ABSTRACT:
A camera for reading film information expressed with a bar code, which is provided on a bar code plate being rotatable with a spool of a film cartridge, through a window of the film cartridge. The camera includes: a driver for rotating the spool; an optical reading device for reading the bar code, and for generating a bar code information including the film information; a detecting circuit for detecting a reference position of the bar code according to the bar code information, and a memory device for storing the bar code information being read by the optical reading device. In the camera, the driver rotates the spool in a film rewinding direction after a film in the film cartridge is rewound so that the detector circuit detects the reference position of the bar code according to the bar code information stored in the memory device, and the driver rotates the spool according to the reference position so as to locate a bar code portion corresponding to exposed state of the film. The camera further includes a release pin for releasing a spool locking mechanism which cannot be inadvertently released during the cartridge loading or cartridge removal.
