Key-board phone for the computer}

The present invention relates to a phone for a key board, and more particularly, when a telephone call is being made while using a computer in a place such as an office, a telephone and switches are provided integrally with the key board. The present invention relates to a phone for a keyboard for making a call without a handset.

Nowadays, due to the development of information technology, almost every individual installs a computer in an office or a laboratory to handle all the work. Due to the development of communication technology, one or more telephones are installed in each desk to be used for work.

Therefore, in the office or research lab, the computer is used again while using a general business telephone or a cordless telephone. For this purpose, the wiring for forming a telephone call path, the power line for powering the computer, and the communication lines for computer communication are used on one desk. Should be installed in

In addition, since a hard box of a computer, a device for a computer of a monitor, a key board, and a printer, as well as a telephone must be installed on a single desk, the installation space is limited due to the small space of the desk, and the worker who uses the computer. When the user makes or receives a call, the handset must be secured by the shoulder and neck while the computer's key board is operated with both hands.

Therefore, in order to solve the above-mentioned problems, access the mouse by adding a phone function to the mouse or by installing an additional handset and receiver on the keyboard to use the phone of the mouse or the phone of the keyboard while using the computer. It was made.

However, the conventional method of installing a telephone on the mouse or key board as described above has the advantage that the desk can be used more widely than the case of separately installing the computer and the telephone, while simultaneously using the computer and the telephone. There is a disadvantage.

That is, in the case of the former with the telephone function, the latter is inconvenient to operate smoothly compared to the case without the telephone, and the latter in the case of installing the telephone handset on the keyboard. Even when working with a computer and talking on the phone at the same time, you must support the handset by using your neck and shoulders, so it is inconvenient to use it.You can make a phone call using the computer's built-in dialing program. When doing this, there were disadvantages such as stopping the existing computer work and dialing through the telephone.

Therefore, the present applicant has proposed Utility Model Registration Application No. 1999-1989 (keyboard phone), which includes a computer input circuit and a telephone circuit inside the keyboard,
