Abstract

PURPOSE:To attain the function of a touch keyboard with use of an alphanumeric keyboard by providing a key code processing part which includes a mode table storing the set contents of a mode changeover switch, and discriminates and processes the key input contents. CONSTITUTION:A keyboard 1 of a JIS array is provided with a mode changeover switch 2 and connected to a key code processing part 3 which decides the key input contents. The part 3 includes a mode table which stores the set contents of the switch 2 and reads a character string corresponding to the received key information out of a keyboard table file 5 which stores the correspondence between the keys and the character strings. Then the part 3 outputs the received data to a data processing part 6 which processes the data as the display data. Thus the items can be inputted through an alphanumeric keyboard.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard input device, and particularly to a keyboard input device having an item input mode. .

[Conventional technology]

Various types of conventional keyboard input devices have been put into practical use, but for example, in workstations that perform OA processing, there is a need to input items with fewer key inputs by using one-touch input devices. You can use the touch keyboard. This touch keyboard is the fifth
As shown in the plan view of the figure, the keys are arranged in a matrix, and when any key is pressed, the character string corresponding to the input key is output according to the contents of a predetermined touch keyboard file. Ink.

Note that this touch keyboard is configured so that normal character-by-character input is also possible by switching to alphanumeric mode.

[Problem to be solved by the invention]

The conventional touch keyboard mentioned above is suitable for inputting items because it can be entered using the ``wanta'' and ``y'' keys, but the key layout is different from a normal alphanumeric keyboard, so it is suitable for documents that require alphanumeric input. There is a problem that it is not suitable for input, etc.

Therefore, the keyboard of the multifunctional work station Shiron, which is used for a variety of tasks, does not have a touch keyboard.

An object of the present invention is to provide a keyboard input device that combines the functions of a touch keyboard with a normal alphanumeric keyboard.

[Means to solve the problem]

The keyboard input device of the present invention includes an alphanumeric keyboard having a mode changeover switch that switches between an alphanumeric input mode and an item input mode, a keyboard table file that stores correspondence between keys and character strings, and settings for the mode changeover switch. By comprising a key code processing section that includes a mode table that stores contents and processes the content of key inputs, a data processing section that processes data received from the key code processing section as display data, and a display section. When an item input is selected with the mode changeover switch, the key code processing section reads a character string corresponding to the key information received from the keyboard from the keyboard table file and inputs the item with the alphanumeric keyboard.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

A keyboard 1 having a JIS layout is provided with a mode changeover switch 2, and is connected to a key code processing section 3 that processes the content of key inputs. The key code processing section 3 is
It is equipped with a mode table 4 that stores the settings of the mode changeover switch 2, reads character strings corresponding to the received key information from a keyboard table file 5 that stores the correspondence between keys and character strings, and displays the received data as display data. The data is output to the data processing section 6, which processes the data as follows. The data processing unit 6 transfers the processed display data to the display device 7.
Enter and display.

FIG. 2 is a storage pattern diagram showing the storage contents of the keyboard table file.

The keyboard table file stores character strings 22 corresponding to key information 21.

Next, the operation will be explained.

First, the display pattern will be explained assuming that data is input into the tabulation list shown in FIG. Also, in this example, if you enter data in the "unit price" and "quantity" columns, "
It shall have a function to calculate and display the data in the "Amount" column. FIG. 4 shows the display pattern after input. In the explanation, FIGS. 1, 2, 3, and 4 will be used as appropriate.

When the operator selects the item input mode with the mode changeover switch 2 of the keyboard 1, the key code processing section 3 sets the mode table 4 to the item input mode. If mode table 4 is in item input mode, press “A” on keyboard 1.
When the key is pressed and the code "A" is notified to the key code processing section 3, the key code processing section 3 searches the keyboard table file 5 and returns the character string "zoo" associated with "A". Read tΔ△△△500.The key code processing unit 3 reads the read character string “Zoo 1△△△△5
00'' to the data processing unit 6, and the data processing unit 6 writes the character string “Z001△△△△500” on the screen of the display device 7 in the same way as if it were input one character at a time. The input of "Product code" and "Unit price" items is completed.

Next, when the operator selects the alphanumeric mode with the mode changeover switch 2, the key code processing section 3 that receives this information changes the settings of the mode table 4. When the mode table 4 is alphanumeric mode, the key code processing unit 3
The characters of the code notified from are passed to the data processing unit 6 character by character. If you enter "10" in "Quantity", the amount will be automatically calculated and the screen will appear as shown in Figure 4.

Of course, if mode table 4 is in alphanumeric mode, press “A” on keyboard 1.
”, the display device 5 displays one character “A”.

〔Effect of the invention〕

As explained above, the present invention provides an alphanumeric keyboard having a mode changeover switch that switches between an alphanumeric input mode and an item input mode, a keyboard table file that stores the correspondence between keys and character strings, and settings for the mode changeover switch. By comprising a key code processing unit that includes a mode table that stores the content and processes the content of key inputs, a data processing unit that processes data received from the key code processing unit as display data, and a display unit. The effect is that you can use touch keyboard functions with a normal alphanumeric keyboard.
