Abstract: When a car is to enter a parking lot, an image of a number plate of the car is picked up by an image pickup device, and a car number of the car is recognized. The recognized number and the entry time are stored in a central processing unit, and a parking ticket is dispensed for the car, and the car is allowed to enter the parking lot. If there is any service to be offered to customers at the time of parking, service information is inputted to the central processing unit directly from a service counter, and therefore the central processing unit effects a service processing such as a parking fee discount processing. The image of the number plate of the departing car is picked up, and the car number is recognized, and it is judged whether or not the car is entitled to the fee adjustment.
