DETAILED DESCRIPTION OF THE INVENTION

[Object of the Invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an answering machine which can start a predetermined remote control operation based on a control signal sent from a calling side through a wired line in an answering machine function operation mode.

[0003]

2. Description of the Related Art A conventional answering machine of this type is configured to accept a control signal from a wired line only during transmission of a response message and activate a remote control operation corresponding to the control signal.

Here, the reason for limiting the reception of a control signal related to remote control only at the time of transmitting a response message is as follows.

[0005] That is, if the acceptance of the control signal is allowed during the recording of the business message after the transmission of the response message, the control signal is recorded in the business message.

In this case, when the user subsequently instructs the reproduction of the business message by operating the remote controller, the control signal is reproduced together with the business message, and the answering machine malfunctions due to the reproduced control signal. There is also.

For this reason, in a conventional answering machine,
It has been set so that a control signal from a wired line is accepted only while a response message is being sent.

Therefore, in the conventional answering machine, if the transmission period of the response message on the receiving side is short, the transmitting side may not be able to transmit the control signal relating to the remote control during the short period.

In this case, the receiving side immediately enters the message recording mode of the business message, and since the reception of the control signal is prohibited, remote control cannot be performed.

[0010] The same applies to a case where the control signal is output due to ambient noise or the like but the receiving side cannot detect it within the response message transmission period.

[0011]

As described above, in the above-mentioned conventional answering machine, a control signal relating to remote control is recorded together with the message, and when the operation proceeds to the reproduction operation, the control signal is recorded together with the message. In order to prevent the device from malfunctioning due to the reproduced control signal, the control signal is received only when the response message is transmitted.

Therefore, in this type of conventional answering machine, for example, the input of the control signal cannot be made within the transmission period of the response message or the influence of the ambient noise or the like despite the transmission of the control signal. If this cannot be detected on the receiving side, for example, the message message recording mode is immediately set and the acceptance of the control signal is prohibited, so that the transition to remote control is often not smooth.

The present invention eliminates this problem and increases the probability that the control signal is accepted by extending the period for accepting the control signal related to remote control, so that the answering machine can always perform stable remote control. The purpose is to provide.

[Configuration of the Invention]

[0015]

In order to achieve the above object, according to the first aspect of the present invention, a response message is sent to an originating side when an incoming call is received, and then a voice signal sent from the originating side is sent to the subject. In an answering machine having an answering machine function mode for recording as a message, when operating in the answering machine function mode, a detecting means for detecting a control signal received from the calling side, and receiving during the recording of the business message Recording prohibition means for prohibiting recording of control signals,
A storage means for storing control data corresponding to a specific operation in advance, and determines whether a control signal received during recording of the business message matches the control data, and stops the recording if they match, And a control means for starting control of a specific operation corresponding to the control data, and controlling to continue recording of the business message if they do not match.

[0016]

In the answering machine of the present invention, the reception period of the control signal relating to the remote control from the calling side is extended to after the response message is transmitted and during the recording of the business message.

A problem in accepting a control signal during recording of the business message is that the control signal is recorded together with the business message.

In view of this point, according to the present invention, when a control signal is received from the transmitting side after entering the message recording mode, the control signal is detected in a state where the recording section of the message is disconnected from the wire line. To do.

As a result, the control signal is not recorded together with the message, and the control signal is not reproduced and the malfunction does not occur.

Accordingly, the control signal can be input to the transmitting side even during the recording of the business message, and the control can be performed even if the response message transmission period of the receiving side is extremely short or there is disturbance such as ambient noise. A stable remote control operation can be realized by reliably detecting the signal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing one embodiment of an answering machine according to the present invention.

In FIG. 1, 1 is a wired line, 2 is a line relay circuit, 3 is a receiving amplifier, 4, 7, 11, 13, 2
0, 21 are switches, 5 is a microphone, 6, 14 is an amplifier,
8 is a solid-state recording circuit, 9 is a low-pass filter, 10 is a control circuit, 12 is a transmission amplifier, 15 is a receiver, 16 is a commercial power supply line, 17 is a power supply circuit, 18 is a DC stabilized power supply line, 19
Is a tape recorder section, 22 is a PB detection circuit, and 23 is an incoming call detection circuit.

In this answering machine, each circuit is operated by power supply from a power supply circuit 17 for obtaining a stabilized DC power supply from a commercial power supply.

Hereinafter, the operation will be described in detail with reference to the flowchart shown in FIG.

First, a call signal from the wired line 1 is detected by the incoming call detection circuit 23, and the detection output is input to the control circuit 10.

The control circuit 10 determines whether there is an incoming call based on the detection output of the incoming call detection circuit 23 (S2).
01).

Here, when it is determined that there is an incoming call,
Next, the control circuit 10 determines whether or not the device is set to the answering machine mode (S202).

If the answering machine mode is not set, a normal incoming call is made (S203).

On the other hand, when the answering machine mode is set, the control circuit 10 closes the line relay circuit 2 and forms a communication path for the wired line 1 (S204).

Next, the control circuit 10 activates the solid-state recording circuit 8 and sends the response message reproduced from the individual recording circuit 8 to the low-pass filter 9, the switch 11, the transmission amplifier 1
2. Transmission is made to the wired line 1 via the line relay circuit 2 (S205).

In the meantime, the control circuit 10 monitors whether or not all response messages have been transmitted (S206).

When the transmission of the response message is completed, the control circuit 10 then transmits the audio signal transmitted from the wired line 1 (transmission side) to the tape recorder through the reception amplifier 3 and the switch 4 in response to the response message. The message is recorded in the unit 19 as a business message (S207).

In the operation mode of recording the message, the control circuit 10 monitors whether there is an incoming PB signal (control signal for remote control) from the wired line 1 (S208).

The monitoring of the incoming of the PB signal is continued until the end of the recording of the message is detected in S209.

If the recording of the business message is completed without receiving the PB signal, the control circuit 10
Releases the communication path formed in S204 (S210), and ends the answering machine mode operation.

On the other hand, when a PB signal is sent from the wired line 1 during the recording of the message, the PB signal is input to the PB signal detection circuit 22 through the line relay circuit 2 and the receiving amplifier 3.

Here, the PB signal detection circuit 22 converts the PB signal input at this time into a signal of "1" or "0", and transfers this converted signal to the control circuit 10.

While the PB signal detection circuit 22 detects the output, the control circuit 10 keeps the switch 4 open (S211).
It is prohibited to be recorded on.

The control of the switch 4 is performed while the PB signal detection circuit 22 has a detection output, that is, in step S212,
The process is continued until the end of reception of the B signal is detected.

In S212, when the end of the reception of the PB signal is detected, the control circuit 10 sends the PB signal detection circuit 2 during that time.
2 (S213), and
A comparison is made as to whether or not this detection result matches a password registered in a self-memory set in advance (S21).
4).

Then, if they match, the recording of the business message previously performed is immediately stopped (S21).
5).

After that, the control circuit 10 executes various control operations corresponding to the personal identification number from the calling side, which has been recognized as coincident in S215 (S216).

As described above, according to the present invention, since the switch 4 is controlled to be opened while the PB signal is detected,
The B signal does not need to be recorded in the tape recorder unit 19.

In addition, when the message is reproduced, the PB signal is reproduced by the tape recorder section 19, passes through the switches 20, 11, the transmission amplifier 12, and the reception amplifier 3, and is detected by the PB signal detection circuit 22, thereby causing a malfunction. Can also be prevented.

As described above, in the present invention, the period in which the PB signal can be transmitted is extended to the recording period of the message, so that the transmitting side can perform remote control when the transmitting period of the response message from the receiving side is short. It is possible to deal with it with a margin, and it is possible to reliably shift to the remote control while inputting the password by the PB signal after entering the message recording.

In the above-described embodiment, an example in which the PB signal is received only during recording of the business message has been described. However, it is needless to say that the PB signal can be received even when the response message is transmitted, as in the related art.

As described above, according to the present invention, a response message is sent to a caller when an incoming call is received, and thereafter,
In an answering machine having an answering machine function mode for recording a voice signal sent from a calling side as a message message, a detecting means for detecting a control signal received from the calling side when operating in the answering machine mode. Recording inhibiting means for inhibiting recording of a control signal received during recording of the message, storage means for storing control data corresponding to a specific operation in advance, and a control signal received during recording of the message. It is determined whether or not the data matches the control data. If the data matches, the recording is stopped, control of a specific operation corresponding to the control data is started, and if not, the recording of the message is continued. And control means for recording the message when the control signal which is not registered and set in advance is detected during the message recording. Without stopping, it is possible to record continuously, thereby, only the person who knows the control data (personal identification number), it is possible to perform remote operation,
It is possible to prevent a person who does not know the control data from performing the above operation.
