Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a facsimile apparatus capable of suitably preventing omission of reception of a received message when a recording paper jam occurs in a recording unit.

[Technical background of the invention and its problems]

In a conventional facsimile machine, the presence or absence of normal recording paper is normally detected, and if a recording paper break is detected during the reception of a telegram, immediately stop all receiving operations, and then prompt the operator to inform that the recording paper is exhausted. I was trying to inform you. Therefore, in this case, in order to receive all the electronic messages on the receiving side, the operator on the receiving side had to fill the new recording sheet, contact the receiving side, and have the transmitting side send the same electronic message again.

In addition, even in a facsimile machine that has a memory storage function for received messages, if a paper jam is detected during reception,
Similarly to the above, regarding the communication of this time, all the receiving operations are immediately stopped, and if the operator does not supplement the recording paper, the next receiving operation is switched to the memory receiving. Therefore, also in this case, the operator on the receiving side needs to perform the same troublesome procedure as described above and have the transmitting side retransmit the same electronic message in order to obtain all the electronic messages.

[Object of the Invention]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned drawbacks, to reliably prevent reception failure when a recording paper jam occurs, and to provide a facsimile apparatus which does not require a retransmission operation from the transmitting side.

[Outline of Invention]

According to the present invention, in a facsimile apparatus having a recording unit for recording a received electronic message and a memory for accumulating and storing the received electronic message, the remaining amount of recording paper is detected, and the remaining amount is at least 1 page during receiving recording in the recording unit. At the end of the page, after the reception and recording of the page is finished, the received telegrams of the next page and subsequent pages are output to the memory, and the received telegrams of the next page and subsequent pages are accumulated and stored in the memory.

Example of Invention

FIG. 1 conceptually shows an embodiment of the present invention, in which 1 is a network control / modulation / demodulation unit for performing line connection control and modulation / demodulation operations, 2 is a transmission control unit for decoding control information, 3
Is a switching circuit for outputting the image information VD input from the transmission control unit 2 to either the decoding unit 4 or the memory 6, 4 is a decoding unit for decoding encoded image information, and 5 is an image on recording paper. A recording unit for recording information, 6 a memory for accumulating and storing image information, 7 a remaining amount detecting unit for detecting the remaining amount of recording paper, 8 a system for controlling the entire system and switching control of the switching circuit 3. It is a control unit. There are various possible configurations for detecting the remaining amount of recording paper. For example, a roll of recording paper has a predetermined length (for example, 1 m
A method in which a black band (end mark) is printed in advance and the end mark is detected by an optical element can be used. In the configuration shown in FIG. 1, only the receiving unit is shown and the transmitting unit is not shown.

Hereinafter, an operation example of the above configuration will be described according to the flowchart shown in FIG.

When the reception operation is started, the message VD from the transmission side is input to the network control / modulation / demodulation unit 1 and demodulated by the modulation / demodulation unit.
The control information is input to the transmission control unit 2 and decoded. Here, the remaining amount detection unit 7 constantly detects the remaining amount of the recording paper by detecting the end mark described above, and when the end mark is detected and it is detected that the recording paper is below a predetermined amount, The detection signal is input to the system controller 8. The system controller 8 controls switching of the contacts of the switching circuit 3 based on the presence / absence of the detection signal input (step 10). That is,
When the detection signal is not input, the system control unit 8 connects the contact of the switching circuit 3 to the decoding unit 4 side, and when the detection signal is input, if it is in the middle of receiving, the next page of the page From the reception, the contact of the switching circuit 3 is switched and connected to the memory 6 side.

Therefore, when it is determined that the remaining amount of recording paper is equal to or larger than the predetermined amount, the electronic message output from the transmission control unit 2 is input to the decoding unit 4 via the switching circuit 3 and is decoded by the decoding unit 4. After being converted into raster information for each scanning line, it is input to the recording unit 5 and recorded on recording paper (step 20). In this way, when the recording operation of the telegram for one page is completed (step 30), it is then searched whether or not the received telegram for one page is the final page (step 4).
0), if it is the last page, stop the receiving operation. If there is a telegram on the next page or later, the network control / modulation / demodulation unit 1 described above is used unless the remaining amount of recording paper falls below a predetermined amount.
A normal reception operation for transmitting data to the transmission control unit 2, the switching circuit 3, the decoding unit 4, and the recording unit 5 is executed.

However, if the end mark on the back surface of the recording paper is detected by the remaining amount detection unit 7 while the above receiving operation is repeated and a detection signal is input to the system control unit 8, the system control unit 8 causes the switching circuit 3 to operate. The contact of is switched to the memory 6 side (step 50). At this time, since the actual contact switching of the switching circuit 3 is performed at the boundary of each page, even if the end mark is detected in the middle of a certain page,
The electronic message of the page is input to the printing unit 5 to the end, and is recorded and output as a complete one-page electronic message with no information missing. On the other hand, the messages from the next page onward are input to the memory 6 by the switching circuit 3, and are stored and stored in the memory 6 until the last page. When the storage process up to the final page is completed (step 60), the system control unit 7 informs the operator of the recording paper jam in the recording unit 4 by displaying, for example, a defective code and turns on an appropriate lamp. Then, after performing predetermined post-processing such as notifying the operator that the remaining information is stored in the memory 6 (step 70), the apparatus is stopped.

After that, the operator on the receiving side fills a new recording sheet, and then transfers the stored content of the memory 6 to the recording section 5 via the decoding section 4 by an appropriate operation, so that the recording output is caused by a paper jam. It is possible to record and output the remaining information on the recording paper, which has not been printed, on the subsequent pages.

〔The invention's effect〕

As described above, according to the present invention, it is necessary to reliably prevent the reception message from being missed when a recording paper jam occurs, and thus to make it difficult for the transmitting side to retransmit the same message. Can be eliminated, and office efficiency can be improved.
