JPH0630086A - Incoming call display device for telephone set - Google Patents

Abstract

PURPOSE:To notify the arrival of an incoming call when it arrives and to clearly indicate an operating key to receive the incoming call. CONSTITUTION:When the incoming call arrives via a telephone line 8, since a signal is sent from a line closure control part 5 to an illumination lighting circuit 3, and a lamp 2 is lighted, a speech start key 1a is illuminated. Therefore, a user can recognize an incoming call receiving state by light, and also, where abouts of the speech start key 1a to be operated to receive the incoming call by observing the lighting of the key.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call display device for a telephone.

[0002]

2. Description of the Related Art Conventionally, an incoming call display device of this type is configured to turn on an incoming call lamp of a telephone when an incoming call is received. Therefore, it is possible to know by light that the telephone is in the incoming state.

[0003]

However, in the above-mentioned conventional incoming call display device, when an incoming call is received, the incoming call lamp of the telephone is turned on. Therefore, it is possible to know by light that the incoming call is in progress. When a person who is not familiar with the operation method of (1) receives an incoming call, there is a problem that he or she does not know which key should be pressed to make a call.

The present invention is intended to solve such a conventional problem, and an object of the present invention is to provide an excellent incoming call display device capable of knowing an incoming call and clarifying a key to be operated.

[0005]

In order to achieve the above-mentioned object, the present invention provides a key illumination lamp for a call start key, and when a call arrives, only the call start key is lit in response to an incoming signal. It is the one.

[0006]

Therefore, according to the present invention, by illuminating only the call start key at the time of an incoming call, it is understood that it is sufficient to press the call start key in order to receive the incoming call at the same time as knowing the incoming call. It is possible to prevent the failure to receive an incoming call due to the operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 1 is a key operation unit having a call start key 1a, 2 is a lamp for lighting only the call start key 1a, 3 is an illumination lighting circuit, 4 is a communication circuit, and 5 is a circuit for realizing a calling / receiving means. A closing control unit, 6 is a receiver, 7 is a transmitter, and 8 is a telephone line.

Next, the operation of the above embodiment will be described.
In the above embodiment, when an incoming call is received through the telephone line 8, an incoming signal is sent from the line closing control unit 5 to the communication circuit 4, a ringing tone is emitted from the handset 6 and the circuit closing control unit 5 lights up the illumination. A signal is sent to the circuit 3 and the lamp 2
Light up. As a result, the user who knows the incoming call by turning on the call start key 1a can receive the incoming call and press the call by pressing the call start key 1a.

As described above, according to the above embodiment, when an incoming call is received, a signal is sent from the circuit closing control section 5 to the lighting circuit 3, and the lamp 2 is turned on to illuminate the call start key 1a. The user can know the incoming call by light and the location of the call start key 1a to be operated to receive the incoming call by looking at the illumination of the key.

In the above embodiment, the lamp 2 at the time of receiving an incoming call may be blinked in synchronism with the ringing sound produced by the handset 6. In this case, the illumination of the call start key 1a is more noticeable.

[0011]

As is apparent from the above embodiment, the present invention makes it possible to light only the call start key when receiving a call.
There is an effect that the incoming call can be known by light and the location of the call start key to be operated when receiving the incoming call can be clearly indicated.

Further, according to the present invention, by clearly indicating the operation start key to be operated when receiving an incoming call, a user who is not familiar with the operation of the telephone operates the wrong key to receive the incoming call. This has an effect of preventing failure to receive.
