SUMMARY OF THE INVENTION In ordinary households,
In some cases, household accounts are classified according to product categories such as food, miscellaneous goods, and clothing. In this case, it is necessary to record a consumption tax amount for each product category. However, conventional ECR
In the POS terminal, the consumption tax is calculated as a tax amount on the subtotal amount of all the products purchased by the customer, and the consumption tax amount for each product category is not calculated. Therefore, the consumption tax amount for each product category is not printed on the receipt.
For this reason, in a household that has a household account book classified by product category, products arranged in the order of operator input recorded on the receipt are sorted by product category, and the total amount is calculated for each product category. They are forced to work around the calculation of consumption tax based on the amount of money.

Japanese Patent Application Laid-Open No. 5-258 based on the application of the present applicant
No. 178 discloses an ECR which prints and issues a receipt in which merchandise names and prices are merged for each merchandise category. In such a receipt issued by the ECR, the product name and price of the product are recorded in a form organized by product category, so that it is easy to classify by product category and attach a household account book. However, JP-A-5-258178 does not mention calculating a consumption tax amount for each product category and printing this on a receipt.

[0005]

According to the first aspect of the present invention,
In a product sales data processing device, a total sales amount including a price and a consumption tax of the product is obtained on condition that the product code is input, and a receipt on which sales details are recorded is printed and issued at a predetermined timing. Consumption tax is calculated separately, and sales details with consumption tax are printed on receipts for each product category. Therefore, since sales receipts with consumption tax are printed on the receipts for each product category, households who keep their household accounts by classifying them by product category do not need to sort products. There is no need to calculate consumption tax based on the total amount for each category.

According to a second aspect of the present invention, there is provided a merchandise sales data processing apparatus, comprising: input means for specifying a merchandise code; a merchandise master file for storing at least a unit price and a merchandise classification of the merchandise for each merchandise code; Product information retrieval means for retrieving product information corresponding to the product code from the product master file, and classification at a predetermined timing for obtaining the total sales amount including consumption tax for each product classification for the product called by the product information retrieval means. The system includes a total sales calculating means and a receipt creating means for driving and controlling a receipt printer to print a sales statement with a consumption tax for each product category on the receipt. Therefore, when a product code is input by the input unit, the product information search unit searches the product master file, so that the product information corresponding to the corresponding product code is called. Then, at a predetermined timing, a total sales amount including a consumption tax is obtained for each product classification for the product for which the sales total calculation means for each classification is called, and the consumption control for each product class is performed by the subsequent receipt printer driving control by the receipt creation device. The sales details with tax are printed on the receipt. Therefore, in a household that has a household account book classified according to product category, it is not necessary to rearrange the products, and it is also unnecessary to calculate a consumption tax based on the total price for each product category.

FIG. 6 is a flowchart schematically showing the flow of the product registration process. First, barcode scanner 1
1 waits for input of product information by reading a bar code or the like (step S1). The product information in this case is a product master file MF that specifies each product.
This is the scan code inside, this scan code is JA
Although a code conforming to the N code system is generally used, a code conforming to another code system such as an in-store code may be used. If it is determined in step S1 that the product information has been input, the microcomputer 12 searches the product master file MF for a corresponding product based on the scan code (product information search means), and drives the display 9 and the customer display unit 10. Control is performed to display the product name and price of the product (step S2). In the following step S3, among the product information retrieved from the product master file MF retrieved by the product information retrieval means, the product name, unit price, and classification are stored in the corresponding areas of the registered content storage area shown in FIG.
Then, in step S4, the amount is added to the total amount storage area of the total amount by product category / consumption tax storage area shown in FIG. 5, and in step S5, the amount is consumed by the consumption tax storage area of the total amount by product category / consumption tax storage area. Taxes will be added. For example, when a scan code indicating a paper cup is input in step S1, in step S3, the product name of the registered content storage area is “paper cup” and the unit price is “260”.
(Yen) "and" 2 "are temporarily stored in the classification. In step S4," 260 (yen) "is added and temporarily stored in the total amount storage area of the total amount per item classification / consumption tax storage area. In S5, "8 (yen)" is added to the consumption tax storage area of the total price per item classification / consumption tax storage area and temporarily stored. Therefore, by the processes of steps S4 and S5, the function of the category-based total sales calculation means for obtaining the total sales amount including the consumption tax for each product classification for the searched products is executed.

The processing of steps S1 to S5 is repeated until the subtotal key in the keyboard 4 is pressed (step S6). When the subtotal key determined in step S6 is pressed, the subtotal amount is displayed on the display 9 and on the customer side. It is displayed on the unit 10 (step S7). At this time, the calculation processing of the subtotal amount is performed while the processing of steps S1 to S5 is being executed. After displaying the subtotal amount, if there is a product input again without the closing process, steps S1 to S7
Are repeated (Step S8), and Step S8
The commodity registration processing of step S9 and subsequent steps is performed by the closing processing determined in step 8, and the processing ends. Here, the “close process” is, for example, declared by pressing a deposit / current key on the keyboard 4 in the case of cash payment, and declared by pressing a credit key in the keyboard 4 in the case of credit payment. . In the product registration process after the closing process, H
Registration processing of sales data finally stored in the sales total memory in the DD 17 (step S9), withdrawal 3 of the drawer 2
Is released (step S10), the line printer 22 records the transaction details in a journal (step S11), and the line printer 22 prints and issues a receipt on which the transaction details are recorded (steps S12 to S18).

Here, details of the receipt print issuance processing (steps S12 to S18) will be described. First, in the receipt print issuance processing, predetermined print data is transferred to an edit buffer set in a partial area of the RAM 16 and the contents of the edit buffer are developed in an image memory set in a partial area of the RAM 16. Then, a printing operation by the line printer 22 is performed based on the contents of the image memory. The order of the print data sent to the edit buffer and its processing are as follows. In step S12, RAM1
The product name and unit price for which the product classification is “1 (food)” in the registered content storage area (see FIG. 4) in 6 are sent to the editing buffer, and are developed in the image memory in the order of “product name, unit price, (food)”. Is printed. In the following step S13, RA
The storage contents of the total amount storage area and the consumption tax storage area of the category 1 (food) in the total price / consumption tax storage area (see FIG. 5) for each product category in M16 are sent to the editing buffer and expanded in the image memory. Printed. Next, in step S14, the product name and unit price whose product classification is "2 (Miscellaneous goods)" in the registered content storage area (see FIG. 4) in the RAM 16 are sent to the editing buffer, and the "product name, unit price,
(Miscellaneous) "in the image memory and printed.
In the following step S15, the storage contents of the total amount storage area and the consumption tax storage area of the category 2 (miscellaneous goods) in the total amount by commodity classification / consumption tax storage area in the RAM 16 are sent to the editing buffer, and are developed in the image memory. Printed. Then, in step S16, the product name and unit price for which the product classification in the registered content storage area (see FIG. 4) in the RAM 16 is "3 (clothing)" are sent to the editing buffer, and the "product name, unit price, (clothing)" The data is developed and printed in the image memory in order. In the following step S17, RAM1
The storage contents of the total amount storage area and the consumption tax storage area of the category 3 (clothing) in the total price per item category / consumption tax storage area in No. 6 are sent to the editing buffer, developed and printed in the image memory. Then, in step S18,
Information relating to "subtotal, total tax amount, custody, change" is sent to the editing buffer, developed and printed in the image memory. Here, the function of the receipt creating means for driving and controlling the line printer 22 functioning as a receipt printer and printing the sales details with the consumption tax for each product category on the receipt is executed.

FIG. 7 is a plan view showing an example of the issued receipt. By the processing of steps S12 to S18 in FIG. 6, the purchased goods are arranged on the receipt by product category, and the sales details with the consumption tax are printed on the product category.

Although this embodiment has been described as an example of application to ECR, it may be applied to a POS system or a POS terminal.

In this embodiment, the HDD 17 is used as a medium on which the control program is recorded. However, as the medium, a floppy disk or a ROM 15 may be used.
And the like may be used.

[0025]

According to the present invention, since the consumption tax is calculated for each product category and the sales statement with the consumption tax is printed on the receipt for each product category, the sales tax for each product category is printed on the receipt. The details can be printed, and therefore, in households that keep a household account book by categorizing by product category, there is no need to sort products, and there is no need to calculate consumption tax based on the total price for each product category. Thus, it is possible to support household account book work.
