Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a character processing device, and particularly to improvements in inputting a blank code F into a created document in operations such as document creation and editing using key input. It is related to.

[Prior Art] In a conventional character processing device such as a word processor, when a document is first created, a blank code whose digits have no meaning as characters is stored in a document buffer. A blank code looks the same as a blank, but a blank has a positive meaning that a blank character is stored in that digit. On the other hand, a blank code has no such meaning and simply indicates that no characters are stored in that digit.

For example, in the editing process such as right alignment and centering,
Spaces between characters are preserved, but blank codes are ignored and compressed. In addition, in equal allocation, the blank code provides information on the spacing of blank characters that are evenly allocated between valid characters.

On the other hand, all characters and symbols such as kana keys are treated as information valid for variable creation and editing.

For this reason, in order to change characters and symbols that have been entered into blank codes when creating or editing a document, conventionally it was necessary to delete the characters one by one or insert a new blank code itself through complicated steps. However, the operation is troublesome.

In addition, these insertion, deletion, and other processes cause disadvantages such as changing the arrangement of characters in the document, which hinders effective document creation.

[The problem that the invention attempts to solve]

SUMMARY OF THE INVENTION An object of the present invention is to provide a key input device with a key for inputting a blank code, and to enable the blank code to be input into the document buffer using the blank code key, thereby solving the above problems. An object of the present invention is to provide a character processing device that can dramatically improve the speed of document creation and editing.

C1 (Second means for solving problem 1) In order to achieve this purpose, the present invention provides an input means for inputting a blank code that has no meaning as a document or a character, and a method for storing the input document. A storage means for determining a blank code from input from the input means, and a means for writing the determined blank code into a document stored in the storage means.

(Function) According to the present invention, a blank code can be input into a document being created by a simple key operation similar to inputting ordinary characters.

(Examples) Hereinafter, the present invention will be described in detail with reference to drawings showing examples.

FIG. 1 shows an example of the configuration of the present invention.

Here, 101 is an input means such as a keyboard for inputting documents and blank codes that have no meaning as characters. The input document is stored in the storage means 102.

The input from the input means 101 is also supplied to the discriminating means 103, which discriminates the blank code from among the inputs. The determined blank code is written by the writing means 104 to a desired location in the document already stored in the storage means 102.

FIG. 2 shows a more specific embodiment of the present invention, in which 1 is a keyboard having a Japanese key KK, a control key CK, and a blank key BK as input means.

In this example, the blank code is input by pressing the blank key BK while pressing the control key CK. However, the blank code input means is not limited to this example, and may therefore be one dedicated key.

2 is a central processing unit (c
pu) and does not indicate the address of the document buffer BB in the random access memory (RAM) 3 in the random access memory (RAM) 3 that stores information input from the keyboard 1, and the cursor register CR
is built-in, and according to predetermined procedures,
Controls each component described below.

3 is readable/writable random access memory (RAM)
), and is used to store the document buffer BB for storing input characters and symbols, or for storing intermediate data necessary for the CPU 2 (7) control operation.

Reference numeral 4 denotes a read-only memory (ROM) in which control procedures for the CPU 2 and blank code display patterns, which will be described later in FIG. 2, are stored.

5 is a display device including a CRT or the like. When data is written into the document buffer BB via the pass line 7 under the control of the CPU 2, characters or the like are displayed on the CRT or the like by corresponding dots.

Reference numeral 6 denotes a printer that prints out the contents of the document buffer BB in the RAM 3. A pass line 7 supplies control signals from the CPU 2 to each of the 114 devices making up the system, and also transmits and receives data.

FIG. 2 is a flowchart showing an example of the control procedure of this embodiment.

The operation of this embodiment will be described below with reference to FIGS. 1 and 2.

First, in steps S1 and S2, it is determined whether or not a key is input from the keyboard 1. If there is a key input, the process proceeds to step S3, where the CPU 2 determines whether or not the input key input is a blank code. judge. Here, if the input key input is not a blank code, the corresponding code is processed.

On the other hand, if the entered key input is a blank code, that is, if the blank key BK is pressed while pressing the control key CK, eight cursor registers CR built in the CPU 2 are entered in step S4. A blank code is stored in the corresponding location of the document buffer BB pointed to by .

Next, in step S5, a blank code pattern is displayed at the cursor position on the screen of the display device 5,
In the next step S6, the contents of the cursor register CR are updated and the cursor is advanced by one digit.

By repeating the above operations, the work of inputting blank codes into the created document is continued one after another.

[Effects of the Invention] As explained above, according to the present invention, it is possible to input a blank code into a document being created by a simple key operation similar to inputting ordinary characters, and therefore it is possible to input a blank code into a document being created. It won't mess up the layout.

As a result, not only the number of key inputs for document creation and editing is reduced, but also erroneous operations can be prevented. In this way, according to the present invention, effective document creation can be realized.
