Description

  The present invention inserts a wireless communication medium into an electronic device when communicating with a wireless communication medium such as an IC tag to be inserted into an electronic device such as a mobile phone or a portable terminal, and a read / write unit such as an external card reader. Even in such a case, the insertion type wireless communication medium device and the electronic device that reduce the influence of the metal surface in the electronic device, enable communication between the external read / write unit and the wireless communication medium, and expand the communication distance. The purpose is to provide equipment.

  A wireless communication medium having an ID code, such as an IC card or an IC tag, and a wireless communication medium processing apparatus for performing ID code authentication of the wireless communication medium are used for authentication, baggage destination distribution, and the like. It is increasing. When the communication mounted medium exists in the communication range of the communication mounted medium processing apparatus, an induced voltage is generated in the antenna of the wireless communication medium by the magnetic field from the antenna, and this voltage is rectified to supply power and transmission data. In a wireless communication medium to which power is supplied, according to data read from the mounted memory, for example, in a modulation circuit composed of a load resistor and a switch connected to an antenna, according to data 1 and 0 The switch is turned on and off. With this on / off, a load variation occurs on the antenna of the wireless communication medium, and this load variation is transmitted as a signal to the antenna on the communication medium processing apparatus side. The transmitted signal is demodulated and its ID code authentication is performed (see, for example, Patent Document 1).

  Here, for example, in a portable terminal such as a cellular phone or other electronic device, an IC tag or an IC card is inserted, and for example, communication between the portable terminal and an external read / write unit such as a non-contact reader is performed. For example, it has been proposed that the terminal itself perform ID authentication. For example, a wireless communication medium is inserted into a mobile phone in advance, and entrance / exit management is performed, or processing such as a ticket gate at a station is performed.

Alternatively, it has been proposed to insert a dedicated electronic authentication card or the like other than the wireless communication medium into the electronic device and read out the electronic authentication card inserted into the electronic device (for example, see Patent Document 2).

  However, when a general-purpose wireless communication medium such as an IC tag or an IC card is inserted into an electronic device such as a portable terminal instead of a dedicated electronic authentication card, the metal surface of the portable terminal, the metal component, and the antenna included in the wireless communication medium There is a problem that communication with an external communication-mounted medium processing apparatus becomes almost impossible due to the influence of the resonance frequency deviation of the antenna, impedance fluctuation, and the like due to interference with the antenna.

  From the above, there is a problem that it is difficult to realize various applications and processing systems that store a wireless communication medium in an electronic device such as a portable terminal and communicate with an external read / write unit.

In view of the above-described problems, the present invention has a wireless communication medium that can be inserted into an electronic device even when the wireless communication medium is inserted into an electronic device such as a portable terminal, and the metal surface or metal component in the electronic device. It is an object of the present invention to realize an insertion type wireless communication medium device and an electronic apparatus that can reduce interference with an antenna, eliminate the influence of a resonance frequency shift of the antenna, an impedance variation, and the like, and can communicate with ensuring a sufficient communication distance.

  The present invention includes a wireless communication medium and a magnetic member provided on at least one of a bottom surface of the wireless communication medium or a surface facing the wireless communication medium.

  According to the configuration of the present invention, when a wireless communication medium having an ID code or the like is inserted into an electronic device such as a portable terminal, the magnetic field is bypassed by a magnetic plate formed on any surface such as the bottom surface of the wireless communication medium. Since the path can be formed, the influence of the metal surfaces and metal parts inside and outside the electronic device on the antenna of the wireless communication medium is reduced, and communication is performed between the external read / write unit such as a non-contact reader and the wireless communication medium. Can be done.

  Here, in particular, by forming a magnetic member on the surface facing the wireless communication medium, the magnetic member ensures the passage of magnetic flux, and the metal surface or metal part of the electronic device is applied to the antenna of the wireless communication medium. The influence is reduced, and the exchange of the magnetic field between the wireless communication medium and the outside becomes possible. That is, it is ensured that communication between a wireless communication medium inserted in an electronic device and an external read / write unit can be performed.

  Further, by disposing a metal member outside the magnetic member, impedance changes to the antenna of the wireless communication medium both when the wireless communication medium is outside the electronic device and when it is inserted inside the electronic device In addition, the communication distance between the inserted wireless communication medium and the external read / write unit can be further increased by greatly reducing the influence of frequency deviation.

  In addition, by storing the wireless communication medium in the case, it is easy to carry the wireless communication medium, further improve durability and weather resistance, and it is possible to easily insert the desired wireless communication medium into the electronic device. Become. This is particularly effective when it is desired to change the wireless communication medium desired to be used.

  Furthermore, by making the wireless communication medium or the case for storing it thin, electronic devices such as mobile terminals can be inserted from the side, etc., and do not hinder downsizing of electronic devices, It becomes easy to insert.

  In addition, since the case where the wireless communication medium is stored is a thin case, it can be easily inserted into an electronic device such as a cellular phone or a thin notebook personal computer. Communication between a wireless communication medium incorporated in the medium device and an external read / write unit can be performed.

  In addition, by forming a metal plate on the outside of the magnetic plate, the impedance to the antenna of the wireless communication medium both when the wireless communication medium is outside the electronic device and when it is inserted inside the electronic device The communication distance between the inserted wireless communication medium and the external read / write unit can be further increased by greatly reducing the influence of changes and frequency deviations.

  Furthermore, by providing a loop antenna around, the loop antenna provided in the read / write unit such as an external non-contact reader and this loop antenna are coupled by mutual induction. A strong magnetic field is generated around the antenna, and a strong magnetic field can be applied to the antenna of the wireless communication medium. Similarly, it is possible to further increase the communication distance with the external non-contact reader by increasing the fluctuation of the load of the antenna of the internal wireless communication medium in the reverse direction.

  In particular, at this time, since the loop antenna may be parasitic, it does not cause excessive power consumption and does not affect the electronic device. In addition, since the loop antenna can be formed with a printed pattern or the like, the electronic device is hardly increased in size.

  In addition, by forming the loop antenna together with the insertion type wireless medium device in advance, it can be inserted into an electronic device including the loop antenna, and is adapted to the shape, size, orientation, etc. of the wireless communication medium. It can be a loop antenna.

  In addition, the loop antenna is formed in advance around the insertion portion into which the insertion type wireless communication medium is inserted, such as an electronic device, so that the insertion type wireless communication medium device can be inserted without separately preparing the loop antenna. The communication distance can be increased using the effect of the loop antenna. Further, there is an effect that the insertion type wireless communication medium device can be used without changing the size or shape of, for example, a standardized IC card or IC tag.

  Due to the above effects, even if a wireless communication medium is inserted into the electronic device without causing a problem such as an increase in the size of the electronic device such as a portable terminal, Reduces interference between metal parts and antennas of wireless communication media, eliminates the effects of antenna resonance frequency shifts and impedance fluctuations, enables communication with external read / write units, and ensures an expanded communication distance be able to.

  There are various electronic devices such as mobile phones, mobile terminals, notebook computers, faxes, telephones, PDAs, portable TVs, car navigation systems, etc., and they are thin and small for easy insertion. There are many things to do. Moreover, although the term “insertion” is used, it may be inserted not only from an insertion part such as a slit but also to be able to be taken in and out from a normal takeout port. In a broad sense, it means being stored and taken out from the outside in the internal space.

  In addition, the wireless communication medium 3 is preferably a thin shape that can be easily inserted into an electronic device, but may have other shapes as necessary. is there.

  Next, Case 4 will be described.

  The case 4 is a case for storing the wireless communication medium 3 and is formed of resin or ceramic. In addition, the shape may be determined according to the application, and it may be a plate-like object such as a rectangle, a rectangle, a square, an ellipse, a circle, a triangle, a polygon, or a columnar person such as a prism or a cylinder. good. In addition, the chamfering of the corners has the advantage of improving durability and improving user friendliness.

  In addition, the shape, area, thickness, etc. of the case 4 are often determined by the standard of the electronic equipment that is inserted and used. It is preferable to have. For this reason, when there are a large number of various standards, it is also preferable to prepare a case 4 having a shape and an area suitable for each of the standards in advance to cope with various variations.

It is also preferable to store an internal data rewrite control circuit, a fault detector, an LED issuing element, or the like.

  Although not shown in FIGS. 1 and 2, the insertion-type wireless communication medium device 1 is inserted into an electronic device or the like, so that electrical communication between the internal space 2 and the inside of the electronic device is possible. As described above, the case 4 is formed with electrodes and electrical terminals, and the case 4 is preferably connected to the electrical terminals (not shown) of the internal space 2 and the like.

  Next, the magnetic member 5 will be described.

  The magnetic member 5 is provided on the bottom surface of the wireless communication medium 3, the bottom surface of the case 4, or the surface facing these. That is, as a result, it is formed on the surface facing the main surface of the wireless communication medium 3.

Since the magnetic flux passes through the metal plate where the magnetic flux density is concentrated without touching the metal plate and the magnetic flux density is sparse, the generation of eddy current is reduced and the loss caused thereby can be reduced. As a result, communication with the wireless communication medium 3 becomes possible.

  At this time, in order to ensure strength and durability, the magnetic member 5 is also preferably chamfered at a corner or round or oval. In addition, since the magnetic flux can pass through more because the thickness is thicker, and as a result, the radiation of the magnetic field to the outside can be made stronger. In addition, it is also preferable to keep it thick.

The communication distance between the inserted wireless communication medium 3 and the external read / write unit is further expanded by greatly reducing the influence of impedance change and frequency shift on the wireless communication medium antenna 7 of the wireless communication medium 3. It becomes possible.

  Further, by providing the metal member 10 on the outside of the magnetic member 5 in this manner, the wireless communication medium antenna 7 included in the wireless communication medium 3 has a metal surface in the vicinity of the magnetic member 5 or more than the magnetic member 5 alone. It is possible to further reduce the influence of metallic parts and the like, and the communication distance is further increased.

  That is, the magnetic member 5 and the metal member 10 are formed in this order on the bottom surface of the wireless communication medium 3 or the case 4 (or the opposing surface that faces the main surface formed by the wireless communication medium 3). This makes it possible to insert the wireless communication medium 3 such as an IC card or an IC tag into an electronic device, which has been difficult with the conventional technology, and perform authentication of the ID code or the like from an external read / write unit. Is.

  Next, the control circuit 11 will be described.

  For example, the ID code stored in the IC or memory of the wireless communication medium 3 can be changed by data access processing when it is desired to change the ID code afterwards. When inserted in an electronic device or a dedicated device, the data stored in the internal space 2 is written into the wireless communication medium 3 and executed to change the ID code of the wireless communication medium 3 or By storing various data, an insertion type wireless communication medium device with high flexibility can be obtained.

  Alternatively, it is not an inactive wireless communication medium 3 that operates by an induced electromotive force by applying electric power to an ordinary wireless communication medium 3 inside an electronic device and receiving a magnetic field from a read / write unit. It is also preferable that the active wireless communication medium 3 that emits radiates and enables communication even in an extremely severe communication environment.

  In such a case, since a highly user-friendly device is realized, it can be easily applied to various applications.

  For example, when using a mobile phone or the like with the insertion type wireless communication medium device 1 inserted as an admission ticket for a concert or a public institution, the stored contents of the wireless communication medium 3 can be rewritten so that it can be used in a very wide range. An aspect is realized.

  Further, a circuit or software for rewriting processing may be provided on the electronic device side.

  Next, the loop antenna 12 will be described with reference to FIGS.

  8 and 9 show a state in which the loop antenna 12 is formed around the wireless communication medium 3, and FIG. 10 shows a loop antenna around the case 4 in which the wireless communication medium 3 is stored. 12 shows a state in which 12 is formed, and FIG. 11 shows a state in which the loop antenna 12 and the storage case 16 are stored.

  The loop antenna 12 is an antenna formed of a conductor and having an opening, and is formed so as to surround the wireless communication medium 3 or the case 4. The conductor forming the loop antenna 12 may be any conductor such as various metals, and is formed of a material such as gold, silver, copper, aluminum, brass, or an alloy thereof.

  The loop antenna 12 is non-powered with no signal current.

Here, even if no power is supplied, the loop antenna 12 works as if it is supplied with power because an induced current is generated with respect to the magnetic field from the external read / write unit, and generates a magnetic field.

  Further, the loop antenna 12 serves as a relay between the external read / write unit and the antenna included in the internal wireless communication medium 3 to generate a large induced electromotive force and extend the range of the magnetic field. As a result, the communication distance between the wireless communication medium 3 and the external read / write unit is increased by the loop antenna 12.

  The loop antenna 12 may be formed so as to surround the periphery of the case, but the surface of the case 4 and the surface of the opening made by the loop antenna 12 do not have to be substantially on the same plane, and are sufficient if they are in the vicinity. Yes, and some of them may overlap.

  Further, the opening preferably has a larger area than the case 4, and further preferably has a larger area than the wireless communication medium 3 stored inside the case 4. As a result, a strong magnetic field is generated around the loop antenna 12, and a strong magnetic field can be applied to the antenna of the wireless communication medium 3 inside the insertion-type storage medium device, thereby further extending the communication distance with the read / write unit. It is.

  Moreover, it is preferable that the opening surface of the opening of the loop antenna 12 and the wireless communication medium 3, particularly the antenna included in the wireless communication medium 3, are substantially parallel. This is because the magnetic field strength is further increased and the communication distance with the wireless communication medium 3 is increased.

  Note that the loop antenna 12 may be formed separately from the wireless communication medium 3 as shown in FIG. 8, and in this case, it may be entirely separate or may be connected by a connecting part such as a screw.

  Alternatively, as shown in FIG. 11, the entire storage case 16 may be integrated and stored together in a storage case 16 that stores the whole. In this case, the entire storage case 16 is inserted into an insertion portion of an electronic device. The insertion type wireless communication medium device. In this case, although the size is somewhat large, there is an advantage that the insertion type wireless communication medium device 1 in which the loop antenna 12 that expands the communication distance is stored in advance can be obtained.

  Next, the resonance circuit 13, the matching circuit 14, and the termination resistor 15 will be described.

  These are all connected to the loop antenna 12 and are for improving the performance at the time of communication with the loop antenna 12.

  The resonance circuit 13 is a circuit for resonating at an arbitrary frequency used in communication and determined to perform communication operation at a frequency determined by a standard or the like. It is determined by appropriately connecting the capacity components and inductor components. It is also preferable to be able to respond to changes in the operating frequency with a volume or the like.

  The matching circuit 14 is a circuit for impedance matching. Since impedance matching is achieved, extra reflected waves are eliminated, VSWR is improved, and communication performance can be improved. Matching can be achieved by appropriately using a resistance component, a capacitance component, an inductor component, and the like. At this time, it is also preferable that the matching can be adjusted later using a volume circuit or the like. It is also preferable to share components that can be shared with the resonance circuit 13 and to perform as necessary.

The termination resistor 15 is a resistor that terminates for matching in the loop antenna 12, and a necessary resistance component is appropriately connected thereto. In particular, these are more effective constituent elements because the extra reflected wave is eliminated and the parasitic loop antenna 12 is provided.

  With the above configuration, communication between the wireless communication medium 3 stored in the insertion-type wireless communication medium device 1 inserted into an electronic device covered with a metal surface and an external read / write unit is possible. The communication distance can be made sufficient.

  Next, the operation of the insertion type wireless communication medium device 1 will be described.

  First, the magnetic member 5 is disposed at a position facing the main surface of the wireless communication medium 3, such as the bottom surface of the wireless communication medium 3 or the case 4, so that a magnetic field is generated between the wireless communication medium 3 and the magnetic member 5. Thus, a portion having a high magnetic flux density is concentrated on the magnetic member 5 under the wireless communication medium antenna 7, and a magnetic flux loop (closed circuit) can be efficiently formed. Since the magnetic flux passes through the metal plate where the magnetic flux density is concentrated without touching the metal plate and the magnetic flux density is sparse, the generation of eddy current is reduced and the loss caused thereby can be reduced. As a result, communication between the external read / write unit and the wireless communication medium 3 becomes more reliable.

  In particular, at this time, the metal member 10 is further formed under the magnetic member 5, so that the case where the wireless communication medium is stored is outside the electronic device and the case where the case is inserted into the electronic device. In any case, the communication distance between the inserted wireless communication medium 3 and an external read / write unit is further expanded by greatly reducing the influence of impedance change and frequency shift of the wireless communication medium antenna 7 of the wireless communication medium 3. It becomes possible.

  Furthermore, by forming the loop antenna 12, the antenna provided in the read / write unit such as an external non-contact reader and the loop antenna 12 are coupled by mutual induction, and the loop antenna 12 serves as an intermediary. A strong magnetic field is generated around the loop antenna 12, and a strong magnetic field can be applied to the wireless communication medium antenna 7 of the wireless communication medium 3 inside the insertion-type storage medium device. The fluctuation of the load of the wireless communication medium antenna 7 of the wireless communication medium 3 can be further increased to easily extend the communication distance with the external non-contact reader, and the practical merit is very high.

  As described above, even when the wireless communication medium 3 is stored in advance in the insertion-type wireless communication medium device 1 such as a memory card and inserted into various electronic devices, communication with an external read / write unit is enabled. ID code authentication can be performed. For example, ID authentication with a non-contact reader or the like can be performed with a mobile phone itself.

  The insertion-type wireless communication medium device 1 is inserted into and removed from various electronic devices such as a portable terminal, a digital camera, a digital video, a television, a video, a DVD, and a personal computer. Furthermore, it is easy to move, carry and handle because of its simple handling and ease of loading and unloading, light weight and portability.

  Next, applied aspects resulting from such operations will be described.

  Since it has the above operation | movement, it will become possible to make various electronic devices into the electronic device which has ID code as needed by inserting in each electronic device. In addition, communication between the wireless communication medium 3 inserted inside and an external read / write unit is possible, and an electronic device capable of authenticating an ID code can be easily realized.

For this reason, it is possible to use electronic devices in a very wide range of ways, and it can be used as an electronic device that can be used effectively in various systems and business scenes. It can be easily extended to admission management, security system construction, network and file system access restrictions, document and media management, and automatic inventory systems. In addition, since existing electronic devices can be used without any particular improvement, the cost for diffusion is very low.

  Note that the loop antenna 12 may be provided as necessary, and the provision of the loop antenna 12 has an advantage of extending the communication distance, but it goes without saying that communication is possible even when the loop antenna 12 is not formed.
