First, a first example of an embodiment of the non-contact type data carrier device of the present invention will be described with reference to FIG.
A non-contact type data carrier device 10 of the first example is a card-type non-contact type data carrier device according to JIS standard ISO / IEC7810 ID-1 type, and is a small non-contact type 10 mm × 10 mm square or less. A plurality of formula data carriers are provided at positions separated from each other so as not to interfere with each other.
Each of the small non-contact data carriers 20 is fitted by a holder 30 that can be detached and attached so as to be detachable on the card surface.
The holder portion 30 of the present example is provided with a recess (a space portion of the base material corresponding to a region in which the space portion 35 and the holding member 30a are combined) shown in FIG. A holding member 30a for detachably holding a small non-contact type data carrier 20, which is different from the base material 10, is attached to accommodate the small non-contact type data carrier in the recess. .
The holder portion 30 is formed of an elastic body such as rubber and is held in the card base portion 11, and is a small non-contact type data carrier with the side surface side holding portion 31 and the surface side holding portion 32. The outer peripheral part of 20 is hold | maintained and fixed.
Fixing is performed by being sandwiched between the side support portions 31.

As described above, the non-contact type data carrier device 10 of the first example is 10 mm × 10 mm square which is extremely small as compared with the non-contact type data carrier used by being mounted on the conventional card-type non-contact type data carrier. By providing the following small non-contact data carrier 20, even if the card-type non-contact data carrier 10 is used in an overlapping manner, for example, as shown in FIG. 4, a card case (not shown) ) Etc., even if they are used repeatedly, the probability of interference between the non-contact data carriers 20 mounted and used on them can be made extremely low. In the first example, each small non-contact type data carrier 20 is fitted in a fitting holder 30 that can be detached and attached in a removable manner on the card surface. By inserting a small non-contact type data carrier different from the small non-contact type data carrier 20 disposed in the holder unit 30 into the holder unit 30, a card-size non-contact type data carrier device is provided. It is possible to have another function.
By appropriately selecting a small non-contact data carrier 20 to be attached and detached, the combination of functions can be freely changed.
Of course, by providing a plurality of small non-contact type data carriers 20, one non-contact type data carrier device of the first example can have desired different functions.

Further, in the conventional card-type non-contact type data carrier device, when a plurality of non-contact type data carriers are mounted on the data carrier, it is difficult to read only one by the reading device. However, when a small non-contact type data carrier of 10 mm × 10 mm size or less is used as in this example, the communication distance can be limited to be short, and the reading device can read only one. Become.
By using such a plurality of small non-contact data carriers 20, security can be improved when compared with a conventional card-type non-contact data carrier device.

  As the base material part 11, a known card base material such as polyethylene terephthalate resin (PET), amorphous polyester (PETG), polyvinyl chloride, polyethylene terephthalate and polycardinate, or polymer alloy of polyarylate is used. However, it is not limited to these.

A small non-contact type data carrier 20 is provided on a laminated wiring substrate 60 in which a base material in which a part of an antenna circuit portion is formed is laminated on the surface of each non-contact base material 51 as shown in FIG. Each layer is electrically connected through the through-hole 45 to form an antenna circuit portion, the IC chip 41 is mounted on the surface portion of the laminated wiring substrate 60, and the antenna circuit The portion 42 is electrically connected.
Here, the non-contact type data carrier 20 has rigidity as a whole and can maintain a sheet shape on a plane.
Here, the antenna circuit unit 42 has a four-layer spiral shape in which the number of turns of each layer is about nine. Examples of the size of the non-contact type data carrier unit 11 include a 5 mm square and a thickness of about 150 μm.
This size is much smaller than 54 mm × 85.6 mm which is a standard size for a card-type RFID tag (IC card).
The surface IC chip 41, bonding wire 48, and antenna circuit portion 42 are covered and protected by a solder resist 50 and a sealing resin 49.
The antenna coil of the antenna circuit section 42 has a line width of about 80 μm, a line width of about 70 μm, and a line thickness of about 18 μm, and can be formed in such a laminated structure by a known additive method or semi-additive method.
The IC chip 41 is mainly composed of a ROM, a RAM, a logic circuit, and a CPU. As the IC chip 41, a chip that is commercially available as a chip for a 13.56 MHz band RFID tag, such as an I-CODE SLI chip of Phillips, a my-d chip of Infineon Technology, or the like is appropriately selected according to the application. Use.
This non-contact type data carrier unit 11 conforms to the ISO 14443 proximity card standard.
In this example, the size of the non-contact data carrier 20 is not so large with respect to the size of the IC chip 41 to be mounted.
The shape does not necessarily have to be a square, but is rectangular in order to facilitate the production of multiple pieces.
In addition, by making the laminated wiring substrate 60 laminated into a substantially square shape, it becomes easy to secure the inner area of the antenna while reducing the size, and the inductance value of the coil can be improved.
The laminated wiring substrate 60 is, for example, a single-sided copper-clad substrate in which each layer is an insulating substrate having a thickness of 0.1 mm as a base 51 and a copper foil having a thickness of 18 μm is laminated on one side or both sides. Using a copper-clad substrate, the antenna circuit part 42 having a desired shape is formed by etching using a photoetching method for the outer layer and the inner layer, and each layer is heated and pressed through an insulating adhesive layer for lamination. Further, a through hole is formed and manufactured.
Here, through-holes are used for the connection between the layers, but a connection method called B ² it (which breaks through the insulating layer with conductive bumps) may be used.
Thereby, it is possible to reduce the total number of manufacturing steps.
