Identification data are referred to (S36). Whether or not the character is 1 which indicates a working date is decided (S38). When the decided result is positive, the working count value of a working counter is added by 1 (S42). Whether or not the working count value to which 1 is added is made coincident with an obtained read time is decided (S44). When the decided result is positive, a pointer is shifted from the position of the order date only by a calendar count value on the working date management table 200. Therefore, the delivery date is calculated in the format of a date based on the position of the delivery date (S46).;COPYRIGHT: (C)2000,JPO
