BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an answering machine, and more particularly to an answering machine having a secret talk function.

[0002]

2. Description of the Related Art Recently, answering machines are provided with a confidential talk function, and a message is often transmitted from one specific person to another specific person.

[0003] This secret talk function is for monitoring a message recorded in an answering machine by inputting an ID code to a handset or a speaker to obtain a secret talk message.

[0004] Although this method is relatively simple, there is a problem that a secret message is eavesdropped since recording and reproduction are performed by analog signals.

For this reason, there is a telephone answering machine equipped with branch telephone off-hook detection to stop recording and playback if wiretapping is performed to prevent leakage of a secret message. There was a problem in that the status was not notified and the parties had to make adjustments, re-recording, etc. later.

In addition, analog secret devices for inverting the spectrum of analog signals and the like have been developed.

Accordingly, the present invention provides an answering machine which confirms a caller registered in advance and records / reproduces the message of the caller by using a caller number or the like via a secret device. provide.

SUMMARY OF THE INVENTION According to the present invention, there is provided a receiving means for receiving a caller number when receiving a call, a registering means for registering a predetermined caller number, and a call receiving means for receiving the caller number. Comparing means for comparing a calling party number and a calling party number registered by the registering means, and recording means for scrambling and recording a voice message from the calling party when the comparison by the comparing means matches. When a play button is operated and a specific caller number registered in the registration means is input, a scrambled voice message corresponding to the input specific caller number is generated. Reproduction means for reproducing after descrambling.

[0009]

When the incoming call signal from the caller matches the pre-registered caller number, the message is scrambled, recorded, descrambled and played.

When the input key determination unit 51 determines that the signal is the mode button 2 signal, a cs3 signal is generated and sent to the memory selection unit 52. The memory select unit 52 selects the second memory mode unit 57 based on the cs3 signal.

Next, when the answering button of the mode input section 50a is pressed, the pressing signal is transmitted to the input key discriminating section 5a.
1. The data is sent to the second memory mode unit 57 via the memory selection unit 52, and the absence mode is stored in the second memory mode unit 57.

After these operations are completed, the absence mode stored in the second memory mode section 57 is registered by pressing the registration button.

The registration of other modes and the like may be performed by the same operation.

When registering such a specific number, mode, etc., normally, the setting control unit 1
7. An OGM start signal and an OGM stop signal are called via the write / read sections 51 and 58, and these are stored and registered together with a specific number, a mode, and the like.

When a secret recording message is sent from a specific caller together with a caller number to the answering machine 10 in an empty channel state in which such registration has been performed (S1).
The caller ID and secret message are sent to
1. The incoming call signal is sent to the transmission / reception unit 12 and the incoming call signal is sent to the control unit 60 that is clock-controlled via the buffer memory 27.

When the control unit 60 receives the incoming call signal, it sends the incoming call signal to the setting control unit 17 and to the comparing unit 56. When the setting control unit 17 receives the incoming call signal, the writing / reading unit 55 of the first registration unit 14 is controlled, and the number of the specific person registered in the first memory number unit 53 is called. If there is a specific person's number, the number signal is sent to the comparing unit 56, and if there is no specific person's number, a no registration signal is sent to the comparing unit 56.

The comparing unit 56 compares the incoming call signal with the registration signal, and when the incoming signal matches the registration signal (S2),
The comparison output signal is sent from the comparison unit 56 to the setting control unit 17.

When the setting control unit 17 receives the comparison output signal, the recording / playback memory unit 44 and the FM
Control signals for controlling the signal generator 43, the scrambler 31, the disc rambler 49, and the switching units 32, 42, and 34a are sent.

When the recording / playback memory unit 44 receives the control signal, an OGM signal is generated (S3), and the transmission / reception unit 1
2. The abandoned state of the line is determined via the transmission / reception unit 11 (S4), and if it is not abandoned, the confidential recording state is maintained, and if it is abandoned, the confidential recording state is stopped.

If the confidential recording message has been commanded, the confidential recording state is maintained (S5). When such a state is determined, the OGM signal is stopped (S6).

When the FM signal generator 43, the scrambler 31, and the descrambler 49 receive the control signal, the scrambler 31 and the descrambler 49 are activated.

When the switching units 32, 42 and 34a receive the control signal, the contacts ac of the switching unit 32 are connected, and the switching unit 4
The two contacts a-c are connected to form a transmission / reception circuit, the contacts of the switching unit 34a are closed, and a tone ring signal is generated.

Therefore, the secret recording message is transmitted to the transmitting / receiving unit 1.
1. The transmission / reception unit 12 is sent to the recording / playback memory unit 44 via the scrambler 31 of the transmission / reception unit 12, and the secret recording message is scrambled and recorded (S7), (S7).
8).

If the line is not abandoned during the confidential recording, the confidential recording is continued, and if the abandonment is performed, the confidential recording is stopped (S9).

When the secret story recording message ends (S1)
0), the recording of the answering machine 10 is stopped (S1).
1) Secret recording is stopped (S12), and the initial state is restored. If the incoming signal and the registration signal do not match in the comparison by the comparing unit 56 (S2), a mismatch signal is sent from the comparing unit 56 to the setting control unit 17.

When the setting control unit 17 receives the mismatch signal,
The absence mode of the first memory mode 57 is set, and a control signal for controlling the recording / playback memory unit 44 and the switching units 32, 42, and 34a is sent from the setting control unit 17. Therefore, although the transmission circuit is formed, the scrambler 31 and the descrambler 49 remain in an inactive state, and a recorded message that is not scrambled is registered in the answering machine / reproduction memory 44.

In order to play back the confidential recorded message, the setting control section 17 is controlled by pressing the play button and operating the ten key section 50b, and the recording / playback memory section 4 is operated.
4. The reproduction signal is sent to the scrambler 31, the disc rambler 49, and the switching units 32, 42, 34a.

Therefore, the secret story recording message recorded in the recording / playback memory section 44 is descrambled by the descrambler 49, and is transmitted to the microphone section 39 via the analog-digital converter 33, the filter section 35, and the amplifier 38 as normal information. Will be played.

In order to play back a normally recorded message, the setting control section 17 is controlled by pressing a play button, and the message normally recorded in the recording / playback memory section 44 is converted to an analog / digital converter 33, a filter, and the like. The information is reproduced as normal information by the microphone unit 39 via the unit 35 and the amplifier 38.

Therefore, the confidential recording message can be reliably transmitted to the specific person, and the normal recording message can be recorded and reproduced as usual.

[0050]

According to the present invention, the answering machine records the confidential message in the message only when the person recording the confidential information registers the specific number and the like, and when a call signal corresponding to the registered number is transmitted. Since the confidential recorded message is reproduced by the specific number, the confidential recorded message does not leak to anyone other than the specific person.
