Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to correction processing of data once registered, and is applied to sales data processing devices and the like.

[Summary of the invention] The present invention provides a method for registering sales data.
The correction data corresponding to this sales data, the address of the memory where the sales data to be corrected above have been accumulated, and the arithmetic instructions for correction are created and stored in advance, and if there is a correction instruction, these data are read out. The correction process is performed based on the information.

[Prior art] Generally, when correcting sales data,
As described in Publication No. 266377, a correction process is performed in which data to be corrected is subtracted from sales data that has been added to the total in a previously executed registration process. However, if there are various types of registration processing, such as single item registration, repeat registration, multiplication registration, etc., it is necessary to record the actual procedure of the registration process with the expectation that it will be corrected later. It is necessary to set or clear the flag information shown during each processing operation.
Furthermore, in the correction process, various processes are executed based on the flag information that has been set or canceled, corresponding to various previously executed registration processes.

[Problems to be solved by the invention] However, because of this, the design of the registration processing operation itself becomes very complicated, and the registration processing procedure affects the correction processing, so the correction processing is not performed at the time of designing the registration processing. The design had to take these factors into consideration, making it extremely complex.

Further, in the correction processing, a processing operation for detecting the setting or cancellation of flag information is required, and since it is necessary to execute various corrections, the correction processing program becomes large and its design is complicated. Furthermore, since it is extremely difficult to modify such a complex and large program, it has not been possible to respond to subsequent changes in the operating procedures for correction.

The present invention has been made against the background of the above-mentioned circumstances, and its purpose is to simplify the process of correcting sales data once registered by separating a processing program for correction from a processing program for inputting data. To provide a sales data processing device which does not cause errors in correction because it also sets the memory address where the sales data to be corrected has been accumulated as one of the correction data.

[Means for Solving the Problems] The present invention includes an input means 1 for inputting sales data, etc., a total data storage means 13 for storing total data by category of input sales data, and a total data storage means 13 for storing total data by category of input sales data. correction information storage means 19 for storing correction data corresponding to the sales data input into the input means, an address of the total data storage means in which the input sales data are accumulated, and an arithmetic instruction to be executed at the time of correction; When the instruction is input, the above correction data, the above address, and the above calculation instruction are read out, and the above calculation based on the correction data is performed on the total data in the total data storage means specified by the above address. It is provided with various means of arithmetic means 9 for performing a correction operation according to an instruction.

Incidentally, the reference numerals of the above-mentioned means indicate respective structures in the embodiment corresponding to the above-mentioned respective means.

[Function] When sales data is input by the input means,
The total data by category of the input sales data is stored in the total data storage means, and the correction data corresponding to the input sales data and the address of the total data storage means where the input sales data are accumulated are stored and executed at the time of correction. The arithmetic instruction to be executed is stored in the correction information storage means.

When a correction instruction is input from the input means, the calculation means reads the correction data, address, and calculation instruction from the correction information storage means, and applies the correction data to the total data in the total data storage means specified by the address. Performs calculations according to the based calculation instructions.

[Example] An example of the present invention will be described in detail below with reference to the drawings.

carried out under the control of

Further, the correction data memory 19 is used to write information for correction, and the display information area 20
a, a printing information area 21a, three calculation information areas 22a, 23a, 24a, three memory address areas 22b, 23b, 24b, and data areas 20b, 21b, 2c. Of these, the display information area 20a is written with data for lighting up the correction symbols and repeat symbols on the display section 25, and the print information area 21a is used for writing data for causing the printing section 26 to print correction symbols on receipts, etc. Sales amount data and sales quantity data for correction are written in the corresponding data areas 20b and 21b, respectively. Also, calculation information areas 22a, 23a,

In addition to the correction symbol, the display section 25 also displays the correction amount, the correction number, the repeat symbol, the amount of input sales data, and the number of pieces.
6, the corresponding correction symbol, amount, department, etc. are printed, and these display and printing are done by CPU9.
This is done based on the control processing of

Next, the operation will be explained with reference to the flowcharts of FIGS. 2 and 3.

First, to enter sales data, enter single items,
There are three methods: repeat input, in which input is repeated for the same product, and multiplication input, in which the unit price is multiplied by the quantity for multiple identical products. For single item input, enter the amount using number key 2 and then operate department key 3. For repeat input, operate number key 2 and department key 3, then repeat department key 3 for as many times as you want to repeat. To input multiplication, input the amount using the number key 2, operate the multiplication key 7, enter the number of sales using the number key, and then press the department key 3.
operate. For each input, each key 2, 3,
A flag is set in the RAM 11 according to the operation of 7, a single item flag is set by operating the numeric key 2, a repeat flag is set by operating the department key 3, and a flag is set by the multiplication key 7.
Each operation sets a multiplication flag.

Then, by operating the departmental key 3, the input processing operation shown in FIG _. ). Now, if a single item of ``150'' yen in the ``01'' category is input, the CPU 9 determines the mode of the single item based on the single item flag data in the RAM 11 (step S ₁ ), and displays ``150 yen'' on the display section 25. (Step S <sub>2</sub> ), and write the correction symbol lighting data in the display information area 20a of the correction data memory 19, and write the amount data of ``150'' yen and the number data of ``1'' in the data area 20b. (Step _S3 ). Next, the printing section 26 prints the department "01" and the amount "150" yen (step S ₄ ).
The correction symbol printing data is written in the print information area 21a of the correction data memory 19, and the amount data of "150" yen and the number data of "1" are written in the data area _21b (step S5).

Next, the CPU 9 writes a cumulative sum of 150 yen to the address of department "01" in the departmental memory 15 of the total data memory 13, and
5 reads the link destination address of the group memory 16, writes a cumulative sum of 150 yen to the link destination address of the group memory 16, and also writes the time zone address corresponding to the current time from the clock circuit 18 as a time. It is read out from the band memory 17, and a cumulative sum of 150 yen is also written to the corresponding address in the time band memory 17 (step _S6 ).
In conjunction with this, the CPU 9 writes subtraction instruction data to each of the calculation information areas 22a, 23a, and 24a of the correction data memory 19, and writes the sales data of 150 yen to the memory address areas 22b and 23b, respectively. Write each address of separate memory 15, group memory 16, time zone memory 17, and data area 2.
The amount data of "150" yen and the number data of "1" are written in 2c (step _S7 ). In this way, the single item sales data input process is completed. in this case,
By operating department key 3 of "01", the flag data in RAM 11 is switched from single item to repeat, and if the next key operated is numeric key 2, different sales data will be input. The flag data is cleared, but if the department key 3 is "01", the repeat process described below is performed.

That is, by repeatedly operating the department key 3 of "01", the CPU 9 determines the repeat mode based on the repeat flag data in the RAM 11 (step S ₁ ), and displays the amount of "150" yen on the display section 25. The number of sales "2" corresponding to the number of repeats is displayed (step S ₈ ), and the correction symbol and repeat symbol lighting data are written in the display information area 20a, and the amount data of "150" yen and the number of repeats are written in the data area 20b. The corresponding number data of "2" pieces is written (step _S9 ). Then,
After printing the department "01" and the amount of "150" yen in step _S4 above, the printing section 26 repeatedly prints it (step _S10 ), and writes the correction symbol printing data in the print information area 21a, and also writes the data in the data area. The amount data of "150" yen and the number data of "2" pieces corresponding to the number of repeats are written in 21b (step _S11 ).

Next, the CPU 9 repeatedly writes a cumulative sum of 150 yen to the same addresses of the departmental memory 15, group memory 16, and time zone memory 17 that were written in step _S6 (step S12 ₎ . ), calculation information areas 22a, 23
a, 24a and memory address area 22b, 2
The contents of 3b and 24b remain unchanged, and the amount data of ``150'' yen and the number data of ``2'' corresponding to the number of repeats are written in the contents of data area 22c (step _S13 ). In this way, repeat input processing of sales data is performed, and each time the departmental key 3 is operated, the operations of steps _S1 , _S8 to _S13 are repeated, and each data area 20b, 21b, 22c is
The number data according to the number of repeats is "3",
It is rewritten as "4"...

Furthermore, when there is a multiplication input for three "150" yen in the "01" category, the CPU 9 determines the multiplication mode based on the multiplication flag data in the RAM 11 (step S ₁ ), and calculates "150 yen x 3 = 450". Calculating unit 1 multiplies “yen”
0 (step _S14 ), and the unit price "150" yen is printed on the printing section 26 (step _S15 ). then
The CPU 9 causes the display unit 25 to display the multiplication amount "450" yen (step _S16 ), writes the correction symbol data in the display information area 20a, and writes the multiplication amount data "450" yen and "1" in the data area 20b. Write the number of pieces data (step
_S17 ). In this case, the number of units sold is actually 3 units, but
Since the multiplication amount is input, it becomes one piece. and,
The printing unit 26 prints the division "01" and the multiplied amount of "450" yen (step _S18 ), and prints the printed information area 2.
The correction symbol printing data is written in 1a, and the multiplication amount data of "450" yen and the number data of "1" are written in the data area 21b (step _S19 ).

Next, the CPU 9 stores the departmental memory 15 and group memory 16 in the same manner as in steps S ₆ and S ₁₂ above.
Then, the cumulative total of “450” is written in the time zone memory 17 (step S ₂₀ ), and the calculation information area 22 is
Each memory 1 in which the subtraction instruction data was written to a, 23a, and 24a, and the sales data of ``450'' yen was written to the memory address areas 22b, 23b, and 24b.
Addresses 5, 16, and 17 are stored in data area 2.
The multiplication amount data of "450" yen and the number data of "1" are written in 2c (step _S21 ). When the multiplied sales data input process is completed and the department key 3 is further operated, the repeat input process of steps S ₈ to _{S 13} is performed, and each data area 20
The number data of b, 21b, 22c is "2", "3"
..., and the multiplication amount data of "450" yen is repeatedly input.

In this way, when registering sales data in the total data memory 13 (steps S ₆ , S ₁₂ , S ₂₀ ), correction calculation command data and the address of the sales data to be corrected in the total data memory are also stored. and correction data are also set (steps _S7 , _S13 , _S21 ).

Next, referring to the flowchart in Figure 3,
The operation of correction processing of sales data once registered will be described based on the flowchart shown in the figure. Now, let us make a correction to the single item input of "150" yen mentioned above.

By operating the correction key 6, the correction processing operation shown in FIG. 3 is started, and the CPU 9 stores the correction data memory 1.
9 display information area 20a and data area 20b
The corrected symbol lighting data and the amount data of "150" yen are read from (step T ₁ ), and the corrected symbol and corrected amount "150" are displayed on the display section 9 (step T ₂ ). Next, the CPU 9 reads the print information area 21a and the data area 2 of the correction data memory 19.
The corrected symbol print data and the amount data of "150" yen are read from 1b (step T ₃ ), and the corrected symbol and corrected amount "150" are displayed on the printing section 26 (step T ₄ ).

Next, the CPU 9 uses the calculation information area 22a, memory address area 22b, and data area 22c of the correction data memory 19 to obtain the subtraction instruction data, the address of the department "01" in the departmental memory, the amount data "150" and the amount data "1". 150 yen _x 1 =
150 yen" (step T ₆ ), and it is determined whether the correction processing has been completed (step T ₇ ), since correction processing for group memory 16 and time zone memory 17 still remains. Step T ₅
Return to Then, the subtraction process of "150 yen x 1 = 150 yen" is performed for the total data of the corresponding address in the group memory 16 and the time zone memory 17 (steps _T5 to _T7 ). In this case, since the correction process is performed for the time zone address at the time of input based on the address of the memory address 24b, even if the time zone at the time of correction deviates from the time zone at the time of input, erroneous correction will not be performed.

In addition, when making corrections after repeat input, if the number of repeats is 2, the number data is "2", so a subtraction process of "150 yen x 2 = 300 yen" is performed (step T ₆ ) and the repeat symbol are also displayed (step T ₂ ). In the case of correction after inputting the multiplication, according to the above example, the multiplication amount for 3 products of 150 is already set to 450 yen. "450 yen x 1 = 450 yen" is subtracted from the sum (step T ₆ ), and "450 yen" is displayed and printed (steps T ₂ , T ₄ ).

In this way, the entire program becomes simple as shown in FIGS. 2 and 3, and since each program for input processing and correction processing can be separated, only small changes are required when modifying the program.

Note that when there is no normal sales and a refund is made due to returned goods, subtraction processing is performed on the total data memory 13 during input processing (steps S ₆ , S ₁₂ , S ₂₀ ).
At the same time, addition instruction data is written to the operation information areas 22a, 23a, and 24a of the correction data memory 19 (steps S ₇ , S ₁₃ , and S ₂₁ ), and when the return input is corrected, addition processing is performed (step
T ₆ ) It will happen.

In addition, although only one correction data memory 19 was provided in the above embodiment, a plurality of correction data memories 19 are provided, and correction data is sequentially set for several pieces of input sales data. You may also be able to make corrections.

[Effects of the Invention] As described above, the sales data processing device of the present invention stores various correction data corresponding to the sales data in advance during the registration process of sales data, and if there is a correction instruction, the sales data processing device of the present invention stores the various correction data in advance. Since the data is read and corrected, the processing program for correction and the processing program for input are separated, which greatly simplifies the process, speeding up the correction process, and storing microprograms. In addition, since the program is simplified, it is easier to change the program, and the memory address where the sales data to be corrected is accumulated is also set as one of the correction data, making the correction process easier. When doing so, you will not accidentally correct data at another address,
Furthermore, since the correction data is stored in advance, there is no need to take the trouble to input the correction amount when making a correction, and the correction process can be performed immediately by simply operating the correction key, which provides various effects.
