Description

How Internet Fax Processes Fax Data

The present invention relates to a fax data processing method of an Internet fax, and more particularly, the Internet fax operates as an E-mail server without using an Internet service provider (hereinafter, referred to as an 'ISP'). The present invention relates to a fax data processing method of an Internet fax machine that transmits fax data directly through the Internet.

In general, a facsimile is a terminal for data communication such as a document or an image, and is an office automation device in which fax data is transmitted or received using a public telephone network.

In recent years, as facsimile communication is generalized, much information is exchanged through facsimile. Especially for documents that need to be processed quickly, the exchange of information through facsimile is very effective, which greatly improves work efficiency.

In addition, the use of the Internet is increasing in recent years, and the number of users using the Internet facsimile which is much lower than that of the general facsimile is gradually increasing.

As shown in Figure 1, the structure of the Internet fax is transmitted from the Internet fax through a black box to the Public Switched Telephone Network (PSTN) when the ISP transmits the data using a Multipurpose Internet Mail Extensions (MIME) program. Send the fax data to the destination you want. Here, the MIME program is a multipurpose Internet e-mail extension, which extends the Internet e-mail function to transmit multimedia information such as pictures, graphics, audio, and faxes in addition to text (TXT). MIME is defined in Request For Comments (RFC) 1341.

However, according to the conventional Internet fax machine, the following problems occur.

First, to use the Internet facsimile, you have to sign up with an ISP or pay a separate fee to the ISP, causing economic losses.

Secondly, it is inconvenient for the user because it is difficult for the sender to confirm whether or not the fax data is transmitted after transmitting the fax data.

Third, since externally sent fax data is first stored on an e-mail server, users must run a separate application (eg Eudora, etc.) to check the fax data. You have to check it.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to allow the Internet fax to operate as an E-mail server so that fax data can be directly transmitted through the Internet without going through an ISP. It allows users to easily send and confirm fax data at no additional charge. Also, when sending fax data by Internet fax from the outside, the receiving side outputs the fax data as soon as it is received. have.

A feature of the present invention for achieving the above object is to convert the binary data scanned by the scanner into image data to store the changed image data in the common memory; Formatting image data stored in the common memory into an Internet protocol format for transmission to the Internet; The purpose is to transmit the formatted image data to the IP address of the destination that the user wants to transmit over the Internet via TCP / IP.

Here, the method of processing fax data of the Internet fax machine analyzes the image data when the image data is transmitted from the outside through the Internet, stores the image data in the common memory, and converts the image data stored in the common memory into binary data through the printer. Print

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram schematically illustrating an internet fax machine to which the present invention is applied, and FIG. 3 is an operation flowchart for explaining a fax data processing method of an internet fax machine according to the present invention, and FIG. 4 is an internet fax machine according to the present invention. This is a structure diagram showing a structure in which data is transmitted.

Referring to the facsimile part of FIG. 2, the facsimile processing unit 10 generally controls the Internet facsimile according to the set program, and in particular, changes the binary data scanned by the scanner 12 to image data, thereby changing the image. The data is stored in the common memory 11. In addition, the printer 13 converts the image data transmitted through the Internet into binary data.

The common memory 11 stores program data, protocol data, text data, work contents related to transmission and reception, and, in particular, stores image data changed by the central processing unit 11 for facsimile and the Internet. Stores image data transmitted via.

The scanner 12 scans the data of the document, converts the data into digital image data, and provides the same to the facsimile processing unit 10.

The printer 13 prints the received data by the control signal from the central processing unit 10 for the fax.

The modem 14 is modulated and outputs the output data of the facsimile processor 10 in analog form under the control of the facsimile processor 10, and demodulates and outputs the analog input signal.
