DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An external character processing apparatus according to an embodiment of the present invention will be described below with reference to the drawings. First, an external character code system (hereinafter referred to as a first external character code system) applied in this external character processing device will be described.

FIG. 1 is a diagram showing an example of a code string of the first external character code system in the embodiment. In FIG. 1, “75214142790B” in a 6-byte hexadecimal format is used in the first external character code system to represent the external character “circle stock”. The first 4 bytes are the identifier, the first 2 of them
The byte is an external character identification code that means an external character. This external character identification code is a conventionally unused code. Also,
The 3rd and 4th bytes represent the group code, and the 5th and 6th bytes are the external character specifying code uniquely corresponding to each external character.

FIG. 2 is a block diagram of the external character processing device in the embodiment of the present invention. The configuration of the external character processing device will be described with reference to FIG. In FIG. 2, reference numeral 1 denotes an external character registration unit that registers and registers an external character font for each external character code string of the first code system. More specifically, the external character registration unit 1 checks a font generation unit 1a for generating a font of an external character according to an operator's operation and whether the code string designated by the operator corresponding to the font is an unused code, The external character code string determining unit 1b determines an external character code string, and the file generating unit 1c generates a file corresponding to a group. Note that the external character code string determination may be configured such that the operator does not instruct the code but automatically determines it. Reference numeral 2 is a first code system external character storage unit for storing an external character storage file in which a font of an external character corresponding to the external character code string of the first code system is registered.

Reference numeral 3 is a code input section for inputting a document file containing a character string of a character of the first code system and a character code of a character which is not a character. Reference numeral 4 denotes a first code system document storage unit for storing a document file containing a character string of a non-gaiji character and an external character code string of the first code system. Reference numeral 5 is a second storage for a document file containing an external character code of a conventional code system (hereinafter referred to as a second code system) that assigns an external character to an undefined area of an existing character code and a character code of a character that is not an external character. Is a code system document storage unit.

Reference numeral 6 denotes a document file including the external character code string of the first code system by reading the document data in advance and detecting the external character identification code before processing the document data by the document data processing unit 15 described later. It is a document file determination unit that determines whether the document file includes the external character code of the second code system. Reference numeral 7 indicates an external character storage file stored in the first code system external character storage unit 2 corresponding to the external character group code in the document file stored in the first code system document storage unit 4 and loaded in advance into a memory (not shown). This is the external character storage file loading unit. Since the external character storage files are divided into groups, even if the total number of registered external characters is large, it is not necessary to load all external characters, so the memory capacity can be small.

Reference numeral 8 denotes a first code system external character determining unit for inputting a code from the document file stored in the first code system document storage unit 4 and determining whether the input code is an external character by the external character identification code. .. Reference numeral 9 is a first code system external character font extracting unit for extracting the external character font loaded in the memory by the external character storage file loading unit 7 according to the code input from the document file and outputting it to the document data processing unit 15. Since the external character file has been loaded into the memory by the external character storage file loading unit 7, the external character font can be taken out at high speed.

Reference numeral 10 is a font file 1 according to a code input from a document file for a font of a non-gaiji character.
1 is a font extracting unit that outputs the document data to the document data processing unit 15. Reference numeral 11 is a font file in which fonts of characters that are not external characters are registered in association with character codes.

Reference numeral 12 is a second code system external character storage unit that stores an external character storage file that stores a font of an external character corresponding to an external character code of the second code system. Reference numeral 13 denotes a second code system external character determination unit, which performs the same processing as the first code system external character determination unit 8 on external characters of the second code system. Reference numeral 14 denotes a second code system external character font extraction unit for extracting an external character font from the external character storage file stored in the second code system external character storage unit 12 according to the external character code input from the document file and outputting it to the document data processing unit 15. ..

Reference numeral 15 is a document data processing unit for displaying and printing. For the sake of simplicity of explanation, an example in which those having the same function are individually provided is shown, but those having the same function may be common. The operation of the external character processing device configured as described above will be described below. First, when registering an external character, the external character registration unit 1 assigns an external character font to a certain code string, and the correspondence between the code and the external character font is registered in the external character storage file. For example, when allocating the external character font “Marutsuki Stock” to the hexadecimal code “75214142790B” and registering it in the external character storage file,
The font generation unit 1a generates an external character font "Marutsuki Stock" according to the operator's operation, the operator instructs the external character code string "75214142790B" corresponding to this external character font, and the instructed external character code string is undetermined. If so, the file generation unit 1c causes the font "Marutsuki Stock" and the external character code string "752141427.
90B "is associated with the group to generate a file. The external character identification code “7521” may be set in advance.

Next, for example, when inputting an external character registered in a document file, when the operator inputs an external character code string corresponding to a desired external character from the code input unit 3, the input external character code string is input. Is recorded in the document file. For example, when inputting the external character “Marutsuki Stock” registered as above, the external character code string “752
When "14142790B" is input, the input code is recorded in the document file.

When a document file including the above-mentioned external character code string of the first code system or a document file including the external character code of the second code system is output, it is output as follows. .. Document file determination unit 6
Pre-reads the document file, recognizes the identifier in the document file, and depending on the presence or absence of the external character identification code, the pre-read document file is either the document file containing the external character code string of the first code system or the second code system. It is determined whether the document file contains the external character code. In the past, the operator selected the device by the document file, but in this way,
Since the document file determination section 6 determines which document file, the operator can output the document file without being aware of which document file. The external character identification code is given to the document file determination unit 6 in advance by a parameter, for example, by an operator.

As a result of the determination, if the document file includes the external character code string of the first code system, the external character storage file loading unit 7 corresponds to the group code of the external character code string of the first code system in the document file. Load the contents of the required external character storage file into memory. For example, if the external character code string "75214142270B" is in the document file, the group code "414" in the external character code string is
The font registered in the external character file corresponding to "2" is loaded from the external character storage unit 2 of the first code system.

Next, the first character system external character determination unit 8 reads the stored code from the document file and determines whether the read code is an external character identification code. If it is an external character identification code, the first character system external character font extraction unit 9 extracts the corresponding external character font from the memory according to the group code following the external character identification code and the external character identification code, and outputs it to the document data processing unit 15. For example, "75" of the external character code string "75214142790B" of the document file
21 "is read, the first character system external character determination unit 8 determines that the external character identification code, and the first character system external character font extraction unit 9 follows the external character identification code" 7521 "and the external character identification code" 4142790
The external character font corresponding to "B" (stock with circle) is taken out from the memory, and the external character code string "75214142790B"
The external character font corresponding to is output to the document data processing unit 15. The document data processing unit 15 displays or prints the output external character.

When the read code is not the external character identification code, that is, the character code which is not the external character,
A font file 11 in which the font extracting unit 10 registers a font of characters that are not external characters in association with a character code.
The corresponding font is extracted from the document data processing unit 1
Output to 5. On the other hand, when the document file input by the document file determination unit 6 is a document file including the external character code of the second code system, the second code system external character storage unit 12 or the font file 11 according to the code input from the document file. The external character font or the normal character font is taken out from and output to the document data processing unit 15.

In the embodiment, the code shown in FIG. 1 is 6 bytes, but the fixed 2 bytes which means the first external character may be omitted and the code may be expressed by 4 bytes, or the identifier may be long. The code may be expressed by several bytes.

[0029]

As described above, according to the present invention, an external character font pattern is converted into an external character identification code, a group code,
The external character identification code that has the same data length as the existing character code but has a different code by the external character storage means that stores it in the file corresponding to the group code by associating it with the external character code string consisting of the external character identification code An external character can be represented by an external character code string consisting of a group code indicating the group to which it belongs and an external character specific code that uniquely corresponds to the font pattern of the external character within the group. By providing the external character code extracting means and the font pattern reading means, it is possible to output the external character code string created.

In addition to this, the control means for selectively activating the first document data processing means and the second document processing means in accordance with the detection result of the presence or absence of the external character identification code in the document data, and the document data. When there is an external character identification code in it, a font pattern loading means for loading into the memory all the font patterns of the external characters stored in the storage means as a file corresponding to the group code of the external character code string including the external character identification code. The effect of being able to use it efficiently is provided by providing such as.
