For example, there is a facsimile apparatus that automatically and appropriately responds to an erroneous connection with a different communication partner. For example, as described in Japanese Patent Application Laid-Open No. 58-170171, when a wrong connection is confirmed by providing a means for detecting a wrong connection and a voice generating device in a facsimile apparatus that performs automatic dial transmission or the like. , Send the apology. That is, when the CED (Called Terminal Identification) signal is not received from the partner connected by the telephone line network or the like, it can be determined that the connected partner is not the facsimile machine. Therefore, in such a case, an apology or the like by voice is notified.

Further, in Japanese Unexamined Patent Publication No. 2-105665, when a CED signal is not detected after a call is made, an erroneous dial message is sent to notify the other party of the erroneous dialing by a facsimile machine. There is also a device. On the other hand, in the case where the CED signal is received and it is confirmed that the connection destination is a facsimile machine, there is also one that confirms the destination before starting the transmission of the transmission data (Actual Kaihei 4-71062). Issue).

[0004]

However, the facsimile machine for these erroneous connections can only deal with calling the wrong destination number and connecting the line.
In other words, in the conventional facsimile machine, when the transmission destination is wrong after the line is connected and data transmission is started, appropriate response is made to the already transmitted contents. I couldn't. Therefore, it is an object of the present invention to provide a facsimile apparatus capable of appropriately responding even after data has already been transmitted.

[0005]

According to a first aspect of the present invention, in a facsimile apparatus for transmitting and receiving image information,
Interruption input means for inputting an instruction to interrupt transmission during transmission,
In order to achieve the above-mentioned object, the facsimile device is provided with a transmitting means for transmitting clear information for instructing the clearing of the information already transmitted and printed on the recording paper when the transmission interruption is instructed by the interruption inputting means. . According to the invention described in claim 2, in the facsimile apparatus for transmitting and receiving image information,
A facsimile apparatus is provided with a reception monitoring unit that monitors reception of clear information during communication and a clear unit that clears information already received and printed on recording paper when the reception monitoring unit receives clear information. To achieve the above-mentioned object. According to a third aspect of the present invention, the facsimile apparatus according to the first aspect further comprises comment transmitting means for clearing additional information such as TTI and transmitting a comment regarding transmission interruption. According to a fourth aspect of the present invention, the facsimile apparatus according to the second aspect further comprises a means for clearing the additional information and a printing means for printing the comment received by the receiving means on the recording paper cleared by the clearing means. .

[0006]

According to the present invention, when an error in the transmission destination or an error in the transmission content is noticed during the transmission of the image information, the transmission is interrupted by a predetermined operation and the clear information is transmitted from the transmission means. It instructs the facsimile machine on the receiving side to clear the data transmitted before that. On the other hand, when receiving the clear information, the facsimile machine on the receiving side clears the information already received and printed on the recording paper. Further, the transmission interruption is printed on the recording paper so as not to inconvenience the other party in the case of the erroneous transmission.

Are arranged. Although the writing system in the facsimile apparatus of this embodiment is constructed in this way, the other parts such as the reading system are constructed by the same mechanism as the conventional facsimile apparatus.

Next, the operation of the embodiment thus constructed will be described. First, the normal printing operation when receiving a facsimile will be described. The recording paper 22 held by the roll receiver 21 is pressed against the thermal head 23 by the pressure spring 9, and printing is performed. When printing by the thermal head 23 is completed, the recording paper 22
Is fed to the position of the cutter 26 by the platen 7. Further, the recording paper 22 is ejected according to the recording paper bus by the paper ejection guide 28 and the paper ejection roller 30. When the end position of one page passes the platen 7, the cutter 26 is driven by the cutter motor 27, and the recording paper 22 is cut page by page.

Next, the operation of the present invention will be described. Figure 3
Represents a communication protocol related to erroneous communication stop processing. When the image information 51 is transmitted from the transmitting side to the receiving side facsimile apparatus, the receiving side facsimile apparatus performs the printing process as usual by the above-described normal printing operation. If the operator who is performing facsimile transmission notices an error in the original document or an error in the other party during the transmission of the image information 51, he or she presses the erroneous communication stop processing key of the input device 18. As a result, in the transmission side facsimile apparatus, the communication control unit 16 sends the flag (FLG) 52 indicating the stop of transmission due to erroneous communication, and the interruption comment 53 due to interruption of transmission. Examples of this interrupted comment include various comments such as "I made a mistake in the number. Sorry" and "I made a mistake in the sent contents. Sorry."

As the interruption comment 53, a code corresponding to each character string of the comment contents is stored in advance in the ROM 13 or the RAM 14 of both the facsimile machines on the transmitting side and the receiving side. Then, the transmitting side facsimile device transmits the code of the character string corresponding to the comment number designated by the operator to the receiving side facsimile device. Upon receiving the FLG 52, the facsimile machine on the receiving side recognizes that the information to be subsequently transmitted is the interruption comment 53.

When the interruption comment 53 is transmitted, the interruption processing described below is performed between the two facsimile machines. That is, in the transmitting side facsimile apparatus, the procedure end signal (EO) indicating that there is no other transmitted document is sent.
P) 54 is transmitted. In the receiving facsimile machine, E
The acknowledgment to OP 54 sends a message confirmation signal (MCF) 55 indicating that the message has been completely received. Further, when the EPO 54 is received, the process proceeds to Phase E, which is the process of call restoration, that is, the line disconnection. The sending facsimile machine indicates the start of phase E and sends a disconnection command signal (DCN) that does not require a response.

FIG. 4 shows the operation of the erroneous communication stop processing at the time of receiving the facsimile data, and FIG. 5 shows each state of the receiving side facsimile apparatus in this erroneous communication stop processing operation. In the facsimile apparatus in the standby state for receiving the image information 51, as shown in FIG. 5A, the thermal head 2 where the leading end of the recording paper 22 is the print start position.
It is on the discharge direction side (the left side in the drawing) by the amount of the margin of the tip, compared with 3. When communication is started in this state, the receiving facsimile machine prints the image information 51 received from the communication control unit 15 (step 11 in FIG. 4). That is, as shown in FIG. 5B, at the same time when printing is started, the recording paper 2 is ejected by the paper ejection roller 30, the platen 25, and the recording paper roller 33.
2 is fed to the discharge direction side, and the above-described normal printing operation is performed.

The CPU 11 monitors whether or not the FLG 52 is received by the communication controller 15 during the normal printing operation (step 12). When the FLG 52 is received (step 12; Y), the interrupt comment 53 transmitted subsequently is received and stored in a predetermined area of the RAM 14 (step 13). Next, the CPU of the receiving side facsimile machine
11 is an interruption process (EOP, MCF, D) with the transmission side.
(CN transmission / reception), printing of the image information 51 is stopped, and the stop position is stored in a predetermined area of the RAM 14 (step 15). Then, as shown in FIG. 5C, the recording paper 22 is rewound in the reverse direction by the recording paper roller 33 (step 16).

The CPU 11 rewinds the recording paper 2
It is monitored whether or not the leading edge of No. 2 has returned, and when the leading edge has returned (step 17; Y), rewinding of the recording paper 22, that is, conveyance in the reverse direction is stopped (step 18). Then, as shown in FIG. 5D, the facsimile machine feeds the rewound recording paper 22 again in the paper ejection direction by the paper ejection roller 30, the platen 25, and the recording paper roller 33.
Black data is printed by the thermal head 23 (step 1
9). This black solid printing is performed by RA in step 15.
The process is performed up to the print stop position stored in M14 (step 20). This prevents the recipient from seeing the printed image information that has already been erroneously transmitted and has been recorded. Thereafter, as shown in FIG. 5E, the receiving facsimile machine prints the transmission interruption comment 53 received in step 13 and stored in the predetermined area of the RAM 14 (step 2).
1), the process ends.

In the embodiment described above, the sending side facsimile apparatus is configured to send the code of the character string corresponding to the comment number designated by the operator as the interrupted comment 53, but the present invention is not limited to this. However, other modifications are possible. For example, ROM 13 or RAM on the receiving side
The interruption comment 53 is stored in 14, and only the comment number is transmitted on the transmitting side, and the comment content corresponding to the received comment number is transmitted on the receiving side to the ROM 13 or RA.
It may be read from M14 and recorded. The interruption comment 53 is image information indicating various comments, which is read in advance from a scanner or the like and read by the sender R.
The image information corresponding to the comment number specified by the operator may be stored in the AM 14 and transmitted to the receiving side facsimile apparatus. Furthermore, in the embodiment, the interruption comment is printed, but the interruption comment may be output by voice. In this case, the transmitting side facsimile device transmits a code corresponding to the comment content by voice.

[0020]

According to the facsimile apparatus of the first aspect, it is possible to notify the receiver side of the interruption of transmission.
Therefore, in the receiving side facsimile apparatus, it is possible to distinguish between normal communication termination and abnormal termination. According to the second aspect of the present invention, the information already received and printed on the recording paper can be cleared. The transmission information is kept secret to the sender, and the recipient does not have to receive the confusing document. According to the facsimile apparatus of the third aspect, the fact that the transmission is interrupted can be printed as a comment on the received document, so that the recipient can be prevented from inconvenience. According to the facsimile apparatus of the fourth aspect, it is possible to print the comment of the transmission interruption.
