Abstract

PURPOSE:To facilitate rule mark input work by providing a display switching means which reads out grid information from a storage means and arranges a grid in an input area. CONSTITUTION:When a switching instruction is issued from an input means 3 in a state where a text on which a control code is set is displayed on an input screen, the display switching means 4 selects and erases the control code displayed on a display means 1, and reads out the grid information from the storage means 2 instead, and arranges the grid in the input area. Therefore, when data requiring the check of position relation with a character is inputted as in the input of a rule mark, only character information can be left on a screen by erasing the control codes of tab and indent, etc., from the screen, and the grid by which the input position of the rule mark can be easily decided can be displayed on the same screen instead. Thereby, it is possible to perform the input and editing work of the rule mark easily and at high speed.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to a character processing device that displays character information as well as control codes related to character input and editing.

(B) Conventional technology Conventionally, in this type of character processing device, when control codes such as tabs, indents, equal allocation, enlarged characters, etc. are set for input character strings, those control codes are The symbol is displayed in front of the symbol.

(c) Problems to be solved by the invention However, although such a control code is convenient for checking the editing status of the input character string, the control code is attached while the control code remains. When trying to input a ruled line near characters, it is difficult to understand the positional relationship between the characters and the ruled line, and the control code becomes an obstacle to the ruled line input operation. Furthermore, when a large number of control codes are set, the screen becomes cluttered, and there is a problem in that it is difficult to find the necessary information on the screen.

This invention has been made in consideration of the above circumstances, so if necessary, control codes such as T on the screen can be selected and erased, and instead a grid can be displayed on the screen that makes it easy to input ruled lines. Provide processing equipment.

(d) Means for Solving the Problems FIG. 1 is a block diagram showing the basic configuration of the present invention. In the figure, the present invention includes a display means 1 for displaying control codes related to character input and editing together with character information, a storage means 2 for storing grid information for arranging a grid within the input area of the display means 1, An input means 3 for inputting a switching instruction for erasing the control code displayed on the display means 1; and an input means 3 for inputting a switching instruction for erasing the control code displayed on the display means 1; display switching means 4 for erasing the grid information and for reading grid information from the storage means 2 and arranging the grid in the input area;
A character processing device comprising:

Control codes in this invention include tabs, indents,
It also includes a control code for equal layout, editing of enlarged characters, etc., and a nostem code for f indicating an uninput area.

In this invention, the term "grid" refers to an index that indicates the position of character placement on the screen, and the grid is composed of a large number of dots arranged in a matrix, and each dot is located at the upper center of one full-width character input frame. It is preferable to configure it so that. However, the grid is not limited to dots, but can also be composed of mesh-like lines.

(E) Effect According to the present invention, when a switching instruction is input from the input means while a text with a control code set is displayed on the input screen, the display switching means changes the display to the display means. The control code is selected and erased, grid information is read from the storage means in its place, and a grid that facilitates the input of ruled lines is placed within the input area.

(F) EXAMPLES The present invention will be described in detail below based on examples shown in the figures. Note that this invention is not limited by this.

FIG. 2 is a block diagram showing the configuration of a Japanese word processor as an embodiment of the present invention.

In the same figure, 10 is a keyboard, which is used to input character input keys for inputting character information, 1 ruled line input key for inputting ruled lines, and control codes related to editing such as tabs, indents, equal allocation, enlarged characters, etc. It is equipped with an editing key for editing, a switching key for switching screens (described later), etc., and allows text information, ruled line information, and various instructions to be transferred to the CPU II (
(described later).

A display device 110 is connected to the CPU II and is composed of a dot matrix type display device such as a CRT or an LCD. This display value 71110 displays characters, ruled lines, control codes, etc. input from the keyboard 10.

12 is a ROM as a storage means connected to the CPU II
The stored contents include a control program for controlling the CPU 1, a kanji conversion dictionary that is input from the keyboard 10 and is referred to when converting character information, and a grid arranged in the input area of the display device 110. grid information for inputting information, a nostem code that indicates an uninput area in the input area of the display device 110 with a symbol "...", and the like.

As shown in Figure 3, the grid is an index G to indicate the arrangement position of the full-width characters A on the screen, and the input frame F (
One dot is given for each virtual boundary representing the space occupied by one full-width character, and a large number of these dots are arranged in a matrix within the input area on the screen. Also,
Each dot is visually displayed so as to be located at the upper center of the input frame F. Note that the grid may be configured so that one dot is given to a virtual boundary representing the space occupied by one half-width character.

13 is RAM, and a mode flag (described later) 13
1. It consists of a work area 132 for temporarily storing intermediate results during program execution, and a document buffer 133 for storing edited documents.

In the conventional kana-kanji conversion process, the CPU II inputs character information from the keyboard 10 and stores it in the ROM 12.
Convert to the corresponding kana or kanji by referring to the kana-kanji conversion dictionary inside. Furthermore, in the screen switching process that is a feature of this embodiment, the following process is performed. That is, if a switching instruction is input from the keyboard 10 while a text with a control code set is displayed on the input screen and a system code is displayed in the non-input area,
The display switching means selects and erases the control code and system code displayed on the display device +10, reads grid information from the ROM 12 instead, and arranges a grid in the input area to facilitate input of ruled lines.

Details of the screen switching process will be explained below according to the flowchart shown in FIG. Note that it is assumed that a text with a control code and a system code are displayed on the screen.

First, when you press the switch key on the keyboard 10, RAM1
Step 2O-21) determines whether the flag is set in the mode flag 131 of No. 3. If the flag is not set, sets the mode flag (Step 22). The control code and system code are stored in the RAM 13.
The grid is removed from the screen by saving it to the work area 132, and the grid read from the ROMI 2 is displayed on the screen instead (step 23). When the mode switching key is pressed again, it is determined that the mode flag has already been set in step 21, and the mode flag is reset (step 24), and the grid displayed on the screen is erased and evacuated. The control code and system code that were found are called out from the work area 132 and displayed respectively (step 25). Note that if a key other than mode switching is pressed in step 20, key-specific processing corresponding to those keys is performed (step 26), and a determination is made as to whether an instruction to redisplay the input screen has been given or not.Step 27 ), if YES, then it is determined whether the mode flag is set (step 28); if YES, the process moves to step 23;
If so, the process moves to step 251.

The display contents of the screen to be changed by the above process are shown in the fifth section.
The figures are shown in (a) and (b), respectively. Figure 5(a)
indicates that the control code, system code, and character information corresponding to step 25 are displayed;
Figure (b) shows a state corresponding to step 23 in which a grid and character information are displayed, and ruled lines are input using the grid as a mark.

(g) Effects of the Invention According to this invention, when inputting data that requires checking the positional relationship with characters, such as inputting ruled lines,
Control codes such as tabs and indents can be deleted from the screen, leaving only text information on the screen, and instead a grid can be displayed on the same screen that allows you to easily determine the input position of ruled lines, so you can easily You can easily and quickly input and edit ruled lines, etc. whose positional relationship is important.
