In addition to a dedicated telephone (hereinafter, referred to as a built-in telephone), a telephone for general calls (hereinafter, referred to as an attached telephone) and a facsimile device with a telephone that can be connected in parallel to the outside.

(Prior Art) Generally, a facsimile transmitter / receiver is selectively connected to a built-in telephone and an attached telephone via a network control unit (hereinafter abbreviated as NCU) to a communication path such as a telephone line. Has become. That is, when the telephone is used by the operation of the NCU, the telephone is switched and the facsimile transmitter / receiver is switched and connected to the telephone line when transmitting / receiving the facsimile. At this time, the other is disconnected from the telephone line. ing.

FIG. 2 shows an electrical configuration of such a conventional facsimile apparatus with a telephone.

In the figure, 21 is a telephone line, 22 is an NCU, 23 is a facsimile transceiver, 24 is an operation panel, and 25 is a main controller. The main control unit 25 is composed of operation panel detection means 25a, facsimile transmitter / receiver drive means 25b, incoming call detection means 25c, line switching drive means 25d, and the like. Further, 26 is a built-in telephone, 26a is a handset, 27 is an incoming call detection circuit, and 28 is an attached telephone.

That is, in the standby state where the facsimile transceiver 23 is not operating, the telephone line 21 is connected to the telephone side (c terminal side) by the NCU 22, and the facsimile transceiver 23 is disconnected from the telephone line 21. Therefore,
From this state, it is possible to make a call and make a call using the built-in telephone set 26, or to make and make a call using the auxiliary telephone set 28. Further, since the incoming call bells of both the built-in telephone set 26 and the auxiliary telephone set 28 ring at the time of incoming call, it is possible to answer the incoming call with any of the telephone sets.

On the other hand, when performing a facsimile transmission from this state, first, the telephone line 21 is captured by an operation such as raising the handset 26a of the built-in telephone 26, and the destination telephone number (in this case, the facsimile number) is dialed. Establishes a communication path with the destination. After that, the facsimile transmission / reception unit 23 is activated from the operation panel 24 via the main control unit 25, the NCU 22 is switched to the b terminal side, the telephone line 21 is switched to the facsimile transmission / reception unit 23 side, and then the facsimile transmission / reception is performed by a predetermined procedure. Send. After the facsimile transmission is started, the built-in telephone set 26 and the attached telephone set 28 are disconnected from the telephone line 21, so that the built-in telephone set 26 and the attached telephone set 28 both become silent even when the handset is lifted and cannot be used. Note that in a facsimile machine with a telephone having an automatic transmission / reception function, capturing of the telephone line 21, dialing of a telephone number, and switching of the telephone line 21 to the facsimile transmitter / receiver side may be performed automatically.

Further, when performing facsimile reception, the bell of the built-in telephone 26 will ring at the time of incoming call. Therefore, if a facsimile reception request is made by responding to the incoming call by an operation such as lifting the handset 26a, the main control unit 25 is operated from the operation panel 24. The facsimile transmitter / receiver 23 is activated via this, the NCU 22 is switched to the terminal b side, the telephone line 21 is switched to the side of the facsimile transmitter / receiver 23, and then the facsimile is received by a predetermined procedure. After the facsimile reception is started, the built-in telephone set 26 and the attached telephone set 28 are disconnected from the telephone line 21, so that the built-in telephone set 26 and the attached telephone set 28 both become silent even when the handsets are lifted and cannot be used. In a facsimile machine with a telephone having an automatic transmission / reception function, after an incoming call is detected by the incoming call detection circuit 27, the response to the incoming call and the switching of the telephone line 21 to the facsimile transceiver 23 side are automatically performed. There is a case to be seen.

(Problems to be Solved by the Invention) However, in such a conventional facsimile apparatus with a telephone, since the built-in telephone 26 and the attached telephone 28 are disconnected from the telephone line 21 during the facsimile transmission / reception operation, any telephone No sound is heard even when the handset is off-hook, and there is no sound. Therefore, there is a problem that the operator of the telephone is anxious as if the telephone is not operating normally. In particular, in the case of an attached telephone that is installed as a telephone for ease of use, it is often installed in a place away from the facsimile machine, so it is possible to immediately determine whether the facsimile machine is operating. It was very inconvenient.

(Means for Solving the Problems) In order to solve the above problems, in a facsimile apparatus with a telephone of the present invention, a side-by-side telephone and a built-in telephone that mainly establishes a communication path for facsimile transmission / reception are connected in parallel. A telephone line connected to a facsimile transmitter / receiver, which is normally connected to an outside line, is connected to the built-in telephone and the attached telephone which are connected in parallel, and during facsimile transmission / reception, the connection is switched to the facsimile transmitter / receiver side by the line switching drive means. Applicable to a facsimile machine with a telephone equipped with a network control device, an audible sound generating circuit that generates an audible sound based on an off-hook detection signal, and the output of this audible sound generating circuit to the built-in telephone and the attached telephone connected in parallel. Connection switch for connecting to the telephone line of the A hook detection circuit that outputs the off-hook detection signal to the audible sound generation circuit when a hook is detected, the connection switch interlocking with switching control of the network control device by the line switching drive means, When the connection of the network control device is switched to the side of the facsimile transmitter / receiver, it is switched from the off state to the on state, and when it is switched to the side of the built-in telephone and the attached telephone, it is switched from the on state to the off state.

(Operation) The line switching drive means switches ON / OFF of the connection switch so as to interlock with the switching control of the network control device.
That is, the connection switch is switched from the off state to the on state when the connection of the network control device is switched to the facsimile transmitter / receiver side, and the connection switch is turned on when the connection of the network control device is switched to the built-in telephone and the side-mounted telephone side connected in parallel. To the off state.

As a result, the connection switch is turned on during facsimile transmission / reception. When the telephone is off-hook in this state, the hook detection circuit detects this and outputs an off-hook detection signal to the audible sound generation circuit. The audible sound generation circuit is driven by the off-hook detection signal, and sends audible sounds such as busy tone and voice to the respective handsets of the built-in telephone and the attached telephone via the connection switch.

In other words, the line switching drive means has a simple circuit configuration in which the connection switch is turned on / off in conjunction with the switching control of the network control device, and also through the conventional call circuit, each handset of the built-in telephone and the attached telephone An audible sound indicating that the facsimile transceiver is in operation can be transmitted from (especially, the handset of the attached telephone).

In addition, since the built-in telephone and the attached telephone are connected in parallel, when one user uses the attached telephone to make an external call, another user off-hooks the built-in telephone in order to perform facsimile transmission. Since the voice is heard, the user of the built-in telephone can know that the attached telephone is in use. Therefore, a user who off-hooks the built-in telephone while using the side-by-side telephone will not misunderstand that the built-in telephone is out of order and cannot be used.

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic block diagram showing an electrical configuration of a facsimile machine with a telephone of the present invention.

In the figure, 1 is a facsimile machine with a telephone, 2 is a side-by-side telephone, 3 is a telephone line connected to a telephone station (not shown), 4 is a facsimile transceiver for transmitting and receiving images, and 5 is this facsimile transceiver. Built-in telephone installed in (or adjacent to) the same housing as 4; 5a, handset of built-in telephone 5; 6; incoming call detection circuit for telephone; 7; telephone line 3 for facsimile transceiver 4 side and built-in telephone 5, a network control unit (hereinafter, abbreviated as NCU) that is switched to and connected to the side telephone 2 side, 8 is an operation panel for a user to operate the apparatus, and 9 is an operation of the facsimile transceiver 4. A main control unit 10 is an audible sound generating unit that generates an audible sound during a facsimile transmission / reception operation. The main control section 9 detects an operation state of the operation panel 8 and gives a signal to each section, an operation panel detection means 9a, a line switching drive means 9b for driving the NCU 7 according to an operation state of the facsimile apparatus 1 with a telephone, and a facsimile transceiver. 4 is composed of a facsimile transmitter / receiver driving means 9c for controlling the operation of No. 4 and an incoming call detecting means 9d for receiving a signal from the incoming call detecting circuit 6. In addition, the audible sound generation unit 10 is separated from the audible sound generation circuit 10a and the telephone line 3 that generate a busy tone by a 400 Hz intermittent signal or a voice such as "I am currently transmitting (or receiving) a facsimile". A DC voltage supply circuit 10b for supplying a voltage between them, a hook detection circuit 10c for detecting a hook state, that is, an ON / OFF state of a handset, and an output of an audible sound generation circuit 10a when the telephone is off-hook, the built-in telephone 5
And a connection switch 10d for connecting to the side-mounted telephone 2.

The connection switch 10d is adapted to be switched between an on / off state in synchronization with the switching control of the NCU 7 by a signal from the line switching drive means 9b. That is, when the connection of the NCU 7 is switched to the side of the facsimile transceiver 4, the connection switch 10d is switched from the off state to the on state, and when the connection of the NCU 7 is switched to the built-in telephone 5 and the side telephone 2 side, the connection switch 10d is It is designed to switch from the on state to the off state.

Next, the operation of the facsimile machine with a telephone having the above configuration will be described.

First, in the standby state where the facsimile transceiver 4 is not operating, the telephone line 3 is connected to the telephone side (c terminal side) by the line switching relay in the NCU 7.
The facsimile transceiver 4 is disconnected from the telephone line 3. Therefore, from this state, it is possible to make a call and make a call using the built-in telephone 5, or to make and make a call using the side-by-side telephone 2. Further, since the incoming call bells of both the built-in telephone 5 and the side-by-side telephone 2 ring when an incoming call is received, it is possible to answer the incoming call with either telephone.

On the other hand, when performing facsimile transmission from this state, first, the telephone line 3 is captured by an operation such as raising the handset 5a of the built-in telephone 5, and the destination telephone number (in this case, the facsimile number) is dialed. Establishes a communication path with the destination. Then, when the facsimile start key of the operation panel 8 is pressed, the operation panel detection means 9a in the main control section 9 detects this and outputs this detection signal to the line switching drive means 9b and the facsimile transceiver drive means 9c. To do. Receiving this signal, the line switching drive means 9b outputs a switching signal to the NCU 7, connects the telephone line 3 to the facsimile transceiver 4 side (b terminal side), and outputs a signal to the connection switch 10d of the audible sound generating section 10. It outputs and turns on the connection switch 10d. Further, the facsimile transceiver driving means 9c receives a signal from the operation panel detecting means 9a and outputs a transmission operation signal to the facsimile transceiver 4,
The facsimile transmitter / receiver 4 is set to the transmitting operation state. Then, the facsimile is transmitted according to a predetermined procedure. On the other hand, since the connection switch 10d of the audible sound generating section 10 is turned on by the signal from the line switching driving means 9b, the built-in telephone 5 and the attached telephone 2 are connected to the audible sound generating circuit 10a via the DC voltage supply circuit 10b. To be done. Therefore, when the handset of the built-in telephone set 5 or the side-by-side telephone set 2 is hooked off, the hook detection circuit 10c detects this and outputs an off-hook detection signal to the audible sound generation circuit 10a. The audible sound generation circuit 10a is driven by this off-hook detection signal, and audible sounds such as busy tone and voice are output from the handset 5a of the built-in telephone 5 or the handset of the auxiliary telephone 2. Thereby, the operator can easily confirm that the facsimile transceiver 4 is operating. In a facsimile machine with a telephone having an automatic transmission / reception function, capturing of the telephone line 3, dialing of a telephone number, and switching of the telephone line 3 to the facsimile transmitter / receiver side may be automatically performed.

In addition, when receiving a facsimile, the bell of the telephone rings at the time of the incoming call. Therefore, by answering the incoming call by an operation such as lifting the handset, and if there is a request for facsimile reception, the facsimile start key on the operation panel 8 is pressed. The operation panel detection means 9a in the control section 9 detects this and outputs the detection signal to the line switching drive means 9b and the facsimile transceiver drive means 9c. Receiving this signal, the line switching drive means 9b outputs a switching signal to the NCU 7, connects the telephone line 3 to the facsimile transceiver 4 side (b terminal side), and outputs a signal to the connection switch 10d of the audible sound generating section 10. It outputs and turns on the connection switch 10d. Further, the facsimile transceiver driving means 9c receives a signal from the operation panel detecting means 9a and outputs a reception operation signal to the facsimile transceiver 4 to bring the facsimile transceiver 4 into a reception operation state. Then, the facsimile is received according to a predetermined procedure. On the other hand, since the connection switch 10d of the audible sound generating section 10 is turned on by the signal from the line switching driving means 9b, the built-in telephone 5 and the attached telephone 2 are connected to the audible sound generating circuit 10a via the DC voltage supply circuit 10b. To be done. Therefore, when the receivers of the built-in telephone 5 and the side-by-side telephone 2 are off-hooked, the hook detection circuit 10c detects this and outputs an off-hook detection signal to the audible sound generation circuit 10a. The audible sound generation circuit 10a is driven by this off-hook detection signal, and audible sounds such as busy tone and voice are output from the handset 5a of the built-in telephone 5 or the handset of the auxiliary telephone 2. Thereby, the operator can easily confirm that the facsimile transceiver 4 is operating. In addition, in the facsimile machine with a telephone having the automatic transmission / reception function, the incoming call detection circuit 6
In some cases, after the incoming call is detected in step 1, the incoming call is answered and the telephone line 3 is switched to the facsimile transceiver 4 side.

As described above, in the facsimile apparatus with a telephone of the present invention, when the receiver of the built-in telephone 5 or the side-by-side telephone 2 is off-hook while the facsimile transceiver 4 is operating, the speaker of the receiver informs that the facsimile transceiver 4 is operating. An audible sound can be sent.

Further, since the built-in telephone 5 and the attached telephone 2 are connected in parallel, when one user uses the attached telephone 2 to make an external call, another user off-hooks the built-in telephone 5 to perform facsimile transmission. Since the voice during the call is heard, the user of the built-in telephone 5 can know that the auxiliary telephone 2 is in use. Therefore, there is no concern that a user who off-hooks the built-in telephone 5 while using the side-by-side telephone 2 will misunderstand that the built-in telephone 5 cannot be used due to a failure.

(Effects of the Invention) As described above, according to the facsimile apparatus with a telephone of the present invention, when the handset is off-hook while the facsimile transceiver is operating, an audible sound notifying that the facsimile transceiver is operating is generated from the handset. I can hear you
Unlike the conventional device, the operator does not feel anxiety as if the telephone is out of order. In addition, when a telephone with a telephone is installed at a place distant from the facsimile machine with a telephone, it is not necessary to come to the place with the facsimile machine with a telephone to check whether the facsimile transceiver is operating. Usability is also improved. Furthermore, with the line switching drive circuit, a simple circuit configuration is provided in which the connection switch is switched on / off in conjunction with the switching control of the network control device.
In addition, since the audible sound is transmitted from each handset of the built-in telephone and the attached telephone through the conventional call circuit, the facsimile transceiver is operating without adding any circuit to the built-in telephone and the attached telephone. This can be surely transmitted to the built-in telephone and the side-mounted telephone.
