Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a document output device such as a word processor.

[Prior Art] Conventionally, in a word processor, when reading and printing a dot pattern in a character generator that is expressed by a fixed font such as Mincho font, the dot pattern is a tilted character, a turning character, or a double-width character. It is possible to change to a character form such as the one described above. However, the changeable character form has been performed by selecting a desired character form from a plurality of character forms determined in advance by the manufacturer.

[Problems to be Solved by the Invention] In the case of changing a dot pattern by selecting a desired character form from a plurality of character forms as described above,
Since the selectable character forms are limited, there is a disadvantage that the user cannot print in any desired character form.

It is an object of the present invention, when outputting character data, that a character pattern based on basic character pattern information corresponding to a specified character is curvedly deformed into an arbitrarily designated curvilinearly deformed shape, and is curvilinearly deformed. Since the character pattern is expanded in the print buffer and printed out, the document data can be printed out.

[Means for Solving the Problems] As shown in the functional block diagram of FIG. 1, the means of the present invention prepares a plurality of characters, and for each of the characters, a character pattern that is the basis of the individual character. A character pattern information storage means for storing basic character pattern information for outputting a basic character pattern of a shape, a document storage means for storing document data composed of a plurality of characters, and when output of the document data is designated. Reading each character in the document data stored in the document storage means,
A document output including a printing means for converting each read character into a character pattern according to the basic character pattern information stored corresponding to each character, developing the character pattern in a print buffer, and printing out. In the apparatus, a character transformation instructing means for instructing a character transformation function for transforming the basic character pattern in a curved manner at a one-character level, and when the character transformation function is instructed by the character transformation instructing means, the character A curve transformation shape designating means for arbitrarily designating a curve transformation shape for vertically or horizontally transforming a basic character pattern, a character designating means for arbitrarily designating a character to be a curve transformation target, and this character designating means The basic character pattern information corresponding to the character specified by is read from the character pattern information storage means, and the character based on the basic character pattern information is read. Character pattern deforming means for deforming the turn curvilinearly into the curved deformed shape designated by the curved deformable shape designating means, wherein the character designated by the character designating means is transformed by the character pattern transforming means. It is characterized in that the modified character pattern obtained by the curve modification is expanded in the print buffer and printed out.

[Operation] The operation of the means of the present invention is as follows.

When the function for deforming the basic character pattern in a curved manner at the one-character level is instructed by the character deformation instructing means, the operator deforms the character pattern of each character in the vertical or horizontal direction in the curved deformation shape designating means. It is possible to arbitrarily specify the curved deformation shape for the above, and the character specifying means can arbitrarily specify the character to be the curved deformation target. Then, the character pattern transforming means reads the basic character pattern information corresponding to the designated character from the character pattern information storage means, and the character pattern based on the basic character pattern information is the curved transform shape designated by the curved transform shape designating means. The character designated by the character designating means is expanded in the print buffer with the transformed character pattern curvedly transformed by the character pattern transforming means and printed out.

[Embodiment] The present invention will be specifically described below based on an embodiment shown in FIGS. 2 to 7. This embodiment is applied to a word processor.

Structure (FIG. 2) FIG. 2 is a block circuit diagram showing the basic structure of the word processor. The CPU 11 controls various operations of the word processor according to a microprogram stored in advance. For example, the CPU 11 uses the key input unit 12
The document data input from is taken in, converted into kana-kanji, etc., and stored in the text memory 13. This text memory 13 is a memory for storing a document that stores a document in a character code format.The CPU 11 reads a character code from the text memory 13 in response to a print command from the key input unit 12, and the character generator outputs the character code. It is converted into a corresponding dot pattern using the constituent character pattern memory 14 and stored in the print buffer 15. The dot pattern stored in the print buffer 15 is printed on the storage paper set in the printer 16. In addition, character pattern memory
Reference numeral 14 has a known configuration for storing a dot pattern of 24 × 24 dot configuration for one character corresponding to various character codes. The printer 16 is a thermal printer, and its print head has a configuration having 48 thermal elements.

On the other hand, a liquid crystal touch keyboard 17 is provided in this word processor. In this liquid crystal touch keyboard 17, a liquid crystal display panel is arranged below a pressure-sensitive transparent touch keyboard, and while displaying a trace drawn with a pen or the like on the touch keyboard on the liquid crystal display panel, any character transformation can be performed. The line segment pattern is manually input. That is, the liquid crystal touch keyboard 17 is capable of inputting a coordinate position of 48 × 48 dots corresponding to the XY coordinate system, and the scale of this coordinate is determined by the broken line displayed on the liquid crystal display device constituting the liquid crystal touch keyboard 17. It is visually divided every 12 × 12 dots. Note that BP indicates the reference point of the XY coordinate system, the X axis is the 12th dot from the bottom, and the Y axis is the 12th dot from the left.
Located at the dot, these intersections become the reference point BP.
A square chain region (shown by hatching in the figure) of 24 dots above and 24 dots above the reference point BP is a character 24 × 24 dot structure fixedly stored in the character pattern memory 14. The vertical line segment pattern, which is similar to the dot pattern (hereinafter referred to as the basic dot pattern), is used to specify the amount of change in the horizontal direction of each dot with respect to the basic dot pattern. A horizontal line segment pattern (including a diagonal line and a curve extending in the X-axis direction) for designating the amount of change in the vertical direction of the dot is manually input.

Of the line patterns manually input from the liquid crystal touch keyboard 17, horizontal line segments are stored in a horizontal line segment memory 18, and vertical line segments are stored in a vertical line segment memory 19.

Each line segment pattern stored and held in the horizontal line segment memory 18 and the vertical line segment memory 19 is read out under the control of the CPU 11, and the number of horizontal dots is calculated based on the horizontal line segment pattern. The number of vertical dots is calculated based on the above and set in the corresponding horizontal dot number register 20 and vertical dot number register 21.

Further, the CPU 11 responds to the operation of the character change print key TK provided in the key input section 12 in response to the horizontal dot number register 20,
Based on the contents of the vertical dot number register 21, the horizontal size ratio and the vertical size ratio with respect to the basic dot pattern are obtained and given to the ratio data memory 22. Pattern compression,
The expansion unit 23 performs compression and expansion processing of the basic pattern based on the contents of the ratio data memory 22 to change the size of the basic pattern. The change pattern changed by the pattern compression / expansion unit 23 is controlled by the CPU 11 under the control of the work memory 2
Transferred to 4 or 25. In addition, work memory 24, 25
Is used when transforming the basic dot pattern. Further, the CPU 11 obtains the amount of change in the horizontal direction of each dot or the amount of change in the vertical direction of each dot with respect to the basic dot pattern for each dot unit based on the contents of the horizontal line segment memory 18 and the vertical line segment memory 19, and accordingly, The pattern in the work memory 24 or 25 is moved dot by dot to change the pattern form.

Overall Operation (FIGS. 3 and 4) When the character change print key TK is operated, the operation is executed according to the flowchart shown in FIG.

First, when a message indicating that a horizontal line segment for character deformation should be input is confirmed from the liquid crystal touch keyboard 17 and the horizontal line segment is manually input from the liquid crystal touch keyboard 17, the horizontal line segment pattern is stored in the horizontal line segment memory 18. (Step A1,
A2).

FIG. 4 shows the storage state of the horizontal line segment memory 18. The horizontal line segment pattern of the waveform manually input from the liquid crystal touch keyboard 17 has a maximum of 3 dots in the upward direction (plus direction) with the X axis of the basic dot pattern as a boundary. , A maximum of 4 dots change downward (minus direction).

When the horizontal line segment pattern input from the liquid crystal touch keyboard 17 is stored in the horizontal line segment memory 18 in this manner, CP
U11 obtains the horizontal dot number of the horizontal line pattern and sets it in the horizontal dot number register 20 (step A3). That is, the fourth
For the horizontal line segment pattern shown in the figure, the projection point on the X axis is the horizontal dot number, and in this case, the horizontal dot number is "32" dots.

Then, when the input process for the horizontal line segment pattern for character transformation is completed as described above, the same process is performed for the vertical line segment pattern (steps A4 to A6). That is, the vertical line segment pattern manually input from the liquid crystal touch keyboard 17 is stored in the vertical line segment memory 19, and the number of vertical dots is calculated based on the vertical line segment pattern in the vertical line segment memory 19. , Vertical dot number register 21 is set.

Next, in step A7, the text code to be printed out of the document data in the text memory 13 is designated. Then, the dot pattern for one character corresponding to this text code is read from the character pattern memory 14 (step A8). Then, a pattern output process, which will be described later, of storing the read pattern in the print buffer 15 is executed (step A9). When the dot pattern for one character is stored in the print buffer 15 in this way, the process returns from step A10 to step A7, and 1 is set for all characters for which printing is taken.
The above steps A7 to A9 are repeated character by character.

Pattern Output Process (FIGS. 5 and 6) FIG. 5 is a flowchart showing the specific contents of the pattern output process described above.

FIG. 6 shows a case where a vertical line segment pattern and a horizontal line segment pattern for character transformation in the shape as drawn on the liquid crystal touch keyboard 17 shown in FIG. It shows a process in which the basic dot pattern of "A" is sequentially changed based on the inputted vertical line segment pattern for character transformation and horizontal line segment pattern.

The flowchart of FIG. 5 will be described below with reference to FIG. This pattern output process is (1) a process of compressing and expanding the basic dot pattern in the horizontal direction, (2) a process of compressing and expanding in the vertical direction, (3) compression, and a process of deforming the expanded pattern in the vertical direction. , (4) The process of deforming in the left-right direction is sequentially executed.

(1) Check if the horizontal dot number (input horizontal dot number) set in the horizontal dot number register 20 matches the horizontal dot number (basic dot number) "24" of the basic dot pattern. Yes (step B1). Since the input horizontal dot number is “32” dots as shown in FIG. 4, the process proceeds to the next step B2, and the ratio to the basic horizontal dot number is calculated (horizontal dot number / 24), and is calculated by this. The ratio data thus obtained is set in the ratio data memory 22.
Then, the pattern compression / expansion unit 23 performs a process of compressing or expanding the basic dot pattern based on the content of the ratio data memory 22 to change the horizontal size of the basic dot pattern, and the pattern thus changed. Is transferred to the work memory 24 (step B3). In this case, since the horizontal dot number in the horizontal dot number register 20 is "32" dots, the basic dot pattern shown in FIG. 6 (A) is enlarged in the horizontal direction, as shown in FIG. 6 (B). , Work memory
An enlarged pattern of horizontal 36 dots and vertical 24 dots is stored in 24.

The pattern compression and expansion processing is performed by a known method. For example, taking pattern compression as an example,
In horizontal compression of 1/2, horizontal lines are compressed to 1/2 length by thinning out one dot in the horizontal direction, and black lines, that is, dot-on When the width is 1 dot, the dot is thinned so that it is 1 dot on as it is, when it is 2 dots, it is 1 dot on, and when it is 3 dots, it is 2 dots on so that compression is performed. The pattern enlargement process is performed by inserting dots.

On the other hand, the horizontal dot count in the horizontal dot count register 20 is "24".
If it is a dot, the pattern is not compressed or expanded, and the basic dot pattern is transferred to the work memory 24 (step B4).

(2) It is checked whether or not the vertical dot number set in the vertical dot number register 21 matches the vertical dot number (basic vertical dot number) "24" of the basic dot pattern. Since the vertical line pattern manually input as shown in FIG. 2 has a 24-dot structure, the process proceeds to step B8, and the pattern in the work memory 24 is transferred to the work memory 25 as it is. FIG. 6C shows pattern data in the work memory 25 in this case.

If the number of vertical dots is not "24", the ratio calculation (the number of vertical dots / 24) similar to the above is performed (step B
6). Then, the process of compressing and expanding the pattern in the work memory 24 based on the contents of the ratio data memory 22 is executed, whereby the vertical size of the basic dot pattern is changed and the changed pattern is transferred to the work memory 25. (Step B7).

(3) It is checked whether all the dots of the horizontal line pattern stored in the horizontal line segment memory 18 are located on the X axis of the reference dot pattern, that is, whether or not there is a change in the horizontal line segment ( Step B9). Since the horizontal line pattern as shown in FIG. 4 has changed with respect to the basic dot pattern, the process proceeds to the next step B10 and the horizontal line pattern 1
The process of moving the corresponding dot row of the pattern in the work memory 25 up and down and transferring it to the work memory 24 according to the amount of change in dots is sequentially repeated dot by dot until the end of all dot rows is detected in step B11. FIG. 6 (D) is the fourth
The dot pattern in the work memory 25 is vertically deformed by vertically moving the enlarged dot pattern shown in FIG. 6C corresponding to the horizontal line pattern shown in FIG.
The deformation pattern is stored in the work memory 24.

When it is detected in step B9 that the horizontal line segment has not changed, the pattern in the work memory 25 is transferred to the work memory 24 as it is (step B12).

(4) If the vertical line pattern in the vertical line segment memory 19 changes with respect to the Y axis of the reference dot pattern, step B13
This is detected by the process, and the corresponding dot row of the pattern in the work memory 24 is moved to the left or right according to the change amount of one dot of the vertical line pattern, and the modified pattern is transferred to the work memory 25 (step B14). Is sequentially repeated dot by dot until the end of all dot rows is detected in step B15. FIG. 6 (E) deforms the dot pattern in the work memory 24 in the left / right direction by moving the dot pattern shown in FIG. 6 (D) in the left / right direction corresponding to the vertical line pattern shown in FIG. , This deformation pattern is work memory 25
Shows the state stored in.

When it is detected in step B13 that there is no change in the vertical line segment, the dot pattern in the work memory 24 is transferred to the work memory 25 as it is (step B16).

Then, when the transformation process for the vertical line segment ends, the dot pattern in the work memory 25 is transferred to the print buffer 15 (step B17). As a result, FIG. 6 (A)
The basic dot pattern as shown in FIG. 6 is transformed into a dot pattern and printed as shown in FIG.

As described above, in this embodiment, the basic dot pattern fixedly stored in the character pattern memory 14 is changed to an arbitrary form by manually inputting an arbitrary horizontal line pattern or vertical line pattern from the liquid crystal touch keyboard 17. It can be printed. For example, the basic dot pattern of “mountain” may be vertically transformed as shown in FIG.
As shown in FIG. 7 (B), it is possible to print by deforming it into a curved shape.

Modified Example (1) In this embodiment, the horizontal line segment and the vertical line segment pattern for character transformation are manually input using the liquid crystal touch keyboard 17, but these can be input by operating the cursor key, for example. The input means may be arbitrary, or may be optical input using a light pen or the like.

(2) Further, in the above-mentioned embodiment, the basic dot pattern of 24 × 24 dot configuration is changed into an arbitrary form within the range of 48 × 48 dots, but the dot scale is arbitrary.

According to the present invention, the character pattern based on the basic character pattern information corresponding to the designated character is transformed into the arbitrarily designated curved deformation shape, and the transformed character pattern is transformed into the curved shape. Since the data is expanded in the print buffer and printed out, when the document data is printed out, the variations in the character form are remarkably rich and the document expression is rich in individuality.
