BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device with an answering machine (an answering machine recording function) incorporated in a telephone or a facsimile machine.

[0002]

2. Description of the Related Art A telephone having an answering machine capable of recording a telephone call of an incoming call in the absence of a telephone, that is, an answering machine (TAD: Terephone Answering).
Device) is OGM (Out
An announcement signal called Going Message)
For example, after sending a voice signal to the line saying "I am out of office right now. If you are in need, please speak your message after a beeping sound", switch to recording mode and record the call contents from the other party. It is supposed to do.

The recorded contents can be played back and listened to from an external telephone by remote operation. In remote playback, the recorded contents that are no longer needed can be deleted. A magnetic tape, an IC or the like is used for recording. When an electronic storage means such as an IC is used, the cost for storage capacity is higher than that of a magnetic tape. Therefore, when erased, it is desirable that the erased area can be used for the next recording. for that reason,
Garbage processing is performed so that deleted recordings are deleted, the inside of the memory is organized, and the deleted areas can be used.

The garbage processing is performed every time the data is erased, but the garbage processing requires time, for example, about 30 seconds. Since the operation cannot be performed during the garbage processing, there is a particular problem in enabling the erasing by the remote function. However, from the viewpoint of effective use of memory, it is desirable to be able to perform garbage processing even in the remote operation mode. It is possible to provide a remote operation command for garbage, but if the operation is forgotten, it will be meaningless even if the deletion is performed.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and in a voice communication device with an answering machine function, a voice communication device with an answering machine function that can perform garbage processing without affecting the operation. It is intended to provide.

By pressing the delete button for a predetermined time, for example, 3 seconds during standby, all of conversation recording, memo recording, and message recording can be deleted.

Regarding the reception mode, three types of settings are possible. It is a manual reception mode, a FAX / TEL automatic switching mode, and an answering machine / FAX automatic switching mode.

The first reception mode is a manual reception mode. In this mode, the incoming call is only through the TEL section, and the bell continues to ring until the auxiliary telephone or sub telephone is off-hooked. Since there is no switching to the FAX section, there is no incoming call at the FAX section. When the picked-up telephone is a facsimile machine or when switching to a facsimile machine during a conversation, by pressing the start / copy button in the off-hook state, the facsimile can be transmitted or received.

The second reception mode is the FAX / TEL automatic switching mode. In this mode, the bell sound is cut to allow incoming calls. FIG. 7 is an explanatory diagram of the lapse of time in the FAX / TEL automatic switching mode. The numbers in the figure show the time in seconds,
This value is an example, and the value is not limited to this.
This will be described with reference to FIGS. 1 to 3.

When there is an incoming call, a 16 Hz DC intermittent signal is received as a bell sound from the line and is detected by the incoming call detection circuit 54. In the standby state, the changeover switch 49 is
Since it is connected to the contact on the side opposite to the figure, there is no ringing of the bell sound in the auxiliary telephone and the sub telephone. When the bell sound is detected a fixed number of times, for example, twice, the line controller switches the changeover switch 48 to the modem side to close the DC circuit of the line. This stops the ringing sound from the line and receives the signal from the line.

Next, in order to notify the calling side that the call is in progress, a pseudo ringback tone is sent to the line control unit 2.
To line 1. In this embodiment, the pseudo ringback tone is a signal of 1 second transmission and 2 second interruption, which has the same pattern as the bell sound. At the same time, CNG is detected during the disconnection period. At the same time, the off-hook of the auxiliary telephone and the slave telephone is monitored. When the CNG detection and the pseudo ring back tone are transmitted four times, a pseudo bell sound is generated from the buzzer 39 in parallel with this to notify the incoming call of the telephone. If CNG is detected during the above-described four times, the process shifts to facsimile reception. In this case, facsimile reception can be performed without ringing.

The pseudo bell sound is generated when the pseudo ring back tone is stopped and sounds for 1 second. Therefore, 2 seconds is off. In this embodiment, the pseudo bell sound is set to 9 times, and if CNG is detected during this time, the process shifts to the reception of a facsimile signal, and if the handset of the auxiliary telephone or the slave telephone is taken up, the changeover switches 48 and 49 are taken.
Is switched to the position shown in the figure, and the call is started. If the picked up phone is a facsimile, press the Start / Copy button manually or dial a specific number to dial and transfer to the FAX section.

In this embodiment, the CNG detector (not shown) detects the CNG periodically during the period in which the pseudo ringback tone is generated. That is, in the period in which the pseudo ringback tone is off, CNG
The detector detects CNG. CNG is
In this embodiment, the pseudo ringback tone is 1 second transmission and 2 seconds interruption, while 0.5 seconds transmission and 3 seconds interruption are repeated. Therefore, the CNG transmission period of 0.5 seconds is detected. Even if the pseudo ring back tone, which is the period, is off from the disconnection time, the detection period is always met in a few cycles, and CN
G can be detected. If CNG is detected, it is determined that the incoming call is from a facsimile, and the CPU
20 immediately stops the generation of the pseudo ringback tone and the pseudo bell sound and jumps to the CED / DIS transmission procedure. If there is a DCS response from the calling side, the facsimile reception procedure can be entered. If the DCS cannot be received, the line disconnection command DCN is sent to disconnect the line when about 40 seconds have passed.

When the incoming call is a telephone call, CNG is not detected, and thus the pseudo bell sound is repeated. In this process, when the operator answers and picks up the handset of the auxiliary or sub-phone, off-hook is detected,
The line controller connects the off-hook handset to the line to enable a call with the calling side. Generation of pseudo ringback tones and pseudo bell sounds is stopped. Pseudo bell sound is 9
If the auxiliary telephone or the slave telephone is not off-hook during the time, the procedure proceeds to the facsimile reception procedure.

The response message 2 may be transmitted when the number of occurrences of the pseudo ringback tone reaches the set number 9 due to the absence of the operator. Response message 2 is for sending out when the recording memory is used up. "Yes, this is ○○. I'm out now. Please press the send button. " The caller hears this and knows that he / she is out. Therefore, by hanging up the call, it is possible to prevent further charges.

When the response message 2 is transmitted, the facsimile reception mode is set thereafter.
When the calling side is a manually transmitted facsimile, after the second message is heard, C is subsequently sent to the calling side.
All you have to do is press the send button when you hear the ED followed by a beeping DIS. As a result, the facsimile from the calling side can be received.

If no facsimile signal is transmitted from the calling side, DIS transmission is repeated, and when about 40 seconds have elapsed from the start of CED transmission, a line disconnection command DCN is transmitted to disconnect the line.

In this embodiment, CNG monitoring is
This was done during the period when the pseudo ringback tone was cut off. Therefore, when the CNG is monitored, the pseudo ringback tone is not transmitted to the line, so that the CNG can be detected without being affected by the harmonics of the pseudo ringback tone. CNG may be detected even during transmission of the pseudo ringback tone by using a determination unit that is less likely to be affected by harmonics of the pseudo ringback tone.

FIG. 8 is a flow chart for explaining the FAX / TEL automatic switching mode described in FIG.
The flow starts with an incoming call. Cut the bell sound and make a non-call incoming call. In step S101, the bell sound is received twice to close the DC circuit of the line, and in step S102, CNG from the calling side is detected. If CNG is not detected within 2 seconds, the process proceeds from S103 to S104, and a pseudo ringback tone is transmitted. One second later, the pseudo ringback tone is turned off, and the process loops from S106 to S102 to repeat CNG detection and pseudo ringback tone transmission. If CNG is detected, S102 to S116
Shift to S1 and CED and DIS are sent in S116, and S1
Moving to 18, the facsimile reception procedure is performed. Therefore, if the CNG is detected at this stage, it is possible to shift to the reception of the facsimile without sounding.

If CNG cannot be detected within the set number of pseudo ringback tones, for example, four times, S105.
From S107 to S107, a pseudo bell sound is generated to ring the attached telephone and the slave telephone to notify the incoming call. At the same time, S108 to S112 are looped to repeat CNG detection and pseudo ringback tone transmission. If CNG is detected, the process proceeds from S108 to S115, the pseudo bell sound is stopped, CED and DIS are sent out in S116, and the process proceeds to S118 to carry out the facsimile reception procedure. Set the number of times the pseudo bell sound is set, for example, CNG within 9 times.
Even if cannot be detected, the process proceeds from S111 to S115, the pseudo bell sound is stopped, and CED and DIS are performed in S116.
Is sent, and the process proceeds to S118, and the facsimile reception procedure is performed.

If the attached telephone or the slave telephone is off-hook during the loop of repeating the detection of CNG and the transmission of the pseudo ringback tone in S102 to S106, the process proceeds from S106 to S114 to switch the line to the telephone side. The call is made. S108 to S112
If the attached telephone or the slave telephone is off-hook during the loop of repeating the detection of CNG and the transmission of the pseudo ringback tone while sounding the pseudo bell sound in S11, S11
2 to S113, stop the pseudo bell sound, S1
At 14, the line is switched to the telephone side and a call is made. If the caller requests to send a fax during a call, you can press the Start / Copy button manually or dial a specific number to fax.
It is possible to transfer to another unit and switch to the facsimile reception mode for reception.

The third reception mode is an answering machine / FAX automatic switching mode. This mode is an answering machine setting,
The call is recorded in the TAD section, and when a facsimile is received, the procedure shifts to a facsimile reception procedure. Figure 9
[Fig. 6] is an explanatory view of a time course in an answering machine / FAX automatic switching mode. The times in the figure are examples, and the present invention is not limited to these. This will be described with reference to FIGS. 1 to 3.

When there is an incoming call, a DC intermittent signal of 16 Hz is received as a bell sound from the line and is detected by the incoming call detection circuit 54. Since the changeover switch 49 is connected to the position shown in the figure, the bell sound is emitted from the auxiliary telephone and the slave telephone. The bell sound is detected by the CPU 20 through the incoming call detection circuit 54 and recognized by the FAX unit. A certain number of times, 2 in this example
When the ringing sound is detected, the CPU 20 issues an incoming call command to the TAD section, and the TAD section closes the DC circuit of the line. This stops the bell sound and receives a signal from the line.
If there is no message recording, memo recording, or conversation recording, the TAD section receives the call with five bell sounds.

Next, the TAD section sends the response message 1 to the line. Reply message 1 can be up to 16 seconds, for example, "Yes, this is XX. I am out of the office so I can accept this message with this answering machine. The beeping sound has ended. If so, please tell us your name, telephone number, and requirements. Also, since you can receive a fax, if you are a fax, please press the send button. " Response message 1
After that, a signal sound for shifting to the recording state of "Pee" is sent out, and the message recording state is entered. The time for recording a message is one, which is a maximum of 5 minutes. The recording time of the entire ICM is, for example, about 10 to 20 minutes.

Upon reception of the incoming call, the CPU 20 monitors off-hook of the attached telephone and the sub-phone, and if off-hook, the sending or recording of the response message 1 is finished and the call can be made. The speaker 12 is turned on at the same time as the incoming call, and the response message 1 and the call for the message are emitted.

Upon entering the message recording, if a silent state of 6 seconds is detected within 70 seconds, the facsimile reception procedure is started. If, after 70 seconds have elapsed, the continuation of the silent state for 6 seconds is detected, the recording is terminated and the line is disconnected.
If CNG is detected twice during recording, the recording is terminated and the procedure proceeds to the facsimile reception procedure. If CNG is detected within 10 seconds from the start of recording, the recorded content is
It erases from M and shifts to the facsimile reception procedure. If a busy tone is detected during recording or a momentary disconnection of the line (a momentary disconnection occurs when the caller disconnects the line), recording is terminated and the line is disconnected. To do.

FIG. 10 shows the recorded message / fax described in FIG.
It is a flow chart for explaining automatic change mode. This mode is set by pressing the answering machine button 92. As a result, the TAD unit and the FAX unit perform handshaking for transmitting and receiving commands and data. As an example, the TAD section sends an absence setting command (1 byte), ICM remaining recording time data (2 bytes), various information, and message count data (1 byte) to the FAX section.
In response to this, the FAX unit turns on the LED for answering machine setting and changes the display on the LCD. This state is the standby state, and the flow starts when an incoming call arrives. 16 from the line
The DC intermittent signal of Hz is received as a bell sound and is detected by the incoming call detection circuit 54. As described above, the CPU 20 of the FAX unit sends the incoming command and the secret code (4 bytes) to the TAD unit by the bell sound 2 or 5 times, and the TAD unit closes the DC circuit of the line in S121. . The personal identification number is the personal identification number sent at the time of remote reception.

Next, in S122, the TAD section sends the response message 1 to the line. Further, the TAD unit sends a command requesting clock data to the FAX unit, and S123
Then, the TAD unit reads the clock data (1 byte for each month and date) sent together with the clock data command sent from the FAX unit. As a result, the TAD unit sends a signal sound "Pee" to the line, and enters the message recording state in S124. In step S125, the FAX unit starts CNG detection, and simultaneously starts silence detection. In addition, a timer that sets the recording start time to 0 is activated, and the process enters a loop from S126 to S131.

If CNG is detected, the FAX section starts TA
D The command to end the recording is sent to the TAD unit, the process proceeds from S126 to S132, and if it is within 10 seconds from the start of the recording, the possibility of ending the recording in S133 and including the call is extremely small. Since it is considered that only the facsimile reception is performed, the recorded contents are erased and the facsimile reception procedure of S135 is performed. In S132, 1
If it exceeds 0 seconds, it is considered to be a facsimile of manual transmission, and the recording is ended in S134, and the facsimile receiving procedure of S135 is performed. When the facsimile reception is completed,
The line is disconnected, and the FAX section sends a command for requesting the absence setting to the TAD section. In response to this, the TAD unit sends the remaining time data, various information, and the message number data to the FAX unit following the answer setting command, and enters the standby state of S141.

In the silence detection of S127, the FAX unit monitors the case where the silence state continues for 6 seconds. When the silence is detected, the FAX unit issues a TAD recording end command to the TAD
Then, the process proceeds to S136 to end the recording. If the silent state is reached within 70 seconds from the start of recording, manual transmission of a facsimile is considered, so the facsimile reception procedure is performed in S138. If it exceeds 70 seconds, S1
41 becomes the standby state.

When a command is received from the TAD section,
The process proceeds from S128 to S139, command processing is performed, and the process returns to the loop.

When the FAX unit detects the on-hook of the TAD to detect the disconnection of the line, the process proceeds from S130 to S140, the recording is ended, and the FAX unit sends a command for the absence setting request to the TAD unit. In response to this, the TAD section
Following the command for setting the absence, the remaining time data, various information, and the message number data are sent to the FAX unit, and the standby state of S141 is entered.

The same is true when a momentary interruption is detected in the FAX section, and a TAD recording end command is sent to the TAD section.
After shifting from S129 to S140, the TAD section finishes the recording, and after the line is disconnected, the FAX section sends a command for the absence setting request to the TAD section. In response to this, the TAD unit sends the remaining time data, various information, and the message number data to the FAX unit following the answer setting command, and enters the standby state of S141.

If the slave telephone is off-hook, S1
After shifting from 31 to S140 and ending the recording and ending the call on the slave telephone, the standby state of S141 is entered.

The flow of the ICM recording start operation in the TAD section will be described with reference to FIG. In response to the incoming call, in S150, as described in FIG. 10, the FAX unit sends the incoming command and the stored personal identification number to the TAD unit. In S151, the TAD unit closes the DC circuit of the line and receives the call. ICM
If the remaining time is less than 8 seconds, the recording time is too short, so the process proceeds from S152 to S158.
If not, the system is ready for recording. First, S153
Then, the response message 1 (OGM
1) is transmitted, the TAD unit sends a command requesting clock data to the FAX unit in S154, and the TA unit in TA in S155.
The D section takes in the clock data sent together with the clock data command from the FAX section. As a result, the TAD section
A signal sound "pee" is sent to the line, and in S157, a message recording state is entered. When recording started, CNG was detected,
The start of silence detection and the like is as described above. If "#" requesting remote operation is received before entering the recording state, the process proceeds from S156 to remote operation to be described later.

When pager transfer is set, a transfer request command is sent from the FAX unit to the TAD unit after recording is completed. After 10 seconds, the TAD goes off-hook, and in this embodiment, the telephone number stored in the shortened number 19 is read out and dialing is performed. After that, a transfer tone is sent, and after 40 seconds, the line is disconnected and the line is disconnected. The FAX unit detects the on-hook of the TAD, and accordingly sends the command of the absence setting request to the TAD unit. In response to this, the TAD unit sends the remaining time data, various information, and the message number data to the FAX unit following the answer setting command, and enters the standby state.

When the remaining time of the ICM is 8 seconds or less in S152, the process proceeds to S158, the response message 2 (OGM2) having the above-mentioned content is transmitted, and S15
At 9, the TAD unit sends a command requesting clock data to F
The data is sent to the AX unit, and in S160, the TAD unit takes in the clock data sent together with the clock data command sent from the FAX unit. Then, in order to monitor facsimile reception, a timer of 10 seconds is started in S161. When 10 seconds have passed or when a busy tone is detected, the line is disconnected from S162 or S163. The FAX unit detects the on-hook of TAD,
As a result, the command for the answer setting request is sent to the TAD unit. In response to this, the TAD section follows the command for setting the absence, and displays the remaining time data, various information, and the message number data in the F
It is sent to the AX section and put in a standby state.

During this time, "#" for requesting remote operation
Is received, the process proceeds from S164 to a remote operation described later.

12 and 13 are flow charts for explaining an example of remote operation. As described above, when “#” is received after the incoming call, the mode is changed to the remote operation mode. If OGM1 is being sent, S170
Stop sending. As will be described later, although the personal identification number is subsequently sent, the remote operation mode is entered regardless of whether the personal identification number is correct, and in step S171, the TAD unit sends a remote operation command to the FAX unit. As a result, the CNG detection and the silence detection on the FAX side are stopped, and are not performed thereafter. Then, the process goes to the loop of S172 to S175 to wait for the personal identification number. If the attached phone or sub-phone is off-hook during this time, the loop is exited in S172,
The call is made. If "#" is received in S174 after the DTMF of the personal identification number in S173, the personal identification number sent from the FAX unit at the time of the incoming call is compared with the received personal identification number in S176, and if they do not match. Is S17
In step 7, an error sound is sent to the line, the process returns from step S178 to step S172, and waits for the reception of the personal identification number again. If the received personal identification numbers do not match three times, the process proceeds to S179, the TAD side on-hooks, and the line is disconnected.

In S176, if the result of the comparison between the personal identification number sent from the FAX unit at the time of the incoming call and the received personal identification number is the same, the process proceeds to A in FIG.

In FIG. 13, the personal identification number is further checked. If the received personal identification number is "0000", the remote operation is not entered.
The personal identification number is set and registered by the user of the device, but an appropriate personal identification number is registered by default.
In this example, it is “0000”. If the user forgets to register the password for the first time, or forgets to re-register when there is a power failure due to exhaustion of the backup battery, the password is "0000".
In this state, the third party has an initial setting number of “000”.
Sending "0" causes remote operation.
Therefore, in S190, it is checked whether it is the initial setting number. If it is the initial setting number, an error sound is emitted in S191, B is entered into B of FIG. 12, and S17 is entered.
The process shifts to 9 and the TAD side goes on-hook to disconnect the line. Therefore, remote operation cannot be performed with the initial setting number.

Returning to FIG. 13, in S190, if the received personal identification number is not the initial setting number, first, the recorded contents of the ICM are transmitted to the calling side. After a short confirmation beep sound is sent out in S192, if there is a memo recording, a beep sound for 1 second is sent out in S194. If there is no memo recording, S
Pass 194. Next, the number of message recordings is sent, but each time recording is performed, the recording start time and the first is 1, and the number that is incremented at the time of sequential recording is stored in the memory for each message recording. Has been done. Explaining the number of message recordings as m, S196 to S202 are a flow of transmitting the number of message recordings. That is, if m is 10 or more, the number n of beeps is set to 10, and if m or less,
Let m be the number of beeps. Each time j is incremented from 1, a short beep is emitted in S200. S20
In 1, j = n, that is, n beep sounds are transmitted, and the process proceeds to S203. Therefore, the calling party can know the number of message recordings by counting the number of short beeps. If there is no message recording, the process proceeds from S195 to S203.

The loop from S203 to S210 is a flow for receiving a command for remote operation. In this embodiment, there are the following six types of remote operation commands. 0 # ...... Absent setting cancellation 1 # ...... Room monitor 40 # ...... Playback 42 # ...... Erase all 60 # ...... Transfer set 61 # ...... Transfer cancellation In addition, the following operations are possible during remote playback. . 40 # ...... Playback end 41 # ...... Erase 44 # ...... Pause 45 # ...... Repeat 46 # ...... Skip Further, during room monitoring, the monitor operation can be ended by "1 #".

The meaning of these commands is, for example, after the caller sends "40" with a push button,
This means that when "#" is transmitted, the command "40 #" is transmitted and the recorded content is reproduced. However, these command numbers can be set appropriately, and other commands can be discarded. For example, it is possible to notify the reception state of the facsimile by a beep sound, or to perform pager transfer and set / cancel the setting remotely. Further, it is also possible to set memory reception as a facsimile reception mode, or to set / cancel this remotely. If the memory reception is used, the received contents can be polled from an external facsimile device.

Although the illustration of "0 #" is omitted in the flow of FIG. 13, "0 #" is included in the loop of S203 to S210.
When the message is received, the in-home setting is stored in the mode setting state memory of the FAX unit. In the present embodiment, in the manual reception mode, in order to perform the answering machine setting from the external telephone, in this embodiment, the answering machine setting request command is sent from the FAX section to the TAD section when the bell sound is received, for example, 20 times. You can now set the answering machine / FAX automatic switching mode. By the two-step operation of enabling the absence setting when the first predetermined number of bell sounds are received and the second predetermined number of bell sounds are received within a predetermined time after disconnection of the line. By transmitting the setting command in the reception mode, it is possible to reduce the probability that the mode is set in an accidental state.

The remote operation mode will be described. S
If "1 #" is received during the loop from 203 to S210, and if the room is not being monitored, the process proceeds from S203 and S211 to S212 to start the room monitoring and then to S203.
The process returns to the loop of S210. During the room monitor, the room sound can be heard from the external telephone through the microphone 8. When "1 #" is received again, S203, S211 to S2
13, the room monitor is terminated, and S203 to S203
Return to the loop of 210.

When "40 #" is received, S214
Then, the remote reproduction is performed. The remote reproduction will be described later with reference to FIGS. 14 to 17.

[60 #] for setting / releasing pager transfer
Performed at "61 #". In this embodiment, the pager transfer telephone number is registered in the shortened number 19. Therefore, if "60 #" is received and the shortened number 19 is registered, the process proceeds from S206, S216 to S217, a transfer set command is sent from the FAX unit to the TAD unit, and pager transfer is set. You may make it a transfer telephone. When "61 #" is received,
The process proceeds from S207 to S218, and the transfer cancellation command is FA.
It is sent from the X section to the TAD section, and the pager transfer mode is released.

During the loop of S203 to S210, 60
When no operation is performed for a second, when a busy tone is detected, or when the auxiliary telephone or the slave telephone is off-hook, S208, S209, and S208, respectively.
The process moves from 210 to B in FIG. 12, and in S179, the TAD is hooked on. In case of off-hook of S210,
The call is made.

Returning to FIG. 12, when the TAD section is hooked on in S179 and erased during the remote operation, the process proceeds from S180 to S181, the command in the garbage is sent, and the garbage process is performed in S182. When the garbage is completed, the process proceeds from S183 to S184 and S185. In S184 and S185, it is determined whether the memory of the mode setting state in the FAX unit is the absence setting or the home setting, and the absence setting request command or the home setting request command is sent from the FAX unit to the TAD unit. In response to this, if the received command is the answering machine setting, the process proceeds from S186 to S187 to perform the answering machine setting, and sends the answering machine setting command to the FAX section. If the received command is at-home setting, S186 to S1
Proceed to 88 to set at-home setting, and then set the at-home setting command to F.
Send to AX department. Following this, in S189, the remaining time data, various types of information, and the number-of-messages data are sent to the FAX unit, and the standby state is set.

14 to 17 are flowcharts for explaining an example of remote reproduction in S214 of FIG. FIG. 14 is a flow of conversation recording reproduction, FIG. 15 is a flow of memo recording reproduction, FIG. 16 is a flow of message recording reproduction, and FIG. 17 is a flow of ending the remote reproduction mode.

It will be described with reference to FIG. Remote playback is "4
If it is selected in "0 #", it is determined in S220 whether or not there is conversation recording, and if there is conversation recording, reproduction of the recording is started in S221 of FIG. During playback, S222 to S2
Looping 29. When "40 #" is received during the loop of S222 to S229, the remote reproduction is terminated and the process jumps from S222 to E in FIG.

During the loop of S222 to S229, "4
When "1 #" is received, the process proceeds from S223 to S230, the conversation recording being reproduced is erased, and the process proceeds to C in FIG.

During the loop of S222 to S229, "4
4 # ”is received, the process proceeds from S224 to S231, the reproduction is temporarily stopped, and the process from S232 to S234 to S237 is performed.
To loop. When "44 #" is received, the reproduction is restarted in S233, and the process returns to the loop of S222 to S229. If there is no operation for 1 minute during the pause,
It jumps from S237 to E of FIG. If "45 #" is received during the pause, the repeat of the conversation reproduction from the beginning is performed after one second from S234 to S238. When "41 #" is received during the pause, the process proceeds from S235 to S230, the conversation recording is erased, and the process proceeds to C in FIG. When "46 #" is received during the temporary stop, the reproduction of the subsequent conversation recording is skipped from S236 and the process proceeds to C of FIG.

During the loop of S222 to S229, "4
When "5 #" or "46 #" is received, repeat or skip is performed as described above.

When a busy tone is detected during the loop of S222 to S229, or when the auxiliary telephone or the slave telephone is off-hook, S2, respectively.
27, the process proceeds from S228 to C in FIG. In the case of off-hook in S229, a call is made. When the reproduction of the conversation recording is completed, the process proceeds from S229 to C in FIG. Similarly, if there is no conversation recording in S220, the process similarly shifts to C in FIG.

FIG. 15 is a flow of reproducing memo recording. The process shifts from C in FIG. This flow is the same as that in FIG. 14 and can be understood from the description of FIG. 14, so description will be omitted. When there is no memo recording, when the reproduction of the memo recording is completed, or when erasing or skipping is performed, the process moves from D to D in FIG.

FIG. 16 is a flow chart of reproduction of message recording. The process shifts from D in FIG. This flow is also the same as that in FIG. 14, except that the number of message recordings may be two or more. That is, in S280, i is the number m of message recordings.
And the reproduction is started from the i-th item in S282.
Playback is performed in order from the latest recording. The operation during the i-th reproduction is the same as the flow described with reference to FIG. When the i-th playback is completed, S
In step 291, the i is decremented by 1, the preceding message recording is reproduced, and this is repeated. I = 0 when all items have been played back
Therefore, the process proceeds from S281 to E in FIG. If there is no message recorded, or if deletion or skip is performed, the process moves from E to E in FIG.

FIG. 17 is a flow of ending the remote reproduction mode. The process shifts from E in FIGS. 14 to 16. S3
At 10 a beep is sent to the line, at S311 the timer set to 60 seconds is started, and the loop of S312 to S315 is entered. When the timer times out, the standby state starts from S315. If "40 #" is received within 60 seconds,
From S312, the process returns to F in FIG. 14 and remote reproduction can be performed again from the beginning. When "45 #" is received, the process proceeds from S313 to S316, 1 is added to i,
Returning to G in FIG. 16, the reproduction state of the message immediately before the reproduction of the last recorded message is entered. When "42 #" is received, S
The process proceeds from step 314 to step S317, all deletion is performed, and FIG.
The process returns to the loop of S203 to S210 and enters the standby state.

S238, S239, S241 of FIG.
S268, S269, S271 in FIG. 15 and S3 in FIG.
The steps of the 1-second timer of 00, S301 are "40 #", "41 #", "44" before the 1-second timer starts when the step moves to this step and the time is up.
When "#", "45 #", and "46 #" are received, the reproduction end, erase, pause, repeat, and skip operations corresponding to the respective operations are performed, but the illustration of the flow of that portion is omitted. In this case, the 1-second timer is reset when the first digit DTMF is detected, the 1-second timer is restarted to receive the next digit, and the command is checked when the third digit is received. Is "40 #", "41"
If any of “#”, “44 #”, “45 #”, and “46 #” is applied, the operation is performed.
You may make it transfer to the following step of a second timer.
It is possible to make room for sending buttons by remote operation.

Incidentally, "40 #", "41 #", "44"
The command for remote operation is not limited to the above-mentioned examples, and is not limited to “#”, “45 #”, and “46 #”. Of course, the numeral portion may be a single digit. It is preferable that the command is simple in order to perform an operation such as transmitting the command during a short time-up such as the one second timer described above. One-digit numbers and symbols such as "#" may be combined.

18 to 21 are flow charts for explaining an example of the reproduction operation when the reproduction / stop button 93 of FIG. 6 is pressed. FIG. 18 is a flow of reproducing conversation recording, FIG. 19 is a flow of reproducing memo recording, FIG. 20 is a flow of reproducing message recording, and FIG. 21 is a flow of ending reproducing operation.

It will be described with reference to FIG. When the play / stop button is pressed, it is determined in S320 whether or not there is conversation recording, and if there is conversation recording, reproduction of the recording is started in S321 of FIG. During reproduction, S322 to S327 are looped. When the play / stop button is pressed during the loop of S322 to S327, the play operation is ended and S3 is executed.
Jump from 24 to K in FIG.

When the repeat button is pressed during the loop of S322 to S327, the one second timer of S322 to S328 is started, and then the process returns to S321 and repeat operation is performed.

When the skip button is pressed during the loop of S322 to S327, the reproduction of the conversation recording is stopped,
After shifting to H in FIG. 19, the skip operation is performed.

If the delete button is pressed during the loop of S322 to S327, the flow advances from S325 to S329 to delete the conversation recording being reproduced and move to H in FIG.

When the pause button is pressed during the loop of S322 to S327, the process proceeds from S326 to S330, the reproduction is paused, and S331 to S334 are looped. When the repeat button or the skip button is pressed during this loop, the above-described repeat operation or skip operation is performed from S331 or S332.
When the play / stop button is pressed during the loop of S331 to S334, the play operation is stopped and the process jumps to K in FIG. When the pause button is pressed during the loop of S331 to S334, the reproduction is restarted in S233, and S
Return to the loop from 222 to S229.

When the reproduction of the conversation recording is completed, the process proceeds from S327 to S336 to start the 1 second timer. The time shifts from S339 to H in FIG. S32
Similarly, when there is no conversation recording at 0, the process similarly shifts to H in FIG. If the repeat button is pressed before the time is up, the process proceeds from S337 to S328, and repeat operation is performed. If the play / stop button is pressed before the time is up, the play operation is ended and the process jumps to K in FIG.

FIG. 19 is a flow chart of the reproduction operation of memo recording. The process shifts from H in FIG. This flow is shown in FIG.
The description is omitted because it is similar to the above and can be understood from the description of FIG. 18. If there is no memo recording,
When the reproduction of the memo recording is completed, or when the memo recording is erased or skipped, the process proceeds to I in FIG.

When the repeat button is pressed,
The process moves to S369 to start the 1 second timer. When the time is up, the process returns to S341, and the reproduction of the memo recording is repeated. However, if the repeat button is pressed again before the time is up, the process returns to L in FIG. 18 to repeat the reproduction of the conversation recording. If the play / stop button is pressed before the time is up, the play operation is terminated and the process jumps to K in FIG.

FIG. 20 is a flow chart of reproducing the message recording. The process shifts from I in FIG. This flow is also the same as that in FIG. 20, except that the number of message recordings may be two or more. That is, in S360, i is the number m of message recordings.
And the reproduction is started from the i-th item in S362.
Playback is performed in order from the latest recording. The operation during the i-th reproduction is the same as the flow described with reference to FIG. In step S368, the i-th playback is completed, the 1-second timer is started in step S370, and i is decremented by 1 in step S374, and steps S361 to S3 are performed.
Returning to step 62, the previous message recording is reproduced and this is repeated. Since the last reproduction is i = 1, when this reproduction is completed, the process proceeds from S369 to J in FIG. If no message is recorded or the play / stop button is pressed, the process proceeds to K in FIG.

If the repeat button is pressed, S37
At 6 the 1 second timer starts. When the repeat button is pressed again within 1 second, S377 to S380, S38
After shifting to 1, 1 is added to i, the flow returns to S376, and the 1 second timer is started. Therefore, every time the repeat button is pressed within 1 second, 1 is added to i, the process returns to S361 at the time up, and the i-th reproduction is performed.
If i becomes equal to m, the process from S380 to M in FIG.
Then, if the repeat button is pressed within 1 second, as described with reference to FIG. 19, it is possible to return to the reproduction of the memo recording and the reproduction of the conversation recording. When the skip button is pressed, the next message recording (recording immediately before) is skipped.

FIG. 20 shows a flow of ending the reproducing operation. The process proceeds from J in FIG. 20 or K in FIGS. 18 to 20. When the process shifts from J in FIG. 20, the timer set to 60 seconds in S400 is started, and S401 to S403 are executed.
Enter the loop. When the timer times out, the garbage operation from S403 to S406 to S408 is performed.
If the erase operation is performed during the reproducing operation, the process proceeds from S406 to S407, the garbage process is performed, and after the garbage is completed, the standby state starts from S408.

If the repeat button is pressed before the time-up of 60 seconds, if there is a message recording, S401, S40
20. Returning to R of FIG. 20, if there is no message recording and there is memo recording, the flow returns from S405 to N of FIG. 19, and if there is no memo recording, returns from S405 to L of FIG. If the play / stop button is pressed, the process proceeds from S402 to S406.

22 and 23 show the FA in the reproducing operation.
7 is a flowchart for explaining an outline of commands transmitted and received between the X section and the TAD section. During playback,
A loop is executed from S410 to S416. To enter the conversation reproduction operation, the conversation reproduction command is sent from the TAD section by FAX.
In step S410, the FAX unit that has received the message transmits the message "KAIWA SAISEI" to the LCD display unit in step S417. The conversation deletion command is transmitted from the TAD unit to the FAX unit, and the received F command is received in S411.
In step 418, the AX section displays "KAIWA SHOW KYOSHIMA SHITA" on the LCD display section. A memo reproduction command is transmitted from the TAD unit to the FAX unit, and in S412, the FAX unit which received the memo reproduction command is displayed in the LCD display unit in S419.
Display "Memo". A memo deletion command is transmitted from the TAD section to the FAX section, and S413 is executed.
Then, in the FAX unit that receives this, in S420, "Memo Show Kyoma Shita" is displayed on the LCD display unit.
The message reproduction command is transmitted from the TAD unit to the FAX unit, and in S414, the FAX unit which received this receives the number data and time stamp of the items to be subsequently transmitted in S421, and in S422, the LCD display unit displays "i". The display will be "Chem. X month x day x x: x x".

The end command and the reproduction end command are
When the X section receives it, the procedure moves to P in FIG. In the FAX section, a TAD command is issued for the absence setting request or home setting request command.
And wait for the setting command from the TAD section,
In the AD section, if data is erased during playback, DS
There is a case where a recording processing in which P is erased is deleted from the ICM, and garbage processing is performed to fill the remaining recording data in order. In this case, the TAD unit sends the during-garbage command to the FAX unit. In step S430, the FAX unit that received this message displays "SHIBARUKU OMAKUKUDA DAI" on the LCD display unit in step S431. The setting request command described above is repeatedly transmitted until the setting command is received. As for the setting request command, since the setting data is stored in the FAX unit, based on the setting data, if the answer setting is made in S432, the answer setting request command is sent in S433.
If it is a home setting, a home setting request command is sent to the TAD unit in S434. If the command received by the TAD unit in S435 is the answering machine setting request command, the TAD unit sets the answering machine, and in S437, sends the answering machine setting command to the FAX unit. TAD in S435
If the command received by the unit is the in-home setting request command, the TAD unit performs in-home setting, and in S438, transmits the in-home setting command to the FAX unit. Following the setting command, the TAD unit sends the remaining time data of the ICM, various information, and the number-of-messages data to the FAX unit. In the FAX section, S
At 439, after receiving this, it goes into a standby state. In the standby state, the date and time, the day of the week, and the time are displayed as shown in S440.

FIG. 24 is a flowchart of the initial state when the power is turned on after the power is restored after the power failure. S450 to S464 on the right side of the figure are FAX sections, and S470 to S481 on the left side are TAD sections. When the power failure is recovered, the FAX unit starts the startup program in S450. At the same time, in the TAD section, S470
Checks the backup battery voltage. The backup battery is for ensuring the power supply of the ICM, and when it is consumed, the contents of the OGM and the recorded message are erased. When OGM is not recorded, there is a problem in that it is not possible to set an answering machine.

As a result of the battery voltage check, if the voltage is not equal to or higher than the predetermined value, it is determined that the ICM is in the erased state, and the flag is set to 0 in S472. If there is voltage, S
At 471, the flag is set to 1. Then, DSP of S474
Go into self-check. In this embodiment, the self-check time requires about 40 seconds. In the FAX unit, after sending the home-setting request command in S451, S
At 452, the 2-second timer is started, and at S453, TA
Wait for the home setting command from the D section. In the TAD section, S
Even if the at-home setting request command is received at 473, the at-home setting command cannot be sent to the FAX unit because the checking is in progress. In the FAX unit, when the timer times out in S454, the process returns to S451, and the sending of the in-home setting command and the receiving of the in-home setting command are repeated. When the self-check of the DSP is completed in the loop of S473 to S475, the process proceeds from S475 to S476 to set at-home and then sends at-home setting command. After the setting command, the TAD section displays a flag and I
The remaining time data of the CM, various information, and the number of messages data are FA
Send to Part X. The FAX unit receives the at-home setting command in S453, receives the data in S455, and proceeds to S456.

In S456, the state of OGM is checked. The check confirms that the OGM is erased on condition that the flag is 0 and the number of data is 0. If both are 0, the process proceeds to S457, the battery replacement alarm LED is turned on, and, for example,
A message "Message Message Show Message" is printed out from the recording unit in the FAX unit.
This message is stored in a ROM or the like in advance, and is read out at the time of print output and given to the recording unit of the FAX unit. The storage capacity of the message can be reduced by storing the message with a character code and converting it into bit data using a character generator. Of course, it may be stored as bit data. When the printout is made, the recording paper is outputted, so that it can be surely notified that the OGM has been erased, which is effective in avoiding overlooking.

Subsequently, the flag is 1 and the FAX
If the memory of the setting state in the department is the absence setting, S
At 459, an answering machine setting request command is transmitted. In S478, the TAD unit receives the setting request, and if this is an absence setting, the process proceeds from S479 to S480, performs an absence setting, and sends an absence setting command to the FAX unit. Next, in S480, remaining time data of ICM, various information,
The number-of-messages data is sent to the FAX section. If the answering machine is not set, the at-home setting has already been made, so that the standby state starts from S479. The FAX unit receives the absence setting command in S460, and receives the data in S461. S4
At 62, turn on the absence lamp and turn on the automatic reception lamp.
Then, in S464, the date, the day of the week, and the time are displayed, and the standby state is set. If the absence setting cannot be made in S458, the home setting is left as it is, and the absence lamp is turned on in S463.
If it is set to FF, the above-mentioned display is performed in S464, and a standby state is set.

In the above-mentioned embodiment, the recording state of the OGM is confirmed by the voltage of the battery.
