DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First to third embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a main part of a document creating apparatus using the character pattern creating apparatus according to the first to third embodiments, and FIG. 2 is a concept for explaining the operation of the first embodiment. FIGS. 3, 3 and 4 are flowcharts for explaining the operation of the first embodiment.

As shown in FIG. 1, the present apparatus includes a controller 1,
A keyboard 2, an input control unit 3, a display 4, a display control unit 5, a printer 6, a print control unit 7 and a font memory 8 are provided. The control unit 1 is for document creation / editing processing,
It is composed of a CPU that performs character pattern generation processing and controls each circuit that constitutes the document creation apparatus.

The keyboard 2 has a conversion key 2a, a character modification key 2b, a cursor key 2c and a print mode key 2d in addition to various character keys. The input control unit 3 converts various key input signals input from the keyboard 2 into key codes. The display 4 is a display device having a liquid crystal panel display, for example, and displays document data under the control of the display control unit 5.

The printer 6 is a printing device that executes a printing process according to the character pattern developed in the print pattern buffer 12 under the control of the print control unit 7. The font memory 8 is a ROM that stores font data (character patterns) corresponding to character codes. The font memory 8 stores font data of plural font types.

The apparatus further includes a character decoration information buffer 9, a pattern expansion information buffer 10, a document information buffer 11, and a print pattern buffer 12.
The character modification information buffer 9 is a buffer memory that stores character modification information in a character string that forms the created document information and character modification information indicating the content of the character modification. The pattern development information buffer 10 is a buffer memory that stores various pattern development information for developing a character pattern in the print pattern buffer 12. The pattern expansion information includes a character code, character modification content, font type, and pattern position coordinates (X coordinate, Y coordinate).
Information such as coordinate) and character size (vertical and horizontal width of pattern expansion).

The document information buffer 11 is a buffer memory for storing a character string forming the created document information as a character code string (document data). The print pattern buffer 12 is a buffer memory for developing a character pattern corresponding to each character code of document data in the print mode. Next, the operation of the first embodiment will be described.

The CPU 1 executes a document creation process according to the character string input from the keyboard 2 (steps S1 and S2 in FIG. 3). That is, the CPU 1 executes a kana-kanji conversion process on the hiragana character string input by operating the character keys of the keyboard 2 according to the operation of the conversion key 2a.

The CPU 1 develops the document data consisting of the character code string of the kanji character string (kanji and hiragana) obtained by the kana-kanji conversion processing in the document information buffer 11 (step S3). The CPU 1 displays the character pattern corresponding to each character code stored in the document information buffer 11 on the screen of the display 4 (step S4). At this time, the CPU 1 reads the character pattern corresponding to the character code from the font memory 8 and expands it in a display memory (not shown). The display control unit 5 displays the character pattern stored in the display memory on the screen of the display 4.

Here, in the character string displayed on the screen of the display 4, by operating the character modification key 2b and the cursor key 2c of the keyboard 2, the designated character is instructed to modify the shaded character according to the present invention ( YES in step S5). The CPU 1 stores the character decoration information indicating the shaded character decoration for each designated character code in the character decoration information buffer 9 (step S6).

Next, the print mode key 2d of the keyboard 2
When is operated (YES in step S7), the CPU 1 executes print processing. In the print mode, the CPU 10 displays the print format menu on the screen of the display 13.
The print format menu displays items such as a print range (full text print, page print, etc.), font type, print speed, and the like.

When a predetermined item is designated from the print format menu by the cursor key 2c of the keyboard 2, the CPU
1 is the character pattern corresponding to the character code to be printed,
The pattern development information to be developed in the print pattern buffer 12 is stored in the pattern development information buffer 10 (step S8).

In this case, for the character for which the shaded character modification is designated, the CPU 1 creates the pattern development information for two characters for one character and stores it in the pattern development information buffer 10 ( YES in step S9, S1
0). That is, in the embodiment, since the original character pattern and the reverse pattern thereof are combined and the original character pattern is slid vertically and horizontally to generate the shaded character pattern, the original character pattern and the reverse pattern are generated. The pattern development information corresponding to each of these is created.

The CPU 1 reads the font data corresponding to the designated character code from the font memory 8 based on the pattern development information, and develops a desired character pattern in the print pattern buffer 12 (step S11). Specifically, as shown in FIG. 2 (A), for example, a character pattern of the letter "A" is developed. In FIG. 2A, the shaded portion is a black dot and the background portion is a white dot.

Further, the CPU 1 creates an inverted pattern of the expanded original character pattern and expands it in the print pattern buffer 12 (step S12). Specifically, FIG.
As shown in (B), the original character pattern of the letter "A" is inverted into white dots, and the background is inverted into black dots (hatched portion). Next, the CPU 1 synthesizes the original character pattern with the inverted pattern and slides it up, down, left and right by a predetermined amount based on the pattern development information (step S13).
Specifically, as shown in FIG. 2C, the original character pattern 20a of the letter "A" that is vertically and horizontally slid is developed with respect to the white dot inversion pattern 20b.

The CPU 1 causes the printer 6 to print the shaded characters based on the character patterns developed in the print pattern buffer 12 (step S14).
Therefore, in the same embodiment, as shown in FIG.
The character pattern 20a with a white shadow corresponding to the reverse pattern 20b can be printed.

For normal characters that are not decorated with shaded characters (NO in step S9), CPU 1
Reads out font data corresponding to the designated character code from the font memory 8 based on the pattern development information, and develops a desired character pattern in the print pattern buffer 12 (step S16). That is, as shown in FIG. 2A, for example, a character pattern of the alphabetic character "A" is developed.
Based on this character pattern, the printer 6 executes the normal character printing process (step S14).

In the second embodiment, in the document creating apparatus shown in FIG. 1, the print pattern buffer 12 is shown in FIG.
As shown in, the background buffer 12a and the shadow buffer 12b
And each area of the character buffer 12c. In addition,
Other configurations are the same as those of the document creating apparatus shown in FIG.

In the second embodiment, each of the buffers 12a to 12c of the print pattern buffer 12 is used to generate and print a character pattern with a shadow on the left side of the character, for example.
That is, as shown in FIG. 5B, the CPU 1 creates a background pattern (for example, a horizontal striped pattern) in which the character pattern of the character for which the shaded character modification is designated (here, the letter A) is removed. In this case, the dotted line character pattern shown in FIG. 5B indicates that the pattern has been removed, and is not displayed on the screen of the display 4.

Next, the CPU 1 creates a shadow pattern to the left of the character pattern, as shown in FIG. 5 (C). Further, as shown in FIG. 5D, the shadow pattern is removed to create, for example, a vertical striped character pattern. Then, the CPU 1 synthesizes the created background pattern, shadow pattern, and character pattern to generate a character pattern with a shadow on the left side, as shown in FIG.

This character pattern generation processing is shown in FIGS.
Will be described. First, YES in steps S1 to S9 in FIG. 3 until the document creation process and the designation of the print mode.
The process is similar to Therefore, for a normal character that is not decorated with a shaded character, step S16 is performed.
The process shown in is executed.

As shown in step S20 of FIG. 6A, the CPU 1 clears the background buffer 12a of the print pattern buffer 12 (FIG. 6B). If the background of the character pattern is white (YES in step S21)
S), the background pattern creation process is not executed. The background pattern is specified (horizontal pattern here), for example, on the keyboard 2
This is performed when the shaded character modification is instructed to the designated character by the operation of the character modification key 2b or the print format menu when the print mode key 2d is operated.

When the background pattern is designated (NO in step S21), the CPU 1 develops a horizontal background pattern in the background buffer 12a as shown in FIG. 6C (step S22). The character pattern corresponding to the designated character is removed from the background pattern developed in the background buffer 12a (step S23).

Here, the CPU 1 obtains the information on the character pattern to be removed from the pattern development information of the designated character stored in the pattern development information buffer 10. That is, the character pattern removal processing is executed based on the pattern development information.

Further, the CPU 1 has the functions shown in FIGS.
As shown in, the pattern in which the character pattern is shifted to the right is removed (step S24). As a result, in the background buffer 12a, the same character pattern is combined and the background pattern obtained by removing the pattern in which one is relatively slid to the right is developed.

Further, as shown in step S25 of FIG. 7A, the CPU 1 clears the shadow buffer 12b of the print pattern buffer 12 (FIG. 7B). Here, if the shadow of the character pattern is white (YE in step S26)
S), the shadow pattern creation process is not executed.

When the shadow pattern is designated (NO in step S26), the CPU 1 causes the shadow pattern (black dot) to be added to the right side of the character and the character corresponding to the designated character, as shown in FIG. 7C. Performs AND processing with the pattern,
The pattern, which is the result of the processing and is formed by the common part of the patterns, is expanded in the shadow buffer 12b (step S2
7). Further, the CPU 1 removes the pattern that is slid to the right from the pattern (here, the letter A) developed in the shadow buffer 12b (step S2).
8). That is, specifically, as shown in FIG. 7D, the shadow pattern attached to the right side of the original character pattern is developed in the shadow buffer 12b.

Next, as shown in step S29 of FIG. 8A, the CPU 1 clears the character buffer 12c of the print pattern buffer 12 (FIG. 8B). If the character pattern is white (there is no character pattern) (YES in step S30), the character pattern creation process is not executed.

When the character pattern of the designated character exists (NO in step S30), the CPU 1 executes the process shown in FIG.
As shown in, the character pattern of the designated character is expanded in the character buffer 12c (step S31). At this time, CP
U1 reads the font data corresponding to the character code from the font memory 8 on the basis of the pattern expansion information of the specified character, and expands the character pattern.

Further, as shown in FIG. 8D, the CPU 1 shifts the character pattern developed in the character buffer 12b (here, the letter A) to the right (step S3).
2). The CPU 1 executes an AND process of the character pattern shifted to the right and a preset character pattern (vertical pattern in this case) pattern, and the character pattern pattern which is the result of the process is formed in the character buffer. 1
2c (step S33). Here, the designation of the character pattern pattern (here, the vertical pattern) is performed when the shaded character modification is instructed to the specified character by operating the character modification key 2b of the keyboard 2, or the print mode key is used. It is performed by the print format menu in the 2d operation.

Then, the CPU 1 executes a combining process as shown in FIG. 9 (A). That is, when the shadow is not white (NO in step S34), the CPU 1 develops the background pattern developed in the background buffer 12a (the pattern shown in FIG. 6E) and the shadow pattern developed in the shadow buffer 12b (FIG. 7). The OR processing with the pattern shown in (D) is executed (step S35). The CPU 1 develops a composite pattern as a result of the OR processing as shown in FIG. 9B in the background buffer 12a.

Further, the CPU 1 has the background buffer 12a.
Shadow, background composite pattern and character buffer 1
The OR processing with the character pattern developed in 2c (the pattern shown in FIG. 8E) is executed (N in step S36).
O, S37). The CPU 1 is the result of the OR processing shown in FIG.
The synthetic pattern as shown in FIG.
Expand to a.

The CPU 1 causes the printer 6 to print the shaded character based on the character pattern developed in the background buffer 12a of the print pattern buffer 12 (step S14). Therefore, in the same embodiment, as shown in FIG.
As shown in (C), it is possible to print a character pattern having a horizontal striped background and a black shadow on the left side.

The third embodiment is a document having a function of adjusting the shadow width of the shaded character pattern created by the first embodiment or the second embodiment according to the font type of the character pattern. It is a creation device. Therefore, in the third embodiment, as shown in FIG. 10, in the document creation apparatus shown in FIG. 1, a shadow width value calculation unit 30 and a memory 31 storing a font type basic shadow width magnification table are newly added. ..
The rest of the configuration is the same as that of the document creation device shown in FIG.

In the third embodiment, when the CPU 1 is instructed to modify a specified character with a shaded character by operating the character modifying key 2b and the cursor key 2c of the keyboard 2,
The character decoration information indicating the shaded character decoration of the character code is stored in the character decoration information buffer 9. The character code string of the created document data is stored in the document information buffer 11.

Next, the print mode key 2d of the keyboard 2
When is operated, the CPU 1 executes print processing. In the print mode, the CPU 10 displays the print format menu on the screen of the display 13. With the print format menu,
The cursor key 2c of the keyboard 2 is operated to set items such as vertical writing / horizontal writing of print characters, font type, and character magnification (step S40 in FIG. 11). Furthermore, CPU1
Sets the pattern expansion information such as expansion position, deformation size (enlargement / reduction), and line width required when expanding the character pattern, and stores it in the pattern expansion information buffer 10 shown in FIG. 1 (step S41).

The CPU 1 reads the font data corresponding to the designated character code from the font memory 8 based on the pattern development information, and develops the character pattern in the print pattern buffer 12. The developed character pattern is subjected to a shadowing process by the method of the first embodiment or the second embodiment to develop a shadowed character pattern.

Here, in the third embodiment, the shadow width value calculation unit 30 sets the basic value of the shadow width based on the basic character size (for example, full width) of the character pattern to be developed (step S42). .. The shadow width value calculation unit 30 performs the correction processing of the shadow width value based on the set character magnification (double angle, quadruple angle, etc.) (step S43). The correction process of the shadow width value based on the basic value of the shadow width and the character magnification is executed by a table prepared in advance.

Next, the shadow width value calculation unit 30 refers to the font type basic shadow width magnification table 31 to obtain the basic shadow width magnification corresponding to the font type of the character pattern to be developed, and to calculate the basic shadow width. The correction process of the shadow width value is performed by the magnification (step S44). The CPU 1 synthesizes the shadow width pattern of the shadow width set by the correction processing of the shadow width value of the shadow width value calculation unit 30 and the character pattern, and the print pattern buffer 12
Expand to.

Therefore, for example, when developing the Mincho type character pattern (here, the Chinese character is excellent) shown in FIG. 12A and the Gothic type character pattern shown in FIG. A shaded character pattern with a proper shadow width can be developed.

[0050]

As described above in detail, according to the present invention, in a method of outputting a character pattern based on a dot pattern for each character code, firstly, an inverted pattern of the expanded original character pattern is created. The white shaded character pattern can be developed by synthesizing the reverse character pattern and the original character pattern and sliding the original character pattern vertically and horizontally with respect to the reverse pattern.

Secondly, by creating and synthesizing the background pattern, shadow pattern, and character pattern corresponding to the designated character, for example, a shaded character pattern with a shadow on the left side can be developed.

Third, the shadow width of the shaded character pattern can be adjusted according to the font type of the character pattern.
Therefore, it is possible to develop a shaded character pattern having an appropriate shadow width according to the font type.

Since such various shaded character patterns can be developed, it is possible to diversify the character printing by executing the printing process based on this shaded character pattern.
