Abstract

The present invention relates to a text communication method that converts a document created on a computer into image data performed by a facsimile and transmits and receives a document of a counterpart. Since the data of a document created on a computer is character code data, it is necessary to convert it to image data on a facsimile and transmit it to the other party's facsimile. According to such image data, the transmission speed and the transmission quality at the time of printing are reduced. To this end, character code data is adopted in place of image data, which is a transmission / reception data of a computer-facsimile. In addition, a document created on a computer is transmitted to the other party's facsimile through a computer-facsimile text communication method that designates a code indicating that text communication is possible for an NSF / NSS signal that the manufacturer can arbitrarily specify in a facsimile protocol. In the computer-facsimile character communication method described above, a character code data corresponding to a document created on a computer is transmitted with a code indicating that character communication is possible with an NSF / NSS signal on a protocol and an NSF / NSS signal on a protocol. The character-communication method is implemented in the computer-facsimile by specifying a code indicating that the character communication is possible and transmitting the character code data corresponding to the document created on the computer to the message area of the protocol. As a result, the character code table of the character recognition function is added to the existing general facsimile, so it can also function as a conventional facsimile and a character output device.In the case of the character output function, the character code data is transmitted and the received character code data is transferred. Because it prints immediately, it enables ultra-fast transmission and high quality printing, which reduces transmission time by 1/10. It also reduces errors caused by the conversion of facsimile data from computer-fax or DCP. Therefore, the highest transmission speed and high quality printing are possible in terms of documents created by an office automation machine rather than a manuscript.

Transmitting a signal indicating that communication is possible to the transmitting side, receiving and decoding a signal indicating that text communication is possible from the facsimile of the transmitting side; And transmitting the document created from the computer to the fax on the receiving side. The text communication method according to claim 1, wherein a speed at which a document created from a computer is transmitted to a fax on the receiving side is 300 BPS. The system of claim 1, wherein the signal indicating that text communication is possible is 5 bytes indicating a reference of a facsimile manufacturer, 1 byte indicating a code indicating that text communication is possible, 1 byte indicating an information amount of character code data to be transmitted, and A character communication method, characterized by comprising: a signal for carrying information subsequent to a byte representing an information amount of character code data. In a character communication method performed by a computer-fax machine transmission / reception protocol, a step of causing a sending-side facsimile to generate a call signal indicating that the receiving-facsimile has started receiving, and that the receiving-facsimile is a text message. Transmitting a signal indicating that communication is possible to the transmitting side, receiving and decoding a signal indicating that text communication is possible from the receiving side facsimile, and transmitting a text transmission capable signal to the receiving side facsimile; Transmitting character code data from the sending side facsimile to the receiving side facsimile to test whether the receiving side facsimile can be properly received before transmitting the character code data for the receiving side facsimile; The receiving side facsimile to the sending side facsimile From the computer in response to the sending facsimile that the character code test data has been properly received and from the receiving side facsimile that the character code test data from the sending facsimile has been properly received. And transmitting the character code data corresponding to the created document to the receiving side facsimile, thereby transmitting the document created from the computer to the receiving side facsimile. The text communication method according to claim 4, wherein a speed of transmitting a document created from a computer to a fax on the receiving side is 9600 BPS. 5. The text communication method according to claim 4, wherein the signal that the text communication is possible is a signal composed of 5 bytes indicating a reference of each manufacturer of the facsimile and 1 byte indicating a code indicating that text communication is possible. The text communication method according to claim 3 or 6, wherein a code indicating that text communication is possible is 77. ※ Note: The disclosure is based on the initial application.
