Abstract

PURPOSE:To operate a cancel key on the way of input to simplify the cancel operation by cancelling input data if input data exists in an input buffer and output data does not exist in an output buffer when the cancel key is operated. CONSTITUTION:When a key on a keyboard 12 is operated, the key code is read into a CPU 11. If this key is the cancel key, it is decided whether KANA (Japanese syllabary) characters to be subjected to KANA/KANJI (Chinese character) conversion are inputted or not. If data exists in an input buffer 15 and data does not exist in an output buffer 16, it is decided that data is inputted, and the input buffer 15 is cleared, and a document in a document area before input is displayed again on an LCD 17.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a document creation device having a function of permitting cancellation during kana/kanji conversion input.

(Prior Art) Document creation devices (Japanese word processors) that create documents by inputting kana characters and converting them into kanji have become very popular. In such document creation devices, the cancel key cannot be used during kana/kanji conversion input.

(Problem to be solved by the invention) For this reason, if you want to press the function key while inputting data to be converted into kana/kanji, use the "←" key to move past the beginning of the characters that have already been input. You had to go back to 1 or press the hiragana key to confirm, making the key operations cumbersome.

The present invention has been made in view of the above points, and an object thereof is to provide a document creation device having a function of permitting cancellation during kana/kanji conversion input.

[Structure of the Invention] (Means and effects for solving the problem) In a document creation device that converts kana characters stored in an input buffer into kanji, there is provided a key discriminating means for discriminating an operated key; If the key determination means detects that the cancel key has been operated, input data exists in the input buffer, and if output data does not exist in the output buffer, the input data is stored in the manual buffer. This is a document creation device equipped with means for erasing.

(Embodiment) A document creation device according to an embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1↑ is a CPU (central processing unit) that performs various controls on document creation. Key operation signals are input to the CPU 11 from a keyboard 12 on which keys necessary for document creation are arranged. For example, this keyboard 12 has a cancel key, an alphanumeric shift key to be operated when inputting alphanumeric characters, a hiragana shift key to be operated to input hiragana, a katakana shift key to be operated to input katakana, and an alphanumeric shift key to input alphanumeric characters. In addition to the alphabetic symbol shift key, which is operated when the input buffer 15 is pressed, a kana/kanji conversion key is provided, which is operated when converting kana characters input into the input buffer 15, which will be described later, into kanji. Reference numeral 13 denotes a ROM (read/write 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 and outputting the converted characters to the output buffer 16), a dictionary, etc. only memory), 1
4 is RAM (Random Access Memory).

As shown in FIG. 2, this RAM 14 is provided with a document area (not shown) in which created sentences are stored, an input buffer 15, and an output buffer 16.

In this way, the created document is sent to an LCD (liquid crystal display) 11 and displayed.

Next, the operation of an embodiment of the present invention configured as described above will be explained. First, when a key on the keyboard 12 is operated, the key code is read into the CPU 11 (step Sl). If the key is a key other than the cancel key (step S2), processing for that key is performed (step 83).

On the other hand, if the key is a cancel key (step S2), it is determined whether or not a kana to be converted into kana/kanji is being input (step S4).

It is determined that data is being input when there is data in the input buffer 15 and there is no data in the output sofa 16. In other words, if the data is being input, the data is not yet stored in the output buffer 16 because it has not been converted into kana/kanji. Above step S
In the determination of step 4, if it is determined that input is not in progress, processing is performed in another state. For example, processing such as canceling printing is performed.

On the other hand, if it is determined in step S4 that input is in progress, the input buffer 15 in which the kana to be converted is input is cleared, and the document in the document area before the kana to be converted is input is displayed on the LCD 17. It will be displayed again. In this way, it is possible to operate the cancel key to cancel the input while inputting the kana to be converted into kana/kanji.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to operate the cancel key to cancel the input while inputting the kana to be converted into kana/kanji, thereby simplifying the operation to cancel the input. It is possible to provide a document creation device that can be used to create documents.

Claims (1)

[Claims] In a document creation device that converts kana characters stored in an input buffer into kanji characters, there is provided a key discrimination means for discriminating an operated key, and a key discriminating means for discriminating an operated key, and a key discriminating means for detecting that a cancel key has been operated.
