Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monetary data change processing method, and more particularly to a monetary data change processing method when the value of money data is changed at a certain date or time.

[0002]

2. Description of the Related Art For example, data processed by a deposit slip or a sales slip handled by a department store is usually composed of date data indicating the date of the sales and the like, and amount data indicating the amount of the sales. Such data is input to a data processing device such as a computer and processed by a program called so-called business application software. For example, the total amount of sales for one day, one week, one month, etc. is calculated.

By the way, the amount data may be changed at a certain date or time. For example, when there is a denomination (hereinafter referred to as a denomination), the value of the amount is changed such that 1000 yen is changed to 1 yen at a certain date (the nominal unit of money is changed). .

Further, when a product is sold at a department store or the like for a limited time at a price lower than the list price (hereinafter referred to as a time sale), the value of money for the department store or the like is different at a certain time. . That is, since the same item was sold, the actual amount of sales is aside,
The meaning of the amount data within the time sale time is different from the meaning of the amount data of other time.

[0005]

For example, in the case of the above-mentioned denomination, if 1000 yen is changed to 1 yen, even if the face value of the amount data is the same before and after the date of the denomination, the value is 1000. There is a double difference. For this reason, it is not possible to handle the same amount of data before and after the denomination implementation date, or to compare them as they are. Therefore, it is necessary to handle the monetary amount data before and after the denomination implementation date uniformly (with the same standard) by some means.

On the other hand, when the monetary amount of 1,000 yen of the face value before the denomination implementation date already stored in the storage device is read out after the denomination implementation date and output to the display device or the like, the current amount data is It becomes necessary to display the value, that is, one yen.

It is an object of the present invention to provide a monetary amount data change processing system capable of changing monetary amount data according to a predetermined rule on the basis of a certain date or time according to a predetermined rule.

It is another object of the present invention to provide a monetary amount data change processing system which modifies and stores monetary amount data input at a certain date or time. Another object of the present invention is to provide a monetary amount data change processing method for changing and outputting monetary amount data stored at a certain date or time.

FIG. 1 is a block diagram of the principle of the present invention, showing a data processing apparatus according to the present invention. This data processing device includes a first amount data storage unit 51 for storing first amount data, a second amount data storage unit 52 for storing second amount data, and a time data storage unit for storing time data. Part 2, a time table 6 that stores a reference time that serves as a reference for determining time data, a time comparison processing unit 3 that compares the time data with the reference time, and a rule for changing the first amount data. An operation rule table 7 to be stored, and an operation processing unit 4 for performing operations on the first amount data according to the rules for changing the first amount data.

The time comparison processing unit 3 includes a time data storage unit 2
And the reference time read from the time table 6 is compared. As a result of this comparison, when the time data is within the range specified by the reference time, the arithmetic processing unit 4 stores the first amount data stored in the first amount data storage unit 51 according to the rule read from the arithmetic rule table 7. The calculation for changing the amount data of 1 is performed. Then, the calculation result is written in the second amount data storage unit 52 as the second amount data.

On the other hand, as a result of the comparison, when the time data is out of the range specified by the reference time, the first amount data is left as it is or the second amount is used as it is. Write to the data storage unit 52.

[0012]

For example, when a denomination in which 1000 yen is changed to 1 yen is carried out on a certain date, the denomination execution date is stored in advance in the time table 6 as a reference time.
Further, the calculation rule table 7 stores in advance rules for changing the amount data. This rule is a rule for converting the first amount data according to the same standard and treating them uniformly.

The time comparison processing unit 3 compares the time data with the reference time. As a result of this comparison, when the time data is within the range designated by the reference time, the arithmetic processing unit 4 changes the first amount data according to the rule and then the second amount data storage unit. Write to 52. If it is out of the range, the time comparison processing unit 3
The monetary amount data is written as it is in the second monetary amount data storage unit 52. As a result, the input data can be converted by the same standard and stored in the second amount data storage unit 52, and can be handled in a unified manner.

[0014]

FIG. 2 is a block diagram of an embodiment, showing a data processing device. In this embodiment, the input / output device 1 is the input device 11
And the output device 12, and the arithmetic processing unit 4 includes an arithmetic processing unit 41 and an inverse arithmetic processing unit 42. In addition, since this embodiment is an example of performing processing based on the denomination implementation date when there is a denomination, the time table 6 is composed of the date table 6A, and the time comparison processing unit 3 is composed of the date comparison processing unit 3A.
Consists of.

The processing unit 20 comprises a CPU (central processing unit) and a memory. Each of the processing units 3A, 41 and 42 is realized by a program and a CPU existing on this memory. As the areas 8, 9 and 10, a predetermined area on this memory or a register of the CPU is used. The CPU has a CPU timer 2A. The CPU timer 2A is actually provided in the processing device 20, and is used as the time data storage unit 2 or as a means for forming the time data stored in the time data storage unit 2.

The input device 11 is for inputting predetermined data based on a deposit slip or a sales slip. This data is composed of, for example, at least amount data indicating the amount of sales, and may be provided so as to be accompanied by date data (time data) indicating the date of the sales. This monetary amount data corresponds to the first monetary amount data, and its value is not always unified by the same standard.

The data input from the input device 11 is temporarily stored in the input data receiving area 8 which is its data buffer in the processing device 20. The input data receiving area 8 is used as the first amount data storage unit 51. Thereafter, this data is taken out by the date comparison processing unit 3A, subjected to predetermined processing, and stored in the second amount data storage unit 52.

If the amount data is not accompanied by time data, the CPU timer 2A is used as the time data storage unit 2. That is, the time indicated by the CPU timer 2A is used as time data of the money amount data,
It is compared with the reference time.

When the amount data is accompanied by time data, the time data is compared with the reference time. In this case, the time data storage unit 2 is the first amount data storage unit 5
It can be said that it is attached to 1. In this way, the time data is attached to the amount data when the operator first inputs the time data together with the amount data from the input device 11, and secondly, the processing (input of the attached amount data is performed). ), The time indicated by the CPU timer 2A is taken in as the time data, and the time data storage unit 2
This is the case when writing in.

The output device 12 is composed of a display device or a printing device, and is for outputting (displaying or printing) data input from the input device 11 or data subjected to a predetermined process. This data also comprises at least monetary data. This monetary amount data corresponds to the second monetary amount data, and is data after being unified to the same standard as other data.

The data output from the output device 12 is temporarily stored in the output data set area 9 which is a data buffer by the date comparison processing section 3A or the inverse calculation processing section 42. The output data set area 9 is the second amount data storage unit 5.
Used as 2. This data is then sent to the output device 12 and output.

The storage device 5 comprises an external storage device such as a magnetic disk, and is provided with first and second amount data storage units 51 and 52. The second amount data storage unit 52 is the data input from the input device 11, and is the date comparison processing unit 3
The data that has been subjected to predetermined processing by A and the arithmetic processing unit 41 is stored. This monetary amount data is data after being unified to the same standard as other data.

Here, the first and second monetary amount data storage units 51 and 52 in the storage device 5 are conceptual, and in practice, there is no distinction. That is, when the amount data stored in the storage device 5 is stored, it is written from the input data receiving area 8 (corresponding to the first amount data storage unit 51) through the date comparison processing unit 3A. The storage device 5 is the second amount data storage unit 52, while the amount data is output to the output data set area 9 (corresponding to the second amount data storage unit 52) via the date comparison processing unit 3A. In the case of one, the storage device 5 is the first amount data storage unit 51.

Date table 6A and calculation rule table 7
Is a predetermined area of the memory that constitutes the processing device 20, or
It is provided in a predetermined area of the external storage device. Date table 6
A stores a reference date as a reference time, that is, a denomination implementation date (specific date). The calculation rule table 7 is
Stores rules based on the contents of denominations, that is, the devaluation rate of currency.

In the present embodiment, in the case of denomination execution, regardless of whether the data input from the input device 11 is data before or after denomination execution, the storage device 5
In principle, the value is changed to the value before the denomination is stored, and in the output device 12, the value is changed (in principle) in the value after the denomination is performed and output (displayed). That is, the monetary amount data is handled uniformly within the processing device 20 under the same standard of the value hit before the denomination is carried out, and is dealt with under the same standard of the value hit after the denomination is carried out at the time of outputting. As a result, the human being can know the value hit according to the currency unit actually being executed, while the processing device 20 can eliminate the need to change the amount data before the denomination.

Therefore, in this embodiment, when the post-denomination amount data input from the input device 11 is written to the storage device 5 (for storage or storage processing), the change to the data before the denomination is calculated. It is executed by the processing unit 41.
Also read from storage device 5 (before and after denomination)
The money amount data and the money amount data before denomination input from the input device 11 are output to the output device 12 (for output processing).
In this case, the inverse operation processing unit 42 changes the data according to the standard after denomination.

The date comparison processing unit 3A has a date table 6A.
To read the denomination implementation date. Then, using this denomination implementation date as a reference, a day before this date (a day before the denomination) and a day after this day including the day of the implementation day (a day after the denomination) are distinguished. Further, the date comparison processing unit 3A reads the data by referring to the time data storage unit 2. As the date data, if the time data storage unit 2 is attached to the amount data, the date data is used. If not, the date indicated by the CPU timer 2A is used.

In the case of the above-mentioned storage processing, the date comparison processing unit 3
A compares the date data of the data to be processed with the denomination implementation date to determine whether the data is data before the denomination or after the denomination. For data before the denomination, the date comparison processing unit 3A temporarily stores the data in the storage device delivery area 10. This data is then written to the storage device 5. In the case of data after the denomination, the date comparison processing unit 3A sends the data to the arithmetic processing unit 41.

Therefore, in the case of the saving process, the data before the denomination is outside the range specified by the reference time (date) (non-calculation target), and is saved (stored) as it is.
On the other hand, the data on the day after the denomination is included in the range specified by the reference time (calculation target), and is subjected to the change process.

In the case of the above-mentioned output processing, when the data to be processed is the data input from the input device 11, the date comparison processing section 3A compares the date data of the data to be processed with the denomination execution date, It is determined whether the data is data before the denomination or data after the denomination. For data after the denomination, the date comparison processing unit 3A temporarily stores the data in the output data set area 9. This data is then output to the output device 12. In the case of data before the denomination, the date comparison processing unit 3A sends the data to the inverse calculation processing unit 42.

Therefore, in this case, the data on the day after the denomination is out of the range designated by the reference time (date) (non-calculation target) and is output as it is. on the other hand,
The data before the denomination is included in the range specified by the reference time (calculation target), and is subject to the change process.

When the data to be processed is the data written in the storage device 5 by the above-mentioned storage processing, the date comparison processing section 3A sends the data to the inverse calculation processing section 42. .

That is, in this case, in the storage process, the data after the denomination is also changed by the process in the arithmetic processing unit 41 (described later) so as to be unified with the standard of the value before the denomination is carried out. ing. Therefore, the data before and after the denomination are both within the range specified by the reference time (calculation target) and are subject to change processing.

In the output processing, if the data to be processed is the data written in the storage device 5 without undergoing the above-mentioned storage processing, the data before and after the denomination are both unchanged. It is written without being processed by the arithmetic processing unit 41.

Therefore, in this case, the date comparison processing unit 3A
Compares the date data of the data to be processed with the denomination implementation date, and determines whether the data is data before the denomination or after the denomination. For data after the denomination, the date comparison processing unit 3A temporarily stores the data in the output data set area 9. This data is then output to the output device 12. In the case of data before the denomination, the date comparison processing unit 3A sends the data to the inverse calculation processing unit 42.

Therefore, in this case, the data on the day after the denomination is out of the range specified by the reference time (non-calculation target) and is output as it is, while the data on the day before the denomination is output on the reference time. Is within the range specified by (operation target), and is subject to change processing.

The calculation processing section 41 uses the calculation rule table 7
To read the rule used by itself. The rule (first rule) used by the arithmetic processing unit 41 is a rule for uniformly handling all data within the processing device 2 according to the same standard. In the present embodiment, all data is processed before denomination execution. It is a rule for performing change processing so as to follow the same standard of being worth. The first rule is stored in the calculation rule table 7 in advance.

When the arithmetic processing unit 41 receives the data from the date comparison processing unit 3A, the arithmetic processing unit 41 applies the first rule to the first amount data and changes it. Then, the first data is made data including date data and the changed second amount data, and then the storage device delivery area 10
Store once to. This data is then written to the storage device 5. Therefore, the second monetary data follows the value set before the denomination.

In the arithmetic processing unit 41, it is desirable to add a flag or pseudo date data to the date data of the data. If the denomination is carried out on April 1st, for example, this pseudo-date data will be displayed on March 32nd, 4th.
As on the 0th day of the month, the date is before the day of the denomination and is not possible in reality. As a result, the date comparison processing unit 3A
Can know that the data read from the storage device 5 is the data on the day after the denomination and the data processed by the arithmetic processing unit 41. That is, it can be known that even the data on the day after the denomination should be the target of the arithmetic processing in the inverse arithmetic processing unit 42.

The inverse operation processing unit 42 refers to the operation rule table 7 and reads out the rule used by itself. The rule (second rule) used by the inverse calculation processing unit 42 is a rule for uniformly handling all data by the same standard when outputting all data to the output device 12. In the present embodiment, all data is processed. This is a rule for performing a change process so as to follow the same standard as a value after a denomination is performed. The second rule is stored in advance in the calculation rule table 7.

The inverse calculation processing section 42 is a date comparison processing section 3A.
When receiving the data from, the second rule is applied to the amount data of the first data to change it. Then, the first data is made into data consisting of the date data and the changed second amount data, and then temporarily stored in the output data set area 9. This data is then output to the output device 12. Therefore, the second monetary data follows the price after the denomination.

Next, for example, when a denomination is implemented in which 1,000 yen is changed to 1 yen on April 1,
This will be specifically described. In the case of the saving process, when the sales “10 yen” of “March 25” is input from the input device 11, the date comparison processing unit 3A does not perform the calculation, and the data is written in the storage device 5 as it is. On the other hand, the sales of “April 5th” is “10
When "Yen" is input, the date comparison processing unit 3A sets it as a calculation target, and the calculation processing unit 41 calculates the amount data "10".
Yen is changed.

Since the denomination rate is such that 1000 yen is 1 yen, "10 yen" is changed to "10000 yen". That is, the amount data is multiplied by 1000. Therefore, the first rule in the calculation rule table 7 is “10
It is instructed to multiply the amount data by “00” (× 1000).

Here, the calculation of 10 × 1000 is equivalent to moving the decimal point position of the amount data rightward by three digits. Therefore, in the present embodiment, the first rule is to instruct to move the position of the decimal point of the amount data to the right by three digits.

The calculation processing section 41 uses the calculation rule table 7
Read this first rule from "10 yen"
Change to "0 yen". As described above, the sales “10 yen” on “March 25” and the sales “10000 yen” on “April 5” are written in the storage device 5.

In the case of the output process, when the sales “10 yen” of “April 5” is newly input from the input device 11, the date comparison processing unit 3A does not perform the calculation and outputs it to the output device 12 as it is. To be done. On the other hand, sales of "March 25th""1
When "0 yen" is input, the date comparison processing unit 3A sets it as a calculation target, and the inverse calculation processing unit 42 changes the amount data "10 yen" to "0.01 yen".

That is, the amount data is multiplied by 1/1000. Therefore, the second rule in the calculation rule table 7 multiplies the amount data by “1/1000” (× 1/1).
000). Actually, in the present embodiment, the second rule instructs to move the position of the decimal point of the amount data to the left by three digits.

As a result of the above, sales of "March 25""0.0"
“1 Yen” and sales of “April 5th” “10 Yen” are output to the output device 12. On the other hand, in the case of the output process for the data stored in the storage device 5 by the above-mentioned storage process,
From the storage device 5, "March 25th" sales "10 yen",
When the sales of "10000 yen" on "April 5th" is read,
Both of these are subject to calculation by the date comparison processing unit 3A. The inverse calculation processing unit 42, according to the above-mentioned second rule,
Change "10 yen" to "0.01 yen" and change to "10000 yen"
Is changed to "10 yen".

From the above, the sales of "March 25""0.0"
“1 Yen” and sales of “April 5th” “10 Yen” are output to the output device 12. Furthermore, in the case of the output processing for the data already stored in the storage device 5 without going through the above-mentioned storage processing, when the sales “10 yen” on “April 5” is read, the date comparison processing unit 3A Is not subject to calculation by
It is output to the output device 12 as it is. Meanwhile, "March 25
When the sales of "day" of "10 yen" is read, the date comparison processing unit 3A performs the calculation. The inverse calculation processing unit 42 changes “10 yen” to “0.01 yen” according to the second rule described above.

As a result of the above, sales of "March 25""0.0"
“1 Yen” and sales of “April 5th” “10 Yen” are output to the output device 12. In this way, the operator only needs to enter the date and amount of the sales slip, regardless of before and after the denomination implementation date, without paying attention to the denomination implementation date and its rate, and to get the value after the denomination. You can know the unified amount data.

On the other hand, the processing device 20 or the business application software internally performs various processes by using the data in the storage device 5 unified to the value before the denomination.
Therefore, it is not necessary to be aware of the denomination implementation date and its rate.

FIG. 3 is a flow chart for storing the amount data.
Data consisting of date data (date) and amount data (number) is input by the operator from the input device 11 (S1).

The date comparison processing unit 3A takes in the data through the input data receiving area 8 and sets it in the input work (work area) (S2). As the input work, a predetermined area of a register or a memory included in the CPU constituting the processing device 20 is used.

The date comparison processing unit 3A compares the denomination execution date (date α) read from the date table with the date data (date) in the input work (S3). When date α ≦ date (when the date is after the denomination), the arithmetic processing unit 41
Changes the position of the decimal point of the amount data (number) in the input work according to the designation of the first rule (S4).

If date α> date (if it is before the denomination), step 4 is not executed. The date comparison processing unit 3A stores the data in the input work in the storage device 5 via the storage device delivery area 10 (S5).

The processing of steps 2 and 5 is as follows.
It may be performed by a storage processing unit (not shown). The storage processing unit executes necessary processing for data storage.

FIG. 4 is a money amount data output processing flow.
Data consisting of date data (date) and amount data (number) is read from the storage device (file) 5 (S).
6).

The date comparison processing unit 3A takes in the data through the storage device delivery area 10 and sets it in the display work (work area) (S7). As the display work, a predetermined area of a register or a memory included in the CPU constituting the processing device 20 is used.

The date comparison processing unit 3A compares the denomination execution date (date β) read from the date table with the date data (date) in the display work (S8). In the case of date β ≧ date (when the date is before the denomination), the inverse calculation processing unit 4
2 changes the position of the decimal point of the amount data (numerical value) in the display work according to the designation of the second rule (S9).

If date β <date (when the date is after the denomination), step 9 is not executed. The date comparison processing unit 3A stores the data in the display work in the storage device 5 via the storage device delivery area 10 (S10).

The processing of steps 7 and 10 may be performed by a display processing unit (not shown).
The display processing unit executes necessary processing for displaying data.

If the read data is the data saved in the storage device 5 by the saving process, the data on the date after the denomination is checked by the flag added to the date data in the display work in step 8. Step 9 is also executed.

Further, when the data set in the display work is the data input from the input device 11, the data before the denomination is the target of the process of step 9 in step 8, and the data after the denomination is step 9.
Is omitted.

The present invention has been described above with reference to the embodiments.
The present invention can be variously modified without changing the gist thereof. In the above-described embodiment, the inside of the processing device 20 is based on the value hit before the denomination and the output is based on the value hit after the denomination (referred to as the first case), but in any case, it is based on the value hit after the denomination (the first). 2). This is suitable when inputting data before the denomination into a system started after the denomination.

The first case and the second case described above may be switched according to the instruction of the operator as needed. Further, regardless of whether the first case or the second case described above is followed (or switched), both the amount data before and after the change may be stored in the storage device 5. In the case of the first case, the amount data before the change is used for the processing in the processing device 20, and the amount data after the change is used for the display.

Furthermore, the present invention can be applied not only to the case where the denomination is carried out but also to the time sale in a department store or the like. In this case, the time table 6 is data for discriminating a specific time zone as the reference time, that is,
Two reference times, the start time and the end time of the time sale, are stored. The time comparison processing unit 3 determines whether the (input) time (time) data of the sales slip is between the start time and the end time (in time) or in other cases (out of time). To determine. Based on this, the arithmetic processing unit 4
1. The process by the inverse calculation processing unit 42 is executed.

For example, when a product with a list price of 1000 yen is sold at 700 yen by time sale, if "1000 yen" is entered, "1000 yen" is stored in the storage device 5 and "700 yen" is stored in the output device 12. Is output. In this case, it is desirable to store both the amount-of-hours data “700 yen” and the amount-of-hours data “1000 yen” in the storage device 5.

In this case, the terminal number of the input device 11 may be designated so that the arithmetic processing unit 41 or the like processes only the input data from the input device 11 having the terminal number. This is suitable, for example, when a time sale is performed only in a predetermined sales floor.

The terminal number is held by the time comparison processing section 3, for example. The terminal number is set in advance by the operator prior to the time sale or the like. The time comparison processing unit 3 performs the following processing of time data comparison processing only on the input data from the input device 11 having the designated terminal number.

Further, in this case, a plurality of terminal numbers may be designated and different calculation rules may be set for each terminal number. This can be applied, for example, when the contents of the time sale are different, such as 30% off at one sales floor and 5% off at another sales floor. In such a case, the calculation rule table 7
In addition, you may hold | maintain as a calculation rule in the form of the table which matched the terminal number and its rule.

[0071]

As described above, according to the present invention,
In the process of changing the amount data, by setting the reference time and the rule for the change in advance, even if the value of the amount data is changed, it can be handled uniformly under the same standard. In such a case, in the processing apparatus, the value before the denomination is treated as a standard, and when the output is performed, the value after the denomination is uniformly output as a reference. Therefore, even if the value of money data is changed, the operator does not need to be aware of the date and the rate of change, and the processing device can continue the work while maintaining the continuity of the data.
