Abstract

PURPOSE:To decide the character pitches at a high speed and with the suitable balance by deciding the distance between characters so that the total electrostatic capacity between elements corresponding to adjacent characters is equal with all arrayed characters. CONSTITUTION:For instance, three characters 'KOT' are arrayed within a limited area 1. In this case, each character is divided horizontally into five pieces, for example, to calculate the electrostatic capacity of each of elements corresponding in the horizontal direction of the adjacent characters, i.e., five elements C0-C4 and C0'-C4' respectively. Then the distance between both characters is decided so as to satisfy C0+C1+C2+C3+C4=C0'+C1'+C2'+-C3'+ C4'. For this purpose, 1/(distance) is decided for each element and the distance between characters is decided so that the coincidence is secured among the total value of the electrostatic capacity of those elements. In such a way, the character pitches can be decided with good balance to attain a beautiful array of characters.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for determining the distance between one character, and in particular to a method for determining the distance between characters, and in particular to a method for determining the distance between characters, and in particular, a method for determining the distance between characters using CAD (Computer Aided Design
n)).

[Purchase of invention]

CAD (computer-aided design) for circuit analysis, layout/wiring 1 diagnosis, numerical control work, etc. is the most advanced field. In other fields as well, as there is a strong demand for lower product prices and shorter delivery times,
CAD is being considered for optimal design that comprehensively considers performance and other factors.

CAD block diagrams have conventionally been performed in the order shown in FIG. First, by inputting product specifications, a description of the specifications and standards are created, and constraints are stored (step 101). Next, information regarding the product is accumulated (step 102). Next, a product model is created based on the information and various values of the parameter variables are tried (step 103). Perform physical measurements,
Maintenance.

Evaluate one alternative plan considering reliability (Step 10)
4). Next, perform analysis and testing (step 105).
, evaluate (step 106). If the evaluation results are satisfactory, the design information is converted into manufacturing information (step 107). The process moves to the manufacturing process (step 108). If the evaluation results are unsatisfactory, optimization is performed (step 109), and feedback is provided to each stage of product model creation (103), alternative plan evaluation (104), and analysis/testing (105) to optimize the results. Replace it with the original information and repeat the execution.

By the way, CAD conversion of printed characters for word processors, typewriters, etc. is being actively carried out. Character generator (ROM or RAM) for word processors, etc.
In order to make the dot character pattern stored in the alphanumeric character (
English characters, kana characters.

7x9 dots are sufficient for numbers (numbers, etc.), but for kanji, 24x24, 36x36, etc. Alternatively, a dot such as 48x48 is required. Various character types using such dot patterns are designed using CAD. In this way, CAD conversion of character types is generally performed, but there is little interest in CAD conversion of character arrays, probably because this is the domain of designers' sensibilities.

The printed characters and character patterns of conventional typewriters, word processors, etc. all have a fixed size, and each character is determined to make maximum use of the character frame.

In other words, as shown in Figure 2, the size and position of kanji characters such as ``now'', ``kuni'', ``1 day'', and ``quantity'' are determined relative to one character frame, and in this case, the center distance between the characters is fixed. It is designed to be arranged beautifully. However, regarding the spacing (pitch) between letters, if the distance between the frames is constant, the spacing between simple letters or letters with protrusions will feel wide, and complex letters or letters with protrusions will feel wider. The spacing between letters without parts seems narrow.

Furthermore, when the spacing between Kanji characters and the spacing between Kana and English letters are set to the same dimension, the overall arrangement of the characters feels strange. This is because the dimensions of kanji and kana are extremely different, and it can be seen that the beauty of a sentence is also related to the spacing between letters. To solve this problem, instead of making the spacing between letters the same, it is necessary to create a different spacing for each character depending on the complexity of the character, in other words, use proportional spacing.

Strictly speaking, the gap between irregularly shaped characters is
It needs to be constant. But traditionally.

Since this kind of troublesome work could not be done, the spacing was kept constant except when the letters were arranged partially in flat type.

[Purpose of the invention]

The purpose of the present invention is to solve such problems, and when printed characters or character patterns are arranged according to a general design concept, the spacing between each character appears to be lined up beautifully even when compared to the human sense, and from the overall perspective. To provide a method for determining a distance between characters that can be calculated using CAD to achieve a well-balanced size.

[Summary of the invention]

In order to achieve the above object, the method for determining the distance between characters according to the present invention provides a method for determining the distance between characters when the distance between a plurality of characters arranged horizontally or vertically and containing a mixture of kanji, kana, etc. is calculated using a CAD program. The amount of capacitance or approximation between corresponding constituent elements of a character is calculated for all elements in the vertical or horizontal direction, the sum of the calculated values is determined, and the sum of the amount of capacitance or approximation for each character interval is calculated. The feature is that the distance between each character is determined so that the value is equal between all characters arranged.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram of a method for determining distance between characters, showing an embodiment of the present invention.

In FIG. 1, - as an example, rKOT is
The case of arranging the three characters J will be described below.

In the present invention, when determining the distance between each character,
It is determined so that the sum of capacitances between corresponding constituent elements of adjacent characters is constant.

Taking rKOTJ as an example, if each character is divided horizontally into 5 parts, the electrostatic capacity of each element corresponding to the horizontal direction of the adjacent character, that is, rKJ and "0" for each of the 5 elements. ” between Go””C4 and “Q”
CO'-C4' between and rTJ is calculated, and c, +C1+
c2 +Ca +c4 =Go'+Ct' +c
2'+c3'+c4' The character spacing for both is determined.

Now, when calculating the capacitance between corresponding constituent elements of adjacent characters, C is the capacitance and A is the opposing area of the elements (dl, Q
The following equation holds, where is the distance between the elements and ε is the dielectric constant.

C=0.0885tA/12(PF)...
・(1) In the above formula (1), ε=1. Assuming A=1, C=0.0885/Q, and the capacitance C
It can be seen that is inversely proportional to the distance 1lIIQ. Therefore, the capacitance CO~C4 between corresponding elements of adjacent characters
In order to determine the spacing between each character so that the summed capacitance values are equal, find 1/Ω for each element and set the distance between the characters so that their total value Σ1/Q is equal. Just determine the distance. First, assuming that the total value Σl/Q between rKJ and "0" is m, and the total value Σl/12 between "0" and "T" is n, (mf-n),
After shifting the position of "○" to one side, the distance between the corresponding elements is measured again, and the position of "0" is repeatedly shifted so that m=n. This makes it possible to create a more balanced arrangement according to human senses.

When explaining capacitance below, it is safe to assume that mutual elements are parallel.

Explain using dotted characters.

In general, human senses tend to perceive things that follow the laws of nature as beautiful, such as the golden ratio. When alphabetic characters are arranged in a line, it does not feel unnatural even if the distances between each character are all the same, but when a mixture of kanji and kana are arranged in a line, printed letters, etc. Characters are designed so that they do not look unnatural even if they are lined up with a constant distance between them, but if all the distances between characters are the same for graphic characters and other characters that are not intended for this purpose, it will look extremely unnatural. For example, FIG. 5 shows the case of horizontal writing, and FIG. 6 shows the case of vertical writing, both of which have the same distance between adjacent characters. The center line is the center line of each letter. As is clear from this, the distance between kanji characters does not feel wide, but the distance between kana characters does feel wide. 5 and 6. According to the invention, the total capacitance between corresponding elements of adjacent characters is equal, i.e. for the distance between corresponding elements of adjacent characters l/( After determining the distance between the characters and arranging them so that the total value for all horizontal or vertical elements is equal for all the arranged characters, the distance between the characters is determined and arranged. As a result of verification by experts, it was determined that the arrangement was aesthetically pleasing. but,
The inventors further calculated the distance between corresponding elements of adjacent characters by setting m of 1/(distance) m to an arbitrary value, and found that 1/(distance) ~ 1 bar distance) 2
In the ceremony, all of these were judged by experts to be perceived as beautiful. And within these ranges,
When several experts were asked to select the formula that felt most beautiful, they found that 1/(distance) 1.3 resulted in the most beautiful letter spacing. In the following example, the capacitance between elements will be calculated using the formula 1/(distance).

FIG. 3 is an explanatory diagram of how to take the distance between characters for the kanji character "按".

In FIG. 3, when a plurality of characters such as kanji or kana are arranged in horizontal writing, a method for determining the distance on both sides of the 50×50 element kanji ``按'' will be described. In this case as well, the capacitance between corresponding elements is measured in the same manner as described in FIG. 1, and the distance is determined so that the total capacitance value of all elements is equal to each character interval. Since there are 50 elements in the vertical direction, 50 calculations are performed on one side and the calculations are totaled. In the figure, C5, C12, C27, C46, and C5

Only C45' is shown and the rest are omitted.

These capacitances CO~cso, co'~C50' are
Since it is inversely proportional to the distance between elements, 1/R1O ~
1/P)so+1/QO' to 1/R50' may be calculated and these values may be summed.

Although Figure 3 describes the case of kanji, when creating a single sentence, as shown in Figure 5 or 6, characters smaller in size than kanji such as kana and English letters are arranged. However, when adjacent characters are a kanji and a kana, the number of corresponding elements is insufficient because the size of the kana is smaller than that of the kanji. In addition, when kana and kana are adjacent, the number of corresponding elements is the same, but because there are fewer elements and the number of times the distance is calculated is small, the capacitance between other characters is set to the same value. If you take the character spacing,
The interval tends to become extremely small. Therefore, one idea of the present invention is to provide a virtual element 2 to compensate for the missing element within a certain distance Q from the most protruding element in the horizontal direction of the character, as shown in FIG. Assuming that the capacitance is always made up of constant elements, we decided to calculate the distance between the assumed elements to find the capacitance. As a result, it is now possible to obtain appropriate character spacing, both when kanji and kana are adjacent, and when kana and kana are adjacent, making it possible to obtain a character arrangement that looks aesthetically pleasing.

FIG. 4 is a CAD processing flowchart of a method for determining distance between characters, showing an embodiment of the present invention.

First, the I/Q between corresponding dots of adjacent characters (fl is the distance between elements) is calculated for all characters (step 201). Next, for each character, calculate 1 for each side.
The sum of the values of /Q is calculated (step 202). Then, it is determined whether the calculated total values Σ1/Q are equal for all characters (step 203), and if they are equal, the process ends. If they are not equal, the position of one character is shifted so that Σ1/Q becomes equal for all characters. Next, the process returns to step 201 at the shifted position, and 1/Ω between corresponding elements of adjacent characters is calculated again.

In this way, for all characters the total value Σ1/Q
Repeat this operation until they are equal. in this way,,
By processing the invention in CAD.

No matter how huge the number of characters are arranged, or how many elements make up the character pattern.

Accurate inter-character distances can be calculated for each character without requiring much time or manpower.

〔Effect of the invention〕

As explained above, according to the present invention, when determining the distance between characters by CAD, the total capacitance between corresponding elements of adjacent characters is made equal for all arranged characters. By determining the distances, it is possible to determine the pitches of all characters at an extremely high speed, and it is also possible to determine the distance between characters in an arrangement that looks aesthetically beautiful to humans. Therefore, by utilizing this method as a means for determining character spacing in a character typesetting device using a CAD system, a computer typesetting device, a word processor, etc., it is possible to realize various devices with higher efficiency than ever before.
