Abstract

PURPOSE:To call a key telephone system even after a response is automatically executed to the incoming call of a line wire by the terminal of an automatic answering telephone set and to enable a call between the key telephone system and line wire by receiving the command of a PB signal to be sent from the line wire and sending a sound message, which is recorded in advance, to the key telephone system of an extension. CONSTITUTION:The command of the PB signal to be sent from a line wire 6 is received by a PB receiver 2-1 in an automatic answering terminal 2 and the message, which is recorded to a recording and reproducing circuit 2-3, is sent through a bus 5 for extension call and data transmission/reception to a communication circuit 3-1 in key telephone systems (1-N) and loudly spoken by a speaker 3-6. At such a time, by setting the off-hook of a hand set 3-7 in one key telephone system, the automatic answering terminal 2 releases the line wire 6 and the off-hooked key telephone system catches the line wire 6. Thus, even after the response is automatically executed to the incoming call of the line wire by the terminal 2 of automatic answering telephone set, the key telephone system can be called and operation can ber switched to the call between the key telephone system and line wire.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a button telephone device, and in particular, a button telephone device that automatically answers an incoming call from an outside line and can record and play back the voice signal sent from the outside line. The present invention relates to a button telephone device that accommodates an answering machine.

[Conventional technology]

Conventionally, an answering machine housed in this type of key telephone device is configured to automatically answer an incoming call from an outside line, and to record and play back a voice signal sent from the outside line.

[Problem to be solved by the invention]

In conventional key telephone devices, once the answering machine automatically answers an incoming external call, it is no longer possible to call the extension key telephone and make a call between the key telephone and the external line.

Therefore, if you forget to cancel the answering function setting on your answering machine, or if you set the answering function but there happens to be a recipient, you may not be able to answer the incoming call even though you can. There was a drawback.

The object of the present invention is to eliminate such drawbacks and to provide a key telephone device that can receive a PB double signal command sent from an outside line and send a pre-recorded voice message to the extension key telephone. It is about providing.

[Means to solve the problem]

The present invention consists of a main device connected to an outside line, one answering machine and a plurality of extension key telephones connected to the main device via an outside line call path and an extension call/data transmission/reception path. In the button telephone device comprising: comprising means for transmitting the message to the key telephone through a call/data transmission/reception path, each of the key telephones amplifying the message sent from the answering machine, and causing the answering machine to release the outside line when off-hook; Even after the answering machine automatically answers an incoming external call,
The key feature is that the key telephone can be called and a call can be made between the key telephone and an outside line.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

This button telephone device is composed of a main device 1 connected to an outside line 6, an answering machine 2 and N number of button telephones 3 housed in this main device. It is connected to the main device 1 through a call path 4 and an extension call/data transmission/reception path 5.

The answering machine 2 includes a PB receiver 2-1, a recording/reproducing circuit 2-3, a data transmitting/receiving circuit 2-4, and a control circuit 2-2.
, an outside line path acquisition relay 2-5, and an extension line path acquisition relay 2-6.

Each button telephone 3 includes a telephone call circuit 3-1, a data transmission/reception circuit 3-3, a control circuit 3-2, a speaker 3-6,
It includes a handset 3-7, an outside line path acquisition relay 3-4, and an extension line path acquisition relay 3-5.

In the button telephone device configured as described above, the relay 2-5 for acquiring an outside line path is activated while the answering machine 2 is responding to an incoming outside line call. At that time, when a command based on the PB double signal is sent from the outside line 6, the PB receiver 2-1 receives it, decodes it in the control circuit 2-2, and meters the extension path acquisition relay 2-6. Recording and playback circuit 2
-3 is activated, and a prerecorded voice message is sent to the extension call/data transmission/reception path 5. The content of the command by the PB double signal is transmitted to the data transmitting/receiving circuit 3-3 in the button telephones (1 to N) through the extension call/data transmitting/receiving path 5 by the data transmitting/receiving circuit 2-4.
can be conveyed to. In response to this, the control circuit 3-2 meters the extension path capture relay 35, activates the speaker drive circuit in the call circuit 3-1, and sends data from the answering machine 2 through the extension call/data transmission/reception path 5. The incoming voice message is amplified from the speakers 3-6 in the key telephones (1 to N).

When the recipient asks about this audible message, he or she can use the button telephone (
When one of the handsets 3-7 (1 to N) is off-hook, the relay 3-7 for capturing the outside line path of that key telephone
4, and then break the extension path capture relays 35 of the button telephones (1 to N), the outside line path capture relays 2-5 and 2-6 of the answering machine 2, and the outside line 6 A path is created between the key telephone and the off-hook key telephone, and a call can be made.

As described above, according to this embodiment, the main device 1.
The PB receiver 2-1 in the answering machine 2 receives a command based on the PB double signal sent through the external call bus 4, and based on the command, the message recorded in advance in the recording/playback circuit 2-3 is sent to the extension call/receiver 2-1. Communication circuit 3- of key telephones (1 to N) through data transmission/reception path 5
1 and can be amplified from the speaker 3-6. At that time, by off-hooking the handset 3-7 of one of the key telephones (1 to N),
The answering machine 2 releases the outside line 6, and the off-hook button telephone captures the outside line 6, making it possible to talk to the outside line.

〔Effect of the invention〕

As explained above, the button telephone device of the present invention responds to an incoming outside line by transmitting a voice message prerecorded in the answering machine from the speaker of the key telephone in response to a command using a PB double signal sent from the outside line. , even after the answering machine automatically answers, the key telephone can be called, and the call can be switched to between the key telephone and an outside line.
