The display device 18 is a liquid crystal display device or the like, and is a device for displaying various information such as the telephone number of the other party, the current time, and an alarm at the time of failure.

Next, the operation of the facsimile communication apparatus having the above configuration will be described. FIG. 7 shows an operation flowchart of the facsimile communication apparatus at the time of transmission. First, when the user inserts the medium into the facsimile communication device, the medium is read by the medium reading device 10 and stored in the medium data storage unit 121 of the information storage device 12 (step S11). Further, the user inputs dial information such as the facsimile telephone number of the other party and various information from the input keyboard device 13, and these data are stored in the data storage unit 122 for various functions of the information storage device 12 ( Step S1
2).

Next, the facsimile communication apparatus secures a communication line with the facsimile communication apparatus which is a communication partner (step S13). That is, the storage management device 11
The destination dial information stored in the data storage unit 122 for various functions is read and transmitted to the line management device 15, and the line management device 15 performs line establishment processing. Further, when the line cannot be established immediately because the other party is busy, the line management device 15 performs a line establishment process again after a certain time as a so-called redial function to secure the line. This line is repeated until it is possible. When the communication line is secured, the facsimile communication device performs a transmission process (step S14). That is, the medium information converted into the electric signal and stored in the medium data storage unit 121 is
It is sequentially read by the storage management device 11. Then, the encoding / decoding device 14 converts the signal into a signal of the format defined by the communication standard of the facsimile communication device, and the signal is sent from the line terminating device 16 onto the communication line. This process is repeated until the end of the medium data stored in the medium data storage unit 121.

FIG. 8 is a flow chart showing the above-mentioned transmission processing in detail. First, the storage management device 11 extracts the information corresponding to one transmission process from the medium information stored in the medium data storage unit 121 (step S141).
Next, the encoding / decoding device 14 uses the medium data storage unit 12
The information extracted from 1 is encoded into a signal of a format defined by the communication standard of the facsimile communication device and sent to the line management device 15 (step S142). Then, the line management device 15 sends the encoded medium signal to the communication line via the line terminating device 16 (step S1).
43). Further, the storage management device 11 determines whether or not all the medium information accumulated in the medium data accumulating unit 121 has been subjected to the transmission processing (step S144), and if there is no transmission data, the transmission processing is ended and transmission is performed. If the information to be processed remains, the process returns to step S141 to continue the transmission process.

FIG. 9 shows a document transmitted by such a transmission process. That is, this document shows the document on the receiving side, and the reception time, the telephone number (facsimile number) of the transmission destination, and the number of pages are described as the header together with the body of the document.

[0010]

However, in the facsimile communication apparatus, the data on the medium may not be completely transmitted due to an abnormality in the communication line during transmission, and the operation may be interrupted midway. In such a case, when the line abnormality is recovered and the document is transmitted again, the receiving side has a problem that it is not known which document this is, and which document is the continuation. In particular, in a facsimile communication device that continuously receives from various destinations, a line failure occurs while a certain document is being sent,
When the data from the sending side is interrupted, another document may be sent from another sending destination. In such a case, even if the fault is recovered and the document is sent again, the document is mixed with the document from another transmission source, which makes it difficult to identify the document.

Conventionally, information such as time, telephone number, and number of pages is displayed in the received document as shown in FIG. 9, but the time information is used to identify the retransmitted document such as a failure. It is useless, and although it is possible to identify which sender is the phone number information, it is difficult to identify the document when multiple documents are sent from the same sender. Met. Further, in the page number information, it is possible to identify the document to some extent by referring to the telephone number information, but it is a very troublesome task to identify the document when the document is received from various senders. Was needed.

For example, a normal facsimile communication apparatus operates in an unmanned state on holidays, at night, and the like. When many documents are received from multiple senders in such a state, those documents are simply printed and accumulated on the reception paper, and therefore the user can copy these documents after a holiday or the next time. It has to be sorted by day, and this kind of work is very troublesome if only the information such as the telephone number and the number of pages is described as in the past. The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a facsimile communication apparatus capable of easily specifying which document is received even when a plurality of documents are received. And

In addition, the synchronization device 30 includes the line monitoring means 25.
2 and the transmission data management means 29 have a function of managing the synchronization processing.

Next, the operation of the facsimile communication device will be described. FIG. 2 shows a flowchart of the operation. First, the medium is read by the medium reading device 20,
The read data is stored in the medium data storage unit 221 of the information storage device 22 by the storage management device 21 (step S1). Next, the user inputs dial information of the other party from the input keyboard device 23, and this data is stored in the data storage unit 222 for various functions (step S2). Then, the line connection control means 251 of the line management device 25 secures a communication line with the destination facsimile communication device based on the dial information or the like accumulated in the data storage unit 222 for various functions (step S3). Also,
Here, if the line cannot be established immediately because the other party is talking, redial operation is performed. Once the communication line is secured,
The medium data converted into an electric signal and stored in the medium data storage unit 221 are sequentially read by the storage management device 21, coded by the coding / decoding device 24, and sent out from the line terminating device 26 onto the communication line. (Step S
4).

Further, the line monitoring means 252 is monitoring the state of the communication line, and the monitoring device 252 monitors the state of this monitoring.
The data is successively reported to the transmission data management means 29 by 0.
That is, the transmission data management means 29 is the line monitoring means 252.
The output signal of 1 counts up the number of transmitted pages one by one, and the current number of transmitted pages is constantly managed. On the other hand, after the communication line is established, if a communication error occurs due to a line error or the like, the facsimile communication device performs a failure process (step S5).

FIG. 3 is a flow chart showing details of the transmission process of step S4 in FIG. First, the storage management device 21 determines whether or not the transmission data is retransmission data (step S41). If the transmission data is not retransmission data, the document identification information management means 211 allocates document identification information (document identification ID). The document identification information is stored in the document identification information storage unit 223 (step S42). The document identification information is, for example, "001" to "99".
The identification information is composed of a three-digit number such as "9" and is counted up for each document, and "999" returns to the original.

Next, the document identification information management means 211
The stored document identification information is retrieved (step S44). In addition, in step S41, if the transmission data is retransmission data, a retransmission slip generation process is performed (step S43), and the document identification information extraction process of step S44 is performed. Will be described later. After that, the storage management device 21 uses the data storage unit 22 for various functions.
The time is retrieved from the telephone number stored in No. 2 or a clock mechanism (not shown) (step S45), and the medium data is retrieved from the medium data storage unit 221 (step S4).
6). Then, the medium data extracted in step S46 is encoded by the encoding / decoding device 24 (step S47), and the encoded data is sent to the communication line via the line terminating device 26 (step S48). .

After that, the line monitoring means 252 monitors the line status and determines whether or not a communication failure has occurred (step S49). Here, when the communication failure does not occur and it is in the normal transmission state, the line monitoring means 252 sends a signal indicating normal transmission to the transmission data management means 29, and the transmission data management means 29 causes the normal transmission page. The number is updated (counted up) (step S410). Then, the storage management device 21 checks whether or not all the medium data stored in the medium data storage unit 221 has been transmitted (step S41).
1) If the transmission is completed, the transmission process is ended, and if there is data to be transmitted, the process returns to step S41 and the transmission process is repeated.

FIG. 4 shows a document received by the facsimile communication device on the other side, and (a) shows a document that has been normally transmitted.
(B) shows a retransmitted document. As shown in (a) of FIG.
For the document on the receiving side, the document identification information management means 211 displays the ID of the document in the header together with the time, telephone number, and page number. This ID is assigned in step S42 above,
It is transmitted to the receiving side according to the document identification information extracted at 44. On the other hand, if it is determined in step S49 that a communication failure has occurred due to, for example, the line being disconnected or the receiving side being unable to receive, the failure processing shown in step S5 of FIG. 2 is performed.

FIG. 5 shows a flowchart of the fault processing. That is, when the line monitoring means 252 detects the occurrence of a failure, the transmission data detecting means 211 calculates the number of normally transmitted pages, and the line monitoring means 252 checks whether or not this failure is a line abnormality ( Step S5
1). That is, it is confirmed whether the line is cut off for some reason, or the line is in the connected state but the transmission is disabled due to a failure of the partner device. Here, if the line is normal, the receiving device waits for a receivable signal from the partner device (step S52), and when the partner device becomes receivable, the transmission control means 214 causes the transmission data detecting means 2 to operate.
The retransmission position of the untransmitted data after the normal transmission page detected by 12 is set (step S54), the retransmission flag is set (step S55), and the process returns to the transmission process.

If the failure is a line abnormality, the dial information stored in the data storage unit 222 for various functions is transmitted to the line management device 25, as in the communication line establishing process in step S3. Line connection control means 25
1 establishes the line again (step S53), and then shifts to the retransmission position setting process of step S54.

When the failure process is performed and the process returns to step S41 of the transmission process shown in FIG. 3, since the retransmission data is the retransmission data in this retransmission determination, the process proceeds to step S42 and the retransmission slip generation process is performed. That is, this retransmission slip generation process is performed by the retransmission identification information management means 213.
The format of the resend slip is read from and is added to the header part together with the data of the resent document. After that, the same processing as the above from step S44 is performed, and when all the transmission data are normally transmitted, the transmission processing ends.
The document received by performing such resend processing is the document shown in FIG. That is, the retransmitted information indicating the retransmitted document is displayed together with the ID at the time of normal transmission, and the retransmitted identification information management means 2
It is done by 13. In addition, this resend display operation is
Similar to the above-mentioned retransmission form generation processing, the retransmission identification information management means 213 reads out the format of the retransmission form from the retransmission form information storage section 224.

In the above embodiment, the document identification information is added to the transmitted document and the retransmission identification information is added to the retransmitted document. However, only one of them may be configured. That is, regardless of normal transmission or resend, only the structure in which the document identification information indicating one document is added to the medium data to be sent may be used. On the other hand, the sent data does not include the document identification information and Alternatively, only the configuration in which retransmission identification information is added may be used.

Further, in the above embodiment, an example in which a numeral is displayed on the receiving side as the document identification information has been shown, but the present invention is not limited to this, and if the document can be identified,
Other symbols may be used. Then, even in the retransmission identification information, if the retransmission document can be identified, "retransmission"
It is not limited to the display such as. Also, in the second embodiment, not only the untransmitted data is automatically retransmitted after the failure recovery, but also the display control means 212 is provided as in the first embodiment, and when the failure occurs, the number of normally transmitted pages up to that point. May be displayed.

In the above embodiment, the transmission data management method is the number of pages of the medium, but the present invention is not limited to this. For example, the transmission range of the medium such as a chapter or paragraph in the case of a sentence is confirmed. If it is possible, management in other parts may be possible. Further, in the above-described embodiment, the method of reading all the data in the medium, storing the data in the medium data storage unit 221, and then transmitting the data is explained. However, even when the data in the medium is read and simultaneously transmitted, the reading is performed. Since the data is temporarily stored in the medium data storage unit 221, it can be applied in the same manner as the above embodiment.

[0035]

As described above, according to the facsimile communication apparatus of the first invention, the document identification information for identifying the data of the medium in the unit of document is added at the time of the transmission, and the document identification information for the unit of the document is received at the time of the reception. Since the identification display is provided, even if a plurality of documents are received on the receiving side, the documents can be easily identified.

Further, according to the facsimile communication apparatus of the second invention, since the retransmission identification information is added to the data of the medium to be transmitted after the recovery of the transmission failure, the transmission is interrupted due to, for example, a line failure. Even in this case, the document after the transmission failure recovery can be confirmed at a glance, and the work on the receiving side is easy.
