Abstract

PURPOSE:To attain part of the functions of a cordless telephone set and to facilitate installation work by attaching a radio equipment to a conventional telephone set. CONSTITUTION:In the event of receiving a call of a conventional telephone set, a master set 1 detects a call tone by a sensor 63, a control section 17 sends an incoming signal to a transmission section 13 to give a signal to a slave set 2. The slave set 2 receives an incoming signal, demodulates it by a reception section 24 to ring an incoming tone from 2 speaker 27 to inform it to the user. when the user depresses a hook switch 71 of the slave set 2, a control section 29 sends a reply signal to a transmission section 23, from which the signal is sent to the master set 1. A reception section 14 of the master set 1 demodulates the received reply signal, sends the result to the control section 16, which drives a switch 19 in case of the reply signal and the switch 19 controls the hook switch of the conventional telephone set to enable the communication. Thus, the existing telephone set is utilized to enable part of the functions of the cordless telephone set and the installation work is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio device that is added to a general telephone to realize a telephone without a curl cord.

[Conventional technology and issues to be solved by call center aA] Conventionally, the installation location of regular telephones was fixed by telephone lines, which caused inconvenience especially when the user was far away from the regular telephone. there were. Cordless telephone as a means to solve the problem [Another means to solve the problem] In the wireless device according to the present invention, the base unit has a structure that can be installed between the handset part and the casing part of the general telephone set, has a means for detecting the incoming call when the handset receives a call, and a transmitting means for notifying the handset of the incoming call; The handset has means for notifying an operator of an incoming call from the base unit, and has means for sending a response signal to the base unit in response to an operation from the operator. are doing.

〔Example〕

Next, the present invention will be explained with reference to FIGS. 1 and 2.

FIG. 1 shows a telephone-attached wireless device according to the present invention installed in a general telephone.

The base unit 1 can be installed between a handset 3 and a housing 4 of a general telephone. A curl cord 5 connects the handset 3 and the housing 4. The handset 2 has an external shape comparable to or smaller than the handset 3 so that the user can carry it and use it.

FIG. 2 shows an example of a block diagram of a wireless device attached to a telephone according to the present invention.The operation will be explained with reference to FIG.

When the base phone 1 receives an incoming call from a regular telephone, for example, a sensor 63 that detects a ringing tone detects the incoming call, and the first control unit 17 sends an incoming call signal to the transmitting unit 13.

It is transmitted to the slave unit 2 via the antenna 11. The handset 2 receives the incoming signal through the receiving antenna 22, demodulates it through the receiving section 24, and sounds a ringing tone through the speaker 27 to notify the user of the incoming call.

When the user recognizes that there is an incoming call, he presses the hook inch 7■ on the handset 2. The control section 29 detects this and sends a response signal to the transmitting section 23, which in turn sends the response signal to the antenna 21 and the base unit 1.

In base device 1 , a response signal received by reception antenna 12 is demodulated by reception section 14 and sent to second ftflJ control section 16 . The second control unit 16 identifies the received signal and drives the switch 19 if it is a response signal. The switch 19 controls the hook inch of the general telephone to make it possible to make a call.

The voice signal from the general telephone is coupled to the micro 1 of the main unit 1 through the receiver 31 of the handset 3 of the general telephone, transmitted through the transmitter 13 to the handset 2, and used through the receiver 27t of the handset 2. communicated to others.

Voice from the user is sent to the transmitting unit 23 through the microphone 26 of the handset 2, and then to the base unit 1 through the antenna 21. The voice signal demodulated by the receiving unit 14 of the base unit 1 is converted into a voice signal through the receiver 60, coupled to the microphone 32 of the handset 3 of the general telephone set, and transmitted to the other party.

〔Effect of the invention〕

As explained above, the wireless device according to the present invention has the advantage that it can be used as a cordless telephone by using an existing telephone, and that the installation work is easy.
