Abstract

PURPOSE:To improve the operability for input of half size characters by converting the characters inputted from a key input means into half size characters only when a half size shift key is pushed. CONSTITUTION:A full size input mode is saved into an input mode memory 24 with push of a half size shift key 20a, and a half size input mode is set. When characters are inputted with the key 20a kept pushed, these characters are converted into half size characters. The half size characters whose conversion are fixed are stored in a sentence memory 22. When the key 20a is released, the full size input mode is called out of the memory 24. Thus the full size input mode is reset and it is judged whether the conversion process is through or not. Then the input characters are converted into full size characters as long as the key 20a is not pushed. Thus it is not required to switch the input mode for each input of a half size character when the half size characters are inputted in a full size input mode. Then the sentence production efficiency is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to character processing devices such as Japanese word processors and office computers, and more particularly to a character processing device capable of inputting half-width characters.

(b) Prior Art Conventionally, the two major character modes in Japanese word processors are full-width input and half-width input.

When entering full-width or half-width characters, the operator selects the input mode by switching the full-width/half-width input camo-1 switch key each time, and then inputs the full-width or half-width characters. was going on.

(c) Problems to be Solved by the Invention However, in such conventional Japanese word processors, when half-width characters are partially input when creating sentences using the full-width input mode, the following operations are required. That is, press the manual mode switching key to switch the current full-width input mode to half-width input mode, then input characters,
Furthermore, after inputting characters, it was necessary to press the switch key again to return the half-width input mode to the full-width input mode.

Such operations have the problem of reducing the efficiency of text creation because character input is interrupted.

The present invention has been made in consideration of the above circumstances, and provides a character processing device that improves the operability of inputting half-width characters.

(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 key manual means 1 having a half-width knot key, a dictionary means 2 storing a large number of full-width characters as well as half-width characters, and a dictionary that stores only half-width characters when the half-width shift key is pressed. This is a character processing device including a half-width character reading means 3 for reading out the half-width characters from the means 2, and a display means 4 for displaying the read half-width characters.

In this invention, full-width characters refer to normal-sized characters such as hiragana and kanji (the vertical and horizontal sizes of the characters are almost the same), and half-width characters refer to characters whose width is half that of full-width characters. show.

Although it is preferable to use a keyboard as the key manual means 1 of the present invention, a pointing device such as a tablet input device or a mouse may also be used. Dictionary means 2
is composed of a ROM, and specific examples of this ROM include a hard disk built into the word processor itself and an external storage device such as a floppy disk. The half-width character reading means 3 is included in the CPU, and has an 8-bit configuration, for example.
A CPU with a 16-bit configuration or a 32-bit configuration can be used. The display means 4 can be comprised of a dot matrix type display device such as a CRT display or an EL display.

(E) Function According to the present invention, only when the half-width knot key is pressed, the character manually input from the key manual means is converted into a half-width character.

(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 to this.

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

In the figure, 20 is a keyboard, which has a character entry key for inputting characters, a conversion key for performing kana-kanji conversion, and a half-width shift key 20a for selecting a half-width input mode.

2I is a conversion dictionary serving as a dictionary means, and stores a large number of full-width characters and half-width characters.

Reference numeral 22 denotes a text memory, which stores full-width characters or half-width characters read from the conversion dictionary 21 and confirmed to be input.

23 is a CRT, which includes full-width characters and half-width characters read from the conversion dictionary 21 and displays various information.

Reference numeral 24 denotes an input mode memory for storing input modes set from the keyboard 20, and is composed of a stack.

25 is a CPU, which performs processing to be described later in accordance with a control program written in a program memory 26. In other words, in conventional kana-kanji conversion, the keyboard 20
A word corresponding to the kana character string inputted from the conversion dictionary 21 is read out from the conversion dictionary 21 and output to the CRT 23. Furthermore, in the half-width conversion process that is a feature of this embodiment, only half-width characters are read from the conversion dictionary 2I and output to the CRT 23 when the half-width shift key 20a of the keyboard 20 is pressed.

The half-width conversion process will be explained in detail below according to the flowchart shown in FIG. Note that it is assumed that the full-width input mode is initially set.

First, press the half-width shift key 202L (step 30
), the full-width input mode is saved in the input mode memory 24 (step 31), and the half-width input mode is set (step 32). Next, when characters are input while holding down the half-width shift key 20a (step 33), the input characters are converted to half-width characters (step 34), and the converted half-width characters are stored in the text memory 22 (step 35). . Next, it is determined whether the half-width shift key 20a, '+' has been released or not (step 36). In other words, when the half-width shift key 20a is released, the input mode memory 2
The full-width input mode is restored by calling the full-width input mode from 4 (step 37), and then it is determined whether the conversion process is completed (step 38). If the conversion is still in progress, the process returns to step 30. Step 30
If the half-width shift key 20a is not pressed in step 39-40, the input characters are converted to full-width characters (steps 39-40).
). Note that if NO in step 36, that is, if the half-width knot key 20a remains pressed, step 33
, and the conversion of half-width characters continues.

(G) Effects of the Invention According to this invention, half-width characters are converted only while the half-width shift key is held down, so when entering half-width characters in full-width input mode, each time a half-width character is input, There is no need to operate mode switching, and therefore the efficiency of writing can be improved.
