Relays 9 and 10 are switched to the upper contacts in the figure during standby, and diodes 22 and 23 are connected by DC power supply 6.
and is pulled up to a predetermined voltage via resistors 13 and 14.

Further, a calling signal can be input from the ejection signal generating circuit 7 to either or both of the telephones 1 and 2 via the relays 11 and 12, so that a desired ringing bell sound can be sounded. When on standby, relays 11 and 12 are turned off and the telephone l
, 2 are disconnected from the telephone line 3 and supplied with power from a DC power supply 6.

When the ringing signal detection circuit 21 detects a ringing signal from the exchange at the time of receiving a call, the telephones 1 to 2 (
or both), and if the operator of either telephone 1 or 2 picks up the hook and answers,
This is detected by the hook state detection circuit 4.5, and the responding telephone is connected to the telephone line 3 by the relays 8 and 9, thereby making it possible to make a telephone call.

Relay control at the time of incoming call is controlled by a CPU 17 consisting of a microprocessor or the like. The CPU 17 also serves as a main control unit for the entire known facsimile machine including the facsimile communication circuit 15 and the like.

The control program for the CPU 17 is stored in the ROM 18,
Further, data such as image data and control parameters are stored in the RAM 19 as a work area.

The RAM 19 also stores a control flag for determining which bell of telephones 1 and 2 is to ring when a call is received, as well as registration data such as speed dial data. The stored contents of the RAM 19 are backed up by the backup power supply 25 even when the main power is off, such as during standby.

An operation section 24 consisting of a keyboard, a display, etc. is connected to the CPU 17 in order to input known operations such as facsimile communication control.

Each of the above-mentioned relays is controlled by the CPU 17 via the relay control section 20 according to control parameters stored in the RAM 19.

The control parameters according to the operation input from the operation unit 24 are
It is controlled by storing it in AM19.

You can select the ringing of the bell for telephones 1 and 2 as described above.
This selection differs depending on whether automatic switching between telephone/facsimile communication is to be performed when a call is received.

Figure 2 shows the control procedure when automatic switching between telephone and facsimile communication is not performed.
The incoming call control program of CPU I7 stored in OM18 is shown.

Step 5l-33 in FIG. 2 shows initial settings.

First, in step Sl, the operation of the operation unit 24 is read,
It is determined whether a predetermined operation has been performed to set the telephone to ring when a call is received.

If step SL is affirmed, the process moves to step S2, and in accordance with the operation of the operation unit 24, control parameters for setting the telephone to ring when a call is received are stored in the RAM 19.

In step S3, the relay 8 is connected to the ejection signal detection circuit 21 side, and the relays 9 and 1O are connected to the lines of the DC power supply 6 and the calling signal generation circuit 7 examples.

In step S4, the ejection signal detection circuit 21 detects a calling signal on the telephone line 3. If a ringing signal from the exchange is detected, the process advances to step S5. If no calling signal is detected, the process returns to step Sl.

In step S5, in step S6 set in step S2, relays 11 and 12 are
Turn on one of them.

In step S7, the ejection signal generating circuit 7 is driven to ring the bell of the telephone selected in steps S5 and S6 among the telephones 1 and 2.

In step S8, the hook state detection circuit 4.5 detects whether the hook of either telephone 1 or 2 is turned off. Hook-off is performed by detecting whether or not direct current from the DC power supply 6 has flowed to the line using the hook state detection circuits 4 and 5.

When the hook-off occurs, the ringing of the bell by the ringing signal generation circuit 7 is stopped in step S9, and either telephone 1 or 2 is connected to one of the three telephone lines via relays 9 and 10, and a call can be made in step SIO. becomes.

FIG. 3 shows a control procedure for automatic switching between telephone and facsimile communication.

The processing from step 541 onwards is step S1 in FIG.
This figure shows incoming call control in a mode in which automatic switching between telephone and facsimile communication is performed after S2.

In step S41, the relay 8 is connected to the upper side of the figure,
A call signal is detected by the ejection signal detection circuit 21.

When the discharge signal is detected, the relay 8 is connected to the lower side of the diagram in step S42, and the facsimile communication circuit 15 or DTMF signal detection circuit 1 is connected in step S43.

This detection processing is performed by detecting a voice band signal, a facsimile signal, a DTMF signal, or the like.

If step 343 is negative, step S4
At step 5, known facsimile communication is performed.

If step S43 is affirmative, step S44
In step 354 of FIG. 2, the same bell ringing control is carried out, and when telephone Ill, 2 answers, a call is made. In step S44 as well, only the telephone designated in advance by the operation unit 24 rings.

Which of the steps in Figure 2 or Figure 3 should be performed, that is,
Whether or not telephone/facsimile communication is to be automatically switched is set using the operation unit 24 according to a known procedure.

Note that when selecting a telephone to cause a bell to ring using the operation unit 24, it is preferable to configure the setting program so that settings for prohibiting the ringing of the bell of all telephones cannot be made.

According to the above configuration, when automatic switching between telephone and facsimile communications is performed, or even when automatic switching is not performed, when the telephone bell rings when a call arrives, only one of the plurality of telephones that is set will ring the bell. Can be done.

Therefore, it is possible to eliminate the annoyance of having the bell of the operator's machine ring when a call arrives.

Although a facsimile machine has been exemplified above, it goes without saying that the above configuration can be implemented with any communication device that is connected to a line together with a telephone.

Fig. 4 shows a modification of the process shown in Fig. 3. Here, in addition to detecting audio signals, CNG signals and DTMF signals are detected on received signals, and incoming calls are controlled according to the results. . In this case, the DTMF signal allows the calling party to control which telephone is to ring.

First, when an incoming call is detected in step S41 of FIG. 4, the relay 8 is connected to the facsimile side in step S42, and in step S46, whether the signal received by the line is a voice signal or
F signal or CNG indicating a non-voice terminal
Determine whether it is a signal. The received signal is DTM
If it is the F signal, it is determined in step S47 whether the received DTMF signal is "1" or "2", and if it is '1', the bell of telephone l is rung in steps S48 and S49, and the bell of telephone l is sounded. Wait for the hook to be turned off (operator's response), and in step S47 the DTMF signal is set to "2".
If so, in steps S50 and S51, ring the bell of telephone @2 and wait for the hook of telephone 2 to be turned off6.Furthermore, if the signal received in step 546 is a voice signal,
In steps S52, S53, and S54, step S in FIG.
5. Execute control similar to S6, S7, and S8. When the operator responds in step S49.551 or S54, the line is connected to the off-hook telephone in step S55, and a call is made in step 356.

If the received signal is a CNG signal at step 346, facsimile communication similar to step S45 in FIG. 3 is performed.

According to the above control, by detecting a CNG signal, if the other party is a facsimile device, it is possible to reliably switch to facsimile communication, and by communicating a DTMF signal, the calling side can also specify a telephone to ring. It has the advantage of being possible.

[Effects of the Invention] As is clear from the above, according to the present invention, in a communication device that is connected to a line together with a plurality of telephones and performs predetermined communication processing, when a call is received by the telephone, the plurality of telephones The system has a configuration that includes a control means for setting which bell to ring, so among the telephones connected to the line with the device,
You can select which phone rings the bell when you receive a call, and when you receive a call,
This has the excellent effect of making it possible to ring the bell of a telephone near the operator who handles the telephone, and eliminating the inconvenience caused by the ringing of the bell of a telephone unrelated to the operator who is taking the call, which was the case in the past.
