Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an incoming call system that notifies a telephone of an incoming call when a call is received, and particularly relates to an incoming call system for a cordless telephone using radio.

[Conventional technology]

Conventional incoming call methods include one in which the telephone emits a ringtone when a call arrives to notify the telephone user of the incoming call, and one in which the lamp on a desk lamp or the like flashes to notify the user of the incoming call.

[Problem to be solved by the invention]

The conventional incoming call system described above has the following drawbacks.

(b) In a system in which a ringer is emitted to notify the user of an incoming call, if the telephone is located in a noisy place or the user is present, the user cannot hear the ringer. Also,
Even in a quiet place, a hearing-impaired user cannot hear the ringing tone unless he or she is next to the telephone.

(b) In a system in which a lamp such as a desk lamp flashes to notify an incoming call, if the lamp flashes in the daytime or in a bright place, it is difficult to distinguish whether the lamp is flashing or not. Furthermore, if the user is facing away from the lamp or in a room different from the room where the lamp is located, the user may not notice the flashing of the lamp.

Features.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an incoming call system according to an embodiment of the present invention.

In the incoming call system of this example, a handset 1 and a cordless telephone body 2 are connected from a terminal 3 to an exchange 4. When an incoming call is received via the subscriber line 5, a wireless portable incoming call device 6
This method notifies the recipient of the incoming call.

The telephone main body 2 has an incoming call circuit 7, a bell 8, and a transmitting/receiving circuit 9.

The incoming call circuit 7 has an input side connected to the subscriber line 5, and an output side connected to the bell 8 and the transmitting/receiving circuit 9. This incoming call circuit 7 has the function of inputting an incoming call signal a sent via the subscriber line 5, causing the bell 8 to ring, and outputting an instruction signal S to the transmitting/receiving circuit 9.

The transmitting/receiving circuit 9 has an incoming signal oscillator 1o. This transmitting/receiving circuit 9 has a function of operating an incoming signal oscillator 10 based on an instruction signal from the incoming call circuit 7. The incoming signal oscillation unit 10 is for oscillating the incoming signal C into space via the antenna 11. Further, this transmitting/receiving circuit 9 has a general function of transmitting and receiving calls. That is, by receiving the call start signal d from the handset 1, it sends a control signal to the exchange 4 to stop sending the incoming call signal a and establish a call state with the terminal 3. , has a function of transmitting and receiving a call signal e to and from the handset 1 during a call.

The incoming call device 6 includes a receiving circuit 1 having an antenna 12.
4 and a buzzer 15 connected to the receiving circuit 14.

The receiving circuit 14 has a function of receiving the incoming signal C via the antenna 12 and causing the buzzer 15 to sound simultaneously with the reception.

The handset 1 is for communicating with the terminal 3 via the transmitting/receiving circuit 10 . The handset 1 also has a function of oscillating the signal d to the transmitting/receiving circuit 9 of the telephone main body 2 to notify the start of a call by turning on a call switch (not shown).

Next, the operation of this embodiment will be explained.

When a call is made to the telephone body 2 from the terminal 3,
An incoming call signal a is input from the exchange 4 to the incoming call circuit 7 via the subscriber line 5.

The incoming call circuit 7 to which the incoming call signal a is input rings the bell 8 of the telephone body 2 and sends an instruction signal to the transmitting/receiving circuit 9.
Output to. If the user is near the telephone main body 2, the user can be informed of the incoming call by the ringing of the bell 8.

The transmitter/receiver circuit 9 to which the instruction signal is input operates the incoming signal oscillator 10 . An incoming signal C is oscillated from the incoming signal oscillator 10 to the incoming paging device 6 via the antenna 11 .

The incoming call signal C is sent to the incoming call device 6 via the antenna 12.
It is received by the receiving circuit 14 of. The receiving circuit 14 that has received the incoming signal C causes the buzzer 15 to sound based on the incoming signal C.

A user carrying an incoming call device 6 can use the buzzer 15.
This allows you to know the fact that a call has arrived.

When the user turns on the call switch of the handset 1 to accept a call, a call start signal d is oscillated from the antenna 13 of the handset 1 toward the telephone body 2. The transmitter/receiver circuit 9, which has received the signal d via the antenna 11, sends the control signal requesting the exchange 4 to stop sending out the incoming call signal a and establish a call state with the terminal 3.

The exchange 4 that received this control signal transmits the incoming call signal a
The transmission of the message is stopped and at the same time the communication status is established.

Further, the incoming call circuit 7 detects that there is no human power for the incoming call signal a, and outputs an instruction signal to stop the oscillation of the incoming call signal C to the transmitting/receiving circuit 9. The transmitter/receiver circuit 9 to which this instruction signal is input stops the operation of the incoming signal oscillator 10.

In the incoming call calling device 6, since the incoming call signal C is not received by the receiving circuit 14, the buzzer 15 stops ringing.

Thereafter, the user can use the handset 1 to talk to the terminal 3.

In this embodiment, a bell 8 is used on the telephone main body 2 as a means for indicating a call, and a buzzer 15 is used as an incoming call signal 6, but the present invention is not limited to this. A lamp or the like may be used instead of the bell 8, or a lamp or the like may be attached to the telephone main body 2 together with the bell 8. It is obvious that a lamp or the like may be used instead of the buzzer 15, or a lamp or the like may be attached together with the buzzer 15.

〔Effect of the invention〕

Since the incoming call system of the present invention is configured as described above, it has the following effects.

(b) Since the incoming call device carried by the user displays a call nearby, even if the user or the telephone is in a noisy place, the user can be sure of the fact that there is an incoming call.

(b) By carrying an incoming call device, it is convenient for hearing-impaired users to be able to recognize incoming calls.
