Abstract

PURPOSE:To display the telephone number of a transmitting source on a display part before a receiver is picked up by installing a telephone number transmitting part and a telephone number identifying circuit to respective telephone systems. CONSTITUTION:In a selecting signal transmitting means 10, a telephone number transmitting part 10B to output a signal to succeed to the transmission of a selecting signal and to relate to the telephone number of a transmitting source is provided and in a receiver circuit 11, a telephone number identifying circuit 1A to identify a signal to relate to the telephone number of the transmitting source sent from the transmitting source and a display part 1B to display the telephone number of the transmitting source identified by this telephone number identifying circuit 1A are put side by side. When a dialing is finished and a calling condition is set, the telephone number transmitting part 10B is operated, repeats the telephone number of a transmitting side and transmits it via a PBX to a receiving side. Thus, the telephone number identifying circuit 2A of the receiving side is operated, the telephone number of the receiving side is recognized, distinguished and displayed on a display part 2B.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone device, and more particularly to a telephone device that allows a receiving side to recognize a calling party's telephone number.

[Conventional technology]

Traditionally, the method on which the receiving side knows the calling party's phone number is as follows:
The mainstream method is so-called reverse detection during a call.

[Problem that the invention seeks to solve]

However, in the conventional example described above, the source of the call is detected by tracing the circuit from the receiving side, assuming that the call will continue. Therefore, there is a drawback that detection requires a relatively long time.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to improve the disadvantages of the conventional example and to provide a telephone device that simultaneously sends signals related to the telephone number of the caller to the receiving side.

(Means for Solving the Problems) The present invention includes a selection signal transmitting means for outputting a selection signal to a predetermined receiving side telephone, and setting a telephone line to a conductive state in response to the output of the selection signal transmitting means. and a receiver circuit. The selection signal transmission means is provided with a telephone number transmission section that outputs a signal related to the telephone number of the caller following transmission of the selection signal. The receiver circuit includes a telephone number identification circuit that identifies a signal related to the telephone number of the caller sent from the caller, and a display section that displays the telephone number of the caller identified by the telephone number identification circuit. The structure is such that it is attached to the building. This aims to achieve the above-mentioned purpose.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG.

In the embodiment shown in FIG. 1, the originating telephone 1 and the receiving telephone 2 are identically constructed. A private branch exchange telephone (
PBX) 3 is equipped.

The originating telephone 1 includes a selection signal transmitting means 10 that outputs a selection signal to a predetermined receiving telephone, and a receiver circuit 11 that sets the telephone line to a conductive state in response to the output of the selection signal transmitting means 10. have.

The selection signal transmitting means 10 includes a dial IOA and necessary circuits attached thereto, as well as a telephone number transmitting section 10B,
It has a switch IOC for electrically disconnecting the telephone number transmitting section 10B from the circuit. The telephone number transmitter 10B is set to be ready for output when the dial IOA is started, and is configured to send a signal to the other party following a signal related to the selected telephone number of the other party.

Then, when the telephone 2 of the other party is selected, the signal related to the telephone number of the caller is simultaneously identified by the telephone number identification circuit 2A of the telephone 2 of the other party, and the number is displayed on the display section 2B. It has become.

The originating telephone 1 also has a telephone number identification circuit IA and a display section IB that are constructed in the same way as the telephone 2 and function in the same manner.
is equipped with.

In addition, as in the case of the telephone 1 described above, the receiving telephone 2 includes a selection signal transmitting means 20 for outputting a selection signal to other telephones including the calling telephone 1, and a selection signal transmitting means 20 of the selection signal transmitting means 20. and a receiver circuit 21 that sets the telephone line to a conductive state in response to the output.

Next, the operation of the above embodiment will be explained.

When the other party's telephone number is dialed using the dial 10A, the telephone number transmitter 10B is activated. Once dialing is complete and the ring state is set for the recipient,
The telephone number transmitter 10B operates and repeatedly transmits the transmitter's telephone number to the receiver through the PBX. This activates the telephone number identification circuit 2A on the receiving side and recognizes the calling party's telephone number.

It is determined and displayed on the display section 2B.

On the receiving side, when the calling party's telephone number is confirmed on the display section 2B and the telephone receiver 21 is picked up, the telephone line is automatically connected and a conversation becomes possible.

Note that the calling side telephone number transmitting unit 10B is shown as an example built in the telephone 1, but the telephone number transmitting unit 10B of the calling side
It is also possible to add it to BX.

〔Effect of the invention〕

As described above, according to the present invention, the telephone number of the caller is displayed on the display section before picking up the handset by the action of the telephone number transmitting section and the telephone number identification circuit provided in each of the telephones of the caller and the receiver. This is effective in preventing prank calls, wrong calls, malicious solicitations, etc. Furthermore, the receiver is able to recognize the caller and answer the call, which is an unprecedented and superior telephone device. can be provided.
