Cash transaction machine and method therefor

摘要

A cash transaction machine includes a sterilizing unit for sterilizing bills by heat, a heating temperature of the sterilizing unit being detected by a sensor and maintained in a specified range, wherein a number of bills to be processed is limited because there is a possibility that if very many bills are processed by the sterilizing unit, the heat is absorbed by the bills and the heating temperature falls, and the germs are not killed effectively, wherein when the bills are not sterilized, the sterilizing unit is operated intermittently to thereby prolong its service life, and the bills are sterilized only when a specified transaction is selected, and wherein a pressure is applied to bills simultaneously with heating by the sterilizing unit to thereby remove folds and rumples of the bills.
