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 confidential communication function.

[0002]

2. Description of the Related Art Recently, answering machines have been provided with a confidential communication function so that a message is often transmitted only from one specific person to another specific person. ..

[0003] This confidential communication function normally allows a handset unit or a speaker to monitor a message recorded in an answering machine by inputting an ID code to obtain the confidential communication message.

Although this method is relatively simple, there is a problem that a confidential message is eavesdropped because recording and reproduction are performed by analog signals.

Therefore, there is an answering machine which is equipped with a branch telephone off-hook detection to stop recording and reproduction when wiretapping is performed to prevent leakage of confidential messages. However, there was a problem that the parties had to make adjustments or re-recording afterwards without being notified.

In addition, analog secret devices such as spectrum inversion of analog signals have been developed.

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

The first memory mode unit 54 via the memory select unit 52
The answering machine mode is stored in the first memory mode unit 54.

When the register button is pressed after these operations are completed, the number of the specific person stored in the first memory number section 53 and the answering machine mode are registered in the first memory mode section 54 in association with the number. It

The registration of the specific numbers and modes of other specific persons may be performed by the same operation. Next, the second registration unit 1
A case where the absence mode is registered in 5 will be described.
In this case as well, the same process as in the case of registration in the first registration unit 14 may be performed. That is, when the mode button 2 of the mode input unit 50a is pressed, the pressing signal is input to the input key determination unit 5
Sent to 1. When the input key determination unit 51 determines that it is the mode button 2 signal, the cs3 signal is generated and sent to the memory selection unit 52. The memory select section 52 selects the second memory mode section 57 based on the cs3 signal.

Next, when the absence button of the mode input section 50a is pressed, the pressing signal indicates the input key determination section 51,
The second memory mode unit 57 is connected via the memory select 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 register button.

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

When registering such a specific number, mode, etc., usually, the recording / playback memory section 44 is set to the setting control section 1
7. The OGM start signal and the OGM stop signal are called via the write / read units 51 and 58, and these are stored and registered together with the specific number, the mode and the like.

When a secret call recording message is sent from a specific caller to the answering machine 10 in the idle channel state in which such registration is performed (S1), the caller is called. The number and confidential message recording message are sent to the transmission / reception unit 11 and the transmission / reception unit 12, and an incoming call signal is sent to the control unit 60 which 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 the comparison 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, that number signal is sent to the comparing section 56, and if there is no specific person's number, a non-registration signal is sent to the comparing section 56.

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

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

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

If the confidential recording message is commanded, the confidential recording state is continuously maintained (S5). When such a state is judged, the OGM signal is stopped (S
6).

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 ac 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 story recording message is transmitted / received by the transmitting / receiving unit 1.
1, the transmission / reception unit 12, and the scrambler 31 of the transmission / reception unit 12 is sent to the recording / playback memory unit 44, and the confidential recording message is scrambled and recorded (S7), (S
8).

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

When the confidential recording message is completed (S1
0), the recording of the answering machine 10 is stopped (S1
1) The 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 comparison unit 56 (S2), the comparison unit 56 sends a non-matching signal to the setting control unit 17.

When the setting control section 17 receives the disagreement signal,
The absence mode of the first memory mode 57 is set, and at the same time, the setting control unit 17 sends a control signal for controlling the recording / playback memory unit 44 and the switching units 32, 42, 34a. As a result, although the transmission circuit is formed, the scrambler 31 and the descrambler 49 remain inactive, and the unanswered recording message is registered in the answering machine / playback memory 44.

In order to reproduce the confidential message recording message, the reproduction button is pressed and the numeric keypad 50b is operated to control the specific caller registration setting control unit 17, which controls the recording / reproducing memory unit 44, the scrambler 31, and the disc. The reproduction signal is sent to the rambler 49 and the switching units 32, 42 and 34a.

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

To play a normal recording message,
The setting control unit 17 is controlled by pressing the play button, and the message normally recorded in the recording / playback memory unit 44 is converted into the analog-digital converter 33, the filter unit 35,
The information is reproduced as normal information in the microphone 39 through the amplifier 38.

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