An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a CPU (Central Processing Unit) constituting a control unit main body. A ROM (Read Only Memory) 2 in which program data of the processing performed by the CPU 1 is stored, and a RAM (Random Memory) in which a memory used when the CPU 1 performs the processing is formed.
The access memory 3 and the CPU 1 are connected by a system bus 4.

The RAM 3 stores product information such as the product name and unit price of each product as a PLU file.

The CPU 1 is connected to an A / D converter 6 for converting voltage data obtained by weighing by a load cell 5 for measuring the weight of a weighed product into digital data.

The load cell 5 and the A / D
The converter 6 forms a weighing unit.

An I / O (input / output interface) block 7 is provided with a thermal printer 8 for printing a label, a keyboard 9, and a lamp indicating an operation state, and further displays a product name, weight, unit price and price. Display block 10, inline interface 11
And a hand scanner 12 for reading a barcode printed on a label.

As shown in FIG. 2, the keyboard 9 is provided with a label issuing key 9a as a cash payment key, a prepaid key 9b as a prepaid payment key, a one-touch key 9c used for designating a product, and the like. Have been.

The in-line interface 11 comprises:
Prepaid R / W for reading and rewriting information of a prepaid card ( card having value information)
(Reader / writer) 13.

FIG. 3 shows a flow chart of the main part processing performed by the CPU 1.

First, when the power is turned on, the memory of the RAM 3 is cleared and initialized.

Subsequently, initialization is performed at each output terminal of the I / O block 7 based on the initial settings stored in advance.

Subsequently, a segment check of the display block 10 is performed.

Next, it is determined whether or not there is a key operation. If there is no key operation, the balance data obtained from the load cell 5 via the A / D converter 6 is read, the balance data is processed, and an auto-zero process for stabilizing the balance of the balance is performed. If there is a key operation, key processing described later is performed.

In any of the above cases,
It is determined whether the net (content) calculation is necessary. When the weighing data is not “0” and the net is not calculated, the net calculation is necessary, the weighing value obtained by the load cell 5 is calculated from the weighing data as gross, and the weight of the tare is calculated from the gross. Subtract to calculate the net. When the net has already been calculated or when the scale data is “0”, it is determined that the net calculation is not necessary, and the next processing is performed as it is.

Next, it is determined whether price calculation is necessary. If the product has been designated by the hand scanner 12 or the one-touch key 9c but the price has not been calculated yet, the price must be calculated. The net is multiplied by the unit price to calculate the price, and the decimal part is truncated. The price rounding process is performed. Further, when the product is not specified by the hand scanner 12 or the one-touch key 9c or when the price has already been calculated, it is determined that the price calculation is not necessary, and the next process is performed as it is.

Next, the lamp of the display block 10 indicating the currently operated state is turned on, and displayable items among the product name, weight, unit price and price are displayed on the display block 10, and there is a key operation. It returns to the process of determining whether or not it is.

FIG. 4 shows a flowchart of the key processing. First, it is determined whether or not the input by the hand scanner 12 or the key input by the one-touch key 9c is performed. When either of the inputs is performed, the product information of the product specified by the input is stored in the RAM 3. Search and read from PLU file. Subsequently, the product name and the unit price of the specified product obtained from the product information are displayed on the display block 10, and the key processing ends.

If the input by the hand scanner 12 or the key input by the one-touch key 9c has not been performed, the prepaid key 9b or the label issuing key 9a
It is determined whether or not a key input has been performed.

If neither key input by the prepaid key 9b nor the label issuing key 9a has been performed, other key processing is performed.

When the key is input by the label issuing key 9a, it is checked whether or not the price has been calculated. If the price has not been calculated, this key processing is terminated.
When the price has been calculated, the cash payment label is issued by the thermal printer 8 and the key processing is terminated.

Further, when a key is input by the prepaid key 9b, it is checked whether or not the price has been calculated. If the price has not been calculated, the key processing is terminated. Then, it is determined whether or not a key input by a label issuing key has been performed.

At this time, when the key input by the label issuing key 9a is performed, as a cancellation of the prepaid payment, a paid label corresponding to the amount paid by the prepaid card is issued by the thermal printer 8, and the paid printer is issued. When the label is removed and the label can be issued, the unprinted remaining label is subsequently issued by the thermal printer 8.

If the key input by the label issuing key 9a has not been performed, the operation waits for key insertion by the label issuing key 9a to insert the prepaid card into the prepaid R / W 13 or to cancel the prepaid payment.

The prepaid card is a prepaid R / W13
When the payment is inserted into the prepaid account, a consumption tax is added to the price of the designated product, and the calculated total amount is subtracted from the amount read from the prepaid card by the prepaid R / W13. The prepaid R / W 13 writes the subtracted amount on the prepaid card. (Reader / Writer Control Means) Next, in the prepaid settlement process, it is determined whether or not the amount read from the prepaid card has reached the payment amount of the designated commodity.

When the amount read from the prepaid card has not reached the payment amount of the designated product, the key is again inserted by inserting the prepaid card into the prepaid R / W 13 or by using the label issuing key 9a for canceling the prepaid payment. It returns to the state of waiting for input. Also, when the amount read from the prepaid card has reached the payment amount of the specified product, a label for the payment amount is issued by the thermal printer,
This key processing ends.

FIG. 5A shows an example of the cash payment label issued as described above. FIG. 5B shows an example of the payment amount label. The cash payment label has not been subjected to consumption tax calculation, and the "price" calculated from the "unit price" and "contents" is also printed on the "total amount". In addition, the label for the amount of payment is printed with "consumption tax", the sum of "price" and "consumption tax" is printed on "total amount", and an identification mark of "paid" is printed. Have been. Although not shown, the label formats of the paid label and the balance label conform to the label formats of the paid label and the cash payment label, respectively.

In this embodiment having such a configuration, when the customer sets the weighed product on the weighing unit, the weight of the weighed product is measured and the weight is displayed on the display block. Next, when the customer inputs the product name using the hand scanner 12 or the one-touch key 9c, the product information of the weighed product is called up, the product name and the unit price are displayed on the display block 10, and the tare is determined from the weight. Is subtracted and the price is displayed.

When the customer wants to use the prepaid card, the user turns on the prepaid key 9b and inserts the prepaid card into the prepaid R / W 13, and the customer pays out the money stored in the prepaid card and consumes the amount stored in the prepaid card. If the amount is more than the tax included, the payment will be made on the spot, a label will be issued for the payment amount with the “paid” identification mark printed, and free for customers checking out at stores where payment is made in cash. It will be a path. If the amount stored in the prepaid card is less than the payment amount including the consumption tax, the label issuing key is turned on, and the paid amount label corresponding to the amount paid by the prepaid card and the remaining amount corresponding to the insufficient amount are paid. A minute label will be issued, and at checkout, only the remaining amount label will be settled in cash.

When the customer pays the entire amount of the payment in cash, by turning on the label issuing key, a cash payment label without consumption tax calculation is issued,
At checkout, the consumption tax calculation is performed on the cash payment label, and the cash payment is settled.

As described above, according to the present embodiment, when the customer wants to settle the payment with the prepaid card, the customer sets the prepaid key to O.
Just by performing N, the payment including the consumption tax by the prepaid card is performed, and a label corresponding to the payment amount printed with an identification mark of “paid” indicating that the payment has been performed is issued.

By turning on the label issuing key even if the prepaid card runs short, the paid label for the settlement by the prepaid card and the label for the remaining balance can be issued and dealt with.

Of course, even if the customer wants to pay by cash as usual, a cash payment label can be issued and turned on by turning on the label issuing key.

Therefore, the customer who wants to pay by the prepaid card can have the customer pay the prepaid card and issue a label indicating the payment by the prepaid card. Therefore, the clerk's checkout work at checkout can be reduced.

Of course, it is possible to respond to customers who want to pay cash, and customers who want to pay both by prepaid card and cash.
