Further, unless otherwise specified, the drawings are schematic diagrams drawn to facilitate understanding of the present invention.

FIG. 1 is a perspective view of an RF-tagged copy slip 1 according to the present embodiment. The RF-tagged copy slip 1 according to the present embodiment includes a filling sheet 12 serving as the front surface, a pressure-sensitive transfer conductive layer 13 having pressure-sensitive transferability and conductivity, and a pair of radiation plates 102 that are shorter in width than the writing sheet 12. The RF tag sheet 10 has an RF tag 100 mounted thereon, and an image receiving sheet 14 onto which the contents written on the entry sheet 12 are transferred. Further, in the RF-tagged copy slip 1 according to the present embodiment, a pressure-sensitive transfer conductive layer 13 is formed between the entry sheet 12 and the image-receiving sheet 14, and the radiation plate 102 of one of the RF tags 100 serves as an insulating layer. The RF tag sheet 10 is provided so as to overlap the pressure-sensitive transfer conductive layer 13 through at least the adhesive layer, one radiation plate 102 is capacitively coupled to the pressure-sensitive transfer conductive layer 13, and the pressure-sensitive transfer conductive layer 13 is attached to the RF tag. It is configured to be used as 100 antenna elements.

In the RF tagged copy slip 1 according to the present embodiment, the width of the RF tag sheet 10 is shorter than that of the entry sheet 12, and the RF tag sheet 10 has its left end aligned with the left end of the entry sheet 12. It is pasted on the surface of the entry sheet 12 in this state. An entry column 120 is provided on the surface of the entry sheet 12 that does not overlap with the RF tag sheet 10, and in the RF tag 100 mounted on the RF tag sheet 10, the pair of radiation plates 102 are arranged side by side. .

The pressure-sensitive transfer conductive layer 13 is placed between the entry sheet 12 and the image-receiving sheet 14 by spanning from the boundary between one of the inner radiation plates 102 (here, the right radiation plate 102a) and the impedance matching circuit 103 to the entry field 120. The RF tag sheet 10 is pasted on the surface of the entry sheet 12 so that the radiation plate 102a of the RF tag 100 overlaps the pressure-sensitive transfer conductive layer 13 via an adhesive layer serving as an insulating layer. There is.

FIG. 2 is a diagram illustrating the layered structure of the RF tagged copy slip 1 according to the present embodiment. As illustrated in FIG. 2, the RF tagged copy slip 1 according to the present embodiment includes an RF tag sheet 10, an adhesive layer for adhering the RF tag sheet 10 and a predetermined sheet (here, the entry sheet 12). It has a structure in which a first adhesive layer 11, a writing sheet 12, a pressure-sensitive transfer conductive layer 13, and an image-receiving sheet 14 are laminated. As illustrated in FIG. 2, in the RF-tagged copy slip 1 according to the present embodiment, the RF tag sheet 10 and the entry sheet 12 are adhered to each other via the first adhesive layer 11, and the entry sheet 12 and the image-receiving sheet 14 are attached to each other through the first adhesive layer 11. 3 are adhered via adhesive layer 15.

For the entry sheet 12 and the image receiving sheet 14, paper used for general copying slips can be used. To form the first adhesive layer 11 for adhering the RF tag sheet 10 and a predetermined sheet, an acrylic adhesive, a rubber adhesive, a silicone adhesive, or the like can be used. Note that an adhesive may be used to form the first adhesive layer 11 instead of the adhesive.

The pressure-sensitive transfer conductive layer 13 not only has pressure-sensitive transfer properties for transferring characters written in the entry field 120 of the entry sheet 12 onto the image-receiving sheet 14, but also has conductivity to the extent that it can be used as an antenna element of the RF tag 100. It becomes a thin layer. Note that in consideration of use as an antenna element of the RF tag 100, it is preferable that the resistance value of the pressure-sensitive transfer conductive layer 13 is 100 Ω/sq or less.

In typical copy slips, carbon ink or color formers/developers are used in the pressure-sensitive transfer layer. If carbon ink with a resistance value of 100 Ω/sq or less is used to form the pressure-sensitive transfer conductive layer 13, the pressure-sensitive transfer conductive layer 13 can be formed only with the carbon ink layer formed on the back surface of the writing sheet 12. When a color forming agent/developer is used to form the pressure-sensitive transfer conductive layer 13, the resistance value of the color forming agent applied to the back side of the entry sheet 12 often exceeds 100Ω/sq. Formation requires a layer using conductive ink in addition to a coloring agent and developer.

FIG. 3 is a diagram illustrating the pressure-sensitive transfer conductive layer 13 when a color former/developer is used. When a coloring agent/developer is used to form the pressure-sensitive transfer conductive layer 13, the pressure-sensitive transfer conductive layer 13 is formed on the back side of the entry sheet 12 according to the size of the pressure-sensitive transfer conductive layer 13, and has a resistance value of 100Ω. It is composed of at least three layers: a conductive ink layer 130 having a size of /sq or less, a color former layer 131 formed on the back surface of the conductive ink layer 130, and a color developer layer 132 formed on the surface of the image receiving sheet 14. In this case, the conductive ink layer 130 becomes a conductive layer used as the antenna element of the RF tag 100, and the color former layer 131 and the color developer layer 132 are entered in the entry field 120 of the entry sheet 12. This layer has pressure-sensitive transfer properties for transferring characters and the like onto the image-receiving sheet 14.

The RF tag sheet 10 has a structure in which a top sheet 107, a sheet that protects the IC chip 104 (here, the top sheet 107), a second adhesive layer 105 that adheres the RF tag 100, an RF tag 100, and a back sheet 106 are laminated. It has become. Plastic materials such as polyethylene terephthalate, polypropylene, or polyethylene may be used for the front sheet 107 and back sheet 106 of the RF tag sheet 10, but considering that the present invention relates to a copy slip, it is preferable to use paper. is suitable.

There is. As a method for forming the antenna 101, etching using metal foil or printing using conductive ink can be used.

FIG. 5 is a diagram illustrating the positional relationship between the RF tag 100 and the pressure-sensitive transfer conductive layer 13. As described above, the RF tag 100 is arranged so that the right radiation plate 102a included in the antenna 101 overlaps the pressure-sensitive transfer conductive layer 13. The back sheet 106 of the RF tag sheet 10, the first adhesive layer 11, and the entry sheet 12 are present as insulating layers between the right radiation plate 102a and the pressure-sensitive transfer conductive layer 13, and the right radiation plate Since each of the radiating plate 102a and the pressure-sensitive transfer conductive layer 13 plays the role of a metal plate due to its shape, the radiation plate 102a included in the antenna 101 and the pressure-sensitive transfer conductive layer 13 are capacitively coupled.

If there is no capacitive coupling between the radiation plate 102a included in the antenna 101 and the pressure-sensitive transfer conductive layer 13, the pressure-sensitive transfer conductive layer 13 will not contribute to the communication distance of the RF tag 100; By capacitively coupling the pressure-sensitive transfer conductive layer 13, the pressure-sensitive transfer conductive layer 13 is electrically connected to the RF tag 100 and functions as an antenna element, so that the communication performance of the RF tag 100 can be improved.
