Abstract

PURPOSE:To facilitate a loopback telephone operation by storing a telephone number sent with a DTMF signal from a transmitting person, reading the number, and executing an automatic dial transmission. CONSTITUTION:When a receiving input is executed to an input terminal 1, it is detected by a reception detecting circuit 18, a control part 19 calculates a calling frequency, and when the frequency reaches a prescribed frequency, a line is closed by a line closing circuit 2. Next, when a loopback telephone is required, from a response memory 5 through a reading circuit 6, a response message to contain even the request of a telephone number input with the DTMF signal by a push button is sent. A business message from a transmitting person side after a response message completion is recorded in a business memory 8, simultaneously, the telephone number by the DTMF signal is converted to 4-bits data by means of a tone detector 11, and the data are recorded in a data memory 13. By reading the record, the dial automatic transmission is executed, and the loopback telephone operation after a business message reproduction can be easily and simply executed.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an answering machine.

(Summary of the Invention) The present invention is capable of transmitting a prerecorded response message to the caller after receiving a telephone call, recording the message sent by the caller after the message has been sent, and replaying the recorded contents at will. A response message is sent to the configured answering machine to inform the caller that the telephone number should be sent in the DTME signal, and the telephone number sent by the caller in the DTMF signal is recorded.

When the recipient performs an automatic dialing operation as necessary, the recorded telephone number is read out and the dialed call is automatically made. (Prior Technology) Conventionally, this type of answering machine When a telephone device receives a call, it sends a pre-recorded response message to the caller, records the message sent by the caller after the message is sent, and then retrieves the recorded message when the receiver comes home. It can be played at will.

(Problem to be Solved by the Invention) Conventionally, when the recipient needs to call the other party back after reproducing the message, the phone number is called based on the recorded message Q99 name. This was a time-consuming and troublesome process, as it required both the user to research and dial the phone number recorded in the message, and to write down the phone number recorded in the message on memo paper and then dial the phone number.

(Means for Solving the Problems) In order to solve the above problems, the present invention sends a pre-recorded response message to the caller after receiving a call, and after sending the call, sends the message sent by the caller. In an answering machine configured to record a telephone number sent by a caller using a DTMF signal, the answering machine includes a number recording means for recording a telephone number sent by a caller using a DTMF signal, and a telephone number is read out from the number recording means and automatically dialed when an automatic dialing operation is performed. The system is equipped with an automatic transmission means for making a call.

(Function) With the above configuration, if the recipient needs to call back after reproducing the message, if the recipient performs the automatic dialing operation, the recorded telephone number will be read and the dialed number will be automatically dialed. Therefore, it saves time and effort when calling back and is extremely convenient.

(Example) Examples of the present invention shown in the drawings will be described in detail below.

1 is a telephone line input terminal, 2 is a line closing circuit that closes the telephone line when receiving or making an outgoing call, 3 is a dialing circuit that creates a pulse or tone transmission signal, and 4 is for sending and receiving voice calls. Speech network that performs 2-wire to 4-wire conversion, 5
6 is a response memory for recording a response message; 6 is a speech network for reading out the response message recorded in the response memory 5; Dial transmission circuit 31, line connection circuit 2, and a continuous output circuit that sends out data via input terminal 1, 7 is input terminal 1. Line closing circuit 2. A writing circuit 9 records the caller's message sent through the dial transmission circuit 3 and the speech network 4 in a predetermined recording area of the message memory 8; 11 is a readout circuit that reads out the business information and outputs it as a sound from the speaker 10; 11 is a DTMF signal t-
A tone decoder 12 converts the data into 4-bit data, and a write circuit records the data from the tone decoder 11 in a predetermined area of the data memory 13. The write circuit 12 and the data memory 13 constitute a number recording means for recording the telephone number sent by the caller as a DTMF signal. 14 is data memory 13
15 is a readout circuit that reads out the number recorded in a predetermined area and outputs it to the dial transmission circuit 3; 15 is a message playback button;
16 is a dial button, 17 is a display section for displaying the recording state of the telephone number, 18 is an incoming call detection circuit, and 19 is a control section for controlling the input/output of each of the above sections.

The above dial transmission circuit 3. Readout circuit 14. The dialing button 16, the control unit 19, etc. constitute automatic dialing means that reads a telephone number from the number recording means and automatically dials the telephone number in response to an automatic dialing operation.

In addition to the above configuration, when an incoming call is input to the input terminal 1, the incoming call detection circuit 18 detects the incoming call, the control unit 19 counts the number of calls, and when the number of calls reaches a predetermined number, the line closing circuit 2 Close the line. Next, the readout circuit 6 is instructed to read out a prerecorded response message from the response memory 5 and the speech network 4. The dial transmission circuit 3 sends the signal to the caller via the line connection circuit 2 and the input terminal 1. At this time, for example, if a call back is required, a message requesting the user to input a telephone number using a DTMF signal from the button is recorded in the response memory 5 in advance.

Next, after sending the response message, the message sent by the caller is sent to the input terminal 11 line closing circuit 2° dial sending circuit 3. Write circuit 7 via speech network 4
is recorded in a predetermined area of the data memory 8 by the tone decoder 11 when the call number is input by the DTMF signal of the telephone, and is recorded in a predetermined area of the data memory 13 by the write circuit 12. to be recorded. The message and the telephone number data are recorded in association with each other as shown in Figure 2. For example, if the message is recorded in the first area of the message memory 8, the telephone number data is also recorded in the data memory. It is recorded in the first area of No. 13.

When the recipient returns home from outside and presses the playback button l5, the control unit 19 instructs the readout circuit 6 to read out the message recorded in the first area of the message memory 8, and outputs the message from the speaker 10. At the same time, the readout 1 circuit 14 is instructed to read out the telephone number data recorded in the first area of the data memory 13, and if data is recorded, the display section 17 displays the line for that line. indicate.

When the dialing button 16i is pressed in accordance with this display, the control unit 19 closes the line using the line closing circuit 2, reads out the dialing circuit 3, and controls the reading circuit 147 according to the read telephone number data to automatically dial. I will do it.

Note that the response memory 5, the business memory 8, etc. may be of either a tape recording type or an IC recording type.

(Effects of the Invention) As described above, according to the present invention, if the caller inputs a telephone number using a DTMF signal, the receiver will automatically dial the number and make the call by simply performing the automatic dialing operation. It is possible to save the time and effort required in the conventional method.
