2. Description of the Related Art In a merchandise sales data processing device comprising, for example, an electronic cash register, after a merchandise item has been registered for a customer purchase, when a subtotal key is pressed, for example, the total amount thereof is obtained and displayed on a display. Upon seeing this, the customer hands over the currency equivalent to the displayed total amount to the cashier. The cashier confirms the received currency, and then inputs the deposit amount using the numeric key.

Thereafter, under the condition that a closing operation (for example, an operation of pressing a deposit / current total key) is performed as necessary, a change amount is automatically calculated when the inputted deposit amount is equal to or more than the total amount. The automatically calculated change amount is also displayed. The cashier who sees this takes out the currency equivalent to the change amount from the automatically opened drawer and hands it to the customer. A receipt is also handed. Here, the checkout ends.

[0004]

Incidentally, after the change amount is automatically calculated, the customer may hand a fractional amount. For example, the total amount is 1985 yen and the deposit amount is 2000
In the case of yen, a change amount of 15 yen is automatically calculated, and thereafter, the customer sends out three 10-yen coins and five 1-yen coins.

In such a case, the cashier checks the displayed change amount of 15 yen and is taking out one 10-yen coin and one 5-yen coin (or five one-yen coins) from the drawer.
If three 10-yen coins and five 1-yen coins are sent in the middle, 2035 yen is calculated by adding 35 yen to the deposit amount of 2000 yen, and 50 yen is calculated by subtracting the total amount of 1985 yen from the 2035 yen. Must be sought. Therefore, it becomes complicated, and the business efficiency is greatly reduced, especially when the store is busy.

In addition, the change amount automatically calculated (15 yen)
And the total price (2000 yen) are not displayed together, the total amount (2000 yen) of the destination that is not displayed must be checked in order to obtain a new change amount, so that it takes more time and effort to wait for the customer. Becomes longer. In addition, mistakes in mental arithmetic tend to occur. That is, customer service deteriorates. Furthermore, not only in the case of cash, but also in the case where coupons with a well-separated denomination (for example, 1000 yen, 2000 yen,...) Are frequently used, the opportunity to calculate a new change amount is increasing. I have.

An object of the present invention is to provide a merchandise sales data processing device capable of calculating a new change amount quickly and accurately.
