Abstract

PURPOSE:To cancel a trouble to an unnecessary telephone call by acoustically calling from a specified opponent destination and optically calling from the other unspecified many opponent destinations. CONSTITUTION:When a calling signal is sent through a subscriber line 10, this signal is detected by a call detecting circuit 4 and a lamp 5 is turned on. The calling is also informed of a control circuit 9 and a hooking circuit 3 is activat ed by the control circuit 9. After a constant time passes, by activating a voice synthesizing circuit 6, the telephone calls from the unspecified many opponents are shut out. To the specified opponent destination, after off-hook, it is informed in advance to push a specified PB button. Accordingly, since a PB signal is sent from the specified opponent destination, at the time of the off-hook, the PB signal is detected by a PB detecting circuit 7 and a calling tone is sent from a bell 8. Thus, an instant response can be executed to the specified oppo nent destination.

Description

[Detailed Description of the Invention] (Field of Application of Mado) The present invention relates to telephones, and does not play a ringing sound when receiving calls from an unspecified number of people, but only when receiving calls from a specific person. Even my best friends are concerned about phone calls and measures against interruptions caused by calls during busy times.

(Prior art) Although nine telephones equipped with various functions have been put into practical use,
One of them is to automatically answer incoming calls when you are away,
Let the other person know that you will be away.

Answering machines are known that ring the caller's requirements.

(Problem to be solved by the invention) However, with an answering machine, it is not possible to determine whether the call is from a specific person who wants to make an immediate call, or whether the call is from an unspecified number of people who do not require an urgent call. The company used an answering machine to respond to calls, which had the disadvantage of not being able to respond differently depending on the caller.

The object of the present invention is to overcome the above-mentioned drawbacks.

We will provide a telephone that allows you to use the answering machine function to answer non-emergency calls without ringing the bell, and to ring the bell and answer the callers directly by dialing a specific FB double signal. be.

(Means for Solving the Problems) In order to achieve the above object, the telephone according to the present invention includes an optical calling means that detects a calling signal and optically notifies the user of the call, a hooking circuit that performs off-hook and on-hook operations, and a predetermined system. audio output means for outputting sound; ringing tone generation means for generating a ringing tone when a PB double signal is detected; The device may be configured to include a control circuit that enables operation upon arrival of a signal, and when the FB double signal does not arrive within a certain period of time, activates the audio output means to transmit audio to the calling side, and then performs on-hook control. be.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of a telephone according to the present invention.

When a call signal is sent from a telephone office (not shown) through the subscriber line 10, the call detection circuit 4 detects this and lights up the lamp 5. The control circuit 9 is also notified of the call, and the control circuit 9 activates the hooking circuit 3 to take it off-hook. After a certain period of time has elapsed, the voice synthesis circuit 6 is activated and an announcement is made to the caller, such as ``I cannot answer the phone right now, so please fix the call later.''
After that, the hooking circuit 3 is activated to be on-hook.

Telephone calls from an unspecified number of people will be shut out by the above operation.

Next, the case of a specific opponent will be explained.

A specific destination is notified in advance to press a specific PB button after going off-hook.

Therefore, since a PB double signal is sent from the specific party, when off-hook, the connected PB detection circuit 7 detects the FB double signal, and a V ring tone is sent to the bell 8.

This makes it possible to respond immediately to a specific destination.

The telephone circuit 2 is a conventional telephone with the ringing bell removed. .

The optical paging means is a part including a paging detection circuit 4 and a lamp 5, and the ringing tone generating means is a circuit part including a PB detection circuit 7 and a bell 8.

PB double signal for detecting a specific destination Not only is a specific FB double signal sent once, but multiple times, and different F
A combination of B times signals may also be used.

Further, the voice synthesis means is not limited to the voice synthesis circuit 6, but may be of a reproducing type, and the voice synthesizing means may be of a bell reproducing type.

The generating section of the ringing tone generating means is not limited to the bell 8, but may be any device that emits a swooshing sound #.

(Effects of the Invention) As explained above, the present invention allows calls from a specific destination to be made acoustically, and calls from a large number of unspecified destinations to be called optically. This has the effect of not being bothered by unnecessary calls.
