Description

Description: TECHNICAL FIELD The present invention relates to a character output device that outputs output pattern data corresponding to character data to be output.

[Summary of the Invention] A printing font data output device according to the present invention, when creating an outline font from a dot font and performing printing, simultaneously stores the created outline font temporarily in a RAM, When printing the same character, the outline font stored in the RAM is output so that the outline font once created can be reused.

[Prior Art] In a conventional Japanese word processor, by using an outline font in addition to printing with a normal dot font, enlarged characters can be printed beautifully or printed with a brush or the like. There are things that are. That is, in such a Japanese word processor, when a character code of a character to be printed is given, a dot font corresponding to the character code is generated by a character generator, and an outline font is created from the generated dot font. Then, printing is performed using the created outline font.

[Problems to be Solved by the Invention] As described above, in a conventional character output device such as a Japanese processor, output using an outline font is performed in order to perform output such as printing using an outline font. Must be specified in correspondence with the character. In particular, characters for which enlargement is specified are often scattered in the page to be printed, but enlargement and output using an outline font must be specified for each of the scattered characters to be enlarged. Was very troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to immediately output output pattern data corresponding to character data to be output.

[Means for Solving the Problems] The means of the present invention are as follows.

Output pattern storage means for storing output pattern data for character data for which special processing is specified; first determination means for determining whether character data to be output is character data for which special processing is specified; When the first determination unit determines that the character data is not the character data for which the special processing has been specified, the first output control unit generates and outputs output pattern data corresponding to the character data; If the determination means determines that the character data is character data for which special processing has been designated, it is further determined whether or not output pattern data corresponding to the character data is stored in the output pattern storage means. When it is determined that the corresponding output pattern data is not stored in the second determining means, the character data is On the other hand, it generates output pattern data for which special processing has been designated, stores the generated output pattern data in the output pattern storage means, and outputs the generated output pattern data. A second output control means for reading out and outputting the stored output pattern data when the means determines that the corresponding output pattern data is stored.

[Operation] The operation of the means of the present invention is as follows.

Output pattern storage means for storing output pattern data for character data for which special processing is specified; first determination means for determining whether character data to be output is character data for which special processing is specified; When the first determination unit determines that the character data is not the character data for which the special processing has been specified, the first output control unit generates and outputs output pattern data corresponding to the character data; If the determination means determines that the character data is character data for which special processing has been designated, it is further determined whether or not output pattern data corresponding to the character data is stored in the output pattern storage means. When it is determined that the corresponding output pattern data is not stored in the second determining means, the character data is On the other hand, it generates output pattern data for which special processing has been designated, stores the generated output pattern data in the output pattern storage means, and outputs the generated output pattern data. If the output means determines that the corresponding output pattern data is stored, the second output control means reads and outputs the stored output pattern data. If the character data for which processing has been specified, and the output pattern data for that character data is stored,
The stored output pattern data can be output immediately, and if the character data has no special processing designation, the corresponding output pattern data can be generated and output immediately.

Embodiment An embodiment will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a diagram showing the configuration of a printing font data output device according to an embodiment. Reference numeral 11 denotes a document memory for storing document data to be printed created by a document creation function of a Japanese word processor. Reference numeral 12 denotes a print data creation device that reads out document data to be printed by the printing device 13 from the document memory 11 and analyzes each character code constituting the document data and modification information such as enlargement designation corresponding to the character code. is there.

Reference numeral 14 indicates a character to be output by a normal dot font or a character to be output by an outline font by judging a character size or the like from a character code and modification information given from the print data creation device 12. This is a font data control device that makes a determination and performs a font output process or an outline font output process as described below according to the result. The font data control device 14 outputs print pattern data composed of dot font data or outline font data to the print data creation device 12,
Creates print data using the print pattern data and supplies the print data to the printing device 13.

Reference numeral 15 denotes a storage device including a RAM for storing outline font data generated by the outline data generation device 16 during the outline font output processing. Reference numeral 17 denotes a character generator (CG) ROM that stores dot font data corresponding to character codes.

Hereinafter, the operation of the printing font data output device having the above configuration, particularly the operation of the font data control device 14 which is a characteristic part of the present invention, will be described with reference to the flowchart of FIG.

That is, when the character code data and the modification information are supplied from the print data creation device 12, the font data control device 14 reads them (step S1) and outputs the characters to be output in a normal dot font or the outline font. It is determined whether the character should be changed, that is, whether it is necessary to convert the character to an outline font (step S2).

If the character is to be output using a normal dot font, that is, if it is not necessary to convert it to an outline font, font output processing is performed (step S
3). That is, it reads out the dot font data corresponding to the character code data from the CGROM 17 and outputs it to the print data creation device 12 as print pattern data.

If the character is to be output using an outline font, that is, if conversion to an outline font is necessary, outline font output processing is performed (step S4).

This outline font output process is shown in more detail in the flowchart of FIG. That is, the outline font data stored in the storage device 15 is searched to check whether or not the outline font data corresponding to the read character code data exists in the storage device 15 (step S41). If the outline font data exists in the storage device 15 (step S42), the outline font data is read from the storage device 15 (step S4).
3) It is developed into dot pattern data for printing and output to the print data creating device 12 as print pattern data (step S44).

If there is no corresponding outline font data in the storage device 15 (step S42), the CGROM 17
Then, the dot font data corresponding to the character code data is read out and supplied to the outline data generator 16 (step S45). When the outline font data created by the outline data generator 16 is output (step S46), the outline font data is developed into dot pattern data for printing, and the above-described print data creation device is used as print pattern data. Output to 12 (step S44).

Subsequently, a process of writing the output outline font data to the storage device 15 is performed. First, it is determined whether the output outline font data is data read from the storage device 15 or data supplied from the outline data generation device 16 (step S4).
7). Here, if the output outline font data has been read from the storage device 15, that is, if the output outline font data exists in the storage device 15, the outline font data is deleted (step S48). ). Next, a storage capacity check is performed to determine whether outline font data can be added to the storage device 15 (step S49). If there is a storage capacity, the output outline font data is stored in the storage device 15.
Is additionally written at the end of (step S50). If the storage capacity is full, the first outline font data, that is, the oldest outline font data is deleted (step S51), and the output outline font data is additionally written to the end of the storage device 15 (step S50). ). When the outline font data is deleted, all the outline font data after the deleted outline font data are shifted so as to fill the area vacated by the deletion,
The area vacated by the deletion comes to the end of the storage device 15.

That is, the output outline font data is written in the storage device 15. At this time, when the outline font data is output from the storage device 15, the outline font data is temporarily deleted. Next, the currently output outline font data is added to the end of the outline font data stored in the storage device 15. When adding this outline font data,
When the storage capacity of the storage device 15 is not enough to be added, the oldest outline font data is deleted, and then the current outline font data is added. In other words, the used outline font data is always added to the end of the storage device 15, and when the storage capacity becomes full and the outline font data must be deleted, the outline font data is deleted from the head data, thereby deleting the storage device 15. Will always hold the latest outline font data.

FIG. 4 is a diagram showing an outline of data stored in the storage device 15. In this case, in order to increase the storage efficiency, character code data 152 and data size information 153 are continuously stored before the created outline font data 151.

Here, whether outline font data of a certain character code exists or not is checked from the beginning of the storage device 15 with the character code data 152, and if they do not match, the data size information 153 is added to the current address. When the given data size is added, the address of the character code data of the next character is indicated. Therefore, the operation can be repeated by repeating the operation until the current address matches the leading address 155 of the empty area 154.

When the outline font data is deleted, the address of the next character code data is calculated from the data size of the outline font data designated for deletion, and the start address of the free space 154 is calculated from the address of the next character code data. This can be done by shifting the data up to 155 by the data size of the outline font data designated for deletion.

Thus, at the same time as generating outline font data from dot font data and printing,
Temporarily transfer the created outline font data
The outline font data stored in the RAM is output the next time the same character is printed in the RAM, so that the outline font data created once can be reused. .

[Effects of the Invention] According to the present invention, when character data to be output is character data for which special processing is specified, and when output pattern data corresponding to the character data is not stored, , Output pattern data corresponding to the character data can be generated and output. In addition, by storing the generated output pattern data, even if the character data to be output later is character data for which special processing is specified, the character data is output first. Is generated, and if the character data is already stored, it can be output immediately using the output pattern data stored corresponding to the character data. Further, if the character data does not have special processing designation, output pattern data corresponding to the character data can be immediately generated and output.
