Description

Antenna device, antenna sheet, antenna, non-contact data transceiver

technical field

The present invention relates to an antenna for an RFID communication device (for example, a non-contact data transmission and reception device).

Background technique

In recent years, RFID (Radio Frequency Identification: Radio Frequency Identification) has attracted attention as a system for identification management of commodities and social ITization/automation. A non-contact data transceiver using this RFID has an IC chip and an antenna for data processing, etc., and communicates with an external device through radio waves or electromagnetic waves. For example, when a radio wave (including a control signal) transmitted from an external device is received, an electromotive force is generated (induced) by the action of the antenna (antenna on the non-contact data transceiver side). The IC chip performs data processing in response to the control signal using the electromotive force, and transmits the processing result on a carrier wave from the antenna. The external device receives it to read the above-mentioned processing result.

It is expected that more functions will be required for this non-contact data transmission and reception body in the future, and a high-performance antenna is essential for realizing them. That is, an antenna capable of efficiently receiving radio waves from various directions is desired. In addition, the following documents are listed as known documents disclosing built-in antennas.

Patent Document 2: Japanese Patent Laid-Open No. 2004-260586 (publication date: September 16, 2004)

Patent Document 3: Japanese Patent Laid-Open No. 2000-339069 (publication date: June 6, 2000)

However, the two-dimensional antenna in Patent Document 1 needs to change the orientation of the antenna according to the direction of radio waves, which is very inconvenient. In addition, three-dimensional antennas as shown in Fig. 15(a) and (b) that can receive radio waves from multiple directions have also been proposed. For example, three conductor loops (X, Y, Z) are formed corresponding to the three directions, and are connected in parallel (see FIG. 15( a )) or in series (see FIG. 15( b )). However, there are problems in that the shape is complicated and the manufacturing cost is high. In addition, as shown in Fig. 15(a) and (b), there are loads of 4 sides in the length of the wire (in each wire loop) corresponding to each direction, and there are 12 sides of the antenna as a whole (the sum of X, Y, and Z). There is also a problem of a large power loss (that is, a decrease in the power that can be consumed by a circuit such as an IC chip) due to the load.

Detailed ways

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 14 .

[Embodiment 1]

FIG. 1 is a perspective view showing the configuration of a non-contact data transceiver according to this embodiment. As shown in the figure, the present non-contact data transmission and reception unit 2 has an antenna device and an IC chip (not shown). Antenna device is made up of antenna 4 and holding block 3, and antenna 4 has: the 1st lead part 5a, 5b (the 1st conductor part); The 2nd lead part 6a, 6b (the 2nd conductor part); And the 3rd lead part 7a, 7b (third conductor part). In the non-contact data transceiver 2, the first to third lead portions (5a, 5b, 6a, 6b, 7a, 7b) are ring-shaped and connected to an IC chip (not shown).

Here, the non-contact data transceiver 2 has an IC chip for data processing and the like, and an antenna 4, and communicates with an external device by radio waves or electromagnetic waves. For example, when a radio wave (including a control signal) transmitted from an external device is received, an electromotive force is generated (induced) by the action of the antenna (antenna on the non-contact data transceiver side). The IC chip performs data processing in response to the control signal using the electromotive force, and transmits the result of the processing on a carrier wave from the antenna 4 .

The holding block 3 is formed by molding polyimide or the like into a cuboid (for example, a cube), and holds the lead parts 5 to 7 in a wound state. The material should just be a material that does not block radio waves. Furthermore, an IC chip is provided on the holding block 3 . In addition, as shown in FIG. 1 , one vertex of the holding block 3 (cuboid) is defined as A, and three mutually perpendicular planes sharing the vertex A are defined as planes P, Q, and R. As shown in the figure, the normal directions of the planes P, Q, and R are referred to as z, y, and x directions, respectively.

Here, the first lead part 5 (5a, 5b) is arranged along the plane P (on the plane P), the second lead part 6 (6a, 6b) is arranged along the plane Q (on the plane Q), and the third lead part The parts 7 (7a, 7b) are arranged along the plane R (on the plane R). Furthermore, the first lead portions 5a and 5b are arranged in the vicinity of both sides of the plane P not including the vertex A, and are arranged substantially parallel to the sides. In addition, the second lead portions 6a, 6b are arranged in the vicinity of both sides of the plane Q not including the apex A, and are arranged approximately parallel to each side, and the third lead portions 7a, 7b are arranged near the two sides of the plane R not including the apex A, Arranged approximately parallel to each side. Therefore, if the holding block 3 is made of, for example, a cube, the antenna 4 is projected in any direction of x, y, and z in the figure, and the area enclosed by the projected figure is equal and nearly maximum. That is, according to the present antenna 4, radio waves (signals) from any direction can be received with high intensity, and the accuracy can be made uniform in each direction.

And, when comparing with the structure shown in Fig. 15 (a), (b), compared with the load that there are 12 sides in the antenna as a whole in this conventional structure, in this antenna 4, there are only 6 sides in the whole antenna. The load on the sides (first lead parts 5a, 5b; second lead parts 6a, 6b; third lead parts 7a, 7b). Therefore, the loss caused by the antenna can be halved, and the power that can be consumed by circuits such as IC chips can be increased.

In addition, this antenna 4 has a very simple structure in which the six sides are formed in a ring shape along planes P, Q, and R (three mutually perpendicular planes sharing one vertex A of a cuboid). Therefore, as described later, a three-dimensional structure can be easily formed from two-dimensional or one-dimensional components. Thereby, not only the manufacturing cost but also the storage/transportation cost can be significantly reduced.

The present antenna 4 can be constructed by winding a wire once as shown in FIG. 2( a ), or by winding it multiple times as shown in FIG. 2( b ). In either case, both ends of the wire are connected to the IC chip. When winding a plurality of times, it is assumed to be wound in the same direction (counterclockwise in the figure). In addition, as shown in FIG. 2( b ), in the case of winding multiple turns, each lead portion ( 5a / 5b , 6a / 6b , 7a / 7b ) is constituted by a plurality of lead wires.

In addition, it is preferable to form grooves or steps (refer to Fig. 7(a) and (b)) in advance on the position where each lead wire part is arranged on the holding block 3, so that the lead wire can be easily wound or can maintain a good winding state. . In addition, a guide portion for catching the wire may be provided at a corner portion where the direction of the wire changes. Moreover, without providing a guide part, it may be wound so that it may be hung on three vertexes which are diagonal to the vertex A of each surface (refer FIG.3(c)).

In addition, the IC chip may be provided on the surface of the holding member so as to be inserted into each lead portion as shown in position D1/D2 of FIG. 8, or may be installed inside the holding block 3 as shown in position D3. The connection between the antenna 4 and the IC chip uses ultrasonic welding or the like. Of course, any connection method can be used.

In addition, this non-contact data transceiver can also be configured as shown in Fig. 3(a). That is, in the non-contact data transceiver 2α, the first lead portion 5 is formed along the plane P (on the plane P), the second lead portion 6 is formed along the plane Q (on the plane Q), and the third lead portion 5 is formed along the plane P (on the plane P). 7 is arranged along plane R (on plane R). Furthermore, the first lead portion 5 is arranged along the diagonal line of the plane P not including the vertex A, the second lead portion 6 is arranged along the diagonal line of the plane Q not including the vertex A, and the third lead portion 7 is arranged along the plane Q. The diagonal configuration of R that does not contain vertex A.

In addition, the present non-contact data transceiver can also be configured as shown in FIG. 3(b). That is, in the non-contact data transceiver 2β, the first lead portion 5 is formed along the plane P (on the plane P), the second lead portion 6 is formed along the plane Q (on the plane Q), and the third lead portion 7 is arranged along plane R (on plane R). Moreover, the first lead portion 5 is arranged along a quarter-circle circumference of the plane P including the vertex A, and the second lead portion 6 is arranged along a quarter-circle circumference of the plane Q including the apex A, The third lead portion 7 is arranged along the circumference portion of the quarter circle including the vertex A of the plane R. As shown in FIG. In such a configuration, the areas enclosed by the projection diagrams of the antenna 4 in the x, y, and z directions are also equal, and the above-mentioned effects can be obtained.

In addition, the present non-contact data transmitting and receiving unit can also be configured as shown in FIG. 3(c). That is, in the non-contact data transceiver 2γ, the first lead portion 5 is arranged so as to be close to the diagonal corner of the vertex A from one of the two sides including the vertex A of the plane P (near the end of the side opposite to the vertex A). Bp and arrive at the other side of the two sides including the vertex A (near the edge end on the opposite side of the vertex A), the second lead portion 6 is arranged to be connected from one of the two sides including the vertex A of the plane Q (vertex A Near the edge end on the opposite side of the vertex A) close to the diagonal Bq of the vertex A and reaches the other side of the two sides containing the vertex A (near the edge end on the opposite side of the vertex A), and the third lead portion 7 is arranged to be viewed from the plane R One of the two sides containing vertex A (near the end of the opposite side of vertex A) is close to the diagonal Bp of vertex A and reaches the other side of the two sides containing vertex A (the side on the opposite side of vertex A near the end). Thus, the first lead part 5 can be arranged along the plane P, the second lead part 6 can be arranged along the plane Q, and the third lead part 7 can be arranged along the plane R, so that the first to third lead parts 5 to 7 can form ring shapes.

FIG. 9 shows an example of mounting the present non-contact data transceiver on an object. As shown in the figure, this non-contact data transceiver can be installed on the inner corner C1 of the box that packs the ID object, or it can be installed on both corners C1 and C2 (in this way, the receiving range becomes wider) . Of course, it can also be installed on the outside of the box, and can also be installed on an appropriate part of the cushioning material (for example, at the corner of expanded polystyrene) put in the packaging box together with the ID object. In addition, it can also be directly attached to the ID object. In addition, when it is directly attached to the outside of the box or to the ID object, it is preferable to have a structure like FIG. 4(a), (b) or FIG. 6(a), (b).

In addition, the non-contact data transmitter-receiver 2 operates as shown in FIG. 14 , for example. First, radio waves from the reader/writer are received by the antenna 4 (S1). Next, the IC chip is activated by the electromotive force generated by the resonance action (S2). Next, the information in the IC chip is read, and necessary processing is performed (S3). Next, a signal of the processing result is transmitted from the antenna 4 to the reader/writer (S4).

Here, the non-contact data transceiver 10 has an IC chip for data processing and the like, and an antenna 14, and communicates with an external device through radio waves or electromagnetic waves. For example, when a radio wave (including a control signal) transmitted from an external device is received, an electromotive force is generated (induced) by the action of the antenna (antenna on the non-contact data transceiver side). The IC chip performs data processing in response to the control signal by using the electromotive force, and transmits the processing result on a carrier wave from the antenna 14 .

The holding member 13 has three holding walls (Pw, Qw, Rw). The holding walls Pw, Qw, and Rw share the vertex A and are perpendicular to each other, and hold the respective lead portions 15 to 17 in a wound state.

The back surface (z-side surface) of Qw is arranged (on the back surface of Qw), and the third lead portion 17 (17a/17b) is arranged along the back surface (y-side surface) of the holding wall Rw (on the back surface of Rw) configuration. Furthermore, the first lead portions 15a and 15b are arranged in the vicinity of both sides not including the apex A on the rear surface of the holding wall Pw, and are arranged substantially parallel to the sides (15a is along the y direction, and 15b is along the z direction). In addition, the second lead portion 16a/16b is arranged in the vicinity of both sides not including the apex A on the back surface of the holding wall Qw, and is arranged approximately parallel to each side (16a is along the x direction, and 16b is along the y direction); the third lead portion 17a/17b are arranged in the vicinity of both sides not including the apex A on the rear surface of the holding wall Rw, and arranged approximately parallel to each side (17a is along the z direction, and 17b is along the x direction).

Therefore, if each holding wall is made as the same square shape, then the antenna 14 is projected to any direction of x, y, and z in the figure, the area of the projected figure can be equal and its area relative to the volume of the holding member 13 is maximum. That is, according to the present antenna 14, radio waves (signals) from any direction can be received with high intensity, and the accuracy can be made uniform in each direction.

In addition, in FIG. 15( a ), each lead portion is arranged on the back side of the holding wall, but it may also be arranged on each holding wall surface (that is, the surface on the x+ side of Pw, the y+ side of Qw) as shown in FIG. 4( b ). The surface of Rw, the surface on the z+ side of Rw) forms a certain lead part or all lead parts.

In addition, the non-contact data transmitter and receiver of this embodiment can be configured as shown in FIG. 5 .

In addition, a guide portion for catching the wire may be provided at a corner portion where the direction of the wire changes. In addition, without providing a guide part, it may be wound so as to hang on three vertexes that are diagonal to the vertex A on each surface.

The non-contact data transceiver 10 of this embodiment may be directly attached to the ID object, or may be attached to a packaging box (inside or outside) of the ID object. In addition, it can also be attached to an appropriate part (for example, the corner of expanded polystyrene) of the cushioning material put in the packing box together with the ID object.

Here, the non-contact data transceiver 20 has an IC chip for performing data processing and the like, and an antenna 24, and communicates with an external device through radio waves or electromagnetic waves. For example, when a radio wave (including a control signal) transmitted from an external device is received, an electromotive force is generated (induced) by the action of the antenna (antenna on the non-contact data transceiver side). The IC chip performs data processing in response to the control signal using the electromotive force, and transmits the processing result on a carrier wave from the antenna 24 .

The holding member 23 has a first holding frame member Pf (Pfa/Pfb), a second holding frame member Qf (Qfa/Qfb), and a third holding frame member Rf (Rfa/Rfb), and holds each lead portion 25 in a wound state. ~27. Each holding frame member may be formed of polyimide or the like. Furthermore, an IC chip is provided on the holding frame member 23 . In addition, as shown in FIG. 6( a ), three hypothetical planes (planes for illustration without substance) that are perpendicular to each other and have the same square shape and share a point A are defined as planes p, q, and r , and the normal directions of the planes p to r are respectively referred to as x, z, and y directions.

The first holding frame member Pf (Pfa/Pfb) is arranged along the plane p, the second holding frame member Qf (Qfa/Qfb) is arranged along the plane q, and the third holding frame member Rf (Rfa/Rfb) is arranged along the plane r . Further, the first holding frame members Pfa/Pfb are arranged in the vicinity of both sides of the plane p not including the apex A, and are arranged substantially parallel to the sides (25a is along the y direction, and 25b is along the z direction). In addition, the second holding frame member Qf (Qfa/Qfb) is arranged in the vicinity of both sides of the plane q not including the apex A, and is arranged approximately parallel to each side (26a is along the x direction, 26b is along the y direction), and the third holding frame member The frame member Rf (Rfa/Rfb) is arranged in the vicinity of both sides of the plane r not including the vertex A, and is arranged approximately parallel to each side (27a is along the z direction, 27b is along the x direction).

Furthermore, the first lead portion 25 (25a/25b) is arranged on the first holding frame member Pf (Pfa/Pfb), and the second lead portion 26 (26a/26b) is arranged on the second holding frame member Qf (Qfa/Qfb). Above, the third lead portion 27 (27a/27b) is disposed on the third holding frame member Rf (Rfa/Rfb).

Therefore, if the planes p to r have the same square shape, the antenna 24 can be projected in any direction of x, y, and z in the figure, and the area of the projected figure can be equal. Also, this area can be maximized with respect to the volume of the holding member 23 . That is, according to the present antenna 24, radio waves (signals) from any direction can be received with high intensity, and the accuracy can be made uniform in each direction.

In addition, it is preferable to form a groove (see FIG. 7( c )) in advance on each holding frame member at the position where each lead portion is arranged so that the lead wire can be wound easily or a good winding state can be maintained. In addition, a guide portion for catching the wire may be provided at a corner portion where the direction of the wire changes. In addition, without providing a guide part, it may be wound so as to hang on three vertexes that are diagonal to the vertex A on each surface.

In addition, the non-contact data transmitter and receiver of this embodiment can be configured as shown in FIG. 6( b ). That is, in the non-contact data transceiver 20α, the first lead portion 25 (25a/25b) is insert-molded inside the first holding frame member Pf (Pfa/Pfb); the second lead portion 26 (26a/26b) The insert molding is inside the second holding frame member Qf (Qfa/Qfb); the third lead portion 27 (27a/27b) is insert molding inside the third holding frame member Rf (Rfa/Rfb).

The non-contact data transceiver 20 of this embodiment may be directly attached to the ID object, or may be attached to a packaging box (inside or outside) of the ID object. In addition, it can also be attached to an appropriate part (for example, the corner of expanded polystyrene) of the cushioning material put in the packing box together with the ID object.

[Embodiment 4]

In this embodiment, the communication body sheet for constituting the non-contact data transceiver 10 (and 10a/10β) described in Embodiment 2 will be described. That is, a three-dimensional non-contact data transceiver can be formed by assembling two-dimensional communication sheets. Also, let the slice plane be the x-y plane, and let the direction perpendicular to the slice plane be the z direction.

As shown in FIG. 10( a ), the communication body sheet 30 is composed of four connected partial sheets 30p, 30q, 30r, and 30s (connecting sheets) sharing a vertex A, and each partial sheet has the same square shape. The partial sheets 30p, 30q, and 30r each have a first lead part 35 (35a/35b), a second lead part 36 (36a/36b), and a third lead part 37 (37a/37b). In addition, although not shown, an IC chip connected to the lead portion is provided on the communication body sheet 30 . The first to third lead portions 35 to 37 are connected to each other directly or via an IC chip. Moreover, the partial slices 30s and 30p are bordered by the line L1 passing through the point A; the partial slices 30p and 30q are bordered by the line L2 passing through the point A; the partial slices 30q and 30r are bordered by the line L3. adjacent. In addition, the boundary between the partial pieces 30r and 30s is cut.

Here, the first lead portion 35a/35b is disposed approximately parallel to each side (35a is along the y direction, and 35b is along the x direction) near both sides of the surface of the partial sheet 30p not including the apex A; 36a/36b are arranged in the vicinity of both sides not including the vertex A on the surface of the partial sheet 30q, and are arranged approximately parallel to each side (36a is along the x direction, 36b is along the y direction); The vicinities of the two sides of the back surface not including the vertex A are arranged approximately parallel to each side (37a is along the y direction, and 37b is along the x direction). A connection portion connected to the lead portion 35a is provided on the surface of the partial sheet 30s. This connecting portion corresponds to an extended portion obtained by slightly extending the first lead portion 35a toward the partial sheet 30s side. Moreover, the 2nd lead part 36b (partial sheet surface) and the 3rd lead part 37a (partial sheet back surface) are connected through the via hole H, for example.

This communication body 30 can be configured as the non-contact data transmission and reception body of the second embodiment by assembling, for example, as follows. First, the partial sheets 30q, 30r are bent (towards the paper surface side) so as to be parallel to the z direction (direction perpendicular to the sheets) using the line L2 and the cutting line as the folding lines. Next, the partial sheet 30r is bent so as to be perpendicular to the partial sheet 30q and the partial sheet 30p (so that the cutting line and the line L1 coincide) using the line L3 as a folding line. Next, the partial sheet 30s is superimposed on the partial sheet 30r using the line L1 as a folding line. Thus, the end G of the third lead portion 37b arranged on the back surface of the partial sheet 30r overlaps with the connecting portion arranged on the partial sheet 30s to form the antenna 14 in FIG. 4(b) and the like. That is, the partial piece 30p constitutes the holding wall Pw and the first lead portion 15 in FIG. The holding wall Rw and the 3rd lead part 17 in FIG. 4(b) etc. are shown.

The communication body sheet 30 can be deformed as shown in Fig. 10(b) and (c). That is, the partial sheet 30s in FIG. 10( a ) is formed into a small trapezoid like the sticking part 30t (connecting piece), and the connecting portion is arranged thereon (see FIG. 10( b )). Then, the antenna 14 is formed by overlapping the end G of the third lead portion 37b arranged on the back surface of the partial sheet 30r and the connection portion of the sticking portion 30t. In addition, 30t of sticking places may be a small shape slightly larger than a connection part (refer FIG.10(c)).

In addition, the communication body sheet of this embodiment may be configured as shown in FIG. 11( a ). The communication body sheet 40 is composed of four partial sheets 40p, 40q, 40r, and 40s (connecting sheets) that share a point A and are connected to each other, and each partial sheet has the same square shape. The partial sheets 40p, 40q, and 40r each have a first lead part 45 (45a/45b), a second lead part 46 (46a/46b), and a third lead part 47 (47a/47b). In addition, although not shown, an IC chip connected to the lead portion is provided on the communication body sheet 40 . The first to third lead portions 45 to 47 are connected to each other directly or via an IC chip. Moreover, the partial slices 40s and 40p are bordered by the line L1 passing through the point A; the partial slices 40p and 40q are bordered by the line L2 passing through the point A; the partial slices 40q and 40r are bordered by the line L3. Adjacent; the partial sheets 40r and 40s are adjacent to each other with the line L4 as the boundary. Let the diagonal line including A of the partial sheet 40s be a line L5.

Here, the first lead portion 45a/45b is arranged approximately parallel to each side (45a is along the y direction, and 45b is along the x direction) in the vicinity of both sides not including the vertex A on the surface of the partial sheet 40p; 46a/46b are arranged in the vicinity of both sides not including the vertex A on the surface of the partial sheet 40q, and are arranged approximately parallel to each side (46a is along the x direction, 46b is along the y direction); The vicinity of both sides of the surface not including the vertex A is arranged approximately parallel to each side (47a is along the y direction, and 47b is along the x direction). A connection portion i connected to the lead portion 45a is provided on the surface of the partial sheet 40s. This connecting portion i corresponds to an extended portion obtained by slightly extending the first lead portion 45a toward the partial sheet 40s side. Furthermore, a connection portion j connected to the lead portion 47b is provided on the surface of the partial sheet 40s. This connecting portion j corresponds to an extended portion obtained by slightly extending the third lead portion 47b toward the partial sheet 40s side.

The communication sheet 40 can be assembled, for example, in the following manner to constitute the non-contact data transceiver of the second embodiment. First, the partial sheets 40q and 40r are folded toward the back side of the paper so as to be parallel to the z direction (direction perpendicular to the sheets) using the lines L2 and L4 (one straight line) as folding lines. Next, the partial sheet 40s is folded inward using the line L5 as the folding line, and the partial sheet 40s is folded using the line L5 as the folding line so that the line L4 and the line L1 overlap. As a result, the connecting portion i and the connecting portion j arranged on the partial sheet 40s overlap to form the antenna 14 in FIG. 4( a ) or the like. That is, the partial piece 40p constitutes the holding wall Pw and the first lead portion 15 in FIG. The holding wall Qw and the second lead portion 16 in FIG. 4( a ) and the like.

The communication body sheet 40 can be constituted as in Fig. 11(b), that is, cut off the connection between the vicinity of the connection part i and A in Fig. 11(a), and cut off the connection between the vicinity of the connection part j and A, as shown in Fig. Notches are formed in the partial sheet 40s (connecting sheet) of I1(a).

In addition, the communication body sheet of this embodiment may be configured as shown in FIG. 12( a ). The communication body 50 is composed of four sub-pieces 50p, 50q, 50r, and 50s that share one point A and are connected to each other, and each sub-piece has the same square shape. The partial sheets 50p, 50q, and 50r each have a first lead part 55 (55a/55b), a second lead part 56 (56a/56b), and a third lead part 57 (57a/57b). In addition, although not shown, an IC chip connected to the lead portion is provided on the communication body sheet 50 . The first to third lead portions 55 to 57 are connected to each other directly or via an IC chip.

Adjacent; the partial sheets 50r and 50s are adjacent to each other with the line L4 as the boundary. Let the diagonal line including A of the partial sheet 50s be a line L5.

Here, the first lead portion 55a/55b is arranged approximately parallel to each side (55a is along the y direction, and 55b is along the x direction) in the vicinity of both sides not including the vertex A on the surface of the partial sheet 50p; 56a/56b are arranged in the vicinity of the two sides not including the vertex A on the surface of the partial sheet 50q, and are arranged approximately parallel to each side (56a is along the x direction, 56b is along the y direction); The vicinity of both sides of the surface not including the vertex A is arranged approximately parallel to each side (57a is along the y direction, and 57b is along the x direction).

Furthermore, a connecting portion k1 connected to the end F of the lead portion 55a is provided along the line L1 on the surface of the partial sheet 50p, and an end portion connected to the lead portion 57b is provided on the surface of the partial sheet 50r along the line L4. In the connection part k2 connected by G, these two connection parts k1 and k2 are connected in the vicinity of the vertex A.

The communication sheet 50 can be assembled, for example, in the following manner to constitute the non-contact data transceiver of the second embodiment. First, using line L2 and line L4 (one straight line) as a fold line, the partial sheets 50q and 50r are bent toward the back side of the paper so that they are parallel to the z direction (direction perpendicular to the sheet). Next, the partial sheet 50s is folded inward using the line L5 as the folding line, and the partial sheet 50r is folded using the line L3 as the folding line so that the partial sheet 50r is perpendicular to the partial sheet 50p and the partial sheet 50q.

In any of the above cases, the partial sheets 50q, 50r are bent toward the back side of the paper using the line L2 and the line L4 (one straight line) as the folding lines so that they are aligned with the z direction (direction perpendicular to the sheet). )parallel. Next, the partial sheet 50r is bent so that the partial sheet 50r is perpendicular to the partial sheet 50p and the partial sheet 50q using the line L3 as a folding line (so that L1 and L4 overlap). As a result, the end F of the lead portion 55a and the end G of the lead portion 57b are connected from the beginning by the connection portions k1, k2, thus forming the antenna 14 in FIG. 4(a) and the like.

In any of the above configurations, it is preferable to form an adhesive surface on at least a part of one or more partial sheets 50 so that it can be attached to a packaging box or the like of an ID object. In addition, the communication body sheet 50 of the present embodiment may be attached directly to the ID object, or may be attached to a packaging box (either inside or outside) of the ID object. In addition, it can also be attached to an appropriate part (for example, the corner of expanded polystyrene) of the cushioning material put in the packing box together with the ID object.

The communication body sheet according to the present embodiment includes an IC chip, but only the antenna (not including the IC chip) may be configured as an antenna sheet. In this case, for example, an IC chip may be provided after the antenna sheet is assembled. In addition, the antenna sheet may have the same configuration as those shown in FIGS. 10( a ) to ( c ) and FIGS. 11( a ) and (b).

[Embodiment 5]

Furthermore, in order to configure the non-contact data transceiver described in Embodiment 3, a communication ring as shown in FIG. 13( a ) may be configured. The communication body ring 60 has a structure in which six holding members 61a to 61f are attached to an annular lead portion 66 with intervals therebetween. In addition, although not shown, an IC chip connected to the wire part is provided on the communication body ring 60 . Here, the lead wire part 66 is easy to bend, and the holding member 61a-61f uses the material which does not bend easily. Accordingly, the communication body ring 60 can have the following three-dimensional structure. That is, planes p, q, r having the same square shape are set as mutually perpendicular imaginary planes sharing the vertex A, the holding members 61a, 61b are arranged along the plane p, the holding members 61c, 61d are arranged along the plane q, and the holding members 61a, 61b are arranged along the plane q. 61e, 61f are arranged along the plane r, and the holding members 61a/61b are arranged in the vicinity of both sides of the plane p not including the vertex A, and are arranged approximately parallel to each side; The vicinity of both sides of the vertex A is arranged substantially parallel to the sides; the holding members 61e/61f are arranged near the two sides of the plane r not including the vertex A and substantially parallel to the sides, and the conductive wire 66 passes through the holding members 61a ~61f and surround. With such a three-dimensional structure, it can be attached to an ID object (see FIG. 13(b)), and the effect described in Embodiment 3 can be obtained.

It is also possible to configure the communication body ring using only wires without using holding members such as 61a to 61f in FIG. 13( a ). In this case, folded lines or constricted portions are provided at multiple places of the lead portion. In addition, as the above-mentioned lead wire, a lead wire obtained by connecting a plurality of conductors having different flexibility may be used. Thus, deformation into the three-dimensional structure described above is possible. In addition, the conductive wire covered with the covering material may be formed into a loop to constitute the communication body loop. In this case, fold lines or constricted portions are provided at multiple places on the covering material. Moreover, the covering material which connected the several covering materials which differ in flexibility can also be used for this covering material. Thus, deformation into the three-dimensional structure described above is possible. Furthermore, it is also possible to add a fixing member that is not easy to bend to the loop-shaped uniform wire. In this case, for example, it is preferable to provide a protrusion or form a groove in the fixing member so that the lead wire does not deviate from the fixing member. This makes handling easier.

In addition, the communication body ring 60 of the present embodiment may be directly attached to the ID object, or may be attached to a packaging box (either inside or outside) of the ID object. In addition, it can also be attached to an appropriate part (for example, the corner of expanded polystyrene) of the cushioning material put in the packing box together with the ID object.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. Embodiments obtained by appropriately combining technical means disclosed in the embodiments are also included in the technical scope of the present invention.

The non-contact data transceiver of the present invention can be applied to equipment using RFID.
