Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine with a telephone function having a telephone function and a facsimile function.

[0002]

2. Description of the Related Art A conventional facsimile machine with a telephone function receives a voice signal or an image signal sent through a telephone line by switching between various modes according to the situation of home or absence as described below. Was there.

FIG. 4 is a block diagram showing a configuration of a main part of a conventional facsimile machine with a telephone function, and FIG. 5 is a flowchart showing an operation of selecting various modes when a home mode is set in the conventional facsimile machine with a telephone function, FIG. 6 is a flow chart showing the operation of selecting various modes when setting the answering mode in the conventional facsimile machine with a telephone function.

First, the case where the home mode is set will be described. 4 and 5, when a ring signal is input from the telephone line 1, the ring signal detection circuit 2 detects it (step 1) and outputs it to the control means 3. The control means 3 controls the interface circuit 4 to close the telephone line 1 (step 2). Next, the control means 3 controls the CNG signal detection circuit 5 to detect the presence or absence of a facsimile communication start signal, that is, a CNG signal for a predetermined time T1 (usually about 4 seconds) (step 3). The control means 3 controls the switching circuit 6 depending on whether or not the CNG signal is detected. If the CNG signal is detected, the control circuit 3 switches to the facsimile communication circuit 7 to select the facsimile mode (step 4). If the CNG signal is not detected, the telephone communication circuit is selected. Switch to 8 and select the telephone mode (step 5). In the telephone mode, during a predetermined time T2 when the timer 9 finishes counting (normal ring tone is 3
A ringing tone is emitted, and the control means 3 determines whether or not the handset is picked up during that time (step 6),
When the handset is picked up by the predetermined time T2, the current telephone mode is selected to enable communication (step 7), and the predetermined time T
If the handset is not picked up by 2 the facsimile communication circuit 7
And the facsimile mode is selected (step 8). Why switch to the facsimile communication circuit 7 in step 8 to select the facsimile mode? When the sender operates the facsimile in the automatic mode, the CNG signal is immediately issued, but when operated in the manual mode, the CNG signal is not emitted at all. This is because there are models that cannot be used, and even if it is determined that the communication is telephone communication, there may actually be cases of facsimile communication.

Next, the case where the answering mode is set will be described. 4 and 6, when a ring signal is input from the telephone line 1, the ring signal detection circuit 2 detects it (step 1) and outputs it to the control means 3. The control means 3 controls the interface circuit 4 to close the telephone line 1 (step 2). Next, the control means 3 controls the CNG signal detection circuit 5 to detect the presence or absence of the CNG signal for a predetermined time T1 (step 3). The control means 3 controls the switching circuit 6 depending on whether or not the CNG signal is detected. When the CNG signal is detected, the control means 3 switches to the facsimile communication circuit 7 to select the facsimile mode (step 4). If the CNG signal is not detected, the telephone communication circuit 8 is switched to select the answering machine mode (step 9), and the recording device 10 composed of a tape or an IC is operated to record the received voice signal (step 10).

[0006]

However, in the configuration of the conventional facsimile apparatus with the telephone function as described above, when the home mode is set, the mode is switched to the facsimile mode unless the handset is picked up within the predetermined time T2.
For example, even if the ringing tone is delayed due to the noise of the vacuum cleaner and it is too late to pick up the handset, the mode automatically switches to the facsimile mode, and the calling user makes a call even if he / she is at home. The call from the caller becomes impossible.
Further, if the user on the called side forgets to set the answering machine mode and goes out, there is a problem that the calling side cannot record a message.

The present invention solves the above-mentioned problems, and when the home mode is set, even if the handset is not picked up within a predetermined time, the mode is switched to the answering machine mode or the facsimile mode depending on the situation. It is an object to provide a facsimile machine with a telephone function.

[0008]

In order to achieve the above object, the present invention has a control means through a CNG signal detection circuit for a predetermined time T when a ring signal is input even when a home mode is set.
The CNG signal is detected during 1, and if the CNG signal is detected, the mode is switched to the facsimile mode. If the CNG signal is not detected, a ringing tone is emitted for a predetermined time T2, and when the handset is picked up, the mode is switched to the telephone mode. If the handset is not picked up, switch to the answering machine mode and detect the presence or absence of a sound signal for a predetermined time T3 through the sound signal detecting circuit. If the sound signal is detected, the answering machine mode is maintained.
If it is not detected, the mode is switched to the facsimile mode. Further, once the telephone number ends in the answering machine mode, the home / absent mode setting is changed to the answering mode.

[0009]

With this configuration, even if the handset is not picked up within the predetermined time T2, the mode is switched to the answering machine mode. If the voice signal is detected within the predetermined time T3, the answering machine mode is maintained, so that the calling side sends a message. You can blow into your answering machine from the beginning. Also, even if you initially set the home mode, once you finish in the answering machine mode, the home / answer mode setting is reset to the answering mode. Therefore, the CNG signal detection result performed first from the next ring signal input. You can directly switch to answering machine mode or facsimile mode.

[0010]

First, the outline of the present invention will be described with reference to FIGS. In FIGS. 1 and 2, when the home mode is set, in the conventional example, if the CNG signal is not detected within the predetermined time T1, the ringing tone is output for the predetermined time T.
As long as the handset was not picked up during 2, the control means 3 switched from the telephone mode to the facsimile mode. However, in the present invention, the final confirmation operation is performed before switching to the facsimile mode. That is, after a lapse of a predetermined time T2 for issuing a ringing tone, the mode is switched to the answering machine mode (step 11), and the recording device 10 is operated so that the calling side can blow a message into the answering machine from the beginning (step 12). The control means 3 controls the audio signal detection circuit 11 to detect the presence or absence of an audio signal for a predetermined time T3 (usually about 4 seconds) (step 15). If no voice signal is detected, the recording device 10 is stopped and the facsimile communication circuit 7 is switched to select the facsimile mode (step 16). Step 11 if the voice signal is detected
The answering machine mode is maintained and the series of routines following Steps 11 to 13 and Step 15 are repeated until it is confirmed in Step 13 that the recording of the voice signal is completed. If it is confirmed in step 13 that the recording of the voice signal has been completed, the setting is changed from the home mode to the absence mode (step 14).
In this way, even if the home mode is initially set, the home / answer mode setting will be reset to answering mode once it ends in the answering machine mode. You have changed the mode setting for absence. Then, from the input of the next ring signal, the first C
According to the result of detection of the NG signal, the answering machine mode or the facsimile mode is directly switched, so that the switching operation can be performed quickly.

The details of an embodiment of the facsimile machine with telephone function of the present invention will be described below with reference to FIGS.

First, the case where the home mode is set will be described. In FIGS. 1 and 2, when a ring signal is input from the telephone line 1, the ring signal detection circuit 2 detects it (step 1) and outputs it to the control means 3. The control means 3 controls the interface circuit 4 to close the telephone line 1 (step 2). Next, the control means 3 controls the CNG signal detection circuit 5 for a predetermined time T1 (usually about 4 seconds) C
The presence or absence of an NG signal is detected (step 3). Control means 3
Controls the switching circuit 6 depending on the presence or absence of CNG signal detection, switches to the facsimile communication circuit 7 if a CNG signal is detected and selects the facsimile mode (step 4), and switches to the telephone communication circuit 8 if a CNG signal is not detected. To select the telephone mode (step 5). In the telephone mode, the predetermined time T2 when the timer 9 finishes counting
During this period (usually 3 to 6 times), it is judged whether or not the handset is picked up (step 6), and if the handset is picked up by the predetermined time T2, the current telephone mode is set. Is selected to enable communication (step 7). Up to this point, it is the same as the conventional example, but the predetermined time T2
If the handset is not picked up by this time, switch to answering machine mode, for example, "I am currently out of the office. If you are using a fax machine, please send it. Please tell us about the matter. ”(Step 11), tape or IC
When the recording device 10 constructed in (1) is operated and a voice signal is received, the message is made recordable from the beginning (step 12). After that, it is judged whether or not the recording of the voice signal is completed, in other words, in this step, it is disliked to blow a message to the answering machine and whether or not the calling side has completed the communication (step 13). When the recording of the voice signal is completed, the setting is changed from the home mode to the absence mode (step 14), and during communication, the control means 3 controls the voice signal detection circuit 11 for a predetermined time T3 (usually about 4 seconds). ) The presence or absence of a voice signal is detected (step 15). The predetermined time T3 is usually set to about 4 seconds, but if it is usually about 4 seconds, "Eh ... here" or "Uh ... here" or the beginning of the message is emitted and a voice signal is detected. This is because that. If no voice signal is detected, the recording device 10 is stopped, the facsimile communication circuit 7 is switched to, and the facsimile mode is selected (step 1).
6). If a voice signal is detected, the process returns to step 11 to maintain the answering machine mode, until the recording of the voice signal is completed in step 13, in other words, until the end of the message to be blown is confirmed in step 13 which comes after the second step, 11 to 13 and a series of routines following step 15 are repeated. If it is confirmed in step 13 that comes after the second time that the audio signal has been recorded, the process proceeds to step 14 and the setting is changed from the home mode to the absence mode. After the input of the next ring signal, the flow shifts to the flowchart shown in FIG. 3, and the switching operation can be performed quickly because the mode is directly switched to the answering machine mode or the facsimile mode according to the detection result of the CNG signal.

Next, the case where the absence mode is set will be described. In FIG. 1 and FIG. 3, when a ring signal is input from the telephone line 1, the ring signal detection circuit 2 detects it (step 1) and outputs it to the control means 3. The control means 3 controls the interface circuit 4 to close the telephone line 1 (step 2). Next, the control means 3 controls the CNG signal detection circuit 5 to detect the presence or absence of the CNG signal for a predetermined time T1 (step 3). The control means 3 controls the switching circuit 6 depending on whether or not the CNG signal is detected. When the CNG signal is detected, the control means 3 switches to the facsimile communication circuit 7 to select the facsimile mode (step 4). If the CNG signal is not detected, the telephone communication circuit 8 is switched to select the answering machine mode (step 9), and the recording device 10 composed of a tape or an IC is operated to record the received voice signal (step 10).

As described above, the facsimile apparatus with a telephone function of the present invention can be switched to the answering machine mode regardless of the home mode, the answering machine mode, or the initial setting.

[0017]

In the facsimile apparatus with telephone function of the present invention, even when the home mode is set, when the ring signal is input, the control means causes the CNG signal detection circuit to generate the CN for a predetermined time T1.
If the G signal is detected and the CNG signal is detected, the mode is switched to the facsimile mode. If the CNG signal is not detected, a ringing tone is emitted for a predetermined time T2, and if the handset is picked up during that time, the mode is switched to the telephone mode and the handset is picked up. If the voice signal is not detected, the voice signal detection circuit detects the presence or absence of a voice signal for a predetermined time T3 through the voice signal detection circuit. If the voice signal is detected, the voice mail mode is maintained. Further, once the telephone number ends in the answering machine mode, the home / absent mode setting is changed to the answering mode.

With this configuration, even if the handset is not picked up within the predetermined time T2, it switches to the answering machine mode, and if the voice signal is detected within the predetermined time T3, the answering machine mode is maintained. You can blow into your answering machine from the beginning. Also, even if you initially set the home mode, once you finish in the answering machine mode, the home / answer mode setting is reset to the answering mode. Therefore, the first CNG signal detection from the next ring signal input Depending on the result, you can directly switch to the answering machine mode or the facsimile mode.
