PROBLEM TO BE SOLVED: To improve the operability for customers who are not charged for facility use and to increase the reliability of productivity data regarding the facility use by providing a means which declares free facility use. SOLUTION: A free ticket key 26-3 is provided as the means which declares free facility use. When the free use is declared with the free ticket key 26-3 at the end of use by facility users, the total facility charge calculated from the facility use time of a facility user is deduced and production data on the facility use frequency, facility use time, and facility use charge are accumulated in a box table. Therefore, a customer who is not charged for the facility use only inputs the free ticket key 26-3 before inputting a closing key 25 and the need for troublesome return registering operation after registering operation is eliminated to improve the operability. Further, a customer who uses a free ticket inputs the free ticket key 26-3 at the time of exiting-time registration, so the customer never forgets to input the key. |
