Abstract

PURPOSE:To receive both a voice signal and a facsimile signal through one telephone line only by sending a 1st reply message to a telephone line in response to an incoming call, activating a picture reception means when a silence state is consecutive for a prescribed time and outputting a 2nd reply message when the voice signal is detected. CONSTITUTION:When an incoming signal comes from a telephone line 9, a control means 10 outputs a control signal from an output terminal P5 to turn on a line closing means 7 thereby closing a telephone line 9. Then the simple 1st reply message is sent to the telephone line 9. So long as no voice signal comes from the caller side, a timer means 10a counts up and a 3rd changeover switch 6 is turned to the position of 'F' by a signal from an output terminal P6 of the control means 10, a signal from the output terminal P10 controls a facsimile section 5 into the operating state to enter the reception operation of the facsimile signal from the caller. When the caller responds to the 1st reply message from the caller, the 2nd reply message is sent to the telephone line 9.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a line terminal device capable of transmitting and receiving audio signals and receiving image signals via a telephone line.

Conventional technology Conventionally, in facsimile image communication, the called party must first perform an off-hook operation to close the line when receiving a call, and then transmit a control jII (protocol) signal. , the calling party waits until it receives it. However, when the calling side facsimile is sending a message using the automatic sending function, it takes a certain period of time (approximately 20 to 3
If the operation procedure signal is not received within 0 seconds), the called terminal device determines that it is not a facsimile and releases the line.

Problems to be Solved by the Invention Therefore, for the above-mentioned reason, the calling facsimile machine that is making a call using the automatic transmission function should not return an operating procedure signal within the above-mentioned predetermined time (instead of returning the calling facsimile). For facsimile machines equipped with a function that can record messages sent by the caller, that is, an answering machine function, there are two important factors: (1) the time it takes to send a response message to the caller; and (2) whether the caller wishes to receive facsimile communication. (3) Furthermore, when it is determined that the calling party wants facsimile communication, The sum of the three times must be within the above-mentioned fixed time (20 to 30 seconds), which is longer than the time to send the operating procedure signal to the calling party, so it is difficult for the caller who wishes to record the voice message to record the voice message. On the other hand, there is a problem in that the time during which a response message can be sent is extremely short.

Therefore, the present invention has been made in view of the above-mentioned prior art, and it is possible to receive both voice signals and facsimile signals using only one telephone line, and even when the called party is absent, such as at night or out of the house. It automatically responds, first sending out a simple short response message and information about the incoming call, then responding with a more detailed response message if a voice signal is detected, and then responding to the voice signal (message) from the calling party. ) is recorded by a recording device, and if there is no sound, the calling party determines that it is a facsimile device, and the facsimile receiving device records the image signal. .

Means for Solving the Problems In order to solve the above conventional problems, the line terminal device of the present invention includes a response message means for reproducing the first and second response messages and transmitting them into the telephone line; In response to the incoming call, the first response message is sent to the telephone line, and if the silent state continues for a predetermined period of time, the image receiving means is controlled to be in an active state, and after the first response message is sent, the image receiving means is activated for a predetermined period of time. and control means for controlling the transverse flute 2 to output a response message to the telephone line if a voice signal is detected within the range.

With this configuration, the first response message is a simple response, and when it is known that the caller wishes to make a voice call, the second response message is a sufficient response. It can be carried out.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the main parts of a line terminal device in an embodiment of the present invention.

In FIG. 1, reference numeral 1 indicates a response message means including reproduction means 1a, lb for first and second response messages, and a first changeover switch IC; 3 is a second selector switch for selectively connecting the response message means 1 and the reception message means to a telephone line; 4a is a switch connected to the telephone line; 4b is a CNG signal (also called a calling tone signal, a cyclic signal as shown in Fig. 1) sent from the calling side; Indicates that it is a voice terminal, and this signal is required for automatic calling terminals.
5 is a facsimile unit that receives the image signal sent from the calling side; 6 is the facsimile unit 6 that receives the signal from the calling side or the response message unit 1; or a third selector switch 7 for selectively connecting to the receiving message means 1;
8 is an incoming call detection means for detecting an incoming signal arriving at the telephone line 9; 10 is a control means for controlling the entire device; Consists of computers.

The operation of the facsimile machine with answering machine function configured as described above will be explained below with reference to the flowchart shown in FIG.

When an incoming signal arrives from the telephone line 9, the incoming call detection means 8
The detection signal is applied to the input terminal P1 of the control means 10 (STEP1). In response, the control means 10 outputs a control signal from the output terminal P5, turns on the line closing means 7, and closes the telephone line 9 (ST
EP2).

Thereafter, the control means 10 outputs a control signal from the output terminal P6 to set the third changeover switch 6 to the r T J side, and also changes the second changeover switch 3 to the r T J side by outputting the output from the output terminal P7.
○'', the first selector switch IC of the response message means 1 is switched to 'AJm' by the output from the output terminal P8. Then, the response message means 1 is activated by the output from the output terminal P9, and the first response message reproduction means 1a prompts the other party to respond by saying, "Yes, this is Matsushita Electric. Which one are you?" Send a simple first response message to the telephone line 9 (
STEP 3). Further, the control means 10 starts counting the built-in timer means 10a. Note that this timer means 10a is set to expire in 7 seconds (
STEP 4). Here, the signal from the telephone line 9 is passed through the line closing means 7 and the third changeover switch 6 to the voice detecting means 4.
a and the CNG signal detection means 4b. Detection signals from these detection means are applied to input terminals P2 and P3 of control means 10, respectively.

The control means 10 first starts sampling the signal applied to the input terminal P2 in order to determine the presence or absence of an audio signal (
STEP 5). If a voice signal is sent from the calling side and the voice signal does not stop, the control means 10 counts up the aforementioned timer means 10a, and then checks whether or not the timer means 10a has expired (STEP 12). If the time has not expired, the process returns to 5TEP5, and if the time has expired (that is, the silent state continues for 7 seconds), the process proceeds to 5TEP13.

Also, if some signal (voice, noise, or control signal) is detected from the calling party in response to the above-mentioned first response message, that is, if the calling party attempts to leave a message and If the calling party's facsimile machine is in automatic transmission mode and transmits a CNG signal, etc., the control The control operation by means 10 proceeds from 5TEP6 to 5TEP7, where it is first checked to see if it is a CNG signal. If a CNG signal is detected, 5TEP
Proceed to step 13.

In addition, if the CNG signal cannot be detected in 5TEP7, the signal from the telephone line 9 is a voice signal, noise, or CNG signal.
These signals are discriminated as being signals other than NG signals (intermittent sounds, continuous sounds, etc.). If the frequency and period are not determined, the control means 10 determines that it is a voice or noise signal and transmits 5T.
Proceed to EPIO. 5If it is determined in TEP8 that the sound is a continuous or intermittent sound with a specific frequency or period, 5
Proceeding to TEP9, the aforementioned timer means 10a is counted up and it is checked whether the timer means 10a has expired or not. If it has not expired, return to 5TEP5. This means that if the CNG signal is detected successfully in 5TEP7 (even if it is not detected, the CNG signal will be detected again until the above-mentioned timer expires).
This is to enable detection of NG signals.

When the timer means 10a expires at 5TEP9, the control means 10 proceeds to 5TEP10.

Here, the control means 10 sets the third changeover switch 6 to 'T J QQ by the output terminal P6, and sets the second changeover switch 3 to 'OJ (N) by the output terminal P7.
8, the first selector switch 1 of the means 1 responds by
Switch c to ' B J fllll respectively. Then, the output terminal P9 controls the response message means 1 to be in operation, and the response message (2) is reproduced from the reproduction means 1b saying, ``If you have an answering machine, please tell us what you need when the beep sounds.'' A second response message like this is sent to the telephone line 9 (STEPIO). Next, the control means 10 outputs a control signal from the output terminal P7 to switch the second selector switch 3 to the 'T J side, and further controls the receiving message means 2 to the operating state from the output terminal P4, so that the calling party Record the message sent from
11). When the recording operation of the message from the calling party is completed, the process proceeds to S'r'EP14.

In addition, at 5TEP13, the control means 10 switches the third changeover switch 6 to 'F J (till) through the output terminal P6, controls the operation state of the facsimile section 5 through the output terminal PIO, and selects from the calling side. The facsimile signal receiving operation begins. When the facsimile signal receiving operation is completed, the process proceeds to 5TEP 14.

At 5TEP 14, the control means 10 controls the line closing means 7 to be in the OFF state through the output terminal P5, thereby opening the telephone line 9 and waiting for the next incoming call.

Effects of the Invention As described above, the present invention provides a response message means for reproducing the first and second response messages and transmitting them into the telephone line, and a means for transmitting the first response message to the telephone line in response to an incoming call. If a silent state continues for a predetermined period of time, the image receiving means is activated, and if an audio signal is detected within a predetermined period of time after sending the first response message, a response message of the transverse flute 2 is sent. By comprising a control means for controlling output of the information to the telephone line, -
It is possible to receive both audio and image signals using only a regular telephone line, and it automatically answers even when the called party is absent, such as at night or when he or she is out of the office. If a voice signal is detected, a more detailed response message is sent, and the voice signal (message) from the calling party is recorded by a recording device, even if it is silent. For example, it is possible to determine that the calling party is a facsimile machine and record the image signal using the facsimile receiving device, which has great practical effects.
