Abstract

PURPOSE:To perform character conversion at each field, by referring a category table for an arbitrary input code through designation, in a data processor. CONSTITUTION:A character type designation control byte A is provided for each field and classified into a category designation 1(B) and a cataegory designation 2(C). The type of input characters is designated at the cataegory designation 1(B), and special conversion designation is made at the cataegory designation 2(C) and the output code conversion is made with an output table corresponded through the reference of a category table. (D). Thus, the field of document is read with a data processor and the conversion is easily done at the output point of time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a data sensitive device in which when converting an arbitrary input code into an arbitrary output code, the user specifies parameters for table creation in advance without creating a processing program. Concerning a code conversion method that is only possible with

Currently, as a data processing device, for example, an optical character reader (such as an optical character reader) that recognizes and inputs characters written on a form.
There is an OCR device). The OCR device can detect kana characters, numbers,
Nine forms containing complex characters such as alphabetical characters are read. In the reading, for example, if a certain input character code is 74? In Rudo, this is the t＼
Although you want to output a specific value, you may want to convert the code and output it in another field. Specifically, in the form shown in No. 11i1, the fields are defined as ■ and ■, and ■ is a numeric item field, and the input code is output as is as the *U power X operator O symbol, but ■ is a kana item field], and * is a case where the data is converted to arank and output.O If these processes were performed on the same device, conventionally a character conversion program 2 was installed separately. The commonly used character codes for ta0 and ζro are approximately 13
0 class s+), it is a complicated problem to create a conversion program individually to correspond to it, and 90 times g4ov
When defining fields in form processing, a special conversion table corresponding to a designated code is provided to provide a code conversion method that enables character conversion for each field.

A feature of the present invention is that an output code table to be converted is selected based on a conversion specification in a field to be processed and a conversion specification of a category table of an arbitrary input code included in the field, and the conversion is performed into an arbitrary output code. The above purpose has been achieved by the stone.

Hereinafter, a method for realizing the present invention will be specifically explained.

In the form shown in Figure 1, the fields are defined as ■ and ■, and as mentioned above, ■ is a numeric item field, and * is a multiplication operator symbol that indicates the input code and its output code. Sui, ■ is a kana item field, * is a dummy character to match the number of digits, and * is a kana item field.
A method for converting 0 to blank and outputting it will be explained.0 As shown in FIG. 2, a character type designation control byte is provided for each field, and it is divided into category designation 1 and category designation 20. Category specification 1 @ specifies the input character type, and corresponds to input character code 11★
Byte x's of the category table shown in No. 411
Category designation 1 of c' (can be input if the AND with B1 is O).

On the other hand, the category specification 20 controls the conversion of the output code, and if the category specification 2 (C') of the category table 0 shown in No. 311 and the category specification 2 (C') of category table 0 are satisfied, the category specification is The output code table (g) corresponding to code 20 shown in FIG.

For example, when reading field ■02*2-4 in a form as shown in FIG. 1, numbers and symbols are read.

Since there is a multiplication operator, the reading and p character type specification code are 0.
00 00110 When I read 0 books on the OCR machine, I realized that the * in the category table in Figure 3 is 4) x'
sc'0 code is 00000010, the category table is the+, soat\output 0mata, and when reading Honhon Tashizan of field is 00110
010, and when * is read by the OCR device, the code Fio0110010 of byte X '5 C' in the category table aO* in Fig.
C') If the K% special conversion specification is valid, the output code table (3) in FIG. 4 is selected, and the output code blank X'40' of the * byte X'50' is processed.

As mentioned above, a character type specification control byte is provided for each field, and it is divided into category specification 1@, category specification 2 (OK), category specification 1■ specifies the input character type, and category specification 24QK special conversion specification. By referring to the category table 0 and converting the output code according to the corresponding output table 9, the field of the form can be read by the data processing device and converted to the product at the time of output. In the invention, the category specification 20 is 3 bits, so if you correspond with bits, you can specify 3 types of special conversions, and if you use codes, you can specify 7 types of special conversions.
(Not -〇- 0 For example, if it is set to 8 bits, 256 kinds of special conversion specifications are possible. 0 Therefore, if the above I output code table is created by specifying parameters as in the present invention before starting processing, For example, in the above explanation, it is possible to convert all input codes for one conversion specification, but as shown in Figure 5, one conversion specification It is also possible to perform conversion by associating one conversion code with the above.

The present invention has been described above with reference to examples. According to the present invention, in a method for converting an arbitrary input code into an arbitrary output code, an arbitrary input code can be specified by referring to a category table. Then, the corresponding output code table can be used to convert arbitrary output to - code without creating a character conversion program, which has a great effect.4

Figure 2 shows the character type designation control byte, Figure 3 shows the category table, and Figures 4 and 5 show the output code table.
