Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a decorative character generator, which is used, for example, in a Japanese word processor.

<Prior Art> Recently, with the widespread use of Japanese word processors, a variety of characters such as decorative characters are required for characters that can be output. Conventionally, as a method of generating this decorative character,
Various proposals have been made for a character represented in vector by approximating the contour of the character by a vector using a coordinate system.

<Problems to be Solved by the Invention> In the above-mentioned vector method, although the quality of decorative characters is good, it takes a long time to process and is also applicable to the dot pattern character generator currently used in OA equipment. Can not.

<Means for Solving Problems> The present invention is a decorative character generator that sequentially decorates a character formed by a dot matrix in a dot unit at a fixed timing to generate a decorative character. An original dot pattern memory for storing the dot pattern of the read character, an ambient condition reading means for reading the dots around each dot forming the dot pattern of the character, and a comparison dot pattern are provided in advance. Compare the dot pattern and the dot arrangement pattern around each dot read by the surrounding condition reading means,
Decoration processing means for arranging dots at locations corresponding to the respective dots of the original dot pattern memory based on the result of this comparison to decorate characters in dot units; and decorative character pattern means for storing the decorated character pattern. It is a decorative character generating device characterized by comprising.

<Embodiment> FIG. 1 shows a basic configuration of a decorative character generator. The character font memory 1 stores a dot matrix character font to be decorated. Original dot pattern memory 2
Temporarily stores the original dot pattern of the character font designated by the character designation signal s in the character font memory 1. The peripheral situation reading unit 3 reads the situation of the presence / absence of dots around each dot in the original dot pattern stored in the original dot pattern memory 2. Decoration part 4
On the basis of the information indicating the situation around the dot read by the peripheral situation reading unit 3, the dot is arranged at a position corresponding to the dot on the decorative character pattern memory 5, and the decoration process is performed in dot units. The timing generation section 6 gives a timing signal to each of the above-mentioned sections.

FIG. 2 shows the configuration of the peripheral condition reading unit 3. Reference numeral 31 is a shift register for storing four rows of the original dot pattern, and reference numeral 32 is four serial-in / parallel-out 4-bit shift registers. Original dot pattern memory 2
The original dot patterns are sequentially input from the shift register 31 to the shift register 31, and the bit state of A to G when the bit data corresponding to the dot of this original dot pattern reaches the position C of the shift register 32 is the original dot pattern. It matches with the presence / absence of dots around the dot. In this way, the peripheral situation reading section 3 can read the situation around the dot.

Hereinafter, in this embodiment, the procedure of processing for three-dimensional decoration of a character (making a character three-dimensional) will be described. In the three-dimensional decoration of this character, the three-dimensional character pattern shown in FIG. 4 is obtained from the character pattern shown in FIG.

FIG. 3 shows a part of the 32 × 32 dot pattern of the character “A”. Now, assuming that the dot (A) of this character pattern is the dot to be processed, the peripheral condition reading unit 3 reads the status of the presence / absence of dots around this dot (A). At this time, the dot pattern corresponding to the information read to the shift register 32 is, as shown in FIG. 5, the bits A, B, F, and G of the shift register 32 being "0" and the portion corresponding to this bit. There is no dot in the shift register
The 32 bits C, D, and E are "1", and there is a dot in the portion corresponding to this bit. The shaded circles correspond to dots (a) and correspond to the bit C of the shift register 32. Also,
Circles without hatching correspond to two dots to the right of the dot (a) and correspond to bits D and E of the shift register 32. Information indicating the situation around the dot (a) is sent to the decoration unit 4. The decoration unit 4 first arranges the dots (a) in the decoration character pattern memory 5. At this time, in the decorative character pattern memory 5, as shown in FIG. 6, dots (a) are written at the positions of the shaded circles.

Next, the decoration section 4 determines the three-dimensional side surface intermediate section a of the character pattern shown in FIG.
And dots are formed on the three-dimensional side end portion b. FIG. 7 shows a logic circuit for the process of forming dots in the intermediate portion a of the three-dimensional side surface. Inputs A, B, F, D, E, G are bit A,
It corresponds to the states of B, F, D, E, and G, respectively. 4 shown in FIG.
The two patterns are comparative patterns provided by the decorative portion 4,
FIG. 7 shows a pattern in which the logic circuit outputs "0" to a. However, this pattern is bit E of the shift register 32,
This is the case except when there is a dot for G.
Comparing the pattern of FIG. 8 with the read dot pattern shown in FIG. 5, the pattern of FIG. 5 does not match any of the four patterns of FIG. 8, so the logic circuit of FIG. Output "1" to a. Then, the decorative character pattern memory 5 shown in FIG.
The two dots forming the are written. By this processing, 2 of the three-dimensional side surface intermediate portion of the three-dimensional pattern shown in FIG.
Individual dots a are formed.

FIG. 9 shows a logic circuit for arranging dots at the three-dimensional side end portion b in the decorative portion 4, and the inputs D, F, E, and G are in the states of the bits D, F, E, and G of the shift register 32, respectively. Correspond. The pattern shown in FIG. 10 is a comparison pattern provided in the decoration portion 4, and is a pattern in which the logic circuit of FIG. 9 outputs "0" to b. However, this pattern is a shift register 32
This is the case except when there is a dot for both bits E and G of. Comparing the pattern of FIG. 10 with the read dot pattern of FIG. 5, the pattern of FIG.
Since it does not match the pattern of FIG. 10, the logic circuit of FIG. 9 outputs "1" to b. Then, in the decorative character pattern memory 5 shown in FIG. 6, according to a predetermined processing procedure,
After the dots (a) and the solid side surface intermediate portion a, the dots forming the solid side surface end portion b are written. By this processing, the dots b at the three-dimensional side end portion of the three-dimensional pattern shown in FIG. 4 are formed.

Similarly, for each dot following the dot (a) of the original dot pattern, the formation processing of the solid side surface intermediate portion or the solid side surface end portion is performed depending on the presence or absence of surrounding dots.
Regarding the dot (a) of the original dot pattern in Fig. 3,
As shown in FIG. 4, dots are not formed in the three-dimensional side surface intermediate portion c, but dots are formed in the three-dimensional side surface end portion d.

FIG. 11 shows a part of the 64 × 64 dot pattern of the character “A”. A character pattern obtained by three-dimensionally decorating this character pattern is shown in FIG. 12, and a dot e decorated with respect to the dot (b) is formed. (However, in this case, the number of dots in the middle portion of the three-dimensional side surface is one more than that in the above-described embodiment.) As described above, in the present invention, decoration is performed regardless of the size of the dot pattern to be processed in principle. be able to. FIG. 13 shows an example in which the character “A” is three-dimensionally decorated and printed.

In the present invention, since the decoration is performed in dot units, if the decoration is sequentially applied only to the printed portion and the data is sent to the printer, the three-dimensionally decorated characters are sequentially printed as shown in FIG. .

Although the three-dimensional decoration has been described in this embodiment,
It goes without saying that various other decorations are possible by changing the logic of the decoration unit 4.

<Effect> As described above, according to the present invention, a character forming device for generating a decorative character by sequentially decorating a character formed by a dot matrix in a dot unit at a fixed timing, and comprising a character font memory An original dot pattern memory for storing the dot pattern of the read character, an ambient condition reading means for reading the dots around each dot forming the dot pattern of the character, and a comparison dot pattern are provided in advance. The dot pattern for use and the dot arrangement pattern around each dot read by the surrounding condition reading means are compared, and the dot is arranged at a position corresponding to each dot of the original dot pattern memory based on the comparison result. Decorative processing means for decorating characters in dot units and a decorative character pattern hand for storing decorated character patterns Since it has steps, not only is it possible to add three-dimensional decorations with diagonal dots,
Since a comparison pattern is provided in advance and the comparison pattern is compared with the situation of the presence / absence of dots around each dot read by the surrounding situation reading means, a plurality of types of decoration can be provided only by changing the comparison pattern. It becomes possible. In addition, the processing speed can be increased as compared with the conventional decoration of a character represented by a vector.

Further, since the decoration is performed in dot units, it is possible to perform the decoration regardless of the size of the original dot pattern. Furthermore, since the decoration is done in dot units, it is only necessary to decorate only the print portion and send the data to the printer in sequence when printing with the printer. Therefore, the buffer capacity can be reduced and printing and decoration processing can be performed in parallel. It is possible to carry out the processing with the advantage that the processing efficiency is high.
