Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card type portable information communication terminal that allows unspecified number of people who are in close proximity to exchange mail.

[0002]

Recently, an increasing number of people are using a dating site on the Internet or the like to seek a relationship with a stranger. However, such a site has troublesome procedures such as application for members and detailed entry of their profile, and it takes time to find a contact person. Also, even if I exchange emails, I am worried about dating a person who does not have a face, and even when I actually meet, I sometimes end up disappointed.

[0003] On the other hand, there are some people who apply for dating by directly speaking when they find a person they like in the hall, but since they have considerable confidence and courage, they are not familiar with ordinary people. Also, not all people ask for a meeting, so even if you call out innocently, the probability of hitting is low, and the other person will also be annoying.

[0004] Therefore, the present invention is intended to provide an information tool that allows people who have been seeking a contact to feel free to contact each other on the spot without having to speak to each other.

[0005]

In order to achieve the above object, the present invention has the following constitution.

That is, according to the first aspect of the invention, a liquid crystal display provided with a touch panel and a wireless card having a semiconductor chip and an antenna are integrally laminated so that an unspecified number of people who are in close proximity are wireless. It is an e-mail exchange card that enables you to exchange e-mails at. The invention of claim 2 is the mail exchange card according to claim 1, wherein the sender's ID is marked on the back surface of the card.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of a mail exchange card embodying the present invention. In the mail exchange card, the wireless card 3 having the IC chip 1 and the loop antenna 2 embedded therein is connected to the liquid crystal panel 4, and the power generated by the solar cell 5 is temporarily stored in the card type battery 6 and, if necessary, It is supplied to the liquid crystal panel 4 and the wireless card 3. Then, as shown in FIG. 2, the liquid crystal panel 4 is arranged in the first layer on the surface, and the solar cell 5, the card type battery 6, and the wireless card 3 are sequentially laminated thereunder. When using this card, IDs such as initials and nicknames for identifying the sender of the mail shall be marked on the back side of the card.

As shown in FIG. 3, the IC chip 1 includes a panel control circuit 11 for controlling input / output of the liquid crystal panel 4, a memory circuit 12 for storing data and programs, and data for controlling bidirectional data communication. A control circuit 13, a transmission circuit 14 that modulates transmission data of a digital signal and outputs a modulated wave of an analog signal, and a reception circuit 15 that demodulates a reception wave of an analog signal and extracts reception data of a digital signal.
And a built-in antenna duplexer 16 for simultaneous transmission and reception, and the antenna duplexer 16 is connected to the loop antenna 2. This makes it possible to exchange wireless e-mail with a person in close proximity.

The liquid crystal panel 4 has a surface coated with a transparent electrode to form a touch panel, and is configured to allow screen input. Thereby, the mail to be transmitted is input through the touch panel and the received mail is displayed on the liquid crystal panel 4.

Further, a reflection type color TFT display is used, and a semitransparent reflection sheet is laid on the lower surface, and light hit from above passes through the liquid crystal and is reflected by the semitransparent reflection sheet on the bottom surface. Use it to make the display visible.
Further, the light shining from above passes through the liquid crystal panel 1 and the semitransparent reflection sheet and reaches the solar cell unit 2 spread on the bottom surface. Furthermore, a polymer film is used as a substrate, and it has a light and thin structure that is resistant to impact.

The solar cell 5 is an amorphous Si solar cell capable of forming a transparent solar cell, or a print type CdS / C which is less susceptible to deterioration by sunlight and can be used outdoors.
dTe solar cells are used.

As the card type battery 6, a paper battery, a sheet battery or a film battery having a thickness of about 1 mm is used.

The mail exchange card is a portable information terminal (PD
It goes without saying that any portable information device having a communication function and a liquid crystal display such as A) or a handheld PC (HPC) may be used.

The mail exchange card embodying the present invention is constructed as described above, and the sender of the mail operates the liquid crystal panel 4 to input his / her ID, profile, conditions of the contact person, etc. It operates and emits radio waves,
Send an email to an unspecified number of people within close range.
The person who receives the email compares the ID of the sender with the ID on the back of the card of a person who has a card around him, knows who is the sender, and specifies the actual person. And if you like the actual person and profile,
Reply to the email or go directly to the person and talk.

[0016]

As described above, the mail exchange card of the present invention enables an unspecified number of people who are in close proximity to exchange mail wirelessly. Therefore, according to the present invention, unlike a dating site where it takes time to meet each other, negotiation is immediately established if the user confirms and likes the other party on the spot, which matches the modern feeling that speed is required. . Also, since only those who ask for a meeting will participate, there is a high probability that they will succeed, and it will not bother other people. Therefore, a new business model can be constructed, for example, by distributing these cards to women free of charge on the market and selling them to men for a fee.
