If it is detected, the above-mentioned normal telephone incoming operation is performed, and if the CNG signal is not received and the handset 21 is not detached for a predetermined time, it is considered that the other party performs facsimile transmission, The normal facsimile reception operation described above is performed.

Next, the mode setting key 2 on the operation panel 22
The case where the built-in TAD mode is selectively set by 2d will be described in detail. First, the setup process of the built-in TAD mode in the facsimile apparatus 1 will be described based on the flowchart of FIG.

When the operator operates the function key 22c of the operation panel 11 to select the setup for performing various settings of the built-in TAD mode, the built-in TAD is selected.
AD mode setup processing is started.

When the setup process is started, first, the predetermined telephone number area 7a, the destination telephone number area 7b, the state storage area 7c and the function storage area 7d of the EEPROM 7 are cleared (S100). Next, as the three options, a fax-only state, a telephone-only state, and a shared state of the fax and the answering machine are displayed on the display 22a of the operation panel 22, and it is determined whether or not one of these is selected. (S101). If not yet selected (NO in S101), the process continues to wait until it is selected. On the other hand, if one of these is selected (S
If YES in 101), the selected branch is stored in the state storage area 7c of the EEPROM 7 (S103).

Next, three functions, that is, a paging function, a fax forward function, and a message forward function (hereinafter referred to as paging function) are displayed on the display 22a of the operation panel 22, and one of these is selected. Is determined (S105). Here, the paging function means a function of automatically calling the destination telephone number and sending a calling signal, and the fax forward function stores the destination telephone number in the image data storage area 9a of the image memory 9. The message forward function means a function of transferring image data, and the message forward function means a function of transferring the contents of the ICM stored in the voice memory 10 to a destination telephone number.

If one of these three functions is not yet selected (NO in S105), the process continues to wait until it is selected. On the other hand, if one of these three functions is selected (YES in S105), the selected function is stored in the function storage area 7d of the EEPROM 7 (S).
107). At this time, if the fax-only status is stored in the status storage area 7c of the EEPROM 7,
The message forward function cannot be selected.
Further, when the telephone-only state is stored in the state storage area 7c, the fax forward function cannot be selected. Furthermore, when the telephone-only state is stored in the state storage area 7c, the OG is stored in the voice memory 10.
When M is not recorded, an error is displayed on the display 22a.

Next, it is determined whether or not the telephone number of the call destination (transfer destination) is input by the ten keys 22b of the operation panel 22 (S109). If the destination telephone number has not been entered (NO in S109), the process waits until it is entered. On the other hand, if the destination telephone number is entered (S10
(YES in 9), this telephone number is stored in the destination telephone number area 7b of the EEPROM 7 (S111). In addition, a plurality of destination telephone numbers can be input.

Next, the built-in TAD mode processing will be described with reference to the flow charts of FIGS.

The built-in TAD mode process is performed by the operation panel 22.
The process is started by selectively setting the built-in TAD mode by the mode setting key 22d, and is executed based on the contents of the setup process.

When this process is started, as shown in FIG. 4, first, it is judged whether or not a calling signal is detected (S20).
1) If the call signal is not detected (NO in S201),
Wait until detected. If a call signal is detected (S
If YES in 201, then the temporary storage area 8a of the RAM 8 that stores the telephone number of the calling side is cleared (S20).
3) Then, it is determined whether or not the telephone number of the calling side is sent from the exchange 17 this time (S205). If the telephone number of the calling side is not sent from the exchange 17 (NO in S205),
If the caller telephone number is sent from the exchange 17 (YES in S205), the caller telephone number is stored in the temporary storage area 8a of the RAM 8 (S20).
7) and proceeds to S209.

In step S209, the contents stored in the status storage area 7c of the EEPROM 7 are searched for the fax-only status,
It is determined whether the telephone-only state or the fax / telephone sharing state is set, and in S209, the EE
If the contents stored in the state storage area 7c of the PROM 7 are in the fax-only state, steps S211 to S24 in FIGS.
Process 5 is performed.

That is, first, the line is closed (S211),
It is determined whether or not the calling telephone number is stored in the temporary storage area 8a of the RAM 8 (S213). If the calling telephone number is stored in the temporary storage area 8a of the RAM 8 in S213 (YES in S213), the telephone number that matches the calling telephone number is stored in the temporary storage area 8a of the RAM 8. It is judged whether or not it exists in the management data (S215), and if it exists (Y in S215).
S) Then, the difference between the current communication start time and the communication start time corresponding to the telephone number matched in S215 is calculated to determine whether or not the difference is within 15 minutes (S216). The difference is 1
If it exceeds 5 minutes (NO in S216), the buffer 5 and the image data storage area 9a of the image memory 9 store a predetermined amount of image data transmitted from another facsimile device (not shown) ( S221).

Then, the contents stored in the buffer 5 are decoded by the decoding unit 14, the bit image is developed and written in the bit image storage area 9b of the image memory 9 (S223), and then the contents stored in the buffer 5 are cleared. Yes (S225). Then, it is judged whether or not the image data transmitted from the other facsimile apparatus still remains (S227), and if it remains (YE at S227).
S), the process returns to S221 again, the next predetermined amount of the transmitted image data is stored in the image data storage area 9a of the buffer 5 and the image memory 9, and the same processing is performed thereafter. On the other hand, in S227, if there is no image data transmitted from the other facsimile apparatus (S2
If NO at 27), the line is opened (S229).

By the processes of S221 to S229, the communication contents of a predetermined capacity are sequentially stored in the image data storage area 9a of the image memory 9, and finally the entire contents of the communication are stored. The contents written in the bit image storage area 9b of the image memory 9 in S223 are sequentially output to the printer 15. Therefore, the printer 15 finally records (prints) the entire content of the communication on the recording paper.

After the processing of S229, it is determined whether or not the content stored in the function storage area 7d of the EEPROM 7 is the fax forward function (S231, see FIG. 5). In S231, if the stored content of the function storage area 7d of the EEPROM 7 is the fax forward function (YES in S231), the line is closed and the EEPROM 7 is closed.
The destination telephone number stored in the destination telephone number area 7b is automatically called (S233), and after confirming that the destination facsimile machine has received it by exchanging signals in the communication protocol, the image in the image memory 9 is displayed. The image data stored in the data storage area 9a (entire content of communication) is transmitted (S235). After that, the line is released (S23
7) The image data storage area 9a of the image memory 9 is cleared (S239), and the process returns to S201.

On the other hand, in S231, if the stored contents of the function storage area 7d of the EEPROM 7 is not the fax forward function (NO in S231), since it is the paging function, after the line is closed, the destination telephone number area of the EEPROM 7 7b is automatically called to the destination telephone number stored in 7b (S241), and the ringing signal is continuously transmitted until a predetermined time has passed (S243), and when the predetermined time has passed (S243).
YES), the line is opened (S245), and the image memory 9
Clear the image data storage area 9a (S239),
It returns to S201 again.

If the telephone number that matches the telephone number on the calling side does not exist in the management data stored in the temporary storage area 8a of the RAM 8 in S215 (N in S215).
O), the process proceeds to S221. If the calling telephone number is not stored in the temporary storage area 8a of the RAM 8 in S213 (NO in S213), the process proceeds to S221.

On the other hand, the time between each communication is 15 in S216.
If it is determined that the time is within the minute (Y in S216
S) Then, it is judged that the once transferred image data is transferred again via another facsimile apparatus, and it is completely meaningless to transfer the image data again. Therefore, in this case, the normal facsimile reception operation described above is performed (S217), and then the line is opened (S217).
219), and the process returns to S201 again.

The receiving operation of S217 can be deleted because it is the data already received once.
This is a process for confirmation when image data different from the transferred image data is sent.

When the paging function is set (NO in S231), after the line is released in S245,
The following processing may be performed before clearing the image data storage area 9a in S239. That is, it is determined whether or not there is a request for remote control communication (for example, retrieval communication) from the destination telephone number that is automatically called, and if there is no request for remote control reception, wait until there is a request. If there is a request to perform remote control communication, the line is closed and the contents stored in the image data storage area 9a of the image memory 9 (the entire contents of communication) are transferred.
The line may be opened after the transfer is completed, and then the process of S239 may be performed.

Next, in S209 of the flow chart of FIG. 4, if the stored contents of the state storage area 7c of the EEPROM 7 is a telephone-only state, the processes of S301 to S317 of FIG. 6 are performed.

That is, the line is closed (S301), and the OGM stored in the voice memory 10 is sent to the calling side (S30).
3) Subsequently, the ICM sent from the calling side is stored in the voice memory 10 (S305), and the line is released (S30).
7). After that, the telephone number that matches the calling telephone number is R
It is determined whether or not it exists in the management data stored in the temporary storage area 8a of the AM 8 (S309), and if it exists (YES in S309), this communication start time and S30
The difference with the communication start time corresponding to the matched telephone number in 9 is calculated to determine whether or not the difference is within 15 minutes (S3).
10). Whether the difference exceeds 15 minutes (N in S310
O), or if the telephone number that matches the telephone number on the calling side in S309 does not exist in the management data stored in the temporary storage area 8a of the RAM 8 (NO in S309), then the function storage of the EEPROM 7 is performed. It is determined whether the content stored in the area 7d is the message forward function (S311).

At S311, if the content stored in the function storage area 7d of the EEPROM 7 is the message forward function (YES at S311), the line is closed and the EEPROM is closed.
The destination telephone number stored in the destination telephone number area 7b of M7 is automatically called (S313), and the ICM stored in the voice memory 10 is repeatedly transmitted a predetermined number of times (S31).
5). This allows the contents of the ICM to be transmitted to the other party without confirming that the other party picked up the receiver. After that, the line is released (S317), and S20 is again performed.
Return to 1. On the other hand, in S311, if the stored content of the function storage area 7d of the EEPROM 7 is not the message forward function (NO in S311), since it is the paging function, the processing from S241 onward in FIG. 5 is performed.

Even if the calling telephone number is not stored in the temporary storage area 8a of the RAM 8, NO in S309.
Is judged.

On the other hand, in S310, the time between each communication is 1
If it is determined that it is within 5 minutes (Y in S310
ES), and again returns to S201.

Next, in S209 of the flow chart of FIG. 4, if the stored contents of the state storage area 7c of the EEPROM 7 is a shared state of a facsimile and a telephone, S40 of FIG.
The processes of 1 to S405 are performed.

That is, the line is closed (S401), it is judged whether or not the other side has received a CNG signal indicating that the facsimile transmission is to be performed (S403), and if the CNG signal is received (YES in S403). , The processing from S213 onward in FIG. 4 is performed. On the other hand, if the CNG signal is not received (S4
(NO in 03), it is determined whether a predetermined time has elapsed (S4
05), if the predetermined time has not passed (N in S405)
O), the process returns to S403, and if a predetermined time has passed (S4
(YES in 05), the other party is considered to be a telephone, and the processes from S301 onward in FIG. 6 are performed.

According to the above facsimile apparatus 1, in the setup process of the built-in TAD mode, either the facsimile dedicated state or the shared state of the facsimile and the telephone is set, and the callee telephone number is set. Only when the required fax is sent
Paging (automatic call only) or fax forward (automatic call and transfer of the contents of the facsimile) is performed to the destination telephone number, and the facsimile transferred from the transfer destination is transferred to the transfer destination again. There is no useless communication such as transfer.

In the built-in TAD mode setup process, if either the telephone-only state or the shared state between the facsimile and the telephone is set and the telephone number to be called is set, necessary voice data can be sent. Only when the call is received, paging (automatic call only) or message forward (automatic call and transfer ICM) is performed to the destination telephone number, and voice data transferred from the transfer destination There is no useless communication such as transferring the data to the transfer destination again.

Therefore, for example, assume that B is set as the transfer destination in the facsimile machine of A, C is set as the transfer destination in the facsimile machine of B, and A is set as the transfer destination in the facsimile machine of C. . At this time, when image data is transmitted from the D facsimile machine to the A facsimile machine and the image data is transferred to the B facsimile machine, the B facsimile machine transfers the image data to the C facsimile machine. Transferred. Further, the image data is transferred again to the facsimile machine of A through the facsimile machine of C.

This operation is repeated again, but when the image data is transferred again from the C facsimile machine, it is determined that the image data is sent from the same location, and the time between the two communication is set. And the result is 15
Since it is not transferred again within the time, the same image data will not be repeatedly transmitted any more, and unnecessary notification (automatic call or transfer of communication contents) will not be performed.

Further, if the fax forward function or the message forward function is set in the built-in TAD mode setup processing, the contents of the facsimile and the contents of the telephone from the valid party can be known to the predetermined destination as usual. The effect that it can be dealt with promptly based on the content is obtained.

Further, in the setup process of the built-in TAD mode, when the fax forward function is set, only the information from a valid partner is transferred, so that the recording paper is not wastefully used at the transfer destination. In addition, the problem that even if the line of the facsimile apparatus 1 is closed for transmitting unnecessary information and truly useful information is transmitted, it cannot be immediately dealt with, is solved.

Needless to say, the present invention is not limited to the above embodiments and can be implemented in various modes without departing from the technical scope of the present invention.

For example, in the above embodiment, the telephone number stored in the temporary storage area 8a of the RAM 8 was the calling side telephone number (CALLER ID) sent from the exchange, but the present invention is not limited to this. During the transfer of signals by TSI
It may be the telephone number of the calling side included in the transmission terminal identification signal sent as a signal. In this case, S20 of FIG.
The processes of 5 and S207 are performed after S211.

When the fax forward function is set in the setup processing of the built-in TAD mode, the transmitted image data is simply stored in the image data storage area 9a of the image memory 9 during the processing of S221 to S227. The recording paper may not be printed.

Further, in S216 and S310, the time between each communication is determined based on the communication start time, but this may be based on the communication end time or a combination of the communication end time and the communication start time.

The time between communications in S216 and S310 is not limited to 15 minutes, and the time required for one transmission varies depending on the capability of the facsimile machine, the resolution at the time of transmission, the data compression rate, the number of sheets to be transmitted, etc. Therefore, the operator may set it according to these factors, or the time may be automatically selected.

Further, in the above embodiment, the present invention is effectively used when the transfer destinations are set so as to form a loop among the facsimile machines at three or more places. It can also be used when the transfer destinations of the other parties are set.

Further, identification data for adding a predetermined mark, for example, ◯, to the upper right of the image data to be transmitted is stored in a predetermined area of the image memory 9, and is stored in the image data storage area 9a of the image memory 9. When the transferred image data is transferred, its identification data is added and transmitted. At the transfer destination, since the transferred image data is received with the identification data added, the identification data will not be added even when this image data is transferred via another facsimile machine. If it is determined by the CPU 3 whether or not there is data, it is possible to know whether or not the data has been transferred from the own facsimile device. As a result, if identification data is detected in the received image data, the image data is not transferred, and unnecessary communication is not repeated.

In this case, since it is possible to immediately determine whether or not the image data is the image data to which the identification data is added, the image data once transferred is sent again. Therefore, as in the above-described embodiment, the same facsimile apparatus is used. It is possible to cancel unnecessary communication earlier than when the transfer is stopped for the first time when two transmissions are made.

Further, in the case of audio data, a signal of a predetermined frequency is added to the audio data and transferred, and it is detected by using a filter whether or not the received audio data contains a signal of that frequency. As a result, it is possible to prevent unnecessary communication from being repeated like the image data.

Further, in order to detect that the image data transferred from the own facsimile device is sent again via another facsimile device, the transferred image data is stored for a predetermined time and the image data is received. Sometimes comparing the received image data with the transferred image data,
The transfer may be stopped when it is determined that they are the same image data.

Further, in the case of having a function of adding the sender of the own facsimile apparatus to the upper part of the transmission data at the time of transmission, the sender is added at the time of transfer and transmitted, and the image added by the sender at the time of transfer is received. It may be determined whether or not it is added to the data, and whether or not to transfer the data may be determined.

[0085]

As is apparent from the above description,
According to the communication device of the first aspect of the present invention, whether to automatically call the predetermined destination telephone number based on the detection result of detecting that the data having the same content is received within the predetermined period. Since it is determined whether or not there is an effect that unnecessary communication can be prevented.

Further, according to the communication apparatus of the present invention, the telephone number of the calling side sent through the line and the time of communication are stored for each data communication, and this time, The calling party telephone number sent through the line is compared with the stored calling party telephone number, and the period between each communication from other communication devices is detected. Based on this, it is determined whether or not to automatically make a call to a predetermined destination telephone number, so that it is possible to prevent unnecessary communication from being repeated.

Further, according to the communication device of the present invention, when there is a calling telephone number that matches as a result of the comparison, the time at which the communication corresponding to the calling telephone number is performed. When it is detected that the time between each communication is within a predetermined time based on the time when the communication corresponding to the calling party telephone number sent through the line this time is performed,
Since an automatic call is not made to a predetermined call destination telephone number, it is possible to reliably prevent unnecessary communication.

According to the communication device of the present invention, when the data from the other communication device is transferred to the predetermined destination telephone number, the predetermined identification data is added to the data. When receiving data from another communication device, it is determined whether or not the predetermined identification data is added to the data, and based on the result of the determination, it is automatically issued to a predetermined destination telephone number. Since it is determined whether or not to call, it is possible to prevent unnecessary transfer of unnecessary data repeatedly.
