Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone device capable of making a telephone call by a wired telephone in a place where there is no wired telephone line.

[0002]

2. Description of the Related Art In recent years, a cordless telephone apparatus using wireless transmission has been used instead of a curl code between a telephone body and a handset. The cordless telephone device replaces the curl code between the telephone body and the handset of a conventional wired telephone with wireless transmission, and replaces the portion corresponding to the conventional telephone body with the portion corresponding to the cordless telephone master unit and the handset. It is called a cordless phone handset.
A cordless telephone handset can be used to make and receive calls around a cordless telephone base unit installed in a home or office (generally within a radius of several hundred meters), and a wired telephone line is wired. Wired phones can be used even in rooms where there is no room.

[0003]

[Problems to be Solved by the Invention] However, in the past,
When a user who used a wired telephone purchases and uses the above-described conventional cordless telephone device, there are the following problems.

First, the existing wired telephone that has been used conventionally cannot be used. Next, the usage of the cordless telephone device is different from that of the wired telephone, and there is a problem that it is difficult for a user who is not used to a cordless telephone to use it. This is because when making a call with a wired telephone, for example, you can pick up the handset (this is called off-hook) and enter the telephone number (this is done by dialing or push button), whereas with the cordless telephone device, This means that it is necessary to enter the telephone number after pressing the call button on the child device.

The present invention solves the above-mentioned problems, and the existing wired telephone that the user has conventionally used can be used as it is without waste, and the room is not wired. It is an object of the present invention to provide a cordless telephone device that can use telephone calls by wired telephone.

[0006]

In order to solve the above problems, a cordless telephone device of the present invention converts a received signal from a wired telephone line into a radio high frequency signal for transmission and reproduces it from the received radio high frequency signal. A wired telephone line adapter for transmitting the line signal to the wired telephone line, and a telephone signal reproduced from the wireless high frequency signal received from the wired telephone line adapter to the wired telephone, and a transmission signal from the wired telephone is wirelessly transmitted. It is composed of a wired telephone adapter that converts to a high frequency signal and transmits.

[0007]

With the above configuration, the wired telephone line adapter connected to the wired telephone line functions as a cordless telephone master unit that communicates with the cordless telephone slave unit via a radio high-frequency signal, and is connected to the wired telephone. The adapter
By working as a cordless telephone handset that communicates with the cordless telephone base unit via a radio high frequency signal, a cordless telephone call is made.
