Description

Fax machine and its transmission method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus and a transmission method thereof. In particular, a facsimile apparatus and a transmission thereof having a function of prohibiting transmission when there is an error in a reception facsimile apparatus when a facsimile information is to be transmitted from a transmission facsimile apparatus to a reception facsimile apparatus. It is about a method.

1 is a block diagram showing the configuration of a facsimile system according to the prior art.

Referring to FIG. 1, an operation unit 10 for a user to directly input an operation control signal or transmission data of a system, a recording unit 20 for outputting data received from the outside, and a program required for operation of the system are stored. A ROM (ROM: 30), a RAM for storing data for transmission or reception of a system (RAM: 40), a modem (MODEM: 50) for performing modulation or demodulation of data for transmission or reception of a system; And a network control unit 60 connected between the modem 50 and an external telephone line to perform data transmission or reception, and a microcomputer 70 connected to each part to control the overall operation of the system. .

In a typical facsimile transmission / reception system, transmission and reception of picture information is performed between two facsimile apparatuses having the configuration of FIG. 1, a facsimile to transmit data is called a transmit facsimile, As illustrated in FIG. 2, the document data is processed into document information data in a transmission facsimile and transmitted to the reception facsimile according to a predetermined sequence.

At this time, the transmission and reception operation is a process of connecting a line between two terminals (phase A), a process of checking the function and status of the terminal and the transmission path and controlling the terminal (phase B), a process of transmitting a message (phase C), a message It consists of checking the reception status of (phase D), cutting the line (phase E).

Phase A transmits a dial and non-voice terminal equipment indication signal (CNG) from a transmitting fax to a receiving fax, and sends a non-voice terminal equipment acknowledgment signal (CED) from the receiving fax to the transmitting fax. The process of connecting.

In addition, the phase B transmits a digital identification signal (DIS) from the receiving facsimile to the transmitting facsimile and informs the transmitting facsimile of the function of the receiving facsimile, the digital command signal from the sending facsimile to the receiving facsimile. Send DCS) to indicate the selected function in the sending fax. Subsequently, a modem training check (TCF) is sent to transmit the message from the sending fax to the receiving fax, indicating that the message may be sent by sending a confirmation to receive (CFR) message from the receiving fax to the sending fax. This is the process of telling.

In addition, the phase C is a process of changing a transmission document into speech information and transmitting from a transmission facsimile to a reception facsimile.

In addition, the phase D is a process of sending an end of procedure (EOP) when the transmission of the talk information from the transmission facsimile to the reception facsimile to notify that the transmission of the message is completed. In this case, the receiving fax may transmit a message confirmation signal (MCF) to inform that the message has been completely received.

In addition, phase E is a process of disconnecting a circuit by sending a disconnection signal (disconnect: DCN) from a transmitting facsimile to a receiving facsimile.

On the other hand, an abnormality may occur in the receiving facsimile during the above operation. For example, when the recording paper is exhausted, when the memory for storing the received data is insufficient, when the cover of the facsimile is open, the recording device may fail. Cases, etc. In addition, obstacles in the recording apparatus include a lack of toner or ink, overheating of TPH (Thermal Print Head), and the like.

As described above, when an error occurs in the reception fax, regardless of the reception mode, when a dial is received from the other party's transmission fax, the phone is unconditionally switched to the telephone mode and the line is connected only when the user answers the call.

In the prior art, when an abnormal phenomenon occurs during receiving call information, in the case of FIG. 2, the receiving apparatus cuts a line in phase C to alert the user of the abnormal phenomenon, and the transmitting apparatus transmits all the calling information and then ends the procedure signal (EOP). Even if you send a message, you will not receive the message acknowledgment signal (MCF) from the receiving fax machine.

In the case of FIG. 3, the reception facsimile maintains its state when an abnormality occurs and receives a procedure interrupt negative (PIN) after receiving the procedure end signal (EOP) of the transmission facsimile. Notifies you that you did not receive correctly and that you can no longer receive it without user intervention. At this time, the sending facsimile generates a user call signal and, when the user responds to the call, sends a PRI-Q signal to the receiving facsimile and calls the users of the receiving facsimile to make a phone call with each other to determine the current abnormal state and handle the abnormal phenomenon. If the call fails to respond, the error handling operation is performed.

In the conventional facsimile transmission / reception system as described above, when an error occurs in the receiving part of the receiving facsimile, the sending facsimile does not know the exact reason why the receiving facsimile cannot receive. A problem arises in that it wastes time and money until the user of the receiving fax machine answers by occupying the telephone line every time it sends.

In addition, the automatic transmission of one-touch dials, speed dials, redials, and the like continues to be processed as an error, resulting in a waste of recording paper because communication results are recorded in the communication management report.

The present invention has been made to solve the above problems, the object of which is to store the number of the receiving facsimile of the abnormality to prohibit the transmission when the transmission command is input to increase the prohibition of occupation of the telephone line and improve the work efficiency. To provide a facsimile apparatus and a transmission method thereof.

In the above, the user may directly input the unique number of the receiving fax machine that the error phenomenon occurs directly through the operation unit 110.

The operation of the present invention configured as described above will be described in detail with reference to the flowchart of FIG. 5.

First, when the system is on, the microcomputer 190 performs an operation according to a program stored in the ROM 130. At this time, when an error occurs during the transmission and reception of the document and the user recognizes the situation as a telephone call, the user may directly input the reception abnormal fax unique number through the operation unit 110. At this time, the microcomputer 190 determines whether the reception abnormal fax unique number is input through the operation unit 110 (S201), and if the result is "Yes", the microcomputer 190 stores the input fax unique number in the memory area. )

Thereafter, it is determined whether or not a transmission command of the original is input by the user (S203). If the result is "Yes", the unique number of the facsimile system to be transmitted is compared with the unique number of the error state facsimile system input and stored in S201. (S204), it is determined whether the facsimile unique number matches (S205).

At this time, if the result of S205 is "No", that is, if the unique numbers do not match, the document is transmitted (S206). If the result of S205 is "Yes", that is, if the unique numbers match, the error state is a facsimile system. The alarm generates a warning sound and displays the same on a display window (S207).

On the other hand, if the result in step S203 is "No", that is, it is determined whether a telephone ring is received if a transmission command of the original is not input. (S208) At this time, if the telephone ring is not received, the operation of the system is terminated and the telephone ring is received. In operation S209, the error signal identification unit 180 is operated to determine whether an error status signal of another fax system is received.

If the determination result of S209 is "No", that is, if an error state signal is not received, the document is received (S210), and the recording unit 120 is operated to output data of the original received from the outside. In addition, if the determination result of S209 is "Yes", that is, when an error state signal is received, the unique number of the facsimile system is stored.

In the reception facsimile, when an error occurs during reception, an error status signal is generated through the error signal generator 170 to inform the transmission facsimile that an error occurs in the reception part of the system so that the reception operation cannot be performed. As shown in FIG. 6, a dial signal is transmitted to a unique number of a transmission fax received in phase B, and when a line is connected, an abnormality signal indicating that reception of call information is not made correctly is transmitted within 1.8 seconds, Send line disconnect signal DCN to end.

In the above operation, when the reception abnormality is returned and a signal indicating that reception is possible is received from the reception fax, the stored unique number is deleted to enable transmission.

As described above, the facsimile apparatus and its transmission method according to the present invention manage a unique number of a facsimile system that cannot perform a reception operation due to an error in the reception unit. By making it easy to inform, it is possible to shorten the time occupying the telephone line, thereby improving work efficiency and reducing the burden of communication costs.

In addition, since output of various reports due to transmission errors can be reduced, waste of recording paper can be prevented.
