Abstract

PURPOSE: To shorten waiting time and to simplify operation by automatically discriminating whether a received signal is a telephone signal or a facsimile (FAX) signal, transmitting a waiting signal during the period of discrimination, generating a ringback tone at the time of a telephone signal, or in the case of a FAX signal, automatically receiving the FAX signal and reproducing the received signal in a transmitted image. CONSTITUTION: This automatic switching device is constituted of a switching part 1, a discriminating part 2, a recording part 3, a control part 4, a FAX mechanism part 5, a waiting tone generating part 6, and a telephone mechanism part 7. After connecting a line, whether an input signal from the originating side is a FAX signal or not is automatically discriminated by the discriminating part 2, during the period of discrimination, a waiting tone is generated from the waiting tone generating part 6 to the originating side to inform waiting due to discrimination to the originating side. In the case of a telephone call, a ringback tone is generated and talking is started by the hook-off operation of the originating side. In the case of a FAX signal, the FAX signal is recorded, and at the time of receiving a transmission end signal, the FAX signal from the recording part 3 is reproduced in a transmitted image.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated terminal in which a telephone and a facsimile are connected to the same line, and in particular, it does not depend on a specific operation on the sending side after confirmation of a message from the receiving side.
The present invention relates to a terminal for automatically identifying a telephone signal or a facsimile signal.

[0002]

2. Description of the Related Art In the conventional telephone and facsimile integrated terminal, when transmitting a facsimile as shown in FIG.
After connecting to the receiving side, wait for the waiting voice from the receiving side to say "If you send a fax, press the send button after the dial tone. Otherwise, wait for a while." Had to press the submit button.

Similarly, in the case of a telephone, the transmitting side must wait for a standby voice and also while the ringing tone is sounding. When the receiving side is absent, the caller waits for an answering machine message to flow, and then the sender enters the message.

Further, in the conventional telephone / facsimile automatic switching device, a system is switched after off-hook depending on whether or not a CNG signal peculiar to a facsimile is detected (Japanese Patent Laid-Open No. 4-14).
4347, Japanese Unexamined Patent Publication No. 4-242364), an automatic incoming call, a CNG signal specific to a facsimile is detected, and a caller waits with a voice message during detection (Japanese Unexamined Patent Publication No. Hei 5-14583), or first after an automatic incoming call. There has been known one in which a ringing tone is transmitted from the receiving side (Japanese Patent Laid-Open No. 5-130312).

[0005]

In such a conventional telephone-facsimile integrated terminal, in the case of a telephone, waiting time on the calling side is long due to standby voice transmission and ringing tone transmission.
Furthermore, when sending a facsimile, it took time and effort to press the send button after checking the standby voice.

In addition, as in Japanese Unexamined Patent Publication No. 4-144347 "Automatic call / communication switching method in facsimile machine with built-in answering machine" and Japanese Unexamined Patent Publication No. 4-242364 "Automatic switching method of facsimile", whether or not the receiving side is off-hook is facsimile. It is not possible to discriminate whether or not the entire transmission time becomes long, and the entire transmission time becomes long as the guidance voice message is sent as in Japanese Patent Laid-Open No. 14583/1993, “Facsimile device with automatic switching function”. 130312
Since a ringing tone is sent out like a "facsimile device with an automatic switching function", there is a problem that the entire time becomes long.

An object of the present invention is to identify whether a received signal is a telephone signal or a facsimile signal within a short period of time, issue a signal to wait for that period, emit a ringing tone for a telephone signal, and automatically if a facsimile signal. Receiving and replaying to the transmitted image to reduce the waiting time and simplify the operation.

[0008]

According to the automatic telephone and facsimile switching method of the present invention, it is discriminated whether a signal connected from a telephone line and inputted from a telephone line is a facsimile signal or another signal, and the facsimile signal is used to switch to the facsimile side. When the facsimile signal is received, the reception mode of the facsimile is entered, the facsimile signal is recorded, the termination signal is received and the recorded facsimile signal is reproduced, or the caller is hooked off when the other signal is switched to the telephone side. It will ring tones until the answering machine is connected, and it will automatically connect to the answering machine when the answering machine is set. In the automatic switching method between the telephone and the facsimile, the calling side and the receiving side are connected and the caller waits at the same time. Emitting a signal that causes

Also, the signal that causes the caller to wait is 1
It is a waiting voice message of 2 seconds to 2 seconds.

Also, the signal that causes the caller to wait is 1
It is a standby chime sound by a timer of 2 seconds to 2 seconds.

Further, the automatic telephone / facsimile switching apparatus of the present invention discriminates whether the signal connected through the telephone line and inputted from the telephone line is a facsimile signal or another signal, and when the facsimile signal is switched to the facsimile side. In the facsimile reception mode, the facsimile signal is recorded, the termination signal is received and the recorded facsimile signal is reproduced, or when the other signal is switched to the telephone side, a ringing tone is emitted until the caller hooks off. Ringing, and when the answering machine is set, it will automatically connect to the answering machine. In the automatic switching device for telephone and facsimile, at the same time when the calling side and the receiving side are connected, a signal to cause the calling side to stand by is issued. Have means.

Further, the means for issuing a signal to cause the calling side to wait is a waiting voice sending unit for sending a waiting voice message for 1 second to 2 seconds or a chime sound for waiting.

[0013]

The automatic telephone / facsimile switching device of the present invention, after the line is connected, automatically discriminates whether or not the input signal from the calling side is the facsimile signal by the discriminating portion.
Meanwhile, the standby voice transmitting unit transmits a standby voice to the calling side, and notifies the calling side of the waiting by the identification of 1 to 2 seconds,
It reduces the waiting time of the conventional call on the calling side and saves the trouble of pressing the send button. In the case of a telephone, a ringing tone sounds and the call starts when the receiver hooks off. In the case of a facsimile, the facsimile signal is subsequently recorded in the recording unit, and the facsimile signal from the recording unit is reproduced as a transmission image when the transmission end signal is received.

[0014]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention, in which a switching unit 1, an identification unit 2, a recording unit 3, and a control unit 4 are provided.
The facsimile mechanism section 5, the standby voice transmitting section 6, and the telephone mechanism section 7. FIG. 2 is a timing chart when a facsimile is received, when a telephone call is made, and when the telephone is absent according to the present invention. FIG. 3 is a timing chart when a conventional facsimile is received, when a telephone call is made, and when the telephone is absent.

Three cases will be described with reference to the drawings, namely, when receiving a facsimile, when making a telephone call, and when not being on the telephone.

At the time of facsimile reception, the signal sent to the switching unit 1 is sent to the identification unit 2 when the sending side and the receiving side are connected.
Then, the data is sent to the recording unit 3 and the telephone and the facsimile are immediately identified. For only 1 to 2 seconds during identification, the standby voice transmitter 6 automatically sends a voice such as "please wait" or a chime sound for waiting to the caller side. When the control unit 4 receives that the identification result is a facsimile signal, the control unit 4 gives an instruction to sequentially send the facsimile signals input to the switching unit 1 to the recording unit 3. When a signal indicating the end of facsimile transmission is sent to the recording unit 3, the control unit 4 instructs the recording unit 3 to send all the recorded signals to the facsimile mechanism unit 5. The facsimile mechanism unit 5 reconstructs the transmitted facsimile signal into a transmission image and outputs it.

During a telephone call, the same as when receiving a facsimile is performed until the signal is identified. When the control unit 4 receives that the identification result is not a facsimile signal, the control unit 4
Gives an instruction to send signals input to the switching unit 1 to the telephone mechanism unit 7 one after another. The call begins after the ringing tone rings until the receiver goes off-hook.

Even when the user is absent from the telephone, after the ringing tone sounds as in the case of a telephone call, if there is an answering machine function, the telephone is switched to an answering machine. If you do not have an answering machine, the ringing tone will continue to ring.

[0020]

As described above, according to the present invention, since the telephone signal and the facsimile signal are automatically discriminated and the facsimile signal is automatically started to be transmitted, the waiting time on the calling side is short and the facsimile reception is performed. Sometimes the sending side saves the trouble of pressing the send button.

The shortened waiting time on the calling side is as follows for each of the three cases.

At the time of facsimile reception, the signal identification time in the present invention is subtracted from the standby voice transmission time in the prior art plus the time during which the ringing tone is sounded until the send button is pressed. The standby transmission time of the conventional technology is "If you are sending a fax, press the send button after the dial tone. Otherwise, please wait a while."
It takes about 10 seconds,
The ringing time is about 1 second. The identification time in the present invention can be regarded as about 1 second. Therefore, the time reduction during facsimile reception is "standby voice transmission time" + "call time"-"identification time" = 10 + 1-1 = 10 seconds.

At the time of receiving a telephone call, the identification time in the present invention is subtracted from the standby voice transmission time in the prior art, whether in a call or not. Therefore, the time reduction when receiving a call is "standby voice transmission time"-"identification time" = 10-1 = 9 seconds.

The above time reduction is greatly improved, and the waiting time can be almost ignored, so that there is an effect of eliminating the annoyance caused by the waiting time of the sender.
