Abstract

PURPOSE:To remove a fault of an mismatched external character between character files including external characters. CONSTITUTION:When an instruction for copying a required document file including external characters which is stored in one storage medium to a document file including external characters which is stored in the other storage medium is outputted, a CPU 4 retrieves either one of the copy destination and the storage medium at the copy source detects the existence of external characters in the document file stored in the retrieved storage medium and controls the start of copying of the document file including the external characters based upon the detected result.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device for editing a document by using a registered external character.

[0002]

2. Description of the Related Art Conventionally, in this type of device, an external character different from a character registered in advance, for example, a user's logo, a mark, a character in a user typeface, etc., can be registered so that a unique document can be edited. It is configured.

When storing texts and external characters in a device of this type, for example, a Japanese word processor, the texts and external characters have been considered as independent entities stored in separate memory areas. This makes it easy to use an external character once created in other sentences. Furthermore, since each external character has one memory area, it has the advantage of being easy to manage.

[0004]

However, since the sentence and the external character are completely independent as described above, a plurality of external character-containing sentences are combined into one, for example, one external character-containing sentence is combined with another external character-containing sentence. When copying to a file, etc.
There was a problem that it became the processing of.

External characters cannot be copied.

External characters in the text on the copy side are not copied.

External characters in the copied text are overwritten and erased.

The present invention has been made in order to solve the above-mentioned problems, and when copying another external character-containing document file to an external character-containing document file, the copying process is controlled while collating the external character registration information. Accordingly, it is an object of the present invention to obtain a character processing device capable of removing an external character failure that causes inconsistency between external character containing document files.

[0009]

A character processing device according to the present invention, when a desired external character mixed document file stored in one storage medium is copied to a desired external character mixed document file stored in the other storage medium, Detecting means for detecting the presence or absence of external characters in the document file by searching each storage medium of the copy destination or the copy source, and controlling the start of copying the document file containing the external characters between the storage media based on the detection result of this detecting means. And control means.

[0010]

According to the present invention, when the instruction to copy the desired external character mixed document file stored in one storage medium to the desired external character mixed document file in the other storage medium is made, the detection means causes the copy destination or The storage medium of the copy source is searched to detect the presence / absence of external characters in the document file, and the control means controls the start of copying of the document file in which external characters are mixed between the storage media based on the detection result. It is possible to avoid in advance the influence on the external character information on the document file stored in the.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram for explaining the structure of a character processing apparatus showing an embodiment of the present invention, and the structure and operation will be described below.

A CPU (Central Processing Unit) 4 controls each device connected through a bus line 10 by executing the contents of a program memory contained in the ROM 3. The keyboard 1 is connected to the bus line 10, and the character information input from the keyboard 1 is
It is supplied to and stored in the text memory in a part of the RAM 2 via the bus line 10. The stored character information is displayed as a font in the corresponding CG (character generator) 7 on the CRT 5 via the bus line 10 under the control of the CRT controller 6 according to the instruction of the CPU 4. The character information is also printed by the printer 9 under the control of the printer controller 8. An FDC controller 11 drives and controls a floppy disk drive (FDD) 12 to read and write document information. In addition, the floppy disks FD1 to FD3 serving as a document storage medium are mounted, and each floppy disk
The text files read from the disks FD1 and FD2 are expanded on the RAM2. In addition, it is assumed that a document file containing external characters is already written in each floppy disk FD1, FD2.

In the character processing device thus configured, a desired external character mixed document file stored in one storage medium (floppy disk FD1) and an external character mixed document file stored in the other storage medium (floppy disk FD2). When an instruction to copy is given to the detection means (CPU
4) searches the storage medium of the copy destination or the copy source to detect the presence / absence of external characters in the document file, and based on this detection result, the control means (CPU 4) starts copying the document file containing the external characters between the storage media. It controls and avoids the influence on the external character information on the document files stored in both storage media in advance. In the present embodiment, the control unit and the detection unit are the CPU 4
However, each means may be configured by independent hardware.

The copying process of a document file containing external characters in the character processing apparatus according to the present invention will be described below with reference to the flowchart shown in FIG.

FIG. 2 is a flow chart showing an example of a copy processing procedure of a document file containing external characters in the character processing apparatus according to the present invention. It should be noted that (1) to (5) indicate each step.

Assuming that the contents of each floppy disk FD1 are copied to each floppy disk FD2, each floppy disk FD1 and FD2 is attached to the floppy disk drive 12, and the floppy disk FD2 is read from the keyboard 1 from the keyboard 1. To copy the files of the above to the floppy disk FD1 or the floppy disk FD
When the instruction to copy the disk No. 2 to the floppy disk FD1 is input, the copying process is started (1), it is judged whether the external character already exists on the copying floppy disk (2), and if NO, the copying process is performed. Normally ends (3), and the process ends.

On the other hand, if the result of the determination in step (2) is YES, a message is displayed on the CRT 5 to notify the operator (4), the copying process is forcibly prohibited (5), and the process is executed. To finish.

When a document file containing mixed external characters is copied as described above, the influence on the external characters already stored in the copy destination floppy disk can be removed in advance, and the disappearance and modification of the external characters can be reliably protected.

[0019]

As described above, according to the present invention, a desired external character mixed document file stored in one storage medium
When an instruction is made to copy to the document file with external characters mixed in the other storage medium, the detection means searches the storage medium of the copy destination or the copy source to detect the presence or absence of external characters in the document file, and controls based on this detection result. Since the means is configured to control the start of copying the document file with external characters mixed between the respective storage media, it can be registered in one storage medium which may occur when copying the document file with external characters mixed from one storage medium to the other storage medium. It is possible to avoid the loss and modification of external characters in advance.

Therefore, it is possible to reliably protect the external character of each document file in which the external character code is the same but the external character having a different font form exists from the influence of the document file copying process.
