Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a text processing device for processing texts in a foreign language such as English, which consists of uppercase and lowercase letters.

0002

[Prior Art] Generally, English words are, for example, "I.L.O.
．． Abbreviations of international organizations such as ``SHARP'', company names such as ``SHARP'', headings with all capital letters such as ``REPORT'', ``June'', ``July'', etc.
”, which has a capital letter at the beginning and the rest are lowercase letters, such as “month”, “air”, “are”, “is”, etc.
There are three forms in which all letters are lowercase, such as a normal word such as ``.

[0003] Also, "June", "July", "a
Words such as ``ir,''``are,'' and ``is'' may also be capitalized when used as headings;
Even in normal words such as "" and "is," the first letter is capitalized and the rest are lowercase letters.

The conventional text processing device for processing the above-mentioned English words has character input keys for inputting alphabets, and mode keys for selecting uppercase input mode and lowercase input mode of the character input keys. If you have a keyboard with a built-in keyboard and want to enter a word that consists of all uppercase letters, a word that starts with a capital letter and the rest of the letters are lowercase, or a word that consists of all lowercase letters, Operator is the mode key
The size of the input character is selected by the input character and the character input keys are operated.

[0005] Other conventional text processing devices also have a spell check function or a corrector function, which allows them to detect words with a capital letter at the beginning and lowercase letters, or words with all lowercase letters like normal words. It is configured so that if you enter it incorrectly, it can be corrected automatically.

[0006]

[Problems to be Solved by the Invention] However, with the conventional text processing device described above, when inputting text in a foreign language such as English, the operator selects the size of the input characters, which is cumbersome to operate. If the input character size is incorrectly selected, there is a problem in that the character size must be corrected to uppercase or lowercase by key operation.

[0007] In addition, in conventional text processing devices having the above-mentioned spell check function or corrector function, when inputting in all capital letters such as a heading, it is not possible to automatically correct the input, and the operator has to use the keypad. Since corrections must be made manually, there is a problem in that the operations are troublesome.

SUMMARY OF THE INVENTION In view of the above-mentioned problems with conventional text processing devices, the present invention provides a text processing device that allows an operator to input foreign language text in characters of a desired size with simple operations.

[0009]

[Means for Solving the Problems] The present invention provides an input means capable of selectively inputting characters composed of uppercase and lowercase alphabetic characters, numbers, and special symbol characters, and a system in which all alphabetic characters are composed of uppercase characters. a first conversion means for converting into a word in which only the first letter of a letter is an uppercase letter and the rest are in lowercase; and a third conversion means for converting into a word in which all letters are formed from lowercase letters. Achieved by a text processing device that includes a conversion means and a control means that sequentially controls the first conversion means to the third conversion means so that a desired conversion means can be selected based on the state of characters input from the input means. be done.

0010

[Operation] According to the text processing device of the present invention, the input means selectively inputs characters composed of uppercase and lowercase alphabetic characters, numbers, and special symbol characters, and the first conversion means inputs all the alphabetic characters of the characters. Convert the word formed from uppercase letters and the second
The converting means converts the first character of each character into a word in which only the first letter is an uppercase letter and the rest are lowercase letters, the third converting means converts the first character into a word formed from all lowercase letters, and the control means converts the first character into a word formed from lowercase letters. The three conversion means are sequentially controlled to select a desired conversion means based on whether the characters input from the input means are uppercase or lowercase.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a text processing apparatus according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a flowchart showing the operation of an embodiment of the text processing apparatus of the present invention.

FIG. 2 is a diagram showing an example of the structure of a text processing device that operates according to the flowchart shown in FIG.

First, the text processing device shown in FIG. 2 will be explained.

The text processing device shown in FIG. 2 includes a keyboard 11,
It is composed of a control section 12, a program memory 13, a dictionary 14, a text memory 15, and a display section 16.

Next, each of the above constituent parts will be explained.

The keyboard 11 includes character input keys for selectively inputting alphanumeric characters and kana characters, and keys for selecting an alphanumeric input mode or a kana input mode of the character input keys. Mode key for selecting uppercase or lowercase character input mode of character input keys in numeric input mode, conversion key for converting input characters, and for confirming input characters and conversion characters It has various keys such as a confirmation key, a cursor key, and various function keys. The operation information for each key described above is processed by the control section 12.

When the alphanumeric input mode is selected by the mode key of the keyboard 11 and the character input keys are operated in sequence, each input character is stored in the sentence memory 1 in an undetermined state.
5 and displayed on the display unit 16. In the above-mentioned undetermined state, the spelling of the English word can be automatically corrected using the spelling data of the dictionary 14.

The program stored in the control unit 12 is stored in the program memory 13 in advance. The program memory 13 is, for example, a read-only memory (ROM).
).

The dictionary 14 stores in advance data for kana-kanji conversion or spelling data of English words. Note that the data for kana-kanji conversion and spelling data may be composed of a general dictionary and a user dictionary.

The control unit 12 controls the keyboard 1 based on the program stored in the program memory 13 in advance.
1, the kana characters input through the dictionary 14 can be converted into kanji using the data for kana-kanji conversion in the dictionary 14, and the spelling of English words can be corrected using the spelling data in the dictionary 14.
Reference) allows you to control the size of each letter in English sentences and words.

[0022] The text memory 15 is composed of, for example, a random access memory (RAM), and has a work area for the control unit 12 to edit and store texts in Japanese or foreign languages as described above. .

The display section 16 is constituted by a cathode ray tube (CRT) or a liquid crystal display, and is controlled by the control section 12 to display text being edited, a cursor, and the like.

Next, the operation of the text processing apparatus shown in FIG. 2, particularly the operation of the control section 12, will be explained with reference to FIG.

First, when the conversion key on the keyboard 11 is operated (step S1), it is determined whether or not there is an undefined area in the input character (step S2).

If there is an undefined area in step S2, it is determined whether the word in the undefined area consists only of alphanumeric characters and special symbols (step S3).

On the other hand, if there is no undefined area in step S2, the word where the cursor is located or the one at the cursor position
The previous word is determined as the conversion word (step S5), and it is determined whether the conversion word consists only of alphanumeric characters and special symbols (
Step S6) If YES in step S5, the process proceeds to step S7, which will be described later.

If YES in the above step S3, it is determined whether or not candidate words for the words in the undefined area still exist in the dictionary 14 (step S4), and if N is determined in the above step S3.
In the case of O, separate processing is performed.

If YES in step S4, the process advances to step S7, which will be described later.

[0030] In step S7, the process of converting the first character of a sentence or conversion word in an undefined area in which all characters are capital letters to uppercase letters and converting the remaining characters to lowercase letters (step S9 to be described later); A process of converting all the characters of the text or converted word in the undefined area in which the remaining characters are lowercase letters into lower case (step S11 described later), Either one of the processes for converting to uppercase letters (step S13 described below) is not performed, or S9, S1
1. It is determined whether or not the necessary processing has been performed in the processing of S13, and if YES, the process proceeds to step S8.

Note that the order of the processes shown in steps S3 and S4 may be reversed.

[0032] If NO in the above step S7, another process is performed.

Next, it is determined whether all the characters of the sentence or converted word in the current undefined area are capital letters (step S8), and if YES in step S8, the first letter of each word is capitalized. The remaining characters are converted to lower case letters (step S9), and the process proceeds to step S14, which will be described later.

If NO in step S8, it is determined whether the first character of the sentence or converted word in the current undefined area is an uppercase letter and the remaining characters are lowercase letters (step S10); If YES in step S10 above, convert all characters to lower case (step S1
1), proceed to step S14, which will be described later.

Furthermore, if NO in step S10, it is determined whether all the characters of the sentence or converted word in the current undefined area are lower case (step S12), and if YES in step S12, Convert all characters to uppercase (step S13) and proceed to step S14, which will be described later.
Proceed to.

In step S14, the characters are displayed on the display section 16 in the converted size. If the conversion key is operated again in this state, the process returns from step S15 to step S7.

In step S9, instead, it is determined whether the word is registered in the dictionary 14 by converting it to all lowercase letters, and if it is registered, the word is set to all lowercase letters and the word is not registered. If not, the first letter of each word may be capitalized and the remaining letters converted to lowercase.

Next, the above process will be specifically explained based on example sentences.

For example, “THERE IS A PEN.
When the conversion key is operated when a sentence in which all letters are written in capital letters is in an undefined state, such as "There Is A P
en. '', only the first letter of each word is emphasized with an uppercase letter, and the rest are all lowercase letters.

[0040]Also, ``There Is A Pen.''
When the conversion key is operated when a sentence in which only the first letter of each word is emphasized with a capital letter and the rest are all lowercase letters is in an unconfirmed state, such as ``there is The text is converted into a sentence in which all characters are lowercase, such as ``a pen.''.

Furthermore, "there is a pen."
If the conversion key is operated when the text is in an unconfirmed state, such as "THERE ISA PEN.," when the conversion key is operated, the text is changed to a format in which all characters are uppercase, such as "THERE ISA PEN." is converted into a sentence.

[0042] Although this embodiment is configured to convert into three formats, for example, "There is a
pen. ”, that is, when a sentence in which only the first letter of the first word is capitalized and the rest are all lowercase letters is in an undefined state, such as a normal sentence, “THERE
IS A PEN. '', in which all characters are capitalized, and the text may be converted into four formats.

[0043] Also, the sentence “There is a PE
N. ” is confirmed, the cursor moves to the word “P
EN” or on any of the characters in the
If the conversion key is operated when the sol is located one place after the word "PEN", only the first letter of the word will be highlighted with a capital letter and the rest will be changed to the word "Pen" with all lowercase letters.
You may also convert it to .

Similarly, the word "Pen" may be converted to the word "pen" in all lower case letters, and the word "pen" may be converted to the word "PEN" in all capital letters.

As described above, according to the above embodiment,
When the conversion key on the keyboard 11 is operated, the control unit 12
is easy to operate because it converts sentences and words with all uppercase letters, sentences and words where only the first letter is uppercase and the rest are lowercase letters, and sentences and words where all letters are lowercase letters depending on the current state. This allows the operator to input foreign language text in the desired size.
