DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, reference numeral 20 denotes an IC memory tag with a bar code as an information storage medium according to the present invention, and a bar code label 13 having the same shape and the same area as the IC memory tag 10 is attached to the IC memory tag 10. It has an integrated structure adhered to the surface, and is used by being attached to a product 15 as a managed object.

The bar code label 13 has a paper-like label printed with a binary code represented by a bold line, a thin line, and an interval between them. Can be recorded up to 32 [bytes].

The bar code printed on the bar code label 13 is optically read by a dedicated reader 18 as shown in FIG. 2, and the read data is connected to the reader 18. It is sent to a computer device (not shown). Thus, the computer device can extract various information on the product 15 from the database based on the data read from the barcode.

As shown in FIG. 3, the IC memory tag 10 has an antenna substrate 3 as a card-shaped medium in which a memory IC 6 is attached to the lower surface and an antenna wiring 7 having a predetermined pattern is connected to the memory IC 6. The coated paper 1 is provided at the center and is attached to the upper surface of the antenna substrate 3 via a pressure-sensitive adhesive 2.

Here, the reinforcing plate 4 is provided with a through hole 4A which is slightly larger than the memory IC 6 and formed higher than the memory IC 6 at a position facing the memory IC 6. Thereby, when the antenna substrate 3 and the reinforcing plate 4 are overlapped, the through holes 4A
The memory IC 6 is accommodated in the memory board 6, so that the memory IC 6 does not protrude from the surface of the reinforcing plate 4.

The bar code attached I thus formed
The release sheet 5 of the IC memory tag 10 is peeled off from the C memory tag 20, and the C memory tag 20 is adhered and fixed to the product 15 as a managed object via the pressure-sensitive adhesive 2. Incidentally, since the memory IC 6 has a recording capacity of 1 Kbyte, the IC memory tag 20 with a bar code has, for example, a manufacturing factory name, a manufacturing date, a distribution route, a shelf life, a production manager name, and various comments. Various information on the product 15 can be recorded.

Next, as shown in FIG. 4, a data recording and reading device 25 for reading data relating to the product 15 to which such an IC memory tag 20 with a bar code is attached or writing new data is provided with a reader. The writer module 9 and the reader / writer antenna board 8 are connected via a connector 13 and a harness 14.

The reader / writer module 9 supplies power to the bar-coded IC memory tag 20, analyzes data read from the bar-coded IC memory tag 20, and sends data to be written to the bar-coded IC memory tag 20. All the processing is executed via the reader / writer antenna board 8.

In actual data communication, first, the reader / writer antenna substrate 8 of the data recording / reading device 25 is positioned so as to face the IC memory tag 20 with a bar code. The data recording / reading device 25 is connected to the connector 13 by the AC power supply (not shown) of the reader / writer module 9.
And a reader / writer antenna board 8 via the harness 14
The magnetic field 11 is generated around the antenna pattern 12 by passing a current through the antenna pattern 12 having the predetermined pattern.

In the IC memory tag 20 with a bar code, an induced electromotive force is generated by receiving the magnetic field 11 generated around the antenna pattern 12 by the antenna wiring 7, and based on this, the memory IC 6 does not require a battery. And can be activated.

Subsequently, the data recording / reading device 25 changes the magnetic field by changing the amount of current flowing through the antenna pattern 12 of the reader / writer antenna substrate 8 to change the magnetic field on the antenna wiring 7 of the IC memory tag 20 with a bar code. To change the induced electromotive force, and thus data is written to and read from the memory IC 6.

In this case, data communication between the data recording / reading device 25 and the IC memory tag with bar code 20 is performed by the antenna pattern 12 of the reader / writer antenna substrate 8 and the antenna wiring of the IC memory tag with bar code 20. 7 is performed in a non-contact manner by utilizing electromagnetic coupling at a short distance from each other, so that communication can be performed between the reader / writer antenna substrate 8 and the IC memory tag 20 with a bar code unless a metal object exists. ing.
