Description

[Detailed Description of the Invention] The present invention relates to a telephone device that integrates a cordless telephone and an answering machine. The present invention relates to a telephone device configured to allow two-way communication.

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

1 is a master station of the cordless telephone, which is composed of a transmitter 2 and a receiver 3, each connected to telephone lines L ₁ and L ₂ via a hybrid transformer circuit 4;
Audio signals from the telephone lines L ₁ and L ₂ are transmitted from the transmitter 2 to the slave station via the antenna 5, and the voice signals from the slave station are received by the receiver 3 and transmitted to the telephone lines L ₁ and L ₂ .
is configured to be transmitted to Reference numeral 6 denotes an incoming call detection circuit which detects an incoming bell signal, generates a tone signal _f1 for calling a slave station, and inputs it to the transmitter. Reference numeral 7 denotes an answering machine connected to telephone lines L ₁ and L ₂ , which plays messages recorded on tapes (not shown) or records messages from telephone lines L ₁ and L ₂ on magnetic tape. - Consists of playback equipment. Reference numeral 8 denotes a speaker connected to the telephone answering machine 7 via a switch 12, which amplifies the message recorded on the magnetic tape when the telephone answering machine 7 is operated in the playback mode. A microphone 9 is normally connected to the telephone answering machine 7 via a changeover switch 13, and is used to record a message sent when a call is received on a magnetic tape. And the other fixed contact 1 of the changeover switch 12
2C is connected to the other fixed contact 11C of the changeover switch 11 provided between the receiver 3 and the hybrid transformer circuit 4 of the cordless telephone 1, and the other fixed contact 13c of the changeover switch 13 is connected between the transmitter 2 and the hybrid transformer circuit 4. It is connected to the other fixed contact 10C of the changeover switch 10 provided between the circuits 4. In addition, the changeover switches 10, 11, 1
2, 13 movable contacts 10a, 11a, 12a, 1
3a is usually one fixed contact 10b, 11b, 1
Switched to 2b, 13b side, mutual call button 14
In conjunction with the operation of the other fixed contacts 10c, 11
c, 12c, and 13c side.

FIG. 2 is a diagram showing the configuration of the slave station 15, which includes a receiver 16 that receives the signal from the master station 1, a speaker 17 that amplifies the received audio signal, and a microphone that transmits the voice from the slave station 15. 18 and transmitter 19
It is made up of.

Next, the operation of the present invention having such a configuration will be explained.

First, when you go out and are away, in order to answer calls that come in while you are away, set the answering machine 7 to recording mode and use the microphone 9 to record a message to the effect that you are away on magnetic tape. , set to response waiting mode. When a call is received from an outside line, the telephone answering machine 7 is activated upon detection of a bell signal, and the first recorded message is sent to telephone lines L ₁ and L ₂ . Upon completion of sending the message, the telephone answering machine 7 is set to a recording state and the requirements of the caller are recorded. The above-mentioned operations are repeated each time a call arrives, and the requirements are sequentially recorded. When you return from going out and listen to the recorded content while you are away, you can rewind the tape on the answering machine 7 once and then switch it to playback mode, so that the recorded requirements can be played back and heard from the speaker 8. can.

Next, the operation of the cordless telephone will be explained.
First, when an incoming call is received from an outside line, the incoming call detection circuit 6 detects the incoming call by detecting a bell signal, and a tone signal f ₁ is generated and supplied to the transmitter 2, so that the tone signal f ₁ is transmitted to the slave station 15. will be sent to. Therefore, the slave station 15 that received the tone signal f ₁ generates the tone signal f ₁ through the speaker 17, and the slave station 1
Notify person 5 of the incoming call. When the person at the slave station 15 who notices the incoming call responds by operating an operation button (not shown), the slave station 15 transmits a response signal, and the master station 1 that receives this signal connects the line and It becomes possible to talk between station 15 and an outside line.

On the other hand, when making a call from the slave station 15, when the calling operation is performed, the master station 1 that has received the outgoing signal from the slave station 15 connects the line.
You can make an outside call from.

Next, mutual communication between a parent and a child using a cordless telephone will be explained.

First, when making a mutual call, operate the mutual call button 14 of the master station 1, and switch the changeover switches 10, 11,
12, 13 as fixed contacts 10c, 11c, 12c,
By switching to the 13c side, the transmitter 2 and receiver 3 of the master station 1 are separated from the hybrid transformer circuit 4, and the microphone 9 is connected to the transmitter 2 to the receiver 3.
Connect speaker 8 to.

Therefore, when a person at the master station 1 speaks into the microphone 9, an audio signal is transmitted by the transmitter 2 to the slave station 15, reproduced by the speaker 17 of the slave station 15, and the voice signal is A human voice signal is transmitted from a microphone 18 to a master station 1 via a transmitter 19, received by a receiver 3, and then reproduced by a speaker 8. In this way, the parent and child can communicate with each other. If a call arrives during a call between parent and child, the call detection circuit 6 detects the call and generates a tone signal _f1 , which is superimposed on the call signal, making it possible to know that the call has arrived even during the call.

As described above, the telephone device of the present invention incorporates a cordless telephone and an answering machine, and is structured so that the speaker and microphone for the answering machine are switched and connected to the cordless telephone, thereby allowing communication between the parent and child of the cordless telephone. It enables telephone calls and can be constructed at low cost by serving as both a speaker and a microphone.
