3 in the received information storage area. When reception from the calling side is completed, the line is released, and the subscriber number of the calling side stored in a predetermined area of the RAM 3 is replaced with the subscriber number of the transfer destination stored in the identification information storage area of the EEPROM 6. Is checked to see if it matches, if it does not match, the subscriber number of the transfer destination is automatically dialed, and after the line of the facsimile machine of the transfer destination is closed, it is received from the calling side and stored in the RAM 3 The received image data stored in the area is transmitted. That is, the reception data stored in the reception information storage area of the RAM 3 is transferred.

If the caller's subscriber number stored in a predetermined area of the RAM 3 matches the transfer destination's subscriber number stored in the identification information storage area of the EEPROM 6, a call is made to the transfer destination communication device. do not do. That is, the received image data stored in the received information storage area of the RAM 3 is not transferred.

After the line is closed in response to the input of the calling signal, if it is determined that the received signal is not an image data but a voice signal, a response message is sent out and a message from the calling side is sent to the RAM 3. And after communication is completed, the line is released.

The procedure of the transfer process in the transfer mode will be described with reference to the flowchart of FIG. This transfer process is started every predetermined time.

First, the CPU 1 determines whether there is a call (S1). Specifically, CPU 1 determines whether or not a call signal has been input to NCU 2 via telephone line 15.

If there is a call (S1: YES), the CPU 1
Extracts the calling subscriber number from the caller ID inserted during the static period of the calling signal (S2). Specifically, based on the data from the modem 4, the CPU 1 reads the subscriber number data of the calling communication device from the caller ID and stores it in the register file of the CPU 1. Then, the CPU 1 stores the calling subscriber number extracted in S2 in the RAM 3 (S3). Specifically, the CPU 1 stores the data of the subscriber number of the calling communication device stored in the register file of the CPU 1 in S2 in the RA.
It is stored in a predetermined area of M3. Then, the CPU 1
2 is controlled to close the line (S4). And CPU
1 determines whether or not facsimile reception is performed (S
5). Specifically, the CPU 1 checks whether the calling side is a facsimile apparatus or a telephone apparatus based on data from the modem 4.

For facsimile reception (S5: YE
S), the CPU 1 stores the received information in the RAM 3 (S6). Specifically, the CPU 1 stores the received image data in the received information storage area of the RAM 3. At this time,
The image signal input to the NCU 2 via the telephone line 15 is demodulated by the modem 4 and stored as it is in the reception information storage area of the RAM 3. That is, decoding by the codec 8 is not performed. This is because, when decrypted, the data amount becomes large and the storage capacity of the received information storage area is consumed. Then, the CPU 1 determines whether the reception has been completed (S7). Specifically, CPU 1
Based on a signal input to the NCU 2 via the telephone line 15, it is checked whether or not the calling line has been released.

If the reception has been completed (S7: YES),
The CPU 1 controls the NCU 2 to release the line (S
8). Then, the CPU 1 reads out the calling subscriber number from the RAM 3 (S9). Specifically, the CPU 1
3 reads out the subscriber number data of the communication device on the calling side stored in the predetermined area of the RAM 3 and stores it in the register file of the CPU 1. Then, the CPU 1
The subscriber number of the transfer destination is read from the ROM 6 (S1).
0). Specifically, the CPU 1 reads the data of the subscriber number of the transfer destination communication device stored in the identification information storage area of the EEPROM 6 and stores it in the register file of the CPU 1. Then, the CPU 1 determines whether or not the subscriber number of the calling party matches the subscriber number of the transfer destination (S11). Specifically, the CPU 1 stores the subscriber number data of the calling communication device stored in the register file of the CPU 1 in S9 and the subscriber number data of the transfer destination communication device stored in the register file of the CPU 1 in S10. Is checked to see if they match.

If the subscriber number on the calling side does not match the subscriber number on the transfer destination (S11: NO), the CPU 1
Makes a call to the transfer destination communication device (S12). Specifically, the CPU 1 controls the NCU 2 to close the line and dial the subscriber number of the transfer destination stored in the register file of the CPU 1 in S10. And C
PU1 determines whether a line is connected or not (S1).
3). Specifically, the CPU 1 checks whether the line of the communication device of the transfer destination is closed based on the state of the signal of the telephone line 15 input to the NCU 2.

If the line is connected (S13: YES),
The CPU 1 transmits the received information (S14). More specifically, the CPU 1 reads out the received image data from the calling side stored in the received information storage area of the RAM 3 in S6, modulates the data by the modem 4, and transmits the data to the telephone line 15 via the NCU 2. . Then, the CPU 1 determines whether the transmission has been completed (S15). Specifically, CPU
1 checks whether or not untransmitted received image data remains among the received image data from the calling side previously stored in the received information storage area of the RAM 3 in S6.

When the transmission is completed (S15: YES), C
PU1 controls NCU2 to release the line (S1
6), end the transfer process.

In S15, if the transmission has not been completed (S15: NO), the flow returns to S14 to continue the transmission.

In S13, if the line is not connected (S13: NO), the flow returns to S13 to wait for the line to be connected. Of course, in practice, if the line is not connected for a reason such as busy, a well-known process such as redial is executed. However, since this is not directly related to the gist of the present invention, it is omitted in the flowchart of FIG. doing.

In S11, if the subscriber number of the calling party matches the subscriber number of the transfer destination (S11: YE
S), the transfer process ends. Therefore, it is possible to prevent waste of transferring image data received from a transfer destination to the transfer destination.

In S7, if the reception has not been completed (S7: NO), the flow returns to S6 to continue storing the received image data.

If it is not facsimile reception at S5 (S5: NO), CPU 1 transmits a response message (S17). Specifically, the CPU 1 executes the EEPR
Among the response messages stored in the response message storage area of the OM6, for example, the voice data corresponding to the response message “I am out of the office.
The codec 8 decodes and D / A converts the
2 to the telephone line 15. And CPU1
Store the received information (S18). Specifically, C
The PU 1 stores the received voice data in the received information storage area of the RAM 3. At this time, NC via the telephone line 15
The audio signal input to U2 is converted into A /
D-converted and encoded. Then, the CPU 1 determines whether the reception has been completed (S19). Specifically, C
PU1 checks whether the calling line is released based on a signal input to NCU2 via telephone line 15.

If the reception has been completed (S19: YE
S), and proceed to S16. If the reception has not been completed (S1
9: NO), returning to S18 to continue storing the received voice data. Actually, the recording time of one recording is limited, and the line is automatically released after a predetermined time has elapsed. However, such processing is well known, and is directly related to the gist of the present invention. Since it does not matter, it is omitted in the flowchart of FIG.

In S1, if there is no call (S1: N
O), the transfer process ends.

In the above embodiment, the subscriber number of the caller is extracted from the caller ID. However, in a country or a region where the caller ID service is not provided, the caller ID is set after the line connection. The identification code, that is, the subscriber number may be output from the facsimile machine on the calling side, and may be detected by the facsimile apparatus on the receiving side.

In the above-described embodiment, the example in which the transfer destination is one communication device has been described. However, when the transfer destination is a plurality of communication devices, the reception information may be sequentially transmitted to those communication devices. . Then, at that time, if the transfer destination that was the calling side is included, it may be configured not to transfer to the transfer destination.

[0048]

As described above, according to the communication apparatus of the first aspect of the present invention, the transfer inhibiting means stores the caller's identification information in the identification information storage means by the identification information storage determination means. When it is determined that the reception information stored in the reception information storage unit is not transmitted to the communication device having the identification information, the reception control unit controls the transmission control unit so that the reception from the predetermined transfer destination is not performed. Since information can be prevented from being transferred, the transfer source can be prevented from wasting communication charges, and the transfer destination can be prevented from wasting recording paper or memory.
In addition, in the public interest, it is possible to prevent the traffic of the communication line from being wasted.

According to the communication apparatus of the second aspect of the present invention, in addition to the effect of the communication apparatus of the first aspect, even if the calling side does not transmit its own identification information, the receiving side can transmit the identification information. The caller's identification information can be identified.

Further, according to the storage medium of the invention described in claim 3, by operating the CPU of the communication device based on the stored program, the communication device described in claim 1 can be realized.
