Abstract

PURPOSE:To easily obtain desired font data at high speed by composing the font data generating device of a device stored with lateral writing font data, a device stored with longitudinal writing font data, and a means which controls and writes obtained font data. CONSTITUTION:A control means 102A interprets an indication from application software 101 and a selecting means 102B take font data on matching characters out of the storage device 103 according to the given character code and a longitudinal/lateral decision result and passes the font data to a control means 102A. The control means 102A returns the obtained font data to the application software 101. Consequently, when the font data is obtained, the application software only sends the character code and longitudinal/lateral decision indication to easily obtain desired font data fast.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a font data generation device configured to easily acquire font data.

[Prior Art] In order to output vertically written characters in a conventional Japanese word processor, etc., as shown in FIG. Take out the
In order to obtain vertical writing font data from the font data, the application software 401 determines whether it is possible to convert the font data into vertical writing font data by rotating the font data by 90 degrees (counterclockwise to the left) (3401C). If it is not possible, vertical writing font data is generated by some means (S401E).

[Problem to be solved by the invention] However, in the above-mentioned conventional technology, when converting horizontally written font data to vertically written font data, there are some characters for which the correct font data cannot be obtained by simply rotating the font data by 90 degrees. Since the correction is performed on the application software side, there is a problem in that the configuration of the application software becomes complicated. Another problem was that the conversion was performed using software, so the processing time was slow.

SUMMARY OF THE INVENTION In view of the conventional problems, it is an object of the present invention to provide an environment in which application software does not require conversion to vertical font data, and at the same time to reduce processing time.

[Means for Solving the Problems] A font data generation device of the present invention includes a device for storing horizontal writing font data, a device for storing vertical writing font data, and retrieving font data from any of the storage devices. and means for controlling and reading the obtained font data.

[Example] FIG. 1 shows an example of the present invention. The control means 102A interprets the instruction from the application software 101, and the selection means 102B extracts the font data of the matching character from the storage device 103 based on the given character code and vertical/horizontal distinction and passes it to the control means 102A. 102A transfers the obtained font data to application software 10.
Return to 1.

However, if the instruction from the application software 101 is vertical writing and the obtained font data is horizontal writing font data, the control means 102A rotates the obtained font data by 90 degrees and then prints the obtained font. The data is returned to the application software 101.

FIG. 2(A) is a configuration diagram of the embodiment. The application software 101 instructs the required character code and the distinction between horizontal writing and vertical writing (5IOIA), and the arithmetic unit 102 that receives the instruction selects either the horizontal writing font data area 103A or the vertical writing font data area 103B of the storage device 103. After extracting the font data from and adding the necessary processing, the font data is transferred to the application software 101.
In response, the application software 101 outputs the font data (SIOIB).

The logic of the arithmetic unit 102 is shown in FIG. 2(B).The arithmetic unit 102 is started by being given two data: a character code and a distinction between vertical and horizontal directions.

First, determine whether vertical writing is specified (3201)
, if vertical writing is not specified (in case of No), the storage device 10
The font data of the character indicated by the given character code is read from the horizontal writing font data area 103A in 3 (3202) and the process ends. If vertical writing is specified (
If YES), the font data of the given character code is stored in the vertical font data area 1 in the storage device 103.
Determine whether it exists in 03B (3203),
If the font data exists, the font data of the character indicated by the given character code is read from the vertical font data area 103B in the storage device 103 (S204).
finish. If it does not exist, the font data of the character indicated by the given character code is read from the horizontal writing font data area 103A in the storage device 103 (S20
5) Rotate the font data 90 degrees to the left (counterclockwise) and end 5206).

Here, the necessity of vertical writing font data is shown using Figure 3. Figure 3 (A) is an example of a horizontal writing font;
1A, 305A are parentheses, 302A is normal kana characters, 3
03A represents a small kana character, 304A represents a period, and 306A represents an underline. 306A can also be displayed in combination with other characters. Write this string vertically −
Figure 3 (B) shows each character rotated 90 degrees to the left (counterclockwise) in order to make the character string ``vertical''. (C), as can be seen by comparing Figure 3 (B) and Figure 3 (C), if the horizontal font is simply rotated 90 degrees to the left (counterclockwise), it will not be normal kana characters. cannot be used in vertical writing. Therefore, as shown in the above embodiment, it is important to generate vertical writing font data.

[Effects of the Invention] As described above, according to the present invention, when obtaining font data, application software can easily and quickly obtain desired font data by simply instructing the character code and the distinction between vertical and horizontal directions. I can do it. Furthermore, by providing a printer with a mechanism similar to that of the present invention, it is possible to output easily and at high speed.
