  The remote control CPU 203 transmits information from the server acquired from the set CPU 205 to the remote controller 100 by the short-range wireless communication described above, and reads and writes information to and from the IC card via the CPU 103 of the remote controller 100. That is, reading and writing of information with respect to the IC card performed by the reader / writer 106 of the remote controller 100 is controlled by a command received by the television receiver 200.

  Note that the television receiver 200 may further include a large-capacity rewritable HDD (Hard Disc Drive) or the like, and may record the moving image content desired by the user in this memory.

  Next, a communication operation between the remote controller 100 and the television receiver 200 in the communication system 1 will be described.

  When the user operates an operation key arranged on the key operation unit 105 of the remote controller 100, the CPU 103 determines that an operation command has been input, and sends it to the television receiver 200 via the RF transmission / reception unit 102 and the antenna 101. Send the corresponding instruction.

  In the television receiver 200, the remote control CPU 203 determines a command acquired via the antenna 201 and the RF transmitter / receiver 202 and performs control processing corresponding to the command.

  When a user intends to purchase contents such as movies, animations, dramas, sports, and games from the Internet, he / she purchases by performing necessary operations with the remote controller 100 while viewing the operation screen displayed on the television receiver 200. Select and determine content. When the user decides the content payment method using the IC card and pays the purchase price, the remote control CPU 203 of the television receiver 200 controls the remote control by the above-mentioned short-range wireless communication via the RF transceiver 202 and the antenna 201. Information to communicate with the IC card is transmitted to 100. The CPU 103 of the remote controller 100 turns on the power of the reader / writer 106, generates electromagnetic waves necessary for reading and writing of the IC card from the antenna 107, and reads information recorded on the IC card. Information read from the IC card is transmitted to the television receiver 200 via the RF transceiver 102 and the antenna 101.

  The television receiver 200 transmits information read from the IC card to a corresponding server via the Internet. The remote controller control CPU 203 that has received information from the set CPU 205 of the television receiver 200 that has received a response from the server has acquired the information obtained by the set CPU 205 from the remote controller 100 through the RF transceiver 202 by the above-described short-range wireless communication. Information is read out, and information is read from and written into the IC card via the CPU 103 of the remote controller 100.

  By repeating such a procedure several times, when the payment process of the price using the IC card is completed and reading and writing to the IC card are no longer necessary, the remote control CPU 203 of the television receiver 200 controls the remote control 100. Information to that effect is transmitted to the CPU 103, and the power of the reader / writer 106 is turned off.

  On the other hand, when the user performs normal operations such as volume adjustment and channel switching on the television receiver 200, the CPU 103 of the remote controller 100 transmits and receives an operation command corresponding to the input operation at the user key operation unit 105 by RF transmission / reception. Only the transmission to the television receiver 200 via the unit 102 and the antenna 101 is performed.

  At this time, the remote control CPU 203 of the television receiver 200 only performs control corresponding to the operation command received from the remote controller 100, and does not necessarily need to transmit a response signal to the remote controller 100.

  Accordingly, the power source of the reader / writer 106 provided in the remote controller 100 remains turned off and does not relate to these operations at all.

  As described above, in the communication system 1, the remote controller 100 includes the reader / writer using the RFID communication method for reading and writing information with respect to the IC card, so that the user can use the IC card for charging or the like performed on the Internet. The operation in the processing using can be performed at a position away from the television receiver 200.

  Further, in the communication system 1, a plurality of communication paths having different communication methods are provided by making the communication method in the normal operation from the remote controller 100 for the television receiver 200 the same as the communication method in the transmission / reception of information to / from the IC card. Therefore, the increase in the number of parts and the associated increase in cost can be prevented, and the device can be downsized.

  Further, in the communication system 1, the power supply of the reader / writer 106 is turned off in a normal key operation such as transmission of an operation command, and is turned on only when the reading and writing of the IC card is necessary. Can reduce consumption.

  In the present embodiment, the case where the communication system 1 includes the television receiver 200 as an electric device has been described. However, any electric device that receives an operation command from a remote controller may be included. .

  Next, the arrangement and the like of each component of the remote controller 100 configured as described above will be described in detail.

  FIG. 4 is an example of a front view of the remote controller 100 according to the present embodiment. FIG. 5 is a diagram schematically showing the inside of the remote controller 100.

  As shown in FIGS. 4 and 5, the remote controller 100 includes a box-shaped housing 10 including a front cover 10 a and a back cover 10 b and a key operation unit 105, and an operation key member formed of a rubber material or the like. 11a to 11c and a substrate 12 which is disposed in the housing 10 and attached to the back cover 10b.

  The housing 10 includes a front cover 10a having a hole through which a convex portion operated by a user is penetrated, and a back cover 10b among the operation key members 11a to 11c. The back cover 10b includes an attachment portion (not shown) inside, and stores the substrate 12 attached to the attachment portion. Further, the back cover 10b is provided with a battery storage portion (not shown) for storing a dry battery for power supply. This battery storage part is covered with a back cover that is a part of the back surface of the housing 10, and when replacing the dry battery, the engagement between the claw portion of the back cover and the back surface of the housing is released, The back cover can be opened.

  As shown in FIG. 4, the operation key members 11 a to 11 c are displayed on the power key 13 for controlling the power on / off of the television receiver 200 and the screen display unit 207 of the television receiver 200. Based on the guidance, a ring-shaped direction key 14a displayed with “←”, “↑”, “→”, “↓” operated to move the cursor displayed on the display screen, and a circle at the center position Selection key 14b, a selection key 14 including various display selection keys 14c for displaying a screen such as a program guide, an up / down tuning key 15 for up / down tuning, and a volume for volume adjustment. An adjustment key 16, various function keys 17, and number keys 18 a to 18 l arranged with numbers from “1” to “12” for channel selection arranged in the approximate center of the remote controller 100 are arranged. There.

  The selection keys 14a to 14c are displayed on the display screen of the television receiver 200 when, for example, the user wishes to distribute contents such as movies, animations, dramas, sports, and games from an Internet server. This is used when content is selected and determined based on the guidance. Specifically, when a content selection screen on which a list of purchaseable content distributed via the Internet is displayed on the display screen of the television receiver 200, the user is displayed at the center of the remote controller 100. By operating the arranged direction key 14a, the cursor is moved to the display position of the desired content displayed on the screen, and distribution is desired by pressing the enter key 14b at the display position of the desired content. Determine the content. Next, when moving to the purchase procedure screen, the procedure proceeds to the purchase procedure for the content online. At that time, if there is a change in the content, it is possible to return to the content selection screen by pressing the selection key 14c on which “return” is displayed. As described above, the selection key 14 shown in FIG. 4 is a key that needs to be operated when selecting a service or purchasing a content via the Internet, for example.

  Needless to say, the selection keys 14a to 14c are not used only when services are provided via the Internet, but may be used as an operation system used in normal television operations in a television receiver.

  The up / down tuning key 15 and the volume adjustment key 16 are operation keys each having a display of “+” and “−”. By pressing the “+” key, the up / down tuning key 15 selects the station number. The channel can be selected in the direction in which the volume increases, and the volume can be increased with the volume adjustment key 16. Also, by depressing the “−” key, the opposite operation can be performed. When the remote controller 100 reads / writes information from / to the IC card, the up / down tuning key 15 and the volume control key 16 can be used as operation keys necessary for information read / write processing. is there. Details will be described later.

  The number keys 18a to 18l are operation keys for direct channel selection, and the numbers described in the number keys 18a to 18l correspond to channel numbers, respectively, and correspond to channel numbers desired by the user. By pressing the numeric keys 18a to 18l, the television broadcast channel received by the television receiver 200 is changed. In the remote controller 100 according to the present embodiment, the part where the numeric keys 18a to 18l are arranged overlaps the card reading unit 20 of the IC card, and the reader / writer 106 is placed on the same substrate surface where the operation keys are arranged. An antenna 107 is provided. Details will be described later.

  Other various function keys 17 include, for example, a screen switching key for switching to a service provider selection screen for receiving a VOD (Video On Demand) service, an input switching key, a broadcast switching key for selecting analog broadcasting or digital broadcasting, Although it consists of a recording key, a recording reservation key, etc., the various function keys 17 are not restricted to these, and are not essential.

  In the remote controller 100 according to the present embodiment, the operation key members 11a to 11c including these various operation keys are formed so as to be able to be pressed by forming a convex portion with resin or the like, and a hole into which each operation key can be fitted is formed. The key operation unit 105 is configured by being attached to the front cover 10a. The functions of these various operation keys are not limited to those described above, and are not essential. Furthermore, it goes without saying that the types of operation keys and the key arrangement on the remote control surface are not limited to the types and arrangements described above, and various operation keys can be arranged.

  In the present embodiment, the state of the remote controller 100 viewed from FIG. 4 showing the front view of the remote controller 100 is referred to as the front direction of the remote controller 100. Note that, when operated by the user, it is not always necessary to operate the front direction toward the television receiver 200. As described above, communication with the television receiver 200 is performed using RF signals. Even if the remote controller 100 is directed in the direction opposite to the front direction, wireless communication with the television receiver 200 is possible.

  The substrate 12 is attached to the back cover 10b constituting the housing 10, and controls the antenna 101 for communicating with the television receiver 200, the RF transceiver 102 for transmitting and receiving RF signals, and the remote controller 100. The CPU 103, the memory 104, the circuit board of the reader / writer 106 that reads and writes information recorded in the IC card, and the voltage for operating the IC chip in the IC card are generated and supplied, and the IC card And an antenna 107 for performing communication.

  FIG. 6 is a diagram schematically showing an arrangement configuration of each constituent member on the substrate 12 of the remote controller 100 according to the present embodiment. As shown in FIG. 6, an RF transmission / reception unit 102 and an antenna 101 for communicating with the television receiver 200 are disposed at the front end portion of the remote controller 100 in the front direction. A circuit board of the reader / writer 106 that controls writing is arranged as a separate board at a substantially central portion of the remote control 100, and a CPU 103 that controls the remote control 100 itself is arranged behind the circuit board. In the remote controller 100, the loop antenna 19 in which lead wires are formed in a loop shape so as to surround the periphery of the substrate portion on which the numeric keys 18a to 18l for direct channel selection are arranged is a reader / writer 106. It is arranged as an antenna 107 for use. Further, in the remote controller 100, a battery serving as a power source is disposed inside the loop antenna 19 corresponding to the antenna 107 of the reader / writer 106 formed in a loop shape, away from the loop antenna 19. The arrangement configuration on the substrate 12 is not limited to this.

  The loop antenna 19 generates an AC magnetic field for feeding and reading / writing to / from an electronic information recording medium such as an IC card, and is connected to a circuit board of a reader / writer 106 formed on the board 12. It functions as the antenna 107 for the reader / writer 106. The signal received by the loop antenna 19 is transmitted to the CPU of the reader / writer 106, and the current signal generated from the control from the CPU of the reader / writer 106 is sent to the loop antenna 19 to cause the IC card. Read / write information from / to.

  Here, as described above, the remote controller 100 arranges the various function keys 17 in addition to the numeric keys 18a to 18l inside the loop antenna 19 provided at the end of the board so as to surround the board 12. (See FIG. 5 or FIG. 6). Therefore, the part where the loop antenna 19 is formed becomes the card read / write unit 20 that reads and writes information from and to the IC card, and the IC card is brought close to the card read / write unit 20 in which a magnetic field is generated by the loop antenna 19. The information is read and written by the reader / writer 106. And the said site | part becomes operation parts, such as number keys 18a-18l.

  As described above, in the remote controller 100, the operation key can be arranged inside the loop antenna 19 by forming the loop antenna 19 so that the lead wire passes through the substrate end of the outer peripheral portion of the substrate 12. Thus, the operation keys can be arranged on the same plane as the card read / write unit 20.

  In the above description, the form in which the loop antenna is formed so as to surround the lead wire on the outer peripheral portion of the substrate 12 has been described. However, in FIG. By forming a pattern with the loop antenna 19a, the same effect as when the loop antenna is formed with the above-described lead wire can be realized. Further, in order not to deteriorate the performance of the antenna, the loop antennas 19 and 19a formed of lead wires and patterns and the other patterns and electronic components should be arranged as far apart as possible. preferable.

  As described above, the remote controller 100 arranges the loop antenna 19 as described above, and arranges the operation keys so as to overlap the card read / write unit 20 when viewed from the top in the front direction of the remote controller 100. The surface of the main body can be used effectively. For example, as shown in FIG. 7, a card read / write unit 30 is provided, and a remote control operation easier for the user is possible compared to a remote control not provided with numeric keys. Become.

  In addition, the remote controller 100 can prevent the remote control body from becoming large as in the case where the card reading unit and the numeric key are provided at different positions, and can realize a user-friendly remote controller. Furthermore, by arranging the loop antenna and the operation key on the same substrate, the size of the substrate can be reduced, and the manufacturing cost of the substrate can be reduced.

  Further, in the remote controller 100, the loop antenna 19 is formed with a lead wire or a pattern on the outer periphery so as to surround the substrate 12 as described above so that information can be read from and written to the IC card. As long as it does not contact the antenna 19, as shown in FIG. 6, the battery constituting the battery / power supply unit 108 can be disposed inside the loop antenna 19 without greatly hindering electromagnetic waves generated from the antenna. it can. Thereby, it is not necessary to provide a space for arranging the battery at another position, and the remote controller can be made smaller. In this case, it is more preferable that the battery disposed inside the antenna 107 surrounding the outer periphery of the substrate 12 is disposed at a position where the absolute distance from the antenna is far, that is, at a central position.

  The battery serving as the battery / power supply unit 108 is not necessarily arranged at the above-described position, that is, the inner side where the loop antenna 19 is formed, but is arranged at a position away from the outer side of the loop antenna 19. Of course it does not matter.

  Furthermore, since the remote control 100 according to the present embodiment is provided at the end of the substrate so as to surround the periphery of the substrate 12, the magnetic field is not inhibited by the metal member arranged on the substrate, The reach of the magnetic field generated from the loop antenna 19 extends to the back side of the remote control 100 (back cover 10b side), and information can be read from and written to the IC card from the front side (operation key arrangement side) of the remote control 100. In addition, the information can be read from and written to the IC card from the back side of the remote controller 100. As a result, for example, charging processing and electronic payment can be performed by holding the card read / write unit 20 of the remote controller 100 from the back side of an IC card placed on a non-metallic table. In this case, an electronic component made of metal or the like that inhibits the magnetic field generated from the antenna is not arranged below the loop antenna 19 (on the back side of the main body).

  As another embodiment, a loop antenna 19b may be formed as shown in FIG. FIG. 8 is a schematic diagram showing an internal configuration of the remote controller 100 according to the other embodiment, and FIG. 8A is a diagram in which the front cover 10a is removed and orthographicly projected from the surface of the remote controller 100. FIG. 8B is a schematic cross-sectional view of the remote controller 100, and FIG. 8C is a diagram in which the rear cover 10b is removed and orthographicly projected from the rear surface of the remote controller 100. FIG. More specifically, the remote controller 100 according to another embodiment has a double-sided board provided with a loop antenna 19b formed in a pattern on the back side of the board on which operation keys are arranged. The card read / write unit 20 is formed by the antenna 19b, and is arranged so that at least one of the plurality of operation keys overlaps with the card read / write unit 20 when viewed from the front in the front direction of the remote controller 100. It is what I did. In this case, the card read / write unit 20 is formed on the back side (the back cover 10b side) of the remote control 100, and the user positions the card read / write unit 20 on the back side of the remote control 100 with respect to the IC card. As a result, reading / writing of information by the reader / writer 106 is performed.

  In addition, by considering the material, arrangement, wiring, and the like of components on the substrate 12, information can be read from and written to the IC card even from the front surface side of the remote controller 100.

  As described above, the double-sided board with the loop antenna 19b formed on the back side of the board 12 on which the operation keys are arranged is arranged in the casing 10 of the remote controller 100, and at least one operation key and the card read / write unit 20 are provided. By arranging them to overlap, the surface of the remote controller 100 can be used effectively, and it is possible to provide sufficient operation keys and the card read / write unit 20 without reducing the number of operation keys. Is operated by positioning the card read / write unit 20 on the back side of the remote control 100 with respect to the IC card, so that all the operation keys provided on the surface of the remote control 100 are not hidden by the IC card, Operations required for reading and writing cards can also be performed easily. Note that the loop antenna may be formed on a separate substrate and may be formed in multiple layers with the substrate on which the operation keys are arranged. In addition to forming a loop antenna by forming a pattern, a loop antenna may be formed by a lead wire, and the lead wire may be provided on the back surface of the operation key substrate.

  In this case, the battery constituting the battery / power supply unit 108 is arranged away from the loop antenna at a position different from the board that does not overlap the board when viewed from the top in the front direction of the remote control 100. By doing so, the influence which the metal part of the battery has on the loop antenna can be further reduced.

  Next, in the case of purchasing information such as movies, animations, dramas, sports, games, etc. from an Internet service provider regarding the read / write operation of information with respect to the IC card by the user using the remote controller 100 having the reader / writer 106. A specific example will be described.

  When a user purchases content such as a movie or animation from an Internet service provider, the user performs necessary operations, specifically, selections with the remote controller 100 while viewing a list of contents and an operation screen displayed on the television receiver 200. The content to be purchased is selected by operating the key 14 (for example, the direction key 14a including “←”, “↑”, “→”, and “↓”), and the purchase is determined by pressing the enter key 14b. Then, when the user decides the payment method of the content using the IC card and pays the purchase price, the reader / writer 106 of the remote controller 100 reads the information recorded in the IC card and information on the IC card. Write process. At that time, the user operates while holding the IC card over the card read / write unit 20 provided in the remote controller 100.

  In this way, the user performs a content purchase operation by operating the selection key 14 while holding the IC card over the card read / write unit 20 of the remote controller 100.

  Information read from the IC card is transmitted to the television receiver 200 via the RF transmission / reception unit 102 and the antenna 101, and this information is sent to the server via the Internet by the television receiver 200. Upon receiving the response from the server, the CPU 203 of the television receiver 200 transmits information from the server to the remote controller 100 through the above-described short-range wireless communication, and reads information from the IC card via the CPU 103 of the remote controller 100. Write. The content purchase procedure is completed by repeating this process several times.

  Conventionally, in the procedure for purchasing content such as a movie distributed via the Internet as described above, a user can connect a USB (read / write unit of a reader / writer provided in the television receiver or a USB ( Since the information stored in the IC card is read by bringing the IC card close to the reader / writer connected by Universal Serial Bus), etc., the channel control of the television receiver is performed using a remote control. In spite of being able to be operated remotely, when reading and writing of an IC card is required in the content purchase procedure, etc., it has been necessary to move to the place where the television receiver is installed and operate it.

  The remote controller 100 in this embodiment includes a reader / writer 106 that reads and writes information on an IC card, so that the user can turn on / off the television receiver 200, select a channel, and the like. Similar to the operation in, operations for reading and writing information to and from the IC card by the reader / writer 106 can be performed by holding the IC card over the card read / write unit 20 of the remote controller 100 at hand. Comfortable user operation can be realized.

  In addition, the remote controller 100 has “1” to “12” in the same part as the card read / write unit 20 for executing reading and writing of information with respect to the substrate inside the part where the loop antenna 19 is formed, that is, the IC card. Since the number keys 18a to 18l displaying the numbers are arranged, the number keys 18a to 18l are hidden by holding the IC card over the card read / write unit 20 at the time of card reading / writing such as electronic payment. Become. As described above, at the time of reading and writing information to the IC card, the user mainly uses the direction key 14a for selecting content or the like among the operation keys of the remote controller 100, the decision key 14b for determining the purchase, and the like. Use it for billing. Therefore, at the time of reading and writing information on the IC card, the frequency of using the numeric keys 18a to 18l that are hidden by holding the IC card over the card read / write unit 20 is low, and the operation of the remote controller 100 is inconvenient. There is no.

  As described above, in the remote controller 100 according to the present embodiment, even when the numeric keys 18a to 18l are arranged inside the portion of the reader / writer 106 where the loop antenna 19 is formed, information reading from the IC card and The operation keys necessary for writing can be operated without inconvenience. That is, operation keys (such as the direction key 14a in this embodiment) required when reading / writing information to / from the IC card by the reader / writer 106 are not hidden by the IC card even when the IC card is held over the card read / write unit 20. Since it is arranged at the position, the user does not deteriorate the usability of the remote controller 100.

  On the other hand, at the time of reading and writing information with respect to the IC card, for example, when performing content purchase price setting or purchase quantity setting, the numeric key 18a to be hidden by the IC card by holding the IC card over the card read / write unit 20 It may be necessary to operate 18l. In such a case, when the user stops releasing the IC card from the card read / write unit 20 and approaches the part, and presses the numeric keys 18a to 18l, the magnetic field generated from the loop antenna 19 reaches the IC card. As a result, the reading / writing processing of information with respect to the IC card by the reader / writer 106 is not performed normally. Then, there is a possibility that unexpected trouble may be caused in reading and writing processing of information with respect to an IC card in which electronic money information or the like is recorded.

  Therefore, the remote controller 100 controls the CPU 103 of the remote controller 100 to change the function of the arranged operation key when the reader / writer 106 reads and writes information on the IC card, so that the user can read and write the IC card. All necessary operations can be performed by using an alternative key whose function is changed.

  Specifically, when the CPU 103 of the remote controller 100 recognizes that the reader / writer 106 is turned on at the time of reading and writing information with respect to the IC card, for example, “up / down tuning key 15“ The “+” / “−” key is assigned to the function to increase / decrease the amount of money, and the “+” / “−” key of the volume control key 16 is assigned to the function to operate the increase / decrease of the purchased quantity, respectively, and automatically changed. When it is recognized that the reader / writer 106 is turned off, the function change of the operation key is canceled and the operation key is controlled to return to the meaning of the normal function. Yes. Accordingly, even if the numeric keys 18a to 18l that are hidden by holding the IC card over the card read / write unit 20 are not operated, the operation keys that are not hidden by the IC card and operated by the function are replaced. It is possible to set the purchase price and set the purchase quantity.

  Thus, since the remote controller 100 is controlled to change the function of the operation key when reading / writing information by the reader / writer 106, it is impossible to operate by holding the IC card over the card read / write unit 20. It becomes possible to substitute the function of the changed operation key with another key. In addition, since the CPU 103 of the remote controller 100 automatically determines and controls the operation key function changing process, the function switching process is performed using the mode key, or simultaneous pressing while pressing the shift key. Thus, it is possible to easily perform operations without forcing the user to perform troublesome operations such as changing the function of the operation keys.

  Note that the remote controller 100 can perform two-way wireless communication with the television receiver 200. Therefore, when the function of the operation key is changed as described above, the reader / writer 106 is used. For example, the CPU 103 of the remote controller 100 may control the television receiver 200 to transmit a command for displaying on the screen a guidance display that guides the operation method of the remote controller 100 when the IC card is read or written by. Thereby, the user can operate according to the guidance with a simple operation, and can save the trouble of confirming the operation key whose function is changed while referring to the instruction manual or the like.

  Further, the remote controller 100 may turn on an LED indicating that the function of the operation key is switched when reading / writing information from / to the IC card. In this case, since the operation key can be switched at the same time as the on / off of the reader / writer 106, the CPU 103 of the remote controller 100 detects the on / off of the reader / writer 106 by detecting the on / off of the LED. The turning-off can be controlled, and the lighting display of this LED can also serve as a display indicating that the reader / writer 106 is operating.

  Furthermore, since the remote controller 100 can perform two-way wireless communication with the television receiver 200 and can grasp the on / off state of the reader / writer 106, the remote controller 100 can be operated on the television screen. You may make it display that the key has switched.

  It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.

  For example, in the above-described embodiment, the remote controller 100 reads and writes information from and to a non-contact type IC card using RFID. However, the remote controller reads or writes information from or to a contact type magnetic card. A configuration may be employed in which writing is performed. Further, the non-contact type information recording medium is not limited to the IC card, and for example, an electronic device such as a mobile phone having the function of the non-contact IC card may be used as described above. .

  Moreover, although the arrangement configuration of each member on the board | substrate of this remote control 100 was shown in FIG. 6, the arrangement | positioning of each said member is not restricted to this.
