PURPOSE:To secure easy calculation of the using time charge for more thn a week by providing the timing means, key input means, means to memorize various information, arithmetic means, information reading means and others and using the recording medium for the information of the starting time and day for the use. CONSTITUTION:The magnetic card recording the starting time and day for the use is read out through parking ticket reader 14 to obtain the number of the using days for fraction within a week based on the current day of the week, and then the using days and time of the fraction are obtained through arithmetic control unit 21 to store them into timing register R1. Then the using charge less than a week is calculated through unit 21 based on R1, unit-time register R2 and unit-charge register 3 respectivly to be stored in fraction charge register R6. The using charge corresponding to the number of weeks applied through keyboard 11 is calculated to be stored in week register R7. Then the charge is added togethere between R6 and R7 to calutate the using charge for more than a week. |
