Keyboard Combined Phone {Keyboard Combined With Telephone}

The present invention is to reduce the office space by adding a telephone function to the computer keyboard in the phone and the computer keyboard required in the office, and to improve the office automation function and to collect the above office supplies in one place, the user is convenient to use.

And when you want to make a phone call using the Internet, you can use it without any additional equipment, and you can make a phone call while the computer is turned off.

In general, the office occupies a lot of office space (desk area) because telephones, computers, and electronic calculators are placed separately.

And office work is mostly computer and telephone liaison, with both phones and keyboards almost always co-located.

Desks with telephones and computer keyboards clutter up the office environment, which undermines the ability of office automation (OA), and is not aesthetically pleasing, but it is not a good idea to buy both phones and keyboards. It is unreasonable financially to do.

Therefore, there is a practical problem that computer keyboards, telephones, and electronic calculators are all indispensable in office desks.

The number plate on the right side of the computer keyboard can be used as a phone number plate to achieve the purpose of reducing office space and improving office automation by adding phone functions to the computer keyboard by combining the necessary phone and computer keyboard in the office. Add a cut-off switch and use it as a computer keyboard when making a phone call, and use the switch to cut the phone number so that the phone number can be displayed by attaching a liquid crystal display.

In addition, for computer users who are not good at computers such as spreadsheets (EXCEL, etc.), an electronic calculator function can be added to the above computer keyboard to make calculations easier if a simple calculation is required while creating an account book or document. It is a feature of the present invention to further improve the problems of the prior art by additionally installing a switch for attaching an electronic calculator cut switch to a computer keyboard so that the number plate on the right side of the computer can be used as a calculator button.

Hereinafter, described in detail by the accompanying drawings as follows.

Fig. 2 shows a device for inserting an electromagnetic plate for a general telephone which can function as a telephone in a general computer keyboard (Fig. 1), a telephone cut-off switch 2, a speaker 6, a telephone receiver contact terminal (jack) 5, It is a keyboard equipped with a liquid crystal display (1) and is usually used as a computer keyboard.

When you want to make a call, press the telephone cut-off switch (2) so that the function of the number plate (4) on the right side of the computer can be switched (cut off) from the keyboard role to the telephone number dial button.

In addition, pressing the switch (2) again after the end of the call allows the right numeric keypad (4) to switch back to the computer keyboard.

In addition, the LCD screen 1 is additionally installed on the keyboard as a device to display a telephone number to be pressed when making a call so as not to make a mistake.

And since the telephone hook switch 2 performs the on-hook switch function, the telephone receiver connected to the telephone receiver contact terminal (jack) 5 can be used by simply hanging it on the computer monitor or the main body.

When inserting a general electronic calculator electronic board that can function as an electronic calculator into the keyboard, and attaching the electronic calculator cut-out switch (3) and the LCD screen (1), it is usually used as a computer keyboard. If you need a simple calculation function while using a computer for writing or household accounting, use the electronic calculator cutout switch (3) to convert the right number plate (4) to the calculator number plate (8) and the LCD screen (1) It is used as a liquid crystal display (calculation window) 7 and when the calculation is finished, it is again possible to press the electronic calculator cut switch so that the numeric keypad 4 can be switched with a computer keyboard.

FIG. 3 is an enlarged view of the computer keyboard right side of FIG. 2 when only a telephone function is added, and FIG. 4 shows an enlarged view when an electronic calculator function is added.

FIG. 6 is a diagram illustrating the operation of the cut-out switch. When the numeric keypad button on the right side of the keyboard is pressed, the switch converts (cuts) this signal to one of a telephone board (or a calculator board) and a keyboard board.

And Figure 7 shows that the telephone line (telephone to telephone terminal connection line) and the cable connection line (keyboard and computer main body connection line) as the keyboard connection line (keyboard and computer main body connection line) to separate the telephone line and keyboard connection at the end after being coated will be.

In addition, if the telephone receiver contact terminal (jack) 5 is placed behind the main body of the computer using the keyboard connection line, the telephone receiver cable may not be visible around the keyboard. You can also use it as an Internet phone (e.g. dial pad).

As described above, the present invention allows the computer keyboard to function as both a telephone function and an electronic calculator, and a cutout switch is attached so that the number plate on the right side of the computer keyboard can be used as a phone number plate. In order to use it as a telephone number button, a function of cutting by using a switch is added, and an LCD screen is attached so that the telephone number is displayed.

It is also a feature of the invention that the call can be made while the computer is off.

In addition, for computer users who are not good at computers such as spreadsheets (EXCEL, etc.), an electronic calculator function can be added to the above computer keyboard to make calculations easier if a simple calculation is required while creating an account book or document. In order to improve the office environment and the user's convenience, an additional switch is attached to the computer keyboard so that the number plate on the right side of the computer can be used as a button for a calculator.

In addition, if the telephone line (telephone to telephone terminal) is bundled together with a keyboard cable (keyboard and computer main body cable), the telephone line can be neatly arranged.

In addition, when using a wireless handset (telephone), there is no telephone line, so you can access a more convenient office environment.
