Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine in which one line is shared by a telephone and a facsimile machine.

(Prior Art) Recently, with the spread of facsimile machines, the number of stations sharing one telephone line between a telephone and a facsimile machine has increased.

However, when such a shared station is a receiving station, depending on whether the line is connected to a telephone or a facsimile machine, communication may not be possible even if a telephone call is made, or facsimile communication may not be possible.

Therefore, conventionally, a facsimile apparatus which is provided with a means for monitoring a line and a switching means for connecting the line to a facsimile device after monitoring for a predetermined period of time to enable selective switching between telephone communication and facsimile communication. There is. When there is a call (ringing) from the line, this facsimile machine connects the line by the switching means and monitors the line for a predetermined time (for example, 10 seconds). When the other party is a telephone, the voice signal from the other party is output as voice to the outside, and when this operator picks up the receiver by this monitor, the switching means connects the line to the telephone and communicates by telephone. It can be carried out. If the partner station is a facsimile machine, voice output cannot be obtained depending on the monitor, so the receiving operator does not pick up the handset. The switching means connects the line to the facsimile machine after a predetermined time for monitoring has passed, and the facsimile machine sends out a called station identification signal (CED). Therefore, by monitoring the line, it is possible to know that it is a communication by telephone, it is possible to communicate by telephone by picking up the handset, and by not taking the handset, the line is automatically set to the facsimile machine. It can be switched, and facsimile communication can be surely performed.

However, in such a conventional facsimile apparatus, if the receiving side operator is not near the telephone when the other side is a telephone, the line cannot answer the call of the other side by the monitor, and the other side The operator is connected to the line but remains silent without a response for a predetermined period of time, after which a CED signal beep is returned. Such a situation is
Since it is different from normal telephone communication, there is a problem in that telephone communication cannot be performed because the user cannot understand and feels discomfort and disconnects the line before or after a predetermined time has elapsed.
Also, when the partner station is a facsimile machine, it must wait for a predetermined time for monitoring for a predetermined time for monitoring until the facsimile communication becomes possible, which requires extra time and communication cost. There was a problem.

(Object of the Invention) Therefore, according to the present invention, a facsimile communication is performed by connecting a line to a facsimile apparatus and notifying a call to the other side by voice that the line is connected to the facsimile apparatus and then sending a control signal. , Or by emitting a ringing tone for a predetermined period of time, the operator of the other party is informed of the state of his / her own station, and the telephone device and the facsimile device are automatically switched without providing unnecessary waiting time. In the case of telephone communication, the purpose is to call the local operator without giving anxiety or discomfort to the other operator, and in the case of facsimile communication, reduce the communication cost and reliably receive information. I am trying.

(Structure of the Invention) In order to achieve the above object, the present invention provides a network control device for controlling connection with a facsimile device on the other side in a facsimile device that shares one line with a telephone set.

A controller (24) for controlling RY1),
When the ringing signal from the line is detected, the controller (24) includes the relay (RY
1) The line is connected to the network control device (21) and the voice generating device (22) is activated to output a voice message indicating that the line is connected to the network control device (21). When the facsimile procedure signal is sent from the other party after sending, the facsimile communication is started, while when the facsimile procedure signal is not sent from the other party, the ring tone generator (25) is activated to call. Sound is emitted to the outside for a predetermined time, and if the telephone is off-hook while the ringing tone is ringing, the relay (RY1) switches the line to the telephone and connects, while within the predetermined time. When the telephone is not hooked off, the voice generating device (22) executes control to send a voice message indicating that the receiving side is absent to the other side.

The frequency detection device 23 detects the response signal transmitted from the facsimile machine of the other party, and the ring tone generator.
25 generates a ringing tone for informing that a call is being made, according to a command from the controller 24. The voice generation device 22 has a voice LSI, a ROM, and the like, and selects and outputs an appropriate voice according to a command from the controller 24 from voice data input in the ROM in advance. The network control device 21 is a network control device of at least an automatic incoming call type, which controls connection with the facsimile machine 1 on the other side through an external circuit according to a control signal.

Next, the operation will be described.

As described above, the facsimile device 1 shares one line with the telephone set, and normally the line is connected to the telephone set. That is, in FIG. 2, the common terminal c of the relay RY1 is normally connected to the break terminal b. If there is ringing in this state, the ring detector 28 detects the ring and outputs a signal notifying the controller 24 of the ring detection. When the ring detector 28 detects a ring, the controller 24 switches the relay RY1 to connect the line to the network controller 2
When the line is connected to 1, the voice output device 22 sends a voice output to the line, and the line is connected to the facsimile device, so that the user is requested to wait until calling. Then
After sending the called station identification signal (CED signal) from the network controller 21, a digital identification signal (DIS signal), and sometimes a non-standard function signal (NSF signal), a called party identification signal (CSI signal), a non-standard Function command signal (NSC signal), calling terminal identification signal (CIG signal), digital transmission command signal (DTC signal)
Send the control signal of the procedure shown in CCITT recommendation. When a response signal from the partner station to this control signal, for example, a digital command signal (DCS signal) or a digital transmission command signal (DTC signal) is input, the response signal is detected by the frequency detection device 23, When the normal facsimile communication is started and there is no response signal, the ringing tone generator 25 is operated to generate a ringing tone, and the relay RY2 is turned on to connect the DC power supply 27 to the telephone. When the operator picks up the telephone receiver for this ringing tone, the telephone and DC power supply
A closed loop is formed between 27, the current detector 26 and the relay RY2, and a DC current flows from the DC power supply 27. When the current detector 26 detects this DC current, the controller 24 turns off the relay RY2 and then switches the relay RY1 to connect the common terminal c to the break terminal b. This connects the line to the telephone and enables telephone communication. Further, when the handset is not picked up even after the ringing tone is continued for a predetermined time, the voice generating device 22 outputs a voice output to the line to notify that the operator is absent. After that, a disconnection command signal (DCN signal) is sent to disconnect the line.

The above operation (this operation is the control executed by the controller 24) can be represented as shown in FIG. 3 by a flowchart. That is, in Step P _1, upon detecting a ring, at step P _2, it switches the line to a network control unit 21, waiting in step P _3, to call because the line by sending the audio output is connected to the facsimile device Notify you By this voice notification, even when the partner station is a telephone, the partner operator can be allowed to wait for a response without giving anxiety or discomfort to the partner operator. In Step P _4, a CED signal, in step P _5, DIS
Signals (NSF, CSI, NSC, CIG, DTC signals) are transmitted, and in step P ₆ , it is determined whether or not a response signal from the partner station has been received. Upon receiving the response, performs normal facsimile communication at step P _7, in step P _8, the line is disconnected. If no response signal is received in step P ₆ , it is determined in step P ₉ whether the DIS signal or the like has been transmitted three times,
Repeat until sent three times. If there is no response 3 out forwards the DIS signal, etc., it is determined that the other station is not a facsimile apparatus, in step P _10, and sends the ringing tone. That is, first, since it is determined whether or not the partner station is a facsimile machine, facsimile communication can be started without waiting for an unnecessary waiting time, and communication costs can be reduced. In addition, since it takes only a short time to repeat the transmission of the DIS signal and the like three times, a ringing tone can be promptly generated in the case of telephone communication. In step P ₁₁ , it is determined whether or not the handset is picked up, and when it is picked up, in step P ₁₂ , the line is connected to the telephone and in step P ₁₃ ,
Move to telephone communication. Therefore, it is possible to call the operator of the own station and make a telephone call in a short time without giving the operator of the other station anxiety or discomfort. When the handset is not picked up in step P ₁₁ , a predetermined time (a time sufficient for calling the operator of the own station, for example, 20 ± 5 seconds, which can be set as appropriate) has elapsed in step P ₁₄ . and discriminates whether or not, when the predetermined time has elapsed, in step P _15, and notifies that operator is absent by sending audio output. Thereafter, in step P _16, D
It sends a CN signal, in step P _8, the line is disconnected. Therefore, even when the operator of the local station is absent, the line is disconnected without giving anxiety or discomfort by disconnecting the line without answering the other operator, and without giving unnecessary waiting time to the other operator. Can be cut.

(Effect) According to the present invention, it is possible to notify the operator of the other party of the status of the own station, and it is possible to automatically switch between the telephone device and the facsimile device without providing an unnecessary long waiting time. In the case of telephone communication, the operator at the local station can be called without causing anxiety or discomfort to the operator at the other end, and in the case of facsimile communication, information can be received reliably while reducing communication costs. You can
