Abstract

PURPOSE:To change the preliminarily designated character size in accordance with the font so as to eliminate a dispersion of the size of a font design part depending on the font. CONSTITUTION:When a printing point number is designated and a printing font is instructed from an input device 3, the printing point number and the printing font are set in the corresponding printing point number storing area PPT and printing font storing area PFM within a work memory 8. At the printing time of a document, a CPU 1 changes the designated point number in the printing point number storing area PPT based on the ratio of the size of a font design part corresponding to the designated font set in the printing font storing area PFM and the size of a font design part corresponding to a reference font set beforehand.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document printing device in a word processor or the like.

[0002]

2. Description of the Related Art Conventionally, in a word processor, for example, when printing a document, the character size is 3.4 mm (10.5 points), 3.8 mm (12 points), 4.2 mm (13 points).
If you specify any number of printing points from (Points) etc. and also specify any printing typeface from Mincho typeface, writing brush type, pen typeface, etc., the document data of the specified typeface will be printed in the specified size. To be done. That is, regardless of the designated typeface, the document data is faithfully printed with the designated character size.

[0003]

If the document is printed as it is with the specified number of points, the print result will be large in character size even if printing is performed with the same number of printing points due to variations in the font design portion depending on the typeface. Give the impression that they are different. That is, FIG. 6 concretely shows font data of the same character size corresponding to Mincho typeface and writing brush type, and (A) is a font expressing the Chinese characters “new” and “year” in Mincho typeface. Data, (B) is font data in which the Chinese characters "new" and "year" are expressed with a writing brush. Here, each font data has the same character size of 48 × 48 dots, but the size of the font design portion (shown with a broken line) is greatly different depending on the Mincho font and the writing brush,
The writing brush is designed to be smaller than the Mincho type.
In particular, the writing brush of the "year" is extremely small. In this way, the size of the font design differs depending on the typeface even with the same character size. The numbers seemed to be different, and the printed result was unattractive. That is, FIG. 7 shows an example of printing in this case, and (A) shows the case of printing in Mincho type.
(B) is a case of printing with a writing brush, and the print results of both appear to be different in character size, even though the same number of print points is designated. As a result, for example, when the Mincho typeface and the brush typeface are mixed and printed, the print result becomes unattractive. An object of the present invention is to make it possible to change a character size designated in advance in accordance with a typeface in order to eliminate the variation even if the size of the font design portion varies depending on the typeface.

[0004]

Means for Solving the Problems The means of the first invention is as follows. The point number designating means designates the number of printing points, for example, an arbitrary number of points from 10.5 points, 12 points, 13 points and the like. The typeface designating unit designates a print typeface, and, for example, designates an arbitrary typeface from Mincho typeface, brush typeface, and the like.
The point number changing means is based on a ratio between the size of the font design portion corresponding to the typeface designated by the typeface designating means and the size of the font design portion corresponding to the predetermined reference typeface, and the point number designating means is provided. Change the number of print points specified by. Here, the ratio is, for example, a ratio in the same character size, which may be fixedly stored in advance or obtained by a ratio calculation. The means of the second invention is as follows. The kanji extraction means extracts kanji from the document data to be printed. The first size detecting means develops each kanji extracted by the kanji extracting means into font data corresponding to a predetermined standard typeface, and detects the size of the design portion of the font data. The second size detecting means develops each kanji extracted by the kanji extracting means into font data corresponding to a designated typeface designated in advance, and detects the size of the design portion of the font data. The first average value calculating means calculates the average value based on the size detected for each Chinese character by the first size detecting means. The second average value calculating means calculates the average value based on the size detected for each Chinese character by the second size detecting means. The ratio calculation means obtains a ratio of the average value calculated by the first average value calculation means and the average value calculated by the second average value calculation means. The printing point number changing means changes the preset printing point number based on the ratio obtained by the ratio calculating means.

[0005]

The operation of the means of the first invention is as follows. Now, assuming that the predetermined standard typeface is Mincho typeface and the printing typeface designated by the typeface designating means is the writing style, the point number changing means is the same as the size of the font design part corresponding to the writing style in the same character size. The number of designated printing points is changed based on the ratio with the size of the font design part corresponding to the morning type. The operation of the means of the second invention is as follows. Now, assuming that the predetermined standard typeface is Mincho typeface and the arbitrarily designated printing typeface is the writing typeface, the first size detecting means corresponds each kanji extracted by the kanji extracting means to the minchotypeface. The size of the design portion of the font data is detected while expanding the font data. Similarly, the second size detecting means develops each kanji extracted by the kanji extracting means into font data corresponding to the writing brush and detects the size of the design portion of this font data. Then, the first average value calculating means calculates the average value based on the size of the Mincho typeface detected for each Chinese character, and similarly, the second average value calculating means detects the average value for each Chinese character. The average value is calculated based on the size of the brush. In this way, when the average value of the font design portion of each Chinese character is obtained corresponding to the Mincho typeface and the writing brush type, the ratio calculation means obtains the ratio of each average value. Then, the print point number changing means changes the preset print point number based on the ratio obtained by the ratio calculating means. Therefore, even if there is a variation in the size of the font design portion depending on the typeface, in order to eliminate the variation, the predesignated character size can be changed according to the typeface.

[First Embodiment] A first embodiment will be described below with reference to FIGS. FIG. 1 is a block diagram of a word processor. The CPU 1 controls the entire operation of the word processor according to various programs stored in the ROM 2 or the like, and the input device 3, the display device 4, the printing device 5, and the external storage device 6 are connected to the CPU 1 as its peripheral devices. Has been done. In addition to storing various programs, the ROM 2 is provided with a character generator that stores font data.

The input device 3 is used to input document data, various function commands, the number of print points when printing document data, and a print typeface. The document data is displayed and output from the text screen of the display device 4, or is subjected to kana-kanji conversion or the like and stored in the document memory 7. Here, the input device 3
When a document save command is input from, the document data in the document memory 7 is transferred to the external storage device 6 and registered and saved.

The printing device 5 is composed of a thermal printer, and the CPU 1 changes the number of printing points designated in advance according to the designated printing typeface, and prints a document with a character size corresponding to the number of changed points. To do. At this time, the CPU 1 uses the work memory 8 to change the number of printing points. The work memory 8 will be described later,
X size storage area CHX, Y size storage area CHY, character number storage area NUM, read start position storage area TOP, document capacity storage area CAP, read character storage area CHR, cumulative X size storage area ACX, cumulative Y size storage area ACY, Standard typeface average size storage area AVS, designated typeface average size storage area AVA,
The print point number storage area PPT and the print format storage area PFM are provided.

Next, the operation of this embodiment will be described. FIG. 2 is a flowchart showing an outline of the operation when printing a document.
First, when the number of print points, the print typeface, etc. are input from the input device 3, the input print point number, the print typeface is the corresponding print point number storage area PPT in the work memory 8,
It is set in the print format storage area PFM (step A1).
Then, the CPU 1 executes the average character size calculation process according to the flowchart of FIG.
2), the document print processing is executed according to the flowchart of FIG. 4 (step A3).

FIG. 3 is a flow chart showing the average character size calculation process. First, the CPU 1 refers to the print format storage area PFM in the work memory 8, and the print font arbitrarily designated in advance is the reference font (this embodiment). In (Mincho type), it is checked (step B1). Here, if the reference typeface is designated, the process exits from the flowchart of FIG. 3. However, if a typeface other than the reference typeface such as a brush typeface is designated, the process proceeds to step B2 to set the reference typeface. It is selected as a processing target of the average character size calculation processing. Next, as an initialization process, the X size storage area CHX, the Y size storage area CHY, and the character number storage area NUM in the work memory 8 are cleared (step B3), and the document data to be printed is read character by character from the beginning. The start position is set in the read start position storage area TOP (step B4). Then, the document capacity (total number of characters) to be printed is set in the document capacity storage area CAP (step B).
5).

When such initialization processing is completed,
In step B6, data (character code) for one character is read from the document to be printed according to the value of the read start position storage area TOP and set in the read character storage area CHR. Check (step B7). If the read character is not a kanji character, the value of the read start position storage area TOP is updated to read the next character code (step B12), and the value of the document capacity storage area CAP is checked. "1" is subtracted from this to update the document capacity (step B13). As a result, the document capacity is "0".
That is, it is checked whether all the document data to be printed have been read (step B14). If the reading has not been completed, the process returns to step B6. Hereinafter, similarly, the above-described operation is repeated until the Chinese character is read from the document to be printed.

When a kanji character is extracted from the document to be printed, the character number storage area NUM is used to update the kanji character number.
"1" is added to the value of (step B8). Then, this Kanji code is expanded into font data, but in this case, it is expanded into font data of the standard typeface (Mincho type) (step B9). Next, the character size of the font design portion is detected from this font data and set in the X size storage area CHX and the Y size storage area CHY (step B10). In this case, as shown in FIG. 6B, the character width in the X-axis direction (X size) and the character width in the Y-axis direction (Y size) of the plane coordinate system are obtained in the font design portion. Next, the cumulative character size is calculated, and the values of the X size storage area CHX and the Y size storage area CHY corresponding to the values of the cumulative X size storage area ACX and the cumulative Y size storage area ACY are accumulated (step B11). . As a result, steps B8 to B11 are executed each time a Chinese character is extracted. As a result, the number of extracted Chinese characters is stored in the character number storage area NUM, and the X in the font design portion of each Chinese character is stored in the cumulative X size storage area ACX.
The cumulative value of the size and the cumulative Y size storage area ACY are set to the cumulative value of the Y size in the font design portion of each Chinese character.

When the completion of reading the document is detected in step B14, the process proceeds to step B15 to calculate the average character size. That is, the value of the cumulative X size storage area ACX is divided by the value of the character number storage area NUM to obtain the average value of the X size, and the value of the cumulative Y size storage area ACY is divided by the value of the character number storage area NUM. Find the average size. Since the rectangular area formed by the average value of X size and the average value of Y size thus obtained may be a horizontally long or vertically long area, in the next step B16, the average value in the X direction and Y The average character size of the square is calculated by adding the average value of the direction and dividing it by "2", and the standard typeface average size storage area AV
Set to S.

In the case where the font data is developed in the standard typeface in this way, if the average size of each kanji in the font design portion is obtained, the process proceeds to the next step B17, and the similar average size is also obtained for the designated typeface. It is checked whether or not the calculation has not been completed, and this time, a designated typeface (for example, a writing style) is selected as a processing target of the average size calculation process (step B18). And
Returning to step B3, when the font data is expanded in the designated typeface by repeating the same process, the average size of each Chinese character in the font design portion is obtained and set in the designated typeface average size storage area AVA. .

FIG. 4 is a flowchart showing the document printing process. First, the reading start position of the document data is set in the reading start position storage area TOP (step C1). Next, the document capacity is set in the document capacity storage area CAP (step C2). Then, it is checked whether the designated typeface is the standard typeface (step C3). If the standard typeface Mincho typeface is designated, the process proceeds to step C6, but if another typeface is designated. Processing for changing the number of print points (steps C4 and C5) is executed.

That is, the value of the standard typeface average size storage area AVS and the value of the designated typeface average size storage area AVA are read out to obtain their ratios (step C4). Then, this ratio is multiplied by the number of print points set in the print point number storage area PPT, and the result is used as a new number of print points to update the number of points (step C5). Thereafter, as usual, the character code indicated by the value of the read start position storage area TOP is read (step C6), and this is expanded into the font data of the designated typeface (step C7). In this case, the font data is developed into a font size corresponding to the changed number of print points and printed out (step C8). Next, the value of the read start position storage area TOP is updated (step C
9) The value of the document capacity storage area CAP is updated (step C10). Then, the process returns to step C6 until it is detected in step C11 that printing of the entire document is completed.
The printing operation is performed character by character.

As described above, in this embodiment, when a typeface other than Mincho typeface is designated, the number of printing points designated in advance is changed according to the designated typeface. At that time, the number of printing points was changed based on the ratio of the average size of the font design part developed with the Mincho typeface of each kanji composing the document to the average size of the font design part developed with the specified typeface. Therefore, even if there is a variation in the size of the font design portion depending on the typeface, the printing result will be that in which the variation is eliminated. Therefore, even if a document in which a plurality of typefaces are mixed is printed with the same number of points, the impression that the character size is different as in the conventional case is eliminated, and an extremely natural printing result can be obtained.

[0018]

[Second Embodiment] A second embodiment will be described below with reference to FIG. In the first embodiment, the number of printing points is changed based on the ratio between the average size of the standard typeface and the average size of the designated typeface. However, in this example, each typeface is designed to simplify the process. Corresponding to the above, a table memory (not shown) for fixedly storing the ratio of the font design portion to the reference typeface is provided in advance, and the number of printing points is changed according to the contents of the table memory. In addition, this embodiment further uses the same typeface, for example, as shown in FIG.
As shown in (B), even if there is a variation in the size of the font design portion between characters, it is possible to obtain a print result that does not have that variation.
That is, first, similarly to the first embodiment described above, the average size calculation processing of the present embodiment is also executed according to the flowchart shown in FIG. 3, but in the present embodiment, the average size is obtained only for the designated typeface.

FIG. 5 is a flowchart showing the document printing process according to the present embodiment. The start position is set in the read start position storage area TOP (step D1), and the document capacity storage area CA is set.
The document capacity is set in P (step D2). And
The character code indicated by the value of the read start position storage area TOP is read out and set in the read character storage area CHR (step D3), and this character code is expanded into the font data of the designated typeface (step D4). The X size and Y size of the design portion of this font data are detected and set in the corresponding X size storage area CHX, Y size storage area CHY (step D5). Then, a process for determining the larger one of the X size and the Y size as the character size is performed (steps D6 to D8).

Next, the number of designated points × (average character size × character size) is calculated, and the number of points is changed by setting the calculation result as a new print point number (step D9). Therefore, if the size (character size) of the font design part of the character just read is larger than the average character size, the number of points after the change will be smaller than the specified number of points, and conversely if it is smaller than the average character size, the The number of points will be greater than the specified number of points.

Further, in this embodiment, the number of printing points is changed according to the typeface (step D10). In this case, the number of points corresponding to the typeface is changed by multiplying the number of points changed in step D9 by a fixed value such as “1.06” for the writing brush with respect to the reference typeface (for example, Mincho typeface). I do. Then, in order to read the next character, the value of the read start position storage area TOP is updated (step D12), and the document capacity is updated (step D1).
3) The process returns to step D3 until the document capacity becomes "0" and the end of printing is detected in step D14, and the above operation is repeated character by character.

As a result, in the present embodiment, it is possible to obtain a good printing result without variation in the font design portion between each typeface and between each character of the same typeface. Further, since only the average value of the designated typeface is calculated, the processing speed can be increased as compared with the first embodiment. Although the above-mentioned embodiment shows the case where the writing brush is the designated typeface, it may be a pen typeface, a pop typeface, or the like. Further, in the above-mentioned embodiment, the Mincho typeface is taken as an example of the reference typeface, but it may be a Gothic typeface or the like.

[0023]

According to the present invention, even if there is a variation in the size of the font design portion depending on the typeface, in order to eliminate the variation, the predesignated character size can be changed according to the typeface. For example, there is no impression that the number of printing points is different when printing the same document in Mincho style with the same character size as in the past and when printing with a writing brush, so multiple typefaces are mixed. Even if the document is printed, a good print result can be obtained.
