Abstract

PURPOSE:To easily detect the arrival of a call to a terminal equipment even from a noisy location or a location remote from the terminal equipment by allowing the incoming call detector to send a remote signal in a radio channel when the incoming call comes to the terminal equipment and allowing an incoming call display device receiving the signal to light its light emitting section. CONSTITUTION:An incoming call detector 1 is connected to an idle modular jack MJ to which a telephone set T is connected. On the other hand, an incoming call display device 3 is arranged so as to receive a radio wave sent by the detector 1. When an incoming call signal comes to the telephone set T, the detector 1 detects the incoming call signal and allows its transmission antenna 2 to send a radio wave. The incoming call display device 3 receives the radio wave by its reception antenna 4 and lights its light emitting section 5.

And an incoming call display device having a light emitting section that is turned on.

According to another aspect of the present invention, there is provided an incoming call detecting system according to claim 1, wherein the incoming call detecting device according to claim 1 is connected to a unique line assigned to the terminal by a modular jack. The detection system is configured by adding a sounding unit that emits a sound when a remote signal is received, to the incoming display device according to the first or second aspect.

[0007]

According to the structure described in claim 1, when an incoming call is received by the terminal, a remote signal is wirelessly transmitted from the incoming call detection device and the incoming call display device receiving the remote signal lights the light emitting portion. Therefore, the incoming call to the terminal can be easily detected even in a noisy place or a place far from the terminal.

According to the configuration of claim 2, in addition to the operation of claim 1, since the incoming call detecting device is connected to the unique line assigned to the terminal by a modular jack, the incoming call detecting device is attached or detached. Can be performed easily and simply.

According to the third aspect of the invention, in addition to the operation of the first or second aspect, since the incoming call display device is provided with a sounding section that emits a sound upon receiving a remote signal, it is easier to connect to the terminal. Can detect incoming calls.
