First, the control unit 110 determines whether a transmission command received through a transmission button is received in a state dialed to a receiving side facsimile for data transmission (S110). If the transmission command is not received, the control unit 110 maintains the operation of the facsimile in the transmission standby mode (S210).

If it is determined in step S100 that the transmission command has been received, the control unit 110 controls the operation of the scanner 150 so that the scanner 150 picks up and inserts the paper inserted into the paper input port and generates image data (S120). . In this case, the scanner 150 transmits the start information indicating that the first page is the first page for transmission and the page information in which the number of the scanned paper is input to the controller 110. On the other hand, the control unit 110 converts the image data transmitted from the scanner 150 to the text data, and transmits the text data, start information and page information to the public telephone network through the modem 210 and the network control unit 220 ( S130).

After the step S130, the sensor unit 130 determines the presence or absence of paper inserted in the paper insertion hole (S140). If it is determined that there is no paper inserted into the paper insertion hole, the controller 110 transmits the end information indicating the end of the transmission of the text data and the entire transmission information including the page information and the capacity information of the transmitted text data to the public telephone network ( S310).

If it is determined in step S140 that the paper is present in the paper insertion hole, the sensor unit 130 determines whether the paper present is the last paper (S150). If it is determined in step S150 that the last sheet, the scanner 150 picks up and scans the sheet to generate image data (S160). At this time, the scanner 150 transmits the termination information and the page information to inform the end of the transmission to the controller 110. Accordingly, the controller 110 converts the received image data into text data, and transmits the text data, the end information, the page information, and the entire transmission information to the public telephone network through the modem 210 and the network controller 220 ( S170).

On the other hand, if it is determined in step S150 that the paper present in the paper opening is not the last paper, the scanner 150 picks up and scans the paper to generate image data, and transmits the page information to the control unit 110 (S410) . Accordingly, the controller 110 converts the received image data into text data, transmits the text data and page information to the public telephone network through the modem 210 and the network controller 220, and performs step S150 (S420). ).

Therefore, the receiving side of the facsimile can confirm the error of the received character data caused by the interference on the transmission channel of the transmitted character data and the error of the exchange.

In the present embodiment, the facsimile has been described as an example, but it may be applied to a multifunction device having the facsimile function of the present embodiment.

According to the present invention, when the transmitting side fax transmits the text data for the first time to the receiver, information indicating that it is the first page is transmitted to the receiving side. By transmitting, the receiving side facsimile can grasp the total capacity of the transmitted character data through the entire information of the data transmitted from the transmitting side, and can confirm the character data lost on the transmission.

In addition, in the receiving side facsimile, it is possible to determine whether there is a reception error in the character data received through the time information, the page information transmitted for each page, and the entire transmission information, thereby increasing the reception accuracy of the text data.

In the above described and illustrated with respect to the preferred embodiment of the present invention, the present invention is not limited to the specific preferred embodiment described above, without departing from the gist of the invention claimed in the claims in the art Various modifications can be made by those skilled in the art, and such changes are within the scope of the claims.
