Description

Keyphone Type Wire / Wireless Telephone Device {Keyphone Type Wire-based and Wireless Telephone System}

The present invention relates to a keyphone type wired / wireless telephone. More specifically, the key phone type wireless telephone apparatus is divided into a repeater (I), a cordless telephone (II), and a wired telephone (III), and a key phone type for preventing crosstalk when used by multiple users by adding a wired communication unit to the repeater. It relates to wired / wireless telephones.

In general, a key-phone type landline telephone used in an office is configured to be connected by a wired telephone line, so it is inconvenient in that a telephone construction must be renewed every time the installation of the office is changed. In addition, as the telephone line is exposed to the outside, a poor connection failure due to an external shock occurs frequently.

However, due to the development of information and communication technology, a wireless telephone that overcomes the shortcomings of the wired telephone has been developed, which adds a lot of convenience. In the case of a conventional wireless telephone, a single telephone can be used by several people by connecting a plurality of handsets to a single main body. However, as all functions are integrated into a handset of a radiotelephone and increasingly smaller and lighter, they are not suitable for use in office or home reception sets. In addition, even when the main body is mounted, a telephone line and a DC power supply line are required, which causes many problems in terms of layout and space utilization. In particular, wireless modems are being used in accordance with the spread of communication devices such as computers, but they are not widely used as telephones because they are inconvenient to use and unsuitable for voice calls.

In order to solve the above problems, the present inventor connects a transmission and reception relay device to a telephone line and configures a cordless telephone corresponding thereto such that a receiver and a main body are connected by a coil cord to a cordless telephone. It was filed in 97-23515. By devising the handset-type cordless telephone in the form of a corded telephone with a cord cord, it is possible to solve the problem of being inconvenient to place in the reception set of the office and home, and to expand the dial keyboard to make it easier for the elderly to use. You can design the product in the form.

In addition, the present inventors install the wireless telephone line transmission / reception relay device of the whole line and the corresponding wireless telephone in the terminal box and expand the call forwarding function by adding the decoding circuit of the line switching device to expand the function for the office. Filed with a domestic phone application No. 97-50759. Particularly, in an office environment such as a conference room, the telephone should be fixed stably, so a cordless telephone in the form of the above-described device is preferable, and a key-phone type wireless telephone apparatus that inserts a card-type transceiver into a terminal box by eliminating the telephone wiring of the office. Has the form of.

However, the key-phone type wireless telephone according to the above design can use up to 30 people and simultaneous calls, but up to 10 people can use the phone because the bandwidth is limited. In addition, there is a technical difficulty in initializing the transmission and reception relay device, it is inconvenient to control when the relay device is installed, and in the computer communication, the wireless method is less reliable in communication than the wired method.

In order to overcome the above problems, the present inventors have developed a wired / wireless telephone apparatus that is a mixture of wireless and wired methods so that a telephone that needs to communicate by wire can be connected by wire.

An object of the present invention is to provide a key-phone type wired / wireless telephone device that allows a user who does not need to connect wirelessly by adding a wired communication function to a transmission / reception relay device, and a user who cannot use a telephone line. It is to.

Another object of the present invention is to provide a key-phone type wired / wireless telephone apparatus that can overcome the problem of crosstalk caused by use by a large-scale user and the difficulty of initiating a transmission / reception relay.

Still another object of the present invention is to provide a key-phone type wired / wireless telephone apparatus that can use a wireless telephone by installing a wireless transmission / reception circuit module in a wired transmission / reception portion of a key phone installed in an existing office.
