<p>The electronic cash register stores monetary transaction information for each guest in the first memory (1) by entering it with the input means (1), and when a totalization operation is specified by the first specifying means (10), the electronic cash register sums up the amount of money stored in the first memory (13) and adds a result of the calculation to the data in the second memory (15). When entering monetary transaction information for a guest is temporarily ended and there is possibility of reentering the transaction information, the cash register keeps the transaction process in the temporary totalization state, namely, keeps the data stored in the first memory (13) without clearing it as summing up the amount of money stored in the first memory (13) and adding its calculation result to the data in the second memory (11), and then, when an additional registration is specified by the third specifying means (9), the cash register subtracts the calculation result in the first memory (13) from the value stored in the second memory (15), and stores the additionally registered transaction information from the input means (1) in the first memory (13) as an additional registration. Accordingly, when registration of its additional order is performed in a restaurant after registration of a new order was performed, the cash register can print both monetary transaction information of a new order and its additional order together on a single slip (5) on the basis of the data stored in the first memory (13).</p> |
