Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a Japanese input device having a reduced character display function, in particular, a Japanese input device having a function of displaying reduced characters, in particular, image data of standard characters having a standard size such as ordinary Kanji characters, and two characters such as alphanumeric characters. It is configured to prepare image data for reduced characters that can be treated as one standard character by arranging the minutes, and then prepare image data for each reduced character individually, so that multiple image data are prepared when reading. This invention relates to a Japanese language input device that can be used in combination with data.

In a Japanese input device, a word input in kana characters is converted into kanji by operating a conversion key, and a sentence containing kanji is input. In this case, the character code is processed within the device, but if it is to be displayed on a display or printed out on a printer, a character generator is required to generate image data from the character code. . On the other hand, when outputting alphanumeric characters on a display as described above, it is preferable in terms of character arrangement to display, for example, two alphanumeric characters within the size of one kanji character.

Although such alphanumeric characters are referred to as reduced characters in this specification, two characters are treated as one standard character as described above.
The following problem arises when attempting to prepare image data within the generator. That is, for example, English
If you try to prepare image data using two characters of 36 numerical characters as one standard character, for example, aa, ab, ac..., a0...a9, ba, bb...99
As a result, a maximum of 36×36 character types are required, which undesirably increases the capacity of the character generator.

The present invention aims to solve this problem, and the Japanese input device of the present invention having a reduced character display function includes a keyboard and a cursor whose position is controlled by key operations on the keyboard. A control unit, a conversion processing unit that converts input kana characters, a display, a display control unit that controls display on the display, and code information corresponding to the display on the display screen of the display is stored. Equipped with screen code and buffer,
In the Japanese input device that inputs Japanese sentences while converting kana character strings input by key operations on the keyboard into kanji characters, on the character generator that converts character codes into image data, A standard character area and a reduced character area are prepared independently for each character, and one word with a predetermined format corresponds to one character of the character code converted by the conversion processing section in the standard character specification mode. multiple characters of reduced characters are stored in the above screen code buffer as minutes, and in the character code converted by the conversion processing unit in the reduced character specification mode, multiple characters of reduced characters are combined into one word in a predetermined format. and stores it on the screen code buffer, and when reading from the screen code buffer, decodes the character code read from the screen code buffer and converts it to the character code corresponding to the standard character. The above character generator is accessed once to supply it to the printer or the above display, and the above character generator is accessed multiple times in correspondence with the character code corresponding to the reduced character to supply multiple image data of the reduced character. It is characterized in that the characters are combined and supplied to the printer or the above-mentioned display as one standard character. This will be explained below with reference to the drawings.

The figure shows an embodiment of the invention, shown in relation to display on a display. Of course, it can be considered that similar processing is performed when outputting to a printer.

In the figure, 1 is the display, 2 is the keyboard,
3 is a keyboard control unit; 4 is a conversion processing unit that converts input kana character strings into kanji;
5 is an input character buffer; 6 is a dictionary memory; 7 is a flip-flop for indicating reduced character mode; 8 is an encoder for encoding character codes corresponding to standard characters and reduced characters; 9 is a cursor control unit; 10 is a screen code buffer in which, for example, character codes are stored in a form corresponding to the display screen of display 1; 11 is a display control unit that periodically accesses the screen code buffer to display the display 1; 12 is a character code reception register, 1
3 is a decoder that determines whether the character code corresponds to a standard character or a reduced character; 14 is a character generator;
15 represents a row image buffer.

As an embodiment of the present invention, the character code has, for example, #0 bit to #15 bit from the left end in the figure.
Consisting of 16 bits, the character code corresponding to the standard character is as shown in the illustrated screen code buffer 10, with the #2 bit set to logic "1", and the #7 bit and #9 bit to #14 bit set to a logic "1". The standard character is specified using 7 bits of
Also, the character code corresponding to the reduced character is as shown in the screen code buffer 10, with #0 bit set to logic "1" and #1 bit to #7 bit set to logic "1".
Two reduced characters are specified by using bits up to the first reduced character and #9 to #15 bits for the second reduced character.

The character generator 14 has image data for standard characters for each character, and image data for reduced characters for each character. When outputting two reduced characters for display, etc., the image data of each reduced character is read out individually, and then the image data of the size corresponding to one standard character, which is the combination of both characters, is output. They are made to create data. For this reason, even when combining two alphanumeric characters, for example, it is sufficient to have reduced character image data for 36 characters.

In the figure, the cursor is moved by operating keys on the keyboard, and the cursor is placed at a desired coordinate position. In this state, when the user inputs, for example, "Totsukiyo" using the character keys and then presses the conversion key, the dictionary memory 6 is indexed based on the contents of the input character buffer 5. That is, the kanji ``patent'' that matches ``totsukiyo'' in the ``yomibu'' is extracted. This "patent" is of course a character code, and the character code is written via the encoder 8 to the address on the screen code buffer 10 corresponding to the position of the cursor. Note that the role of the encoder 8 will be described later.

The contents of the screen code buffer 10 are periodically read out by the display control section 11 and displayed on the display 1. That is, character codes sequentially read out from the screen code buffer 10 are converted into image data of the characters through the character generator 14. The image data is set in the row image buffer 15 and supplied to the display 1.

To display in standard font size,
The illustrated flip-flop 7 is in a reset state, and the encoder 8 converts the illustrated code S into the character code read out from the dictionary memory 6, for example, the character code corresponding to ``toku'' and the character code corresponding to ``gaku''. The bits are organized as shown below and stored in the screen code buffer 10.

On the other hand, when displaying the reduced character size, the illustrated flip-flop 7 is placed in the set state. When two character codes corresponding to, for example, the character ab are supplied from the dictionary memory 6 or directly from the input character buffer 5, the encoder 8 organizes the bits as shown in the code T and inputs them into the screen code buffer 10. Store.

The display control unit 11 has a screen code buffer 10.
When read out periodically, the code read into the register 12 is decoded by the decoder 13 to determine whether it is a standard character or a reduced character. If the character is a standard character, the gate G1 is turned on and the character generator 14 is accessed. Also, if it is a reduced character, first gate G
2 to access the character generator 14, and then turn on gate G3 to access the character generator 14. In the case of reduced characters, two image data (related to a and b) are accessed twice.
are combined on the line image buffer 15 as if they were one standard character image data. The contents of row image buffer 15 are then provided to display 1.

As explained above, according to the present invention, it is necessary for the character generator 14 to have image data for a maximum of 36 x 36 characters in the form of, for example, two reduced characters combined into one standard character size. Therefore, the storage capacity of the character generator 14 can be saved.

Although the above description has been made using a display as an example, it goes without saying that the present invention can be similarly applied to printer output.
