EXAMPLE FIG. 1 shows an outline of the information terminal device shown in this example. The information terminal device shown in this embodiment is connected to a network and has a function of drawing out necessary information from the network.

A high-performance central processing unit represented by RISC is adopted as the CPU used in the configuration shown in this embodiment.

FIG. 2 shows the appearance of the terminal device shown in this embodiment. Further, FIG. 3 shows a block diagram of the outline.

In FIG. 3, 1 is a CPU board,
Necessary arithmetic processing is performed. In addition, various necessary controls are performed. Reference numeral 2 is a CDROM in which necessary information is stored. A floppy disk device 3 has a function of calling out information from the floppy disk, and vice versa.

A hard disk 4 is used for reading and writing necessary information. Reference numerals 5 and 6 are speakers from which necessary audio information is output. A microphone 7 is used to input necessary voice information from here.

As a storage device, it is also useful to have a DVD in addition to a floppy disk and a hard disk. Further, it is useful to provide a keyboard, a mouse, a doublet, a pen mouse, and an image scanner as information input means and operation means. Further, a printer may be provided. Further, it may be configured such that a necessary information input / output unit is provided and information is exchanged with an external device.

As a method of exchanging information via a network, it is also useful to provide an audio signal input / output device for connecting to a telephone in consideration of the case of using a telephone line. Further, for that purpose, and in order to exchange voice signals, a DA-AD converter is required.

Further, the main body of the apparatus can be used as a telephone or a FAX.

A dedicated line dedicated to the network is arranged,
You may communicate. An example of the network is shown in FIG.

The image data to be displayed is processed by the graphic accelerator, the image memory, and the LCD control circuit, and the required image is displayed.

That is, the control signals such as the image data, the synchronizing signal, and the operation clock are converted into a predetermined voltage level by the level shift circuit at the output stage of the LCD control circuit, and further the electric field required in a predetermined area of the liquid crystal. Is added. Then, the image is displayed.

The size of the screen can be set to a required size, but it is suitable to be about 19 to 22 inches.

Input from a keyboard or doublet, data taken in from a network or an external peripheral circuit device, the processing progress of the CPU, etc. are displayed using a liquid crystal panel.

The display of an image has a form in which it is projected on a screen using a liquid crystal panel integrated as shown in FIG. With such a structure, the entire structure can be downsized. Further, the weight can be reduced.

If a CPU-embedded ASIC is used, the CPU processing allows the graphic accelerator function of the image control LCD controller to start, the modem function,
Further, the network interface function can be integrated into one chip.

Therefore, the configuration actually required is only the buffer and the circuit for level conversion, and the parts and manufacturing cost can be reduced.

When handling a moving image, it may be possible to use dedicated hardware. As for software, since it is used via the network,
It is desirable to have a security function that does not depend on the model or OS.

As software, SUN Micr
It is conceivable to access the network with an application (HotJava or the like) written in the JAVA language of OSSYSTEMS. As a result, it is possible to use a number of functions that have not existed in conventional information terminals.

The function of the information terminal device shown here is as follows.
It has a document creation function and a character recognition function by inputting a pen mouse from the doublet, and through a telephone line, ISDN line, leased line (LAN, ATM),

1. Acquires arbitrary information. Newspapers, teletexts, timetables (trains, buses, ships, planes),
Holiday medical period information, telephone number, public facility information, specialized data, event information, weather forecast, traffic information, book information, commercial advertisement, etc.

2. Shopping, bank deposit and balance inquiry, arrangement of tickets for vehicles, movies and concerts.

3. Send and receive email

4. File delivery

5. Telephone / Fax transmission / reception

Such can be done. In particular, for telephone / fax transmission / reception, a videophone can be realized by using a CCD camera.
