BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on the illustrated embodiments.

FIG. 1 shows an example in which an equipment management electronic tag 20 is provided on an equipment (equipment tool equipment exceeding the limit of consumables) 10. Here, the equipment management electronic tag 20 is of a non-contact IC card type. Reference numeral 30 is a reader / writer that reads and records the equipment management electronic tag 20 in a contactless manner using radio waves.

FIG. 2 is a schematic diagram showing the structure of the equipment management electronic tag 20. In FIG. 2, reference numeral 21 is an antenna section for transmitting information and generating electromotive force, and 22 is a semiconductor chip (IC chip) having a recording section for recording information.
The semiconductor chip 22 has a function of recording information received from the antenna section 21 in its recording section or transmitting information from the recording section through the antenna section 21.

The antenna portion 21 and the semiconductor chip 22 are protected by a protective layer (not shown). Specifically, the antenna portion 21 and the semiconductor chip 22 are built in a sheet-shaped resin base material (not shown).
However, it is also possible to have a structure in which one side of a sheet-shaped resin base material is carried.

The attachment means of the equipment management electronic tag 20 to the equipment 10 is an adhesive in this example, and an adhesive is attached to the back surface of the equipment management electronic tag 20, that is, the back surface of the resin base material, Attachment is performed by sticking this on the surface of the equipment 10. However, depending on the type of the equipment 10, the equipment management electronic tag 20 may be provided inside the equipment 10.
The antenna part 21 and the semiconductor chip 22 may be built in.

Next, the operation will be described.

As described above, the equipment management electronic tags 20 are attached to the equipment 10, respectively. This equipment management electronic tag 20
, Management information such as the management number (reference number), location of use, manager (person in charge), usage status of the equipment 10,
Record in advance. Whenever the location of use of the equipment 10 is changed, the location of use after the change is recorded in the equipment management electronic tag 20.

The change of the place of use is automatically recorded in the equipment management electronic tag 20 by the reader / writer 30, and at the same time, recorded in the reader / writer 30. That is, the antenna section 21 of the equipment management electronic tag 20 receives a radio wave of a communication frequency of 125 kHz from the reader / writer 30 shown in FIG. 1 and generates electromotive force by electromagnetic induction, which is used as a driving power source for the semiconductor chip 22. The information of the calibration record supplied and simultaneously sent at the communication frequency of 125 kHz is received and transmitted to the semiconductor chip 22. The semiconductor chip 22 records the information of the calibration record received from the antenna unit 21 in the internal recording unit.

When the change of the place of use is recorded in advance in this way, the administrator can read the recorded contents of the equipment management electronic tag 20 by the reader / writer 30 and input the information into the host computer. Can immediately recognize where the equipment is currently being used. The contents recorded in the equipment management electronic tag 20 are read by the reader / writer 30 by the same operation as the recording of the above information.

Therefore, in the depreciation processing at the end of the fiscal year, which is performed once a year, the reader / writer 30 is brought close to the equipment management electronic tag 20 of each equipment 10 and the recorded contents are read. On the host computer side, for example, with respect to all the equipment of the entire factory, it is possible to easily confirm the actual use places of the equipment and grasp the use status of the equipment. Conventionally, based on the management number assigned to each equipment, the equipment and the management number are visually checked, and necessary information such as the location of use is manually recorded on a recording paper, and then manually input to an electronic file. However, when the equipment management electronic tag 20 is used, the data such as the actual use place can be electrically recorded on the spot, and the recorded information can be retrieved without error when necessary. It becomes possible.

In the above description, the communication frequency between the reader / writer 30 and the equipment management electronic tag 20 is 125 kHz, that is, the equipment management electronic tag 20 is 125 kHz.
The reason why the tag is configured to resonate at Hz is as follows.
That is, the fixture 10 may be composed of a conductor such as metal, and when the fixture management electronic tag 20 is attached to this, the magnetic field formed by the radio waves oscillated by the transmission / reception antenna of the reader / writer 30 will be Since it is canceled by the magnetic field resulting from the eddy current induced in the conductor, the equipment management electronic tag 20 may not be identified. A method of increasing the strength of the magnetic field weakened by the metal to the extent that the tag can be activated can be considered.
Since the output of the transmission / reception antenna of the writer 30 is regulated by various radio regulations, the strength of the magnetic field formed by the transmission / reception antenna cannot be increased. Therefore, even if the tag is arranged near the metal case or the like, 125 kHz is selected as the frequency with which the tag can be identified.

In the above embodiment, the equipment management electronic tag 20 is described as a card shape using a planar loop antenna. However, the equipment management electronic tag 20 of the present invention does not necessarily have to be in the shape of a card, and as shown in FIG. 3, an electronic tag using the antenna part 21 in which the winding antenna 24 is wound around the ferrite core 23. The electronic tag is superior in terms of downsizing.

The equipment management electronic tag 20 shown in FIG. 3 has a magnetic core 2 such as the ferrite core formed on the surface of a resin base material 25.
An antenna portion 21 composed of 3 and a winding antenna 24 and a semiconductor chip (bare chip) 22 are carried, both are electrically connected through a solder ball 26, and the whole is resin-molded 27. With this configuration, it is possible to create a highly sensitive small-sized equipment management electronic tag 20. The base material 25 made of resin is attached to the equipment 10.
It can be performed by attaching an adhesive to the back surface of the device and attaching it to an appropriate place of the equipment 10.
