Abstract
A camera is loadable with a film cartridge having a rotary spool connected with a film and a bar code disk rotatable with the rotary spool and provided with a bar code for indicating photographing information of the film. While the rotary spool is being rotated, the bar code on the bar code disk is read by two readers to judge whether the film has been exposed. Code data is generated based on a read signal produced by the readers after the bar code disk rotates together with the rotary spool a predetermined rotation amount after the film is judged to have not been exposed, and is decoded into film information.
