Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character signal generation device used in printing devices or display devices such as computer copying machines, word processors: manual phototyping machines, etc.

[Zhao point that the prior art and invention are trying to solve] Character information I
In printing based on 41, one character or a symbol used with a character is kept, and these characters are combined to form a character string (line) to form a page.
There are two main ways to hold characters. One type is a cast product called movable type, and the other type is called deprinted type, in which a character image is stored in the form of a print on a flat master plate as seen in optical technology, or a record of an information signal as seen in computer technology. It is possible to do this without the need for a device to generate the restoration.

When creating character strings (lines), in the case of printed text,
The position of adjacent characters can be determined physically by simply arranging the type cast to the width of the characters (body set). This is also the case with the nogai-kai with a kuna-khan shown in Figure 1.

-1 In the case of non-printing, the damage of the character is determined numerically.

Since this is a method of controlling according to this, it is necessary to specify the character width required for character generation and the character width (2 day set) related to the character position in the character string. The font size that represents this font size series is called the body size.

For phototypesetting, in order to avoid troublesome control systems, the frame in which all character images are stored is limited, and the body size is set such that body size does not exceed body size, as shown in Figure 2. , in print, the letter W has a larger body cent than the letter M, but in non-print type, it has the same body set as the letter M.

[Generally, the body cent of the printed letter M is the body size Pc
j' is approximately equal to 1, and the body set d of the printed letter W is 1.2 times that of the printed letter M.) As shown in Figure 3, the body set of the printed letter W is approximately 1.2 times that of the printed letter M. For Vti, the italic letter W is
Furthermore, the character image becomes insufficient in width.

For this reason, at present, we are trying to balance the overall fonts for European typesetting (a set of characters in the same typeface and size required for typesetting work) and either create an overall smaller design or, as shown in Figure 1 By making the lines of ``lower'' and ``■'' higher, we deepen the knowledge of ``■'', as shown in Figure 4.
Efforts have been made to design the letters larger, but the body cent of the letter W is the same as the letter M, so the uppercase letter W ke M
It feels small compared to ``X'' and ``X'', and the lowercase letters have large exhide, giving it the beauty and strength that was once seen in print.

The disadvantage is that visibility is lost.

ti phototypesetting devices have the function of flattening, but if you simply flatten enlarge, the thickness of the line of the characters will change, resulting in a different character image, so if you want to emphasize the balance within the font, use this method. The problem was that it could not be used.

The above is a similar problem not only in printing devices but also in display devices.

Therefore, the present invention focuses on the property of deprinting that can be enlarged/reduced by connecting an additional mechanism to the front stage of the character generator of the conventional system. In a series of the same body size stored in The aim is to realize a device that enables this at a low cost.

[Means for solving problems]

Fig. 5 is an explanatory diagram of the principle of the present invention, and the figures (,) are character images stored in a known character signal generation device, the body size of which has been reduced so that the maximum body cent in the font is within the size m. It has a design of n.

That is, for a font that is stored in a character signal generator with a body size m and has characters with body cents exceeding the body size mf, the entire font is reduced so that the maximum body cent Vi falls within the body size m. Te, Akira Desai/l: Body set within m! This is a state in which a character image with body size n is stored.

(b) The figure shows the character image shown in Figure 81 as m/
Character image output at n times magnification, output size m-φ, body size m1 body set intended by design)
It expresses that m' am/n)m is obtained.

The value of m/n above is the magnification of the Fumento characteristic.

The present invention is based on the above-mentioned principle, and an embodiment thereof will be explained as follows. [Embodiment] Fig. 6 shows an embodiment of the present invention. I will explain.

Now, as control data, a font that specifies all the fonts from various fonts (referring to a set of characters with the same font and the same character size) of the Roman character family stored in the character image memory decoration (not shown). There is a difference between the control data f and the character output size control data N that instructs the output size of the font.The font control data f is used as input data for the font magnification control mechanism 100 and the character signal generation device 300, and is used to control the font magnification. Mechanism 10
When G receives the input data, it sends the specified family's font special number magnification m/nf to the font output size control mechanism 200. p1 Characters, etc. generator @ 300 receives the input data and performs all font selections. .

Then, the font output size control mechanism 200 controls the magnification m
/n and character output size control data N are stored, and when either one of the data is input, M = N -
”/n character output size control data all character signals etc. Send to device #: 300.

Then, the character signal generation device 300 generates characters with the output size of the character output size control data M for the font of the specified family, so that the result shown in FIG. 5 is obtained.

For convenience of explanation, the explanation has been given using English characters as an example, but the present invention is not limited to English characters. Furthermore, although an embodiment in the horizontal direction has been shown, the storage method for the vertical character image is not particularly limited.

Also, the font control data f is set to a specific character code P.

Is it alright? It may be replaced with a specific character code in a fixed font, or the font control data f may be divided into a stored character size instruction and a 14-font instruction.

〔Effect of the invention〕

The effects of the present invention are listed as follows: (1) All font outputs for character families designed with a body set larger than the body size of the letters W, 疯, の, 75, etc. in English letters. It was Noh.

(2) 1 in fractions as well. Similarly, wide output was possible.

(3) A thick rectangle C that you want to express beyond the body size
Enso circle, rectangle, etc.) can be output larger than the surrounding font even if the surrounding font size remains the same.

(4) Large symbols used in mathematical and chemical formulas can be output with only a fraction of the surrounding font size.
