Description

[Detailed Description of the Invention] (i) Technical Field of the Invention The present invention relates to a code conversion device for a computer system, and particularly to a code conversion device for converting a code specifying a general currency symbol into a code corresponding to a local currency symbol. It is related to the device.

(ii) Technical background In an electronic computer system, consider the case where data is processed through the CPU and outputted to a printer, for example, the result of a monetary calculation. Even though the calculation of numbers in money is common in each country, when we look at the currency symbols that accompany them, there are differences, such as the currency symbol in Japan being "¥" and the currency symbol in America being "$".

(iii) Prior Art and Problems As mentioned above, in order to output currency symbols such as "¥" and "$", the program uses dedicated codes corresponding to each symbol.

Considering the output in countries with different currencies, the program had to be created for each country.

Another solution is to install different print heads for the same code in each country in the printer device.

Therefore, when changing the handling of currency symbols, it is troublesome to change the software for each change, and changing the printer requires labor such as replacing the printer head.

(iv) Purpose of the present invention The present invention aims to eliminate the above-mentioned drawbacks and to make it possible to meet the demand for providing different devices for each country (by currency) without changing the code conversion device by a simple modification. The purpose is

(v) Configuration of the present invention A replaced code setting means for setting a code to be replaced, a replacement code setting means for setting a replacement code, a code sending signal from the code sending section and a replaced code setting means. A comparator that compares the signals with the signals of This is achieved by providing a selector for supplying the code signal from the setting means to the code receiving section.

(vi) Examples of the present invention Embodiments of the present invention will be described in detail below with reference to the drawings.

The figure shows an embodiment of the present invention. In the figure, 1 is a code sending unit, 2 is a code conversion device that converts the code from the sending unit 1 into another code, 3 is a code receiving unit that receives the code from the code conversion device 2, and 4
5 is a replacement code setting means for setting a code to be converted; 5 is a replacement code setting means for replacing a replacement code; 6 is a code sending signal from the code sending section 1 and a code sending signal from the replacement code setting means 4; A comparator 7 compares the signals and outputs a comparison signal, and 7 is a selector that supplies the replaced code to the code receiving section 3 if the comparison signal from the comparator 6 indicates a mismatch, and a replacement code if they match. The replaced code setting means 4, replacement code setting means 5, comparator 6, and selector 7 are provided in the code conversion device 2. Now, we will explain how to convert the currency symbol as a generic term into "$". First, a code (here, "0001") corresponding to a currency symbol as a generic name for all existing currencies is set in the replacement code setting means 4.

A code corresponding to an existing currency symbol (in this case, the code "0100" for the currency symbol "$") is set in the replacement code setting means 5.

Next, the operation will be explained. From the code sending unit 1,
In addition to the generic currency symbol, codes containing various data are also sent. Now, suppose that the currency symbol "0001", which is a general term for all currencies, is sent as a code sending signal. The comparator 6 compares the code sending signal with a preset signal "0001" from the replaced code setting means 4. At this time, since both signals are the same, the comparator 6 outputs a comparison result signal indicating a match to the selector 7. By indicating a match, the selector 7 sends the code "0100" set in the replacement code setting means 4 to the code receiving section 3.

Note that the code receiving section 3 is connected to a printer and outputs the currency symbol "$" corresponding to the code "0100". Next, assume that the code sending signal output from the code sending unit 1 indicates a code other than "0001", for example, "1111".

The comparator 6 compares the code sending signal with the signal from the replaced code setting means 4, and sends a comparison result signal indicating a mismatch to the selector 7. Since the selector 7 receives a signal that the code from the code sending section 1 does not match the code from the replaced setting means 4, it sends the code from the code sending section 1, that is, "1111" as it is to the code receiving section 3. do.

Therefore, when a code other than the code set in the replaced code setting means 4 is sent from the code sending section, it will be sent as is to the code receiving section 3.

(vii) Effects of the Invention As explained above in detail, by using the code conversion device of the present invention, it is no longer necessary to change the program that handles currency codes every time the code changes.

In other words, from the programmer's point of view, it is sufficient to simply create a program for the generic currency code without being aware of each country, which simplifies program creation since there is no need to program each country individually. still,
Although the present invention uses a generic code covering all currency symbols, there is no harm in using a code for a currency symbol, such as "\", instead of a special generic code. Further, according to the present invention, it is possible to easily convert a program for domestic use (a program that handles the currency symbol "¥") into a device for use in other countries.
