[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine with an answering machine recording function capable of switching between a recording operation for recording a voice message from a calling side and a facsimile operation for transmitting / receiving image data to / from the calling side. It is about.

[0002]

2. Description of the Related Art In a facsimile machine with an absence recording function of this kind, when a call is received in an absence mode, a response message is sent out and then the operation of the recording device is started. Even if this recording operation is started, when a facsimile signal such as a CNG signal sent from the calling side is detected, the connection with the telephone line is switched from the recording device side to the facsimile device main body side to perform facsimile communication. It has become. In the conventional device, if the facsimile operation is started after the recording operation is started, the recorded content is erased in any case.

[0003]

Therefore, in the above-mentioned conventional facsimile apparatus, the recorded contents are erased even when the facsimile communication is performed after the voice message from the calling side is transmitted. Therefore, in such a case, there is a problem that it is inconvenient because the voice message from the calling side cannot be known.

Further, conventionally, it has also been proposed that when the facsimile operation is started after the recording operation is started, the recorded content is left without being erased. However, in the case of such a configuration, when facsimile communication is performed from the calling side without a voice message, C of 1100 Hz is generated.
There is a problem that only the NG signal is recorded or a silent state is recorded, which is uncomfortable during reproduction and the memory capacity of the recording device is wasted.

The present invention has been made by paying attention to the problems existing in such a conventional technique, and its purpose is to make a call when a facsimile operation is started after a recording operation is started. Another object of the present invention is to provide a facsimile apparatus with an absence recording function that can leave recorded contents when there is a voice message from the side and can erase recorded contents when there is no voice message.

[0006]

In order to achieve the above object, the present invention provides a recording operation for recording a voice message from a calling side and a facsimile operation for transmitting / receiving image data to / from the calling side. In a facsimile apparatus which is switchable and has erasing means for erasing recorded contents, the erasing means deletes the recorded contents when the facsimile operation is started within a predetermined time after starting the recording operation. It is configured.

[0007]

[Operation] In the facsimile apparatus with an answering machine recording function configured as described above, when a call is received, a recording operation is started after a response message is transmitted. Also, after the recording operation is started, for example, C sent from the calling side.
When a facsimile signal such as an NG signal is detected, the facsimile operation is started.

If the transition time to the facsimile operation is within a predetermined time from the start of the recording operation,
It is considered that the facsimile communication was performed from the calling side without a voice message, and the recorded content is deleted. In addition, if the transition time to the facsimile operation exceeds a predetermined time from the start of the recording operation, it is considered that the facsimile communication is performed after the voice message from the calling side, and the recorded content remains as it is. Be done.

The ML relay 36 is provided to selectively connect the telephone line 5 to the modem 10 side and the telephones 4 and 37 side of the facsimile apparatus main body 2. As this telephone, in addition to the auxiliary telephone 4 provided integrally with the facsimile apparatus 1, a slave telephone 37 that can be connected to the facsimile apparatus 1 via a cable (not shown) is provided. When the CML relay 36 is switched to the a contact side by the control of the CPU 7 of the facsimile apparatus main body 2, the telephone line 5 is connected to the telephones 4 and 37 side. On the other hand, when the CML relay 36 is switched to the b contact side, the telephone line 5 is connected to the modem 10 side via the transformer 38.

The incoming detection circuit 39 has a photocoupler, and
The ED 39a is connected to the a contact side of the CML relay 36, and the phototransistor 39b is connected to the facsimile apparatus main body 2
Connected to the CPU 7. Then, the CPU 7 monitors the on / off state of the phototransistor 39b and detects the presence or absence of a call signal of 16 Hz on the telephone line 5. First and second
The off-hook detection circuits 40 and 41 are connected to the auxiliary telephone 4 and the slave telephone 37, and include the off-hook state of each telephone 4 and 37 (the state of picking up the handset, and the operating state of the recording device 3 in the case of the auxiliary telephone 4). ) Is detected, and the detection result is detected by the CPU 7 of the facsimile apparatus main body 2.
Output to. The detection result from the first off-hook detection circuit 40 on the accessory telephone 4 side is also output to the dial CPU 21 of the accessory telephone 4.

The DC voltage generating circuit 42 is used for the telephones 4, 37.
This is to supply a predetermined current to the telephones 4 and 37 in order to detect the off-hook of
24V is applied. That is, when the telephones 4 and 37 are off-hooked, the change in the current supplied to the telephones 4 and 37 is detected by the off-hook detection circuits 40 and 41. Then, based on the current detection by the off-hook detection circuits 40 and 41, the CP of the facsimile apparatus main body 2 is detected.
The dial CPU 21 of the U7 and the attached telephone 4 recognizes the off-hook state.

The DC voltage generating circuit 42 is connected to the telephones 4 and 37 via the TEL relay 43 and the telephone line 5 is connected.
And is switchably connected. Then, under the control of the CPU 7 of the facsimile apparatus main body 2, when the TEL relay 43 is connected to the a contact side, the telephones 4 and 37 are connected to the telephone line 5 side. On the other hand, when the TEL relay 43 is connected to the b contact side, the telephones 4 and 37 are connected to the DC voltage generating circuit 42 side. The transformer 44 is connected to the telephones 4 and 37, and the output side thereof is connected to the modem 10.

As described above, this facsimile machine 1
Then, by operating the absence key 32, the absence / FAX mode is set or released. Incidentally, when this mode is released, the operation mode of the apparatus is set to the telephone / FAX mode.

That is, when a calling signal is sent from the calling side when the answering machine / FAX mode is set, the CPU 7 of the facsimile apparatus main body 2 detects the calling signal via the incoming call detection circuit 39. When the CPU 7 detects the calling signal a predetermined number of times (twice in this embodiment),
An incoming call command signal is output to the CPU 24 of the recording device 3 to notify the CPU 24 of the incoming call. Then, C of the recording device 3
The PU 24 operates the DSP 27 to read the data of the voice response message which is previously recorded and stored in the RAM 30. Then, the DSP 27 decodes the data of the voice response message by the encoding / decoding circuit 31 and sends it to the telephone line 5 via the NCU 6.

After that, when the reading of the voice response message is completed, the CPU 24 of the recording device 3 starts the recording operation of the DSP 27, and at the same time sends a recording start signal to the CPU 7 of the facsimile main body 2 to start recording to the CPU 7. Let me know. Then, when the voice message is transmitted from the transmitting side, the DSP 27 encodes the data of the voice message by the encoding / decoding circuit 31, and the R
Store in AM30.

In this embodiment, the maximum recordable time of the RAM 30 is 20 minutes, and the maximum recordable time for one recording operation is set to 5 minutes. Then, the data of the voice message from the calling side is R for each recording operation.
It is sequentially accumulated in the AM 30. Therefore, the shorter the recording time in one recording operation, the more times the voice message from the calling side can be recorded.

Further, as shown in FIG. 2, after the recording operation is started, the CNG from the calling side is transmitted through the tone detection circuit 12.
When a signal is detected twice or a silent state is continuously detected for 6 seconds within 70 seconds from the start of the recording operation, the CPU 7 of the facsimile apparatus main body 2 switches the CML relay 36 from the a contact side to the b contact side. . That is, the CPU 7 of the facsimile apparatus main body 2 determines that the calling side is the facsimile apparatus, and connects the telephone line 5 to the telephones 4 and 3.
The side 7 is switched to the side of the modem 10 to start the facsimile operation according to a predetermined facsimile procedure.

Further, in this embodiment, the CPU 7 of the facsimile apparatus main body 2, the CPU 24 of the recording apparatus 3, the DSP 2
7, and the RAM 30 in the DSP 27 constitute an erasing means.

That is, the CPU 7 of the facsimile apparatus main body 2
When the recording start signal is input from the CPU 24 of the recording device 3, the timer 15 operates the timer 15 to measure 10 seconds. Then, the CPU 7 of the facsimile apparatus main body 2 causes the CPU 24 of the recording apparatus 3 to end the recording while the timer 15 measures 10 seconds, that is, when the facsimile operation is started within 10 seconds from the start of the recording operation of the DSP 27. An erase command signal (hereinafter referred to as an erase command signal) is transmitted.
Further, when the transition time to the facsimile operation has passed the 10 seconds, the CPU 7 of the recording device 3 C
A recording end command signal is sent to the PU 24.

When the erasing command signal is input, the CPU 24 of the recording device 3 stops the recording operation of the DSP 27 and erases the recording data stored in the RAM 30 by this recording operation. Also, the CPU 24
When the recording end command signal is input, the DSP 27 stops the recording operation, and the recording operation causes the RAM 30 to operate.
The recorded data stored inside is retained as it is.

Although not described in detail, absence / fax
The case where the mode is canceled and the telephone / FAX mode is set will be described. The CPU 7 of the facsimile apparatus main body 2 receives the ringing signal from the calling side by the incoming call detection circuit 39.
When it is detected twice via the CML relay 36, the CML relay 36 is switched to the b contact side, a pseudo ringback tone is sent to the calling side, and the detection of the CNG signal from the calling side is started. Then, when the CNG signal is detected and it is determined that the transmitting side is the facsimile apparatus, the operation proceeds to a facsimile operation according to a predetermined facsimile procedure.

If the CNG signal is not detected yet after the pseudo ring back tone is transmitted a predetermined number of times, the calling side may be a telephone.
Activates the buzzer 17 to generate a buzzer sound. Then, when the auxiliary telephone 4 or the slave telephone 37 is off-hooked based on the buzzer sound, the CML relay 36 is switched to the a contact side, and when the calling side is a telephone, a call is possible. Even if the caller is off-hook when the caller is a facsimile machine, the caller CNG
When a facsimile signal such as a signal is sent out, the facsimile operation is started. Even if the off-hook is not performed, the facsimile operation is started after a predetermined time.

Next, the operation of the facsimile apparatus with an absence recording function constructed as described above will be described with reference to the timing chart of FIG. 2 and the flow charts of FIGS. The programs of FIGS. 3 and 4 and the program of FIG. 5 are mutually related and proceed in parallel.

At the time of reception by the facsimile machine with the absence recording function, the facsimile machine main body 2
Under the control of the CPU 7, the operation shown in the flowcharts of FIGS. 3 and 4 is performed. The operation mode of the apparatus is set to the absence / FAX mode, and in this state, the CML relay 36 and the TEL relay 43 are switched to the a contact side as shown in FIG.

When a calling signal of 16 Hz is transmitted from the calling side through the telephone line 5 and the calling signal is detected twice through the incoming call detection circuit 39, the CPU of the recording device 3
An incoming call command signal is sent to 24 via the serial bus 26 to notify the incoming call (steps S1 to S).
2).

Thereafter, the transmission of the voice response message by the recording device 3 is completed, and it is waited for the recording start signal indicating the start of the recording operation to be input from the CPU 24 of the recording device 3 (step S3). Although not shown in the flowchart, if the auxiliary telephone 4 or the sub telephone 37 is off-hook before the recording start signal is input from the CPU 24 of the recording device 3, the operation of the recording device 3 is stopped. ,
Talking is possible.

When a recording start signal indicating the start of the recording operation is input from the CPU 24 of the recording device 3 in the step S2, the timer 15 is activated to start the measurement for 10 seconds (step S4). And timer 1
The following determination operation shown in FIGS. 3 and 4 is performed from the time when 5 is activated to the time when the first off-hook detection circuit 40 detects the on-hook of the recording device 3. That is, while the recording device 3 is recording, the CNG
Presence / absence of twice signal detection, presence / absence of continuous silence for 6 seconds, slave telephone 37 and auxiliary telephone 4 (handset 2
3) The presence / absence of off-hook, the presence / absence of operation of a stop key (described later), and the presence / absence of detection of on-hook of the recording device 3 by the first off-hook detection circuit 40 are performed (steps S5 to S10).

The above-mentioned determination operation will be described below in order.
As shown in FIG. 3, first, it is determined whether or not the CNG signal is detected twice, and when the CNG signal is detected twice, it is determined whether or not the timer 15 is within 10 seconds (step S5). , S11). If the result of this judgment is YES, that is, the CNG signal becomes 2 within 10 seconds after the input of the recording start signal.
When the number of times of detection is detected, it is considered that there is no voice message from the calling side, and a deletion command signal is sent to the CPU 24 of the recording device 3 (step S12). When the CNG signal is detected twice after 10 seconds have elapsed from the input of the recording start signal, it is considered that there is a voice message from the calling side, and the CPU 24 of the recording device 3 is notified of the recording end command signal. The instruction is sent (step S13).

At the same time as one of these signals is transmitted, the CML relay 36 is switched to the b contact side, the telephone line 5 is connected to the modem 10 side,
According to a predetermined facsimile procedure, the facsimile operation for receiving the image data from the transmitting side is started (step S14).

That is, when the CNG signal is detected twice from the calling side, it is determined that the calling side is a facsimile machine. Then, after the transmission of the CED signal and the DIS signal to the calling side and the exchange of a predetermined facsimile signal such as the reception of the DCS signal from the calling side, the recording unit 14 is operated and transmitted from the calling side. Image data is printed on the recording paper. When the facsimile reception operation is completed,
The line is disconnected, and in the absence / FAX mode, it returns to the reception standby state.

The CNG signal is regularly transmitted from the transmitting side for 0.5 seconds at intervals of 3 seconds. The above-mentioned detection of the CNG signal twice means that the CNG signal is continuously detected twice at an interval of 3 seconds. That is, the frequency of the CNG signal is 1100 Hz, and the frequency band of human voice is 11
It is a band including a frequency of 00 Hz. Therefore, if the CNG signal is detected only once, is it a human voice signal?
It cannot be reliably determined whether the signal is an NG signal. But,
The CNG signal is regularly sent every 0.5 seconds at intervals of 3 seconds, while the voice signal is randomly sent. Therefore, if a signal of 1100 Hz is detected twice consecutively at an interval of 3 seconds, this signal is definitely a CNG signal, and it can be surely determined that the transmitting side is a facsimile machine. It If the time from the first detection to the second detection of the 1100 Hz signal is outside the range of 2.5 to 6 seconds, this signal is not judged as a CNG signal and the facsimile operation is not started.

When the CNG signal is not detected twice in step S5, it is determined whether or not a continuous silent state for 6 seconds is detected (step S5).
6). If the result of this determination is YES, it is determined whether or not the silent state detection time is within 70 seconds after the recording start signal is input from the CPU 24 of the recording device 3 (step S15). If it is within 70 seconds, a recording end command signal is sent to the CPU 24 of the recording device 3 (step S16), and thereafter, the process proceeds to step S14.
In addition, the silence detection time is 7 from the input of the recording start signal.
If 0 seconds has elapsed, the CPU 24 of the recording device 3
A recording end command signal is sent to (step S17), then the line is disconnected and the system returns to the standby state.

That is, the fact that no voice signal or the like is detected for 6 consecutive seconds and no sound is present means that the transmission of the voice message from the calling side has been completed or there is no voice message. It When the silent state is detected from the input of the recording start signal, that is, when 70 seconds have elapsed from the start of recording, it is determined that the caller side did not perform the facsimile communication with only the voice message. , A recording end command signal is sent to the CPU 24 of the recording device 3 to disconnect the line. If the silent state is detected within 70 seconds after the recording is started, it is determined that the facsimile communication has been performed after the voice message is transmitted by the caller or without the voice message. Then, in step S5, the fact that the CNG signal is not detected means that the CNG signal has not been detected because the facsimile communication was manually performed on the transmitting side, and then the facsimile operation is started.

If no silence is detected at step S6, as shown in FIG. 4, it is determined whether or not the off-hook detection signal of the slave telephone 37 is input from the second off-hook detection circuit 41. (Step S
7). Then, when the off-hook detection signal is input, the recording end command signal is sent to the CPU 24 of the recording device 3 and the call becomes possible (step S18).
~ S19). When the handset 23 of the auxiliary telephone set 4 is off-hook, the call end state is established without sending the recording end command signal (steps S8, S1).
9).

The CPU 7 of the facsimile apparatus main body 2
Recognizes the off-hook state of the attached telephone 4 based on the detection signal from the first off-hook detection circuit 40. However, the first off-hook detection circuit 40 detects not only the state where the handset 23 is actually off-hook, but also the state where the recording device 3 is operated as an off-hook state. Therefore, the CPU of the facsimile apparatus main body 2
7, it cannot be determined whether the detected off-hook state is off-hook of the handset 23 or off-hook due to the operation of the recording device 3.

Here, the on / off hook state of the handset 23 is determined by dial C based on the on / off state of a hook switch provided on a handset holder (not shown).
The PU 21 detects and notifies the CPU 24 of the recording device 3. Then, the CPU 24 of the recording device 3
When the handset 23 is picked up and the fact that the hook switch has been turned off is notified, the recording operation is stopped, and then the call becomes possible.

Therefore, the handset 23 in step S8
The CPU 24 of the recording apparatus 3 actually does not perform the operation of determining whether or not is off-hook, but it is not performed by the CPU 7 of the facsimile apparatus main body 2. However, for convenience, this step S8 is performed.
Described in.

In step S19, if the calling side is a telephone, a call is made between the two parties, and if facsimile communication is desired after the call ends, a start key (not shown) is operated to start a facsimile operation. Will be migrated. Further, when the originating side is a facsimile machine, when a facsimile signal such as a CNG signal is sent out, the operation is shifted to a facsimile operation. After the telephone call or facsimile communication is performed, the line is disconnected and the standby state is restored.

In the steps S7 and S8,
If the off-hook detection signal is not input, it is determined whether or not a stop key (not shown) has been operated (step S9). The stop key is connected to the CPU 7 of the facsimile apparatus main body 2 and is for stopping the facsimile operation and the like. When the stop key is operated, a recording end command signal is sent to the CPU 24 of the recording device 3 (step S20), the line is disconnected thereafter, and the standby state is restored.

In steps S5 to S10, the first off-hook detection circuit 40 turns on-hook the recording device 3 under the condition that the CNG signal, the silent state, the off-hook state of the telephones 37 and 4 and the operation of the stop key are not detected. When is detected, the line is disconnected and the system returns to the standby state.
For example, during the recording operation, when a busy tone is detected on the recording device 3 side or the maximum recording time of 5 minutes elapses,
The recording device 3 is hooked on. When the first off-hook detection circuit 40 detects the on-hook of the recording device 3, the determination in step S10 becomes YES, the line is disconnected and the standby state is restored.

On the other hand, in response to the operation of the facsimile apparatus main body 2, the recording apparatus 3 performs the operation shown in the flowchart of FIG. 5 under the control of the CPU 24. That is, when an incoming command signal is input from the CPU 7 of the facsimile apparatus main body 2 (step S31), the DSP 2
7 is activated to read the data of the voice response message in the RAM 30. Then, the data of the voice response message is decoded by the encoding / decoding circuit 31,
The data is sent to the calling side via the NCU 6 and the telephone line 5 (step S32). Although not shown in the flow chart, while the voice response message is being sent, the attached telephone 4
Alternatively, when the slave telephone 37 is off-hook, the DSP 27 stops sending the voice response message and returns to the standby state.

After that, when the transmission of the voice response message is completed, the recording operation of the DSP 27 is started and the recording start signal is sent to the CPU 7 of the facsimile apparatus main body 2 (steps S33 to S35). Then, when the voice message is transmitted from the transmitting side, the data of the voice message is encoded by the encoding / decoding circuit 31 and stored in the RAM 30. In addition, C from the calling side
When the NG signal is transmitted, this CNG signal is also recorded and stored in the RAM 30.

While the maximum recording time of 5 minutes elapses from the start of the recording operation, the CPU of the facsimile apparatus main body 2
When an erasing command signal is input from 7, the recording operation of the DSP 27 is stopped and RA
The recorded data stored in M30 is erased (steps S36 to S38). Then, after that, it returns to the standby state.

When a recording end command signal is input while the above 5 minutes have elapsed, the recording operation of the DSP 27 is stopped, and the recording data stored in the RAM 30 is retained as it is by this recording operation ( Steps S39 to S4
0). Then, after that, it returns to the standby state.

Further, while the above five minutes have elapsed, the off-hook of the handset 23 of the attached telephone 4 is turned off by the dial CPU 2.
If it is detected through 1, the process proceeds to step S40 (step S41). In this case, the call is ready. If a busy tone is detected by the DSP 27 while the above 5 minutes have elapsed, the same step S40 is performed.
(Step S42).

Then, the erase command signal is input, the recording end command signal is input, the off-hook of the handset 23 is detected,
Alternatively, after 5 minutes have passed without the busy tone being detected, the recording operation of the DSP 27 is stopped, and the recording data stored in the RAM 30 by this recording operation is retained as it is (step S43). Then, it returns to the standby state.

As described above, in the facsimile apparatus with an answering machine recording function of this embodiment, when an incoming call is received when the answering machine / FAX mode is set, the DSP 27 of the recording apparatus 3 is operated and the voice response message in the RAM 30 is sent. , And then the recording operation is started. After the recording operation is started, if the CNG signal from the calling side is detected twice or the silent state is continuously detected for 6 seconds within 70 seconds from the start of recording, it is determined that the calling side is a facsimile machine. Then, the facsimile operation is started.

Then, the detection timing of the CNG signal, that is, the transition timing to the facsimile operation is 1 from the start of the recording operation.
If it is within 0 seconds, it is considered that the caller side has performed facsimile communication without a voice message, the recording operation is stopped, and R
The recorded data stored in the AM 30 is deleted. or,
The transition time to the facsimile operation is 1 from the start of the recording operation.
When 0 seconds has elapsed, it is considered that the facsimile communication was performed after the voice message from the calling side, the recording operation is stopped, and the recording operation stored in the RAM 30 is performed by this recording operation. The data is retained as is.

That is, it is considered that there is no voice message from the calling side when shifting to the facsimile operation within a short time of 10 seconds from the start of the recording operation.
In such a case, since the recorded contents are erased, it is possible to surely prevent the user from feeling uncomfortable at the time of reproduction because only the CNG signal of 1100 Hz is recorded or the silent state is recorded. At the same time, it is possible to reliably prevent the storage capacity of the RAM 30 of the recording device 3 from being wasted. Further, it is considered that there is a voice message from the calling side when shifting to the facsimile operation in a long time of 10 seconds or more from the start of the recording operation. In such a case, the recorded content is not erased and remains, so that the voice message from the calling side can be known, and the recorded content is erased even if there is a voice message, which is inconvenient. There is no.

The present invention is not limited to the configuration of the above-described embodiment. For example, the time measured by the timer 15 may be changed to another appropriate time instead of 10 seconds, and the silence detection time may be other than 6 seconds. Or change the CNG signal to 1
It is also possible to embody by arbitrarily changing the configuration of each unit within a range not departing from the spirit of the present invention, such as shifting to a facsimile operation when detected once.

[0060]

Since the present invention is configured as described above, when the facsimile operation is started after the recording operation is started, the recorded contents can be left when the message is sent from the calling side and the message can be left. When there is no sound, it has an excellent effect that the recorded contents can be erased.
