Below, the whole structure of a communication terminal device, the electrical structure of a communication terminal device, and the structure of the antenna with which a communication terminal device is provided are demonstrated in order.

[Overall configuration of communication terminal device]
The overall configuration of the communication terminal apparatus will be described with reference to FIG. 1 and FIG.
As illustrated in FIG. 1, the communication terminal apparatus 10 includes a mounted portion 11 that is mounted on a user H. When the mounted portion 11 is in the state shown in FIG. 1 and is mounted on the user H, it is most important that the mounted portion 11 has an annular shape. It may have an endless ring shape. When the mounted part 11 has an endless ring shape in the mounted state, the mounted part 11 forms an endless ring shape by, for example, the first mounting end part 11a and the second mounting end part 11b being in contact with each other. To do.

  The attached part 11 only needs to be attached to a part of the body of the user H, and the part to which the attached part 11 is attached is the wrist, finger, neck, arm, and ankle of the body of the user H. Any of these may be used. Even if it is a case where it is a case where it is a case where it is a case where it mounts | wears with any part in the user's H body, the to-be-attached part 11 has the ring shape surrounding the whole in the circumferential direction of each site | part, or a part in the circumferential direction of each site | part. Just do it. FIG. 1 shows a wristwatch-type communication terminal device 10 worn on the wrist of the user H as an example of the communication terminal device 10.

  The communication terminal device 10 preferably includes a display unit 12, and the display unit 12 is positioned on the outer surface of the mounted unit 11, and preferably is positioned on a surface that does not contact the user H in the mounted unit 11. . For example, the display unit 12 displays various character information and graphic information according to the operation of the communication terminal device 10 by the user H.

  An antenna 21 that communicates with the outside is located inside the mounted portion 11. The mounted portion 11 includes, for example, an antenna 21 located on the outer surface of a flexible resin film, and a cover that covers the entire resin film including the antenna or a part of the resin film. The cover forming material is, for example, synthetic resin or metal. When the cover forming material is a metal, the mounted portion 11 has an insulating member that insulates the cover and the antenna 21, and the cover made of metal does not suppress the communication characteristics of the antenna 21. Is preferred.

  The antenna 21 has a ring shape and can communicate with the outside when the communication terminal device 10 is in the mounted state. When the antenna 21 has a ring shape, the antenna 21 communicates with the outside by being coupled to the external antenna by a magnetic field. That is, when the communication terminal device 10 is attached, the antenna 21 is in a communicable state.

  An RF chip 22 connected to the antenna 21 is located inside the mounted portion 11. The RF chip 22 transmits data stored in the RF chip 22 to the outside or receives an information signal from the outside by communication of the antenna 21.

  As shown in FIG. 2, the mounted portion 11 has a non-mounted state that is not mounted on the user H, and the mounted portion 11 has a shape between the above-described mounted state and the non-mounted state. change. When the mounted portion 11 is in a non-mounted state, the mounted portion 11 has a distance between the first mounted end portion 11a and the second mounted end portion 11b in the mounted state. It is larger than the distance from the second mounting end 11b.

  When the mounted portion 11 is in a non-mounted state, the first mounting end portion 11a and the second mounting end portion 11b of the mounted portion 11 connect the first mounting end portion 11a and the second mounting end portion 11b. You may connect by connection members, such as a belt. At this time, the mounted portion 11 has an endless ring shape. Or the 1st mounting end part 11a and the 2nd mounting end part 11b of the to-be-mounted part 11 may mutually separate like the example of the communication terminal device 10 which FIG. 2 shows. When the first mounting end portion 11a and the second mounting end portion 11b are separated in the non-mounted state, the mounted portion 11 may have a linear shape extending in one direction, extending in one direction, and It may have a band shape having a two-dimensional expansion. When the mounted part 11 has a band shape, the width along the direction orthogonal to the direction in which the mounted part 11 extends may be constant in the extending direction of the mounted part 11 or may vary.

  In the example shown in FIG. 2, the mounted portion 11 has a band shape having a first mounting end portion 11 a and a second mounting end portion 11 b which are two end portions. When the communication terminal device 10 includes the display unit 12 and the mounted unit 11 has a band shape in a non-mounted state, the display unit 12 is the center of the mounted unit 11 in the direction in which the mounted unit 11 extends. It may be located in other places.

  When the mounted portion 11 is in a non-mounted state, the antenna 21 includes a first antenna end portion 21a positioned at the first mounting end portion 11a and a second antenna end portion 21b positioned at the second mounting end portion 11b. Are separated from each other. When the mounted part 11 has a linear shape or a band shape in a non-mounted state, the antenna 21 is composed of a line member extending along the direction in which the mounted part 11 extends. When the mounted portion 11 is not mounted, the antenna 21 is composed of a wire member and cannot be coupled to the outside by a magnetic field. That is, when the mounted portion 11 is in a non-mounted state, the antenna 21 is in a communication disabled state where it cannot communicate with the outside.

  As described above, the antenna 21 changes the conduction state between the communicable state and the incommunicable state as the shape of the mounted portion 11 changes between the mounted state and the non-mounted state, and When the mounting unit 11 is in the mounted state, the communication is possible, and when the mounted unit 11 is not in the mounted state, the communication is not possible. For this reason, communication with the outside is possible only when the mounted portion 11 is mounted on the user H. Therefore, in a situation where the user H is not using the communication terminal device 10, the communication terminal device 10 can be prevented from communicating with the outside.

[Electrical configuration of communication terminal device]
The electrical configuration of the communication terminal device 10 will be described with reference to FIG. In the following, an example in which the communication terminal apparatus 10 is a passive NFC tag in NFC (Near Field Communication), which is one of short-range wireless communications, will be described in detail.

  As shown in FIG. 3, the communication terminal device 10 that is an NFC tag includes an antenna 21 and an RF chip 22 connected to the antenna 21. The antenna 21 is a coil having a spiral shape that rotates along the circumferential direction of the mounted portion 11, and the shape of the antenna 21 depends on the area that the antenna 21 can occupy in the communication terminal device 10 and the driving of the RF chip 22. It depends on the power required for the. The antenna 21 having such a shape is easy to form the antenna 21 with respect to the mounted portion 11 as compared with the configuration of a coil having a spiral shape that rotates along the radial direction of the mounted portion 11.

  The RF chip 22 includes an RF unit 31, a logic unit 32, and a storage unit 33. The RF unit 31 is connected to the proximal end and the distal end of the antenna 21, and includes a power supply circuit that extracts power from a magnetic field supplied from the outside, and a data transmission circuit that performs demodulation and modulation of an information signal exchanged with the outside. Including.

  The storage unit 33 can store an identifier unique to the communication terminal device 10 and other information. The storage unit 33 may store an identifier or the like in advance, or may store an identifier received through communication with the outside.

Based on the received information signal, the logic unit 32 reads predetermined information from the storage unit 33 or writes predetermined information to the storage unit 33.
The communication terminal device 10 may be the above-described passive NFC tag, an active NFC tag having a power supply, or a semi-active NFC tag having the same power supply. The communication terminal device 10 may be a reader / writer that reads other NFC tags or writes to other NFC tags, or may be a terminal device that exchanges information signals on a peer-to-peer basis. When the communication terminal device 10 has a reader / writer function and a peer-to-peer function, the communication terminal device 10 has a power supply for causing the communication terminal device 10 to express these functions in addition to the electrical configuration described above. And a control unit. The communication terminal device 10 may have two or more functions among these NFC tag, reader / writer, and peer-to-peer.

[Configuration of antenna]
A more detailed configuration of an example of the antenna 21 will be described with reference to FIG. In FIG. 4, for convenience of illustration, illustration of a cover that covers one side surface of the resin film of the mounted portion and on which the antenna is located is omitted.

  As shown in FIG. 4, when the mounted portion 11 is in a non-mounted state, the mounted portion 11 has a band shape extending along the extending direction that is one direction. The mounted portion 11 includes a resin film 11c having a band shape extending along the extending direction, and a cover 11d that covers two side surfaces of the resin film 11c.

  An antenna 21 and an RF chip 22 connected to the antenna 21 are located on one side surface of the resin film 11c. The antenna 21 includes a first line member 41, a second line member 42, a third line member 43, and a fourth line member 44, and each line member extends along the extending direction. Of the two end portions of each line member, the end portion close to the first mounting end portion 11a of the mounted portion 11 is the base end, and the end portion close to the second mounting end portion 11b is the tip end.

  The first line member 41 extends from the first mounting end portion 11a of the mounted portion 11 to the middle in the extending direction, and is connected to the RF chip 22 at the tip. The proximal end of the first wire member 41 is the first proximal end 21a1.

  The second line member 42 extends from the first mounting end portion 11a toward the second mounting end portion 11b in the mounted portion 11 and on the way from the first mounting end portion 11a toward the second mounting end portion 11b. It has a step which bends along the width direction which is a direction orthogonal to the extending direction. The proximal end of the second wire member 42 is the second proximal end 21a2, the distal end of the second wire member 42 is the first distal end 21b1, and the position of the first distal end 21b1 in the width direction is the first linear member 41. It overlaps with the position of the first base end 21a1.

  The third line member 43 extends from the first mounting end portion 11a toward the second mounting end portion 11b in the mounted portion 11 and is in the middle of extending from the first mounting end portion 11a toward the second mounting end portion 11b. It has a step that bends along the direction. The proximal end of the third wire member 43 is the third proximal end 21a3, the distal end of the third wire member 43 is the second distal end 21b2, and the position of the second distal end 21b2 in the width direction is the second linear member 42. It overlaps with the position of the second base end 21a2.

  The fourth line member 44 extends from the middle of the extending direction of the mounted part 11 toward the second mounting end part 11 b, and the base end of the fourth line member 44 is connected to the RF chip 22. The tip of the fourth wire member 44 is a third tip 21b3, and the position in the width direction of the third tip 21b3 overlaps with the position of the third base end 21a3 in the third wire member 43.

  The cover 11d has a plurality of exposure holes 11e that expose the first base end 21a1 to the third base end 21a3 and the first tip 21b1 to the third tip 21b3, respectively. Therefore, when the mounted portion 11 is in the mounted state, the first mounting end portion 11a and the second mounting end portion 11b of the mounted portion 11 are in contact with each other, whereby the first base end 21a1 and the first tip end 21b1 of the antenna 21 are contacted. The second proximal end 21a2 and the second distal end 21b2, and the third proximal end 21a3 and the third distal end 21b3 are in contact with each other. As a result, the antenna 21 forms a coil antenna having three turns, and the conduction state of the antenna 21 changes from the communication disabled state to the communication enabled state.

  Note that the cover 11d may not have the plurality of exposure holes 11e. In this case, each of the first base end 21a1 to the third base end 21a3 only needs to be exposed on the end surface of the first mounting end 11a that is in contact with the second mounting end 11b. Each of the tips 21b3 only needs to be exposed at the end surface of the second mounting end 11b that is in contact with the first mounting end 11a.

According to the embodiment described above, the effects listed below can be obtained.
(1) Communication with the outside is possible only when the mounted portion 11 is mounted on the user H. Therefore, in a situation where the user H is not using the communication terminal device 10, the communication terminal device 10 can be prevented from communicating with the outside.

(2) Compared with the configuration in which the antenna 21 is a coil having a spiral shape that rotates along the radial direction of the mounted portion 11, the antenna 21 can be easily formed on the mounted portion 11.
(3) When the mounted portion 11 is in a non-mounted state, the antenna 21 does not form a coil, and thus the antenna 21 cannot reliably communicate with the outside.

The embodiment described above can be implemented with appropriate modifications as follows.
[First Modification]
A first modification will be described with reference to FIGS. 5 and 6. In addition, the communication terminal device 10 of a 1st modification differs in the shape of the resin film 11c and the cover 11d compared with the communication terminal device 10 of embodiment.

On the other hand, the second mounting end portion 11b has a second step portion 11g formed by the antenna 21 and a laminate of the resin film 11c and the cover 11d.

  Therefore, when the mounted portion 11 is in the mounted state, the first step portion 11f and the second step portion 11g are fitted to each other. Therefore, the proximal end of the first wire member 41 and the distal end of the second wire member 42, the proximal end of the second wire member 42 and the distal end of the third wire member 43, and the proximal end of the third wire member 43 and the fourth end. Each of the ends of the wire members 44 has a portion overlapping each other along the extending direction. As a result, the proximal end of the first line member 41 and the distal end of the second line member 42, the proximal end of the second line member 42 and the distal end of the third line member 43, and the proximal end of the third line member 43 and the fourth end.

In FIG. 7, for convenience of illustration, a cover that covers one side surface of the resin film 11 c of the mounted portion 11 and the surface on which the antenna 21 is located is omitted. 8A is an enlarged view of the area A surrounded by the one-dot chain line in FIG. 7, and FIG. 8B is an enlarged view of the area B surrounded by the one-dot chain line in FIG. It shows.

As shown in FIG. 7, the antenna 21 includes a first line member 51, a second line member 52, a third line member 53, and a fourth line member 54.

Each of the second line member 52, the third line member 53, and the fourth line member 54 is also composed of two line members, like the first line member 51. 8B, the base end of the fourth line member 54 is not connected to the RF chip 22, and each of the two line members constituting the fourth line member 54 is not connected to the base end. Are connected to each other.

Therefore, according to the antenna 21 of the second modified example, even if the area occupied by the antenna 21 in the communication terminal device 10 is the same, the length of the antenna 21 can be almost doubled.
[Third Modification]
A third modification will be described with reference to FIGS. Note that the communication terminal device 10 according to the third modified example is different from the communication terminal device 10 according to the embodiment in the shape of the mounted portion and the shape of the antenna located inside the mounted portion. Therefore, in the following, such differences will be described in detail, and description of other configurations will be omitted. Further, in FIG. 10, for convenience of illustration, illustration of a cover that covers one side surface of the resin film of the mounted portion and on which the antenna is located is omitted.

As shown in FIG. 9, when the mounted portion 61 is in the mounted state, the first mounting end portion 61a and the second mounting end portion 61b are fitted together in the width direction to form an annular shape. Yes.
As shown in FIG. 10, the mounted portion 61 includes a resin film 62 and a cover 63 that covers two side surfaces of the resin film 62. Of the two end portions of the resin film 62, the first projecting portion 62a is provided at one end portion, and the second projecting portion 62b is provided at the other end portion. The first protrusion 62a and the second protrusion 62b do not overlap each other in the width direction, and the protrusion amount in the extending direction and the protrusion width in the width direction are equal to each other. Therefore, when the mounted portion 61 is in the mounted state, the first mounting end portion 61a and the second mounting end portion 61b are fitted to each other in the width direction.

  The antenna 70 includes a first line member 71, a second line member 72, a third line member 73, and a fourth line member 74, and each line member extends along the extending direction. In the first line member 71, the base end is located at the first contact edge 62c, which is a part in contact with the edge of the second protrusion 62b in the mounted state, among the edges of the first protrusion 62a, and the tip is RF. It is connected to the chip 22. The base end of the first wire member 71 is a first base end 70a1.

  In the second wire member 72, the base end is connected to the RF chip 22, and the tip is a second contact that is a part of the edge of the second protrusion 62 b that is in contact with the edge of the first protrusion 62 a in the mounted state. Located at edge 62d. The tip of the second wire member 72 is the first tip 70b1.

  In the 3rd line member 73, while a base end is located in the 1st contact edge 62c of the 1st protrusion part 62a, a front-end | tip is located in the 2nd contact edge 62d of the 2nd protrusion part 62b. The proximal end of the third wire member 73 is the second proximal end 70a2, and the distal end of the third wire member 73 is the second distal end 70b2.

  In the fourth line member 74, the proximal end is located at the first contact edge 62c of the first protrusion 62a, and the distal end is located at the second contact edge 62d of the second protrusion 62b. The proximal end of the fourth wire member 74 is the third proximal end 70a3, and the distal end of the fourth wire member 74 is the third distal end 70b3.

  In the first contact edge 62c of the first protrusion 62a, the first base end 70a1, the second base end 70a2, and the third base end 70a3 are arranged in order from the side close to the second protrusion 62b in the extending direction. Yes. At the second contact edge 62d of the second protrusion 62b, the first tip 70b1, the second tip 70b2, and the second tip 70b2 are arranged in order from the side close to the first protrusion 62a in the extending direction.

  When the mounted portion 61 is in the mounted state, the first contact edge 62c and the second contact edge 62d are in contact with each other. Accordingly, in the antenna 70, the first base end 70a1 and the third tip 70b3, the second base end 70a2 and the second tip 70b2, and the third base end 70a3 and the first tip 70b1 are in contact with each other. As a result, the antenna 70 forms a coil antenna having three turns, and the conduction state of the antenna 70 changes from the communication disabled state to the communication enabled state.

[Fourth Modification]
A fourth modification will be described with reference to FIGS. 11 and 12. The communication terminal device 10 according to the fourth modified example is different from the communication terminal device 10 according to the embodiment in that the communication terminal device 10 includes a communication antenna and two electromagnetic coupling coils. Therefore, in the following, such differences will be described in detail, and description of other configurations will be omitted.

  As shown in FIG. 11, the communication terminal device 10 includes a first coupling coil 81, a second coupling coil 83, and a communication antenna 84, and the first coupling coil 81 is connected to the RF chip 82, and the communication antenna 84 is connected to the second coupling coil 83. Each of the first coupling coil 81 and the second coupling coil 83 is located inside the mounted portion 11 and has the same spiral shape as the first plane where the first coupling coil 81 having the spiral shape is located. The second plane on which the second coupling coil 83 is located is parallel to each other. The distance between the first coupling coil 81 and the second coupling coil 83 in the direction in which the first coupling coil 81 and the second coupling coil 83 overlap is the same as the distance between the first coupling coil 81 and the second coupling coil 81 when a magnetic field is supplied from the outside. This is the distance at which the coupling coil 83 can be electromagnetically coupled.

  The first plane where the first coupling coil 81 is located and the second plane where the second coupling coil 83 is located are preferably parallel to each other, and the first plane and the second plane are the first coupling. A predetermined angle may be formed as long as the coil 81 and the second coupling coil 83 can be electromagnetically coupled.

  The communication antenna 84 receives information signals from the outside and transmits information signals of the RF chip 82. When the mounted portion 11 is in the mounted state, the communication antenna 84 forms one coil. That is, when the mounted portion 11 is in the mounted state, the communication antenna 84 is in a communicable state.

  When the mounted portion 11 is in a mounted state and a magnetic field is supplied from the outside to the communication terminal device 10, the first coupling coil 81 and the second coupling coil 83 are electromagnetically coupled. Thereby, the communication terminal device 10 transmits the information signal of the RF chip 82 to the outside through the first coupling coil 81, the second coupling coil 83, and the communication antenna 84 in this order. On the other hand, the communication terminal apparatus 10 receives information signals from the outside via the communication antenna 84, the second coupling coil 83, and the first coupling coil 81 in this order.

  As shown in FIG. 12, when the mounted portion 11 is in a non-mounted state, the communication antenna 84 is configured by a line member extending along the extending direction of the mounted portion 11, similar to the antenna 21 of the embodiment. Does not form a coil. That is, when the mounted portion 11 is in a non-mounted state, the communication antenna 84 is in a communication disabled state. Therefore, the communication antenna 84 changes the conduction state between the communicable state and the incommunicable state as the shape of the mounted portion 11 changes between the mounted state and the non-mounted state, and When the mounted part 11 is in the mounted state, the communication is possible, and when the mounted part 11 is in the non-mounted state, the communication is not possible.

  In addition, it is preferable that the member comprised from a ferrite is located in the site | part enclosed by the 1st coupling coil 81 or the site | part enclosed by the 2nd coupling coil 83. FIG. Accordingly, the magnetic flux passing through the space surrounded by the communication antenna 84 and the magnetic flux passing through the space surrounded by each coupling coil have directivity, so that the space surrounded by the communication antenna 84 and each coupling coil surround. Magnetic flux is easily held in each of the spaces.
