Abstract

PURPOSE:To attain voice communication immediately when an opposite party desires voice communication by providing a means detecting a transmission energy over a setting level of a signal such as a voice signal or a DTMF signal. CONSTITUTION:A receiver receiving a call signal 1 from a caller device sends a prescribed reply message 2 to a caller device and sends succeedingly a line connection signal 3 and a digital identification signal 4. Thus, when a hand- shake tone signal is sent, the receiver connects the reception function to facsimile communication. On the other hand, when a human voice or a DTMF signal is sent, the receiver inputs the energy 5 to the control circuit, where a CPU 6 calculates the energy. When the energy is larger than a prescribed value, the receiver connects the call to a telephone set or a recorder 9.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a reception switching method in a facsimile machine with an answering machine function.

[Conventional technology]

Facsimile machine with 9 tone function as an answering machine
ff has been used conventionally. This device usually prioritizes input to the facsimile device, which is its main function, and functions as a conversation or answering machine only after a signal that is not sent to the facsimile device is confirmed. was. FIG. 4 is a block diagram showing the reception switching method of a conventional device. When a call signal from a calling device is input to a receiving device, a response message is sent from the receiving device to the calling device, and then the line connection signal. A digital identification signal is transmitted from the receiving device to the originating device. In the case of facsimile transmission, the sending device transmits a digital command signal, and the receiving device waits for facsimile reception. If the calling device is using a telephone for conversation with the receiving device, no digital command signal will be transmitted from the calling device to the receiving device, and the telephone will remain silent. FIG. 4 shows this state. If the receiving device does not receive a signal from the transmitting device, it will transmit the digital identification signal again, and if there is no sound, it will transmit the digital identification signal again. In this way, the receiving device sends a digital identification signal to the sending device several times in response to a non-response, confirms that it is not a facsimile transmission, and then rings the receiving device's ringer. It had been. [Problems to be Solved by the Invention K] The reception switching method employed in conventional facsimile machines with an answering machine function is such that after a digital signal is transmitted from the receiving device, a digital command signal as a facsimile is sent from the transmitting device. If not entered into the receiving device, a digital signal was sent from the receiving device to the sending device several times to confirm that the transmission was not a facsimile. With the reception switching method of such conventional devices, if the user on the sending side wishes to record a conversation or business, he or she must wait for a considerable period of time before connecting to the other party's telephone line. There was a problem that it didn't work. The present invention relates to a reception switching system in a facsimile machine with an answering machine function, which aims to solve the above-mentioned problems.

[Means to solve the problem]

After transmitting the line connection signal and digital identification signal to the originating side, the modem on the receiving side and the central processing yI! When a signal from the transmitting side is input to the control circuit made up of device A, and the transmission energy exceeds the set level, such as a human voice or a pulse signal from a push button, it rings the line's receiving intelligibility. , or connected to an absentee recording device. K-Function] When a call @ sign is input from the calling device to the receiving device, a response message is transmitted from the receiving device to the calling device. Then, the receiving device transmits the f@receiving device line connection signal and the f digital identification signal, and the transmitting device that receives these signals sends a digital command signal to the receiving device if it is a facsimile transmission. is sent. The receiving device receives the digital command signal from the transmitting device and performs facsimile reception according to a predetermined procedure. On the other hand, when a signal such as a human voice or a pulse signal caused by pressing a push button is transmitted from the optical signal side device, the receiving side device inputs this input signal to the energy detection circuit and compares it with the set level. do. When it is confirmed that the input signal exceeds the set level, the connection is immediately switched to an answering machine or a ringer call line.

【Example】

The reception switching method in the facsimile machine with answering machine function of the present invention will be explained based on its implementation circuit. Figure 1 shows that after receiving a calling signal from the calling device,
FIG. 2 is a block diagram showing the circuitry of the receiving device until the receiving line is switched between a facsimile function, an answering machine, and a ring-calling device. 1ζ receives a calling signal 1 from a calling device (not shown);
The receiving device transmits a predetermined response message 2 to the transmitting device, and then transmits a line connection signal (CED) 3 and a digital identification signal (Dis) 4. There is nothing different about the equipment. A handshake tone signal is transmitted from the originating device that has received the signal, and when the receiving device receives this handshake tone signal, it connects the receiving function to facsimile communication. Handshake text from this calling device
The vI function of the receiving side apparatus for facsimile reception in response to the facsimile signal is also the same as that of the conventional apparatus. The signal from the calling device is not a handshake tone, but a human voice,
Alternatively, if the energy 5 is a pulse signal generated by a push button, the receiving device inputs the transmitted energy 5 from the transmitting device to the control circuit. FIG. 2 is a block diagram showing this control circuit. Transmission energy such as voice is input to an energy detection circuit formed by a central processing unit (CPU) 6 and a modem 7. In the energy detection circuit, the modem 7 calculates the transmission energy and sends it to the central processing unit 6 as a corresponding numerical value. The central processing unit 6 averages the values for 0.5 to 1 second, and when this average value is higher than the set level, it determines that it is a human voice or the like. If the absence changeover switch on the operation panel 8 of the receiving device is set for absence recording, the recording device 9 is connected to record the absence recording. On the other hand, if the answer switch is set for telephone use,
Connect to Ringer Call and ring your phone. If the telephone receiver is not picked up even after ringing the bell for a certain period of time, the telephone is connected to the recording device 9 for recording when the telephone is away. In the block diagram of the control circuit shown in FIG. 2, I/F is an interface, ROM is a read-only storage device, RAM is a random access storage device, and NCU is a network control device. Next, the reception switching method in the facsimile machine with answering machine function of the present invention will be explained based on the flowchart shown in FIG. When the receiving device receives transmitted energy 5, such as a human voice or a pulse signal from a push button, from the transmitting device, a response message 2 is transmitted from the receiving device to the transmitting device in step 1. In step 2, a line connection signal is transmitted from the receiving device to the transmitting device. In step 3, a digital identification signal is transmitted from the receiving device to the transmitting device. Handshake from the sending device to the receiving device in step 4!・The presence or absence of the -on signal is determined. Step 5 connects the line to facsimile reception when a handshake tone signal is received. Step 6 is when there is no handshake tone signal,
Transmission energy from the transmitting device to the receiving device is input to the control circuit, and when the transmitted energy does not reach a set level, a digital identification signal is transmitted from the receiving device to the transmitting device. Step 7 is when the control circuit detects transmission energy exceeding a set level, it determines whether the changeover switch is set for recording when the user is away, and if it is set for recording when the user is away, the connection is made to the recording device. . Step 8 makes a ringer call when the selector switch is set to telephone ring. In step 9, the ringing continues for a certain period of time m, and it is determined whether or not there is a response. In step 1o, depending on the call level, the receiver is picked up and a conversation takes place, and in step 11, it is determined that the person is not present, and the connection is made to the recording device. The switching process for one call ends with each of the above steps.

【Effect of the invention】

In the reception switching method of the facsimile machine with answering machine function of the present invention, a calling signal from the calling device is received by the receiving device, and the receiving device sends a response message, a line connection signal, and an f-digital identification signal to the calling device. After sending a message, it is immediately determined whether it is a facsimile communication or a recorded or conversational communication based on the signal sent from the optical communication side device, and the switch is made, so facsimile communication can be started immediately by connecting the line. This is the same as before, and recording of an answering machine or ringer call can be performed in almost the same way as facsimile communication, which is extremely useful. Also, special for adopting this method! 1
