JPS63227157A - Telephone set equipped with calling indicator - Google Patents

Abstract

PURPOSE:To vidually confirm the call of an extension or a line wire by providing an indicator displaying visually the fact of an extension or line wire calling. CONSTITUTION:A telephone signal from the terminal 7 of a telephone set is received by a telephone set main body 2 and communication is executed by a receiver 4. Also, a line wire calling instructing signal which is usually sent out of a private branch exchange is received by a terminal 6, its signal is discriminated by an extension/line wire discriminator 1, and based on the result of its discrimination, the extension or the line wire is displayed by the indicator 3, and also, by a loudspeaker 5 for a call tone signal use, a line wire or extension call tone from the body 2 is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone set connected to a local telephone system, and more particularly to a telephone set having a call display function.

[Conventional technology]

Conventionally, this type of telephone set calls for internal/external calls by varying the intermittent ringing cycle or by selecting and ringing a ringing tone based on an outside line or extension call instruction signal from a private telephone device (switchboard). I was going.

[Problem that the invention seeks to solve]

In the above-mentioned calling method based on the difference in intermittent cycle and ring tone, experience is required to hear the difference in intermittent cycle and ring tone. has the problem of not being able to distinguish between internal and external calls, and having to be very careful when answering calls.

Additionally, in workplaces with high traffic, people often pick up the handset after just one ring due to the psychological state of being ``noisy'' due to the constant ringing, and there is also the problem that the functions of the above-mentioned paging system are not fully utilized. be.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a telephone with a call display that allows the user to visually confirm an outside line or extension call.

[Means for solving problems]

The telephone set of the present invention has means for visually displaying an internal/external call call in response to an internal/external line instruction signal from the local telephone device.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of a telephone according to the invention.

In FIG. 1, the telephone of the present invention has a configuration in which the telephone main body 2 receives a telephone signal from a terminal 7, and a telephone receiver 4 makes a call.Furthermore, an outside line call instruction signal, which is normally sent from a private branch exchange, is received at a terminal 6. After receiving the signal, the extension/external line discriminator 1 discriminates the signal, and based on the discrimination result, the display 3 displays the internal line or external line, and the ring tone signal speaker 5 detects the external line or external line from the telephone body 2. It is configured to emit a ringing tone.

FIGS. 2(a) and 2(b) are a top view and a side view of an example of the display device 3, respectively. The display 3 has a structure in which green and red light emitting diodes 3a and 3b are arranged in parallel and bonded together, and is driven by the extension/external line discriminator 1. When the extension/external line discriminator 1 determines that the call is an outside call or an extension call, green and red light emitting diodes are turned on, respectively, in this example. This display 3 is attached to the front of the telephone main body 2 at an easily visible position.

Therefore, the receiver can simply look at the lighting color of display 3.
You can check external or internal lines.

It goes without saying that a call can be started by turning on the telephone. Furthermore, if it is desired to operate only the display device 3, the speaker 5 may not be driven by a switch or the like.

〔Effect of the invention〕

As explained above, the telephone of the present invention is provided with a display that visually indicates whether the call is an internal or external call, and by driving the display after distinguishing with the extension/external line discriminator, the user can call the telephone. This has the effect of making it possible to clearly distinguish between internal and external calls without having to listen to the dial tone over and over again.
