(Problems to be Solved by the Invention) However, the conventional communication terminal device has the following problems.

As described in the above-mentioned literature, the transmission of conventional facsimile functions is controlled by a procedure intended only for the purpose of transmitting documents and images. Therefore, when searching for seals and signatures in the database by facsimile via telephone line or wireless communication, or conversely registering such data into the database by facsimile, it is necessary to have a voice communication between operators or There is a need for identification of items in the database between the operator and the speech recognition device. Therefore, long-time communication is required, and the operator is likely to misidentify the system, resulting in a decrease in reliability.

Furthermore, when transmitting image data by facsimile after specifying items in a database using a data input/output terminal device as explained in FIG. However, it had drawbacks such as poor operability and requiring long communication times.

The present invention solves the problems of the prior art and provides a communication terminal device that integrates data communication such as single character numbers and image data communication, and enables easy-to-operate and highly reliable communication. It is.

(Means for Solving the Problems) The present invention includes an encoding section that encodes input image data, and a decoding section that reproduces the encoded image data into original image data and outputs it. , a facsimile unit including a communication control unit that connects the encoding unit and the decoding unit to a communication line; an input unit that inputs character data; a display unit that displays data on a display screen; a data processing section that performs de-processing to enable data communication with the database based on the output signal of the section and displays the contents on the display section; and a data processing section that connects the data processing section to a communication line. and a character data input/output terminal section consisting of a communication control section and a character data input/output terminal section, and means for connecting each communication F#i control section of the facsimile section and the character data input/output terminal section, each communication control section: When a connection is detected, the mode is set to search and register image data in the database, and one of the communication control units notifies the database of the start of communication through the communication line, and the character data input/output terminal unit When the communication control section of the facsimile section controls the data processing section to enable specifying the item in the database, and the input section is used to specify the item, the communication control section of the facsimile section controls the data processing section to specify the item in the database. This is a communication terminal device characterized in that the receiver is in a state for handing over, and searches and registers image data in a database.

(Operation) According to the present invention, since the communication terminal device is configured as described above, the technical means operates as follows.

When the communication control sections of the facsimile section and the character data input/output terminal section are not connected, the facsimile section and the character data input/output terminal section operate independently. When each communication control unit is connected, each communication control unit detects the connection, enters a mode for searching and registering image data in the database, and connects the facsimile unit and character data input/output terminal unit respectively.
