BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus having a function of character modification, and more particularly to a function of making a part of characters in a created or input document a blind letter.

[0002]

2. Description of the Related Art Since a conventional document creating apparatus has various functions set with a focus on reading a created document,
There was no function to make part of the document displayed on the screen unreadable. However, even though the conventional document creation device also has a function called character modification that applies various modifications to some characters in the document displayed on the screen, some of the characters are included in this character modification function. There was no function to turn a blindfold. Therefore, when creating a fill-in-the-blanks question in an educational document teaching material, etc. using a conventional document creation device, there is no such hiding function, so do not enter words or phrases from the beginning with spaces etc. I had to keep it. However, this makes it difficult to know what words and phrases should be originally input in the space, which imposes a burden on the creator and makes it difficult to create the above-mentioned educational text materials. It was

Therefore, by modifying a part of the characters by using the above-mentioned character modifying function, it is possible to create a function of making these characters a blank character. However, since the conventional character modification function does not remember which character is modified as a group after the modification of the character is once completed, the above-mentioned character confirmation function is used to confirm the character that is a blank character. When canceling the modification, the modification range of the character had to be newly designated. In this case, when creating the above-mentioned filling problem, it takes a lot of time to remove the modification for confirming the blank characters of the filling portion, and there is a drawback that the document creation efficiency becomes very poor.

[0004]

As described above, the conventional document creating apparatus does not have a function of making a part of a document created and displayed on the screen a blank character. It is not possible to easily create the above-mentioned fill-in-the-blank problem while making a part of the letters blank letters and confirming these letters in the blank letters when creating, and it is troublesome and time-consuming to create such a document. was there.

In view of the above, the present invention eliminates the above-mentioned drawbacks and allows an arbitrary character in a document displayed on a screen to be turned into a blank by a simple operation, and then the blank can be displayed and confirmed by a simple operation. It is an object of the present invention to provide a document creation device and a method of hiding letters that can be used.

[0006]

According to the present invention, in a document creating apparatus for displaying a created or input document on a screen of a display, a designating unit for designating a specific area in the document,
A storage unit that stores a selection unit that selects a character included in the area designated by the designation unit, and document management information that indicates that one or more characters selected by the selection unit are the same character group. A group selecting means for selecting one or a plurality of character groups from the character group of the character management information stored by the storing means, and a character of the character group selected by the group selecting means on the screen. It has a configuration including an erasing means for making it unreadable and a display means for making the characters of the character group selected by the group selecting means readable on the screen.

[0007]

In the document creating apparatus of the present invention, the designating means designates a specific area in the document. The selecting means selects a character included in the area designated by the designating means.
The storage means stores document management information indicating that one or a plurality of characters selected by the selection means are the same character group. The group selection means selects one or a plurality of character groups from the character groups of the character management information stored by the storage means. The erasing means makes the characters of the character group selected by the group selecting means unreadable on the screen. The display means makes the characters of the character group selected by the group selection means readable on the screen. Thus, by simply pointing the character group selected by the group selecting means with a pointing device or the like, the character group can be easily converted into a readable state or an unreadable state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a document creating apparatus of the present invention. Reference numeral 1 is a CPU that performs document creation processing according to a program in the control program memory 2, 2 is a control program memory that stores procedures for performing document creation processing, and 3 is information that is necessary for the CPU 1 to perform document creation processing. A RAM for storage, 4 is a keyboard for outputting a code indicating which key is pressed, 5 is a pointing device for designating characters and areas on the screen of the display device 6, 6 is a display device for displaying a document on the screen, 7 is an output code obtained from a keyboard or data from a pointing device is output to the data bus 8 or
An input / output controller for sending the above display data to the display device 6, 8 is a data bus for transmitting data, and 9 is an address bus for transmitting an address.

Next, the operation of this embodiment will be described. The CPU 1 shown in FIG. 1 performs a document creation process according to a program stored in the control program memory 2. The document thus created is expanded as a display image on the RAM 3, and at the same time, various accompanying document management information is also read.
Stored on AM3. Various instructions relating to the document creation are transmitted from the keyboard 4 to the CPU 1 through the input / output controller 7, and the created document is also displayed on the screen of the display device 6 through the input / output controller. Further, in editing a document, the Pontig device 5 (for example, a mouse) is used to indicate a specific place on the screen of the display device 6, and information necessary for calculating coordinates via the input / output controller 7 is used. Tells CPU1. still,
When saving the created document even after the device is powered off, CP
U1 stores the management information relating to the document on the RAM3 in an external storage device (magnetic disk or the like) not shown.

The operation of displaying some characters in the document created by using the document creating apparatus shown in FIG. The operation is basically performed by selecting the character "" using the pointing device 5 and changing the display state. The characters displayed on the screen of the display device 6 are managed by the character management table set in the RAM 3 as shown in FIG. In order to select a specific character to be a blank character displayed on the screen of the display device 6, the creator must use the pointing device 5 to specify an area including the corresponding character inside. As a result, the CPU 1 acquires the coordinates of the start point and the end point of the designated area based on the output of the pointing device 5.

FIG. 2 shows the above-mentioned area designation.
3 is a flowchart showing an operation of the CPU 1. First, in step 201, the starting point coordinates of the area on the screen of the display device 6 designated by the pointing device 5 are fetched, and in step 202, the ending point coordinates of the area on the screen designated by the pointing device 5 are fetched. . Thereafter, the CPU 1 searches for a character having a common point with the designated area among the characters in the character management table shown in FIG. Issue the character group number of
These data are registered in a predetermined area of the character management table. Next, the CPU 1 issues a region group number to the region designated by the pointing device 5 in step 204, and sets it in the RAM 3 as shown in FIG.
The area definition processing is completed by registering in the area management table as shown in FIG.

Here, FIG. 9 is a view showing an example of a region on the screen of the display device 6 designated by the pointing device 5. B is the region start point and B is the region end point. Figure 1
0 is a diagram showing the concept of the character area. B is the character region start point, B is the character region width, and C is the character region height. FIG. 11 is a diagram showing a character example in which a common point exists in a designated area. In this example, the letters "water" of "hydrogen" and the letters "elementary" have the same group number, and the letters "oxygen" of "acid" and the letter "elementary" may have the same group number. It is shown. At the above stage, since it is not associated with other areas already defined, a new area group number is issued as a single area and stored in the area management table shown in FIG. At the same time, the above character group number, area start point coordinates, and area end point coordinates are also registered, and the processing up to this point is the area definition processing.

In order to select a character whose display state is to be changed, an indirect method of first selecting an area as described above and selecting a character included in the area is used. The character group number must be issued in advance. The flowchart shown in FIG. 3 is a process for selecting a character group already defined as described above. First, in step 301, the CPU 1 obtains the coordinates on the screen of the display device 6 designated by the pointing device 5, and then in step 302, the coordinates are the start points of the respective areas in the area management table shown in FIG. From the end point coordinate data, it is determined which of the defined areas belongs to the point. If the point belongs to any of the areas, step 3
In step 03, the area group number of the corresponding area is read from the area management table, and then step 304 is proceeded to. However, if the acquired coordinates do not belong to any defined area, the character group selection processing is ended. On the other hand, CP
When U1 proceeds to step 304, the area specified by the area group number read in step 303 may be in the same group as other areas, so the entire area management table is checked and the same area is checked. Find all areas with group numbers and acquire all the character group numbers managed by each area. The processing up to this point is the character group selection processing.

FIG. 4 is a flow chart showing a region group selection process for redefining a plurality of independently defined regions as the same region group. CPU1 is step 401
After importing while confirming in step 402 that all area designation coordinates of a plurality of groups to be the same group selected by the user with the pointing device 5 are defined in the area management table in FIG. , Go to step 403. In step 403, the CPU 1 searches for the smallest one of the fetched area group numbers, re-registers the area group number of the area selected by the minimum value in the area management table of FIG. The selection process ends. Even if the character groups belong to different areas, if they are set to belong to the same area group by this area group selection processing,
By the character group selection process shown in the flowchart of FIG. 3, all the necessary character groups can be selected by one user's instruction operation using the pointing device 5.
By this area group selection processing, for example, the character group “hydrogen” and “oxygen” to which originally different areas shown in FIG. 11 belong.
If the character groups are associated with each other, both character groups can be selected at once by only specifying one of the areas.

FIG. 5 is a flow chart showing a process for making the character selected by the above process readable on the screen of the display device 6. First, in step 501, the CPU 1 determines whether or not all the characters selected by the area are displayed on the screen of the display device 6, and if not, the process proceeds to step 502, and if so, it is made readable. The process ends. At step 502, the CPU 1
The character group number corresponding to the area group number of the designated area is read from the area management table in the RAM 3 shown in FIG.
It is determined whether or not it matches any of the character group numbers registered in the character management table shown in FIG. 7 in FIG. 3, and if they do not match, the process returns to step 501, and if they match, the process proceeds to step 504. In step 504, the CPU 1 reads the character code corresponding to the character group number registered in the character management table shown in FIG. 7, displays it at the already registered position on the screen, and is readable. Conversion is performed, and the process returns to step 501. By such a readability process, the characters in the area designated by the user with the pointing device 5 are displayed and can be read.

FIG. 6 is a flow chart showing a process for making the character selected by the above process unreadable on the screen of the display device 6 (concealed character). First,
The CPU 1 determines whether or not all the characters selected in step 601 have been made invisible on the screen of the display device 6 and the unreadable process has ended. If not, the process proceeds to step 602. When it is finished, the obfuscation process is finished. In step 602, the CPU 1 causes the R shown in FIG.
The character group number corresponding to the area group number selected from the area management table in AM3 is read, and the character group number read in step 603 is registered in the character management table shown in FIG. It is determined whether or not any of the numbers matches, and if they do not match, step 6
Return to 01, and if they match, proceed to step 604. C
In step 604, the PU 1 reads the character code corresponding to the character group number registered in the character management table, makes it invisible from the position on the screen that is already displayed, and makes it unreadable. Step 60
Return to 1. By such an unreadable process, the character in the area designated by the pointing device 5 by the user becomes unreadable. Note that making a character unreadable means, for example, making the character color the same as the background color. To cancel the selected state of the character group once selected, after selecting the character group by the process shown in FIG. 3, the character management information having the character group number is read from the character management table shown in FIG. This is done by searching, erasing the contents of the character group number storage area, similarly finding the area information having that character group number from the area management table shown in FIG. 8, and performing processing to delete this area information. .

According to this embodiment, a character at an arbitrary position in the document displayed on the screen of the display device 6 is selected by the pointing device 5 and the selected character cannot be read on the screen. It can be easily and quickly converted into a readable state and vice versa. Therefore, by using this function, it is possible to extremely easily create an educational document teaching material such as a fill-in-the-blank problem. In particular, in this example, since the characters whose display should be changed simultaneously are collectively managed as a region or a region group, selection by the pointing device 5 is facilitated. Further, in the present embodiment, the mouse is used as an example of the pointing device 5, but a trackball, a slice pen or the like may be used. Alternatively, it is possible to use a cursor key which is a part of the keyboard.
