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). The reason for switching to the facsimile communication circuit 7 and selecting the facsimile mode in step 8 is that 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, the presence / absence of a voice signal is detected through the voice signal detection circuit for a predetermined time T3. If the voice signal is detected, the answering machine mode is selected, and if not detected, the facsimile mode is selected.

[0009]

With this structure, even if the handset is not picked up within the predetermined time T2, if the voice signal is detected within the predetermined time T3, the mode is switched to the answering machine mode, and the calling side can blow the message into the answering machine. .

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. However, the same parts as those of the conventional example are designated by the same reference numerals, and a duplicate description will be omitted.

FIG. 1 is a block diagram showing a configuration of a main part in an embodiment of a facsimile machine with a telephone function of the present invention, and FIG. 2 is a home mode setting in an embodiment of a fax machine with a telephone function of the present invention. FIG. 3 is a flowchart showing the operation of selecting various modes at the time, and FIG. 3 is a flowchart showing the operation of selecting various modes at the time of setting the answering mode in the embodiment of the facsimile apparatus with the telephone function of the present invention.

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, the audio signal detection circuit 11 detects the presence or absence of an audio signal for a predetermined time T3 after the elapse of the predetermined time T2 for emitting a ringing tone (step 11),
If no voice signal is detected, the mode is switched to the facsimile mode (step 12), and if detected, the current telephone mode is switched to the answering machine mode (step 13). By the confirmation operation in step 11 of the voice signal detection circuit 11, even if the handset is not picked up within the predetermined time T2, if the voice signal is detected within the predetermined time T3, the voice mail mode is switched to the answering machine mode, and the calling side answers the message. You can blow into the phone.

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 then, 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 11). The predetermined time T3 is usually set to about 4 seconds, but the beginning of the message is usually "Eh ... here" or "Uh ... here", which is a word unrelated to the essence of the message. This is because if it is about 4 seconds, the recording at the beginning can be ignored. If no voice signal is detected, the facsimile communication circuit 7 is switched to and the facsimile mode is selected (step 12). When the voice signal is detected, the answering machine mode is selected (step 13) and the recording device 10 composed of a tape or an IC is operated to record the received voice signal (step 14).

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 a result, according to the present invention, it is possible to switch to the answering machine mode regardless of whether the home mode, the answering mode, or the initial setting.

In the above description, it is assumed that the home mode and the absence mode are processed independently.
However, the flow from step 11 to step 13 in FIG. 2 may be changed to the flow from step 11 in FIG. 2 to step 9 in FIG. 3 to combine the home mode and the absence mode.

[0018]

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 not, the presence / absence of a voice signal is detected through the voice signal detection circuit for a predetermined time T3. If the voice signal is detected, the answering machine mode is selected, and if not detected, the facsimile mode is selected.

With this configuration, even if the handset is not picked up within the predetermined time T2, if the voice signal is detected within the predetermined time T3, the mode is switched to the answering machine mode, and the calling side can blow the message into the answering machine. .
