Abstract
A film magazine includes a spool which is supported for rotation in a magazine body and around which the roll film is wound, and a data disk which carries bar codes representing information inherent to the film magazine such as the ISO sensitivity, the number of exposure frames and the like of the film and is rotated together with the spool. The spool is held in a predetermined position when the film is completely in the magazine body so that the angular position of the spool relative to the magazine body represents the condition of use of the film. A photosensor is disposed in a fixed position to read the bar codes while rotating the spool and the condition of use of the film is distinguished on the basis of an angle by which the spool is rotated by the time the photosensor reads a predetermined particular point on the bar codes.
