Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used in combination with an answering machine, and particularly relates to a system for transmitting, receiving and recording a caller identification signal.

Generally, in an answering machine, a caller's business is recorded by voice on a magnetic tape.

However, in the past, for example, while the calling party was thinking about what to say during a call, the telephone line would be opened by the automatic line release function, or the called party would feel reluctant to talk because there was no other party on the call. There were cases in which the caller stopped the call, and the answering machine function was not fully performed.

Furthermore, when the owner of an answering machine wants to play back and listen to the recorded content, it takes the same amount of time as the actual recording time, so it is not possible to check the content in a short time.

On the other hand, if a signal that identifies the caller is recorded, it is often sufficient for the owner to call back later based on the record when the owner returns home, and the caller identification signal is recorded. The feature is very useful in answering machines.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a system that includes a device for receiving and recording calling party identification signals.

The gist of the present invention is to convert the calling party identification signal transmitted from the calling party side into a digital signal, store it, and further record this, and a calling party identification signal receiving and recording device for this purpose. The point is to provide the following.

To outline the configuration of one embodiment of the device of the present invention, it is constructed by adding the device described below to a conventionally known answering machine. According to this, when the called party is absent, the calling party's business is It becomes possible to record the calling party identification signal as well as to record the calling party identification signal.

In the present invention, after the answering message on the answering machine is finished, during the answering message, during the recording of the message, or immediately after, in short, while the direct current loop of the telephone line is closed, the calling party makes a call. A recording request signal for a calling party identification signal (hereinafter simply referred to as a recording request signal) and a calling party identification signal are transmitted to the called party.

There are no particular restrictions on the formats of the two signals, but regarding the former it is possible for the called party's terminal to determine whether or not it is a recording request signal, and regarding the latter it is possible for the called party's terminal to determine whether or not it is a recording request signal, and regarding the latter It is required that it be both identifiable and convertible so that it can be stored on the called party's terminal.

There is no particular restriction on the recording device either, and it can be appropriately selected within the scope of the spirit of the present invention.

In transmitting both of the above signals, a dedicated transmitter may be attached to the calling party's telephone, or a push-button telephone may be used.

This device for identifying a calling party can be implemented in various ways based on the principles set out below.

Here, the telephone on the calling party's side is a push-button telephone,
As an example, the above-mentioned calling party identification signal and recording request signal use a push button dial signal which is transmitted by operating a push button provided here.

In addition, if the calling party's telephone is not a push-button telephone,
There is no particular difference in terms of technical concept, as it is sufficient to provide the same function, that is, a dedicated oscillator for transmitting both of the above-mentioned signals, on the calling party's side.

In addition, when using a push button dial signal, there are 12 types of information to be transmitted, 0 to 9 + * t#, so as a calling party identification signal, for example, by operating O to 9, It is preferable to send the caller's telephone subscription number, and it is preferable to send the recording request signal by operating, for example, X.

According to the standard for pushbutton dial signals, this dial signal has two predetermined frequencies, one each of a predetermined low group frequency and a predetermined high group frequency, corresponding to each piece of information.
It is transmitted by mixing sine wave signals of two frequencies.

However, it is clear from the above description that the two signals do not necessarily have to be a combination of two sine wave signals, and can be selected as appropriate.

Hereinafter, the present invention will be described based on examples with reference to the drawings.

The device of this embodiment is constructed by adding the device shown in FIG. 2 to the conventionally known answering machine shown in FIG.

First, an outline of the conventionally known answering machine shown in FIG. 1 will be explained.

In Fig. 1, when a calling signal is received from the calling party via the switchboard to the called party's telephone via telephone lines L1 and L2, if the answering machine function is set by switching the switch SW. , the calling signal detection circuit 2 provided in the line circuit 1 detects this signal, operates a relay interlocked with the calling signal detection circuit 2, and connects its contact R2.
is activated, a pulse signal S1 is output to the control circuit 4, and the relay A is energized.

Along with this, contact a closes to close the DC loop of the telephone line, and contact a1 becomes make (closed) to drive the response mechanism 5, and the response message S2 recorded in advance on tape is sent to the telephone line. L1. It is sent to the calling party via L2.

This response message S2 is simultaneously applied to the audio monitoring circuit 6, and if the silence continues for a predetermined period of time or more, a first silence detection pulse signal S3 is issued to the control circuit 4.

Based on this, the control circuit 4 energizes the relay B, and its contact b1 becomes a break (open) and the response mechanism 5 stops, and the contact b2 becomes a make (close) and the message recording mechanism 7
is driven.

The business voice signal S5 transmitted from the calling party is recorded on a recording tape provided in the recording mechanism 7.

When the transmission from the calling party is completed, a second silence detection pulse signal S3 is sent from the voice monitoring circuit 6 to the control circuit 4.
' to restore relays A and B, the message recording mechanism 1 is stopped, and the answering machine function is restored to its original standby state.

Next, the apparatus of this embodiment will be described in more detail with reference to FIG. 2, and a method for transmitting a calling party identification signal and a recording request signal from the calling party side will now be described.

First, examples of both types of signals have already been described, but according to the present invention, the signal can be sent even when the above-mentioned answering machine is recording a message or when it is completed, or when a response message is being sent or when it is finished. It does not affect the purpose.

For example, if a response message is being sent, a voice message such as ``Please press the X mark on the push-button telephone and then press your subscriber telephone number'' will send an X mark, equivalent to a recording request signal, and the subscriber telephone number for recording. It is also possible to prompt the sending of a number, ie, a calling party identification signal.

Of course, various methods can be used, such as prompting the sending of both signals at the end of the response message, in other words, emitting a signal tone or the like from the called party's answering machine to notify that the caller identification signal is ready for input. .

Further, after the answering machine transmits such a voice message and completes the answering operation, the well-known message recording operation is completed, and when the already mentioned message recording mechanism 7 stops, the calling party identification signal is output. It is also possible to emit a signal sound to notify that input preparation is complete.

If such a method is adopted, the recording request signal may be omitted from both of the above-mentioned signals.

Here, during the recording operation of the answering machine shown in Figure 1, the calling party sends both signals in the order of a recording request signal and then a calling party identification signal. explain.

Further, as described above, the X mark provided on the push-button telephone is used as the recording request signal, and the push-button dialing signal obtained by pressing the subscriber telephone number again is used as the calling party identification signal.

Furthermore, it is assumed that the recording request signal marked with an "X" is sent by the calling party before the calling party identification signal, that is, the subscriber telephone number is sent, and in the following example device, the sent identification signal is received. will be explained as being used to erase the contents of a memory etc. before loading it.

When the embodiment shown in FIG. 2 receives such a signal, it first applies it to bandpass filters F1 to Fn.

The number n of filters F1 to Fn is equal to the sum of the types of low group and high group frequencies described above, and in this embodiment, since the calling party's telephone is a push-button telephone, n is 7.

Then, the signal from the calling party is applied to the integrating circuits 1-I via the filters F1-Fn and integrated, and then shaped by the waveform shaping circuits W1-Wo.

Therefore, in this embodiment, the two-frequency mixed signal sent from the calling party appears in any two of the seven waveform shaping circuits W1 to Wo.

This output is further converted into a 4-bit signal by a decoder 11.

In this way, the calling party identification signal sent from the calling party side is converted into digital, and the number of pits required for this is as follows:
It is necessary to determine it appropriately according to the method for determining the above-mentioned signals, and in this embodiment, 4 bits are required because 12 types of signals are encoded into binary code.

As described above, the calling party identification signal by two-frequency mixing is converted into digital data, and in this embodiment, this data is further stored in the memory device as follows.

According to this embodiment, the calling party identification signal is stored during recording of the message.

When the recording operation starts, a gate signal is sent from the flip-flop circuit 21 which is set by the first silence detection pulse signal S3 of the device 30 explained in FIG. 1 and reset by the second silence detection pulse signal S3'. Usable signal S for circuit 12
3"6in is applied.

A transmission signal 85' including the recording request signal and identification signal transmitted from the calling party during recording of the business is passed through the filter F1.
~Fn, integrating circuit 11 ~In, and waveform shaping circuit W1~
It is added to the decoder 11 via Wo.

The output 55-1 of the decoder 11 is applied to the comparison circuit 13 with the gate open since the enable state signal S3'' is applied to the gate of the gate circuit 12.

On the other hand, a 4-bit comparison signal equal to the recording request signal, that is, the stamp signal, is set in the comparison circuit 13 in advance, and the decoder output 55-1 is finally compared with this comparison signal. Ru.

When the calling party operates the X button during recording of the business to indicate his intention to start calling the subscriber telephone number, the comparison circuit 13 receives this and determines that it is a recording request signal, and outputs the signal S6. Output to shot multi-by-break 14.

The one-shot multi-bi flake 14 receives a pulse signal S
7 to activate the memory erase circuit and clear the memory contents of the memory device 17.

After the memory has been erased, a signal S8 is applied from the memory erase circuit 15 to the write circuit 16 to issue a write command.

In this way, when the recording request signal is received, the preparation for recording the calling party identification signal is instantaneously completed.

Subsequently, each digit of the calling party's subscriber telephone number is transmitted by the calling party's push button operation.

Each digit of the calling party subscription number is applied as a 4-bit signal to memory device 17 and stored at an address specified by write circuit 16, as described above.

The data detector 18 detects shifts in each digit of the calling party's subscriber telephone number.

In response to the output signal of the data detector 18, the write circuit 16
specifies the address of the next digit.

On the other hand, the write circuit 16 provides the information from the gate circuit 12 to the memory device 17 and specifies the address of each digit.

At this time, the output of the data detector 18 is received and an instruction is given to add 1 to the previous address.Furthermore, when the next shift is detected by the detector 18, the above operation is repeated, and the third digit is Below, information corresponding to all calling party subscriber telephone numbers is stored.

There are no particular restrictions on the configuration of the device that issues the writing stop command signal, but if the number of digits of the calling party identification signal to be written can be determined in advance, the digit counting circuit 25 can detect that all writing has been completed. Alternatively, the timer 19 may detect the elapsed time of shifting, and the stop phase +89 may be issued after a predetermined time has elapsed.

The timing between the signals in the above explanation is shown in FIG.

Next, reading from the memory device 17 will be explained.

Reading from the memory device 1-7 can be performed at any time after the writing is completed, but in this embodiment, the second silence detection pulse signal S3' is added to the readout circuit 22 as a readout command signal, and the memory Among the information stored in the device 17, the reading circuit 22 reads out the address where information consisting of 4 bits corresponding to the maximum digit of the calling party's subscriber telephone number is stored.
Read this by specifying.

In this way, the data are sequentially read from the memory device 17 and sequentially recorded by a recording device, for example, the printer 23, connected to the read circuit 22.

Of course, the printer 23 prints out a decimal number corresponding to the 4-bit input signal.

At the same time, the digit counting circuit 24 counts (
811 in FIG. 3) or the completion of reading (812 in FIG. 3) may be detected.

The digit counting circuit 24 is. When all the digits of a predetermined calling party subscription number are finished, a signal S12 is generated to reset the flip-flop circuit 21.

In the device of this embodiment, if the capacity of the memory device 17 is increased, the contents received during absence can be stored in the address of the mode without erasing the memory contents of the memory device 17, and the contents can be printed at once. As soon as it is output, it may be displayed on a display device (not shown).

In the device of this embodiment, the second silence detection pulse signal S 3'
is input to the multi-by-break 20 and the flip-flop circuit 21 is set.

The output 5IO1 may be used to drive a relay (not shown) to break (open) the contact R10 shown in FIG. 1, thereby cutting off new incoming calls after the writing is completed.

In addition, various recording devices 23 can be selected as appropriate, and the output thereof is not limited to simply outputting the subscription number.
If the user can write in the time and frequency of incoming calls, as well as address, name, company name, etc., in the memory device 17, it is easy to provide the system to simultaneously output information such as the time and frequency of incoming calls.

According to the present invention, a conventional answering machine can be made into a much more useful device, and various practical effects can be achieved.
