Abstract

PURPOSE:To reduce the trouble in mode switching, errors in operation, etc., by inputting characters and symbols in the 2nd mode without any change in mode when the characters and symbols in the 2nd mode need to be inputted while characters and symbols in the 1st mode are inputted. CONSTITUTION:When an alphanumeric conversion key 1a is pressed while KANA (Japanese syllabary) characters inputted on a keyboard 1 are inputted to an input buffer 2 and also displayed on a display part 3, a KANA- alphanumeric conversion part 7 is actuated. Then, a CPU sends the codes of the stored KANA characters to the KANA-alphanumeric conversion part 7, which refers to a code conversion table 8 to extract corresponding alphanumeric character codes. The converted alphanumeric character codes are written in a document memory 6, the KANA character codes before being converted into the alphanumeric codes are erased from the input buffer 2, and the converted alphanumeric characters are displayed on the display part 3. Thus, when alphanumeric characters need to be inputted in KANA mode, the alphanumeric characters are inputted without any change in mode.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for inputting characters and symbols in Japanese word processors, personal computers, and the like.

. [Prior art and its problems] In conventional Japanese word processors, etc., when inputting from a keyboard etc. in the first character/symbol mode, some characters/symbols in the second character/symbol mode are input. If so, first switch the mode to the second character/symbol mode, then switch back to the first character/symbol mode [If you need to continue inputting and there are fewer characters to input in the second character/symbol mode, If the user inputs data in places without continuous operation, he or she may forget to perform the mode switching operation, or the mode switching process may cause an open chain, such as requiring time and effort to input the data.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to easily input characters/symbols in the second mode when inputting characters/symbols in the first mode.
The purpose of the present invention is to provide a code conversion method that allows input of characters and symbols in this mode.

[Key points of the invention]

In order to achieve such an object, the present invention includes a character/symbol conversion section, a conversion table section, and a character/symbol conversion key on the keyboard.
The second character/symbol can be converted into a second character/symbol that shares a key on the keyboard.

[Embodiments of the invention]

The configuration and operation of an embodiment of the present invention will be described below with reference to FIGS. 1 to 3. First of all, Figure 1 shows a block configuration diagram. 1 is a keyboard, which includes keys for inputting kana, alphanumeric characters, and symbols, and keys for inputting kana and kanji characters that convert input pronunciation character strings into kanji and kana mixed sentences. In addition to keys for requesting conversion, function keys for performing each editing operation, cursor keys, etc., keys for converting kana alphanumeric characters (hereinafter referred to as "alphanumeric conversion") convert kana character strings into corresponding alphanumeric strings. , key) la is provided. 2 is an input buffer, 3 is a display unit, 4 is a display drive unit, 5 is a CPU, 6 is a document memory, 7 is a kana/alphanumeric conversion unit, and 8 is a code conversion table. , 9 is a flowchart of the present embodiment for kana-kanji conversion.Kana characters input from the keyboard l enter the input buffer 2. In step 1, the CPU converts the code of the kana character stored in the input buffer 2 into kana alphanumeric characters. In step 2, the kana/alphanumeric character converter 7 collates the code conversion table 8 and extracts the corresponding alphanumeric character code.In step 3, the converted alphanumeric character code is stored in the document memory 6. , In step 4, erase the kana character code before being converted to the alphanumeric character code in the input buffer 2.In step 5, the converted alphanumeric character code is displayed on the display unit 3.The display during input in this case We will further explain the correspondence between the parts and the operation. Figure 3 is an input example when you want to input "This is CaXX085.-" and the text contains alphanumeric characters. .The shaded part of the display indicates undefined characters.First, in display a, ``This is'' is written in hiragana.

This shows the state in which ``be'' has been input, and in operation a, press the key r on the keyboard 1 and press ``Enter''.You can leave it as is, so press the no conversion key to confirm. In the display and operation, I want to input 'c ax) < o 85J, so I press the hiragana key r, which corresponds to 'caxxo85J,' on the keyboard. When you press the alphanumeric conversion key in operation C, the r letter that you have already input will be displayed as 'ca, xx' in operation C.

85, is converted and finalized as follows. In operation d, ``,'' can be left in hiragana as in display a, so use the no conversion key to confirm at the end.
You can enter x o 85. this.

Thus, in this embodiment, if you want to input alphanumeric characters in kana mode, you can input alphanumeric characters without changing the mode. Furthermore, although this embodiment deals with kana to alphanumeric character conversion, conversion between hiragana and katakana, conversion between hiragana and symbols, etc. can be similarly realized by changing the contents of the conversion table. Furthermore, in this embodiment, the characters in the input buffer are converted, but if characters in a specified section of the document in the document memory are converted, the desired text can be converted even after the text has been finalized. can convert characters.

〔Effect of the invention〕

As explained above, according to the present invention, when inputting characters/symbols in the first mode, if you want to input characters/symbols in the second mode, you can input the characters/symbols in the second mode without switching the mode. Since input is possible, there is no need to switch to the second mode, enter the characters/symbols of the second mode, and then return to the first mode, which has the effect of reducing the hassle of mode switching and operational errors. .

Claims (1)

[Claims] A code conversion table between the first character/symbol and the second character/symbol shown on the key top of the same key, and the first or second character/symbol shown on the key top using this code conversion table. It has a conversion unit that converts a character or symbol into a second or first character/symbol, and a conversion execution instruction means that activates the conversion unit, so that the input character/symbol can be converted into another character/symbol of the same key. A code conversion method characterized by the following.
