Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing device such as a word processor having a graphic display device, and more particularly to a superscript (superscript character) / subscript (subscript character) function.

[0002]

2. Description of the Related Art Conventionally, in this type of document processing apparatus,
It is already known that characters of superscript / subscript can be input. In this case, the input character size was automatically determined by each document processing program.
Therefore, the text size of the superscript and the subscript on the document screen was uniform.

[0003]

However, not everyone is convinced in the document layout with respect to the automatically determined character size of the superscript and subscript. There was a strong demand that the font size of the superscript and subscript could be changed according to preference.

[0004]

In order to achieve this object, a document processing apparatus capable of setting / changing a superscript / subscript character size of the present invention outputs a graphic display to a display device or a graphic printable printer. In the document processing apparatus, the script adding means for adding the attribute of the superscript or the subscript to the input character, the character size setting changing means for selecting any one of a plurality of designated character sizes, and the character Output means for outputting to the display device or a printer the input characters having the script attribute added by the script adding means based on the character size information selected by the size setting changing means in a predetermined character size.

[0005]

According to the document processing apparatus of the present invention having the above-mentioned configuration, which is capable of setting / changing the superscript / subscript character size, the attribute of the superscript or the subscript with respect to the input character is added to the input character by the script operation by the operator While the character size is added, any character size is selected and set from the plurality of designated character sizes by the character size setting changing means. Then, the input character with the superscript or subscript attribute added in the character size selected and set by the character size setting changing means is output to the display device or the printer by the operation of the operator. The character size setting changing means includes not only selecting one of the plurality of designated character sizes but also changing the once selected character size to another character size. Further, the new selection is grasped by the concept of "setting" and is expressed as "character size setting changing means".

Various keys such as 7e are provided in the key group 17.

Next, the electric system and the like of this embodiment will be described with reference to the block diagram shown in FIG. Each process is performed by being driven and controlled by the electronic control unit 30 incorporated in the word processor 1. The electronic control unit 30 includes a well-known CPU 31, a ROM 32 for preliminarily storing a program for controlling document creation, font data for display or printing, and various data, and R for temporarily storing print data and the like.
AM 33, a key interface section 34 for interfacing with the keyboard 7, the CRT display device 3
A CRT controller 35 for controlling output to the printer, a printer interface unit 36 for interfacing with the printer 5, and the like. CPU31 is R
According to a program stored in the OM 32, a data signal is input from the keyboard 7 as necessary, and various document processes are performed by driving the print ribbon, driving the print head 13, driving the paper 11 to the printer 5, and the like.

An example of inputting subscript characters in the above document creating apparatus will be described with reference to FIG. Now, "H ₂
Suppose you enter "O". First, in step 1 (S1), the normal character "H" is input by a character input operation by the operator. Next, enter the subscript character "2", but the operator enters the subscript setting key 1
By operating 7b, the subscript MENU is displayed on the display screen (step 2). The character size is specified according to this subscript MENU. The character sizes "1/2", "1/3", and "3/4" respectively represent the ratio with the normal character size, that is, the ratio with the size of the character positioned immediately before the cursor. In this example, the size of the input character “H” is shown.

When the operator designates the character size, the size of the character to be input next is represented by the size of the cursor shape (step 3). Then, when "2" is input in step 4 (S4), the subscript characters are displayed in the designated size. Step 5
The designation of the subscript is turned off in (S5), and the cursor shape returns to the original size in step 6 (S6). In step 7 (S7), the normal character "0" is input, and the input of the word including the subscript character is completed. It is also possible to change the character size of "2" by looking at the print result and the layout on the display. In this case, move the cursor to the subscript character on the screen and set the subscript setting key 1
This is done by operating 7b again to display the subscript MENU on the screen and again specifying the character size.

FIG. 4 shows an example of how the subscripted input text is stored in memory. By inserting a flag indicating a subcode and a size before and after the subscript character string, the substate can be recognized. For example, flag 1 is "1/2" character size, flag 2 is "1/3" character size, and flag 3 is "3/4".
This is executed by encoding data such as the character size and setting or changing the character size by recognizing the set flag.

FIG. 5 is a flowchart showing the procedure for inputting the subscript characters described in FIG. First, after accepting a key input in step 11 (S11), it is determined in step 12 (S12) whether the super script setting key 17a or the sub script setting key 17b is operated. In the above example, when the input operation of the character key “H” is first performed, NO is displayed.
Then, the process proceeds to step 21 (S21). Then, in step 21, it is determined whether the character code is a character code.
Proceed to 22). In this step 22, it is determined whether the mode is the super script mode or the sub script mode. However, in the case of inputting the above-mentioned "H" character, it is determined as NO in this step 22, so the next step 31 (S3)
Go to 1). In this step 31, the font data of the current size of the character code is selected and the display position is set to the normal character position. Then, in step 24 (S24), character display processing is performed.

When the subscript character "2" is entered next, the subscript setting key 17b is turned on, so that the answer is YES in step 12, and the process proceeds to step 13 (S13). In this step 13, ON / OFF of superscript designation or subscript designation
Also, a character size setting or changing process is performed. It goes without saying that in the first flow, the subscript mode flag is set to the ON state and the operation of selecting the character size is performed.

Next, returning to step 12, when the subscript character "2" is input, it is determined to be NO in this step 12, the character code is determined in step 21, and the process proceeds to step 22. This step 22
Then, since the input of "2" is in the subscript mode, YES is determined and the process proceeds to step 23 (S23). Then, in this step 23, the font data of the designated size of the character code is selected and the display position is set to the subscript position. Then, in step 24, the display process of the subscript character "2" is performed.

Next, returning to step 12, since the subscript setting key 17b is turned on, the determination is YES and the process proceeds to step 13. At this step 13, however, the subscript mode OFF process is performed. Finally, the input operation of the ordinary character "0" is performed, but the process proceeds from step 12 to step 21, and the processing is executed in order from step 22, step 31, and step 24 to complete the character input operation. If it is determined in step 21 that the code is not a character input code, another code process is being performed, and the process proceeds to step 41.

In the above embodiment, the subscript characters are mainly described, but it is possible to process a superscript character, for example, a character such as "x ² y" by the same operation. It is also clear from.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, when the superscript character or subscript character size is specified, the size is specified as a ratio to the size of the character positioned immediately before the cursor, but the character size itself is specified, for example, the number of points. May be specified.

[0019]

As is clear from the above description, the character size of the superscript or subscript of the present invention can be set / changed at any stage. The effect is that you can select the character size that is most suitable for the layout.
