Abstract

PURPOSE:To realize an input of a Japanese sentence including Chinese characters just by writing the phonetic symbols such as HIRAGANA (Japanese syllabary) letters, etc., by writing the phonetic symbol trains to a coordinate region and the characters excluding Chinese characters to the other coordinate region. CONSTITUTION:The position coordinate signals of a coordinate input device 1 are supplied to a region discriminator 2 and a character recognizer 3, and the position coordinate signal and the holograph due to a time change of the coordinate signals are analyzed. The characters on the device 1 are recognized, and the cooresponding character signals are generated and transmitted to a switch means 4. Then the discriminator 2 discriminates a coordinate region (1-A) or (1-B) of the device 1 that contains the position coordinate signals and then supplies the region discriminating signals to the means 4. In this case, the means 4 transmits the character signals to a character output terminal 7 in case the region discriminating signal indicates the region (1-A) and then to a character converter 5 in case the region (1-B) is indicated respectively. The converter 5 converts the character signals into different ones and then supplies them to the terminal 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character input device used in a device for creating a document composed of a plurality of character groups having different properties, such as a Japanese document.

Conventionally, the method of inputting Japanese text is to input kana characters using a key switch and convert some of them into kanji. Characters are written directly onto a so-called kana-kanji conversion device or a coordinate input device, and the characters are recognized. There were so-called online character recognition devices. The former method converts the text into kanji by inputting the reading using keys and pressing a switch that instructs the conversion, but it is generally difficult to operate 60 types of keys, and the switch that instructs the conversion is difficult. There were disadvantages such as the need to operate the

The latter allows characters to be entered by simply writing the characters directly, but on the other hand, it is not so easy to write kanji correctly, and the disadvantage is that ordinary users tend to misrecognize them. .

The present invention eliminates the above-mentioned drawbacks of conventional character input devices, and allows you to input sentences containing kanji by simply writing phonograms such as hiragana, katakana, katakana, or romaji, which correspond to the pronunciation of the sentence you want to input. This allows input. The present invention will be explained in detail below.

The drawing is a main part block diagram showing an embodiment of the present invention.

In the figure, a coordinate input device 1 detects the position of two-dimensional coordinates specified by a coordinate designator 6 and outputs a coordinate position signal related to the coordinate position, which is a well-known data tablet. .

In addition to a digitizer, a device that indicates the position using a light pen on a CRT may also be used.

The coordinate plane of this coordinate input device 1 is divided into at least a first coordinate area (1-A) and a second coordinate area (1-B). Here, the first coordinate area (1-A) is an area used when characters written on it are output as is without conversion, and the second coordinate area (1-B) is This is an area used when the characters written on it are output after being converted.

Although the coordinate input device 1 is divided into two parts in the illustrated embodiment, it may be configured to have more divided areas. A position coordinate signal output from the coordinate input device 1 is supplied to an area discrimination device 2 and a character recognition device 3. The character recognition device 3 analyzes the supplied position coordinate signal and the handwriting, which is a temporal change in the position coordinate signal, and recognizes the character written on the coordinate input device 1, and recognizes the recognized character. A character signal corresponding to the character signal is output and transmitted to the switch means 4. The area determination device 2 determines that the supplied position coordinate signal is a first coordinate area (1-, A) on the coordinate plane of the coordinate input device 1.
) or the second coordinate area (1-B), outputs an area discrimination signal, and switches the switch means 4 to
supply to.

The switch means 4 controls the transmission destination of the character signal supplied from the character recognition device 3 in response to the area discrimination signal. In other words, the area discrimination signal indicates the first coordinate area (1-
A), the character signal is transmitted to the character output terminal 7, and when the second coordinate area (1-B) is designated, the character signal is transmitted to the character conversion device 5. to be transmitted. The character conversion device 5 converts the supplied character signal into a different character signal, and then supplies the converted character signal to the output terminal 7. For example, a signal string indicating hiragana is converted into a signal string indicating kanji.The above hiragana may be katakana or romaji.

According to the configuration of the above embodiment, for example, when inputting a Japanese sentence, when inputting a phrase including kanji, the phonetic character string such as hiragana characters or katakana characters corresponding to the reading is input as the second character string. It is only necessary to write characters other than kanji in the first coordinate area, and there is no need to operate a key switch at all.

As is clear from the explanation in section 2 below, the present invention does not require the user to operate any key switches at all, and it is possible to input Japanese sentences including kanji simply by writing long letters such as hirakana. It provides a character input device, and its effectiveness is quite impressive.
