FIG. 5 is a flowchart showing an operation of selecting various modes when a home mode is set in the conventional facsimile apparatus with a telephone function. FIG. 6 is a flowchart showing the operation of selecting various modes when setting the answering machine mode in the conventional facsimile apparatus 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 this (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 a facsimile communication start signal, that is, the presence or absence of a CNG signal for a predetermined time T1 (typically about 4 seconds) (step 3). The control means 3 controls the switching circuit 6 in accordance with the presence or absence of the CNG signal detection. If the CNG signal is detected, the control means 3 switches to the facsimile communication circuit 7 to select the facsimile mode (step 4). 8 to select the telephone mode (step 5). In the telephone mode, during a predetermined time T2 when the counting of the timer 9 ends (the normal ringing
A ringing tone is emitted (during ~ 6 times), and the control means 3 determines whether or not the handset is picked up during that time (step 6),
When the receiver is picked up by the predetermined time T2, the current telephone mode is selected to enable the telephone call (step 7), and the predetermined time T
Facsimile communication circuit 7 if handset is not picked up by 2
To select the facsimile mode (step 8). The reason why the facsimile communication mode is selected by switching to the facsimile communication circuit 7 in step 8 is that if the transmitting side operates the facsimile in the automatic mode, the CNG signal is immediately transmitted. This is because some models cannot be used, so even if it is determined that the communication is telephone communication, facsimile communication may actually occur.

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 this (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 CNG signal for a predetermined time T1 (step 3). The control means 3 controls the switching circuit 6 according to the presence or absence of the CNG signal detection, and when the CNG signal is detected, switches to the facsimile communication circuit 7 and selects the facsimile mode (step 4). If the CNG signal is not detected, the mode is switched to the telephone communication circuit 8 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 a telephone function as described above, when the home mode is set, the mode is switched to the facsimile mode unless the receiver is picked up within a predetermined time T2.
For example, if the ringing of the handset is delayed due to the noise of the vacuum cleaner and the handset cannot be picked up in time, the mode is automatically switched to the facsimile mode, and the call is made even though the called user is at home. Calling from the calling side 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 message cannot be recorded from the calling side.

[0007] The present invention solves the above 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 according to the subsequent situation judgment. A facsimile apparatus with a telephone function is provided.

[0008]

In order to achieve the above object, according to the present invention, even when the home mode is set, when a ring signal is input, the control means transmits a predetermined time T through a CNG signal detection circuit.
The CNG signal is detected for 1 and the mode is switched to the facsimile mode if the CNG signal is detected. If the CNG signal is not detected, a ringing tone is emitted for a predetermined time T2. If the receiver is not picked up, the presence or absence of a voice signal is detected for a predetermined time T3 through the voice signal detection circuit. If the voice signal is detected, the mode is switched to the answering machine mode, and if not detected, the mode is switched to the facsimile mode.

[0009]

With this configuration, even if the receiver 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. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described hereinafter with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a configuration of a main part of a facsimile apparatus with a telephone function according to an embodiment of the present invention. FIG. 2 is a diagram showing a home mode setting in an embodiment of the facsimile apparatus with a telephone function according to the present invention. FIG. 3 is a flowchart showing the operation of selecting various modes when the answering machine mode is set in one embodiment of the facsimile apparatus with a telephone function of the present invention.

First, the outline of the present invention will be described with reference to FIGS. 1 and 2, when the home mode is set, in the conventional example, if a CNG signal is not detected within a predetermined time T1, a predetermined time T during which a ringing tone is emitted is given.
The control means 3 has switched from the telephone mode to the facsimile mode as long as the handset is not picked up during the time between the two. However, in the present invention, the last 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 a predetermined time T2 for generating a ringing tone has elapsed (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). If the voice signal is detected within the predetermined time T3 even if the handset is not picked up within the predetermined time T2 by the confirmation operation in step 11 of the voice signal detection circuit 11, the mode is switched to the answering machine mode, and the calling side switches the message to the answering machine mode. You can speak on the phone.

Hereinafter, an embodiment of a facsimile apparatus with a telephone function according to the present invention will be described in detail with reference to FIGS.

First, the case where the home mode is set will be described. 1 and 2, when a ring signal is input from the telephone line 1, the ring signal detection circuit 2 detects this (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 control the CNG signal detection circuit 5 for a predetermined time T1 (typically about 4 seconds).
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 the CNG signal detection, switches to the facsimile communication circuit 7 when the CNG signal is detected, selects the facsimile mode (step 4), and switches to the telephone communication circuit 8 when the CNG signal is not detected. To select the telephone mode (step 5). In the telephone mode, a predetermined time T2 at which the count of the timer 9 ends.
During this period (while the normal ringing tone is emitted three to six times), a ringing tone is emitted and it is determined whether or not the handset is picked up during that time (step 6). If the handset is picked up by the predetermined time T2, the current telephone mode is set. To enable a call (step 7). Up to this point, the operation is the same as the conventional example, but the predetermined time T2
If the receiver is not picked up by this time, the control means 3 controls the voice signal detection circuit 11 for a predetermined time T3 (normally about 4 seconds).
The presence or absence of an audio signal is detected (step 11). Usually, the predetermined time T3 is set to about 4 seconds, but the beginning of the message is usually uttered with words such as "er ... here" or "um ... here", which are not related to the essence of the business. If it is about 4 seconds, the beginning recording can be ignored. If no voice signal is detected, the mode is switched to the facsimile communication circuit 7 to select the facsimile mode (step 12). If a 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 answering mode is set will be described. 1 and 3, when a ring signal is input from the telephone line 1, the ring signal detection circuit 2 detects this (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 CNG signal for a predetermined time T1 (step 3). The control means 3 controls the switching circuit 6 according to the presence or absence of the CNG signal detection, and when the CNG signal is detected, switches to the facsimile communication circuit 7 and selects the facsimile mode (step 4). If the CNG signal is not detected, the mode is switched to the telephone communication circuit 8 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 mode is the home mode or the answering machine mode.

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, and the home mode and the absence mode may be combined.

[0018]

According to the facsimile apparatus with a telephone function of the present invention, even when the home mode is set, when a ring signal is input, the control means controls the CN through the CNG signal detection circuit for a predetermined time T1.
The G signal is detected. If a 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. If not, the presence / absence of a voice signal is detected for a predetermined time T3 through the voice signal detection circuit. If a voice signal is detected, the mode is switched to the answering machine mode, and if not detected, the mode is switched to the facsimile mode.

With this configuration, even if the receiver 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. .
