Abstract

PURPOSE:To issue a simplified receipt which can be easily observed by storing the code and selling data of a commodity, for which sales registration is executed in advance, and adding the selling data when the commodity, for which the sales registration is next executed, is same as the commodity in a registering data buffer. CONSTITUTION:A registering data buffer 48 is provided to store the code and selling data of the commodity, for which the sales registration is executed just in advance, and it is decided whether the commodity, for which the sales registration is next executed, is same as the commodity in the registering data buffer 48 or not. In case of the same commodity, the selling data are added to the selling data in the registering data buffer and in case of the different commodity, the data in the registering data buffer 48 are moved to an EP- character buffer 47 in correspondence to registration end operation, printed and outputted to the receipt by a printer. Thus, when the same commodity is continuously sold and registered, the commodities are totally printed as one type of registering data to the receipt. Then, the simplified receipt, which can be easily observed, can be issued. Further, a form can be saved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device such as an electronic cash register or a PO3 (point of sale) system used in a store.

[Prior Art] In a conventional product sales data processing device that aggregates sales data of each product registered for sale in a memory, for example, by department code or by PLU (Price Look Up) code, there is a sales registration of the product. It was common practice to print the registration data on receipts and journals for each transaction. In addition, it is equipped with a buffer for storing the code and sales data of the most recently registered product, and in response to a key operation of the last minute cancellation key, only the last registered product can be canceled based on the data in this buffer. A product sales data processing device has been put into practical use, but even with this device, the timing of printing on receipts and journals is done in response to product sales registration, and if there is a last-minute cancellation, cancellation printing is performed. I am doing it.

[Problems to be Solved by the Invention] However, in a device that responds to a sales registration operation and prints out the registration data of the product on a receipt and a journal, although it has the advantage that the time from the closing operation to issuing the receipt is short, When the same product is registered continuously, the registration data of the same product is repeatedly printed on the receipt and journal, which makes it difficult to see the printed content and wastes paper. Journals sometimes check the order of registration operations, so it may be necessary to print out the order of registration, but receipts confirm the products purchased by the customer, so they need to be simplified and easy to read.

Therefore, the present invention does not increase the time from the closing operation to issuing the receipt, and when the same product is registered continuously, the receipts can be printed out as one registered data, which is simplified and easy to read. The purpose of the present invention is to provide a product sales data processing device that can issue receipts and save paper.

[Means for Solving the Problems] The present invention aggregates sales data of products registered for sale by code in a memory, prints them on receipts and journals using a printer, and issues receipts in accordance with registration scanning operations. In the product sales data processing device that performs sales, it is determined whether 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 registered for sale next is the same as the product in the registration data buffer. a product determining means for determining that the products are the same; a sales data updating means for adding sales data obtained when the determining means determines that the products are the same to sales data in a registered data buffer; Receipt printing control means causes the printer to print out the data in the registration data buffer on a receipt upon determination or in response to the registration closing operation.

In addition, there is a real-time printing means that prints out the registered product data to the journal in response to product sales registration, and a buffering means that prints out the data in the registered 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 means and a journal printing selection means for selecting either real-time printing means or buffering printing means.

[Operation] With a product sales data processing device that takes such measures, the next product is registered for sale with the code and sales data of the product that was recently registered for sale stored in the registration data buffer. Then, it is determined whether the product in this pamphlet and the currently registered product are the same. If they are the same, the sales data for the current product is added to the sales data in the buffer, and no printing is performed on the receipt. On the other hand, if the product in the buffer is different from the currently registered product, the data in the buffer is printed on the receipt, and the code and sales data of the current product are stored in the buffer. Furthermore, even when a registration closing operation is performed, the data in the buffer is printed on the receipt. Therefore, if the same product is registered for sale one after another, all of the data will be printed on the receipt as one piece of registration data.

For the journal, it is possible to select between real-time printing in response to sales registration operations and buffering printing at the same timing as the receipt.

[Example] Hereinafter, an example in which the present invention is applied to an electronic cash register will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an electronic cash register. In the same figure, 11 is C as the main body of the control section.
A PU (Central Processing Unit) with built-in four arithmetic circuits, memory control circuits, etc., which performs various arithmetic processing based on input data and stores fixed data such as programs for executing various tasks. A ROM 12 for storing input data, arithmetic processing data, and other variable data.
AM13 is controlled. In addition, there is a clock circuit 14 that measures the current time, a transmission interface 15 that performs data transmission with a host controller when used as a POS terminal in a POS system, "registration" and "payment".
I10 boat 17 that inputs signals from mode switch 16 for selecting each business mode such as "setting", keyboard input circuit 19 that inputs and processes key signals from keyboard 18, number of sales of registered products, I10 outputs a drive signal to a display control circuit 21 that drives and controls a display unit 20 for displaying sales amounts, etc., a printer drive circuit 23 of a printer 22 that prints on receipts and journals, and a drawer opening device 25 of a drawer 24; port 2
6. Input the signal from the code reader 27 for reading the PLU code attached to the product in the form of a bar code; the S I/O boat 28 etc.
11 2 are connected.

As shown in FIG. 2, the keyboard 18 includes number keys 31 for inputting the number of sales items, sales amount, deposit amount from customers, etc., and department codes for classifying sales items. department key 32, PLU key 33 used to input the PLU code set for the sales item, subtotal key 34, and deposit/cash total key 35 that functions as a registration closing key.
, a multiplication key 36 used for inputting the number of items for sale, and a cancellation key 37 used for last-minute cancellation.

In addition, as shown in FIG. 3, the RAM 13 stores, in addition to a sales registration file 41 that aggregates sales data of products registered for sale, for example, by department code, product data such as at least unit price and link department for each PLU code. A PLO table 42 that stores , a totalizer 43 for calculating the total amount of - customers, and a registration flag F that indicates whether registration is currently underway.
1 flag memory 44, journal print flag F2 flag memory 45, display buffer 46, print buffer 47
, code area al, unit price area a2゜ point area a
3 and an amount area a4, a registration data buffer 48 stores the corresponding data of the product registered for sale immediately before;
etc. are formed.

Here, the journal printing flag F2 is reset to "0" when printing on the journal is performed in real time in response to a sales registration operation, and buffering printing is performed at the same timing as printing on the receipt. This function is set to "1" when the print mode is selected, and functions as a journal print selection means.
With the mode selected, "1" or "0" is set to 1 mode by operating a predetermined key.

Thus, with the "registration" mode selected by the mode switch 16, the CPU II is configured to execute the process shown in the flowchart of FIG. That is, when a product for sale is registered via the keyboard 18 or code reader 27 in ST (step) 1, the journal print flag F2 in the flag memory 45 is checked in ST2. If the flag F2 is reset to "0", real-time printing is selected for the journal, so the code, sales amount, etc. of the product registered for sale are printed on the journal in ST3. Further, as a memory process in ST4, the number of sales items and sales amount of the products registered for sale are totaled by department code in the sales registration file, and the sales amount is added to the totalizer 43. On the other hand, if the journal print flag F2 is set to "1", buffering printing is selected, and therefore the above-described processes of ST3 and ST4 are not performed.

Next, as ST5, the registration flag F in the flag memory 44 is
Check 1. If the registration flag F1 is reset to "0", this is the first product sales registration for the customer, so the code, unit price, number of sales items, etc. of the registered product,
The sales amount is stored in the registration data buffer 48, the registration flag F1 is set to "1", and the process returns to ST1.

If the registration flag F1 is set to "1°" in ST5, the second or subsequent product is registered for sale to the customer, so the currently registered product is stored in the registration data buffer 48 in ST6. Determine whether it is the same as the product (product determination means).

If it is determined that the products are the same, the sales number and sales amount of the current registered product are added to the sales number area a3 and sales amount area a4 in the registered data buffer 48 (sales data update 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 and the currently registered product are different products,
Prints the registration data in the buffer 48 on a receipt (receipt printing control means) Also, if the journal print flag F2 is set to "1", prints the registration data in the buffer 48 on the journal, Katsu S
Memory processing similar to T4 is performed. Thereafter, the registration data buffer 48 is cleared once, and the code, unit price, number of sales items, and sales amount of the newly registered product are respectively stored, and the process returns to STI.

If there is no sales registration for the product at STI and the 5/Cash key 35 is operated in ST7, the registration data in the registration data buffer 48 is used as a receipt because the customer has been asked to close the registration. Print (receipt printing control means)
. Furthermore, if 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 in ST4 is performed. After that, as a closing process, change is calculated, and the total and deposit amount for cash register 4 and journal are calculated.

It prints the amount of change, performs a long receipt, and issues a receipt. It also clears the registration data buffer 48 and totalizer 43, resets the registration flag F1 to "0", returns to STI, and prepares for registration for the next customer.

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

■ Only one product A with a unit price of 100 yen is registered via the keyboard 18. In this case, the registration data buffer 48 stores the code and unit price of product A, as well as the number of sold items [1] and the sales amount [1001].

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

■ Register only one product A above using the keyboard 18. In this case, since the product in the registration data buffer 48 and the currently registered product are the same product, the number of sales items in the buffer 48 is updated to [3] and the sales amount is updated to [3001].

■ Only one B product with a unit price of 70 yen is registered via the keyboard 18. In this case, since the product in the registration data buffer 48 and the currently registered product are different products, the registration data regarding product A in the buffer 48 is printed on the receipt in multiplication format, and the registration data in the registration data buffer 48 is printed on the receipt.
The number of sold items [1] and the sales amount [70] are stored together with the product code and single dli.

■ Register only five of the above B products using the keyboard 18. In this case, since the product in the registration data buffer 48 and the currently registered product are the same product, the number of sales items in the buffer 48 is updated to [6] and the sales amount is updated to [420F].

■ Code reader 27 for only one C product with a unit price of 500 yen
Register via. In this case, since the product in the registration data buffer 48 and the currently registered product are different products, the registration data related to product B in the buffer 48 is printed on the receipt in multiplication format, and the product is stored in the registration data buffer 48. stores the code and unit price of product C, as well as the number of sold items [1] and the sales amount [500].

■ Register only one product C above through the code reader 27. In this case, since the product in the registered data buffer 48 and the currently registered product are the same product, the buffer 48
The number of sales items is updated to [2] and the sales amount is updated to [1000].

■ Register only two of the above C products via the code reader 27. In this case, since the product in the registered data buffer 48 and the currently registered product are the same product, the buffer 48
The number of sales items is updated to [4] and the sales amount is updated to [2000].

■ After entering the deposit amount of 10,000 yen, flI! 1/Current key 3
Manually perform the tightening operation in step 5. In this case, the registration data regarding product C in the registration data buffer 48 is first printed on the receipt in multiplication format, and then the total amount [
2720], Tjii amount [10,000 ko, change amount [7
280] is printed, the receipt is issued. An example of one receipt issued at this time is shown in FIG.

In this way, according to this embodiment, when the same product is registered consecutively, the data for the same product is not repeatedly printed, but the sales data for the consecutively registered items are printed together. Can be printed out in multiplication format. Therefore, even if the same product is registered continuously, the printed content on the receipt is simplified and becomes very easy to read, and the number of printed lines is small, saving receipt paper. In addition, the registration data of one product is enough to be printed after the tightening operation, so
There is no risk that the time from the closing operation to the issuance of a receipt will be long.

On the other hand, for printing on the journal, the journal print flag F
By setting 2, it is possible to select whether to perform the printing in response to product sales registration as in the past (real-time printing), or at the same timing as the receipt in this embodiment (buffering printing). In other words, the journal print flag F2 is set to O.
By resetting to `` and selecting real-time printing, the registration data of the product will be printed out on the journal in response to the product registration operation.The following is an example of the journal printout for the above registration examples ■ to ■. This is shown in Figure 6.

Furthermore, by setting the journal print flag F2 to "1" and selecting buffering printing, the same registered data is printed out on the journal at the same timing as the print timing on the receipt. Examples of printed journals for the registration examples ① to ① at this time are shown in FIG.

In this way, real-time printing and buffering printing can be selected for the journal.

Therefore, when it comes to journal printing, real-time printing is selected in stores where the registration operation is fast, such as a grocery store, and where the registration order is sometimes checked using a journal, and real-time printing is selected, such as in a clothing department. It is possible to use this method depending on the purpose, such as selecting full-fill printing in sales areas where the speed is slow and checking the registration order is not necessary.

In the above embodiment, a soft switch based on the journal print flag F2 was exemplified as the journal print selection means, but selection may be made using a hard switch such as a dip switch. It goes without saying that the present invention can also be applied to POS systems. In addition, various modifications can be made without departing from the gist of the present invention.

[Effects of the Invention] As detailed above, according to the present invention, the time from the closing operation to the issuance of the receipt does not become long, and when the same product is registered continuously, the receipt is recorded as λ=j. To provide a product sales data processing device that can print out all registered data as one piece of registration data, issue a simplified and attractive receipt, and save paper.

Further, according to claim 2, it is possible to provide a quadruple sales data processing device that can select between buffering printing on the journal and receipts, and real-time printing as in the past.
