DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments.
FIG. 1 is a view showing a facsimile apparatus according to one embodiment of the invention described in any one of claims 1 to 3 , and FIG.
FIG. 2 is a block diagram showing the control unit, and FIG. 2B is a block diagram showing the control unit.

First, the configuration will be described. In FIG. 1A, a network control unit 11 forms a line loop by controlling connection with, for example, a telephone line. The modulation and demodulation unit 12 modulates transmission data while demodulating received data. The data compression / reproduction unit 13 encodes the image information to be transmitted by a predetermined method, compresses the amount of information, and reproduces the encoded received image information into the original image information. The buffer unit 14 relays input / output of image information. The document reading unit 15 reads and scans a facsimile document. The image output unit 16 outputs the received facsimile image as a hard copy. The storage recording unit 17 as a storage unit stores image information for a plurality of pages related to transmission or reception. The control unit 18 controls the entire system of the facsimile machine.

The key input unit 19 inputs a transmission / reception operation, a transfer instruction input, a transfer destination telephone number, the necessity of receiving image information of the transfer request source, and the like. Transfer instruction storage unit 20
Stores the key-inputted transfer instruction and the necessity of receiving image information. A transfer destination telephone number storage unit (for reception) 21 as a transfer destination storage unit stores a telephone number of a transfer destination input by key. Here, as the transfer request means, the control unit 18 notifies the transmission side at the time of an incoming call of the transfer destination telephone number stored in the transfer destination telephone number storage unit 21 and requests transfer to the telephone number.

A transfer destination telephone number storage unit (for transmission) 22 as a transfer request storage means stores the transfer destination telephone number requested by the control unit 18. At the time of actual transfer, the selection signal generating unit 23 as a calling unit dials out the telephone number of the transfer destination stored in the transfer destination telephone number storage unit 22 and automatically makes a call. Here, the control unit 1
Reference numeral 8 denotes a change unit that changes the transmission destination of the image information from the transfer request source to the transfer destination when the selection signal generating unit 23 makes a dial call to the transfer destination. That is, the control unit 18 does not transmit the image information to the transfer request source, but transmits only the transfer destination.

FIG. 1B shows an embodiment in which the control unit 18 shown in FIG. 1A is realized by using a microcomputer. The key input unit 19, transfer instruction storage unit 20, transfer destination telephone This includes the number storage unit 21 and the transfer destination telephone number storage unit 22. In the figure, 31
Is a microcomputer (CPU), 32 is a ROM in which a system program is written, 33 is a RAM for system control, 34 is an electrically erasable and writable EEPROM or a RAM backed up by a battery,
35 is a system bus.

In the above configuration, the transfer instruction storage unit 20,
Transfer destination telephone number storage unit 21, Transfer destination telephone number storage unit 22
Are configured in the EEPROM 34. However, when transmitting the image information stored in the storage / recording unit 17, the control unit 18 as a transmission side prohibits the change of the transmission destination from the transfer request source to the transfer destination, and The image information is transmitted to both of them.

When transmitting image information that has not been stored to the storage / recording unit 17, the control unit 18 as a transmission side prohibits the change of the transmission destination from the transfer request source to the transfer destination, and The image information is accumulated in the accumulation recording unit 17 during transmission to the
After the transmission to the transfer request source is completed, the image information stored in the storage recording unit 17 is transmitted to the transfer destination. When a transfer request is received when transmitting image information that has not been stored, the information may be automatically stored in the storage recording unit 17 and transmitted to both the transfer request source and the transfer destination. I do not care.

Further, the control unit 18 notifies the transmitting side of the necessity of receiving the image information of the transfer request source itself stored in the transfer instruction storage unit 20 together with the transfer request as the necessity notification means of the receiving side. Then, the control unit 18 as a transmission side transmits the request to the transfer request source when the reception is requested. Next, an example of a control procedure for transmitting a transfer instruction and a transfer destination telephone number from the receiver to the transmitter will be described. The G3 facsimile transmission control procedure that is currently commonly used is T30 recommended by the CCITT (International Telegraph and Telephone Consultative Committee). In T30, there is a non-standard method that can be used freely by each manufacturer in order for the manufacturer to achieve a unique function. The non-standard function identification signal NS
There is F. In this embodiment, the non-standard function identification signal NS
In F, a bit for a transfer instruction (request) to the transmitter side,
A bit (display unit) for notifying the telephone number of the transfer destination and a bit indicating whether or not reception is necessary for notifying whether to continue or stop the subsequent reception are allocated and transmitted to the transmission side. The transmitting side receives this signal and determines the subsequent transmission procedure in consideration of its own conditions. For example, when there is no storage / recording unit 17 on the transmission side and transmission can be performed only once, even if there is a reception request, transmission to the transfer request source is not performed, and transmission to only the transfer destination is changed. Also,
If there is an accumulation recording unit 17 on the transmitting side, and transmission is possible to both the current receiver (transfer request source) and the receiver instructed to transfer (transfer destination), the transmission is performed according to the necessity of reception of the transfer request source. Execute

FIG. 2 is a diagram showing a G3 facsimile binary procedure defined by CCITT (International Telegraph and Telephone Consultative Committee) T30. When the facsimile control field is the non-standard function identification signal NSF, the facsimile control bit, the notification bit of the telephone number of the transfer destination, and the notification bit of the continuation or non-continuation of the subsequent reception are described above. It will be assigned in the information field. FIG. 3 shows signal names and code data used in the facsimile control field and the facsimile information field.

As shown in FIG. 2, the binary procedure of G3 facsimile is based on HDLC (High-level Data Link Controller).
ol) The format is specified as follows. That is, (1) The preamble has a flag sequence of 1 sec ± 15%
It is prescribed. (2) The flag code is defined as "01111110" and is transmitted from the left data, and no "0" insertion is performed. (3) The address field is defined as “11111111”. (4) In the control field, if the non-final frame is `` 110
00000 "and the last frame is defined as" 11001000 ". (5) The facsimile control field uses the signals shown in FIG. (6) Only the signal shown in FIG. 3 is used for the facsimile information field. (7) The CRC check field is a 16-bit CRC
Check pattern, that is, X16 + X12 + X5 + 1
Is used.

Next, the operation will be described. FIG. 4 shows a communication flow in the case where the transmitter side interrupts the current transmission / reception upon receiving a transfer instruction. The called side receiving side sends a called terminal identification signal CED from the called side receiving side to the calling side transmitting side. (Called Stati
on Identification), and non-standard function identification signal NS
F / Digital Identification Signal DIS (Digital Identification)
Signal), the disconnection command signal DCN (Disconnect) is transmitted from the transmission side to the reception side, and the communication ends.

Here, the transmission / reception interruption procedure shown in FIG.
This procedure is performed regardless of whether the interruption request is from the transmitting side or from the receiving side. For example, if image information is transmitted to the current receiver (transfer request source) and transmission to the transfer destination becomes impossible, interruption is determined by the transmission side, and the reception side becomes able to continue reception in the non-standard function identification signal NSF. The disconnection command signal DCN is transmitted. Then, transmission is performed only to the transfer destination.

On the other hand, when the receiving side requests interruption, the receiving side becomes unable to continuously receive in the non-standard function identification signal NSF, so that the transmitting side can transmit to both the transfer request source and the transfer destination. Even if there is, the transmission is interrupted by the disconnection command signal DCN and transmitted only to the transfer destination. FIG. 5 shows a communication flow in the case where the transmitter side receives the transfer instruction and completes the current transmission / reception. First, the called terminal identification signal CE
D, non-standard function identification signal NSF / digital identification signal DI
Reply S. Here, the transfer instruction is received by the non-standard function identification signal NSF and the receiver requests the continuous reception, and the transmitter can transmit, or according to the determination of the transmitter that has received the transfer instruction without the request for the continuous reception. If transmission is possible, transmission is performed to the transfer request source according to the procedure of FIG. 5, and after transmission is completed, transmission is also performed to the transfer destination. That is, the transmitting side sends the non-standard function setting signal NSS or the digital command signal DCS, and the training check TCF (Trai
ning Check) to determine the transmission rate. Next, the transmitting side sends a reception preparation confirmation signal CFR (Confirmation to Re
ceive), and sends a message (image information). After the end of message transmission, this communication flow is a single-page communication flow, so the message end signal EOM
(End of Message) and the message confirmation signal MC
After waiting for the reply of F, the communication is terminated by the disconnection command signal DCN.
