DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone set for automatically connecting a communication line after an incoming signal is detected, and more particularly, to setting of an operation state of a receiving side based on information transmitted from a destination. The present invention relates to a telephone capable of preventing leakage of a call voice transmitted from a calling side and performing an incoming call notification according to the convenience of a called side.

[0002]

2. Description of the Related Art Conventionally, for example, an answering machine has been proposed as a telephone for automatically connecting a communication line after receiving an incoming signal, and is generally used widely.

When an incoming call is received after the answering machine is set to the answering machine mode by the operation button, the answering machine detects an incoming signal and automatically connects a communication line with the calling side, and then the answering machine is set in advance. The message information generating unit generates response message information for the absence of the caller, and sends the generated message information to the caller through the automatically connected communication line, and then the voice information sent from the caller. Is recorded on the recording unit of the called party.

FIG. 4 is a time chart of a conventional telephone line automatic connection.

In FIG. 4, when an incoming signal (a) sent from the transmitting side is input, the incoming signal (a) is converted into a rectified incoming signal (b). Then, the incoming call is detected by the incoming call detection circuit and an incoming call detection signal (c) is generated.

If the telephone set is set to two ringing tones, it is detected at the second falling timing of the rectified incoming signal (b), and the active signal is detected.
That is, the signal becomes high level "1", and the line is automatically captured by the incoming call detection signal (c). Then, a predetermined outgoing message (OGM) is played,
This OGM signal (d) is transmitted to the transmitting side.

On the other hand, based on the rectified incoming signal (b), a bell ringing signal (e) set to a predetermined volume level
Is generated and output as a ringing tone from the speaker at a volume corresponding to the volume level of the bell ringing signal (e).

[0008] Thereafter, the message transmitted from the transmitting side is recorded in the recording / reproducing section. Then, when the person on the receiving side returns to the side of the telephone and operates a predetermined operation button such as reproduction, for example, the recording / reproducing unit outputs a message such as a call voice recorded during absence.

[0009] By setting the automatic line connection in this way, the person on the receiving side can confirm who called what kind of call during the absence.

[0010] Recently, in response to demands such as prevention of mischief and a desire to accept only a call from a specific person, a caller's call voice is recorded and the caller's call voice is output from a speaker. Answering machines with a monitor function called screening have also been proposed.

In a telephone having such a monitor function, when the owner of the telephone is away, a third party may hear a call voice from a caller. If that is not the case, the secret will be leaked.

Therefore, there is a problem that it is not always preferable to operate the monitor function during so-called answering machine recording.

In recent years, it is not always the case that the telephone is set to the answering machine mode only when actually answering, and the telephone owner does not want to answer the telephone for a good night's sleep, for example, at night. Even when there is no answering mode, the answering machine mode may be set. That is, there is a case where he is away.

However, even in the answering machine mode, when an incoming call is received, a ringing tone such as a bell rings until the automatic line connection is established, so that there is an advantage that it is not necessary to talk with the caller. There is a problem that the sleep sound is eventually disturbed by the ringing sound.

In a mobile phone and a second-generation digital telephone, which have become widespread recently, the telephone can be moved to various places. There is a problem that a ringing tone may be heard in a place, for example, a quiet place such as during a meeting.

[0016]

As described above, in a conventional telephone capable of automatic line connection, it is not necessary for the called party to directly answer by setting the automatic line connection. There is a problem that the notification of the incoming call such as the sounding of the sound may give a disadvantage such as disturbance of sleep due to the notification of the incoming call.

Therefore, the present invention eliminates such a problem,
It is an object of the present invention to provide a telephone capable of controlling all incoming call notifications based on control information on a calling side.

[0018]

According to the present invention, there is provided a telephone having automatic line connection means for executing automatic line connection upon receiving an incoming call, and notification means for performing a notification operation upon receiving the incoming call. Delay means for delaying the notification operation for a fixed time, and when receiving predetermined control information sent from the sender during the delay by the delay means, controls the notification operation by the notification means based on the control information; And notifying control means for controlling a notifying operation of the notifying means based on a preset initial setting when the predetermined control information sent from the caller is not received during the delay by the delay means. Features.

Further, according to the present invention, in the above configuration, a recording means for automatically recording a voice message transmitted from the transmitting side, and a voice output control means for controlling a speaker output level of the voice message transmitted from the transmitting side. Further comprising, when receiving predetermined control information sent from a caller during the delay by the delay means, executes an automatic recording operation by the recording means and sets a speaker output level by the audio output control means. It is characterized by being controlled to zero.

[0020]

According to the present invention, when an incoming call is detected, the automatic line connection means controls the automatic line connection with the calling side, and the delay means delays the notification operation by the notification means for a certain period of time. When the predetermined control information is received from the calling side within the delay time, the notification operation by the notification unit is controlled based on the control information, and when the predetermined control information is not received from the caller within the delay time. Is
The notification operation by the notification means is controlled based on the initial setting.

[0021] Further, recording means for automatically recording a voice message transmitted from the transmitting side, and voice output control means for controlling a speaker output level of the voice message transmitted from the transmitting side are further provided. When the predetermined control information transmitted from the caller is received, the automatic recording operation is performed by the recording means and the speaker output level is controlled to zero by the sound output control means.
