[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label type storage device which is used by attaching it to a recording / reproducing medium, for example.

[0002]

2. Description of the Related Art The above-mentioned information is recorded on a cassette tape so that information such as the contents of video data photographed by an imaging device such as a television camera and recorded on a video tape can be easily confirmed. There has been a demand for a technique of attaching a cassette label that can be used.

[0003] The applicant has previously filed an application for such a cassette label. As described in JP-A-10-208003, this cassette label secures the strength of the entire cassette label using a plastic material, and at the same time, has a surface having a surface roughness such that characters can be written thereon. The function of the conventional coated paper, reinforcing agent and IC protective agent is realized by this one member.

[0004] Since such a cassette label is not attached only to a cassette, in the present specification, the following will be described.
Call it a tag. FIG. 11 shows the above-mentioned JP-A-10-20800.
No. 3 discloses a structure of a conventional tag 110.
FIG. 12 shows the structure of a conventional antenna member.

Referring to FIGS. 11 and 12, an antenna member 100 includes a coil portion 101 forming an antenna inductance and a capacitor portion 102 having a three-layer structure.
03 is implemented.

Further, the antenna member 100 is reinforced with a plastic material 4, and one side of the plastic material 4 to be adhered to a recording / reproducing medium is covered with a double-sided adhesive 5 by a release paper 7, When attaching the tag 110 to the recording / reproducing medium, the tag 110 is attached to the recording / reproducing medium by peeling off the release paper 7 and using the double-sided adhesive 5.

The double-sided adhesive 5 of the plastic material 4
A double-sided adhesive 6 is applied to the plastic material 4 on the other surface side opposite to the surface on which the is adhered, that is, the surface which becomes the surface when adhered to the recording / reproducing medium. Is coated with a coated paper 8,
The entry surface is on the eight sides of the coated paper. As a result, the structure of the tag 110 has a seven-layer structure in total, and an eight-layer structure partially.

The antenna member 100 is made of a material having a certain dielectric constant, for example, polyimide, or a metal, for example,
The coil portion 101 is formed by etching, vapor deposition, or paste printing of copper, silver, aluminum, or the like, and a metal is further etched on the surface on which the coil portion 101 is formed and the surface opposite to this surface. Thus, the capacitor portion 102 is formed by sandwiching a material having a certain dielectric constant between both sides of the metal. The coil unit 1
01 and the capacitor section 102 are
05 and is tuned to the frequency at which the tag 110 operates.

[0009]

However, since the conventional tag 110 described above has a structure including a plurality of member layers, there is an inconvenience that member costs and manufacturing steps are complicated, and thus a completed product is required. The price of the tags was rising.

In particular, since the dielectric polyimide constituting the capacitor and coil of the antenna member 100 is expensive, it is disadvantageous to use it for a large area because the polyimide is expensive. The above-mentioned etching process has a disadvantage that a complicated process is required.

The present invention has been made in view of the above circumstances, and has as its object to provide a label-type storage device having a simple structure and a simplified manufacturing process.

[0012]

A label base having a surface on which arbitrary characters and figures can be written, and having a surface member attached to the plastic material so as to cover the integrated circuit, the antenna means, and the capacitor circuit; is there.

Therefore, according to the present invention, the following operations are performed. The coil part forming the antenna inductance of the antenna is formed directly on the plastic material, and the coil part and the capacitor part are connected at the joint. As a result, the structure of the label-type storage device (tag) can have a six-layer structure, one layer less than the conventional structure, and a partial seven-layer structure.

Here, since the induced current induced is proportional to the magnetic flux density passing through the open area of the coil section 2, when the capacitor section 102 is formed in the coil section 101 as in the conventional tag 110, The magnetic flux passing through the coil unit 101 is reduced by the area, and the communication distance between the tag 1 and the reader / writer 41 is shortened.

In the present embodiment, since the position of the capacitor portion 3 is different from the position of the coil portion 2 and is made of a different structure, it is configured outside the coil portion 2 to increase the magnetic flux density. As a result, the communication distance between the tag 1 and the reader / writer 41 can be improved to be longer.

Since the coil is composed of a label base having a structure to be formed, the capacitor part formed inside the coil part of the antenna is arranged outside the coil part, so the magnetic flux density passing through the coil part increases, and the electromagnetic induction causes Even if the power supply and the communication distance are extended, and the communication distance is increased, the power for electromagnetic induction is reduced, the same communication distance as before can be secured, and the power consumption can be reduced at the same time. This has the effect.

Further, in the label type storage device according to the present invention, in the above description, the capacitor circuit is configured such that a pair of conductors are arranged on both surfaces of a dielectric to form a capacitor portion, and the capacitor circuit is connected to the pair of conductors. Since the connection portion connected to the antenna means via the through hole is provided, it is possible to simplify the joining process of the capacitor portion to the coil portion of the antenna.

Further, in the label-type storage device of the present invention, in the above, a loop-shaped coil portion serving as the antenna means is formed on the plastic material, and the connection portion of the capacitor portion and the connection portion of the coil portion are connected to each other. Since it is composed of a label base having a structure to which the antenna is connected, there is no need to provide another process for increasing the accuracy of joining the coil portion and the capacitor portion of the antenna, and the positioning for joining is simplified. It has the effect of being able to do so.

Further, the label-type storage device according to the present invention is constituted by a label base having a structure in which the connection portion of the capacitor portion or the coil portion is connected to the integrated circuit. Alternatively, it is possible to mount an integrated circuit on the coil portion, and it is possible to increase the degree of freedom in design.
