DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an electronic cash register according to this embodiment. In the same figure, 1
1 is a CPU (central processing unit) that constitutes the main body of the control unit;
2 is a ROM (read-only memory) in which program data etc. for the CPU 11 to control each part is stored; 13 is a RAM (random access memory) in which various memory areas used for data processing are formed. It is.

Further, in the figure, 14 is a clock circuit that measures the current date and time, 15 is a keyboard controller that receives key signals generated by key inputs on the keyboard 16;
7 is a display controller that drives and controls the display 18;
9 is a printer controller that drives and controls the printer 20, and 21 is an I/O port.

A selection signal is input to the I/O port 21 from a mode switch 22 for selecting various business modes such as "registration", "inspection", "payment", "setting", etc., and a barcode scanner 23 A barcode reading signal is input from. It also outputs an opening drive signal to the drawer 24 for storing cash and the like.

[0012] The CPU 11, the ROM 12, and the RA
M13, clock circuit 14, I/O port 21, and each controller 15, 17, 19 are electrically connected via bus line 25.

As shown in FIG. 2, the keyboard 16 has various keys such as a number key 31, a clear key 32, an amount key 33, a code key 34, a multiplication key 35, a subtotal key 36, and a deposit/total key 37. is installed. The deposit/cash key 37 functions as a closing key for instructing closing of one transaction in the "registration" mode.

The display 18 is for displaying the name and price of the product purchased by the customer, the total price of the customer, and the like. Further, the printer 20 prints out the detailed information and total information of the purchased products on a receipt and a journal, and issues a receipt.

As shown in FIG. 3, the RAM 13 has the following information:
Corresponding to the product code assigned to each product, product information such as the name, unit price, and tax classification (tax excluded = 1, tax included = 2, tax exempt = 3) of the product is preset, and each product a product file 41 having a sales accumulation area for accumulating the number of sales points and sales amount for each product code;
Print buffers 42a, 42b, and 42c are provided for tax types such as tax-exclusive, tax-inclusive, and non-taxable, and a total amount memory 43 stores the total amount of one transaction, and stores the total amount of tax-excluded amount in one transaction. Excluding tax amount total memory 44,
Various memory areas are formed, such as a tax amount memory 45 that stores the tax-excluded amount for one transaction, and a tax-included total amount memory 46 that stores the total amount including tax for one transaction.

[0016] Accordingly, when the barcode scanner 23 performs a reading operation (scanning) of a barcode attached to a product while the mode switch 22 selects the "registration" mode, the CPU 11 performs the following operations. The program is set to execute the scanner registration process shown in FIG.

That is, first, the barcode scanner 2
The barcode read in step 3 is converted into a product code, and the product file 41 is searched using the product code as a key. Then, the product information (product name, unit price, tax classification) corresponding to the product code is read out.

Next, the unit price is multiplied by the number of items sold (if a multiplier has been input by the combination input of the number key 31 and multiplication key 35 immediately before scanning, that multiplier; if not, then "1"). The sales amount is calculated, and the number of items sold and the sales amount are accumulated in the sales accumulation area corresponding to the corresponding product code of the product file 41 (sales registration process). Further, the sales amount is added to the total amount memory 43. Next, the read tax classification is checked. (Means for determining tax type)

[0019] Here, if "tax classification = 1", that is, the product with the corresponding product code belongs to a non-tax product, the detailed data for receipt printing consisting of the product name, number of units sold, unit price, and sales amount is stored in the non-tax print buffer. 42a, and adds the sales amount to the tax-excluded amount total memory 44. If "tax category=2", that is, the product with the corresponding product code belongs to a tax-inclusive product, the detailed data for receipt printing is stored in the tax-inclusive print buffer 42b. “Tax category = 3
'', that is, if the product with the corresponding product code belongs to a tax-exempt product, the detailed receipt printing data is stored in the tax-exempt print buffer 42c. (Tax type detailed information storage means). After that, the product name, sales amount, etc. are displayed on the display 1.
8, this scanner registration process ends.

[0020] Furthermore, the CPU 11 also performs "registration".
In this mode, when the deposit/cash key 37 of the keyboard 16 is inputted, the program is set so that the closing key input process shown in FIG. 5 is executed.

[0021] In other words, the above deposit/
When the current total key 37 is input, first, the non-taxable amount in the non-taxable amount total memory 44 is multiplied by a preset tax rate (for example, 3%) to calculate the non-tax amount, and the non-tax amount is calculated. is stored in the tax amount memory 45. Next, total amount memory 4
The total amount including tax is calculated by adding the total amount in 3 and the non-tax amount in the tax amount memory 45, and the total amount including tax is stored in the total amount including tax memory 46.

Next, the printer 20 is driven and controlled to first print out the receipt printing detailed data stored in the tax-excluded printing buffer 42a on a receipt and a journal. Next, the receipt printing detail data stored in the tax-inclusive print buffer 42b is printed out on the receipt and journal. Next, the detailed data for receipt printing stored in the tax-exempt printing buffer 42c is printed out on a receipt and a journal. (Detailed information printing control means)

Furthermore, the amount in the total amount memory 43 is printed as the subtotal amount, the amount in the tax amount memory 45 is printed as the tax-excluded amount, and the amount in the tax-included total amount memory 46 is printed as the total amount including tax on the receipt and journal, respectively. Once output, the receipt is issued and the drawer 24 is opened. Thereafter, once each of the print buffers 42a, 42b, 42c and each of the memories 43 to 46 are cleared, this close key input process is completed.

In this embodiment having such a configuration, each time a customer reads the barcode of a product purchased by the barcode scanner 23 and registers it as a scanner, the sales data of the registered product is stored in the product file 41 for each product. Along with the sales registration process, the tax type (exclusive tax, tax inclusive, non-taxable) of the registered product is determined. If the registered product is a non-tax product, the tax-exclusive print buffer 42a is used, if the registered product is a tax-inclusive product, the tax-inclusive print buffer 42b is used, and if the product is tax-exempt, the tax-exempt print buffer 42a is used to print the corresponding receipt. Detailed data is stored.

[0025] In this way, when the scanner registration for all the products purchased by one customer is completed, the detailed data for printing receipts for all the products are stored in each print buffer 42a, 42b,
42c, classified by tax type and accumulated. Further, the total amount memory 43 stores the total amount of all products, and the tax-excluded amount total memory 44 stores the total amount of tax-excluded products among all products.

After that, when the deposit/cash key 37 is input to declare the closing of one transaction, first, the tax-excluded amount is calculated from the tax-excluded amount in the total tax-excluded amount memory 44, and the tax amount is stored in the tax amount memory 45. is stored in In addition, the total amount memory 4
The above-mentioned tax-excluded amount is added to the total amount in 3 to calculate the tax-included total amount, which is stored in the tax-included total amount memory 46.

Thereafter, the printer 20 starts printing the receipt, and first, the detailed data for receipt printing in the non-tax printing buffer 42a is printed out. Then,
The receipt printing detailed data in the tax-inclusive printing buffer 42b is printed out. Next, tax-exempt print buffer 4
The detailed data for receipt printing in 2c is printed out. Finally, the amount in the total amount memory 43 (subtotal), the amount in the tax amount memory 45 (excluding tax amount), and the total amount including tax memory 46
The amount (total) will be printed and a receipt will be issued.

FIG. 6 shows an example of issuing a receipt 60 in this embodiment. As shown in the figure, for a customer who has purchased a plurality of products with different tax types, the sales details of each product are classified by tax type and printed on a receipt, regardless of the order in which the products are registered. Therefore, the customer can easily check the tax type of the purchased product just by glancing at the receipt.

[0029] In the above embodiment, the product file 4 is
1 shows a case where a tax classification area is provided and a tax type is set, but the present invention can also be applied to a case where a tax type is specified using a keyboard each time a product is registered. Further, it goes without saying that the classification of tax types and the order of tax types to be printed on a receipt are not limited to this embodiment. Furthermore, the detailed information corresponding to each product registration may be printed out for the journal. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

[0030]

[Effects of the Invention] As detailed above, according to the present invention, product detail information can be printed out on a receipt by tax type without depending on the registration order of products, and the tax type of purchased products can be easily determined from the receipt. We can provide electronic cash registers that can be verified.
