Description

A keyboard having a telephone}

TECHNICAL FIELD The present invention relates to a keyboard, and more particularly, to a telephone combined keyboard that enables a telephone call to be made and received independently of the computer by sharing the numeric keypad of the computer with the telephone button.

In general, computers and telephones are essential office tools in an office environment. These phones and computers are usually used on a desk, the desk is limited in size in the office, there is a problem that it is inconvenient to make or receive calls while working on the office. That is, if the telephone is placed away from the computer, if the telephone is placed while the computer is performing, the copper wire becomes long, which causes inconvenience. This is true even if you are trying to answer an incoming call.

Therefore, there has been a demand for a device capable of making and receiving phone calls while working with a computer while maximizing a narrow space.

SUMMARY OF THE INVENTION An object of the present invention is to provide a telephone-compatible keyboard which allows for making and receiving calls independently of the computer by sharing the numeric keypad of the computer with the telephone buttons in order to meet the above requirements.

1 is a block diagram of a dual-use keyboard according to a preferred embodiment of the present invention.

FIG. 2 is an internal circuit diagram of the keyboard shown in FIG. 1.

In order to achieve the above object, the numeric keypad; Telephone line ports for inserting telephone line jacks from telephone terminals; A handset port for inserting a handset jack from the handset; A switching switch for switching between a first switching state in which a numeric command input through the numeric keypad is input into a computer main body, and a second switching state in which the command is input into a telephone terminal; And a telephone board for performing a call and answer function by correspondingly connecting terminals corresponding to each numeric key of the numeric keypad and terminals of a telephone button to each other, and wherein the changeover switch is in a second switching state. And dialing by inputting a numeric key to the numeric keypad, and receiving the incoming call through the handset regardless of whether the changeover switch is in a first switching state or a second switching state. A combined keyboard is provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a dual-use keyboard according to a preferred embodiment of the present invention.

The telephone combination keyboard 10 shown in FIG. 1 includes a keyboard portion 12, a numeric keypad portion 14, a handset port 16, a handset 18, a changeover switch 20, a phone port 22, a keyboard port. (24).

In FIG. 1, a keyboard unit 12 for inputting numbers, alphabets and other function keys, a numeric keypad unit 14 for inputting numeric keys 0-9, and a computer body (not shown) are connected to a keyboard. The keyboard port 24 is identical in function and form to that of a general keyboard.

Meanwhile, the handset port 16, the handset 18, the changeover switch 20, and the telephone port 22 are parts that are not present in the general keyboard, and their functions are as follows.

The telephone port 22 is a port for inserting a telephone line jack from a telephone terminal. The handset port 16 is a port for inserting a handset jack from the handset 18.

The changeover switch 20 functions to switch between a first switching state in which a numeric command input to the numeric keypad 14 is input to the computer main body, and a second switching state in which the command is input to the telephone terminal. . That is, the same numeric keypad 14 operates as part of a computer input device in the first switching state, and performs the function of a telephone button in the second switching state.

The phone board (not shown) is an essential part of a phone that performs various processes necessary for making and receiving calls, and is embedded in the keyboard 10 so that the terminals of the telephone buttons and the terminals corresponding to the respective numeric keys of the numeric keypad 14 are provided. Make sure the terminals are connected with the same number. In general, except for the part occupied by the number and the special symbol button, the phone is very small and simple, so that the phone board can be easily incorporated into the keyboard by those skilled in the art. This will be described in more detail with reference to FIG. 2, which is an internal circuit diagram of the keyboard 10 of FIG. 1. In FIG. 2, reference numeral 30 denotes a part of an internal circuit diagram of the keyboard.

In general, both keyboards and phones use a combination of wires to identify which button was pressed. Accordingly, the numeric keypad 14 and the terminals of the numeric keypad and the telephone board so that the numeric keys act as a telephone, it may be connected to each other.

It should be noted, however, that the arrangement of the number keys connected to each terminal increases in the number from the bottom to the top in the case of the keyboard, while the phone increases the number from the top to the bottom. Therefore, when connecting the numeric keypad 14 and each terminal of the telephone board, do not simply map 1: 1 the same position to 1: 1, and analyze the circuit diagram of each board well and dial the number 0 on the keyboard. The buttons should be connected so that the numbers match, for example, by connecting button 0 to the number 5 button.

Referring now to FIG. 2, the keyboard terminals 1,2,3 and 4,5,6, ... are connected to 1,2,3, and 4,5,6, ..., etc. of the telephone board. Able to know. Of course, the terminals on the keyboard logic board are also connected to the numbered keyboard terminals. The numeric keys input from the numeric keypad 14 of the keyboard 10 may be selectively input to the keyboard logic board through the changeover switch 20 or may be input to the telephone board. In other words, when the input of the numeric keypad 14 is input to the keyboard logic board in one switching state, it will perform some of the general computer tasks. You will be dialed.

When receiving an incoming call from the outside, the incoming call can be received through the handset 18 regardless of the switching state of the switch 20. This is because, in an incoming call, a voice signal is input from the telephone terminal to the telephone port 22 and is heard through the handset 18 through the processing of the internal telephone board, so that it operates independently of the numeric keypad 14. That is, the telephone board is selectively connected to the keyboard terminal on the one hand and to the telephone terminal on the other hand.

On the other hand, if the receiver 18 is made of a microphone combined with a microphone and earphone, there is no need to provide a handset separately, it can reduce the volume much.

The present invention is not limited to the above-described embodiments, and of course, modifications can be made by those skilled in the art without departing from the spirit of the present invention. Therefore, the scope of the claims in the present invention will be limited to the claims below, not the scope of the detailed description.

According to the present invention, it is possible to reduce the space occupied by a telephone which is usually placed near a keyboard in a general office or home desk, and even when not using a computer or through a modem, only the operation of a switch and the number of numeric keypads are used. You can make a call with just a keystroke. In addition, when making the handset in the form of a microphone, not only the design is clean, but also there is an advantage that can make a telephone call without inconvenience while watching office work.
