Abstract

PURPOSE:To omit the use of memo paper and electronic calculators by adding a calculation function to the ten-key part to secure the function of an electronic calculator through switching actions and also using a display panel for the result of calculation and an execution key for input of the result of calculation. CONSTITUTION:If it is required to supply the numerical value requiring the calculation while a document is edited, a changeover switch 9 is operated to secure connection among a ten-key part 2, a calculation circuit 8 and a display device 10. Then the circuit 8 carries out the calculation via the part 2 and the result of this calculation is displayed on the device 10. Then the numerical value of the device 10 is supplied to a word processor main body 1 with push of an execution key 11 of a keyboard device 3. Then the switch 9 is operated again to secure an ordinary function again and the device 3 is operated. Thus the result of calculation is displayed on a document picture under editing.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a keyboard device connected to a word processor, a personal computer, or the like.

(Prior Art) Conventional keyboard devices of this type have been used to input information into word processors or personal computers connected thereto.

(Problem to be Solved by the Invention) However, with the above configuration, if you want to manually calculate numerical values after performing simple arithmetic calculations while using a word processor or personal computer, you can do the calculations using memo paper. There was a problem in that it was necessary to carry out calculations using a prepared calculator, and it was necessary to have memo paper and a calculator on hand.

The present invention solves the above problems and provides a keyboard device that does not require memo paper or a calculator.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a calculation function to the numeric keypad part of the keyboard, allows it to operate as a calculator by switching, and displays the calculation results. The keyboard is provided with a display board and an execution key for inputting the above calculation results into a connected word processor or personal computer.

(Function) With the above configuration, even if it is necessary to perform four arithmetic calculations while inputting data on the keyboard device, the numeric keypad can be switched to the calculation function and the calculation results can be calculated. After visually checking the
For example, you can manually edit the document editing screen.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 and 2, taking as an example a case where the invention is connected to a word processor.

FIG. 1 is a block diagram of a word processor device, in which a word processor body 1 is provided with a keyboard device 3, which is equipped with a numeric keypad portion 2 as shown in FIG. 4. A display device on which input information is displayed. Connected are a floppy disk device 5 and a hard disk device 6 for storing input information, and a printer 7 for outputting created documents and the like.

The keyboard device 3 has a built-in calculation circuit 8, and a changeover switch 9.degree. display device 10 and an execution key 11 are arranged on the keyboard.

The operation of the word processor device configured in this way will be explained.

When editing a document, if it becomes necessary to enter numerical values that require calculation, operate the changeover switch 9 and press the numeric keypad 2.
, the calculation circuit 8 and the display device 10 are connected. Next, when calculation is performed using the numeric keypad section 2, the calculation is executed by the calculation circuit 8, and the result is displayed on the display device 10.

Next, when you press the execution key 11 on the keyboard device l\3,
The numerical values on the display device 10 are input into the word processor main body 1. Next, by operating the changeover switch 9 again to return to the normal function, and then operating the keyboard device 3, the above result will be displayed on the screen of the document being edited.

(Effects of the Invention) As explained above, according to the present invention, even if it is necessary to manually enter numerical values that require calculation while using a word processor or personal computer, by operating the changeover switch of the keyboard device, the electronic Calculations can be performed as a computer, and the calculation results can also be performed manually by operating the execution key, eliminating the need for manual calculations or manual work, and providing an easy-to-work keyboard device.

Additionally, there is no need to provide accessories such as memo paper and calculators, which were required in the past, resulting in a simpler workspace.
