Abstract

PURPOSE:To improve the data input efficiency as well as the working efficiency of a data input device by providing a conversion input part to a data input part to convert a certain character string into another one. CONSTITUTION:A data input device consists of a central processing unit CPU1, a main storage 2, a display device CRT3 and a data input part 4. The input data given from the part 4 and the processing result of the CPU1 are displayed on the CRT3. Here a conversion input part 4a is added to the part 4 to convert a certain character string into another one. Furthermore a character string conversion instruction is defined to an optional key at the part 4 to convert KANA (Japanese syllabary) into the English capital letters, numeric characters, etc. Then a character string supplied mistakenly is recognized together with a character string supplied mistakenly is recognized together with a character string whose input is actually desired. Then a key designated for conversion is pushed and therefore the CPU1 performs the conversion in response to an instruction to display the result of conversion on the CRT3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input device, and particularly to character string conversion of input data.

[Conventional technology]

A conventional data input device is shown in FIG. In FIG. 5, 1 is a central processing unit (hereinafter referred to as rcPUJ), 2 is a main storage unit memory (hereinafter simply referred to as "memory"), 3 is a display device (hereinafter referred to as rCRTJ), 4 is a data input unit, and 5 is a display device (hereinafter referred to as rCRTJ).
is a signal line.

Next, the functions of each component constituting this device will be explained. The CPUI controls the entire data input device and executes command processing. Memory 2 stores input data and processed data. The CRT 3 displays input data and processing results from the data input section 4. Data input section 4
has a mode key for inputting data and switching input of characters such as English and kana.

Data input from the data input section 4 is converted into an electrical signal and transmitted to the CPUI via a signal line 5.

FIG. 6 is a flowchart showing the processing flow of the conventional data input device when data is input from the data input section 4.

Next, the operation of this data input device will be explained. Fifth
In the figure, when there is data input from the data input section 4, the CPU 1 performs the following steps as shown in step 11 of FIG.
Through the data input routine, data is temporarily stored in the memory 2 and displayed on the CRT 3. The CPUI continues to store this character string in the memory 2 until input data indicating that the input character string has ended is input from the data input section 4. When the CPUI detects input data indicating that the input character string has ended, if it determines that the input character string is a command (instruction) to start a program in step 12 shown in FIG. 1
In step 3.14, the instruction is interpreted, processing is executed according to the instruction, and the result is displayed on the CRT 3.

When inputting data from the data input section 4, the CAPS key of the mode key is turned on when the character string is in uppercase letters, and the Kana key of the mode key is turned on when the character string is in kana.

[Problem that the invention seeks to solve]

However, with conventional data input devices, if data is entered while the mode key is turned on or off incorrectly,
There was a problem in that when an incorrect input was noticed, the user had to correct the on/off status and re-enter the data.

The present invention has been made in view of the above points, and its purpose is to perform conversion processing from a character string input by mistake using the CAPS key or Kana key to a character string that should actually be input. The object of the present invention is to provide a data input device that can perform the following functions.

[Means for solving problems]

In order to achieve such an object, the present invention is such that the data input section is provided with a conversion input section for converting a certain character string into a different character string.

[Effect]

In the present invention, character string conversion processing is performed by providing a conversion command to a conversion input unit.

〔Example〕

An embodiment of the data input device according to the present invention is shown in FIG. The input section 4 is configured.

In FIG. 1, the same or equivalent parts as in FIG. 5 are given the same reference numerals. In the data input unit 4 that constitutes this data input device, from kana to uppercase letters/numbers, from kana to lowercase letters/numbers, from uppercase letters/numbers to kana, from uppercase letters to lowercase letters, from lowercase letters/numbers to kana, then lowercase letters. A string conversion instruction from to uppercase letters is defined for any key.

Next, the operation of the device having such a configuration will be explained in Figs. 1 to 4.
This will be explained using figures. FIG. 2 is a flowchart for explaining the operation of this data input device, FIG. 3 is a flowchart of the conversion routine shown in FIG. 2, and FIG. 4 is an example of the configuration of a conversion table. As shown in FIG. 2, after inputting data by the data input routine shown in step 21,
In step 22, it is determined whether the operator entered the mode key incorrectly when inputting data. If an incorrect input is made there, the process branches to the conversion routine shown in step 26.

Next, the processing in the conversion routine will be explained using FIG. 3. First, the operator determines whether the transformation is a one-row transformation, and if it is not a one-row transformation, step 4
1 to specify the range and proceed to step 32. Next, in steps 32 to 36, the erroneously input character string and the character string actually desired to be input are recognized, and a key designated for the conversion is pressed. The CPUI that received the conversion command performs steps 42-
As shown in 47, the conversion process is performed according to the command, and CR
Display on T3.

FIG. 4 shows a conversion table. In FIG. 4, 50 indicates a block of uppercase letters and numbers, 60 a block of lowercase letters and numbers, 70 indicates a kana block, 51 to 54 indicate uppercase letters, 61 to 64 lowercase letters, and 71 to 74 indicate katakana. The conversion process described above is performed according to such a conversion table. For example, suppose that the kana key is turned on by mistake when the user wants to execute the command rD I RJ. Then, the CRT 3 will display katakana, for example, "Shinisu". Therefore, among the keys that have character string conversion commands, if you press the key that has the command to convert from kana to uppercase letters and numbers, "shi" is the fourth katakana 74 in the kana block 70, so block 50
The fourth letter rDJ, which is the capital letter 54, is selected and converted. Similar processing is performed for "2" and "su", and C
In RT3, rD I RJ is displayed instead of "Sinis".

In this embodiment, the conversion of commands has been explained, but the conversion is not limited to cases where the CAPS key or Kana key is operated incorrectly, and conversion may be performed by specifying a range on the program or text. , in this case, the same effects as in this embodiment are achieved.

〔Effect of the invention〕

As explained above, the present invention enables conversion from a certain character string to a different character string by providing a conversion input section for converting a certain character string to a different character string in the data input section. There is no need to re-enter data if the mode key is turned on by mistake, making data entry more efficient.
It has the effect of improving work efficiency.
