ABSTRACT:
The camera of the present invention includes means for recording and reproducing information regarding the photographed frames of film, means for applying onto the cartridge of a film unit discriminative information indicative of whether the reading-out of the information regarding photographed frames is necessary, means for detecting the discriminative information, and means for controlling whether the reading out of the information regarding photographed frames should be effected in conformity with the result of the detection. Thus, when the camera is loaded with a film unit which does not require the reading-out of the information regarding photographed frames, like a new film unit which has never been loaded into a camera, the operation of reading out the information regarding photographed frames is saved.
