[Prior Art] Conventionally, in a facsimile machine that transmits by switching between two lines, when making a telephone call, the same operator call processing is performed on either line.

Furthermore, the built-in modem is configured to use the same line parameters (communication setting parameters) for each line even if the lines used for facsimile transmission are different.

[Problems to be Solved by the Invention] For this reason, there is no distinction between internal and external operator calls, and the same operator call sound is output, so when an operator call is made, it is difficult to tell which line is calling the operator, and the appropriate operator call is not made. The drawback was that it was difficult to respond.

Furthermore, modems use the same line parameters for communication settings when communicating with internal lines or external lines, resulting in the following drawbacks.

(1) Although the line quality is different for internal lines and external lines, the same modem line parameters, such as ATT and NL values, are used, so communication errors and image errors may occur because the values do not match the required or optimal values for the line. Likely to happen.

(2) Even though the modem fallback rate differs depending on the line, if transmission starts at the same modem speed, extra time is required for fallback [Means for Solving the Problems] The present invention solves the above-mentioned problems. It was developed with the following purpose as a means to solve the above-mentioned problems.

[Function] According to the above configuration, by providing a means for outputting a different operator call sound for each line, operator operation can be facilitated and an appropriate response can be taken.

In addition, by storing the parameters of the line to be connected in advance in memory, the line parameters are automatically selected when the line is selected, and communication errors and communication time can be reduced by using the optimal parameters. can.

The call origination process (facsimile transmission process) of this embodiment having the above configuration will be explained below with reference to the flowchart of FIG.

First, in step S1, the original 25 is set at the original setting position of the scanner section. Then, in step S2, the operation panel 6
Input an instruction to send an outside line using key 7. In response to this instruction input, the CPU activates the scanner section, and reads the transmitted original on the original 25 using the CCD I/O. This read data is primary encoded by the primary encoding circuit 11 and stored in the image memory 4. Thereafter, in step S4, a call is made to the other party's device. That is, the outside line 31 is selected by the inside/outside line changeover switch 23, and the modem 19 and outside NCU 23 are connected. The outside NCU 23 dials the outside telephone line 31 according to a predetermined procedure and connects it to the other party's facsimile 3 on the outside line. When the other party's facsimile 32 responds and a communication path is established, the process advances to step S5, where the modem 19 sends the CCITT
Performs pre-transmission procedure processing in GIII facsimile specified in . In the image transmission phase, the process advances to step S6, and the transmission data stored in the image memory 4 is transmitted to the other party's facsimile 32.

This is done in the following steps.

First, primary encoded image data is read out from the image memory 4, decoded by the primary code decoding circuit 16, and stored in the RAM.
18. Next, the secondary code decoding circuit 17 decodes it into the MR or MH code requested by the facsimile 32 on the outside line, modulates it in the modem 19, and transmits it from the outside NCU 23 to the facsimile 32 on the outside line via the telephone line 31. Send. After transmitting the desired data in this manner, the process proceeds to step S7, and post-transmission procedures are performed using the modem 19 and external NCU 23 according to the G3 facsimile procedure defined by CCITT. Then, in the following step S8, it is checked whether the post-procedure process is a post-operator call procedure, and if it is a post-operator call procedure, the process proceeds from step S8 to step S9, where operator call processing is performed and an operator call from the outside line 31 is performed. The speaker drive circuit 35 outputs a call sound peculiar to an outside line operator call indicating that
The speaker 36 outputs a distinctive call sound that can be easily recognized as an operator call from an outside line.

On the other hand, if it is determined in step S8 that it is not the procedure after the operator call, the process proceeds to step SIO, where the CML relay 100 is deenergized, the DC loop of the outside line 31 is opened, and the line is restored.

On the other hand, the other party's facsimile machine 28 has an extension line.
In this case, communication control is performed using the internal NCU 24, and when there is an operator call from the internal NCU 27,
The speaker driving circuit 35 is instructed to output a call sound peculiar to an extension operator call from the speaker 36.

The details of this operator call processing will be explained below with reference to FIG.

In the case of operator call processing (telephone call processing), the process advances to step S20 shown in FIG. 4, and it is checked whether or not the outside line 31 is currently communicating by facsimile. If facsimile communication is in progress using the outside line 31, the process advances to step S21, and the outside line 31
The H relay (off-hook relay) 102 of the CU 23 is driven to connect the outside line 31 and the telephone 104.

Then, in step S22, the off-hook detection circuit 103 checks whether the telephone 104 has responded and detected off-hook. If there is no response and the line is not off-hook, the process proceeds to step S23, where the speaker drive circuit 35 is instructed to output an outside line operator call sound, which is a unique voice notification sound indicating that there is an operator call from the outside line 31, from the speaker 36. . Then, in step S24, it is determined whether a predetermined time has elapsed. If the predetermined time has not elapsed, the process returns to step S22, and if the off-hook is not performed by the elapse of the predetermined time, the above process is repeated and the outside line operator call sound continues to be produced.

Here, if a predetermined period of time has elapsed since the start of the operator call, the process proceeds from step S24 to restep S2.
Step 5 instructs the speaker drive circuit 35 to stop transmitting the outside line operator call sound. Subsequent step S26
Then, the H relay 102 is opened, the outside line 31 and the telephone set 104 are disconnected, and the operator call processing is ended. Thereafter, the process is terminated by notifying the communication partner of the operator's non-response.

On the other hand, if the telephone 104 responds to the outside line operator call tone and off-hook is detected, step S
22, the process proceeds to step S30, and if necessary, notifies the other party of off-hook (sends an operator response signal) and instructs the speaker drive circuit 35 to stop the speaker drive,
Stops the operator call tone. And step S3
1 turns off the CML relay 100 and connects it to the facsimile side (N
Open the DC loop forming circuit formed on the CU side,
After that, the line is maintained by a DC loop formed by the answering telephone. This makes it possible to talk using the connected telephone. Thereafter, a call is made in step S32, and when the call ends, the telephone is put on the hook, thereby opening the DC loop formed in the line and restoring the line.

Also, in step S20, if the communication is not in progress with the extension line 31, but the extension line 2
7, the process advances to step S35, and the H relay (off-hook relay) 102 of the inner NCU 24 is driven to connect the extension 27 and the telephone 114. Then, in step S36, the off-hook detection circuit 113 connects the telephone 114 to the telephone 114.
responds and detects off-hook. If it is not off-hook, the process proceeds to step S37, instructing the speaker drive circuit 35 to connect the extension 26 from the speaker 36.
Outputs an extension operator call sound, which is a unique tone notification sound indicating that there is an operator call from another person. Then, in step S38, it is determined whether a predetermined time has elapsed. If the predetermined time has not elapsed, the process returns to step S36, and if the phone is not off-hook by the time the predetermined time elapses, the above process is repeated and the extension operator call sound continues to be output. If a predetermined period of time has elapsed since the start of the operator call, the process advances from step S38 to step S25, instructs the speaker drive circuit 35 to stop transmitting the extension operator call sound, and continues in step S2.
6, the H relay 112 is released, the extension 27 and the telephone 14 are disconnected, and the operator call processing is completed. Thereafter, the process is terminated by notifying the other party of the operator's non-response.

On the other hand, if the telephone 114 responds to the extension operator call tone and off-hook is detected, the process advances from step S36 to step S30, and the same processing as for the outside line 31 is performed.

FIG. 5 shows an example of the output of the outside line operator call sound from the speaker drive circuit 35 described above. As shown in Fig. 5, 1100t(z.

1500) 1z, 2100Hz sound is output, there is a silence state for 1 second, and then the above sounds are repeatedly output.

FIG. 6 shows an example of the output of the extension operator call sound from the speaker drive circuit 35 described above. As shown in Figure 6, 2100Hz every second.

1500) Output the sound of 1z, 1100Hz, 1
It is silent for a second, and then the following sounds are output repeatedly.

The above sound is an example of the extension/external operator call sound, and any sound may be used as long as the two call sounds can be distinguished.

Furthermore, although the above explanation has been made using the example of transmission using the outside line 31, when transmitting manuscript data to an extension facsimile (for example, facsimile 28) using the extension 27,
In step S4, the internal NCU 24 is used to call the extension facsimile 28, and the data in the image memory 4 is transmitted to the other party's facsimile 28 via the extension 27, extension switch 6, etc.

Details of the calling operation of the NCU in step S4 described above will be described below.

When making an outside line call, the outside line is selected by the inside/outside line changeover switch 23, the H relay 102 of the outside NCU 23 is turned on, and the off-hook detection circuit 103 is activated to confirm the on-hook state. Next, CML relay 10 of outer NCU 23
0 is turned on. Next, when the line is designated as "DP" (when the connected line is a dial line), the P relay 101 of the outside NCU 23 is turned on/off according to the dial number (destination telephone number) for dialing. It is turned off and a dial pulse corresponding to the number is sent to the outside line.

On the other hand, if the line is designated as "PB" (if the connected line is a button telephone line), the modem is activated and a DTMF signal corresponding to the telephone number is sent out to the outside line via the outside NCU 23. A DTMF signal is sent out. Note that if the modem does not have a built-in DTMF signal generating circuit, this DTMF signal generating circuit may be provided separately.

Further, when making an extension call, the extension is selected by the internal/external line changeover switch 23, each relay of the internal NCU 24 operates in the same manner as an external line, and the extension is dialed. In this way, a call is made to the destination, and the destination specified by the dial number is called. When the other party responds to this, the polarity of the connection line is reversed, and by detecting this polarity reversal, the other party's response can be detected.

Next, the process when a call is received from the outside line 31 (or extension 27) will be described below with reference to the flowchart shown in FIG.

In step S41 of the CPU 1, the called detection circuit 1 of the outer NCU 23 (or inner NCU 24) is activated via the NCU control unit 21.
05 (or 115) detects a called signal.

If a called signal is detected, the process advances from step S41 to step S42, and it is checked whether the called signal has been continuously received for 3 seconds. When this called signal (ringing signal) comes, a ringing tone is output from the connected telephone 104 (or 114). Therefore, the telephone is off-hook during this 3 seconds, and the off-hook detection circuit 103 (or 113
) detects off-hook, the telephone responds and the process ends. Thereafter, a call will be made between the answering telephone and the line.

If the telephone does not respond even after receiving the open call signal for 3 seconds, the process advances from step S42 to step S43, and it is determined whether the call signal has come from an outside line or an extension line.

If the call is from an outside line, the process advances from step S43 to step S44, where it is checked whether facsimile communication using the extension 27 is being performed. When not communicating using an extension, facsimile reception is possible.
In step S45, the H relay 102 of the outside NCU 23 is switched to disconnect the telephone from the line, and the CM L I) relay 1
00 to close the contact and form a DC loop in the outside line 31 to respond to the call. Then, in step 346, a known facsimile automatic reception process is executed.

On the other hand, if the extension 27 is in communication in step S44 and the facsimile unit of this embodiment is in use on the extension 27 side, it is not possible to receive a facsimile from the outside line 31, so the process goes to step S20, and as in step 345, first NCU2
The CML relay 100 of No. 3 is driven to form a DC loop on the outside line 31 to respond. Next, in step S21, the state is maintained for 2 seconds, and then in step S22, the outer NCU 2
The CML relay 100 of No. 3 is deenergized, the DC loop formed in the outside line 31 is released, and the line is restored.

This allows the calling device to immediately detect abnormal termination.

On the other hand, if it is determined in step S43 that the call is not from the outside line 31 but from the extension 27, the process proceeds from step S43 to step S55, where it is determined whether or not the outside line 31 is in communication. If the outside line 31 is not in communication, facsimile reception is possible, and the process advances from step S55 to step S56, where the internal NC
Switch the H relay 112 of U24 to disconnect the telephone from the line, drive the CML relay 110 to close the contact,
A DC loop is formed on the extension 27 to answer the call. Then, in step S57, a known facsimile automatic reception process is executed.

On the other hand, if the outside line 31 is in communication in step S55 and the facsimile unit of this embodiment is being used on the outside line 31 side, the process advances to step S61 because it is not possible to receive a facsimile from the extension 27. NCU2
4 CML relay 110 is driven to form a DC loop on extension line 27 to respond. Next, in step S61, the state is maintained for 2 seconds, and then in step S62, the inner NCU 2
The CML relay 110 of No. 4 is deenergized, the DC loop formed in extension No. 7 is released, and the line is restored. This allows the calling device to immediately detect abnormal termination.

Note that the above-mentioned outside line automatic reception process (step 546)
Specifically, this is performed according to the following control.

(1) Connect to the facsimile machine 22 of the external line via the external telephone line 21 and line II 2130.

(2) Select the outside line with the inside/outside line changeover switch 23 and
Connect CU23 and modem 19.

(3) Reception is started according to the Gm facsimile procedure defined by CCITT, and thereafter the received data is demodulated by the modem 19.

(4) In the image reception phase, the MR or MH code data transmitted from the external facsimile 32 is decoded by the secondary code decoding circuit 127 and stored in the buffer RAM 1.
It is stored in 8.

(5) The primary code decoding circuit 16 reads data from the buffer RAM 18, performs primary encoding, and stores the data in the image memory 18.
Store it in

(6) The primary set encoding circuit 14 reads image data from the image memory 4, performs primary set encoding, and then sends the decoded data to the thermal head 13.

(7) The thermal head 13 prints the received image data on the recording paper 12.

(8) The modem 19 performs post-reception procedures in accordance with the Gnl facsimile procedure defined by CCITT.

(9) Outside NCU 23 is outside line 31 (7) CML relay 10
0 is deenergized to release the DC loop and disconnect the line.

On the other hand, when an extension is automatically received, the same processing as described above is performed by the extension NCU 24, the extension telephone line 27, and the extension facsimile 28. In this case, the extension and outside lines are exchanged and processed in the above operation.

As explained above, according to this embodiment, by providing a means for changing the ringing sound of an operator call for each line, the operator's operation is facilitated.

In the above explanation, an example was described in which the notification sound from the speaker 36 is changed and outputted in order to identify whether the operator call is from the extension 27 or the outside line 31, but this embodiment is based on the above example. However, the present invention is not limited to this, and the control may be such that a display is displayed on the display 8 on the operation panel to distinguish whether the operator call is from the extension 27 or the outside line 31. Alternatively, this may be done using the lamp 9, and it goes without saying that the above display may be done simultaneously with the identification of the speaker sound.

Furthermore, it may be possible to store multiple extensions or external lines and output a different call tone for each line so that it is possible to recognize which external line or extension the operator call is from.In particular, if multiple dedicated lines are used, This is effective when stored.

[Second Embodiment] The above explanation has been about control during operator calls, but in addition to the above configuration, the following controls are performed to improve communication reliability and communication efficiency.

In other words, in most cases, the line quality differs depending on the connected line (for example, an internal line and an external line), and if transmission is performed using the same line parameters for lines with different quality, transmission errors may occur. The frequency of transmission increases, and communication efficiency decreases because transmission speeds must be reduced. This embodiment is intended to eliminate this problem.

The line parameters for each line stored in the apparatus of this embodiment are held and registered in RAMa, and at the time of transmission, transmission is performed in accordance with the registered line parameters.

Therefore, communication setting parameters (line parameters) are stored and registered in the RAM 3.

These parameters may be held for each storage line if the line quality is different, or unique parameters may be registered for each called destination. For example, when one-touch dial registration is performed, unique parameters are registered for each registered call destination, and when a one-touch dial call is made, the corresponding line parameters are set in the same way as the process described later. All you have to do is start communication accordingly.

The following description will be made using an example in which line parameters unique to the extension line 27 and the outside line 31 are held.

In this embodiment, for example, the line parameters shown in Fig. 8 are registered, and the ATT for internal/external lines is (4dBm/8dB
m), the transmission speed of the modem is (9600dps/
Parameters such as 7200 s d p s ) are registered.

In the call processing, in the case of an external call, the third
In executing the pre-procedure process in step S5 following the process in step S4 in the figure, communications will be started in accordance with the outside line parameters shown in FIG.

In the case of FIG. 8, the ATT value is 8 dBm, the modem speed is 7200 bps, etc., and communication will be performed in accordance with these parameters in the pre-procedure process.

In this case, if the modem speed in the DIS signal of the other party's facsimile during pre-procedure processing is 7200 dps or more, the modem speed is instructed to be 7200 dps with the DOS signal. However, the modem speed of the other party's fax machine is 720.
If the speed is 0 bps or less, the setting will be reset to a modem device that can be used by the other party's device.

In the image transmission phase, the primary encoded image data is sent from the image memory 4 to the primary code decoding circuit 16, decoded, and stored in the buffer RAM 18.

Next, in the secondary code decoding circuit 17, the modem 1
9 to the other party's facsimile 32 via the external NCU 23 and external line 31. In other words, if the modem's NL value is previously registered as 4dB, the modem will receive 4dB.
he instructs.

In this embodiment, if the other party's facsimile machine does not respond to a dial call and memory transmission is specified, redial waiting processing and redial re-calling processing are executed using the pre-registered redial count value. Ru.

On the other hand, if the call is to an extension, the other party's facsimile device (for example, 28
) will be communicated with.

Further, even when a call is received from the line, pre-procedure processing and communication are performed according to the set line parameters. At this time, the output level of the modem 19 is set to the pre-registered AT level.
The T value is set. If the start speed of the modem is registered in advance as 9600 dps, the modem speed in the DIS signal is designated as 9600 dps.

Also, if the modem start speed is registered as 4800 dps in advance, the modem speed in the DIS signal is set to 480 dps.
Indicate 0dps.

In the image reception phase, MR or MH code data transmitted from the other party's facsimile is received by the modem 19 according to pre-registered parameters, decoded by the secondary code decoding circuit 17, and stored in the buffer RAM 18, that is, by the modem. If the NL value of is registered as 4 dB in advance, 4 dB is instructed to the modem.

Then, facsimile transmission is performed, and in post-procedure processing, if the number of error lines of the received image is greater than the predetermined number of error lines of the outside line, an RTN signal is sent.

As explained above, according to this embodiment, by storing the parameters of the line to be connected in advance in the memory, the parameters of the line are automatically selected when the line is selected, and the optimum parameters are used. Communication errors and communication time can be reduced.

In this example, we have explained the case where there are two lines stored, one internal line and one external line, but each line can be two or more lines, or when multiple internal lines or external lines are stored. It is clear that the same effect can be obtained even if there is such a method, and it is included in the scope of the present invention.

[Effects of the Invention] As described above, according to the present invention, by providing a means for outputting a different operator call tone for each line, operator operations can be facilitated and appropriate responses can be taken.

In addition, by storing the parameters of the line to be connected in advance in memory, the line parameters are automatically selected when the line is selected, and communication errors and communication time can be reduced by using the optimal parameters. can.
