Abstract

PURPOSE:To improve the data input efficiency and then the operability in an input/output control system by changing the code information received once into the other code information in an optional shift state over an optional range. CONSTITUTION:An operator pushes a shift change key 31 when he/she knows a wrong shift operation of a keyboard 3. A main processor 1 stores at first the keyboard shift state information of that time point into a register 41 and moves a cursor to designate a range of the wrong input. Then a shift code showing an alphameric shift mode is stored in a register 42 with push of an alphameric shift key. Then a code of 'CHI' (KANA (Japanese syllabary)) corresponding to the present cursor position is taken out of the input code data stored in a display refresh memory 61 and a code of 'A' is acquired by reference to a table 5. The code of 'A' is stored in the memory 61 and the cursor is advanced by one step. Hereafter the same actions are successively repeated to secure the input of a desired key. Thus the operability is improved in an input/output control system in case a wrong shift operation is carried out for the keyboard.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a key input mechanism in which a plurality of characters written on a key top can be selectively input by switching the shift state. The present invention relates to an input/output control method having a function of changing code information once input into code information in any other shift state over an arbitrary range.

(Prior art) When inputting data into a field or line using a keyboard (KB) using a display screen, for example, alphanumeric/kana/alphabetic symbols/kana characters are input in order to automatically shift the keyboard to the field. A data type such as symbol/hiragana/kanji (full-width) is specified, and a keyboard shift is set when the cursor moves into the field.

This allows automatic keyboard shift settings to be performed by various means not only for field input, but also for line input, single key input, etc., and greatly contributes to improved operability.

However, this type of control is only suitable for the input situations in which the shift is most appropriate.
It is determined based on certain standards and may not necessarily match the input situation of the operator.

In such a case, it is necessary to press the shift key to change to another shift, but it often happens that the user forgets to press the shift key and inputs data.

To correct such a scene, there is a drawback in that the data part that has been previously entered by key must be re-entered.

(Problems to be Solved by the Invention) As described above, in the past, if you forget to press the shift key and enter a key, you have to re-enter the data part that you entered even if the shift is simply different. There were problems in terms of operability.

The present invention has been made in view of the above-mentioned circumstances, and even if you forget to operate the shift key and input data, the input data is not re-inputted, but can be transferred to any specified range under any other shift state. The purpose of the present invention is to provide an input control method that can be converted into a code, thereby increasing data input efficiency and improving operability.

[Structure of the Invention] (Means and Effects for Solving the Problems) The present invention provides a key input mechanism in which a plurality of characters written on a key top can be selectively input by switching the shift state. A keyboard equipped with a specific function key that prompts the conversion of the code of the ζ 11th data that has been completed into a code of another shift state, and when a specific function key on the keyboard is pressed, means for storing the shift state of the keyboard (first shift state B); means for specifying the range of application of the function of the specific function key by a cursor back key; '14 U shift state (second
Shift-like 7! means for storing the inputted data in the range specified by the cursor back key into key position information according to the first shift state; 2, and a means for converting the code information into a code according to the shift state described in FIG. , even if you forget to use the shift key and enter data, you can convert the input data to a code under any other shift state over any specified range without having to re-enter it, increasing data input efficiency and improving operability. can do.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

Here, the key position is shown in the vertical direction and the keyboard shift is shown in the horizontal direction, and a code corresponding to the key position and keyboard shift is generated. Note that this key code conversion table (TBL) 5 includes other control information in addition to the code, and is not essential to the present invention, so a description thereof will be omitted here.

FIG. 3 is a diagram showing an example of a character layout corresponding to each shift in the key tops on the keyboard.

Figure 4 is for explaining the operation in the above embodiment.Here, I wanted to input "key ABCDE", but I forgot to change the shift to alphanumeric shift and entered the key. An example is shown.

FIG. 5 shows the result of performing the shift conversion operation in the above embodiment. °
This shows the state in which each character is converted to an alphabetic character on the same key top in alphanumeric shift mode.

FIG. 7 is a flowchart for explaining the operation in the above embodiment.

The operation of one embodiment of the present invention will now be described with reference to FIGS. 1 to 7.

The key tops on the keyboard 3 are keys 32. as shown in FIG.
33.34. . . , 38 in this order, the main processor 1 searches the key code conversion table 5 having the key position contents shown in FIG. Then, the following chords are obtained in sequence: ``chi, ko, so, shi, i''.

These key input code data are stored in the display refresh memory 61 under the control of the main processor 1, and are further displayed on the display unit 8 under the control of the display controller 7 (step S in FIG. 7).
L, 5ll). An example of this display is shown in FIG.

At this time, dependent information indicating whether the input data is full-width or half-width is stored in the attribute refresh memory 6.
2.

Here, the operator should originally
, C, D, E”, but when I realized that I made a mistake in the shift operation on the keyboard 3, I changed the keyboard 3.
Press the upper shift conversion key 31.

When the main processor 1 detects the pressing of the shift conversion key 31, it first outputs the keyboard shift state information (
shift code) is stored in the register 41 (steps St and S2 in FIG. 7).

In this example, when the shift conversion key 31 is pressed, the keyboard shift state is the kana shift mode, so a shift code indicating the kana shift mode is stored in the register 41.

Next, in order to specify the area where the input was incorrect, use the cursor back key [-] (left cursor key) to move the cursor to the character position of "chi".

At this time, a feature of cursor back key processing is that when the most recently operated key is not a cursor back key,
Store position information of [current cursor position -1] in register 9. Therefore, if the cursor back key is pressed continuously, the register 9 is not updated (steps 83 to S5 in FIG. 7).

Thereafter, when the alphanumeric shift key is pressed, a shift code indicating the same shift state, that is, alphanumeric shift mode, is stored in the register 42 (step S7 in FIG. 7).

Then, from the input code data stored in the display refresh memory B1, the code corresponding to the current cursor position is extracted, and it is determined that the previously stored shift state information in the register 41 is a kana shift code. The key position corresponding to the code position of "CH" is obtained by searching the area corresponding to the kana shift in table 5 whose contents are shown in FIG. 2 (step S7 in FIG. 7).

Next, from this key position, it is recognized that the shift state stored in the register 42 is an alphanumeric shift, and by referring to the table 5, the code of 0 is entered into "i', ?".

This code ("A") is stored in the display refresh memory 61 and the cursor is moved forward by one (steps 88-510 in FIG. 7).

Next, repeat the same operation as above for "C, So, C, I" in order, and obtain "B, C, D, E" respectively.
” and stores the same code in the display refresh memory 61 (steps 87 to 510 in FIG. 7).
.

As a result, the desired key input as shown in FIG. 5 has been achieved.

By having the above-mentioned shift conversion function, if there is an error in the keyboard shift operation, it can be repaired with a simple operation, whereas in the past, you had to redo the shift operation and re-enter the input. This significantly improves operability.

[Effects of the Invention] As detailed above, according to the human output control method of the present invention,
In a key input mechanism in which multiple characters written on the key top can be selectively input by switching the shift state, the code of the input data under the first shift state can be input into another second state. a specific function key that prompts the code to be converted into a code in the shift state; and a means for holding the first shift state at that point in time when the specific function key is pressed; Other second data from the
means for specifying a range of the input data to be converted into codes of the shift state; means for specifying the second shift state; and means for specifying each code of the input data specified in the range according to the first shift state. means for converting into key position information; and means for converting the converted key position information into a code according to the second shift state; By having a configuration that has a function that allows you to change the code information depending on the state, even if you forget to press the shift key and input data, the input data can be changed over any specified range without re-entering the input data under any other shift state. It can be converted into a code, increasing data entry efficiency and improving operability.
