Description

The present invention relates to a product sales data processing device such as an electronic cash register or a POS (point of sale information management) system used in a store.

[Prior Art] Data of each product registered for sale is stored in a memory, for example, by division code or PLU (price lookup).
In a conventional product sales data processing device that collects data by code, it is common to print the registration data on a receipt and a journal every time a product is registered for sales. In addition, it has a buffer to store the code and sales data of the product registered immediately before, and in response to the key operation of the previous cancel key, only the product registered immediately before can be registered for cancellation based on the data in this buffer. Although a product sales data processing device that has made it possible has been put into practical use, the timing of printing on receipts and journals is also in response to the sales registration of products, and cancellation printing is performed if there is a previous cancellation. I am doing it.

[Problems to be Solved by the Invention] However, in an apparatus that prints out registration data of a product in response to a sales registration operation on a receipt and a journal, although there is an advantage that the time from the tightening operation to the receipt issuance is short, When the same product is continuously registered, the registration data of the same product is repeatedly printed on the receipt and the journal, which makes it difficult to see the print content and wastes paper. Since the journal may confirm the registration operation sequence, the registration sequence may need to be printed, but the receipt is for confirming the products purchased by the customer and is required to be simplified and easy to see.

Therefore, according to the present invention, when the same product is continuously registered, the registration data can be collectively printed out as one registration data without delaying the time from the closing operation to the receipt issuance, which is simplified and easy to see. The object is to provide a product sales data processing device that can issue receipts and save paper.

[Means for Solving the Problem] According to the present invention, the sales data of the registered products for sale are totalized in the memory for each code, the printer prints on the receipt and the journal, and the receipt is issued according to the registration closing operation. In the product sales data processing device, it is determined whether or not the registration data buffer that stores the code and sales data of one product that was registered for sale immediately before, and the product that is next registered for sale are the same as the products in the registration data buffer. The product determination means, the sales data update means for adding the sales data obtained when the determination means determines that the products are the same product, and the determination means determine that the products are different products. When the registration is completed or in response to the registration closing operation, the printer prints the data in the registration data buffer on the receipt. And a receipt print control means.

In addition, real-time printing means for printing out the data of the registered goods to the journal in response to the sales registration of the goods, and buffering for printing out the data in the registration data buffer to the journal at the timing of printing on the receipt by the receipt printing control means. It is preferable to include a printing unit and a journal printing selection unit that selects either the real-time printing unit or the buffering printing unit.

[Operation] With the product sales data processing device that takes such a means, the next product is registered for sale while the code and sales data of one product registered for sale immediately before are stored in the registration data buffer. Then, it is determined whether or not the product in this buffer is the same as the product registered this time. If they are the same, the sales data of the product this time is added to the sales data in the buffer, and the receipt is not printed. On the other hand, when the product in the buffer is different from the registered product this time, the data in the buffer is printed on the receipt,
The code and sales data of the current product are stored in the buffer. Further, when the registration closing operation is performed, the data in the buffer is printed on the receipt. Therefore, when the same product is continuously registered for sale, it is collectively printed as one registration data on the receipt.

For the journal, real-time printing in response to the sales registration operation and buffering printing at the same timing as the receipt can be selected.

[Embodiment] An embodiment in which the present invention is applied to an electronic cash register will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an electronic cash register. In the figure, 11 is a CP as the main body of the control unit.
U (Central Processing Unit), which has a built-in arithmetic circuit, memory control circuit, etc., performs various arithmetic processes based on input data, and also stores fixed data such as programs for executing various tasks. It controls the ROM 12 and the RAM 13 that stores variable data such as input data and arithmetic processing data. In addition, the clock circuit 14 that measures the current time, POS
Input a signal from the transmission interface 15 that performs data transmission with the host controller when using it as a POS terminal in the system, and the mode switch 16 to select each business mode such as “registration”, “payment”, and “setting” I / O port 17, a keyboard input circuit 19 for inputting and processing key signals from the keyboard 18, a display control circuit 21 for driving and controlling a display section 20 for displaying the number of items sold and the amount of sale, and a receipt. And the printer drive circuit 23 and drawer 24 of the printer 22 for printing on the journal
I / O port 2 that outputs a drive signal to the drawer opening device 25 and
6, I / input the signal from the code reader 27 for reading the PLU code that has been barcoded and attached to the product
The O port 28 and the like are connected to the CPU 11.

On the keyboard 18, as shown in FIG. 2, a number key 31 for entering the number of items to be sold, the amount of sale, the amount of deposit from customers, etc., and a department code for classifying the items for sale are entered. Department key 32 for, PLU set for the product for sale
Various types such as PLU key 33 used to enter codes, subtotal key 34, deposit / cash total key 35 functioning as registration closing key, multiplication key 36 used to enter points of sold products, cancel key 37 used to immediately cancel A key is provided.

Further, in the RAM 13, as shown in FIG. 3, in addition to the sales registration file 41 for collecting the sales data of the registered sales products for each department code, at least the unit price for each PLU code, the product data of the link department, etc. Remembered PLU
Table 42, totalizer 43 for calculating the total amount of money for one customer, flag memory 44 of registration flag F1 indicating whether registration is in progress, flag memory 45 of journal print flag F2, display buffer 46, print buffer 47 , A code area a1, a unit price area a2, a point area a3, and a price area a4, and a registration data buffer 48 for storing the corresponding data of the product registered for sale immediately before are formed.

Here, the journal print flag F2 is reset to "0" when the printing on the journal is real-time printing in response to the sales registration operation, and the buffering printing is performed at the same timing as the printing on the receipt. In this case, it is set to "1", it functions as a journal print selection means, and "1" or "0" is arbitrarily operated by a predetermined key operation while the "setting" mode is selected by the mode switch 16. Is set.

Then, the CPU 11 is configured to execute the processing shown in the flowchart of FIG. 4 in a state where the “registration” mode is selected by the mode switch 16. That is,
When the product to be sold is registered through the keyboard 18 or the code reader 27 as ST (step) 1, the journal print flag F2 of the flag memory 45 is checked as ST2. Then, when the flag F2 is reset to "0", the real-time printing is selected for the journal, so the code of the product registered for sale in ST3, the sales amount, etc. are printed on the journal. In addition, the sales number and sales price of the products registered for sale as memory processing of ST4 are totaled in the sales registration file for each department code,
The sales amount is added to the totalizer 43. On the other hand, when the journal print flag F2 is set to "1", the buffering print is selected.
And ST4 are not processed.

Next, as ST5, the flag F1 being registered in the flag memory 44 is checked. Then, when the registration flag F1 is reset to “0”, it means that the first product is registered for sale to the customer. Therefore, the code, unit price, sales point, and sales amount of the registered product are stored in the registration data buffer 48. Store, set flag F1 during registration to "1", and return to ST1.

If the registration flag F1 is set to "1" in ST5, it means that the second and subsequent products are registered for sale to the customer.
As ST6, it is determined whether or not the registered product this time is the same as the product stored in the registration data buffer 48 (product determination means). And when it is determined that they are the same product,
The number of sales and the amount of sales of the registered product are added to the number-of-sales area a3 and the amount-of-sales area a4 in the registration data buffer 48 (sales data updating means), and the process returns to ST1.

On the other hand, if it is determined in ST6 that the product in the registration data buffer 48 is different from the product registered this time, the registration data in the buffer 48 is printed on the receipt (receipt print control means). If the journal print flag F2 is set to "1", the corresponding buffer 48
The registered data inside is also printed on the journal, and the same memory processing as ST4 is performed. Then register data buffer
After clearing 48 once, store the code, unit price, number of sales, and sales amount of the newly registered product,
Return to 1.

No product sales registration in ST1, deposit / cash total key in ST7
When the key is operated on the key 35, the registration data in the registration data buffer 48 is printed on the receipt because the customer has performed the registration closing operation (receipt printing control means). Also,
When the journal print flag F2 is set to "1", the registered data in the buffer 48 is also printed in the journal, and the same memory processing as ST4 is performed. afterwards,
As the closing process, the change calculation and the total of the receipt and the journal, the deposit amount, and the change amount are printed, and the long receipt is performed and the receipt is issued. Further, the registration data buffer 48 and the totalizer 43 are cleared, the in-registration flag F1 is reset to "0", and the process returns to ST1 to prepare for the registration of the next customer.

In this embodiment having such a configuration, it is assumed that each customer has now registered each product in the following order.

Register only one item A with a unit price of 100 yen via the keyboard 18. In this case, the registration data buffer 48 stores the number of sales [1] and the sales amount [100] together with the code and unit price of the product A.

Register only one item A above through the keyboard 18. In this case, since the product in the registration data buffer 48 and the product registered this time are the same product, the number of sales in the buffer 48 is updated to [2] and the sales amount is updated to [200].

Register only one item A above through the keyboard 18. In this case, since the product in the registration data buffer 48 and the product registered this time are the same product, the number of sales in the buffer 48 is updated to [3] and the sales amount is updated to [300].

Register only one B product with a unit price of 70 yen via the keyboard 18. In this case, since the product in the registration data buffer 48 is different from the product registered this time, the registration data for the A product in the buffer 48 is printed on the receipt in the multiplication format, and the code of the B product is stored in the registration data buffer 48. , Sales price [1] and sales price [70] along with unit price
Is stored.

Only 5 items of the above B product are registered through the keyboard 18. In this case, since the product in the registration data buffer 48 and the product registered this time are the same product, the number of sales in the buffer 48 is updated to [6] and the sales amount is updated to [420].

Only one C product with a unit price of 500 yen is registered through the code reader 27. In this case, in this case, since the product in the registration data buffer 48 is different from the product registered this time, the registration data for the B product in the buffer 48 is printed on the receipt in the multiplication format, and the registration data buffer 48 displays C The sales code [1] and sales price [500] are stored together with the product code and unit price.

Only one C product is registered through the code reader 27. In this case, since the product in the registration data buffer 48 and the product registered this time are the same product, the number of sales in the buffer 48 is updated to [2] and the sales amount is updated to [1000].

Only the above two C products are registered through the code reader 27. In this case, since the product in the registration data buffer 48 and the product registered this time are the same product, the number of sales in the buffer 48 is updated to [4] and the sales amount is updated to [2000].

After entering the deposit amount of 10,000 yen, enter the deposit / cash total key 35 and perform the tightening operation. In this case, first, the registration data relating to the C product in the registration data buffer 48 is printed on the receipt in a multiplication format, then the total amount [2720], the deposit amount [10000], and the change amount [7280] are printed, and then the receipt. Is issued. An example of issuing a receipt at this time is shown in FIG.

As described above, according to the present embodiment, when the same product is continuously registered, the data of the same product is not repeatedly printed, but the sales data is collected only for the continuously registered data. Can be printed out in multiplication format. Therefore, even if the same product is continuously registered, the print contents on the receipt are simplified and are very easy to see, and the number of print lines is small, and the receipt paper is saved. Since the registration data of the product printed after the closing operation is for one product, there is no fear that the time from the closing operation to the receipt issuance will be long.

On the other hand, when printing on the journal, the journal print flag
According to the setting of F2, it is possible to select whether to carry out in response to the sale registration of the product (real-time printing) as in the conventional case or at the same timing as the receipt of this embodiment (buffering printing). That is, set the journal print flag F2 to "0".
By resetting to and selecting real-time printing, the registration data of the product is printed out on the journal in response to the registration operation of the product. FIG. 6 shows an example of printing journals corresponding to the registration examples 1 to 3 at this time.

Further, by setting the journal print flag F2 to "1" and selecting the buffering print, the same registration data is printed out on the journal at the same timing as the receipt printing timing. FIG. 7 shows an example of printing journals corresponding to the registration examples 1 to 3 at this time.

In this way, real-time printing or buffering printing can be selected for the journal. Therefore, with regard to journal printing, real-time printing is selected at sales floors where registration operations are fast, such as in the grocery sales floor, and sometimes the order of registration is checked by the journal. However, it is possible to select the buffering printing at the sales floor where the registration order is not required to be confirmed, such as selecting the buffering printing.

Although the soft switch based on the journal print flag F2 is described as an example of the journal print selecting means in the above-described embodiment, a hard switch such as a DIP switch may be used for selection. It goes without saying that the present invention can also be applied to a POS system. other than this,
Various modifications can be made without departing from the spirit of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, one registration is performed for each receipt when the same product is continuously registered without increasing the time from the tightening operation to the receipt issuance. It is possible to provide a merchandise sales data processing device that can collectively print out as data, issue a simplified and easy-to-read receipt, and save paper.

Further, according to the second aspect, it is possible to provide the product sales data processing device capable of selecting the buffering printing similar to the receipt or the real time printing similar to the conventional one to the journal.
