Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic cash register that stores currency exchange rates in its internal storage and allows payment for sold products not only in home currency but also in foreign currency. In particular, the present invention relates to an electronic cash register in which a dedicated drawer is provided for each currency, and each drawer is selectively opened and controlled in response to a closing operation for each currency.

[Prior Art] For example, in European countries where the border is a land border, it is generally possible to shop at shops in cities adjacent to the border using not only the currency of one's own country but also the currency of the neighboring country. . In addition, at duty-free shops at international airports, you can shop in any currency as long as it is the currency of a major country.

As electronic cash registers installed in such stores, the exchange rate of each foreign country's currency against the home currency is stored in the internal memory in advance, so that sales can be registered in units of any foreign currency other than the middle of the home currency. A new version has been developed.

(Patent Application No. 54-102927) [Problems to be Solved by the Invention] However, the above-mentioned example (Patent Application No. 102927-1982)
), the following problems still need to be solved regarding electronic cash registers that can register sales in multiple currencies. In other words, customers pay in a wide variety of currencies. In addition, if the customer pays in foreign currency in excess of the total price of the product sold and receives change for the deposited amount, the money is generally returned in the home currency. Additionally, some items may be returned in the currency of the other country in which they were paid.

As described above, a wide variety of currencies are registered in electronic cash registers, and banknotes and coins corresponding to these currencies are exchanged between customers and cashiers.

However, since electronic cash registers are generally provided with only one drawer, multiple types of currencies including home country currency are stored in one drawer. Further, the number of partitions in the drawer is also limited by the shape of banknotes and coins.

Therefore, since multiple types of currency and multiple types of banknotes or coins are stored in one partition in the drawer, the burden on the cashier increases and there is a risk that the cashier may return the wrong banknote or coin to the customer as change. was there.

In addition, when the day's sales operations are completed and the day's sales amount, sales points, etc. are settled, it takes a lot of time to tally up the cash in the drawer for each currency, and it is difficult to register sales. There was a concern that overall work efficiency would decline.

The present invention has been made based on these circumstances, and its purpose is to provide a dedicated drawer for each currency handled, and to selectively use each drawer in response to closing operations for each currency. By controlling the opening, it is possible to prevent errors in money exchanges with customers, reduce the burden on cashiers, improve work efficiency in sales registration work, and provide an electronic cash register that is reliable for customers and cashiers. be.

[Means for Solving the Problems] The present invention provides an electronic cash register that stores a currency exchange rate in an internal storage section and allows payment for sold products not only in home currency but also in foreign currency. , a foreign currency designation key for inputting the currency type information of the foreign currency paid, and a plurality of thin needle keys for calculating the total amount of products sold to one customer in the corresponding currency unit,
Furthermore, a dedicated drawer is provided for each currency. Then, in response to the key input operation of each fine needle key, the drawer corresponding to the currency of this fine needle key is opened, and the currency to be returned as change when the foreign currency paid exceeds the total amount is opened. A selection means is provided to select either the home country currency or the foreign country's currency, and when this selection means selects the home country currency, it opens the drawer corresponding to this home country currency, and when it selects the foreign country's currency, it opens the drawer corresponding to this foreign country's currency. This allows the drawer to be opened.

[Operation] In the electronic cash register configured as described above, if the paid currency is the currency of another country, the cashier inputs the foreign currency designation key corresponding to this currency, and then inputs the fine needle key of the corresponding currency. Then, the currency drawer corresponding to this fine needle key opens. Additionally, if you select to return the change in your home currency, the drawer corresponding to your home currency will open, and if you select to return the change in the currency in which it was paid, the drawer corresponding to the currency in which it was paid will open. open.

If the subtotal end flag 39 is not yet set to 1,
The $ key flag 34 is checked, and if the $ key flag is not set to 1, the subtotal amount indicated in the home currency unit is directly printed out in the total money order row of the receipt. Further, if the $ key flag 34 is set to 1, the sales amount is converted into the home country currency unit and printed out in the total money order row of the receipt. Then, the sales amount is converted into dollar currency units and displayed on each display section 2.7. After that, set the payment mode flag 40 to 1.
Set to .

When the setting of the payment mode flag 40 is completed, the $ key flag 34 is checked again, and if it is not set to 1, the sales amount is converted to the dollar currency unit and the $ key flag 34 is set to 1.

Next, if there is no deposit operation in dollar currency units, the total sales amount converted into dollar currency units is printed out on a receipt and displayed on each display section 2.7. Next, a payment mode flag 40, a transaction flag 41. $
After the key flag 34 is reset to O, the address stored in the $ drawer address memory 47 of the RAM 15 is read. Then, based on the read address, the $ drawer 6a is opened via the drawer opening bag [23a]. And printer 2
In step 2, the printed receipt is greatly fed, cut, and discharged from the receipt issuing port 4.

Further, when a deposit operation is performed, the deposit amount displayed in dollar currency units is printed on the receipt and displayed on each display section 2.7. If the deposited amount is equal to the sales amount (total amount), each flag is cleared, the $ drawer 6a is opened based on the address of the $ drawer address memory 47, and a receipt is issued. If the deposited amount is larger than the sales amount, the class over flag 38 is set to 1, and then change is calculated in dollar currency units. Next, the state of the dollar fishing flag 43 in the RAM 15 is checked. If it is set to 1, it is necessary to return the change in dollar currency, so the change amount converted into dollar currency units is displayed on the display section 2.7 and printed out on the receipt. Thereafter, each flag is released, the $ drawer 6a is opened, and a receipt is issued.

On the other hand, if the dollar change flag is not set to 1, the change can be returned in the home currency, so the amount of change that was previously converted into the dollar currency unit is converted back into the home currency unit. Then, the basic drawer opening flag 51 in the RAM 15 is set to 1 in order to reserve the opening of the basic drawer 6 in preparation for returning change. Then, the $ drawer 6a is opened to store the dollar currency paid by the customer.

If the deposit amount is less than the sales amount, set $ key flag 3I4 to 0.
, calculate the dollar balance (shortage), convert this balance to the home currency unit, and use it as the new sales amount. Then, this sales amount (deficiency) is displayed on each display section 2.7. Thereafter, the $ drawer 6a is opened to receive the insufficient amount.

When the deposit/total key 8q is input to close the sales registration process for one customer, the flowchart shown in FIG. 13 is executed. First, confirm that the control switch 9 is set to [Registration] business mode, and then
The state of the class over flag 38 of M15 is checked. If the category overflow flag 38 is 1, there is change to be returned, so after confirming that no change has been set and that the basic drawer open flag 51 in the RAM 15 is set to 1, press the dollar cash total key shown in FIG. The amount of change converted into the home country currency obtained by the key processing in step 8j is displayed on the display section 2.7 and printed out on the receipt. Then, the basic drawer 6 is opened using the drawer opening device 23, and a printed receipt is issued at the same time.

If the category overflow flag 38 in the RAM 15 is not set to 1, there is no need to return the change, or the payment was made in the home currency rather than the foreign currency, and the keys 8j to 8m of the foreign currency currency are used. It is determined that the deposit/cash key 8q has been operated without any input operation. That is, after confirming that a transaction is in progress and that all foreign currency key flags 34 to 37 are cleared to 0, if a deposit operation is performed, it is confirmed that the deposit amount is not 0. If the system is in the payment mode, the subtotal end flag 3-9 is checked, and if it is not set to 1 yet, the total amount is printed on the receipt. Further, if the subtotal end flag 39 has already been set to 1, the subtotal end flag 39 is reset to 0. after that,
Set the payment mode flag 40 to 1.

When the setting of the payment mode flag 40 is completed, if a deposit operation has been performed before the operation of the deposit/total key 8q, the deposit amount is printed on the receipt and displayed on each display section 2.7. If the deposit amount matches the sales amount (total amount), the basic drawer 6 is opened, each flag is canceled, and a receipt is issued. If they do not match, and the deposit amount is greater than the sales amount, the amount of change in home currency is calculated, displayed, and printed. And basic drawer 6
At the same time, each flag is released and a receipt is issued. If the deposited amount is less than the sales amount, the balance (deficiency) is calculated and displayed on the display section 2.7 as the new sales amount.

In addition, if there is no deposit operation, the total amount will be displayed on display 2.
7 and stamp the receipt, the basic drawer 6 is opened, each flag is canceled, and a receipt is issued.

In the electronic cash register configured in this manner, the exchange rate of each foreign currency against the home currency is stored in each rate memory 30 to 30 of the RAM 15 before starting sales registration operations.

Only the drawer of the currency specified in step 46 is opened. Therefore, since drawers that are not related to the exchange of money are not opened, the cashier can prevent received banknotes or coins from being stored in the drawer of the wrong currency, and will not return change of the wrong currency. As a result, the burden on the cashier can be reduced and the efficiency of sales registration work can be improved. Furthermore, the efficiency of aggregating each currency accumulated in the drawer during settlement operations can be improved.

In addition, when a customer receives change for the foreign currency they paid, they can choose in advance whether to return the change in Honda currency or the foreign currency they paid in, as necessary.
Furthermore, it is possible to display the amount of change in any currency on the display section 2.7 and to print it out on the receipt. Therefore, the cashier does not need to use a calculator or the like to convert the amount of change into the currency unit of the payment currency, which further reduces the burden on the cashier and improves the efficiency of sales registration work.

Furthermore, since the amount of change is automatically calculated in the currency of the country in which it was paid, the electronic cash register can be trusted by both customers and cashiers.

[Effects of the Invention] As explained above, according to the present invention, a dedicated drawer is provided for each currency handled, and each drawer is selectively opened and controlled in response to the closing operation for each currency. There is. Therefore, errors in money exchange with customers can be prevented, the burden on the cashier can be reduced, work efficiency in sales registration work can be improved, and an electronic cash register that can be trusted by customers and cashiers can be provided.
