Abstract
Abstract In the disclosed camera, a reading device in the camera body's cartridge chamber reads electrically sensible data from a cartridge by determining the existence of data at one location of a data carrying surface on the cartridge and optically reading the remaining electrical data at the location of another data carrying surface. A positioning device positions a movable carrier member which holds optical detecting elements a specific distance form the other data carrying surface. Preferably the determination of the existence of data is performed by electrically contacting the one location of the data carrying surface.
