ABSTRACT:
A device for setting a film state for use in a camera having a chamber for storing a film cartridge and a chamber door, and the film cartridge further including a data disk having photographic information recorded thereon. The device includes a photographic information reader which reads the photographic information on the data disk. A door detector detects whether the chamber door is open. A controller determines whether the film is unexposed based upon the photographic information, determines whether the chamber door opens within a predetermined period of time after the chamber door was closed, and outputs a control signal which sets the data disk to an unexposed state if the film is unexposed and the chamber door opens within the predetermined period of time. A transport unit moves the film and sets the data disk based upon the control signal.
