Abstract

PURPOSE:To prevent trouble by a call tone in wrong dial or mischievous call by answering automatically an answer message once to a telephone call from an external telephone set, sending and notifying a call tone after the presence of reply is confirmed. CONSTITUTION:A time is set at a trouble prevention function operating set time. An output of a timer 6 changes over a changeover relay 4 and a call signal from a general public telephone line 2 is inputted to a call signal reception circuit 8 via an automatic incoming relay 7. When the circuit 8 receives a call signal for a prescribed time or over, the relay 7 is driven, a terminal C2 is connected to a contact B2 to set the automatic incoming state. Further, the output of the relay 7 is inputted to an automatic answer circuit 9 to transmit an inquiry voice recorded in advance to the caller automatically. When no answer comes within a prescribed time from the opposite party, an answer confirming circuit 10 allows the circuit 9 to send a message again. When an answer comes, a call tone generating circuit 5 is driven by a drive circuit 11 to send the call tone.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a telephone, and particularly to a telephone with a nuisance prevention function that can prevent nuisance due to troublesome or unpleasant calls such as mistaken calls and prank calls. .

[Prior Art] Fig. 2 shows the configuration of a conventional telephone to generate a ringing tone, in which (1) is a telephone, (2) is a general public telephone line connected to the telephone (1), and (3) is a telephone. The ring tone generation circuit is built into the telephone (1).

The ringing signal from the outside telephone is transmitted via the general public telephone line (2) to the ringing tone generating circuit (3) built into the telephone (1).
A ringtone is sent out, indicating that a call has been received from an outside telephone.

[Problems to be Solved by the Invention] Since the conventional telephone set is configured as described above, when an outside call is received, it is necessary to answer the telephone even when the person calls by mistake. In addition, there have been problems such as sleep being disturbed by the ringing of the wrong phone from an unwanted person, especially late at night.

The present invention was made in order to solve the above-mentioned problems, and the present invention automatically answers a call from an outside telephone with an unresponsive message, and only sends a ring tone after confirming that there is a response. The purpose of the present invention is to obtain a telephone with a nuisance prevention function capable of giving notifications.

[Means for Solving the Problems] In order to achieve the above object, the present invention receives a calling signal from a general public telephone line at a time set by a timer and automatically receives the call. The system automatically answers the call by indicating the destination of the call to the other party via a public telephone line, and after confirming the response from the other party, the telephone rings.

[Function] As is clear from the configuration described above, according to the present invention, when a ringing signal is received from a general public telephone line, a ringing tone cannot be immediately transmitted within the time set by the timer. In addition, the incoming call is automatically answered by the other party, and the voice recognition circuit identifies the answering sound from the other party before sending out the ringtone, eliminating the troublesome task of answering the telephone in case of a wrong call or a prank call. disappears.

[Example] Preferred embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows the configuration of an embodiment of a telephone with a nuisance prevention function according to the present invention, and a timer (6) is a timer for setting the time to activate the nuisance prevention function, and its output is It is connected to the switching relay (4). and,
A general public telephone line (2) is connected to the terminal C1 of the switching relay (4).

When the nuisance prevention function is not activated, terminal C1 of the switching relay is connected to contact B1, and the operation is the same as in the conventional example.
A ringing signal from the general public telephone line (2) drives a ringing tone generation circuit (5) to output a ringing tone.

On the other hand, at the nuisance prevention function activation set time d3, the output of the timer (6) causes the call signal from the general public telephone line (2) to be transferred to the automatic incoming call relay via the contact A1 of the switching relay (4). The signal is input to the calling signal receiving circuit (8) via terminals C2 and A2 of (7).

When the calling signal receiving circuit (8) receives a calling signal for a certain period of time or more, the automatic incoming call relay (7)
), and this output signal connects the terminal C2 of the automatic incoming call relay (7) to the contact B2, resulting in an automatic incoming call state.

In addition, the output of the automatic incoming call relay (7) is the automatic antenna circuit (
9), and the voice indicating the destination recorded in advance and the voice of the question are automatically sent out from the automatic announcer circuit (9) to the other party who calls through the general public line (2). Ru.

The response confirmation circuit (10) is an automatic unrecovery circuit (9).
), and if there is no response within a certain period of time, an output signal is generated to the automatic announcer circuit (9), and the automatic announcer circuit (9) sends a message again. If there is a response within a certain period of time, the response confirmation circuit (10)
generates an output signal to the drive circuit (11), drives the ringing tone generation circuit (5), and sends out a ringing tone.

In the above embodiment, the configuration is shown as being built into the telephone, but the ring tone generation circuit, etc. may be installed in a separate unit from the telephone.
Even if it is provided in ~, the same effect as in the above embodiment can be obtained.

[Effects of the Invention] As explained above, according to the present invention, a switching relay connected to a timer is configured to automatically receive, answer, and confirm calls received from an outside telephone. The ringtone will not be emitted into the room in case of a wrong call or a prank call, so the ringtone will not interfere when you are busy doing housework or at times set on a timer, such as while you are sleeping. You can get some effect.
