ABSTRACT:
A film cartridge comprising a housing having an outer array of electrically sensible areas which can be sensed by a similar array of electrical probes in a camera, is characterized in that a masking slide is supported on the housing for movement between a non-masking position not covering the outer array of electrically sensible areas on the housing, to permit the electrical probes to sense the respective areas, and a masking position covering at least a portion of the outer array of electrically sensible areas, to prevent the electrical probes from sensing the covered areas. Optionally, the housing has an outer exposed film indicator, and the masking slide covers the exposed film indicator when the masking slide is in its non-masking position and uncovers the exposed film indicator when the masking slide is in its masking position.
