Abstract

PURPOSE:To attain light weight, small size and thin profile of the titled equipment main body by providing a means converting a specific combination code into a corresponding character code when a conversion key input exists in succession to a substitution key input forming a specific combination code. CONSTITUTION:When a conversion key input exists in succession to a substitution key input with a specific combination code from a keyboard KB having the conversion key and plural substitution keys to form a specific combination code, the specific combination code is converted into a corresponding character code by a code converter CNV. When a numeric key inputs '0', '0', for example, from the keyboard KB, the code corresponds to a character 'A' and is displayed on a display device DSP as 'A'. In applying input as numerals '8', '0', it corresponds to a character 'RA', which is displayed on the display device similarly.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a document creation device such as a Japanese word processor, and in particular to a document processing device that handles Japanese syllabary, etc., in which it is possible to input hiragana etc. using limited keys. This document relates to a document creation device that can be used.

[Prior Art] For example, when trying to input Japanese syllabary in conventional Japanese word processors of this kind, the syllabary layout, JI
A large number of keys, such as the S key layout, must be arranged on the keyboard.

[Problems to be Solved by the Invention] Therefore, due to physical constraints, it has been difficult to make the main body of the device light, thin, short, and small (light and thin, short, and small).

In addition, the large number of types of keys has the disadvantage that it is difficult for the user to handle them.

[Means for Solving the Problems] The present invention aims to eliminate the above-mentioned drawbacks of the conventional document creation device, and for this purpose, a conversion key and a plurality of substitutes for forming a specific combination code are provided. and a means for converting a specific combination code into a corresponding character code when there is a conversion key input following a substitute key input that results in a specific combination code. do.

[Example] The present invention will be described in detail below with reference to the drawings.

FIG. 1 is an external view of one embodiment of the present invention. Here, A is the main body of the document creation machine, with B on the keyboard and the display DSP.
and. The keyboard KB has numeric keys, a "hiragana" key indicating input for hiragana conversion, etc., as will be described later.

FIG. 2 is a block diagram of one embodiment of the present invention.

Here, B is a keyboard, MPU is a microcomputer with a read-only memory (ROM) and registers storing procedures as shown in FIG. 4, and RAM is a random access memory.

The microcomputer MPU takes in a code input from, for example, a keyboard KB through a signal line I1.1, and reads it into a random access memory R through a data bus DB.
Store the code in AM. The code stored in the random access memory RAM is sent to the code converter CNV via the data bus DB as necessary, and is converted into a character code having a correspondence relationship as shown in FIG. to the character generator C6 input.

In response to this, the character generator CG generates a character pattern to the signal line 13, and the display controller C
The data is transferred to the NT, thereby displaying characters on the display port SP.

FIG. 3 is a correspondence table between the 50 syllables (hiragana) and two-digit numerical keys (input values).

For example, press the numeric key from above B on the keyboard to select “°0°.”

When "0" is input, the code corresponds to the character "a", and "a" is displayed on the display device DSP.

Furthermore, if you enter the numerical value ゛8°° 0°°, the character "ra"
Correspondingly, "ra" is also displayed on the display.

FIG. 4 is a flow chart showing the operation of the present invention. First, in step S1, a code is entered into the MPU by key input from the keyboard, and in step S2,
Determine whether it is a 2-digit numeric key input. If it is not a 2-digit numerical key input, the process ends, and if it is a 2-digit numerical key input, the process proceeds to step S3.

In step S3, it is then determined whether there is a "hiragana" key input from the keyboard.

“If the hiragana °° key is not input, the process ends; if the hiragana °° key is input, in step S4, the input numerical code is stored in the random access memory RAM,
In step S5, the above-mentioned hiragana processing is performed by the code converter CNV and character generator CG, and in step S6, the character corresponding to the character code obtained in step S5 is displayed on the display device DSP, and the process ends. .

[Effect of the invention] As explained above, according to the present invention, as in the conventional case,
The number of keys can be significantly reduced by inputting codes such as hiragana using a limited number of keys (for example, numeric keypad, etc.) without configuring a system by arranging the same types of keys on the keyboard. This allows the main body of the device to be made lighter, thinner, and smaller.

Furthermore, according to the present invention, it is easy to generate a wide variety of complex kanji by dividing one kanji into several parts, coding each of the divided parts, and combining the codes by inputting the codes using numerical keys, for example. .
