In order to clarify the correspondence between each means of the invention described in the claims and the following embodiments, each means is described. When the features of the present invention are described by adding the corresponding embodiment (however, an example) in parentheses after the parentheses, the result is as follows. However, of course, this description does not mean that each means is limited to those described.

A tag according to a first aspect of the present invention is a tag attached to an information storage medium, in which a transmitting / receiving means for transmitting / receiving information (for example, the antenna 2 in FIG. 3) and information received by the transmitting / receiving means are stored. A storage unit (for example, the communication IC 26 in FIG. 3) and a display unit (for example, the liquid crystal display unit 1 in FIG. 3) around which the transmission and reception unit is arranged to display the information stored by the storage unit. It is characterized by having.

FIG. 1 is a front view showing the external structure of a tag to which the present invention is applied. The tag 10 of FIG. 1 has a configuration having a liquid crystal display unit 1 on its surface.

FIG. 2 is a front view showing an example of the internal structure of the tag 10 shown in FIG. 1, and FIG. 3 is a sectional view taken along line AA '. The tag 10 has a structure in which the liquid crystal display unit 1 is disposed between an upper substrate 21 and a lower substrate 22.

The upper substrate 21 is made of a transparent plastic, and the lower substrate 22 is made of an opaque plastic. The lower substrate 22 is provided with a concave portion 22A, and a liquid crystal circuit substrate 23 is embedded in the concave portion 22A.

The liquid crystal display section 1 has a structure in which a liquid crystal 1c is sealed from the surroundings between a liquid crystal upper substrate 1a and a liquid crystal lower substrate 1b by a liquid crystal sealing material 1d. LCD substrate 1a
, A polarizing plate (not shown) is provided. Also,
A reflection plate (not shown) is provided outside the lower liquid crystal substrate 1b.

On the liquid crystal circuit board 23, a segment liquid crystal circuit board 24a and a common liquid crystal circuit board 24b are formed along the vertical direction and the horizontal direction in FIG. This segment liquid crystal circuit board 24
a and the common liquid crystal circuit board 24b are both formed of plastic. Segment liquid crystal circuit board 2
A liquid crystal tab 25 is formed on 4a and on the common liquid crystal circuit board 24b.

An antenna 2 is wired below the upper substrate 21 so as to surround the outer periphery of the liquid crystal display unit 1. A communication IC 26 is formed below the upper substrate 21, and is connected to the antenna 2. Upper substrate 2
A card sealing material 27 is buried in the gap between the liquid crystal display unit 1 between the first substrate 1 and the lower substrate 22.

The entirety of such a tag 10 is flexible, and the lower substrate 22 is attached to, for example, a video cassette tape via a double-sided tape (not shown). When the video cassette is mounted on a video cassette tape recorder (both not shown), the video cassette recorder transmits and receives information to and from the tag 10 without contact.

The antenna 2 transmits and receives information to and from a video cassette recorder. The communication IC 26 stores the received information in the internal nonvolatile memory and transmits the information to the liquid crystal tab 25. The liquid crystal tab 25 drives the liquid crystal display unit 1 to display the transmitted information. The user transfers the information displayed on the liquid crystal display unit 1 to the transparent upper substrate 2.
1 can be read.

Therefore, when the title of the program stored on the video tape is stored in the communication IC 26, it is displayed on the liquid crystal display unit 1. Although not shown, the tag 10 has a built-in rechargeable battery. Therefore, the display is continued even after the video cassette is removed from the video cassette recorder, so that the user can decode the video cassette at any time.

As described above, according to the tag 10, since the liquid crystal display unit 1 is provided, information can be easily read.

Since the upper substrate 21, the lower substrate 22, the liquid crystal circuit substrate 23, and the liquid crystal circuit substrate 24 are made of plastic, they can be curved and hardly broken. Further, the weight of the tag 10 can be reduced, the cost can be reduced, and the tag 10 can be recycled.

In the above description, the liquid crystal display unit 1 has a structure in which the liquid crystal display unit 1 is covered with the transparent upper substrate 21, but may have a structure in which the liquid crystal display unit 1 is exposed on the surface.

FIG. 4 is a sectional view showing another example of the configuration of the tag 10 to which the present invention is applied. The difference between the tag 10 of FIG. 4 and the tag 10 of FIG. 3 is that the upper substrate 21 and the lower substrate 22 are removed and the antenna 2 is wired on the liquid crystal circuit substrate 23.

As described above, according to the tag 10 of FIG.
Antenna 2 and communication IC 26 on liquid crystal circuit board 24
The wiring board for the antenna 2 is omitted, and the antenna 2
And the substrate of the communication IC 26 are shared, so that the liquid crystal display unit 1 can be made large and the tag 10 can be used.
Can be made thinner, and the size can be made smaller.

FIG. 5A shows a tag 10 to which the present invention is applied.
FIG. 5B is a cross-sectional view showing still another configuration example of FIG.
Is an enlarged view of the main part. Tag 10 of FIG. 5 and FIG.
4 is that the antenna 2 is wired on the lower liquid crystal substrate 1b.

A liquid crystal display 1 is provided on the lower liquid crystal substrate 1b, and a liquid crystal circuit board 24 is provided on a side of the lower liquid crystal substrate 1b. The liquid crystal display unit 1 includes a liquid crystal upper substrate 1a, a liquid crystal lower substrate 1b, and a liquid crystal 1c, like the tag 10 of FIGS.
Are sealed between the upper liquid crystal substrate 1a and the lower liquid crystal substrate Ib by a liquid crystal sealing material 1d. FIG.
As shown in (B), ITO (I
ndium Tin Oxide) electrode 28 and antenna 2 are sequentially stacked. A coating material 29 is formed between the ITO electrode 28 and the antenna 2, and a part of the ITO electrode 28 is covered with the coating material 29.
Thereby, a short circuit between the ITO electrode 28 and the antenna 2 can be prevented.

As described above, according to the tag 10 of FIG.
Since the antenna 2 is wired on the lower liquid crystal substrate 1b, it is not necessary to increase the size of the liquid crystal circuit board 24 for the wiring of the antenna 2, and the size of the liquid crystal circuit board 24 can be reduced. Further, the tag 10 can be made light and thin.

The tag 10 shown in FIG. 5 corresponds to the tag 10 shown in FIGS.
