Abstract

PURPOSE:To process the character data including the character codes of a fixed order within a character data processor despite an optional input order by rearranging the input character codes in the order of level values. CONSTITUTION:A keyboard 1 serves as an input means that can perform the input of the character data especially the tie character data that is expressed in plural character codes. An input interface 2 produces the level values, e.g., 'normal=1', 'high or low=2' and 'superhigh=3' in response to the input character codes. These level values are stored in a memory 4 together with their corresponding character codes. Then a CPU 3 rearranges the order of character codes supplied in the order of said level values. Thus the same characters or the same data can be normalized regardless of the input order of the character codes showing a single character. Then the operation efficiency and the operability are improved and the correct analysis of characters is ensured with a character data processor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is utilized for processing character data of a character series, in particular Thai character data, in which each character is represented by one or more character codes. In particular, it relates to the input of such character data. The invention is particularly applicable to telegraph exchange equipment.

〔overview〕

The present invention provides a character data processing device capable of inputting character data represented by a plurality of character codes, which generates a level value corresponding to the input character code and rearranges the character codes in the order of the level value. This allows correct character data to be obtained without depending on the input order of character codes.

[Conventional technology]

In Thai characters, each character is represented by 1 to 3 (till) parts. Therefore, in character data processing equipment that allows such characters, especially telegram exchange equipment, a different character code is assigned to each part and the Character data is represented by a combination.

[Problem that the invention seeks to solve]

However, in conventional Thai character data processing devices, depending on the input order of character codes, even the same character (or word) may be recognized as data of different characters (staves). For example, three parts: normal, high and super high.
h, 5upper high), or normal, low and super high (normal, low).

In the case of Thai characters composed of There are two ways, 2 → 1 → d,
There are two types: high, normal, low and super high-1. If these characters are input in a different order, they will be recognized as different characters even though they are the same character.

For this reason, the operator must strictly adhere to a certain input order, making input work cumbersome and causing input errors.
It had the disadvantage of poor operational efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a character data processing device that recognizes character data without depending on the input order of character codes.

[Means for solving problems]

The character data processing device of the present invention is characterized by comprising means for generating a level value corresponding to an input character code, and means for rearranging the input character codes in the order of the level value. do.

[For production]

The character data processing device of the present invention rearranges character codes input in an arbitrary order in the order of level values.
Even if the input order is arbitrary, the device can process character data whose character codes are in a fixed order.

〔Example〕

FIG. 1 is a block diagram of a character data processing apparatus according to an embodiment of the present invention. In this embodiment, the present invention is implemented in a telegram station terminal in a telegram exchange apparatus.

This device handles character data represented by multiple character codes,
In particular, a keyboard 1 is provided as an input means capable of inputting Thai character data, and an input interface 2 is provided as a means for generating level values corresponding to input character codes. A central processing unit 3 and a memory 4 are provided as means for rearranging the order. Furthermore, this device has an output interface 5 for sending the rearranged character codes to the telegraph exchange network.
Equipped with. The keyboard l is connected to the input interface 2, and includes an input ink face 2, a central processing unit 3, and a memory 4.
and output interface 5 are connected to each other by a bus.

FIG. 2 shows the control flow of the embodiment device.

When the operator inputs Thai characters from the keyboard 1, a character code in 1-byte units is output to the input ink face 2. In Thai characters, one character is represented by a character code of 1 to 3 bytes.

The input interface 2 generates level values, for example, "normal=1", "high or low=2J, r super high=3" in response to the input character code. This level value is stored in the memory 4 along with its character code. This data is hereinafter referred to as "initial input data."

The central processing unit 3 sorts the initial input data according to level values. The data obtained by this will be referred to as "normalized input data" hereinafter. This normalized input data is used as forwarding address and other data in the telegram exchange device.

FIG. 3 shows the relationship between initial input data and normalized input data. (a) shows five Thai characters, (b) and (
C) shows initial input data and normalized input data corresponding to that character, respectively.

FIG. 4 shows the flow of rearrangement control by the central processing unit 3. Here, the input character code is m bytes in total, and the level value for the nth byte character code is f (
n).

The central processing unit 3 sequentially compares the initial input data with adjacent data starting from the first byte. If the level value of the nth byte of data is greater than or equal to 1, and the level value of the n-1st byte of data is greater than the level of the nth byte of data, then n
- Replace the 1st byte with the nth byte data. This process is repeated until the end of the data.

Through the above processing, the initial input data is replaced with the normalized input data. In this way, if three characters are input to make up one character, even if the input order of high or low and super high is reversed, normal will be followed by high, or low will be followed by high. Normalized input data is obtained, and the same character data is not recognized as different data.

〔Effect of the invention〕

As explained above, the character data processing device of the present invention has the following features:
Character data of a character series in which each character is represented by one or more character codes can be normalized as the same character or data without being affected by the input order of character codes representing one character. Therefore, operational efficiency and operability are improved, and character analysis can be performed correctly.

INDUSTRIAL APPLICABILITY The present invention can be applied to a device for Thai characters, particularly a telegram exchange device that accepts Thai characters, to great effect.
