Abstract

PURPOSE:To generate many patterns with the small amount of data by decomposing a symbol pattern, etc., into constituent elements and holding them as fundamental constitution font data. CONSTITUTION:This system is provided with a means (font memory) 25 stored with the constituent elements (basic constitution font data) obtained by decomposing character pattern data and a memory (work memory for composition) 26 used to put the constituent element together. Then the character pattern data is decomposed into the fundamental constituent elements, which are stored as the fundamental constitution font data into the font memory 25. Then a character pattern generation part 24 when judging from an input code that the character pattern corresponding to the code can be composed of the fundamental constitution font data reads the fundamental constitution font data out of the font memory 25 and the character pattern is composed of the element on the work memory 26 for composition. Consequently, the capacity of the font memory 25 is reducible.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a character pattern generation method for page printers, etc., and particularly relates to a character pattern generation method that can generate a large amount of butter with a small amount of data [conventional] [Technology] Conventionally, when outputting characters and symbols to a dot-type printer or display, the glyphs and symbols are stored in a font memory, and a corresponding pattern is generated according to the input code.

For example, in the character generator in a dot-type blender,
Characters are broken down into dots, and each dot is divided into bits and stored. At this time, IC memories such as RAM and ROM are used as high-speed font memories. With this RAM, it is necessary to load the pattern every time the power is turned off, but character sets and character patterns can be easily changed, so it is often used in high-speed printers, and ROM is fixed. Since it does not require pattern loading, it is often used for displays and low-speed printers.

In such devices, in order to improve character quality, it is necessary to increase the memory capacity, and as the number of characters and symbols to be prepared increases, the memory capacity also increases.

The conventional character pattern generation method is described, for example, in "Kyoritsu Comprehensive Computer Dictionary 9, Japan 22 Back Research Institute, Hajime, Russia, Kyoritsu Publishing Co., Ltd., 1986."

[Problem to be solved by the invention]

In the above conventional technology, when preparing a font pattern for each character or symbol as data such as a dot format, as the number of character symbols to be prepared increases, the required font memory also increases in proportion to this. Put it away.

The purpose of the present invention is to improve these problems, and to develop characters that can generate many patterns with a small amount of data by decomposing symbol patterns etc. into constituent elements and holding them as basic constituent font data. The object of the present invention is to provide a pattern generation method.

[Means to solve the problem]

In order to achieve the above object, the character pattern generation method of the present invention includes constituent elements ( Means for storing (basic configuration font data) (font memory)
and a memory (composition work memory) used to synthesize the constituent elements, decompose the character pattern data into constituent elements and store them in the font memory, and synthesize the constituent elements in the composition memory. It is characterized by generating character patterns.

[Effect]

In the present invention, character pattern data is decomposed into basic constituent elements and stored in a font memory as basic constituent font data.

In addition, when the character pattern generation unit determines based on the input code that the corresponding character pattern can be obtained by synthesizing the basic constituent font data, it reads the basic constituent font data from the font memory and synthesizes it in the composition work memory. , generates a character pattern.

Therefore, the capacity of the font memory can be saved more than before, which promotes cost reduction and multifunctionalization of the device.

[Example J An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a flowchart showing a character pattern generation method in one embodiment of the present invention, and FIG. 2 is a block diagram of a character display/printing device in one embodiment of the present invention.

21st! 1, 21 is an interface, 22 is a control unit that controls the entire device, 23 is a code memory that stores input code data, 24 is a character pattern generation unit, and 25 is a ROM, which stores font data and basic configuration fonts. Font memory for storing data, 26
27 is a display/print memory; 28 is a video control unit; 29 is a printer control unit;
0 is a CRT, and 31 is a printer (RRN).

In this embodiment, a part of the font data is decomposed into basic constituent elements (such as kanji bias, stroke, frame pattern, etc.) and stored in advance in the font memory 25 as basic constituent font data.

In addition, the character pattern generation section 24 uses a computer (not shown)
The code data input from font memory 2
A character pattern is generated by synthesizing the font data stored in 5 or the basic configuration font data.

Next, the procedure for generating character patterns will be described.

As shown in FIG. 1, at the same time as storing code data such as characters inputted from a computer in the code memory 23, the character pattern generation unit 24 determines whether the pattern corresponding to the code should be obtained by synthesizing the basic configuration font data. It is determined whether or not (101°102).

As a result, if compositing is not used, the font memory 2
5 reads the font data corresponding to the code and stores the pattern in the display/print memory 27 (103
, 106), and output to the CRT 30 or PRN 31 via the video control section 28 or printer control section 29 (107).

Further, in step 102, if a pattern is obtained by synthesizing the basic constituent font data, the basic constituent font data is read out from the font memory 25 to the composition work memory 26 and synthesized (104, 105), and is stored in the display/printing memory 27. After memorizing, output <106
, 107).

Next, a specific example of synthesizing basic configuration font data will be described.

FIGS. 3 to 5 are diagrams showing examples of creating font data in an embodiment of the present invention.

In this embodiment, as shown in FIG. 3(a), the basic configuration font pattern includes the first digit "0~9", the second digit "O~9", and the frame pattern "09()". 9 mouths, △
” etc. are stored in the font memory 25.

As a result, for example, a symbol "(12
)” is input, (b)
For example, the ones place number “1” and the tens place number “2”
'' and the frame pattern "()" in the composition work memory 26 to obtain "(12)".

Further, as shown in FIG. 4(a), by storing biased data and labor data of kanji as a basic constituent font pattern in the font memory 25, these can be synthesized in the synthesis work memory 26, for example. A kanji pattern as shown in (b) can be obtained. Note that in the case of kanji, a single character is not necessarily synthesized from the combination of bias and labor.

Furthermore, as shown in FIG. 5(a), by storing kanji patterns and frame patterns in the font memory 25 and combining them, it is also possible to generate a kanji symbol with a frame as shown in FIG. 5(b). .

According to this embodiment, for example, 20 kinds of frame patterns for the digit number and the second digit number, and n kinds of frame patterns are stored in the font memory 2.
5, it is possible to synthesize 10XIO×n types of framed number patterns. Also, kanji are biased,
By laboriously decomposing or combining character patterns and frame patterns, more patterns can be obtained with a smaller amount of data.

〔Effect of the invention〕

According to the present invention, many symbols can be displayed/printed by simply preparing several types of basic configuration font data, so the memory for font data can be significantly saved.

Therefore, cost reduction and multi-functionalization of the device can be promoted.
