Description

The present invention relates to an answering machine, and more particularly to an answering machine using an IC memory.

[Conventional technology]

Conventionally, an answering machine using this type of IC memory does not perform any special control for recording a remote control signal during recording of a response / message message in remote operation.
The remote control signal sound is recorded and played back together with the response / message message.

[Problems to be solved by the invention]

The above-mentioned conventional answering machine using the IC memory is designed to record the remote control signal sound in the recording process by remote control. Even if the push button of the side telephone is not pressed, another remote control operation is activated, which causes a malfunction of the answering machine.

[Means for solving problems]

An answering machine according to the present invention is an answering machine that uses an IC memory as a recording storage medium, a detecting means for detecting a remote control signal in a voice band sent from a telephone line, and an analog voice information from the telephone line. A conversion transmitting means for converting the digital voice information to digital voice information and outputting it to the IC memory, and converting the digital voice information from the IC memory into the analog voice information and outputting the analog voice information to the telephone line.
A control means for controlling recording / playback to / from the IC memory according to the detection output of the detection means, wherein the control means detects when the detection means detects the remote control signal during recording of voice from the telephone line. The address of the IC memory at that time is stored, the address stored after interrupting or ending the recording process is newly set as a recording stop position, and the digital audio information is read from the IC memory up to the address during reproduction.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

 FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, an answering machine 1 of the present embodiment is provided with a remote control signal detection unit 12 for detecting a remote control signal of a caller input via a telephone line 2 and a response / message for the caller. D / A converter for converting analog voice information into digital voice information and vice versa
An IC memory 14 for accumulating digital voice information, and a function control unit 13 for recording / reproducing the digital voice information and controlling the inside of the answering machine 1.

 Next, the operation of this embodiment will be described.

The answering machine 1 detects an incoming call from the telephone line 2 and sends a response message (not shown) to the calling party, and the calling party enters a password from a telephone (not shown) on the calling side. Once recognized, remote control operation becomes possible.

The number of the remote control operation is performed from the calling side telephone, for example, when the push button "1" is pressed, the message is recorded, and when "2" is pressed, the message is played.

Next, the caller presses "1" of the push button on the caller's telephone in order to inject the message, and the remote control signal for message recording is transmitted via the telephone line 2 to the answering machine 1
Is input to the remote control signal detection unit 12, and the detection signal is sent to the function control unit 13. The mechanism control unit 13 determines that the detection signal is a message recording so that the message recording can be started.

The Adalog voice information for the caller's message from the telephone line 2 is converted into digital voice information by the D / A converter 15 and stored in the IC memory 14 for voice data.

When the caller presses the push button "2" on the caller's telephone during this message recording, the remote control signal for message playback is input via the telephone line 2 and detected by the remote control signal detector 12. The remote control signal detection unit 12 transmits the detection signal to the function control unit 13. The function control unit 13 is the IC memory 14 at that time.
The IC memory address is stored and the recording process is interrupted, and the stored IC memory address is newly set as the recording stop position of the previous recording.

Next, the function control unit 13 determines that the remote control signal “2” is the message reproduction, and starts the message reproduction, but the digital voice information from the IC memory 14 reaches the recording stop position of the stored IC memory address. The message is read and the message is reproduced, and the remote control signal sound generated by the push button is not reproduced.

In the message reproduction sound, the digital voice information from the IC memory 14 is converted into analog voice information by the control of the function controller 13.
It is converted by the A converter 15 and output via the telephone line 2.

〔The invention's effect〕

As described above, according to the present invention, when recording a remote control response and a message, the control unit stores the address of the IC memory when the remote control signal detecting unit detects the remote control signal, and the recording process is performed. After the interruption, the address of the IC memory stored after the interruption is set as the recording stop position, and by deleting the remote control signal sound recorded in the IC memory at the time of playback, the remote control signal sound is not played back and it is possible to prevent malfunction of remote operation. The effect is that you can do it.
