Abstract

PURPOSE:To reduce the storing capacity of an RAM which stores the data on articles, by storing the information fed from a keyboard in a storing region of the RAM, and then reading and printing successively the storing contents of the RAM when a report is produced. CONSTITUTION:An ROM3 and an RAM4 are connected to a CPU2, and a working program is stored in the ROM3. The CPU2 works on the basis of the working program. The RAM4 includes a region 41 which stores the article codes, the quantity of sale, the amount of sale, etc. which are fed from a keyboard 5. The region 41 includes a region 411 which stores the sales quantity and the total sales amount of articles for each article code. In the region 411, 10 bytes, for example, are allotted for the storage of one item of the articles of the same attribute on the basis of the same article, and the sales quantity and the total sales amount are stored in the region equivalent to one item for the article corresponding to the article code. Then the CPU2 reads successively the storing contents of the RAM4 and then prints them through a printer 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sales product data registration device, and more particularly, to an improvement of a sales product data registration device that stores data on registered products and later creates the data on the products as a report. Regarding.

In a sales product data registration device such as an electronic cash register (ECR), input product data is temporarily stored in a memory. Then, this stored product data is read out, for example, after the store has closed on the 1st, and a report is created. By the way, in a product data storage memory used in a conventional sales product data registration device, storage areas are fixedly determined in advance to store various product data (sales quantity, price, etc.) for each product code representing the attributes of the product. There are usually hundreds of product codes,
Therefore, the memory capacity becomes large. Also,
In the conventional sales product data registration device, the contents stored in the memory are read out and all the contents stored in the memory are read out and printed regardless of the report.

FIG. 1 is a diagram showing an example of a report created by a conventional sales product data registration device. Report 1 prints the product name, sales quantity, and sales amount for each product code. As mentioned above, this report 1 also includes the sales volume and sales amount of products that did not sell (diesel oil, kerosene, etc.).
is printed as . Therefore, even though there are only a few items for sold products, the items printed in the report are always the number of all product codes, making the report difficult to read.

Moreover, report paper is wasted.

Therefore, the main object of the present invention is to provide a sales product data registration device that can reduce the storage capacity of storage means for storing product data and can create easy-to-read reports.

To summarize, the present invention provides a storage means including a plurality of storage areas for storing at least attributes and cumulative amounts of sales products for different attribute information, and stores attribute information of sales products stored in the storage means in a predetermined order. In this way, the information inputted by the input means is stored in one storage area of the storage means, and when a report is created, the contents of the storage means are read out in the order in which they are stored and printed. It is.

Hereinafter, this invention will be described in more detail with reference to embodiments shown in the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention.

ROM 3 and RAM 4 are connected to ct'u2. The ROM 3 stores an operating program as shown in FIG. 5, and the CPU 2 operates according to this operating program. Further, the RAM 4 includes a storage area as shown in FIG. 4, for example. Further, a keyboard 5 and a printer 6 are connected to the CPU 2.

FIG. 3 is a key arrangement diagram of the keyboard 5 in FIG. 2. In the figure, a mode key 51 is provided on the keyboard 5. This mode key 51 is a key for selecting a predetermined mode depending on its rotational position. for example,
At the 1tEG position, the registration mode is selected, at the X position, an inspection mode that can be operated by a normal operator is selected, and at the Z position, a payment mode that can be operated only by a specific ordinary person is selected. Further, at the OFF position, the operation of the sales product data registration device is stopped. Further, a product key 52 is provided on the keyboard 5□. Usually, this product key 52 is assigned to a product that sells particularly well, and its operation generates a predetermined product food. Further, the keyboard 5 is provided with numeric keys 53 for inputting product codes, sales quantities, unit prices, and the like. Furthermore, the keyboard 5 includes an issue key 54 for instructing the issuance of a sales slip, and a report creation key 55 for instructing the creation of a report. A setting key 56 for commanding the import of information input using the product key 52 or numeric keypad 53
will be provided.

FIG. 4 is an illustrative diagram showing the storage area of the RAM 4 in FIG. 2. In the figure, RAM 4 stores the product code and sales quantity input from the keyboard 5.

It includes an area 41 for storing sales amounts and the like. This area 41 includes an area 411 that stores the sales quantity and cumulative sales amount of products for each product code. In the area 411, for example, 10 bytes are allocated to store one item of products with the same product code, that is, the same attributes, and the product code, sales quantity and cumulative sales amount of the corresponding product are stored in that one item. .

Note that the area 411 is cleared in the initial state, and the number of stored items of product data increases each time product data of a different product code is input. At this time, one of the features of this embodiment is that the writing control of the area 411 is performed so that each product code is arranged in order of smallest value or in order of largest value from the beginning of area 411. Also, area 41
includes a miscellaneous area 412. This miscellaneous area 412 stores the sales quantity of the product that is input along with the product code when the product code input from the keyboard 5 matches any of the product codes already stored in the area 411 and when the area 411 is full. and the sales amount are stored regardless of the type of product code. Generally, this miscellaneous area 41
2 often stores data on products that are not selling well. In a retail store that sells only a few items, the area 411 is rarely full, and the miscellaneous area 412
Product data is rarely stored in

Furthermore, +t AtJ14 includes an area 43 in area 411 that stores the final address where product data is stored. For example, as shown in FIG. 4, if product data has been stored up to address A in area 41, area 43 stores this address A. Furthermore, i
tAM 4 includes an area 44 for temporarily storing the product code, sales quantity, and sales amount input from the keyboard 5.

FIG. 5 is a flowchart for explaining the operation of the embodiment of FIG. 2, and particularly shows the product data write control operation in the registration mode. The operation of the embodiment will be described below with reference to FIGS. 2 to 5.

First, as shown in FIG. 4, it is assumed that product data for four items is already stored in the area 41. The operation when product data (product code fo021J, quantity and price of the product) as surrounded by dotted lines in FIG. 4 is input will be described. In this case, the fifth
At step 1 in the figure (abbreviated as S in the figure), data input through the keyboard 5, that is, data surrounded by a dotted line in FIG. 4, is stored in the area 44.

Then, in step 2a, the product code r0021J of area 44 and the first product code r00 of area 411 are
01J is compared. Next, in step 2b, it is determined that the area 411 is not in an unregistered state, that is, that product data is already stored. Normally, there is no product code that is all 0, so if the product code of the first address in area 411 is all 0, it is determined that it is not in an unregistered state, and conversely, if it is all O, it is determined that it is in an unregistered state. .

Next, in step 3, it is determined whether the area 44 is inconsistent with the first product code in the product code area 411;
In step 4, it is determined that the first product code in area 411 is smaller than the product code in area 44. Accordingly, in step 5, the address specifying the product code position in area 411 is incremented by +10, and the next product code [0OO2J position is specified. Next, in step 6, it is determined that the address specifying the updated product code position does not match address A stored in area 43.

After the operation of step 6 described above, the operation of step 2a is performed again, and the product food l0021J in area 44 is
and the second product code of area 411 1'-0002
J is compared. In this case, the second product code in area 411 [0002J is the first product code roooI
Similar to J, the product code for area 44 is "o.

21'', so steps 2b, 3°4.
Operations 5 and 6 are performed.

Next, in step 2a, the product code [
0O21J and the third product code r0 in area 411
015J, and in this case as well, the operations of steps 2b to 6 are repeated as described above.

Next, in step 2, the product code "0" in area 44 is
021'' and the fourth product code in area 411 [70
56J is compared. In this case, since the fourth product code in area 411 is larger than the product code in area 44, it is determined in step 4 whether this is the case. Then, in step 7, the start address of product code r7056J is set as the address for inserting new data. This new data is product data stored in area 44. Next, in step 8, the area 411
It is determined whether there is an empty area. This judgment is
This is done depending on whether the address A stored in the area 43 matches the final address C of the area 411. If they do not match, it is determined that there is a middle 1 area, and if there is a match [7], it is determined that there is no empty area.

In the case of FIG. 4, it is determined that there is an empty area, and in step 9, the product data with the product code [7056, J and below are shifted by 10 bytes in the direction of the final address C in the area 411. By this shift operation, the product code roo
Final address and product code r70 for items containing 15J
A 10-byte empty area is created between the start address of the item containing 56J. That is, in step 9, all data of items including a product code larger than the product code in area 44 is shifted by 10 bytes to create an insertion area for storing the data in area 44.

Next, in step 10, the address of area 43 is +
10 will be given. By this operation, address A stored in area 43 is rewritten to address B. That is, the address of area 43 is rewritten to the final address of the product data stored in area 411 after the data shift. Subsequently, in step 11, the product code, sales quantity, and sales amount of area 44 are stored in the 10-byte insertion area created in step 9. In other words, the product data of area 44 is stored as product code [0015J]. Items including and product code l-7056J
will be inserted between the item containing the .

Next, the operation when no product data is stored in area 411 will be described. In this case, it is determined in step 2b that the area 411 is in an unregistered state, and in step 2c, the product code, sales number phrase, and sales amount of the area 44 are stored within 10 bytes from the start address of the area 411. .

Next, the operation when the product code in area 44 matches any of the product codes already stored in area 411 will be described. In this case, in step 3, it is determined whether the product code in area 44 and the product code in area 411 match. Then, in step 12, the sales quantity and sales amount in the area 44 are added to the item in the area 411 that includes the product code for which the match has been determined.

Next, we will explain the operation when a product code (for example, r7060J) larger than the largest product code (r7056J in FIG. 4) among the product codes in area 411 and the sales quantity and sales amount of that product are entered from the keyboard 5. explain. In this case, steps 2a, 2b
, 3, 4, 5.6 are repeated, and finally, in step 6, it is determined whether the updated address matches address A of area 43. And step 1
3, it is determined whether address A of area 43 and final address C of area 411 match. This determination is to determine whether there is an empty area in area 411. If address A and address C do not match, it is determined that there is an empty area, and if address A and address C match, it is determined that there is an empty area. It is determined that there is no area. If it is determined that there is a vacant area in the area 411, the product code, sales quantity, and sales amount of the area 44 are stored in an area of 10 bytes from the updated specified address of the area 411 in step 14. For example, keyboard 5
When the product code 1-7060J, the sales quantity, and the sales amount of the product are input from , the product data in area 44 is stored between address A and address B in area 411.

On the other hand, if it is determined in step 13 that there is no empty area in area 411, the sales quantity and sales amount of area 44 are added to miscellaneous area 412 in step 15.

Further, even if it is determined in step 8 that there is no empty area in area 411, the sales quantity and sales amount of area 44 are added to miscellaneous area 412 in step 15, as described above.

As described above, only the product data of sold products are stored in the area 41 in descending order of product code.

The stored contents of this area 41 are read out in the stored order and printed by the printer 6, for example, when the report creation key 55 is pressed in the payment mode. At this time,
Areas 41 and 44 of ILAM 4 are cleared, and the start address of area 411 is set in area 43.

FIG. 6 is a diagram showing an example of a report created by the embodiment described above. In this report 60, only product data of sold products are printed. Further, product data is printed in order of product code □. Therefore, the report is very easy to read. Further, such a report 60 does not have any unnecessary items, so it is possible to save on report paper. Note that it is unlikely that all types of products will be sold in one day, for example. Therefore, area 4
11 does not need to have the capacity to store product data for all types of products. Therefore, the storage capacity of the area 411 can be reduced compared to a conventional memory which has a fixed storage area for each product code of all products. Incidentally, even if the area 411 becomes full, the product data is stored in the miscellaneous area 412, and there is no problem in creating a report.

As described above, according to the present invention, the storage means including a plurality of memory IJs for storing at least the attributes and the cumulative amount of sales products is provided for the attribute information fee of different products, and the attribute information of the sales products is stored in a predetermined manner. Storage means so that they are stored in order ＼
Since the writing of data in the storage means is controlled, and the contents of the storage means are read out and printed in the order in which they are stored, the storage capacity of the storage means can be reduced compared to conventional methods, and a report that is very easy to read can be created. I can do it.
