Note that in the sequence area 31, the sequence of the received command is registered. Thereafter, at the specified time registered in the transmission registration table, the telephone number 33 is output to the central office line trunk 1, and the image data stored in the image memory 7 by the facsimile procedure processing section 6 is sequentially sent to the other party's facsimile. Send and end the time-specified delivery process.

Functions such as substitute reception, broadcast communication, and time-specified delivery have been shown as examples above, but in addition to these, by providing a means to detect the 1300) Iz signal, it is possible to communicate with a facsimile network (no ringing) Incoming calls).

In this case, when a signal of 1300 Hz is received, it is determined that it is an incoming call from the facsimile network, and the subsequent processing is the same as in the above example.

[Description of Processing Procedures (FIGS. 4 to 7)] Next, the processing executed by the CPU 9 when a call is received on the central office line trunk 1 will be described below with reference to the flowchart in FIG. 4.

In step S10, when the central office line trunk 1 detects an incoming call as described above, the CPU 9 determines, based on the determination result from the facsimile determination processing unit 5, that if the call is a facsimile, in step S12, The status of the facsimile machines 16 is checked, and if they are free, a normal facsimile connection is made, but if all of them are in use, the process advances to step S14, and the central office line trunk 1 and the facsimile procedure processing unit 6 are connected to the communication path 2. A connection instruction is output to the communication path control section 8 in order to establish a connection. And step 31
In step S1B, a facsimile reception command is output to the facsimile procedure processing section 6 via the communication path control section 8 in order to perform the above-described proxy reception processing, and in step S1B, the communication between the facsimile procedure processing section 6 and the other party's facsimile machine is terminated. wait,
When the end signal and end result are input from the facsimile procedure processing section 6, it is determined in step S19 whether the reception has ended normally. If it is determined that the process has ended normally in step S19, the sequence (sequential number of the reception process) is entered in the reception registration table 21 of FIG. 3(a) in step S22.
is registered, and in step S20, a connection release instruction is output to the communication path control unit 8. Furthermore, if it is determined in step S19 that the termination is not normal (an example of a case in which the termination is not normal is that the image memory 7 is full, etc.), the reception error information (caller's dial number,
(incoming call arrival time, etc.) is stored in RAM II, and outputs a connection release instruction to the communication path control unit 8.

In addition, not only in the case of abnormal termination but also in the case of normal termination, the communication history (phone number of communication partner 9 communication time 1 number of image pages 0 communication time, normal/abnormal Information such as termination, etc.) may be stored in the RAM II and output to a display device such as a printer or facsimile when an operator instructs or when a certain number of histories have accumulated.

On the other hand, in step SIO, if the call is received to the telephone 15, the state of the telephone 15 to be connected is checked in step S24, and if the telephone 15 is free, an incoming call request is made to the normal telephone 15, but if all are in use, step In step S26, the status of the facsimile 16 is checked, and if it is idle and the facsimile is in a manual receiving state, the telephone of the facsimile 16 receives the call. However, if all the devices are in use, the busy tone connection is performed as before.

In addition to the above-mentioned incoming call processing, facsimile 16
The processing executed when the state changes from the busy state to the idle state will be described below with reference to the flowchart shown in FIG.

When one of the facsimile machines 16 becomes free, it is checked in step S30 whether the sequence is registered in the reception registration table 21, and if there is no registration, the process ends; The facsimile 16 and the facsimile procedure processing unit 6 are connected through the communication path 2, and a transmission command is output in step S36.

In response to this transmission command, the facsimile procedure processing unit 6 transmits the image data in the image memory 7 according to the input sequence, and outputs an end signal when the communication is completed. on the other hand,
The CPU 9 receives the end signal from the facsimile procedure processing unit 6 and inputs the end result, and determines whether the transmission has ended normally in step S39. If it is determined that the process has ended normally in step S39, the registration in the reception registration table 21 is deleted in step S32, a command to clear the image data is output to the facsimile procedure processing unit 6 in step S42, and the communication path is cleared in step S40. The controller 8 is instructed to release the connection.

In addition, if it is determined in step S39 that the end has not been completed normally, in step S41 a timer is set to retransmit after a certain period of time, or if there is another facsimile, a certain data is sent to another facsimile. After performing processing to enable retransmission of the image data, such as setting , the communication path control unit 8 is instructed to release the connection in step S40.

Through the above processing, the proxy reception function in this embodiment has been executed.

According to this embodiment, even if the connected facsimile is in use, the proxy reception function eliminates busy responses to the other party's facsimile.

Next, the process for transmitting an image from the facsimile 16 to the other party's facsimile will be described below with reference to the flowchart shown in FIG.

When a transmission start request is received from the facsimile 16, the processing code 22 in the setting table shown in FIG. If it is broadcast communication or time-specified delivery, the process proceeds to step S56, and if it is normal transmission, the process proceeds to step S54.
Check the status of the central office line trunk l. If the facsimile machine 16 is idle, the facsimile 16 is connected to the office line trunk 1 and normal facsimile communication processing is performed, but if it is in use, a connection with the facsimile procedure processing unit 6 is instructed in step S56. , outputs a reception command in step S58. As described above, this reception command causes the transmitted image data from the facsimile 16 to be transmitted to the facsimile procedure processing section 6.
The image data is stored in the image memory 7 via the . Then, in step S60, input the end of communication and the end result, and step S6
1 to determine whether it ended normally. If it is determined in step S61 that the termination is normal, the sequence 31, code 32, etc. are registered in the transmission registration table shown in FIG. Instruct.

If it is determined in step S61 that the process has not ended normally (for example, the image memory 7 is full and cannot be received), in step S63 an alarm is sounded to indicate that the image cannot be received from the facsimile 16 connected to the extension line, etc. Step S6
In step 2, the communication path control section 8 is instructed to release the connection.

The processing executed when the central office line trunk 1 is empty will be described below with reference to the flowcharts of FIGS. 7(a) and 7(b).

First, in step S70, it is checked whether there is a registration in the above-mentioned transmission registration table, and if there is no registration, the process ends. It is determined based on the code 32 whether this is the case. If the registration code is proxy transmission or broadcast communication, the process advances to step S76, and if it is time-specified delivery, the time in the data 33 and the time in the timer 12 are compared, and if it is not the specified time, the process ends. However, if they match, the process proceeds to step S76.Next, in step S76, in order to transmit the image data stored in the image memory 7 to the other party's facsimile, the facsimile procedure processing unit 6 and the central office line are connected. Trunk 1 is connected on communication path 2.

Then, in step S80, the destination telephone number registered in the data 33 area in the transmission registration table is sent from the office line trunk 1 via the call path control unit 8,
In step S82, a transmission command is output to the facsimile procedure processing section 6.Next, in step S84, the end signal and the end result inputted from the facsimile procedure processing section 6 are waited for.
After the communication with the other party's facsimile ends, the end result is determined in step S85. If it is determined that the process has ended normally in step S85, sequence 31, code 32, and data 33 in the facsimile transmission table regarding the image data sent immediately before are deleted in step S92, and the image data sent immediately before is deleted in step S94. A clear command is output to clear the data, and the process then advances to step S86.

If it is determined in step S85 that the end is not normal, the process directly advances to step S86, and in steps S86 and S88, the continuation of the broadcast communication process is determined by data 3.
It is determined based on the telephone number No. 3, and if there is, step S80
Returns the process to perform broadcast communication, and if there is no more information, go to step S.
Next, in step S90, the communication path control section 8 is instructed to release the connection, and in step S96, it is determined whether all the image data has been transmitted. Step S96
If it determines that all the image data has been sent, it does nothing and ends the process. In step S96,
If it is determined that there is image data that has not been transmitted, in step S98, a timer is set, etc. in order to retransmit the image data that has not been transmitted yet after a certain period of time, and processing that allows the retransmission of the untransmitted images is performed. After doing so, the process ends.

Through the above processing, the image data stored in the image memory 7 is transmitted, and the functions of broadcast communication and time-designated distribution are executed.

In addition, in this embodiment, when a facsimile without a telephone is used, a telephone 81 as shown in FIG.
When transmitting/receiving a signal requesting operator intervention such as an IP or PIN signal, the telephone 81 may ring and the facsimile communication intervention lamp 82 may be lit to notify that the call is a facsimile communication operator intervention request. good.

Furthermore, the facsimile transmission may be started by pressing the facsimile key 83 of the telephone 81 and then dialing, and when a call is detected, the main device 100 switches to the facsimile and transmits. In this case, which facsimile is to be sent? may be determined in advance, or may be designated by operating the telephone 81.

Furthermore, in this embodiment, an incoming call from a facsimile may be automatically determined by the facsimile determination processing unit 5, or the answering person of the telephone 81 may determine by sound that it is an incoming call from a facsimile. , facsimile key 83
It is also possible to judge by pressing .

According to this embodiment, since the telephone can be used in common for key telephone and facsimile communication, the cost of the key telephone system with facsimile function can be significantly reduced.

[Effects of the Invention] As described above, facsimile functions such as broadcast communication and time-specified delivery can be performed regardless of the function of the facsimile to which the facsimile is connected.
