DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an answering machine ID that allows the user to listen to the telephone number of a caller when he or she is away from home.

2. Description of the Related Art Conventionally, there has been known an answering machine which is a combination of a tape recorder and a telephone set, which records a caller's message when the caller is away from home. In this case, the caller has to speak into a tape recorder, and if he or she is unable to do so, the caller may feel confused.

The present invention was made to improve these drawbacks.
A detailed explanation will be given below according to examples.

FIG. 1 shows an embodiment of the present invention, which is a push-button telephone. In the figure, the control circuit 3 includes RAMs 31, 32, .
33 and a command circuit 34, and the switch circuit 5 has switches 51, 52, 53 and 54. Button information from the keyboard 1 is added to the RAM 31 and connected to the contacts of the switch 54. The output signal of RAM 31 is connected to contact B of switch 54. The input terminal of the frequency converter 70 is connected to the movable contact of the switch 54, and the output terminal is connected to the normally open contact 8 of the hook switch 16 via the amplifier 12 and resistor 11. The output terminals of RAMs 32 and 33 are connected to the input terminal of the speech synthesizer 20. Contact A of the switch 52 is connected to the micro 2 of the handset 6, contact B is connected to the output terminal of the voice synthesizer 2, and the movable contact is connected to the normally open contact B of the hook switch 16 via the amplifier 9 and resistor 10. Connected. A station line signal from the station line circuit 17 is applied to the movable contact of the hook switch 16,
The normally closed contact A is connected to the bell 15 via the amplifier 14 and to the contact B of the switch 53, and the normally open contact B is connected to the movable contact of the switch 51 via the amplifier 8. Contact A of the switch 51 is applied to the speaker 61 of the handset 6, and contact B is applied to the keyboard signal generator bundle. The contact A of the switch 53 is open, and the movable contact is connected to the first control terminal of the automatic call receiving circuit 18. The output of the keyboard signal generator 4 is applied to the RAM 32, the output 35 is applied to the read control terminal of the RAM 31, and the second control terminal of the automatic call receiving circuit 1B, and the outputs 36 and 37 are used for writing and reading the RAM 32, respectively. The output 38 is applied to the write control terminal of RAM 31. The automatic call receiving circuit 18 controls the hook switch 16 and also controls reading of the R and AM 33. The operation of the above configuration will be explained below with reference to FIG.

When the switch 16 is taken off-hook, the switch 16 is connected to the normally open contact B side. Next, when the other party's number is entered using the button on the keyboard 1, the button information is applied to the frequency converter 7 via the switch 54, as is well known, and is sequentially frequency converted into a dial tone signal, which is output to the central office line. to call the other party's telephone, and the handset 6 becomes available for conversation.

When the handset 6 is placed, the switch 16 is on-hook and connected to the normally closed contact A side. At this time, when receiving a call from the other party, the amplifier 14 rings the call bell 15, so that when the receiver is picked up, the call goes off-hook) and the user can talk. At this time, the amplifier 14 and the automatic call reception circuit 18 are disconnected by the switch 53.

Next, the case where the user is absent will be explained with reference to FIG. Note that a - k in Fig. 2 is a - k in Fig. 1.
Indicates the timing at which the blocks marked with are operated.

Enter the previous phone number into RAM 31 like el.

After this, when the central office line signal from the caller arrives like al, the switch 16 is in the on-hook state, so the amplifier 1
The ringing signal amplified by 4 causes the bell 15 to ring like C. This calling signal is also applied to the automatic call reception circuit 18 via the switch 53, where it is detected and generates the call reception signal d1. When the incoming call signal d1 rises, the switch 16 goes off-hook, the calling signal stops, the bell sound C also stops, and the call becomes possible.

Furthermore, the incoming call signal d1 controls R and AM33) to read out a message signal "Please enter your telephone number" stored in advance. This message signal is transmitted to the caller via the amplifier 9 as a voice signal S1 by the voice synthesis circuit 2. The caller then enters his phone number a3 and, if necessary, R, R, and R respectively before and after it.
Enter a write start command a2 and a write end command a4 to AM32 using the button on your telephone.

This information is transmitted to the keyboard signal generator 4 via the office line circuit 17 and amplifier 8, and the dial signals are converted into keyboard signals one after another. A write start command a2 to the RAM 32 from this keyboard signal is sent to the command circuit 34.
is detected, a write command signal 36 is generated, and the caller's telephone number is written into the RAM 32 (as in 11).

Also, the post-write command circuit 34 detects the write end command a4 from the keyboard signal, and outputs the read command signal 35.
occurs. This read command signal 35 first controls the automatic call receiving circuit 18, and the hook signal 35 as d2 causes the telephone number of the destination written in the RAM 31 after the above-mentioned off-hook to be read as e2. This read keyboard signal is applied to the frequency converter 7 via the switch 54, where it is converted into a dial signal to call the destination.

When I'm on the go, I pick up the handset and type a read command into the button like the A5. Then, as described above, the read command is converted into a keyboard signal by the keyboard signal generator 4, which is detected by the command circuit 34 and a read signal 37 is generated.

This readout signal 37 causes the calling party's telephone number to be read out from the RAM 32 as j2, which is converted into a voice signal 'j2 by the voice synthesizer 2, and is notified to the destination.

Even if you happen to be absent and unable to contact someone when you are called, you can call the main answering machine from any location and enter the read command as shown in a5 to make the call in the same way as above. You can do this by knowing the caller's phone number.

Next time, if you want to change your phone number while you are away, first call your home and use the RA button, such as the # symbol or the American symbol.
Enter a writing command to M31, and then enter a new telephone number using the button on the key telephone at your destination. Then, in the same manner as described above, the keyboard signal generator 4 first converts the write command into a keyboard signal, and the command circuit 34 sends the write command signal 3B to the RAM 31. As a result, R, AM31 reads the subsequent new telephone number.

Note that a display device may be added to the above-mentioned answering machine so that the telephone number input by the caller as described above is immediately displayed on this display device. In this way, for example, even if you are not at home, you can leave the caller on answering machine and know in advance who the caller is based on the entered phone number, so you can call again only if it is necessary. You can.

For example, the control circuit 3 and the like in the above embodiments can be constructed using a microcomputer or the like.

As described above, according to the present invention, it is possible to know the telephone number of the caller of a call to the answering machine while on the go, and in this case, the caller can simply enter his or her own telephone number using a keyboard, etc. You can often get excellent benefits such as not having to make a phone call again to your place of work.
