEXT” and “RICH_TEXT” are displayed in the data format list and the priority of data format selection is set to “1.RICH_TEXT” or “2.TEXT”, “RICH_TEXT” is automatically selected. The In such a case, the selection by the user in S622 can be omitted, and only the NFC switch 558 is pressed (S614), and this process is automatically performed.

  The data format thus selected is transmitted to the personal computer (S624). The personal computer that has received the data converts the data in the personal computer into the received data format as necessary via the target format conversion unit 322 (S626), and transmits the data in the data format to the mobile phone (S628). ). If the personal computer already has the data of the selected data format, it is not necessary to change the data format, so the step of S626 is omitted.

(Seventh embodiment: wireless information communication method)
FIG. 9 is an explanatory diagram showing the wireless information communication method in the present embodiment in detail. In particular, data is copied from the communication target device 116 to another communication target device 650 via the user terminal 112.

  In the present embodiment, a mobile phone is used as the user terminal 112, and a personal computer is used as the communication purpose devices 116 and 650 to be written.

  Conventionally, such partial data and files have been transferred using a data storage medium or a wired link. However, in this embodiment, it is easy regardless of the compatibility of the storage media of both communication target devices 116 and 650 and the presence or absence of connection lines. Data can be transferred to
