Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a product sales data suitable for performing bulk sale registration for each individual product called a mix and match (hereinafter abbreviated as M & M) system. Regarding a processing device.

[Prior Art] In a supermarket or retail store, when a plurality of designated products are purchased in a lump sum, the sales amount may be discounted to provide services to customers.
It is called a method. In the conventional M & M system, one item was sold for 80 yen, and 3 items were sold for 200 yen.
We will also sell 20 yen carbonated drinks, 100 yen fruit juice drinks and 90 yen dairy products in any combination for 3 pieces at 270 yen, such as bulk selling between different departments, different prices, different products. Is starting to appear. A conventional product sales data processing device capable of processing the M & M method of discounting a plurality of kinds of products having different unit prices when a predetermined number of products are purchased as a mass sale is provided with a total amount memory in an internal storage unit such as a RAM. At the same time, areas for individual unit price, number of sales, amount of sales, number of establishments, number of establishments, and set price were provided as calculation buffers.

Then, when the sale registration of the product is performed, the control unit adds the sales amount of the registered product to the total amount memory and determines whether the registered product is the M & M designated product. Here, in the case of the first registration of the M & M designated product, the M & M preset in the established number area and the set price area is set.
The number of established products and the price of M & M set are stored. Further, the unit price of the registered product is stored in the unit price area, and the sales quantity and the sales amount are respectively stored in the sales quantity area and the sales amount area. On the other hand, in the case of the second and subsequent registration of the M & M designated product, the content of the unit price area is updated to the unit price of the registered product, and the sales quantity and sales price of the registered product are added to the sales quantity area and the sales price area. . Then, if the contents of the sales quantity area match the contents of the established quantity area, it is determined that the collective sale is successful at that time,
The discount amount obtained by subtracting the contents of the set price area from the contents of the sales amount area is subtracted from the total amount memory. In addition, the contents of the number of times of establishment area is set to "+1", and the sales quantity area and the sales amount area are cleared to "0".

Therefore, the discount amount differs depending on the registration order of the M & M designated products.

That is, in the above example, one customer can purchase a carbonated drink of 120 yen.
Book (this is a), one 100 yen fruit juice drink (this is b), two 90 yen dairy products (this is c1,
c2) Suppose you have purchased. In this case, c1, c
If you register in the order of 2, b, a, the bundling will be completed when b is registered, so the discount amount is 280-270.
= 10 yen. On the other hand, if a, b, c1, and c2 are registered in this order, the bulk sale is completed when c1 is registered, and the discount amount is 310-270 = 40 yen. Therefore, the latter is discounted by 30 yen more than the former.

Further, when the registration of the M & M designated product is canceled, the control unit first checks the single product / single price area. If the same unit price information as the unit price of the canceled product is stored, the sales quantity area is checked. If the content of the sales quantity area is not "0", the area is set to "-1" and the unit price of the canceled product is subtracted from the total amount memory and the sales amount area. If the content of the sales quantity area is "0", the establishment frequency area is checked, and if it is not "0", "-1" is added and the unit price of the canceled product is subtracted from the total amount memory. In addition, the unit price of the canceled product is M & M
The M & M set price is subtracted from the result of multiplying the number of established products, and
The discount amount obtained when & M is established is estimated, and the discount amount is added to the total amount memory. On the other hand, if the same unit price information as the unit price of the canceled product is not stored in the single unit price area, immediately check the establishment frequency area,
After confirming that it is not "0" in the same manner as above, add "-1" and subtract the unit price of the canceled product from the total amount memory, and further subtract the M & M set price from the result of multiplying the unit price of the canceled product by the number of M & M completed. The discount amount obtained when M & M was established was estimated, and the discount amount was added to the total amount memory.

Therefore, when the registration of the once-registered M & M designated product is canceled, the discount amount may differ depending on the timing of canceling the product.

That is, in the above example, the customer purchases a carbonated drink of 120 yen for 2
It is assumed that a book (designated as a1 and a2), a 100 yen fruit juice beverage (designated as b), and a 90 yen dairy product (designated as c) are purchased. In this case, a1, a
If registration is made in the order of 2, b, and c, and then b is canceled, the total sale is completed at the time when b is first registered, and the total is 270 yen. Then, when c is registered, the total is 360 yen. Then cancel b and the total will be 260
It becomes a circle, and 100 × 3−270 = 30 yen is further added to obtain 290 yen. That is, 40 yen is discounted by the bulk sale of a1, a2, and c. On the other hand, if you register in the order of a1, a2, b, cancel b here, and then register c, the total sale will be established at the time when b is registered first, so the total will be 270 yen and the discount amount. Is 70 yen. Then, when b is canceled, the total becomes 1
It will be 70 yen, and 100 × 3-270 = 30 yen will be added to make 200 yen. After that, if c is registered, the collective sale will be established again, and the total amount will be 270 yen. That is, in this case, 60 yen is discounted for the same combination of bulk sale products as before.

[Problems to be Solved by the Invention] As described above, in the conventional product sales data processing device, when a predetermined number of plural kinds of products having different unit prices are purchased, the product sale of the M & M method is discounted as a successful sale. In this case, the discount amount was different depending on the registration order, which lacked fairness to the customers and the serviceability was insufficient. Further, when the registration of the registered M & M designated product is canceled, the discount amount may be different depending on the timing of canceling the product.

Therefore, according to the present invention, when a plurality of types of products having different unit prices are purchased in a predetermined number, the discount is determined as a successful sale.
An object of the present invention is to provide a merchandise sales data processing device capable of offering the most convenient discount for customers regardless of the order of registration of merchandise and improving serviceability when adopting the M method.

Another object of the present invention is to provide a merchandise sales data processing device capable of providing sufficient service without causing any disadvantage to the customer due to the difference in the timing of cancellation even if the M & M designated merchandise is deregistered. .

[Means for Solving Problems] The present invention corresponds to the case where at least unit price information is stored in correspondence with a single product code attached to each product and the single product is a bundled product, as shown in FIG. A single product information file F that stores the bundled sales information of the number of bundled products sold and the set price, and a bundled product calculation table that stores a plurality of product information such as a product code, unit price, quantity, and sales amount corresponding to the bundled sales information.

And the product discriminating means A for judging whether or not the bulk sale information is set corresponding to the single product code, and when the discriminating means A confirms the input of the single product code for which the bulk sale information is not set, The normal product registration means B for calculating the sales amount from the unit price information corresponding to the individual product code and the input sales quantity and adding it to the total amount memory W, and the individual product code input of the collective selling information setting by the discriminating means A. When confirmed, the sales amount is calculated from the unit price information corresponding to the unit item code and the input sales amount and added to the total amount memory W, and the set sale item set in the bundle item sale table T. Collective sale product registration means C that stores the individual item code, unit price, sales quantity, and sales amount of the corresponding sale item in descending order of unit price corresponding to the information.
And an end instruction means J for instructing the end of registration of one transaction, and when the end instruction means J is instructed and input, the sales quantity and the sales amount are added in order from the top area of the batch sale product operation table T. , When the sales quantity addition value reaches the corresponding number of bundled sales completed, the corresponding discount price is calculated by subtracting the corresponding set price from the sales amount addition value, and the discount amount calculated by this calculation means D. And a discount processing means E for calculating the total sales amount by subtracting from the total amount in the total amount memory W, and when a predetermined number of a plurality of types of bundled sale products having different unit prices are purchased, a preset set price is set. It is designed to be sold.

In addition to the above-mentioned means, according to the present invention, when registration cancellation of a bulk sale product is designated before the end instruction means J inputs an instruction to end the registration, the bulk sale product operation table T indicates that the bulk sale product is to be registered. Cancellation processing means F for subtracting the sales quantity and sales price corresponding to the single item code by the number of cancellations
Is provided.

[Operation] According to the present invention having such a configuration, when the unit code and the sales quantity of all the products registered for sale in one transaction are input from the input unit, the total amount of all the products is stored in the total amount memory. . Further, in the bundled-sale product calculation table, the unit-item code, unit price, sales quantity, and sales amount of the products designated for bundled sale among all the products are stored in descending order of unit price corresponding to the corresponding bundled-sale information. . 1 in this state
When the end of transaction registration is instructed, the sales quantity and sales price are added in order from the first area of the bundled product calculation table, and when the sales volume addition value reaches the corresponding bundled sales number, the sales amount addition value is used. The set price is reduced to calculate the discount amount, and the discount amount is subtracted from the total amount in the total amount memory to calculate the total sales amount.

Also, if registration cancellation of the bulk sale product is specified before the end of registration is instructed, the sales quantity and the sales amount corresponding to the individual product code of the bulk sale product are the same as the number of cancellations from the bulk sale product calculation table. Is subtracted.

Further, a working area is formed in which the information of the single item code, unit price, quantity, and sales amount of the M & M product for which the corresponding M & M number is set is sequentially stored and sorted in descending order of unit price.

On the other hand, in the set sale item calculation table 42, areas for storing the set sale number, the set sale type, and the set price read from the single item information file 32 of the set sale item are used, and are used in the same meaning as the CAL flag. Flag, a bottom pointer indicating a pointer that stores the final registration information of the working area, which will be described later, and a summary discount amount area that stores the amount of the summary discount calculation result. A working area is formed for sequentially storing information such as the individual item code, set quantity, quantity, and sales amount of the set sale product for which the item is set.

Further, the item buffer 43 is formed with a working area for storing the single item registration information and an input pointer indicating a pointer of the working area for storing the single item registration information.

Therefore, the CPU 1 is configured to operate according to the predetermined input information by the processing program stored in the ROM 4 according to the procedure of the following FIGS. 6 to 11.

FIG. 6 shows a single-item registration processing procedure when the bar-code scanner 8 reads a bar-coded single-item code. As for the method of registering a single item of a sold product, only the single item code is read when only one point is registered, and when two or more points are registered, the sales quantity is entered with the numeric key 21 and then the individual item code is registered. Read. That is, when a single item code is input from the bar code scanner 8, the single item information file is searched based on this single item code, and the status corresponding to the corresponding single item code is set to 0 or 1 as ST1.
Is set, that is, whether it is a bulk sale product (product determination means). If either 0 or 1 is set in the status, S
The status = 1 or 0 is determined as T2. Here, when the status = 0, the single item is an M & M product, so the M & M number of the M & M product calculation table 41 is searched, and is there a table in which the M & M number corresponding to the single product code is set as ST3? Determine whether or not. Then, if it exists, the M & M product operation table 41 is searched for a single product code in the working area, and it is determined in ST4 whether the same code as the single product code is stored. And, if stored, the sales quantity (1) and sales amount (unit price) of the single item in the quantity area and sales amount area of the same code.
Is added, and if the CAL flag 44 is set as ST5, it is reset. Next, in ST6, it is determined whether or not the input pointer of the item buffer 43 has reached the specified value. If not, the contents of the single item information file of the single item are stored at the point indicated by the input pointer and the input pointer is set to " +1 ”is updated. Further, the product sales data is registered in a predetermined PLU file or department file, and the sales amount is added to the main itemizer 48. Further, the information such as the name and the sales amount is displayed on the display device 10, and at the same time, the receipt is printed on the receipt and the journal by the printer 12, and the process is completed.

On the other hand, if the corresponding single item code does not exist in the M & M product calculation table 41 in ST4, it is determined in ST7 whether the number of data in the working area has reached the specified value from the value of the bottom pointer in this table 41. , If it has reached, it is an error. In contrast,
If it has not reached, the unit price of the data already stored in this working area is compared with the unit price of the single item, and the areas are sorted so that the unit prices are in descending order, and the product is displayed in the predetermined area. Unit code, unit price, quantity,
Stores the sales amount. Then, set the bottom pointer to +1
Update and move to ST5.

If there is no M & M product calculation table 41 in which the corresponding M & M number is set in ST3, ST
As 8, it is determined whether or not the M & M counter 45 has reached the specified value, and if it has reached the value, it is judged as an error. On the other hand, when the number has not reached, a table 41 in which an area for forming the M & M product operation table 41 is secured in the RAM 5 and the M & M number, the number of sets, and the set price corresponding to the individual product code are set in this area And the bottom pointer is initialized. After that, the M & M counter 45 is updated by +1 and the process proceeds to ST7. (that's all,
Collective sale product registration means) If the status is 1 in ST2, since the single item is a set sale product, the process proceeds to the set sale process shown in FIG. That is, the set sale number is searched for in the set sale item calculation table 42, and it is determined in ST9 whether or not there is a table in which the set sale number corresponding to the single item code is set. If it exists, the individual item code of the working area in the set sale item operation table 42 is searched, and ST1
It is determined whether or not the same code as the single item code is stored as 0. If it exists, the quantity and sales amount are accumulated in this working area, and ST
If the CAL flag 44 has been set as 12 then it is reset and then ST6 in FIG.
The same process as the following procedure is executed.

On the other hand, in ST10, if the corresponding single item code does not exist in the set sale item operation table 42, it is determined in ST12 whether the number of data in the working area has reached the specified value from the value of the bottom pointer in this table 42. However, if it has reached, an error occurs. On the other hand, if the number has not reached, the item number, set quantity, and
Stores quantity and sales amount. After that, the bottom pointer is updated by +1 and the process proceeds to ST11.

Further, in ST9, if the set sale item operation table 42 in which the corresponding set sale number is set does not exist, it is determined in ST13 whether or not the set sale counter 46 has reached the specified value. And On the other hand, when the number has not reached, an area for forming the set sale item operation table 42 is secured in the RAM 5, and the set sale number, the set sale type, and the set price corresponding to the single item code are set in this area. The table 42 is formed and the bottom pointer is initialized. Then, the M & M counter 45 is updated by +1 and the process proceeds to ST12. In ST1 of FIG. 6, if the single item is not a bulk sale item, the process proceeds to ST6, and the subsequent single item registration process is executed (normal item registration means).

Further, when the minus key 25, for example, is input as the designated cancellation key on the keyboard 6 and then the single item code of the product for which registration cancellation is designated by the numeric keypad 21, the operation is performed according to the procedure shown in FIG. That is, the individual item information sequentially stored in the item buffer 43 in response to the input of a predetermined designated cancellation key is searched, and it is determined in ST14 whether the individual item code of the item for which cancellation is designated is stored. If it is not stored, an error occurs. If it is stored, the single item information of the product for which cancellation is designated is again stored in the pointer indicated by the input pointer of the item buffer 43, and at the same time the input pointer is set to "+1".
Update. Next, as ST15, the item buffer 43
Based on the single item information stored again, it is determined whether the product is a bulk sale product, that is, whether the status is set to 0 or 1. And status = 0
If it is or1, the corresponding calculation tables 41 and 42 are searched, and the contents of the quantity and the sales amount corresponding to the single item code of the product are subtracted by the cancellation amount (cancellation processing means). Here, in ST16, it is determined whether or not the quantity has become “0”, and if it has become “0”, the contents of this working area are erased to sort the table and the bottom pointer is set to “−1”. Update. Further, when the bottom pointer becomes "0" by this, the corresponding counter 4
The count value of 5,46 is decreased.

Then, after the table sort process is completed, or when the quantity does not become "0" due to the subtraction process of the calculation table,
Furthermore, if the product is not a bulk sale product, a predetermined designated cancellation registration process is performed on the PLU file or department file, and the canceled product is displayed and printed, and then the process ends.

Further, when the subtotal key 23 or the deposit / cash total key 24 as the end instruction means for instructing the closing of the registration is operated, the operation is performed in the procedure shown in FIGS. 9 and 10. Subtotal key 23
Is operated, the CAL flag 4 is entered as ST17.
4 is set, and if it is reset, the arithmetic process shown in FIG. 11 is executed, and then RA
The contents of the M5 NET itemizer 49 are displayed on the display unit 10 and the process ends. In ST17, the CAL flag 44
If is set, NET is executed without performing arithmetic processing.
The contents of the itemizer 49 are displayed.

On the other hand, if the deposit / cash total key 24 is operated, ST1
It is determined whether the CAL flag 44 is set as No. 8, and if it is reset, the arithmetic processing shown in FIG.
The contents of 7 are printed on the receipt by the printer 12. If the CAL flag 44 is set in ST18, the calculation processing is not performed and the total discount amount area 47 is set.
Print the contents of the on the receipt. After that, in ST19, it is determined whether or not the deposit closing process is performed based on the presence or absence of the register number data. If there is the register number data, that is, in the case of the deposit closing process, the change calculation is performed and the change amount is displayed on the display 10. At the same time, the total sales amount, the deposit amount, and the change amount are printed on the receipt, and after the predetermined registration processing is performed, the CAL flag 44 is reset, the M & M counter 45 and the set sales counter 46 are cleared, the main itemizer 48 is cleared, Various initializations such as the initialization of the item buffer 43 and the input pointer are performed, and the process ends. If it is not the custody process, the total sales amount is displayed on the display 10 and printed on the receipt, and then the normal registration process and initialization of various information are performed.

The arithmetic processing is performed according to the procedure shown in FIG. First, in ST20, it is determined whether or not the value of the M & M counter 45 is "0", and if it is not "0", the set M & M is set.
The M & M product calculation table 41 with the number A (initial value = 1) is taken out, and the sales amount in the working area is added by the set number set in the table 41 in the order of the pointer, that is, in the order of the unit price. And
If the sales amount is added for each set number, the set price is subtracted from the added amount, and the subtracted amount is stored as a collective discount amount in the collective discount amount area (summary discount amount calculation means). Similarly, the M & M numbers are A + 1 and A +.
2, the M & M product calculation table is taken out, and if the data in the working area is stored in the set number or more, the collective discount amount is calculated and stored.

Then, in ST21, if the collective discount calculation processing is completed for all the M & M product calculation tables 41, it is determined in ST22 whether the value of the set sales counter 46 is "0". If the set sales number is not “0”, the set sales product calculation table 42 with the set set sales number B (initial value = 1) is taken out, and the set sales type set in this table 42 is stored in the working area. If so, add the sales amount. Then, the set price is subtracted from the added amount, and the subtracted amount is stored as a combined discount amount in the combined discount amount area. Similarly, set sales numbers are B + 1 and B +
2, the set sale product calculation table 42 is taken out, and if the contents of the set sale type are established from the data in the working area, the collective discount amount is calculated and stored.

Then, in ST23, when the collective discount amount calculation processing is completed for all the set sale item calculation tables 42, the contents of the combined discount amount areas of the calculation tables 41, 42 are accumulated in the total combined discount amount area 47. Next, the contents of the main itemizer 48 whose total amount is calculated by adding the sales amount of the sale item by the registration process and the contents of the total discount amount area 47 are subtracted, and the result is set as the total sales amount. It is stored in the NET itemizer 49 (discount processing means). After that, the CAL flag 44 is set and the process ends.

In the merchandise sales data processing apparatus of the present embodiment configured as described above, when the single item code of the single item designated as the M & M item is input, the M & M number, the number of sets, and the set price corresponding to the single item are set. The M & M product calculation table 41 stores a single product code, a unit price, a quantity, and a sales amount, and the data is sorted in the table in descending order of unit price. Further, when the single item code of the single item designated for the set sale item is input, the single item code, the set quantity, and the set item number are set in the set sale item operation table 42 in which the set sale number, the set sale type, and the set price corresponding to the single item are set. The quantity and sales amount are stored. Then, when the subtotal key 23 or the deposit / cash total key 24 is operated, the collective discount calculation is performed in each of the calculation tables 41 and 42. That is, in the M & M product calculation table 41, the number of data in the working area is counted in ascending order of points, that is, in the order of increasing unit price, and when the set number is established, the sales amount of these data is added,
The combined discount amount is calculated by subtracting the set price from the added amount. By extracting the data in the working area in ascending order of points from the set sale item calculation table 42, the sales amounts of these data are added when the set sale type is established, and the set price is subtracted from the added amount. A summary discount is calculated. Thus, the summary discount amount of each of the calculation tables 41 and 42 is accumulated in the total summary discount amount area 47, and the main itemizer 4
The total sales amount is calculated by subtracting the total discount amount from the total amount in 8, and displayed on the display unit 10.

As described above, according to the present embodiment, the M & M product calculation table 41 stores the data of the corresponding M & M products in descending order of unit price regardless of the registration order, and according to this storage order, the discount condition as an M & M product. Since it is determined whether or not has been established, no matter which order the M & M items are registered, the discount is given to the bulk sale item having the highest total price. Therefore, the transaction is made at the discount rate that is most convenient for the customer. In addition, since the set sale item calculation table 42 is formed and a predetermined discount can be performed if the condition set for the set sale item is satisfied, it is possible to carry out a transaction designated up to the number of bundle sale items.

Further, the contents of the registered single-item information file are stored in the item buffer 43, and if the registration cancellation of the bulk sale item is designated, the contents of the single-item information file are read from this buffer 43 and the corresponding operation table 41 is read. ，
Since I am trying to correct the contents of the work area 42,
Registration can be canceled accurately regardless of the timing of cancellation, and the discount will not change due to this cancellation. Therefore, the customer can safely specify the cancellation of the product.

The present invention is not limited to the above embodiment.
For example, in the above embodiment, the case where all the contents of the single item information file are registered in the item buffer 43 is shown, but at least only the single item code is registered, and when the registration cancellation is designated, the single item code read from the item buffer 43 is used as the single item code. The information file may be searched and the cancellation processing may be performed. In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, at least unit price information is stored in correspondence with a single product code attached to each product, and when the single product is a bundled product, a corresponding bundled sale is established. In a single transaction, a single item information file that stores the bundled sale information of the number of pieces and the set price, and a bundled sale product calculation table that stores a plurality of item information such as a single item code, unit price, quantity, and sale price corresponding to the bundled sale information. A total price memory that stores the total price of the products to be sold is provided.Each time the individual product code and sales quantity are entered via the input section, the individual product information file is searched with that individual product code and the corresponding individual product code is handled. Then, it is determined whether or not the bulk sale information is set. Then, when the input of the single item code for which the collective sale information is not set is confirmed, the sales amount is calculated from the unit price information corresponding to the single item code and the input sales quantity, and added to the total amount memory, and the collective sale information setting When the input of the single item code is confirmed, the sales amount is calculated from the unit price information corresponding to the single item code and the input sales quantity and added to the total amount memory, and the set summary is set in the bundled product calculation table. Corresponding to the sales information, the unit code, unit price, sales quantity, and sales amount of the corresponding sales product are stored in descending order of unit price. Then 1
When the end of transaction registration is instructed and input, the sales quantity and sales price are added in order from the first area of the bundled sales product calculation table. The corresponding set price is subtracted to calculate the discount amount, and the discount amount is subtracted from the total amount in the total amount memory to calculate the total sales amount.

Therefore, when the M & M method is adopted in which a plurality of types of products with different unit prices are purchased in a predetermined quantity when they are sold together, the discount can be most convenient for the customer regardless of the order in which the products are registered. A product sales data processing device capable of improving serviceability can be provided.

Further, according to the present invention, when the registration cancellation of the bulk sale product is designated, the quantity corresponding to the corresponding product code and the sales amount are subtracted from the bulk sale product operation table. Therefore, the registration cancellation of the M & M designated product can be performed. Even if there is, there is no disadvantage to the customer, and it is possible to provide sufficient service.
