Next, this embodiment will be described in detail with reference to the flow charts showing the control operation of the CPU 1 in FIGS.

The programs to perform the following operations are stored in ROM2. First, when a call comes in to this machine, Step S1
It is discriminated whether or not there is a call signal (hereinafter, referred to as Ci) for 6 seconds. If there is no Ci for 6 seconds continuously, the signal is turned off. The Ci detection in this embodiment is performed by the line control unit by calling signal (C
This is performed by the CPU 1 discriminating whether or not i) has been detected. Step S2 determines whether or not the slide switch 21 in FIG. 2 is set to automatic reception. If it is not automatic reception, it goes to step S3. If it is automatic reception, it forms a closed loop of the line 17 (captures line) and then goes to step S5. move on. Step S3
Then, it is determined whether the slide switch 21 shown in FIG. 2 is in the manual reception mode, and if the manual reception mode is selected, it operates as a normal telephone and rings the bell for operator call.

If the slide switch 21 is automatically received, the process proceeds from step S2 to step S5. If the slide switch 21 is tamper-proof, the process proceeds from step S3 to step S4. At step S4, it is determined whether Ci is detected for 9 seconds (15 seconds in total) following step S1,
If Ci is not detected for 9 seconds, it is turned off, and if Ci is detected for 9 seconds, a closed loop of the line 17 is formed (line acquisition) and then the process proceeds to step S5. Above, from step S1 to step S4
If the handset is picked up during the period, Ci will be cut off, and you will be able to talk as a normal telephone without proceeding to the following steps.

If the personal identification number is set to "00" in step S5, the message function (automatic voice response) is not executed and the process proceeds to step S81 to proceed to reception of facsimiles. If the personal identification number is other than "00". Ch1 at step S6
It is determined whether or not a voice message is recorded (stored) in (one of a plurality of voice data areas of DRAM8), and if the voice message is recorded, step S6−
Wait 0.5 seconds at 1, then play and send out the voice message data of Ch1 at step S7, then proceed to step S8-1 to set Ch1
If no voice message is stored in, use step S8
After waiting for 0.5 second, the process proceeds to step S8-1. The Ch1 voice message here can be freely set (recorded) by the operator, and is a message that responds to a call from the other party. It is 0 in step S8.
Waiting for 5 seconds means that it is difficult to hear when the voice is sent at the same time when the line is connected, and the line is 0.5% in step S8 in order to avoid voice output during the unstable period immediately after the closed loop is formed. Waiting for a second time.

In step S8-1, the voice message stored in the time-determined area of ROM2 or DRAM8 (voice message indicating that the fax has a fax function, for example, "the fax has a fax function") is played and sent to the line 17. . With this, it is possible to inform the other party that it has the facsimile function.

When the process proceeds from step S8-1 to step S9, a sound for prompting the other side to send a tone dial signal, for example, a beep sound is transmitted, and then at step S10, DTMF from the other side such as D / T / M / F detection is transmitted. Execute a subroutine to identify,
By executing this DTMF detection routine, the personal identification number is input from the other party, and a predetermined flag for selecting various modes of the apparatus is set. When the predetermined flag is set, the subroutine is exited and step S1
Go to 1. In step S11, the personal identification number flag set when the personal identification number is correct from the opponent in step S10 =
Whether it is 1 or not is determined, and if the secret code flag = 1, the process proceeds to step S14 (FIG. 4), and if not, the process proceeds to step S12. In step S12, it is checked whether or not the *** flag = 1 set when the opponent side presses the "*" key provided on the normal dial key three times in succession, If 1, go to step S32 (FIG. 5). Also, in step S13, it is checked whether the other party has made a mistake operation, waits for a facsimile procedure signal from the other party for a predetermined time, and turns OFF if the procedure signal is not received within the predetermined time.
To do.

If you proceed from step S11 to step S14, step S14
Check if the voice message is stored in Ch2 of the non-volatile RAM4. If the voice message is stored,
Play the Ch2 voice message and send it to the line. If no voice message is stored, in step S15 wait for 0.5 seconds as in step S8. Step S17
In step S, a beep sound is sent to prompt sending of DTMF, and step S
Subroutine D for detecting the DTMF of the other party in 18.
Proceed to TMF. At step S19, at step S18, the ** flag indicating that the ** when the operator on the other side presses the "*" key twice in succession is detected is determined and this is 1
If so, the process proceeds to step S24 (FIG. 6), and if the ** flag is not 1, the step S20 discriminates the miss operation flag indicating whether or not it is the miss operation. If the miss operation flag is 1, the line is disconnected. If the miss operation flag is not 1, the process proceeds to step S21. In step S21, it is determined whether or not the Ch2 voice message has been played three times. If the Ch2 voice message has been played three times, the line is opened. If the Ch2 voice message has not been played three times, the process proceeds to step S22. In step S22, it is determined again whether or not the voice message is stored in Ch2. If Ch2 is empty, the line is released. If the voice message is stored in Ch2, the voice message of Ch2 is played, and the process returns to step S17. .

On the other hand, if it is determined in step S19 that ** flag = 1 and the processing proceeds to step S24 (Fig. 6), a sound for prompting the start of recording, for example, a po sound is transmitted in step S24, and a voice message from the line 17 (step S25) is sent. Or, record the voice message from the microphone provided on the device) on Ch2. Then, when the recording of the voice message for a predetermined time (for example, 8 to 16 seconds) is completed in step S25, Ch2 is automatically sent to confirm the content recorded in step S27 after sending a beep sound indicating the end of recording in step S26. Play it back, and send a beeping sound that prompts DTMF to the other party at step S28. Step S29 at Ch
It is judged whether or not the recording operation has been performed 3 times in 2 and the line is opened if it has been performed 3 times.
Enter the routine for detecting. And at step S31 **
Is detected. If the ** flag is discriminated, if 1 is returned to step S24, the line is disconnected if not 1.
As a result, the operator on the other side can redo the recording up to a total of three times by pressing the "*" key twice in succession.

On the other hand, if it is determined in step S12 that the *** flag = 1, and the process proceeds to step S32 (FIG. 5), then in step S32, a ping sound for notifying recording start is transmitted. Then, in step S33, the voice message from the line 17 or the microphone provided in the device is recorded in Ch1. Then, in step S34, a beep sound indicating the end of recording is transmitted, and in step S35
In order to confirm the voice message recorded in step 1, Ch1 is automatically played back, and in step S36 a beep sound is sent to prompt the sending of DTMF. Next, in step S37, it is judged whether or not the recording operation to Ch1 has been performed three times, and after the recording operation is performed three times, the line is opened. Execute the DTMF detection routine to detect DTMF sent from the other party. Then, in step S39, the *** flag indicating that the "*" key has been detected three times in a row is detected again, and if the *** flag = 1, the process returns to step S32, otherwise the line is connected. Refuse. This allows the operator on the other side to re-record up to three times by pressing the "*" key three times in succession. Next, the DTMF detection subroutine used for DTMF detection will be described with reference to FIG. Here, it is assumed that "11" is set in the rotary push switch for inputting the personal identification number.

At step S40, the 5-second timer of the soft timer of CPU1 is set. The DTMF detector 9 shown in FIG. 1 detects the DTMF from the other party, and in step S41, it is determined whether the DTMF signal indicates 1 (whether the tone dial signal is a tone signal indicating 1), and the 1 If it is a tone signal, the process proceeds to step S47, and if it is not 1, the process proceeds to step S42. Next, in step S42, the tone dial signal of the "*" key *
Is sent, and if *, go to step S47,
Otherwise, go to step S43, go to step S43,
In step S43, it is determined whether or not the DTMF other than the "1" key or the "*" key on the partner side is transmitted. If a tone signal other than 1 or * is detected in step S43, the operation proceeds to step S46, the miss operation flag is set to 1, and the operation proceeds to step S47 to set the timer for 5 seconds again. If it is not sent, it is determined in step S44 whether or not the 5-second timer is over. If the time is over, the time-over flag is set to 1 in step S45 and the process returns. If the time is not over at step S44, step S44-
In step 1, it is determined whether or not the other party has received a calling tone signal (CNG) indicating that it desires facsimile transmission. The modem procedure signal such as the CNG signal is detected by the modem unit 18 via the NCU 16. And step S44
If the CNG is received at -1, the process proceeds to step S83 in FIG. 1, and if the CNG is not received, the process returns to step S41.

Also, in step S47, the 5-second timer is set and in step S48.
If it goes to step S48, it is judged whether or not the miss operation flag is "1". If it is 1, the process goes to step S51. If the miss operation flag is not 1, the step is skipped.
In S49, it is judged whether 1 is sent after 1 or not, that is, 11 is sent.
Proceed to S55 and set the 5-second timer again. If other than 11, proceed from step 49 to step 50, and at step S50 *
If it is sent out as *, the process proceeds to step S55 if it is **, otherwise proceeds to step S51. In step S51, it is judged whether or not a value other than 11 or ** is detected, and if there is a value other than 11 or **, the miss operation flag is set in step S54 and the operation proceeds to step S55. In step S52, if the second digit DTMF cannot be detected and the 5-second timer expires, a time-over flag is set in RETURN in step S53. If the time is not over at step S52, the process proceeds to step S52-1, and step S44-1
Similarly, determine whether a CNG has been received. If a CNG is received, proceed to step S83. If a CNG is not received, proceed to step S83.
Return to S48. In step S55, the 5-second timer is reset and the process proceeds to step S56 (FIG. 8). If the miss operation flag is 1 in step S56, the process proceeds to step S59, otherwise the process proceeds to step S57. And step S
If it is determined at 57 that the tone signal of the # key has been detected after 11 is detected, the personal identification number flag indicating that the personal identification number has been confirmed is set at step S63, and a RETURN is performed. If it is not 11 # at step S57, proceed to step S58 and proceed to step S58.
In S58, it is judged whether * after *** is detected, that is, *** is detected three times in a row. If *** is detected, in step S64 the *** flag is set to 1 and RETURN is set.
If it is not ***, it is judged whether 11 # or other than *** is detected in step S59, and if it is detected, step S6
At 2, set the miss operation flag to 1 and return. If the third digit cannot be detected, 5 in step S60
It is determined whether the second timer is over, and if the time is over, the time-over flag is set to 1 in step S61. At this time, if only two consecutive ** are detected, the ** flag is set to 1, and then the process returns. If the time is not over, the process proceeds to step S60-1. Then, in step S60-1, if there is CNG reception as in step S44-1, the process proceeds to step S83, and if there is no CNG reception, step S56.
Return to.

On the other hand, when the process proceeds from step S5 to step S8 to perform facsimile reception, the called station identification signal (CED) indicating that the terminal is a non-voice terminal (indicating facsimile) is transmitted to the modem section 18 and the line in step S81. Control part 1
0, send to line 17 via NCU 16 and proceed to step S83. Then, in step S83, the digital identification signal (DIS), which is the information of the own device such as the receiving function of the own device, is transmitted.
In 84, the other side detects whether it has received a digital command signal (DCS) for determining the mode of communication based on DIS, and sets it to the detected mode of DCS and communicates in the setting mode of DCS. It is detected whether a training check signal (TCF signal) for checking has been received, and when reception of DCS and TCF is completed, the process proceeds to step S85. If there is no signal for a predetermined time at step S84 or if the reception of DCS and TCF is not completed within the predetermined time, it is judged as an error and the line is opened and ended (error end).

When the reception of DCS and TCF is completed in step S84 and the process proceeds to step S85, the reception preparation confirmation signal (CFR signal) indicating that the preparation for reception is completed is sent out, and then in step S86 and S87, the image signal or facsimile communication procedure It is determined whether or not a procedure signal (in this case, EOP indicating the end of the procedure, EOM indicating the end of the message, MPS indicating the presence of the next page, etc.) is received. When it is determined in step S86 that the image signal has been received, the received image signal is demodulated by the modem section 18 in step S88, then decoded and output to the recording section 6 as binary image data for recording.
When the image signal of one page is received and recorded in this way, when the procedure signal of the facsimile communication procedure is received and detected in step S87, the procedure signal is discriminated in steps S89, S91, S93, S99, and the multi-page signal (step S89 When it is determined that the MPS signal has been received, a message confirmation signal (MCF signal) is sent in step S90, and then the process returns to step S86 to receive and record the image signal of the next page. When it is determined in step S91 that the message end signal (EOM) is received, the MCF signal is transmitted in step S92, and then the process returns to step S83 to perform the pre-procedure of the facsimile communication procedure.

If it is determined in step S93 that the procedure end signal (EOP) has been received, the MCF signal is sent in step S94, and then step S95.
When the line disconnection signal (DCN signal) is received and detected within a predetermined time and the DCN signal is detected within a predetermined time, the line 17 is opened in step S96 and the process proceeds to step S97.

When it is determined in step S99 that the call request signal has been received, the operator is called by the speaker 15 and the call mode is entered.

When the process proceeds to step S97, it is determined whether the reception of the fax signal is continued from the recording of the voice message to Ch2. If it is determined that the reception of the fax signal is performed after the recording of the voice message, the nonvolatile data is received in step S98. “Voice message available” stored in RAM4
Image data such as is read out and printed out at the end of the recording paper on which the received image is recorded. This allows the operator at the other end to record the voice message relating to the image data to be transmitted to the DRAM8 and then transmit the image at a time, so that the voice message can be added to the image and the voice can be added to the recording paper on which the image is recorded. Since the information indicating that there is a message is additionally recorded, the operator on the receiving side can easily know that the received image has a voice message.

In addition, the step built-in speaker
Since the signal from the line from S1 to S10 is output as sound, you can monitor the voice from the other party without turning off the handset.

As a result, when a person who does not understand the specifications of this unit comes from outside, and if there is a person near the unit by monitoring the sound, take the handset 11 shown in Fig. 1. By pressing the stop button shown on the keyboard in FIG. 2 and canceling the message function on the way, it is possible to talk with the other party like a normal telephone.

Next, a case of recording from a microphone and reproducing from a speaker using this unit will be described with reference to FIG. Step S6
In step 5, it is judged whether the personal identification number is set to "00", and if it is "00", it is turned off. If it is other than "00", it is determined in step S66 whether the message key 22 shown in the keyboard of FIG. 2 is pressed. If it is pressed, step S67 is pressed. If it is not pressed, step S72 is pressed.
Proceed to. In step S67, it is determined whether the hold key 23 is pressed, that is, whether the message key 22 and the hold key 23 are pressed at the same time. If they are pressed, the process proceeds to step S68, and if they are not pressed, the process proceeds to step S75.
In step S72, it is determined whether or not the hold key 23 is pressed, and if it is pressed, the process proceeds to step S73, and if it is not pressed, the process proceeds to OFF. In step S73, it is determined whether or not the message key 22 is pressed, that is, it is determined whether or not the hold key 23 and the message key 22 are simultaneously pressed as in step S67, and if they are pressed, the process proceeds to step S68.
If it has not been pressed, the process proceeds to hold. In step S68, a po-ring sound prompting the start of recording is sent from the speaker, and in step S69, the slide switch 24 of the keyboard shown in FIG. 2 judges whether the standard is fine or not.
Record Ch1 with S70, and if it is a tune, step S74
To record Ch2. At step S71, a beep sound is sent to notify the end of recording and turned off.

If only the message key 22 is pressed in step S67, the process proceeds to step S75, and in step S75 of FIG. 10, it is determined whether the slide switch 24 is the standard fine. If standard, proceed to step S76, and if fine, proceed to step S79. In step S79, it is determined whether or not there is content in Ch2, and if empty, the process proceeds to step S78. If there is any content, play Ch2 in step S80, and proceed to step S78. If it is standard, in Step S76, it is judged whether or not there is content in Ch1, and if it is empty, it goes to Step S78, and if there is content, it plays Ch1 in Step S77 and goes to Step S78, where playback / end or Ch1 or Ch2 is empty. In case of, it sends out a beeping sound indicating that it is empty and proceeds to OFF.

As described above, in this embodiment, automatic voice response and facsimile automatic reception can be performed by setting the automatic reception. At this time, if the automatic voice response mode is selected, the voice message recorded in Ch1 of DRAM8 will be sent out.However, even in the automatic voice response mode, when the procedure signal is received after sending the voice message, the prompt message is automatically sent. Can receive. Further, even if the automatic reception mode is set, the voice from the other party can be monitored, so that the operator can talk by stopping the automatic voice response before shifting to facsimile reception.

If the automatic facsimile reception mode is set, the facsimile reception starts immediately.

That is, in the present embodiment, it is possible to set whether to prioritize voice communication or facsimile communication. By selecting the automatic voice response mode, this device can be mainly used for communication, and the automatic facsimile reception is also possible. Further, if the automatic voice response mode is set, it takes time to perform facsimile reception. Therefore, when this apparatus is mainly used for facsimile communication, the facsimile automatic reception mode may be set.

Further, in this embodiment, it is a voice message at the time of voice response.
The voice message of Ch1 can be freely rewritten by inputting the PIN code from the telephone of the destination by the tone dial signal, so for example, the voice message "I am currently going to XX." Is "I am currently going to XX." It can be rewritten as a voice message ".

Further, in the present embodiment, when the sound signal is sent to the other party, the sound signal is sent immediately after the line is seized rather than immediately after seizing the line, so that the operator on the other side can surely hear the sound signal. Can be done.

Further, in the present embodiment, when the voice message is recorded from the outside, the recorded message is automatically reproduced, so that it is possible to easily confirm whether or not the voice message can be reliably recorded. 3 audio message recordings
You can start over.
