<p>PURPOSE:To correct a system error, to prevent the carelessness and malfeasance of a crew, and to improve reliability when the crew performs a mis-operartion or erroneous input by managing so as to handle a tariff calculation value by sales index data prferentially. CONSTITUTION:A clearing amount is caluculated based on tariff system data stored in advence in a tariff system storage means 13 and sales index data at every sale stored in an index storage means 12. It is decided whether or not the amount is correct by checking whether or not it coincides with the clearing amount by tariff data stored in a storage means 2 by performing collation computation. When a collation decision result by a collation arithmetic means 14 in which the decision result is stored shows noncoincidance, a receipt is issued by a printer 9 assuming that a tariff based on the sales index data is a valid one. Furthermore, when sales is over, the aggregate of the sales index data and sales amount are calulated based on recorded data, and they are print-outputted on the printer 9 as a sales daily report.</p> |
