Abstract

PURPOSE:To attain the efficient use of a storage means and to improve the operation convenience of the storage means with omission of undesired jobs by deleting automatically the space codes existing between a line feed code and another code except the space codes. CONSTITUTION:A deleting means 5 is provided to delete the space codes existing between a retrieved line feed code and an identified code as long as the code identified by a code identifying means 4 is identical with another code except the space codes. Then a retrieving means 3 retrieves a line feed code out of those codes inputted from an input means 1 and stored in a storage means 2. The means 4 identifies the type of the code that is stored in the means 2 earlier than the line feed code. If the identified type of code is identical with a code except the space codes, the means 5 deletes the space codes existing between the retrieved line feed code and a code except the identified space codes.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] This invention relates to a document processing device.
More specifically, the present invention relates to a document processing apparatus having a function of automatically deleting a space when a space exists between an input character string and a line feed code.

0002

2. Description of the Related Art Conventionally, a document processing device is programmed with a document editing function so that document information input from a keyboard is stored in a RAM, which is a storage device, and simultaneously displayed on a display device such as a CRT. It is constructed using a microcomputer.

[0003] Among the document editing functions, there is a function for deleting character strings. Normally, the function for deleting strings is to delete each character.
Alternatively, it is configured so that multiple characters can be deleted at once by specifying a range. Deleting a character string increases the free space in the storage area on the storage device.

0004

[Problem to be Solved by the Invention] When inputting document information, a certain sentence is input and a line break is performed. In this case, the line feed code is stored in the RAM along with the input text. A space code indicating a space may be stored just before the line feed code. These space codes are often unnecessary and therefore waste RAM storage space. By deleting such space codes, the storage area can be used effectively.

[0005] However, when deleting these unnecessary space codes, it is necessary to delete them one by one or after specifying a range, which is very time-consuming.

The present invention has been made in consideration of the above circumstances, and aims to provide a document processing device with a space deletion function that can automatically delete unnecessary space codes that exist before line feed codes. It is something.

[0007]

[Means for Solving the Problems] Figure 1 is a block diagram clearly showing the configuration of the present invention. As shown in the figure, the present invention has character codes, space codes, and line feed codes corresponding to various characters. an input means 1 for inputting at least
A storage means 2 that stores each code input from the input means 1 in the order in which it was input; a search means 3 that searches for line feed codes stored in the storage means 2; and a line feed code searched by the search means 3. A code identification means 4 that sequentially identifies the type of previously stored code, and a code identified as a line feed code retrieved when the code identified by the code identification means 4 is a code other than a space code. This is a document processing device with a space deletion function, which includes a deletion means 5 for deleting the space code between the two spaces.

[0008]

[Operation] The search means searches for a line feed code from among the codes inputted by the input means and stored in the storage means. When a line feed code is searched, the code identification means identifies the type of code stored in the storage means before the line feed code, and if the type of code is a code other than a space code, the deletion means is searched. The space code between the new line code and the code other than the identified space code is deleted.

[0009] As a result, the area of the storage means in which unnecessary space codes were stored can be freed and used, and the storage means can be used efficiently.

EXAMPLES Examples of the present invention will be described in detail below with reference to the drawings, but the present invention is not limited to the following examples. FIG. 2 is a block diagram showing the configuration of an embodiment of the invention. This embodiment assumes a Japanese word processor.

In FIG. 2, 11 is a keyboard, 12
is a CRT (cathode ray tube) that displays input document information. The keyboard 11 and CRT 12 are the central processing unit 1
It is electrically connected to 3. The keyboard 11 functions as an input means in combination with the central processing unit 13.

The central processing unit 13 includes, for example, a 16-bit microcomputer, a code generation circuit that converts signals from the keyboard 11 into character codes, space codes, line feed codes, etc., a character generator, a CRT controller, a video RAM, and the like. , operated by a document editing program stored in the program memory 14.

A document memory 15 stores character codes, space codes, line feed codes, etc. input from the keyboard 11 and output from the central processing unit 13 at addresses specified by the microcomputer in the order in which they were input.

Next, the operation of deleting a space code between a line feed code and a code such as a character code in this embodiment will be explained with reference to the flowchart shown in FIG. Note that the operation related to inputting a Japanese document is the same as that conventionally known, so a description thereof will be omitted.

First, the central processing unit 13 stores the text memory 15.
A line feed code is searched from among the various codes stored in (step 100). Next, it is determined whether a line feed code is found (step 101), and if it is not found, the operation of deleting the space code is terminated. Step 1
If it is determined that a line feed code has been found in step 101, the type of code immediately preceding the line feed code is identified (step 102). That is, this identification operation is to check the type of code stored before the line feed code is stored. Here, the code stored first refers to the code stored in descending addresses from the address where the line feed code is stored, if the input codes are stored in ascending order of addresses. .

Determine whether the code identified in step 102 is a space code (step 103
). If it is not a space code, step 100 is executed again, and if it is a space code, the type of code immediately before the space code is further identified (step 104). It is determined whether the identification result is a space code (step 105). If it is a space code, step 104 is executed again.

If a plurality of space codes are stored for each address younger than the address where the line feed code is stored, steps 104 and 105 are repeatedly executed. If it is determined in step 105 that it is not a space code, a line feed code and step 10
All space codes existing between the space code identified in step 4, such as the character code, are deleted from the document memory 15 (step 106).

This space code deletion operation may be accomplished by executing the process shown in the flowchart shown in FIG. 3 every time a line feed code is input when document data is input. Furthermore, when the operator inputs an instruction to "delete spaces" from the keyboard, for example, the deletion operation may be performed on the document called up for editing according to the flowchart shown in FIG. .

[0019]

[Effects of the Invention] According to the present invention, space codes that exist between line feed codes and codes other than space codes are automatically deleted, so that storage means can be used efficiently and such space codes can be deleted. The work required to delete the information is no longer necessary, improving usability.
