Abstract

PURPOSE:To remarkably simplify an operation of a terminal equipment by providing a card write control part for writing information retrieving data in an integrated circuit card during executing an information retrieving data input routine. CONSTITUTION:In the input data writing routine 28, input data is written in an IC card by the IC card write control part 7, set to an IC card read control part 6 and a reset button of the terminal equipment is pressed, and then, a CPU 1 performs a program of a ROM 2. Based on the data of the IC card, an information center is called, a line is connected, a password is transmitted, a screen is automatically called out and renewed. After the information of the data of the IC card is retrieved, leading to a manual information retrieval routine, a screen which is not inputted previously can be retrieved freely manually. When a communication mode is selected without a card input, leading to a manual line connection routine, an information center number or the password is inputted one by one by an input operation through a keyboard 4. Thereby, a troublesome key operation is carried out to a minimum and the data can be read in a short time.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a system for inputting an integrated circuit card storing an information retrieval program into a data terminal on the user side to generate information retrieval data, which is retrieved from an information center. It relates to a data terminal device for inputting information.

[Conventional technology]

Videotex connects a general user equipped with a user terminal and an information center with an image information database using a public telephone line, and the user obtains image information from the information center via the public telephone line. The user installs a terminal device and uses the numeric keypad or alphanumeric keyboard attached to the terminal device to communicate with the combiator on the information center side, which is connected via a telephone line, on the monitor device. Image information is monitored by a device (usually C
(RT display device) as characters and graphics.

Since the information center stores information in various fields in a database, users can shop, make reservations for various facilities, and obtain necessary information without leaving their homes.

[Problem that the invention seeks to solve]

Conventional data terminal devices such as Videotex require many steps to be performed before reaching their original functions of data processing and information retrieval, and these steps are input using a keyboard or the like.

However, as information technology progresses, these terminal devices are increasingly being operated by amateurs rather than by experts, and today, Videotex terminals are one of the devices used for home and public use. It is expected to become popular as a terminal device for information networks, but one of the obstacles to its widespread use is the inconvenience of repeating simple operations unique to terminal devices conversationally through a display device while performing keyboard operations. .

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a data terminal device that can greatly simplify the operation of the terminal device.

[Means for solving problems]

Sometimes, information retrieval can be performed by having the IC card read by an IC card read control section and inputting necessary data into a data input control section such as a keyboard according to an information retrieval program.

[Effect]

The data terminal device according to the present invention has an I
Procedures for searching various types of information required from the center are written in the C card in advance as a program, and when information is acquired, the IC card is read out from the data/evening terminal device. Based on the information search program, predetermined search data is sent to the information center and information search is performed.
