Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention collects sales data of each sales product cumulatively registered in a sales summary file for all products or for a group specified. The present invention relates to an electronic cash register that can select and output a predetermined number of best data or worst data for a product.

[Prior Art] An electronic cash register stores product data such as product name, unit price, and sales for each item code (product code) that identifies each product in its internal storage for all products sold at this sales floor. Some products have a sales summary file that stores sales data such as points and sales amounts. In such an electronic cash register, for example, if you manually enter the item code, number of sales items, sales amount, etc. of a sales item from the keyboard, the input sales item number and sales amount will be calculated as the sales corresponding to the corresponding item code in the sales summary file. It will be added to the points and sales amount.

Then, when performing inspection work or settlement work, it is possible to print out the number of sales items and sales amount for each product cumulatively registered in the sales summary file as an inspection report or settlement report.

Furthermore, some electronic cash registers with built-in sales tally files contain sales data such as the number of sales items and sales amounts for all the products mentioned above as an inspection report or a settlement report during the inspection or settlement operations. There is a data selection process that not only prints out, but also prints out, for example, only 10 pieces of sales data in descending order of sales items or sales amount, along with item codes and product names. In this way, it is possible to easily grasp the best-selling product group and the least-selling product group at that time, making it possible to carry out quick sales planning and accurate inventory management.

[Problems to be Solved by the Invention] However, even in the electronic cash register that prints out the best data report or the worst data report for all products as described above, there are the following problems. That is, for a store that sells many types of products, it is necessary to divide each product into several groups and understand which products within each group sell well or poorly. However, if a sales plan is drawn up according to the best data report or the worst total report for all products as described above, there is a problem in that the store will have only a biased variety of products, making the store as a whole unbalanced.

The present invention has been made based on these circumstances, and its purpose is to enable selection of a predetermined number of best data or worst data for all products, and to select the best data within a specified group. Alternatively, by making it possible to select the worst data, it is possible to grasp the sales situation in more detail, and to provide an electronic cash register that allows more detailed inventory management and sales plans to be drawn up.

[Means for Solving the Problems] As shown in FIG.
and sales score 3. A sales aggregation file 5 is provided to store each sales data such as sales amount 4, and the sales number 6 and sales amount 7 of each product are cumulatively registered in the sales number 3 and sales amount 4 corresponding to the corresponding product in the sales aggregation file 5. In the electronic cash register, all the products 1 stored in the sales total file 5 are selected by the total sales data selection means 8.
Select a predetermined number of sales data 3 and 4 for each item in ascending order or descending order, and use group sales data selection means 9 to select a predetermined number of sales data 3 and 4 stored in the sales summary file 5. A predetermined number of sales data 3 and 4 of each product belonging to the selected group 2 are selected in ascending order or descending order. Then, the sales data output means 10 outputs the sales data 3 and 4 selected by the selection means 8 and 9 in descending order or descending order.

[Operation] In the electronic cash register configured as described above, the number of sales and sales amount of each product sold at the electronic cash register are added to the number of sales and sales amount of the corresponding product in the sales total file. Then, the total sales data selection means selects a predetermined number of each sales data cumulatively registered in the sales total file in ascending order or descending order. Further, if a group is designated from outside, the group sales data selection means selects a predetermined number of sales data of each product belonging to the designated group in ascending order or descending order. Then, the sales data selected by each of the selection means are output in descending order or ascending order. therefore,
Best data or worst data for all products and best data or worst data within a specified group can be quickly obtained.

A sales summary file R1 is formed in the RAM 30 as shown in FIG. In the sales summary file R1, for each item code that identifies the dish for all dishes (products) sold at this restaurant, the group number 2 of the group to which this dish belongs, such as special information such as discount, sold out, etc. Each product data such as the status, product name (cooking name), unit price, etc., and each sales data such as the number of sales items, sales/amount, etc. are stored. In this example, the groups are formed by five groups numbered 1 to 5, and the item codes are 20 consecutive items from [00011 to [00201]. That is, this restaurant offers (sells) 20 types of dishes (products).

Furthermore, in the RAM 30, as shown in FIG.
A work memory R2 that stores, for example, five item codes read from the sales total file R1, an item code counter R3 that counts the item code A of the sales total file R1, and a memory 1 that stores each item code of the work memory R2. A region number counter R4 counts the region number B of each region of 5 to 5, and a group number corresponding to one item code newly read from the sales summary file R1.

Comparison data memory R5 stores each data DA of status 9 product name, unit price, number of sales items, and sales amount.Sales summary file corresponding to the item code of area number B specified by count value B of area number counter R4 in work memory R2 A comparison data memory R6 that stores each data DB of R1, and an area number counter R4 of the work memory R2 as well.

Assume that as a result of performing normal sales registration work, each data item is totaled in the sales total file R1. In this state, the CPU 25 is programmed to execute the inspection process shown in FIG.

That is, when the flowchart is started, control key 2 is pressed.
4 is confirmed to be set to the [inspection] business mode, the system waits for a combination key operation of the numeric key 19 and the subtotal key 21. When the combination key operation is performed, the number X entered using the number key 19 is determined to be group designation data, and the number
ys in the group designation memory R8. In addition,
If the numerical data entered using the number key 19 is [01], it is assumed that no group has been specified, and data selection processing is executed for all products.

Subsequently, when the combination key operation of the number key 19 and deposit/account key 20 is performed, the number Y entered is determined to be the number of data BM to be printed out as the best or worst data report, and the number of selected data is determined. Store in memory R9. When the above initial condition setting process is completed, data selection process shown in FIG. 9 is started at Pl.

In this embodiment, the sales data to be compared is the number of sales points, and the data are selected in descending order of the number of sales points.

In FIG. 9, when the data selection process is started, the item codes in each area of the work memory R2 of the RAM 30 are first cleared to O, and the count value A of the item code counter R3 is cleared. Then, at P2, 1 is added to the count value A of the item code counter R3, and the item code indicated by the added count value A and the aforementioned sales number of this item code are obtained.

All data including sales amounts are read from the sales total file R1 and stored in the comparison data memory R6. and,
It is confirmed that the item code in the data DB of the stored comparison data memory R6 does not exceed the final item code A. Also, confirm that there is a group specification in P3,
It is checked whether the group number G of the data DB stored in the comparison data memory R6 is the designated group number aS. If the group number G is different from the designated group number aS, the process returns to P2, the count value A of the item code counter R3 is incremented by 1, and the data of the next item code is read. Note that if there is no group designation, it is naturally unnecessary to compare and consider the group number G.

When the group numbers G match, the count value B of the area number counter R4, which specifies the area of the work memory R2, is set to the initial value 1. Then, the item code AB of the data DB of the comparison data memory R6 is stored in the area specified by this area number B in the work memory R2. Next, the count value A of the item code counter R3 is incremented by 1, and all the above-mentioned data of the increased item code A are read out from the sales total file R1 and stored in another comparison data memory R5.

At P4, the sales numbers pA and pB of all the data DA and DB stored in the comparison data memories R5 and R6 are taken out and compared. Then, at P5, sales points PA+
If pB are equal, the item codes stored in each area starting from the next area number B in the work memory R2 are shifted downward one area at a time. In addition, if the sales number PA of the comparison data memory R5 newly stored in P6 is larger than the sales number PB of the item code of the area number B of the work memory R2, then the area number B of the work memory R2 is
The item codes stored in each subsequent area are shifted downward one area at a time. Therefore, the item code of the data DA stored in the comparison data memory R5 is stored in the area of area number B of the work memory R2 which has become empty at P7.

At the same time, this item code is stored in item code memory R7.

On the other hand, if the sales number PB in the comparison data memory R6 is larger than the sales number PA in the comparison data memory R5 at P6, the item code of the sales number PA newly read from the sales total file R1 is stored in the work memory R2. Since it is necessary to store in the area below area number B, increase the count value B of area number counter R4 by 1, and make sure that the increased count value B does not exceed the selection number BM of the data selection number memory R9. After that, the item code AB of area number B in the work memory R2 is stored in the item code memory R7. Then, in P8, check the item code AB in the item code memory R7, and if the item code AB is not O,
That is, if the item code is stored in the next area of the work memory R2, all data corresponding to that item code is stored in the comparison data memory R6 and the process returns to P4. and,
Compare sales points PA and pB.

Also, at P8, the item code in item code memory R7 is set to O.
In the case of , that is, if the item code is not yet stored in the next area of work memory R2, the process advances to P7 and the item code of data DA newly read from sales summary file R1 and stored in comparison data memory R5 is The code is stored in the area number B of work memory R2 and item code memory R7. With the above process, the process of storing one item code in the predetermined area in the work memory R2 is completed.

After confirming that the item code in the item code memory R7 is not 0 in P9, the count value A of the item code counter R3 is increased in the processing after PIO, and the next item code belonging to the same group number G from within the sales summary file R1 is All item code data is read out and stored in comparison data memory R5. At pH, all data DB corresponding to the item code of area number B in work memory R2 are stored in comparison data memory R6. Then, in the same manner as described above, the process returns to P4, and the sales number PA of the data DA is compared with the sales number PB of the data DB.

Then, in P9, if the item code AB read from the sales summary file R1 and stored in the comparison data memory R5 and further stored in the area number B of the work memory R2 becomes O, the corresponding item code of the sales summary file R1 is Since the search for all item codes of the group has been completed, this data selection process is ended.

Then, the printout process of PI3 in FIG. 8 is executed.

In the printout process, the 8M item codes stored in the work memory R2 and the name of each item with the number of sales items corresponding to each item code are printed out as a best data report along with the ranking from 1 to BM.

In the electronic cash register configured as described above, it is assumed that, for example, in the registration process, the number of sales items and the amount of sales are totaled for each item code in the sales total file R1 as shown in FIG.

Next, a case will be described in which the top five sales items of each product belonging to group 1 are selected and printed out in descending order. First, as shown in FIG.
Enter the group number of [1] and the number of data of [5].

Then, the item codes corresponding to group number 1 in the sales total file R1 are sequentially read out in ascending order and stored in each area of the work memory R2 as shown in FIGS. 10(a) to 10(h). That is, in Figure (a), the first item code [0001] is stored in the area with area number B-1, and in Figure (b), this item code [0001] is stored in the area with area number B-1.
0011 Sale” 2 items 2 and the next item code [0002]
The sales score of 4 is compared. And item code [0
002] has a larger sales number, so the item code [002] is larger.
002] is stored in the area above the item code [00011. Similarly, the next item code in the same group is [00
Since the sales score of 8 for [04] is greater than the previous sales score of 2.4, this item code [000
4] in the first area and save the previous item code [000
2] Shift [0001] downward one area at a time.

Furthermore, in FIG. 3(d), the newly read item code [0005] has a sales number of 3, which corresponds to the third among the sales numbers of the previously read item codes, so the number of sales points in the work memory R2 is 3. Store in the th area. Using a similar method, the sales points of all item codes of group number 1 in the sales total file R1 are compared and stored in the work memory R2 in descending order. And finally the same figure (h)
The order is as follows. Incidentally, the sixth and subsequent rankings are naturally not stored in the work memory R2.

Then, when the top five item codes are selected, the 11th
As shown in the figure, the top five rankings include item code, item name,
The number of sales items is printed out on the receipt and issued as a best data report.

In addition, if you want to obtain the best data report for all sales points without specifying a group, use the flowchart in Figure 8.
If the group number is set to [0] and a key is operated, in the data selection process shown in FIG. 9, the item codes in the sales total file R1 are read out in order regardless of the group number and compared in size.

Therefore, the best data report in FIG. 11 is the best data report for all dishes (products).

In this way, the best data report for all dishes (products) can be obtained, and if necessary, the best data report for a specific group can also be obtained with a simple operation. Therefore, it is possible to immediately know which dishes (products) are selling well, and it is possible to manage inventory more appropriately and formulate sales plans more quickly.

In the embodiment, a case is shown in which the best data that sells well is selected, but it is also possible to select the worst data that sells poorly by modifying the flowchart of FIG. Furthermore, the number of data to be selected as the best data or the worst data can be arbitrarily specified by the operator using the keyboard.

Further, in the embodiment, an electronic cash register installed in a restaurant has been described, but it is easy to apply the present invention to an electronic cash register installed in a general store.

[Effects of the Invention] As explained above, according to the present invention, it is possible to select a predetermined number of best data or worst data for all products, and it is also possible to select best data or worst data within a specified group. ing. Therefore, a more detailed sales status can be grasped, and more precise inventory management and a faster sales plan can be formulated.
