Abstract

PURPOSE:To allow an operator to recognize the destination of information received or to be received by a communication equipment by sending a prescribed control signal from a sender and outputting the information of prescribed form corresponding to a recipient. CONSTITUTION:When a facsimile equipment after a hybrid circuit receives a picture, to which operator of telephone sets 6, 8, 10, 12 the received picture is addressed is recognized, a corresponding telephone set is rung and the presence of facsimile incoming call is informed to the operator of the destination. In case of the presence of the facsimile incoming, the operator of the sender dials the telephone numbers (1-4) of the operator of the desired destination to ring the object telephone set and to inform the presence of facsimile incoming to the operator corresponding to the telephone set. When the destination operator replies, the telephone set only displays 'facsimile communication' to apply facsimile reception.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a communication device, and particularly to a communication device configured by connecting a terminal of a line with a number of telephones and a communication device that performs a communication operation of a predetermined method. It is related to the device.

[Prior Art] Conventionally, a technique has been proposed in which a calling party transmits a predetermined code to select one of a plurality of telephones to receive a call. This type of device allows the calling party to specify the desired person, which is more convenient than previous methods in which the operator of one of multiple telephones answers and switches telephones.

[Problems to be Solved by the Invention] However, in the above system, when a communication device such as a facsimile machine is connected with multiple telephones, all facsimile reception is performed by one connected device. , it was not possible to identify which of the multiple operators the image message was addressed to.

Therefore, when receiving a facsimile, it is necessary for one of the operators to collect the recording paper and distribute it to the recipient.

The above problem would be solved if all operators were given a facsimile machine or a facsimile machine integrated with a telephone, but even if many facsimile machines are connected to one line, they cannot communicate at the same time. This will force users to make excessive capital investments.

The above problem is the same even if the device connected to the telephone is not a facsimile device but a data terminal device or the like.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, more telephones than the number of lines and communication devices that perform communication operations of a predetermined method are connected to the line terminals. When transmitting information addressed to the operator of one of the plurality of telephones via the communication device, the transmitter sends a predetermined control signal to the receiver. A configuration is adopted in which information is output in a predetermined format to a telephone compatible with the communication device, and the operator is made to recognize the destination of the information received or to be received by the communication device.

[Operation 1] According to the above configuration, it is possible to easily identify to which operator the information is transmitted to the communication device.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 shows the structure of a communication system employing the present invention. The system is constructed by connecting a facsimile machine and four telephones numbered 1 to 4 6.8.1O112 to the telephone line 2a.

As shown, the phone! ! 2a is connected to NCU2. NCU2 has telephones 6.8.10.12 numbered 1 to 4 as voice terminals connected to signal lines 2c, 2d, 2e, 2.
It is connected via f. As a non-voice terminal, a facsimile communication system after the hybrid circuit is connected via the signal line 2g.

The facsimile machine after the hybrid circuit is configured as follows.

First, the hybrid circuit 14 connected to the NCU 2 via the signal line 2g is used to separate transmitted and received signals. The transmitted signal is inputted from the signal @ 24 a, and the received signal is outputted via the signal line 14 a. The transmission system is composed of an adder circuit 24, modulators 20, 22, encoding circuit 18, and reading circuit 16.

Addition circuit 24 connects signal lines 20a, 2 from modulator 20.22.
This is for adding the image signal or facsimile procedure signal input via 2a.

The procedure signal is input to the modulator 22 by the control circuit 34 via the signal line 34b. Modulator 22 complies with CCITT Recommendation V
The transmission procedure signal inputted from the control unit 34 is modulated using a modulation method that conforms to the standard 21.

The image signal is read by a reading circuit 16 consisting of a CCD line sensor or the like, and compressed by an encoding circuit 18 using an MH or MR encoding method. After that, CCIT
Modulator 20 compliant with T recommendation V27ter or V29
and is input to the adder circuit 20a.

On the other hand, the demodulator 26 connected to the signal line 14a is connected to the CCIT
The received procedure signal is demodulated using a demodulation method that complies with T Recommendation V21. The demodulated procedure signal is input to the control section via the signal line 26a.

Further, the image signal is demodulated by a demodulator 28 having a demodulation method corresponding to the modulator 20, and is input to a decoding circuit 30 via a signal line 28a. The decoding circuit 30 corresponds to the encoding circuit 18 described above, and converts compressed data back into raw binary data. The converted data is input to a recording circuit 32 made up of a thermal printer or the like via a signal line 30a, and is recorded.

Among these signal lines, signal lines 6a, 8a, 10a, 1
Reference numerals 2a and 2a each provide a signal indicating the hook state of the telephone to the control unit 34. These signal lines depend on the hook status of each phone, and are set to level “0” in the on-footer status.
”, and the level is “1” in the off footer.

Further, two signal lines heading toward the telephone set are control signals for the display DP provided in each telephone set and control signals for the ring tone generating circuit of the telephone set. These signals are labeled 34c
and 34d, 34d and 34e, . . . 34i and 34j. Among these signal lines, the one with the lowest alphabet is for ring tone control,
The remaining one is for display control.

For example, in the case of the telephone 6, the signal line 34c is at level "1".
”, the bell of the telephone 6 rings and the level is “O”.
In this case, ringing of the bell is prohibited. In addition, the signal line 34
When d is level "1", it is displayed on the display DP, and when it is level "O", display on the display DP is prohibited. This configuration is common to each telephone.

The display device DP is constituted by an LED, an I, a CD, a lamp circuit, or the like, and outputs a display such as "Facsimile communication in progress" when driven through the signal line. Further, this display is stopped when controlled to a non-driving state.

In this embodiment, when the facsimile device after the hybrid circuit is receiving an image, it recognizes which operator of the telephone 6.8.10.12 the received image is addressed to, and The corresponding telephone will ring and the destination operator will be notified of the incoming facsimile call.

Next, the control procedure of the control circuit 34 that enables the above operation will be explained in detail. FIG. 2 shows the communication procedure of the control circuit 34 of FIG. 1. The procedure shown in FIG. 2 is stored in the ROM 34r as a control program for the control circuit 34.

With the above procedure, when a facsimile call is received, the operator on the sending side can
By dialing 4), the target telephone rings and the operator corresponding to the telephone is notified of the incoming facsimile call. When the destination operator responds, only that telephone displays "Facsimile communication in progress" and receives the facsimile.

If the sender does not specify a telephone, or if the operator of the telephone that made the call does not answer, the display of all telephones displays "Facsimile communication in progress", Receive faxes as expected.

By performing the above-described control, it is possible to specify the destination for facsimile reception in a system including a plurality of telephones and facsimile machines. Therefore, there is no need for an unrelated operator to receive the received document and distribute it to the addressee, as is the case in the past, and work using facsimile can be facilitated.

In the above, information regarding the destination of facsimile communication is output by the ringing of the telephone's bell circuit or by display output, but the information may be output by other means, such as an audio signal formed by a voice synthesis means or the like.

Further, in the embodiment described above, all telephones are made to ring when no destination is specified by the sender, but the processing in this case is not limited to this. For example, if the telephone/facsimile changeover switch 33 is set on the telephone side, only one predetermined telephone may ring.

Further, in the above embodiments, a facsimile machine is used as an example of a communication device, but the present invention is not limited to this, and various communication devices such as a data terminal can be used in combination with a telephone.
