Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an electronic cash register or a POS terminal having a transaction data buffer for accumulating sales data of a sales commodity input through an input device for one customer. Related to the product sales data processing device.

[Prior Art] In a conventional product sales data processing device such as an electronic cash register or a POS terminal, a transaction data buffer is formed in an internal RAM, and a product sold to one customer is sold through a keyboard, a bar code scanner or the like. When the sales data is entered, the sales data is registered in the memory for sales totalization and stored in the transaction data buffer, and the collective cancellation key is used to cancel the sales registration for the customer. There is a so-called batch cancellation function of executing the return registration to the sales totaling memory with all the sales data accumulated in the transaction data buffer. In such a device, when the cancellation sales data of the canceled product is input before the sales registration closing operation, when the cancellation sales data is the same as the sales data at the time of sales registration stored in the transaction data buffer. It also had a so-called selection cancellation function, which only executes return registration.

In addition, in a product sales data processing device such as an ordinary electronic cash register or a POS terminal, the printer is operated each time the sales data of the sales product or the cancellation data of the cancellation product is input, and the product name, price, points, etc. are displayed. It was printed out on the receipt.

[Problems to be Solved by the Invention] However, in the product sales data processing device having the above-mentioned batch cancellation function, the sales at the time of sales registration in which the cancellation sales data is stored in the transaction data buffer when the selective cancellation is performed. Since it was possible to cancel only if it was the same as the data, if you want to cancel only 2 items for sale registered with 3 points, you have to perform the cancel operation of 3 points first and then register the sale again with 1 point. However, the operation is complicated and wastes time. Moreover, when the same product is registered for sale several times, there is a problem that the user cannot immediately perform the selection cancel operation if he forgets the contents of the sales registration operation when canceling the selection of the product.

In addition, every time sales data of a sale product or cancellation data of a canceled product was input, it was printed out on the receipt.
If you cancel the selection or register the sales of the same product multiple times, the sales data of the canceled product is printed out or the sales data of the same product is printed out many times. The number increased and sometimes the receipt became unclear.

Therefore, according to the present invention, even if the same product is registered for sale in a plurality of times, it can be collectively stored in the transaction data buffer, and the selection cancellation for the product in this buffer is possible if the sales data number of the product or less. An object of the present invention is to provide a merchandise sales data processing device capable of simplifying the selection cancellation operation and improving workability of registration work.

Further, the present invention intends to provide a product sales data processing device capable of printing receipts collectively after a sales registration closing operation based on sales data in the transaction data buffer, simplifying receipts, and issuing clear receipts. .

[Means for Solving the Problem] The invention according to claim 1 of the present application registers the sales data of the sales product input through the input device in the sales totaling memory, and at the same time stores the code and the sales point data of the sales product. In the product sales data processing device that stores in the transaction data buffer and executes the return registration to the sales totaling memory with all the data stored in the transaction data buffer when the batch cancel key is operated before the sales registration closing operation, When the code of the sale item and the sales point number data are input through the input device, the sale time buffer search means for searching whether the code of the same item is stored in the transaction data buffer and the sale time buffer search means When a code is detected, the sales point data input to the sales point data corresponding to this code is added and processed, and the code of the same product If it is not detected, the buffer accumulation control means that stores the code and sales point data of the sale item input in the empty area of the transaction data buffer, the designated cancellation input means that inputs the code and the cancellation point number data of the cancellation item, and the sales registration Before the closing operation, when the code of the canceled product and the cancellation point data are input by the specified cancellation input means, the transaction data buffer is searched to find out whether the code of the same product is stored. When the search means detects the code of the same product, when the sales point data corresponding to this code is compared with the input cancellation point data, and the cancellation point data is less than the sales point data by this point comparison means. Cancellation entered from sales point data corresponding to the code of the same product in the transaction data buffer It is obtained by a specified cancellation processing means for executing the registration back against sales totalization memory in input data by the specified cancel input means with reducing the number of data.

The invention according to claim 2 of the present application is, in addition to the configuration of the invention according to claim 1, a batch print designating means for designating batch printing of sales data, and a batch printing designation means for designating batch printing of the sales data. It is provided with a collective print control means for prohibiting the print output to the receipt for each input and printing out all the sales data in the transaction data buffer on the receipt after the sales registration closing operation.

[Operation] With the product sales data processing apparatus of the present invention, every time sales data is input via the input device, it is determined whether or not the sales data of the same product is stored in the transaction data buffer, and the same product is sold. Is stored, the input sales data is added to the sales data of the same product, and if the same product is not stored, the input sales data is stored in the empty area of the transaction data buffer. When the cancellation sales data of the canceled product is input before the sales registration closing operation, the cancellation sales data is subtracted from the sales data of the corresponding product in the transaction data buffer, and the cancellation sales data is stored in the sales aggregation memory. Back registration is executed.

Further, if batch printing is designated, the printing output to the receipt, which is performed every time the sales data is input, is prohibited, and all the sales data in the transaction data buffer is printed out to the receipt after the sales registration closing operation.

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

A control key 29 for selecting each operation mode such as "setting" and instructing the execution thereof to the central processing unit, and a dip switch 30 for switching ON / OFF whether to perform batch printing or not are provided.

FIG. 3 is a block diagram showing the internal structure of the electronic cash register. In the figure, reference numeral 31 denotes a CPU (central processing unit) as a main body of a control unit, which incorporates an arithmetic circuit, a memory control circuit, etc., and executes each of the above-mentioned tasks via a bus line 32 such as an address bus or a data bus The ROM 33, which stores fixed data such as a program for storing data, and the RAM 34, which stores variable data such as various input data and arithmetic processing data, are operated. Further, the I / O port 35 for inputting signals from the bar code scanner 17, the control key 29 and the DIP switch 30, the printer drive circuit 37 of the printer 36 for printing a receipt, and the drawer opening device 38 of the drawer 16.

It is connected to the CPU 31 via the bus line 32.

As shown in FIG. 4, in the RAM 34, a setting area for storing the product name and unit price of the product corresponding to, for example, an 8-digit unit code set for each product, the number of sales and the amount of sales of the product A single item file 51 consisting of a totaling area for accumulating totals, a transaction data buffer 52 for accumulating a single item code, a unit price, the number of items sold and the amount of sale as all the transaction data for one customer, a register 53, the total amount for one customer A sum memory 54 for calculating, a point memory 55 for storing the number of sales points keyed in, a flag memory 56 for storing a registration flag F1 indicating that the sales are being registered, and a multiplication flag F2 indicating that the registration is multiplication. And a flag memory 57 for storing

It should be noted that a bar code of a single product code is attached to each product during printing.

Then, the CPU 31 is program-controlled so as to execute the main routine shown in FIG. 5 after the power is turned on and a predetermined initial process is performed. That is, there is no key data input at P1, and the barcode scanner at P2.
When the bar code is read by 17, the control key 29 confirms that the "registration" mode is selected, and then the scanning process shown in FIG. 6 is executed.

When the flow chart in FIG. 6 is started, the single item code is read from the barcode signal fetched by the barcode reader 17 as P11, the single item file 51 is searched with this single item code, and the corresponding item name and unit price are read out and displayed. Bowl 1
Display on 4,15. Next, as P12, the flag memory 57
The state of the multiplication flag F2 is checked, and if it remains cleared to “0”, the sales point is set to “1” and the read unit price is set to the sales amount. On the other hand, if the multiplication flag F2 is set to "1", the number data stored in the point memory 55 is used as the sales point, and the sales point is multiplied by the read unit price to calculate the sales amount. To do. Then, this sales data, that is, the number of sales and the amount of sales are added to the number of sales and the amount of sales corresponding to the single product code read from the single product file 51. Also, the sales amount is added to the totalizer memory 54.

Note that the process up to this point is a normal single item registration process and is a known process.

Next, the switch signal is fetched from the dip switch 30 as P13. Then, when the switch 30 is OFF, that is, when batch printing is not designated, the read product name, unit price, number of sales, and sales amount are printed out on a receipt. On the other hand, when the switch 30 is ON, that is, when batch printing is designated, the above print output is prohibited.

Next, the transaction data buffer 52 is searched with the single item code read as P14. When the same code as the single item code read in P15 is stored in the transaction data buffer 52, it is determined in P16 whether the unit price corresponding to the same code matches the unit price read by the sales registration process. To judge. Then, when the unit prices also match, the sales points and sales amount obtained by the sales registration process are added to the sales data of the same code.

On the other hand, if the same code is not stored in P15,
Alternatively, if the unit prices do not match on P16, the unit code, unit price, and unit price read in the empty area of the transaction data buffer 52,
Stores the number of items sold and the amount sold. Then, the transaction data buffer 52 is rearranged in the order of single-item codes. Thereafter, as P17, the flag F1 being registered in the flag memory 56 is set to "1", and the process returns to the main routine of FIG.

In the main routine of FIG. 5, when key data is input at P1, the type of key data is discriminated after confirming that the "registration" mode is selected by the control key 29. Then, the key data is the multiplication key 28 as P3.
If the input is, the multiplication key processing shown in FIG. 7 is executed. That is, that the register data 53 is stored in the register register 53, this register data is stored in the score memory 55, and the register register 53 is cleared. Then, the multiplication flag F2 is set to "1" and the process returns to the main routine.

In the main routine, if the key data is input by the collective cancel key 24 at P4, the collective cancel key process shown in FIG. 8 is executed. That is, when the registration flag F1 is set to "1", normal return registration is performed for the single item file 51 according to all transaction data in the transaction data buffer 52. Next, the state of the DIP switch 30 is checked, and if the switch is OFF, the sales data of the collectively canceled products is printed on the receipt, so this unnecessary receipt is issued. When the switch is ON, since no printout is printed on the receipt, the unnecessary receipt issuance processing is not performed. Then, the transaction data buffer 52 and the totalizer memory 54 are cleared, and the registration flag F1 is set to "0".
To cancel and return to the main routine.

In the main routine, if the key data is the input of the designated cancellation key 25 at P5, the designated cancellation key process shown in FIG. 9 is executed. That is, when the registering flag F1 is set to "1", the numeric keypad on the keyboard 12
21, Wait for the code, unit price and points of the selected canceled product to be entered via the amount key 26 and the code key 27. When these data are input, the transaction data buffer 52 is searched with the input code. Here, if the same code as the input code as P21 is not stored in the transaction data buffer 52, an error is generated. If the same code exists in the transaction data buffer 52, it is determined whether or not the input unit price as P22 and the unit price corresponding to the same code in the transaction data buffer 52 match. Perform a code search.

When the input unit price matches the unit price of the same code in P22, the input score is compared with the sales score corresponding to the same code in the transaction data buffer 52 in P23. If the number of input points is equal to or less than the number of sales points, the selection can be canceled and the following selection cancellation processing is executed. That is, the number of points and the amount of money (unit price × point) of the input data are subtracted from the number of points sold and the amount of sales of the same data as the input code and unit price in the transaction data buffer 52. Also, the amount of input data is subtracted from the totalizer memory 54. further,
The normal return registration process is executed for the single item file 51 with the code, the number of points, and the amount of money of the input data.

If the number of input points exceeds the number of sales points on P23, it will be an error because the selection cannot be canceled.

In the main routine, key data is deposited / stored as P6
If the current total key 23 is used, the deposit / current total key process shown in FIG. 10 is executed. That is, if the registration flag F1 is set to "1", the state of the DIP switch 30 is checked. When the switch is ON, the sales data is collectively printed on the receipt according to all the data in the transaction data buffer 52. When the switch is OFF, the above batch printing is not performed.

After that, the total amount of money in the totalizer memory 54 is displayed and printed, and the receipt is issued from the receipt issuing port 13.
Further, the transaction data buffer 52 and the totalizer memory 54 are cleared, the registering flag F1 is cleared to "0", and the process returns to the main routine.

In the electronic cash register having such a configuration, the operation will be described first with reference to a specific registration example when the tip switch 30 is OFF, that is, when batch printing is not designated.

As the first sale registration, the product A is multiply-registered by three. That is, after inputting "3" with the numeral key 21 and inputting the multiplication key 28, the barcode of the commodity A is read by the barcode scanner 17. Then, the normal sales registration processing is performed, and the product name, unit price, sales point, and sales amount of the A product are printed out on the receipt, and the product data unit 52 stores the unit code “00000001” and unit price “500” of the A product. The number of sales “3” and the amount of sales “1500” are stored.

Register one C product as the next sales registration. That is, the bar code of the C product is read by the bar code scanner 17.
Then, the normal sales registration processing is performed, and the product name, unit price, sales point, and sales amount of the C product are printed out on the receipt, and since there is no identical product in the transaction data buffer 52, a new product of the C product is sold. The code “00000003”, the unit price “800”, the number of sales points “1”, and the sales amount “800” are stored.

As the next sales registration, the product A is multiplied by five and registered. Then, the normal sales registration processing is performed, and the product name, unit price, sales point, and sales amount of the A product are printed out on the receipt, and the data of the A product is stored in the transaction data buffer 52. The number of sales of the A product newly entered in the data of the A product is "5" and the sales amount is "25".
00 ”is added.

As the next sales registration, the product B is multiply-registered by two. Then, the normal sales registration processing is performed, and the product name, unit price, sales point, and sales amount of the B product are printed out on the receipt, and since there is no identical product in the transaction data buffer 52, a new product of the B product is sold separately. The code “00000002”, the unit price “300”, the number of sales points “2”, and the sales amount “600” are stored.

Register one C product as the next sales registration. Then, the normal sales registration process is performed, and the product name, unit price, sales point, and sales amount of the C product are printed out on the receipt, and the data of the C product is stored in the transaction data buffer 52. The sales number “1” and the sales amount “800” of the C product newly input to the data of the C product are added.

The contents of the transaction data buffer 52 at this point are as shown in FIG. In this state, when performing batch cancellation, the batch cancellation key 24 may be operated.

On the other hand, as the selection cancellation, two A products are canceled. That is, after operating the designated cancel key 25, enter the code "00000001" with the numeric keypad 21 and enter the code key 27, and enter the unit price "500" with the numeric keypad 21 and enter the amount key. Enter 26, enter the number of cancellation points "2" with the numeric key, and enter the multiplication key 28. Then the undo data buffer
The number of sales points is subtracted from the item A data in 52 by “2” to be “6” and the sales amount is subtracted from “1000” to be “3000”. Further, the return registration for the two products A in the single-item file 51 is performed, and the cancel printing is performed.

Next, as the selection cancellation, the operation for canceling the four products A is performed. Then, similarly, the sales point is further subtracted by "4" from the A product data in the cancellation data buffer 52 to be "2", and the sales amount is reduced by "2000" to be "1000". Further, the return registration for the four A commodities in the single-item file 51 is performed, and the cancel printing is performed.

Next, as the selection cancellation, two C commodities are canceled. Then, the sales points are subtracted from the C merchandise data in the cancellation data buffer 52 by "2" to be "0" and the sales amount is subtracted from "1600" to be "0". In addition, the return registration for two C commodities in the single commodity file 51 is performed,
In addition, cancellation printing is performed.

After that, the deposit / cash total key 23 is input to close the sales registration for the customer. Then, the totalizer memory
The total amount "1600" in 54 is printed out on the receipt,
The receipt shown in Fig. 11 is issued.

On the other hand, when the DIP switch 30 is ON, that is, when the batch printing is designated, the printing output to the receipt is prohibited until the registration closing operation is performed. Then, when the registration closing operation, that is, the deposit / cash total key 23 is input, printout is performed on the receipt according to the data in the transaction data buffer 52, the total amount is printed, and the receipt is issued. At this time, the data whose sales data is "0" is not printed out. That is, the receipt issued by batch printing in the registration example is as shown in FIG.

As described above, in this embodiment, when the sales data is stored in the transaction data buffer 52, if the sales data of the same product is already stored, the input sales data is added to the data. . When the selection cancellation of the product in the cancellation data buffer 52 is performed, the selection cancellation is possible if the sales data number of the product is not more than the sales data number. Therefore, for example, in the case of canceling two products for which three multiplications have been registered, it has conventionally been necessary to cancel three products and then re-register one product, but in this embodiment, one selection is made. Two can be canceled by the cancel operation. Also, for example, if the same product is registered with 3 multiplications and 4
In the case of registering a total of 7 pieces by multiplication registration of pieces and canceling all of this product, conventionally, it was necessary to cancel 3 pieces first and then 4 pieces again. However, according to the present invention, A total of 7 cancellations can be made with a single selection cancellation operation.

Thus, according to the present embodiment, the key operation for canceling the selection can be simplified, the load on the cashier can be reduced, and
The time required for cancellation can be shortened and workability can be improved.

Further, in the above-described embodiment, by switching the dip switch 30, it is selected whether the printout to the receipt is performed at the same time as the sales registration or collectively after the closing operation of the sales registration. When the batch printing is selected, the transaction data buffer 52 performs the addition processing of the sales data as described above. Therefore, as is clear from the comparison between the receipt issuing examples of FIG. 11 and FIG. The product data will no longer be printed out and the canceled product data will not be printed out. As a result, the number of printing lines is reduced, the receipt is simplified, and the receipt is easy to see, and the receipt can be saved. However, this batch printing requires a processing time after the tightening operation, so when the store is crowded, the DIP switch 30 is turned off to stop the batch printing to speed up the processing.

In the above embodiment, the electronic cash register having the single file 51 in the internal RAM 34 is exemplified.
Needless to say, it can be applied to a POS terminal equipped with a file controller that is externally connected online. Further, in the above-described embodiment, the case where the batch printing is switched or not is illustrated by the DIP switch 30. However, for example, program control may be performed so as to automatically switch depending on the time zone between the time of congestion and the time of conversion. Good. 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, the following effects are achieved.

That is, according to claim 1, even if the same merchandise is registered for sale in multiple times, it can be collectively stored in the transaction data buffer, and the selection cancellation for the merchandise in this buffer can be performed with the number of sales data of the merchandise or less. If possible, it is possible to provide a merchandise sales data processing device capable of simplifying the selection cancellation operation and improving the workability of registration work.

Further, according to claim 2, in addition to the above effect, it is possible to perform batch printing of the receipt after the sales registration closing operation based on the sales data in the transaction data buffer, the receipt can be simplified, and a clear receipt can be issued. A product sales data processing device can be provided.
