Method of accepting print order

摘要

A magnetic track on a photographic film is provided with a record region in which a renewal code or a flag indicating that a processing for an order to be completed is recorded. When print order information is renewed, the renewal code or the flag is renewed or cleared. As a result, it can be automatically judged whether the print order information recorded in the magnetic track is the same as one at the time of a previous order, and a processing at a laboratory can be automatically carried out. The print order information is classified into plural types of information including information to be rewritten for every order and information not to be rewritten for every order. At a laboratory, the print order information to be rewritten for every order is automatically deleted or reset before returning the photographic film to the user.
