Description

[0001]
[Industrial application fields]
The present invention relates to a character conversion device that converts a character into another character in a word processor or the like.
[0002]
[Prior art]
In a word processor or the like, various numerical characters having a size corresponding to one character can be used in order to easily show items.
[0003]
For example, in the document example shown in FIG. 5A, a circled number is used as a numerical character, and in the document example in FIG. 5B, parenthesized numbers are used. In addition, Roman numerals (uppercase letters and lowercase letters) are often used as numerical characters, as shown in FIG.
[0004]
By the way, in a document using such numerical characters, there are cases where it is desired to change the type of numerical characters used. In such a case, for example, when it is desired to change a circled number as shown in (A) of the figure to a bracketed number as shown in (B) of the same figure, there are the following two types of changing methods.
[0005]
The first is a method in which the cursor is moved to a position where a circled numerical character is input, and a parenthesis is input from there. That is, move the cursor over “Circular Number 1” and enter “Parent Number 1”, then move the cursor over “Circular Number 2” and enter “Parent Number 2” Next, the cursor is moved over “circle number 3”, “parenthesis number 3” is input, and then overwritten sequentially.
[0006]
The second method uses a character replacement function, which is a basic function of document editing. “Circular number 1” is changed to “Parent number 1”, and “Circular number 2” is changed to “Parent number 2”. In this method, “circle number 3” is replaced with “bracket number 3” with.
[0007]
[Problems to be solved by the invention]
In the case of the first method, as shown in Display Example 1 in FIG. 6, when the cursor is currently over a numerical character, that is, “circle number 1”, another type of numerical character, for example, “parentheses” When a numeral “1” is entered, “parenthesis numeral 1” is entered in the document instead of the “circle numeral 1”, and the cursor moves to the next digit, as shown in display example 2 of FIG. Then, in order to change the next “circle number 2”, the cursor is moved over the “circle number 2”, and “parenthesis number 2” is input. Therefore, if there are 100 numerical characters in the document, it is necessary to search for all 100 characters one by one, move the cursor, and input an appropriate numerical character from there. Also, there was a possibility of forgetting to input or making an input error.
[0008]
In the case of the second method, as compared with the first method, only a specific character existing in the document is automatically searched and replaced with the designated character. It is necessary to repeat the replacement function as many times as the maximum number of numerical characters used in (If the numerical characters are used in the document from "1" to "10", the replacement function is It must be repeated 10 times), but it still took time and effort, and could cause forgetting to replace.
[0009]
An object of the present invention is to enable conversion from one type of numeric character to another type of numeric character with a single operation.
[0010]
[Means for Solving the Problems]
Means of the present invention are as follows.
Numerical character storage means for storing numerical characters according to the type of numerical values, and storing each numerical character in each type according to the order of the numerical characters, and any numerical character on the document data consisting of a plurality of characters The type specifying means for specifying the type before the change as the first type, and specifying the type of the numerical character after the change as the second type, The document data is searched for a numerical character of a type that matches the specific first type, and an order acquisition unit that acquires the numerical order of the searched numerical character, and each of the specific second type numerical character The numerical character that matches the numerical order acquired by the order acquisition means, and replaces the read numerical character with the numerical character searched on the document data Value substitution means.
Therefore, when an arbitrary numerical character is changed to another numerical character different from the numerical character type on the document data composed of a plurality of characters, the type before the change is specified as the first type, The type of the numeric character after the change is specified as the second type, the numeric character of the type that matches the first type is searched on the document data, the numerical order of the searched numeric character is acquired, Among the two types of numerical characters, the numerical character that matches the acquired numerical order can be read, and the read numerical character can be replaced with the numerical character searched on the document data.
[0014]
【Example】
An embodiment of the present invention will be described below with reference to FIGS. 1A to 4B.
[0015]
FIG. 1A is a diagram showing a configuration of a word processor to which an embodiment of the present invention is applied. An input unit 10 is a key input device for inputting document data and various function commands. The operation signal output corresponding to each key is given to the input control unit 12. The input control unit 12 converts the input key operation signal into a predetermined code and holds it. The CPU 14 sequentially accesses and takes in the key code held in the input control unit 12.
[0016]
The CPU 14 controls the overall operation of the word processor in accordance with various programs stored in the program memory 16. That is, when document data is input from the input unit 10 via the input control unit 12, the CPU 14 stores the input document data in the text memory 18A of the RAM 18 or gives it to the display control unit 20 according to various programs. Display output on the text screen of the display unit 22.
[0017]
Further, when editing the contents of the text memory 18A by input from the input unit 10, if another type of numerical character is input from above the numerical character, the CPU 14 replaces the numerical character replacement in various programs. According to the program 16A, the contents of the text memory 18A are changed by referring to the numerical character table 24 using the I register 18B and the pointer 18C provided in the RAM 18. Then, the contents of the text memory 18A after the change are given to the display control unit 20 and displayed on the text screen of the display unit 22. Note that the numerical character table 24 stores parenthesis numerals, round numerals, uppercase Roman numerals, lowercase Roman numerals,... In association with each other in order from 1 as shown in FIG. . The I register 18B is for counting the number of characters in the numerical character table 24, and the pointer 18C is used as a conversion source and conversion destination for which type of numerical character in the numerical character table 24. It is shown.
[0018]
Next, the operation in such a configuration will be described.
[0019]
Conventionally, as shown in FIG. 6, when the cursor is on the numerical character “circle number 1” and another numerical character “parenthesis number 1” is input, Instead of “1”, the “bracketed number 1” was entered into the text and the cursor only moved to the next digit. On the other hand, in this embodiment, as shown in display example 1 of FIG. 2, when the cursor is currently on the “circle number 1” which is a numerical character, another numerical character is used. When a certain “1” in parenthesis is entered, as shown in Display Example 2, “1 in parenthesis” is entered on the text instead of “1” in circle, and the cursor moves to the next digit at the same time. , Other round numbers on the text are also converted to the corresponding parenthesis numbers. That is, "circle number 2" is automatically converted to "parenthesis number 2", "circle number 3" is automatically converted to "bracket number 3", and "circle number 4" is automatically converted to "bracket number 4" Is done.
[0020]
Such a conversion operation is performed as shown in the flowchart of FIG.
[0021]
That is, when any character is input on the text from the input unit 10, this flowchart starts. First, the character in the text memory 18A corresponding to the current cursor position is provided in the RAM 18 with the input character. After being saved in a buffer (not shown), the input character is stored in the text memory 18A (step S1). Next, it is determined whether another type of numerical character has been input from above the numerical character (step S2). If not, it is a normal character input process, and the process ends.
[0022]
On the other hand, if it is determined in step S2 that another type of numeric character has been input on a certain numeric character, pointer setting processing for setting the pointer of the numeric character table 24 is first performed in accordance with the numeric character replacement program 16A. (Step S3), character conversion processing is performed to replace all numeric characters of the same type as the numeric characters before input existing in the text with numeric characters of the same type as the numeric characters after input (step S3). S4) The process is terminated.
[0023]
FIG. 5B shows the pointer setting process in step S3.
[0024]
That is, first, the conversion source numerical character, that is, “circle number 1” saved in step S1 in the above example is searched in order from the top of the numerical character table 24 (steps S31 and S32). If there is a conversion source numerical character, a conversion source numerical character pointer indicating the type of the numerical character is set in the pointer 18C configured in the RAM 18 (step S33).
[0025]
Thereafter, the conversion destination numeric character pointer is set in the same manner. That is, the conversion destination numerical character from the top of the numerical character table 24, that is, “the parenthesis number 1” stored in step S1 in the above example is searched in order (steps S34 and S35). If there is a conversion destination numerical character, a conversion destination numerical character pointer indicating the type of the numerical character is set in the pointer 18C (step S36).
[0026]
Next, the character conversion process in step S4 will be described with reference to the flowchart of FIG.
[0027]
That is, first, a text pointer (not shown) indicating a character reading position in the text memory 18A is reset (step S41). If this text pointer does not point to the end of the text memory 18A (step S42), a character data check and target character conversion process as will be described in detail later is performed on the character pointed to by the text pointer. (Step S43), the text pointer is updated (Step S44), and the process returns to Step S42. That is, the entire text memory 18A is checked sequentially from the beginning, and if there is a character to be converted, it is converted.
[0028]
Here, the character data check and the target character conversion processing in step S43 are performed as shown in FIG.
[0029]
That is, first, the I register 18B configured in the RAM 18 is initialized to “0” (step S431). Among the numerical characters of the type indicated by the designated character of the text memory 18A pointed to by the text pointer and the conversion source numerical character pointer set in the pointer 18C of the numerical character table 24, the I register 18B It is determined whether or not the numerical character indicated by the value is the same (step S432). That is, in the above example, the character in the text memory 18A is compared with “1”.
[0030]
If they are not the same, the value of the I register 18B is updated (step S433), and the character in the numerical character table 24 indicated by the updated value of the I register 18B no longer has that type of numerical character. It is determined whether or not the END code indicates (step S434). If it is an END code, the process proceeds to step S44. If it is not an END code, the process returns to step S432, and a comparison with the next numerical character is performed. That is, the characters read from the text memory 18A are sequentially compared with “circle number 2”, “circle number 3”, “circle number 4”, and so on to determine whether or not they match.
[0031]
When it is determined in step S432 that they match, the designated character in the text memory 18A pointed to by the text pointer is indicated by the conversion destination numerical character pointer set in the pointer 18C of the numerical character table 24. Of the types of numeric characters, the numeric characters indicated by the value in the I register 18B are rewritten (step S435), and the process proceeds to step S44.
[0032]
With this processing, as shown in display example 2 of FIG. 2, “circle number 2” becomes “parenthesis number 2” and two “round numbers 3” become “parenthesis number 3”, respectively. Then, “circle number 4” is automatically rewritten to “bracket number 4”.
[0033]
As described above, numerical characters are used in the document to indicate the items in an easy-to-understand manner, and when it is desired to change the type of the numerical character, if only one numerical character is changed by inputting a normal character, Since all the corresponding numerical characters that exist are changed to the same type of numerical characters, it is possible to save time and effort in document editing and to eliminate the possibility of forgetting to change.
[0034]
It should be noted that the same function can be provided in a normal character replacement function (a function that replaces all search characters existing in a document with replacement characters by inputting a search character and a replacement character). For example, if “1” is used as the search character and “1” is used as the replacement character, not only all “1” will be replaced with “1”. At the same time, “circle number 2” is automatically replaced with “parenthesis number 2”, “circle number 3” is replaced with “bracket number 3”, and so on.
[0035]
In the above embodiment, when a new numerical character is overwritten, the stored numerical character is automatically converted to a new numerical character. Also good.
[0036]
In addition, the heading item may be converted by converting any of the small heading, the medium heading, and the large heading. For example, when “1” is converted to “1.” and “2” is converted to “2.”, the “circle number 1” used as the middle heading is changed to “parentheses”. It is also possible to convert “number 1” to “circle number 2” to “parenthesis number 2”.
[0038]
【The invention's effect】
According to the present invention, a plurality of characters can be converted from one type of character to another type of character related to the character with a single operation.
