Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a sales data processing apparatus for processing sales data, and a computer-readable recording medium storing a program including instructions for causing a computer to execute such sales data processing operation. .

[0002]

2. Description of the Related Art Sales data processing devices such as electronic cash registers and point-of-sale (POS) terminals are used in various stores.

In such a conventional data processing apparatus, a correction using a mix match table is widely performed as a price correction means in the number processing.

[0004] This mix-match price correction is to correct the price when a specified number is reached, using a flag and a counter based on the link table number of the link destination for each product. For example, a correction is made such that if three pieces of 40 yen are purchased, 100 yen is purchased.

[0005]

However, in such a mix-match price correction method, if the number of purchases larger than the number for which the mix-match is valid is increased to the normal price for the number more than the number of mix-matches applied. I will return. For example, if one purchases four items of 40 yen each, the total is 140 yen at 100 yen + 40 yen.

Further, price correction in which the discount amount changes stepwise as the number of purchases increases cannot be realized.

[0007] An object of the present invention is to make it possible to create a step-by-step price system that cannot be handled by mix-matching, thereby improving customer service.

[0008]

Means of the present invention are as follows. In the table, unit price change data for each number for changing the unit price according to the number is set in advance for each unit price. The reading means reads the unit price change data from the table according to the registered unit price and the number. The sales data calculation output means obtains sales data based on the unit price change data read by the reading means, and outputs the obtained sales data.

The means of the invention according to claim 8 is as follows. The computer-readable recording medium stores a program for causing the computer to realize the following functions. The first function is a function of reading unit price change data according to a registered unit price and the number from a table in which unit price change data for each unit for changing the unit price according to the unit number is changed according to the number. . The second function is to obtain sales data based on the unit price change data read by the reading means, and to output the obtained sales data.

The operation of the means of the present invention is as follows. Each unit has a table in which unit price change data for each unit for changing the unit price according to the unit is set, and sales data is obtained according to the registered unit price and unit. Therefore, it is possible to create a step-by-step price system that cannot be handled by a mix match, and it is possible to improve customer service.

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIGS.

FIG. 1A is a diagram showing a configuration of an electronic cash register as an embodiment of a sales data processing device according to the present invention. Referring to FIG.
A central processing unit that controls the overall operation of the electronic cash register according to various programs loaded in the RAM 12. The storage device 14 includes a storage medium 16 in which an operating system, various application programs, data files, character font data, and the like are stored in advance, and a drive system thereof. This storage medium 1
Numeral 6 is a fixedly provided or detachably mountable floppy disk, hard disk,
It is composed of a magnetic / optical storage medium such as an optical disk and a RAM card, and a semiconductor memory. Further, programs and data in the storage medium 16 may be stored in a CP
It is loaded into the RAM 12 under the control of U10. Further, the CPU 10 receives programs and data transmitted from other devices via the communication line 18 or the like and stores them in the storage medium 16 or stored in a storage medium provided in other devices. The used programs and data can be used via the communication line 18 or the like.

An input device 20, a display device 22, a printing device 24, and a drawer 26, which are input / output peripheral devices, are connected to the CPU 10 via a bus line. I do.

Although not shown, the input device 20 includes a numeric keypad for inputting amount data and the number of units sold, a department key operated at the time of product registration, a PLU (price look-up) key, and registration of one transaction. Various keys and a mode switch, which are usually provided, such as a cash / deposit key for closing the key, are provided. The mode switch is set to “REG (registered)”, “X (check)”, “Z” according to the switching position.
(Clearing) mode, and in the REG mode, the CPU 10 captures the sales data input from the input device 20 and causes the display device 22 to display and output the data, or sends the sales data to the printing device 24. Then, a registration process is performed to print the receipt / journal and further update the contents of the sales totalizer in the RAM 12.

The printing device 24 is, for example, a two-unit printer. The CPU 10 prints a receipt / journal on roll paper for receipts and journals every time sales data is registered, and closes processing at the end of registration of one transaction. To open the drawer 26 or cut the receipt paper to issue a sales statement receipt.

FIG. 1B is a diagram showing a main configuration of the RAM 12. The RAM 12 includes a set discount table 12A, a PLU file 12B, a temporary storage memory 12C, a print type setting memory 12D, and a work memory. Various memory areas, such as 12E and a subtotal memory 12F, are allocated.

Here, as shown in FIG. 1C, the set discount table 12A includes a discount table for each unit and for each unit price taking into account the correction amount. In the present embodiment, there are three tables, A table (unit price table of 100 yen), B table (unit price of 120 yen table), and C table table (unit price of 170 yen table).
The discount is set in stages up to 0, but is set so that the discount rate is uniform for 11 or more.

As shown in FIG. 2A, the PLU file 12B includes a record for each PLU number (No.), and each record includes a character such as a product name of the product, a unit price, and a price correction. A flag, a totalizer, and a table number (No.) field are included. Here, the money amount correction flag is for identifying whether or not the price is to be corrected. When "1" is written in the flag, the flag is to be corrected, and when "1" is written. Are not to be corrected. The totalizer is for storing the purchased number of the item and the corrected amount. The table number indicates which of the three discount tables in the set discount table 12A is to be used. In this way, by linking a plurality of products to the same unit price table, the discount table can be used. It is possible to provide each unit price instead of each product, and the table capacity can be reduced.

As shown in FIG. 2B, the temporary storage memory 12C stores, for each discount table and each PLU,
This is to temporarily store the number of registrations this time (that is, the current).

As shown in FIG. 2C, the print type setting memory 12D has five flag areas, one of which is set to "1" by user setting. Here, each flag area corresponds to each of the five print types shown in FIG. That is, a table (set discount table 12A) of the unit price and the amount including the correction for each corresponding number is provided, and when a plurality of corresponding products are purchased, the table will be described in detail later. When the price is corrected by the amount corresponding to (1) and the content is printed on a receipt, a journal or the like, a plurality of printing methods can be considered as shown in FIG. Of these printing methods, a setting in the print type setting memory 12D can be set so that a printing method most suitable for the end user can be obtained, and printing can be performed according to the selected printing method. The setting of this flag is performed, for example, by operating the mode key provided on the input device 20 to set the electronic cash register to the setting mode, displaying a screen for selecting a print type, and specifying and inputting any of these. Then, the contents of the flag in the print type setting memory 12D are changed (the designated flag is set and the previous flag is cleared). FIG. 2D shows an example in which three products with the PLU number 001 are purchased and printed by the batch printing method.

The work memory 12E is a memory area used during various kinds of processing.
Is an area for storing the current subtotal.

Next, the operation of the above configuration will be described. FIG. 3 is a flowchart showing the operation for registering the input sales data in the registration mode in which the mode switch (not shown) of the input device 20 is set to the position of “REG”.

That is, when the registration mode is assumed, the input device 20 waits (step S10). If any key input is made, first, it is determined whether or not the input key is a PLU key (step S10). S12).

When a PLU key is input, its P
It is searched whether or not the record of the LU number is registered in the PLU file 12B (step S14), and if not, the process proceeds to step S18 to perform a normal registration process.

If it is registered in the PLU file 12B, it is determined whether or not the amount correction flag of the record of the PLU number is "0" (step S16). If there is no correction, the process proceeds to step S18 to perform a normal registration process.

That is, the normal unit price is picked up from the unit price field of the record (step S18), and the contents of the subtotal memory 12F are updated according to the unit price and the number (step S20). Thereafter, the PLU number and the number are stored in the temporary storage memory 12C (Step S22).
Then, the unit price picked up and the temporary storage memory 1
The PLU file 12 is determined based on the number of registrations stored in the 2C.
The number and the amount are registered in the totalizer of the record corresponding to B (step S24).

On the other hand, if it is determined in step S16 that the amount correction flag is "1", the same unit price registration is performed by referring to the table number field of the record and the temporary storage memory 12C. It is determined whether or not it has already been performed (step S26). If the same unit price has not been registered, the unit price is stored in the temporary storage memory 12C as the same unit price data using the current unit price and the number (step S28). That is, the table number and the number are newly registered. If the same unit price has been registered, the same unit price data stored in the temporary storage memory 12C is updated using the current unit price and the number (step S30).

Thereafter, the current number is checked (step S32), the set discount table 12A is searched with the number (step S34), and the corrected unit price is picked up (step S36). Then, the contents of the subtotal memory 12F are updated according to the corrected unit price (step S38). Thereafter, the process proceeds to step S24,
The PLU file 1 is obtained based on the corrected unit price and the registered number stored in the temporary storage memory 12C.
The number and amount are registered in the totalizer of the corresponding record of 2B.

In step S12, PL
If it is determined that the input is not the U key input, it is determined whether the input is a cash / deposit key input for closing the registration for one transaction (step S40). Then, when the cash / deposit key input, that is, the closing is instructed, a closing process described later in detail is performed (step S42). If the key is not tightened, a process corresponding to the input key is performed (step S44).

FIG. 4 is a flowchart showing details of the closing process in step S42.

That is, first, the work memory 1 of the RAM 12
After initializing the counter X provided in 2E to "1" (step S50), the X-th temporary storage data indicated by the value of the counter X is read from the temporary storage memory 12C (step S52). Then, it is determined whether or not the read data is table data (step S5).
4). Here, if the data is table data, the print type is determined with reference to the print type setting memory 12D (step S56), and an output corresponding to the print type is performed as described in detail later (step S56). S58). If the data is not table data, that is, PLU data, the character and unit price corresponding to the PLU number are read from the PLU file 12B, and they are printed and displayed together with the PLU number (step S6).
0).

After execution of step S58 or step S60, the counter X is incremented by "1" (step S62), and it is determined whether or not there is data in the X-th record of the temporary storage memory 12C (step S6).
4) If there is still data, return to step S52 and repeat the above processing.

When the processing has been completed for all data stored in the temporary storage memory 12C, the subtotal stored in the subtotal memory 12F is printed and displayed (step S66). Thereafter, the temporary storage memory 12C, the work memory 12E, and the subtotal memory 12
F is cleared (step S68), and the process returns to the higher-level routine.

The output corresponding to the print type in step S58 is performed as follows.

First, the case of performing printing of the print type in FIG. 2D will be described with reference to the flowchart of FIG.

That is, first, the number registered this time in the corresponding table of the temporary storage memory 12C is searched, and the number m is stored in the work memory 12E (step S58A1).
Then, it is determined whether or not the number m is equal to or more than the maximum value (11 in the example of FIG. 1C) for performing the gradual discount (step S58A2). Here, if the value is equal to or more than the maximum value, 50% OFF is performed in the present embodiment, so that the price obtained by multiplying the value obtained by multiplying one unit price by the number m is printed and displayed as a discount. (Step S58A
3) Return to the upper routine. Thus, for example, = 1
At 1, printing is performed as shown in FIG.

On the other hand, if it is determined that the number m is smaller than the maximum value, then the work memory 12
The counter n provided in E is initialized to "1" (step S58A4). Thereafter, the n-th character and the amount indicated by the value of the counter n are printed and displayed (step S58A5). At this time, the money amount is a value obtained by subtracting the money amount of the corresponding table number n-1 from the money amount of the corresponding table number n.

Thereafter, the counter n is set to "+1".
Then, it is determined whether or not the result exceeds the number m (step S58A7). If not, the process returns to step S58A5, and if it has, the process returns to the upper routine.

By operating as described above, for example,
For product AAA, the unit price is 100 yen,
When n = 1, the unit price is “$ 100” as it is, when n = 2, 180 yen−100 yen = “$ 80”, and n
When = 3, 250 yen−180 yen = “$ 70” is printed and displayed. As a result, printing as shown in FIG. 2D is performed.

FIG. 6 shows a case where printing of the print type shown in FIG. 2D is performed.

That is, first, the number registered this time in the corresponding table of the temporary storage memory 12C is searched, and the number m is stored in the work memory 12E (step S58B1).
Then, it is determined whether or not the number m is equal to or more than the maximum value (11 in the example of FIG. 1C) for performing the gradual discount (step S58B2). Here, if the value is equal to or more than the maximum value, 50% OFF is performed in the present embodiment, so that the price obtained by multiplying the value obtained by multiplying one unit price by the number m is printed and displayed as a discount. (Step S58B
3) Return to the upper routine. Thus, for example, = 1
At 1, printing is performed as shown in FIG.

On the other hand, if it is determined that the number m is smaller than the maximum value, then the work memory 12
The counter n provided in E is initialized to "1" (step S58B4). Thereafter, printing and display of the first character and the amount are performed (step S58B5). At this time, the amount is the first amount in the corresponding table.

Thereafter, it is determined whether or not the value of the counter n is "1" (step S58B6), and if so, the flow proceeds to step S58B8. On the other hand, if the value of the counter n is not “1”, further discount printing and display are performed (step S58B7). At this time, the discount amount is
From the price of the number n of the corresponding table to the number n of the corresponding table
This is a value obtained by subtracting the value obtained by subtracting the amount of −1 from the first amount of money in the corresponding table.

Thereafter, the counter n is set to "+1".
Then, it is determined whether or not the result exceeds the number m (step S58B9). If not, the process returns to step S58B5, and if it has, the process returns to the upper routine.

By operating as described above, for example,
For product AAA, the unit price is 100 yen,
When n = 1, the unit price is “$ 100”, and n
= 2, unit price “$ 100” and 100 yen− (18
0 yen-100 yen) = the discount amount of “$ 20”, and when n = 3, the unit price “$ 100” and 100 yen−
(250 yen-180 yen) = The discount amount of "$ 30"
Will be printed and displayed respectively, as a result,
Printing as shown in FIG. 2D is performed.

FIG. 7 shows a case where printing of the printing type shown in FIG. 2D is performed.

That is, first, the number registered this time in the corresponding table of the temporary storage memory 12C is searched, and the number m is stored in the work memory 12E (step S58C1).
Then, it is determined whether or not the number m is equal to or more than the maximum value (11 in the example of FIG. 1C) for performing the gradual discount (step S58C2). Here, if the value is equal to or more than the maximum value, 50% OFF is performed in the present embodiment, so that the price obtained by multiplying the value obtained by multiplying one unit price by the number m is printed and displayed as a discount. (Step S58C
3) Return to the upper routine. Thus, for example, = 1
At 1, printing is performed as shown in FIG.

On the other hand, if it is determined that the number m is smaller than the maximum value, then the work memory 12
The counter n provided in E is initialized to "1" (step S58C4). Thereafter, printing and display of the n-th character and the amount are performed (step S58C5). At this time, the amount is the first amount in the corresponding table.

Thereafter, the counter n is incremented by "+1".
Then, it is determined whether or not the result exceeds the number m (step S58C7). Here, if the number m has not been exceeded yet, the above step S5
Return to 8C5.

If the value of the counter n exceeds the number m, discount printing and display are performed (step S58C8), and the routine returns to the upper routine. Note that the discount amount in the above-described discount printing and display is a value obtained by subtracting the m-th amount of the corresponding table from the value obtained by multiplying the amount of the first table by the number m.

By operating in this manner, for example,
For product AAA, the unit price is 100 yen,
After the unit price “$ 100” is printed and displayed for each of n = 1 to 3, 100 yen × 3-250 yen = “$ 50” is printed and displayed as the discount amount. As a result, FIG. Printing as shown in FIG. 2D is performed.

When printing of the print type shown in FIG. 2D is performed, the result is as shown in FIG. 8A.

That is, first, the number registered this time in the corresponding table of the temporary storage memory 12C is searched, and the number m is stored in the work memory 12E (step S58D1).
Then, it is determined whether or not the number m is equal to or more than the maximum value (11 in the example of FIG. 1C) for performing the gradual discount (step S58D2). Here, if the value is equal to or more than the maximum value, 50% OFF is performed in the present embodiment, so that the price obtained by multiplying the value obtained by multiplying one unit price by the number m is printed and displayed as a discount. (Step S58D
3) Return to the upper routine. Thus, for example, = 1
At 1, printing is performed as shown in FIG.

On the other hand, if it is determined that the number m is smaller than the maximum value, the number and the amount are printed and displayed in a multiplication format (step S58D4), and the process returns to the upper routine. In the multiplication type printing and display, the number is m stored in the work memory 12E, and the amount is the m-th amount in the corresponding table.

By operating in this manner, for example,
For the product AAA, “3 ×” as the number and “$ 250” as the amount are printed and displayed,
The printing result as shown in FIG. 2D is obtained.

When the printing of the printing type shown in FIG. 2D is performed, the printing is performed as shown in FIG. 8B.

That is, first, the number registered this time in the corresponding table of the temporary storage memory 12C is searched, and the number m is stored in the work memory 12E (step S58E1).
Then, it is determined whether or not the number m is equal to or more than the maximum value (11 in the example of FIG. 1C) for performing the gradual discount (step S58E2). Here, if the value is equal to or more than the maximum value, 50% OFF is performed in the present embodiment, so that the price obtained by multiplying the value obtained by multiplying one unit price by the number m is printed and displayed as a discount. (Step S58E
3) Return to the upper routine. Thus, for example, = 1
At 1, printing is performed as shown in FIG.

On the other hand, if it is determined that the number m is smaller than the maximum value, the number and the amount are printed and displayed in a multiplication format (step S58E4), and the printing and display of the discount amount are performed. After performing (Step S58E
5) Return to the upper routine. Here, in the printing and display in the multiplication format, the number is m stored in the work memory 12E, and the amount is a value obtained by multiplying the first amount in the corresponding table by m. Also, the above discount amount is
This is a value obtained by subtracting the m-th amount of the corresponding table from the value obtained by multiplying the first amount of the corresponding table by m.

By operating as described above, for example,
For the product AAA, the unit price “$ 100” and the quantity “3 ×” and the amount of 100 yen × 3 = “$ 300”, and the discount amount of 100 yen × 3-250 yen = “$ 5”
"0" is printed and displayed, respectively, and a printing result as shown by (D) in FIG. 2 is obtained.

As described above, in the present embodiment,
By providing a table with correction amounts according to the number of pieces, it is possible to create a step-by-step price system that cannot be handled by a mix match. In addition, by providing a table for each unit price, not for each product, a plurality of products can be linked to the same unit price table, so that the table capacity can be reduced. As a result, customer service can be improved.

Further, since it is possible to set whether or not to perform the price correction for each product by the amount correction flag, it is possible to deal with products excluded from discount.

The present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made.

For example, a unit price that changes according to the number includes a surcharge.

Although the discount amount is printed collectively at the time of closing, it may be printed every registration (excluding the print type).

Further, the classification of the goods is not only PLU, but also division,
It may be a part number or a mixture of them.

Further, a discount like a mix match may be added. For example, one commodity AAA for 100 yen (n
1) When one (B2) of the goods BBB of 120 yen is purchased in total (n = n1 + n2), the total amount is n1 pieces amount (100 yen) from the A and B tables of the set discount table 12A. ) + N2 quantity of money (120 yen) = 22
At this time, based on the cheaper table (A table in this case), nx one cheaper amount (2 ×
100 yen)-Discount price of the cheaper n items (180 yen)
= 20 yen can be the discount amount. in this case,
A printing result as shown in FIG. 9A is obtained.

Also, what is stored in the set discount table 12A may be a discount rate according to the number as shown in FIG. 9B. That is, for example, if three products with a unit price of 100 yen are purchased, 100 yen × 3 pieces × 0.83 = 24
It will be 9 yen.

If designation of point discount is preset for each PLU in the PLU file 12B, either one (lower or higher) may be freely selectable (preset, key designation, etc.). For example, as shown in (C) of FIG. 9, when the preset discount is set in the PLU file 12B, the set discount table 12A is ignored and the price is set to 260 yen.

The number of the predetermined discount may be different for each unit price of the set discount table 12A (unit price 100 yen table, unit price 120 yen table,...). For example, in a unit price 100 yen table, 10 or more units can be set to 50% OFF, and in a unit price 500 yen table, five or more units can be set to 50% OFF. Also, the discount rate may be changed (for example, the unit price 100 yen table is the same as the previous example, and the unit price 50 yen).
For example, turn off 5 or more 0 yen tables by 30%).

The discount rate of the set discount table 12A may be changed in the number range as shown in FIG.

[0071]

According to the present invention, a set discount table, which is a unit price table for changing the unit price according to the number of units, is obtained for each unit price, and sales data is obtained according to the registered unit price and the number of units. So that you can create a step-by-step pricing structure that mixmatch cannot handle.

Therefore, customer service can be improved.
