Abstract

PURPOSE:To improve the operability by providing a means for deciding a character kind of an input character-string, an attribute imparting means for imparting an attribute to the input character-string by this character kind, and a switching means for instructing whether an effect of both the means exists or not. CONSTITUTION:In the case a character code inputted from a character input circuit 1 is a character code input example 5, a character kind deciding circuit 3 decides a fact that 0x31, 0x32, 0x8252 and 0x8253 are numerals, and 0x82a0 and 0x82a2 are 'KANA' (Japanese syllabary) from the character code. An attribute imparting circuit 4 imparts a half size attribute and a full size attribute to the numeral and the 'KANA', respectively from the character kind decided by the character kind deciding circuit 3. In this state, when the half size attribute is shown by one byte code, and the full size attribute is shown by two bytes, the attribute imparting circuit 4 executes a processing for changing 0x8252 and 0x8253 to 0x33 and 0x34, respectively, and can match the attributes of every character kind. In such a way, with respect to a character-string input in which different character kinds are mixed, the operation for imparting the attribute comes to be scarcely executed, and the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a character processing device that assigns character attributes depending on the character type of a character string in character processing.

BACKGROUND OF THE INVENTION Conventional character processing devices input character strings containing a mixture of alphanumeric characters, kanji, kana, symbols, etc.
If you wanted to change the attributes of each character type, you had to switch the attributes at the beginning of that character type. Moreover, this attribute change is not done for each character type, but when inputting alphanumeric characters and kanji using Romaji-Kana-Kanji conversion in a Japanese processing device,
First, enter alphanumeric mode, and if you want to add half-width attributes to alphanumeric characters, change to half-width mode, enter alphanumeric characters,
If I wanted to enter kanji next, I had to switch back to full-width mode and kana mode, and then manually input kanji.

Problem to be Solved by the Invention 2 Therefore, in conventional character processing devices, although a specific attribute is often assigned to one character type, there is no correspondence between the character type and the attribute, making operation difficult. has become complicated. In particular, considering the balance of characters, numbers in documents are often half-width, and kanji characters are often full-width.With the JIS keyboard of conventional Japanese processing devices, numbers can be input even while inputting Roman characters. Switching between half-width manual mode and full-width input mode occurred frequently, resulting in poor operability.

In addition, in Japanese language processing devices that use the well-known Shift JIS code system, which includes a mixture of 1-byte code and 2-height code, attributes are determined based on the number of bytes in the character code, so for example, the number "1" is 1 byte. So half-width, 2-bye!・
However, there were some inconveniences such as full-width characters.

The present invention takes this into account and aims to provide a character processing device with good operability by automatically assigning attributes in accordance with character types.

Means for Solving the Problems In order to achieve the above object, the character processing device of the present invention includes a character string manual means, and a character type determination for determining the character type of a human character string manually input from the character string input means. means and
The character type determining means includes an attribute assigning means for assigning an attribute to the input character string according to the character type from the character type determining means, and a switching means for instructing whether or not the character type determining means and the attribute assigning means are effective.

Effect: In the character processing device of the present invention configured as described above, when the user uses the switching means to instruct automatic assignment of attributes, the character type of the input character string input manually from the character input means is changed. The character type determination means determines an attribute corresponding to the character type, and the attribute assigning means assigns an attribute to each character of the human-powered character string, thereby assigning a specific attribute to each character type of the human-powered character string, and thus, This eliminates the need to change attributes in response to changes in character types, making it possible to realize a character processing device with good operability. In addition, if the user does not instruct the dynamic addition of attributes using the line switching means, the device functions as a normal character input device.

Embodiment FIG. 1 is a block diagram showing the operation of a character processing device in an embodiment of the present invention, in which l is a character input circuit, 2 is a switching circuit, 3 is a character type determination circuit, and 4 is a character type determination circuit. This is an attribute assignment circuit.

The operation of the character processing device of this embodiment configured as described above will be explained below. FIG. 2 shows an example of a character code input from the character input circuit 1 when automatic attribute assignment is instructed by the switching circuit 2, and the output of characters after attribute assignment in the same embodiment and the conventional example. In the figure, 5 is an example of a character expressed as a character code input from the character input circuit 1, 6 is an example of character output after attribute assignment in the same embodiment, and 7 is an example of a character output in the conventional example. This is an example of character output after attributes are added.

In this embodiment, it is assumed that the user uses the switching circuit 2 to instruct automatic assignment of attributes, and the character code input manually from the character input circuit 1 is character code input example 5. This character code input example 5 is a known shift JIS code.

Character type determination circuit 3 reads 0x31.0x32 from the character code.
．． 0x8252.0y8253 is a number, 0x82
It is determined that aO1Ox82a2 is a pseudonym. The attribute assigning circuit 4 assigns half-width attributes to numbers and assigns full-width attributes to kana based on the character type determined by the character type determining circuit 3. In this embodiment, if a half-width attribute is represented by a 1-byte code and a full-width attribute is represented by 2 bytes, the attribute assignment circuit 4
is 0x8252 to 0x33, 0x8253 to 0x34
It becomes possible to align the attributes for each character type, resulting in a character output example 6 in this embodiment.

In character output example 7 according to the conventional example, the numbers "1" and "2"
is half-width, and the numbers "3" and "4" and the kana characters "a" and "i" are full-width.

Although this example shows only the case where the character types are numbers and kana, the character types may be anything that can be distinguished on the character code, and combinations of types such as kanji and kana, specific kanji and other kanji, etc. It is possible.

In addition, in this embodiment, the operation of the attribute assigning circuit 4 includes half-width,
Although the full-width attribute has been described, it is also possible to add underlining, shading, etc. Further, the user of the present character processing device may instruct that a specific attribute be assigned to a specific character type.

Note that in this embodiment, a case is shown in which the switching circuit 2 instructs automatic attribute assignment, but if the switching circuit 2 does not instruct automatic attribute assignment, the character output for character code input example 5 is The example is the same as character output example 7 in the conventional example.

Further, the character string input means may be a known kana-kanji conversion device or may be a keyboard.

Further, the attribute assigning means may assign fixed attributes to character types, or the user may instruct the correspondence between character types and attributes, and assign attributes specified by the user to the specified character types. You may.

As described in detail, according to the present invention, it is possible to realize a character processing device with good operability by reducing the number of operations for adding attributes to input character strings containing a mixture of different character types.

Furthermore, the components of the present invention do not require large-scale components and can be realized with a small device.

Therefore, a very effective character processing device can be realized, and its practical effects are great.
