Abstract

PURPOSE:To perform the numeral processing without providing a new operation key by deciding the just preceding shift key. CONSTITUTION:When a key is inputted on a keyboard 12 and the key code is detected by a CPU 11, it is decided whether a clause/next candidate key is operated or not. If it is discriminated that it is not operated, it is decided whether the operated key is an alphanumeric shift key, HIRAGANA (cursive form of Japanese syllabary) shift key, another shift key, a HIRAGANA key, or a numeric key. That is, it is decided whether the inputted character is alphanumeric or not before input of HIRAGANA; and if it is not alphanumeric, it is decided whether an input buffer 15 is empty or not, and contents of the input buffer 15 are written in a document area if it is not empty.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a document creation device having a number word processing function.

(Prior Art) Document creation devices (Japanese word processors) that create documents by inputting kana characters and converting them into kanji characters have become very popular. When creating a document using such a document creation device, for example, the numerical word "first" (first
), and if you want to input the number ``1'' after ``dai'', you can only do so after operating the alphanumeric shift key. However, when alphanumeric shift is used, input cannot be confirmed without conversion, so a separate non-conversion key is provided, or alphanumeric shift is used to confirm non-conversion, and numbers are input using the numeric keypad.

(Problems to be Solved by the Invention) As described above, when performing number word processing, it must be performed using non-conversion keys or numeric keys, which has the drawback of increasing the number of operation keys.

The present invention has been made in view of the above points, and its object is to provide a document creation device having a number word processing function that can perform number word processing without providing a new key.

C Invention configuration (means and action for solving the problem) Input buffer?
A key discriminating means for discriminating the operated key in the document production device stored in the text-area after kana/kanji conversion is performed when the conversion key is operated. When the determination means detects an operation of an alphanumeric shift key, a hiragana shift key, or another shift key, the current shift state stored in the current shift state storage means is stored in the old shift state storage means, and the current shift state storage means a shift state storage means for storing an alphanumeric shift, a hiragana shift, and other shifts; and when an operation of a hiragana shift key is detected by the key discrimination means, the old shift state stored in the old shift state storage means is stored. is not an alphanumeric shift and there is data in the input buffer, writes the data in the input buffer to the document area, and if the old shift state is an alphanumeric shift, waits for the next key input, and uses the above key discrimination means to input alphanumeric characters. A means for detecting that a key other than a numeric shift key, a hiragana shift key, or another shift key has been operated and inputting data corresponding to the key into an input buffer when the key is a hiragana or numeric key; When the operation of an alphanumeric shift key is detected by the determination means, if the old shift state stored in the old shift state storage means is not Hiragana shift and there is data in the input buffer, the data in the input buffer is converted into a document. area, and if the previous shift state is Hiragana shift, waits for the next key input, and the above key discrimination means detects that a key other than the alphanumeric shift key, Hiragana shift key, or other shift key has been operated, and the key If the key is hiragana or a number, the document creation device is provided with means for writing data corresponding to the key into an input buffer.

(Embodiment) A document creation device having a number processing function according to an embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 11 is a CPU (CPU) that performs various controls in document creation.
central processing unit). Key operation signals are input to this CP tJ 11 from a keyboard 12 on which keys necessary for document creation are arranged.

For example, this keyboard 12 has an alphanumeric shift key that is operated when inputting alphanumeric characters, a hiragana shift key that is operated when inputting hiragana, a katakana shift key that is operated when inputting katakana, and a katakana shift key that is operated when inputting alphanumeric characters. In addition to the alphabetic symbol shift key, there are provided a kana/kanji conversion key that is operated when converting kana characters input into the input buffer 15 into kanji. Also, 1
3 is a ROM (read-only memory) in which programs necessary for document creation (including a kana/kanji conversion means for converting hiragana stored in the input buffer 15 into kanji), dictionaries, etc.; 14 is a RAM (Random access
memory). As shown in Figure 2, this RAM 14 has a text area where created sentences are stored, a current shift flag C8F that stores the currently selected shift key (current shift key), and a current shift flag C8F that stores the currently selected shift key (current shift key). An old shift flag ○SF for storing a selected shift key (old shift key) and an input buffer 15 for storing kana characters to be converted into kana/kanji input from the keyboard 12 are provided.

Next, the operation of an embodiment of the present invention configured as described above will be explained. The flowchart shown in FIG. 3 shows the operation of the number word processing function according to the present invention. First, when a key input is made from the keyboard 12, the CPU
11, the key code is detected and step S
1). Thereafter, it is determined what the key code is.

First, it is determined whether the clause/next candidate key has been operated (step S2). If rYEsJ is determined, the kana characters stored in the input buffer 15 are converted into kanji by the kana/kanji conversion means and stored in the document area in the RAM 14 (step S3.84).

If rNOJ is determined in step S2, whether or not the operated key is an alphanumeric shift key (step S5);
It is determined whether it is a hiragana shift key (step S7), whether it is another shift key (step 312), and whether it is a hiragana or number (step 514).

Here, if the alphanumeric shift key is operated, the contents of the current shift flag C8F will change to the old shift flag O8.
The alphanumeric shift flag is stored in the current shift flag C8F (step 86).

Also, when the hiragana shift key is operated, the contents of the current shift flag C8F change to the old shift flag O.
3F, and the hiragana shift flag is stored in the current shift flag C8F (step 38). Then, it is determined whether the old shift flag O8F is an alphanumeric shift flag (step S9). That is, before inputting hiragana, it is determined whether the input characters are alphanumeric characters or not.

Here, if it is determined that it is not an alphanumeric character, it is determined whether the input buffer 15 is empty (step $10). If the input buffer 15 is not empty, the contents of the input buffer 15 are written to the document area (step 511).

For example, there is a case where hiragana etc. are directly layered into the text area. By the way, the above step S9 or 3
If rYEsJ is determined in step 10, step S
Processing No. 11 is skipped.

By the way, if it is determined in step S7 that the result is rNor, the process advances to step S12. When another shift key such as a katakana shift key is operated, the contents of the current shift flag C8F are stored in the old shift flag O3F, and the other shift flags are changed to the current shift flag C3F.
(step 513). In this way, when the shift key is operated, the previous shift key state is memorized.

If there is no other shift key, it is determined whether the input key is a hiragana number or not (step 514).

If it is a hiragana number, the hiragana or number is input into the input buffer 15 (step 515).

If the word is neither hiragana nor numbers, the word is written in the document area.

For example, if you operate ``daiJ (alphanumeric shift r'+J (hiragana shift) ``kai''), input buffer 1
5 can input "Daichi kai" (step 515). Thereafter, when the "sentence jlD/next candidate" key is operated, "daiichikai" stored in the input buffer 15 is converted into "first time" by the kana/kanji conversion means and written into the document area.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a document creation device capable of processing number words.
